DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for centrally managing a plurality of electric devices including different types, for example, lighting devices, air conditioners, televisions, and the like by wireless communication.

[0002]

2. Description of the Related Art With the spread of various convenient and inexpensive electric appliances, heating appliances such as air conditioners and electric stoves, various cooking appliances, televisions, cassette recorders with radios, video devices, Audio-visual equipment such as Sleteleo set, etc.
Many electric devices are arranged and used. But,
Naturally, many of these electrical devices are basically controlled individually.Even if a remote controller is provided, go to the place where each device is located and use a dedicated controller. You have to control. And as the number of electrical devices increases, for example, it takes a lot of time to turn on the power of each device, set an operation timer, and cut off the power supply to each electrical device when unnecessary, The number of remote controllers also increases.

Under such circumstances, proposals for a home automation system for centrally managing many electric devices have been started.

On the other hand, various sensors are installed inside and outside the building for security monitoring at home or office,
A security system has been realized that remotely manages smoke and flame detectors, intruder detection, and the like.

[0005]

However, in a normal centralized management system, control signals are directly exchanged between the electrical equipment to be controlled and the centralized management device. Circuit must be provided. For this reason, in order to make electrical equipment compatible with the system, it is necessary to change the design of general-purpose electrical equipment, and furthermore, equipment dedicated to the system requires the above-mentioned dedicated circuit, which increases the cost of the equipment. Unavoidable.

[0006] On the other hand, there are cases where the purchaser of the electric equipment does not want to install the system and only wants the original functions of the electric equipment, or when he has already introduced a different type of system. is assumed. In such a case, the purchaser does not need a special function for system compatibility of electrical equipment, and because it is compatible with the system,
Highly priced electrical equipment may not be attractive.

[0007] Further, if it is necessary to replace all existing non-system-compatible electrical equipment with system-compatible electrical equipment in order to introduce a centralized management system, that is, if it is necessary to replace the electrical equipment, economical burden for introducing the system is required. Is very large, and there is a problem that the system is difficult to spread.

On the other hand, if only electrical equipment compatible with the system can be managed, only a small-scale system can be constructed, and the centralized management system cannot be effective.

[0009] Furthermore, in the above-mentioned security system and the like, large-scale construction such as installation work for sensors and communication devices and wiring work is required when introducing the system, and the introduction cost itself is often high. .
Therefore, introduction of the system is not considered unless the building is newly constructed. Therefore, also in this case, it is difficult to increase the system penetration rate.

In order to solve the above-mentioned problems, according to the present invention, a centralized management system for devices is low in cost and easy to introduce. Further, not only system-compatible electric devices but also non-system-compatible electric devices can be managed. The aim is to provide a possible management system.

[0011]

To achieve the above object, the present invention has the following features.

The present invention relates to a system for centrally managing a plurality of electric devices, comprising: a centralized device for managing target electric devices by a wireless communication function; A terminal device for a managed device that outputs a predetermined device control signal based on wireless communication with the device central management device for the electrical device, and further, the managed device terminal device and the management target. An electrical power control device that is interposed between the electrical devices to be managed, receives the device control signal from the managed device terminal device, and controls operation power supply to the electrical device to be managed. It is a feature.

The present invention also relates to a device power control device, which is used in a system for centrally managing a plurality of electric devices by a device centralized management device via a terminal device for managed devices. Outputting a predetermined device control signal for controlling the electrical device to be managed based on wireless communication between the electrical device to be managed and the device centralized management device registered in the device centralized management device Interposed between the managed device terminal device and the device control signal from the managed device terminal device, and controls the operation power supply to the managed electrical device. Is what you do.

As described above, in the system of the present invention, wireless communication is performed only between the device central management device and the terminal device for managed device registered in the device. Therefore, a wireless transmission / reception mechanism is not required for each electric device to be managed, and the production cost of the electric device at the time of introducing the system can be kept very low even if there is no increase.
Further, in the present invention, the device power supply control device is interposed between the managed device terminal device and the electric device. Therefore, even if the electrical device to be managed has a configuration that does not support the system, the device power control device supplies the operating power to the device that does not support the system in response to the control command from the managed device terminal device. By performing the control, the operation of the electric device can be substantially controlled from the device central management device.

Further, in the present invention, the device power supply device includes:
A switch unit that switches between conduction and non-conduction of a power supply path between a predetermined operation power supply and the electric device to be managed; a switch control unit that controls the switch unit; A detection unit for detecting a conduction state;
Comprising, according to the device control signal from the terminal device for managed device correspondingly arranged, the switch control unit controls the switch unit, conduction of the power supply path,
Non-conduction is controlled, and the conduction or non-conduction state of the power supply path detected by the detection unit is transmitted to the corresponding managed equipment terminal device.

As described above, when the device power supply device not only controls the conduction and non-conduction of the power supply path between the operating power supply and the electric device but also detects the conduction and non-conduction state, the device is to be managed. The operating state of the electric device can be detected almost certainly. The fact that the power supply path is non-conductive means that the power supply between the operating power supply and the electric equipment is controlled by the switch unit controlling the supply path to be non-conductive or by turning off the switch of the electric equipment body. Indicates that the supply route is broken. The fact that the power supply path is in the conductive state means that the switch unit controls the conduction of the power supply path, and that the switch of the electric apparatus main body is turned on, so that the power supply path between the operation power supply and the electric apparatus is turned on. Indicates that is conducting. Therefore, if the conduction / non-conduction state of the power supply path is detected, this is transmitted to the centralized management device via the terminal device for the managed device, and the centralized management device is turned on / off of the electric device. That is, it is possible to know the on / off state of the operation and manage the state.

The present invention also relates to a system for centrally managing a plurality of electric devices, comprising a device centralized management device for managing a target electric device by a wireless communication function, and a device registered and managed in the device centralized management device. A managed device terminal device for outputting a predetermined device control signal to a target electrical device based on wireless communication with the device centralized management device, and further, the managed device terminal device and the management device Interposed between the target electrical device, receiving the device control signal from the managed device terminal device, a device power control device that controls the operation power supply to the managed electrical device,
Comprising, the managed device terminal device connected to a system-compatible electrical device, the device centralized management device, the system-compatible electrical device via the managed device terminal device connected to the device Manages, connects the device power control device to the system-compatible electrical device, connects the managed device terminal device to the device power control device, and the device central management device controls the system-incompatible electrical device. The device is managed via the device power control device connected to the device and the managed device terminal device connected to the device power control device.

Regarding the electric equipment corresponding to the system,
By associating the above-mentioned terminal device for a managed device by connecting or the like, this device can be controlled by the terminal device for a managed device. In addition, the device power control device can be controlled by the managed device terminal device by associating the managed device terminal device with the device power control device in the same manner as other system compatible electrical devices by connecting the managed device terminal device or the like. Accordingly, the management system by the centralized management device can be arbitrarily assigned to both the system-compatible electrical device and the system-incompatible electrical device by directly associating the managed device terminal device or indirectly via the device power control device. Can be incorporated into Therefore, the user can construct any centralized management system at his own will.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention (hereinafter, referred to as embodiments) will be described below with reference to the drawings.

[System Configuration] FIG. 1 conceptually shows the configuration of a centralized device management system according to an embodiment of the present invention. In this centralized management system, a device centralized management device (hereinafter, referred to as a host unit) 100 has a function of a host computer for centrally managing electrical devices. The managed devices managed by the host unit 100 include, for example, home electric appliances such as electric rice cookers and irons, various electric devices that are used daily in homes or offices, such as televisions, videos, cassette decks with radios, and the like. is there. Further, in the present system, the electric devices are not limited to the devices whose power sources are all electric power, and operate by power other than electric power, such as an oil fan stove, but the control of the devices is performed electrically. Centralized control is also possible for controlled devices.

In the present system, a small terminal device for a managed device (hereinafter, referred to as a terminal unit) 200 is interposed between the corresponding electric device and the host unit 100 separately from the electric devices to be managed. . Each electrical device corresponding to the present system is provided with a receptacle (terminal insertion section) to which the terminal unit 200 can be connected. By inserting the terminal unit 200 into this receptacle, the host unit 100 is inserted. Via the terminal unit 200, the power supply of the electric device and other functions are controlled.

However, there are cases where the electric equipment to be managed does not correspond to the system. If the terminal unit 200 cannot be mounted on the electric device, the electric device cannot be controlled via the terminal unit 200.

Therefore, in the system according to the present embodiment,
Even if the electric device does not support the system, the electric device can be controlled via the terminal unit 200. The control of the electric equipment which is not compatible with the system is performed by a power control unit 400 which directly controls the supply of the commercial electric power which is the operation power supply to the electric equipment between the electric equipment and the terminal unit 200.
Is realized by interposing

The power supply control unit 400 has a terminal plug-in unit, and the same terminal unit 200 as the terminal unit 200 mounted on the system-compatible electric equipment can be mounted on this terminal plug-in unit. Then, as shown in FIG. 2, the power supply control unit 400 converts the power supplied from the commercial power supply into the A of the electric device.
C, a supply path to be supplied to the power outlet, a switch unit (here, a relay) 80 provided in the supply path for switching the supply path on and off, and a switch unit in accordance with a control signal from the terminal unit 200 mounted. The power supply control unit 82 controls opening and closing of the power supply 80.

The power supply control unit 400 has the terminal unit 2
When the terminal unit 200 receives a control signal from the host unit 100, the corresponding control data is transmitted from the terminal unit 200 to the power supply control unit 40.
Informed to 0. Therefore, the power supply control unit 400 controls the opening and closing of the switch unit 80 according to the data to directly control the supply of the commercial power to the electric device.

By using the power supply control unit 400 as described above, even if a plurality of electrical devices that are to be centrally managed do not correspond to the system, the power supply control unit 400 can be controlled via the terminal unit 200. Thus, it is possible to control the power supply of the electric equipment that is not compatible with the system from the host unit 100 side.

Each terminal unit 200 and host unit 1
The communication with 00 is performed by setting both units as local radio stations.
For example, digital wireless communication using a band (specific low power) of about 230 to 240 MHz or 400 MHz is performed. However, if the control is performed within a narrow range, wireless communication by a weak wireless station, infrared communication, and the like are also possible. By adopting wireless communication, even if this system is introduced, each electric device can be controlled by the wireless communication between the host unit 100 and the terminal unit 200 and the power supply control unit 400 when the system is not compatible. There is no need to perform wiring work, etc. As will be described later, an individual unique 32-bit code (hereinafter referred to as an ID code) is allocated to each terminal unit 200 at the time of manufacture, as will be described later, and the host unit 100 identifies and controls each terminal unit 200 using the ID code. The ID code of the terminal unit 200 can be registered in the host unit 100. After registering the ID code, the terminal unit 200 is inserted into the system-compatible electric device among the devices desired to be incorporated into the centralized management system. In the case of a non-system compatible electric device, the power plug of the electric device is inserted into the power control unit 400, and the terminal unit 200 is inserted into the power control unit 400. As a result, the device is managed by the host unit 100 via the terminal unit 200 in the case of a system compatible device, and is managed by the host unit 100 via the power supply control unit 400 and the terminal unit 200 in the case of a system non-compliant device. Note that wireless communication between the host unit 100 and the terminal unit 200 is preferably performed using, for example, spread spectrum communication or the like in order to prevent malfunction of other electronic devices.

When the ID code of the host unit 100
The terminal unit 200 registered in is registered in the electric device or the power supply control unit 400, and is always in a state where a transmission signal from the host unit 100 can be received. The terminal unit 200 is connected to the host unit 1
When a control signal with its own ID code is received from 00, the control signal is recognized as a control signal for itself and control of the corresponding electric device or control of the switch unit 80 of the power supply control unit 400 is performed. When the control is executed, a completion report or the like is transmitted to the host unit 100.

Even if the host unit 100 transmits a control signal to a specific terminal unit 200, if there is no response from the terminal unit side, the transmission is executed several times. If there is no response from the terminal even after performing the retry,
The host unit 100 displays “no response” or “impossible to transmit” on the display panel 10 as a warning message for the electric device corresponding to the ID code.

The terminal unit 200 automatically
Alternatively, in response to a request from the host unit 100, the state of the corresponding electric device (for example, the power on / off state) is reported to the host unit 100. Power control unit 400
Although the terminal unit 200 connected to the power control unit 40 cannot directly know the state of the electric device,
0 of the switch unit 80 of the host unit 100
Report to

The host unit 100 stores the obtained status of each device, and displays the stored status when the system user selects the device. For example, when “illumination in a child's room” is selected by the host unit 100, if the power status reported so far is illumination on, “illumination on” is displayed. When "living air conditioner" is selected, for example, if the reported state is off, "air conditioner off" is displayed. Alternatively, when a “door closing” is selected in the host unit 100 by using a door closing sensor or the like as an electric device or using a sensor with a terminal function, for example, “kitchen entrance entrance item” is displayed.

From the power control unit 400 to the switch unit 8
When the open / close state of 0 is obtained, the host unit 100
For example, when the switch unit 80 is open and the power supply to the electric device is off, “unit off” is displayed. When the switch unit 80 is closed and the power supply to the electric device is on, “unit off” is displayed. "ON" or the like is displayed on the display panel 10.

When the switch section 80 of the power supply control unit 400 is controlled to open, if the power supply path between the commercial power supply and the electric equipment is non-conductive, no operation power is supplied, and the electric equipment is turned off. doing. On the other hand, if the switch unit 80 is controlled to be closed, the power supply path is conductive, so that the operation power is supplied, and the electric device is on unless the power is turned off on the electric device main body side. Therefore, the open state and the closed state of the switch unit 80 of the power supply control unit 400 can be regarded as the off and on states of the electric device, respectively. Therefore, the host unit 100 converts the open / closed state obtained from the power control unit 400 via the terminal unit 200 into the power control unit 4.
It is also possible to consider that the device connected to 00 is off and on, and to display “XX device off”, “XX device on”, and the like.

As described above, through the terminal unit 200 or the power supply control unit 400 and the terminal unit 20
If the status of the electrical device to be managed is reported to the host unit 100 via the “0”, the system user can know the status of the electrical device to be managed from the display panel 10 of the host unit 100. Further, depending on the state, even if each device is located in another place, the host unit 100 can issue an appropriate control command. However, when the open / close state of the switch unit 80 in the power control unit 400 cannot be directly detected, the switch on / off control signal supplied to the switch unit 80 may be displayed as the open / close state of the switch unit 80. Good.

The EEPROM 18 is a storage unit that stores the above-described ID codes of the terminal units 200 and the settings for centralized management, and registers the read ID codes of the terminal units 200. The microcomputer 12 is a centralized control unit, and includes a wireless transmission / reception unit 20, an LCD driver 14, an operation unit 16, and an EEPROM.
While managing the M18, the terminal unit insertion section 26, etc.,
Each terminal unit 2 by wireless communication via the antenna 24
00 is managed.

Next, the configuration of the terminal unit 200 will be described. 5 and 6 show a schematic configuration of the terminal unit 200. The terminal unit 200 includes a wireless transmission / reception unit 32, a filter 34, and a built-in antenna 36 as a communication unit for performing wireless communication with the host unit 100. Also, the overall operation of the terminal unit 200 is managed,
The microcomputer 30 generates a signal for controlling the connected electric device or the power supply control unit 400, and detects a state of the electric device and generates a signal for notifying the host unit 100. Further, it has a buffer 38 for temporarily storing data to be transmitted and received.

The terminal 50 of the terminal unit 200 is composed of two insertion terminals,
Can be inserted into the terminal insertion section 40 provided in the terminal.
Each of the two insertion terminals is electrically separated into two by an insulating separation portion 60, and the terminal 50 is constituted by a four-pole terminal. When the internal power supply is not provided in the terminal unit 200, the GND terminal 52, the DATA terminal 54,

The terminal unit 200 provided in the electric equipment and power supply control unit 400 includes the terminal unit 200.
Terminal (VDDS (VDD Supp
ly) terminal, PC terminal, DATA terminal, GND terminal). When the terminal unit 200 is inserted into the terminal end insertion part 40 of the electric device or the power supply control unit 400, if there is no built-in power supply, first, the V
The device is activated by receiving power supply from an electric device via the DD terminal 58. Thereafter, the terminal unit 200 transmits the DATA
From the terminal, the power status of the electric device and the power control unit 400

Then, the detection result is voluntarily reported as described above or in response to a status report request from the host unit 100, and the power ON / OFF state of the detected device is reported together with its own ID code. The terminal unit 200 is connected to the host unit 10.
When a control signal from 0 is received, a device control signal corresponding to the control signal is sent to the electric device via the DATA terminal 54. Also, a control signal may be sent to the power control unit 400 using a PC terminal, as described later. As a result of the control, on / off of the power of the system-compatible electric device is controlled, and conduction and non-conduction of the power supply path by the power control unit 400 are controlled for the non-system-compatible electric device. Note that the terminal unit 200 may transmit the control signal transmitted from the host unit 100 as it is to the electric device or the power control unit 400 as a device control signal.

When the system-compatible electric equipment has an extended function that can further manage special items by the centralized management system, the terminal unit 200 attached to the electric equipment is connected to its DATA terminal 54 via its DATA terminal 54. The presence or absence of the extended function of the device is automatically detected and sent to the host unit 100 together with the contents of the function.

[Detection of State of Electrical Equipment by Power Control Unit] In the configuration of FIG. 2, the terminal unit 200 connected to the power control unit 400 is a switch provided on a path from a commercial power supply to a non-system compatible electrical equipment. Part 8
It only detects opening and closing of 0, and cannot directly detect the power state of the electric device. Power control unit 400
When the switch unit 80 is open, the electric device is turned off because the power supply from the commercial power supply is cut off, and the open state of the switch unit 80 corresponds to the off state of the electric device. However, when the switch unit 80 is in the closed state and the power switch of the electric device main body is turned off (switch open), the electric device is turned off. Therefore, the switch unit 8
The closed state of 0 and the turning on of the electric device do not always match.
When the switch of the main body of the electric device is turned off (open) while the switch unit 80 of the power supply control unit 400 is in the closed state, the configuration of FIG. 2 cannot detect this.

FIG. 7 shows a power supply control unit 40 for detecting the on / off state of the electric equipment in such a situation.
0 is shown. The power supply control unit 400 includes, in a supply path between the commercial power supply and the electric device, a switch unit 80 that controls conduction and non-conduction of the supply path, a light emitting element 86 that emits light in accordance with on / off of the supply path, Is provided. In addition, a power supply control unit 84 that controls opening and closing of the switch unit 80 in accordance with a control signal from the connected terminal unit 200 and detects on / off of a supply path based on light emission of the light emitting element 86 is provided. This power control unit 84
Includes a coil C1 for controlling the switch, two-stage transistors Q1 and Q2 for driving the coil C1, and a photodiode 88 that operates in response to the light emitting element 86 emitting light.

When connected to the power supply control unit 400, the terminal unit 200 recognizes this, and outputs a control signal for driving the coil C1 from its PC terminal based on an instruction from the host unit 100. I do. PC
When a predetermined H-level control signal is supplied to the terminal, the transistor Q1 current-amplifies the control signal, and the transistor Q2 is driven by the amplified current, and the transistor Q2 operates to supply a current to the coil C1. . Coil C1
, The switch unit 80 is opened, and the power supply path to the electric device is turned off. Also,
When a predetermined L-level control signal is supplied to the PC terminal,
The transistors Q1 and Q2 are turned off, no current flows through the coil C1, and the switch unit 80 is closed. As a result, the power supply path to the electric device is conducted.

Here, when the switch unit 80 is closed, if the power switch 90 of the electric device connected to the power supply control unit 400 is on (switch closed state), the commercial power supply The power supply path between the electric devices becomes conductive. Accordingly, the light emitting element 86 operates to emit light, and the photodiode 88 detects the light and turns on.

Conversely, if the power switch 90 of the electric device is in the off state (switch open state), the power supply path between the commercial power supply and the electric device is non-conductive even when the switch section 80 is in the closed state. Become. Therefore, the light emitting element 86 does not operate, and the photodiode 88 does not operate.

DA on the anode side of the photodiode 88
Since the TA terminal is connected, when the photodiode 88 operates and the potential of the DATA terminal changes, this is transmitted to the terminal unit 200 via the DATA terminal. Therefore, the terminal unit 200 can detect, via the DATA terminal, conduction and non-conduction of the power supply path, that is, actual on / off of the electric device.

The detected ON / OFF state of the power supply of the electric equipment is transmitted from the terminal unit 200 connected to the power supply control unit 400 to the host unit 100, and the host unit 100 can know the power supply state of this electric equipment. . When the host unit 100 transmits a control signal to the terminal unit 200 according to the obtained power state, the terminal unit 200 outputs a control signal corresponding to the power control unit 84 of the power control unit 400. Therefore, conduction and non-conduction of the power supply path are controlled according to this control signal, and finally the power supply of the electric device to be managed is controlled. As described above, by providing the power supply control unit 400 with a configuration that detects conduction and non-conduction of the power supply path and transmits this to the terminal unit 200,
Through the terminal unit 200 and the power supply control unit 400, the host unit 100 can detect and control the power supply status of the non-system compatible electric equipment.

The power supply control unit 400 is not limited to the circuit configuration shown in FIG. 7, and controls the conduction and non-conduction of the power supply path between the commercial power supply and the electric equipment, and detects the condition. However, other circuit configurations can be adopted. Further, in the circuit configuration of FIG.
The switch unit 80 is controlled using the PC terminal of
The switch unit 80 based on a control signal from the DATA terminal
May be controlled.

[Identification and Registration of Terminal Unit] FIG. 8 shows a method of assigning an individual ID code to each terminal unit 200. The terminal unit 200 having a circuit configuration as shown in FIG.
When some or all of the buffer 38 and the communication unit) are integrated on the same circuit board and configured as one integrated circuit (LSI), the LSI and necessary elements are mounted on a circuit mounting board. You. At this time, the LSI is mounted on a circuit mounting board, and the LSI is mounted by wire bonding.
Are connected to the corresponding terminals on the circuit board.

In this system, individual IDs are assigned to each terminal unit LSI by utilizing this wire bonding process.
Attach the code. Specifically, as shown in FIG.
When connecting the terminal unit LSI to the circuit board,
Only the code setting terminal corresponding to the ID code assigned to each terminal unit 200 is bonded to the plurality of formed code setting terminals, and the remaining code setting terminals are left open (not connected). After the necessary LSI terminals are connected to the circuit board through these steps, each terminal unit LSI reads its ID code by accessing its own code setting terminal, and reads this ID code. It is used as an ID code assigned to itself.

For example, as shown in FIG. 8B, a p-type transistor Tr1 and a pull-up resistor are connected to a power supply, and an n-type transistor is connected to the ground. The transistor Tr2 is connected.
Also, all the wire-bonded terminals are connected to GND on the circuit board.

When reading the ID code, the transistor T
If r1 is turned on, "1" is read from a terminal that is not wire-bonded, and "0" is read from a terminal that is wire-bonded. The transistor Tr2 is unnecessary when reading the code from the code setting terminal and can be omitted. However, it is possible to prevent the potential of the terminal, particularly the potential of the terminal that is not wire-bonded, from becoming unstable. Therefore, as shown in FIG. 8B, it is preferable that this transistor Tr2 is connected between the code setting terminal and the ground, and is turned on except when the code is read.

It should be noted that the I set from the code setting terminal
The circuit configuration for reading the D code is not limited to the circuit configuration shown in FIG. 8B, but may be another configuration as long as the presence or absence of the wire bonding to the terminal can be detected.

By the way, as an ID code setting method,
In the wire bonding process for LSI terminals,
ID to terminal unit 200 depending on bonding
Instead of the method of assigning codes, a conventional method of setting a single code to an IC can be used. For example, ID code information may be stored in advance using an EEPROM or the like, or a switch may be provided on a circuit board to set the ID code by turning on and off the switch. Alternatively, after the wire bonding step, of the terminals on the circuit board connected to the terminals of the LSI, only the terminal corresponding to the ID code can be further connected by a jumper.

However, for example, when an EEPROM or the like is used or a switch is provided, the number of circuit elements increases by that much, and the method of connecting using a jumper requires a separate step of connecting a jumper after wire bending. , Leading to increased manufacturing costs. On the other hand, if the ID code is set together with the connection of the other terminals at the time of wire bonding as described above, the programming of the wire bonding apparatus can be set as desired, and the ID code can be automatically set without increasing the number of steps. Can be set. Therefore, the ID
It is possible to suppress an increase in the manufacturing cost of the terminal unit 200 due to the provision of the code.

Next, a method of registering the ID code of each terminal unit 200 in the host unit 100 will be described.
Registration of the ID code in the host unit 100 is performed by directly inserting the terminal 50 of the terminal unit 200 into the terminal unit insertion section 26 provided in the host unit 100 as shown in FIG.

The terminal unit 200 includes a communication unit and a microcomputer 30 and has the same configuration as that shown in FIG.
As shown in FIG. 2B, a terminal 50 for directly performing data communication with the system-compatible electric device or the power supply control unit 400 and the host unit 100 is provided. Terminal 50 is
As described above, the four-pole terminals VDD (CS), PC, D
It has ATA and GND. Depending on whether the terminal unit 200 has an internal power supply (battery), the VDD terminal and the CS
Although the terminals are interchanged, they have basically the same configuration.

Further, when the terminal unit 200 is connected to a system-compatible electric device, the PC terminal is simply used to keep the voltage level inside the terminal unit 200 constant. On the other hand, the power supply control unit 40 for the terminal unit 200 to control the non-system-compatible electric equipment.
When connected to 0, it is necessary to control the switch unit 80 arranged on the power supply path of the power control unit 400. Therefore, a control signal to the switch unit 80 is output from the PC terminal having a higher current supply capability than the DATA terminal,
The DATA terminal is used to detect conduction and non-conduction of the power supply path. However, the control signal may be output from the DATA terminal of the terminal unit 200 as in the case where the control signal is connected to a system-compatible electric device.

As shown in FIG. 9, the insertion unit 26 of the host unit 100 includes an interface circuit and the terminal unit 2.
00 terminals (VDDS, RR
Q, DATA, GND). Host unit 10
0 VDDS (VDD supply) terminal is the terminal unit 20
0 is a terminal for supplying the power supply VDD to the terminal unit 200 via a transistor when the internal power supply is not provided, and the GND terminal is set to the reference potential GND of the host unit. This is a terminal for matching the reference potential. Also, RRQ (regist req
est) terminal is connected to the terminal unit 200 by the host unit 1
It is a terminal for determining whether or not it is connected to 00. The DATA terminal of the host unit 100
When the terminal unit 200 is connected, its DATA
A terminal for performing asynchronous bidirectional serial communication for ID code registration with the terminal.

The procedure for registering the terminal unit 200 (ID code) in the host unit 100 will be described below with reference to FIG. First, the terminal unit 200 to be registered is connected to the host unit 100 as shown in FIG.
21). The microcomputer 12 of the host unit 100 communicates with the terminal unit 2 via the RRQ terminal shown in FIG.
It is determined whether or not 00 is connected (S1). When it is recognized that the connection is made, "terminal recognition" is notified to the terminal units 100 via the respective DATA terminals by asynchronous bidirectional serial communication (S2). Further, a request to start registration of the ID code is made to the terminal unit 200 (S
3).

The terminal unit 200 has an internal power supply (battery)
Is not provided, the system is started by receiving power supply from the host unit 100, and thereafter, the microcomputer 30 of the terminal unit 200 transmits the "terminal recognition" signal from the host unit 100, and the host unit 100 It is determined whether or not has been recognized (S2
2). If it is determined that the host unit 100 recognizes itself (S22, yes), the terminal unit 200
Determines whether an ID code registration start request has been made from the host unit 100 (S23).
If there is a registration start request (S23, yes), the terminal unit 200 transmits the ID code read from its own ID code setting terminal from its DATA terminal (S23).
24).

The host unit 100 is connected to the terminal unit 2
When the ID code from 00 is received (S4, yes),
The received ID code is registered in the EEPROM 18 in the unit 100 (S5). When the registration is completed, the host unit 100 notifies the terminal unit 200 of the completion of the registration (S6) and sends back the registered ID code.

The terminal unit 200 is connected to the host unit 1
It is determined whether registration completion has been reported from 00 (S2).
5) If there is a report (S25, yes), it is determined whether the transmission ID code returned next and the own ID code match (S26). If both ID codes match (S26, yes), the host unit 100
(S27), and if the two ID codes do not match (S26, No), a "terminal registration failure" is reported (S28).

The host unit 100 is connected to the terminal unit 2
Based on the report of the terminal registration success or failure from 00, it is determined whether the terminal registration is successful (S8), and if successful (S8, yes), a registration success message is displayed on the display panel (S9). In the case of failure (S8, N
o), a registration failure message is displayed on the display panel (S
10).

According to the above procedure, simply by connecting the terminal unit 200 to be registered to the host unit 100, the ID code of the terminal unit 200 can be automatically registered. After the registration is completed, the registered terminal unit 200 is connected to a power control unit 40 for controlling a desired system-compatible electric device or a non-system-compatible device.
Connect to 0. Thus, if wireless communication is performed between the host unit 100 and the terminal unit 200 using the ID code, a specific terminal unit 200 among the registered terminal units 200 can be arbitrarily selected without error, and the system-compatible electric device can be selected. Alternatively, it is possible to control a non-system-compatible electric device via the power supply control unit 400.
If the ID code is set to about 32 bits,
It is extremely unlikely that the codes match between the terminal units 200, and the terminal units 200 can be reliably identified.

As described above, by connecting the terminal unit 200 to the host unit 100 and automatically registering the ID code, the system user can check the ID code assigned to the terminal unit 200, and The troublesome work of registering the information in the 100 is not required, and erroneous registration can be reliably prevented. In addition,
The registration of the ID code of the terminal unit 200 does not necessarily require the terminal unit 200 to be directly connected to the host unit 100. Even if wireless communication is used based on a request from the host unit 100, a procedure similar to that of FIG. Thus, the ID code of the terminal unit 200 can be registered.

The type and management items of the system-compatible electric equipment to which the registered terminal unit 200 is connected, and the setting of the type of electric equipment connected via the power control unit 400 are, for example, the ID to the host unit. Following the code registration, the user presses the setting button 16a in FIG. 4 to shift to a desired setting mode, and displays and sets a menu on the display panel. Alternatively, after registering the ID code, the terminal unit 200 can be connected to the electric device or the power control unit 400, and then the setting can be performed by operating the setting button 16a of the host unit 100.

If it is determined in step S8 that the registration of the terminal unit has failed, the registration procedure shown in FIG. 11 is executed again until the registration succeeds, or the registration procedure is repeated a predetermined number of times. . Further, since the registration failure may be caused by a connection failure or failure of the terminal unit, in the case of registration failure, the ID code registration procedure of the terminal unit 200 is forcibly terminated without executing a retry. You may. In this case, the operator
The terminal unit 200 is replaced with the host unit 100, or the terminal unit 200 is discarded and a new terminal unit 200 is used. Here, in this system,
By making the terminal unit 200 as simple as possible, an inexpensive terminal unit 200 can be realized.
Therefore, even if the registration fails, the terminal unit 200
However, the economic burden on the system user can be reduced.

[Time Management] A centralized time management mechanism in the centralized management system according to the present embodiment will be described.
Currently, many electric devices have a built-in clock function and timer function, and each such device operates based on its own clock. However, at the time of new purchase or after a power outage, the time must be set by a different method for each device, and since the clock error differs for each device, adjustment is troublesome.

In this system, for example, the microcomputer 12 of the host unit 100 has a clock function and a timer function, so that each terminal unit 200 can be managed based on the clock and timer functions of the host unit 100. Become. The setting of the time in the host unit 100 is performed by, for example, pressing the setting button 16a to shift to the time setting mode and inputting the current time.

To set the timer, the user pushes the setting button 16a of the host unit 100 and shifts to the timer setting mode. Further, each of the electric devices or the power supply control unit 400 (terminal unit 200) for functioning the timer is selected using the scroll button 16c, and the timer operation time is set. Thus, when the set time is reached based on the clock of the host unit 100, the target terminal unit 200
, The host unit 100 instructs the start or stop of the operation by wireless communication. Therefore, a system-compatible electric device to which the terminal unit 200 is connected, or a non-system-compatible electric device connected to the power control unit 400 via the terminal unit 200 operates based on this command.

At present, except for television and audio equipment,
In many cases, the timer is cleared when the timer set time comes. It is troublesome work to go to the installation location of each electric device every day and individually set a timer, but in this system, using a single host unit 100,
Arbitrary timer times can be set for a plurality of electric devices by the same procedure, and timer setting work can be easily performed.

Regarding the electric equipment whose operation is to be started and stopped at the same time every day, even if the electric equipment has no function, it is connected to the system-compatible electric equipment or the power supply control unit 400 on the host unit 100. What is necessary is just to select the non-system compatible electric device (actually, select the corresponding terminal unit 200) and set so as to continue the timer function. Since the host unit 100 adopts a configuration in which a battery is incorporated, the clock of the host unit 100 does not stop even if a power failure occurs. All you have to do is reset the 100 clock,
There is no need to set the time for each electric device.

By setting the timer for the host unit 100 as described above, the air conditioner, the electric carpet, and the audio device in place of the alarm are operated at a predetermined time, for example, every morning based on the clock of the host unit 100. It is possible to control the electric rice cooker to operate at the time. Further, for example, if a certain period of time in the evening is managed such that the lighting equipment in the building is automatically turned on, it is possible to enhance the security effect when the user is away. Conversely, at a predetermined time, control such as stopping the operation of the air conditioner, the electric carpet, and the lighting equipment can be performed, so that it is possible to prevent forgetting to turn off the light, etc., thereby saving electricity and preventing fire. .

In this system, not only the timer function but also a function of automatically adjusting the built-in clock to an accurate time can be provided to the host unit 100. In this case, a time information receiving circuit may be provided in the host unit 100. Currently, radio broadcasting (440H
z, 880 Hz), for example, a time signal at noon is transmitted, and a standard radio wave JJY (5,
(8, 10 MHz).

The time information receiving circuit receives the time information from these broadcasts, and adjusts its own clock according to the received time information so that the clock in the host unit 100 can operate at the correct time. Can be. Since it is not necessary to constantly adjust the time, the time information receiving circuit is activated once or several times a day at a predetermined time, for example, based on a clock in the host unit 100, and based on the obtained time information. It is only necessary to adjust the time of the clock.

When the system-compatible electric equipment has an extended function that can be specially managed by the centralized management system, the accurate time information obtained by the time information receiving circuit is transmitted to the terminal unit 200 via the terminal unit 200. Wireless communication may be performed with the device. Thus, each electric device having the extended function can adjust its own built-in clock based on the obtained time information.

[Power Supply Batch Control] In this system, since the electric devices are centrally managed, it is also possible to cut off the power supplies of a plurality of electric devices collectively. Currently, electric stoves and the like are often equipped with earthquake countermeasures, but not all electric stoves and all electrical devices are equipped with earthquake countermeasures. Therefore, when a disaster such as an earthquake occurs, it is necessary to immediately turn off the power of an electric device that may generate heat or ignite before evacuation. However, since a large number of electrical devices are used in one home, it takes time to surely turn off the power of all the electrical devices one by one.

Further, since the power supply within the management range is controlled by the breaker, the power supply within the management range can be collectively turned off by the breaker. However, this breaker is not automatically turned off unless there is a short circuit or a short circuit, and is often set in a place where it is hard to reach and few people go.
Therefore, there is a case where it is not possible to evacuate by turning off the breaker when a disaster occurs.

Accordingly, in the present system, as shown in FIG. 4, the host unit 100 is provided with a power-off button 16b as an operation button. When the button 16b is pressed, the host unit 100 immediately transmits the signals to the terminal units 200 connected to the target system-compatible electric device and the terminal units 200 connected to the power control unit 400 for controlling the non-system-compatible electric device. , And automatically transmits a control signal for instructing a power-off of the electric device. Thus, it is possible to control the power supply of necessary electric devices to be turned off collectively by simply pressing the operation button of the host unit 100.

The electrical devices to be turned off by the batch off button 16b can be set in the host unit 100 in advance. For example, as shown in FIG. 12, for electric appliances such as an electric rice cooker, a kotatsu, an oven, and an electric stove, which are likely to generate heat or fire at the time of disaster,
By setting as a device to be controlled by the collective off button 16b, it is possible to turn off necessary electric devices. In addition, it is also possible to set so that the power supply control units 400 that control all the system-compliant electric devices and the non-system-compliant electric devices registered in the host unit 100 are collectively turned off via the corresponding terminal units 200.

Further, when the ID code of the terminal unit 200 is registered, the type of the electric device (for example, a heating device such as an electric stove, an electric carpet, and an electric blanket) associated with the terminal unit 200 is registered. Can also. If such registration is made, the batch off button 16b
When the button is pressed, the host unit 100 may automatically select a type of device that needs to be controlled from the registered types of electrical devices and perform off-control.

Since the host unit 100 can be configured to be portable, if it is always kept at hand, for example,
Even if an earthquake occurs when you cannot release your hand or cannot operate immediately, such as when you are preparing a meal at the kitchen or sleeping, you can use the batch off button 16 of the host unit 100 at hand.
By pressing b, it is possible to immediately turn off the power of not only nearby electric devices but also electric devices in a remote room. For this reason, forgetting to erase some of the devices can be reliably prevented.

When the batch off button 16b is pressed, a configuration in which the timer function which is automatically operated every day is cleared is also applicable. In the case of evacuation due to a disaster or the like, it is conceivable that the timer function of the host unit 100, which is used on a daily basis, operates in an unmanned building after the evacuation to operate the electric equipment. When the batch off button 16b is used, such a problem can be avoided by clearing the timer function for all devices.

Further, while the power supply of necessary electric equipment is controlled to be turned off at the time of a disaster or the like, for example, in order to facilitate evacuation, for the electric equipment such as lighting equipment, the collective off button 1 is used.
When the user presses the button 6b, the host unit 100 can automatically turn on the corresponding electric device by wireless communication.

The above-described batch-off function can be used not only at the time of a disaster but also at the time of going out, etc., so that the power supply of necessary electric equipment can be batch-turned-off. With this function, forgetting to turn off can be reliably prevented, and the trouble of confirming the power on / off of each electric device can be omitted. An operation button dedicated to going out may be separately prepared. In a configuration in which the above-described timer function is automatically cleared when the batch off button 16b is pressed, it is preferable to provide another operation unit dedicated to going out.

Next, a description will be given of a system for automatically detecting an earthquake and executing a collective power cut-off of a target electric device. When an earthquake occurs, human
In some cases, the 00 batch off button 16b cannot be pressed. Even in such a case, if the system is configured to automatically and automatically shut off the power of the electric device, a secondary disaster such as a fire caused by the electric device can be prevented.

This system can be realized by, for example, installing a vibration sensor 60 having a wireless communication function as shown in FIG. The vibration sensor 60 is a sensor that notifies the host unit 100 by wireless communication when a vibration exceeding a predetermined level is detected. However, the terminal unit 200 can be connected to the vibration sensor 60 in the same manner as other electric devices, and the communication between the connected terminal unit 200 and the host unit 100 detects the vibration of the vibration sensor 60 by the host unit. A configuration for notifying 100 may be employed.

The operation procedure will be described below with reference to FIG. When the vibration sensor 60 detects vibration having a predetermined strength or more (S31, yes), a vibration detection report is wirelessly transmitted to the host unit 100 (S32).
The host unit 100 receives the vibration detection report (S33), and in that case (S33, yes), the host unit 100 automatically sends the terminal unit 200 connected to various electric devices or the power supply control unit 400 as shown in FIG. Then, "power off" is transmitted together with the ID code. In addition, in order to prevent confusion at the time of evacuation, power-on, that is, "lighting-on" is transmitted to the terminal unit 200 connected to the lighting equipment together with the ID code (S34). If the lighting device is not compatible with the system, the terminal unit 20 corresponding to the power control unit 400 to which the lighting device is connected.
A signal for turning on the lighting device is transmitted to 0.

When each terminal unit 200 receives the control signal from the host unit 100 (S35, S4
0), it is determined whether or not the ID code assigned to the control signal matches the ID code of its own terminal unit 200 (S36, S41).

If the ID codes match and the control signal is a power-off control of the connected electrical equipment (S36, yes)
s) The power of the system-compatible electric device is turned off by outputting a power-off signal from the DATA terminal of the terminal 50, and the power of the system-non-compatible electric device is turned off via the power control unit 400.

If the ID codes match and the control signal is power-on control of the connected electrical equipment (S41, yes
s), a power-on signal is output from the DATA terminal of the terminal 50 to turn on the system-compatible electric device, that is, to turn on the lighting device,
Turn off the power of the lighting equipment not compatible with the system via.

If the ID codes do not match (S3
6, no or S41, no), the terminal unit 200 does not operate, and the corresponding electric device is not controlled.

After executing the power off / on control for the above-mentioned system-compatible and system-non-compliant electric devices, the terminal unit 200 determines whether or not those electric devices are actually in the off or on state by checking the DATA terminal. Judgment is made from the obtained signal (S38, S43). If the power-off of the electric device has been completed based on the power-off control (S
38, yes), the power-off completion is transmitted to the host unit 100 (S39). If the power-on of the electric device (lighting of the lighting device) is completed based on the power-on control (S43, yes), a power-on completion is transmitted to the host unit 100 (S44).

The host unit 100 monitors whether or not there is an operation completion report from each terminal unit 200 (S45). When the operation completion report is received (S45, yes)
s) It is determined whether or not the operations of all the terminal units 200 that have ordered the operations have been completed (S46). Then, when the operation of all the terminal units 200 that ordered the operation is completed (S46, yes), the host unit 100 displays the completion of the operation on the display panel 10 (S4).
7), complete the power supply collective management work.

Note that the lighting equipment whose power is controlled to be turned on can be automatically turned off after a lapse of a predetermined period from lighting by, for example, activating a timer function of the host unit 100. In the procedure shown in FIG. 14, the lighting device is turned on in the event of an earthquake, but it is not necessary to turn on the lighting device. In that case, only the necessary power-off control of the electric device is executed.

Here, when the host unit 100 receives the vibration detection direction from the vibration sensor 60, the host unit 100 executes the above-described predetermined control for each terminal unit 200 and also notifies the person of the earthquake. A warning sound can be generated from a built-in speaker, and a warning lamp can be turned on (see FIG. 4).

With such a system, for example, in a state where the hand cannot be released in the event of an earthquake, when there is no person, or when evacuation is not possible after turning off the power of the electric equipment at the time of evacuation. Even so, it is possible to automatically detect the earthquake and turn off the power of necessary electrical equipment, so that secondary disasters can be avoided reliably.

In the above description, an earthquake is sensed by the vibration sensor 60 and the electrical equipment is controlled collectively. However, the present invention is not limited to the earthquake. For example, if a smoke sensor or a heat sensor is provided in addition to the vibration sensor 60 shown in FIG. It is also possible to prevent the spread of fire. That is, when smoke detection or heat detection is notified from these sensors, it is determined that a "fire" has occurred, and a warning lamp is turned on, a warning sound is generated, and evacuation is prompted.
According to the same procedure as described above, the host unit 100 collectively turns off the power of necessary electric devices such as heating devices. In addition, control such as turning on a light for a certain period may be performed to facilitate evacuation.

[Criminal Security System Function] In the above-described centralized management system according to the present embodiment, by further using an impact sensor, an infrared sensor, and the like, the present system can be provided with a security system function. The system configuration may be such that, in FIG. 13, the vibration sensor 60 is replaced with an impact sensor, and this impact sensor is provided, for example, on a door or a window. When the impact sensor detects that an impact of a predetermined level or more is applied to a door or a window, the impact sensor outputs an impact detection signal to the host unit 1.
Tell 00. Based on the shock detection signal, the host unit 100 generates a warning sound from a built-in speaker and turns on a warning lamp in order to notify a person that a shock has been applied (see FIG. 3). The host unit 100 is also provided with a terminal unit 200 provided in the lighting device to turn on a predetermined lighting device that has been set.
, An illumination ON signal is transmitted together with the ID code. Thereby, the corresponding lighting device can be turned on. If the lighting equipment does not support the system,
By controlling the power supply control unit 400 to which the lighting device is connected via the terminal unit 200, the lighting device can be turned on.

According to such a system, when there is an intruder from a door or a window, this is automatically and promptly notified to a person in the building, and the lighting is turned on to scare the intruder. Becomes possible. If an alarm is provided separately for the centralized management system, the host unit 100 may operate the alarm through the terminal unit 200 to sound an alarm based on the shock detection signal. Can be. As described above, when an impact is applied to a door or a window by an intruder, the illumination is immediately turned on and an alarm is sounded, so that a higher intrusion suppression effect can be obtained.

Further, when an infrared sensor is installed, for example, under a window, in a garden, at a front entrance, or the like, and when the movement of a person is detected, the host unit 100 receives a notification from the infrared sensor and operates via the terminal unit 200 via the terminal unit 200. By activating indoor lighting equipment and lighting equipment at the entrance and sounding an alarm, the intrusion of a suspicious person can be suppressed. Conversely, when there is a visitor, the illumination can be automatically turned on, and a chime can be sounded in the building, or a sound can be output from the speaker of the host unit 100 to perform the intercom function.

Further, the system is not limited to the configuration shown in FIG. 1 in which the host unit 100 for centrally managing other electric devices receives detection signals from these shock sensors and infrared sensors and operates. As shown in FIG. 15, a dedicated host unit 101 having a built-in impact sensor 62 may be separately prepared to perform an action such as turning on a predetermined illumination.

In the case of the configuration shown in FIG. 15, the ID code of the terminal unit 200 corresponding to the electric device to be operated when a predetermined impact or motion is detected is registered in the dedicated host unit 101 in advance. . When the shock sensor 62 of the dedicated host unit 101 detects a shock, an operation command is given from the dedicated host unit 101 to necessary electric equipment (such as a lighting fixture) via the terminal unit 200. If the target electrical device is not compatible with the system, the power supply control unit 400 is controlled via the terminal unit 200, and thereby the electrical device is operated.

As shown in FIG. 15, if a dedicated host unit 101 is used for crime prevention, the host unit 100 shown in FIG.
Processing load can be reduced. Therefore, an inexpensive host unit 1 that is portable, has fast processing, and has few items to be processed.
By providing the dedicated host unit 101 while providing the security system 00, it is possible to add a security system function. Also, instead of controlling the terminal unit 200 directly from the dedicated host unit 101, the dedicated host unit 1
It is also possible to adopt a configuration in which the host unit 100 is once notified of the impact detection from 01, and a predetermined lighting device or the like is turned on by the host unit 100.

Further, the impact sensor 62 does not necessarily need to be built in the dedicated host unit 101, and the terminal unit 200 can be inserted like other electric equipment, and the host unit 100 or 101 can be inserted through the terminal unit 200.
May be configured to transmit the impact detection.

[Power Saving System] The above-described system can be functioned to save power. FIG.
As shown in FIG. 1, for example, an air conditioner, a television, and a lighting device are placed in a room. Among them, the terminal unit 200 is attached to the system-compatible electric device, and the power supply control unit 400 (not shown) ), And the terminal unit 200 is attached to the power control unit 400. Then, the host unit 300 as shown in FIG. 16 is installed on a wall or ceiling of the room. This host unit 300 has the configuration shown in FIG.
As shown in FIG. 7, a sensor 64 such as a pyroelectric sensor, a motion sensor, or a human body sensor is built in, and the ID code of the terminal unit 200 to be controlled in the room is registered in the EEPROM.

The host unit 300 detects whether or not there is a person in the room by using the sensor 64, and FIG.
When the sensor 64 detects the movement of a person when the person is in the room, the host unit 300 sends a signal to the registered terminal unit 200 to turn on the electric device. Each electric device corresponding to the terminal unit 200 maintains the on state when the electric device is already in the on state.

As shown in FIG. 16 (b), when the person is no longer in the room and the movement of the person is not detected by the sensor 64 for a predetermined period (for example, 15 minutes), the microcomputer 12 sends the registered terminal unit 200 On the other hand, a signal for turning off the power of the device is wirelessly transmitted. The terminal unit 200 receives this signal, and the power of the corresponding device is turned off.

According to such control, when there are no more people, unnecessary electric devices can be automatically turned off. Therefore, it is possible to prevent wasteful consumption of electricity due to forgetting to turn off, and to prevent occurrence of fire due to forgetting to turn off.
On the other hand, as soon as a person enters the room, the sensor 6
4 detects this and turns on the registered electric device, so that the electric device is not turned off when necessary, and can also function as a security system.

In the above description, the host unit 300 containing the sensor is mounted in the room, and the host unit 300 controls the terminal unit 200.
However, it is not limited to such a configuration. For example, a sensor having a wireless communication function or a sensor equipped with a terminal unit 200 is installed in a room, and the detection result of the sensor is used to transmit a host unit 10 common to the building shown in FIG.
0 may be transmitted. In this case, the host unit 1
00 transmits a control signal based on the detection result of the sensor 64 to a predetermined terminal unit 200 to be controlled in the room where the sensor is installed. According to such a method, the power of unnecessary electric devices can be controlled to be turned off as described above, and the power can be turned on immediately after detecting the movement of a person, which can also be useful for crime prevention.

[Others] In the above description, a plurality of electric devices (terminal unit 2
00), the configuration of centralized management is taken as an example, but a plurality of host units 100 may be provided. The plurality of host units 100 can also limit the functions of the host unit 100 corresponding to the slave units, for example, in the relationship between the master unit and the slave units of the telephone. Conversely, exactly the same function and authority may be given.

When there are a plurality of host units 100, the operation of registering the ID code of the terminal unit 200 in each host unit 100 must be executed separately. That is, in order to control the same terminal unit 200 by a plurality of host units 100, each host unit 100
As described above, the terminal unit 200 is directly inserted to perform ID code registration work. However, if an ID code already registered in a predetermined host unit 100 can be copied to another unregistered host unit 100 by wireless communication or the like, duplicate ID code registration work can be omitted.

It is preferable that the host unit 100 has a built-in power supply and is portable in consideration of its operability. In addition, if a plurality of host units 100 are provided, for example, one is placed in a predetermined place and the rest is carried by an operator, it is very easy to use and practical.

The control authority of a plurality of host units 100 for the same terminal unit 200 is the same unless otherwise specified. If commands for the same terminal unit 200 overlap, the terminal unit 200 will be updated to the latest control command. It operates based on the above, and the transmission signal from the terminal unit 200 is received by each of the host units 100 in which the unit 200 is registered.

As described above, when a disaster occurs, an operation of pressing the batch off button 16b of the host unit 100 is performed. In addition, even if the system is away from the house where the system is installed, if the distance is, for example, about 30 m to 100 m, it is possible to execute off control of the electric device from outside the house. There is also the possibility of evacuating. Therefore, if the host unit 100 used in such an emergency is provided with a lighting function and a radio receiving function, for example, the operation of the host unit 100 at the time of a nighttime disaster becomes easy, and the evacuation route can be illuminated. This makes it possible to know the disaster situation. Therefore, a more convenient and functional system can be provided as a disaster prevention measure.

The device central management device controls each electric device via the terminal device. Further, a device power control device is interposed between the electric device and the terminal device for managed device.

[Power Supply Batch Control] In this system, since the electric devices are centrally managed, it is also possible to cut off the power supplies of a plurality of electric devices collectively. Currently, electric stoves and the like are often equipped with earthquake countermeasures, but not all electric stoves and all electrical devices are equipped with earthquake countermeasures. Therefore, when a disaster such as an earthquake occurs, it is necessary to immediately turn off the power of an electric device that may generate heat or ignite before evacuation.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for centrally managing a plurality of electric devices including different types, for example, lighting devices, air conditioners, televisions, and the like by wireless communication.

[0002]

2. Description of the Related Art With the spread of various convenient and inexpensive electric appliances, heating appliances such as air conditioners and electric stoves, various cooking appliances, televisions, cassette recorders with radios, and video devices are now being used in homes and offices. Audio-visual equipment such as
Many electric devices are arranged and used. But,
Naturally, many of these electrical devices are basically controlled individually.Even if a remote controller is provided, go to the place where each device is located and use a dedicated controller. You have to control. And as the number of electrical devices increases, for example, it takes a lot of time to turn on the power of each device, set an operation timer, and cut off the power supply to each electrical device when unnecessary, The number of remote controllers also increases.

Under such circumstances, proposals for a home automation system for centrally managing many electric devices have been started.

On the other hand, various sensors are installed inside and outside the building for security monitoring at home or office,
A security system has been realized that remotely manages smoke and flame detectors, intruder detection, and the like.

[0005]

However, in a normal centralized management system, control signals are directly exchanged between the electrical equipment to be controlled and the centralized management device. Circuit must be provided. For this reason, in order to make electrical equipment compatible with the system, it is necessary to change the design of general-purpose electrical equipment, and furthermore, equipment dedicated to the system requires the above-mentioned dedicated circuit, which increases the cost of the equipment. Unavoidable.

[0006] On the other hand, there are cases where the purchaser of the electric equipment does not want to install the system and only wants the original functions of the electric equipment, or when he has already introduced a different type of system. is assumed. In such a case, the purchaser does not need a special function for system compatibility of electrical equipment, and because it is compatible with the system,
Highly priced electrical equipment may not be attractive.

[0007] Further, if it is necessary to replace all existing non-system-compatible electrical equipment with system-compatible electrical equipment in order to introduce a centralized management system, that is, if it is necessary to replace the electrical equipment, economical burden for introducing the system is required. Is very large, and there is a problem that the system is difficult to spread.

On the other hand, if only electrical equipment compatible with the system can be managed, only a small-scale system can be constructed, and the centralized management system cannot be effective.

[0009] Furthermore, in the above-mentioned security system and the like, large-scale construction such as installation work for sensors and communication devices and wiring work is required when introducing the system, and the introduction cost itself is often high. .
Therefore, introduction of the system is not considered unless the building is newly constructed. Therefore, also in this case, it is difficult to increase the system penetration rate.

In order to solve the above-mentioned problems, according to the present invention, a centralized management system for devices is low in cost and easy to introduce. Further, not only system-compatible electric devices but also non-system-compatible electric devices can be managed. The aim is to provide a possible management system.

[0011]

To achieve the above object, the present invention has the following features.

The present invention relates to a system for centrally managing a plurality of electric devices, comprising: a centralized device for managing target electric devices by a wireless communication function; A terminal device for a managed device that outputs a predetermined device control signal based on wireless communication with the device central management device for the electrical device, and further, the managed device terminal device and the management target. An electrical power control device that is interposed between the electrical devices to be managed, receives the device control signal from the managed device terminal device, and controls operation power supply to the electrical device to be managed. It is a feature.

The present invention also relates to a device power control device, which is used in a system for centrally managing a plurality of electric devices by a device centralized management device via a terminal device for managed devices. Outputting a predetermined device control signal for controlling the electrical device to be managed based on wireless communication between the electrical device to be managed and the device centralized management device registered in the device centralized management device Interposed between the managed device terminal device and the device control signal from the managed device terminal device, and controls the operation power supply to the managed electrical device. Is what you do.

As described above, in the system of the present invention, wireless communication is performed only between the device central management device and the terminal device for managed device registered in the device. Therefore, a wireless transmission / reception mechanism is not required for each electric device to be managed, and the production cost of the electric device at the time of introducing the system can be kept very low even if there is no increase.
Further, in the present invention, the device power supply control device is interposed between the managed device terminal device and the electric device. Therefore, even if the electrical device to be managed has a configuration that does not support the system, the device power control device supplies the operating power to the device that does not support the system in response to the control command from the managed device terminal device. By performing the control, the operation of the electric device can be substantially controlled from the device central management device.

Further, in the present invention, the device power supply device includes:
A switch unit that switches between conduction and non-conduction of a power supply path between a predetermined operation power supply and the electric device to be managed; a switch control unit that controls the switch unit; A detection unit for detecting a conduction state;
Comprising, according to the device control signal from the terminal device for managed device correspondingly arranged, the switch control unit controls the switch unit, conduction of the power supply path,
Non-conduction is controlled, and the conduction or non-conduction state of the power supply path detected by the detection unit is transmitted to the corresponding managed equipment terminal device.

As described above, when the device power supply device not only controls the conduction and non-conduction of the power supply path between the operating power supply and the electric device but also detects the conduction and non-conduction state, the device is to be managed. The operating state of the electric device can be detected almost certainly. The fact that the power supply path is non-conductive means that the power supply between the operating power supply and the electric equipment is controlled by the switch unit controlling the supply path to be non-conductive or by turning off the switch of the electric equipment body. Indicates that the supply route is broken. The fact that the power supply path is in the conductive state means that the switch unit controls the conduction of the power supply path, and that the switch of the electric apparatus main body is turned on, so that the power supply path between the operation power supply and the electric apparatus is turned on. Indicates that is conducting. Therefore, if the conduction / non-conduction state of the power supply path is detected, this is transmitted to the centralized management device via the terminal device for the managed device, and the centralized management device is turned on / off of the electric device. That is, it is possible to know the on / off state of the operation and manage the state.

The present invention also relates to a system for centrally managing a plurality of electric devices, comprising a device centralized management device for managing a target electric device by a wireless communication function, and a device registered and managed in the device centralized management device. A managed device terminal device for outputting a predetermined device control signal to a target electrical device based on wireless communication with the device centralized management device, and further, the managed device terminal device and the management device Interposed between the target electrical device, receiving the device control signal from the managed device terminal device, a device power control device that controls the operation power supply to the managed electrical device,
Comprising, the managed device terminal device connected to a system-compatible electrical device, the device centralized management device, the system-compatible electrical device via the managed device terminal device connected to the device Managing, connecting the device power control device to the system-incompatible electrical device, connecting the managed device terminal device to the device power control device, and controlling the device centralized management device to operate the system-incompatible electrical device. Are managed via the device power control device connected to the device and the managed device terminal device connected to the device power control device.

Regarding the electric equipment corresponding to the system,
By associating the above-mentioned terminal device for a managed device by connecting or the like, this device can be controlled by the terminal device for a managed device. In addition, the device power control device can be controlled by the managed device terminal device by associating the managed device terminal device with the device power control device in the same manner as other system compatible electrical devices by connecting the managed device terminal device or the like. Accordingly, the management system by the centralized management device can be arbitrarily assigned to both the system-compatible electrical device and the system-incompatible electrical device by directly associating the managed device terminal device or indirectly via the device power control device. Can be incorporated into Therefore, the user can construct any centralized management system at his own will.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention (hereinafter, referred to as embodiments) will be described below with reference to the drawings.

[System Configuration] FIG. 1 conceptually shows the configuration of a centralized device management system according to an embodiment of the present invention. In this centralized management system, a device centralized management device (hereinafter, referred to as a host unit) 100 has a function of a host computer for centrally managing electrical devices. The managed devices managed by the host unit 100 include, for example, home electric appliances such as electric rice cookers and irons, various electric devices that are used daily in homes or offices, such as televisions, videos, cassette decks with radios, and the like. is there. Further, in the present system, the electric devices are not limited to the devices whose power sources are all electric power, and operate by power other than electric power, such as an oil fan stove, but the control of the devices is performed electrically. Centralized control is also possible for controlled devices.

In the present system, a small terminal device for a managed device (hereinafter, referred to as a terminal unit) 200 is interposed between the corresponding electric device and the host unit 100 separately from the electric devices to be managed. . Each electrical device corresponding to the present system is provided with a receptacle (terminal insertion section) to which the terminal unit 200 can be connected. By inserting the terminal unit 200 into this receptacle, the host unit 100 is inserted. Via the terminal unit 200, the power supply of the electric device and other functions are controlled.

However, there are cases where the electric equipment to be managed does not correspond to the system. If the terminal unit 200 cannot be mounted on the electric device, the electric device cannot be controlled via the terminal unit 200.

Therefore, in the system according to the present embodiment,
Even if the electric device does not support the system, the electric device can be controlled via the terminal unit 200. The control of the electric equipment which is not compatible with the system is performed by a power control unit 400 which directly controls the supply of the commercial electric power which is the operation power supply to the electric equipment between the electric equipment and the terminal unit 200.
Is realized by interposing

The power supply control unit 400 has a terminal plug-in unit, and the same terminal unit 200 as the terminal unit 200 mounted on the system-compatible electric equipment can be mounted on this terminal plug-in unit. Then, as shown in FIG. 2, the power supply control unit 400 converts the power supplied from the commercial power supply into the A of the electric device.
C, a supply path to be supplied to the power outlet, a switch unit (here, a relay) 80 provided in the supply path for switching the supply path on and off, and a switch unit in accordance with a control signal from the terminal unit 200 mounted. The power supply control unit 82 controls opening and closing of the power supply 80.

The power supply control unit 400 has the terminal unit 2
When the terminal unit 200 receives a control signal from the host unit 100, the corresponding control data is transmitted from the terminal unit 200 to the power supply control unit 40.
Informed to 0. Therefore, the power supply control unit 400 controls the opening and closing of the switch unit 80 according to the data to directly control the supply of the commercial power to the electric device.

By using the power supply control unit 400 as described above, even if a plurality of electrical devices that are to be centrally managed do not correspond to the system, the power supply control unit 400 can be controlled via the terminal unit 200. Thus, it is possible to control the power supply of the electric equipment that is not compatible with the system from the host unit 100 side.

Each terminal unit 200 and host unit 1
The communication with 00 is performed by setting both units as local radio stations.
For example, digital wireless communication using a band (specific low power) of about 230 to 240 MHz or 400 MHz is performed. However, if the control is performed within a narrow range, wireless communication by a weak wireless station, infrared communication, and the like are also possible. By adopting wireless communication, even if this system is introduced, each electric device can be controlled by the wireless communication between the host unit 100 and the terminal unit 200 and the power supply control unit 400 when the system is not compatible. There is no need to perform wiring work, etc.

As will be described later, an individual 32-bit unique code (hereinafter referred to as an ID code) is allocated to each terminal unit 200 at the time of manufacture, as will be described later, and the host unit 100 identifies each terminal unit 200 by its ID code and controls it. I do. The ID code of the terminal unit 200 can be registered in the host unit 100. After registering the ID code, the terminal unit 200 is inserted into the system-compatible electric device among the devices desired to be incorporated into the centralized management system. In the case of a non-system compatible electric device, the power plug of the electric device is inserted into the power control unit 400, and the terminal unit 200 is inserted into the power control unit 400. As a result, the device is managed by the host unit 100 via the terminal unit 200 in the case of a system compatible device, and is managed by the host unit 100 via the power supply control unit 400 and the terminal unit 200 in the case of a system non-compliant device. Note that wireless communication between the host unit 100 and the terminal unit 200 is preferably performed using, for example, spread spectrum communication or the like in order to prevent malfunction of other electronic devices.

The ID code of the host unit 100
The terminal unit 200 registered in is registered in the electric device or the power supply control unit 400, and is always in a state where a transmission signal from the host unit 100 can be received. The terminal unit 200 is connected to the host unit 1
When a control signal with its own ID code is received from 00, the control signal is recognized as a control signal for itself and control of the corresponding electric device or control of the switch unit 80 of the power supply control unit 400 is performed. When the control is executed, a completion report or the like is transmitted to the host unit 100.

Even if the host unit 100 transmits a control signal to a specific terminal unit 200, if there is no response from the terminal unit side, the transmission is executed several times. If there is still no response from the terminal after executing the retry, the host unit 100 issues a warning message such as "No response" or "Unable to transmit" as a warning message for the electrical device corresponding to the ID code. To be displayed.

Further, the terminal unit 200 automatically
Alternatively, in response to a request from the host unit 100, the state of the corresponding electric device (for example, the power on / off state) is reported to the host unit 100. Power control unit 400
Although the terminal unit 200 connected to the power control unit 40 cannot directly know the state of the electric device,
0 of the switch unit 80 of the host unit 100
Report to

The host unit 100 stores the obtained status of each device, and displays the stored status when the system user selects the device. For example, when “illumination in a child's room” is selected by the host unit 100, if the power status reported so far is illumination on, “illumination on” is displayed. When "living air conditioner" is selected, for example, if the reported state is off, "air conditioner off" is displayed. Alternatively, when a “door closing” is selected in the host unit 100 by using a door closing sensor or the like as an electric device or using a sensor with a terminal function, for example, “kitchen entrance entrance item” is displayed.

From the power supply control unit 400 to the switch unit 8
When the open / close state of 0 is obtained, the host unit 100
For example, when the switch unit 80 is open and the power supply to the electric device is off, “unit off” is displayed. When the switch unit 80 is closed and the power supply to the electric device is on, “unit off” is displayed. "ON" or the like is displayed on the display panel 10.

When the switch section 80 of the power supply control unit 400 is controlled to open, if the power supply path between the commercial power supply and the electric equipment is non-conductive, no operation power is supplied, and the electric equipment is turned off. doing. On the other hand, if the switch unit 80 is controlled to be closed, the power supply path is conductive, so that the operation power is supplied, and the electric device is on unless the power is turned off on the electric device main body side. Therefore, the open state and the closed state of the switch unit 80 of the power supply control unit 400 can be regarded as the off and on states of the electric device, respectively. Therefore, the host unit 100 converts the open / closed state obtained from the power control unit 400 via the terminal unit 200 into the power control unit 4.
It is also possible to consider that the device connected to 00 is off and on, and to display “XX device off”, “XX device on”, and the like.

As described above, through the terminal unit 200 or the power supply control unit 400 and the terminal unit 20
If the status of the electrical device to be managed is reported to the host unit 100 via the “0”, the system user can know the status of the electrical device to be managed from the display panel 10 of the host unit 100. Further, depending on the state, even if each device is located in another place, the host unit 100 can issue an appropriate control command. However, when the open / close state of the switch unit 80 in the power control unit 400 cannot be directly detected, the switch on / off control signal supplied to the switch unit 80 may be displayed as the open / close state of the switch unit 80. Good.

A setting button 16a for shifting to a setting mode such as the presence / absence of audio output, a collective off button 16b for collectively turning off power to the electric devices to be managed, a scroll button 16c for selecting a plurality of items, Various buttons are provided as needed, such as a character input button 16d for inputting and an input mode button 16e for selecting an input character type (kana, English).

The communication unit of the host unit 100 includes a wireless transmission / reception unit 20 for transmitting and receiving wireless communication with the terminal unit 200, a filter 22, and an antenna 24. The LCD driver 14 is a driver for driving the LCD display panel 10 using a matrix type or partially segmented electrodes. The EEPROM 18 is a storage unit that stores the above-described ID codes of the terminal units 200 and the settings for centralized management, and registers the read ID codes of the terminal units 200. The microcomputer 12 is a centralized control unit, and includes a wireless transmission / reception unit 20, an LCD driver 14, an operation unit 16, and an EEPROM.
While managing the M18, the terminal unit insertion section 26, etc.,
Each terminal unit 2 by wireless communication via the antenna 24
00 is managed.

Next, the configuration of the terminal unit 200 will be described. 5 and 6 show a schematic configuration of the terminal unit 200. The terminal unit 200 includes a wireless transmission / reception unit 32, a filter 34, and a built-in antenna 36 as a communication unit for performing wireless communication with the host unit 100. Also, the overall operation of the terminal unit 200 is managed,
The microcomputer 30 generates a signal for controlling the connected electric device or the power supply control unit 400, and detects a state of the electric device and generates a signal for notifying the host unit 100. Further, it has a buffer 38 for temporarily storing data to be transmitted and received.

The terminal 50 of the terminal unit 200 is composed of two plug-in terminals,
Can be inserted into the terminal insertion section 40 provided in the terminal.
The two insertion terminals are electrically separated into two by an insulating separation portion 51, respectively, and the terminal 50 is constituted by a four-pole terminal. When the internal power supply is not provided in the terminal unit 200, the GND terminal 52, the DATA terminal 54,
PC (power control) terminal 56, VDD terminal 58
It has pole terminals. When the terminal unit 200 has an internal power supply, CS (connect
sense) terminal, and the CS terminal detects whether the terminal unit 200 is connected to the electric device or the power supply control unit 400.

The terminal unit 200 provided in the electric equipment and power supply control unit 400 has the terminal unit 200
Terminal (VDDS (VDD Supp
ly) terminal, PC terminal, DATA terminal, GND terminal). When the terminal unit 200 is inserted into the terminal end insertion part 40 of the electric device or the power supply control unit 400, if there is no built-in power supply, first, the V
The device is activated by receiving power supply from an electric device via the DD terminal 58. Thereafter, the terminal unit 200 transmits the DATA
From the terminal, the power status of the electric device and the power control unit 400
Of the power supply path is detected. Then, the detection result is voluntarily reported as described above or in response to a status report request from the host unit 100, and the power ON / OFF state of the detected device is reported together with its own ID code. The terminal unit 200 is connected to the host unit 10.
When a control signal from 0 is received, a device control signal corresponding to the control signal is sent to the electric device via the DATA terminal 54. Also, a control signal may be sent to the power control unit 400 using a PC terminal, as described later. As a result of the control, on / off of the power of the system-compatible electric device is controlled, and conduction and non-conduction of the power supply path by the power control unit 400 are controlled for the non-system-compatible electric device. Note that the terminal unit 200 may transmit the control signal transmitted from the host unit 100 as it is to the electric device or the power control unit 400 as a device control signal.

In the case where the system-compatible electric equipment has an extended function capable of further managing special items by the centralized management system, the terminal unit 200 mounted on the electric equipment is connected to the DATA terminal 54 via its DATA terminal 54. The presence or absence of the extended function of the device is automatically detected and sent to the host unit 100 together with the contents of the function.

[Detection of State of Electrical Equipment by Power Control Unit] In the configuration of FIG. 2, the terminal unit 200 connected to the power control unit 400 is a switch provided on a path from a commercial power supply to a non-system compatible electrical equipment. Part 8
It only detects opening and closing of 0, and cannot directly detect the power state of the electric device. Power control unit 400
When the switch unit 80 is open, the electric device is turned off because the power supply from the commercial power supply is cut off, and the open state of the switch unit 80 corresponds to the off state of the electric device. However, when the switch unit 80 is in the closed state and the power switch of the electric device main body is turned off (switch open), the electric device is turned off. Therefore, the switch unit 8
The closed state of 0 and the turning on of the electric device do not always match.
When the switch of the main body of the electric device is turned off (open) while the switch unit 80 of the power supply control unit 400 is in the closed state, the configuration of FIG. 2 cannot detect this.

FIG. 7 shows a power supply control unit 40 for detecting the on / off state of the electric equipment in such a situation.
0 is shown. The power supply control unit 400 includes, in a supply path between the commercial power supply and the electric device, a switch unit 80 that controls conduction and non-conduction of the supply path, a light emitting element 86 that emits light in accordance with on / off of the supply path, Is provided. In addition, a power supply control unit 84 that controls opening and closing of the switch unit 80 in accordance with a control signal from the connected terminal unit 200 and detects on / off of a supply path based on light emission of the light emitting element 86 is provided. This power control unit 84
Includes a coil C1 for controlling the switch, two-stage transistors Q1 and Q2 for driving the coil C1, and a photodiode 88 that operates in response to the light emission of the light emitting element 86.

When connected to the power supply control unit 400, the terminal unit 200 recognizes this, and outputs a control signal for driving the coil C1 from its PC terminal based on an instruction from the host unit 100. I do. PC
When a predetermined H-level control signal is supplied to the terminal, the transistor Q1 current-amplifies the control signal, and the transistor Q2 is driven by the amplified current, and the transistor Q2 operates to supply a current to the coil C1. . Coil C1
, The switch unit 80 is opened, and the power supply path to the electric device is turned off. Also,
When a predetermined L-level control signal is supplied to the PC terminal,
The transistors Q1 and Q2 are turned off, no current flows through the coil C1, and the switch unit 80 is closed. As a result, the power supply path to the electric device is conducted.

Here, when the switch section 80 is closed, if the power switch 90 of the electric device connected to the power supply control unit 400 is in the on state (switch closed state), the commercial power supply is switched off. The power supply path between the electric devices becomes conductive. Accordingly, the light emitting element 86 operates to emit light, and the photodiode 88 detects the light and turns on.

On the other hand, if the power switch 90 of the electric device is in the off state (switch open state), the power supply path between the commercial power supply and the electric device is non-conductive even when the switch section 80 is in the closed state. Become. Therefore, the light emitting element 86 does not operate, and the photodiode 88 does not operate.

DA on the anode side of the photodiode 88
Since the TA terminal is connected, when the photodiode 88 operates and the potential of the DATA terminal changes, this is transmitted to the terminal unit 200 via the DATA terminal. Therefore, the terminal unit 200 can detect, via the DATA terminal, conduction and non-conduction of the power supply path, that is, actual on / off of the electric device.

The detected power on / off state of the electric device is transmitted from the terminal unit 200 connected to the power control unit 400 to the host unit 100, and the host unit 100 can know the power state of the electric device. . When the host unit 100 transmits a control signal to the terminal unit 200 according to the obtained power state, the terminal unit 200 outputs a control signal corresponding to the power control unit 84 of the power control unit 400. Therefore, conduction and non-conduction of the power supply path are controlled according to this control signal, and finally the power supply of the electric device to be managed is controlled. As described above, by providing the power supply control unit 400 with a configuration that detects conduction and non-conduction of the power supply path and transmits this to the terminal unit 200,
Through the terminal unit 200 and the power supply control unit 400, the host unit 100 can detect and control the power supply status of the non-system compatible electric equipment.

The power supply control unit 400 is not limited to the circuit configuration shown in FIG. 7, and controls the conduction and non-conduction of the power supply path between the commercial power supply and the electric equipment, and detects the condition. However, other circuit configurations can be adopted. Further, in the circuit configuration of FIG.
The switch unit 80 is controlled using the PC terminal of
The switch unit 80 based on a control signal from the DATA terminal
May be controlled.

[Identification and Registration of Terminal Unit] FIG. 8 shows a method of assigning an individual ID code to each terminal unit 200. The terminal unit 200 having a circuit configuration as shown in FIG.
When some or all of the buffer 38 and the communication unit) are integrated on the same circuit board and configured as one integrated circuit (LSI), the LSI and necessary elements are mounted on a circuit mounting board. You. At this time, the LSI is mounted on a circuit mounting board, and the LSI is mounted by wire bonding.
Are connected to the corresponding terminals on the circuit board.

In this system, individual IDs are assigned to each terminal unit LSI using this wire bonding process.
Attach the code. Specifically, as shown in FIG.
When connecting the terminal unit LSI to the circuit board,
Only the code setting terminal corresponding to the ID code assigned to each terminal unit 200 is bonded to the plurality of formed code setting terminals, and the remaining code setting terminals are left open (not connected). After the necessary LSI terminals are connected to the circuit board through these steps, each terminal unit LSI reads its ID code by accessing its own code setting terminal, and reads this ID code. It is used as an ID code assigned to itself.

For example, as shown in FIG. 8B, a p-type transistor Tr1 and a pull-up resistor are connected to each code setting terminal and a power supply, and an n-type transistor is connected to the ground. The transistor Tr2 is connected.
Also, all the wire-bonded terminals are connected to GND on the circuit board.

When reading the ID code, the transistor T
If r1 is turned on, "1" is read from a terminal that is not wire-bonded, and "0" is read from a terminal that is wire-bonded. The transistor Tr2 is unnecessary when reading the code from the code setting terminal and can be omitted. However, it is possible to prevent the potential of the terminal, particularly the potential of the terminal that is not wire-bonded, from becoming unstable. Therefore, as shown in FIG. 8B, it is preferable that this transistor Tr2 is connected between the code setting terminal and the ground, and is turned on except when the code is read.

It should be noted that the I set from the code setting terminal
The circuit configuration for reading the D code is not limited to the circuit configuration shown in FIG. 8B, but may be another configuration as long as the presence or absence of the wire bonding to the terminal can be detected.

As an ID code setting method,
In the wire bonding process for LSI terminals,
ID to terminal unit 200 depending on bonding
Instead of the method of assigning codes, a conventional method of setting a single code to an IC can be used. For example, ID code information may be stored in advance using an EEPROM or the like, or a switch may be provided on a circuit board to set the ID code by turning on and off the switch. Alternatively, after the wire bonding step, of the terminals on the circuit board connected to the terminals of the LSI, only the terminal corresponding to the ID code can be further connected by a jumper.

However, for example, when an EEPROM or the like is used or a switch is provided, the number of circuit elements increases accordingly. In the method of connecting using a jumper, a separate step of connecting a jumper after wire bonding is required. This leads to increased manufacturing costs. On the other hand, if the ID code is set together with the connection of the other terminals at the time of wire bonding as described above, the programming of the wire bonding apparatus can be set as desired, and the ID code can be automatically set without increasing the number of steps. Can be set. Therefore, the ID
It is possible to suppress an increase in the manufacturing cost of the terminal unit 200 due to the provision of the code.

Next, a method of registering the ID code of each terminal unit 200 in the host unit 100 will be described.
Registration of the ID code in the host unit 100 is performed by directly inserting the terminal 50 of the terminal unit 200 into the terminal unit insertion section 26 provided in the host unit 100 as shown in FIG.

The terminal unit 200 includes a communication unit and a microcomputer 30 and has the same configuration as that shown in FIG.
As shown in FIG. 2B, a terminal 50 for directly performing data communication with the system-compatible electric device or the power supply control unit 400 and the host unit 100 is provided. Terminal 50 is
As described above, the four-pole terminals VDD (CS), PC, D
It has ATA and GND. Depending on whether the terminal unit 200 has an internal power supply (battery), the VDD terminal and the CS
Although the terminals are interchanged, they have basically the same configuration.

Further, when the terminal unit 200 is connected to a system-compatible electric device, the PC terminal is simply used to keep the voltage level inside the terminal unit 200 constant. On the other hand, the power supply control unit 40 for the terminal unit 200 to control the non-system-compatible electric equipment.
When connected to 0, it is necessary to control the switch unit 80 arranged on the power supply path of the power control unit 400. Therefore, a control signal to the switch unit 80 is output from the PC terminal having a higher current supply capability than the DATA terminal,
The DATA terminal is used to detect conduction and non-conduction of the power supply path. However, the control signal may be output from the DATA terminal of the terminal unit 200 as in the case where the control signal is connected to a system-compatible electric device.

As shown in FIG. 9, the insertion section 26 of the host unit 100 includes an interface circuit and the terminal unit 2.
00 terminals (VDDS, RR
Q, DATA, GND). Host unit 10
0 VDDS (VDD supply) terminal is the terminal unit 20
0 is a terminal for supplying the power supply VDD to the terminal unit 200 via a transistor when the internal power supply is not provided, and the GND terminal is set to the reference potential GND of the host unit. This is a terminal for matching the reference potential. Also, RRQ (regist req
est) terminal is connected to the terminal unit 200 by the host unit 1
It is a terminal for determining whether or not it is connected to 00. The DATA terminal of the host unit 100
When the terminal unit 200 is connected, its DATA
A terminal for performing asynchronous bidirectional serial communication for ID code registration with the terminal.

The procedure for registering the terminal unit 200 (ID code) in the host unit 100 will be described below with reference to FIG. First, the terminal unit 200 to be registered is connected to the host unit 100 as shown in FIG.
21). The microcomputer 12 of the host unit 100 communicates with the terminal unit 2 via the RRQ terminal shown in FIG.
It is determined whether or not 00 is connected (S1). When it is recognized that the connection is made, "terminal recognition" is notified to the terminal units 100 via the respective DATA terminals by asynchronous bidirectional serial communication (S2). Further, a request to start registration of the ID code is made to the terminal unit 200 (S
3).

The terminal unit 200 has an internal power supply (battery)
Is not provided, the system is started by receiving power supply from the host unit 100, and then the microcomputer 30 of the terminal unit 200 causes the host unit 100 to execute itself ( It is determined whether (terminal side) has been recognized (S22). If it is determined that the host unit 100 recognizes itself (S22, yes), the terminal unit 2
00 further determines whether an ID code registration start request has been made from the host unit 100 (S2).
3). When there is a registration start request (yes at S23), the terminal unit 200 transmits its own I
The ID code read from the D code setting terminal is transmitted to the host unit 100 (S24).

The host unit 100 is connected to the terminal unit 2
When the ID code from 00 is received (S4, yes),
The received ID code is registered in the EEPROM 18 in the unit 100 (S5). When the registration is completed, the host unit 100 notifies the terminal unit 200 of the completion of the registration (S6) and sends back the registered ID code.

The terminal unit 200 is connected to the host unit 1
It is determined whether registration completion has been reported from 00 (S2).
5) If there is a report (S25, yes), it is determined whether the transmission ID code returned next and the own ID code match (S26). If both ID codes match (S26, yes), the host unit 100
Reports "terminal registration success" (S27). Conversely, if the two ID codes do not match (S26, no), it reports "terminal registration failure" (S28).

The host unit 100 is connected to the terminal unit 2
Based on the report of the terminal registration success or failure from 00, it is determined whether the terminal registration is successful (S8), and if successful (S8, yes), a registration success message is displayed on the display panel (S9). In the case of failure (S8, n
o), a registration failure message is displayed on the display panel (S
10).

According to the above procedure, simply by connecting the terminal unit 200 to be registered to the host unit 100, the ID code of the terminal unit 200 can be automatically registered. After the registration is completed, the registered terminal unit 200 is connected to a power control unit 40 for controlling a desired system-compatible electric device or a non-system-compatible device.
Connect to 0. Thus, if wireless communication is performed between the host unit 100 and the terminal unit 200 using the ID code, a specific terminal unit 200 among the registered terminal units 200 can be arbitrarily selected without error, and the system-compatible electric device can be selected. Alternatively, it is possible to control a non-system-compatible electric device via the power supply control unit 400.
If the ID code is set to about 32 bits,
It is extremely unlikely that the codes match between the terminal units 200, and the terminal units 200 can be reliably identified.

As described above, by connecting the terminal unit 200 to the host unit 100 and automatically registering its ID code, the system user can check the ID code assigned to the terminal unit 200, and The troublesome work of registering the information in the 100 is not required, and erroneous registration can be reliably prevented. In addition,
The registration of the ID code of the terminal unit 200 does not necessarily require the terminal unit 200 to be directly connected to the host unit 100. Even if wireless communication is used based on a request from the host unit 100, a procedure similar to that of FIG. Thus, the ID code of the terminal unit 200 can be registered.

The type and management items of the system-compatible electrical equipment to which the registered terminal unit 200 is connected, and the setting of the type of electrical equipment connected via the power supply control unit 400 are, for example, the ID to the host unit. Following the code registration, the user presses the setting button 16a in FIG. 4 to shift to a desired setting mode, and displays and sets a menu on the display panel. Alternatively, after registering the ID code, the terminal unit 200 can be connected to the electric device or the power control unit 400, and then the setting can be performed by operating the setting button 16a of the host unit 100.

If it is determined in step S8 that the registration of the terminal unit has failed, the registration procedure shown in FIG. 11 is executed again until the registration succeeds, or the registration procedure is repeated a predetermined number of times. . Further, since the registration failure may be caused by a connection failure or failure of the terminal unit, in the case of registration failure, the ID code registration procedure of the terminal unit 200 is forcibly terminated without executing a retry. You may. In this case, the operator
The terminal unit 200 is replaced with the host unit 100, or the terminal unit 200 is discarded and a new terminal unit 200 is used. Here, in this system,
By making the terminal unit 200 as simple as possible, an inexpensive terminal unit 200 can be realized.
Therefore, even if the registration fails, the terminal unit 200
However, the economic burden on the system user can be reduced.

[Time Management] A centralized time management mechanism in the centralized management system according to the present embodiment will be described.
Currently, many electric devices have a built-in clock function and timer function, and each such device operates based on its own clock. However, at the time of new purchase or after a power outage, the time must be set by a different method for each device, and since the clock error differs for each device, adjustment is troublesome.

In the present system, for example, the microcomputer 12 of the host unit 100 has a clock function and a timer function, so that each terminal unit 200 can be managed based on the clock and timer functions of the host unit 100. Become. The setting of the time in the host unit 100 is performed by, for example, pressing the setting button 16a to shift to the time setting mode and inputting the current time.

To set the timer, the user pushes the setting button 16a of the host unit 100 and shifts to the timer setting mode. Further, each of the electric devices or the power supply control unit 400 (terminal unit 200) for functioning the timer is selected using the scroll button 16c, and the timer operation time is set. Thus, when the set time is reached based on the clock of the host unit 100, the target terminal unit 200
, The host unit 100 instructs the start or stop of the operation by wireless communication. Therefore, a system-compatible electric device to which the terminal unit 200 is connected, or a non-system-compatible electric device connected to the power control unit 400 via the terminal unit 200 operates based on this command.

At present, except for television and audio equipment,
In many cases, the timer is cleared when the timer set time comes. It is troublesome work to go to the installation location of each electric device every day and individually set a timer, but in this system, using a single host unit 100,
Arbitrary timer times can be set for a plurality of electric devices by the same procedure, and timer setting work can be easily performed.

Regarding the electric equipment whose operation is to be started and stopped at the same time every day, even if the electric equipment has no function, it is connected to the system-compatible electric equipment or the power control unit 400 on the host unit 100. What is necessary is just to select the non-system compatible electric device (actually, select the corresponding terminal unit 200) and set so as to continue the timer function. Since the host unit 100 adopts a configuration in which a battery is incorporated, the clock of the host unit 100 does not stop even if a power failure occurs. All you have to do is reset the 100 clock,
There is no need to set the time for each electric device.

By setting the timer for the host unit 100 as described above, the air conditioner, the electric carpet, and the audio device in place of the alarm are operated at a predetermined time, for example, every morning based on the clock of the host unit 100. It is possible to control the electric rice cooker to operate at the time. Further, for example, if a certain period of time in the evening is managed such that the lighting equipment in the building is automatically turned on, it is possible to enhance the security effect when the user is away. Conversely, at a predetermined time, control such as stopping the operation of the air conditioner, the electric carpet, and the lighting equipment can be performed, so that it is possible to prevent forgetting to turn off the light, etc., thereby saving electricity and preventing fire. .

In this system, not only the timer function but also a function of automatically adjusting the built-in clock to an accurate time can be provided to the host unit 100. In this case, a time information receiving circuit may be provided in the host unit 100. Currently, radio broadcasting (440H
z, 880 Hz), for example, a time signal at noon is transmitted, and a standard radio wave JJY (5,
(8, 10 MHz).

The time information receiving circuit receives the time information from these broadcasts and adjusts its own clock according to the received time information, so that the clock in the host unit 100 can operate at the correct time. Can be. Since it is not necessary to constantly adjust the time, the time information receiving circuit is activated once or several times a day at a predetermined time, for example, based on a clock in the host unit 100, and based on the obtained time information. It is only necessary to adjust the time of the clock.

When the system-compatible electric equipment has an extended function that can be specially managed by the centralized management system, the accurate time information obtained by the time information receiving circuit is transmitted to the terminal unit 200 via the terminal unit 200. Wireless communication may be performed with the device. Thus, each electric device having the extended function can adjust its own built-in clock based on the obtained time information.

[Power Supply Batch Control] In this system, since the electric devices are centrally managed, it is possible to cut off the power supplies of a plurality of electric devices collectively. Currently, electric stoves and the like are often equipped with earthquake countermeasures, but not all electric stoves and all electrical devices are equipped with earthquake countermeasures. Therefore, when a disaster such as an earthquake occurs, it is necessary to immediately turn off the power of an electric device that may generate heat or ignite before evacuation. However, since a large number of electrical devices are used in one home, it takes time to surely turn off the power of all the electrical devices one by one.

Here, the breaker controls the power supply within its management range, and the breaker can turn off the power supply within the management range collectively. However, the breaker is not automatically turned off unless there is a short circuit or a short circuit, and is often set in a place where it is hard to reach and few people go. Therefore, there is a case where it is not possible to evacuate by turning off the breaker when a disaster occurs.

Therefore, in this system, as shown in FIG. 4, the host unit 100 is provided with a power-off button 16b as an operation button. When the button 16b is pressed, the host unit 100 immediately transmits the signals to the terminal units 200 connected to the target system-compatible electric device and the terminal units 200 connected to the power control unit 400 for controlling the non-system-compatible electric device. , And automatically transmits a control signal for instructing a power-off of the electric device. Thus, it is possible to control the power supply of necessary electric devices to be turned off collectively by simply pressing the operation button of the host unit 100.

The electrical devices to be turned off by the batch off button 16b can be set in the host unit 100 in advance. For example, as shown in FIG. 12, an electric device such as an electric rice cooker, an iron, an oven, and an electric stove that is likely to generate heat or fire in the event of a disaster can be set as a device to be controlled by the batch off button 16b. In addition, the necessary electric devices can be turned off. In addition, it is also possible to set so that the power supply control units 400 that control all the system-compliant electric devices and the non-system-compliant electric devices registered in the host unit 100 are collectively turned off via the corresponding terminal units 200.

Further, when the ID code of the terminal unit 200 is registered, the type of the electric device (for example, a heating device such as an electric stove, an electric carpet, or an electric blanket) associated with the terminal unit 200 is registered. Can also. If such registration is made, the batch off button 16b
When the button is pressed, the host unit 100 may automatically select a type of device that needs to be controlled from the registered types of electrical devices and perform off-control.

Since the host unit 100 can be configured to be portable, if it is always kept at hand, for example,
Even if an earthquake occurs when you cannot release your hands or cannot operate immediately, such as when you are preparing meals or sleeping at the kitchen, the batch off button 1 of the host unit 100 at hand
By pressing 6b, it is possible to immediately turn off the power of not only nearby electric equipment but also electric equipment in a remote room. For this reason, forgetting to erase some of the devices can be reliably prevented.

When the batch off button 16b is pressed, a configuration in which the timer function which is automatically operated every day is cleared is also applicable. In the case of evacuation due to a disaster or the like, it is conceivable that the timer function of the host unit 100, which is used on a daily basis, operates in an unmanned building after the evacuation to operate the electric equipment. When the batch off button 16b is used, such a problem can be avoided by clearing the timer function for all devices.

Further, while the power of necessary electric equipment is controlled to be turned off at the time of disaster or the like, for example, in order to facilitate evacuation, for the electric equipment such as lighting equipment, the collective off button 1 is used.
When the user presses the button 6b, the host unit 100 can automatically turn on the corresponding electric device by wireless communication.

Further, the above-described batch turning-off function can be used not only at the time of disaster but also at the time of going out and the like, and the power supply of necessary electric equipment can be turned off at once. With this function, forgetting to turn off can be reliably prevented, and the trouble of confirming the power on / off of each electric device can be omitted. An operation button dedicated to going out may be separately prepared. In a configuration in which the above-described timer function is automatically cleared when the batch off button 16b is pressed, it is preferable to provide another operation unit dedicated to going out.

Next, a description will be given of a system for automatically detecting an earthquake and executing a collective power cut-off of a target electric device. When an earthquake occurs, human
In some cases, the 00 batch off button 16b cannot be pressed. Even in such a case, if the system is configured to automatically and automatically shut off the power of the electric device, a secondary disaster such as a fire caused by the electric device can be prevented.

This system can be realized by, for example, installing a vibration sensor 60 having a wireless communication function as shown in FIG. The vibration sensor 60 is a sensor that notifies the host unit 100 by wireless communication when a vibration exceeding a predetermined level is detected. However, the terminal unit 200 can be connected to the vibration sensor 60 in the same manner as other electric devices, and the communication between the connected terminal unit 200 and the host unit 100 detects the vibration of the vibration sensor 60 by the host unit. A configuration for notifying 100 may be employed.

The operation procedure will be described below with reference to FIG. When the vibration sensor 60 detects vibration having a predetermined strength or more (S31, yes), a vibration detection report is wirelessly transmitted to the host unit 100 (S32).
The host unit 100 receives the vibration detection report (S33), and in that case (S33, yes), the host unit 100 automatically sends the terminal unit 200 connected to various electric devices or the power supply control unit 400 as shown in FIG. Then, "power off" is transmitted together with the ID code. In addition, in order to prevent confusion at the time of evacuation, power-on, that is, "lighting-on" is transmitted to the terminal unit 200 connected to the lighting equipment together with the ID code (S34). If the lighting device is not compatible with the system, the terminal unit 20 corresponding to the power control unit 400 to which the lighting device is connected.
A signal for turning on the lighting device is transmitted to 0.

When each terminal unit 200 receives the control signal from the host unit 100 (S35, S4
0), it is determined whether or not the ID code assigned to the control signal matches the ID code of its own terminal unit 200 (S36, S41).

If the ID codes match and the control signal is a power-off control of the connected electric device (S36, yes)
s) The power of the system-compatible electric device is turned off by outputting a power-off signal from the DATA terminal of the terminal 50, and the power of the system-non-compatible electric device is turned off via the power control unit 400.

If the ID codes match and the control signal is power-on control of the connected electrical equipment (S41, yes
s), a power-on signal is output from the DATA terminal of the terminal 50 to turn on the system-compatible electric device, that is, to turn on the lighting device,
Turn off the power of the lighting equipment not compatible with the system via.

If the ID codes do not match (S3
6: no or S41: no), the terminal unit 200 does not operate, and the corresponding electric device is not controlled.

After executing the power off / on control for the above-mentioned system-compatible and system-non-compliant electric devices, the terminal unit 200 determines whether or not those electric devices are actually in the off or on state from the DATA terminal thereof. Judgment is made from the obtained signal (S38, S43). If the power-off of the electric device has been completed based on the power-off control (S
38, yes), the power-off completion is transmitted to the host unit 100 (S39). If the power-on of the electric device (lighting of the lighting device) is completed based on the power-on control (S43, yes), a power-on completion is transmitted to the host unit 100 (S44).

The host unit 100 monitors whether there is an operation completion report from each terminal unit 200 (S45), and if there is the operation completion report (S45, yes)
s) It is determined whether or not the operations of all the terminal units 200 that have ordered the operations have been completed (S46). Then, when the operation of all the terminal units 200 that ordered the operation is completed (S46, yes), the host unit 100 displays the completion of the operation on the display panel 10 (S4).
7), complete the power supply collective management work.

Note that the lighting device whose power is controlled to be turned on can be automatically turned off after a lapse of a predetermined period from turning on by, for example, activating a timer function of the host unit 100. In the procedure shown in FIG. 14, the lighting device is turned on in the event of an earthquake, but it is not necessary to turn on the lighting device. In that case, only the necessary power-off control of the electric device is executed.

Here, when the host unit 100 receives the vibration detection direction from the vibration sensor 60, the host unit 100 executes the above-described predetermined control for each terminal unit 200 and also notifies the person of the earthquake. A warning sound can be generated from a built-in speaker, and a warning lamp can be turned on (see FIG. 4).

With such a system, for example, in a state where the hand cannot be released in the event of an earthquake, when there is no person, or when evacuation cannot be performed after turning off the power of the electric equipment at the time of evacuation. Even so, it is possible to automatically detect the earthquake and turn off the power of necessary electrical equipment, so that secondary disasters can be avoided reliably.

In the above description, the earthquake is detected by the vibration sensor 60, and the electric devices are controlled collectively. However, the present invention is not limited to the earthquake. For example, if a smoke sensor or a heat sensor is provided in addition to the vibration sensor 60 shown in FIG. It is also possible to prevent the spread of fire. That is, when smoke detection or heat detection is notified from these sensors, it is determined that a "fire" has occurred, and a warning lamp is turned on, a warning sound is generated, and evacuation is prompted.
According to the same procedure as described above, the host unit 100 collectively turns off the power of necessary electric devices such as heating devices. In addition, control such as turning on a light for a certain period may be performed to facilitate evacuation.

[Security System Function] In the above-described centralized management system according to the present embodiment, the use of an impact sensor, an infrared sensor, and the like makes it possible to provide a security system function to the system. The system configuration may be such that, in FIG. 13, the vibration sensor 60 is replaced with an impact sensor, and this impact sensor is provided, for example, on a door or a window. When the impact sensor detects that an impact of a predetermined level or more is applied to a door or a window, the impact sensor outputs an impact detection signal to the host unit 1.
Tell 00. Based on the shock detection signal, the host unit 100 generates a warning sound from a built-in speaker and turns on a warning lamp in order to notify a person that a shock has been applied (see FIG. 3). The host unit 100 is also provided with a terminal unit 200 provided in the lighting device to turn on a predetermined lighting device that has been set.
, An illumination ON signal is transmitted together with the ID code. Thereby, the corresponding lighting device can be turned on. If the lighting equipment does not support the system,
By controlling the power supply control unit 400 to which the lighting device is connected via the terminal unit 200, the lighting device can be turned on.

According to such a system, when an intruder is detected through a door or a window, this is automatically and promptly notified to a person in the building, and the lighting is turned on to scare the intruder. Becomes possible. If an alarm is provided separately for the centralized management system, the host unit 100 may operate the alarm through the terminal unit 200 to sound an alarm based on the shock detection signal. Can be. As described above, when an impact is applied to a door or a window by an intruder, the illumination is immediately turned on and an alarm is sounded, so that a higher intrusion suppression effect can be obtained.

Further, when an infrared sensor is installed, for example, under a window, in a garden, at a front entrance, or the like, and when the movement of a person is detected, the host unit 100 receives a notification from the infrared sensor and operates via the terminal unit 200 via the terminal unit 200. By activating indoor lighting equipment and lighting equipment at the entrance and sounding an alarm, the intrusion of a suspicious person can be suppressed. Conversely, when there is a visitor, the illumination can be automatically turned on, and a chime can be sounded in the building, or a sound can be output from the speaker of the host unit 100 to perform the intercom function.

Further, the system is not limited to the configuration in which the host unit 100 for centrally managing other electric equipment as shown in FIG. 1 operates by receiving detection signals from these shock sensors and infrared sensors. As shown in FIG. 15, a dedicated host unit 101 having a built-in impact sensor 62 may be separately prepared to perform operations such as turning on predetermined illumination.

In the case of the configuration shown in FIG. 15, the ID code of the terminal unit 200 corresponding to the electric device to be operated when a predetermined impact or movement is detected is registered in the dedicated host unit 101 in advance. . When the shock sensor 62 of the dedicated host unit 101 detects a shock, an operation command is given from the dedicated host unit 101 to necessary electric equipment (such as a lighting fixture) via the terminal unit 200. If the target electrical device is not compatible with the system, the power supply control unit 400 is controlled via the terminal unit 200, and thereby the electrical device is operated.

As shown in FIG. 15, if a dedicated host unit 101 is used for crime prevention, the host unit 100 shown in FIG.
Processing load can be reduced. Therefore, an inexpensive host unit 1 that is portable, has fast processing, and has few items to be processed.
By providing the dedicated host unit 101 while providing the security system function 00, it is possible to add a security system function.
Also, the terminal unit 2 is directly transmitted from the dedicated host unit 101.
00 instead of controlling the dedicated host unit 101
It is also possible to adopt a configuration in which the host unit 100 is once notified of the impact detection, and a predetermined lighting device or the like is turned on by the host unit 100.

Further, the impact sensor 62 does not necessarily need to be built in the dedicated host unit 101, and the terminal unit 200 can be inserted like other electric equipment, and the host unit 100 or 101 is connected via the terminal unit 200.
May be configured to transmit the impact detection.

[Power Saving System] The above-mentioned system can be made to function to save power. FIG.
As shown in FIG. 1, for example, an air conditioner, a television, and a lighting device are placed in a room. Among them, the terminal unit 200 is attached to the system-compatible electric device, and the power supply control unit 400 (not shown) ), And the terminal unit 200 is attached to the power control unit 400. Then, the host unit 300 as shown in FIG. 16 is installed on a wall or ceiling of the room. This host unit 300 has the configuration shown in FIG.
As shown in FIG. 7, a sensor 64 such as a pyroelectric sensor, a motion sensor, or a human body sensor is built in, and the ID code of the terminal unit 200 to be controlled in the room is registered in the EEPROM.

The host unit 300 detects whether or not there is a person in the room by using the sensor 64, and FIG.
When the sensor 64 detects the movement of a person when the person is in the room, the host unit 300 sends a signal to the registered terminal unit 200 to turn on the electric device. Each electric device corresponding to the terminal unit 200 maintains the on state when the electric device is already in the on state.

As shown in FIG. 16 (b), when the person is no longer in the room and the movement of the person is not detected by the sensor 64 for a predetermined period (for example, 15 minutes), the microcomputer 12 sends the registered terminal unit 200 On the other hand, a signal for turning off the power of the device is wirelessly transmitted. The terminal unit 200 receives this signal, and the power of the corresponding device is turned off.

According to such control, when there are no more people, unnecessary electric devices can be automatically turned off. Therefore, it is possible to prevent wasteful consumption of electricity due to forgetting to turn off, and to prevent occurrence of fire due to forgetting to turn off.
On the other hand, as soon as a person enters the room, the sensor 6
4 detects this and turns on the registered electric device, so that the electric device is not turned off when necessary, and can also function as a security system.

In the above description, the host unit 300 containing the sensor is mounted in the room, and the host unit 300 controls the terminal unit 200.
However, it is not limited to such a configuration. For example, a sensor having a wireless communication function or a sensor equipped with a terminal unit 200 is installed in a room, and the detection result of the sensor is used to transmit a host unit 10 common to the building shown in FIG.
0 may be transmitted. In this case, the host unit 1
00 transmits a control signal based on the detection result of the sensor 64 to a predetermined terminal unit 200 to be controlled in the room where the sensor is installed. According to such a method, the power of unnecessary electric devices can be controlled to be turned off as described above, and the power can be turned on immediately after detecting the movement of a person, which can also be useful for crime prevention.

[Others] In the above description, a plurality of electric devices (terminal unit 2
00), the configuration of centralized management is taken as an example, but a plurality of host units 100 may be provided. The plurality of host units 100 can also limit the functions of the host unit 100 corresponding to the slave units, for example, in the relationship between the master unit and the slave units of the telephone. Conversely, exactly the same function and authority may be given.

When there are a plurality of host units 100, the operation of registering the ID code of the terminal unit 200 in each host unit 100 must be executed separately. That is, in order to control the same terminal unit 200 by a plurality of host units 100, each host unit 100
As described above, the terminal unit 200 is directly inserted to perform ID code registration work. However, if an ID code already registered in a predetermined host unit 100 can be copied to another unregistered host unit 100 by wireless communication or the like, duplicate ID code registration work can be omitted.

It is preferable that the host unit 100 has a built-in power supply and is portable in consideration of its operability. In addition, if a plurality of host units 100 are provided, for example, one is placed in a predetermined place and the rest is carried by an operator, it is very easy to use and practical.

Note that the control authority of the plurality of host units 100 for the same terminal unit 200 is the same unless otherwise specified. If commands for the same terminal unit 200 are overlapped, the terminal unit 200 changes to the latest control command. It operates based on the above, and the transmission signal from the terminal unit 200 is received by each of the host units 100 in which the unit 200 is registered.

As described above, when a disaster occurs, an operation of pressing the batch off button 16b of the host unit 100 is performed. Further, even if the system is away from the house where the system is installed, if the distance is, for example, about 30 m to 100 m, it is possible to execute off control of the electric device from outside the house. There is also the possibility of evacuation. Therefore, if the host unit 100 used in such an emergency is provided with a lighting function and a radio receiving function, for example, the operation of the host unit 100 at the time of a nighttime disaster becomes easy, and the evacuation route can be illuminated. This makes it possible to know the disaster situation. Therefore, a more convenient and functional system can be provided as a disaster prevention measure.
