Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system that performs intensive monitoring and control of close and close locations using carrier wave communication using indoor power lines.

As such systems, a few products have been released in recent years. One of them is U.S. Patent No. 4.200.8.
There is one shown in the specification of No. 62.

This is a system that includes a central unit that performs central control and a lamp unit that drives a triac in the same way as an appliance unit that drives a solenoid and turns on a microswitch by a signal sent from the unit.

However, this system had the following drawbacks.

(1) Indoor power lines generate a lot of noise because various electrical devices are connected as loads. For this reason, the transmitted signal from the intimate device may not be read accurately, and the signal may not be working properly.

(2) Custom ICs are used for both intimate and intimate. Chitoshi uses this custom IC to electrically maintain the drive of the solenoid or triac.
In the event of a power outage, all chits are turned off. Meanwhile, at this time intimacy has ceased as well. As a result, during a power outage at night, the lamp gate density is cut off, and it is inconvenient to reset a plurality of lamp gate density after the power is restored because the surroundings are dark.

A system designed to improve these shortcomings is
It is released by another company.

In this system, the child device sends an answerback signal in response to the transmission from the intimate device, and after receiving the answerback signal, the intimate device turns on the LED installed on the panel.
Switch the display.

Therefore, the display will not change unless the slave device is receiving the signal. For this reason, the user will be able to perform the intimate operation again, so that the operation can be performed more reliably. In addition, a latching relay is used for the slave switch, eliminating the disadvantage of the above system against power outages.

However, this second system also had the following drawbacks. That is, both the intimate and slave devices use microcomputers, and when the power is restored, the microcomputers of the intimate and slave devices are reset. For this reason, the display of intimacy L E I),
A situation occurred where the status of the latching relay of the slave device was different. Additionally, latching relays have a disadvantage in principle that they are larger and more expensive than general magnet relays.

An object of the present invention is to provide a system which eliminates the drawbacks of the prior art described above, and which eliminates the use of latching relays. To provide a system capable of setting the state of a slave device to the state before the power outage after power is restored, and making the state of the slave device and the display of intimacy the same.

In order to achieve the above object, the system of the present invention allows control slave devices such as appliance chitai and lamp chitai (hereinafter collectively referred to as control chitai) to respond to transmissions from intimates. A back signal is transmitted, and the control unit receives this answer back signal and switches the display on the display section provided on the panel, and also stores information from the control unit.

Furthermore, by adopting a circuit configuration that includes a backup batch IJ 4, the memory regarding the control status is not erased even in the event of a power outage, and furthermore, the circuit configuration is capable of detecting a power outage state, etc. By doing so, after the power is restored, the control unit sends a transmission signal to the control unit so that the control unit performs the same as the memory described above. On the other hand, the control chip has an inexpensive circuit configuration that does not use a latching relay.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing an example of the configuration of the system of the present invention, in which an outdoor power line 1.2 is connected to a breaker 3 installed indoors. In this embodiment, power lines 4 and 5 via a breaker 3 are connected to a filter 6 that prevents carrier waves from entering and leaking, and the filter 6 and each indoor outlet 9° 13-, 20, 27, 31.35 are connected to each other. Indoor power lines 7, 8
Connected with

Now, the intimacy 12 that corrupts centralized monitoring and control is the electric wire 10. .

11 is connected to the outlet 9, and the appliance wire 16, which is a type of control wire, is connected to the electric wire 14.1.
5 is connected to the outlet 13, and an appliance 19 such as a television is connected to the appliance wire 16.
Suppose that it was connected on 7.18.

Similarly, it is assumed that a lamp plug 23, which is a type of control plug, is connected to the outlet 201 by an electric wire 21.22, and a lighting fixture 26 is connected to the lamp plug 23 by an electric wire 24.25.

Further, a fire sensor slave 30, which is a type of security slave, is connected to the masticatory socket 27 by electric wires 28 and 29, and a gas sensor slave (a type of security slave) 3
4 is connected to the outlet 31 by electric wires 32 and 33, and similarly, an intrusion sensor slave 38 is connected to electric wires 36 and 33.
37 is connected to the outlet 35.

Outlet9. , 13, 20, 27, 31, and 354C are connected respectively, the intimacy 12, the appliance touch 16, the lamp touch 23, the fire sensor slave 3o1, the gas sensor skeleton 34, and the intrusion sensor 38 are first connected. A microcomputer (microcomputer), which is a main component, performs initialization processing (this will be explained in detail later).

Thereafter, the sharp instrument 12 receives the input signal of the key on its panel,
Alternatively, the appliances 16, 23, 30, 34, and 38 wait for signals from the appliances 16, 23, 30, 34, and 38, while the appliances 16 and lamp holder 23 wait for signals from the sharps 12.
They are in a state of waiting for an input signal for a change in turning on or off the fixture 19 and the lighting fixture 26, respectively. In this state, both the appliance unit 16 and the lamp unit 23 are in the off state.

In addition, the fire sensor subframe 30 and the gas 7 sensor subunit 34 are
They are in a state where they are waiting for an input signal indicating an abnormal condition due to fire or gas leak. Furthermore, the intrusion sensor 38 is
It is in a state of waiting for an alarm operation designation signal from the sharp instrument 12 or an input signal indicating an abnormal state from an intruder or the like.

The sharp tool 12 is provided with a back-up battery and a switch (not shown) for connecting the back-up battery to a power terminal of a microcomputer or the like.

When this switch is closed and voltage is supplied to the microcomputer, the microcomputer will perform initialization processing at that point.

It is assumed that this switch is closed when the above-mentioned state is reached. Here, we will briefly explain an example of the operation of the system shown in the figure, using the appliance unit 16 from among the control units and the fire sensor unit 30 from among the security units. We will explain from operation 16. Now, if the user presses a key on the sharp instrument 12, the sharp instrument 12 will transmit a PDM-AM signal of a predetermined code to the electric wire 10.
Send from 11 to outlet 9. The signal sent in this way passes through the indoor power line 7.8 from the outlet 9 and reaches the outlet 3. Wire 1 from electrical outlet 3 to Sarah
Pass through 4 and 15 and enter the appliance store 16.

The appliance controller 16 compares the received signal with a predetermined code and ignores the difference. If they are the same, the code of the received signal is checked, and if it is designated as on, power is supplied to the appliance 19, and if it is designated as off, the power supply is stopped. It works like this.

Here, the transmission signal is synchronized with a specific phase from the zero cross of the AC voltage (50Hz or 60I(z)) applied to the indoor power lines 7 and 8.

At the same time, the appliance station 16 sends an answerback signal to the sharp tool 12. This answerback signal (PD
M-AM signal) enters the sharpener 12 by traveling in reverse along the same thread path as described above. The sharp device 12 receives the answerback signal from the appliance station 16, confirms that the previously transmitted signal has reached the appliance station 16#, stores the operating state of the appliance station 16, and Display its status.

Next, if the switch of an appliance 19 such as a television is changed by the user, the appliance switch 16 detects a change in the current flowing through the line 17 and 18 from the previous state, and detects the change from the previous state. When the switch of the appliance 19 is turned on or off (it is determined whether this is switched or not), the appliance switch 16 changes its state to be on or off. The supply of power to the appliance 19 is started or stopped.

At the same time, the appliance child device 16 transmits a signal with a predetermined code to the sharp tool 12. Sharps 12
receives this signal and switches the display, and also
The memory related to the operating state of the Bryans slave unit 16 is also switched.

Next, it is assumed that under the above condition 1, the power supply from the indoor power line 7.8 is stopped due to a power outage or the blower switch 3 being turned off. The appliance unit 16 completely stops operating and is in an off state because the Banokkuanobunoku tuna 1 noise is 71 low.

On the other hand, the sharp device 12 is in a state where the power supply is maintained, but no display is made, and manual power is ignored.The method by which the main device 12 detects a power outage is as follows: For example, it depends on the presence or absence of a phase signal for synchronizing transmission and reception.

When the power outage is eventually restored or the breaker 3 is turned on and power is supplied to the indoor power lines 7 and 8,
The appliance controller 16 performs initialization processing and waits. On the other hand, the intimate device 12 detects the restoration of power and sequentially sends a message to set the control slave devices to the state before the power outage. However, it is transmitted in order to turn on only the control chip that was in the on state.

Through the above-described procedure, the appliance memory 16 is reset to match the stored contents of the sharp instrument 12.

Next, the operation of the fire sensor search 30 will be explained.

Fire Detector 30 monitors the occurrence of fire based on the presence or absence of smoke.

If a fire breaks out now, the fire detection density 30 is:
When a fire is detected, a buzzer sound is generated, and a PDM-AM signal of a predetermined code is sent to the wire 28.
, 29 to outlet 27 and from outlet 27 to indoor power line 7
, 8 and reaches the outlet 9. Further, this signal is transmitted from the outlet 9 through the wire 10.11 to the sharps 12.
to go into.

When the sharps 12 receives the transmission signal from the fire detection sensor 30, it stops displaying the control signals 16 and 23, displays a fire indication, and generates a buzzer sound. Further, the key human power related to the control chips 16 and 23 is ignored.

The fire sensor 30 generates a buzzer sound until the fire detection signal disappears, and also transmits a PDM-AM signal of a predetermined code to the sharp instrument 12 at regular intervals.

The sharp tool 12 receives this signal and generates a buzzer sound, but when a predetermined time elapses after receiving the transmission signal from the fire sensor search unit 30, the buzzer sound is generated and the fire is displayed. This is to stop the process and return to the original state.

Therefore, when the transmission signal from the fire sensor 30 disappears, the sharps 12 returns to its original state.

Here, the transmission signal (code) is
As previously explained with respect to 6, indoor power lines 7,8
It is synchronized to a specific phase from the zero crossing of the voltage applied to the voltage.

Next, assume that a power outage occurs or the breaker 3 is turned off.

The configuration of the fire sensor search unit 30 will be described in detail later, but it is broadly divided into a sensing unit similar to that of commercially available alarms and a communication unit that performs carrier wave communication. The sensing part is battery-powered and detects the occurrence of a fire based on the presence or absence of smoke, and sounds a buzzer. The communication section checks the fire occurrence signal from the sensing section and the battery voltage, and transmits a carrier wave signal to the sharp tool 12.

Therefore, in the event of a power outage or the like, when a fire occurs, the fire sensor 30 detects the fire and generates a buzzer sound, but does not transmit the signal to the sharps 12.

In addition, in the above transmission, the sharp device 12, the child device 16.2
3, 30, 34, and 38 are first received, and if there is no signal (same as noise), transmission is started.

In addition, the display of the sharp instrument 12 gives priority to the sequilitary coccyx 30 , 34 , 38 over the control chip 1623 ,
Further, within the security devices 30, 34, and 38, the gas detection detection density 34 is given priority over the intrusion detection detection density 38, and the fire detection detection density 3° is prioritized over the gas detection detection density 34.

Furthermore, the security bones 30, 34, and 38 have a battery, and when the voltage of this battery drops below a predetermined level, a buzzer sound is generated and the sharp object 1
Send a predetermined transmission code to 2. Sharps 12
is displayed in the same way as above and generates a buzzer sound.

Next, an example of the circuit configuration of the sharp tool 12 shown in FIG. 1 will be briefly described with reference to FIG. 2.

supply c.

Further, the power supply circuit 84 performs full-wave rectification of the AC voltage supplied by the electric wires 10 and 11, and sends a pulsating voltage signal to the phase signal circuit 86. The phase signal circuit 86 generates a clock signal from this pulsating voltage signal at approximately zero cross of the above-mentioned AC voltage, and outputs the clock signal to the interrupt input section lNTl of the microcomputer 98.

The power supply circuit 84 or the backup battery circuit 85 sends a voltage signal to the reset circuit 87.

The reset circuit 87 receives a DC stabilized voltage Vcc which is the output of the power supply circuit 84 or the back-up battery circuit 85.
When it falls below a predetermined level, the operation of the microcomputer 98 is stopped, and when it rises above a predetermined level, a reset signal is sent to the reset input section RBSBT of the microcomputer 98.

89 is a negative feedback circuit for oscillation, which sends two signals for oscillation to the microcomputer 98. The microcomputer 98 operates by generating a clock from this signal.

Further, the oscillating negative feedback circuit 89 sends one high frequency signal for the indoor power line carrier to the transmitting circuit 99#.

The transmitting circuit 99 logically ANDs the high frequency signal sent from the oscillation negative feedback circuit 89 and the transmission code sent from the microcomputer 98, and sends the signal to the coupling circuit 100.

The coupling circuit 100 is connected to the electric wire 10.11, and when a signal is sent from the transmission circuit 99, it is sent as a sine wave to the electric wire 10.11. Conversely, when the indoor power line carrier signal is sent from the electric wires 10 and 11, the coupling circuit 10
0 is tuned to this and sends a signal to the receiving circuit 101.

Next, if the result of the power failure determination is 1YES, the output of the phase signal circuits 86, 106, 127 is obtained by counting instruction cycles (internal timer) of the phase signal circuits 86, 106, 127 and the microcontrollers 98, 113, 134. If it is not detected within a specific time, the process returns to the beginning of the initialization process.If the result of the power failure determination is 'NO', an interrupt is generated by the clock that is the output of the phase signal circuits 86, 106, and 127 (INTI side). and
Waits for an interrupt to occur.

Now, assuming that an interruption occurs due to the NT1 manual interrupt signal, the routine shifts to the synchronization process 1NT1 shown in FIG. Note that when an interrupt occurs, the interrupt becomes disabled.

In the synchronized processing lNTl routine, first, it is determined whether or not it is a sharp instrument 12. If it is a sharp instrument 12, as shown in FIG. 3 (5), the first scan signal (SCANI) is raised and the LEDs 1 to 4 of the LE3D array circuit 95 in FIG.
Display data is outputted to start displaying, and then key data of keys 1 to 4 (unit keys) of the key array circuit 96 is read.

Next, each switch in the switch circuit 97 is read.

However, in the case of reading an intrusion switch, it is necessary to determine whether the switch has been switched and if it has been switched.

In order to be the same in either case, a control is provided in the unit code setting switch reading process.

In the process of reading the house code setting switches 93, 111 and 132, the switch data is read and the house code in the transmission code is set.

Next, the frequency is determined to be 59 Hz, and if it is not 59 Hz, the process immediately moves to transmission/reception processing (return), and if it is 50H2, it moves to transmission/reception processing (return) after a predetermined delay.

In the transmission/reception process (1), the first half of a 1-bit carrier wave signal (pulse) is processed. That is, first, the receiving circuit 101

If there is a signal on the contrary or there is no transmission request, the receiving circuit 101 sends a signal to start the transmission to the receiving circuit 101.
It performs processing such as reading the outputs of 116 and 138.

However, in the case of transmission, if the signal (1-bit data of the code) is '0', that is, a short carrier wave signal is sent, the latter half of the carrier wave signal (pulse) is also processed here.

Next, the first scan signal (SCANI) (7) is subjected to fall processing. That is, if it is a sharp instrument 12, the LED array circuit 95 finishes displaying Ll(D1 to D4.
If the number is 16, 23, 30, 34, 38,
Since the first scan signal has not been raised from the beginning, there is no change.

After this, the sharps judgment is performed again. If it is a sharp object, the second
Raise the scan signal (SCAN2) of
The display data of LEDs 5 to 8 of the ED array circuit 95 is outputted to start displaying, and the key data of the keys 5 to 8 of the key array circuit 96 is read. After this, send/receive processing (
Move on to 2). On the other hand, if the object is not a sharp object, the process proceeds to the transmission/reception process (2) after passing through the delay process (2) to save the same amount of time as the process for raising the second scan signal.

In this transmission/reception processing (2), the latter half of the 1-bit carrier wave signal (pulse) is processed. In other words, if a signal for transmission is being sent to the transmitting circuits 99, 114, 136, a signal is sent to stop it, and conversely, if receiving is in progress, a carrier wave signal is sent to the receiving circuit 101.
, 116, and 138 are appropriate, and whether the signals are N'' or '0''.

Next, the frequency of 950Hz is determined, and as described above,
If it is 50H2, it is determined whether or not it is a sharp object after a predetermined delay has elapsed. If it is a sharp object, the process moves to key discrimination processing, and if it is not a sharp object, it is determined whether or not it is a control child device. If it is a control child device, it moves to control processing, otherwise it moves to security processing.

In the sharp instrument key discrimination process, the key data of the key array circuit 96 of FIG. 2 read in advance and the switch circuit 97 are used.
It is determined whether the input data of the on switch and off switch of the controller is appropriate. If the input is correct, it sets a transmission code according to the key or inch, processes the transmission request, stores the input data, or cancels it. Sometimes, a signal is sent to the buzzer circuit 90 in FIG. 2 to generate a buzzer sound.

Next, the falling of the second scan signal (8C'AN2) is performed, and the display of the LEDs 5 to 8 of the LED array circuit 95 is completed. Furthermore, a third scan signal (SCA
N3) and LHD9~ of the LED array circuit 95.
Display data of No. 12 is outputted to start displaying, and the key data of keys 9 to 12 of the key array circuit 96 are read, and the process moves to received data discrimination processing.

On the other hand, in the hand control process, if it is the appliance slave unit 16, the load on/off detection circuit 117 shown in FIG.
The output signal (2 bits) is read and compared with the previously stored output signal (2 bits). If the two are different,
Determines the change status, sends a signal to the operating display LED and 15A power relay circuit 119 to drive or stop them, stores the subsequent 2-bit output signal, and also sets the transmission code and requests transmission. Process. After this, the process moves to delay (4) processing.

Furthermore, in the case of security processing, the interface circuit 181 in FIG. Check whether there are 〃) and ・). At the same time, if there is an output indicating that a fire has started or the battery has run out, a signal is sent to the operating display LnD circuit 140 and the LE
D is turned on, a transmission code is set, a send request is processed, and the process moves to delay (4) processing.

Note that the time required for control processing and security processing is programmed so that they are the same. Delay (4) processing is provided for the purpose of eliminating the difference between the time required for control processing or security processing and the predetermined time from key discrimination processing to third scan startup processing in the case of sharp objects. , in the case of hand fat,
After a predetermined delay has elapsed, the process moves to received data discrimination processing.

In the received data discrimination process, the reception code obtained in the transmission/reception process (1) and the transmission/reception process (2) is checked. In the case of the machine 12, processing such as creating display data for the T and H'D A1/A circuits 95 in FIG. conduct. Also, if the received signal is from the sequiliary bone, L
The time between the display of ED and the generation of the buzzer sound is counted (the number of times this process is passed is counted), and after a predetermined period of time, the original state is restored.

On the other hand, in the case of control ``1-ru fetus'', if it is the appliance fetus 16, the transmission command from the machine 12 is 17.
Therefore, a signal is sent to the operating indicator LED and the t5A power IJ l/- circuit 119 in FIG. Convert data to special value. In the case of a sequilite, only the intrusion sensor cotoid 37 turns on and off the alarm operation (generating a buzzer sound and transmitting ft to the making device 12) in accordance with the transmission command from the making device 12. I will omit that explanation.

After the above-mentioned received data discrimination processing, a frequency of 5QHz is determined, and if the frequency is 50Hz, after a predetermined delay has elapsed, the fall processing of the 3rd scan signal is performed. In this 5, if the machine is 12, the JJ E D A L/I circuit 95]
L, g I) Finish displaying 9 to 12, and display fetus bone 16,
If it is 23, 30, 34.38, the third scan signal has not been raised from the beginning, so there is no change. 16th, friendly and coterminous bones are determined. When the machine is manufactured 4C, raise the fourth scan signal (SCAN4) and select L E I in Fig. 2.
) LJ'1D of array circuit 95 (SECU1~81'':
Cu2) display data is output to start displaying, and the keys (MgMO, AI, LOF'F') of the key array circuit 96 are output.
) (7J4 --- Take Day 1 as Ja and shift to buzzer timer processing.

In the buzzer timer process, when a steady sound is generated in response to the input of the key of the key array circuit 96 and the on/off switch of the switch circuit 97 in Figure 2, the time of the buzzer sound is counted, and after a predetermined time elapses, Buzzer circuit 9
0 signal to stop the buzzer. In addition,
This time count depends on the number of times the buzzer timer process is passed. After this, the process moves to 50Hz determination processing.

On the other hand, if it is not a manufacturing tool, delay (6) processing is performed and the process moves to 50 Hz determination processing. As described above, in the 50 Hz determination process, if the frequency is 50 Hz, a predetermined delay elapses before proceeding to the next process. After this process, the process moves to delay (8) process, and then to the fall process of the fourth scan signal.

The process of falling the fourth scan signal is similar to the process of falling the third scan signal, and is
LEDs of array circuit 95 (SBCU1 to 5ECU4)
to end the display.

Next, the interrupt on the INTI side is canceled and the process moves to the delay (9) processing number.

The time from the beginning of the synchronous process NTl to almost the center of this delay (9) process is programmed so that it is the same no matter which branch of the above process passes, and as shown in Figure 3 (1). ) according to the half-cycle time of the power supply voltage.

Therefore, unless a power outage or other condition occurs, an interrupt occurs during the delay (9) process, and the process returns to the beginning of the synchronous process INTl. In the case of a power outage, etc., the process passes through the delay (9) process, performs the interrupt prohibition process again, and moves on to the next process. Here, we will again judge the friendship and the bones. If it is not a manufacturing device, the process goes through the delay (10) process, cancels the interrupt on the lNTl side, and waits for the interrupt.

On the other hand, if it is a machine, the process moves to power outage processing.

In the power outage process, first, a stop signal is sent to the buzzer circuit 90 and the transmitting LED circuit 94 in FIG. 2, and then the display data of LEDI to 12 of the LED array circuit 95 is read out, and ON input data is set. It also processes transmission requests. In other words, the control key that is set to on is automatically selected to create a state in which these unit keys are input, and a state in which the main on switch is input. After this processing, the interrupt on the INTI side is canceled and the interrupt waits.

Eventually, when the power outage etc. is restored, the synchronization process returns to the beginning of NTI, executes each process, and starts transmission by the send/receive process (re and send/receive process (2). In this way, the control skeleton The transmission signal from the sharp device returns the state to the state immediately before a power outage, etc. occurred.Although the widths of the scan signals (8CAN1 to 8CAN4) are not the same, they are similar to the peripheral circuits of the LgD array circuit 95 in Fig. 2. By appropriately selecting the constant, specifically, the resistance value of the current limiting resistor connected in series with the LED, the brightness was made to be the same.

As described above, according to the system of the present invention, the sharp instrument memorizes and displays the state of the control cotoid, and sends a signal to the control cotoid so that the state will be as in the memory after the power is restored. Therefore, there is no disadvantage that the display of the sharp instrument and the operating state of the control columella differ, and since the control columella is set by the sharp instrument to the state before the power outage, there is no need to use a latching relay, and the shape can be made smaller and cheaper.
