In addition, a notification unit is provided in the device monitoring control system, so that the notification unit can grasp predetermined information monitored by the device monitoring control system around the device monitoring control system without using a client terminal. It is possible.

FIG. 2 shows a block structure diagram of the device monitoring control system 1. A communication unit 101 includes a terminal unit for connecting the network 2. In the present embodiment, since communication is performed using the Ethernet (TM) standard of IEEE 802.3, which is a general standard, a terminal whose connector shape matches RJ45 is used. In addition to the method of connecting the network directly by connecting a cable to the network terminal, the network connection terminal portion may be wirelessly connected to the network wirelessly. In addition to the Ethernet standard, communication may be performed using, for example, the FDDI or Token Ring method. The device monitoring control system 1 is first connected to a LAN, and a modem or router serving as an Internet connection means for connecting to the Internet network is provided in a part of the LAN, and performs communication with the Internet side.

Further, as a form of direct connection to the Internet, not via a LAN, a modem may be connected to the communication means 101 as an Internet connection means, and a global IP address may be assigned and used.

Reference numeral 102 denotes calculation means. The arithmetic means 102 is for performing execution processing of various software, which will be described later, and for input / output control of input signals and output signals from connected devices, and is configured using a central processing processor (CPU). A storage unit 103 is connected to the calculation unit 102 and includes a memory in which data is written and read according to a request from the calculation unit 102. The storage means 103 stores current consumption data of various software and electrical devices, and software and data are read and written as needed.

Next, the terminal part which connects an electric equipment is demonstrated.

Reference numeral 104 denotes an HA terminal (JEM-A terminal defined by the Japan Electrical Manufacturers' Association) for connecting and controlling HA (home automation) equipment.

Reference numeral 105 denotes an analog signal input terminal for connecting various electric devices, in particular, sensor devices and receiving sensor inputs, and 105 'is also a digital signal input terminal. The sensor uses a sensor whose sensor output becomes a high or low signal, such as a gas sensor, a heat / smoke sensor, a mechanical switch that generates an ON-OFF signal, or an electronic switch, and obtains an output signal from the sensor or switch. It is also possible to input sensors such as thermistors and current transformers whose sensor output increases or decreases in an analog fashion.

Reference numeral 107 denotes a connection terminal that is connected to an electric machine or component that operates with direct current or alternating current. The connection terminal 107 is connected to the power input unit 109 via the relay 106. The control signal input unit of the relay 106 is connected to the calculation unit 102, is driven by receiving a control signal from the calculation unit 102, and electrically connects and disconnects the power input unit 109 and the connection terminal 107, thereby the relay 106. The power is supplied to the secondary side, that is, the electromechanical equipment and components connected to the connection terminal 107.

Further, on the secondary side of the relay 106, whether or not the connected electrical device is operating is determined by the operation state confirmation unit 108. This is determined by measuring whether the voltage value between the secondary terminals of the relay 106 is equal to the applied voltage of the power input unit 109 or zero potential. Specifically, a voltage dividing resistor is provided between the secondary terminals of the relay 106, and the potentials at both ends of the voltage dividing resistor are measured. That is, the voltage value between the secondary side terminals is zero potential when power is supplied to the electrical equipment, and the secondary side terminals are not supplied when power is not supplied to the electrical equipment. The voltage value becomes equal to the applied voltage of the power input unit 109. The output of the operation state confirmation unit 108 is input to the calculation means 102.

For devices connected to the HA terminal, the operation status is determined using a control signal for operating / stopping the device specified in the JEM-A standard and a feedback signal indicating the operation status of the device. To determine the operating state.

The HA terminal 104, the contact input terminal 105, and the connection terminal 107 are connected to the calculation means 102 via an operation state confirmation unit connected to the relay 106, and the calculation means 102 passes through the terminals. To obtain information data on connected devices and control the devices. As an alternative to the relay 106, for example, an SSR that is driven by receiving a control signal from the computing means 102 may be used.

Reference numeral 109 denotes a power input unit. This is an input for supplying power to the equipment monitoring control system 1, and is used by connecting to an AC power source or a DC power source. The power input unit 109 is connected to an in-terminal DC power source 109 ′ that generates a DC power source suitable for the device monitoring control system 1 by AC-DC converting means or DC-DC converting means. The driving power is supplied to the computing means 102, the storage means 103, and the like constituting the computer. Since the power input unit 109 is used by being connected to the DC power supply 109 ′ within the terminal and the relay 106, for example, the required voltage of the connected device operated by driving the relay 106 is the allowable voltage of the DC power supply 109 ′ within the terminal. In order to cope with the above case, that is, when it is desired to connect two types of input power sources, two input terminals of the power input unit 109 may be provided. In this case, the power supply for the connection terminal 107 is configured separately from the power supply path for the in-terminal DC power supply 109 ′ so as to be directly supplied to the relay 106.

Reference numeral 110 denotes a current monitoring unit, which includes a current transformer (CT). The output of the current transformer 110 is amplified by the current detection unit 111 to which the current transformer 110 is connected, and further input to the computing means 102. The current transformer 110 is mounted and used so as to penetrate the electric wire of the electric circuit whose current is to be measured. The current transformer may be a split type or a non-split type. The current detection unit 111 is configured to amplify an output signal from the current transformer using an operational amplifier and input the amplified signal to the calculation means.

Reference numeral 112 denotes a wireless communication unit. The wireless communication unit 112 performs wireless communication with a notification unit 113 (to be described later), outputs predetermined information of the device monitoring control system 1 to the notification unit 113, and displays and issues the predetermined information at the notification unit. It can be done to the surroundings.

In addition, the wireless communication unit 112 includes communication means based on the short-range wireless communication standard using IEEE 802.15.4 defined by IEEE as a physical interface, and performs communication corresponding to the ZigBee standard as a wireless sensor group. And do. As a result, it is possible to receive predetermined information issued by various wireless sensors, transmit information to a specific sensor and transmit a determined process, and perform bidirectional communication. For example, by using a human sensor as a sensor and preparing in the vicinity of the control target device, information on whether or not there is a person in the vicinity of the control target device is acquired, and there are two situations where a person is present or absent. The operation may be performed to change the control method accordingly.

The monitoring current level setting means 114 sets the magnitude of the current to be monitored, and uses a rotary switch. The monitoring current level setting means 114 is configured so that a plurality of monitoring current levels can be set manually and alternatively. Is input to the calculation means 102. The monitoring current level can be set to 20A, 30A, 40A, 50A, and 60A. The equipment monitoring control system 1 monitors the state of the energization current in the monitored electric circuit with reference to the monitoring current level determined by the monitoring current level setting means 114. The monitoring current level may be set so that other values can be set or can be set steplessly. In general, the rated current of the main breaker or current limiter (limiter) provided in the distribution board provided in the electric circuit may be determined as a reference.

The calculating means 102 takes out a signal corresponding to the current value obtained from the current monitoring unit 110 and calculates and obtains the state of the energized current with respect to the monitoring current level determined by the monitoring current level setting means 114. A program used in the calculation is stored in advance in the storage unit 103, and is read out during the calculation to perform the calculation process.

Here, the state of the energization current with respect to the monitoring current level is a percentage of the current energization current with respect to the monitoring current level, and for the sake of simplicity, the percentage of the current energization method with respect to the monitoring current level is converted into a percentage. Is simply called a ratio. For example, when the monitoring current level is 20 A and the energization current is 12 A, the ratio of the current energization current to the monitoring current level is 60%. When the monitoring current level is 20 A and the conduction current is 22 A, the ratio of the current conduction current to the monitoring current level is 110%.

In addition, the current consumption of the electrical device is determined based on a change in the current flowing through the electrical path when the electrical device is controlled by the relay 106 or the HA 105. For example, when the ratio of the magnitude of the current flowing through the electric circuit to the value of the monitored current is 120% (72 A), when the electric current flowing through the electric circuit becomes 60 A by controlling the electric device, the calculation means 102 The consumption current of the electric device is calculated as 72A-60A = 12A and stored in the storage means 103. FIG. 102 shows an example of correspondence data stored in the storage unit 103 between the electrical equipment, the current consumption, and the order of control.

Next, the notification unit 113 will be described. The notification unit 113 is arranged around the device monitoring control system main body and performs wireless communication with the main body, thereby performing notification by displaying predetermined information, sound, or voice.

Power supply to the notification unit 113 is performed from a normal power outlet.

FIG. 4 shows an example in which the device monitoring control system 1 is applied in a dwelling unit. When connecting to an Internet network in a dwelling unit, various communication media such as wired and wireless are used, and various methods such as PPPoE, PPPoA, IPoA, DHCP, etc. are used for connection to an Internet service provider (ISP). However, FIG. 4 shows a connection form often used nowadays. First, the route connected to the network will be described. In the dwelling unit, the information terminal with control function 1 and the router 5 are connected by a LAN (local area network), and the router 5 and the modem 4 are connected by a communication line. Has been. Here, the modem 4 is a connection device for connecting to the ISP, and is used in any of PPPoE, PPPoA, IPoA, and DHCP. The router 5 can access the Internet from a plurality of network devices in the dwelling unit, and is provided with a HUB (hub) so that a plurality of network devices can be connected. Alternatively, the router 5 and the modem 4 may be integrated. Further, a camera 6 that can be connected to the network is connected to the router, and a human sensor 7 that senses the movement of a human or the like and outputs an output signal is connected to the camera 6.

The modem is connected to the network 2 (Internet network) via the ISP network, and the device monitoring control system 1 is connected from a client terminal 3 (computer, mobile phone, etc.) that can be connected to the Internet network outside the dwelling unit. Is possible.

The electric device 8 serving as a controlled device and the sensor 9 serving as a signal input device represent the HA device, various sensors, and various electric devices described above. Since the control function-equipped information terminal 1 is configured to be connected to the router 5, it is possible to easily install and install the device monitoring control system 1 in the existing Internet connection environment on the user side.

Moreover, the current monitoring unit 110 is provided in the power distribution board in the dwelling unit, and an output corresponding to the magnitude of the current flowing through the electric circuit is always output to the current detection unit 111.

Next, the flow in the case where the client terminal 3 accesses the device monitoring control system 1 via the network (Internet network) and controls the connected electrical devices will be described.

The storage unit 103 of the device monitoring control system 1 includes a web server that accepts an operation request from a client terminal, and an FTP server (file transfer protocol server) that receives a data file output from the network camera 6 and writes and stores it in the storage unit. A mail transmission program for transmitting mail to a predetermined mail address, a program for generating HTML data upon request of the web server, status data of connected devices, and user setting information data Has been.

Here, it is assumed that http://www.example.jp is used as a URL (Uniform Resource Locator) indicating a method of accessing the device monitoring control system 1. Note that the device monitoring control system 1 uses the DNS UPDATE standardized as RFC 2136 to dynamically associate the domain name used in the URL with the IP address assigned by the ISP. Is configured to do. Note that it does not matter if you use a normal DNS that has a fixed global IP address and is statically associated with the URL.

FIG. 5 is a flowchart showing the operation of the device. When the URL of the web server of the information terminal with control function 1 is accessed by the web browser installed in the client terminal 3 (step S1), the web server establishes an HTTP session after a predetermined calculation process, and the storage means The operation screen data is generated based on the status data of the currently connected device by the program stored in (1), and the operation screen data is transmitted to the client terminal 3 that is the access source (step S11).

The web browser of the client terminal 3 that has received the operation screen data displays the operation screen, and the user selects the operation device, selects the desired operation content, and transmits the device operation data to the web server (step). S2).

The web server that has received the device operation data extracts the operation target device and the operation content from the data, and recognizes the operation target device and the operation content (step S12). And the grasping | ascertainment process of the status data of the apparatus made into object is performed by a calculating means (step S13). If the previous operation content and the status data are appropriate, that is, if the operation content is content to turn on the device and the status of the control target device is OFF, an operation signal is output to the control target device. (Step S14). When the state change (OFF to ON) of the control target device is completed, the web server generates operation result screen data by a program and transmits the operation result screen data to the client terminal 3 (step S15).

The web browser of the client terminal 3 that has received the operation result screen data displays the operation result screen, and the user confirms the operation result (step S3).

FIG. 6 is a flowchart showing the flow of data browsing. Here, the network camera 6 is a camera connectable to the network described in FIG. When the human sensor 7 connected to the network camera 6 senses and outputs a human or the like and receives an output signal (step S31a), the camera shoots the video at that time (step S32a), generates a video data file, The data file is sent to the FTP server stored in the storage means of the information terminal with control function 1 determined in advance (step S33a).

The FTP server of the device monitoring control system 1 receives the data file (step S21a), writes the data in the storage means 103, and stores it (step S22a).

Next, when the URL of the web server of the device monitoring control system 1 is accessed by the web browser installed in the client terminal 3 in order to display data (step S1a), the web server is stored in the storage means by the program. While searching the data file, list display screen data showing a list of data obtained as a result of the search is generated and transmitted to the client terminal 3 (step S11a).

The web browser of the client terminal 3 that has received the list display screen data displays the list display screen, and when the data to be displayed is selected by the user, the data selection request data is transmitted to the web server (step S2a). .

When receiving the selection request data (step S12a), the web server reads the target data file from the storage means (step S13a), and transmits the target data file to the client terminal 3 (step S14a). The web browser of the client terminal 3 that has received the data file displays the selected data file, and the user can view the desired video data (step S3a). Not only the current image but also the past data stored in the storage means, for example, the state of the device several hours ago or several days ago, the video data of the camera, etc. can be read and displayed by the program or displayed. The user can refer to it more conveniently.

Further, when a pyroelectric sensor is used as the sensor 7 and a human sensor is used as the sensor 9, when the human sensor reacts, the electric device 8 (for example, television, lighting, etc.) is driven and the brightness is reduced. When the pyroelectric sensor 7 connected to the camera is driven by the change, the camera 6 captures the surroundings, and the image obtained by the camera 6 is transferred to the device monitoring control system 1 and stored in the storage means. The device monitoring control system 1 transmits an e-mail addressed to a predetermined e-mail address, and the client terminal that receives the e-mail can grasp the state of the dwelling unit via the e-mail.

FIG. 7 is a flowchart showing a flow of sending a mail to a predetermined mail address by driving a predetermined electric device when the state of the device connected to the device monitoring control system 1 is changed. A case will be described in which a temperature sensor is used as the connection device, and a ventilation fan connected to the relay 106 and an air conditioner connected to the HA terminal 104 are used as predetermined electrical devices.

When the connected temperature sensor operates (step S21b), the calculation means 102 of the device monitoring control system 1 receives the operation signal (step S11b), and reads a predetermined program stored in the storage means 103 (step S111b). Then, a predetermined electrical device is driven based on the program (step S112b), and the mail transmission program stored in the storage means 103 is read and activated (step S12b).

The predetermined electric device is driven by sending a control signal from the computing means 102 to the HA terminal, or sending a control signal to the relay 106 to supply power to the electric device connected to the secondary side. Do by doing.

The calculation means 102 is directed to a preset e-mail address, and a predetermined e-mail text stored as user setting data in the storage means, for example, “Temperature sensor has been activated. The URL is http://www.example.net/sensor/cond ", and is transmitted after adding the mail body (step S13b).

When the client terminal 3 receives the mail (step S1b), the user confirms the mail (step S2b) and accesses a predetermined URL (step S3b). When the web server receives the access from the client terminal 3, the web server reads the program, collects the corresponding data file and the data of the operated device, generates the confirmation screen data of the operated device, and sends it to the client terminal 3. The confirmation screen data is transmitted to the destination (step S14b).

When the client terminal 3 receives the confirmation screen data of the operated device, the web browser displays an image and a confirmation screen of the operated device (step S4b), and the user can check the operated device. In this way, if the e-mail address is set to the e-mail address used by the user, when the operating status of the connected device changes, the change is voluntarily notified by sending an e-mail. Therefore, it is possible to provide an information terminal with a control function that is easier to use.

In addition, when the sensor is driven by inputting the contact output output from the computing means 102 of the device monitoring control system 1 to the network camera 6 having an external contact input terminal using illumination as an electrical device. By turning on the light and shooting the surroundings with the camera, the captured data is attached to the e-mail as an attached file, or linked to the URL described in the e-mail so that the user can visually see the state when the sensor is operating Can be recognized. Further, by accumulating image data in the storage means 103, it is possible to implement various combinations according to the use assumed by the user, such as browsing the history retroactively.

In this flowchart, the sensor is used as the connection device to the contact input terminal 105. However, in the case where the non-voltage contact device 1053 is used as the connection device, for example, as the non-voltage contact device, When a hand open / close switch or the like that opens or closes the circuit by an a contact or a b contact is used, when the hand open / close switch is turned on / off, the contact output is received by the computing means 102, and the computing means 102 can be configured to start a mail transmission program stored in the storage means 103 and to transmit a mail to a predetermined mail address. That is, in addition to automatic mail transmission by a sensor or the like, mail can be transmitted by manual input, and mail can be intentionally transmitted when mail transmission is desired.

Next, the operation of current monitoring will be described. The description will be made assuming that there are four electric devices (A81, B82, C83, D84) to be controlled.

First, the step of collecting the current consumption of each electric device will be described with reference to FIG.

In the device control system 1, the monitoring current level setting unit 114 is operated to set the current level to be monitored (step S001).
Next, for each electrical device, a temporary control order is determined by the calculation means (step 002). FIG. 103 shows stored data in which a provisional control order is determined, and the electrical equipment A81, the electrical equipment B82, the electrical equipment C83, and the electrical equipment D84 are provisionally determined in order from the earliest control order.

When the provisional control order is determined, information on the current consumption of each electrical device is collected next. Each electric device is operated, the change in the current flowing in the electric circuit is measured, and stored in the storage means.

The calculation means 102 first checks whether there is consumption current data in the storage means for the electric device A81 (step S003), and if not, performs operation control of the electric device A81 (step S0031) and changes the current flowing in the electric circuit. The amount is measured (step S0032), and the amount of change in the current is stored in the storage means as consumption current data (step S0033). If current consumption data already exists in the storage means, the process proceeds to the next step (step S004).

Next, the calculation means 102 checks whether or not there is current consumption data in the storage means for the electric device B82 (step S004), and if not, performs operation control of the electric device B82 (step S0041), and the current flowing in the electric circuit Is measured (step S0042), and the current variation is stored in the storage means as consumption current data (step S0043). If current consumption data already exists in the storage means, the process proceeds to the next step (step S005).

Next, the calculation means 102 checks whether or not there is current consumption data in the storage means for the electric device C83 (step S005), and if not, performs operation control of the electric device C83 (step S0051), and the current flowing in the electric circuit Is measured (step S0052), and the current variation is stored in the storage means as consumption current data (step S0053). If current consumption data already exists in the storage means, the process proceeds to the next step (step S006).

Next, the computing means 102 checks whether or not there is consumption current data in the storage means for the electric device D84 (step S006). If not, the operation means 102 controls the operation of the electric device D84 (step S0061), and the current flowing in the electric circuit Is measured (step S0062), and the current variation is stored in the storage means as consumption current data (step S0063). If current consumption data already exists in the storage means, the process proceeds to the next step (step S007).
FIG. 104 shows an example of stored data in which current consumption data for each electrical device obtained from step S003 to step S006 is stored.

When the current consumption data of all the electric devices A81 to D84 is collected, the control order is rearranged based on the size of the current consumption data. That is, as shown in FIG. 105, the electric device D84 (12A), the electric device A81 (10A), the electric device C83 (6A), and the electric device B82 (3A) are rearranged from the earliest control order.

This makes it possible to control electrical devices with priorities that match the actual usage conditions, compared to when the priorities of the electrical devices to be controlled are fixed, and more efficiently prevent power outages. Will be able to do. In addition, since the user's side sets the priority order of the electric devices that the device monitoring control system 1 controls so as to conform to the actual usage state, it is possible to leave the setting without worrying about the control. In addition, it can be seen that controlling the use of certain electrical equipment increases or decreases the current usage rate, leading to an increase in energy conservation awareness.

Further, the current consumption data of the electric equipment may be provided so as to be stored separately for the change amount of the current flowing through the electric circuit when the electric device starts operation and the change amount of the current flowing through the electric circuit when the operation is stopped. . That is, in the steps S003, S004, S005, and S006, when the current consumption is checked, both the control for starting the operation of the electric device and the control for stopping the operation are performed, and the change in the current in the electric circuit accompanying the start of the operation is performed. Measure the amount and the amount of change in current as the operation stops.

This takes into account the fact that the current consumption at the start of operation of electrical equipment may differ from the current consumption at the time of shutdown. For example, when floor heating equipment is used as electrical equipment, the current consumption is Although it is almost constant at the start and throughout the steady state, when using an air conditioner as an electrical device, a large amount of current is consumed at the start of operation in order to quickly approach the set temperature, and the current consumption in the steady state is greater than at the start of operation. When the operation control of an electric device is performed so that the current flowing in the electric circuit is reduced to prevent a total power failure, the electric device that consumes a large amount of current when the operation is stopped. This is because it is possible to efficiently prevent all blackouts by controlling a smaller number of electrical devices by giving priority to control.

In addition, when controlling the operation of electrical equipment so that the current flowing in the circuit increases, control the electrical equipment that consumes less current at the start of operation with priority, so that there is no risk of a total power failure. This is because a larger number of electric devices can be used in the range, and it is possible to perform highly convenient control.

FIG. 106 shows electric data, the amount of change in current in the electric circuit associated with the start of operation, the amount of change in current associated with the stop of operation, and stored data that stores the control order. When controlling electrical equipment in a direction that reduces the current flowing in the electrical circuit,
Electrical equipment D84 (12A)
Electrical equipment A81 (10A)
Electric equipment C83 (6A)
Electric equipment B82 (3A)
Therefore, when controlling electrical equipment in the direction that increases the current flowing in the circuit,
Electric equipment B82 (5A)
Electrical equipment A81 (10A)
Electrical equipment C83 (12A)
Electrical equipment D84 (15A)
The operation is controlled so that

Although the case where the number of electrical devices is four is shown, an arbitrary number of electrical devices can be controlled by sequentially adding or deleting steps according to the increase or decrease of the number of electrical devices.

In the examples shown so far, the priority control order of the electric devices A81 to D84 is determined by the device monitoring control system 1, but in some cases, the user does not want to control a specific electric device as much as possible. Or, if it is a specific electrical device, the case where you want to control first is assumed. For this reason, an item for fixing the order may be provided in the stored data so as to fix the control order for a specific electric device or a plurality of electric devices.

FIG. 107 shows an example of stored data provided with items for fixing the control order. The user accesses the web server of the device monitoring control system 1 from the operation terminal 4 or the operation terminal 7, receives provision of predetermined operation screen data, selects an electric device whose control order is to be fixed, and controls the control. Enter the order. The input data is transmitted to the web server. When the input data is received on the web server side, the stored data stored in the consumption current storage means 103 is corrected by a predetermined program. For example, when the input data from the operation terminal wants to make the order of stopping the operation last for the electric device A81, as shown in FIG. 107, the operation stop order of the electric device A81 is set to the fourth and fixed. Check the column (store it as locked), correct the stored data, and reorder the remaining three electrical devices that are not fixed in order in the order of the current consumption data when the operation is stopped. In other words, when controlling electrical equipment in a direction that reduces the current flowing in the circuit,
Electrical equipment D84 (12A)
Electric equipment C83 (6A)
Electric equipment B82 (3A)
Electrical equipment A81 (10A) (fixed order)
Modify to be.
In addition, when it is desired to start the operation for the electric device A81 first, the operation start order of the electric device A81 is set to the first, and the fixed column is checked (stores that there is a lock) and stored. In addition to correcting the data, the remaining three electrical devices that are not fixed in order are sorted again in ascending order of the current consumption data at the start of operation. In other words, when controlling electrical equipment in the direction that increases the current flowing in the circuit,
Electrical equipment A81 (10A) (fixed order)
Electrical equipment C83 (3A)
Electric equipment B82 (5A)
Electrical equipment D84 (15A)
Modify to be.

In addition, in order to collect the consumption current data of the electric equipment, the method of operating the electric equipment once by the calculation means at the time of setting and measuring the current flowing in the electric circuit before and after that was shown. After the provisional control order is established, if there is a possibility of a total power failure, the electrical equipment is controlled based on the provisional control order, and the current flowing through the electrical circuit before and after the controlled electrical equipment is controlled. You may provide so that it may control using the method of collecting the consumption current data of the electric equipment by measuring. In this case, there is a convenience that the number of steps can be reduced because it is not necessary to operate the electric devices once in order.

Further, these stored data are updated each time the operation control of each electric device is performed. For example, when the operation control of the electric device A81 is performed, the amount of change in the current flowing through the electric circuit before and after the operation control is measured is measured, and the consumption current data of the electric device A81 stored in advance and the new data are newly stored. The average value of the measured current consumption data is calculated by the calculation means 104, corrected to the stored data, and stored. As a result, by continuing to use the device control device, the current consumption data of the electrical device is averaged, thereby reducing the contribution of errors and the like, and enabling accurate control.

Now, when the control order of the electric equipment to be controlled is determined, the process proceeds to step S201 for monitoring the current flowing in the electric circuit as shown in FIG. When a signal corresponding to the energization current (inductive current generated in CT) is input from the current monitoring unit 110 to the current detection unit 111 and input to the calculation unit 102 (step S202), the calculation unit 102 is stored in the storage unit. Based on a predetermined program stored in 103, the ratio of the energization current to the monitoring current level is calculated (step S203). For example, when the monitoring current level is 20 A and the energization current is 12 A, the ratio of the current energization current to the monitoring current level is 60%.

Next, the calculation means 102 stores the classification data that is stored in the storage unit 103 in advance and classifies the current use ratio in advance in a predetermined class, in this embodiment, less than 20%, 20% or more and less than 40%, 40%. 9 categories are set: over 60%, under 60% and under 80%, over 80% and under 100%, over 100% and under 110%, over 110% and under 120%, over 120% and under 140%, over 140% However, from these, calculation is performed as to which category the ratio obtained in step S203 corresponds to, and corresponding category data is extracted (step S204).

For example,
Classification data: 0 = less than 20% Classification data: 1 = 20% or more and less than 40% Classification data: 2 = 40% or more and less than 60% Classification data: 3 = 60% or more and less than 80% Classification data: 4 = 80% or more and 100 Less than% classification data: 5 = 100% or more and less than 110% Classification data: 6 = 110% or more and less than 120% Classification data: 7 = 120% or more and less than 140% Classification data: 8 = 140% or more Are associated with each other. If the ratio calculated in step S203 is 60%, the corresponding classification data is “3”.

Next, the computing means 102 outputs the classification data “3” obtained in step S204 to the wireless communication means 112 (step S205), and the wireless communication means outputs the classification data together with predetermined header information to the notification unit 113. Make a radio call.

In addition, when current exceeding 100% of the set current is used, the operation of the circuit breaker or current limiter provided on the power distribution board will prevent the dwelling unit from undergoing a complete power failure. In the current use area where they may operate, the power supply to the electrical equipment connected to the equipment monitoring control system 1 is controlled.

When the ratio of current use calculated in step S203 is 110% or more and less than 120%, the power supply to the electrical equipment connected to the equipment monitoring control system 1 is stopped in 45 seconds. Specifically, the calculation means 102 counts the number of seconds in which the division data is “6”, and notifies the notification unit 113 that “electricity is being used excessively” every 10 seconds (details will be described later). Then, after 40 seconds have elapsed, the notification unit 113 is also informed that “the supply of power will be stopped soon”, and after 45 seconds have elapsed, the supply of power is stopped and “the supply of power has been stopped” is notified. Note that in the case of 100% or more and less than 110%, the notification unit 113 only notifies that “too much electricity is used” every 180 seconds. This is a current usage area that may take several tens of minutes to several hours for the circuit breaker to operate for the purpose of wiring protection, so the user is informed that they are using too much electricity. It only encourages restraint.

Next, when the ratio of current use calculated in step S203 is 120% or more and less than 140%, the power supply to the electrical equipment connected to the equipment monitoring control system 1 is stopped in 15 seconds. Specifically, the calculation means 102 counts the number of seconds where the division data is “7” and causes the notification unit 113 to notify that “electricity is being used excessively” every 5 seconds (details will be described later). . Then, after 10 seconds elapse, the notification unit 113 is also notified of “soon to stop supplying power”, and after 15 seconds elapses, the power supply is stopped and “power supply stopped” is notified. In addition, you may change suitably the waiting time in the case of these alerting | reporting, and the waiting time until it stops.

Next, when the current usage ratio calculated in step S203 is 140% or more, the circuit breaker operation start time is performed earlier for wiring protection. Is stopped to notify that “the power supply has been stopped”.

The current monitoring unit 110 is mounted so as to pass through the electric circuit (secondary side of the main switch) in the power distribution board, but how much current is used in the dwelling unit with respect to the set current. For the purpose of grasping the ratio, it may be used by attaching to the secondary side of a specific branch switch.

In addition, when changing the circuit to be monitored from the circuit on the main switch side to the circuit on the branch switch side, the rotary switch of the monitoring current level setting means is branched and opened along with the removal of the split CT. It is necessary to set the current value to match the rated current of the vessel. For example, the main switch normally has a rated current of about 60 A, but the branch switch often has a smaller current than the main switch, for example, a rated current of about 20 A.

Next, the stage in which the appliance monitoring control system 1 controls the electrical equipment will be described with reference to FIGS. In particular, the flow for stopping and starting the operation of electrical equipment will be explained.

Here, there are four electric devices to be controlled, and when controlling the start of operation of electric devices in a direction that reduces the current flowing in the electric circuit,
Electrical equipment D84 (12A)
Electrical equipment A81 (10A)
Electric equipment C83 (6A)
Electric equipment B82 (3A)
age,
When controlling the start of operation of electrical equipment in the direction that increases the current flowing in the electric circuit,
Electric equipment B82 (5A)
Electrical equipment A81 (10A)
Electrical equipment C83 (12A)
Electrical equipment D84 (15A)
The operation is controlled so that The case where a current limiter is provided on the distribution board will be described.

First, when the device monitoring control system 1 starts current monitoring (step S301), the calculation means calculates whether the ratio exceeds 100% (step S302), and if it exceeds, waits for a predetermined time. (Step S303), if not, the process returns to Step S301 to continue the process. The purpose of waiting for a predetermined time is not instantaneous, but is to determine whether or not it exceeds 100% continuously for a predetermined time to prevent erroneous control. As described above, the predetermined time is 45 seconds if it is less than 120%, 15 seconds if it is 120% or more and less than 140%, and 140% or more if it is less than 120%. Is set in advance to be 2 seconds.

After waiting for a predetermined time, it is further calculated whether the ratio exceeds 100% (step S304), and if so, the order of control in the case of controlling the electrical equipment in the direction of reducing the current flowing in the electric circuit is The operation of the early electric device is stopped (step S305). Note that the change in the current flowing through the electric circuit when the operation of the electric device is stopped is measured (step S3051), and is stored in the storage means as consumption current data accompanying the operation stop.

Next, it is calculated whether the ratio exceeds 100% (step S306). If not, it is calculated whether it is equal to or less than the return current (step S307). The process proceeds to S401 (described later). Note that the return current is a predetermined value that has a margin with respect to the monitoring set current, and serves as an index for starting the operation again after stopping the operation. .

Here, the return current will be briefly described. If the ratio falls below 100%, falls below a preset return current, and 60 seconds have passed, the electric equipment that has been stopped is restored. The magnitude of the return current depends on the magnitude of the set current.
10A for a set current of 20A,
21A for a set current of 30A,
32A for a set current of 40A,
42A for a set current of 50A,
52A for a set current of 60A,
It is defined as.

In step S307, if the current flowing in the electric circuit is below the return current, the process waits for a predetermined time (step S308), and after the predetermined time has passed, the calculation is performed again to determine whether the current is below the return current (step S309). ), When the current is lower than the return current, the control is performed so as to start the operation of the first electric device (that is, the electric device whose operation is stopped in step S305) in the control order (step S310). At this time, the change in the current flowing through the electric circuit when the operation of the electric device is started is measured (step S3101), and the current consumption data accompanying the start of operation is stored in the storage means. Then, after performing control so as to start the operation of the electric device with the first control order, the process returns to step S301 and continues to monitor current.

In step S306, if the ratio exceeds 100%, the process proceeds to step S401, and the control preparation stage of the second electrical device whose control order is the second is entered.

If the ratio exceeds 100% in step S306, it waits for a predetermined time (step S401), and after waiting for the predetermined time, calculates whether the ratio exceeds 100% (step S402) and exceeds it. In such a case, the operation of the second electric device in the control order when the electric device is controlled in a direction to reduce the current flowing in the electric circuit is stopped (step S403). Note that the change in the current flowing through the electric circuit when the operation of the electric device is stopped is measured (step S4031), and is stored in the storage means as consumption current data accompanying the operation stop. If it is determined in step S402 that the ratio does not exceed 100%, the process proceeds to step S307 to calculate whether the current is equal to or less than the return current.

Next, it is calculated whether the ratio exceeds 100% (step S404), and if not, it is calculated whether it is equal to or less than the return current (step S405). The process proceeds to S501 (described later). The return current is as described above.

In step S405, if the current flowing in the electric circuit is lower than the return current, the process waits for a predetermined time (step S406). After the predetermined time, the calculation is performed again to determine whether the current is lower than the return current (step S407). ), If the current is lower than the return current, the control order data at the start of operation of the first and second electric devices in the control order is compared and calculated (step S408), and the first and second electric orders in the control order are compared. Among the devices, the start control of the operation of the electric device having the earlier control order data at the start of operation is performed (step S409). Here, the control order of the electrical equipment when the operation is stopped and the control order of the electrical equipment when the operation is started do not necessarily match as shown in FIG.

Next, it is calculated whether or not the ratio exceeds 100% (step S410), and if it does not exceed, it waits for a predetermined time (step S411), and if it exceeds, the process returns to step S401 to continue the processing.

After waiting for a predetermined time in step 411, it is calculated whether the current flowing in the electric circuit is equal to or less than the return current (step S412). If it is equal to or less than the return current, the step of starting the operation of the other electrical device ( The process proceeds to step S310), and if it is not equal to or less than the return current, the process returns to the step of calculating the ratio (step S410) and the processing is continued.

In step S404, if the ratio exceeds 100%, the process proceeds to step S501, and the control preparation stage of the third electrical device having the control order is entered.

If the ratio exceeds 100% in step S404, it waits for a predetermined time (step S501), and after waiting for the predetermined time, calculates whether the ratio exceeds 100% (step S502) and exceeds it. In this case, the operation of the third electric device in the control order when the electric device is controlled in a direction to reduce the current flowing in the electric circuit is stopped (step S503). Note that the change in the current flowing through the electric circuit when the operation of the electric device is stopped is measured (step S5031), and stored in the storage means as current consumption data accompanying the operation stop. If it is determined in step S502 that the ratio does not exceed 100%, the process proceeds to step S405 to calculate whether the current is equal to or less than the return current.

Next, it is calculated whether the ratio exceeds 100% (step S504), and if not, it is calculated whether it is equal to or less than the return current (step S505). The process proceeds to S601 (described later). The return current is as described above.

In step S505, if the current flowing in the electric circuit is lower than the return current, the process waits for a predetermined time (step 506), and after the predetermined time has passed, calculation is performed again to determine whether the current is lower than the return current (step S507). ), If it is below the return current,
The control order data at the start of operation of the first, second, and third electric devices is compared and calculated (step S508), and the operation starts among the first, second, and third electric devices. The operation of the electric device with the earlier control order data is controlled to start (step S509). Here, the control order of the electrical equipment when the operation is stopped and the control order of the electrical equipment when the operation is started do not necessarily match as shown in FIG.

Next, it is calculated whether or not the ratio exceeds 100% (step S510), and if it does not exceed, it waits for a predetermined time (step S511), and if it exceeds, the process returns to step S501 to continue the processing.

After waiting for a predetermined time in step S511, it is calculated whether or not the current flowing in the electric circuit is equal to or less than the return current (step S512). The process proceeds to the starting step (step S409), and if it is not equal to or less than the return current, the process returns to the step of calculating the ratio (step S510) to continue the processing.

If the ratio exceeds 100% in step S504, the process waits for a predetermined time (step S601), and after waiting for the predetermined time, calculates whether the ratio exceeds 100% (step S602). If so, the operation of the third electrical device in the order of control when the electrical device is controlled in a direction to reduce the current flowing in the electric circuit is stopped (step S603). Note that the change in the current flowing through the electric circuit when the operation of the electric device is stopped is measured (step S6031), and stored in the storage means as consumption current data accompanying the operation stop. If it is determined in step S602 that the ratio does not exceed 100%, the process proceeds to step S605 to calculate whether the current is equal to or less than the return current.

Next, it is calculated whether the ratio exceeds 100% (step S604). If not, it is calculated whether it is equal to or less than the return current (step S605). The process proceeds to S6041 and waits for a predetermined time. After waiting for a predetermined time, the process returns to step S604 and continues. Here, when the ratio still exceeds 100% in step S604, the device control apparatus performs control to stop the operation for all controllable electric devices, so that the user manually Reduce the amount of current in the electric circuit by stopping the operation of other electrical equipment. When the state where the ratio exceeds 100% continues, there is a possibility that a total power failure occurs. The return current is as described above.

In step S605, if the current flowing in the electric circuit is less than the return current, the process waits for a predetermined time (step 606). After the predetermined time, the calculation is performed again to determine whether the current is lower than the return current (step S607). ), When the current is lower than the return current, the control order data at the start of operation of the first, second, third and fourth electric devices is compared and calculated (step S608). Among the second, third, and fourth electric devices, the operation of the electric device with the earlier control order data at the start of operation is controlled to start (step S609). Here, the control order of the electrical equipment when the operation is stopped and the control order of the electrical equipment when the operation is started do not necessarily match as shown in FIG.

Next, it is calculated whether or not the ratio exceeds 100% (step S610), and if it does not exceed, it waits for a predetermined time (step S611), and if it exceeds, the process returns to step S601 to continue the processing.

After waiting for a predetermined time in step S611, it is calculated whether or not the current flowing through the electric circuit is equal to or less than the return current (step S612). The process proceeds to the start step (step S509), and if it is not equal to or less than the return current, the process returns to the step of calculating the ratio (step S610) to continue the processing.

By controlling in this way, it is possible to reduce the inconvenience caused by the inability to use electrical equipment for the user as much as possible while preventing all blackouts in the dwelling unit.

Next, the notification unit 113 will be described. The operation of the notification unit 113 will be described in the following manner. The notification unit 113 receives a radio signal (classification data) from the main body of the device monitoring control system 1 via the antenna unit 1139 by the radio transmission / reception unit 1131 and then a predetermined process (display unit) corresponding to the classification data by the signal processing unit 1132. Display to 1133, output to alarm generation unit 1134, etc.) (operation specifications will be described later).

The display unit 1133 includes a plurality of LEDs, and displays a ratio (%) of the current use current with respect to the monitoring current level in a stepwise light emission manner, and visually displays margin information such as how much current can be used. In this embodiment, the display unit 703 uses six LEDs to display the current usage state. When the LEDs are L1, L2, L3, L4, L5 and L6, respectively,
L1 lights up when the ratio of energization current is less than 20%.
L2 lights up when the ratio of energization current is 20% or more and less than 40%.
L3 lights up when the ratio of energization current is 40% or more and less than 60%.
L4 lights up when the ratio of energization current is 60% or more and less than 80%.
L5 lights up when the ratio of energization current is 80% or more and less than 100%.
L6 lights up when the ratio of the energization current is 100% or more.
As the amount of current used increases, the number of lights is increased step by step so that the level can be displayed.

The alarm generating unit 1134 is for generating a predetermined alarm (sound / voice), and uses a small speaker. A sound alarm is generated in response to an instruction from the signal processing unit 1132 in accordance with the ratio of the energization current in the monitoring circuit. When the ratio of the energizing current is 100% or more, the LED emits light, and according to the ratio exceeding 100%, the sound generator will “use too much electricity”, “turn off the power soon”, Notifications such as “Power off”, “Power restored”, “I can use electricity”, etc. are made.

The cordless handset is provided with a power plug 1135 that can be plugged into an outlet so that it can be carried freely according to the user's location, so that it can be used at the location of the outlet. At this time, means for displaying whether or not the radio signal has arrived so that the user can easily grasp whether or not the radio signal transmitted from the device monitoring control system 1 can be properly received is displayed on the LED of the display unit 1133. Is provided.

In this embodiment, L1 is provided with this function, and when L1 is less than 20% of the energization current to the monitoring current level, the main body is operating and radio signals can be received appropriately. In case it comes to light up. That is, this LED is always lit while the main body is operating normally.

When the reception sensitivity is good due to the processing of the signal processing unit 1132, the LED is always lit. However, when the reception sensitivity is not appropriate, the LED is blinked to indicate that the reception sensitivity is not good. Show. That is, when the lowest LED among the LEDs of the information display unit 1133 is blinking, this means that a wireless signal has not been received.

In use, if the lowermost LED of the notification unit 113 is continuously lit, it has a function of easily recognizing that the radio signal from the device monitoring control system 1 can be satisfactorily received. When it is blinking, it is moved to an outlet that can receive radio signals appropriately so that the LEDs are continuously lit.

Next, the operation of the LED of the display unit 1133 and the alarm generation unit (speaker unit) 1134 will be described.

The signal processing unit 1132 controls the turning on / off of the LEDs as described below according to the classification data received from the device monitoring control system 1.

When section data 0 is received, only L1 is turned on. This indicates that the proportion is less than 20%.
When the classification data 1 is received, L1 and L2 are turned on. This indicates that the ratio is 20% or more and less than 40%.
When division data 2 is received, L1, L2, and L3 are turned on. This indicates that the ratio is 40% or more and less than 60%.
When the classification data 3 is received, L1, L2, L3, and L4 are turned on. This indicates that the ratio is 60% or more and less than 80%.
When the division data 4 is received, L1, L2, L3, L4, and L5 are turned on. This indicates that the ratio is 80% or more and less than 100%.
When the classification data 5 is received, all of L1, L2, L3, L4, L5 and L6 are turned on. In this case, the ratio is 100% or more and less than 110%.
When the classification data 6 is received, all of L1, L2, L3, L4, L5 and L6 are turned on. In this case, the ratio is 110% or more and less than 120%.
When the classification data 7 and 8 are received, all of L1, L2, L3, L4, L5 and L6 are turned on. In this case, the ratio is 120% or more.

When the classification data 4 or less is received, that is, when the ratio is less than 100%, the signal processing unit 1132 does not control the alarm generation unit 1134. When the classification data 5 or more is received, that is, when the ratio is 100% or more, the alarm generation unit 1134 is controlled to generate an alarm.

Next, the case where the ratio is 100% or more will be described.

When the ratio is 100% or more and less than 110%, a control signal for generating an alarm is sent at 180-second intervals to notify that “too much electricity is used”.

If the ratio is 110% or more and less than 120%, an alarm control signal is sent at 10-second intervals to notify that “too much electricity is being used” and that “the power will be turned off soon” after 40 seconds. Then, after 45 seconds, if the operation of the electrical equipment is stopped in step S305, it is notified that “the power has been turned off”. Further, when the operation of the electric device is stopped in steps S403, S503, and S603, the same notification is given.

When the ratio is 120% or more and less than 140%, a control signal for generating an alarm is sent every 5 seconds to notify that “too much electricity is used”, and after 10 seconds, “turn off the power soon”. , 15 seconds later, if the operation of the electrical equipment is stopped in step S305, the power is turned off. Further, when the operation of the electric device is stopped in steps S403, S503, and S603, the same notification is given.

In the case where the ratio is 140% or more, when the operation of the electric device is stopped in step S305 after 2 seconds, “power is turned off” is notified. Further, when the operation of the electric device is stopped in steps S403, S503, and S603, the same notification is given.

As described above, the signal processing unit 1132 performs LED lighting control and alarm generation unit 1134 control. When the current ratio is greater than 100%, the control section is subdivided. This is because the circuit switch operates with a certain time limit when the current usage is 100% or more. It is because it aims at reducing.

For example, the switch does not operate when the current ratio is 100%, but operates at several minutes to several hours when the current ratio reaches 120%, and operates at several tens of seconds to several minutes at 200%. If the electrical equipment is used further when the current ratio exceeds 100%, the switch operating time will be shortened rapidly. For the purpose of promoting the reduction of use and preventing all blackouts, the equipment monitoring control system 1 stops the supply of power to predetermined electrical equipment.

In addition, when a power supply to a predetermined electrical device is stopped, a program is provided to transmit the fact via an Internet network by e-mail, so that the user cannot recognize the notification of the notification unit 113. Even when you are in the office or going out, you can effectively recognize that there has been a change in the state of the dwelling unit.

A plurality of notification units 113 can be used. When using a plurality of notification units 113, if the classification data transmitted from the device monitoring control system 1 can be received, the information on the energization current can be displayed / alarmed. Just add the same ones.

Normally, when performing wireless communication, when there are a plurality of receiving destinations (clients) as viewed from the transmission source, when identifying the receiving destination, it is necessary to include an identification ID or the like in the wireless data. This complicates the communication protocol and increases the amount of data to be transferred, leading to increased costs such as measures to prevent interference.

In addition, it is necessary to set the receiving destination in advance in terms of software and hardware so that various identification IDs do not overlap, leading to an increase in cost.

However, since the device monitoring control system 1 transmits specific classification data from the device monitoring control system 1 and broadcasts it to the surroundings, a simple communication protocol, a small amount of transfer data, a plurality of data Wireless communication is possible without identifying the notification unit 113 of the table. Therefore, it is not necessary to set various IDs even in the slave unit, and it can be applied to the current monitoring device only by adding the same specification. However, when used in apartment houses such as apartments and condominiums, it is necessary to change the radio channel in order to distinguish it from the neighborhood.

By installing a plurality of notification units 113 and installing them in advance in a place where the user moves, it is possible to save time and effort to remove the notification unit 113 from the outlet each time the user moves around the room. Can do. In addition, even if the notification unit 113 is forgotten when moving, the display of the information on the energization current can be confirmed at the destination, and there is no possibility of missing the alarm when the alarm is issued.

As described above, according to the present invention, a device to be controlled does not require a retrofit unit such as a communication function or a monitoring unit, so that an increase in cost can be suppressed and a device monitoring control system is constructed. Can be managed easily without complications, and if the system is accessed or acquired from the system via the Internet and electricity is used excessively, the specified electrical equipment Convenient equipment monitoring and control system that can efficiently start the specified electrical equipment when it is ready to use, and can enhance monitoring and control and energy conservation awareness Can be provided.

Fig. 4 shows an example in which this equipment monitoring control system is applied to a house. In addition to acquiring information from various sensors and automatic control of electrical equipment, for example, it is linked with a door chime or an intercom. Then, when there is a visitor, the function of confirming that there was a visitor is transferred from the device monitoring control system 1 to the Internet and there is a visitor's client terminal. It may be configured.

In addition, by interlinking the main unit of the intercom connected to the chimes at the entrance and the like and the device monitoring control system 1, the information obtained from the main unit of the intercom is transmitted to the device monitoring control system 1. VoIP (Voice over Internet Protocol), which is a technology for exchanging voice information and call control in an IP network by means of arithmetic means provided in the equipment monitoring control system 1, or ITU- H.323 in the H.300 series, which is a standard for multimedia communications including voice and video, created by T (ITU Telecommunication Standardization Sector), and the internal organization of IETF (Internet Engineering Task Force) Mmusic WG (Multiparty Multimedia
In the IP network developed by the Session Control Working Group), the Internet uses SIP (Session Initiation Protocol), which is a session part control protocol for multiple users to perform multimedia communication using voice and video simultaneously. By converting to a format suitable for transmission to the network and communicating, it is possible to view conversations and videos with visitors at client terminals on the Internet side, and provide a more convenient device monitoring control system be able to.

Note that the interphone master unit and the device monitoring control system may be connected by, for example, a two-wire communication line.
