Description

The present invention relates to a technique for preventing a total power outage from occurring due to excessive use of electricity.

Conventionally, home monitoring with a power consumption monitoring function that prevents all load devices from operating unexpectedly when the current limiter or main breaker cuts off the power supply due to excessive use of electricity. A system (Patent Document 1) is known.

According to Patent Document 1 (FIG. 12), in order to prevent the current limiter or the main breaker from shutting off the power supply due to excessive use of electricity and preventing all the load devices from operating unexpectedly,
When the measured current amount does not decrease to a predetermined current amount after a predetermined time has elapsed after exceeding the preset alarm reference amount, relays R4 of the predetermined load devices 4 to 7 are used. ~ R7 is controlled so as to cut off the power supply (peak cut operation). As a result, it is possible to prevent the power supply to all the load devices from being interrupted all at once by the limiter 2B and the main breaker 2C.

Here, for the predetermined load devices 4 to 7, a priority order for cutting off the power supply is provided. If the current amount does not decrease, the power supply is cut off in order from the load device with the highest priority. It is configured. For example, the first priority order is the air conditioner 6 and the second priority is the hot water toilet seat 7, and this order is determined by the amount of electricity used by the load device and the importance with which the load device is used. It is.
When registering the priority order and the load device to be interlocked, a load interlock switch (not shown) of the operation setting unit 23 is operated, but the setting contents are stored in the storage unit 24 by a predetermined switch operation of the operation setting unit 23. It may be configured to be registered.

However, in the housing monitoring system having the power consumption monitoring function in Patent Document 1,
Since it is provided to operate a load interlock switch (not shown) of the operation setting unit 23 in order to set a load device that cuts off the power supply, it is manually set after the order of shutting off the power supply is determined in advance. There was a need to do. Also, when changing the order in which the power supply is cut off for some reason, it is necessary to go to the power distribution board and set it again by operating the load interlock switch in the operation setting unit. there were.
In addition, when the load device provided on the secondary side of the relay is replaced or changed, it is necessary to change the order of shutting off the power supply in accordance with the replacement or change, which is troublesome. there were.

In addition, depending on the predetermined order of shutting down the power supply, when power is shut down based on that order, such as when the power consumption when the load equipment is shut down is small, it is not necessary to shut off just one load equipment. It is not always possible to obtain the peak cut effect, and it may be necessary to shut off many of the preset load devices, and the peak cut efficiency may not be good, or load devices in a room with people There is also a problem that there is a risk of inconvenience.

Therefore, the present invention has been made in view of such problems and circumstances, and it is not necessary to set the order of the operation control in the load equipment that is the object of operation control. In the case where there is a load, it is possible to control the operation with priority given to load equipment in places where there are no people, and to control the number of load equipment to be as small as possible. Control is performed so that a larger number of load devices can be used, and control is performed with priority given to load devices where there are people. In other words, load devices cannot be used when the operation is stopped. A device system that can efficiently prevent all blackouts caused by excessive use of electricity so that inconvenience can be reduced and as many load devices as possible can be used. It is an object to provide a method.

In order to achieve the above object, according to the first aspect of the present invention, the change amount of the current flowing in the electric circuit when the operation of the predetermined load device is started and the change amount of the current flowing in the electric circuit when the operation is stopped are determined by the predetermined load. When the operation state of the device is controlled, it is measured by the current monitoring means and stored in the storage means as current change amount data, while the storage data in which the control order of the load device is determined and the vicinity of the predetermined load device Is stored in the storage means for each predetermined load device in association with the current change amount data, and is stored and accumulated every time the operation state of the predetermined load device is controlled. the existing current change amount data, the average value of the newly measured and obtained current change amount data is calculated by the current monitoring means, to update the stored accumulated data as a new current change amount data Together, by the control sequence is replaced based on the magnitude of the current change amount data, when controlling the operating state of the predetermined load devices so that the current flowing through the path becomes small, due to the operation stop Data is read from the storage means in order from a predetermined load device having a large amount of change in the current flowing through the electric circuit, and the operation is performed when there is no person in the vicinity of the predetermined load device based on the operation status data of the human sensor. When there is a person, the control of the predetermined load device in that order is skipped, and the operation state of the predetermined load device is controlled so that the current flowing through the electric circuit is increased. the amount of change current flowing in the path with is to start the operation in order from a small predetermined load device, based on the operating status data of the human sensor, a human in the vicinity is That a predetermined operation start of the load device is obtained by providing a device control method is characterized in that the priority process.

As a result, it is not necessary to set the order of operation control in the load equipment that is subject to operation control, and it is highly convenient. The current in the electric circuit increases with the use of various load equipment, and a total power outage may occur. If there is, the operating state is controlled in order from the load equipment that is not close to the person and consumes a large amount of current, considering both the information from the human sensor and the current consumption information. In order to reduce the operating current, the number of load devices to be controlled is reduced until the current becomes large enough to maintain the convenience of the user and eliminate the possibility of a total power failure. When controlling the operating state of a load device so as to increase the operating current, the operating state is controlled in order from the load device with the lowest current consumption. Many negative It is possible to control the equipment to the operating state, and the user can control a smaller number of load equipment while maintaining convenience without being aware of the order of control, and at the same time, there is no risk of total power failure In this range, it is possible to provide a control method for efficiently preventing all blackouts so that more load devices can be used.

In addition , since load devices in the vicinity of a person are prioritized and the operation is started, a control method that can start operation in the vicinity of people as soon as the load device starts operation (returns) and provides more convenience is provided. Is possible.

According to the present invention, priority is given to a load device in a place where there is no person when there is no need to set the order of the operation control in the load device to be subjected to the operation control, which is highly convenient and there is a possibility of a total power failure. It is possible to control the operation so that the number of load devices is reduced as much as possible, and to use a larger number of load devices in the current range where there is no risk of a total power outage. In addition, the load equipment in the place where people are present is given priority, that is, it is possible to reduce the inconvenience that the load equipment cannot be used when the operation is stopped, and use as many load equipment as possible. Therefore, it is possible to provide a device control method that can efficiently prevent all blackouts caused by excessive use of electricity.

Hereinafter, a device control method according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a device control system to which the device control method of the present invention is applied. As shown in FIG. 1, the device control system includes an electric circuit 1, a device control device 2 connected to the electric circuit 1, and a LAN (local area network) 3 which is a communication path for communicating with the device control device. An operation terminal 4 connected to the LAN 3, an Internet connection means 5 for connecting the LAN 3 and the Internet, the Internet 6, an operation terminal 7 connectable to the Internet 6, and a plurality of devices connected to the device control device 2. It comprises load devices A81, B82, C83, D84 and human sensors 811 and 831 arranged in the vicinity of the load device. Although the present embodiment shows a case where there are four load devices, the number may be increased or decreased as necessary.

The device control apparatus 2 includes a current monitoring unit 101 for measuring the magnitude of the current flowing in the electric circuit, a monitoring current setting unit 102 for setting the magnitude of the monitoring current, a consumption current storage unit 103, and various calculations. Computing means 104, equipment control means 105 for controlling the load equipment, storage means 106 for storing various programs, an input / output unit 107 connected to the LAN 3, a signal receiving unit 108 from a human sensor, Have

The monitoring current setting means 102 sets the magnitude of the current to be monitored. Usually, the monitoring current setting means 102 is determined based on the rated current of the main breaker or current limiter (limiter) provided in the distribution board provided in the electric circuit. The determined monitoring current value is input to the calculation means 104.

The calculation means 104 calculates the magnitude of the current flowing in the electric circuit with respect to the value of the monitoring current from the magnitude of the current flowing in the electric circuit detected by the current monitoring means 101 and the value of the monitoring current set by the monitoring current setting means 102. Find the percentage. For example, when the set value of the monitoring current is 60A and the current flowing through the electric circuit is 36A, the ratio of the magnitude of the current flowing through the electric circuit to the value of the monitoring current is 60%. Further, when the current flowing through the electric circuit is 72 A, the ratio of the magnitude of the current flowing through the electric circuit to the value of the monitoring current is 120%.

The device control means 105 is provided so as to be interposed between the electric circuit 1 and the load devices A81 to D84, and the load device is provided so that power is supplied via the device control means 105. Control of power supply is performed using a relay. In addition to using a relay, some load devices can be controlled by HA (home automation), so the power source of the load device is obtained from the electric circuit, and the operation control of the load device is performed using the HA controller. For this purpose, the device controller may be provided with an HA controller.

The consumption current storage means 103 stores the consumption current of each load device. The current consumption of the load device is determined based on the change in the current flowing through the electric circuit when the load device is controlled by the device control means 105. For example, when the ratio of the magnitude of the current flowing through the electric circuit to the value of the monitoring current is 120% (72 A), when the current flowing through the electric circuit becomes 60 A by controlling the load device 81, the calculation unit 104. As a result, the current consumption of the load device 81 is calculated as 72A-60A = 12A and stored in the storage means 103. FIG. 2 shows correspondence data stored in the storage means 103 between the load device, the current consumption, and the order of control.

The storage unit 106 stores various programs, which are read out and calculated by the calculation unit 104. As various programs, a program for calculating the ratio of the magnitude of the current flowing in the electric circuit to the set monitoring current, a program for reading and writing necessary data from the consumption current storage means 103, and an operation for accepting the operation of the device control device A web server program is stored.

The human sensors 811 and 831 are arranged in the vicinity of the load device using a pyroelectric sensor that senses infrared rays emitted by a person. When there is a person in a place (for example, the same room) where the load device is located by placing it near the load device, the human sensor reacts and a signal is received by the sensor signal receiving unit 108, and a person is located near the load device. The calculation means grasps that there is. Various other human sensors may be used as the human sensor. In addition, although wired communication is used between the human sensor and the sensor signal receiving unit 108 of the device control device 2, it may be configured using wireless communication. For example, it may be configured by using a communication method that conforms to a communication standard defined by IEEE 802, in particular, using ZigBee that uses IEEE 802.15.4. Note that correspondence information (described later) between predetermined load device information and human sensors arranged in the vicinity of the load device may be stored in association with the storage unit 103. In addition, since it is only necessary to be able to grasp the presence of a person, instead of a human sensor provided in the vicinity of the device, information on entering / exiting a predetermined room (for example, cooperation with a reader such as an RFID or a security card) The device control device 2 obtains information indicating that a person has entered or left the room), so that the control target equipment in the room where the person is present is not controlled or is given priority. May be.

The operation of the device control device 2 is basically performed via the LAN 3, and the web server of the device control device 2 is accessed from the web browser screen provided in the operation terminal 4 or the operation terminal 7, and provided by the web server. Perform necessary operations from the operation screen.

Next, the flow of the device control method using the present invention will be described. FIG. 3 shows the stage of collecting the current consumption of each load device.

First, the monitoring current is set in the device control device 2 (step S001).
Next, for each load device, a temporary control order is determined by the calculation means (step S002). FIG. 4 shows stored data in which a tentative control order is determined. The load device A81, the load device B82, the load device C83, and the load device D84 are listed in order from the earliest control order.

Next, collect information on the current consumption of the load equipment. Each load device is operated to measure the change in current flowing in the electric circuit and store it in the storage means.

The calculation means 102 first checks whether there is consumption current data in the storage means for the load device A81 (step S003), and if not, performs operation control of the load 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 computing means 102 checks whether or not there is current consumption data in the storage means for the load device B82 (step S004), and if not, performs operation control of the load 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 computing means 102 checks whether or not there is consumption current data in the storage means for the load device C83 (step S005), and if not, performs operation control of the load device C83 (step S0051), and the current flowing through 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 calculation means 102 checks whether or not there is consumption current data in the storage means for the load device D84 (step S006), and if not, performs operation control of the load 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).

Then, when the consumption current data of all the load devices A81 to D84 are collected, the control order is rearranged based on the size of the consumption current data. That is, as shown in FIG. 5, the load device D84 (12A), the load device A81 (10A), the load device C83 (6A), and the load device B82 (3A) are rearranged in the order of control.

This makes it possible to control the load devices with priorities that match the actual usage conditions, compared to the case where the priorities of the load devices to be controlled are fixed, and more efficiently prevent power outages. Will be able to do. In addition, since the user side sets the priority order of the load devices to be controlled so that the device control device conforms to the actual usage state, it is possible to leave the settings without worrying about the control. High operation control is possible.

Further, the current consumption data of the load device may be provided so as to be stored separately for the change amount of the current flowing through the electric circuit when the operation of the load device is started 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 load 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 consideration that the current consumption at the start of operation of the load equipment may differ from the current consumption at the time of shutdown. For example, when floor heating equipment is used as the load equipment, Although it is almost constant at the start and through the steady state, when using an air conditioner as a load device, a large amount of current is consumed at the start of operation to quickly approach the set temperature, and the current consumption at the steady state is greater than at the start of operation. Therefore, when controlling the load equipment so that the current flowing in the circuit is reduced in order to prevent a total power failure, the load equipment that consumes more current when the operation is stopped This is because it is possible to efficiently prevent a total power failure by controlling a smaller number of load devices by giving priority to control.

Also, when controlling the operation of a load device so that the current flowing in the circuit increases, the load device that consumes less current at the start of operation is given priority to control the current so that there is no risk of total power failure. This is because a larger number of load devices can be used in the range, and highly convenient control can be performed.

FIG. 6 shows stored data in which the load device, the amount of change in current in the electric circuit as the operation starts, the amount of change in current as the operation stops, and the control order are stored. When controlling a load device in a direction that reduces the current flowing in the circuit,
Load device D84 (12A)
Load equipment A81 (10A)
Load equipment C83 (6A)
Load equipment B82 (3A)
Therefore, when controlling a load device in the direction that increases the current flowing in the circuit,
Load equipment B82 (5A)
Load equipment A81 (10A)
Load equipment C83 (12A)
Load equipment D84 (15A)
The operation is controlled so that

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

In the examples shown so far, the priority control order of the load devices A81 to D84 is determined by the device control device 2, but in some cases, the user does not want to control as much as possible about a specific load device. Or it may be the case that you want the control to be performed first for a specific load device. For this reason, an item for fixing the order may be provided in the stored data so that the order of control is fixed for a specific load device or a plurality of load devices.

FIG. 7 shows an example of stored data provided with items for fixing the order. The user accesses the web server of the device control apparatus 2 from the operation terminal 4 or the operation terminal 7, receives a predetermined operation screen data, selects a load device for which the control order is to be fixed, and selects the control order. Enter. 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 data is input from the operation terminal and there is data that the order of stopping the operation is to be last for the load device A81 (there is a lock), as shown in FIG. 7, the operation of the load device A81 is performed. The stop order is fourth, the check is made in the fixed column to correct the stored data, and the remaining three load devices that are not fixed in order are sorted again in descending order of the current consumption data at the time of operation stop. In other words, when controlling a load device in a direction that reduces the current flowing through the circuit,
Load device D84 (12A)
Load equipment C83 (6A)
Load equipment B82 (3A)
Load equipment A81 (10A) (fixed order)
Modify to be.

In addition, when there is data indicating that the order of starting operation is to be the first for the load device A81, the operation start order of the load device A81 is the first, and a check (with lock) is made in the fixed column. The stored data is corrected, and the remaining three load 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 the load device in the direction of increasing the current flowing in the circuit,
Load equipment A81 (10A) (fixed order)
Load equipment C83 (3A)
Load equipment B82 (5A)
Load equipment D84 (15A)
Modify to be.

In addition, in order to collect the consumption current data of the load device, the method of operating the load device once in order 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 determined, when there is a possibility of actual power failure, the load equipment is controlled based on the provisional control order, and the current flowing through the electric circuit before and after the controlled load equipment is controlled. You may provide so that it may control using the method of collecting the consumption current data of the load apparatus by measuring. In this case, there is a convenience that it becomes unnecessary to operate the load devices once in order.

Further, these stored data are updated each time the operation control of each load device is performed. For example, when the operation control of the load device A81 is performed, the amount of change in the current flowing in the electric circuit before and after the operation control is performed is measured, and the consumption current data of the load device A81 stored in advance and the newly stored data 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 load device is averaged, thereby reducing the contribution of errors and the like and enabling accurate control.

Next, the flow of the monitoring control state of the device control apparatus 2 will be described with reference to FIG. 6, FIG. 8, FIG. 9, and FIG. FIG. 6 shows stored data in which the load device described above, the amount of change in current in the electric circuit accompanying the start of operation, the amount of change in current accompanying the stop of operation, and the control order are stored. FIG. 8 shows the flow accompanying the stop of operation, FIG. 9 shows the flow accompanying the start of operation, and FIG. 10 shows the current state stored in the storage means 103 and referenced in each flow. A data table is shown. The current status data table stores the current operation status data of the device, control operation data indicating whether control has been performed, and human sensor response data.

When controlling the load equipment in a direction that reduces the current flowing in the circuit,
Load device D84 (12A)
Load equipment A81 (10A)
Load equipment C83 (6A)
Load equipment B82 (3A)
age,
When controlling the load equipment in the direction that increases the current flowing in the circuit,
Load equipment B82 (5A)
Load equipment A81 (10A)
Load equipment C83 (12A)
Load equipment D84 (15A)
The operation is controlled so that the load sensor A81 and the human sensor are provided in the vicinity of the load apparatus C83.

The case where a current limiter is provided on the distribution board will be described. The ratio of the magnitude of the current flowing in the electric circuit to the value of the monitoring current in terms of percentage is hereinafter simply referred to as the ratio. First, the flow for stopping operation will be described.

First, when the device control apparatus 2 starts current monitoring (step S101), the calculation means calculates whether the ratio exceeds 100% for a predetermined time (step S102).

When the ratio exceeds 100%, the control table shown in FIG. 6 and the current data table shown in FIG. 10 are referred to (step S103, step S104), and the control order and current status are determined. To grasp. If the ratio does not exceed 100%, the process returns to step S101 and continues. 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.

In step S103 and step S104, after grasping the control order and the current status, refer to the load equipment corresponding to each control order and the current status information corresponding to the load equipment to check whether the conditions for stopping operation are applicable. Is performed (step S105).

Here, the conditions for stopping the operation are that the current operating state of the load device is ON in the current state data table, and that no human sensor is provided or there is no human sensor response data. Checks are performed in order starting with the load device with the first control order. Control is performed for those that satisfy the conditions for stopping operation. If there is any change in the operation status data or control action data, the current data In addition to storing new data in the table, the change in the current flowing through the electric circuit when the operation of the load device is stopped is measured and stored in the storage means as consumption current data associated with the operation stop. It is measured whether it exceeds% (step S106). If it exceeds 100%, the control of the load device in the next order is attempted, and it is repeated up to the number of load devices provided (fourth).

FIG. 11 shows a current data table storing new data. Here, the load device A81 and the load device C83 with the human sensor response data are skipped while the operation state is ON, and the operation of the load device B without the human sensor is stopped while the operation state is ON. Shows the state.

If the check and control are completed from the 1st to the 4th and the current ratio exceeds 100%, the operation state of the load device is ON as the next step, and the human feeling For the sensors whose response data is ON, the operation is controlled in order from the earliest control order (step S107).

Measure whether the current ratio exceeds 100% for each control order, and if it exceeds 100%, try to control the load equipment in the next control order that meets the condition, Control all the loaded equipment.

Even after this step, if the current ratio exceeds 100%, there is no other load device that can be controlled, so the process returns to step S101 and waits.

In addition, after checking and controlling from the first to the fourth, if the current ratio does not exceed 100%, the process proceeds to the flow of starting operation (step S108).

Next, the flow for starting operation will be described with reference to FIG. If the current ratio does not exceed 100% after a series of controls in the flow of stopping the operation of the load device, it is measured whether the current is equal to or lower than the return current for a predetermined time (step S201). Here, the return current is determined in advance and has a margin with respect to the monitoring set current, and serves as an index when starting the operation again after stopping the operation. is there. 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.
When the current ratio falls below 100%, further falls below a preset return current, and 60 seconds have passed, the operation is started (returned) for the load device whose operation has been stopped.

If the magnitude of the current flowing in the electric circuit for a predetermined time is equal to or less than the return current, the latest status data table and the control order data table described above are referred to (step S202).

In step S202, after referring to the control order and the latest status data table, whether the load equipment corresponding to each control order is compared with the current status information corresponding to the load equipment, and whether the conditions for starting operation are met A check is performed (step S203).

Here, the conditions for starting operation are that the operation state is OFF, that the control operation is performed, and that the sensor reaction data is ON. When there are a plurality of checks whose sensor response data is ON, the check is performed with priority given to the control order that is earlier, and if there is a condition that satisfies the condition, the operation of the load device is started. If there is any change in the operation status data or control operation data, new data is stored in the current data table (step S204), and the change in the current flowing through the electric circuit when the operation of the load device is started is measured. (Step S2051), it is stored in the storage means as consumption current data associated with the stop of operation, and it is measured whether the ratio of current exceeds 100% for each order (Step S206).

If it does not exceed 100%, the process proceeds to S101 of the monitoring step and the process is repeated. If it exceeds 100%, the process proceeds to step S103, and the flow process for stopping the operation of the load device is performed again.

As described above, the amount of change in the current flowing through the electric circuit when the operation of the predetermined load device is started, the amount of change in the current flowing through the electric circuit when the operation is stopped, and the human sensor arranged in the vicinity of the predetermined load device. When the operation status data is stored in the storage means for each predetermined load device in association with the operation status data and the operation state of the predetermined load device is controlled so that the current flowing through the electric circuit becomes small, the current flows through the electric circuit accompanying the operation stop. Data is read from the storage means in order from a predetermined load device having a large amount of current change, and operation is stopped when no person is present in the vicinity of the predetermined load device based on the operation status data of the human sensor. In addition, when there is a person, the control of the predetermined load device in that order is skipped, and when the operation state of the predetermined load device is controlled so that the current flowing in the electric circuit becomes large, the operation start is started. Since the device control method is provided by starting operation in order from a predetermined load device with a small amount of change in the current flowing through the electric circuit, it is not necessary to set the order of the operation control in the load device subject to operation control In the case where there is a risk of a total power outage, it is possible to control the operation with priority given to the load equipment in a place where there are no people and control the number of load equipment to be as small as possible. In addition, control is performed so that a larger number of load devices can be used in the current range where there is no possibility of a total power outage, and control is performed with priority given to load devices in places where people are present. Can reduce the inconvenience of not being able to use the load equipment when the operation is stopped, and by using too much electricity so that as many load equipment as possible can be used. It is possible to provide a device control method which can perform prevention of all power failure occurring efficiently.

Various examples of load devices can be assumed other than those described above, and are not limited to those described above. Further, it is noted that the device control means 105 may be provided so as to perform control using a wireless signal transmission means other than those using the relay and HA described above.

Since the present invention is a method of controlling the operation based on the current consumption of the load equipment that is actually connected, not only in the house as described above, but also the damage of the equipment stop due to the occurrence of a total power failure.

Claims (1)

A method of monitoring the current flowing in an electric circuit and controlling the operating state of a plurality of predetermined load devices based on the magnitude of the current,
The current monitoring means measures the amount of change in the current flowing through the circuit when the operation of the specified load device starts and the amount of change in the current flowing through the circuit when the operation is stopped when the operating state of the specified load device is controlled The current change data is stored and stored in the storage means as current change amount data, while the storage data in which the control order of the load device is determined and the operation status data of the human sensor arranged in the vicinity of the predetermined load device Store in the storage means for each predetermined load device in association with the quantity data,
Each time the operating state of the predetermined load device is controlled,
The average value of the current variation data stored and accumulated and the current variation data newly measured by the current monitoring means is calculated,
Updates the stored accumulated data as a new current change amount data, by the control sequence is replaced based on the magnitude of the current change amount data,
When controlling the operating state of a given load device so that the current flowing in the circuit is reduced,
Data is read from the storage means in order from a predetermined load device having a large amount of change in the current flowing through the electric circuit due to the operation stop, and there is no person in the vicinity of the predetermined load device based on the operation status data of the human sensor. If there is a person, the control of the predetermined load equipment in that order is skipped.
When controlling the operating state of a given load device so that the current flowing through the circuit becomes large,
The operation of a predetermined load device having a person in the vicinity is started based on the operation state data of the human sensor, starting operation in order from a predetermined load device having a small amount of change in the current flowing through the electric circuit at the start of the operation. A device control method characterized in that start is prioritized.
