The above-described HEMS is a means for monitoring equipment in the home that uses electricity, gas, water, etc., and controlling them according to the purpose. In addition, an operation plan that takes into account weather conditions that change daily and revised electricity rates is generated, and household equipment is controlled based on such an operation plan.
Price plans for electricity provided by electric power companies, pricing for selling electricity generated by installed solar panels, and other various conditions are not uniform for each household. In addition, it is practically difficult for each household to formulate and execute an energy use plan independently from the viewpoints of energy saving and energy saving.
Under such circumstances, an optimum operation plan is formulated by a server provided separately, and the operation plan is transmitted from the server to the equipment in the residence constituting the HEMS via the Internet. Controlling the equipment is done. Since such an operation plan differs every day, it is ideal that it is basically updated every day or every predetermined time.

As described above, it is ideal that the operation plan formulated for each household is updated every day or every fixed time, but the operation plan is not updated because the server and the devices constituting the HEMS cannot communicate with each other. There is a case.
In this case, if the equipment that constitutes the HEMS continues to operate according to the operation plan that has not been updated, there is a possibility that the operation will deviate greatly from the predicted weather conditions, etc. Will not be able to meet the demands of those who are. The present invention has been invented in view of the above problem, and when the server and the devices constituting the HEMS cannot communicate with each other and the operation plan is not updated, etc., energy saving, saving of utility costs, efficient It is an object of the present invention to provide a home appliance control system that can perform an appropriate operation from the viewpoint of the use of various energy.

The server periodically transmits the operation plan to the control device, and the controlled device is operated according to the operation plan transmitted from the control device and stored in the storage means. The storage means can store the device operation setting determined by the user as a default operation plan, and the server predicts power consumption and stores the default stored in the storage means. Compared with the operation plan, a high-value operation plan for the user is created with a predetermined time width, and the controlled device is operated with the predetermined time width based on the operation plan. When the controlled device fails to receive the operation plan, the controlled device operates the controlled device based on the operation plan stored in the storage means as the default. Features.

  The present invention is a residential equipment control system for operating controlled equipment installed in a residence based on an operation plan formulated by a server, and is based on default settings when the operation plan established by the server cannot be obtained. Then, the controlled device is operated. The operation plan is formulated from the viewpoint of energy saving, reduction of utility costs, etc., including factors such as temperature changes on the operating day and weather conditions such as weather, so it cannot be applied on other days. For this reason, when the operation plan formulated by the controlled device cannot be obtained or executed, the controlled device is operated based on the default control information stored in the storage unit of the controlled device in advance. Yes.

The default control information is different for each controlled device. For example, in the case of storage batteries and hot water supply devices, a certain amount of power storage or hot water can be used by using power at low prices depending on the contract with the power company. Boil up. As described above, when a detailed operation plan cannot be obtained, operation is performed from the viewpoints of energy saving and reduction of utility costs as much as possible.

  Hereinafter, modes for carrying out the present invention will be described. FIG. 1 is an explanatory diagram showing an outline of a home appliance control system 1 according to the present invention. The residential equipment control system 1 is a system for controlling various equipment installed in each house shown as the residence H1, the residence H2, the residence H3. The various devices installed in each residence are connected to one or a plurality of servers Sv (Sv1, Sv2) directly or indirectly via the Internet I, and the operation plans received from the server Sv or programs provided in the various devices. Driving is performed based on this.

In the house H1, as an example, a storage battery 2 that stores electric power generated by energy generation means such as solar power generation or electric power acquired in an inexpensive time zone is installed. Further, similarly to the storage battery 2, hot water for hot water supply is generated using solar power generation or inexpensive nighttime power, and a hot water supply device 3 is mainly stored for use during the daytime. Furthermore, a heating device 4 and an air conditioning device 5 that use the accumulated electric power and hot water supply are installed.
In addition, when equipped with a facility for performing solar power generation, a smart meter Sm and an information distribution board B are installed, and control such as selling power generated by solar power generation, purchasing commercial power, etc. Management is performed.
The various devices described above are communicably connected to the control device HGW, and the control device HGW is communicably connected to a server Sv connected to the Internet via the router R. The control device HGW has a function of controlling or monitoring the above-described various devices installed in the residence H as controlled devices.

The storage battery 2, the hot water supply device 3, the heating device 4, and the air conditioning device 5 will be described as examples of controlled devices controlled or monitored by the control device HGW. The residential device control system 1 does not have to include all of these controlled devices, and other alternative facilities or other facilities may be added.
The storage battery 2 is a facility configured to store electric power generated by solar power generation or commercial power so that the stored electric power can be used as appropriate. Specifically, a simple operation (operation described in the column of “No automatic control” in FIG. 2) that performs charging or discharging in a time zone set by a timer, or an operation plan obtained via the control device HGW This is a device that can be charged, discharged, etc. (operation described in the column “with automatic control” in FIG. 2). As an example, the storage battery 2 has a mode currently provided such as an independence rate priority mode, an economic priority mode, an output suppression function, and power failure information support, and a function scheduled to be added in the future.

The operation described in the column of “No automatic control” shown in FIG. 2 is the control content when there is no operation plan acquired from the server Sv or the operation plan is not executed, such as the initial setting at the time of factory shipment.
The operation described in the column “with automatic control” shown in FIG. 2 is control when the operation plan acquired from the server Sv is executed. From the viewpoint of energy saving and saving of utility costs, an optimal operation plan for operating the storage battery 2 is provided.

For example, in the operation plan after the end of FIT, as an independence rate priority mode, if surplus power is utilized as much as possible, but surplus power is not enough, driving that emphasizes the economy of charging with power in the time zone where the unit price of electricity is low Run the mode.
In addition, in the operation plan during the FIT period, as an economic priority mode, surplus power is sold and charged with power in the midnight hours when the unit price of electricity is low, and according to the power consumption of the user Discharge that is economically advantageous.

  The storage battery 2 includes various devices for performing operations such as charging and discharging, and a storage unit 21 as a storage unit that stores various information including a calculation unit such as a CPU that controls them, a control program, and default settings. Have. The storage battery 2 executes the operation plan set for the storage battery 2 by communication (command or the like) with the control device HGW. The default stored in the storage unit 21 is, for example, the setting of the start time and end time of the charging time zone and the discharging time zone that are set in accordance with the economic priority mode when the user selects the economic priority mode. is there. Further, the operation status is output to the control device HGW, and a new operation plan is acquired periodically or each time.

  The hot water supply device 3 is a hot water supply facility having a high energy saving effect using a heat pump, and performs boiling of hot water and hot water storage. For example, the hot water supply device 3 performs control to boil hot water during the day by using as much as possible the surplus power of solar power generation or the storage battery 2 and boil the amount that is not sufficient with surplus power at midnight. In this operation mode, the operation efficiency is high by boiling during the day when the temperature is higher than midnight, and energy saving can be achieved by shortening the heat retention time. In addition, on days when there is little surplus power such as rain, control is performed according to an operation plan based on weather conditions such as boiling water as much as possible at midnight.

The hot water supply device 3 stores various means used for boiling water and hot water, and a storage means for storing various information including a calculation means such as a CPU for controlling them, a control program, and a default operation mode. Control means having a part 31 is provided.
The control means executes the operation plan set for the hot water supply device 3 by communication (command or the like) with the control device HGW. Further, the default stored in the storage unit 31 is, for example, a setting such as a start time at which the user starts boiling water. Further, the operation status is output to the control device HGW, and a new operation plan is acquired periodically or each time.

In this embodiment, the heating device 4 that is one of the air conditioning devices is formed as a device that heats the room by a radiator disposed under the floor or indoors. For example, there is one that functions as underfloor heating by installing a radiator connected to an outdoor unit under the floor of the first floor. In addition, there are some which heat the inside of a residence by a radiator disposed under the floor of the first floor and a radiator disposed in each room of the second floor.
The operation described in the column of “No automatic control” shown in FIG. 3 is the control content when there is no operation plan acquired from the server Sv or the operation plan is not executed, such as the initial setting at the time of factory shipment. For example, in “without automatic control”, the heating device 4 uses the midnight power according to the operation mode set at the time of factory shipment, and performs an operation of heating the floor under the building or the frame.

The operation described in the column “with automatic control” shown in FIG. 3 is a control content in the case of performing an efficient heating operation based on the operation plan acquired via the control device HGW.
In automatic control based on the operation plan, for example, based on the predicted outside air temperature of the next day's weather forecast information and the input schedule by the user, stop the midnight keep operation to reach the set temperature environment at the user's wake-up time Control is performed to determine the possible time. The purpose of this is to save energy in accordance with daily life, and control is performed such that the stop time is longer on days when the outside air temperature is higher and the stop time is shorter on days when the outside temperature is low. Further, it is possible to clarify the difference in the entry time depending on the day from the power consumption information, etc., and to perform control or the like that can ensure the comfort of the user even when the entry time is early. In addition, the operation considering the unit price of electric power is also possible.

The default stored in the storage unit 41 is, for example, timer settings such as an operation start time and an operation end time that are set according to a lifestyle (wake-up time, absence time) and a desired power charge by the user. . Further, the operation status is output to the control device HGW, and a new operation plan is acquired periodically or each time.

The air conditioner 5 is an air conditioner that functions as a so-called air conditioner that heats or cools the room, and is an apparatus that exhibits an energy saving effect by optimizing operation at midnight while maintaining comfort. For example, the operation without “automatic control” is control when there is no operation plan acquired from the server Sv or the operation plan is not executed, such as with the factory default settings. For example, in “without automatic control”, the air conditioner 5 uses the midnight power according to the operation mode set at the time of shipment from the factory, and performs an operation of cooling and heating the floor, the frame, and the room of the building.
The operation described in the column “with automatic control” represents a case where an efficient air-conditioning operation is performed based on an operation plan acquired via the control device HGW.

When heating the air conditioner 5 by automatic control, an operation plan is formulated based on the predicted outside temperature of the next day's weather forecast information and the customer's input schedule.
In this operation plan, during the midnight keep operation time, the time when the user can wake up at the set temperature environment at the time of wake-up and determine the time that can be used for the weak operation (energy saving keep) with less power consumption than the midnight keep operation is determined. By setting a specific weak driving time, it is possible to perform energy-saving driving according to daily life. Further, as an example of the operation plan, an energy saving keep time is lengthened on a day when the outside air temperature is high, and an energy saving keep time is shortened on a low day.

When the air conditioner 5 is to be cooled by automatic control, an operation plan is formulated based on the user's input schedule.
In this operation plan, of the midnight dehumidification operation time, it is determined the time that can be operated weaker (energy saving keep) than midnight dehumidification operation under the condition of reaching the set humidity environment at the wake-up time, and efficient weak operation By setting the time of the energy saving operation to fit the daily life.
In addition, it is possible to make a control aiming at improvement of comfort, such as clarifying the difference in entrance time depending on the day from human sensor and power consumption information, and ensuring comfort even when the entrance time is early. It is also possible to formulate and implement an operation plan that takes into account the unit price of electricity.

The air conditioner 5 serves as a storage means for storing various means for driving the outdoor unit, setting the temperature, selecting a radiator to be used, a calculation means such as a CPU for controlling them, a control program, and other various information. Control means having a storage unit 51 is provided.
The control means executes the operation plan set for the air conditioner 5 by communication (command or the like) with the control apparatus HGW. The default stored in the storage unit 51 is, for example, a timer setting such as an operation start time and an operation end time set according to a lifestyle (wake-up time, absence time) and a desired power charge by the user. . Further, the operation status is output to the control device HGW, and a new operation plan is acquired periodically or each time.

  The storage battery 2, the hot water supply device 3, the heating device 4, the air conditioning device 5, etc. described above function as controlled devices controlled by the control device HGW. Various types of information are received or transmitted. The control device HGW is also referred to as a HEMS terminal, and is configured to communicate with the server Sv via the router R connected to the Internet I. The control device HGW has calculation means such as a CPU, a control program for the control device HGW itself, and storage means for storing various information. Input means such as a remote control device (the wall-mounted remote control 6, the Web remote control 7) are provided. Various settings and controls are used.

The main functions of the control device HGW are listed as follows.
The server Sv1 (control server) is requested for an operation plan, and the operation plan for one day sent is held in the storage unit HG1 as storage means.
-The operation plan is disassembled as an operation plan for the controlled device and transmitted to each controlled device shortly before the designated time.
-When an operation plan is requested from the server Sv1 and cannot be received, it is requested again after a certain time, and acquisition is attempted as much as possible.
If the operation plan cannot be distributed from the control device HGW to each controlled device, it is retransmitted until the designated time is reached, and distribution is attempted as much as possible.

・ If the operation plan cannot be distributed, acquire the cause and record the information to identify the controlled device that could not be distributed.
When there is the wall remote controller 6 and the Web remote controller 7, when one of the operations for turning off (or turning on) the automatic control is performed, the information is transmitted to the other remote controller.
If the operation plan cannot be received from the server Sv1, it is transmitted to each controlled device.
The actual setting state of each setting item is acquired for the controlled device specified in the operation plan, and is transmitted to the server Sv1 every day as data at the same time interval as the operation plan.
The controlled device for which the operation plan has not been distributed acquires the cause and transmits it to the server Sv1 via the control device HGW. When the cause cannot be transmitted, the data is retained at least for the same period as other server transmission data (power data or the like).
As described above, the control device HGW has a function of relaying various information such as control information based on the operation plan, setting information of the controlled device, and actual operation status between the server Sv1 and each controlled device. doing.

The present invention actually uses a plurality of servers, but in the present embodiment, these servers are alternatively described as two servers Sv1 and Sv2.
The function of the server Sv1 is as follows.
-A function for classifying operation plans sent from the server Sv2 for formulating operation plans into residences, and requesting operation plans from the control equipment HGW (HEMS terminal) of each residence (H1, H2, H3...) If there is, an individual operation plan is transmitted for each house (H1, H2, H3...). In addition, information such as from which house the request is made and the operation plan can be transmitted is recorded.
・ If the requested residence does not obtain an operation plan, record the residence code and the target device.
The actual device setting state data for the operation plan of each residence (H1, H2, H3...) Transmitted from the control device HGW is received.
Pass the recorded data and received data to the server Sv2.

The function of the server Sv2 is as follows.
・ Predict electricity consumption and create an operation plan. Prediction of power consumption is performed based on weather forecast data such as solar radiation forecast and outside air temperature forecast, a power rate plan selected by the user, and past user history data stored in the server Sv2.
The user's past history data includes the history of the user's past power consumption, the history of the operation status of the controlled device installed in the user's home, and the like. These pieces of information are input to a prediction model, a predicted value of power consumption is calculated, a device-specific control process is performed, and an operation plan is created.
The operation plan is created with a predetermined time width so that the operation plan is more valuable to the user than the default operation plan stored in the storage unit 21, 31, 41, 51 of the controlled device. . The operation plan with high value for the user is determined by criteria such as comfort, economy, power saving, or convenience of power supply at the time of power failure.
The operation plan is created with a predetermined time width set every 30 minutes, every hour, every 24 hours, etc. For example, when an operation plan for a control cycle of 24 hours is created with a predetermined time width of 1 hour, a set of 24 instruction data is obtained.
-Pass the created operation plan to the server Sv1.
・ If there is a residence where an operation plan could not be created, record the date, residence code, and cause.
Receive and record actual device setting status data from each residence via the server Sv1.

In FIG. 4, the explanatory view expressed in time series about preparation of an operation plan and transmission / reception of the operation plan in the household equipment control system 1 was shown. The operation plan created by the server Sv2 based on the accumulated history information (history data) and setting information is determined by the control device HGW (HEMS terminal) of each residence (H1, H2, H3...). Delivered on time.
Then, in each residence (H1, H2, H3...), The operation plan is transmitted from the control device HGW to the controlled devices (2, 3, 4, 5) serving as home devices, and the storage units 21, 31 , 41, 51.
The operation plans stored in the storage units 21, 31, 41, 51 are used for operation control of actual controlled devices (2, 3, 4, 5), and history information and settings newly generated by the operation are stored. Information is transmitted to the server Sv1 via the control device HGW and accumulated as history data.

Each controlled device connected to the control device HGW has the following common functions, except for restrictions based on device-specific functions.
Automatic control can be switched on / off, and is switched by designation of the Web remote controller 7.
When the automatic control is on, the operation plan distributed from the control device HGW is received.
-When automatic control is on, the device status is set according to the received operation plan from the start time of the next control cycle (every 30 minutes, every hour, etc.).
-When automatic control is on, if the operation plan is not received by the control cycle start time, it operates in the next control cycle based on the default setting of each device.
-When automatic control is on, display on the wall remote control so that it can be distinguished whether or not it is operating according to the operation plan.
When the automatic control is turned off, the operation plan is cleared, and the operation is performed based on the initial settings or the default settings stored in the storage units 21, 31, 41, 51, respectively.
When the device is operated with the Web remote controller 7, the wall remote controller displays that the operation has been accepted.

  The flow of various information including the operation, control, and operation plan of the wall-mounted remote control 6, the web remote control 7, the control device HGW, the server (communication server, control server) Sv1, and the server Sv2 constituting the residential device control system 1 As shown in FIG.

  The operation plan formulated by the server Sv2 includes a mode such as strength and weakness, an operation designation parameter for each time zone, a parameter referred to in the entire operation plan, a time at which an operation is started by the operation plan, and a device operated by the operation plan. The specified information etc. are included.

As described above, each controlled device installed in the residence (H1, H2, H3...) Is controlled based on the operation plan received from the server Sv1.
However, the occurrence of an abnormal situation in which the control device HGW or each controlled device does not operate based on the operation plan due to communication interruption or other reasons is also assumed. In the present embodiment, the following control is performed according to an assumed abnormal situation.
As an assumed abnormal situation, when the operation plan cannot be created by the server Sv2, the operation plan cannot be transmitted from the server Sv1 to the control device HGW of the residence (H1, H2, H3...) Or the control device HGW is operated. When the plan cannot be received, the operation plan cannot be transmitted from the control device HGW to the controlled device (2, 3, 4, 5) or the controlled device (2, 3, 4, 5) cannot receive the operation plan. Can be assumed. For example, when the control device HGW and the controlled device (2, 3, 4, 5) are connected via a wireless LAN (Wi-Fi), an unstable connection state such as communication being interrupted may occur.
In this case, the controlled devices (2, 3, 4, 5) operate based on the default settings stored in the storage units 21, 31, 41, 51.

  As described above, when the operation plan is not distributed to the control device HGW or each controlled device (2, 3, 4, 5), each controlled device (2, 3, 4, 5) is based on the operation plan. It cannot be operated. In other words, from the viewpoint of energy saving and reduction of utility costs, the operation plan is formulated including elements such as temperature changes on the operation day and weather conditions such as weather, and therefore cannot be applied on days other than the scheduled date. For this reason, when the controlled device (2, 3, 4, 5) cannot acquire the operation plan formulated by the server Sv2, the storage unit 21, 2 of the controlled device (2, 3, 4, 5) is previously stored. The controlled device (2, 3, 4, 5) is operated based on the default control information (default setting) stored in 31, 41, 51.

In FIG. 5 and FIG. 6, there is an operation plan storage means only for the control device HGW for comparison with the control of the home device control system 1 of the present embodiment when a communication failure such as communication interruption occurs. The control when there is no storage means on the controlled device side is shown.
FIG. 5 shows an example of control of the air conditioner 5. In the default setting of the top stage, the air conditioner 5 is operated with “medium” strength at midnight, “strong” from early morning to noon, “weak” during the day, and “strong” strength at night. Driving is performed at.
Then, it is assumed that the second-stage operation plan is created and transmitted by the server Sv2. This operation plan has 24 instruction data with a time width of 1 hour, with distribution from the server Sv1 to the control device HGW every day at 22:00, 24 hours as one control cycle.
For example, when the control device HGW cannot receive the operation plan from the server Sv1 at T1 when the operation plan is distributed, the home device control system of the present embodiment in which the default setting is stored in the storage unit 51 of the air conditioner 5 If it is 1, the control cycle of the next 24 hours will operate the air conditioner 5 by default setting. On the other hand, even if the communication between the control device HGW and the air conditioner 5 is interrupted at T2 after the operation plan is distributed, the operation plan is stored in the storage unit 51. The device 5 can be operated.
On the other hand, when the operation plan and default setting are stored in the storage unit HG1 of the control device HGW and the control instruction is given to the air conditioning device every time width of 1 hour, the server Sv1 is connected to the server Sv1 at T1 when the operation plan is distributed. When the communication is interrupted, the air conditioner 5 can be operated with the default setting for the next 24-hour control cycle according to the default setting stored in the control device HGW. However, if communication interruption occurs at T2 between the control device HGW and the air conditioning device, the operation of the air conditioning device after 3 o'clock is the operation with the “weak” strength last transmitted from the control device HGW. It will be fixed and will continue to operate away from the default settings that are of great value to the user.

FIG. 6 shows an example of the control of the storage battery 2. In the default setting of the uppermost stage, the storage battery 2 is “charged (charged)” from midnight to early morning, “standby” from early morning to morning, and “discharged” from morning to night. Is done.
Then, it is assumed that the second-stage operation plan is created and transmitted by the server Sv2. This operation plan has 24 instruction data with a time width of 1 hour, with distribution from the server Sv1 to the control device HGW every day at 22:00, 24 hours as one control cycle.
For example, when the control device HGW cannot receive the operation plan from the server Sv1 at T1 when the operation plan is distributed, the home device control system 1 of the present embodiment in which the default setting is stored in the storage unit 21 of the storage battery 2 is used. If so, the storage cycle 2 is operated at the default setting for the next 24-hour control cycle. On the other hand, even if communication between the control device HGW and the storage battery 2 is interrupted at T3 after the operation plan is distributed, the operation plan is stored in the storage unit 21, so that the storage battery 2 can be stored by the operation plan already distributed after 3 o'clock. Can be operated.
On the other hand, when the operation plan and the default setting are stored in the storage unit HG1 of the control device HGW and the storage battery is instructed to control every hour width, the communication with the server Sv1 is performed at T1 when the operation plan is distributed. When the interruption occurs, the storage battery can be operated with the default setting for the next 24-hour control cycle according to the default setting stored in the control device HGW. However, if a communication interruption occurs at T3 between the control device HGW and the storage battery, the operation of the storage battery after 6 o'clock is fixed in the “standby” state transmitted from the control device HGW at the end. The operation situation will be separated from the default setting which is valuable to the user.

When the controlled device (2, 3, 4, 5) cannot acquire the operation plan created by the server Sv2 in this way, the residential device control system 1 of the present embodiment is optimal in such a state. The controlled devices (2, 3, 4, 5) are operated under various conditions. This optimum condition is stored as a default setting in the storage units 21, 31, 41, 51 of each controlled device (2, 3, 4, 5), and when the operation plan created by the server Sv2 cannot be obtained. The default settings are read from the storage units 21, 31, 41, 51 and executed.
Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention are included in the present invention. is there.
For example, in the above-described embodiment, the case where the device operation setting determined by the user is set as the default setting has been described. You may memorize | store in the memory | storage part 21, 31, 41, 51 as a setting.
