Description

  The present invention relates to a device control system that operates a plurality of devices according to environmental conditions.

  In recent years, energy saving measures have been studied in factories and stores from the viewpoint of tackling environmental problems and reducing energy costs. As an example, it has been considered that a large number of devices installed in a factory or store are monitored by a network, the operation state of each device is grasped, and the device is controlled efficiently by linking each device. Yes.

  For example, in a grocery store or sales floor where many refrigeration equipment such as air conditioners, refrigerators, and showcases are installed, the refrigeration compressor start-up timing depends on the cooling status of the showcase by monitoring each refrigeration equipment. For example, control for optimizing the operation state of each refrigeration equipment is performed.

  The operating state of each refrigeration equipment varies depending on conditions including temperature, time zone, and the like (hereinafter referred to as environmental conditions). For example, when the outside air temperature is high, the load on the compressor increases, so the operation frequency increases. In addition, the internal temperature of the showcase rises during the defrosting operation to periodically remove the frost that has adhered to the inside of the showcase or to prevent frost adhesion, so it is necessary to cool it immediately after the defrosting operation. is there. The environmental conditions include store temperature, store outside temperature (outside temperature), humidity, store enthalpy, time zone, weather, and the like.

  Therefore, the applicant of the present application uses a database that stores the low pressure side pressure setting value of the refrigerator for each operating environment condition, and appropriately refers to the past low pressure side pressure setting value that matches the current operating environment condition. Have proposed a system that realizes a safe operation (see Patent Document 1, FIG. 4 and the like). In the technique of Patent Document 1, the controller 10 has a role of an integrated controller that controls the devices such as the showcases 1a, 1b,.

In addition, a management server (corresponding to a management controller) that manages the operation of the device provided in the store predicts environment information at a predetermined time after the current time, and controls the device based on the prediction result. A technique of generating device control information and controlling a device installed in a store based on the device control information is disclosed (see Patent Document 2).

  In order to perform control for efficiently operating the devices installed in the store in cooperation with each other, it is advantageous to have more control data according to the environmental information. Therefore, it is conceivable to use the same data in other stores when efficiently operating a device installed in one store. For example, when opening a new store, if control data learned in an existing store can be used, it is possible to operate with energy saving from the beginning.

  Patent Document 1 is based on the premise that the device is controlled in a closed system, and the case where the control data such as the low pressure side pressure set value corresponding to the environmental condition of the control data is utilized between different stores. Not listed. If control data according to driving environment conditions is transmitted and received between stores, a device that does not cause adverse effects on the communication path when considering the amount of control data to be transmitted and received, the frequency of communication between the control device and the device, etc. Necessary.

  On the other hand, the technique described in Patent Document 2 includes a management server that manages the operation of the equipment provided in the store, and environmental information such as temperature is accumulated in the management server one by one. It is disclosed that device control information is generated by predicting environmental information in each store and transmitted to each store. However, since the communication load between the store and the management server is not taken into consideration, if the number of connected stores increases, transmission / reception of control data or environmental information is adversely affected due to an increase in communication capacity between the store and the management server. There is a fear.

  Therefore, the present invention has been proposed in view of the above-described conventional situation, and control data used for performing efficient operation in cooperation with a large number of devices installed in a factory or store is provided. An object of the present invention is to provide a device control system capable of reducing a communication load when data is transmitted and received between a management controller and an integrated controller.

The one integrated controller receives the control data group and transmits a part of the received control data group to the device controller. A device controller connected to one integrated controller receives a part of the control data and controls the device using the received control data.

  Therefore, according to such a feature, when there is initial value data in the environmental condition database, another storage area of the environmental condition database including the initial value data is changed to a storage area corresponding to the same environmental condition of another environmental condition database. And the control data is updated according to the comparison result. Therefore, even if there is initial value data in the environmental condition database corresponding to a certain integrated controller, the initial value data can be updated with other control data under the same environmental condition and transmitted to the device controller. In addition, when the control data is transmitted, the control data received from the management controller by the device controller via the integrated controller is the control data used in each of a plurality of environmental conditions from the current environmental condition to the next environmental condition.

The device controller connected to the integrated controller controls the device controller that receives the part of the control data. The gist of the present invention is a device control system having a data receiving unit and a device control unit that controls the device using the received control data.

  According to this feature, the management controller searches an initial value data storage area in which initial value data prepared in advance is stored from one environmental condition database corresponding to one integrated controller among the plurality of integrated controllers, Referring to the device number database, extract and extract the integrated controller that operates the number of devices corresponding to the number of devices connected to the device controller whose cooperative operation is controlled by one integrated controller. The environmental condition database including the initial value data storage area is updated using the environmental condition database corresponding to the integrated controller. In addition, the device controller connected to one integrated controller extracts a control data group to be used in each of a plurality of environmental conditions from the current environmental condition to the next environmental condition, and extracts it from the updated environmental condition database. The obtained control data group is transmitted to the integrated controller. The one integrated controller receives the control data group and transmits a part of the received control data group to the device controller. A device controller connected to one integrated controller receives a part of the control data and controls the device using the received control data.

  Therefore, according to this feature, when there is initial value data in the environmental condition database, the same number of integrated controllers as the number of devices integrated by the integrated controller corresponding to the environmental condition database including the initial value data are searched. By replacing with the environmental condition database of the integrated controller, the device controller can control the device based on the control data that is not the initial value data. In addition, when the control data is transmitted, the control data received from the management controller by the device controller via the integrated controller is the control data used in each of a plurality of environmental conditions from the current environmental condition to the next environmental condition. Since it is a part, the communication load between the management controller and the integrated controller connected via the network and the communication load between the integrated controller and the device controller can be reduced.

  In the above-described feature, the environmental condition associates at least the time zone with the temperature at the time zone, and the control data group extraction unit is a predetermined time ahead from the time zone including the current time. Used by the equipment controller in environmental conditions that include a plurality of time zones up to the time zone, and that include a temperature zone that includes the current temperature, and a temperature zone that is adjacent to the temperature zone. Based on the comparison result of the extracted data comparing unit and the extracted data comparing unit that compares the control data group with the previously extracted control data group, control data that does not overlap with the previously extracted control data is calculated from the control data group And the integrated controller side control data transmission unit preferably transmits the control data calculated by the data calculation unit to the device controller. Arbitrariness.

  As a result, the control data group used in environmental conditions including a plurality of time zones from the time zone including the current time to the time zone ahead of the predetermined time is compared with the extracted control data group, and duplication is performed. By not transmitting the control data to be transmitted, it is possible to reduce the communication load between the management controller and the integrated controller connected via the network, and the communication load between the integrated controller and the device controller.

  According to the present invention, the communication load when transmitting and receiving control data used for efficient operation in cooperation with a large number of devices installed in a factory or store between the management controller and the integrated controller Can be reduced.

The integrated controller 11 and the management controller 3 are connected via a network 5 so that they can communicate with each other. Other stores 2a and 2b are connected to the network 5, and the stores 2a and 2b have an integrated controller that controls the devices installed in the stores to operate in cooperation with each other.

  An example of the network 5 is the so-called Internet constructed by further interconnecting computer networks in which computers are connected to each other. In addition, a network constructed by connecting the management controller 3 and stores using a dedicated line may be used.

The integrated controller 11 is connected to a device controller to which devices constituting the refrigeration facility 12 or the air conditioning facility 13 installed in the store 2 are connected.

  The refrigeration facility 12 mainly includes a showcase 20, a compressor (compressor) 21, and a condenser (condenser) 22. The showcase 20 is connected to the device controller 14. The compressor 21 is connected to the device controller 15. The condenser 22 is connected to the equipment controller 16.

In addition to this, lighting equipment and the like are provided, and are managed by the integrated controller 11 together. Although not shown in FIG. 1, the showcase 20, the compressor 21, and the condenser 22 are connected by a refrigerant pipe. Similarly, in the air conditioner 13, the air conditioner outdoor unit 23 and the air conditioner indoor unit (compressor 24, condenser 25) are connected by refrigerant piping.

(Central database)
The central database (hereinafter referred to as the central DB) 4 includes a variety of general-purpose storage media including a hard disk, a recordable CD, a DVD, and the like, and a reading and writing device for the storage media. Each of the controllers has an environmental condition database in which control data used for operating the device is stored. The environmental condition database is set for each integrated controller that integrates the device controllers (that is, for each store). The environmental condition database may be a logically separated storage area of the storage medium, or may be prepared as a storage medium that is physically divided into individual storage areas.

  FIG. 2 is a diagram schematically showing the structure of the central DB. In the environmental condition database 41a, the equipment controllers 14, 15, 16, 17, 18, 19 integrated by the integrated controller 11 of the store 2 are the showcase 20, the compressor 21, the condenser 22, the air conditioning indoor unit 23, and the compressor. 24, control data for operating each device such as the condenser 25 in cooperation with each other is stored. The environmental condition database 41b stores control data used by a device controller integrated by an integrated controller installed in a store 2a (not shown). In addition, the environmental condition database 41c stores control data used by a device controller integrated by an integrated controller installed in a store 2b (not shown).

  FIG. 3 shows an example of the environmental condition database in the present embodiment. In the present embodiment, three parameters of store temperature, outside air temperature, and time zone are used as environmental conditions. In the environmental condition database, control data used by each device controller to operate the device is stored in a separate storage area (hereinafter referred to as a cell) for the environmental conditions obtained by a combination of these parameters. .

  Next, the environmental condition database will be described. In the environmental condition database, based on the three parameters of the store temperature, the outside temperature, and the time zone, which serve as an index for determining the operating environment condition of the device installed in the store 2, the environmental condition of the device controller Control data used for operating each device is classified into a plurality of stages and stored in a predetermined cell.

  For example, in the case of the refrigeration facility 12, the control data used by each of the device controllers to operate the device under a certain environmental condition is a low-pressure side pressure setting value. The low pressure side pressure set value indicates the refrigerant pressure that serves as a trigger for starting the compressor (compressor) 21. When the refrigerant temperature rises, the refrigerant pressure also rises. Therefore, when the refrigerant pressure rises to a predetermined value, the compressor 21 is driven to lower the refrigerant temperature. Further, since the refrigerant pressure decreases as the temperature decreases, the compressor 21 stops when the temperature decreases to a predetermined value. Generally, when the temperature is high (the load is high), the low pressure side pressure set value is set low. If the low-pressure side pressure set value is set low, the compressor 21 is immediately driven when the refrigerant temperature rises. On the contrary, when the temperature is low (load is low), the frequency at which the compressor 21 is driven can be reduced by increasing the low-pressure side pressure set value, leading to energy saving operation.

  In this embodiment, as an example, the in-store temperature Ti (° C.) is classified in the range of 0 ° C. to + 40 ° C. in increments of 5 ° C. (eight steps). Further, the outside air temperature To (° C.) is classified in steps of 5 ° C. in the range of −10 ° C. to + 40 ° C. (10 steps). Also, the time zone is classified into 12 levels every 24 hours for 24 hours a day. Therefore, the environmental condition database for one integrated controller has a storage area of 960 cells. The range of the store temperature, the outside temperature, and the time zone are the number of cells in the device control system 1 that can secure the minimum amount of control data necessary for safe and energy-saving operation, the store scale, the management controller, or the central DB. It can be set according to the storage capacity.

  For example, if it is a refrigerator (compressor 21, condenser 22), the low pressure side pressure setting value which is control data is stored in each cell of the environmental condition database 41a. First, the initial value (default value) of the low pressure side pressure set value is registered in the cell. Therefore, when the showcase 20 and the refrigerator (the compressor 21 and the condenser 22) are initially installed in the supermarket, the low pressure side pressure set value is set to the default value. Note that this default value is set to a value that is effective in an environmental condition that requires the most cooling capacity, for example. This default value is appropriately updated by the management controller 3 to a value that realizes optimum operation performed for the purpose of reducing power consumption under environmental conditions.

(Configuration of device controller)

Among them, it is a minimum part of the control data that can realize the energy saving operation. The device controller 14 controls the operation of each connected device based on the acquired control data. Therefore, the CPU 52 of the device controller 14 has a function as a device control unit.

The management controller 3 is communicably connected to the central DB 4 via the communication I / F 74. As the communication I / F 74, serial, TCP / IP, and other general-purpose communication interfaces can be applied. The central DB 4 may be incorporated as an external storage device of the management controller 3.

  In addition, the management controller 3 includes a network interface (hereinafter referred to as a network I / F) 75 for connecting to the network 5 (the Internet in the present embodiment), and the integrated controller 11 or other not shown via the network 5. Are mutually communicable with integrated controllers such as the stores 2a, 2b,.

  The CPU 71 of the management controller 3 manages the integrated controller 11 or an integrated controller such as another store 2a, 2b,... (Not shown) based on a program stored in the ROM 72 or the like. The management controller 3 receives control data generated by each device controller at a predetermined timing via the integrated controller, and updates the cell of the corresponding environmental condition in the central DB 4. In addition, the management controller 3 extracts a control data group used by the device controller under each of a plurality of environmental conditions from the current environmental condition to the next environmental condition, and transmits the control data group to the integrated controller 11.

  An example of the functional configuration of the management controller 3 will be described with reference to FIG.

  As a function of the control unit 70, the management controller 3 has an initial value data search unit 81 that searches a storage area (cell) in which initial value data is stored from the environmental condition database of the central DB 4, and initial value data from the environmental condition database. A cell extraction unit 82 that extracts cells including control data other than the control data, and a control data update unit 83 that updates initial value data stored in the central DB 4. Specifically, the control data update unit 83 includes a control data comparison unit 84, a control data generation unit 85, and a control data setting unit 86.

  The initial value data search unit 81 is an initial value data storage area in which initial value data prepared in advance from an environmental condition database corresponding to a certain integrated controller among the environmental condition databases 41a, 41b, 41c, etc. of the central DB 4 is stored. Search for. For example, the initial value data search unit 81 searches for a cell in which the initial value data is stored from the environmental condition database 41 a corresponding to the integrated controller 11.

  The cell extraction unit 82 stores data corresponding to the same environmental condition as the environmental condition corresponding to the initial value data storage area from the environmental condition database corresponding to the integrated controller other than the one integrated controller among the environmental condition databases in the central DB 4. A cell that is a region and stores control data other than the initial value data is extracted. Specifically, the cell extraction unit 82 is a cell whose initial condition data is found in the environmental condition database 41a (referred to as cell Ca) from other environmental condition databases 41b, 41c,. A cell in which control data other than value data is stored is extracted.

  The control data update unit 83 updates the initial value data using the control data stored in the extracted cell. Specifically, a control data comparison unit 84, a control data generation unit 85, and a control data setting unit 86 are included.

  The control data comparison unit 84 corresponds to the control data stored in the cell corresponding to the predetermined environmental condition of the one integrated controller and the predetermined environmental condition in the environmental condition database including the cell extracted by the cell extraction unit 82. The control data stored in the cell to be compared is compared. For example, when a cell Cb having the same environmental condition as the cell Ca and storing control data other than the initial value data exists in the environmental condition database 41b, a predetermined cell Cc in the environmental condition database 41a, The cell Cc is compared with the cell Cd of the environmental condition database 41b corresponding to the same environmental condition.

  The control data generation unit 85 generates control data according to the comparison result.

  The control data setting unit 86 controls the control data stored in the environmental condition cell corresponding to the cell in which the initial value data is stored in the environmental condition database including the cell extracted by the cell extraction unit 82 according to the comparison result. The initial value data is updated using. For example, according to the result of comparing the cell Cc and the cell Cd, the initial value data of the cell Ca is updated using the cell Cb of the environmental condition database 41b corresponding to the same environmental condition.

  In addition, the management controller 3 uses, as one function of the control unit 70, the control data group used by the device controller in each of a plurality of environmental conditions from the current environmental condition to the next environmental condition, as an environmental condition database in the central DB 4. And a control data group transmission unit 88 (management controller side control data group transmission unit) that transmits the extracted control data group to the integrated controller 11.

  The control data group extraction unit 87 includes an extracted data comparison unit 871 that compares the control data group used in each of the environmental conditions up to the next environmental condition with the previously extracted control data group.

  The control data group extraction unit 87 has, as a functional configuration, an environmental condition including a control data group extracted this time, that is, a plurality of time zones from a time zone including the current time to a time zone ahead of a predetermined time. In addition, the control data group used by the device controller in an environmental condition including each of the temperature zone including the current temperature and the temperature zones close to and near the temperature zone is extracted to compare the control data group extracted last time. A data comparison unit 871 is provided. In addition, a data calculation unit 872 that calculates control data that does not overlap with control data extracted last time out of the control data group extracted this time based on the comparison result is provided. Then, the control data group transmission unit 88 transmits the calculated control data that does not overlap to the integrated controller 11 (see FIG. 9).

  The management controller 3 having the above-described functional configuration searches for a cell in which initial value data prepared in advance is stored from the environmental condition database corresponding to the integrated controller, and if found, in another environmental condition database, Extract cells with the same environmental conditions that store control data other than initial value data. The management controller 3 updates the initial value data using the control data stored in the extracted cell. In the management controller 3, the initial value data of the control data group used by the device controller is updated in each of the environmental conditions including a plurality of time zones from the time zone including the current time to the time zone ahead of the predetermined time. The control data group extracted from the environmental condition database (for example, the environmental condition database 41a) and transmitted to the integrated controller 11 corresponding to the environmental condition database 41a is transmitted via the network 5. Part of the control data in the control data group is further sent from the integrated controller 11 to the device controller 14. The device controller 14 stores the control data sent from the integrated controller 11 in the control data storage unit, and controls the device based on this control data.

  Therefore, according to the management controller 3 according to the present embodiment, when there is initial value data in the environmental condition database, another storage area of the environmental condition database including the initial value data is set in the same environment of other environmental condition databases. Since the control data can be updated according to the comparison result compared with the storage area corresponding to the condition, even if there is initial value data in the environmental condition database corresponding to a certain integrated controller, the same environment as this initial value data It can be updated to another control data at the time of the condition and transmitted to the device controller. In the device controller, the device can be efficiently operated based on the proven control data, not the initial value data. In addition, when the control data is transmitted, the control data received from the management controller by the device controller via the integrated controller is used by the device controller in each of a plurality of environmental conditions from the current environmental condition to the next environmental condition. Since it is part of the control data group, it is possible to reduce the communication load between the management controller and the integrated controller connected via the network, and the communication load between the integrated controller and the device controller.

  An example of processing in which the management controller 3 searches for initial value data and updates it with control data will be described with reference to the flowchart of FIG.

  In step S1, the management controller 3 determines whether it is a predetermined timing, and collects control data of each device from each store. Specifically, the management controller 3 sends a command for instructing the integrated controller 11 installed in the store 2 to send the control data generated by the device controller.

  In step S2, the management controller 3 collects control data from the integrated controller 11 installed in the store 2 (or an integrated controller (not shown) installed in the store 2a, 2b, etc.), and is in the central DB 4 as necessary. Update the corresponding cell data in the environmental condition database.

  In step S3, the management controller 3 updates the collected control data, and then searches for a cell (for example, a cell Ca) in which initial value data is stored from the environmental condition database corresponding to each integrated controller. If there is a cell Ca in which the initial value data is stored, the process proceeds to step S4.

  In step S4, the management controller 3 uses the same environmental conditions as the cell Ca from the environmental condition database other than the environmental condition database including the cell Ca (for example, the environmental condition database 41a) among the environmental condition databases of the central DB 4. It is determined whether or not there is control data other than the initial value data in this cell. If there is a cell storing control data in step S4, the process proceeds to step S5.

  In step S5, the management controller 3 determines from the environmental condition database including the cell determined in step S4 that the cell Ca and the in-store temperature, the outside air temperature, and the environmental conditions of the time zone match, and the initial value data. When there is a cell Cb in which other control data is stored, a predetermined cell Cc in the environmental condition database 41a is compared with a cell Cd corresponding to the same environmental condition as the cell Cc. For convenience of explanation, it is assumed that the cell Cd exists in the environmental condition database 41b.

  As a result of the comparison, for example, it is determined whether or not the size difference between the control data stored in the predetermined cell Cc and the control data stored in the cell Cd is a predetermined amount (step S6). As an example, there is a method of updating with the value of control data stored in a cell if the value is close, and updating with an average value of a plurality of cells if the difference is large.

  When the difference in the control data is smaller than the predetermined size (step S6: YES), in step S7, the management controller 3 uses the control data in the environmental condition database 41b corresponding to the environmental condition database 41b including the cell Cd. The initial value data of Ca is updated.

  On the other hand, when the difference in the control data is larger than the predetermined size (step S6: No), in step S8, for example, the management controller 3 calculates the average value of all the cells in the corresponding environmental condition in another environmental condition database. Control data used for updating. The initial value data of the cell Ca is updated using this control data average value.

  In step S9, the management controller 3 extracts control data to be transmitted next time. That is, the control data group used by the device controller in each of a plurality of environmental conditions from the current environmental condition to the next environmental condition is compared with the previously extracted control data group, and the previously extracted control data Select control data that does not overlap with.

  In step S10, the management controller 3 transmits the selected control data to the integrated controller of the corresponding store. Here, in addition to the control data of the cell Ca, control data around the environmental condition may be transmitted.

  FIG. 9 is a schematic diagram illustrating a control data group transmitted from the management controller 3 to the integrated controller. The management controller 3 can transmit the current corresponding temperature and the cells before and after the temperature by taking into account some fluctuations with respect to the temperature, for example, with the data calculation unit 872 as a reference. Regarding the time, only the control data group corresponding to the latest environmental condition after the current time is transmitted to the integrated controller. FIG. 9 shows a case where all the environmental condition databases of the integrated controller or the device controller connected to the integrated controller are initial value data. At this time, for example, when the current environmental conditions correspond to an in-store temperature of 15 to 20 ° C., an outside air temperature of 15 to 20 ° C., and a time zone of 16:00 to 18:00, the management controller 3 executes the processing shown in FIG. Then, for the temperature, three cells of 10 to 25 ° C. are transmitted to the integrated controller, and for the time zone, only two cells from 16:00 to 18:00 and 18:00 to 20:00 are transmitted to the integrated controller. Therefore, the management controller 3 transmits a control data group for a total of 18 cells to the integrated controller whose corresponding cells are all initial value data. However, a cell for which control data already exists in the integrated controller is not transmitted.

  FIG. 10A is a schematic diagram illustrating an example of control data transmitted from the management controller to the integrated controller at time Ta (for example, 16:00), and FIG. 10B illustrates time Tb. It is a schematic diagram explaining an example of the control data transmitted from the management controller to the integrated controller in (18:00 as an example). For example, as shown in FIG. 10, control data as shown in FIG. 10A is transmitted from the management controller 3 at time Ta (16:00). That is, control data for a total of 18 cells is transmitted for three cells at an outside air temperature of 10 to 25 ° C., three cells at an in-store temperature of 10 to 25 ° C., and two cells in a time zone.

  Thereafter, if the environmental conditions change and the outside air temperature reaches 20 to 25 ° C. and the in-store temperature reaches 20 to 25 ° C. at time Tb (18:00), the control data group transmitted from the management controller 3 at 18:00 is This is a control data group to which control data for a total of 18 cells of 3 cells of outside air temperature 15-30 ° C. × 3 cells of in-store temperature 15-30 ° C. × 2 cells of time zone should be transmitted. The control data of the cells shown by diagonal lines (one cell in the time zone from 18:00 to 20:00, 4 cells of the outside air temperature 15 to 25 ° C. and the in-store temperature 15 to 25 ° C.) has already been transmitted from the management controller 3. Therefore, the management controller 3 has only to transmit the remaining 14 cells that do not overlap with the previously extracted control data group at time Tb.

(Action / Effect)
In the device control system 1 shown as the first embodiment, the management controller 3 updates and updates the corresponding cell in the environmental condition database in the central DB 4 based on the control data sent from the device controller via the integrated controller. The control data stored in the cell or the updated control data and the minimum control data belonging to the surrounding environmental conditions are transmitted to the store (integrated controller). Therefore, it is possible to reduce a communication load when transmitting / receiving control data between a large number of stores in order to perform control for efficiently operating a plurality of devices installed in the store in cooperation. The storage unit for storing control data provided in the device controller may have a capacity capable of storing a minimum data size.

In the second embodiment, configurations having the same functions as those in the first embodiment are denoted by the same reference numerals and detailed description thereof is omitted.

(Central database)

Have environmental condition databases 91a, 91b, 91c,... The environmental condition database is set for each integrated controller that integrates the device controllers (that is, for each store). In addition, there is a device number database 92 in which the number of devices connected to the device controller integrated by the integrated controller is associated with each integrated controller. The boundary condition database and the device number database may be logically separated from the storage area of the storage medium, or may be prepared as storage media physically divided individually.

  FIG. 11 is a diagram schematically showing the structure of the central DB 90. The environmental condition database 91a corresponds to the environmental condition database 41a. That is, the device controllers 14, 15, 16, 17, 18, 19 integrated by the integrated controller 11 of the store 2 are the showcase 20, the compressor 21, the condenser 22, the air conditioning indoor unit 23, the compressor 24, and the condenser. Control data when operating each device such as 25 in cooperation is stored. The environmental condition database 91b stores control data used by the device controller integrated by the integrated controller installed in the store 2a (not shown). In addition, the environmental condition database 91c stores control data used by a device controller integrated by an integrated controller installed in a store 2b (not shown). The environmental condition databases 91a, 91b, 91c can be described with reference to FIG.

  FIG. 12 is an example of a device number table stored in the device number database 92. The device number database 92 stores a table in which the number of devices connected to the device controller integrated by the integrated controller is associated with each integrated controller (that is, for each store). In FIG. 12, specifically, the number of freezing or refrigeration equipment (showcases) is associated with a store. Note that the device number database 92 may store a table in which the types of devices and the number of devices are known instead of the total number of devices connected.

(Functional configuration of management controller)
An example of the functional configuration of the management controller 3 will be described with reference to FIG. As a function of the CPU 71, the management controller 3 extracts the corresponding integrated controller from the device number database 92 of the central DB 90, and the control data corresponding to all cells from the environmental condition database that matches the number of devices. A control data extraction unit 102 to extract and a control data update unit 103 to update the initial value data of the environmental condition database with the extracted control data are included.

  The device number extraction unit 101 refers to the device number database 92 of the central DB 90 and integrates the number of devices corresponding to the number of devices connected to the device controller integrated with the newly connected integrated controller. Extract the controller. Here, the number may be the same, or, for example, integrated controllers having a close number of connections such as a difference of five may be extracted. Further, the control data extraction unit 102 extracts control data corresponding to all cells from the environmental condition database in which the number of devices extracted by the device number extraction unit 101 matches. In addition, the control data update unit 103 updates the initial value data with the extracted control data of all the cells.

  The management controller 3 having the above-described functional configuration searches whether there is another integrated controller (that is, another store) in which the same number of devices as the newly connected integrated controller (or the number of close devices) is installed. be able to. When there is a store where the same number of devices are installed, the control data of the devices can be regarded as similar under the same environmental conditions, and therefore used as control data under the same conditions of this store.

  An example of processing in which the management controller 3 according to the second embodiment updates the environmental condition database will be described with reference to the flowchart of FIG.

  In step S11, the management controller 3 searches the environmental condition database in which all cells of the environmental condition database are initial value data. This process corresponds to searching for a newly opened new store.

  In step S12, the management controller 3 searches for a store where the number of devices installed in the new store is the same or the difference is equal to or less than a predetermined number. As an example, it is checked whether the number of showcases installed in a new store and an environmental condition database of an existing store whose difference is 5 or less (an example) exist in the central DB 90.

  In step S13, when there is an environmental condition database of the corresponding store (step S13: YES), in step S14, the management controller 3 applies the environmental condition database of the corresponding store as the environmental database of the new store.

  On the other hand, if there is no environmental condition database for the corresponding store (step S13: No), in step S15, the management controller 3 determines the environment of the store where the number of connected devices is five or more and the difference in the number of connected devices is the smallest. The condition database is applied as the environment database of the new store, and in step S16, the device count data of the new store is registered in the device count database 92 of the central DB 90.

  Next, in step S17, the management controller 3 transmits control data that matches the current environmental conditions from the applied environmental condition database to the integrated controller of the corresponding store. Here, the minimum control data including the environmental conditions around the current environmental conditions may be transmitted.

(Action / Effect)
In the device control system shown as the second embodiment, the number of devices corresponding to the number of devices connected to the device controller integrated with the newly connected integrated controller is referred to the device number database 92 of the central DB 90. The connected integrated controller is extracted, control data corresponding to all cells is extracted from the environmental condition database in which the number of extracted devices matches, and initial value data is updated with the extracted control data of all cells. According to the device control system according to the second embodiment, it is possible to search whether or not there is another store in which the same number of devices (or the number of close devices) as the newly connected integrated controller is installed. Under the same environmental conditions, the control data of the equipment can be regarded as similar, so if there is a store with the same number of equipment installed, the environmental condition database for the same condition of this store is used as the environmental condition database for the new store. Can be applied.

  Therefore, for example, in a newly opened store or the like, even when only initial value data is prepared, or even when control data is insufficient, the control data of other stores having the same or similar number of installed devices By using this, it is possible to perform efficient operation that matches environmental conditions to some extent.

  Furthermore, at this time, since the minimum control data around the current environmental conditions is transmitted to the device controller, it is used to perform control for efficiently operating a plurality of devices installed in the store in cooperation with each other. Communication load when transmitting and receiving control data between multiple stores can be reduced. The storage unit for storing control data provided in the device controller may have a capacity capable of storing a minimum data size.

  In the device control system shown as the embodiment of the present invention, the control device such as the device controller, the integrated controller, and the management controller and the hardware configuration configuring them can be realized as program modules. Therefore, the processing that is executed in the above-described device controller, integrated controller, management controller, or the like may be executed by any controller. Further, it can be executed by a general-purpose computer having functions of a device controller, an integrated controller, and a management controller.
