Description

  The present invention relates to a switchboard having a function of determining whether or not a pre-contracted electrical device is connected, and in particular, a switchboard having a function of determining whether or not an electrified kitchen device defined by a contract is connected. (Power panel)

  In recent years, kitchen appliances that use electricity (hereinafter referred to as “electric appliance appliances”) instead of kitchen appliances that use gas as fuel have become widespread in restaurants, restaurants, and the like (see Non-Patent Document 1).

  In general, a store using an electric kitchen device for business purposes has concluded a so-called electric device use contract with an electric power company in order to receive a discount on the electric charge. For example, when the total capacity of electrified kitchen equipment is 30 kW or more, a discount on the electricity charge is received when an electric equipment use contract is concluded (see Non-Patent Document 2).

  When concluding this electric equipment use contract, the person in charge of the electric power company visits the site such as a store and checks whether or not the predetermined condition defined in the electric equipment use contract is satisfied. If the electric power company determines that this condition is satisfied, the electric power company concludes a contract, and a switchboard dedicated to the electric equipment use contract is provided at a site such as a store (see Non-Patent Document 2). Then, it is necessary to check whether or not the site such as the store with which the contract is concluded adheres to the predetermined condition at a predetermined cycle (for example, every month, every year). In other words, after the contract is concluded, it is necessary to confirm whether or not the state does not meet the predetermined condition by increasing the number of electrified kitchen devices or reducing the number of electrified kitchen devices.

  In this way, since the electric equipment use contract is a special contract, the electric power company personnel periodically visit the site to determine the target electric equipment connected to the switchboard for the electric equipment subject to the electric equipment usage contract. Need to do.

In the following description, an electric kitchen device used for business will be described as an example of an electric device. However, the electric switchboard according to the embodiment of the present invention is similarly used for an electric device other than the electric kitchen device. be able to.

  The switchboard 11 of the present embodiment is a switchboard dedicated to an electric equipment use contract, and is one or more electrified kitchen equipment (hereinafter referred to as “target electric equipment”) 12-1 to 12 -N (specified in the electric equipment use contract) ( N is an integer greater than or equal to 1) and is connected to a distribution line (not shown), and supplies power to the target electrical devices 12-1 to 12-N via the distribution line. Examples of the target electrical devices 12-1 to 12-N include a range, an oven, a fryer, a boiling pot, a disinfection device, and a cleaning device.

  As shown in FIG. 1, the switchboard 11 is provided with a door (not shown), and the door is usually locked. The switchboard 11 with the door opened includes a plurality of switch units 11-1 to 11-M (M is an integer of 2 or more and M> N). All the switch units 11-1 to 11-M function as connection means. Power is supplied to the switchboard 11 from an electrical supplier, and the power supplied to the switchboard 11 is the target electrical device 12-via any one of the plurality of switch units 11-1 to 11 -M of the switchboard 11. 1 to 12-N. In the illustrated example, N = 3 and M = 12, and the target electrical devices 12-1 to 12-3 are connected to the switch units 11-1 to 11-3, respectively.

  The switchboard 11 is disposed as a switchboard dedicated to the electric equipment use contract at a store etc. that has been installed at an electrical equipment use contract after removing a general power distribution board that has been installed until then. The When an electric equipment use contract is concluded, an electrified kitchen apparatus subject to the electric equipment use contract is specified, and when a new electric equipment is added, the contract is changed.

  Specifically, when an electric equipment use contract is concluded between the electric power company and an electric equipment usage contractor, the person in charge of the electric power company arranges a new switchboard 11 dedicated to the electric equipment usage contract in a store or the like. In addition, information (hereinafter referred to as “device information”) for identifying the target electrical devices 12-1 to 12-3 is registered in the memory 22 of the switchboard 11 described later.

  FIG. 2 is a block diagram showing the configuration of the switchboard 11. The switchboard 11 includes a microcomputer (CPU) 21, a memory 22, power measuring units 23-1 to 23-M, and connector units 24-1 to 24-M. In the memory 22, device information of the target electric devices 12-1 to 12-N is registered in association with the switch units 11-1 to 11-M. Thereby, the information of the switch unit connected to the specific target electrical devices 12-1 to 12-N among the switch units 11-1 to 11-M is registered in the memory 22.

  The power measuring units 23-1 to 23-M correspond to the switch units 11-1 to 11-M, respectively. The power measuring units 23-1 to 23-M measure the current or power flowing through the switch units 11-1 to 11-M, respectively, and supply the measured data to the CPU 21. Then, the CPU 21 stores measurement data in the memory 22 in association with the switch units 11-1 to 11 -M, that is, the target electrical devices 12-1 to 12 -N. The memory 22 has a capacity capable of storing measurement data of about 90 days, for example. In the memory 22, device names such as a range, an oven, a fryer, a cooking pot, a disinfection device, a cleaning device, and the equipment capacity of the target electric device, that is, electric capacity (kW) are registered as device information.

  The connector units 24-1 to 24-3 are connectors that are connected to connectors of information devices (not shown) such as handy terminals possessed by persons in charge of the electric power company. The handy terminal or the like performs data retrieval by sequentially connecting to the connector units 24-1 to 24-3 corresponding to the switch units 11-1 to 11-3 of the target electrical devices 12-1 to 12-3 to be determined. It is.

  FIG. 3 is a flowchart for explaining the operation of the switchboard 11. Referring to FIGS. 2 and 3, the person in charge of the power company installs the switchboard 11 in a store or the like, and sets the target electrical devices 12-1 to 12-3 to the switch units 11-1 to 11 -M, respectively. Connect (step S1).

  Next, the person in charge of the electric power company separately connects an information device such as a handy terminal to one of the connector sections 24-1 to 24-M, and stores the device information of the target electric devices 12-1 to 12-3. For example, the information is input to the CPU 21 in association with the switch numbers of the switch units 11-1 to 11-3. As a result, the CPU 21 records the device information in the memory 22 in association with the switch number (step S2).

  When the switchboard 11 becomes ready for operation (step S3), power is supplied from the switchboard 11 to the target electrical devices 12-1 to 12-3. And electric power measurement part 23-1 to 23-M measures the electric power used by object electric equipment 12-1 to 12-3 (Step S4). The power usage of the target electrical devices 12-1 to 12-3 measured by the power measuring units 23-1 to 23-M is given to the CPU 21 as measurement data via an A / D converter (not shown). It is done.

  Since the correspondence between the switch number and the power measuring units 23-1 to 23-3 is set in advance in the CPU 21, the CPU 21 stores measurement data in the memory 22 in association with the switch number (step S5). As a result, device information, that is, measurement data is stored in the memory 22 in association with the target electric device.

  When the person in charge of the electric power company determines the target electric device (step S6), an information device (not shown) such as a handy terminal is used to switch the target electric devices 12-1 to 12-3 that perform the determination. Data is searched by sequentially connecting to the connector sections 24-1 to 24-3 corresponding to 11-1 to 11-3 (step S7).

  When the CPU 21 receives the data search, it reads out the measurement data corresponding to the switch number from the memory 22 and displays it on the information device (step S8). As described above, since the equipment capacities of the target electrical devices 12-1 to 12-3 connected to the switch units 11-1 to 11-3 are specified, the measurement data of the information device is the switch unit 11-1. ~ 11-3 is notified to the person in charge of the electric power company that it is different from the stored equipment capacity (for example, when the measurement data exceeds the equipment capacity: step S9). The person in charge of the power company looks at the display of the information device, and an electrical device other than the target electrical device determined by the electrical device use contract (that is, the non-target electrical device) is connected to the switch units 11-1 to 11-3. (Contract violation: step S10).

  As described above, the CPU 21 ends the determination of all the target electric devices 12-1 to 12-N (step S11), that is, when the data search is completed, the CPU 21 stores the measurement data stored in the memory 22. Reset and erase (step S12). Then, the person in charge notifies the store side whether or not there has been a breach of contract in accordance with the determination result (step S13). In addition, although the door of the switchboard 11 is locked, for example, the store side arbitrarily connected another electric kitchen equipment to a switch unit other than the switch units 11-1 to 11-M currently used. However, since the CPU 21 turns off the switches other than the switch corresponding to the registered device information, even if the store side arbitrarily connects another electric kitchen device, the electric kitchen device cannot be used.

  In this way, the person in charge of the electric power company can acquire measurement data from the switchboard and determine whether or not the electric equipment use contract is adhered to according to the measurement data. Even so, the determination can be made and the cost can be reduced. Furthermore, there is no temporary power outage and no need to enter the kitchen, so there is no risk to the sanitary environment.

  The distribution board 11 and the target electrical devices 12-1 to 12-3 each include a plurality of communication devices having a communication function, and the communication device of the distribution board 11 and the communication devices of the target electrical devices 12-1 to 12-3 If the device information is transmitted from the target electrical devices 12-1 to 12-3 by the switchboard 11 so that the device information is registered by the communication line, the CPU 21 immediately confirms whether or not the device information is registered. It is possible to confirm the unauthorized connection. Further, if the switchboard 11 is connected to a server of an electric power company via a network or the like, the target electric device can be determined online.

  As described above, according to the present embodiment, not only the determination work can be made more efficient, but also the cost can be reduced, and there is no fear of interrupting the work of the contract contractor. Furthermore, since it is not necessary to enter the kitchen, no consideration is given to the sanitary environment.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.
