<Configuration of Equipment Management System According to First Embodiment>
The configuration of the equipment management system according to the first embodiment of the present invention will be described with reference to FIG.

  An equipment management system 1A according to the present embodiment includes indoor units 10-1, 10-2, and 10-3 of air conditioners that are equipment to be managed, and these indoor units 10-1 to 10-3. Outdoor units 20-1 to 20-4 of so-called multi-type air conditioners that supply refrigerant to a plurality of indoor units, and a first management device connected to the outdoor units 20-1 to 20-4 via a fieldbus 30 40A and a second management device 60A connected to the first management device 40A via the network 50. In the present embodiment, only the indoor units 10-1 to 10-3 connected to the outdoor unit 20-1 are shown as indoor units in the equipment management system 1A for the sake of simplicity. A plurality of indoor units are also connected to the outdoor units 20-2 to 20-4.

  The first management device 40A includes a user interface unit 41, a schedule management unit 42, a device monitoring control unit 43, a first energy management unit 44, and a load distribution management unit 45A. These user interface unit 41, schedule management unit 42, device monitoring control unit 43, first energy management unit 44, and load distribution management unit 45A each operate as an independent module, and have internal sockets (IP address, port number). And communication with each other using Web services such as BACnet / WS. In the initial state, these modules do not exist in the second management device 60A.

  The user interface unit 41 includes, for example, a touch panel provided with an operation unit and an image display unit, and is operated by an administrator who is a user of the facility equipment management system 1A, and the indoor units 10-1 to 10-3 and the outdoor unit 20-1. Enter information manipulated for monitoring and control of ~ 20-4. In addition, the user interface unit 41 outputs information related to monitoring and control of the indoor units 10-1 to 10-3 and the outdoor units 20-1 to 20-4 to the administrator.

  The schedule management unit 42 includes schedule information for monitoring and controlling the indoor units 10-1 to 10-3 and the outdoor units 20-1 to 20-4 among the information input from the user interface unit 41, for example, It stores schedule information for changing the set temperature and switching the power ON / OFF at a preset time.

  The equipment monitoring control unit 43 monitors and controls the indoor units 10-1 to 10-3 and the outdoor units 20-1 to 20-4 according to the schedule information stored in the schedule management unit 42.

  The first energy management unit 44 is based on information related to the monitoring and control of the indoor units 10-1 to 10-3 and the outdoor units 20-1 to 20-4 performed by the device monitoring control unit 43. The energy consumption for every 1 to 10-3 and for each predetermined period is calculated and sent to the user interface unit 41. Here, each of the outdoor units 20-1 to 20-4 and the indoor units 10-1 to 10-3 constantly detects or calculates individual power consumption. The device monitoring control unit 43 receives this power consumption data at short time intervals. Since the target air conditioner is a multi-type in which one outdoor unit is connected to a plurality of indoor units, the energy consumption for each of the indoor units 10-1 to 10-3 is 10 -1 to 10-3 itself, the power consumption of the outdoor unit 20-1, and the cooling / heating output (capacity) of each of the indoor units 10-1 to 10-3 connected to the outdoor unit 20-1. A method of adding values prorated by the ratio is used.

  The load distribution management unit 45A monitors the CPU occupancy (operation) rate and the occupancy time due to the processing being executed by the CPU (arithmetic processing unit) of the first management device 40A, and sets a threshold at which the CPU occupancy rate is set in advance for a predetermined time. If it is determined that it exceeds the above, the program module for executing the function of the first energy management unit 44 is copied and transmitted to the second management device 60A. As described above, the first energy management unit 44 calculates the energy consumption for each of the indoor units 10-1 to 10-3 and for each predetermined period, and then each of the outdoor units 20-1 to 20- in a short cycle. 4 and the indoor units 10-1 to 10-3... Are calculated and integrated, so that the processing load on the CPU is very heavy. In addition to this, when troublesome processing occurs in the schedule management unit 42, the user interface unit 41, etc., the CPU occupancy rate continues to be high.

  As will be described later, the load distribution management unit 45A accesses the second energy management unit 62 newly generated in the second management device 60A notified from the second management device 60A by transmitting the program module. The IP address and the port number of the first energy management unit 44 held in advance in the user interface unit 41, the schedule management unit 42, and the device monitoring control unit 43 are rewritten with the IP address and the port number.

  The second management device 60A has a function management unit 61A.

  When the function management unit 61A receives the program module for executing the function of the first energy management unit 44 from the first management device 40A, the function management unit 61A executes the received second program module in the second management device 60. A part 62 is generated. In addition, the function management unit 61A notifies the first management device 40A of the IP address and port number for accessing the generated second energy management unit 62.

<Operation of the equipment management system according to the first embodiment>
Next, the operation of the equipment management system 1A according to the present embodiment will be described with reference to the sequence diagram of FIG.

  First, when the administrator inputs information operated for monitoring and control of the air conditioner indoor units 10-1 to 10-3 and the air conditioner outdoor units 20-1 to 20-4 from the user interface unit 41 (S1). Of these pieces of information, schedule information relating to monitoring and control is stored in the schedule management unit 42 (S2).

  Next, according to the schedule information memorize | stored in the schedule management part 42, monitoring and control of the indoor units 10-1 to 10-3 and the outdoor units 20-1 to 20-4 are executed by the equipment monitoring control unit 43 (S3). If necessary, monitoring information of each indoor unit and each outdoor unit is acquired, and control information generated accordingly is sent to the corresponding indoor unit and outdoor unit. Information relating to monitoring and control executed in this way is transmitted to the user interface unit 41, displayed, and provided to the user (S4). In each indoor unit and each outdoor unit, the operation is controlled based on the control information sent from the device monitoring control unit 43.

  In the state where the control is performed in this way, the first energy management unit 44 monitors the indoor units 10-1 to 10-3 and the outdoor units 20-1 to 20-4 performed by the device monitoring control unit 43. And based on the information regarding control, the energy consumption for every indoor unit and every predetermined period is calculated (S5). The calculated energy consumption for each indoor unit and for each predetermined period is sent to the user interface unit 41 (S6).

  While the monitoring control of the indoor units and the outdoor units and the calculation of the energy consumption are executed in this way, the load distribution management unit 45A monitors the CPU occupation rate and the occupation time by the processing of the first management device 40A ( S8).

  When it is determined that the CPU occupancy exceeds a preset threshold value for a predetermined time or more, the program module for executing the function of the first energy management unit 44 is copied by the load distribution management unit 45A, and the second management It is transmitted to the device 60A (S9).

  In the second management device 60A, the program module transmitted from the first management device 40A is received by the function management unit 61A, and a second energy management unit 62 that executes the received program module is generated in the second management device 60. Is done. Then, the generated IP address and port number for accessing the second energy management unit 62 are notified to the first management device 40A (S10).

  In the first management device 40A, the IP address and port number for accessing the second energy management unit 62 transmitted from the second management device 60A are received. With the IP address and port number, the user interface unit 41, The IP address and port number of the first energy management unit 44 held in advance in the schedule management unit 42 and the device monitoring control unit 43 are rewritten (S11).

  By executing the processing in this way, the user interface unit 41, the schedule management unit 42, and the device monitoring control unit 43 are switched to access the second energy management unit 62 instead of the first energy management unit 44. Then, the second energy management unit 62 starts monitoring and controlling the indoor units 10-1 to 10-3 and the outdoor units 20-1 to 20-4. As described above, the energy management is a process that requires a heavy load on the CPU to calculate and accumulate the power consumption of each outdoor unit and indoor unit in a short cycle, but this energy management process needs to be performed. In the first management device 40A in which there is no more, the processing load on the CPU is greatly reduced.

  According to the first embodiment described above, the first management device 40A is distributed by distributing the functions of the first management device 40A to the second management device 60A when the CPU in the first management device 40A becomes heavily loaded. Thus, the processing can be executed normally.

  In step S9 of the first embodiment described above, when the load distribution management unit 45A determines that the CPU occupancy exceeds a preset threshold value for a predetermined time or more, a part of the function of the first energy management unit 44 is performed. A program module for execution, for example, a program module for executing monitoring control of 50 of the 100 air-conditioning indoor units to be monitored and controlled, is copied and transmitted to the second management device 60A. Also good.

  In this case, in step S11, instead of rewriting the IP address and port number of the first energy management unit 44 held in advance in the user interface unit 41, the schedule management unit 42, and the device monitoring control unit 43, the second energy management is performed. Processing for adding the IP address and port number of the unit 62 is performed.

  In this way, by distributing only a part of the functions of the first energy management unit 44 to the second management device 60A, the load on the first management device 40A can be reduced and the processing can be executed normally.

  In the first embodiment described above, a program module for executing functions of a plurality of functional units including the first energy management unit 44 in the first management device 40A is copied and transmitted to the second management device 60A. Further, more functions may be transferred to the second management device 60A.

  In addition, after the function of the first energy management unit 44 is transferred to the second management device 60A, the CPU occupation rate is set in advance based on the CPU occupation rate and the occupation time monitored by the first management device 40A. If the state lower than the threshold value (a value lower than the above-mentioned threshold value) continues for a second predetermined time (a value significantly larger than the above-mentioned predetermined time) or more, the function transferred to the second management device 60A is changed to the first energy. You may make it return to the management part 44. FIG.
