The data transfer terminal 78 is a device corresponding to the data transfer unit 23 of FIG.

  FIG. 8 is a flowchart showing the operation of the management apparatus in this embodiment.

  First, the operation at the time of data update will be described.

  When updating the facility data 300, the monitoring control device 76 sends a data update notification indicating that the data has been updated to the difference detection unit 77 (step 200). The data update notification includes, for example, the equipment ID number of the updated location of the equipment data 300 and information indicating the data type.

  The difference detection unit 77 acquires the equipment ID number and the data type from the data update notification received from the monitoring control device 76 (step 201). The difference detection unit 77 preliminarily manages data update information 301 that records the location where the facility data is updated.

  FIG. 9 is a diagram illustrating an example of the data update information. In this example, the equipment data includes state data and management data. The state data indicates the state of the equipment such as the presence or absence of an alarm, and is mainly a monitoring target. The management data indicates equipment attributes, parameters, and the like, and is mainly a setting target. Referring to the data update information in FIG. 9, whether or not each item of status data and management data has been updated is set corresponding to an ID number (equipment device ID (Identification) number) for identifying the facility device. . In the data update information in this example, an updated item is indicated by “1”, and an item that has not been updated is indicated by “0”.

  The difference detection unit 77 searches the data update information 301 using the equipment ID number acquired from the data update notification as a key, and sets that the data has been updated at a location corresponding to the acquired data update content (step 202). . The data update information 301 is generated by the above operation.

  Next, an operation when generating the transfer target data 302 will be described.

  Here, as an example, generation of transfer target data is periodically started by a timer. When the difference detection unit 77 is activated by the timer (step 203), first, the data update information 301 is acquired (step 204).

  Next, the difference detection unit 77 refers to the data update information 301 and extracts a portion changed from the previous transfer of the facility data 300 (step 205). Next, the difference detection unit 77 generates the transfer target data (difference data) 302 of the changed part (step 206). The transfer target data 302 is generated by the above operation.

  When the generation of the transfer target data 302 is completed, the difference detection unit 77 transmits a transfer target data generation completion notification to the data transfer terminal 78 (step 207). When the transfer of the transfer target data to the data transfer terminal 78 is completed, the difference detection unit 77 clears all values of the data update information 301 to “0” as an initialization process.

  Upon receiving the transfer target data generation completion notification, the data transfer terminal 78 transfers the transfer target data 302 to the information providing server 79 via the network 74 (step 208).

  Although not shown in the drawings, the difference detection unit 77 transfers all equipment data to the information providing server 79 at the first transfer after the monitoring control device 76 is started or restarted.
