  If the time difference is equal to or greater than the log collection status confirmation interval (24 hours) (step S506 “Y”), the node ID is registered in the log collection request list 55 shown in FIG. 6 (step S507).

  That is, every day when the log collection confirmation time set as the management server setting value in the management server 5 is reached, the management server 5 confirms the latest time of the collected logs for all the sensor nodes and exceeds the log collection status confirmation interval. If there is a sensor node 2 for which no log has been collected, the processing (steps S504 to S507) between step S502 and step S508 for registering the node ID in the log collection request list 55 is repeated to automatically log the log collection status. After performing the confirmation process, the management server 5 determines whether or not the node ID is registered in the log collection request list 55 shown in FIG. 6 (step S509).

  If the time difference is not greater than or equal to the log collection status confirmation interval (step S506 “N”), the process proceeds to step S508.

  In the present embodiment, a sensor node 2 for measuring temperature and humidity is installed in each farmland of the customer's 10 farm, and the worker 1 who performs the farm work is attached with the mobile node (name tag sensor node) 4. This will be described below.

  When the worker 1 approaches the sensor node 2 installed in the farmland (work area A), a log (log information) transmission request is issued from the mobile node 4 to the sensor node 2, and the log of the sensor node 2 is sent to the mobile node 4. Record.

  Next, when the worker 1 returns to the office (management area B), the log of the sensor node 2 is sent from the mobile node 4 to the management server 5 installed in the office via the wireless access point device 3.

  After transmitting the sensor node 2 log, the sensor node 2 log is deleted from the mobile node 4.

  When it is desired to change the log collection interval of the sensor node 2, the administrator 71 of the operation agency 72 instructs the management server 5 to change the setting value of the log collection interval at the administrator terminal 7.

  The management server 5 creates a setting file based on an instruction from the administrator terminal 7 and transmits the created setting file to the mobile node 4 of the worker 1 in the office (management area B).

  The mobile node 4 records the setting file in the recording unit.

  When the worker 1 goes to work on the farmland (work area A), the setting file is transmitted from the mobile node 4 to the sensor node 2, and the setting file is applied to the sensor node 2.

  After the setting file is applied, the setting file is deleted from the mobile node 4.

  Every day, when the time set in the management server 5 (7:00) is reached, the latest time of the collected logs is confirmed for all sensor nodes, and the sensor node 2 for which logs have not been collected for more than one day (24 hours) If there is, the installation location of the sensor node 2 where log collection is not performed is notified to the customer and the manager 71 of the operation agency 72 by e-mail.

  Further, the administrator 71 of the operation agency 72 inquires the management server 5 about the log collection status, and confirms the node ID and the installation location of the sensor node 2 for which log collection has not been performed for one day (24 hours) or more. be able to.

  When transmitting the configuration file, the management server 5 records the transmitted configuration file name and the time when the configuration file application is instructed, and confirms that the configuration file has been applied by the sensor node 2. The success is recorded in the set value management database 53.

  The administrator 71 of the operation agency 72 can check the setting file application status by inquiring the management server 5 about the setting file application status.

  In this embodiment, the sensor node 2 can be remotely managed even in an environment where the measurement site cannot be connected to the Internet.

  Furthermore, in the present embodiment, log collection of the sensor node 2 can be performed without the worker 1 carrying the mobile node 4 being conscious.

  Also, even if there is a log collection omission, the administrator terminal 7 knows from which sensor node 2 the log is not collected, so that log collection can be instructed.

  Similarly, the administrator terminal 7 can grasp the application status of the batch file or processing file describing the processing sent from the management server 5 to the sensor node 2.

  The operation management service system of the present invention can remotely manage the sensor node 2 without dispatching a person from the operation agency 72 even in an environment where the measurement site cannot connect to the Internet.

  Further, the log collection status and the setting file distribution status can be centrally managed by the administrator terminal 7 of the operation agency 72.
