(Operation of the first embodiment)
The operation of the monitoring controller according to the first embodiment of the present invention will be described below with reference to FIGS.

  FIG. 4 is a flowchart showing a restart operation at the time of factory shipment of the sensor server according to the first embodiment of the present invention.

  First, in the factory-shipped state, the storage area of the SRAM 311 in which zero data is stored is divided, the operating system storage area 311A is the operating system, the program storage area 311B is the program, and the setting file storage area 311C is the default setting file. Is installed (s10).

  Next, the sensor server 10 is operated and restarted (s11). The main control unit 300 of the sensor server 10 reads the backup list 311H stored in each storage area of the SRAM 311 and refers to the time stamp at the time of file creation in the backup list 311H (s12).

  Since the backup file does not exist at the time of the initial restart, the main control unit 300 recognizes that no data exists in the flash memory 312 by referring to the backup list 311H. After the recognition, the main control unit 300 copies the data in the SRAM 311 to the flash memory 312 and executes backup (s13).

  Next, the main control unit 300 saves detailed backup data including the file name, data capacity, and time stamp of the data backed up from the SRAM 311 to the flash memory 312 in the backup list 311H (s14).

  FIG. 5 is a flowchart showing the restarting operation of the sensor server according to the first embodiment of the present invention.

  First, the main control unit 300 reads the restart setting time from the setting file storage area 311C in the SRAM 311 and refers to the time information transmitted by the clock circuit 302 (s20). The same operation is repeated until the set time is reached (s20; NO), and when the set time is reached (s20; YES), the sensor server 10 is restarted (s21).

  Next, the main control unit 300 refers to the backup list 311H (s22) and collates with the time stamp of each file stored in the SRAM 311 (s23). If there is a discrepancy between the backup list 311H and the time stamp (s24; YES), first, a file that has been deleted from the SRAM 311 due to a certain problem although it is backed up in the flash memory 312 is restored (s25).

Next, when there is no discrepancy between the backup list 311H and the time stamp (s24; NO), or after executing s25, new and changed data is updated from the SRAM 311 by operations such as update storage, addition, and deletion after the previous backup. Back up to the flash memory 312 (s26). At this time, the operating system storage area 311A, the program storage area 311B, and the setting file storage area 311C are newly backed up only for the change, and all other files are backed up to the flash memory 312. Next, a backup list based on the backup operation performed in s26 is created, and the backup list 311H is updated (s27).
(Effects of the first embodiment)
According to the above-described embodiment, the sensor server 10 is operated by the data stored in the SRAM 311 and the backup data is stored in the flash memory 312, so that the volatile memory is used due to an unexpected situation such as power supply being stopped. Even if the data in the SRAM 311 is lost, the data can be recovered.

  In addition, since the SRAM 311 performs reading and writing operations faster than the nonvolatile memory, the processing speed of normal operation and restart is improved. Further, since only the backup list 311H and the header information in the SRAM 311 are referred to for data verification, and all data is not read, the time required for restart is shortened.

Further, by periodically restarting, maintenance of a temporary storage memory (not shown) installed in the main control unit 300 of the sensor server 10 can be performed, and the operational stability of the sensor server is improved.

In the following description, parts having the same configuration and function as those of the first embodiment are denoted by common reference numerals.

  The SRAM 311 has an extended log file storage area 311I for storing measurement information such as temperature and humidity measured by each sensor. The flash memory 312 has a backup area 312I for backing up and storing the extended log file storage area 311I.

  The backup operation of the extended log file storage area 311I is performed by mirroring instead of backup only for the update.

The extended log file storage area 311I is divided into 15 storage areas each having a capacity of 64 KB. By setting the temperature and humidity measurement data per day to, for example, 64 KB, a maximum of 15 days can be stored. Logs can be saved. In addition, logs are repeatedly stored in order in each storage area numbered from 1 to 15, and the latest 15 days of logs can always be held by storing the latest writing position with a pointer.
(Effect of the second embodiment)
According to the above-described embodiment, in addition to the effects of the first embodiment, the extended log can be saved and backed up in the same manner as the mail log file and the alarm log file, so that the monitoring controller can only monitor as security. In addition, since data can be measured, a more detailed monitoring system can be established.
