The best mode for carrying out the present invention will be described.
Embodiments of a monitoring device, a communication device, and a monitoring system according to the present invention will be described below with reference to the drawings.

  FIG. 1 shows an overall configuration of a manhole pump monitoring system as an example of a system in which the present monitoring system is used. The monitoring device 200 installed in the monitoring room 300 communicates with the communication terminals 501 to 503 installed in each machine via the telephone line 400, and the manhole pump (monitoring target) accumulated in the communication terminals 501 to 503. The driving information of 507 to 509 is acquired. Further, when an abnormality occurs in the manhole pumps 507 to 509, the communication terminals 501 to 503 issue an alarm to the monitoring device 200 through the telephone line 400, and the monitoring device 200 that has received the alarm receives the client via the LAN 301. An alarm is notified to the user by displaying it on the screen of the personal computer 302 or the like.

  FIG. 2 shows the configuration of the monitoring device 200. The monitoring device 200 includes communication devices (1) to (3) 201 to 203, switches 208 and 209, an input / output device 211, HDDs (1), (2) 213 and 214, a LAN 301, and the like. The communication devices (1) to (3) 201 to 203 have a CPU, a modem, a memory, a flash memory, and the like that execute a monitoring program, communicate with the communication terminals 501 to 503, and via the input / output device 211. The operations of the switches 208 and 209 are controlled, and the acquisition information and the like are recorded in the HDDs (1), (2) 213, and 214.

  The switches 208 and 209 turn on / off the magnetic storage devices 213 and 214.

  Under the control of the communication device 1 (201), the input / output device 211 instructs the operation of the switches 208 and 209, and turns on / off the buzzer 207 and the operating lamp 206. The start / stop is performed by the start / stop button 212. Although the input / output device 211 is separated from the communication device 1 (201), the input device and the output unit of the input / output device 211 are provided in the communication device 1 (201), and the communication device 1 (201) enters the input / output device 211. It is also possible to output.

  The HDDs 1 and 2 (213 and 214) are magnetic recording devices that record information acquired by the communication devices 201 to 203. The LAN 301 connects the communication devices 201 to 203 to the HDDs (1), (2) 213 and 214. The LAN 301 can be connected to a personal computer 302 outside the monitoring device 200.

An example of the data backup operation in the embodiment will be described.
(1) When the day changes (around 0:30 in the night), data is backed up from HDD1 to HDD2. Only the data collected through communication is backed up, not the program.
(2) The data to be backed up has the names of backup 1 and backup 2, and rewrites backup 1 on that day. On the next day, the backup 2 is rewritten. Thereby, it is possible to prevent data from being lost when the backup operation fails.
(3) Factory default data in the HDD includes a program so that the HDD 1 and the HDD 2 have equivalent data. As a result, when the HDD 1 fails, it can be replaced with the HDD 2. The HDD 2 is turned on only at the time of backup, and the life of the HDD can be extended.

The power ON time of HDD1 and HDD2 in the embodiment will be described with reference to FIGS.
(1) The power supply of the HDD 1 is automatically turned on from 8:50 to 18:00 so that the operator can operate in the daytime to improve the response of the HDD (601 in FIG. 3).
(2) When copying data from HDD1 to HDD2, both HDD1 and HDD2 are powered on. 602 in FIG. 3 and 612 in FIG. When making a product, it is preferable that the time for copying data is an operation of about 1 hour immediately after the change of day (0:30).
(3) When the operator searches the history data, the HDD 1 is turned on. 603 in FIG. 3 is an example when there is an extreme phenomenon at night and a history is searched. When searching between 8:50 and 18:00 (604 in FIG. 3), the HDD 1 is already powered on, so there is no need to turn it on again.
(4) Polling operates for about 2 hours from around 3:30 at night. 605 in FIG. An example of polling details time is shown in FIG.
(5) Alarm reception: When an alarm is received from the communication terminal, the HDD 1 is turned on at 606 in FIG. 3 at night to record the alarm history. During daytime, it is not necessary to turn on the power as in 607.
(6) Summing up the power ON times of the HDD 1 as described above, it can be shown as 608, 609, 610, 611 in FIG. 3, and the operation rate of the HDD 1 can be reduced (the operation rate of about 60% in actual use). it is conceivable that).
(7) The HDD 2 is energized when copying data from the HDD 1 to the HDD 2 as indicated by reference numeral 612 in FIG. In actual use, it is considered to be about 1 hour.

Described below is how to prevent the number of power on / off times of the HDD from becoming excessive in the embodiment.
(1) If alarms occur frequently, 606 in FIG. 3 may occur frequently. For example, a high water level alarm frequently repeats the generation and recovery of an alarm when the water level fluctuates near the high water level.
(2) To prevent this, the HDD power-off time is delayed, and even when alarm history writing or data retrieval is completed, the HDD is turned off for about 30 minutes to prevent frequent power-off of the HDD.
(3) The reason for preventing frequent switching on / off of the HDD power is that there is a lifetime of the HDD coming from turning on / off of the HDD power.

The life mode of the HDD in the embodiment will be described.
(1) Bearing life: Determined by rotational speed and total rotational speed. The shorter the HDD ON time, the longer the lifetime.
(2) Life of the support structure portion of the machine: It is considered that the longer the HDD is turned on and off, the shorter the life. This is not a problem with recent HDDs.
(3) Capacitor life: depends on temperature and energization time. It is said that the lifetime is halved when the temperature of 10 ° C is high. This will increase the life if the power is turned off.
(4) Life of power supply circuit: This is considered to be a randomly occurring failure.
Currently, (1) and (3) determine the lifetime of the HDD, and the effect of turning off the HDD power is expected.

The HDD backup in the embodiment will be described.
(1) Both HDD1 and HDD2 have the same data. However, the system data and history data have A and B in the HDD 2 and are copied from the HDD 1 to the system data A and history A every day, and to the system data B and history B on the next day.
(2) The system data and the history data are not distinguished from each other, and can be simply increased or changed during operation.
(3) The system data is data for operating the monitoring system. The telephone number of the communication terminal, the interpretation method of the digital data of the communication terminal, the interpretation method of the analog data, and the energization time of the HDD 1 are from 8:30 in the morning. Whether the communication terminal is from 1st unit to 10th unit, whether it is by 18:00 or 19:00, it means data that has increased from 1st unit to 12th unit. System data is not changed daily, but sometimes when adjusting the operation of the surveillance system. For this reason, it is preferable that the system data is also backed up every day and remains in the HDD 2 as backup data whenever the system data is changed.
(4) History data refers to daily reports, monthly reports, annual reports, trend data, alarm history, and operation history.
The storage device of the monitoring device is made to operate only when it is required when processing for reading or storing information is performed.
