  FIG. 2 shows a block diagram of the monitoring device, the relay device, and the monitoring terminal. As shown in FIG. 2A, the monitoring device 102 communicates with the relay devices 402,... Via the communication control unit 111, the media converter 103, and the communication cable 300. It also communicates with the monitoring client 100 via the LAN.

  As shown in FIG. 2B, the relay device 402 is connected to the wireless device 403 by communication control (part 1), and is connected to the communication cable 300 via the wireless control unit 411 and the media converter 401 (part 2) cable.

This monitoring system has three basic functions.
1. Current value display function: Displays real-time data of the monitoring target equipment 504 on the screen of the monitoring device 102.
2. Alarm display function: When an alarm is generated in the monitored facility 504, the alarm status of the facility is displayed on the monitoring device 102 to notify the administrator.
3. Operation recording function: Records the operation state of the monitoring target facility 504. For this purpose, the monitoring device 102 collects and stores operation records (daily reports, etc.) stored in the monitoring terminals 502,.
These functions are obtained by communication between the monitoring device 102 and the monitoring terminals 502,.

The three types of functions of the monitoring system are realized as follows.
1. The current value display function displays the current value data in the monitoring terminal on the screen of the monitoring device. Current value data includes digital data and analog data. The digital data includes operation of individual devices in the monitored equipment, failure signal on / off signals. Analog data includes water level and pump current. These data are acquired online from the monitoring terminal by the monitoring device and displayed on the monitoring device.
2. The alarm display function is a function for displaying the alarm content on the monitoring device screen when the monitoring device obtains the data set as the alarm signal in the digital data among the current value data in the monitoring terminal online from the monitoring terminal. .
3. With the operation record function, the operation record to be monitored (history of the time when the signal was turned on and off, trend data for the time of the analog signal, etc.) is saved in the monitoring terminal, and usually once a day, The monitoring device visits the monitoring terminal and collects the data. Since the amount of data is large and the number of monitoring terminals is large, it takes a long time to complete operation record acquisition.

  Here, if an alarm is generated in the monitored equipment while the monitoring device circulates the monitoring terminal once a day and collects operation record data, the alarm is promptly displayed on the monitoring device side. The following operations are performed.

  FIG. 3 shows an example of data when wireless communication is performed. The example of FIG. 3A shows wireless data transmitted from the monitoring terminals 518, 514, 510 shown in FIG. In wireless communication, since the data of the monitoring terminal 510 arrives via the monitoring terminals 514 and 518, the data received by the relay device 405 is the data of the monitoring terminals 518, 514 and 510 as shown in FIG. Are connected in series and transmitted. The data of each monitoring terminal includes “wireless device usage data”, “alarm status data”, and “daily report data”. Here, “wireless device usage data” is data added for wireless communication by the wireless device, and “daily report data” is data transmitted at the time of daily report acquisition once a day. Since “daily report data” has a large capacity, it is not transmitted in a single communication, but is transmitted in several blocks in blocks.

  The alarm status data changes as shown in FIG. Even if the alarm is generated or the alarm is recovered, the alarm state data takes the value “previous value + 1” when the alarm state changes. This data is created by the monitoring terminal, and the relay device detects the change and detects that the alarm state has changed.

  FIG. 5 shows an example of a flowchart of the program of the relay device. While acquiring the daily report data, the relay device checks whether there is a change in the alarm status data from the monitoring terminal (step 701), and if there is a change, requests the current value data from the monitoring terminal ( Step 702), the current value data is received (Step 703). Then, the daily report data reception is continued (the next daily report data is received) (step 704), and it is determined whether or not the process ends (step 705), and the process returns to step 701 or ends. Since the current value data includes real-time data to be monitored including alarm data, the alarm occurrence status can be known. An example of data when the relay device requests the current value data and the monitoring terminal 518 transmits the current value is shown in FIG.

  FIG. 6 shows an example of a flowchart of the program on the monitoring terminal side. If there is no change in status such as alarm occurrence or recovery in the monitoring target while the daily report data is being transmitted, the daily report data is continuously transmitted (step 710). If there is a change in state such as the occurrence or recovery of an alarm, the value of the alarm state data is incremented by 1 (step 711) to notify the relay device that the alarm has changed. If there is no request for the current value data, the daily data transmission is continued (the next daily data block is transmitted) (step 714), and the process returns to step 712. If there is a request for the current value data from the relay device, transmission of the daily report data is temporarily stopped and the current value data is transmitted (steps 712 and 713), and the daily report data transmission is continued (the next daily report data block is transmitted) (step 715). ), The process returns to step 710 or ends.

  As described in the above embodiment, even if an alarm occurs during communication of daily report data that takes a long communication time in wireless communication, the alarm data can be acquired immediately and the alarm content can be displayed on the monitoring device. it can. As a result, it is possible to quickly respond to an alarm generated in the monitoring target. Thereby, the responsiveness of the monitoring system can be improved while using radio.

  A second embodiment will be described. Compared with the system of the first embodiment, the monitoring system of the present embodiment interrupts the daily report acquisition when the operator of the monitoring apparatus tries to view the current value of the monitored equipment during the daily report acquisition. It is different in that it also has a function of acquiring a value and returning to daily report acquisition after the operation of displaying the current value is completed. The system configuration of the present embodiment can be the same as that of the first embodiment shown in FIG.

  The monitoring device 102 has means for instructing the relay devices 402,... To receive the current value data of the monitored equipment from the monitoring terminals 502,. Even when an operator of the apparatus 102 performs a control operation, the control operation can be started by interrupting the acquisition of the daily report. This means can be realized by computer software.

  The relay device 402, ... detects or monitors a change in data indicating an alarm state mixed in daily data received from the monitoring terminal 502, ..., and a change in data indicating the alarm state. .. Which receives an instruction from the device 102 and instructs the monitoring terminals 502,...

  An example of the operation of the relay device according to the second embodiment will be described. Acquisition of the current value during daily report acquisition will be described. FIG. 7 shows an example of a flowchart. While acquiring the daily report data, the relay device checks whether there is a current value acquisition operation by the operator (step 720), and if there is an operation, requests the current value data from the monitoring terminal (step 720). 721), current value data is received (step 722). Then, the daily report data reception is continued (the next daily report data is received) (step 723), and it is determined whether or not the process ends (step 724), and the process returns to step 720 or ends. In this way, the relay device can perform an operation of acquiring the current value during daily report acquisition.

  Next, a control operation during daily report acquisition will be described. FIG. 8 shows an example of a flowchart. While acquiring the daily report data, the relay device checks whether there is an operator's current value control operation (step 730), and if there is an operation, transmits the control data to the monitoring terminal (step 731). ), The control result is received (step 732). Then, the daily report data reception is continued (the next daily report data is received) (step 733), and it is determined whether or not the process ends (step 734), and the process returns to step 730 or ends. In this way, the relay device can perform a control operation during acquisition of the daily report.
