The transmission control unit 24 converts the security start information into a command. The transmission of the command is performed by executing steps S701 to S705. As described above, the alarm transmitting device recognizes that the security operation has been set from the remote operation device K1. The command control unit 30 outputs the security start information to the alarm data editing unit 14 and stores the information in the security information storage unit 35. The alarm data editing unit 14 generates alarm data. In the alarm data, C
(Security start) is set. The communication control unit 16 transmits the alarm data to the monitoring center. Thereby, the monitoring center can recognize that the security start has been set.

Next, the alarm transmitting device notifies all the remote control devices that the start of security has been set. The method will be described below. The command control unit 30 reads the security start information stored in the security information storage unit 35 and creates a command. The transmission of the command is performed by executing steps S701 to S705.

Then, the display units of all the remote control devices indicate 6 to indicate that the security start has been set.
The button 02 is lit in red (start security). Thus, even if a security start setting is made in one of a plurality of connected remote operation devices, the security start setting can be confirmed in another remote operation device.
Security release is set in the same procedure.

Next, a process until the information is transmitted to the monitoring center when an abnormal state such as a fire or a gas leak has occurred will be described. Here, it is assumed that security start has been set. The sensor information detecting unit 11 includes a sensor S1
An abnormal state such as a gas leak or a fire is determined based on the sensor information of ~ Sn. If an abnormality has occurred, the abnormal state information is output from the sensor information detection unit 11 to the alarm data editing unit 14 via the sensor information storage unit 12.

The alarm data editing unit 14 edits alarm data based on the abnormal state information from the sensor information storage unit 12 and the time information from the clock unit 17. For example, the sensor S
Assuming that 1 detects a fire and the time is 12:00, the alarm data is A (abnormal state) in the information area, A (fire) in the state area, S1 in the equipment area, and 12:00 in the time area.
The configuration is such that data corresponding to 0 is stored.

The alarm data is transmitted to the monitoring center via the communication control unit 16. Thereby, the monitoring center can recognize that the fire has occurred in the sensor S1. Further, the alarm data editing unit 14 causes the alarm history storage unit 15 to store alarm data as an alarm history.

Next, a description will be given of a process from when an alarm history request is issued from the remote operation device to the alarm transmission device until the alarm history is displayed on the display unit of the remote operation device. For example, it is assumed that a report history request has been issued from the remote control device K1. The report history button 604 is pressed. At this time, the input unit 25 can recognize that the report history request has been made, and outputs the information to the transmission control unit 24. The transmission control unit 24 creates a command. The command is A for the address area (only receiving the alarm transmitting device), B for the source area (remote control device), K1 for the peripheral device area, and D for the header area.
(Data), and the subheader area has a configuration of 6 (report history request). The command is transmitted to the alarm transmitting device. The command transfer is performed in steps S701 to S705.

The command is B in the address area (received only from the remote control device), A in the source area (alarm transmitter), K1 in the peripheral device area, D (data) in the header area, 2 (report history) in the subheader, and data The alarm history is transmitted from the alarm transmission device to the remote operation device K1. Command transmission is performed in step S701.
Through the execution of step S705.

According to the above procedure, the remote operation device can acquire the alarm history. Then, in the remote control device, the display unit 22 can display the contents of the alert history on the monitor 601. Thus, the alarm history can be confirmed in the remote operation device.

Next, a process when a sensor information request is transmitted from the remote control device to the alarm transmitting device will be described. At this time, it is assumed that the sensor information request has been issued from the remote control device K1. Sensor information acquisition button 603
Is pressed. The input unit 25 determines that there is a sensor information request, and outputs the information to the transmission control unit 24. The transmission / reception control unit 24 creates a command. The command is
The address area is A (reception of only the alarm transmission device), the transmission source area is B (remote operation device), the peripheral device area is K1, the header area is D (data), and the subheader area is 5 (sensor information request). You. The command is transmitted to the alarm transmitting device. The command is transmitted by executing steps S701 to S705.

According to the above procedure, the alarm transmitting device can recognize that the sensor status request has been received from the remote control device K1. Then, the alarm transmitting device transmits the sensor status information to the remote control device K1. Hereinafter, the method will be described.

The command control section 30 reads out the sensor information stored in the sensor state storage section 12 and converts the information into a command. The command is sent to the remote control device. The command has a configuration in which the address area is B (only the remote control device is received), the source area is A (alarm transmitter), the device area is K1, the subheader is 1 (sensor information), and the sensor state is stored in the data. Is done. The command is transmitted by executing steps S701 to S705.

With the above procedure, the remote operation device can acquire the sensor information. In the remote control device,
The display unit 22 recognizes the content of the command and causes the monitor 601 to display sensor information. The display on the monitor 601 is
For example, the message is displayed as "December 12, 1999 19:23 Fire Occurrence". Thereby, the remote control device can acquire the sensor information from the alarm transmitting device.

Next, a description will be given of a process until a call can be made from the remote control device to the monitoring center. At this time,
It is assumed that the call request has been made from the remote control device K1.
The call button 605 is pressed. The input unit 25 recognizes that there is a call request, and outputs the information to the transmission control unit 24. The transmission control unit 24 creates a command.
The command is transmitted to the alarm transmitting device. The command is
The address area is A (receives only the alarm transmitter), the source area is B (remote control device), the peripheral device area is K1, the header area is D (data), the subheader area is 7 (call request), and the data area is monitored. The telephone number of the center is stored. Command transmission is performed in step S7.
01 to S705. The transmission control unit 24
Drives the relay L1.

According to the above procedure, the alarm transmitting device can recognize that a call request has been made from the remote control device K1.
The remote operation control unit 13 acquires the telephone number of the monitoring center from the data area of the command, and gives the telephone number to the communication control unit 16 via the signal line 101. Communication control unit 16
When the telephone number is received from the remote operation control unit 13, it can recognize that a call request has occurred, and makes a call connection to the monitoring center based on the telephone number.

Further, upon recognizing the occurrence of the call request, the call control unit 34 drives the relay RL to connect to the call unit 27 of the remote control device via the communication line 100. As a result, the communication unit 27 of the remote control device and the monitoring center are connected to each other, and a telephone call can be made from the receiver 606 to the monitoring center.

The alarm transmitting device determines whether or not a plurality of remote control devices K1 to Kn are faulty, and if a fault occurs, transmits the device number of the faulty remote control device and information on the fault to the monitoring center. I do. Hereinafter, the method will be described.

The remote operation control unit 13 has a predetermined time interval T
In step 1, ENQ data is transmitted to all connected remote control devices to confirm that all remote control devices are operating normally. The ENQ data is B (receives only the remote controller) in the address area, A (alarm transmitter) in the source area, K (all remote controllers) in the peripheral device area, and Q (ENQ in the header area). ) Is set.

The ENQ data is transmitted to all the remote control devices via the transmission / reception control unit 31 and the command transmission unit 32 (see FIG. 9). As a response signal, all the remote control devices return ACK data to the alarm transmitting device. The configuration of the ACK data is, for example, when the remote device is K1, the address region is A (reception of only the alarm transmitting device), the transmission source region is B (remote control device), the peripheral device region is K1, the header region. Is set to A (ACK).

Thus, the remote control unit 13 can confirm the responses from all the remote control devices.
The remote operation control unit 13 repeatedly transmits ENQ data to the remote operation device and receives ACK data from the remote operation device at regular time intervals. When there is no response to the ACK data from the remote operation device, the remote operation control unit 13 continuously transmits the pilot data to the remote operation device three times.

For example, if the device number of the remote control device that has not returned an ACK is K1, the pilot data is B (remote control device) in the address area and A (alarm transmission device) in the source type area. ), K in the peripheral device number area
1, D (data) is set in the header, and 8 (pilot) is set in the subheader. The remote control unit 13 transmits the pilot data to the remote control device K1 three consecutive times,
Wait for an ACK from the remote control device K1.

Here, if there is no ACK response from the remote control device K3 three times in a row, the remote control device controller 13 determines that the remote control device K1 has failed, and indicates that the remote control device K1 has failed. Is output to the alarm data editing unit 14.
The alarm data editing unit 14 edits alarm data. For example, if the remote control device K1 is out of order,
The information area is E (remote control device failure), the equipment area is K1,
The time when the failure was detected is stored in the time domain. The alarm data is transmitted to the monitoring center via the communication control unit 16 and stored in the alarm history storage unit 15. Thereby, the monitoring center can recognize that the remote control device K1 has failed.

Next, the operation from the occurrence of a maintenance and inspection request to the transmission of the information to the monitoring center will be described.

The alarm data editing unit 14 generates alarm data when a maintenance inspection request is issued from the maintenance inspection date generation unit 19. In the alarm data, D (maintenance check) is set in the information area. The alarm data is transmitted to the communication control unit 1
6 to the monitoring center. Thereby, the monitoring center can recognize that the maintenance inspection request has occurred. Further, the alarm data editing unit 14 causes the alarm history storage unit 15 to store alarm data as an alarm history.

When the monitoring center recognizes that a maintenance inspection request has been made, the monitoring center transmits the maintenance inspection information to the alarm transmitting device. The maintenance and inspection information is maintenance information (inspection items for inspection and the like) of devices (sensors, remote control devices and the like) in the alarm transmission system. Then, the maintenance and inspection information is transmitted to the remote operation control unit 13 via the communication control unit 16, and further transmitted to the command control unit 30 inside the remote operation control unit 13.

The command control unit 30 creates a command. At this time, when the maintenance and inspection information is “sensor detection test”, the command is B in the address area (receiving only the remote control device), A in the source area (alarm transmitting apparatus), and the command in the peripheral area. K (all remote control devices),
D (data) in the header area, 11 in the subheader area
(Maintenance inspection), maintenance inspection information (“sensor detection test”) is set in the data area. The command is transmitted to the remote control devices K1 to Kn. The transmission of the command is performed by executing steps S701 to S705.

As described above, the remote control devices K1 to Kn are:
Maintenance inspection information can be received. Then, the display unit inside the remote operation device displays the maintenance and inspection information on the monitor 602. In this case, a “sensor detection test” is displayed on the monitor 602. Thus, the maintenance and inspection staff and the user can perform the maintenance and inspection according to the maintenance and inspection information displayed on the monitor.

0 recognizes that a fire has occurred in the sensor unit SU1 based on the content of the command, and causes the sensor information storage unit 12 to store the information. When a sensor status information request is issued from the remote control device, the command control unit 30
Acquires the abnormality information stored in the sensor information storage unit 12.

The command control unit 30 recognizes the contents of the command and notifies the alarm data editing unit 14 that a fire has occurred in the sensor unit SU1. The alarm data editing unit 14 further generates alarm data based on the time information from the clock unit 17 and the abnormal data from the sensor unit SU1 stored in the sensor information storage unit. For the alarm data, the information area is A (abnormal state) and the state area is A
(Fire), the equipment area is SU1 (sensor unit SU
1) In the time domain, data corresponding to 12:00 is stored.

The communication control section 16 transmits the alarm data to the monitoring center. Thus, the monitoring center can recognize that a fire has occurred in the sensor unit SU1. Further, the alarm data editing unit 14 stores the alarm data in the alarm history storage unit 15 as the alarm history.
