With this configuration, normally, each repeater RP
Collects status information from various connected terminal devices (monitoring terminal devices such as fire detectors and controlled terminal devices such as fire doors), and makes various judgments based on the collected status information. When the polling signal from the fire receiver RE is received, the judgment result information and the collected status information are sent to the fire receiver RE. Fire receiver RE
Upon receiving the judgment result information and the status information from the repeater, performs appropriate management based on the information contents. For example, when a fire signal indicating the occurrence of a fire is received, a fire operation that issues an alarm such as a bell ringing is performed, a fire recovery operation is performed when the fire subsides, and when necessary. , Sending information to other places, so-called transfer.

As the operation of each relay RP, the interlocking operation of the controlled terminal equipment is also performed. That is, when it is determined that a fire has occurred, that is, that the fire detector has operated based on the information from the connected fire detector, the relay device causes the relay device to cover the fire door or the like related to the fire detector. Sends an operation command to the control terminal device. If the controlled terminal device to which the operation command is to be sent is connected to another repeater, the controlled terminal device is designated to the other repeater and the operation command is sent. Which controlled terminal device is to be operated when each monitoring terminal device such as each fire detector operates is stored in the storage area ROM 23 in the form of a table of each monitored terminal device to the controlled terminal device to be operated. It is stored as a division interlocking table.

The partition interlocking table stored in the storage area ROM 23 will be described with reference to FIGS. 3 and 4. In the present invention, instead of operating all the controlled terminal devices at once when the monitoring terminal device operates due to detection of a fire or the like, the analog type sensor does not operate as a fire alarm as shown in FIG. In addition to the operation level as a level, the first preliminary alarm (pre-alarm) level with low fire probability and the second preliminary alarm (second pre-alarm) with higher fire probability than the first preliminary alarm, that is, closer to the fire operation level Since there is a level, even if the first preliminary alarm (first pre-alarm) level or the second preliminary alarm (second pre-alarm) level is detected, it is preferable to operate at that time I am trying to let you.

Referring to FIG. 3 showing an example of the operation level of the analog type sensor, the pre-alarm level and the fire alarm level (fire operation level) in each of the 1, 2, and 3 types of sensors are shown in FIG. 01, 02, 0 shown to the right of
It can be roughly classified into four detection levels of 3, 04. For example, one type of fire alarm level (fire), two types of pre-alarm levels (pre-alarm), two types of multi-stage second pre-alarm levels (second pre-alarm), and three types of multi-stage first The detection level is 02, which is almost the same as the preliminary warning level (first pre-alarm). Regarding the types of 1 to 3 types, in the case of a smoke detector, for example, 2 types (normal fire discrimination level) have a smoke density of about 10% / m, and 3 types (of the smoke control equipment The level is about 15% / m and the level for type 1 is about 5% / m. In the case of a heat sensor,
For example, one type is about 60 ° C, two types are about 65 ° C, and three types are about 75 ° C.
℃. Each level can be set within a predetermined range for each sensor, and the level is raised or lowered depending on the installation environment to perform accurate interlocking.

In consideration of the above, as the division interlocking table stored in the storage area ROM 23, the detection level of each sensor in FIG. 3 is set as the interlocking level as shown in FIG. That is, for each interlocking level,
Set the controlled terminal device to be linked. In this case, when the higher interlocking level is detected, the controlled terminal device set to the lower interlocking level is also operated. For example, when the smoke sensor at address 01 (two-step multi-step) detects the second preliminary alarm level, the detection level, that is, the interlocking level is 02 from FIG. 3, so the interlocked address 43 is read out and the address 43 is read. The emergency elevator is called. When the fire progresses and the fire alarm level is detected, the detection level, that is, the interlocking level is 03 from FIG. 3, so the address 43 of the lower interlocking level 02 and the addresses 63, 41, 44 of the interlocking level 03.
Is read out, the damper at address 63 is activated, the emergency broadcast at address 41 is started, and the address 44 is transferred to the central monitoring board. When the fire further progresses and three levels are detected, the interlocking level is 04 from FIG. 3, so the address 62 is further read in addition to the above, and the fire door at the address 62 is activated. In this way, in the division interlocking table, the controlled terminal devices are not operated at the same time when the detectors fire, but the detected values of the detectors are stepwise as they reach each detection level, that is, the interlocking level. Each controlled terminal device is operated.

The operation of the fire alarm equipment shown in FIGS. 1 and 2 will be described below with reference to the flowchart of FIG. 5 showing the operation of the fire receiver RE and the flowcharts of FIGS. 6 and 7 showing the operation of the repeater RP. Will be explained.

The n-th repeater RP polls each terminal and reads the status information while there is no call from the fire receiver RE (N in step 208) (step 210). Then, when the level detected by the sensor exceeds a predetermined fire determination level (there are a plurality of fire determination levels) (Y in step 214), the storage area ROM is stored in accordance with the interlocking level.
From the division interlocking table of 23, all controlled terminal devices below the interlocking level are read (step 220),
An operation signal is sent to the controlled terminal device (step 22).
6) The state of the sensor is stored in the storage area RAM 22 (step 216). When the terminal to be interlocked is out of the monitoring range of the n-th repeater (Y in step 222), the interlocking signal is sent to another repeater (step 224). As described above, the controlled terminal devices to be interlocked are set by being classified according to the level detected by the sensor, and can perform appropriate operations such as smoke prevention and smoke emission depending on the fire condition. If there is an information return command by polling from the fire receiver RE (step 2
08 Y and step 238 Y), storage area RAM
The contents stored in 22 are read and the fire receiver R
Return to E.

The fire receiver RE constantly collects status information from N relays by polling (step 1).
10). Then, when the fact that there is a fire is read from the repeater (Y in step 112), the necessary fire operation is performed (step 116).

In the present embodiment, when a supervisor such as a disaster prevention center equipped with a fire receiver RE finds it necessary, he / she designates the detector and the operation level by using the ten keys of the operation section OP. Then, the division control input can be performed. If there is a classification control input (Y in step 108, Y in step 120, and step 124), the fire receiver RE causes the relay device to perform the same processing as when the designated sensor operates even if it does not. To make it happen
A classification control command is sent to the repeater (step 12)
6).

Upon receiving the sorting control command (Y in step 208, Y in step 228), the relay terminal RP reads out the controlled terminal equipment of the designated level to be linked with the designated terminal from the storage area ROM 23 (step 23
0), an operation command is sent to the controlled terminal device (step 236). If it is outside the range of the repeater, that is, if it is a controlled terminal device connected to a repeater other than the repeater (Y in step 232), an interlocking command is sent to the corresponding repeater (step 234), and the interlocking operation is performed. The repeater receiving the command (Y in step 242) issues an operation command to the corresponding controlled terminal device (step 244).

By making it possible to perform the division control input in this way, for example, a fire may be caused to each of the detectors on the same floor of the operated detectors even if the detectors are not yet activated. As in the case of detection, the related controlled terminal device can be operated in an interlocking manner, and proactive protection measures can be taken depending on the situation.

[0023]

As described above, according to the present invention, a plurality of terminal devices including the controlled terminal device and the monitoring terminal device are connected to the receiving portion of the repeater or the fire receiver, and the receiving portion includes each monitoring terminal. In a fire alarm facility that links related controlled terminal devices when the device is operating, the operation level of the monitoring terminal device is set in multiple stages, and the operation level of each monitoring terminal device is linked at each stage. Since the controlled terminal device to be controlled is set in the division interlocking table, there is an effect that an effective controlled terminal device suitable for the progress of a fire can be operated. In addition to the above, it is possible to artificially specify one of the monitoring terminal device and the operation level of the monitoring terminal device. When such a specification is made, the specified monitoring is performed. Since the controlled terminal device according to the operation level of the operating terminal device is read from the contents of the division interlocking table and operated, the controlled terminal device can be operated in advance in case of fire occurrence as needed. There is also the effect that humans can intervene.
