[Effect]

In the building management system equipped with the fire/power outage processing function of the present invention, when a fire/power outage etc. occurs, an alarm signal is sent from the alarm means of the terminal to the host computer. This alarm signal activates the host computer's fire/power outage handling means,
By referring to the table, devices corresponding to the point where a fire/power outage, etc. occurred are extracted, and an emergency stop command is issued for each device. As a result, the equipment control means of the terminal performs emergency stop control of the equipment. At this time, the contents of the monitoring buffer of the terminal are stored according to the state immediately before the control.

After that, when the operator keys in the fire/power outage batch recovery command and the host computer's recovery processing means sends the batch recovery command to the terminal, the device control means of the terminal refers to the monitoring buffer and performs the fire/power outage recovery command. The state of each device is controlled to the state immediately before the occurrence of the event. In this way, the operator does not need to specify the details when performing an emergency stop or recovery.
All you have to do is key in the recovery command. i.e. emergency stop;
Since the contents of restoration are determined by the contents registered in the table and the contents stored in the monitoring buffer, there is no need for judgment or burden on the operator.

Reference numeral 2 indicates a monitoring buffer, and reference numeral 43 indicates an alarm notification section. In the system shown in FIG. 2, when a pipe hole condition occurs and the detector is activated, this is recognized by the terminal 4 and an alarm signal is sent from the alarm notification section 43 to the host computer 3. On the other hand, the alarm processing unit 36 receives the alarm signal sent from the terminal 4, and starts the fire/power outage processing program 35 if the alarm signal is a fire/power outage alarm. table 3
4, as shown in Figure 4, registers emergency stop and other processing (e.g. opening and closing of doors) and target equipment, etc., corresponding to the location where the fire/power outage occurred, for example, the number of the detector that detected the fire/power outage. This is what I did. The flag 33 is turned on when a fire/power outage occurs, and turned off when a recovery command is issued, and is referenced, for example, when executing a normal control program. If the flag 33 is on, the fire/

The power outage processing program 35 refers to the table 34 and extracts equipment corresponding to the location where the fire/power outage occurred based on the alarm signal, for example, the number of the detector that detected the occurrence of the fire/power outage. Then, as shown in FIG. 5, the device name and emergency stop command are edited and sent to the terminal 4, and the flag 33 is turned on. At the same time, a warning is output to the operator. FIG. 3 shows the flow of processing by the fire/power outage processing program 35 as described above. The key input decoding unit 3 decodes the function input from the keyboard 6, and when the key input is a fire/power outage recovery function, the recovery processing unit 32 operates. When there is a key input for fire/power outage recovery, the recovery processing unit 32 turns off the fire/power outage flag of the flag 33 and issues a fire/power outage batch recovery command to the terminal 4 . In the terminal 4, the monitoring buffer 42 stores the status of each device in correspondence with the device as shown in FIG.
Normally, when a control command is issued by a control program or an operator, the equipment control unit 41 controls the equipment according to the command, and also monitors the state of the equipment.
However, if the fire/power outage processing program 35 issues an emergency stop command in the form shown in FIG. Emergency stop control is performed in response to commands without being rewritten. Therefore, the contents of the monitoring buffer 42 are stored as they were just before the fire/power outage occurred, and each device is stopped in an emergency.

Then, when the recovery processing unit 32 issues a fire/power outage batch recovery command, the device control unit 41 controls the monitoring buffer 42
Control each device by referring to the contents of , and restore it to the state immediately before the fire/power outage occurred. In addition, although one terminal was explained in FIG. 2, other terminals in the system shown in FIG. It goes without saying that the terminal that has the equipment under control may be different from the terminal that has the equipment under control, and it goes without saying that there may be a plurality of terminals that have equipment under the control that will be controlled when the fire/power outage occurs.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, devices to be stopped in an emergency according to the location where a fire/power outage occurs are registered in a table, and when a fire/power outage occurs, devices are automatically stopped according to the registered contents of the table. Since an emergency stop command is issued at the same time, the equipment can be controlled quickly and accurately.

In addition, even at the time of recovery, the device status immediately before the fire/power outage occurred is left in the terminal's monitoring buffer, and the configuration is configured so that the recovery process is performed simply by issuing a recovery command, greatly reducing the burden on the operator. At the same time, the operator must
Since it is only necessary to issue a command to restore power outage, it is possible to eliminate operator errors.
