Problem to be Solved by the Invention Since the conventional building management system is configured as described above, the monitoring buffer 1
8 is held on the terminal side, and the content is used to return the equipment to its previous state at the time of recovery. However, in the event of a power outage, the signal is sent from the terminal 5 to the central processing unit 4, and the fire/power outage program is After startup, an emergency stop command is sent to the terminal 5, and the contents of the monitoring buffer 18 are fixed for the first time at that point, but in the meantime, the power to the equipment has already been turned off and all of them are in the OFF state. However, with the block connection described above, there was a problem that the monitoring buffer 18 could not be fixed upon reception of this emergency stop.

[0006] This invention was made in order to solve the above-mentioned problems, and it is possible to maintain the immediately previous state of equipment and equipment when a power outage occurs, and depending on the equipment, to return to the previous state. The purpose is to obtain a building management system that can not only meet the schedule at the time of restoration, but also the schedule at the time of restoration.

[0007]

[Means for Solving the Problems] A building management system according to the present invention receives a restoration command based on power outage information after a power outage is restored, refers to an all-equipment monitoring buffer, and monitors equipment of the equipment that is in an on state. A recovery processing unit is provided that sends an on-control command to the terminal processing device along with a power outage recovery command, and the device control unit receives the power outage recovery command and refers to a schedule table in which schedules for each device are registered, and performs the above operations. The device is configured to perform control based on a schedule, or when the schedule is not registered, the device is configured to perform control immediately before a power outage occurs.

[0008]

[Operation] The central processing unit in this invention directly inputs the power outage signal to the alarm processing unit and performs alarm processing, so that the power outage program is activated faster than before, and all equipment owned by the central processing unit is activated. The status can be instantly held in the monitoring buffer, and the terminal processing device side can perform automatic control by referring to the entire equipment monitoring buffer when returning the equipment to the state immediately before the power outage occurred when the power is restored. In addition, when matching the schedule status, the central processing unit outputs a command to the terminal processing unit to return to scheduled operation, and the terminal processing unit searches for devices whose schedule table is on and turns them on. Let control take place.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a display device, 2 is a printer device, 3 is a keyboard for inputting recovery commands, 4 is a central processing unit that performs various data processing, 5 is a terminal processing device,
6 is a group of equipment connected to the terminal processing device 5; 7 is an alarm output unit that processes alarm display and alarm printing for the display device 1 and printer device 2; and 8 is a fire/power outage program that directly receives power outage signals. an alarm processing unit that activates
9 is the fire/power outage processing program, 10 is a flag for recognizing power outages, etc., 11 is a table in which devices are registered for each location, 12 is a key input section, 13 is a recovery processing section, 14
15 is an alarm notification section, 16 is a schedule table storing schedules for each device, and 17 is a device control section.

Next, the operation will be explained. First, when a power outage condition occurs, the alarm processing section 8 detects it. As a result, the fire/power outage processing program 9 is activated, stores the current monitoring status of all equipment in the monitoring buffer 14, and sets a power outage state recognition flag in the flag 10. Furthermore, with reference to the table 11, necessary automatic control is performed when a power outage occurs, and the alarm output unit 7 automatically displays a related power reception/transformation screen on the display device 1. Additionally, a message indicating the occurrence of a power outage is printed on the printer device 2.

On the other hand, after the power outage is restored and the power source is switched from the private power generation to the commercial side, a restoration command is issued from the keyboard 3 in order to carry out power outage restoration processing for the facility equipment group 6. This restoration command is decoded by the key input section 12, the command is transmitted to the restoration processing section 13, and the power outage state recognition flag of the flag 10 is reset. Further, by referring to the all-equipment monitoring buffer 14, a device in an on state is searched for, and a command to turn on the corresponding device is sent to the terminal processing device 5 along with a command to restore the power outage. Therefore, when the device control unit 17 receives the control signal of the power failure recovery command, it searches the previously registered schedule table 16, and if there is a schedule for the corresponding device,
Control is performed to match the schedule state at that time, and if the schedule of the corresponding device is not registered, on control is performed to return to the state immediately before the power outage occurred.
