Problems to be Solved by the Invention In the conventional configuration, when interlocking the air conditioning equipment management system and the security pipe tapping system, such as when stopping the air conditioning when the door is locked or starting the air conditioning when the door is unlocked, This was handled by exchanging data between the central units, but if the frequency of interlocking becomes high or the amount of data increases, the burden on the central unit increases and the monitoring and control function of the central unit becomes impaired. There was a point. Therefore, there was a problem in that the interlocking between the crime prevention management system and the air conditioning management system had to be kept to a minimum, making it impossible to create a more efficient concave circle.

The present invention solves the above-mentioned conventional problems, and provides an efficient and easy-to-use device that more closely links air conditioning monitoring control and crime prevention monitoring control without placing a burden on the central device. The purpose is to

Means for Solving the Problem In order to solve this problem, the building management device of the present invention has the following features:
A central device that performs comprehensive management and control from a remote location, an air conditioning control means that operates/stops multiple air conditioners installed at each location in the building, and controls according to the air conditioning load, and a lock that locks when a room user enters or leaves the room. - At the same time as unlocking, inputting the detection signal of the human detection sensor, communicates with the crime prevention management means that monitors for intruders, the air conditioning control means, and the crime prevention management means with each other, It has at least one monitoring control device composed of three means of communication control means that transmits and receives data to and from the central device, and at least one equipment control device that monitors and controls equipment such as a plurality of lighting devices and heat source equipment.

In addition, a human detection sensor detects the presence or absence of intruders from the time of exit and performs crime prevention monitoring. The air conditioning control means and crime prevention management means are mutually exclusive (
(Communicates and works to stop the air conditioner when locked/ζ and operate and control the air conditioner when unlocked. The central device is connected to the supervisory control device and equipment control device by a data transmission line. Therefore, when a room is locked as described above and the air conditioner corresponding to that room is stopped, a signal is sent to the supervisory control device, central device, and equipment control device in that order, and the locked room is The lighting equipment will be turned off, and multiple heat source devices will be controlled to partially stop operation according to the air conditioning load status.Therefore, optimal linked control will be realized.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3. In FIG. 1, a supervisory control device 1 is connected to a central device 9 that remotely performs integrated supervisory control via a data transmission line 8, and the supervisory control device 1 is installed at each location within the building. an air conditioning control means 1a that operates and stops a plurality of air conditioners 4 and performs control according to the air conditioning load; processes locking and unlocking signals according to users entering and leaving the room; and monitors intruders after leaving the office. and a communication control means 1C that is interconnected with the air conditioning control means 1a and the crime prevention management means 1b and capable of data communication, and that transmits and receives data to and from the central device 9 via the data transmission line 8. It is configured. Further, the air conditioning control means 1a is connected to receive signals from an infrared sensor 2 for counting the number of people in the room related to the air conditioning load when entering and leaving the room, and a temperature and humidity sensor 3 for detecting the temperature and humidity in the room. Fan 4a, hot and cold water valve 4b, and humidifier 4 included in the main body of the machine 4
C and 1 are connected to the damper 4d so that a control signal is output in accordance with the air conditioning load.

Still, the crime prevention management means 1b includes an infrared sensor 2 which is used as a human detection sensor to monitor intruders after leaving the office (shared with the infrared sensor 2 which counts the number of people in the room when entering and leaving the room), and a magnetic sensor. A card reader 5 for reading the data on the card 6a, determining whether the data matches the data, and outputting a matching signal, and a key person crab unit 6 for enabling key manual operation when the matching signal is input. It is connected to receive the signal emitted by the controller and output a control signal. Accordingly, a control signal is outputted to the electronic lock 7 attached to a door for entering/exiting the room based on the key human input signal. The electronic lock 7 has a function of being locked or unlocked depending on the type of control signal input to the key.

Next, connected to the facility control device 10a are lighting fixtures 11a, 11b, and 11c that are controlled to blink and blink, and an exhaust fan 12 that performs two-rotation speed control for operation and stop.

Unfortunately, the equipment control device 1ob is the heat source device 1 that produces cold and hot water.
4a, 14b, 14c and the circulation pump 15 that transports cold and hot water are controlled to operate, stop, etc.

The various control devices described above, that is, the central device 9, the supervisory control device 1, and the equipment control devices 10a and 10b, are constructed of electronic circuits using microcomputers.

Next, with reference to the system diagram in FIG.
The control execution operation will be explained using the operation flowcharts shown in FIGS. 2 and 3. In FIG. 2, at step 100, the user who is currently operating and monitoring the equipment inserts the magnetic card 5a containing specific data into the card reader 5 and verifies it when leaving the room. If it matches the card data collated in step 101 (YES), a matching signal is sent to the crime prevention management means 1b. In step 102, the crime prevention management means 1b allows transmission from the key person crab unit 6 based on the signal. In step 103, the user operates the key person crab knit 6 and inputs locking request data using the keys. In step 104, the crime prevention management means 1b receives the locking request data, outputs a locking command signal, locks the electronic lock 7, and in step 105 outputs a control stop signal to the air conditioning control means 1a, and then outputs a control stop signal to the air conditioning control means 1a. Then, the air conditioner 4 (fan 4a, cold/hot water pulp 4b, humidifier 4c, dampers 91, -14d, etc.) is stopped as shown in steps 120 to 121 in FIG.

In step 106, the infrared sensor 2 monitors whether an intruder has appeared in the room. In step 107, if there is no intruder, the process returns to step 1o6 and constant monitoring is repeated. If there is, that is, it is detected, the process proceeds to step 1o8VC, and the crime prevention management means 1b outputs an abnormality signal, which is transmitted via the communication control means 1c. An external signal outputted from the communication controller SIG in the supervisory control device 1 is sent to the central device 9 via the data transmission line 8, and the presence of an intruder is displayed on the display. The central device 9 is also notified that the air conditioner 4 has stopped and that the room is locked. In response to the above notification, the central device 9 instructs the facility control device 10a controlling the lighting in the room to turn off the light, and also notifies the facility control device 1ob to stop the air conditioner 4.

The facility control device 10b thus controls the heat source devices 14a and 14b based on the notification regarding the operating status of the air conditioners 4 throughout the building, which is issued from the central device 9.

14c number control and circulation pump 15 rotation speed 1o
・Can be controlled. .

In FIG. 2, if the data on the magnetic card 6a do not match as a result of checking in step 101, the process proceeds to step 112 and returns to the state immediately before the card reader input interruption.

Further, in step 103, when the operation of the key person crab unit 6 is data input of an unlocking request, the process proceeds to step 110, where the crime prevention management means 1b outputs an unlocking command signal and unlocks the electronic lock 7, and at the same time, in step 111 An air conditioning control start signal is output to the air conditioning control means 1a, and the air conditioner 4 (fan 4a, cold/hot water pulp 4b, humidifier 4c, damper 4d, etc. ) and start control.

In addition, when the room is locked, the air conditioner 4 can be turned on as needed.
