Abstract

PURPOSE:To economize a system by transmitting the information inherent in a building such as power collected by a remote equipment to a centralized management equipment via a private branch exchange in a building so as to eliminate the need for a private line. CONSTITUTION:Remote equipments 1a-1n are provided at every floor and the centralized management equipment 2 supervising and controlling each management item such as power is provided based on the inherent information such as power collected by the remote equipments 1a-1n. The remote equipments 1a-1n and the centralized management equipment 2 are connected to the private branch exchange (PBX) 4 in the same building via a private branch exchange network 5 and the inherent information such as power collected by the remote equipments 1a-1n is transmitted to the central management equipment 2 via the PBX 4 and the network 5. Thus, no private line to transmit the inherent information is required and the economicity of the system is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a building management system that monitors and controls various management items related to electric power, air conditioning, disaster prevention, etc. within a building.

B3 Summary of the Invention The present invention is a building management system configured to transmit building-specific information such as electric power collected by a remote device to a central management device through a private branch telephone exchange in the building. This eliminates the need for dedicated wiring between the remote device and the remote device, making the system more economical.

C0 Conventional Technology Conventionally, in this type of building management system,
As shown in Figure 4, remote devices 1 &~1 are installed on each floor.
n, and each remote device la to 1n collects building-specific information (hereinafter abbreviated as “specific information”) regarding power, air conditioning, disaster prevention, etc. on each floor from equipment and sensors connected to each remote device. The collected unique information is transmitted via a dedicated line 3 to a central control device 2 located in a basement, for example, and is configured to monitor and control various management items such as power, air conditioning, and disaster prevention.

Problems to be solved by the D0 invention However, in the conventional building management system described above, each of the remote devices i 1 a to 1n and the central management device 2
Since the private line 3 is used to connect the private line 3, there is a problem in that the cost associated with installing the private line 3 becomes enormous.

The present invention has been made to solve these problems, and an object of the present invention is to provide a building management system that does not require a dedicated line and can make the system more economical.

Means for Solving the E0 Problem The present invention is configured to transmit building-specific information centralized at a remote device to a central management device via a local telephone converter in the building.

Building-specific information such as power collected by the X.21 action remote device is transmitted to the central management device via the building's private branch telephone exchange.

G. Embodiment FIG. 1 is a block diagram showing an embodiment of the present invention, in which remote devices 1a to 1n are installed on each of five floors in the conventional configuration and P1.
1. of the power collected by these remote devices 1&~1n is provided. i! A central management device 2 is provided that monitors and controls various management items such as power based on LI availability information.However, unlike the conventional configuration, each remote device 1i
~1n and the central control device 2 exchange bad news on the private branch exchange (PBX) 4 in the same building! ! Continued through 45.

Unique information such as electric power collected by each remote device 1a to 1n is transmitted to the central management device 2 via the PBX 4 and private telephone exchange network 5.
transmitted to.

Therefore, there is no need for a dedicated roundabout for transmitting unique information, and the system can be made more economical.

Here, if the private telephone switching network 6 is used, the traffic of the switching network 6 will increase, but in this embodiment, intelligent functions are added to the remote devices 1a to 1n, and the traffic is processed on each floor. The management items to be obtained are handled individually by each remote device 1&~in, and the central pipe embedded #
2. We are trying to reduce the amount of information to be delivered and suppress the increase in traffic.

30, the NCU 23 is connected to the PBX 4 via the private telephone exchange network 5t'', and transmits information to and from the remote device [IBxln] by the switching connection operation of the PBX 4.

In this case, the transmitted information is transmitted in serial code format.

Therefore, the information sent from the central management device ft2 side is 5I.
After being converted into a serial code in O22, NCU2
3 is input. On the other hand, the information in the serial code format received by the NCU 23 from the PBX 4 is converted into a parallel significand bit code in 5r022, and stored in the memory 21 and FDM 25 under the control of the MPU 20.
It is recorded as a character in W26. It is also displayed as characters on the CRT 28.

Note that the unique information collected from the remote devices 1a to 1n is aggregated at predetermined time intervals by the MPU 20, and
The data is displayed on the CRT 28 as a daily report in graph form through the graphic processing of the DC 30. Additionally, if an abnormality is detected on any floor based on the information collected from the remote equipment Pltla~1n, this will be detected by MTW27

FIG. 3 is a block diagram showing a specific example of the remote devices 1a to 1n, including a microprocessor (MPUJIO, line control unit 11, printer 12, and
．． Digital output port (Do) 13, Digital input (DI) port 14. Equipped with an analog input port 15, information indicating the status of equipment, etc. is sent to D114, and analog information such as measured values of electric power is sent to AI 15.
is read into the MPU 10 via the . For management items that can be handled only on each floor, MPU
The necessary processing by the distributed processing of No. 10 is performed on the target equipment via D013. However, emergency information such as jurisdiction and information that should be transmitted at predetermined time intervals are transmitted to the central management device 2 via the NCU II and PBX 4.

In this case, the N'CU 23 of the central control device 2 and the NCUs 11 of the resonator devices 1a to 1n both have an automatic dialing function, and the central control unit 23 of the central control device 2 and the NCU 11 of the resonator devices 1a to 1n each have an automatic dialing function, *ivi2 and remote devices 1a to 1n can be called in the same way as an extension telephone and information can be mutually transmitted.

Therefore, information can be communicated not only between the central control device 2 and the remote devices 1a to ln, but also between the remote i devices when necessary, so that in an emergency such as a fire, the central control device By transmitting emergency information to a remote device on an adjacent floor without waiting for the second command, it is possible to control the opening and closing of fire shutters, etc.

As described in detail of the G0 invention, the present invention transmits building-specific information such as electric power concentrated by a remote device to the central management device via the private branch telephone exchange in the building. This eliminates the need for a dedicated line between the two terminals, making the system more economical. Further, if necessary, mutual communication between remote devices can be made only by automatic dialing, and local monitoring and control can be performed by cooperation of each remote device.
