Abstract

PURPOSE:To eliminate the instaling work of signal lines at the change of terminal equipment by receiving and transmitting a data signal detecting the environmental state of each room through radio waves. CONSTITUTION:The terminal equipment 4 transmits a detected data signal through a radio type transmission/reception part 4a. A data repeater 5 receiving the data signal from the transmission/reception part 5a transmits the data signal from a radio type transmission/reception part 5b to a communication controller 6 through fine current. The data signal received by the controller 6 is sent to a central unit 7 through a transmission line 8. The equipment 7 displays information based upon the received data signal on a display. Consequently, it is unnecessary to execute the instaling work of signal lines at the change of the terminal equipment 4.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a building management device for managing building equipment and environmental conditions.

2. Description of the Related Art Generally, building management devices are installed for the purpose of monitoring and controlling various facilities within a building and monitoring and controlling the indoor environment.

This type of building management device had a configuration as shown in FIG. That is, the terminal device 10 that detects the indoor environmental condition is directly connected to the communication control device 11 via a wired transmission line 13 to transmit the detected data signal.

Further, the communication control device 11 transmits the detected data signal to the central device 12 through the transmission line 14, and the building supervisor monitors and controls the building based on the display of the central device 12.

Problems to be Solved by the Invention In such a conventional configuration, when adding a terminal device or changing the installation location due to changes in room partitions, changing the location of fixtures, etc., the terminal device and communication control device are The data signal transmission line between the two had to be reinstalled, and this work required a large amount of man-hours and labor costs. Furthermore, if it is not possible to add terminals or change the installation location, this causes a decline in the quality of the entire building management system.

The present invention solves these problems and provides a building management device that can significantly streamline the work involved in adding or changing terminals.

Means for Solving the Problems In order to achieve the above object, the building management device of the present invention comprises a central device that monitors and controls the environmental condition of the building, and a terminal device that is installed in each room of the building and detects the environmental condition. a communication control device that is installed at each location in the building and transmits data signals detected by the terminals to a central device and controls equipment according to commands from the central device; The data relay device wirelessly communicates the data signal detected by the device, and wirelessly relays the data signal to the communication control device.

Operation According to the present invention, with the above configuration, both the data repeater and the terminal device wirelessly receive and transmit data signals that detect the environmental conditions in each room. Therefore, when adding terminals or changing the installation location due to changes in the room layout, etc., only the placement and installation of the terminals and data repeaters need to be done.

Embodiment FIG. 1 is a block diagram showing an embodiment of the building management apparatus of the present invention. In FIG. 1, 1a is an outer wall of a building, 1b is a floor slab, 2 is a machine room partition, 3a is a ceiling, and 3b is a partition wall.

A terminal device 4 that is installed on the peripheral wall of each room of a building and detects indoor environmental conditions is a wireless transmitter/receiver unit 4 that communicates using infrared rays.
It has a.

The data repeater 5, which is installed mainly on the ceiling, has a wireless transmitter/receiver 6a that communicates using infrared rays on the exposed surface of the room, and a wireless transmitter/receiver 6b that communicates using weak radio waves on the exposed surface inside the ceiling. have. Furthermore, the communication control equipment #6 installed in each machine room of the building is connected to the central equipment that performs monitoring and control via a data signal transmission line 8, and the wireless signal transmitting/receiving unit 6a that communicates with the data repeater using weak electrical equipment is It is connected to a sun antenna 6b installed in the ceiling by a signal line 6c.

In the above configuration, the terminal device 4 transmits the detected data signal by the wireless transmitter/receiver 4a, and the wireless transmitter/receiver 5
The data repeater 5 which received the front data signal by a,
The data signal is transmitted from the wireless transmitter/receiver 6b to the communication control device 6 using weak radio waves. The communication control device 6 receives the data signal through the antenna 6b, but the strength of the weak radio waves is adjusted so as not to affect other floors.

The data signals received by the communication control device 6 are transmitted to the central device 7 via the transmission line 8 . The central device 7 displays information based on the received data signal on the display. Building managers perform monitoring and control operations based on this information. As a result, the central device 7 transmits control command signals for the equipment to the communication control device via the transmission line 8.

With the above-described configuration, when changing the installation location of the terminal device 4, only the installation work of the terminal device 4 is required.

Further, when adding a terminal device 4, the software such as address registration of the terminal device 4 must be slightly changed. Furthermore, if a new room is created by changing the partitions or the like, a new data repeater 5 and terminal device 4 may be installed on the ceiling of the room.

In the above embodiment, the communication control device 6 and the data repeater 6 communicate with each other using weak radio waves, and the data repeater 5 and the terminal device 4 communicate with each other using infrared rays. A wireless transmission method such as ultrasonic waves may also be used.

Effects of the Invention As described above, according to the present invention, there is no need to install signal lines when adding terminals or changing the installation location, so data can be placed on the ceiling of the room. This can be done at a low cost by simply installing a repeater and a new terminal on the wall, and its practical effects are significant.
