FIG. 4 is a side view showing how the environmental management information transmitting device 1 is used. Air conditioning outlet and inlet (not shown)
A receiving terminal 16 connected to a central processing unit CPU is installed on the ceiling of a building interior 20 equipped with a central processing unit CPU. As disclosed in Japanese Patent Application No. 61-183475, the receiving terminal 16 has a satellite-shaped main body divided into several blocks in the horizontal plane, each block is provided with a light receiving element and a light receiving element, and the outer surface is covered with a visible light cut filter. is covered.

Although the inside of the main body is not shown, it has the same components as the above-mentioned RCU plus a discrimination circuit, and communicates with the above-mentioned environmental philosophy information transmitting device 1 by open optical transmission, and also communicates with the central processing unit CPU. Environmental management information is exchanged using a line 9 between the two.

The device 1 may be hung on a wall at any location on the guide 20 using the hole 6 on the back side, or may be placed on a table or 17. Since the orientation of the transmitting/receiving section 5 differs depending on where this device is placed, operate the knob 4 to adjust the transmitting/receiving section 5 so that it correctly faces the receiving terminal 16 on the ceiling.

With this arrangement, data on the temperature, humidity, gas temperature, etc. of the guide 20 is sent from the transmitting/receiving section 5 to the receiving terminal (data station) 16 on the ceiling, and then collected in the central processing unit CPU. It compares the data with the room data and operates the air conditioner 18 to maintain the optimum conditions.

FIG. 5 shows an example in which the present invention is implemented in a special environment chamber 21 such as a radioactively contaminated chamber. A reaction zone and other working devices 22 are arranged in a chamber 21, and an unmanned measuring vehicle 23 is driven in front of the reaction zone. The device 1 is placed on an unmanned measuring vehicle 23, and data is optically transmitted between it and the receiving terminal 16 on the ceiling. An operator moves the unmanned measurement vehicle 23 in an operation room 24 adjacent to the room 21 and performs required work at each point.
