In general, the Ground Common Duct is designed to improve the aesthetics of the ground by accommodating underground facilities such as electricity, gas and water supply facilities, communication facilities, and sewage facilities, and to preserve the road structure and facilitate traffic communication. It refers to a facility installed underground, and it is installed to extend from several hundred meters to several kilometers depending on the installation site or purpose. Here, since the underground tunnel is installed underground, air circulation with the outside is limited as well as toxic or combustible gas may be generated from the inside, so a ventilation system for forced ventilation is essential when gas is generated.

As shown in FIG. 14 , the ventilation system includes a ventilation fan 40 that ventilates the inside by discharging internal air to the outside or sucking in external air to the inside while rotating the impeller, and driving control of each ventilation fan 40 . It was composed of a fan control module 50 for this purpose, and a gas sensor 60 that transmits a detection signal for detecting toxic or combustible gas to the fan control module 50 . Accordingly, when the gas sensor 60 detects a gas above a threshold value, the fan control module 50 rotates and drives each ventilation fan 40 to quickly discharge the generated gas to the outside.

In addition, in order to detect gas over the entire underground tunnel 10, a plurality of gas sensors 60 must be arranged at regular intervals as shown in the drawing, but in order to supply driving power to each gas sensor 60, an external Since the sensor power supply line (L1) extended from the power source had to be installed together, there was a problem in that the construction cost and construction time for establishing the ventilation system increased, and the maintenance cost increased.

Moreover, in order to transmit the detection signal sensed from each gas sensor 60 to the fan control module 50, since the sensor signal transmission line L2 has to be built separately from the sensor power supply line L1, the construction cost However, there was a problem in that the construction time and maintenance cost were further increased. In addition, in the case of public facilities, periodic safety inspections are performed for each set period, and since the sensor power supply line (L1) and the sensor signal transmission line (L2) are also reflected as items of safety inspection, there is a problem that the safety inspection requirement increases. there was.

On the other hand, as shown in FIG. 14 , a plurality of lighting devices 20 are arranged at intervals of approximately 4 m to 5 m along the extended length in the underground cavity 10 to provide lighting to work in the internal space. And, the light-off switch 30 was disposed at intervals of approximately 100 m to 300 m, so that the lighting devices 20 included in each interval could be turned on and off in an integrated manner. However, as shown in the drawing, a lighting system must be installed because a lighting-on signal line (L3, normally a 3-way switch construction) for signal connection between the turn-off switch 30 and each lighting device 20 must be installed. There was a problem in that the construction cost and construction time for this purpose increased significantly, and the maintenance cost and safety inspection requirements were further increased.
