Description

Fire disaster prevention system utilizing RS485 communication line

In general, there are two types of fire detection methods, a heat detection type for detecting a fire at a high temperature of 70 ° C. or higher, and a smoke detection type for determining whether a fire is caused by smoke. Conventionally, the detection signal is a wired signal transmission line. It will be delivered with reference to Figure 1 attached to the configuration of such a conventional fire-fighting system as follows.

Typically, heat or smoke of 70 ° C. or higher is sensed by a sensor (not shown) and an abnormal voltage is generated by the detector 20, and the fire detection signal generated by this is fired with the repeater 30 through the signal transmission line 40. It is delivered from the sensing receiving board 10. At this time, the plurality of detectors 20 belonging to one repeater group 30 have the same ID code.

However, in the case of the heat sensing type, the coating of the signal transmission line 40 is lost even by the heat of 70 ° C. or less, so that a short circuit may cause the sensing signal not to be transmitted or an inaccurate signal may be transmitted. When invisible smoke occurs while the signal transmission line 40 is lost, the power supply is not supplied to the detector 20 so that the detector 20 cannot detect a fire. In addition, even if a fire is detected, a fire detection signal may not be transmitted to the repeater 30.

Due to the signal transmission line 40, the first time of construction and repair of the facility has to break down the wall or in consideration of the signal transmission line 40 in advance to design a building, and the installation cost of the fire protection facility 20 and the repeater 30 There is a problem in that the construction cost is increased by adding the labor cost of personnel required for the installation and the signal transmission line 40 ratio between).

In particular, the plurality of detectors 20 belonging to one repeater 30 group has the same ID code, there was a problem that can not determine the exact location of the fire.

Therefore, the above problems can be summarized in terms of administrative burden and maintenance of complicated communication line because it is not easy to identify the location of fire due to the cost burden due to the increase of the complexity of communication line and the multiple detectors grouped together in one repeater. The burden is presented as a problem.
