Abstract
The invention discloses a method of using a satellite positioner as an urban gas pipe network leak positioning alarm. The gas plays a very important role in the daily life of the urban citizens. However, since gas leak often leads to accidents, a method of taking the satellite positioner as the urban gas pipe network leak positioning alarm is urgently needed. The method is that the satellite positioner does not work in regular time; the satellite is triggered to work immediately after the trigger detects the gas leak information; the J-S closes the power switch of the satellite positioner to let the satellite positioner work; the accurate position is displayed on the computer immediately after the satellite positioner receiving system receives the danger positioning information. The invention is applicable to the gas pipe network leak alarming.
Description
Technical field:
The present invention relates to a kind of gas alarm method, be specifically related to a kind of method of utilizing the gps satellite steady arm to make the town gas pipe network leakage locating alarming.
Background technology:
The use of coal gas plays important effect in the daily life of city, but because but generation again and again of the accident that gas leak causes, so gas leak detection problem has become technician's problem demanding prompt solution.
Summary of the invention:
The purpose of this invention is to provide a kind of alarm method that utilizes the gps satellite steady arm to make the town gas pipe network leakage locating alarming.
Above-mentioned purpose realizes by following technical scheme:
A kind of method of utilizing the gps satellite steady arm to make the town gas pipe network leakage locating alarming, satellite locator is not worked at ordinary times, after detecting gas leak information, triggers by trigger satellite locator work at once, make its work by the closed satnav appliance mains switch of J-S, so the satellite locator receiving system receives the dangerous situation locating information, demonstrate the accurate position of accident by computing machine at once.
This technical scheme has following beneficial effect:
1. the inventive method is fairly simple in implementation process, is quick on the draw, and can detect the gas leak problem fast and accurately.
2. utilize the inventive method to carry out gas leak and detect, by information transmission detected danger signal is passed to inspection center, inspection center just can detect the site of an accident in time, thereby has guaranteed the safety of people when using coal gas.

The specific embodiment of the present invention:
Embodiment 1:
Utilize the gps satellite steady arm to make the method for town gas pipe network leakage locating alarming, the gps satellite steady arm, this part real work situation is: the gps satellite steady arm is not worked at ordinary times, in case trigger triggers the work of gps satellite steady arm at once after detecting gas leak information, by the J-1 closure, the GPS power switch makes its work send information, and gps satellite steady arm receiving system receives the dangerous situation locating information.The around the clock service in 24 hours of this system, in case after receiving the dangerous situation locating information of gps satellite steady arm transmission, demonstrate the accurate position of accident by computing machine at once, this system can be rescue strive the quality time, because gps satellite steady arm and receiving system are mature technologies in this system, need not to debug the work that gets final product so buy.
The principle of work of gas leak trigger circuit, the resistance of QM-N10 gas sensing diode in pure air is nearly tens kilo-ohms as shown in Figure 2, when touching coal gas, resistance sharply descends, fall is being directly proportional below 0.5% with gas concentration, comprise in this product that a slice has four two input nand gate cmos circuits and forms, by IC
