Problems solved by technology

However, engineering practice has found that due to factors such as terrain and environment, the distribution of gas concentration is often not the highest at a certain point under ideal conditions, but is distributed regionally, so general techniques cannot achieve high-precision and rapid location of leak points

Embodiment Construction

[0009] Such as figure 1 A new type of gas leakage locating device shown includes a gas concentration detection unit composed of a plurality of methane sensors, the signal output end of the gas concentration detection unit is connected with the signal input end of a microprocessor, and the signal output end of the microprocessor is The signal output end is respectively connected with an audible and visual alarm circuit and a data display unit, and the microprocessor is provided with a USB external extension unit. Data can be uploaded to PC in time.

[0010] When the present invention works, the methane sensor transmits the gas concentration data detected by the sensor to the microprocessor through the gas concentration detection unit, and the microprocessor calculates the concentration change rate and calculates the possibility that the current point is a leak point according to the concentration and the change rate. Finally, the result is displayed to the user through the sou...

Abstract

The invention discloses a novel positioning device for fuel gas leakage in the field of security detection devices. The novel positioning device comprises a fuel gas concentration detection unit, wherein the fuel gas concentration detection unit comprises a plurality of methane sensors; a signal output end of the fuel gas concentration detection unit is connected with a signal input end of a microprocessor; and a signal output end of the microprocessor is connected with a sound-light alarm circuit and a data display unit respectively. According to the novel positioning device for the fuel gas leakage, concentration of methane in the position of each sensor is measured, so that a fuel gas leakage position can be positioned accurately, a leakage point can be found in time, a fault can be eliminated, the safety performance is improved, and the device is applicable to detection of fuel gas leakage.

Description

technical field [0001] The invention relates to a safety detection device, in particular to a gas leakage positioning device. Background technique [0002] With the adjustment of the country's energy structure and the improvement of people's living standards, gas has become an important energy source for national production and life. The main consumption terminals of gas are mostly in cities, and the gas supply pipeline network is mainly concentrated in densely populated areas. In the underground of the highway, the branch network is distributed in the buildings and indoors, and leakage incidents caused by corrosion, cracks and other reasons occur frequently. In the slightest, it will cause resource waste and environmental pollution; in severe cases, it will cause explosion, fire, poisoning, endanger the lives and property safety of users and surrounding population, and bring immeasurable losses to the society. [0003] Leakage repairs and regular security inspections of ga...
