Pneumatic system leakage alarm and detection system and method

Abstract

The invention discloses a leakage alarm and detection system and method for a pneumatic system. The system comprises a main gas supply switching branch and a gas coloring device, and the interior of the gas coloring device is provided with a plurality of gas dyeing mediums with set colors; the pressure alarm switch is connected with the pneumatic system and used for sending an alarm signal when the pressure of the pneumatic system is lower than a preset value; the light intensity sensor is used for detecting and outputting a current ambient light intensity signal; and the electric control system is in circuit connection with the main gas supply switching branch, the gas coloring device, the pressure alarm switch and the light intensity sensor respectively, and is used for closing the maingas supply switching branch when receiving the alarm signal and controlling the gas coloring device to dye the gas into a corresponding color according to a current ambient light intensity signal output by the light intensity sensor. Detection personnel can quickly and accurately identify leakage and judge leakage points, and the device is concise, efficient, time-saving, labor-saving, high in efficiency, simple in structure, high in automation degree, safe and reliable.

Description

technical field [0001] The invention relates to the field of air leakage detection, in particular to a pneumatic system leakage alarm and detection system and method. Background technique [0002] At present, many engineering vehicles, such as cleaning vehicles and sweeping vehicles, use a large number of pneumatic systems to control the on-off of low-pressure waterways and high-pressure waterways, and then control the sprinkling and spraying of the waterways of the entire vehicle. Compared with the commonly used hydraulic system, the pneumatic system has the advantages of no pollution, low cost and convenient installation. [0003] A conventional pneumatic system consists of an air source, a safety valve (manual air valve), a filter, an electromagnetic valve group and a cylinder. The medium used in the pneumatic system is high-pressure gas from the chassis. [0004] When there is a leak in the pneumatic system, it is not easy to have obvious stains and oil like the hydrau...
