Abstract

The invention discloses a vehicle risk instrument gas-sensitive automatic detection device and an automatic detection method thereof. The vehicle risk instrument gas-sensitive automatic detection device comprises a test cabinet body, a standard gas supply part and a compressed gas source supply device, wherein a blowing nozzle is arranged in the test cabinet body, and the blowing nozzle and a to-be-tested vehicle risk instrument placed on a laminate are arranged in a face-to-face mode; the input end of the blowing nozzle is in control connection with the standard gas supply part through a pipeline and a standard gas input control valve, and the compressed gas source supply device is in control connection with the blowing nozzle through a gas source pipeline and a blowing gas input control valve; and the standard gas supply part, the compressed gas source supply device, the standard gas input control valve and the blowing gas input control valve are in control connection with the detection controller. The device can accurately provide standard gas for detection during inspection and testing, is not influenced by external environment during testing, is high in detection precision and detection speed, is suitable for accurately detecting the vehicle risk instrument in batches, can realize automatic detection, can greatly improve the capacity of the vehicle risk instrument, and can ensure the quality of the vehicle risk instrument.

Description

technical field [0001] The invention relates to the technical field of gas detection instruments, in particular to a gas-sensitive automatic detection device and an automatic detection method for a vehicle hazard instrument. Background technique [0002] At present, the flammable and explosive oil gas molecular detector for vehicles (referred to as the vehicle risk instrument) developed by the applicant has been used in batches on buses to check whether passengers carry gasoline and other flammable and explosive dangerous goods with them. As governments at all levels increase their awareness of public safety, the demand for vehicle safety instruments has increased sharply. At present, applicants need to continuously expand production capacity to meet market demand. Since the car risk meter is a new product independently developed by the applicant, there is no special production equipment and production line on the market. In order to increase production capacity, it is parti...
