Abstract

The invention provides a vehicle-mounted liquid security check channel of a bus. A left side plate and a right side plate of a door frame are provided with a first laser infrared distance measurement instrument and a second laser infrared distance measurement instrument respectively, a capacitance measurement system comprises a first conductive plate and a second conductive plate, a central controller is provided with a calculation unit, the calculation unit calculates to obtain a dielectric constant epsilon of measured liquid, and the central controller is further provided with a comparison unit judging whether the measured liquid is safe or not. Due to a large difference between a dielectric constant epsilon of flammable and combustible liquid and a dielectric constant epsilon of safe liquid, safety of the liquid can be assessed according to the dielectric constant epsilon obtained after measurement. The vehicle-mounted liquid security check channel occupies a little space and can be conveniently installed on the bus and cannot influence operation of the bus and traveling of citizens.

Description

technical field [0001] The invention relates to a vehicle-mounted liquid security inspection channel. Background technique [0002] As the main means of transportation for the general public, buses have the disadvantages of high mobility, dense personnel and inconvenient security checks, which give criminals a great opportunity and cause hidden dangers to the lives of passengers. At present, security inspection equipment is mainly used in bus stations, railway stations or airports, but because the security inspection equipment is too large to be installed in buses, urban buses have not been equipped with security inspection equipment. [0003] In recent years, because passengers carry flammable and explosive materials, many bus burning accidents have been caused, and a large number of casualties have been caused. According to statistics, flammable and explosive items are mainly carried on the vehicle in liquid form, including liquid explosives, gasoline, acetone, ethanol, e...
