Embodiment Construction

[0011] The specific embodiment of the present invention is described in detail now in conjunction with accompanying drawing:

[0012] The present invention is mainly composed of an upper plate part 1 and a lower plate part 8, and the upper plate part 1 is composed of an upper insulator 2, an upper shielding plate 3 and a capacitor upper plate 4, and the lower plate part 8 is composed of a capacitor lower pole Plate 5, lower shielding plate 6 and lower insulator 7.

[0013] The upper shielding plate 3 and the capacitor upper plate 4 are sealed in the upper insulator 2 , and the capacitor lower plate 5 and the lower shielding plate 6 are sealed in the lower insulator 7 .

[0014] The upper plate part 1 is installed on the bottom of the compartment through the hole 10, the lower plate part 8 is installed above the middle part of the axle through the hole 9, and the capacitor upper plate 4 and the capacitor lower plate 5 are aligned up and down. A set of capacitive sensors are mo...

Abstract

The present invention belongs to a vehicle-mounted type capacitive transducer for sampling vehicle load. Its key lies in that it mainly composed of capacitance upper electrode plate and capacitance lower electrode plate, the upper electrode plate is mounted in the bottom portion of platform, the lower electrode plate is mounted over the middle portion of wheel axle, two electrode plates are face-to-face oppositely and up-down mounted, over the every wheel axle of the vehicle a set of capacitive transducer is mounted respectively. Besides, said invention also provides the working principle of said vehicle-mounted type capacitive transducer and its operation method and steps for detecting vehicle load mass.

Description

1. Technical field [0001] The invention relates to a vehicle-mounted capacitive sensor for vehicle load sampling. 2. Background technology [0002] In recent years, the phenomenon of overloading of road transport vehicles in my country is very common. The overloaded transportation of vehicles has induced a large number of road traffic safety accidents, seriously damaged the road infrastructure, and led to vicious competition in the road transportation market. [0003] At present, my country's highway department controls vehicle overloading entirely by weighing methods. There are three types of vehicle weighing instruments: electronic platform scale (also known as electronic truck scale), dynamic axle load meter and portable weighing instrument. Electronic platform scales are used for static weighing of vehicles at vehicle overload checkpoints, and dynamic axle load meters are used for dynamic weighing of vehicles at highway toll stations, both of which are installed in fix...
