Device for sensing carload

Abstract

The invention is the automobile load sensing device and belongs to the self-recognition system of overloading technology. The invention comprises the extreme pressure rubber gas cell, the main pressure sensor, the assistant pressure sensor, the primary signal transmitting cable, the primary signal transmitting redundant cable, the secondary signal transmitting cable, the secondary signal redundant cable. The extreme pressure rubber gas cell conveys the sensed pressure to the main and the assistant pressure sensors in the sealed chamber; the output signals of the main and the assistant sensors are led separately by the primary and the secondary signal transmitting cables; the primary and the secondary redundant cables are separately the repeating channels of the primary and the secondary transmitting sensors. The invention has stable and reliable operation.

Description

technical field [0001] The invention relates to a sensing device used in the technical field of an automatic overload identification system for an automobile, in particular to an automobile load sensing device. Background technique [0002] In our country, the phenomenon of truck overloading and illegal refitting and loading is very serious, causing most roads and bridges to be in an overloaded state for a long time, which not only seriously affects the service life of roads and bridges, but also causes frequent traffic accidents during vehicle driving, especially in a certain Some highways are even more overwhelmed and dangerous. In order to completely avoid and stop the occurrence and existence of such phenomena, in addition to strengthening and perfecting the construction of the traffic legal system and establishing a scientific management system, it is very important to have a set of modern scientific and technological means to assist the solution and improve the degree ...

Problems solved by technology

The above technical performance is worthy of recognition, but this technology uses "rubber pressure oil pipe", plus "pressure sensor", and then uses "manual pump" to fill the "rubber pressure oil pipe" with oil, obviously there are three major technical defects:( 1) Oil is an incompressible fluid, and the internal volume of the oil pipe will be seriously deformed and expanded with the increase of the load, which will cause a great error in pressure transmission; (2) Assembled load sensing device, its The sealing performance of the internal fluid is difficult to guarantee, which will inevitably lead to a great reduction in its practicability; (3) In addition, it is equipped with a "manual pump" for oil filling, and it must be equipped with a corresponding oil pressure calibration device in practice, resulting in a further decline in its practicability
