Automobile dynamically weighing sensing device

Abstract

This invention relates to a kind of automobile dynamic weight sensing device that belongs to electronics region. The invention includes: high pressure-proof spherical rubber gasbag, pressure gauge, signal transmission cable valve, pressure mounting body, and pressure carrying steel body. up and down of the two high pressure-proof spherical rubber gasbag all swing joint one pressure mounting body that possess equality sectional area; the upper pressure mounting body and lower pressure mounting respectively fastening seal with upper pressure carrying steel board and lower pressure carrying steel board; upper section of two rubber gasbag enclose one pressure gauge and one valve, and pressure gauge via signal transmission cable to connected to next systemic data acquisition passage. Utilize the constant immovability of contact area between upper pressure mounting body and high pressure proof rubber gasbag, the measured pressure value multiplied by the active area to gain gravitation of the measured wheel's point of force application, then by preset axletree's Quality Mathematics mass Model to count the axletree quality, and then to obtain entire car quality.

Description

technical field [0001] The invention relates to a sensing device in the field of electronic technology, in particular to a sensing device for dynamic weighing of automobiles. 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. To completely avoid and stop the occurrence and existence of this kind of phenomenon, in addition to strengthening and perfecting 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 in solving it to improve the level of monitoring automation technology.

Problems solved by technology

The effectiveness of the whole technology for weighing automobiles is worthy of recognition, but technical defects exist therein: 1. When automobiles with different loads extrude the pressure oil pipe of this invention technology, since the extruded contact area is not constant, and has extreme Large randomness, so it is difficult to establish an accurate expression between the pressure value obtained by sensing and the mass (or weight) of the measured axle, in other words, it is difficult to accurately determine the measured weight and pressure; 2 2. When re-arranging the pressure oil pipes, it is necessary to "according to different needs, arrange the pressure oil pipes perpendicular to the driving route of the vehicle or at a certain angle, or arrange the oil pipes in steps on the road surface, and arrange multiple oil pipes at the same time." A strict condition of use is added to this technology in practical application, and the vibration caused by the inevitable vehicle extrusion can destroy any original precise position arrangement at any time, so this invention technology will lose its basic practicality value
