Problems solved by technology

[0002] After the vehicle is loaded, the chassis of the vehicle will drop to different heights, corresponding to the different loads of the vehicle. According to this phenomenon, people have invented a distance measuring device to monitor the vehicle load, and it plays an important role in the logistics process. Function, it can prevent overloading or be used for data analysis of vehicle load. The damage and loss caused by overloaded transportation of trucks are shocking. The phenomenon of overloading has not improved. The signal or magnetic field of the existing distance measuring device interferes with the components during the measurement process. Many, the accuracy of distance measurement is not good, resulting in poor monitoring accuracy, the installation and disassembly of various components are inconvenient for maintenance and replacement, the protection effect of components is not good, and they are easy to be damaged. For this reason, we have introduced a measuring magnetic pole spacing Changing laser distance measuring device and its distance measuring method

Abstract

The invention discloses a laser distance measuring device for measuring magnetic pole spacing change and a distance measuring method thereof. The laser distance measuring device comprises a damper and a monitoring module; the damper comprises a damping piston cylinder fixed with a wheel assembly, a fixed flange seat fixed with a vehicle chassis and a piston rod at the output end of the damping piston cylinder, and the piston rod is sleeved with a damping spring; a square corrugated pipe is fixed between the upper supporting plate and the lower supporting plate, and a buffer spring is arranged in the square corrugated pipe; the monitoring module comprises a first Hall sensor, a second Hall sensor and a laser distance measuring sensor. The lower end of the supporting spring is connected with an electrode block. The overall structure occupies a small space and is convenient to disassemble and assemble; the distance between the magnetic poles is measured and calculated in two modes, measurement is convenient and fast, the average value is finally obtained, the accurate distance between the magnetic poles is obtained, errors caused by a single measurement means can be avoided, and the accuracy of vehicle load measurement is improved.

Description

technical field [0001] The invention relates to the technical field of laser distance measuring devices, in particular to a laser distance measuring device and a distance measuring method for measuring changes in magnetic pole spacing. Background technique [0002] After the vehicle is loaded, the chassis of the vehicle will drop to different heights, corresponding to the different loads of the vehicle. According to this phenomenon, people have invented a distance measuring device to monitor the vehicle load, and it plays an important role in the logistics process. Function, it can prevent overloading or be used for data analysis of vehicle load. The damage and loss caused by overloaded transportation of trucks are shocking. The phenomenon of overloading has not improved. The signal or magnetic field of the existing distance measuring device interferes with the components during the measurement process. Many, the accuracy of distance measurement is not good, resulting in poo...
