Laser distance measuring device and method for measuring distance between magnetic poles

Abstract

The invention discloses a laser distance measuring device and a distance measuring method for measuring changes in magnetic pole spacing, including a shock absorber and a monitoring module. The shock absorber includes a shock absorbing piston cylinder fixed to a wheel assembly, and a fixing method fixed to a vehicle chassis The blue seat and the piston rod at the output end of the shock-absorbing piston cylinder, the piston rod is sleeved with a shock-absorbing spring; a square bellows is fixed between the upper support plate and the lower support plate, and a buffer spring is arranged inside the square bellows; the monitoring module includes The first Hall sensor, the second Hall sensor, the laser ranging sensor, and the lower end of the support spring are connected with an electrode block. The overall structure of the present invention occupies a small space and is convenient for disassembly and installation; the magnetic pole spacing is measured and calculated by two methods, which is convenient and quick to measure, and finally calculates the average value to obtain an accurate magnetic pole spacing, which can avoid errors caused by a single measurement method and improve Accuracy of vehicle load measurement.

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...

[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
