The invention provides a tire load intelligent monitoring method and device, a magnetic sensor measures the magnetic force on each tire of a vehicle and converts the magnetic force into a voltage signal, and a sensor processor converts the voltage signal into a function of the variable quantity of the tire height and the voltage signal; the ultrasonic sensor measures time data, the temperature sensor measures temperature data, the sensor processor compensates the sound velocity, and the compensated sound velocity and distance data are utilized to calculate the distance variation from the suspension of the vehicle to the ground; the sensor processor calculates the tire pressure amount, the load capacity borne by each tire and the total load capacity of the vehicle according to the variable quantity x of the height of the magnetic strip and the variable quantity of the distance from the suspension of the vehicle to the ground; the control unit compares the total load capacity of the vehicle with the limited load capacity of the vehicle and judges whether the vehicle is overweight; comparing the loading capacity between the tires of the truck, and judging whether the truck is overweight or not; and a driver is reminded to adjust the distribution of the cargos or supplement air or replace the tires.
Description
technical field [0001] The invention relates to a tire load intelligent monitoring method and device. Background technique [0002] In recent years, in the high-speed driving of automobiles, tire failure is an important reason for sudden traffic accidents. Statistics show: the main cause of traffic accident increase is the blowout caused by tire failure in high speed driving. The main cause of a flat tire is that the tire pressure is too low or too high. The overweight and overweight phenomenon of road transport vehicles in my country is very common. In some areas, freight vehicles will have a certain degree of overweight and overweight. [0003] In order to suppress the phenomenon of vehicle overweight, extensive research has been carried out on tire failure prevention and tire overweight detection technology at home and abroad. Studies have shown that maintaining normal tire pressure and temperature during driving and timely detection of tire underpressure, air leakage ...
