Monitoring system and monitoring method for measuring total weight of vehicle in real time

The invention discloses a monitoring system and monitoring method for measuring the total weight of a vehicle in real time. The monitoring system comprises a TPMS, a tire and road contact length measuring system, a vehicle total weight calculating system and a real-time alarm monitoring system. The monitoring method mainly includes the following steps that: the TPMS measures the air pressure inside each tire of the vehicle, the tire and road contact length measuring system measures curvature data and distance data, the vehicle total weight calculating system calculates a tire and road contactlength, the contact area of each tire and a road surface, the load of each tire, the shaft weight of each vehicle shaft and a total weight of the vehicle, and the real-time alarm monitoring system transmits the data to a driver and a regulation department. The invention has the characteristics of high precision, stable system and convenient installation and operation, the supervision of vehicle overload and over-limit ill
