Non-stop weighing method of four-segment combined weighing system

Abstract

The invention belongs to the field of dynamic weighing of a road lorry, and particularly relates to a non-stop weighing method of a four-segment combined weighing system. A hardware platform of the no-car-stopping weighing method of the four-segment combined weighing system is a four-segment combined scale platform; and the four-segment combined scale platform comprises an infrared transmitting light curtain, a first-segment shaft set scale platform, an embedded shaft recognizer A and an embedded shaft recognizer B at the front end and the back end of the first-segment shaft set scale platform, a subsequent integral scale platform which is formed through overlapping a second-segment scale platform, a third-segment scale platform and a fourth-segment scale platform, and an embedded shaft recognizer C at the back end of the subsequent integral scale platform. The non-stop weighing method is advantageous in that the shaft set scale platform and the two shaft recognizer at the front end and the back end of the scale platform can measure the car speed and the motion direction, thereby effectively preventing cheating, dynamically measuring the shaft weight and calculating the total weight; the integral scale platform and the shaft recognizer at the back end of the scale platform determines a fact that a certain shaft of the vehicle drives on the scale platform or drives away from thescale platform and perform dynamic measurement for obtaining the shaft weight and the total weight. The dynamic weighing method according to the invention realizes dynamic redundant accurate weighing.

Description

technical field [0001] The invention belongs to the field of dynamic weighing of road trucks, and in particular relates to a non-stop weighing method of a four-section composite weighing system. Background technique [0002] The expressway implements weight-based tolling, and the total weight of the vehicle is measured for toll collection, and the axle load of the vehicle is controlled to protect the roadbed and bridge safety of the expressway. The known weighing method is one car, one rod, one stop, and one weighing. The advantage of this weighing method is that it can be accurate and there is no weighing dispute. The disadvantage is that the weighing speed is slow. With the rapid economic growth of our country, there are more and more heavy-duty vehicles, and it is common for vehicles to be crowded at the entrance of the expressway. In order to solve the "vehicle congestion in the weighing channel at the entrance of the expressway" and improve the traffic efficiency, the ...
