Description

technical field [0001] The invention relates to a dynamic weighing detection device, in particular to a multi-point combined dynamic weighing detection device. Background technique [0002] In order to curb overloaded transportation, in recent years, people have set up toll booths at the entrances of highways, bridges, etc., and adopted the method of charging by weight, and the infrastructure of charging by weight is the vehicle weighing device. In order to speed up the speed of charging by weight and avoid the phenomenon of vehicle queuing, dynamic weighing devices are more and more widely used. The working principle of the dynamic weighing device is: after the dynamic driving vehicle passes through the weighing platform with the sensor installed, after the force-bearing object is deformed, the sensor and the force-bearing object attached to the force-bearing object deform synchronously, so that the sensor output and the force-bearing object are deformed synchronously. The...

Problems solved by technology

Most of the existing dynamic weighing platforms are installed in the groove of the pavement foundation, and the sensors are set under the weighing platform. There are blank areas at both ends of some weighing equipment. Without sensors, it is impossible to detect, overrun or overweight The driver took the opportunity to detour, creating abnormal driving phenomena such as side slipping or changing lanes in the weighing area, evading detection, causing the weighing system to misjudge the vehicle model and the number of axles; the sensor position of some weighing equipment is single, and the detection is single. For vehicles with a large amount of liquid, the liquid will shake during driving, resulting in unstable force of the force-bearing object, resulting in a decrease in detection accuracy
