Problems solved by technology

However, the existing problem is that this installation process is difficult to achieve a weighing accuracy of more than 90%, and the data stability is very poor. Generally, the calibrated parameters on the A road surface will basically fail when they reach the B road surface, and the road surface must be calibrated one by one. , the debugging process of the system is very complicated and time-consuming, and the consistency is poor

Abstract

The invention provides a device and a method for improving the consistency of a piezoelectric film weighing sensor. The device comprises a piezoelectric film weighing sensor, a plurality of fixing clamps, and a U-shaped through. The piezoelectric film weighing sensor comprises a first connector part, a second connector part and a sensing part; one end of the sensing part is connected with the first connector part and the other end of the sensing part is connected with the second connector part; the multiple fixing clamps are used for fixing the sensing part of the piezoelectric film weighing sensor; the first connector part is located at one end of the U-shaped trough and the second connector part is located at the other end of the U-shaped trough; the multiple fixing clamps are fixed to the center of the U-shaped trough in parallel in an equally-spaced manner. Thus, the piezoelectric film weighing sensor can be installed at the same height and the problem of poor consistency of a piezoelectric film weighing sensor caused by different heights of roads and non-uniform hardness of road surfaces, is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle weighing, in particular to a device for improving the consistency of a piezoelectric film weighing sensor and a method for improving the consistency of a piezoelectric film weighing sensor. Background technique [0002] At present, the piezoelectric film weighing sensor is widely used in the road dynamic weighing system. Most manufacturers adopt the installation process guided by the manufacturer, that is, open a 2-2.5cm wide and 4cm deep groove on the road surface, and weigh the piezoelectric film. The sensor is buried directly. However, the existing problem is that this installation process is difficult to achieve a weighing accuracy of more than 90%, and the data stability is very poor. Generally, the calibrated parameters on the A road surface will basically fail when they reach the B road surface, and the road surface must be calibrated one by one. , the debugging process of the system is ve...
