Embodiment Construction
[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0039] In the prior art, there are often cases where the fine measurement weighing equipment is abnormal, but the rough measurement weighing equipment cannot accurately measure the vehicle weight. In order to solve the problems existing in the prior art, the present invention utilizes the fine measurement and weighing equipment to calibrate the rough measurement and weighing equipment, so that the vehicle weight obtained by the rough measurement and weighing eq...

The present invention provides a method and device for calibrating weighing equipment. The calibrating method for weighing equipment includes: acquiring in real time the first vehicle characteristic information of vehicles passing through the first weighing equipment; Vehicle characteristic information, the weighing accuracy range of the second weighing device is greater than the weighing accuracy range of the first weighing device; according to the first vehicle characteristic information and the second vehicle characteristic information, the The vehicle is logically matched with the vehicle passing through the second weighing device; the first vehicle characteristic information of the successfully matched vehicle is calibrated according to the vehicle weight information in the second vehicle characteristic information corresponding to the successfully matched vehicle. The present invention can use the calibrated coarse measurement weighing equipment to carry out individual weighing, and can also carry out combined weighing with the fine measurement weighing equipment to obtain more accurate measurement results.
Description
technical field [0001] The invention relates to the technical field of dynamic weighing, in particular to a weighing equipment calibration method and device. Background technique [0002] In recent years, with the country's economic development and trade expansion, the traffic volume has gradually increased. However, there are over-limit standards stipulated by relevant departments on the road. If the vehicle is over-limited and overloaded, it will seriously damage the road, and serious damage will increase maintenance. Costs and increased traffic accidents. Therefore, it is of practical significance to detect the vehicle weight by dynamic weighing. [0003] Dynamic weighing technology can be divided into low-speed weighing and high-speed weighing. Low-speed weighing is currently widely used, the technology is relatively mature, and the weighing accuracy is also high. At present, most of the domestic weighing toll stations use low-speed weighing equipment and technology. ...
