It is one of the most important measures to describe the basic characteristics of matter. The measurement of object quality is the most important event in history. In recent years, with the rapid development of the logistics industry, the vehicle weighing problems surfaced, how to accurately and quickly get the quality of the vehicle gradually get people's attention. Before the dynamic truck scale is developed, the weight of the vehicle is usually obtained in a static weighing manner. Although the accuracy of the static weighing of the vehicle is very high, the efficiency of the vehicle's static weighing is extremely low. Over the years, many countries have explored how quickly and accurately the vehicle has been weighed, and our country has developed unique technology in the dynamic weighing of vehicles.
First, the development of dynamic weighbridge
In the 1950s, Americans were inspired by the Germans and built highways in the country. However, the damage to the road was overcoming. The United States since 1953 to proceed to study the vehicle movement in the weight detection technology. And the first vehicle dynamic weighing technology research, laid the vehicle dynamic weighing technology based on the country is Hungary. However, early dynamic weighing systems were biased towards solving problems on the hardware, and the question of how sensors and tolerators were able to accurately reflect the pressure on their vehicles. Until the spring of 1976, from Japan's small wild Min Lang at the seventh IMEXO / TC3 conference published an important paper "dynamic weighing problem estimation theory application" for the vehicle dynamic weighing proposed different from the previous software solutions, Is a milestone in the study of dynamic truck scale from pure hardware to software breakthrough.
In the early 1980s, the first independent research and development of dynamic weighbridge and the results of the Chongqing Highway Science Research Institute, its research and development of SM2000 and SM3000 dynamic car weight system can be used in the road of automated traffic flow survey , Truck axle load test, limit limited to ultra-law enforcement and other fields, Shanxi Institute of Metrology and Taiyuan Institute of Technology has also been jointly developed, and finally developed a shaft weighing vehicle dynamic weighbridge. With the continuous development of highways, road vehicles overloading more and more serious, and a substantial increase in the transport of vehicles, but also to the original static weighing technology is becoming increasingly inefficient problem, so the dynamic weighing of the vehicle Resulting in a very large demand.
Dynamic weighbridge is a weighing platform and approach Road composed of dynamic road vehicle automatic weighing, according to the measurement method is not the same, the dynamic truck scale generally axis group (or shaft) heavy dynamic weighbridge, wheel heavy dynamic weighbridge, Dynamic weighbridge three styles.
