introduction
80% of the toll roads in the world are located in China. Since.2003, various provinces and cities in my country have successively implemented weight-based toll roads. Several toll roads have been installed on the market.
Ten thousand sets of various types of highway automatic weighing instruments are widely used in expressway toll-by-weight and over-limit detection business. Based on years of research and
With the development and progress of technology, there is a trend of diversification of road automatic weighing instruments. Each type has its own unique characteristics.
There is a big gap, but in general, it is basically necessary to provide reliable vehicle gross weight information, as well as axle weight and axle group weight information. Due to product structure
The products have been developed in different production fields, such as. vehicle type, axle load type, and flat panel module type are developed in weighing instrument production plants; bent plate type mining
The load cell technology is used, so it has been developed in the load cell industry; the quartz crystal type uses semiconductor technology, and is generally used in the exchange
development of the transportation industry. It is difficult for a single product standard to cover all types, and a governing technical standard is required to cover all types, and according to
According to the different product structures, determine the corresponding accuracy level and inspection rules.
During the dynamic driving process of the road vehicle, the dynamic road vehicle is automatically adjusted according to the different bearing modes of the loader of the automatic scale to the wheel.
Scales are divided into two categories, namely full load-bearing type (vehicle type and flat panel module type) and partial load-bearing type (axle load type, curved plate type, quartz crystal type, flat plate type)
modular). Dynamic road vehicle automatic weighing instruments (WIM) are divided into three categories according to the maximum operating speed for which the weighing instrument is designed. low-speed WIM
(The operating speed range of LS-WIM weighing instruments and systems is 0km/h< v≤10km/h), medium speed WIM (MS-WIM weighing instruments and systems
The operating speed range is 0km/h< v≤40km/h), and the operating speed range of high-speed WIM (HS-WIM weighing instruments and systems is
0km/h< v≤100km/h).
The formulation of GB/T 21296 "Automatic Weighing Apparatus for Dynamic Road Vehicles", on the one hand, is an objective requirement for the development and changes of international standards, and on the other hand, it is also a
It is an urgent requirement of my country's complicated application status, and will greatly support the healthy development of the dynamic road vehicle automatic weighing instrument industry.
effect.
GB/T 21296 consists of 6 parts.
--- Part 1.General technical specifications;
--- Part 2.Vehicle type;
--- Part 3.Axle-loaded;
--- Part 4.Bending plate type;
--- Part 5.Quartz crystal formula;
--- Part 6.Flat modular.
