The invention discloses a single chip microcomputer-based dynamic automobile weighing system comprising a weighing sensor, a signal amplification circuit, an A / D converting circuit, a single chip microcomputer, a display circuit and a PC machine, wherein the weighing sensor is connected with the signal amplification circuit, and the signal amplification circuit is connected with the A / D converting circuit; the single chip microcomputer is connected with the A / D converting circuit, the display circuit and the PC machine. According to the single chip microcomputer-based dynamic automobile weighing system, the system automatically enters a dynamic weighing mode when a vehicle moves onto a weighing platform and weight data received by an instrument from the weighing platform exceeds a certain limit value; when the vehicle passes through the weighing platform, vehicle weight is detected by the instrument, a data collection module in a control box is used for amplifying signals sent from the weighing platform, and the signals are converted into digital signals that are sent to a computer for weighing signal processing operation; an axle overload quantity, a total overload quantity and relevant content are automatically calculated, recorded and stored after information transmitted from the instrument is received by a computer.
Description
technical field [0001] The invention relates to a dynamic weighing system, in particular to an automobile dynamic weighing system based on a single-chip microcomputer. Background technique [0002] Today, our country is increasing its efforts to build road infrastructure, especially expressways. The development of the transportation industry has undoubtedly played a positive role in promoting the construction of the national economy. There are many aspects, such as accelerated damage to the road surface, increased road maintenance costs, frequent traffic accidents, damage to accelerated vehicles, etc. Therefore, it is becoming increasingly important to strengthen the management of road transportation and ensure driving safety. Designing high-precision dynamic The truck scale will surely provide an effective technical means for the road operation department to control over-limit and overload and implement weight-based toll collection. At the same time, it is still an unsolve...
