| The vehicle type electronic truck scale as highway weight charge system of key equipment, is used as the basis of cars overrun overload, has the force of law. The accuracy of the vehicle type electronic truck scale weighing becoming the key factor of weight charge system.At present, the vehicle type electronic truck scale verification regulation for blank, for the first time in our province to compile the vehicle type electronic truck scale verification regulation, develop targeted, content, perfect testing method, so as to adapt to the needs of the development of the market. As our province highway construction, the rapid development of the technology for weight, measurement unit based on the principle of fairness and justice, to maintain normal order road weight charge of responsibility. Technical indicators for the weighing device and the influence of particular concern for cases, combined with the actual detection problem, on the stability of the vehicle type gauge heavy truck scale, repeat performance assessment, performance evaluation of uncertainty of measurement results, analysis of the factors of data deviation, customization and effective detection method, ensure the vehicle type electronic truck scale data accurate and reliable.On the other hand, make an analysis for multi-sensor compensatory, using neural network multisensor data fusion technology, increase the weighing accuracy. Vehicle type electronic truck scale core parts is more than the balance of body at the bottom of the sensor, the accuracy of each sensor output data is related to truck scale other properties, such as: linear can influence, weighing, repeatability, lead to the weighing data is not real. Using neural network technology to redistribute the weight of each sensors, achieve compensation, reduce artificial debugging difficulty, demonstrate its intelligence level. |
