摘　　要：动态轨道衡计量是一种可以实现列车不停车不摘钩状态下称重的高效计量方式,它的工作原理及结构是:当列车通过秤台时,承重传力部分完成重量的传递工作;称重传感器在供桥电源的支持下,将重量信号转换成相应的电压信号并送入A/D转换器;A/D转换器把该电压信号转换为相应的数字信号,该数字信号通过CAN接口送入计算机,并由专门的计量软件计算并显示重量、速度、时间等信息,从而完成整个称重过程。Dynamic track scale measurement is an efficient measurement method which can realize the weighing of train without stopping and uncoupling,its working principle and structure are as follows:when the train passes through the weighing platform,the load-bearing part completes the weight transmission work;the load cell converts the weight signal into the corresponding voltage signal and sends it to the A/D converter under the support of the bridge power supply;the A/D converter converts the voltage signal into the corresponding digital signal,and the digital signal is sent to the computer through the CAN interface and sent by the special controller.The weight,speed,time and other information are calculated and displayed by the measurement software,so as to complete the whole weighing process.
