动态电子轨道衡是采用电子称重技术对在轨道上运行的货车进行动态称重的一种新型自动称重装置。由于它是在货车通过秤台时不停车、不脱钩的情况下快速进行称重,所以与静态机械轨道衡的称重方式相比,具有速度快、效率高、操作简便、劳动强度低、车辆周转快等优点。根据测试资料,由30节车皮组成的一列货车,用静态机械轨道衡称重需44.5分钟,而用动态电子轨道衡只要6分钟。表1对动态电子轨道衡与静态机械轨道衡的特点作了简要的对比。 Dynamic Electronic Track Scale is a new type of automatic weighing device that uses electronic weighing technology to dynamically weigh the truck running in orbit. Because it does not stop when the truck through the weighing platform, do not detach the case of rapid weighing, so compared with static mechanical rail scale weighing method, with high speed, high efficiency, easy operation, low labor intensity, vehicle turnover Fast and so on. According to the test data, a train of 30 wagons weighs 44.5 minutes with a static mechanical rail scale, whereas a dynamic electronic rail scale takes only 6 minutes. Table 1 on the dynamic electronic track balance and static mechanical track scale features made a brief comparison.
