微机动态轨道衡是一种动态称重设备,能对通过的列车逐节准确称出车厢的重量。运行时,列车在行进,车厢在振动、冲撞。模拟通道中传送的称重信号经过传感器、放大器,A/D转换器等设备多次变换;这些设备的转换特性因环境、气候等运行条件而变化。因此,为提高精度,在动态信号处理以后,还需对各种缓变因素造成的系统误差进行补偿——进行静态数据处理。工程上常常在现场调试中以人工试凑的方法进行。这种人工试凑的办法,实质上是在调试时的特定运行条件下进行的一种经验拟合,通常只适合于特定的运行条件,而很难适 Dynamic track computer dynamic balance is a kind of dynamic weighing equipment that can pass through the train section by section accurately weigh the weight of the car. During operation, the train is moving, the carriage is vibrating and colliding. The weighing signal transmitted in the analog channel is changed several times by sensors, amplifiers, A / D converters and other devices. The conversion characteristics of these devices vary with operating conditions such as the environment and climate. Therefore, in order to improve the accuracy, after dynamic signal processing, systematic errors due to various slowing factors need to be compensated - for static data processing. Engineering often on-site debugging in the method of artificial test together. This artificial approach to trial and error is essentially an empirical fit under specific operating conditions during commissioning and is generally only suited to specific operating conditions and difficult to adapt
