动态电子轨道衡中判别电路的改造设计

An Improved Design of the Judge Circuit of the Dynamic Eletronic Track Scale

本文设计了一种逻辑电路 ,它接收从传感器经自行设计的前向通道传送来的信号 ,用以判别列车行驶方向和上衡时间。该判别电路可取代传统的用行程开关或光电开关作为测量装置的控制电路 ,大大降低了系统的故障率 ,有效地提高了轨道衡称重的可靠性。

The new type of judge circuit invented in the paper can tell the direction and exact arrival on the coming train on the track scale by analyzing the signal sent by the sensors.It can replace the traditional measuring devices with the result of reducing the failure rate and raising the reliability of the track scale.
