本文概要分析了几种可能的车型鉴别方案的优缺点。详细论述了以测量车辆转向架中心距为主要依据和运用电子逻辑电路与微型计算机相结合完成车型鉴别的原理和方法。提供了实现这一原理的电子逻辑电路设计和微型计算机鉴别车型的具体方法及程序流程框图。简要介绍了车轮传感器和数车传感器的原理结构和安装情况。关于系统的检测精度及其稳定性举了实例说明。文中利用电子技术把几个互为独立的单一信号通过回路综合、逻辑门控、数字化信号输出与计算机特有的“访口”、“访内”功能有机结合的方法,对处理诸如车型鉴别一类比较繁杂问题,具有一定参考价值。
This article summarizes the advantages and disadvantages of several possible vehicle identification schemes. The principle and method of vehicle type identification based on the measurement of the vehicle center distance of the bogie and the application of electronic logic circuit and microcomputer are described in detail. Provides the realization of this principle of electronic logic circuit design and micro-computer identification of specific methods and program flow diagram. The principle structure and installation of wheel sensor and several car sensors are briefly introduced. An example is given on the detection accuracy and stability of the system. The article uses electronic technology to separate several independent signals from each other through loop synthesis, logic gating, digital signal output and computer-specific “interview”, “visit” function of the organic combination of methods such as vehicle type identification More complex issues, with some reference value.
