4.详细说明在图1中给出了一个车轮滑转控制系统10。这个系统的微处理机12能够通过输入端21a、b,22a、b、c、d 接收多个输入信号。这些信号分别表示铁路车辆的运行方式,也就是说,是驱动运行方式还是制动运行方式。任可一种适当的装置都可产生制动运行方式信号,例如,制动开关24当车辆制动时闭合。同样,驱动运行方式开关23可以产生驱动运行方式信号。铁路车辆(未示出)有一对转向架 X、
4. Detailed Description A wheel slip control system 10 is shown in FIG. The microprocessor 12 of this system is capable of receiving a plurality of input signals via inputs 21a, b, 22a, b, c, d. These signals respectively indicate the operating mode of the railway vehicle, that is to say, whether it is a drive mode or a brake mode. Any suitable means may generate a brake operating mode signal, for example, the brake switch 24 is closed when the vehicle is braked. Likewise, the drive mode switch 23 can generate a drive mode signal. A railway car (not shown) has a pair of bogies X,
