目前我国铁路使用当中的电动转辙机,对其各项测试指标,特别是拉力尚无行之有效的测试方法,因此我们研制了一种用单片机控制的电动转辙机在线动态测试仪,该仪器可对使用当中的 ZD_6、ZD_7型电动转辙机进行动作电压、电流、时间、拉力和摩擦电流的测试,测试结果用 CTD-1A 型打印绘图机以曲线方式打印输出,也可以不用打印机而用显示器直接读出,测试过程不影响电动转辙机的正常工作,最多可同时测14组,打印格式如图1。
At present, the electric switch machine which is used in the railway in our country has not been tested effectively on various test indexes, especially the tensile test. Therefore, we have developed an on-line dynamic tester for the electric switch machine controlled by a single chip microcomputer. The instrument can be used in the ZD_6, ZD_7 type electric machine machine action voltage, current, time, tension and friction current test results using CTD-1A type plotter plotter print output, you can not use the printer Read directly with the monitor, the test does not affect the normal operation of the electric point machine, up to 14 groups can be measured at the same time, the print format shown in Figure 1.
