SCATS信号机使用地磁检测器的解决方案

Solution to SCATS Signal Machine Using Geomagnetic Vehicle Detector

根据SCATS信号控制系统对环形线圈检测器占有时间输出特性,通过对地磁检测器的占有时间输出进行等效处理,可使地磁检测器的输出特性与环形线圈的输出相同或趋近,同时为方便使用,使地磁检测器的输出接口具有模拟线圈输出功能,使得其与SCATS系统连接时等同于使用环形线圈,可方便替代线圈使用。其处理方法对于其它类型车辆检测器在SCATS系统中替代环形线圈使用具有参考意义。

This paper presents a solution to replace the detecting loop with the geomagnetic vehicle detector. Based on the output characteristic of the loop‘s occupation time in Shanghai traffic control system, the solution treats the geomagnetic detector with the equivalent treatment, makes the output as the same or be similar to the loop‘s characteristic. And the both detectors have the same output interface of the solution, so then can be interchanged easily. The solution has the guiding meaning to use the other dectectors.
