车辆检测器-智能路考

<a name="OLE_LINK11">M73</a>磁场检测器,是通过磁阻传感器对磁场的检测来判断车辆是否按照规定路线行驶。其磁场感应部分采用HoneyWell生产的磁阻传感器,配合高速单片机来完成对磁场的采集及判断。产品响应速度可以达到1kHz。可以开机自动校准环境磁场。能够判磁场的极性。有简单的逻辑电平输出和RS232串行数字信号输出两种信息方式。可以修改磁场报警门限,及报警延时。 <div class="Section1"> <a name="OLE_LINK10"></a> </div> <span lang="EN-US" style="font-size:10.5pt;
