随着铁路和高速公路的迅速发展,交通管理部门希望研究出一种安全可靠的交通管理系统来保证物资的快速运输。 以前,为满足上述需要,一般采取用电磁感应目标识别装置。由于这种装置是利用电磁感应耦合原理工作的,在列车或货车上要装设响应装置(车上传感器),它不允许与铁制部件紧密安装在一起,限制条件很多。尤其是装在地面上钢轨之间的询问装置(地上传感器)
With the rapid development of railways and highways, the traffic management department hopes to develop a safe and reliable traffic management system to ensure the rapid transportation of materials. In the past, to meet the above needs, the general use of electromagnetic induction target recognition device. Since this device is based on the principle of electromagnetic induction coupling, a response device (on-board sensor) is to be installed on a train or truck, and it is not allowed to be closely packed with the iron parts, and the restriction conditions are many. In particular, installed in the ground between the rails of the interrogation device (above ground sensor)
