无源感应线圈，安装于新能源车辆的内部，在所述新能源车辆的电量小于预设定的电量阈值或接收到用户的开启信号时，开启无源感应。其中，所述无源感应线圈为没有电源的感应结构，其不会消耗新能源车辆的电量，此外也不会受到新能源车辆的电量影响而无法工作，只要车辆的电量小于10％时，无源感应的功能可以自动直接开启，不会造成不充电时的开启，浪费电量，当然在小于10％之后无论是否行使到车位的位置，该新能源车辆的无源感应都会开启，方便感应。The passive induction coil is installed inside the new energy vehicle, and the passive induction is turned on when the electric power of the new energy vehicle is less than a preset electric power threshold or an activation signal from the user is received. Wherein, the passive induction coil is an induction structure without a power supply, which will not consume the power of the new energy vehicle, and will not be affected by the power of the new energy vehicle and cannot work, as long as the power of the vehicle is less than 10%, no power The function of source induction can be automatically turned on directly, which will not cause it to be turned on when it is not charging and waste electricity. Of course, after less than 10%, no matter whether it is driven to the parking space or not, the passive induction of the new energy vehicle will be turned on, which is convenient for induction.

地磁感应装置，安装于车位上，在感应到来自车辆的压力后的预设时间段内接收到所述无源感应线圈的无源感应时，产生感应电信号以启动该车位对应的充电桩；在感应到来自所述车辆的压力后的预设时间段内未接收到所述无源感应线圈的无源感应时，继续判断是否存在来自所述车辆的压力，在继续判断结果示出存在压力时，发出告警信息并发送启动信号至电子地锁以止挡所述车辆的移动。其中，所述地磁感应装置能够感应无源感应线圈，继而会出现电磁感应产生电信号，该电信号会启动该车为对应的充电桩，继而方便车辆的充电，车辆的压力可能不是新能源车辆，在该种情况下，会发出告警信息并发送启动信号至电子地锁以止挡所述车辆的移动，所述电子地锁会阻碍车辆的移动。其仅仅针对轮胎不针对其他部件，不会造成车辆的损坏。The geomagnetic induction device is installed on the parking space, and when the passive induction of the passive induction coil is received within a preset time period after sensing the pressure from the vehicle, an induced electric signal is generated to activate the charging pile corresponding to the parking space; When the passive induction of the passive induction coil is not received within a preset period of time after the pressure from the vehicle is sensed, continue to determine whether there is pressure from the vehicle, and the continuous determination result shows that there is pressure When , a warning message is issued and an activation signal is sent to the electronic lock to stop the movement of the vehicle. Among them, the geomagnetic induction device can induce passive induction coils, and then electromagnetic induction will generate an electrical signal, which will activate the vehicle to be a corresponding charging pile, thereby facilitating the charging of the vehicle. The pressure of the vehicle may not be a new energy vehicle. , in this case, a warning message will be issued and an activation signal will be sent to the electronic ground lock to stop the movement of the vehicle, and the electronic ground lock will hinder the movement of the vehicle.
