The invention discloses a method for avoiding an abnormal order in a roadside parking lot based on NB geomagnetism, and the method comprises the following steps that a vehicle owner pays fees, an order is finished, a platform stores the payment time, and a charging terminal modifies the parking space state into an idle state; a geomagnetic sensor senses a vehicle and pushes a vehicle message to the platform; after receiving the vehicle entering message, the platform pushes a parking space state updating message to a charging terminal; after receiving the berth state updating message, the charging terminal actively requests a berth list interface, modifies the corresponding berth state, and calculates the time difference between the current time and the last payment time; whether the time difference between the current time and the last payment time is within a non-evidence-obtaining time range or not is judged, if yes, countdown is displayed and an evidence-obtaining entrance is shielded, and if no, the parking state of the database is modified and evidences can be obtained. According to the invention, the technical problem that abnormal orders are caused due to the fact that whether vehicles are new vehicles or not cannot be judged in the process that vehicle owners go out and fall back and forth in a traditional NB geomagnetism-based parking lot is solved.

    本发明公开了一种基于NB地磁的路边停车场避免异常订单的方法,包括以下步骤:车主缴费,订单结束,平台存储本次缴费时间,收费终端将泊位状态修改为“空闲”;地磁感应器感应到车辆,推送入车消息给平台;平台接收到入车消息后,推送泊位状态更新消息至收费终端;收费终端收到泊位状态更新消息后,主动请求泊位列表接口,修改相应的泊位状态,并计算当前时间和上次缴费时间差;判断当前时间和上次缴费时间差是否在非取证时间范围内,若是,则显示倒计时并且屏蔽取证入口,若否,则修改数据库的泊位状态并可以取证。本发明解决了传统基于NB地磁的停车场在车主出车来回倒的过程中,无法判断是否是新车而导致异常订单的技术问题。
