本发明的基于磁场传感器的车辆停放状态探测装置,包括电源、探测器、数据处理与传输模块,其电源管理模块分别连接处理器和磁场传感器,处理器分别与磁场传感器和PC机串口通信工具双向数据连接,PC机串口通信工具与上位机双向无线连接。该探测装置利用磁场传感器在有外部磁场干扰源的影响下,各个方向上的磁场数据发生比较大幅度的变化,依据变化的幅度情况判断该区域是否有车辆停放,不容易受温度变化及风雪天气干扰、性能可靠、安装方便、价格经济,可以运用于大型停车场的智能化管理系统中。
The device for detecting the parking state of a vehicle based on the magnetic field sensor comprises a power supply, a detector, a data processing and transmission module, wherein the power management module is respectively connected with the processor and the magnetic field sensor; the processor is respectively bidirectionally with the magnetic field sensor and the PC serial port communication tool in bidirectional Data connection, PC serial communication tools and PC two-way wireless connection. The detection device uses the magnetic field sensor in the presence of external magnetic interference under the influence of the magnetic field data in all directions more substantial changes occur according to the changing range of the situation to determine whether there is parking in the area is not susceptible to temperature changes and snow blizzard Weather interference, reliable performance, easy installation, affordable, can be used in large parking lot intelligent management system.
