摘要:

针对大型停车场中车位检测装置的能耗问题和可靠性问题,提出了一种主动磁场停车位检测新装置；使用永磁体建立主动磁场,通过设计磁路,使得停车位上车辆的存在会改变通过传感器的磁力线的闭合路径,选用低功耗的磁传感器检测通过其本身的磁通量,以输出的磁感应强度值的大小为依据判断停车位上是否停有车辆；计算与仿真结果表明:该车位检测装置可行且检测结果可靠；其克服了地磁场的干扰,解决了能耗问题,成本低,可靠性高,有利于提高大型停车场的管理质量。

Abstract:

An active field parking detection device was presented to the problem of energy consumption and reliability of large parking spaces in detecting device. It used permanent magnets to establish active magnetic field,the existence of parking space vehicle could change the closed magnetic field lines through sensor by designing the magnetic circuit,it chose the magnetic sensor with low power consumption to detect through its magnetic flux,and based on the magnetic induction intensity output value to judge whether the stopped vehicle parking. The calculation results and simulation results show that:the parking stall detection device is feasible and its test result is reliable. The device overcomes the geomagnetic disturbances and solves the energy consumption problem,which has the advantages of low cost and high reliability. It is helpful to improve the management quality of the large parking lot.
