在户外进行停车场车位检测容易受到不同外界因素的干扰，从而造成不必要的车位信息错误，给停车场的管理和停车用户带来诸多不便。针对这类户外停车场车位检测的实际要求以及对相关车位检测技术的研究，提出以基于巨磁电阻的车位检测技术作为核心检测技术，即汽车在停放或离开车位时使得地磁场与巨磁电阻之间磁场关系发生的变化来判断车位上车辆的变化，并且配套的设计了基于巨磁电阻检测的硬件系统和软件系统，分别用于停车位的车位检测和车位的显示，同时通过对巨磁电阻灵敏度的调节来更加灵活和准确地进行检测。试验结果表明，相比于其他车位检测技术该车位检测技术拥有更高精度和更强稳定性。

In the outdoor parking lot ,parking space detector can be easily interfered by various external factors ,re-sulting in unnecessary errors in parking space detection and incorrect parking management decisions as well as user delay . According to the actual outdoor parking space detection needs and the related detection technology requirement ,this paper presents an approach based on the giant magnetoresistance detection technology ,which achieves vehicle detection by de-tecting the magnetic field change in giant magnetoresistance before and after a vehicle has left .The design is based on gi-ant magnetoresistance detection hardware and software systems ,which provide data for information display and giant magnetoresistance sensitivity adjustment .The test results show that ,compared with other detection techniques ,this parking space detection technology provides higher precision with consistency .
