三轴数字磁传感器在停车场管理中的应用

摘要

Need for modernization and smart parking management, Honeywel three-axis digital magnetic sensor is designed to the magnetic detection node for parking. By gathering geomagnetic size and the thresholds for distinguishing algorithm, it can detect whether the Parking space is used. Through processing the test data and selecting a reasonable threshold that makes detection accuracy greater than 98%. In addition, through using low-power design, Two batteries makes the detector continues for 2 years.%　　针对停车场现代化管理和智能监控的需要，采用霍尼韦尔三轴数字磁传感器设计停车位地磁探测节点，通过采集车位地磁大小并通过阈值的判别算法可以检测停车位上是否有车辆停放。通过对测试数据的分析和处理，选择合理的阈值能使探测精度达到大于98%，此外探测节点采用低功耗设计，两节电池可以使探测器持续工作2年。
