小型车位传感器及停车场无线传感网技术研究
|
摘要
无线组网、低成本和小型化已成为车位探测器的发展方向。本文研究了安装在停车位便携式可拆除小型一体化地感线圈车位探测器组成无线传感网,实时采集停车场各个车位的车辆信息,通过短距离无线通讯模块发送给无线中继器,中继器将收集的信息反馈给中央控制器,从而构建停车场无线传感网。该方案研究的无线组网小型地感线圈传感器可探测底盘高度为0. 1～0. 3 m车辆,车位检测响应时间小于5 s,地感线圈尺寸0. 2 m×0. 3 m。
The direction of development of the parking detector will be of wireless networking,low cost and miniaturization.This paper studies the parking detector,which are portable,removable,small integrated,also called ground inductive coil parking sensor,make up wireless sensor networks. Real-time acquisition of the vehicle information will send to wireless repeater through short-range wireless communication module. Then information is fed back to the central controller. So above is the operation process of the wireless sensor networks. The sensor of the thesis can detect chassis height of 0. 1 ～ 0.3 meters vehicles under the conditions that the response time need to less than 5 seconds,and the size of ground inductive coil need to be 0. 2 m × 0. 3 m.
