随着中国经济的高速发展,私家车数量也在迅速增长。道路拥堵、泊车困难的问题也成为了制约城市进一步发展最大的阻碍,如何提高停车位的使用率以解决泊车难的情况是一个亟需解决的问题。针对这一情况,提出基于地磁传感器的智能车位管理系统的设计方法。系统的硬件由基于地磁传感器的无线数据采集节点、数据中继节点、数据集中器及上位机组成,数据采集终端采集停车位地磁场的信号;数据中继节点将接收到的数据采集终端的数据上传至数据集中器,再通过数据集中器通过串口发送至上位机,最终通过上位机对车位信息进行管理及显示。
With the rapid development of China’s economy, the number of private cars is also growing rapidly. The problem of road congestion and parking has also become the biggest obstacle to the further development of cities. How to improve the utilization rate of parking spaces to solve the problem of parking difficulties is an urgent problem to be solved. In view of this situation, the design method of intelligent parking management system based on geomagnetic sensor is proposed. The hardware of the system is composed of a wireless data acquisition node based on geomagnetic sensor, a data relay node, a data concentrator and a host computer. The data acquisition terminal collects signals of the magnetic field of the parking space. The data relay node receives the data of the data acquisition terminal Uploaded to the data concentrator, and then sent through the serial port through the data concentrator to the host computer, and finally through the host computer to manage and display parking information.
