- 摘要:
- 针对大中型城市停车场泊车困难、车位使用效率不高和入口交通拥挤等问题,设计并研制一种无线智能泊车引导系统。系统由基于激光测距传感器的数据终端、数据路由器、数据协调器和上位计算机组成,数据终端实现对所有车位是否占用信息的检测和无线发送; 数据路由器接收这些车位信息后无线转发给数据协调器; 数据协调器通过串口把接收到的数据上传到上位计算机; 上位机管理平台对车位数据作解析和统一处理,由大屏幕显示器进行发布和管理。测试结果表明该系统测距精度≤3%,通信距离≤400 m,检测准确率为99.6%,验证了设计的正确性和有效性。
- Abstract:
- In view of the problems such as difficult parking, inefficient use of parking spaces and heavy traffic at the entrance in parking of lots of large and medium-sized cities, a wireless intelligent parking space guidance system is designed and developed in this paper. This system consists of a data terminal based on laser ranging sensors, a data router, a data coordinator and an upper computer. The data terminal realizes the detection and wireless transmission of the occupation information of all the parking spaces, the data router receives this information and then wirelessly transmits it to the data coordinator, and the data coordinator uploads the received data to the upper computer through the serial port. The parking space data is analyzed and uniformly processed by the management platform of the upper computer, and is released and managed by a large-screen display device. The test results of the system show that the ranging accuracy of the system is less than 3%, the communication distance is less than 400 m, and the detection accuracy is 99.6%, which verify the correctness and effectiveness of the design.
