嵌入式停车场管理系统

Parking lot management system based on embedded design

为改进基于PC的传统停车场管理系统工作于恶劣的环境中稳定性较差的问题,提出了一种基于嵌入式的停车场管理系统的设计方案。该方案结合MVC模式及QT/E技术实现了友好的嵌入式终端的界面交互;考虑到大型停车场多进多出的工作模式,使用心跳信号解决网络通信中常见的网络链接不稳定的状况;利用基于线程技术的数据采集有效保障数据采集的实时性和可靠性。经大量测试及实际使用证明,这种新型的嵌入式停车场管理系统,在工作稳定性上有大幅提高的同时使得停车场的成本也有所下降。

To improve poor stability problem of the traditional PC-based parking management system working in harsh environment, a parking lot management system based on embedded design was proposed in this paper. In this design, being combined with MVC patterns and QT/E techniques to achieve a friendly interactive interface for embedded devices; taking into account the multiple-in and multiple-out work mode of large parking lot, using the heartbeat signal to reinforce unstable link which is a common problem in network communication; making use of data collection based on multithreading technology, the real-time and reliability of data acquisition were effectively guaranteed. By a great number of tests and practicalities, it is certificated that this new parking management system is stable and the cost is decreased.
