摘要
设计的网络型机动车停车场控制管理系统是以单片机为执行核心,以计算机软件为管理核心,提出一种监控自动化、信息管理自动化网络解决方案。通过计算机网络技术和RS 485工业总线的应用,车场规模可以无限制扩展。在门禁控制机中加入信息存储电路,有效地避免了通信堵塞现象,同时信息存电路又可作为临时的上位机热备份机,即使上位机短时间失效停机,系统的监控运作依然正常。这样的小冗余度设计实现了上下位机互补、软硬件互补的运行,保证了系统稳定无差错运行。
The designed networking motor vehicle park system takes single chip computer as execution core, software as monitor core. It supplies the solution for automatic monitoring and information manage network. Using computer network technology and RS 485 industrial bus, the scale of park can be extended without limit. In the access control machine adds infor- mation storage circuit effectively avoid the phenomenon of communication jam, and the database of up- level computer is back- uped by collecting information from down - level computer controlling doors, thus ensuring the stability of system operation without error. Such design with minimum redundancy achieves the upper and lower machine complement each other, comple- mentary software and hardware to run,ensuring the stability of the system error- free run.
