摘要
提出了一种基于RS485总线,以软件方式实现并适合于分布式监控的网络通信方法,实现了互锁联动门禁系统的网络化通信,并结合多线程机制以提高监控软件的实时性.实践表明这种方案是有效实用的,能够满足分布式监控中的网络通信和实时性要求,并具有较高的性价比.
A new network communication method based on RS485 bus is proposed and realized by way of software, which is suitable for distributed system, Multithread technology is adopted to improve the real - time of the monitoring and control management system. It is proved through practices that this scheme is effective and practi- cal to meet distributed system network communication and real - time requirements, with a high performance price ratio.
