【摘要】 提出一种基于网络和多线程技术的热处理实时控制方式,可完成现场设备的网络控制和现场数据的实时采集.利用C++Builder 6.0开发系统的操作界面,采用RS485总线实现网络控制,在此基础上应用基于多线程的异步串行通讯技术,保证串口通信的实时性,提高系统资源的利用率.在信息的发布上,采用基于TCP/IP网络协议的Internet技术,真正实现了热处理工艺的网络监控.更多还原

【Abstract】 A real-time control mode based on networks and multithreading technology is presented in the paper.It can control field device by networks and can real-time sample field data.The system uses C++ Builder 6.0 to develop the system operation interfaces,and adopts RS-485 bus to realize netted control,on basis of these,it uses asynchronous serial communication technology based on the multithreading to ensure real time of serial communication and enhance the utilization rate of system resource.In the information promulgating,it uses internet technique based on the TCP/IP networks protocol to accomplish Network Monitoring of heat treatment technics.更多还原
