| 摘要: |
| 介绍了基于嵌入式Linux系统和IntelXscale网络处理器的Moxa智能通信服务器在煤矿井下6kV变电站自动化系统接入煤矿自动化系统中的应用。通过Linux串口编程技术、多线程编程技术和网络编程技术对其进行二次开发,实现了智能通信服务器的多个串口同现场不同接口、通信协议种类繁多的测控装置和智能设备的通信,收集它们的实时采样数据,同时采用Modbus/TCP协议作为智能通信服务器和煤矿调度指挥中心的通信协议,将处理后的各种现场实时信息纳入煤矿调度指挥中心,实现了井下6kV中央变电站的无人值守。由于Modbus/TCP协议具有通用性,所以该装置可与多种上位机软件监控平台建立连接。 |

| Abstract: |
| The application of Moxa intelligent communication server based on embedded Linux and Intel Xscale net-processor in connecting underground 6 kV substation automation system to coal mine integrated automation system is introduced.After secondary development using Linux serial programming technique,multi-threading technique and net programming technique,the intelligent communication server can communicate via its serial ports for collecting real-time sampling data from various measuring and control equipments adopting different interfaces and protocols.It also communicates with command center with Modbus / TCP protocol for transmitting the processed real-time information to realize unmanned 6 kV underground substation.As Modbus / TCP is open,the server can connect with different monitoring and control software platforms. |
