基于DeviceNet现场总线的矿井“信、集、闭”系统实现

The design of a signal-centralization-interlocking system for a shaft station based on DeviceNet

介绍了基于DeviceNet现场总线的OMRON公司SRM1 PLC在井下“信号、集中、闭塞”系统中的应用。该系统工作可靠、运行稳定、抗干扰性强且组网成本较低、硬件布线简便、系统扩展性强,易于实现矿井网络化控制和管理。

This paper presents the design and implementation of a signal-centralization-interlocking system applicable to a shaft station which uses the SRM1 PLC as a main controller. The system hardware structure and the control way are described in the paper. It has many advantages, such as the reliability, strong anti-jamming ability, good system expansibility, etc.
