摘要
为保证地面原煤运输系统安全、有效、可靠地工作,需要对系统进行控制和保护。提出一套基于S7-300 PLC的地面原煤运输自动控制系统。将PLC在控制方面的优点有效的结合到本系统中,以提高整个系统的安全性和可靠性。PLC作为该系统的核心,通过传感器对工作现场数据进行采集,然后再通过以太网传输给上位机,实现实时监控。
In order to ensure the ground raw coal transport system safely, effectively and reliable to work, which need to control and protection system.This designing presents an automatic control system based on S7-300 PLC. In order to improve the security and reliability of the whole system,combined the advantages of PLC in the control of effective to this system. Through the sensor was carried out on the field data acquisition, and then transferred to the PC via Ethernet, realize real-time monitoring,PLC is the core of the system.
