可编程逻辑控制器(PLC)技术具有较高可靠性、较强扩展性、较广适用性及简单使用等优点,在各领域均得到了广泛应用。其中PLC在矿井提升机设备控制系统中的应用,代替了原来的继电器—接触器控制,实现了原来电子线路不能完成的各种功能,在某种程度上提高了控制系统的稳定性,保证提升机的安全平稳运行,是现代工业企业理想的自动化控制装置。
Programmable logic controller (PLC) technology has the advantages of high reliability, strong scalability, wide applicability and simple usage, and has been widely used in various fields. Which PLC in mine hoist equipment control system, instead of the original relay - contactor control to achieve the original electronic circuit can not be completed a variety of functions, to some extent, improve the stability of the control system to ensure that enhance Safe and stable operation of the machine, the ideal industrial automation and control devices.
