摘要
为提高煤矿选煤厂集中控制系统二次控制回路的安全可靠性、稳定性和灵活性,设计了一种基于QUANTUM PLC二次控制回路。分析了二次控制回路的可靠性、中间环节、日后管理与维护等方面。该系统通过在临涣选煤厂(东区)的实际运行,取得了良好的效果。
In order to improve the safety, reliability, stable, flexible of secondary control circuit in the concentrated control system of coal preparation plant, designs one secondary control circuit based on QUANTUM PLC. Analyzes the reliability, middle process, daily management and maintenance of secondary control circuit. This system gains good effect through the practical operation at east area of Linhuan coal preparation plant.
