二、自动门PLC控制系统设计的思路和方法 ，应该怎样写。
你用的是哪个PLC控制的。这个其实是比较简单的，关键你要理清整个的思路，搞清楚控制要求。用梯形图来编写程序很简单。首先知道实现的要求是什么？要知道有哪些东西连锁，互锁，有哪些保护。然后根据理解写程序。方法只能你自己写程序慢慢体会怎么编程的问题。如果用三菱的或者西门子的都可以仿真实现效果。
三、快来拿高分了，给我翻译好了就有 。
Mine drainage control system design - electrode-level automatic control system design (plc control -4 × 100kw)
Abstract
In the process of coal mine production safety, drainage control system plays a very important role, is indispensable to the mine operating equipment. But coal mine drainage systems are used relay control, the pump stopped and opened by the choice of switching to complete, also can not automatically open under water pumps stopped, seriously affecting underground drainage pumping station at the management level and the improvement of economic efficiency . In response to this status quo, develop a programme of drainage systems to optimize the drainage system and reduce investment in equipment. Through the displacement of a reasonable match, the pump is the single work or whether the joint work, the drainage system in the state of maximum efficiency, minimize the net energy consumption, through the realization of PLC control underground mine drainage system automation.
In recent years, with computer-controlled technology is developing rapidly, especially on microprocessors as the core of the programmable logic controller (PLC) control in industrial control process widely used in factory automation also on a new level. Programmable Logic Controller (PLC) from the 1980s as a development of the emerging industrial controller, automatic control, computer and communications technology of combining the product, is a devoted to industrial production process control equipment at the scene. Replace the use of PLC relay control, and mine drainage pump control, drainage control system will enable more secure.
Mine drainage in the use of automatic control system PLC control, the system can store the water level by detecting water and other parameters, control pumps and timely start work in rotation standby pump, rational management of four water pumps running. The operating system is reliable and easy to operate, the high degree of automation, pumps and save operating costs.
Key words: automatic control, drainage systems, PLC control
