使用可编程控制器改造提升机电控系统

Reform on the lifter electrical control system by using programmable controller

使用可编程控制器来改造现有提升机电控系统 ,已在许多矿井使用 ,但与国外相比较还有相当差距 ,特别是象磁放大器等一些基本电器仍要使用 ,这些电器完全可以在原有可编程控制器基础上附加特殊控制单元来代替其功能 ,达到国外先进国家的水平。就这方面的问题提出自己的见解。

The programmable controller used to reform the present lifter electricial control system in mine for years,but comparing with adroad still has great shortcomings, especiallys,the magnetic enlarger etc.basic electric instruments still used,these electric instruments completely should be replaced by the original programmable controller added additional special control unit to instead of its function and attain the level of abroad advanced countries.This paper puts forward its own views.
