Wang Guo-qiang · Journal of Liaoning Technical University · 2005
In view of all kinds of current and voltage faults with motor running in coalmine system, the coalmine intelligent switchgear is designed. It can inspect current and voltage faults and give the LCD display. The structure characteristics of dot LCD MGLS19264 and the instruction system of controller HD60202U is presented. The new interface of hardware and software between MGLS19264 and PIC16F877A are designed. The method and the program flow chart of its Chinese characters display in coalmine intelligent switchgear system are also introduced.
