Abstract
The invention relates to an intelligent digital controller for a mine rectifier cabinet, and belongs to a rectifier cabinet controller. The intelligent digital controller is adopted to primarily solve the technical problems that existing controllers are inaccurate in digital displaying, poor in current control precision, complicated in structure, inconvenient to maintain and the like. The technical scheme mainly includes that a single chip computer is used as a digital controlling core, and digital circuits are concise and strong in anti-interference capacity. Collected analog voltage and current are converted into digital values by the single chip computer; the voltage and current are displayed by a common anode nixie tube, and are compared with preset voltage and current in a program; if the voltage exceeds the presser voltage, a overvoltage alarm signal is output by the single chip computer to remind operators to be cautious of the output voltage of rectifier devices; if output current exceeds the preset current, an overcurrent alarm signal is output by the single chip computer, and power source of the rectifier devices can be cut off so as to protect electric devices. The intelligent digital controller is mainly used for the mine rectifier cabinet.
