Intelligent monitoring, protecting and controlling electric appliance device

The invention discloses an intelligent monitoring, protecting and controlling electric appliance device. By innovating a circuit principle method of controlled equipment (various pumps, transmission equipment, electric/pneumatic brakes/valves, hoists, frequency converters, soft starts, button boxes/operation columns and the like), an intelligent electric appliance device integrating local/remote operation, state acquisition, signal output and bus communication of the controlled equipment is realized. The system comprises a DI state acquisition module, an AI/AO analog quantity input/output module, a CPU processor, a DO instruction output module, a bus communication module, a display module, a storage module and a shielding layer, networking control with a far-end automatic control device can be conveniently realized, and local operation of controlled equipment and remote networking automatic control are realized. According to the invention, the circuit principle is clear under the condition that the original o
