Problems solved by technology

After a fault occurs, since the system itself does not have self-diagnosis and monitoring memory, it will be difficult to find faults
Because the system in the prior art is not designed with an anti-slip hook protection function, a hook slip accident occurred at the crane use site

Description

technical field [0001] The invention belongs to the technical field of digital electric control equipment, and more specifically, belongs to an AC voltage regulating and speed regulating device. Background technique [0002] The AC stator voltage regulation and speed regulation control system in the prior art is a mature thyristor phase crane motor control system. At present, the crane motor speed control system adopts the analog quantity AC stator voltage regulation and speed regulation control system produced by ABB Company, and the analog quantity AC stator voltage regulation and speed regulation control system produced by German Siemens Company. Their control mode adopts the analog quantity control mode, each parameter of the system is adjusted by the potentiometer, and the signal display adopts the light-emitting diode. [0003] Most of the existing analog speed control systems use a double closed-loop system composed of an external speed loop and an internal current l...
