Abstract

The invention discloses an electromagnetic brake control device and method. The device comprises a control core unit, a clock unit, a photoelectric conversion input unit, a photoelectric conversion output unit and an electromagnetic brake control interface unit, The control core unit is used for receiving a brake input signal and a clock signal and sending a brake output signal; the photoelectricconversion input unit is used for sending the brake input signal to the control core unit; the photoelectric conversion output unit is used for sending the brake output signal to the electromagnetic brake control interface unit; the electromagnetic brake control interface unit is used for driving an electromagnetic brake to attract. The system adopts a control mode of high-pressure suction and low-pressure holding, the high-pressure suction ensures that the electromagnetic brake has larger locking torque at the suction moment, the low-pressure holding can effectively reduce the heating aging of the electromagnetic brake caused by long-time high-pressure suction, and the service life of the electromagnetic brake is greatly prolonged.

Description

technical field [0001] The present invention relates to the technical field of electromagnetic brakes, and more particularly, to an electromagnetic brake control device and method. Background technique [0002] In the current self-service gates at border inspection ports, in order to prevent the gates from being maliciously pushed open, electromagnetic brakes are basically installed on the motors that drive the gates. Once someone pushes the door, the brake is immediately engaged to lock the gate. Most of the existing electromagnetic brake control methods use fixed voltage control, which is prone to insufficient locking torque due to insufficient voltage at the moment of brake pull-in, causing the gate to be easily pushed open. close, it is easy to cause the brake to heat up and burn out. In addition, the existing electromagnetic brake control devices basically do not have a temperature detection function. If the brake is engaged for a long time and the temperature is high...
