Document Type and Number:
WIPO Patent Application WO/2024/012074
Kind Code:
A1
Abstract:
A contracting-brake control method, an electronic device and a storage medium. The contracting-brake control method comprises: after a contracting-brake release instruction is received, controlling, by means of a first contracting-brake release control policy, an output voltage of a contracting-brake power source to be reduced from a maintenance voltage to a first contracting-brake release output voltage; when it is detected that a brake shoe starts to move, controlling, by means of a second contracting-brake release control policy, the output voltage of the contracting-brake power source to be adjusted from the first contracting-brake release output voltage to a second contracting-brake release output voltage; and when it is detected that the brake shoe is in place or the speed of the brake shoe is zero, controlling the output voltage of the contracting-brake power source to be adjusted from the second contracting-brake release output voltage to zero, wherein the maintenance voltage is used for keeping the brake shoe of a contracting brake in a pull-in state, and a first contracting-brake release control time is less than a second contracting-brake release control time.
