Intelligent motor system for intelligent lock and motor control method

Abstract

The invention relates to an intelligent motor system for an intelligent lock. The intelligent motor system includes a body, wherein the body is provided with a gear set driven by a motor, the gear setincludes a worm connected with a rotation shaft of the motor, a transmission gear in transmission mesh with the worm, and an output gear in rotation mesh with the transmission gear, the output gear is connected with the rotation shaft, the body is further provided with a circuit board, the circuit board is provided with a Hall sensor, the gear set is provided with a magnetic block, and the magnetic block passes by the Hall sensor periodically when the gear set is in operation. The intelligent motor system is advantaged in that in the rotation process of the gear, the magnetic block continuously passes by the Hall sensor periodically, periodic magnetic field pulses are recorded by the Hall sensor, the quantity is further calculated, the actual pulse quantity is compared with the quantity set in the system, when the actual pulse quantity reaches or is close to the preset quantity, before stall occurrence, the motor is made to stop, and thereby influence on the service life of the motorcaused by the overlarge current due to stall is avoided.

Description

technical field [0001] The invention belongs to the technical field of intelligent lock equipment, and specifically relates to an intelligent motor system used in an intelligent lock, and at the same time, the invention also relates to a motor control method of the motor system. Background technique [0002] With the development of the economy and the progress of science and technology, ordinary mechanical door locks can no longer meet the needs of many people, and the application of smart locks is becoming more and more extensive. Commonly used smart door locks include fingerprint locks, IC card swipe locks, password locks, iris locks, face recognition locks, etc. For most household door locks, the lock cylinder transmission device is still controlled by a motor, such as the forward rotation of the motor to drive the rotating shaft to rotate to make the lock cylinder extend, and the reverse rotation of the motor to drive the rotating shaft to rotate in the reverse direction...

AI Technical Summary

Problems solved by technology

[0003] At present, in conventional smart locks, the motor cannot accurately determine the current position of the motor during work. It can only be judged that the motor is in place by blocking the rotor. The loss of electricity and the loss of the motor itself will also break down the power supply and control circuit due to excessive current, which will have a greater impact on the life of the equipment
