Control system of intelligent lock driving motor

Abstract

The invention discloses a control system of an intelligent lock driving motor. The control system comprises a CPU module, a driving module, a touch key module, a power supply module and a switch detection module, the CPU module is connected with the driving module, the touch key module and the switch detection module, and the power supply module supplies power to each module; the CPU module comprises a chip U2, and the model of the chip U2 is PIC16F1827. The control system has the following advantages that locked-rotor is controlled by detecting the running state (whether the motor rotates ornot) of the motor instead of detecting the current, the working current only needs to be 200-500 mA according to the resistance of the lock body, and the motor is in a full-power working state all thetime before running in place.

Description

technical field [0001] The invention relates to a control system for an intelligent lock driving motor, which belongs to the technical field of electronic control. Background technique [0002] The emergence of fully automatic locks has greatly improved the intelligence of door locks, especially when installing fully automatic smart locks, there is no need to replace the lock body, it has a wide range of adaptability, and is easy to operate, so it is welcomed by consumers, so it has become The new darling of the smart lock industry. [0003] However, judging from the use of fully automatic smart locks purchased by consumers at present, the prospect is not optimistic. Due to many small problems, high failure rate, and great complaints from consumers, many large-scale smart lock companies are not optimistic about this high-end smart lock. Products are daunting. [0004] There is a design defect in the existing fully automatic intelligent lock: whether the indentation or pop-...

AI Technical Summary

Problems solved by technology

[0004] There is a design defect in the existing fully automatic intelligent lock: whether the indentation or pop-up of the lock body and the bolt is in place is completely completed by detecting whether the drive motor is blocked, that is to say, every time the lock is opened and closed, the motor is blocked. turn is complete

[0009] 1. The high current causes the motor to heat up rapidly, and the winding is burned

[0010] 2. The long-term action of overload torque on the lock body will distort and deform the transmission mechanism until it is damaged

[0011] Due to the wide variety of lock bodies, the angle of rotation of the lock cylinder required for the lock tongue to retract and pop out is also different. Even the lock bodies of the same manufacturer and model have different angles due to manufacturing errors, which makes it impossible to artificially set the locking position. , which has also become a defect that the existing fully automatic smart lock cannot overcome
