The problem of single-chip microcomputer control of Electromagnetic Lock 1. The pins from the Electromagnetic Lock MCU cannot directly control the lock. Usually the method of controlling the unlocking is to use a relay or a power surge to energize and open the lock control. 2. The unlocking time cannot be longer than 1 second. The voltage and current from the pins of the single-chip microcomputer cannot meet the requirements of the lock. Therefore, it is necessary to directly design the peripheral circuit to power on and control the unlocking, and the single-chip microcomputer controls the unlocking time. 3. Use the pins of the single chip microcomputer to unlock the lock. Its disadvantage is that it is easy to burn out the single chip microcomputer, and the voltage and current of the pins of the single chip microcomputer cannot be pushed to unlock the lock.
Electric Control Lock For Logistics Cabinet Product Description 1. Working mode: It adopts the working mode of closing the door (power off) to lock, and powering on (3.3V) to trigger the unlocking at an instant, and the light is on when the door is opened; 2. Emergency unlocking: There are emergency unlocking methods in all directions of the lock body, and the lock can be unlocked without damaging the cabinet in an emergency; 3. A mechanical key can be installed, and it can also be unlocked externally with a mechanical key, and the operation is simple and convenient; 4.
