Electric control lock is a mechanical lock device controlled by relays. At present, a variety of different structures have been formed, including electric plug -in locks (anode locks), cathode locks (electric lock port), magnetic locks, electronic control locks, etc.Essence
Electrical control lock principle
The terminal of the electrical control lock is actually an electromagnet, which controls a simple mechanical device for the door switch.However, the actions of electromagnets are moved through a series of instructions.When it cannot be controlled, first measure the voltage of the electromagnet, and at the same time enter the switch door instruction (some are electromagnetic cards, some input passwords) to see if the voltage has changed.The failure is the electromagnetic control part, and the electromagnetic control part should be repaired or replaced, otherwise the control part of the failure.The control part is relatively complicated. It has two parts: hardware and software to control, and some are also connected to the computer interface, which can conduct personnel entering and exit query statistics.The general control output voltage is controlled by relay control.First of all, see if there is a sound and combination of relays. If not, it can measure whether the voltage and driving device of the relay control interface can be measured. If it is intact, it can further measure the working voltage of the integrated circuit.Generally, software failure, which can only be contacted with developers.If the relay has a suction sound, and the voltage of the relay is normal, it is the line disconnection of the lines of the relay or sent to the electrical control part.
Electric control lock installation
First of all, many cars are raised by the original car. If you install it, it is very simple. The following points are required:
1. Put the main motor on the door of the drivers door. Each other two -line motor (three door left) is installed, and all the motors are fixed;
2. Connect the motor motor with the trolley or lifting button on the original car (unlocked handle) to ensure that it can be operated freely;
3. Smoise each motor wire, the plug is firmly and arrange the wiring beam, and you cannot miss it outside;
4. Fix the center control box under the side instrument platform of the drivers driver, and connect a plug;
5. If the iron general anti -theft device is brown and white wire to the anti -theft host, this is the switch signal.Finally, by operating the main driver motor, other motors can follow the action.To say maintenance, this does not need to be maintained.
Electric control lock cable diagram
The door opening button is connected to the access control controller. When swiping the card or the button, the relay movement on the access control controller.The positive electrode of the access control power supply first receives the NC of the relay on the access control controller, the+12V of the COM connecting the electric lock on the controller, and the GND of the electric lock GND.
