Electronic door locks are electronic devices, so once the electronic door lock system is too complicated, it will inevitably increase the probability of system failure. If there is a problem with the electronic door lock, what should I do? Here are a few simple methods for electronic door lock repair. First, electronic lock maintenance 1. When the legal card opens the door and the green light is shining, there will be 8 short sounds of “嘀â€, and the door lock cannot be opened. The solution at this time is to replace the battery. 2. When the system identification error is red, there will be a short sound of “嘀†4, and the door cannot be opened because the system identification is wrong and the system card can be replaced. 3. When the machine is locked, the yellow light will appear. At this time, the door cannot be opened, and the door is opened by the emergency card. 4. When the electronic anti-lock yellow light is on, there will be a short sound of “嘀†2, unable to open the door, and unlock the lock card to open the door. 5. When the temporary termination occurs, the yellow light will be on, and there will be a short sound of “嘀†3, and the clear card will be cancelled. Second, the door lock maintenance precautions 1, do not use lubricants casually Some friends often like to drop some lubricity into the keyhole when the door lock is bun or tight. This way, the door lock can be smoothed, but because the oil is easy to stick, the keyhole is later. It will gradually accumulate dust and form oily putty, which will make the door lock more simple and malfunction. The correct solution: cut some pencil pieces or some candle pieces, blow them into the inside of the lock cylinder through the thin tube, and then pierce the key and repeatedly roll several times. 2, do not force the key to open the door Some time points, because of the gravity of the door leaf itself, or the margin of the door, causing the door to sink, showing the door is not locked smoothly. This time is usually very difficult to open the door with a key and lock the door. At this moment, don't force the key to avoid breaking the key and adding trouble. The exact solution: the cause should be checked first. If the door leaf sinks due to loose leaflet, loosen the loose leaf with screws. If the door frame is deformed or its cause is unrecoverable, the door frame can be opened and the lock tongue can be enlarged accordingly, so that the door lock switch door can be recovered normally and smoothly. Electronic lock principle Electronic locks, which are also based on 51 series single-chip microcomputers, with corresponding hardware circuits, complete password setting, storage, identification and display, drive electromagnetic actuators and detect their drive current values, receive alarm signals from sensors, send Data and other functions. The MCU receives the entered code and compares it with the password stored in the EEPROM. If the password is correct, the electromagnetic actuator is unlocked; if the password is incorrect, the operator is allowed to re-enter the password, up to three times; if three times If it is not correct, the MCU will alarm the intelligent monitor through the communication line. The single-chip microcomputer sends the unlocking operation and the driving current value of the electromagnetic actuator as the status information to the intelligent monitor at this time, and also sends the alarm information received from the sensor interface to the intelligent monitor as the basis of the intelligent analysis. In terms of security, it is necessary to prevent the card from being illegally copied and unlocked in an abnormal manner (such as tool dialing, smashing, sucking with a strong magnet, etc.), and the lock body should have a certain ability to resist external damage. In order to prevent the proximity of the proximity card, each sensor card is usually encrypted before it leaves the factory. Different users use different passwords. The card issuance management software is also protected by a password to prevent unauthorized persons from using the card issuing management software to illegally manufacture the card. Due to the three-lock anti-lock cylinder, when the laboratory door is closed, the anti-dial lock is pressed by the door frame, and the main lock is automatically locked, and cannot be opened or opened by the tool. In addition, the clutch mechanism driven by the motor has the function of preventing the strong magnet from being sucked, and the front lock body does not have any nails exposed on the lock body, and the tamper can be removed. Electronic lock installation First, prepare the installation tool for the door lock Tools: hammer, flat chisel, ruler, Phillips screwdriver, 4mm hexagonal screw wrench, 2mm hexagonal screw wrench. Electric drill, drill bit. Second, the difference in the direction of the door lock 1. Right (R) open door lock: The door hinge (door button) is located at the right door frame and is the right door. 2. Left (L) open door lock: The door hinge (door button) is located at the left door frame and is the left door. Third, the method of excavation lock slot * (Example: square IC card lock / K70 # large lock body) Excavation lock slot: first open the lock core slot at the appropriate height of the door: dig the lock core slot at the center of the door side; after digging, open the hole template or drawing provided by the hotel electronic lock supplier inside and outside the door as the sample opening First, open half of the door (dig into the lock core slot), and then open the hole on the other side, this operation can avoid errors. Fourth, excavate the door frame lock plate slot The hole must be opened after the door lock is installed, and the plastic box and the lock plate of the gusset plate are excavated for the opening size. Fifth, the installation of intelligent door lock door lock inspection and the elimination of common problems during the installation process 1. The door lock is installed normally. The combination of the tongue and the tongue should be popped freely. The tongue should be able to extend smoothly, and the mechanical key can open the door normally. 2. The most common problems after the door lock is installed: A, the combination of the door lock oblique tongue can not be fully extended, the solution is: (1) Adjust the lock lever (upper, lower, left, and right), and the oblique tongue and the square tongue are facing each other, so that the oblique tongue can smoothly expand and contract. (2) Look at whether the side trim panel is not installed properly and hold the oblique tongue. (3) When the door opening is opened, the movable part of the combined oblique tongue is not too narrow on both sides of the lock cylinder groove, and the combined oblique tongue is stuck. Solution: The lock cylinder of the lock cylinder groove should be widened in the movable part of the tongue. Through the electronic lock maintenance and lock protection measures described above, we believe that we can prevent and respond to the failure of electronic locks at an early stage. At the same time, the protection of the lock should be in place, and our lock can be used for a long time.
