Installation and maintenance of electronic lock and its principle

First, prepare the installation tool for the door lock.

Tools: hammer, chisel, ruler, Phillips screwdriver, 4mm Allen key, 2mm Allen key. Electric drill, drill bit.

Second, identify the direction of the door lock.

1, right (r) door lock: The door hinge (door knob) located on the right door frame is the right door lock.

2. Left (L) door lock: The door hinge (door button) located on the left door frame is the left door lock. |

Three. Method of digging lock groove * (Example: square IC card lock /K70# lock body)

Excavating the lock slot: opening the lock cylinder slot at an appropriate height of the door: excavating the lock cylinder slot at the center of the door side; After digging, take the template or drawing inside and outside the door provided by the hotel electronic lock supplier as the sample to open the hole. Open the door halfway from one side (dig into the lock cylinder slot), and then open the hole from the other side. This operation can avoid mistakes.

Fourth, the excavation of the lock plate groove of the door frame must be opened after the door lock is installed, and the plastic box and lock plate of the lock plate are used as the opening size of the excavation.

Verb (abbreviation of verb) Intelligent door lock installation inspection and troubleshooting of common problems during installation.

1, the door lock is installed normally. The combination of oblique tongue and oblique tongue should pop up freely, and the square tongue should be able to extend out of the machine smoothly. The mechanical key can open the door normally.

2. The most common problems after door lock installation:

First, the combination door lock tongue can not be fully extended, the solution is:

(1) Adjust the lock lever (up, down, left and right) towards the oblique tongue and square tongue, so that the oblique tongue can extend and retract smoothly.

(2) Check whether the side trim panel is installed irregularly, and hold the oblique tongue against it.

(3) When opening the door hole, the movable part of the combined inclined tongue should not be too narrow on both sides of the lock cylinder groove, so that the combined inclined tongue is stuck;

Solution: The movable part of the lock cylinder combination oblique tongue of the lock cylinder groove should be widened.

Matters needing attention and principles of electronic lock maintenance

I. Maintenance of Electronic Lock

1. When the green light of the legal card door opening alarm flashes, there will be a short "beep" sound, and the door lock cannot be opened. The solution at this time is to replace the battery.

2. System identification error. When the red light is on, there will be a short sound of "beep" 4. The door cannot be opened because of system identification error. Just replace the system card.

3. When the lock is locked mechanically, the yellow light will light up. At this time, the door can't be opened, so you can open the door intelligently through the emergency card.

4. When the electronic anti-lock yellow light is on, there will be a short "beep" sound, and the door cannot be opened. Cancel the lock of the room lock card and you can open the door.

When the card is temporarily terminated, a yellow light will light up and there will be a short "beep" sound. Just cancel the termination of the reset card.

Second, the door lock maintenance matters needing attention

1, don't use lubricant casually.

Some friends usually like to drop some lubricating oil into the lock hole when the lock is rough or locked, so that the lock will be smooth immediately. But because oil is easy to stick to dust, dust will simply accumulate in the keyhole in the future, forming a greasy child, which will make the lock simpler and more faults.

Accurate solution: cut some pencil scraps or some candle scraps, blow them into the lock core through a thin tube, then poke the key in and roll it a few times.

Don't twist the key to open the door.

Sometimes, due to the gravity of the door leaf itself or the loose leaf of the door, the door leaf sinks, showing the appearance that the door is not locked or opened smoothly. At this time, it is usually very difficult to open and lock the door with a key. At this time, don't twist the key hard, so as not to break the key and add trouble.

Accurate solution: check the reason first. If the door leaf sinks due to loose loose loose leaves, the loose loose leaves should be fixed firmly with screws. If the door frame is deformed or cannot be restored due to its reasons, we can start with the door frame and enlarge the lock tongue accordingly, so that the door lock can be restored normally and smoothly.

Third, the principle of electronic lock

The electronic lock is also based on the 5 1 series single chip microcomputer, and cooperates with the corresponding hardware circuit to complete the functions of password setting, storage, identification and display, driving the electromagnetic actuator and detecting its driving current value, receiving the alarm signal from the sensor and sending data.

The MCU receives the typed code and compares it with the password stored in EEPROM. If the password is correct, it will drive the electromagnetic actuator to unlock. If the password is incorrect, the operator is allowed to re-enter the password for up to three times; If it is incorrect for three consecutive times, the single chip microcomputer will alarm the intelligent monitor through the communication line. The single-chip microcomputer sends the driving current value of the electromagnetic actuator and each unlocking operation as state information to the intelligent monitor, and also sends the alarm information received from the sensor interface to the intelligent monitor as the basis for intelligent analysis.

In terms of security, it is necessary to prevent the sensor card from being illegally copied and unlocked in an abnormal way (such as tool dialing, prying, attracting with a strong magnet, etc.). ), and the lock body should have a certain ability to resist external damage. In order to prevent the sensor card from being illegally copied, each sensor card is usually encrypted before leaving the factory, and different users use different passwords. The card issuing management software also has password protection to prevent unauthorized personnel from using the card issuing management software to illegally make cards. Due to the adoption of the three-lock anti-dialing lock core, when the laboratory door is closed, the anti-dialing lock is pressed by the door frame, and the main lock is automatically locked, so it cannot be opened or pried open with tools. In addition, the motor-driven clutch mechanism has the function of preventing strong magnets from attracting, and there are no exposed nails on the front lock body of the door lock, which can be disassembled and smashed.
