The principle and troubleshooting of the gate

Principle and structure: (1) Card reader: Through the principle of radio frequency induction, it can identify the built-in encrypted card number of the induction card. (2) Proximity card: store the user's ID number that cannot be copied and decrypted. (3) Controller: Stores inductive card permissions and card swiping records, and centrally processes all card readers upload signals, responsible for coordinating with computer communication and other data storage, and is an intelligent processing center that cooperates with management software.

Electric part structure principle: (1) Signal converter: Network and long-distance communication for all data storages. (2) Management software: centrally manage and monitor all units through a computer, and perform corresponding clock, authorization, and statistical management work (3) Power supply: Provide the power supply of the system operation power and the execution structure of the gate. (4) System principle description: The card reader reads the card information and feeds it back to the controller for information processing.

The controller judges the card authority according to the card information. If it is legal, it sends an instruction to the motor of the gate to drive the gate to act. 3.

Troubleshooting (1) The top direction indicator shows X, and it does not turn into a green arrow after swiping the card: Cause analysis: The signal output of the circuit board indicator light is abnormal or the indicator light is faulty. Solution: Method 1: Only supply power to 12v, remove other signal lines, and the red cross is on, indicating that the indicator light is good, and the green arrow is still on, indicating that the indicator light is broken. (2) There is no response when reading the card, and the door does not open: (replacement method) Cause analysis: setting problem; failure of the access control system and the main board of the movement controller Solution: 1.

Confirm whether the controller is set with two-way card swiping, long press the right button for 3 seconds to enter the control panel menu, select the access mode, press the right button to enter the gate mode selection, and select the two-way card swiping; 2. Unplug the infrared port IR3 IR2 IR1 of the black box controller, short-circuit SW1 GND left opening port or short SW2 GND right opening port; 3. If the door is short-circuited, but the door is not opened by swiping the card, it means that the controller does not receive the access control signal or the line is loose; 2.

Check whether there is a beeping sound or a beeping sound when reading the card, check whether the wiring is faulty; 3. Determine whether the card reader is faulty, replace the card reader and test it; 4. Whether the relay has a relay beating sound when swiping the card, the access control controller has a problem; you can refer to the above maintenance methods for the wing gate and swing gate 5.

The main board of the movement controller is faulty, and the replacement method is tested; 6. There is no problem with the above, the motor is faulty, and the replacement method is checked; (3) When the swing door swings, the two sides are not synchronized. It swings randomly or the opening/closing is not in place: Cause analysis: control board setting error; motherboard failure Solution: 1.

Check whether the parameters of the channel control board are normal; 2. If the parameters are normal, the control board is faulty; The swing door keeps swinging back and forth, and the passage automatically restarts repeatedly: Cause analysis: motor encoder problem Solution: Check whether it is caused by the encoder fault; 5. The swing door is loose, and the swing door can be displaced by pushing or forcibly passing it by hand: Reason analysis: National screws are loose Release method: check whether the fixing screw is loose; Pedestrian gate three roller gate Can't turn to pass after swiping the card: Cause analysis: access control system; three-roll gate solenoid valve and control board failure Solution: 1.

Check whether there is a beeping sound when reading the card, and determine whether the card reader is faulty; 2. There is no beeping sound, check whether the wiring is faulty; 3. Check if the relay has a beating sound when the card is swiped, and there is a problem with the access control controller; (replacement method) 4.

Use the in and out buttons to test the left and right solenoid valves, and push the lever by hand to see if it can be rotated; 5. Check whether the control board is faulty, and replace it; 7. Swipe the card once, you can rotate and pass multiple times: Cause Analysis: Reset Plate Failure and Spring Deformation Solution: 1.

If the reset board fails, the light on the reset board will light up when the lever is rotated under normal conditions; 2. Check whether the spring is deformed and whether the function is normal; Power-off reset function: 1. After the power is turned off, press down lightly with your hand, and then lift it up.

9. Can't power on the pole? Analysis of the reasons: 1) The drop bar is too high. After the gate is powered on, manually lift the brake bar.

The lock of the brake bar will push the bottom of the drop bar bracket up, but it cannot be pushed to the position where the electromagnet can be attracted. The rod cannot be buckled; 2) There is a deviation between the brake rod and the pressure block, and the pressure block cannot be buckled into the brake rod head. Solution: Turn on the gate and manually press the bottom of the drop rod bracket upward to make the electromagnet attract the iron block, then loosen the four screws that fix the drop rod bracket, and adjust the drop rod bracket slightly downward to a suitable position; 2 ) If there is a deviation between the brake rod and the pressure block, the three brake rods should be replaced with the installation position.

Power off without falling Analysis of the reason: The drop rod bracket is too high, so that after the electromagnet is desorbed, its bottom still cannot press the brake rod lock head to make it fall. Solution: first manually press the bottom of the drop rod bracket upward to make the electromagnet attract the iron block, then loosen the four screws that fix the drop rod bracket, and press it down (usually, it can be attached to the lock head at the brake rod). ), and finally tighten the screws and test the power off.
