Design of automatic induction parking lock based on RFID

1. Overview of parking lock

Nowadays, parking spaces are becoming increasingly tight. How to prevent private parking spaces from being seized by others is a headache. A new type of parking lock in the city of Rizha not only effectively solves this problem, but also plays an anti-theft role on the vehicle, which is very popular with car owners. Special parking lock can effectively and politely prevent other vehicles from occupying special parking spaces: when the car arrives near the parking space, open the parking lock to park the car in the parking space; when the car leaves, lock the parking space lock to prevent other vehicles from occupying the parking space; After the car is parked in the parking space, the parking space lock is locked, and at the same time, it can play the role of anti-theft of the vehicle. At the same time increase the parking lock management, the parking lot can enhance the parking lot and facilitate the management of the parking lot.

According to the control method, the parking lock can be divided into manual parking lock, remote control parking lock and automatic induction parking lock. The manual parking lock can be opened or closed by a dedicated key; the remote control parking lock can be controlled by the handheld wireless remote control within a range of 20 meters; the automatic parking lock is divided into wireless radio frequency induction and Bluetooth Auto-sensing, when the owner's car is within 20 meters of the parking lock, the parking lock will automatically unlock and land, and when the owner's car is 20 meters away, the parking lock will automatically raise and lock.

2. Wireless automatic induction parking lock

The wireless automatic induction parking lock is a wireless automatic induction parking lock which is the first domestic product launched in cooperation with the well-known domestic parking lock company. The parking lock automatically senses the position of the vehicle and realizes the functions of “car-to-lock to open, car-to-lock to close”, completely free of human operation. It also avoids the phenomenon that the owner forgets to raise the parking lock when leaving, ensuring foolproof. While we enjoy the ease brought by high technology, we also avoid the high cost of using Bluetooth induction.

1. Working principle:

Auto-sensing parking lock is a car using wireless radio frequency identification technology, referred to as RFID. The user is equipped with an electronic label card. When the vehicle arrives at the parking space, the receiving end of the parking lock will automatically recognize the ID number emitted from the electronic label card. The parking lock automatically descends through information processing. The vehicle enters the parking space at this time. When the car leaves If the ID number of the electronic tag card cannot be received, the parking lock will automatically go up, which can effectively prevent other vehicles from occupying the parking space.

2. Product features

A. Function:

The auto-sensing parking lock can effectively and politely prevent other vehicles from occupying dedicated parking spaces. When the master car arrives near the parking space, the parking lock automatically falls and the car can be parked in the parking space; when the master car leaves, the parking lock automatically rises to prevent other vehicles from occupying the parking space.

Protection level: IP65, anti-spray;

Working power supply: DC6V;

Power usage time: 30-50 days

Automatic sensing distance: 20-30 meters;

Duration of rise and fall: 6 seconds;

4. How to install and use the product

A. After unpacking, connect and fix the battery plug with the control board plug; about 12 seconds, the parking lock will automatically rise or fall (depending on the location of the electronic label); the parking lock should not be installed in a low-lying place or a place with water.

B. According to the specific situation (depending on the size of the parking space), it is advisable not to prevent other vehicles from reversing after installation. Choose the installation location and drill a 14mm bottom hole in the floor at the corresponding hole of the parking lock base.

C. Install M10mm expansion screws in the ground, put on the parking lock, then tighten the nuts, spray the screws with black oil, and the installation is complete;

5. Instructions for use

A. After installation, it can be put into normal use immediately.

B. The electronic label needs to be hoisted on the rearview mirror in the car with a wire.

C. When there is no car in the parking space, the parking lock should be in the up position.

D. When the car arrives within the effective receiving range near the parking space, it should wait for the parking lock to descend and drop to the lowest position before parking the car in the parking space.

6. Daily maintenance and maintenance

A. The structure is simple and the failure rate is low, which is a major feature of the parking lock.

B. When the parking lock movement slows down and is significantly lower than before, it means that the battery should be charged (low voltage alarm).

C. Maintain the sanitation around the parking lock. There should be no particulate impurities in the base; add oil to the moving parts of the parking lock every six months.

7. Matters needing attention

A. When the parking lock is going up or down, there must be no foreign objects or external forces hindering its movement.

B. The time for the parking lock to rise and fall is 4-6 seconds. When the battery voltage drops, the time will be slightly delayed. The maximum or minimum position has not been reached in 10 seconds. At this time, it means that the battery is to be charged.

C. When cleaning the parking lock, do not directly flush the interior of the parking lock with water.

D. The battery is best to be charged regularly, which can extend the service life of the battery for more than 4 years (30-50 days to charge once, depending on the frequency of use).

3. Introduction to other types of parking locks

The characteristic of this parking lock is that the wireless remote control has replaced manual labor and has become very easy to use.

3. Automatic induction parking lock

At present, there are two ways of inductive parking locks: wireless automatic inductive parking lock and Bluetooth automatic inductive parking lock. When the owner's car approaches the parking lock, the parking lock automatically falls; when the owner's car moves away from the parking lock, the parking lock automatically raises.

The characteristics of the automatic induction parking lock are: the fully automatic lifting mode completely replaces the manual operation, improves the grade, and makes life more relaxed and happy.
