Chapter 1: Introduction to the non-stop management system
Many engineering business friends are familiar with the access control system, but are not very familiar with the parking lot system, and feel that the parking lot management system is very complicated. Based on a win-win concept, Yisheng Tianhong has developed a simple parking lot management system similar to an access control system. This system has simple structure, convenient construction, short construction period and low maintenance difficulty. It is convenient for more engineering business friends to get involved in the parking lot project, and this system can also be used to transform the previous parking lot. The system is mainly suitable for parking systems with fixed users, such as (government agencies, military management areas, institutions, business units, high-end communities, etc.)
This system is actually an enlarged access control system. First of all, we can get familiar with the composition of the access control system. The access control system generally has the following components:
Access Controller
The core part of the access control system, equivalent to the computer’s CPU, is responsible for the processing and storage of the input and output information of the entire system, control and so on.
Card reader
A device that reads the data (biometric information) in the card.
card
The key to open the door. The cardholder’s personal photo can be printed on the card, and the door card badge can be combined into one.
other devices
Exit button: Click on the device to open the door, suitable for situations where there is no restriction on going out.
Door sensor: used to detect the safety/switch status of the door, etc.
Power supply: the power supply equipment of the entire system.

Chapter 2: Non-stop traffic-an overview of the intelligent parking lot management system (single lane mixed in and mixed out)
Non-stop traffic-smart parking lot management system (single lane mixed in and out) best suitable place recommendation
Non-stop traffic-intelligent parking lot management system (single-lane mixed in and mixed out) is mainly suitable for fixed user parking system, (in government agencies, enterprises, institutions, high-end residential communities and other internal vehicles dedicated parking lot)
There is no foreign vehicle entering, and the parking demand that only provides services for the unit’s vehicle is the best recommended use
The delineation of its scope of use depends on the function of the system itself.
Non-stop traffic-intelligent parking lot management system (single lane mixed in and mixed out) hardware function overview
As far as a pure hardware system is concerned, this system fully embodies the automatic operation characteristics of the system. And provides a variety of operational guarantees.
The system adopts the Wiegand transmission method, which is simple and universal, and can make full use of the existing network conditions without special communication lines, thereby saving engineering costs and operating costs. At the same time, the card number can be downloaded according to different card readers to solve the control of vehicle access to different entrances and exits. For example: A (port) card reader downloads card number A, and B (port) card reader downloads card numbers A and B. Then we can control different channels through the card reader to control different vehicles entering and exiting different channels. In other words, for port B, both A-card and B-card vehicles can enter and exit, while A-port only allows A card to enter and exit.
Non-stop traffic-intelligent parking lot management system (single lane mixed in and out) working mode (different card readers control different vehicles in and out)
Install a long-distance radio frequency card in the vehicle, and register the radio frequency card to the control board connected to the 2.4G card reader. The card reader will identify the registered card or the unregistered card to control the vehicle’s access to different channels. When the vehicle enters the approach entrance, the first sense of ground is triggered and the 2.4G card reader is triggered to start reading the card. After reading the radio frequency card installed in the road vehicle, the 2.4G card reader will upload the card number to the control board, and the control board will judge the card. Judge whether the card is a registered card, that is, it is a valid card; when the judgement is successful, the barrier will be automatically controlled to open and release. When the vehicle passes the second ground sense under the barrier of the barrier, the vehicle detector detects the disappearance of the second ground sense signal and issues an instruction to close the barrier. The barriers are automatically opened and closed. When reading an unregistered card, the barrier will not automatically lift the bar, that is, you cannot enter or exit this entrance. Thus, the problem of different card readers controlling different vehicles entering and exiting the same entrance and exit is achieved.
Chapter 3: Non-stop traffic-introduction to the relative advantages and disadvantages of the parking lot management system (single lane mixed in and out)
Non-stop traffic-introduction to the relative advantages of the intelligent parking lot management system (single lane mixed in and mixed out)
Advantage 1: High degree of automation, large cost savings in manpower and material resources, and low overall cost.
Advantage 2: Compared with the manual control of entrance and exit guards, a considerable degree of automation is realized, which reduces the difficulty and workload of entrance and exit guards, and reduces the incidence of human accidents.
Advantage 3: Compared with the parking lot system that confirms the identity by swiping the card at close range, it has realized a considerable degree of intelligence, eliminating the cumbersome process of parking-opening the window-swiping card-starting traffic of the unit (system) vehicle; instead, it is No need
Direct access to the entrance and exit when parking.
Advantage 4: No complicated system software is required, and it can be run offline (without the computer control program).
Non-stop traffic-introduction to the lack of functions of the parking lot management system (simplified version)
Non-stop traffic-the intelligent parking lot management system (single lane mixed in and out) only judges whether the car is a vehicle of the unit (system). If it is judged, it will open the gate, and if it is judged, it will be ignored. (Judgment The basis is whether the two radio frequency cards installed in the car are the registration cards of the current system), so relative to the “full version of non-stop traffic-parking lot management system”, the following functions are missing:
Missing 1: When non-unit (system) vehicles need to pass through the entrance and exit, manual processing is required;
Missing 2: The judgment condition of this system is single, which can only be identified by the “RF card” installed in the car. (Our company’s “No-Stop Pass-Parking Lot Management System (Standard Version)” can realize the functions of Missing 1, Missing 2. )
Chapter 4: System configuration structure and working logic
First of all, please see the following diagram of mixing in and out of single lane:
This system requires the following configuration:
3 ground induction coils, A, B, C
1 barrier
Two long-distance card readers, antenna No. 1 facing outwards, antenna No. 2 facing inwards
Several electronic tags for vehicles
Management logic:
When the vehicle is moving from the outside to the inside
After the vehicle is pressed to the ground sense of A, the card reader is triggered to read the card;
Antenna No. 1 will read the electronic tag of this vehicle and transmit the signal to the barrier;
The barrier is open;
The barrier will automatically close after the vehicle passes B ground sense;
The vehicle is pressed to C ground again, and the card reading operation is started. If the card is read, the system will automatically find whether the target card number is in or out of the field. After it is judged to be any operation of entering or leaving the field, the software is incorrect. The card number is recorded; if the card is not read, the management system will not respond;
The vehicle enters the venue smoothly
When the vehicle moves from the inside to the outside
After the vehicle is pressed to C ground sense, the card reader is triggered to read the card;
Antenna No. 2 will read the electronic tag of this car and transmit the signal to the barrier;
The barrier is open;
The barrier will automatically close after the vehicle passes B ground sense;
When the vehicle is pressed to ground A, the management system will make judgments and card reading operations the same as when entering;
The vehicle went out smoothly
Exception handling:
On both sides of the aisle, convex mirrors are set in the areas outside the ground sense of A and C to prevent two or more vehicles from advancing and retreating in the aisle.
The main purpose of this system is to identify fixed users with 2.4G vehicles, to facilitate the access of fixed users, without considering the management of temporary vehicles.
The composition of the system:
Three ground sense coils, A, B, C ground sense, will be connected to the two vehicle detectors, and then connected to the controller (integrated with the card reader circuit board)
1 barrier, high-speed barrier, with triple anti-smashing function: induction detection anti-smashing + torque anti-smashing + infrared detection anti-smashing, and the rod itself has anti-smashing treatment
Antenna No. 1 is facing outwards, Antenna No. 2 is facing inwards
Chapter 5: System hardware equipment performance advantages
The performance advantages of long-distance card reader controller
The 2.4G long-distance card reader has a long recognition distance, which can reach 5-150 meters. Different radio frequency cards can be selected according to different needs. It has strong anti-interference ability and moderate cost. It represents the development direction of long-distance identification and control in the future. Many local governments regard it as the focus of future development in the field of identification. And data transmission can be carried out through a variety of communication interfaces (RS232, RS485, Wiegand).
2.4G long-distance card readers can be widely used in intelligent parking lot management systems, highway non-stop toll collection systems, container intelligent dispatch systems, intelligent traffic dispatch systems, vehicle violations, anti-counterfeiting inspection systems, commodity anti-counterfeiting, anti-theft, and integrated logistics applications , Open access control, electronic identity recognition, item tracking, asset management, library management, vehicle access control, non-stop automatic toll collection (ETC), personnel access control, electronic anti-counterfeiting, conveyor belt cargo sorting, pallet packaging workstation data collection And coding, factory work-in-process management, warehouse logistics management, retail logistics center management, production automation management, coal mine and underground management, etc.
In this system, as a device to determine whether to open the gate, its core performance requirements are stability and sensitivity, and it maintains good coordination with other devices in the system.

The position of the active card in the car is more flexible, and it can be placed in any position in the car.
Chapter 6: System Construction and Installation Instructions
The construction and installation of the system are relatively simple. The main body of construction and installation is the installation of barriers, 2.4G antenna poles and ground induction coils.The following preparations need to be done before construction and installation
Survey and survey of construction and installation site to determine the construction plan
Parking lot construction is mainly divided into ground parking lot construction and basement parking lot construction. Relatively speaking, ground construction is relatively simple. It is convenient to adjust the installation position of each device. For underground parking lots, the equipment should be placed on a relatively horizontal ground as far as possible (installed vertically on the horizontal plane), and the barriers need to be folded-rod barriers. The placement of barriers and card readers is directly related to the convenience of users. Once the location of the pipeline is determined, changing the location will cause a lot of trouble for the construction. Therefore, for engineers who do not have much engineering experience in this area, install the barriers and card readers first. When it is in place, simulate the user, and work with Party A’s personnel to see if the positioning is appropriate, and finally confirm the installation plan.
Note: For the parking lot system with the entrance and exit in the same position, the width of the two lanes should be fully considered when determining the installation position of the barrier. Generally, the width of the lane should be greater than or equal to 2.5m and less than or equal to 4m. The width of the road occupied by the barrier should be fully considered when determining the installation location of the barrier. Thereby comprehensively design the installation location of the barrier.
After the site survey is completed, it is necessary to give specific construction drawings based on the survey situation, and strictly indicate the construction location of each equipment and the line connection facilities between each other.
Description of construction rules:
System connection line laying construction
Before the construction of the system, it is necessary to plan the connection lines between the system’s mutual equipment. After confirmation, the line laying construction shall be carried out according to the construction drawings.
The pipeline laying is relatively simple. Before laying the pipeline, clarify the signal attributes, signal flow and power supply of each device according to the schematic diagram of the parking lot system and the pipeline diagram; the signal line and the 220V power line should be routed through the pipe separately, and the strong current is weak. The pipes cannot be laid together. For power cords, wires of different voltage levels and current levels cannot be threaded through the same iron pipe at the same time.
Line construction requirements:
A: Strong current and weak current lines should be laid separately
B: Laying lines on the ground requires pipe-through operation (the line is passed inside the iron pipe)
Ground induction coil construction and installation
The construction and installation of the ground induction coil can be regarded as the most important part of the parking lot system installation. Before the installation starts, it is necessary to draw the accurate position of the ground induction coil on the ground according to the construction drawings. The size requirement of the ground induction coil is: 2m (length) × 0.8m (width).String
The number of laps is 6-8.
The cutting size of the groove for the ground induction coil is: width 0.5-1cm and depth: 3-4cm
After the ground-sensing coil placement slot is cut, extend the ground-sensing coil dedicated wire (anti-corrosion silver wire) clockwise around the slot for 6-8 turns, and extend the coil extension wire to the vehicle in the barrier cabinet after double-crossing In the detector.
After the system is finally debugged and the ground sensing coil is working normally, you can fill the ground sensing coil placement slot with cement or asphalt (or marble glue) to complete the installation of the ground sensing coil
Note: The installation method of the ground induction coil can refer to our company’s “Ground induction coil production manual”
The installation distance between two ground-sensing coils in the same lane is 350cm (the distance between two coils adjacent to each other). If the actual site environment cannot reach 350cm, it can be adjusted according to the site environment.
Barrier installation
According to the construction drawings, after confirming the installation position of the barrier, the barrier can be fixed by the expansion bolt worn by the barrier.
Note: If there are conditions or requirements, a waterproof and anti-collision safety island (installation base) with a height of 10-20cm can be cast, and the pipeline is embedded in the middle of the base of the barrier.
