Entry Control Design of Parking Management System

With the development of economy and the continuous improvement of living standards, the ownership of family vehicles and social vehicles is rapidly increasing. Due to the limited space on the ground, the contradiction between parking spaces in parking lots becomes more and more prominent, and the importance of parking management will be increasingly appreciated. The core of its technology is the automatic monitoring, identification and automatic management of vehicles.

If you want to manage a parking lot and maximize utilization, you must start with the entrance control of the parking lot. The entrance to the early parking lot was generally controlled by a manager and a railing. However, when the number of vehicles in the parking lot increases, the scale increases, and the security requirements increase, the original management can no longer meet the needs of users. It is particularly important to intelligently manage parking lots and install necessary equipment to control them at the entrance.

The core of the entrance control is the entrance control machine. The difference between the mainstream entry control machines in the market should mainly be reflected in the identification method used: automatic take-out of thermal paper/magnetic ticket, automatic access of proximity card, manual induction card, automatic coinage Type etc.

Entry Control System Configuration and Description

The entrance control of the big hand control brand car park management system includes the basic configuration: entrance ticket/card reader control, barriers, and vehicle detectors; it can also expand the parking guidance display screen, voice prompt operating system, voice intercom, avoid red and green Signal lights, image contrast, license plate recognition, long-distance parking card reader system, etc.

2. How it works
Sensing monthly card vehicle management Each month card vehicle, ie the internal vehicle, holds a sensory month card. When entering the venue, the owner of the vehicle approaches the entrance control machine located at the entrance of the parking lot. The LCD screen on the control panel displays the Chinese operating instructions. The owner of the vehicle controls the reader to read the card in the reading area of ​​the controller according to the instructions. If the card is valid, the entrance barrier lifts and releases the vehicle; if the card fails, the LCD screen displays a failure prompt and the entrance barrier does not move. After entering the market with a valid card, the entrance barrier will automatically fall.

The usage time, usage times and types of each monthly card can be freely set by the management software, and all vehicle reading and writing card in and out events (including invalid card reading) will be recorded by the management software event recorder to facilitate post-event statistics and verification.

The entrance control system can also perform the following practical functions when the monthly vehicles enter and leave the parking lot:

"One Card One Vehicle" function: One month card can only park one car. When the card is used by a certain car, other vehicles cannot use this card to avoid the occurrence of one card with multiple usages;
Read card exit recovery function: After the valid month card reads the card, the barrier lifts, and the card reader vehicle does not pass through. After the vehicle exits for 10 seconds, the raised barrier will automatically fall, avoiding that the barrier will always be lifted. State of affairs;
Anti-smashing car function: If there is a car below the track bar in the process of dropping the bar, the bar will automatically lift to prevent picking up the car. After the vehicle passes completely, the barrier arm will fall again;
Offline function: When the computer malfunctions or shuts down, the monthly card vehicle can read and leave the card as usual.

Paper ticket temporary vehicle billing

When an outside temporary vehicle enters the parking lot, the owner of the vehicle approaches the entrance control machine located at the entrance of the parking lot. The LCD screen on the control panel displays the Chinese operating instructions. The owner presses the ticket collection button on the control machine and takes the ticket. Lift rod to release the vehicle. The parking ticket is a one-time use thermal paper ticket. The black-white entry time and barcode information is printed on the ticket surface. It is intuitive and effective. The owner can judge the parking time on his own. After the ticket pick-up vehicle enters the yard, the entrance barrier will automatically fall.

Entrance control major equipment function parameters

1. PIC-910KF Entrance Ticket Pickup/Reader Controller

The PIC-910KF entrance controller is the entrance control core of the high-performance, high-stability parking fee management system with an embedded intelligent control unit. It provides effective, cost-effective and stable advanced automatic control functions while effectively controlling costs while being highly competitive. The price of power meets the needs of customers. The PIC-910KF entrance controller is used in a parking management system that has a monthly card vehicle self-service approach and a temporary vehicle self-service approach. It is installed along with other entrance equipment on a safety island on the side of the parking entrance passageway to monitor the entrance equipment and provide self-service for the approach of the vehicle.

2. PAB-20 High Speed ​​Digital Gate

PAB-20 series high-speed gates are embedded intelligent control units. They are designed with special motors and advanced mechanical structures. They are suitable for car stop equipments in all kinds of car park management systems. It originated from European product design style and Germany's latest mechanical structure design technology. The work is more stable, reliable, and the appearance is stable. It meets the customer's demand with a very high cost performance. The PAB-20 series high-speed gates are mainly installed at the entrance/exit of each parking lot, or installed at the toll gate/entry entrance of the expressway, which restricts the entry and exit of vehicles.

Entry Control Technology Application

1. Card ticket combination replaces traditional automatic card delivery

The materials used in the entrance control management vehicles should mainly reflect the identification methods used. However, it is also one of the users' requirements to save costs and reflect the concept of environmental protection. At present, large-scale parking lots in China mainly use smart card identification technologies (such as non-contact IC cards and non-contact electronic tags), which is different from some countries in Europe and America. At present, many countries in Europe and the United States still use paper tickets as a vehicle entry and exit credentials.

2. CAN fieldbus replaces traditional RS485

The CAN bus is a serial data communication protocol developed by German company BOSCH from the early 1980s to solve the data exchange between numerous control and test instruments in modern automobiles. It is a multi-master bus and the communication medium can be double Stranded wire, coaxial cable or fiber optics.
