Automatic parking lot management is the safe and effective management of parking lot using highly automated electromechanical equipment. As a result of minimizing manual participation, personnel costs and losses caused by human error are minimized, and the safety and use efficiency of the entire parking lot are greatly improved.

Parking lots can be divided into two categories: “internal parking lots” and “public parking lots” according to their use objects. The internal parking lot is mainly for the fixed car owners of the parking lot and the units, companies and individuals who lease parking spaces for a long time. Generally, it is mostly used in the underground garages of various units’ own parking lots, supporting parking lots of apartments and residential districts, office buildings and office buildings, long-term parking lot rental garages and garden villa communities, etc. The characteristics of this kind of parking lot are that the users are fixed, the use of external vehicles is prohibited, the users have a long time to use the facilities, and the safety requirements of the parking lot management are strict. High reliability and processing speed requirements. Public parking lots mainly provide services for temporary individual passengers, and are divided into “fee” and “free”. Public parking lots are commonly found in large public places, such as stations, airports, stadiums, shopping malls and other places. The users of parking facilities are usually temporary one-time users, with a large number and short time. The parking lot management system is required to have low operating costs, easy to use, solid and reliable equipment, and can meet commercial processing requirements such as tolling. Some large public parking lots often have multiple entrances and exits, and the computers at the entrances and exits and toll booths are also required to be connected to each other.

1 Business needs

Generally speaking, users who use parking lots to park are divided into two categories:

The first type of users are “fixed users”, which are characterized by: there are fixed parking spaces in the parking lot, and they drive vehicles in and out every day0 ~ NSecond-rate. In the existing parking lot management systems, most of them use “smart cards (short-distance type)” to manage the entry and exit of the parking lot by “fixed users”.In other words, every time the user enters and exits the parking lot, the driver must stop near the “card reader” and be close (less than1rice) Show the smart card, so that the “card reader” can read the card information, drive the “block lever” up, and realize the “release” operation.

When the vehicle passes through the turnstile, the driver has to complete a series of actions, such as: “slow down”, “stop”, “open the window”, “swipe the card”, “wait for the lever to lift”, “drive”, etc. Obviously , This is an inefficient management method that can complete access management functions.

For a long time, parking lot operators hope to find an efficient way to manage vehicles driven by “fixed users” without parking. Such a problem-solving method can satisfy both the driver and the parking lot manager.

The second category of users is “temporary users”, which is characterized by: there are no fixed parking spaces in the parking lot, and customers who drive in and out of the parking lot when necessary to achieve temporary parking. Such users must park and receive management when entering and exiting the parking lot.

In short, we must solve the problem of “parking and brushing off the card” under normal conditions..

Shanghai Xiupai company based on its ownRFIDThe mastery of technology and a full understanding of the vehicle management business process willRFIDThe technology is applied to the intelligent vehicle management process, thus solving the traditional vehicle release method of parking and swiping cards, greatly improving the efficiency of vehicle release, and ensuring smooth traffic at the entrance and exit of the parking lot. Through correct design and installation, vehicles can pass without stopping on multiple lanes at the same time without interfering with each other.

1.1 Solution diagram

In our solution, there are mainly the following key technologies: electronic tags (long-distance cards), long-distance readers, lane controllers and other key equipment.

Just put the Showpad long-distance tag with the vehicle/The personnel are closely integrated, and the management system can effectively and accurately control the vehicles entering and leaving the unit in a large range./Personnel information is collected, recorded, uploaded and processed as required. The background computer recognizes the attributes of the vehicle based on the uploaded information, drives the gates to open correctly, and ensures that the access control system has efficient release capabilities to achieve “pass without stopping.”

Figure 1 System schematic diagram

1.1.1 For vehicles/Personnel access management

The installation method is very simple, as long as the reader is fixed to the appropriate position of the channel, for example: on the wall or bracket. The reader and the background management system (software) are connected through a standard interface, which includes:RS232,RS485, Wigan.The electronic tag is carried by the student as he(she)’S identity.Perform logical judgments in computer software to determine whether students are entering or leaving, and the corresponding time can be recorded when people enter or leave the door (assuming we install separately at the entranceA,BTwo reading heads,ANear the gate,BInward10mLeft and right position, whenAprior toBWhen we read the card information, we can judge it as entering, whenBprior toARead the card information, it is judged as out) This can also be used as the unit’s attendance, automatically generate the employee’s attendance sheet, and simplify internal management.

When employees need to go out, they must get the approval of the leader. If they are allowed to go out, they can be registered and confirmed in the computer software. Then when the staff goes out of the gate, the guard room can quickly learn that they are out illegally or legally, if they are not approved If you go out privately, you can stop it, which can prevent some employees from going out privately and improve management efficiency.

In the scheme, the front-endRFIDThe equipment can form the smallest unit of work, work independently, and can be embedded in the existing management system as a subsystem, working together, no matter which way, it can complete the monitoring and management of the channel.

The most basic functions of the system include personnel card issuance, door area settings, access rights, time control, real-time monitoring, record query and report printing, etc. The system host has single-door controller, two-door controller, four-door controller and multi-door controller for selection. In addition, access control data can also be used as raw data for other applications.

2. Internal management of the enterprise

In the enterprise, in order to strengthen the management of employees, we can also install several readers where necessary to simplify the management of employees within the enterprise

First of all, it can be used as a library card for employees in the library management, or other places where they need to show their certificates.

Secondly, readers can be installed at the entrance of the office building to confirm that employees enter/Out of the factory time

Finally, readers can be installed in other occasions where monitoring is needed, and employees can record their entry at any time./When leaving such places, strengthen the safety management of the enterprise.

1.2 Identification schematic

vehicle/The core technology of automatic personnel management is the automatic identification and automatic discrimination of vehicles. The schematic diagram is as follows:

1.1 Solution system composition

vehicle/Automatic personnel management equipment can be divided into: vehicles/Automatic personnel identification subsystem, security monitoring subsystem, etc. Usually includes a central control computer, automatic identification device (Rfid), temporary card issuance and inspection device, car stop, surveillance camera, controllable reminder, etc.

The control center of the parking lot automatic management system is the central control computer. Responsible for the coordination and management of the entire system, including software and hardware parameter control, information exchange and analysis, command release, etc. The system is generally managed online, integrating management, security, statistics and business reports. It can work independently to form a unit management system, or it can be connected with other systems to integrate into a larger automatic control system.

2 Features of the technical solution

The features of the technical solutions provided by Shanghai Showpad are very prominent, which are specifically manifested in:

1. Long distance.The effective reading distance between the reader and the card is0~80Meters, this distance is suitable for most parking environments; this distance is also the technical basis for “passing customs without stopping”;

2. Circular polarization antenna. The design of the receiving antenna of the reading head adopts a circularly polarized antenna, and there is no direction requirement for the card placement;

3. High speed.The moving speed of the car card is0~200 km / h When the time, the reading head can correctly identify the card signal;

4. Long time.Electronic tags can work continuously6~8Years, maintenance-free during the period. This reduces maintenance costs for users and management, and directly improves economic benefits.
