As a landmark project for Xiamen to build an important central city on the west bank of the Taiwan Strait, the second phase of the Xiamen Software Park project is a national software park, with a total land area of 1.063 square kilometers, a total construction area of 1.6364 million square meters, a floor area ratio of 1.367, and a building density of 21.5%. With a green area rate of 55% and 7,116 parking spaces, it is one of the largest software parks in the country. The project consists of 11 plots, and the building types include R&D buildings, hotels, administrative buildings, property buildings, leisure clubs, restaurants, hotel-style apartments, etc.
General design description of the project 1. Project overview The second phase of Xiamen Software Park has four functional areas and can accommodate 50,000 people. The scale of the project is 51 in and 51 out parking equipment, including: the main entrance on the ground is 6 sets of networked equipment (6 in and 6 out), the underground garage of the administrative building is 2 sets of networked equipment (2 in and 2 out), and the single building underground The entrance and exit of the parking lot are 43 sets of independent equipment (43 in and 43 out), which is currently the largest parking lot management system project in the country.
Engineering design goals The investment and construction of the parking lot of the second phase of the software park should be able to achieve the following goals:
Convenient, fast, intelligent, and automated vehicle entry and exit; classified control and parking management of fixed monthly rental vehicles and temporary hourly rental vehicles; safe and convenient parking and storage of vehicles, and well-documented abnormalities; reasonable, accurate, and rigorous parking charges To avoid man-made cheating; the park management is highly efficient, humane, intelligent, and detailed in the classification of permissions; the most important thing is that the cost is economical and affordable, which can greatly reduce the operation and management costs and reduce the loss caused by lost or wrong cars , At the same time, the computer billing is accurate, reasonable and strict, which can bring huge social and economic benefits to the park; 3. Design principles The system design follows:
(1) The principle of safety (2) The principle of practicability (3) The principle of stability (4) The principle of scalability (5) The principle of easy maintenance In combination with the above requirements, we conducted an in-depth analysis of the management of vehicle entrances and exits in different locations, and the management of vehicles with different needs in the same location, and made the following designs:
1. Park entrance and exit vehicle management system design We learned that the park entrance and exit vehicle management is mainly for the construction of vehicles entering and exiting the three entrances and exits of the park east and exit, the south entrance and exit of the park, and the west entrance and exit of the park.
Since the above three main entrances and exits have a large number of vehicles coming in and out every day, there are frequent vehicles, there are fixed vehicles, and there are temporary foreign vehicles, vehicle management modes are different, etc…. Therefore, the system design of the main entrance and exit of the park focuses on the following aspects:
a. The rationalization of the main entrance and exit lanes.
We plan the main entrances and exits of each park as a four-lane management, that is, one entry and one exit for fixed vehicles and one entry and one exit for temporary vehicles, a total of two entries and two exits. In this way, the separation of fixed lanes from temporary lanes mainly has the following points to facilitate consideration:
(1) The vehicle card reading method is different, and the traffic speed will be increased after separate settings. We issue long-distance vehicle-mounted cards or IC monthly cards to fixed vehicles, so that fixed vehicles only need to be identified and read the card to confirm the release; temporary vehicles are automatically issued with temporary cards or EZ-Tong cards, and the card is paid when they leave the venue. This separates the two The speed of vehicle traffic has increased, and the traffic has become smoother.
(2) The management methods are different, the staff on duty are easy to work, and the speed of vehicle traffic is accelerated. For fixed vehicle management, we generally charge monthly, quarterly, and annual fees at a fixed time, while temporary vehicles implement immediate payment and deduction. Therefore, on-duty personnel basically do not need to deal with the passage of fixed vehicles, and automatically confirm the passage; for temporary vehicles, it is required. Receiving cards, charging fees, and setting up image comparison and confirmation as needed, can be released. After the passages are separated, only temporary vehicles need to be handled, which makes the work easier and the traffic speed is greatly accelerated.
(3) The data is processed separately, and the system runs more stably, which also speeds up vehicle traffic.
Since vehicles in fixed lanes mainly use long-distance non-stop automatic card reading or IC card reading, and temporary lanes mainly use automatic temporary card issuance or reading yitong card, and there are payment, image information, etc., so the two data The processing is different. After the respective dedicated channels are opened, the data processing on both sides is faster, the system operation is more stable, and the vehicle traffic speed is also smoother.
b. The automation and intelligence of the system configuration function.
According to the requirements, we configure the equipment at the entrance and exit of the park as follows:
(1) The equipment configuration of the fixed vehicle import and export system is: barriers, entrance and exit control machines, remote card reading systems, IC card reading systems, Chinese electronic display screens, voice systems and other equipment, of which the remote card reading system is used in Xiamen Municipal fixed vehicles (with Xiamen Road and Bridge on-board electronic tags) are used for in and out, IC card reading system is used for non-Xiamen City fixed vehicles (without Xiamen Road and Bridge on-board electronic tags) for in and out of use. When a fixed vehicle enters and exits, it can automatically open the gate and release it after the system recognizes and confirms it through a long-distance automatic card reading or reading an IC monthly card.
(2) The equipment configuration of the temporary vehicle import and export system is: barriers, entrance and exit control machine, IC card reading system, automatic card exit system, Chinese electronic display, voice system, management computer, system software and other equipment, and should be equipped with graphics Like the contrast function. When a temporary vehicle enters the field, the system will automatically issue a temporary card through the automatic card issuing mechanism. If a user has a yitong card, the card can also be read directly. When the vehicle leaves the field, the temporary card is handed over to the staff on duty, the fee is paid, deducted, and the gate is released after confirmation by the system.
(3) At the exit of each park, it is configured as a guard post on duty. There are 2 system workstations (computers) in the guard post, which are respectively used to connect the fixed lane and temporary lane parking lot controllers, and are equipped with parking lot charging software and metering devices. , UPS power supply, small ticket printer and all related accessories. When the temporary car leaves the field, the fee is paid at the exit booth, and the images are compared and confirmed to be released. All data information is uploaded to the management center through the system workstation to realize system information processing.
c. The front end of the system is supplemented by security management, and the combination of man and machine ensures the convenience of vehicle entry and exit and the safety of data management. Our management of fixed vehicles generally charges monthly, quarterly, and annual fees at a fixed time, while temporary vehicles implement immediate payment and deduction. Therefore, the staff on duty basically do not need to deal with the passage of fixed vehicles, and the passage can be automatically confirmed; for temporary vehicles, the The personnel on duty receive card, system billing, and charge, and set up image comparison and confirmation as required before release. The man-machine integrated management ensures smooth vehicle entry and exit, and data management security.
d. Computer networking, unified management, hierarchical authority, and data exchange with the main control center to ensure the information and accuracy of data processing. We set the management center of the system in 6-5# intelligent control center, and configure the system management server, system management software, IC card/vehicle electronic label issuing equipment, report printer and other equipment. Through the network management data exchange between the main control center and the workstations of each import and export, the informatization of data processing is realized.
R&D building garage and apartment building garage entrance and exit vehicle management system design R&D building and apartment building garage entrance and exit vehicle management is relatively simple, mainly for fixed vehicles management, temporary vehicles can not enter the underground garage, according to the needs of our design as follows:
(1) The R&D building is planned to be a one-in-one-out vehicle management system (except for the underground garage of Building 9-3#), and independent construction does not carry out networking.
(2) Building 9-3# is equipped with 2 sets of one-in-one-out vehicle management systems, and the two systems are locally connected to a computer for management, and are not connected to the park entrance and exit vehicle management system.
(3) Each entrance and exit configuration: barrier gates, entrance and exit control machine, IC card reading system, Chinese electronic display screen and other equipment.
Administrative complex building (6-4#) garage entrance and exit vehicle management system design According to the demand, we learned that 6-4# building is an administrative complex building, and the garage management system of this building is required to be independently managed by 6-4# weak current management center, mainly It mainly manages fixed vehicles in this area. Temporary vehicles cannot enter the underground garage. The specific design is as follows:
(1) Equipment configuration: equipped with barriers at the entrance and exit of the garage, entrance and exit control machine, IC card reading system, Chinese electronic display screen and other equipment.
(2) Set up an independent management system in 6-4# weak current management center, equipped with a management computer, management software, card issuer and other equipment.
(3) The main function of this independent system is: data recording and report statistics for vehicles entering and exiting the area of the administrative complex, effective management of fixed vehicles, and restricting temporary vehicles from entering the underground garage.
Solutions to System Technical Difficulties Regarding the following technical difficulties involved in the design of the software park system
1. The entrance and exit of the park use long-distance card reading technology to achieve automatic card reading The identification and judgment of the contact-type remote user card realizes the solution of automatic induction recognition when the vehicle is moving, and the entry and exit of the card reading operation without swinging the window. In the system application in this industry, we will use RFID non-contact radio frequency vehicle identification remote card and card reader equipment in accordance with the requirements of the bidding document.
It is suitable for the entry and exit of Xiamen fixed vehicles (with Xiamen road and bridge vehicle-mounted electronic tags) at the three main entrances and exits of the park.
2. The long-distance card reader is compatible with the Xiamen Luqiao vehicle electronic tag. Regarding the remote card reader, we are fully compatible with the Xiamen Luqiao vehicle electronic tag, and its technical parameters, technical characteristics and implementation principles are the same. The cutting-edge technological innovation products of the company fully meet the habits of users and the needs of the Chinese people. The utilization rate of RFID radio frequency reader recognition technology in the world is as high as 78%. The hardware of the remote card reader device has a standard RS232 communication method. , The card reading distance is 3-8M, the card reading time is ≤0.2 seconds, and the electromagnetic compatibility of the equipment is in full compliance with the GB/T17626 series compatibility standards.
3. IC card management and park card system to achieve seamless integration. In response to the requirements of the bid, this parking lot intelligent management system adopts software to seamlessly integrate with other park card management systems to realize the compatibility of IC cards in the parking lot with other systems in the park. Share an IC card and integrate it in the management platform of the application software to realize data sharing.
Solution in IC card business management 1. Add the card issuing method of the parking lot to the original all-in-one card issuance, and each system can be authorized after one issuance. This can not only complete the unified management of cards, but also complete the unified management of data. Our company provides card issuance format and database storage format.
2. Using the secondary setting method of parking lot subsystem, after the first all-in-one card is issued, our company reads the first issued user information from the database, and then writes the user information to the parking lot when the all-in-one card is issued. In the field system, ensure that the user information in the two systems is consistent. In this way, the operator needs to make a setting on the parking lot system, and operate the setting on the parking lot system and the all-in-one card system at the same time when reporting the loss. This requires the other party to provide the structure of the user’s public information table in the database.
The solution of the park’s all-in-one card clearing platform 1. Use an independent e-wallet. The parking lot will be deducted from the e-wallet of the parking lot when deducting fees. The other party provides the structure of the settlement table in the database. Our company saves the user’s parking charge information when parking charges. Once a copy is placed in the settlement table, the operator can print out various data consumed by the user in a certain period of time through the settlement platform.
2. Use the one-card public electronic wallet, the parking lot will deduct from the public electronic wallet when deducting the fee, and save a copy of the charging information in the settlement table. When the car owner owns the Yitong card of the “Park All-in-One Card”, it can support deduction from the Yitong card wallet in the card, and form the corresponding consumption records in the database for uploading to the “Park All-in-One Card” secondary clearing center to participate in the liquidation. .
Realize seamless compatibility with Xiamen Yitong card system. In the Q&A content of this tender supplementary document, the system needs to be compatible with the “Xiamen Yitong card” equipment and support the deduction, settlement, and settlement in the “Xiamen Yitong card” system. Fully compatible with statistics and other software; for the three main entrances and exits of the park for online transactions, the hardware:
The main board of the PLC control machine is designed with a small CPU card slot, which can be used to install the PSAM card provided by yitong card company. It uses embedded micro-control electronic control technology and combines PIM encryption and decryption to identify the calculation method and judge, which fully meets the system of the main controller hardware Seamless and compatible combination.
The electronic information display screen of the control machine in Chinese and English: In addition to the normal display of the current time, card expiration date, charge amount and other humanized information prompts, it is also designed to display text information such as the current EZ-link card balance in a timely manner, which is convenient for users. Master the balance and reminder of EZ-Link card whether you need to recharge in time, so that it is clear, efficient and practical.
For the IC card of a fixed car owner, a special area will be designated in the card for parking management or card authorization registration and issuance.
For the three intersection system software in the park for online transactions: software update and tailor-made will be carried out in accordance with the deduction standard process requirements provided by the yitong card company, and use the bottom and upper computer software programming programs to calculate, judge, complete statistics and sub-items statistics The combined method realizes the deduction, calculation and statistics of all yitong card amounts.
When the consumption is completed, the transaction records are stored according to the format of the EZ-Tong card. These transaction records are collected from the database of the back-end parking management system every day and uploaded to the secondary clearing system of the “Park Card” in accordance with the format required by the “Park Card” to participate in the liquidation. At the same time, according to the settlement result of the next day, download the settlement and reconciliation file from the “Park Card”, put it into the warehouse, and form a reconciliation report for the park parking management department to reconcile with the Yitong card.
The data combination of “Yitong card transaction” and “Park All-in-One Card”: Able to summarize the Yitong card transactions generated by each card swiping device at the entrance and exit of the park, and upload it to the second level of the “Park All-in-One Card” in the format required by the “Park All-In-One Card” Participate in liquidation in the liquidation system. It can also download the settlement and reconciliation file from the “Park Card”, put it into the warehouse, and form a reconciliation report for the park parking management department to reconcile with the Yitong card.
After the implementation of this system is compatible with the Xiamen Yitong card system, when a temporary vehicle enters the park, if you do not have a Yitong card, you need to press the key to obtain a temporary card and swipe the card to enter the door; if you have a Yitong card, you will directly use the Yitong card to enter the park; For those who have obtained a temporary card, swipe the card at the exit of the park for timing, billing, and pay cash; for the temporary vehicle itself with an EZ-Tong card, swipe the card at the exit of the park for timing and billing, if the card balance is sufficient for the fee , Deducted directly from the card. If the balance in the card is insufficient, pay in cash as required.
