【 Weak current College 】 intelligent parking system considerations before signing

When entering the parking system with customer specific discussions, you should be aware of the implementation of the following:

1, parking management system configuration

1) simple system: the system only configuration management vehicles access card read/write device, car, vehicle detector device and manage equipment, can also be combined with voice prompts, parking spaces and export screen, but generally not configure image comparison system, automatic issuing machine, automatic debt card machines, intercom device. This system is only for General Security vehicle, parking management, back-office computer just keep vehicles difference time records and parking fees, fees for temporary vehicle management shall have received artificial card issuing, card, cards easily lost, while temporarily temporary vehicle security have a certain risk. This system applies to those who only managed to owners of vehicles or just want to put a small amount of funds for car parks-building communities.

2) standard system: this is the most current use of a car system, configure the card read-write, voice prompts, car display, auto-out card machines, vehicles and sense detector, smart gates, garage equipment, while also configuring the import and export image capture comparison system, applied to the various vehicle parking management system, this system has a car a card's capabilities while also using image capture comparison system for vehicles with dual protection, admin computer not only has the time, vehicle access charges, while every two vehicles difference corresponds to the picture, can be preserved for incident provides important evidence. This is a more perfect management system.

3) enhanced system: this system has a standard parking system all of the features, configuration, on the basis of different special occasions and different customer requirements, the corresponding increase in the intercom, location boot display, document capture, traffic control, long range reader, voice prompts, and other functions to apply to all kinds of special places.

2. car park design dimensions

1) importers in the same intersection: for vehicles in the same location, you need to determine the facts under site entrance management equipment installation location, when the pass road width no more than 5 meters, the entrance and car devices sharing 1; when the pass road width is larger than 5 m and not more than 8 meters, access should be road design, automatic gates should also design separation; (due to domestic vehicle steering wheel located on the left side of the vehicle, the entrances of card reading devices should be installed in the appropriate location, so both layout and transport vehicles travelling in the rules on the right, so this kind of arrangement is limited to use within the community). When the pass road width of more than 8 m in the middle of the road, you will need to establish a fixed system equipment of refuges (General dimensions 5.5 m × 1.3 m × 0.18 m), the only way to convenient facilities, the owners of use and comply with the traffic rules.

2) entrances that are not on the same road: when communities within the access on a different channel, the main one is to consider the community within the flow direction, the direction for appearance, the design of this channel for exports, on the other hand, another channel for entrance; if the entrance channel has no special requirements, to close the channel service recently to export.

The above equipment layout needs according to a principle: that is the importers card reader equipment distance entrance car railing distance not less than 3 m, distance from the export charge box export car railing distance not less than 2.6 m; in addition the entrance card devices should be placed in a straight line channel, if it cannot bend avoided, it should allow sufficient distance for vehicles turning card, quka.

Volume 3, parking systems engineering

1) requires the implementation of vehicle entrances and longest distance between (mainly for separate entrances) to determine the number of pipe and wire.

2) needed to implement the vehicle entrances between road conditions, determine the layout of a pipeline is a pavement (concrete pavement, square brick pavement or turf surface) to determine the size of the construction volume.

3) for the entrance and at the same intersection, you need to confirm whether the construction of a fixed system devices, in addition, the island need to confirm whether you need paste porcelain refuges.

4. parking system management mode

1) does not set the Management Center: for independent entered an intelligent parking system, not in traffic, in order to reduce the construction cost of the system, you can set the background card authorization and data storage of server computers and export charges computer one (i.e., stand-alone parking system) that are installed in a outlet of on-duty room (or box) unified management.

2) settings management Center: for more than one export community or traffic flow larger communities, should headquarters financial room specifically set a management server, the service and the export charge computer through a network cable or optical fiber cable for joins, unified storage all export of vehicles and from data and card issuance, authorization for processing, while on the vehicle at any time, all of the data.

5, parking system information carrier selected

1) ID (Emid) RF card: for long-range reader users (generally refers to the reading distance of more than 20 cm), shall be in the ID reading and writing system, used by the owner as radiofrequency card Em card, the appropriate read/write recognition system for ID identification system. ID card feature is you can reach the distance or the ability of card ºnew, owners can distance card or not parking card, for owners of vehicles, this is an ideal system, but because of the ID card itself can only be read but not write information, so the whole system runs completely dependent on the background of the management computer, the computer cannot be divorced from the independent operation (hereinafter referred to as offline run), and for equipment wiring that is supporting communication devices require a high level, so that traffic flow is large sites or where the temporary vehicle, do not recommend using this system.

IC (Mifare-1) launchedRate card: for read and write distance requirements do not exceed 10 cm of the user, using IC card is ideal, because this card built-in storage CPU chip, you can identify information, while maintaining the information directly written on the card chip, on the background of the management of computer dependence on small, if the management computer failure, or communications line failure, the entire system can still be run independently, and store the data in the card reader device's microcontroller pending computer fault cleared, these data will automatically upload management computer permanently saved. In addition, this card built-in CPU is divided into 16 sectors, different systems of writing information to the different sectors (such as car parks, access control, attendance, etc.), the actual realization of a cartoon, this card has become a mainstream radio frequency card. This card is the reading distance near (generally 10 centimeters), relative high cost of the card.
