Description

Coordinate system-based parking space numbering method for underground parking lot

Technical Field

The invention relates to the technical field of underground parking garage plane layout and parking space coding, in particular to a parking space numbering method based on a coordinate system for an underground parking garage.

Background

At present, most of foreign parking lot management systems are equipped with parking space guidance systems, parking space inquiry systems and other intelligent devices, and the functions enable the reverse vehicle searching modes to be more perfect and abundant. The management mode of the novel parking lot adapts to the era of the current information-based high-speed development, and the function range and the function of the internet related technology in the parking lot management system are greatly expanded and extended. However, it is undeniable that the cost of the whole system is very high while a lot of electronic information technologies are adopted in the parking lot, and the larger the parking lot is, the more difficult the technology is to implement, and moreover, the maintenance cost of the system reaches a high level.

The domestic parking lot management system is generated and gradually developed along with the increasing of the domestic automobile ownership and the mass appearance of domestic public parking lots. Early domestic parking lots are simply divided into parking spaces, and the initial domestic parking lot management system is gradually developed on the basis of introducing, digesting and absorbing foreign similar systems, and is continuously improved on the basis. In the early development stage, as a plurality of key devices cannot be produced domestically, the parking lot management system hardware mostly adopts foreign products, so that the domestic parking lot management system at this stage has more integrated meanings.

At present, the novel parking lot management system in China is still in the primary stage of application, and a plurality of management systems expose some problems in practical use, and the performance is as follows: the system design of some management systems is not reasonable and perfect enough, and the actual national conditions of China cannot be fully considered, so that the novel field management technology cannot play a due role in practical application. On the contrary, some parking lots adopt new technical equipment which becomes a bottleneck for restricting the management system to exert the management function.

The prior art still has the following disadvantages:

1. card swiping and vehicle finding device

The card swiping and vehicle searching method comprises the steps that firstly, an IC card which needs to be carried about is sent to a driver user by a parking lot manager when a vehicle is in a parking lot, and secondly, a plurality of terminal devices which can be used for the card swiping and positioning of the driver are installed in each area of the parking lot so that the user can mark parking spaces. After the parking is successful, the IC card is used for carrying out card swiping positioning on a card swiping positioning terminal near the parking space, and information such as the parking space position of a driver, the parking time and the like is sent to the parking lot control computer. When the driver user returns to the parking lot after the completion of the transaction, the information of the vehicle searching path can be displayed by swiping a card on the inquiry machine near the entrance (CN 201838193U).

The method comprises the following steps: the user needs to carry the IC card, and the IC card is inconvenient to carry and has a loss risk; the hardware cost for installing the positioning machine and the query machine in the parking lot is high, and factors such as communication wiring, power supply and the like cause the installation to be complicated; in addition, the positions and the number of the positioning machines and the inquiry machines installed in the parking lot can influence the working performance of the system, and a user needs to independently find the position of the machine, so that the vehicle searching difficulty is increased.

2. Vehicle searching by video identification technology

The video identification technology captures parking space and vehicle pictures through a camera above the parking space, judges the parking space occupation condition by using the image identification technology and extracts a license plate number to complete the positioning of the vehicle; storing the license plate number and the corresponding position information in a database; the user can search the accurate position of the favorite car by inputting the keyword of the license plate number of the user through a car searching machine arranged in the field.

The method comprises the following steps: a plurality of high-resolution cameras and vehicle finding and inquiring machines need to be installed in the parking lot, the system hardware cost is high for a large parking lot, and early deployment and later maintenance are relatively complex; meanwhile, the precision of video recognition of the license plate is limited, and the license plate is easily affected by fouling, rusting and irregular installation position.

3. Vehicle searching by RFID (radio frequency identification) technology

Active RFID card location is achieved by installing multiple RFID readers in appropriate locations in the parking lot so that each slot is covered within the reading range of the RFID readers. The customer will pick up two cards, one active RFID card remains on the car for marking the position of the car in the parking lot, and the other card associated with it needs to be carried with the user, and the reverse car-finding is realized by querying on the querying terminal.

The method comprises the following steps: firstly, enough RFID readers are needed to cover the whole parking lot, so that the investment cost of the parking lot is high; secondly, the cost of the active RFID card is also high, and once the loss is large, the operation of the two cards is cumbersome.

4. Vehicle searching by wireless network positioning technology

The wireless network positioning technology is a specific application of an indoor positioning technology represented by a WiFi fingerprint positioning technology in a parking lot. The system completes system construction after signal intensity acquisition of WiFi hotspots of all positions in the parking lot in the early stage and an off-line training stage in the later stage. After a driver user enters a parking lot, a client installed on a user smart phone sends a field intensity signal of the position where the user is located in real time; the field intensity signal is compared with a position signal stored in the parking lot management server, and then the real-time position of the user is determined. After the parking is successful, selecting a marked parking space at the mobile phone client to operate so as to realize accurate locking of the position of the vehicle; when finding the car, the user inquires the position of the car at the mobile phone end and informs the user of the car finding path in a plan view form (CN 104537873A).

The method comprises the following steps: firstly, wireless network positioning requires full coverage of signals in a parking lot, and the requirement on communication is high; secondly, the positioning accuracy is relatively poor, the wireless signal strength changes at any time, the wireless signal is easily affected by the environment, and the signal is unstable. Although the positioning accuracy can be improved by increasing the hot spot density and the real-time correction of the position fingerprint information, the system cost and the technical difficulty are increased.

5. Vehicle searching based on two-dimension code technology

The vehicle searching system based on the two-dimensional code technology generates a positioning two-dimensional code containing position information after calibrating the position of each area in a parking lot, and posts the positioning two-dimensional code at the position corresponding to each area. If a driver needs to use the reverse car searching function after entering a field, a self-contained smart phone is used for scanning and positioning the two-dimensional code, and the parking space information is sent to a parking lot database; when a vehicle needs to be searched, a user scans a two-dimensional code of the searched vehicle nearby, inquires a vehicle searching path while informing the position of the system, inquires a parking space position marked by the user in the earlier stage after the system receives a request, and sends the parking space position to the user after the path is planned.

The method comprises the following steps: firstly, the two-dimension code technology needs full signal coverage in a parking lot and has higher requirement on communication; secondly, the method provides a car-searching path diagram, the position of a user cannot be updated in real time, and the car searching still has certain difficulty; if the user does not scan the two-dimensional code at the parking place after parking, the function of the vehicle searching system cannot be realized.
