Vehicle positioning and parking lot parking space state management method and system

Abstract

The invention provides a vehicle positioning and parking lot parking space state management method and system. The method of the invention includes the following steps that: the entrance, exit, passages and parking spaces of a parking lot are marked with RFID electronic tags; an RFID vehicle-mounted terminal is arranged at a suitable position of a vehicle; and the RFID vehicle-mounted terminal reports read legitimate electronic tag IDs and reading time to a cloud platform through a communication module; and the cloud platform saves vehicle location information and parking lot parking space status information and updates the information periodically in real time, so that a query terminal can use the information. The system of the present invention includes RFID electronic tags, an RFID vehicle-mounted terminal, a vehicle service cloud platform, an inquiry terminal, and electronic signages. With the method and system provided by the invention adopted, vehicle positioning and parking lotparking space state accurate management and reservability are realized. The vehicle positioning and parking lot parking space state management method and system have the advantages of high accuracy, low cost, simple structure, easiness in deployment and maintenance, high concentration of the cloud platform, universality, compatibility and high extensibility.

Description

technical field [0001] The invention relates to the field of RFID electronic information technology, in particular to a method and system for vehicle positioning and parking space status management in a parking lot. Background technique [0002] The era of sharing economy has arrived, shared cars are gradually rising, and the problem of vehicle positioning is becoming more and more obvious. It is often encountered that when the previous user finishes using the shared car, the next user then reserves the car, but the user has no way of knowing where the other car is located. The parking space number and specific location of the scheduled shared car park, especially in large underground parking lots with more parking spaces, it is as difficult as hide and seek to find the vehicle blindly. [0003] At present, there is also a common problem that after the vehicle enters a large underground parking lot with many parking spaces, the driver has to wander around in the parking lot ...

Problems solved by technology

[0002] The era of sharing economy has arrived, shared cars are gradually rising, and the problem of vehicle positioning is becoming more and more obvious. It is often encountered that when the previous user finishes using the shared car, the next user then reserves the car, but the user has no way of knowing where the other car is located. The parking space number and specific location of the reserved shared car, especially in the large underground parking lot with many parking spaces, it is even more difficult to find the car blindly like hide and seek

[0003] At present, there is also a common problem that after the vehicle enters a large underground parking lot with many parking spaces, the driver has to wander around in the parking lot because the field of view of the underground parking lot is not wide enough. , wasting a lot of time, and it is easy to bring unnecessary trouble to the management of the parking lot

However, the method and system of this invention patent have the following defects and deficiencies: (1) the method proposed by this invention patent "has an electronic tag on the body of the vehicle, and RFID reader equipment is installed at the entrance of the parking lot", which not only makes the entire system The composition structure is too complex, it is not easy to deploy and maintain, the versatility and scalability are not good, and it increases the overall cost of the system, so there can be better alternatives

(2) The method proposed in the invention patent "an ordinary mobile communication terminal with an RFID reading function can be any device that can be used for wireless communication when carried by a user, such as a cellular phone, a personal digital assistant, etc.", in fact , such a mobile communication terminal has difficulties in product realization, it is not easy for most users to accept, and it is also difficult to promote from the market level

(3) The method "the second RFID tag stores the location information about the corresponding parking space" proposed by the invention patent, in fact, brings two problems: one is to write the specific information of the parking space into the RFID tag. It is difficult to operate, and the cost of deployment and maintenance management is significantly increased; second, it is easy to cause leakage of user location information

(4) In the method proposed by the invention patent, the ordinary mobile communication terminal with RFID reading function does not make a legality judgment on the second RFID tag, which has defects

(5) The method proposed in the invention patent did not fully explore the needs of RFID electronic tag technology in the intelligent management of parking lots, and did not mention the functional design and technical solutions for the status management of parking spaces in the parking lot

However, the method of this invention patent has the following defects and deficiencies: (1) the method proposed by this invention patent "the mobile terminal is a mobile phone, a tablet computer or a palmtop computer, and an electronic device that supports scanning of the parking space is installed in the mobile terminal. An application for tagging and electronic tagging of parking lot entrances and an application supporting the display of said floor plan"

In fact, one-dimensional code and two-dimensional code labels are easy to be defaced and damaged, affected by the brightness of the parking lot, and the usability is poor. Only RFID electronic tags are available

If the mobile communication terminal supports reading RFID electronic tags, it is difficult to realize the product, and it is not easy for most users to accept it, and it is also difficult to promote it from the market level.

(2) The method proposed by the invention patent does not propose the steps and methods for the mobile communication terminal to judge the validity of the RFID tag, which has obvious defects

In the real environment, there may be many kinds of RFID electronic tags. If the legality is not judged, a large amount of irrelevant electronic tag ID data will be sent to the background system for processing, resulting in a greatly reduced overall system efficiency, and may even cause the system to fail to work properly.

(3) The method proposed in this invention patent did not fully explore the needs of RFID electronic tag technology in the intelligent management of parking lots, and did not mention the functional design and technical solutions for the precise management of parking space status and bookability in the parking lot

However, the method and system of this invention patent have the following defects and deficiencies: (1) The method proposed by this invention patent "the vehicle-mounted terminal reads the parameter information of smart labels in different frequency bands set at the entrance of the car gate, driving lane and parking space, which is Through the automatic frequency modulation search function of the vehicle terminal, the automatic matching and reading of smart tags in different frequency bands is realized." The description of this technical solution is relatively vague and not clear enough. The vehicle terminal technology is difficult to implement and the cost is high.

"The description of this technical solution is vague, not clear enough, difficult to understand, the function and purpose to be realized are not clear, the technology is difficult to realize, and it is difficult to apply and promote it in practice

(5) The technical solution in the patent specification of the invention that "the background management subsystem only processes the relevant ID parameter information, so as to prevent mutual interference of data sources", has obvious defects

RFID electronic tag technology is a general-purpose technology. Each manufacturer produces and manufactures RFID electronic tags and RFID reader chips in accordance with unified international standards or national standards. When there are many kinds of RFID electronic tags in the parking lot, a large number of irrelevant electronic tags ID data will be sent to the background system for processing, which will greatly reduce the overall efficiency of the system, and may even cause the system to fail to work properly
