An intelligent parking lot query and charging system and method based on signs

Abstract

The invention discloses a sign-based intelligent parking lot inquiry and charging system and a method thereof. Set up a WIFI access point at each place that needs to receive parking information, place a mini WIFI module on the vehicle, and obtain the corresponding public-private key pair through mapping. The user searches the surrounding parking lot through the APP, finds the parking lot, reserves the parking space, and pays the parking deposit. After the user parks at the scheduled time, the mini WIFI module communicates with the WIFI access point for two-way verification. After the verification is passed, the management background obtains the corresponding account and vehicle information, and starts timing and billing. When the user drives away, the mini WIFI module loses the periodic handshake with the WIFI access point, and the WIFI access point sends the vehicle departure information to the management background. The management background finds the corresponding user data and calculates the parking amount, and automatically deducts the parking amount from the user's prepaid account. The present invention can be applied to parking places in various cities.

Description

technical field [0001] The invention relates to an intelligent parking lot system, in particular to a system and method for inquiring and charging a parking lot based on identification authentication, which is applicable to parking places in various cities. Background technique [0002] With the rapid development of the economy, the number of automobiles in China is showing a trend of rapid growth. The advent of the era of automobile consumption has correspondingly led to the rise and development of the parking industry. To solve the problem of vehicle parking, cities build parking lots in various public places such as commercial centers, large supermarkets, hospitals, restaurants, airports, and administrative centers to meet vehicle parking needs. . [0003] Affected by the Internet era, urbanization is gradually developing towards modernization and intelligence. The traditional parking lot model is increasingly showing its shortcomings. First, the labor cost is high, and ...

Problems solved by technology

[0003] Affected by the Internet era, urbanization is gradually developing towards modernization and intelligence. The traditional parking lot model is increasingly showing its shortcomings. First, the labor cost is high, and the parking lot toll office requires 7×24 hours of uninterrupted labor. Only by being on duty can the uninterrupted business of the parking lot be guaranteed; secondly, the computer itself has risks: due to the high working hours, the CPU is likely to crash due to high temperature, and the memory, graphics card and other plug-ins are easy to loose or damage

In terms of software, it is easy to be attacked by viruses and the system is easy to be destroyed. At the same time, long running time will lead to increased redundant data and slow down the system; the parking lot card is easily lost by the vehicle user, and the card cannot be provided for relevant personnel to bill when leaving the parking lot At the same time, the loss of the card will also bring a certain workload to the parking lot system itself and the maintenance personnel; again, when the vehicle leaves the parking lot, the card must be provided to the toll office, and the billing personnel can only collect the money after getting the billing amount. It takes about one minute to complete the series of processes of ticket printing and change. Just imagine, if the parking lot accommodates more than 1,000 people in crowded shopping malls, hospitals, etc., waiting in line for billing will be extremely difficult. It will be a long waiting process. The exit billing and toll office of the parking lot will be a huge challenge to the toll collectors. At the same time, the vehicles driving out of the parking lot will directly affect the situation of the vehicles entering the parking lot. Conditions affecting nearby traffic

Finally, the traditional parking lot simply records the entry and exit time of the vehicle, and the detailed billing rules are opaque to the user, and at the same time, it is impossible to verify the safety level of the user's vehicle

[0004] There are also some parking fee collection systems based on radio frequency electronic identification and license plate image recognition, which also show shortcomings in some aspects: the identification distance based on radio frequency electronic identification is limited, and the vehicle can only be read within the identification distance range and successfully read the label content. Correct billing, if the two vehicles are too close, it is easy for the second vehicle to successfully read the data but the first vehicle does not read the data, the error is high, and there are certain requirements for the speed of the vehicle; the license plate image recognition method is easy Affected by factors such as rain, snow, strong wind, smog, etc., and related to the angle of the photo, once the photo is blurred, the system cannot distinguish the license plate number and cannot bill correctly
