Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.
As shown in fig. 1, the present application provides a road parking charge management method based on a dedicated PDA, the method comprising the steps of:
s101: the parking detection device detects whether the vehicle is parked completely and sends a vehicle parking completion signal and a parking number to the cloud server;
after the vehicle is parked in the parking space, the parking detection device detects that the vehicle exists in the parking space and the parking state of the vehicle is stable, and sends vehicle parking completion information and the parking space number to the cloud server.
S102: the cloud server transmits the vehicle parking completion signal and the parking number to a charging manager PDA end;
the charge manager PDA end can be a handheld PDA device special for parking charge, the charge manager carries the PDA device with the charge manager in daily work, and the charge manager PDA end can be in wireless communication with the cloud server. And the cloud server sends the received vehicle parking completion signal and the parking number to the PDA device.
In the process, the PDA equipment can also automatically broadcast the vehicle parking completion information and the parking space number after receiving the vehicle parking completion signal and the parking space number information.
S103: the charge manager PDA terminal collects license plate number information of a parked vehicle according to the parking number and sends the collected license plate number information to the cloud server;
specifically, the charge manager PDA terminal takes a license plate photo through its own camera module and sends it to the cloud server.
The method comprises the steps that a cloud server can recognize license plate pictures uploaded by different PDA devices based on picture recognition and picture segmentation technologies, when the method is implemented specifically, a charge manager PDA end conducts photographing positioning through motion videos, meanwhile, multiple pictures are captured to be compared locally at the PDA end, the optimal license plate number picture is selected to be cut, license plate areas are reserved, and the pictures which are cut successfully are compressed and uploaded to the cloud server.
Or, the collecting, by the PDA end of the toll administrator, the license plate number of the parked vehicle according to the parking number may specifically be: the toll administrator broadcasts the license plate number information through voice; and the charge manager PDA terminal collects the voice broadcast license plate number information, performs intelligent voice special noise reduction processing, extracts the license plate number information in the noise-reduced voice signal and sends the license plate number information to the cloud server.
Before collecting license plate number, the charge manager uses PDA device to check whether the current parking number is matched with the driving-in parking number, and after the matching is confirmed, the camera module can be used for collecting license plate photo or selecting intelligent voice input to collect license plate number.
S104: the cloud server starts parking timing according to the received license plate number;
when the method is implemented, if the PDA device uses the camera module to collect the license plate number photos, the cloud server firstly identifies image texts through a two-dimensional convolution neural network according to the received license plate number photos, firstly identifies and cuts license plate multi-characters into independent characters, then extracts features of smaller pictures, and specifically can extract feature points of strong sunlight, light-reflecting license plates, distorted license plates, dim light, dark environments, street lamps and license plate shooting angles, and only needs to sense local parts to reduce operation amount and improve calculation efficiency. The images are divided into small blocks for comparison through pixel-to-pixel comparison, rough features (namely the small blocks) are found at approximately the same positions in the two images for matching feature mapping according to the standard images of the license plate as a exhibitions. The server sends the calculated license plate number to the PDA end, and after a charging manager confirms that the license plate number is correct, the cloud server stores the calculated license plate character characteristics and conducts original comparison training of a neural network. If the final license plate is modified and confirmed by the charge administrator, the cloud server can perform re-comparison on the license plate provided by the charge administrator, extract the difference between the comparison feature points and the sample, add new feature points, and improve the comparison efficiency of the next time.
And after the determined license plate number is extracted, the cloud server starts parking timing.
S105: the cloud server judges whether payment request information sent by the mobile client is received or not;
when the user finishes parking and drives away from the parking space, the APP can be used for scanning the payment two-dimensional code to apply for payment to the cloud server, payment request information is sent to the cloud server, and meanwhile the cloud server judges whether the payment request information is received or not.
S106: if so, stopping timing, generating payment information and sending the payment information to the mobile client;
and when the cloud server receives the payment request information, stopping parking timing, calculating parking fee according to the set rate and parking time, generating payment information containing the fee, issuing the payment information to a user, and performing payment.
S107: if not, further judging whether a vehicle driving-away signal sent by the parking detection device is received, and if so, recording the unpaid fee information.
If the cloud server does not receive the payment request information, whether a vehicle driving-away signal sent by the parking detection device is received or not is further judged, if the vehicle driving-away information is received, the fact that the vehicle is not paid and leaves is indicated, at the moment, the cloud server can record the information that the vehicle is not paid according to the license plate information, the information is provided for the user through app, the user without app can print the times and the amount of arrearage on a receipt for synchronous payment when parking next time. If the fee is not paid multiple times, the toll collector may request the user to make a cash or network payment, or prohibit the vehicle from parking. After the payment is made, the vehicle is allowed to stop again.
Based on the technical scheme, the method and the system can realize the road parking charging management with low cost, high efficiency, small management loophole and intelligent link of the whole industrial chain; the system has the arrearage recording function, reduces the phenomena of 'stop rubbing', fee evasion and fee leakage caused by weak self-payment consciousness of part of personnel, can effectively ensure the payment due to the payment of the parking fee and stabilize the municipal income.
