With the development of automation technology, self-service services gradually move into people's lives. In existing fueling stations, when a vehicle is being fueled, a worker is required to activate a fueling controller using a specific IC card to provide fueling services. This requires that the service stations need twenty-four hours to be staffed by staff, especially at service stations with low availability, which greatly increases labor costs.
In view of this, the present application provides a self-service refueling system based on video monitoring, referring to fig. 1, the system includes:
an intelligent camera 101, a fueling controller 102, a radar 103, and a server 104, wherein the intelligent camera 101 is connected to the radar 103, the intelligent camera 101 is connected to the server 104, and the intelligent camera 101 is connected to the fueling controller 102;
the smart camera 101 described above is configured to: acquiring image data of a first monitoring area, detecting and analyzing the image data, sending license plate information to the server 104 when license plate information of a vehicle is detected in the image data, and triggering and starting the radar 103;
the radar 103 is configured to: responding to the starting trigger of the intelligent camera 101, detecting the distance between the vehicle and the radar 103 in real time, and sending a distance detection result to the intelligent camera 101;
the server 104 is configured to: acquiring the license plate information, judging whether an account corresponding to the license plate information has an oiling right, and sending an oiling permission instruction to the intelligent camera 101 when the account corresponding to the license plate information has the oiling right;
the smart camera 101 described above is also configured to: when an instruction of allowing refueling is received and the distance detection result returned by the radar 103 meets a preset refueling distance rule, the refueling controller 102 is started;
the refueling controller 102 is configured to: and under the condition of starting, corresponding refueling operation is executed according to a refueling instruction input by a user.
In the embodiment of the application, the smart camera 101 is connected to the radar 103, the smart camera 101 is connected to the server 104, and the smart camera 101 is connected to the fueling controller 102, which are all in communication connection, and may be connected in communication manners such as wired or wireless. Specifically, the smart camera 101 may be connected to the radar 103 through an RS232 (asynchronous transfer standard Interface) line, the smart camera 101 may be connected to the Server 104 through an ISAPI (Internet Application Programming Interface) protocol, and the smart camera 101 may be connected to the fueling controller 102 through an RS232 line or an RS485 line.
The smart camera 101 keeps acquiring image data of a designated monitoring area and performs inspection analysis on the acquired image data, for example, license plate recognition. When a vehicle to be refueled enters a designated monitoring area, the intelligent camera 101 extracts license plate information of the vehicle, sends the license plate information to the server 104, and simultaneously starts the radar 103.
Alternatively, referring to fig. 2, the smart camera 101 may include: ISAPI module, license plate identification module, radar control module, data processing module and warning output module.
The ISAPI module is used for aiming at the program interfaces of the server and the control; the license plate recognition module is used for recognizing license plate information in the image data; the radar control module is used for controlling the turning on and off of the radar; the data processing module is used for processing data sent by the radar and the server; the alarm input module is used for controlling the opening and closing of the refueling controller.
Optionally, referring to fig. 3a, the smart camera 101 is an ANPR (Automatic Number Plate Recognition) camera, and the ANPR camera analyzes and allows detecting and recognizing a vehicle license Plate, and sends ANPR information to a smart NVR (Network Video Recorder) or VMS (Video Management System) software for access Management. The matching captured license plate picture and related information can be searched and viewed according to license plate search conditions including start time/end time, country and license plate number. Detecting and identifying license plate numbers, country information, capturing related images, speed information (radar), etc.
The ANPR camera is installed above the fueling controller 102, and the ANPR camera is installed at an angle that captures images of a location 1/3-1/2 away from an end of the ANPR camera in a fueling area and ensures that a license plate of a vehicle is kept horizontal in an image captured by the ANPR camera when the vehicle enters the fueling area. The height of the license plate characters in the image collected by the ANPR camera can be less than 200 pixel points, and the width of the license plate characters is between 20 and 30 pixel points, so that the ANPR camera can shoot license plate information of a vehicle, and the optimal license plate recognition effect is guaranteed.
The radar 103 is installed in the position of refueling controller 102 below when stopping the vehicle and refueling, and the mounting height is not higher than the vehicle body and the distance on ground when refueling the position, and the radar is no longer than 2 meters away from the vehicle body when the vehicle stops to refuel, guarantees that the vehicle can detect when refueling the regional refueling that the vehicle has the vehicle to refuel in the region.
The ANPR camera can communicate with the range radar through an RS232 line, and the functions of controlling the range radar to start and stop the range function and feeding back the range distance and radar state information by the range radar are realized through a self-defined protocol. The ANPR camera is used for controlling the range radar, so that the purpose of prolonging the service life of the range radar can be achieved.
The intelligent camera 101 starts the refueling controller 102 means that the intelligent camera 101 enables the refueling controller 102 to be in a working state through an electric signal, and enables the refueling controller 102 to be in a state of allowing refueling operation; the intelligent camera 101 turning off the fueling controller 102 means that the intelligent camera 101 turns off the fueling controller 102 by an electric signal, and the fueling controller 102 is in a state where the fueling operation is disabled.
In this application embodiment, intelligent camera, refuel controller, radar and server mutually support and have realized the self-service refueling of vehicle, have reduced the cost of labor. And the situation that the refueling controller is opened by mistake can be greatly reduced by adopting a method that an intelligent camera is matched with a radar for positioning.
Optionally, the distance detection result returned by the radar 103 meets a preset fueling distance rule, including: the distance detection result represents that the vehicle reaches a specified refueling area within first preset time, and the staying time of the vehicle in the specified refueling area is not less than second preset time.
The first preset time is used for filtering the situation that the intelligent camera detects the license plate information of the vehicle, but the vehicle does not drive into the designated refueling area. The second preset time is used for judging whether the vehicle stops and is refueled, when the residence time of the vehicle in the specified refueling area reaches the second preset time, the vehicle is considered to stop in the refueling area to refuel, and if the residence time is less than the second preset time, the vehicle is considered to pass by but not refuel. The setting of the first preset time and the second preset time can reduce the false opening condition of the refueling controller. The first preset time and the second preset time are both set according to the actual driving condition of the vehicle, for example, the first preset time may be set to 10 seconds, 15 seconds, 20 seconds, or the like. The second preset time may be set to 15 seconds, 20 seconds, 30 seconds, or the like.
The first monitoring area monitored by the smart camera 101 may be the same as or different from the designated fueling area, and in order to ensure that there is enough operating time for the smart camera 101 to activate the radar, optionally, the smart camera is an automatic license plate recognition (ANPR) camera, the first monitoring area is different from the designated fueling area, the ANPR camera is installed at an angle capable of capturing images at positions 1/3-1/2 of the designated fueling area away from the ANPR camera, and the first monitoring area and the designated fueling area are schematically illustrated in FIG. 3 b. Certainly, in order to acquire the license plate information of the vehicle as early as possible, the range of the first monitoring area may be appropriately increased, but the range of the first monitoring area is not suitable to be too large, because the radar 103 is frequently started by mistake when the range of the first monitoring area is too large.
Optionally, the smart camera 101 is further configured to: and when the distance detection result returned by the radar 103 ensures that the vehicle drives away from the designated refueling area, the refueling controller 102 and the radar 103 are turned off.
The intelligent camera 101 determines the distance from the vehicle to the radar 103 according to the distance detection result returned by the radar 103, and judges that the vehicle is away from the specified refueling area when the distance from the vehicle to the radar 103 exceeds the preset refueling area distance. After the vehicle leaves the designated refueling area, it indicates that the vehicle is completely refueled, the intelligent camera 101 turns off the refueling controller 102 to prevent lawless persons from invading the interests of users by using the refueling controller 102 after the vehicle leaves, and simultaneously, the intelligent camera 101 turns off the radar 103 to reduce the service life of the radar 103, thereby prolonging the service life of the radar 103.
Optionally, the smart camera 101 is further configured to: if the opening time of the refueling controller 102 reaches a third preset time, the refueling controller 102 and the radar 103 are turned off.
If the opening time of the refueling controller 102 reaches the third preset time, which indicates that the vehicle stays in the refueling area for too long, the smart camera 101 turns off the refueling controller 102 and the radar 103 to prevent an accident. The third predetermined time should be greater than the second predetermined time and the third predetermined time should ensure that the vehicle has sufficient time to perform the refueling action, for example, the third predetermined time may be set to 20 minutes, 30 minutes, 40 minutes, or the like.
Optionally, the smart camera 101 is further configured to: acquiring fueling data of the fueling controller 102, and sending the fueling data to the server 104;
the server 104 is further configured to: and updating the refueling authority of the account corresponding to the license plate information according to the refueling data.
The refuelling data may include the refuelling amount or the refuelling liter number of the corresponding vehicle. The smart camera 101 obtains fueling data of the fueling controller 102, where the fueling data may be reported to the smart camera 101 by the fueling controller 102 after fueling is completed by the user, or may be reported to the smart camera 101 by the fueling controller 102 when a preset reporting condition is met before fueling is met by the user, for example, after the user inputs a fueling amount or a fueling upgrade number through the fueling controller 102. Of course, in the embodiment of the present application, the fueling data may also be acquired by the smart camera 101 from the fueling controller 102, for example, the fueling data may be acquired from the fueling controller 102 before the smart camera 101 turns off the fueling controller 102. The smart camera 101 sends the acquired fueling data to the server 104, and the server 104 updates the fueling authorization of the corresponding account according to the fueling data, for example, updates the balance of the corresponding account. The fueling data may further include information such as the current fueling address and time, and the server 104 records the information after acquiring the information, so as to facilitate subsequent query.
Optionally, the server 104 is further configured to: when the account corresponding to the license plate information has no oiling right, an oiling prohibition instruction is sent to the intelligent camera 101;
the smart camera 101 described above is also configured to: upon receiving a command to disable fueling, the fueling controller 102 and the radar 103 are turned off or remain off.
The account corresponding to the license plate information has no oiling authority, and comprises that the license plate information is not registered, the account balance corresponding to the license plate information is insufficient, the oiling place is out of an available area of the account corresponding to the license plate information, and the like. The smart camera 101 turns off or keeps off the fueling controller 102 and the radar 103 when receiving the fueling prohibition instruction.
When the smart camera 101 is an ANPR camera, the ANPR camera needs to be configured to ensure normal use of the ANPR camera. The ANPR camera configuration includes two aspects: the first is to report the host IP (Internet Protocol, network Protocol address) and port configuration, and the second is to detect and configure the vehicle. The configuration reporting host IP and the port are realized through an ISAPI protocol and used for reporting the license plate recognition result to the server for fuel filling information comparison. The vehicle detection comprises license plate identification parameter configuration and refueling area information configuration.

The vehicle inspection parameter configuration interface may be as shown in fig. 5, where Height: when the refueling position is indicated to have a car, the distance between the ranging radar probe and the car is in centimeters. Infilace Time: the vehicle in-position time, i.e., the first preset time, represents the time in seconds from when the ANPR camera recognizes the license plate to when the vehicle travels to the fueling area. The first preset time is used for filtering a scene that the ANPR camera detects the license plate but the vehicle does not drive into the refueling position. Min responsiveness Time: the minimum stay time of the vehicle, namely the second preset time, represents that when the stay of the vehicle in the refueling area reaches the value, the vehicle is considered to be detected, and the ANPR camera triggers the alarm to output; if the dwell time is less than this value, the vehicle is deemed not to be refueled and no alarm output is triggered. Max responsiveness Time: and if the distance detected by the ranging radar is still smaller than the set Height value when the camera exceeds the value after triggering the alarm output, unconditionally triggering to finish the alarm output.
The license plate information reporting address configuration supports an IPV4(Internet Protocol Version 4) address format, and as shown in fig. 6, a user is required to fill in a corresponding fueling information management system and an IP and a corresponding open port.
The working process of the self-service refueling system based on video monitoring of the embodiment of the application mainly comprises the following steps:
detecting the vehicle entering the refueling area: when a vehicle needs to be refueled, the vehicle drives into a refueling area from a non-refueling area, as shown in fig. 7, before the vehicle completely stops in the refueling area, an ANPR camera captures a license plate of the refueling vehicle for license plate recognition, and reports the recognized license plate information to a server which is configured with an IP and a port in advance through an ISAPI protocol for information comparison, and meanwhile, the ANPR camera starts a distance measuring radar to start detecting whether the vehicle drives into the refueling area. And if the radar still does not detect that the vehicle enters the refueling area after the first preset time is exceeded, the ANPR camera closes the range radar and continues to perform the next vehicle refueling detection.
Vehicle stay detection in refueling area: referring to fig. 8, if the vehicle enters the refueling area within the first preset Time (infilace Time), that is, the radar detects that the vehicle enters the refueling area, the staying Time in the refueling area exceeds the set second preset Time (Min tolerance Time), and the server compares that the license plate is registered and bound with a refueling card or a refueling account, it indicates that the refueling vehicle has the refueling authority, and the ANPR camera triggers an alarm output to start the refueling device in linkage, so that refueling can be started.
Vehicle drive-off refueling area detection: referring to fig. 9, when the vehicle is refueled and moves away from the refueling area, the ANPR camera controls the radar to be turned off, the alarm output linkage is finished, and the system turns off the oil gun.
The embodiment of the application also provides a self-service refueling method based on video monitoring, referring to fig. 10, which is applied to a self-service refueling system based on video monitoring, wherein the self-service refueling system based on video monitoring comprises an intelligent camera, a refueling controller, a radar and a server, the intelligent camera is respectively connected with the radar, the server and the refueling controller, and the method comprises the following steps:
