[0046] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] In a first aspect, an embodiment of the present invention provides an oil theft prevention alarm device, which may be a device with data processing function, such as a personal computer (PC), a notebook computer, or a server.

[0048] Reference Figure 1 , Figure 1This is a schematic diagram of the hardware structure of the oil theft prevention alarm device involved in the embodiment of the present invention. In the embodiment of the present invention, the oil theft prevention alarm device may include a processor 1001 (such as a central processing unit, CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components; the user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard); the network interface 1004 may optionally include a standard wired interface, a wireless interface (such as a wireless fidelity WIreless-FIdelity, WI-FI interface); the memory 1005 may be a high-speed random access memory (random access memory, RAM), or a stable memory (non-volatile memory), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001. Those skilled in the art will understand that, Figure 1 The hardware structure shown in the figure does not constitute a limitation of the present invention, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0049] Continue to refer to Figure 1 , Figure 1 Memory 1005, a computer storage medium, may include an operating system, a network communication module, a user interface module, and an anti-oil theft alarm program. Processor 1001 may invoke the anti-oil theft alarm program stored in memory 1005 and execute the anti-oil theft alarm method provided in an embodiment of the present invention.

[0050] In a second aspect, an embodiment of the present invention provides an anti-oil theft alarm method.

[0051] In one embodiment, referring to Figure 2 , Figure 2 FIG. 1 is a flow chart of an embodiment of an anti-theft oil alarm method of the present invention. Figure 2 As shown, the anti-oil theft alarm method includes:

[0052] Step S10, detecting whether a pedestrian is carrying a target item using a first sensor and a second sensor, wherein the target item is an item carried by the pedestrian that exists in the item database, the first sensor is a camera, and the second sensor is a millimeter-wave radar or a lidar;

[0053] In this embodiment, the first sensor is a camera, which is pre-trained based on pictures of theft tools, and the pictures of theft tools are stored in the item database, so that the camera can identify whether there are target items in the item database from the items carried by pedestrians.

[0054] The second sensor, a millimeter-wave radar or lidar, is extensively tested against various theft tools in the item database. The second sensor can identify radar scattering area reflectance values ​​and other characteristics of different theft tools, and classify them. This allows the second sensor to identify target items in the item database from among items carried by pedestrians. As you can imagine, in this embodiment, theft tools include all tools used in theft.

[0055] Furthermore, in one embodiment, referring to Figure 3 , Figure 3 for Figure 2 Detailed flow chart of step S10 in FIG. Figure 3 As shown, step S10 includes:

[0056] Step S101: Detecting pedestrians and target objects using a first sensor and a second sensor, wherein the first sensor is a camera and the second sensor is a millimeter-wave radar or a laser radar;

[0057] Step S102: When the first sensor identifies a pedestrian and a target object, the detection result is that a pedestrian is carrying the target object;

[0058] Step S103, when the second sensor recognizes the pedestrian and the target object, and the first sensor does not recognize the pedestrian and the target object, determining the current weather according to the weather signal;

[0059] Step S104: If the current weather is rainy, snowy or foggy, the detection result is that there is a pedestrian carrying the target object.

[0060] In this embodiment, pedestrians and target objects are detected using a camera and a millimeter-wave radar or a laser radar. Although both the camera and the millimeter-wave radar or laser radar can identify pedestrians and target objects, the camera is prone to missed or misidentified detection in inclement weather, such as rain, snow, or fog. While the millimeter-wave radar or laser radar is not affected by various climatic environments, they are prone to missed or misidentified detection regardless of the climatic environment. Therefore, when only the first sensor identifies the pedestrian and target object, or when both the first sensor and the second sensor identify the pedestrian and target object, that is, as long as the first sensor identifies the pedestrian and target object, regardless of whether the second sensor identifies the pedestrian and target object, the detection result is that a pedestrian is carrying a target object.

[0061] If only the second sensor detects a pedestrian and a target object, but the first sensor does not, the current weather is determined based on the weather signal. If the current weather is rainy, snowy, or foggy, the first sensor is considered to have failed, and the detection result is that a pedestrian is carrying the target object. If the current weather is good, such as sunny or with low haze, the second sensor is considered to have failed, and the detection result is that no pedestrian is carrying the target object.

[0062] If the first sensor and / or the second sensor only recognizes a pedestrian or a target object, the detection result is that there is no pedestrian carrying the target object. The combination of camera and millimeter wave radar or lidar for detection and judgment greatly improves the accuracy of the detection results.

[0063] Step S20, when the detection result indicates that a pedestrian is carrying the target object, obtaining the distance between the pedestrian carrying the target object and the vehicle fuel tank;

[0064] In this embodiment, when the detection result indicates that a pedestrian is carrying a target object, the distance between the pedestrian carrying the target object and the vehicle fuel tank is acquired through the first sensor and the second sensor.

[0065] Furthermore, in one embodiment, step S20 includes:

[0066] When the detection result indicates that a pedestrian is carrying a target object, the lateral distance between the pedestrian carrying the target object and the vehicle fuel tank is obtained by the first sensor, and the longitudinal distance between the pedestrian carrying the target object and the vehicle fuel tank is obtained by the second sensor;

[0067] The distance between the pedestrian carrying the target object and the vehicle fuel tank is calculated based on the lateral distance and the longitudinal distance.

[0068] In this embodiment, when the detection result indicates that a pedestrian is carrying a target object, the first sensor is used to obtain the lateral distance between the pedestrian carrying the target object and the vehicle's fuel tank. That is, the lateral distance between the pedestrian carrying the target object and the vehicle's fuel tank is based on the distance measured by the first sensor. The second sensor is used to obtain the longitudinal distance between the pedestrian carrying the target object and the vehicle's fuel tank. That is, the longitudinal distance between the pedestrian carrying the target object and the vehicle's fuel tank is based on the distance measured by the second sensor.

[0069] If the pedestrian carrying the target object is just in front of or behind the vehicle's fuel tank, the lateral distance measured by the first sensor is zero. If the pedestrian carrying the target object is just to the left or right of the vehicle's fuel tank, the longitudinal distance measured by the second sensor is zero.

[0070] If the pedestrian carrying the target object is diagonally in front of or behind the vehicle's fuel tank, the distance between the pedestrian carrying the target object and the vehicle's fuel tank can be calculated based on the lateral distance and longitudinal distance using trigonometric function theorem.

[0071] Step S30: adopting a corresponding alarm strategy based on the distance.

[0072] In this embodiment, after the distance between the pedestrian carrying the target object and the vehicle fuel tank is obtained, a corresponding alarm strategy is adopted based on the distance between the pedestrian carrying the target object and the vehicle fuel tank.

[0073] Furthermore, in one embodiment, referring to Figure 4 , Figure 4 for Figure 2 Detailed flow chart of step S30 in FIG. Figure 4 As shown, step S30 includes:

[0074] Step S301: When the distance is greater than or equal to the second preset distance and less than the first preset distance, output a first-level alarm prompt, wherein the first-level alarm prompt is a light prompt;

[0075] Step S302: When the distance is greater than or equal to the third preset distance and less than the second preset distance, output a second-level warning prompt, wherein the second-level warning prompt is a light prompt and a sound prompt;

[0076] Step S303, when the distance is less than the third preset distance, detect whether the pedestrian carrying the target object stays longer than the preset time. If longer than the preset time, output a three-level alarm prompt, wherein the three-level alarm prompt includes light prompt, sound prompt and calling the owner.

[0077] In this embodiment, the first preset distance is 15m, the second preset distance is 5m, and the third preset distance is 1m. When the distance between the pedestrian carrying the target object and the vehicle tank is greater than or equal to 5m and less than 15m, a first-level alarm prompt, that is, a light prompt, is output, thereby playing a preliminary warning role and providing lighting for the first sensor camera to collect the picture, so that the picture collected by the first sensor camera is clearer.

[0078] When the distance between a pedestrian carrying a target object and the vehicle's fuel tank is greater than or equal to 1m and less than 5m, a secondary warning prompt, namely a light prompt and a sound prompt, is output to attract the attention of other vehicles and pedestrians in the surrounding area, and intensify the warning to suspicious persons.

[0079] When the distance between a pedestrian carrying a target item and the vehicle's fuel tank is less than 1 meter, the system detects whether the pedestrian's presence is greater than a preset duration. If so, the system determines that the pedestrian carrying the target item is about to commit theft and issues a three-level warning: a light alert, an audible alert, and a phone call to the vehicle owner. The T-box (telematics) system will not stop calling the vehicle owner until the call is answered. Furthermore, if the pedestrian's presence is less than or equal to the preset duration, the system continues to implement a warning strategy based on the distance between the pedestrian carrying the target item and the vehicle's fuel tank.

[0080] In this embodiment, a first sensor and a second sensor are used to detect whether a pedestrian is carrying a target item. Items carried by the pedestrian that are present in an item database are considered target items. The first sensor is a camera, and the second sensor is a millimeter-wave radar or lidar. When the detection result indicates that a pedestrian is carrying a target item, the distance between the pedestrian carrying the target item and the vehicle's fuel tank is obtained, and a corresponding alarm strategy is implemented based on this distance. This embodiment improves the accuracy of the detection results by jointly detecting pedestrians and target items using the first and second sensors. The implementation of a corresponding alarm strategy based on the detection results of the first and second sensors and the distance between the pedestrian carrying the target item and the vehicle's fuel tank reduces the probability of false alarms, thereby resolving the low accuracy issue of existing anti-fuel theft solutions.

[0081] Furthermore, in one embodiment, the anti-oil theft alarm method further includes:

[0082] While outputting the first level alarm prompt, the second level alarm prompt and the third level alarm prompt, the first sensor is controlled to collect images;

[0083] After the step of adopting a corresponding alarm strategy based on the distance, the method further includes:

[0084] When the distance between the pedestrian carrying the target object and the vehicle's fuel tank is greater than or equal to a first preset distance, the alarm prompt is stopped and the image collected by the first sensor is uploaded to the cloud.

[0085] In this embodiment, while outputting the first-level alarm prompt, the second-level alarm prompt and the third-level alarm prompt, the first sensor is controlled to collect images, that is, as long as the distance between the pedestrian carrying the target object and the vehicle tank is less than the first preset distance, the first sensor is controlled to collect images.

[0086] When the distance between the pedestrian carrying the target object and the vehicle's fuel tank changes from greater than or equal to the second preset distance and less than the first preset distance, to greater than or equal to the third preset distance and less than the second preset distance, then to less than the third preset distance, and finally to greater than or equal to the first preset distance, it indicates that the pedestrian carrying the target object has passed the vehicle's fuel tank and has moved away. At this time, the alarm prompt stops, and the image captured by the first sensor is uploaded to the cloud for the vehicle owner to view the output of the first, second, and third level alarm prompts. If the distance between the pedestrian carrying the target object and the vehicle's fuel tank is not detected to be less than the first preset distance for a consecutive preset number of times, it is determined that the distance between the pedestrian carrying the target object and the vehicle's fuel tank is greater than or equal to the first preset distance.

[0087] In a third aspect, an embodiment of the present invention further provides an anti-oil theft alarm device.
