Abstract

The invention discloses an oil stealing prevention monitoring method, system and device for an oil tank of a truck. The method comprises the steps that the running state of the truck is obtained; if it is determined that the operation state of the truck is switched to the parking state, the initial liquid level value of a truck oil tank is detected; a real-time liquid level value of a truck fuel tank is obtained, and whether the real-time liquid level value is lower than the initial liquid level value or not is judged; if the real-time liquid level value is lower than the initial liquid level value, camera shooting equipment is controlled to be started, and the shooting direction of the camera shooting equipment faces the oil tank; judging whether a person is at the oil tank of the truck or not according to image information shot by the camera equipment; if yes, alarm information is sent; and if it is judged that no person exists at the truck oil tank, the initial liquid level value is updated to be the currently detected liquid level value. When the change of the liquid level of the oil tank detected in real time is abnormal, the camera shooting device is triggered to start shooting, the oil stealing condition of the oil tank is judged through image recognition, and oil stealing prevention monitoring of the oil tank is effectively and accurately achieved.

[0002] Logistics is centered on warehousing and promotes synchronization between production and the market. Logistics is the whole process of planning, implementation and management of raw materials, semi-finished products, finished products and related information from the place of production to the place of consumption of goods through transportation, storage and distribution to meet the needs of customers at the lowest cost. At present, the logistics industry is developing rapidly, and trucks have become one of the important means of transportation.

[0003] During the entire process of logistics transportation, especially long-distance transportation, in order to avoid fatigue, drivers usually stop to rest after driving for a certain period of time. Since the fuel tanks are mostly external, it is easy for the driver to rest, especially at night, without the opportunity to extract the fuel from the tank, causing economic losses to the driver.

BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 A flow chart of a method for monitoring fuel tanks against oil theft for trucks proposed by the present invention; DETAILED DESCRIPTION

[0031] like Figure 1 As shown, Figure 1 This is a flow chart of a method for monitoring fuel tanks against oil theft in trucks according to an embodiment of the present invention;

[0032] Reference Figure 1 The embodiment of the present invention provides a method for monitoring a fuel tank for preventing oil theft in a truck, comprising:

[0033] S100: Acquire the running status of the truck;

[0034] In some implementations, a detection signal of the infrared sensor is acquired in real time;

[0035] determining whether a person is close to the truck fuel tank according to the detection signal of the infrared sensor;

[0036] If it is determined that someone is close to the truck tank, the step of obtaining the real-time liquid level value of the truck tank is started;

[0037] If it is determined that no one is approaching the truck fuel tank, the process returns to the step of determining whether anyone is approaching the truck fuel tank based on the detection signal of the infrared sensor.

[0038] This embodiment also adds an infrared sensor to detect the presence and movement of a human body. The infrared sensor senses the presence and movement of an object by detecting the infrared radiation emitted by the object. Specifically, the infrared sensor works by using the infrared radiation generated by the temperature difference on the surface of the object. As a heat source, the human body emits infrared radiation of a specific wavelength, which can be captured by the infrared sensor and converted into electrical signals, thereby detecting the presence and movement of the human body. When the infrared sensor detects that a human body is approaching, the illegal person may be performing the action of stealing oil, and approaches the oil tank, and further obtains the real-time liquid level value of the oil tank for judgment and processing.

[0039] S200: If it is determined that the running state of the truck is switched to the parking state, an initial liquid level value of the truck fuel tank is detected;

[0040] In some implementations, further comprising:

[0042] Determining whether the truck is located in a key anti-theft area according to the current positioning information;

[0043] If it is determined that the truck is located in a key anti-theft area, the step of controlling the camera device to start is executed, or the step of determining whether a person is close to the truck's fuel tank according to the detection signal of the infrared sensor is executed;

[0045] S300: obtaining a real-time liquid level value of the truck fuel tank, and determining whether the real-time liquid level value is lower than an initial liquid level value;

[0046] The liquid level information of the fuel tank is measured by a liquid level sensor, which can be implemented using an ultrasonic liquid level sensor or a capacitive liquid level sensor. After the liquid level sensor detects that the truck has switched to the parking state, it obtains the liquid level data of the fuel tank in real time.

[0047] S400: If the real-time liquid level value is lower than the initial liquid level value, control a camera device to start, with the camera device shooting towards the oil tank;

[0048] Usually, when the real-time liquid level value is lower than the initial liquid level value, there may be illegal personnel approaching the fuel tank to steal oil. The liquid level sensor maintains real-time detection status all the time, which can immediately trigger the camera equipment to capture the image information at the fuel tank and send it to the control unit for analysis and processing to determine whether there is a human portrait in the image, whether there is any action of stealing oil, etc. The image judgment program is pre-trained into a model and stored in the control unit, which can be retrieved at any time for comparative analysis.

[0049] The camera equipment includes a camera installed at the fuel tank of the truck and front and rear cameras of a driving recorder.

[0050] S500: Determine whether there is a person at the fuel tank of the truck according to the image information captured by the camera device;

[0051] S600: If it is determined that there is someone at the truck fuel tank, an alarm message is sent; if it is determined that there is no one at the truck fuel tank, the initial liquid level value is updated to the currently detected liquid level value.

[0052] Among them, the alarm information can include voice alarm information, light alarm information and text alarm information. Voice and light can have a certain deterrent effect on illegal oil stealers.

[0053] In some implementation modes, before obtaining the running status of the truck, the method further includes:

[0054] Obtain the user's anti-oil theft control instructions;

[0055] If the anti-oil theft control instruction is on, the step of obtaining the running status of the truck is executed; if the anti-oil theft control instruction is off, the step of obtaining the running status of the truck is not executed.

[0056] In some implementations, after sending the alarm information, the method further includes: obtaining the current location of the truck and the truck information, generating the oil theft monitoring point information and uploading it to the anti-theft key area database.

[0060] A judgment module, used to judge whether the real-time liquid level value is lower than the initial liquid level value, and also used to judge whether there is anyone at the truck tank according to the image information taken by the camera device;

[0061] A processing module, configured to control a camera to start if the real-time liquid level value is lower than the initial liquid level value, with the camera facing the oil tank;

[0062] The determination module is used to send an alarm message if it is determined that there is someone at the truck tank; if it is determined that there is no one at the truck tank, the initial liquid level value is updated to the currently detected liquid level value.
