Description

Technical Field

[0001] The present invention relates to the field of fuel vehicle oil circuit systems, and in particular to an alarm method, device and storage medium for abnormal fuel consumption. Background Art

[0002] The oil system of a car, also known as the fuel system, is a series of components and pipelines responsible for delivering fuel to the engine. Its basic function is to provide an appropriate amount of clean, well-atomized fuel according to the working requirements of the engine, and mix it with air to form a combustible mixture to maintain the normal operation of the engine. If the fuel tank is damaged by external forces, resulting in oil leakage or oil theft, at least the following hazards are involved: affecting vehicle performance, environmental pollution, safety hazards, causing economic losses, etc.

[0003] In the prior art, patent CN202022793043.3 discloses a fuel vehicle anti-leakage system, and discloses that the system includes an oil quantity collection module, a signal processing module, a control module, an alarm module and a power module. Among them, the oil quantity collection module is used to collect the oil quantity change signal of the vehicle tank, the signal processing module is used to process the received electrical signal to obtain a digital signal, the control module is used to analyze and process the received digital signal, and control the working state of the alarm module; the alarm module is used to send an alarm signal to remind the user that the fuel consumption speed in the vehicle is abnormal. In the technical solution disclosed in the above patent, the oil quantity detection of fuel vehicles is always consistent. That is to say, under various working conditions, the detection standard for whether the fuel vehicle is leaking oil is unchanged. However, in reality, since the vehicle may be in different working conditions, for example, it may be in a starting state or a stopping state, the starting state also has a standard mode, an off-road mode, a snow mode, etc. For different working conditions, the oil consumption of fuel vehicles varies greatly. Therefore, the detection method for abnormal fuel consumption or oil leakage in the prior art is single, and it is impossible to distinguish different working conditions for targeted detection.

[0044] The execution subject of the abnormal fuel consumption alarm method provided in the embodiment of the present invention is an abnormal fuel consumption alarm method device. The abnormal fuel consumption alarm method device can be a computer device, which can be an electronic device or a server, or a central processing unit (CPU) in the electronic device or server.

[0045] Figure 1A schematic diagram of the composition of an abnormal fuel consumption alarm device provided by an embodiment of the present invention. Figure 1 As shown, the abnormal fuel consumption alarm device may include: at least one processor 11, a memory 12, a communication interface 13 and a communication bus 14.

[0046] The processor 11 is the control center of the abnormal fuel consumption alarm device, which may be a CPU, a microprocessing unit, or one or more integrated circuits for controlling the execution of the program of the embodiment of the present invention.

[0047] As an embodiment, the processor 11 may include one or more CPUs, such as Figure 1 Furthermore, as an embodiment, the alarm device for abnormal fuel consumption may include multiple processors, such as Figure 1 The processor 11 and the processor 15 shown in FIG. Each of these processors can be a single-core processor (Single-CPU) or a multi-core processor (Multi-CPU).

[0048] The memory 12 may be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical disc, laser disc, optical disc, digital versatile disc, Blu-ray disc, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory 12 may exist independently and be connected to the processor 11 via the communication bus 14. The memory 12 may also be integrated with the processor 11.

[0049] In a specific implementation, the memory 12 is used to store the data of the present invention and execute the software program of the present invention. The processor 11 can execute various functions of the alarm device for abnormal fuel consumption by running or executing the software program stored in the memory 12 and calling the data stored in the memory 12.

[0050] The communication interface 13 uses any transceiver or other device for communicating with other devices or communication networks, such as a radio access network (RAN), a wireless local area network (WLAN), etc. The communication interface 13 may include a receiving unit to implement a receiving function, and a sending unit to implement a sending function.

[0051] The communication bus 14 may include a pathway for transmitting information between the above-mentioned components.

[0052] It should be pointed out that Figure 1 The structure shown in the figure does not constitute a limitation on the alarm device for abnormal fuel consumption, except Figure 1 In addition to the components shown, the abnormal fuel consumption alarm device may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

[0053] Based on the above description of the structure of the alarm device for abnormal fuel consumption, an embodiment of the present invention provides an alarm method for abnormal fuel consumption. Figure 2 As shown, the alarm method for abnormal fuel consumption may include the following S1-S5:

[0054] S1, the signal receiving module 10 obtains the resistance signal provided by the acquisition device 200;

[0055] It should be noted that the signal receiving module 10 included in the alarm device 100 for abnormal fuel consumption continuously and in real time obtains the resistance signal. The resistance signal here is provided by the acquisition device 200. Figure 4 As shown, the collection device 200 includes an oil float 21 and a fuel level sensor 22 arranged in the fuel tank. The oil float 21 is usually made of a material with a density less than that of the fuel to be measured, such as plastic or foam. When the oil float 21 is immersed in the fuel, according to the Archimedes principle, the buoyancy of the oil float 21 is related to the density of the fuel to be measured and the depth of immersion. The immersion depth of the oil float 21 changes with the change of the liquid level, so the height of the liquid level can be determined by measuring the immersion depth of the oil float 21. Further, the wire 23 connects the oil float 21 and the fuel level sensor 22. The wire 23 usually has a certain rigidity and flexibility, which can ensure that the movement of the oil float 21 is not disturbed by the outside world. The length of the wire 23 is usually determined according to the height of the liquid level. When the immersion depth of the oil float 21 changes, the wire 23 will expand and contract accordingly, thereby transmitting the liquid level information to the fuel level sensor 22. The fuel level sensor 22 receives the signal transmitted by the wire and converts it into an electrical signal for output. The fuel level sensor 22 usually uses a pressure sensor or a displacement sensor to determine the height of the liquid level by measuring the expansion and contraction of the wire 23, and converts it into a corresponding electrical signal for output.

[0056] Specifically, referring to Table 1, a comparison table of the fuel volume in the fuel tank and the output resistance value is provided in an embodiment:

[0057] Table 1

[0058]

[0059] It should be noted that the volume of the fuel tank is different in different application scenarios. Under the same fuel consumption, the "taller and thinner" the fuel tank is, the faster the fuel level drops, and the faster the output resistance signal changes. Conversely, the "shorter and fatter" the fuel tank is, the slower the fuel level drops, and the fuller the output resistance signal changes. However, no matter what the shape of the fuel tank is, for the same fuel tank, the output resistance signal and the fuel volume of the tank must correspond one to one. Therefore, when the alarm device for abnormal fuel consumption obtains the resistance signal, it can correspond to the fuel volume in the tank at that moment. If the fuel is consumed abnormally, such as leaking or being stolen, the change in the fuel volume in the tank will also correspond to the change in the output resistance signal.

[0060] S2. The data analysis module 20 determines the change rates of a plurality of resistance signals within a preset time period according to a preset algorithm.

[0061] It is understandable that the data analysis module 20 calculates the acquired resistance signal according to a preset algorithm to obtain the change rate of the resistance signal. Exemplarily, the change rate is calculated as follows:

[0062]

[0063] Among them, α is used to represent the rate of change;

[0064] R1, used to indicate the resistance value of the resistance signal at the first time;

[0065] R2, used to indicate the resistance value of the resistance signal at the second time;

[0066] T1, used to indicate the first time;

[0067] T2 is used to indicate the second time.

[0068] S3. The engine state determination module 30 determines the engine state.

[0069] It should be noted that the embodiments of the present invention have different conditions for judging abnormal fuel consumption for different engine operating conditions. Therefore, after obtaining the rate of change of the resistance signal and before judging whether the fuel is abnormally consumed, it is necessary to determine the engine state. Specifically, the engine includes two states: start and shut down. The engine state determination module 30 obtains the engine speed signal; if the speed signal is not equal to zero, it is determined that the engine is in the start position; if the speed signal is equal to zero, it is determined that the engine is in the shut down position. The engine state is determined by obtaining the engine speed signal.

[0070] It should be noted that after executing S3, the engine state determination module 30 determines the engine state and then selects to execute S41 or S24 according to the determined engine state.

[0071] Specifically: S41, when the engine is in the start position, if the change rate is not less than the first preset threshold, the fuel abnormality determination module 40 determines that the fuel consumption is abnormal.

[0072] It is understandable that when the engine is in the starting position, it should have a normal fuel consumption range according to the intensity of the engine's work. Therefore, if the change rate of the resistance signal is not less than the first preset threshold, the fuel abnormality determination module 40 determines that the fuel consumption is abnormal. It should be noted that the first preset threshold must be greater than the change rate of the resistance signal caused by the fuel consumption under normal engine conditions. Exemplarily, the first preset threshold is not less than 1.5 times the change rate of the resistance signal of the engine under the maximum fuel consumption condition. It is understandable that the fuel consumption rate refers to the fuel consumption of the engine working at a power of one kilowatt for one hour, also known as the automobile brake fuel consumption rate. The maximum fuel consumption rate is the fuel consumption rate of the engine under the maximum fuel consumption condition. The maximum fuel consumption rate is determined by the engine calibration characteristics and is a fixed value. As mentioned above, it can be seen that the change rate of the resistance signal of the engine under the maximum fuel consumption condition is also a fixed value. Therefore, when the first preset threshold is not less than 1.5 times the change rate of the resistance signal of the engine under the maximum fuel consumption condition, if the change rate is not less than the first preset threshold, the fuel consumption is determined to be abnormal. It can be understood that the change rate of the resistance signal is not less than 1.5 times the change rate of the resistance signal when the engine is in the maximum fuel consumption condition. The change rate of the resistance signal is obviously higher than the normal level. Therefore, it can be determined that the oil is consumed abnormally at this time.

[0073] In an optional embodiment, the rate of change of the resistance signal of the engine when the engine is in the maximum fuel consumption condition is 2Ω / s-3Ω / s; the first preset threshold is 3Ω / s-4.5Ω / s. It is understandable that if the rate of change of the resistance signal of the engine when the engine is in the maximum fuel consumption condition is 2Ω / s, and the fuel abnormality determination module 40 determines that the rate of change of the resistance signal within a preset time period is not less than 3Ω / s, then it is considered that the fuel level in the fuel tank at this time drops too fast, which is abnormal fuel consumption. Similarly, if the rate of change of the resistance signal of the engine when the engine is in the maximum fuel consumption condition is 3Ω / s, and the fuel abnormality determination module 40 determines that the rate of change of the resistance signal within a preset time period is not less than 4.5Ω / s, then it is considered that the fuel level in the fuel tank at this time drops too fast, which is abnormal fuel consumption. In addition, the correspondence between the resistance signal change rate and the first preset threshold value when the engine is under maximum fuel consumption conditions can also be 2.5Ω / s and 3.75Ω / s, 3.5Ω / s and 5.25Ω / s, 4Ω / s and 6Ω / s, etc., which can be determined according to the actual application scenario.

[0074] S42, when the engine is in the off position, if the change rate is not less than the second preset threshold, the fuel abnormality determination module 40 determines that the fuel consumption is abnormal;

[0075] It is understandable that when the engine is in the off position, the fuel consumption is necessarily less than when the engine is in the on position. Therefore, the second preset threshold is less than the first preset threshold.

[0076] It should be noted that the determination of the first preset threshold and the second preset threshold should be determined according to the actual application scenario of the alarm device for abnormal fuel consumption. This embodiment only provides a possible implementation method and does not constitute a limitation thereto.

[0077] It can be understood that determining whether the fuel is consumed abnormally by the change rate of the resistance signal avoids the need to convert the resistance change into the fuel volume change in the prior art, saves execution steps, and is more intuitive and convenient.

[0078] In an embodiment of the present invention, the engine state determination module determines the engine state, specifically, whether the engine is in the start position or the shutdown position, compares different thresholds on the rate of change of the resistance signal, and determines whether the fuel consumption is abnormal when the engine is started and shut down. The embodiment of the present invention is not limited to the engine only including these two working conditions. Exemplarily, when the engine is in the start position, it can also include an economy mode, a sports mode, an off-road mode, a snow mode, and the like. The engine has different working conditions for different driving modes selected for fuel vehicles. Different threshold settings for the rate of change of the resistance signal can be made according to different working conditions. Under this working condition, the rate of change of the resistance signal is not less than the specified threshold to determine abnormal fuel consumption. Compared with the prior art, the judgment of abnormal fuel consumption is more accurate.

[0079] S5. The alarm module 50 sends an alarm signal to the user.

[0080] It is understandable that if the rate of change is not less than the first preset threshold when the engine is in the start position; or if the rate of change is not less than the second preset threshold when the engine is in the shutdown position, the fuel consumption at this time is determined to be abnormal, and the fuel abnormality determination module 40 sends an alarm signal to the user. Specifically, the fuel abnormality determination module 40 sends an alarm signal to the display screen to prompt the abnormal phenomenon and conduct a timely inspection. At the same time, in order to avoid the driver not being able to obtain the alarm information in time when he is not in the vehicle. The fuel abnormality determination module 40 also sends an alarm signal to the user terminal that can communicate, and promptly warns of the abnormal fuel consumption phenomenon.

[0081] Exemplarily, if the change rate is not less than the first preset threshold when the engine is in the start position, an "abnormal fuel consumption" alarm signal is sent to the display screen and the user terminal; if the engine is in the shutdown position, the change rate is not less than the second preset threshold, a "fuel leakage" alarm signal is sent to the display screen and the user terminal.

[0082] The embodiment provided by the present invention obtains the resistance signal in real time, calculates the resistance signal, and determines its rate of change. Under different working conditions of the engine, the rate of change is compared with different preset thresholds, so as to more accurately determine whether the fuel is consumed abnormally. If abnormal fuel consumption is determined, an alarm is sent to the display screen and the user terminal, and maintenance is carried out in time to avoid damage to the fuel tank or expansion of losses, thereby improving the safety of the fuel tank and the vehicle.

[0083] The above mainly introduces the solution provided by the embodiment of the present invention from the perspective of the device. It is understandable that in order to realize the above functions, the device includes a hardware structure and / or software module corresponding to each function. Those skilled in the art should easily realize that, in combination with the algorithm steps of each example described in the embodiment disclosed in this article, the present invention can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present invention.
