[0034] Figure 4 This is a schematic diagram of the structure of an electronic device provided according to an embodiment of this application. Detailed Implementation

[0035] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0036] The following description, with reference to the accompanying drawings, outlines a method, apparatus, device, and medium for early warning of engine cylinder head gasket displacement according to embodiments of this application. Addressing the issue mentioned in the background section that related technologies can only detect cylinder head gasket leaks by observing the continuity of bubbles emitted from the vent pipe in the water tank, failing to predict gasket leaks in advance, thus reducing the real-time performance and reliability of cylinder head gasket fault detection and shortening engine lifespan, this application provides an early warning method for engine cylinder head gasket displacement. In this method, the target displacement corresponding to the target pressure borne by the engine cylinder head gasket strip can be determined. If the target pressure exceeds a preset pressure value or the target displacement exceeds a preset displacement, an early warning reminder for engine cylinder head gasket displacement is generated, effectively predicting cylinder head gasket leaks in advance and improving the real-time performance and reliability of cylinder head gasket fault detection. This solves the problem in related technologies where early prediction of cylinder head gasket leaks is impossible, reducing the real-time performance and reliability of cylinder head gasket fault detection and shortening engine lifespan.

[0037] like Figure 1 As shown in the embodiment of this application, an early warning system for displacement of engine cylinder head gasket strip is established. The system includes an upper plate 1, a middle plate 2, a lower plate 3, a frame 4, a cylinder block 5, a cylinder head 6, a sealing rubber 7, a pressure sensor 8, a laser displacement sensor 9, and a data acquisition unit 10.

[0038] The cylinder head gasket consists of an upper plate 1, a middle plate 2, a lower plate 3, a frame 4, and a sealing rubber 7. The cylinder head gasket is installed between the cylinder block 5 and the cylinder head 6. A pressure sensor 8, a laser displacement sensor 9, and a data acquisition system 10 are used to acquire data. In this embodiment, the pressure sensor 8 and the laser displacement sensor 9 are installed on the sealing rubber 7. The measured data is transmitted wirelessly to the data acquisition system 10, which can monitor the pressure and displacement of the sealing rubber 7 in real time. When the pressure on the cylinder head gasket is too high, or the displacement of the sealing rubber 7 exceeds the limit, an early warning can be given to prevent leakage.

[0039] Specifically, Figure 2 This is a flowchart illustrating a method for early warning of displacement of the engine cylinder head gasket strip, provided in an embodiment of this application.

[0040] like Figure 2 As shown, the early warning method for displacement of the engine cylinder head gasket includes the following steps:

[0041] In step S201, the target pressure borne by the cylinder head gasket strip of the engine is detected.

[0042] It is understood that the embodiments of this application can detect the target pressure borne by the cylinder head gasket strip of the engine. For example, the embodiments of this application can detect the pressure borne by the cylinder head gasket strip of the engine through the pressure sensor in the above system, which effectively improves the feasibility of detecting the displacement of the cylinder head gasket strip of the engine.

[0043] In one embodiment of this application, detecting the target pressure borne by the cylinder head gasket strip of the engine includes: when the engine is in a target heated state, collecting the first pressure of the cylinder head gasket strip generated by the expansion of the engine block; and when the engine is in a target cooled state, collecting the second pressure of the cylinder head gasket strip generated by the contraction of the engine block.

[0044] For example, when the engine is heated during operation, the cylinder block and cylinder head of the above system expand, compressing the cylinder head gasket. The pressure of the cylinder head gasket rubber strip generated by the expansion of the engine cylinder block can be collected by a pressure sensor. When the engine is cooled and contracts, the pressure on the cylinder head gasket decreases. The pressure of the cylinder head gasket rubber strip generated by the contraction of the engine cylinder block can be collected by a pressure sensor, effectively improving the real-time and comprehensiveness of the detection.

[0045] In step S202, the target displacement of the cylinder head gasket strip corresponding to the target pressure is determined.

[0046] It is understood that the embodiments of this application can determine the target displacement of the cylinder head gasket strip corresponding to the target pressure, and can determine whether the engine will leak based on the pressure or displacement. Corrections can be made in advance before engine leakage occurs to improve engine performance.

[0047] Optionally, in one embodiment of this application, determining the target displacement of the cylinder head gasket strip corresponding to the target pressure includes: determining the expansion displacement of the cylinder head gasket frame of the engine based on a first pressure; determining the contraction displacement of the cylinder head gasket frame based on a second pressure; and determining the target displacement of the cylinder head gasket strip using the expansion displacement and contraction displacement.

[0048] For example, when the engine is heated during operation, the cylinder block and cylinder head of the above system expand, compressing the cylinder head gasket. The cylinder head gasket frame expands and displaces outward, causing the sealing rubber to move outward as well. When the engine cools and contracts, the pressure on the cylinder head gasket decreases, and the frame contracts. Since the contraction forces of the sealing rubber and the frame are different, the sealing rubber cannot return to its original position, causing it to gradually shift outward, ultimately leading to engine leakage and affecting engine performance. Therefore, the embodiments of this application can use the laser displacement sensor of the above system to obtain the displacement of the cylinder head gasket strip in real time, thereby improving the real-time performance and accuracy of cylinder head gasket displacement detection.

[0049] In step S203, when the target pressure is greater than the preset pressure value or the target displacement is greater than the preset displacement, a warning reminder for the displacement of the engine cylinder head gasket is generated.

[0050] It is understood that the embodiments of this application can determine the risk of engine leakage when the target pressure is greater than a certain pressure value or the target displacement is greater than a certain displacement. This allows for the timely generation of an early warning reminder for engine cylinder head gasket displacement, prompting relevant technicians to make timely corrections, thereby improving the real-time performance and accuracy of engine detection.

[0051] It should be noted that the preset pressure value and preset displacement can be set by those skilled in the art, and no specific limitations are made here.

[0052] Optionally, in one embodiment of this application, generating a warning reminder for engine cylinder head gasket displacement includes: determining the displacement level of the engine cylinder head gasket based on the target pressure and target displacement; matching the displacement reminder method of the engine cylinder head gasket based on the displacement level, wherein the displacement reminder method includes a voice reminder method and / or a pop-up screen reminder method.

[0053] In this embodiment of the application, the displacement level of the cylinder head gasket strip can be determined according to the target pressure and target displacement. For example, the displacement of the cylinder head gasket strip can be divided into three levels: Level 1 is slight displacement, Level 2 is moderate displacement, and Level 3 is severe displacement. When there is severe displacement, the position of the cylinder head gasket strip needs to be corrected in time to prevent leakage.

[0054] For example, when the displacement level of the engine cylinder head gasket is determined to be Level 1 based on pressure and displacement, this embodiment of the application can display a message on the vehicle's display screen to inform the user that the cylinder head gasket has slightly shifted; when the displacement level of the engine cylinder head gasket is Level 3, this embodiment of the application immediately plays a voice prompt through the vehicle's audio system and displays a displacement warning message on the display screen. In addition, if the user has set up to send reminders to a smartphone or tablet, a reminder notification will also be sent to the smartphone or tablet so that the user can perform engine maintenance in a timely manner and extend the engine's service life.

[0055] Optionally, in one embodiment of this application, after generating a warning reminder of engine cylinder head gasket displacement, the method further includes: generating a cylinder head gasket displacement report based on the first and second displacements of the cylinder head gasket; and sending the displacement report to a preset terminal to display the displacement report to the user on the preset terminal.

[0056] For example, in this embodiment of the application, a detailed displacement report can be generated based on the first displacement data and the second displacement data of the cylinder head gasket strip detected by the laser displacement sensor. The report is then sent to the engineer's laptop computer, which has a dedicated application for viewing calibration reports. The engineer can open the application and see detailed calibration results, including charts, text descriptions, etc. If there are any results that do not meet the standards, the report will also clearly point them out and provide correction suggestions, effectively improving the intelligence of the engine cylinder head gasket strip displacement warning.

[0057] The engine cylinder head gasket displacement early warning method proposed in this application can determine the target displacement corresponding to the target pressure borne by the engine cylinder head gasket strip. When the target pressure exceeds a preset pressure value or the target displacement exceeds a preset displacement, an early warning reminder for engine cylinder head gasket displacement is generated. This effectively predicts cylinder head gasket leakage in advance, improving the real-time performance and reliability of cylinder head gasket fault detection. Therefore, it solves the problem in related technologies where cylinder head gasket leakage cannot be predicted in advance, reducing the real-time performance and reliability of cylinder head gasket fault detection and shortening engine lifespan.

[0058] Next, referring to the accompanying drawings, a warning device for engine cylinder head gasket displacement according to an embodiment of this application is described.

[0059] Figure 3 This is a block diagram of an engine cylinder head gasket displacement warning device according to an embodiment of this application.

[0060] like Figure 3 As shown, the engine cylinder head gasket displacement warning device 10 includes: a detection module 100, a determination module 200, and a warning module 300.

[0061] Specifically, the detection module 100 is used to detect the target pressure borne by the cylinder head gasket strip of the engine.

[0062] The determination module 200 is used to determine the target displacement of the cylinder head gasket strip corresponding to the target pressure.

[0063] The early warning module 300 is used to generate an early warning reminder of engine cylinder head gasket displacement when the target pressure is greater than the preset pressure value or the target displacement is greater than the preset displacement.

[0064] Optionally, in one embodiment of this application, the detection module 100 includes: a first acquisition unit and a second acquisition unit.

[0065] The first acquisition unit is used to acquire the first pressure of the cylinder head gasket generated by the expansion of the engine block when the engine is in a target heated state.

[0066] The second acquisition unit is used to acquire the second pressure of the cylinder head gasket generated by the contraction of the engine block when the engine is in a target cooling state.

[0067] Optionally, in one embodiment of this application, the determining module 200 includes: a first determining unit, a second determining unit, and a third determining unit.

[0068] The first determining unit is used to determine the expansion displacement of the cylinder head gasket frame of the engine based on the first pressure.

[0069] The second determining unit is used to determine the contraction displacement of the cylinder head gasket skeleton based on the second pressure.

[0070] The third determining unit is used to determine the target displacement of the cylinder head gasket strip using expansion displacement and contraction displacement.

[0071] Optionally, in one embodiment of this application, the warning module 300 includes: a fourth determining unit and a reminder unit.

[0072] The fourth determining unit is used to determine the displacement level of the engine cylinder head gasket strip based on the target pressure and target displacement.

[0073] The reminder unit is used to match the displacement reminder method of the engine cylinder head gasket strip according to the displacement level. The displacement reminder method includes voice reminder and / or pop-up screen reminder.

[0074] Optionally, in one embodiment of this application, the apparatus 10 of this application embodiment further includes: a generation module and a sending module.

[0075] The generation module is used to generate a cylinder head gasket displacement report based on the first and second displacements of the cylinder head gasket after generating a warning reminder of the displacement of the engine cylinder head gasket.

[0076] The sending module is used to send a displacement report to a preset terminal after generating a warning reminder of engine cylinder head gasket displacement, so that the displacement report can be displayed to the user on the preset terminal.

[0077] It should be noted that the explanation of the aforementioned method embodiment for warning of engine cylinder head gasket displacement also applies to the warning device for engine cylinder head gasket displacement in this embodiment, and will not be repeated here.

[0078] The engine cylinder head gasket displacement early warning device proposed in this application can determine the target displacement corresponding to the target pressure borne by the engine cylinder head gasket strip. When the target pressure exceeds a preset pressure value or the target displacement exceeds a preset displacement, an early warning reminder for engine cylinder head gasket displacement is generated. This effectively predicts cylinder head gasket leakage in advance, improving the real-time performance and reliability of cylinder head gasket fault detection. Therefore, it solves the problem in related technologies where cylinder head gasket leakage cannot be predicted in advance, reducing the real-time performance and reliability of cylinder head gasket fault detection and shortening engine lifespan.
