Description

A visual electronically controlled engine intelligent diagnosis method, system, device and storage medium Technical Field

[0001] The present invention relates to the technical field of engine diagnosis, and more specifically, to a visual electronically controlled engine intelligent diagnosis method, system, device and storage medium. Background Art

[0002] HMI, short for Human Machine Interface, is a visual interface between humans and machines. It allows users to visualize the machine's operating status (parameters) and issue commands. By combining HMI programs with sophisticated touchscreen technology, users can easily control various machine operations, simplifying previously cumbersome operating procedures. This remarkable invention, a major technological advancement, is now widely used in a wide range of devices.

[0003] Internal combustion engine (hereinafter referred to as engine) technology has been developing for hundreds of years. From its initial purely mechanical structure to today's electronically controlled and intelligent systems, it has increasingly incorporated electronic technologies, significantly improving engine economy, emissions, comfort, and adaptability, pushing engine technology towards a stage of high precision and intelligence. Engine fault self-diagnosis is one of the most obvious signs of the electronic control era. This means that the engine uses digital information to self-diagnose its own faults and displays these information to the operator. The process is shown in Figure 1.

[0004] 1. The engine control system monitors and automatically diagnoses relevant sensors and actuators in real time.

[0005] 2. When a fault is detected, the controller will digitize the fault information and broadcast it to the outside through code.

[0006] 3. Professional maintenance personnel will read the fault code manual or professional tools (communication tools, host computer software) and further analyze the meaning of the fault.

[0007] However, current diagnostic strategies and presentations still have many deficiencies, failing to meet people's pursuit of convenience, timeliness, and intelligence. These deficiencies are mainly reflected in the following aspects:

[0008] 1. Most of the information after the engine self-diagnosis is code information. Only the development engineers can understand the true meaning of the fault by looking up the manual. This is not convenient for ordinary operators to solve the problem on site, and the fault is not solved in a timely manner.

[0009] 2. After finding out the meaning of the fault, it is difficult for ordinary operators to find the specific fault location (parts) because they are not familiar with the engine. Professional technicians are still needed to find it accurately.

[0010] 3. Even if the faulty part (faulty component) is found, ordinary personnel are unable to troubleshoot due to lack of experience.

[0049] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0050] Referring to Figures 2 to 6, a visual intelligent diagnostic method for an electronically controlled engine includes:

[0051] Make a display model of the engine;

[0052] Setting a display label for the part to be diagnosed of the display model. The part to be diagnosed includes each sensor and actuator of the engine. Specifically, the display label is the name of the part to be diagnosed, such as a crankshaft position sensor and a throttle valve.

[0053] Display the display model with set display labels on the HMI, that is, each sensor and actuator can be directly seen on the engine display model, and ordinary operators can understand it at a glance;

[0054] The engine test results are sent to the HMI in real time, and the display labels corresponding to the currently detected parts to be diagnosed are highlighted. For example, the display labels corresponding to the parts to be diagnosed in the current test item are highlighted, and the display labels corresponding to the parts not involved in the diagnosis are grayed out. This is simple and clear, and has better readability.

[0055] The display label will show different states according to the test results, that is, the normal and faulty parts to be diagnosed will be displayed in different colors, so that ordinary operators can better identify the faulty parts (components);

[0056] Based on the test results, the diagnostic database is queried to obtain fault information and troubleshooting measures, which are then displayed on the HMI. The diagnostic database pre-stores diagnostic guidance information for each sensor or actuator, including the fault code, the corresponding fault information, and the troubleshooting measures. This allows operators to quickly grasp fault information and take appropriate troubleshooting measures, thereby maximizing engine protection.

[0057] The display model includes at least one of a front view, a top view, a left view, a right view, a bottom view, a rear view, a perspective view, a real view, and a partially enlarged view of the engine. For example, FIG2 is a left view of the engine, FIG3 is a right view of the engine, and FIG4 is a front view of the engine.

[0058] Specifically, the display model is used as the first layer, the display label is used as the second layer, and the fault information and troubleshooting measures are used as the third layer. The first layer, the second layer, and the third layer are merged and displayed on the HMI. The specified layer can be displayed as needed.

[0059] Set up buttons for switching between different parts to be diagnosed, and display the buttons on the HMI. Click the buttons of different views to switch to different views, or magnified images of the part to be diagnosed, so that diagnosis can be conveniently performed from various views.

[0060] Add a click response to the display label. After clicking the display label, the HMI displays the detailed information of the part to be diagnosed corresponding to the label. The detailed information includes the name of the part to be diagnosed, the current operating status, and the enlarged image of the part to be diagnosed.

[0061] When a fault is detected, the HMI directly jumps to the view of the fault location, and the display label is highlighted, such as by being highlighted or flashing. In this embodiment, the display label is displayed in a flashing red and a red guide light ring appears. For example, the display label surrounded by three circles in Figure 5 is the display label of the current fault alarm, which allows for quick and easy identification of the fault location. Clicking this display label automatically brings up the engine view where the fault location is located, as shown in Figure 6. Using the locking circle as a guide, clicking the corresponding component name will bring up the system's detailed information about the faulty component, along with detailed troubleshooting instructions. This prompt allows for testing and troubleshooting the component.

[0062] A visual electronically controlled engine intelligent diagnostic system, comprising:

[0063] Model making module, used to make the display model of the engine;

[0064] Making a label module for setting display labels on the part to be diagnosed on the display model;

[0065] Display module, used to display the display model with set display labels on the HMI;

[0066] The test result sending module is used to send the engine test results to the HMI in real time, highlight the display label corresponding to the currently detected part to be diagnosed; and display the label in different states according to the test results;

[0067] The fault troubleshooting module is used to query the diagnostic database according to the detection results to obtain fault information and fault troubleshooting measures, and display the fault information and fault troubleshooting measures on the HMI.

[0068] A PLC programmable logic control device includes a memory and a processor. The memory stores a control program. When the processor executes the control program, it receives relevant fault information, stores it, performs calculations and analysis, and outputs execution instructions to implement the above-mentioned visual electronic control engine intelligent diagnosis method.

[0069] A computer-readable storage medium stores a computer program, including a configuration program for an HMI touch screen. When the computer program is executed by a processor, the above-mentioned visual electronically controlled engine intelligent diagnosis method is implemented.

[0070] This invention, based on an embedded development program applied to an HMI touch screen, can display and lock engine faults layer by layer, automatically display the fault location (component) in graphical form, and finally provide a troubleshooting method. This allows ordinary operators to troubleshoot and solve the problem one by one according to the prompts of the fault strategy.

[0071] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
