Description

A visual intelligent diagnostic method, system, device, and storage medium for electronically controlled engines. Technical Field

[0001] This invention relates to the field of engine diagnostic technology, and more specifically, to a visual intelligent diagnostic method, system, device, and storage medium for electronically controlled engines. Background Technology

[0002] HMI, short for Human Machine Interface, is simply a visual interactive interface between humans and machines. People can intuitively see the machine's operating status (parameters) and issue commands through the interface. With HMI software and the currently mature touchscreen technology, people can easily perform various control operations on machines, simplifying previously cumbersome procedures. It is a great invention in the history of human technological development and is widely used in various devices.

[0003] Internal combustion engine (hereinafter referred to as engine) technology has been developing for over a century, evolving from the 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, propelling engine technology into a stage of high precision and intelligence. Engine fault self-diagnosis is one of the most obvious characteristics of engine technology entering the electronic control era. This involves the engine using digital information to self-diagnose its own faults and display the fault information to the operator, as shown in Figure 1.

[0004] 1. The engine control system performs real-time monitoring and automatic diagnosis of relevant sensors and actuators.

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

[0006] 3. The fault codes should be read and their meanings further analyzed by professional maintenance personnel using fault code manuals or professional tools (communication tools, host computer software).

[0007] However, current diagnostic strategies and presentation methods still have many shortcomings and cannot meet people's pursuit of convenience, timeliness, and intelligence. These shortcomings are mainly reflected in the following aspects:

[0008] 1. Most of the information after engine self-diagnosis is code information. Only the engineers who developed it can interpret the true meaning of the fault by referring to the manual. This makes it inconvenient for ordinary operators to solve the problem on-site, and the problem-solving is not timely and lacks efficiency.

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

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

[0011] Summary of the Invention

[0012] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art. The purpose of the present invention is to provide a visual intelligent diagnostic method for electronically controlled engines.

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

[0050] Referring to Figures 2 to 6, a visualized intelligent diagnostic method for electronically controlled engines includes:

[0051] Create a display model of the engine;

[0052] Set display labels for the parts to be diagnosed in the display model. The parts to be diagnosed include each sensor and actuator of the engine. Specifically, the display label is the name of the part to be diagnosed, such as crankshaft position sensor or throttle valve.

[0053] The display model with the display labels set is displayed on the HMI, so that all sensors and actuators can be seen directly on the engine display model, which can be understood at a glance by ordinary operators;

[0054] The engine test results are sent to the HMI in real time, and the display labels corresponding to the currently detected diagnostic parts are highlighted. For example, the display labels corresponding to the diagnostic parts of the current test items are highlighted, while the display labels corresponding to the diagnostic parts that are not covered are grayed out, which is simple, clear and easier to read.

[0055] Based on the test results, the display label will show different statuses. 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] The diagnostic database is queried based on the test results 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 fault codes, corresponding fault information, and troubleshooting measures. Ordinary operators can quickly grasp the fault information and take appropriate troubleshooting measures in a timely manner, thereby maximizing engine protection.

[0057] The displayed model includes at least one of the following: front view, top view, left view, right view, bottom view, rear view, perspective view, physical object view, and enlarged partial view of the engine. Figure 2 shows the left view of the engine, Figure 3 shows the right view of the engine, and Figure 4 shows the front view of the engine.

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

[0059] Set up buttons to switch between different diagnostic sites and display the buttons on the HMI. Clicking the buttons for different views allows you to switch to different views or zoom in on the diagnostic site, making it convenient to diagnose from various views.

[0060] Add a click response to the display label. After clicking the display label, the HMI will display detailed information about the area to be diagnosed corresponding to that label. The detailed information includes the name of the area to be diagnosed, the current running status, and a magnified view of the area to be diagnosed.

[0061] When the detection result indicates a fault, the HMI directly jumps to the view of the faulty part, and the display label is highlighted, such as by brightening or flashing. In this embodiment, the display label is displayed as a flashing red color with a red guide circle. As shown in Figure 5, the display label surrounded by three circles is the label of the currently occurring fault alarm, which can easily and quickly locate the faulty part. Clicking on the display label can also automatically bring up the engine view where the faulty part is located, as shown in Figure 6. That is, by using the lock circle guide, clicking on the corresponding component name will bring up the specific information of the faulty component and provide detailed troubleshooting methods. The prompts can be used to test and troubleshoot the component.

[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 diagnostic part, and display different statuses of the display label according to the test results;

[0067] The fault diagnosis module is used to query the diagnostic database based on the test results to obtain fault information and fault diagnosis measures, and then display the fault information and fault diagnosis measures on the HMI.

[0068] A PLC programmable logic control device includes a memory and a processor. The memory stores a control program, and when the processor executes the control program, it receives relevant fault information, stores it, performs calculations and analyses, and outputs execution instructions to realize the above-mentioned visualized intelligent diagnostic method for electronically controlled engines.

It allows ordinary operators to troubleshoot and resolve issues step-by-step based on the fault strategy prompts.

[0071] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention, and these will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
