Briefly describe the diagram recognition method of automobile circuit diagram

1. Understand the meaning of circuit diagram symbols and lines.The symbols and line types in the automobile circuit diagram need to be familiar, such as battery symbols, voltmeter symbols, switch symbols, fuse symbols, etc. Analyze the structure of the whole circuit diagram.

2. The reading method of the automobile circuit diagram is as follows: the circuit diagram annotation must be read before starting to read the diagram. Clarify the number and function of each electrical component according to the diagram, and find out the current path of each electrical component. When reading pictures, you can do it one by one by segmentation.

3. Follow the current direction from the negative pole to the electrical appliance, and then to the positive pole of the battery. The method of selecting and organizing a path or a combination of two paths is good at simplifying complex system circuits, which is conducive to quickly organizing the circuit structure. Automobile circuit diagram identification steps: Take the Volkswagen/Audi circuit diagram structure that is familiar with the circuit diagram structure and component layout as an example.

Toyota Automobile Circuit Diagram Recognition Method

1. The meaning of each part of the Toyota Automobile Circuit Diagram is as follows: A indicates the title symbol of each subsystem. B indicates the wiring color. For example, the color number of the wire in the circuit diagram is R, indicating that the color of the wire is red in the actual circuit.

2. The wiring diagram mainly shows the position of parts in the car, generally including the engine compartment, dashboard, body, electric seats and other parts. In addition, the wiring diagram also includes the wiring connector, the connection point and the hinge junction location diagram. The wiring connector is used to connect the circuit between the components and the wiring.

3. The point-by-point grounding detection method can confirm the open circuit position, and the sequential disconnection detection can confirm the short-circuit grounding position. ExamineThe order can be from front to back, from back to front, or from the middle to both sides. Each node can be selected in turn, mainly divided into two lines. Start the control circuit, mainly to detect the on-off of the circuit.

4. The reading method of automobile circuit diagrams is as follows: understand the meaning of circuit diagram symbols and lines. The symbols and line types in the automobile circuit diagram need to be familiar, such as battery symbols, voltmeter symbols, switch symbols, fuse symbols, etc. Analyze the structure of the whole circuit diagram.

What software can see pictures to recognize cars

Software I: AI Recognition King APP This is a powerful mobile phone application, which can scan the car An interior picture to quickly identify the car model. In addition, this application can also provide detailed information about the vehicle, such as the year of production of the vehicle, basic configuration, model characteristics, etc.

The software for looking at pictures to recognize cars is as follows: Auto Home. From knowing and choosing a car to buying and changing a car, this software can provide you with super professional help in answering questions. By taking photos, you can quickly identify vehicles for you with one click, and through many sharing comments, you can truly understand various information and word of mouth."Easy Car".

The software for watching cars include: Auto Home, Buy Car Treasure, Car Quotation Collection, Easy Car, Pacific Automobile Network, etc. Software (mainland China and Hong Kong terms, called software in Taiwan, English: Software) is a collection of computer data and instructions organized in a specific order.

As long as the user enters the characteristics of the car he wants to query, the Autohome app can help users quickly identify the model, analyze the model structure and other functions.

The most common software to identify models is Huawei mobile phone browser's graphic recognition, or WeChat applet. In traffic security, model recognition is an important technical point. Model identification mainly includes vehicle detection, model recognition, color recognition, video-based model recognition, and the design of tracking algorithms.

What are the common methods of car picture recognition?

(3) Be familiar with the wiring and color markings of the line. ( 4) Be familiar with the function of the control. ( 5) Remember the circuit principle and the iron polarity. ( 6) Understand the working status of the relay. ( 7) Achieve contact bypass by dissecting typical circuits.

Through the analysis of typical circuits, contact bypass is achieved. Many parts of the circuit schematics of many models are similar or similar. In this way, through a specific example, give one and reverse three, compare, and touch and bypass.

Analyze according to the flow of the circuit. Guide the target from the power supply, and conduct circuit analysis according to the flow of the circuit. For example, observe the whole circuit first.Whether it is energized, whether there is a normal output of voltage, and ensure that the path from the power supply to the receiving end of the circuit is continuous.

The letters in the circuit diagram are annotation labels, and the meanings of each part are as follows: annotation label A: indicating the title of the system, which is divided by horizontal lines above the circuit diagram, and the name of the circuit system below is represented by text and system symbols in the area. Note B: Indicates the relay box, which is only distinguished from the junction box by the relay number, and there is no shadow.

Auto parts drawing recognition requires those tools

1, 1 wrench (movable, opening, plum blossom, inner corner, torsion, pulling horse, etc.), 2 starting tools (word, cross, electric drill, etc.), 3 pliers (vise, drill clip Head, V-shaped iron, etc.) fixtures: These are not technically classified.

2. VX series flash detector VX series flash detector is a typical application in the auto parts industry.

3. Production tools are used to make simple parts: drawing tools; filing tools; cutting tools; shoveling tools; grinding tools; straightening and bending tools.

4. Oscilloscope Oscilloscope is mainly used to trigger and collect signals (waveforms), scale and locate waveforms, measure waveforms, etc. In automobile maintenance, it is very useful for detecting ignition systems, exhaust emission analysis and parts quality.

5. Automotive testing instruments: such as dynamic chassis testing machine, emission gas analyzer, fault self-diagnosis instrument, etc. These instruments are mainly used to test automobile performance and fault diagnosis. Precision measuring tools: such as micrometers, calipers, scales, etc.These tools are mainly used to measure the appearance and structure of vehicles.

6. In-line inspection: speed table, exhaust gas meter, smoke meter, opaque light meter, axle weight table, brake table, light meter, side slide table. There is also a sound level meter in the commercial inspection. Off-line inspection: tire pattern depth ruler, light transmittance meter, etc. are required.
