It is suitable for the teaching needs of school theory and m--ntenance tr--ning for automotive sensor systems.

This equipment meets the teaching needs of "five docking and ten connections" of automobile vocational education.

two. Features

1. Use a complete engine sensor component to use a crankshaft sensor signal wheel to simulate the engine operation;

After the experimental plug -in wire is connected, the working process of the engine sensor and the control unit can be truly demonstrated (such as the action process of the spark plug ignition, the fuel injection, and the fuel pump work.)

2. Install the original car engine control unit, which can move the tablet and multiple sensors.

3. Demonstration of color inkjet circuits on the teaching panel. Students can intuitively control the circuit diagram to connect the sensor to understand and analyze the working principle of the automotive sensor system.

4. Sensors such as fuel tank, fuel volume and other sensors, engine control units, oil pump relay, ignition switch, diagnostic seat, insurance box, and panel are installed on the panel, which can directly detect the engine sensor control system circuit directly on the panel. Essay's telecommunications signal.

5. Detective terminals are installed on the side of the device panel to directly connect the sensor.

6. Install a diagnostic seat on the device, which can be connected to a dedicated or general -purpose car decoder. The engine control unit can perform the ECU encoding query, read the fault code, remove the fault code, read the data flow, execute component test, parameter settings, and the parameter setting. Self -diagnostic functions such as waveform analysis.

7. The equipment panel part uses a 1.5mm cold plate stamping and forming structure, which is beautiful in appearance; the bottom part is welded with steel structure, the surface is treated with spraying process, a self -locking wheel device, and a desktop of about 40cm on the bottom of the teaching board, which is convenient for convenience Place information, light detection instruments, etc.

8. Equipment parts are welded with steel structure, the surface is used to p--nt the p--nt, with a self -locking wheel device, and the movement is flexible.

9. Equipment work adopts a normal 220V AC power supply. The internal circuit transformer is transformed into a 12V DC power supply. Without batteries, it is not necessary to reduce the trouble of charging. The 12V DC power supply has a short -circuit function.

10. Machinery assembly and fitter assembly virtual simulation software: This software is developed based on Unity3D. It can choose 6 -level image quality. It has the design and virtual disassembly of the reducer and shaft structure, the design and simulation of common mechanical institutions, institutional resource libraries, institutional resource libraries. Typical mechanical institutions (virtual disassembly of gasoline engines), software is an overall software, which cannot be separate resources.

Feature

1. The entire device is beautiful and generous, with a reasonable structure design, and has a strong engineering atmosphere, which can fully reflect the concept of modern laboratories;

2. The equipment layout is reasonable, beautiful, the structure is clear, and the overall sense is strong. It can reflect the concept of the m--n experimental equipment in the laboratory.

3. The equipment is a self -propelled frame structure, and the feet are installed to facilitate the disassembly m--ntenance and handling of the system.

4. The flow measurement uses the turbine turbine meter. The data processor has a strong compensation function for the linear coefficient of the turbine flowmeter, and the flow data directly displays the flow data.

5. The centrifugal pump is placed above the water tank. The centrifugal pipe is installed with a bottom valve. At the same time, a centrifugal pump is installed to start the exhaust device to avoid the centrifuge of the centrifugal pump leaf wheel and the cavity soak in the water for a long time, which greatly extend the life of the equipment.

6. The entire system adopts a standard industrial instrument control system, which can perform chemical principles experiments. It is also a good platform for process automation and chemical testing instrument experiments.

7. Device design can be observed at 360 degrees to achieve comprehensive teaching and experiments.

Device function

1. Let students fully understand the structure and characteristics of the centrifugal pump, and be familiar with the working methods and operation processes of centrifugal pumps.

2. Being a single pump, dual pump string parallel operation.

3. Familiar with various pipes and valves that form the pipelines, understand the instrument and sensor detection equipment on the spot, such as temperature, pressure, electrical power, traffic, etc., and master the measurement principles and usage methods of turbine turbines.

4. Measure the pump characteristic curve between the pumps (H), axis power (n), and efficiency (η) and the flow of the pump (q) under constant speed conditions.

5. Determine the characteristic curve of the pipeline under the opening degree of the flow regulating valve.
