Product Requirement
The equipment is based on the LS400 car air suspension system, fully demonstrating the composition structure and working process of the car air suspension.
Functional Requirements
1. Real and operational automobile air suspension system, fully demonstrate the composition structure of automobile air suspension system.
2. Operate the height control switch or adjust the height of any suspension, the air suspension ECU controls the compressor, height control solenoid valve, suspension shock absorber hardness controller and other executive components to complete the work of the air suspension height and shock absorber hardness The adjustment, a real demonstration of the working process of the car's air suspension system.
3. The measurement panel of the training platform is painted with a color inkjet circuit diagram, which is made of a 5mm thick high-strength transparent acrylic sheet mirrored on the back. It is resistant to large temperature differences, wear-resistant, moisture-proof, corrosion-resistant, not easy to deform, and has a long service life. Bright colors, not easy to fade, etc.; students can intuitively compare the circuit diagram and the real object to understand and analyze the automobile air suspension system
Working principle.
4. There are detection terminals installed on the panel of the training platform, which can directly detect the electrical signals of each circuit element of the air suspension system, such as resistance, voltage, current, frequency signals, etc.
5. The panel of the training platform is equipped with a fault indicator lamp and a diagnosis socket, and the system's self-diagnosis function can be realized by flashing the fault code through the short wire.
6. The training platform is built with international standard aluminum alloy profiles. It has the characteristics of light weight, high strength, corrosion resistance and long life. It does not need to go through the spraying process, is more environmentally friendly, and looks more beautiful and high-end. The bench has self-locking casters. The device is mobile, safe, reliable, sturdy and durable.
7. Multimedia intelligent fault setting and assessment system
1) The system consists of three parts: a tablet equipped with an Android system (Android), a Bluetooth main control board, and a fault setter control board. Teachers can remotely start and stop teaching equipment through the Bluetooth wireless settings that come with the tablet computer. One tablet computer can control multiple teaching equipment, which is convenient for teaching and lectures.
2) The title bar of the assessment fault setting interface uses large fonts to display the name of the teaching equipment, and the name of the fault point is displayed on the fault button in Chinese, which is intuitive and clear. The user can edit and modify the device name and fault point name at will according to different devices, the operation interface is humanized, and the man-machine dialogue is friendly.
3) The Bluetooth of each device is equipped with a different number, which can effectively distinguish multiple devices, and is equipped with Bluetooth connection and Bluetooth disconnection options, which can connect and disconnect the Bluetooth of different devices in one interface, so that teachers can easily control The ignition start and fault settings of all teaching equipment in the classroom are simple and flexible to operate, which effectively improves teaching efficiency.
4) Three types of faults: open circuit, virtual connection, and short circuit can be set. Single fault or multiple faults can be set. Up to 126 faults can be set; there are all settings and all fault clearing functions, which can be used for practical training of students connecting lines operating.
5) There is a teaching mode function. Teachers can save supporting teaching courseware, teaching videos, original car materials, equipment manuals, training manuals and other materials in the teaching mode folder, and wirelessly connect to the projector, LCD TV, and teaching all-in-one machine And so on for multimedia teaching.
6) There is a login interface to distinguish the authority of teachers and students;
7) The software is equipped with an assessment function, which can be assessed by a single machine or by multiple people connected to the Wifi network at the same time. The teacher and the student interface are separated. The teacher can enter by entering the "user name" and "login password". The login password can be changed at will; after the teacher sets the test questions and test time in the "assessment fault setting" interface, send the test questions and enter the assessment mode. Teachers can ask questions at will. After setting the fault, the button on the screen will turn from green to red, and the relay board will act at the same time, and the device will malfunction.
8) The student's grade, class, name, exam number and exam results are recorded in the "student information management" database. Teachers can view student information and exam results at any time, and can be converted into Excel files and exported to software and SD In the card, it is convenient for teachers to manage student information and grades.
9) After starting the server in the "Server Management" interface, you can form a LAN with the student client via Wifi. After the teacher sets the test questions to be sent, the student client interface synchronously displays the name of the test device, the names of all fault points of the device, the category of test questions, and the number of test questions. And the remaining time to answer the question. After the student detects the fault on the device, selects the corresponding fault button, and submits the test paper (or the test time is over), and the test result will be seen, and the software will automatically generate the score report.
10) The software is equipped with a function to limit the number of failures that students can choose, and no more than the number of failures is set to prevent students from random selection.
11) The number of failures of the standard relay control board is 20 open circuits/virtual connections + 6 short circuits. The capacity of each faulty channel is DC10A.
12) A short-circuit fault is a short-circuit of the signal to the ground, and self-recovery insurance is connected in series between the lines to prevent the computer from being damaged by the wrong line connection.
13) RS485 field industrial bus communication is adopted between the Bluetooth main control board and the relay control board, with long communication distance, stable signal and anti-interference.
14) It can be used in conjunction with the touch screen intelligent fault setter, with two operating modes, wireless and wired, which is flexible and convenient.
