Yl-211a intelligent open electronic assessment platform
Equipment appearance diagram
Training platform panel
YL – 211 – a type of open mode of electronic practice platform contains various types of high quality power supply, signal source, electric power independently, and each type of measuring instrument and so on, at the same time practice platform for intelligent control system configuration, can complete the user authentication to upload, wrong operation records protection, smart meter reading data to upload, and other functions.Can complete the small and medium-sized electronics training, electronic components, identification and detection, circuit board welding, electronics assembly, electronic products, such as debugging and maintenance training, causes the student to master the basic skills of electronics assembly and debugging, and can meet the electronic production, electronic design competition, curriculum design, graduation design and so on comprehensive, design, innovative training requirements.It is suitable for the practical teaching of the course of electronic technology in various vocational colleges and universities.
Structure and configuration
The training platform should be composed of sheet metal box, power station, misoperation statistics and upper computer control system, and video recording system.
1. Sheet metal box body: the overall material of the training platform is high-strength gray sheet metal shell, with insulation protection at each contact slot and screen printing to clearly show each function.
2. power station: from 4 AC220V power supply, 4 network interfaces, a group of adjustable ac power supply, fixed dc stabilized power supply, a group of adjustable dc power supply, a constant current source output, two voltmeters, two ammeter and frequency meter function signal generator.The device USES single-phase power supply, and is equipped with air switch with leakage protection, fuse to ensure the safety of use.
3. Misoperation statistics and control system
After the student swipes the card, the teacher machine to its identity carries on the confirmation, after the confirmation correct gives the student to operate the table the electricity.At the same time, the teacher’s on-board computer can display the online students’ operation situation in real time and monitor it through the video. If the student’s on-board computer misoperates, the teacher’s on-board computer can display the wrong operation of his/her workstation and record the wrong operation.If the teacher needs to save the student’s operation video, he/she can directly press “save” on the video monitoring software to save the video.
3.1 statistics of incorrect operation:
1. The short circuit caused by the wrong operation may be counted and displayed on the digital tube. The power can only be turned on by swiping the card after each power failure.
3.2 control system:
1. equipped with a piece of RFID module, each time on the power should be swiped card, after the break also need to be swiped card to power.
2. Communicate with the host computer of the teacher terminal through the network cable, and the host computer of the teacher terminal can check the number of incorrect operation of each platform and control the power failure of each platform
3. The upper computer has the function of examination mode: one-key up and down power control and countdown.
