Abstract

The invention discloses an automatic grading device for gear detection of a pointer multimeter, which belongs to the technical field of electronics and comprises a front shell, a rear shell, a power adapter socket, a test terminal, a matrix keyboard, a voice outlet hole and a TFT color screen. The front shell and the rear shell are arranged in a covering manner and are internally provided with a detection scoring circuit. The detection scoring circuit comprises a gear detection circuit, an examination parameter generation circuit unit, a controller circuit, a matrix keyboard module, a voice broadcast module and a TFT color display screen circuit. Universal gears are detected through the gear detection circuit, grading of the gears is achieved, then resistance or voltage or current is generated through the examination parameter generation circuit unit to be measured by a universal meter, students input measured data, and the structure integrating automatic grading and detection is achieved. Therefore, the checking stage of the universal meter of the electrician is more convenient, more labor-saving and time-saving, and the efficiency is higher.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an automatic scoring device for detecting the position of a pointer multimeter. Background technique [0002] In the existing electrician training or electrician certification, the multimeter assessment among the three meters is time-consuming. The examiner has to check in real time whether the gear of the student's meter is correct, and then give the student a score. This assessment method is very labor-intensive. Teachers or examiners will be very tired after a whole day, so it is necessary to design a device that can replace the manual assessment of the multimeter, so it is necessary to design a device that can detect the gear position of the multimeter and automatically score. Contents of the invention [0003] The purpose of the present invention is to provide an automatic scoring device for detecting the position of a pointer multimeter, which solves the technical pro...
