Pointer multimeter online examination system

Abstract

The invention discloses a pointer multimeter online examination system, which belongs to the field of electrician practical training, and comprises a teacher end and a plurality of examination ends. The plurality of examination ends are wirelessly connected with the teacher end, each examination end comprises a multimeter, a meter pen, a multimeter detection protection device, a mobile phone and a test terminal, the meter pen is connected with the multimeter through the multimeter detection protection device, the test head of the meter pen is connected with the test terminal, and the test terminal is wirelessly connected with the teacher terminal through the mobile phone. The test terminal is arranged to replace an electrician box of an electrician, the teacher end inputs examination parameters, wirelessly transmits the examination parameters to the test terminal, and then displays the examination parameters to students to use a multimeter for testing, and then the multimeter detects whether a protection device monitors whether gears hit by the students are correct or not, so that remote automatic score deduction is realized; meanwhile, after measurement by the students, a measurement result is input into the test terminal and then is transmitted back to the teacher end, so that assessment and scoring recording of a remote multimeter are realized, and the problem of electrician practical training assessment in an online class of epidemic situations is solved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an online assessment system for pointer multimeters. 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. The teacher or examiner will be very tired after a whole day, so it is necessary to design a device that can replace the manual assessment multimeter. [0003] Especially in the case of the epidemic, many courses have chosen to take online classes, but for practical electrician training and other online theories, practical training is required to be assessed. Therefore, it is necessary to design an online Electrical testing device. Contents of the invention [0004] The purpose of the pr...
