Problems solved by technology

Due to the large number of experimenters, the inspection, testing, and performance evaluation of each experiment result take up about half of the total class time. The real time for guiding students in experiments is insufficient, and at the same time, it causes a lot of workload for teachers and laboratory personnel.
[0009] Patent (CN200520101198.9) "Embedded Intelligent Digital Circuit Experimental Instrument" discloses an experimental instrument for evaluating experimental results, and only proposes "automatic evaluation of experimental process", "microprocessor database", "self-learning", "embedded "Microprocessor", "network" and other concepts, did not explain the specific implementation methods, and only to detect the errors in the students' experiments, rather than the overall evaluation of the students after completing the experiments, which is not conducive to the students' experiments. Overall Evaluation and Students' Learning of the Overallity of Circuits

Abstract

The invention discloses a digital electronic technology experiment system based on intelligent evaluation, comprising a single chip microcomputer minimum system in connection with a liquid crystal display screen, a logic pen, a real time clock, a plurality of buttons, a plurality of controlled logic level wiring sockets, a plurality of controlled single pulse source wiring sockets and a plurality of continuous pulse source wiring sockets, and driving a plurality of nixie tubes; the single chip microcomputer minimum system is in connection with a buzzer, a nixie tube decoding selection switch, a plurality of nixie tube wiring sockets, a plurality of light emitting diode wiring sockets and a plurality of logic level switches through a parallel-in serial-out shifting register. The digital electronic technology experiment system has an ''experiment state'' and an ''evaluation state''. Functions of a conventional digital electronic experiment box can be realized in the ''experiment state''; in the ''evaluation state'', an experiment circuit is intelligently evaluated according to evaluation rules, thereby substantially reducing the amount of work including check, test and score evaluation for teachers and experiment personnel, allowing students to independently complete digital circuit experiments, and benefiting for performing open experiments.
