Problems solved by technology

[0002] The ammeter, voltmeter, power meter, etc. used for measurement in the laboratory are the most commonly used measurement devices. When students complete an experiment, they often switch between multiple instruments for measurement. Not only do they need to switch multiple wiring lines, but it is not only easy Wrong wiring also greatly prolongs the experiment time, making it extremely inconvenient for students to carry out experiments

Abstract

The invention discloses a laboratory intelligent measuring device based on a single-chip microcomputer. The laboratory intelligent measuring device comprises the single-chip microcomputer, a voltage analog quantity input module, a current analog quantity input module, a key module, a power switch module, an overcurrent protection module and a data memory module. The laboratory intelligent measuring device based on the single-chip microcomputer is provided with a liquid crystal display module, the voltage analog quantity input module is arranged below the liquid crystal display module, the current analog quantity input module is arranged below the voltage analog quantity input module, and the key module is arranged below the current analog quantity input module. And a power switch module and an overcurrent protection module are arranged below the key module. The device is low in price, and can measure two paths of power, two paths of voltage and two paths of current at the same time; the power factor and frequency can be measured, the measurement is convenient, the measurement is safe, the measurement precision is high, the service life is long, and students can trustingly and autonomously carry out experiment measurement.

Description

technical field [0001] The invention relates to a laboratory intelligent measuring device based on a single chip microcomputer. Background technique [0002] The ammeter, voltmeter, power meter, etc. used for measurement in the laboratory are the most commonly used measurement devices. When students complete an experiment, they often switch between multiple instruments for measurement. Not only do they need to switch multiple wiring lines, but it is not only easy Wrong wiring also greatly prolongs the experiment time, making it extremely inconvenient for students to carry out experiments. Therefore, there is an urgent need for an intelligent measuring device that can measure multiple experimental data at the same time, can shorten the experimental time, and realize the measurement of various experimental physical quantities conveniently, quickly and accurately. Contents of the invention [0003] Aiming at the existing deficiencies, the present invention provides a laborat...
