Power supply electricity prompting device for instruments and meters

Abstract

The present invention relates to a battery electricity prompting device and specifically relates to a battery electricity prompting device for instruments and a prompting method thereof. The device includes a battery and an electricity quantity display device. The battery is connected with a voltage detection circuit. The voltage detection circuit is connected with an A / D converter. The A / D converter is connected with the input end of a single-chip microcomputer; The output end of the single-chip microcomputer is connected with a liquid crystal display device and a loudspeaker. According to the invention, when an instrument / meter is short of power, the power shortage condition can be timely reminded. Therefore, the working personnel can timely charge the instrument / meter, and the residualelectricity quantity is displayed at the same time. As a result, the working personnel can conveniently calculate the residual working time of the instrument / meter, so that the service life of the instrument / meter is prolonged.

Description

technical field [0001] The invention relates to a battery power consumption prompting device, in particular to a prompting device and a prompting method for an instrument battery power consumption. Background technique [0002] With the development of society and technology, people's living standards and quality of life are increasing day by day, and the safety requirements for power equipment are becoming more and more stringent. Therefore, the safety testing of new equipment and equipment that has been put into operation is becoming more and more important. Many devices now use instrumentation to measure its safety and reliability. However, some instruments need to be charged before use. However, since the instrument does not have the function of displaying the remaining battery power, in order to prevent the work from being interrupted due to a sudden power failure during work, only regular charging can be used. The charging time depends entirely on the staff. Judgment b...

AI Technical Summary

Problems solved by technology

However, some instruments need to be charged before use. However, since the instrument does not have the function of displaying the remaining battery power, in order to prevent the work from being interrupted due to a sudden power failure during work, only regular charging can be used. The charging time depends entirely on the staff. experience judgment

On the one hand, this approach still cannot completely avoid the sudden power failure during work, and at the same time, high-frequency charging has a certain impact on the service life of the instrument itself.
