Abstract

The invention relates to a battery power consumption prompting device, in particular to a prompting device and a prompting method for power consumption of a battery of an instrument. The instrument comprises the battery and an electric quantity displaying device, wherein the battery is connected with a voltage detecting circuit; the voltage detecting circuit is connected with an A/D (analog/digital) converter; the A/D converter is connected with an input end of a singlechip; and an output end of the singlechip is connected to a liquid crystal display device and a loudspeaker. The prompting device can prompt a worker in time when the electric quantity of the instrument is insufficient; the worker can timely charge the instrument conveniently; and moreover, the prompting device displays the rest electric quantity, so that the worker can calculate the rest working time of the instrument conveniently, and the service life of the instrument 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...
