Meter using recorder

Abstract

The invention relates to a meter using recorder. The SPI port of a micro processor C8051F340 is connected to a RTC clock chip and a flash storage chip; a Hall sensor converts a current signal into a voltage signal, AD sampling is performed on the voltage signal through the micro processor C8051F340 to acquire a digital current signal, and the digital current signal is stored into the flash storage chip; meanwhile, the RTC clock serves as triggering to set the time intervals of recording; the current value and the current time are stored in the flash storage chip through the RTC clock chip and the flash storage chip. The meter using recorder has the precision clock and high-capacity storage system, acquisition and storage can be performed conveniently, the using situation of meters can be recorded accurately, the traditional manual counting is replaced with the recorder, and the situations of time and labor force wasting and inaccuracy are avoided; meanwhile, the clock proofreading interface is provided, and the precision of the clock is guaranteed.

Description

technical field [0001] The invention relates to a recorder, in particular to an instrument usage recorder. Background technique [0002] The use of expensive instruments such as signal sources and spectrum analyzers is often recorded manually, which is not only inefficient but also inaccurate. The use of the instrument cannot be counted truly, and the rational configuration of the instrument cannot be achieved, which restricts the actual utilization of the instrument. Inventing a recorder that can truly record the use of instruments and meters in a year can save labor costs and truly record the utilization rate of instruments. Contents of the invention [0003] To solve the above problems, the present invention provides a meter use recorder capable of accurately recording the use of the meter. [0004] In order to solve the above problems the present invention provides a kind of instrument recorder, comprising microprocessor C8051F340, RTC clock chip, Hall sensor, flash ...
