Abstract
The utility model relates to a kind of Instrument use registering instrument, the SPI mouth of its microprocessor C8051F340 is connected with RTC clock chip and flash storage chip, by Hall element, current signal is converted into voltage signal, voltage signal obtains digital current signal through the AD of microprocessor C8051F340 sampling again, is then stored to flash storage chip; Use RTC clock as triggering simultaneously, the time interval of each record is set; By RTC clock chip and flash storage chip, current value and current time are together stored in flash storage chip; This Instrument use registering instrument, possesses accurate clock, and jumbo storage system can easily gather, store, can the service condition of accurate recording instrument, instead of traditional complicate statistics, time-consuming, effort and inaccurate situation; Leave clock check and correction interface simultaneously, guarantee the accuracy of clock.
Description
Technical field
The utility model relates to a kind of registering instrument, particularly relates to a kind of Instrument use registering instrument.
Background technology
The more valuable Instrument use situation such as signal source, frequency spectrograph is often through manual record, and not only inefficiency, accuracy is not high yet.The service condition of instrument can not be counted really, and do not reach the reasonable disposition to instrument, constrain the practical efficiency of instrument.Invent a kind of can the registering instrument of the service condition of recording instrument in 1 year really, can save labour turnover, the utilization rate of real recorder.
Utility model content
For above problem the utility model provide a kind of can the Instrument use registering instrument of accurate register instrument service condition.
Providing a kind of Instrument use registering instrument to overcome the above problems the utility model, comprising microprocessor C8051F340, RTC clock chip, Hall element, flash storage chip; The SPI mouth of microprocessor C8051F340 is connected with RTC clock chip and flash storage chip, based on the current value of measuring instrument, the present invention judges whether instrument works, by Hall element, current signal is converted into voltage signal, voltage signal obtains digital current signal through the AD of microprocessor C8051F340 sampling again, namely obtain the current value that instrument is current, be then stored to flash storage chip; Use RTC clock as triggering simultaneously, the time interval of each record is set; By RTC clock chip and flash storage chip, current value and current time are together stored in flash storage chip; In order to not only reliable but also fast by statistical conversion, microprocessor C8051F340 carries out communication by USB interface and outside, make native system can carry out exchanges data with other system fast.
This, based on the Instrument use registering instrument of microprocessor C8051F340, possesses accurate clock, jumbo storage system, easily statistical conversion interface, can easily gather, stores and derived data; Can the service condition of accurate recording instrument, instead of traditional complicate statistics, time-consuming, effort and inaccurate situation; Leave clock check and correction interface simultaneously, guarantee the accuracy of clock.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model provides a kind of Instrument use registering instrument, comprises microprocessor C8051F340, RTC clock chip, Hall element, flash storage chip, the SPI mouth of microprocessor C8051F340 is connected with RTC clock chip and flash storage chip, based on the current value of measuring instrument, the present invention judges whether instrument works, by Hall element, current signal is converted into voltage signal, voltage signal obtains digital current signal through the AD of microprocessor C8051F340 sampling again, namely the current value that instrument is current is obtained, use RTC clock as triggering simultaneously, record one secondary data per minute, but in order to ensure sampling precision, sampling should be carried out in every 10 seconds for microcontroller, sampled 6 times in one minute, after 6 secondary data weighting process, obtain the current value of this minute, then flash storage chip is stored to, current value and current time together store by flash storage chip, in order to not only reliable but also fast by statistical conversion, microprocessor C8051F340 carries out communication by USB interface and outside, make native system can carry out exchanges data with other system fast.
The foregoing is only preferred embodiment of the present utility model, be not restricted to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within right of the present utility model.
