Abstract
The utility model discloses an instrument current recorder, which comprises a microcontroller, a Hall sensor, a RTC clock, a FLASH memorizer and a power supply. The Hall sensor is connected with an AD interface of the microcontroller. The FLASH memorizer and the RTC clock are respectively connected with a SPI interface of the microcontroller. The power supply provides electricity for the microcontroller, the Hall sensor, the RTC clock, the FLASH memorizer and a USB interface. The Hall sensor is connected in series in the power supply of the instrument. When the instrument is electrified, the Hall sensor converts current to corresponding voltage value and send it to the AD interface of the microcontroller. After AD sampling, analog quantity is converted to digital quantity. Through the RTC clock to record time, time value and current value corresponding to hour are stored in the FLASH memorizer by the microcontroller. According to the utility model, service condition of the instrument can be accurately recorded, and time-consuming, laborious and inaccurate conditions by traditional manual statistics are replaced.

The utility model content
The purpose of this utility model is to provide a kind of instrument galvo-recorder, the accurately operating position of register instrument.
the technical scheme that realizes the utility model purpose is: a kind of instrument galvo-recorder, comprise microcontroller, Hall element, the RTC clock, FLASH storer and power supply, Hall element is connected with the AD interface of microcontroller, the FLASH storer is connected with the RTC clock with the SPI interface of microcontroller and is connected, power supply is to microcontroller, Hall element, the RTC clock, the FLASH storer, the USB interface power supply, Hall element is serially connected in the power supply of instrument, after the instrument energising, Hall element is sent into current conversion the AD interface of microcontroller for corresponding magnitude of voltage, after the AD sampling, analog quantity is converted into digital quantity, pass through the RTC clock log time by microcontroller, time value and the current value in the corresponding moment are stored in the Flash storer.
The utility model compared with prior art, its remarkable advantage is: (1) possesses accurate clock, jumbo storage system based on the Instrument use situation register of microcontroller.(2) data export interface easily.Can easily gather, store and derived data.(3) can accurate recording the operating position of instrument, replaced traditional complicate statistics, time-consuming, effort and inaccurate situation.(4) leave simultaneously clock check and correction interface, guarantee the accuracy of clock.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Description of drawings
Fig. 1 is the theory diagram of instrument galvo-recorder.
Embodiment
in conjunction with Fig. 1, the utility model instrument galvo-recorder, comprise microcontroller, Hall element, the RTC clock, FLASH storer and power supply, Hall element is connected with the AD interface of microcontroller, the FLASH storer is connected with the RTC clock with the SPI interface of microcontroller and is connected, power supply is to microcontroller, Hall element, the RTC clock, the FLASH storer, the USB interface power supply, Hall element is serially connected in the power supply of instrument, after the instrument energising, Hall element is sent into current conversion the AD interface of microcontroller for corresponding magnitude of voltage, after the AD sampling, analog quantity is converted into digital quantity, pass through the RTC clock log time by microcontroller, time value and the current value in the corresponding moment are stored in the Flash storer.The RTC clock can per minute record one secondary data as triggering.
The utility model instrument galvo-recorder also comprises a USB interface, and USB interface is connected the USB mouth and is connected with microcontroller, and time value and corresponding constantly current value are derived data by the USB mouth.
Microcontroller by the clock log time relationship of RTC is:
, wherein T is that sampling period, i (t) represent the discrete electrical flow valuve, I is current effective value.The operating position of register instrument:
D is for adding up to the corresponding per minute current value of number of days i
The utility model judges based on the current value of measuring instrument whether instrument works.By Hall element, current value is converted into magnitude of voltage.By microcontroller AD sampling, obtain the current current value of instrument after conversion.Instrument use situation register per minute record one secondary data.But in order to guarantee sampling precision, as every in microcontroller 10 seconds once sampling.Sampling is 6 times in one minute.After 6 secondary data weightings are processed, obtain the current value of this minute, then be stored to the flash chip.
With respectively 5 of oscillograph, power meter, signal sources.Instrument galvo-recorder record three months after after three months, data being derived, forms form, can facilitate, find out intuitively total on time of instrument, the parameters such as on time section, service efficiency.
