Description
Technical field
The utility model relates to intelligent instrument field, is specifically related to the hardware circuit for the sampling of intelligent instrument battery power consumption.
Background technology
In order to adapt to the implementation of China's step price and tou power price policy, Guo Wang company started to promote intelligent electric energy meter from 2010.The key that ammeter time sharing electrical energy and ladder electricity correctly measure is the accuracy of ammeter timing, and time of mistake will cause rate to switch makeing mistakes, and freezes electricity unloading time of origin mistake etc. and affects the problem that ammeter normally measures.The reason affecting clock accuracy is that clock chip breaks down or power-off.And affect the reason that clock chip normally works and mainly contain the following aspects: the aspects such as clock chip crystal oscillator, temperature compensation, Clock battery and cell circuit, and due to current intelligent electric meter occur battery undervoltage fault get more and more, operating number of faults is in rising trend, and failure condition can not be ignored.
Battery undervoltage problem perplexs manufacturing enterprise and State Grid Corp. of this industry always, in the coming years by being one of very outstanding great quality problems, there is no good solution.
Battery power consumption in process of production, detects by Traditional Man in the manufacturing enterprise of intelligent instrument, cannot effective problems such as institute's battery power consumption that causes is excessive in control procedure, does not also have good detection means simultaneously, there is hidden danger of quality blind area before product export.
To the intelligent instrument product in operation of power networks, because product cannot detect the power consumption under cell operating status.Because battery is disposable products, the result analyzed after battery undervoltage fault occurs is that product power consumption is normal, and battery capacity is also normal consumption.There is very large discrepancy with battery capacity theory calculate, act normally because rear various phenomenon occurs fault, this just considerably increases the analysis difficulty of problem, owing to can not find problem place, causes solving problems and also has no way of doing it.
Utility model content
The purpose of this utility model is to provide one can detect battery power consumption automatically, is in operation and can detects the dynamic hardware circuit of battery power consumption constantly.
The utility model is achieved through the following technical solutions: for the hardware circuit of intelligent instrument battery power consumption sampling, comprise Clock battery, MCU single-chip microcomputer, one end of the negative pole connecting valve J1 of described Clock battery, the other end ground connection of described switch J1, the positive pole of described Clock battery connects one end of the 3rd resistance and the first resistance, the other end of described first resistance connects one end of the second resistance and the second electric capacity, one end of described second electric capacity connects MCU-AD, the other end all ground connection of described second electric capacity and the second resistance, the other end of described 3rd resistance connects the positive pole of diode VD1, the negative pole of described MCU single-chip microcomputer and described diode VD1, MCU-VDD power supply, one end of load RL connects, the other end ground connection of described load RL, the two ends of described 3rd resistance are connected with two input ends of differential amplifier, and the output terminal of described differential amplifier connects AD sampling A/D chip, and described differential amplifier and AD sampling A/D chip feed back signal to MCU single-chip microcomputer.
As preferably, the model of described differential amplifier is THS4509.
As preferably, the model stating AD sampling A/D chip is CS5460.
The power consumption index under cell operating status cannot be detected due to current production, therefore, fixed partial pressure resistance simulation signals collecting on battery circuit can be come by differential amplifier by the utility model, by AD sampling A/D chip, simulating signal is converted to digital signal, and set sample frequency, obtain sampled signal, then sampled signal is fed back to the power consumption calculating battery in MCU single-chip microcomputer, this design can detect battery power consumption automatically, manual detection can be replaced by automatically detecting battery, not only can enhance productivity, solve the quality control blind area in production run simultaneously, and also add before dispatching from the factory and again detect battery power consumption, guarantee that in processing procedure, product without exception flows out, the more important thing is and solve product after dispatching from the factory, be in operation and can detect the dynamic of battery power consumption constantly, the abnormity point relatively carrying out analytic product is changed dynamically by power consumption, for problem analysis provides clue and help, and by the analysis to problem, solve, the measures such as prevention effectively solve the problem of battery undervoltage in industry.
Usefulness of the present utility model is: 1) adopt and automatically detect replacement manual detection, efficiency is significantly promoted, and qualifying point is guaranteed, and data have record to be convenient to counter looking into simultaneously; 2) again detect battery power consumption before dispatching from the factory, guarantee that in processing procedure, product without exception flows out; 3) still can monitoring the power consumption under cell operating status after product export constantly, providing foundation for effectively analyzing.
