Abstract
The invention discloses a method for monitoring the power consumption of an energy meter battery. A battery power consumption monitoring function is added on the basis of the original solution. The voltage sampling is performed on a fixed voltage divider resistance on a battery circuit; a voltage value obtained by sampling is transformed into a current value through software processing calculation, and the current value is stored, so that whether the problems are caused by the battery or the product can be distinguished easily by recording, analyzing and comparing the values. At the same time, the monitored values can be copied by a master station and is transmitted to the master station, so that staffs can check the working status of the electric meter in time and take preventive measures.
Description
Technical field
The present invention relates to intelligent instrument field, be specifically related to the method for electric energy meter battery consumption detection.
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.
Intelligent electric meter is in client test side or market operational process, occur that battery undervoltage fault gets more and more, can affect the accuracy between table timing after battery undervoltage, time of mistake will cause rate to switch makeing mistakes, and freezes that electricity unloading makes a mistake, centralized meter-reading system is copied and do not returned data etc.Because battery is disposable products, tired degree is greatly caused to fault analysis, and product only has the function of copy reading battery operating voltage, this function to be helpless to analyze the real reason of battery undervoltage at present.Owing to lacking monitoring battery capacity or the measuring ability of battery power consumption, causing problem cannot analysis and solutions, bringing very large trouble by giving power supply administration and client.
