Problems solved by technology
The function of the traditional electric meter is relatively simple, often only has the function of measurement and display, that is, it can realize the stable and accurate measurement of the user's electricity consumption and display
[0003] However, in the actual use process, these traditional mechanical meters have low accuracy and narrow measurement range, and cannot provide accurate metering statistics, which affects the user's electricity consumption and electricity bill settlement, and is also vulnerable to external magnetic fields. interference, there are defects such as short life and high failure rate

Embodiment Construction
[0034] figure 1 The detailed modules of the DC electric energy meter in an embodiment are shown, and the direct current electric energy meter includes: a detection module 100, a verification module 200, a communication module 300, a processing module 400, a storage module 500, an interaction module 600 and a clock module 700, and the processing Module 400 is the core of the DC energy meter, where:
[0035] The detection module 100 is used to sample voltage and current, obtain voltage signals and current signals, and convert them into detection signals and transmit them to the processing module 400 . The detection signal is a small-amplitude signal, that is, the obtained strong current voltage signal and current signal are converted into weak current voltage signals and current signals, that is, weak current signals that can make electronic devices work normally. In one embodiment, the detection module 100 collects high-voltage DC voltage and current to obtain high-voltage DC ...

The invention discloses a direct-current electric energy meter and a method for metering direct-current electric energy. The meter at least comprises a detection module, a processing module, a storage module and an interaction module, wherein the detection module is used for sampling voltage and current, acquiring a voltage signal and a current signal, converting the voltage signal and the current signal into a detection signal and transmitting the detection signal to the processing module; the processing module is used for calculating an electric energy parameter according to the detection signal and storing the electric energy parameter in the storage module; the storage module is used for storing the calculated electric energy parameter; and the interaction module is connected with the processing module and is used for acquiring and displaying the calculated electric energy parameter. Compared with a conventional direct-current electric energy meter which has a mechanical electromagnetic structure, the brand new direct-current electric energy meter adopting full-electronic apparatuses has high metering degree of accuracy, longer service life and anti-external disturbance capacity.
Description
【Technical field】 [0001] The invention relates to a metering device and method, in particular to a DC electric energy meter and a DC electric energy metering method. 【Background technique】 [0002] The traditional electric meter uses a mechanical metering device. The mechanical counter records the user's electricity consumption. Most of them are installed outdoors. They are relatively stable during use and the recorded data is not easy to lose. The traditional electricity meter has a single function, and often only has the functions of measurement and display, that is, it realizes the stable and accurate measurement and display of the user's electricity consumption. [0003] However, in the actual use process, these traditional mechanical meters have low accuracy and narrow measurement range, and cannot provide accurate metering statistics, which affects the user's electricity consumption and electricity bill settlement, and is also vulnerable to external magnetic fields. i...
