Problems solved by technology
However, due to the large volume of the isolated power supply 110 and the need to provide the isolated DC / DC circuit 150 and the optocoupler component 140 for the RS485 circuit 130, the detection device 100 is bulky
If multiple measuring devices 100 are used to monitor multiple power supply sub-circuits respectively, it will take up a lot of space, so this proposed solution is difficult to be applied in practice

The invention relates to a device for acquiring electricity utilization information. The device comprises a data collecting and processing circuit, a non-isolated type power source, a data communication module and an isolating component. The data collecting and processing circuit is used for detecting working parameters about a power supply loop capable of being coupled. The non-isolated type power source is used for converting an alternating current into a direct current to provide an appropriate working voltage for the data collecting and processing circuit. The data communication module is used for modulating the detected working parameters into the preset frequency, wherein the modulated working parameters can be sent with the preset data transmission rate which is higher than the preset data transmission rate so that the sent working parameters can be demodulated. The isolating component is used for providing electric isolation and signal transmission isolation to carry out coupling and isolating on the modulated working parameters. The device not only can achieve electricity utilization subentry metering, but also has the advantage of being small in size.
