Description

A data acquisition device based on electric energy meter

technical field

The utility model belongs to the field of data transmission, in particular to a data acquisition device based on an electric energy meter.

Background technique

With the development of the power system, the existing reading of electric energy meter data has gradually changed from the original manual reading to remote reading. The existing remote meter reading methods mainly include the following three types:

The first method is to use the concentrator to read the data of the electric energy meter, and then save it in the concentrator. The concentrator then regularly transmits the data of these meters to the master station software (or the master station regularly reads the data saved by the concentrator). The concentrator and the electric energy meter together form a remote meter reading control management system, which can store the historical data of meter daily freezing and monthly freezing, and provide data basis for energy consumption analysis. The concentrator has two channels, uplink and downlink. The uplink channel generally uses GPRS wireless mode to realize remote communication with the management center, and the downlink channel generally uses PLC (power carrier) to collect data from the energy meter.

The second method is used in combination with the first method. The electric energy meter is only equipped with a PLC module, and the data is collected for each electric energy meter separately, and then the PLC is transmitted to the concentrator, and the concentrator uploads the data to the master station through the GPRS module.

The third method is to directly use the GPRS module to collect data for each electric energy meter, and then realize remote communication with the management center through GPRS wireless mode to realize the remote meter reading function.

Because the three types of methods have their own advantages and scope of application, the three methods currently exist in remote meter reading at the same time. However, because different customers have different requirements for data collection of electric energy meters, and the existing remote data collection devices are too simple to adapt to the data collection of various electric energy meters, the universality is poor.
