Electric energy metering data acquisition system

Abstract

The invention discloses an electric energy metering data acquisition system, which comprises an electric energy metering and collecting device, a Lora collector, a Lora repeater and a server, whereinthe Lora collector is connected with one or more electric energy metering and collecting devices so as to be used for receiving feedback data; the Lora repeater is in wireless communication connectionwith one or more Lora collectors to be used as a relay node; and the Lora repeater is connected with a server by means of the Ethernet to be used for transmitting electric energy metering data. According to the electric energy metering data acquisition system, networking is realized by means of the Lora module, the working frequency band of the Lora module is a free frequency band, only the communication cost of the Lora repeater and the server needs to be paid, and the cost is saved; moreover, the networking range of the Lora repeater and the Lora collector can reach 2-5km and is enough to cover all regions of a single district, stable data communication is maintained, combined networking of a plurality of districts can be realized, the cost is further saved, and the maintenance workloadis reduced.

Description

technical field [0001] The invention relates to the field of electric energy data acquisition, in particular to an electric energy metering data acquisition system. Background technique [0002] With the increase of power grid construction and coverage area, the demand for smart grid construction is also gradually increasing, and the requirements for the collection efficiency and data accuracy of electric energy metering data are getting higher and higher. Now, the electric energy metering data collection of residential quarters mainly adopts remote In the way of meter reading, the data of residents’ electric meters is collected through the collector, and the collector communicates with the main station server through the GPRS module to transmit the energy measurement data. However, this method needs to install a large number of collectors with GPRS modules in residential areas where the meters are scattered. Each collection terminal needs to be equipped with the SIM card of...

[0002] With the increase of power grid construction and coverage area, the demand for smart grid construction is also gradually increasing, and the requirements for the collection efficiency and data accuracy of electric energy metering data are getting higher and higher. Now, the electric energy metering data collection of residential quarters mainly adopts remote In the way of meter reading, the data of residents’ electric meters is collected through the collector, and the collector communicates with the main station server through the GPRS module to transmit the energy measurement data. However, this method needs to install a large number of collectors with GPRS modules in residential areas where the meters are scattered. Each collection terminal needs to be equipped with the SIM card of the operator, the cost of communication fees is high, and the GPRS module is easy to drop the line, and the later maintenance is cumbersome; some manufacturers install 433MHz micro-power wireless modules on the collectors, and install them in the center of an area The GPRS terminal with the 433MHz micro-power wireless module is networked with the collectors in this area, and transmitted to the main station server through GPRS, but the transmission distance of the 433MHz micro-power wireless module is only 2,300 meters, which cannot cover a large area and the group The network is unstable, and the communication quality of the collector far from the center is poor
