Electricity information collection system based on medium voltage power carrier and control method thereof

Abstract

The present invention discloses an electricity information collection system based on a medium voltage power carrier and a control method thereof. The system comprises a concentrated copy main station which is connected with a medium-voltage carrier host, the medium-voltage carrier host is connected with a coupler, the coupler is connected to a medium-voltage carrier slave and is coupled to a 10KV medium-voltage electric power circuit; the medium-voltage carrier slave is connected with a concentrator, and the medium-voltage carrier host/slave is composed of a high-speed carrier chip SSC1664/1663, an interface module connected with the medium-voltage carrier host/slave and configured to connect with the concentrated copy main station and an unvarnished transmission module configured to receive data. According to the invention, when data is transmitted, the highest rate can reach up to 5Mbps, the lowest rate can reach up to 100kbps, and the transmission rate is far superior to the transmission rate of the current medium-voltage power line carrier communication system, and the electricity information collection system based on the medium voltage power carrier and the control method thereof can support the new business development with high transmission rate requirement such as cost control, telecommand, telemetering and remote regulation, and remote switching of a valve.

Description

technical field [0001] The invention belongs to the technical field of power splitters, in particular to a power consumption information collection system based on a medium-voltage power carrier and a control method thereof. Background technique [0002] In the power consumption information collection system, the uplink (concentrator to master station) usually uses GPRS, optical fiber, or power private network for data transmission. GPRS has the advantage of easy installation, and the rate is low (usually around tens of kbits); although the rate of optical fiber and electric power private network is high, it faces the problems of large initial investment and difficult maintenance in the later stage, and in the current power consumption information collection system, The remote communication technology mainly adopts wireless public network such as GPRS / CDMA, optical fiber private network, 230 MHz private network, other communication methods, etc. The overall main problems are...

Problems solved by technology

[0003] 1) Long-term, large-scale applications generate a large amount of rental fees, and data traffic statistics are opaque;

[0004] 2) Business applications depend on the network resources provided by operators, and the application level and promotion progress are subject to the degree of public network construction;

[0005] 3) Public network communication firstly meets the business application of public users, and cannot guarantee service quality requirements such as real-time performance and delay;

[0006] 4) There is a risk of upgrading the public network system;

[0007] 5) The network coverage area is not completely consistent with the power supply area, which may lead to roaming charges;

[0008] 6) There are wireless public network coverage blind spots in the installation position of the electricity consumption information collection terminal
