Electrical energy data acquiring system based on wireless mesh ad hoc network

Abstract

The invention relates to an electrical energy data acquiring system based on a wireless mesh ad hoc network, which comprises a main station system, a concentrator and a collector; wherein the main station system comprises a database server, a communication server and a WEB server; a three-in-one distribution transformer monitor is adopted by the concentrator, and comprises a metering monitoring module, a wireless ad hoc network module, a GPRS / CDMA communication module, a first memory and a first microprocessor; the collector comprises an I-type wireless electric energy meter which includes a metering module, the wireless ad hoc network module, a second memory and a second microprocessor; the three-in-one distribution transformer monitor is connected with the wireless mesh ad hoc network formed by the I-type wireless electric energy meter; and the three-in-one distribution transformer monitor is also connected with the main station system. By adopting the wireless mesh ad hoc network communication technology, the system can realize the embedded development technique with the three-in-one function of a gateway meter, the concentrator and the distribution transformer monitor, thus reducing the costs of manufacturing, constructing and running as well as improving the real-time property of communication.

Description

(1) Technical field [0001] The invention relates to a remote information collection system of a power distribution network, in particular to a power data collection system based on a wireless mesh ad hoc network. (2) Background technology [0002] At present, the collection of electric energy data mainly adopts power line carrier, 485 communication + infrared handheld or GPRS / CDMA and ZIGBEE wireless communication. The disadvantage of power line carrier is that the real-time performance of data transmission is poor. In extreme cases, it takes 24 hours to transmit the data back. 485 communication + infrared handheld or GPRS / CDMA system has two defects: the first is to increase the amount of construction, and the second is that infrared handheld requires personnel to go to the site; GPRS / CDMA requires communication fees. The disadvantage of ZIGBEE wireless communication is that the application it is designed for is not used for the collection of electric energy data, so its s...

Problems solved by technology

The disadvantage of power line carrier is that the real-time performance of data transmission is poor. In extreme cases, it takes 24 hours to transmit the data back.

485 communication + infrared handheld or GPRS / CDMA system has two defects: the first is to increase the amount of construction, and the second is that infrared handheld requires personnel to go to the site; GPRS / CDMA requires communication fees

The defect of ZIGBEE wireless communication is that the application it is designed for is not used for the collection of electric energy data, so its standard power is low, the transmission distance is not enough, and additional power amplification components need to be added
