Self-healing ad hoc network communication system of smart power grid

Abstract

The invention discloses an intelligent power grid self-healing ad-hoc network communication system, and the system comprises a plurality of power grid towers; an ad-hoc network communication device isarranged on each power grid tower, a wireless network card module is arranged on the ad-hoc network communication device, and the wireless network card module is connected with the ad-hoc network communication device; the wireless network card module adopts a WiFi network card with a USB interface, the wireless network card module comprises an RT5572 wireless network card, a power amplifier and again antenna, the RT5572 wireless network card is connected with the power amplifier, the power amplifier is connected with the gain antenna, and the gain antenna is connected with the USB interface;and the ad hoc network communication devices on the plurality of power grid towers communicate with one another by adopting a DSR dynamic routing protocol. According to the embodiment of the invention, the method achieves the coverage of the whole-region wireless communication private network, saves the high wiring cost, achieves the self-healing function of an ad hoc network, and maintains the stability of a local area network.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a self-healing self-organizing network communication system for a smart grid. Background technique [0002] The digital transformation and construction of the power grid will inevitably have massive IoT data access requirements, and there is an urgent need to build an economically flexible, two-way real-time, safe, reliable, and all-round coverage "ubiquitous, full-coverage" terminal communication access network. China Southern Power Grid Corporation has also made a strategic deployment for the last mile of WAPI secure network access to substations. However, using traditional AP point selection and business access solutions requires a lot of wiring work, and at the same time, the coverage is not wide, and the network single point is paralyzed. It will lead to a state of paralysis of the entire network. Contents of the invention [0003] The purpose of the present inven...
