A business data scheduling method for a micropower wireless communication network in a smart grid

Abstract

The invention relates to a business data scheduling method for a micro-power wireless communication network in a smart grid, and belongs to the field of power Internet of things. The method includes: according to the different requirements of different service types in the network, reasonably dividing the service data into static priorities; synchronizing the micro-power wireless communication network in the smart grid, and discretizing the time into a series of time slots t=1, 2 ,…; Periodically detect the data packets transmitted in the network, and discard the data packets that cannot be transmitted to the destination node before the remaining time is exhausted; the data packet scheduling mechanism based on dynamic priority. The invention reasonably classifies the service data and clarifies the requirements of various service data; the node periodically discards the unqualified data packets to avoid the waste of network resources; the service data packet scheduling method based on the dynamic priority satisfies the High-priority business data requires real-time and reliability, while avoiding the starvation problem of low-priority business data.

Description

technical field [0001] The invention belongs to the field of electric power internet of things, and relates to a business data scheduling method of a micropower wireless communication network in a smart grid. Background technique [0002] The micropower wireless communication network is a multi-hop self-organizing wireless sensor network capable of two-way communication applied in the smart grid. In practical applications, the micro-power wireless communication network can not only maintain the versatility and coexistence with the power line carrier communication network, but also can make up for the disadvantages of the power line carrier communication in some scenarios. Putting the developed micro-power wireless communication module into concentrators, energy meters, collectors and other equipment can realize functions such as information collection, equipment control, and emergency reporting of intelligent power distribution equipment. [0003] The micropower wireless co...

Problems solved by technology

[0006] However, in practical applications, the current micro-power wireless communication network has the following problems: lack of classification of business functions, unable to meet the needs of different business functions; two-way interactive network, the transmission of data packets often has a deadline, beyond the deadline Data packets waste network resources; for the queuing problem of business data in nodes, the existing micro-power network simply adopts a first-come-first-served strategy, which cannot meet the timely reporting of emergency events, which brings potential hidden dangers
