Abstract

The invention discloses a wireless resource allocation method for an uplink channel of an intelligent substation based on a 5G network. The wireless resource allocation method comprises the following steps: 1, constructing an uplink network environment of the intelligent substation; 2, calculating a signal-to-noise ratio and a bit rate of nodes in the transformer substation by adopting an adaptive modulation coding method; 3, establishing a maximum bit rate optimization model with a stepwise function by taking the maximum bit rate of node transmission as a target function and taking limiting factors of 5G communication as constraint conditions; 4, reconstructing the spectral efficiency by adopting a spectral efficiency approximation function, establishing an optimal bit rate linear programming model, and distributing an optimal modulation coding scheme and resource blocks for each node in the transformer substation. According to the invention, cooperative resource allocation of the sensor and the inspection robot in the transformer substation can be supported, and the transmission rate of the system is maximized under the condition that the delay requirement is met.
