Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0030] Such as figure 1 As shown in , it is a schematic diagram of a distributed wireless communication system for power distribution and consumption. Within the coverage of the wireless private network, several power distribution and consumption devices are scattered. During the operation of these power distribution equipment, various power information data will be continuously generated, including "three remotes", centralized reading, remote meter reading, video monitoring, voice dispatching, etc. The system includes a base station configured with distributed multi-antennas, and multiple power distribution and consumption devices configured with single antennas. The base station is composed o...

Abstract

The invention discloses a user scheduling method for power distribution communication. When the scheduling cycle is reached, the waiting time of each service of each user and the statistical channel status of each user's access channel in several recent scheduling cycles are determined first. Information, according to the waiting time of each user and the statistical channel state information, use the criterion of maximum throughput under the maximum waiting delay constraint to perform user scheduling, and pair the remote radio frequency unit with the user; the statistical channel state information includes Channel reception correlation matrix and signal-to-noise ratio. According to whether the waiting time exceeds the maximum delay constraint, the present invention puts each user service into the first-level service pool and the second-level service pool. Selecting user services and scheduling users based on the criterion of maximizing throughput can make full use of the wireless communication system bandwidth while satisfying user service delay constraints.

Description

technical field [0001] The invention relates to a user scheduling method oriented to power distribution communication, which belongs to the technical field of electric power information communication. Background technique [0002] The power communication system is the foundation of smart grid construction. The construction of smart grid covers multiple links such as smart power generation, smart power transmission, smart power transformation, smart power distribution, smart power consumption and smart dispatching, and communication and information technology is the core support platform for smart grid construction. In the power distribution and consumption links in the smart grid, there are distribution network switch stations, power distribution rooms, ring main unit, pole-mounted switches, distribution transformers, distributed energy sites, electric vehicle charging stations, distribution lines, and centralized user communities. Devices and other medium and low voltage p...
