The invention discloses a
power transmission and transformation equipment
Internet of Things node equipment
wireless communication method. A broadcast channel, a downlink
control channel, a multicastchannel, a downlink shared channel, an uplink random competition channel and an uplink shared channel are arranged in a
communication channel between master equipment and slave equipment in the powertransmission and transformation equipment
Internet of Things; different channels are distinguished through channel type fields of the MAC frame header; communication processes between the master device and the slave devices are set and include a node
broadcasting process, a
random access process, a pre-allocation registration process, a scheduling communication process of an uplink shared controlchannel, a
discontinuous reception DRX scheduling communication process, a communication process of a downlink shared
control channel, a packet fragmentation process and the like. According to the invention, standardized access of mA-level
power consumption state sensing sensors with large data volume such as
power transmission and transformation equipment
Internet of Things waveforms and the likecan be satisfied, networking between the aggregation node and the access node is realized, and the requirements of mA-level communication
power consumption, sensor synchronous sampling and reliable networking coverage of a service scene are satisfied.
