Multiple access method for improving data transmission reliability and stability

Abstract: A multiple access method for improving data transmission reliability and stability comprises the following steps: 1) after initialization, a master communication node sends a broadcast network access message to a bus, and slave communication nodes on the bus make responses to access a network and enter a ready state; 2) the master communication node divides all the slave communication nodes that have accessed the network on the bus into N priorities, and carries out polling access to all the slave communication nodes on the bus according to the priorities; 3) when polled by the master communication node, each slave communication node chooses to send monitoring data or a network exiting application to the master communication node according to conditions; 4) after receiving response signals and processing the received signals, the master communication node sends the broadcast network access message for a second time, and the new or pending slave communication nodes that need to access the network can carry out new network access operation when the network access broadcast is monitored; and 5) after completion of the polling on all the slave communication nodes in the network, the master communication node determines priorities of the slave communication nodes for a next polling according to data volumes sent by all the slave communication nodes during the current polling. The method provided by the invention has the advantage that the data communication reliability and stability are improved.
