Study of Adaptive Network Transmission Protocol in Mine

Abstract:

Combined with the transmission characteristics of multi node under master-slave mode, the paper design a high speed parallel transmission network based on RS485 bus, realize sampling nodes on the bus communication data packet detection using the ring buffer technique, and use the hardware timer and system parameters in the controller, combine with a custom packet to complete point to point protocol design of broadcast communication, in order to realize the free cutting of the whole system and reliable control and stable data transmission and node. The actual field test that communication rate has no error and error operation under the condition of the cable length of 2 Mbps and 100 m.
