Multi-node synchronous sampling and data transmission method in ring communication network

The invention discloses a multi-node synchronous sampling and data transmission method in a ring communication network. The main node generates a synchronous pulse AD _ CVT and a transmission triggerpulse TX _ SYN which are consistent with a system sampling interval Ts, and meanwhile, the main node completes local real-time data collection under the control of the AD _ CVT and completes data transmission under the trigger of a TX _ SYN signal; meanwhile, each control node divides a physical channel into a real-time logic channel and a non-real-time logic channel, real-time sampling data services are classified into the real-time logic channels to be transmitted, real-time sampling data are extracted in a staggered mode and sent out from two different directions of the ring network, and non-real-time data are classified into the non-real-time logic channels to be transmitted. According to the method, synchronous sampling and synchronous data transmission of each control node in the ring network are realized, and the data sampling efficiency and the data transmission instantaneity are improved.
