technical field [0001] The invention relates to a monitoring system in the technical field of communication, in particular to a monitoring system based on an EtherCAT network. Background technique [0002] In the monitoring system, the main task is to perform some necessary control operations on the actuator according to the remote real-time scene and status information feedback. Because there is a certain spatial distance between the control unit and the actuator, it makes Control instructions, feedback information, etc. need to be transmitted through communication methods suitable for long-distance situations.

AI Technical Summary

Problems solved by technology

[0003] The traditional monitoring system has communication technologies such as Ethernet transmission and field bus control. Among them, Ethernet has certain advantages in bandwidth and speed but lacks real-time performance. Therefore, field bus is used to realize mechanism control. To meet the real-time requirements, but the field bus has certain limitations on the transmission rate

On the other hand, the number of sold components of the field bus is very small, and the special type of the field bus is strong, and the protocol conversion between different buses is complicated, so the comprehensive cost of the control system and field devices is quite high

Furthermore, in this traditional solution, there are many wiring harnesses, and the wiring cost is particularly significant.

At the same time, flexibility in terms of signal granularity has traditionally been achieved through modular field devices operating in subordinate subnetworks, which add to the overall complexity of the system and have significant disadvantages in terms of real-time and cycle times
