Configurable high-accuracy control system of time interval frame release Ethernet interface

The invention discloses a configurable high-accuracy control system of time interval frame release Ethernet interface. The system comprises a frame data control interface module, a self-adaption muS level high-accuracy hardware sequential control module and a high-speed Ethernet communication interface module. The frame data control interface module can develop a data buffer in a self-adaption mode and store corresponding data information according to different data types of the frame data of a sample value or other normal frame data. The self-adaption muS level high-accuracy hardware sequential control module can generate a frame release sequential control mechanism in a self-adaption mode according to a message type, a message content and a high-accuracy sequential requirement which are configured by the system, and select a released contents of the frame data to send to an IP (Internet Protocol)-core-based MAC (Media Access Control) controller of the Ethernet according to the method of high-accuracy timer interruption. The method includes hardware timer interruption triggering, multi-tasking, hardware delay and message frame release. The high-speed Ethernet communication interface module releases Ethernet message frames according to the contents of the group packet of the MAC controller of the Ethernet in high speed. The system can solve the problem of larger jitter delay of the sending interval time of the sampling frame of an intelligent substation.
