A network control method for distributed intelligent test system

Abstract

The invention provides a communication framework used for a distributed intelligent test system and a network control method. The communication framework comprises a CPU module, a communication scheduling analysis module, a PPC communication module, a DSP calculation module and an FPGA module, wherein the communication scheduling analysis module and the PPC communication module are respectively connected with the CPU module, and the DSP calculation module is directly connected with the PPC communication module and the FPGA module in a bi-directional interconnection mode. The communication framework is responsible for communication program matching of a sub machine and a main machine of the distributed intelligent test system of a transformer substation and instruction downloading and code calculation of the main machine, exchanges data in real time through an optical fiber network and a tested device for various tests, provides preemptive scheduling modes of IP addresses of multiple devices and multiple systems, and meets strict requirements of a site for real-time and reliable application of data interaction.

Description

technical field [0001] The invention relates to a communication framework and a network control method for a transformer distributed intelligent test system, belonging to the technical field of power system smart grid communication. Background technique [0002] The smart substation system is composed of smart electronic devices that work together to complete various functions of the smart substation system. There is an interdependent relationship between intelligent electronic devices. This dependence is completed through the configuration information or configuration software of each device. It has the flexibility of timely adjustment and the possibility of configuration coordination errors. Therefore, it is necessary to implement the intelligent substation system Run a comprehensive overall test of function and performance. The substation distributed intelligent test system adopts a distributed pattern, equipped with a powerful sub-machine platform and system combination...
