Method, system, device and medium for reducing transmission loss in distributed communication system

Abstract

The present application relates to a method, system, device and medium for reducing transmission loss of a distributed communication system, and relates to the technical field of distributed communication systems. The method includes obtaining the types of multiple expansion modules in the distributed communication system and the corresponding module configuration information, wherein the expansion modules are connected to a local programmable high-speed backplane communication chip through a high-speed differential communication interface; establishing a communication connection through a parallel communication interface between the local programmable high-speed backplane communication chip and a main control chip; obtaining a clock signal of the main control chip, and based on the clock signal, controlling the local programmable high-speed backplane communication chip to read and write data; transmitting data to multiple expansion modules in sequence according to the configuration information of the expansion modules, and updating the expansion module status information in the internal storage unit after each transmission is completed, so as to reduce the delay in data transmission. The present application has the effect of improving the transmission efficiency of the distributed communication system.
