对电机车架线载波通信系统采用以STEL-2000A直接序列扩频芯片为核心的硬件系统设计方案,着重介绍系统的硬件实现和主控制模块的软件流程。实验表明了扩频技术在该载波通信系统中的可行性。
The design of hardware system based on STEL-2000A direct sequence spread spectrum chip is adopted for the motor frame line carrier communication system. The hardware implementation of the system and the software flow of the main control module are mainly introduced. Experiments show that the spread spectrum technology in the carrier communication system feasibility.
