本文提出在电气化铁路远动系统中采用高性能、低价格、灵活易用的通讯网络ＢＩＴＢＵＳ构成分层的分布式网络系统，用网络结构代替常规的双机加切换器的结构。既简化了系统结构又成功地解决了系统资源的共享与分配，并为系统以后可能的扩展与联网打下了基础。运用软件工程学的有关技术和方法开发系统软件，使系统结构清晰。易于维护和扩充。本文针对电气化复线渡线开关监控系统的特点，给出了该系统采用的软、硬件方案及其实现过程。
In this paper, the hierarchical distributed network system composed of high performance, low price, flexible and easy to use communication network BITBUS is proposed in the telecontrol system of electrified railway, and the network structure is used to replace the structure of the conventional dual machine switch. It not only simplifies the system structure but also successfully solves the system resource sharing and distribution, and lays the foundation for the possible future expansion and networking of the system. The use of software engineering technology and methods related to the development of system software, the system structure is clear. Easy to maintain and expand. In this paper, according to the characteristics of the monitoring system of electrified double-track crossing switch, the software and hardware solutions and the realization process of the system are given.
