Based on the cdt protocol and the architecture of hardware , the software which makes use of simple , effectual algorism and assemble language implements the communication of rtu , it completes the data ' s operation , recordation , organization and supervision and it also fulfils the request of real - time and veracity of the system 根据cdt规约,结合硬件结构,本软件采用简单有效的算法,用汇编语言实现了rtu的通信,完成了数据的运算、记录、组织和监控,满足了系统实时性和准确性的要求。
In this paper , we completely discussed and designed the web - based rtu in telecontrol system for electrical railway system . first , in this paper , we divided rtu into internet - rtu , intranet - rtu and normal - rtu on scale . lan method to realize web - based internet - rtu and intranet - rtu and internet - rtu join the internet by adopting the router equipments are given , then , the conjunction mode between lan and el channel and two resolved scheme are designed and compared : router mode and conversion equipment mode 首先,本文把不同规模的被控端分为internet级被控端、 intranet级被控端以及常规被控端,对于internet级被控端和intranet级被控端,本论文采用构建lan的方式实现其web模式的转变,在internet级被控端采取路由器设备连接internet ,接着,本论文对综自被控端lan和e1接口信道的连接方式进行设计与比较,提出使用路由器和接口转换器两种模式。
