摘要: 针对大系统中共存的多种通信网络和同种网络多种接口互相通信的需要,采用LPC2368 SOC结合RTL-RTX实时操作系统,研制一个支持多种通信网络及接口互相转换的模块,实现以太网、串口网、CAN网(现场总线网)和USB之间的通信,以及RS232, RS422和RS485接口之间的通信。从线速上对网络转换速度进行定量分析,指出该模块使用时的极限约束条件。

Abstract: For the needs of communication between a variety of communication networks and interfaces in the same network which coexist in large-scale systems, a conversion module which supports communication between a variety of communication networks and interfaces is developed based on LPC2368 and the real time operating system of RTL-RTX. The module supports the communication between Ethernet, serial network, CAN(fieldbus network) and USB, as well as RS232, RS422 and RS485 communication interfaces. The limit conditions to use the conversion module are pointed out based on the quantitative analysis for the conversion rate in the network wire-speed.

Key words: LPC2368 microcontroller, communication network, line-speed
