基于3G通信的PLC嵌入式监控终端设计与实现 Design and Realization of Embedded Termination of PLC Equipments’ Remote Monitoring Based on 3G Technology

本文以欧姆龙CP1H型号的PLC为应用背景，设计了基于嵌入式linux下3G无线通信的PLC设备远程监控终端。论文针对GPRS与以太网的不足在实际应用的缺陷，提出了基于3G通信技术的数据传输方案，采用S3C6410/ARM11作为控制器和中兴MF210无线模块，采用WCDMA制式，通过在嵌入式linux系统中配置相关驱动，移植PPP套件，编写配置脚本来实现3G通信数据监控功能。介绍硬件设计，驱动移植，网络通信功能的实现过程。本方案具有快速稳定可靠等优点。 Against application background of the CP1H PLC of Omron Company, the design of remote moni-toring system about PLC devices base on 3G network on the embedded Linux platform is realized. The paper puts forward the 3G communication solution according to the shortcomings of the GPRS and the Ethernet’s in practical application. The system uses S3C6410/ARM11 as controller and ZET MF210 wireless module, which is taking in the WCDMA system. The system implements 3G function through the configuration in the embedded Linux system related to drive, transplant the PPP suite, write configuration script and so on. This paper introduces the hardware design, driver transplant, and the realization of the function of network communication process. This solution has the advantages like fast, stable and reliable.
