| 为解决国内部分设施农业园区地处偏远,急需远程监控,但有线网络接入成本高,多数设施所在地区有线网络接入困难的问题,基于3G(the 3rd Generation)无线上网卡+无线路由器的无线通信模块,采用VPN(virtual private network)技术、PPTP(point to point tunneling protocol)技术等设计具有通用性、部署方便、成本低、通信线路长时间稳定的远程监控系统。该系统解决了3G私有IP寻址困难的问题,为设施农业数字化技术应用提供了高带宽且价格低廉的双向无线网络解决方案。实际应用结果表明:该系统可从Internet远程监测基地环境参数,调控基地服务器设备及观看到流畅清晰的实时视频(视频服务器码率预设为512 kbit/s)。 |

| Abstract: |
| A remote monitoring and control system based on 3G+VPN was designed and implementation to meet the remote video monitoring requirement in protected agriculture.It provides a sufficient video bandwidth and cheap wireless network access solutions.Results show that the system has characteristics of high universality,low cost,good expansibility and high reliability;and can be easily applied to the sites of protected agriculture,where there is no wire network connected to Internet,to meet the needs of remote monitoring and control.Now this system has been put into use in school experimental base,through which we can monitor environmental parameters remotely,control base server device,and watch the smooth clear real-time video (video server code rate for 512 kbit/s preset). |
