基于串口通信实现内外网水情数据的自动传输

Automatic transmission of hydrological data from intranet to extranet based on serial communication

水文部门及时向各级防汛部门和社会发布水情信息,为政府对水资源的社会管理和公共服务职能提供全面优质的服务。由于安全需要,水情信息多放在水文内网中,水文内网与因特网常采用物理隔离,水情信息无法及时利用因特网向各级防汛部门和社会发布。笔者介绍了一种基于串口通信、不使用任何网络协议、比网闸隔离更彻底的内外网数据传输方式,实时将水文内网中的水情数据更新到外网的数据库中,为水情信息的发布提供自动、及时、准确的数据支撑,向社会提供可靠的水文服务。

Hydrology is a basic public welfare undertaking in the economic and social development. The comprehensive quality hydrological service should be provided to the government for social management of water resources and the public service functions. Hydrological information should be released to the flood control departments at all levels and society. Due to Security need,hydrological data is in hydrologic intranet. Hydrological intranet and the Internet often use physical isolation. Hydrological information in hydrologic intranet cannot be timely released to the flood control departments at all levels and social. A method of data transmission to send hydrological data from hydrological intranet to the Internet based on serial communication without using any network protocol is introduced in this paper. It is more thoroughly than the net gap. It can provide automatic,timely,accurate data support for the release of hydrological information. The reliable hydrological services can be provided to the society.
