Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] Such as figure 1 As shown, a disaster warning information publishing and display system applying bandwidth adaptive technology includes a meteorological center server and a terminal device for distributing disaster warning information. The terminal device is provided with an operating program for disaster warning information publishing. It includes a mobile terminal and a PC connected to the Internet. It is characterized in that it also includes a bandwidth adaptive module that automatically adjusts the transmission mode and its transmission parameters according to the network environment. The bandwidth adaptive module first judges the terminal when the application program of the terminal device is running. Whether the device is connected to the Internet through Ethernet or WIFI, or through a mobile communication network, if the terminal device i...

The invention discloses a disaster early warning information publishing and display system using bandwidth self-adaptive technology, including a meteorological center server and a terminal device for distributing disaster early warning information. The device includes a mobile terminal and a PC connected to the Internet. It is characterized in that it also includes a bandwidth adaptive module that automatically adjusts the transmission mode and its transmission parameters according to the network environment. The bandwidth adaptive module first judges when the application program of the terminal device is running. Whether the terminal equipment is connected to the Internet through Ethernet or WIFI, or through a mobile communication network, the disaster warning information distribution system can guarantee the transmission success rate and transmission speed no matter what network environment it is in, and avoid failure due to communication failure. Receive urgent release alert messages.
Description
technical field [0001] The present invention relates to a disaster early warning information release and its display system; in particular, it is a data transmission control technology based on TCP / IP, which automatically adjusts communication parameters by checking the current state of the network, ensures the stability of communication and optimizes the speed of data transmission, Disaster early warning information release and multimedia display system that greatly utilizes network bandwidth. Background technique [0002] At present, network communication based on the widely used TCP / IP lacks control means, and directly uses the SOCKET interface provided by the system to communicate. Therefore, the communication efficiency in various network environments is quite low. If some use broadband networks (such as Optical fiber, gigabit network, etc.) bandwidth utilization rate is not high, while using narrowband communication (such as GPRS) often fails to transmit data. [0003...
