摘要
传统的海岸信息系统在通信中受到传输数据较多的影响,在传输时常存在数据冗余情况,从而导致信息在传输时出现丢包情况。为此,设计一个基于无线网络的海岸信息系统。系统的硬件部分设计了无线通讯模块、电源模块、单片机和存储模块等,为系统提供通信支持,在系统软件部分,主要对簇头选举与信道分配,以此完成海岸信息系统的设计。通过实验表明,所研究的系统减少了信息的丢包率,并降低了信息系统的通信时延。
The traditional coastal information system is affected by the transmission data in the communication,and there is often data redundancy in the transmission,which leads to packet loss in the transmission of information.Based on this phenomenon,a coastal information system based on wireless network is designed.In the hardware part of the system,wireless communication module,power module,MCU and memory module are designed to provide communication support for the system.In the software part,cluster head election and channel allocation are mainly used to complete the design of the coastal information system.The experimental results show that the system reduces the packet loss rate and the communication delay of the information system.
