基于Ad-Hoc网络的物联网数据采集系统设计

Design of IoT Data Collection System Based on Ad-Hoc Network

在物联网系统中,需要终端设备采集数据并上传到服务器中进行计算和处理。如果终端设备中的通信模块信号不好或者出现异常情况,使得数据无法及时的上传到服务器中,会极大地影响到系统的正常工作。针对该上传异常情况,提出一种基于Ad-Hoc网络的系统方案。在终端设备原有的网络中增加一个Wi-Fi模块,用于终端设备之间组建Ad-Hoc网络,当一个设备的数据上传模块出现异常时,可以把数据通过Ad-Hoc网络发送到该网络中的其他设备上,并通过其他设备的数据上传模块,把实时数据上传到服务器中。通过测试表明,该方案能够把原来不能上传成功的数据通过Ad-Hoc网络及时上传到服务器中,保障了系统的稳定运行。

This paper proposes a system based on Ad-Hoc network.A Wi-Fi module is added to the original network of the terminal device to form an Ad-Hoc network among the terminal devices.When a device's data upload module encounters an exception,the data can be sent to other devices through the Ad-Hoc network,and the real-time data can be uploaded to the server through the data upload module of other devices.Tests show that this approach can timely upload data that was not successfully uploaded before through the Ad-Hoc network to the server,ensuring the stable operation of the system.
