This paper presents two innovative wireless network designs for the automation system of the Sof-Algeen water station in Zintan, addressing the challenge of connecting field instruments-such as pressure switches, solenoid valves, and differential pressure sensors-over distances of up to 4 km. Due to high costs, limited flexibility, and scalability concerns, traditional hardwired solutions are impractical for such distances. A comprehensive analysis of various Industrial Internet of Things (IIoT) network designs determined that the IEEE 802.11 standard and Phoenix Contact's Trusted Wireless technology best meet the project's requirements for long-distance connectivity, real-time data acquisition, system compatibility, and compliance with national telecommunications regulations. This study proposes optimal network designs using the IEEE 802.11 standard and a hybrid mesh and star network for Trusted Wireless, and evaluates these technologies based on performance, reliability, and infrastructure compatibility using simulation. The network designs were validated using the Radio Mobile tool, considering the water station's specific terrain and wireless module parameters. The findings indicate distinct differences in structure, operation, and cost-effectiveness between the two proposed solutions, highlighting the benefits of each in achieving optimal link feasibility for robust water station automation.
本文介绍了针对赞坦Sof-Algeen水厂自动化系统的两种创新无线网络设计，解决了连接诸如压力开关、电磁阀和差压传感器等现场仪器长达4公里距离的挑战。由于成本高、灵活性有限以及扩展性问题，传统的硬线解决方案对于如此远距离是不切实际的。对各种工业物联网（IIoT）网络设计的全面分析确定，IEEE 802.11标准和菲尼克斯电气的可信无线技术最符合该项目对长距离连接、实时数据采集、系统兼容性以及符合国家电信法规的要求。本研究提出了使用IEEE 802.11标准以及针对可信无线的混合网状和星形网络的最优网络设计，并通过仿真基于性能、可靠性和基础设施兼容性对这些技术进行评估。考虑到水厂的特定地形和无线模块参数，使用Radio Mobile工具对网络设计进行了验证。研究结果表明，两种提议的解决方案在结构、运行和成本效益方面存在明显差异，突出了每种方案在实现稳健的水厂自动化最优链路可行性方面的优势。
