基于物联网技术的建筑工程电能数据采集方法
Power Data Acquisition Method of Construction Project Based on IOT

针对建筑工程中存在的低信号空间内电能数据采集困难的问题，提出了一种基于射频技术(窄带物联网)与多协议通讯的数据传输方法。该方法采用多径自适应组网方式，基于433 MHz射频传输技术，对物理层、数据链路层进行优化，降低系统功耗；再建立基于多协议的通讯模式，实现电能数据远程采集管理。以地下空间数据采集为例，实验验证能够通过该种方式实现数据精准、快速地传输。
According to transmission failure of power data acquisition in the low signal area of the construction project, a low-power-consumption and Ad-Hoc-Network remote data transmission method based on narrowband IOT and multi-protocol technology is proposed. This method adopts the multi-path & self-adaption Ad-Hoc-Network mode, and optimizes the design of the physical layer and data link layer using 433 MHz radio frequency wireless transmission technology, thereby reducing the power consumption of the system and realizing the data transmission in a low signal area; and then, the system realizes the remote collection and management of power data by establishing IOT communication mode based on multi-protocol. This paper takes the underground power data remote collection as an example, the experimental results show that this method can achieve fast, accurate, low-power, and efficient data transmission.
