سیستم شبکه ادهاک جمع آوری داده ها بر اساس حسگر بی سیم Data acquisition ad hoc network system based on wireless sensor

1 Introduction In recent years, with the continuous combination of wireless sensor networks and big data technology, the intelligent building system has gradually entered a new stage of development. Wireless sensor network technology is gradually improving the level of intelligent building, and constantly enriches the intrinsic value of intelligent building. With the development of high integration digital devices, the sensor nodes with low cost and small size are gradually appearing and widely used in the buildings [11]. Wireless sensor network is closely linked with people’s life in the environmental monitoring. In buildings, monitoring environment information can not only provide data support for energy consumption analysis, but also analyze the change of environment and predict the environmental pollution trend [9]. In terms of building energy consumption monitoring, building energy consumption accounts for a large proportion of energy consumption in China. With the increase of total building in China, the proportion of building energy consumption will be greater. Every year, 99% of the buildings in China are high energy consumption buildings, and only 4% of the 43 billion square meters of buildings in China have adopted energy-saving measures. According to this rate, in the near 2020, the energy consumption of the building will be 2 times more than it is now. In the construction industry, energy consumption is mainly concentrated in the summer heating, winter air conditioning and refrigeration electrical equipment, lighting and other aspects. Through the collection, analysis and processing of data in the building environment, using the optimization algorithm obtains the optimal point under the special constraints, which can provide strategy to reduce energy consumption [10]. The traditional building energy consumption monitoring uses the wired connection way namely connected the sensor nodes with the detection center by cable connection. The disadvantage of this way is that the cost is high, the installation cost is very large, and the reliability is poor. As time goes on, the line will gradually become old, and the signal will not be able to provide reliable and effective data by the influence of the line [6]. Wireless sensor network effectively overcomes the shortcomings of traditional building energy consumption monitoring. By building wireless sensor nodes in the building monitoring area, it can accurately, efficiently and real-time collect the building environment information data by self-organizing networking.
