In the context of the Internet of Things (IoT), sensors enhance the capabilities of buildings and their managers to make them smarter, improving building system performance and predicting demand. Relevant data show that the income of other related industries driven by the snow and ice sports involved in the 2022 Beijing Winter Olympics will reach more than 300 billion yuan. In this 300 billion yuan industrial cake, infrastructure construction is the highlight. At present, more and more sensors are connected to each other and distributed in various types of Winter Olympics infrastructure buildings. These sensors will provide valuable and useful information for facility managers.

At present, Wujiazhuang, in Dingfang Water Township, Xia Garden, Zhangjiakou City, is actively preparing for the tourist crowd to be greeted by the 2022 Winter Olympics. In the village head, a professional team built a 30 square meter tourist reception center. Don't look at this small tourist reception center is not particularly eye-catching, it is an intelligent cabin using sensor technology.

This small tourist reception center, usually functions as a tourist reception, souvenir sales, and it becomes a stage for performances every festival or big event. It is an openable and detachable cabin. The building is designed with a quasi-crystal structure of the unit cell as the shape of the cabin. It is an irregular 16-faced body with three surfaces equipped with mechanical means to open and close.

In addition, the building is an interactive building that changes shape as the climate changes. So, how is the realization of the opening and closing action of the cottage realized? There is a need for ubiquitous sensor monitoring technology.

It is understood that the opening and closing of the cabin mainly relies on the interactive system installed in the building, which includes the following three subsystems.

The first is the sensor system that collects environmental information, such as temperature sensor, humidity sensor, wind sensor, etc., followed by the software central control system, which is responsible for calculating the collected information according to the set requirements, and issuing instructions; A mechanical device on three panels that, when the system receives an instruction from the hub, performs a command to push the panel to the appropriate position. When the three panels of the cabin were fully opened, it became a stage for performances, and the audience sat on the slopes of the surrounding slopes to watch the performance freely.

When the outdoor temperature is between 16 and 29 degrees Celsius, the temperature and humidity sensor in the sensor system can accurately monitor the temperature change, the data is transmitted to the central control system, and then the mechanical device is activated, so that the three panels can be opened at different angles to ensure The building has natural ventilation and views of the outdoor. Similarly, when the outdoor temperature is lower than 16 degrees Celsius, the temperature and humidity sensor will also be quickly perceived. After the sensor data is transmitted to the other two systems, the three panels will be automatically closed and the coiled device will be started at the first time. Floor heating system for heating. In addition, when the outdoor temperature is higher than 29 degrees, the three panels will automatically close and start the air conditioning system for cooling; when it is windy or rainy, the three panels will also be closed to prevent weather erosion.
