Bridge health detection and monitoring
Bridge structural health monitoring is an active defense method based on sensors, which can make up for the shortcomings of structures with very important safety performance at present. Putting sensor networks in bridges, buildings and airplanes and using sensors for SHM can detect the formation of defects in the first time, which is a reliable and cheap method. This kind of network can report the defects in key structures to maintenance personnel in advance, thus avoiding catastrophic accidents.
Temperature and humidity monitoring of granary
Wireless sensor network technology is widely used in the field of temperature and humidity monitoring of grain depot. This is because there are many temperature and humidity measuring points in the grain depot, which are widely distributed, and the use of criss-crossing signal lines will reduce the fire safety factor. The application of wireless sensor network technology has the characteristics of low power consumption, low cost, simple wiring, easy installation, easy networking, easy management and maintenance.
Concrete pouring temperature monitoring
In the process of concrete construction, the digital temperature sensor is installed in the metal sleeve with good thermal conductivity, which can ensure the sensor to respond quickly to the temperature change of concrete. Each temperature measuring metal tube is connected with a wireless temperature node, and the wireless temperature node of the whole site is transmitted to the construction monitoring center through a wireless network, so that it is not necessary to lay a long cable on the construction site, which is convenient to install and lay, and can effectively solve the problem of low survival rate of temperature measuring points caused by cable damage by construction personnel.
Earthquake monitoring
By using a sensor network composed of a large number of interconnected micro-sensor nodes, uninterrupted high-precision data acquisition can be carried out in different environments. Using low-power wireless communication module and wireless communication protocol can prolong the life of sensor network for a long time. And the practicability of the sensor network is ensured.
Compared with traditional networks, the most obvious characteristics of wireless sensor networks can be summarized in six words: "self-organization and self-healing". These characteristics enable wireless sensor networks to adapt to the complex and changeable environment and monitor the harsh environmental areas that are difficult for human beings to reach. BEETECH wireless sensor network nodes are small in size and do not need on-site power supply, which is very convenient for flexible deployment, monitoring and prediction of geological disasters in emergency.
Building vibration detection
The cantilever part of the building will not exceed the comfort requirement because of the vibration caused by the traffic of the nearby roads and subways; Through field measurement and data collection, the relationship between the vibration caused by highway and subway traffic and the cantilever vibration of the main building is verified. ? At the same time, the damping ratio of the first few modes of the main structure of the building under the condition of small amplitude pulsating vibration is obtained through modal analysis, which provides key data for the small amplitude dynamic analysis of the structure in the future.
There are many application examples of wireless sensors, which have a wide range of applications and play a vital role in modern urban construction and other important fields. With the application of wireless sensors, we can also see that the progress of science and technology has a profound impact on people's modern life. Technology can make people's lives more convenient and know more about the update of information. The above is the application of wireless network introduced by Bunny. I hope it will help you.
