Description

Smart phone support towards bridge vibration monitoring

Technical Field

The invention belongs to the technical field of sensor installation, and particularly relates to a smart phone support for bridge vibration monitoring.

Background

Transportation is an economic life line of a country, and a bridge is a throat of transportation, and the construction and maintenance of the bridge are important components of the infrastructure construction of the country. The bridge often vibrates under the action of external load, and the influence of small vibration on the structure is small under the general condition. However, with the development of traffic demand and the improvement of construction technology in recent years, the span of bridges is leaping, and the number, load and speed of passing vehicles are increased, so that the vibration response of bridges is increased. Catastrophic bridge structure failure accidents due to severe vibration occur. Therefore, in order to effectively evaluate the safe operation state and the service life of the bridge, the development of the continuous monitoring of the vibration state of the bridge becomes an important content in the operation work of the bridge.

The sensor is the basis of structure detection/monitoring, and is mainly used for measuring parameters such as structure acceleration, speed, displacement and the like. The sensors are classified into various types, and when the sensors are classified according to a data transmission method, the sensors can be classified into two types, namely wired sensors and wireless sensors. Wired sensor need combine cable wire work, when being applied to kilometre level bridge, its wiring is very loaded down with trivial details and later stage cable maintenance need consume a large amount of time and energy. Compared with the traditional wired sensor, the wireless sensor has the advantages of flexible arrangement, no need of wiring and the like. However, wireless sensing also has certain limitations, such as insufficient power supply time due to limited battery capacity, and data leakage caused by electromagnetic interference in communication. At present, sensors in a bridge health monitoring system are all fixed sensors, and special processes and instruments are needed to realize the installation and fixation of the sensors on a bridge. For data transmission, a special communication network is often required to be established to transmit data collected in real time on site to a data terminal.

In recent years, mems sensors have become popular and have become one of the important components of smart phones. At present, a smart phone often has various built-in sensors, such as an acceleration sensor, a GPS, a gyroscope, a direction sensor, and the like, which can sense different motions, directions, and external environments in real time. When the position of the smart phone changes, the sensors can accurately acquire three-dimensional space data. In view of its portability and intelligence, a smartphone can be considered as a sensor for monitoring bridge vibrations. When the mobile phone is fixed with the bridge, the physical state of the bridge can be monitored by monitoring the parameters such as displacement, acceleration and the like of the smart phone, and then the health state evaluation of the bridge is carried out. In addition, the mobile phone vibration test data can be uploaded to the cloud through a 4G/5G network so as to be stored and processed in the cloud, and therefore a user can check the mobile phone vibration test data in real time. The transmission mode effectively avoids the problem that special networking is required in the traditional monitoring means, simplifies the monitoring scheme and saves the engineering cost. However, this technology is implemented on the premise that the mobile phone has an effective and reliable connection with the bridge. At present, a smart phone support which is specially used for assisting a mobile phone in vibration monitoring is lacked, and the development of a smart phone support for bridge vibration monitoring is a key problem to be urgently needed.
