Abstract. In order to monitor the scenic spot and transmit the collected data to the users, established the integrated sensing system based on the embedded Linux . Used the sensors to collect the different data and pictures and then they were transmitted by the wired and wireless mode. Set up the small Web server by the Boa (small Web server) and realized the integrated Web technology and CGI (Common Gateway Interface) program. According to the difference information of the scenic spot, the mobile platform collected the needed data and transmitted it to the control platform by the ZigBee wireless module and displayed in the embedded platform. The administrator can realize monitoring all the spots of the scenic and control the terminal equipments in the whole day.

“…WDAQUs acquire data from there connected sensors, send the acquired data to their corresponding BSUs through single hop wireless communication, and receive commands from the CMDU; BSUs serve as the bridge between their corresponding WDAQUs and the computer, passing the data; The CMDU is similar to BSU, but in charge of broadcasting the commands from the computer to WDAQUs, such as starting/stopping data acquisition; The DACS receive, store and plot the data from the BSUs, and provides a convenient and friendly graphical user interface for the user to configure and operate the system. Since this study focuses on the experimental validation, this section only describes the system architecture, features and performance, while the details of the system implementation is presented in (Chen et al 2014). …”

When compared to wired sensor technology, wireless sensor technology often suffers long data collection delay, big noise floor and data loss. Addressing these challenges, a wireless data acquisition system was designed and implemented by the authors. It can provide a performance comparable to the one of a wired data acquisition system. In this paper, the system is validated by its application in the monitoring of a timber pedestrian bridge in Italy. The system features flexible sensor interfaces, high power efficiency, low noise data acquisition, real-time and lossless wireless data transmission, and a convenient graphical user interface. Two field experiments were conducted. In the first experiment, the wireless data acquisition unit was designed to use an unreliable communication mode, resulting in an underestimated data loss problem. In the second experiment, the system is improved. The ACK-RETRIES reliable communication mode and a data packet sequence number checking mechanism are adopted, so that the data loss was avoided. For a comparison, a wired portable data acquisition system VSS-3000 was also used to acquire data from one accelerometer. The results show that the wireless data acquisition system is able to acquire high quality data from low noise sensors in real time without data loss. Compared to the VSS-3000, the data acquired by the wireless sensor platform have a comparable and even better quality.

Abstract. The authors had the chance to collect structural response measurements of a cable-stayed gluedlaminated-timber (GLT) footbridge located in Farra d'Alpago (not far from the town of Belluno, in NorthEastern Italy). A consistent geometrically nonlinear finite element model was generated and its parameters were calibrated on the experimental data. Finally, a model validation was carried out.
