6 FAQs about [Solar road monitoring power supply system]
Can a photovoltaic standalone system be used as a power supply unit?
In this paper, the most used EHTs in the field of road infrastructures were analyzed and, among them, a photovoltaic standalone system (PVSS) was selected and considered as the power supply unit of an electronic structural health monitoring (SHM) system.
Where is the power supply system located?
The power supply system, harnessing solar and wind energy, is located adjacent to the road and powers both the gateway and sensors. The primary sources of power are solar energy and battery supply, opting for a 450 W solar panel in conjunction with a solar energy management module responsible for power conversion and battery charging.
What is a pavement monitoring system?
Existing pavement monitoring systems are usually installed in already-serviced roads, requiring methods like cutting and grooving to embed sensors, which can cause significant damage and reduce the service life of the pavement. Moreover, existing systems typically monitor a single parameter, such as temperature, humidity, vibration, or imagery.
What is a smart road infrastructure system?
The smart road infrastructure system encompasses pavement materials and structures, a sensory network (comprising sensors and a gateway), a communication network, a power supply system, and a cloud platform (featuring a remote server and visual interface), as illustrated in Fig. 2. Fig. 2.
How long does a solar monitoring system last?
This battery not only boasts a lifespan of at least five years but can also be easily replaced, effectively reducing maintenance costs and complexities. By harnessing solar power, the monitoring system can self-sustain in remote areas without the need for external power lines, reducing costs and enhancing deployment convenience. 3.
How is road vibration monitoring data organized?
The monitoring data is organized in files, with each file containing data collected over 10 s. Initially, the raw data within each 10-s period undergoes a baseline calibration. The average value of the 10-s data is used as a baseline, and the raw data is adjusted by subtracting this average value to obtain the calibrated road vibration data.
