Structure online monitoring system based on NB-IoT protocol

Abstract

The invention discloses an NB-IoT protocol-based structure online monitoring system, which comprises a sensor module, a sensor collection and processing module, an NB-IoT data communication module, a power supply charging and power supply management module, a server side and a client terminal, and is characterized in that the sensor module obtains data through measurement, the sensor collection and processing module receives the data and sends the data to the NB-IoT data communication module; the NB-IoT data communication module is arranged at the front end, the server side is arranged at the rear end, the sensor collection processing module remotely transmits data to the server side through the NB-IoT data communication module, the power supply charging and power supply management module provides power supply, and online monitoring data display, storage and analysis management software is arranged at the server side. the monitoring data are displayed in a classified manner and stored as required, and online analysis is performed in real time, and early warning information is given. According to the invention, wiring is not needed, the cost is reduced, the power consumption is smaller, the telecom operator-level service quality can be provided, and the method can be conveniently applied to a complex structure monitoring environment.

Description

technical field [0001] The invention relates to the technical field of online structural monitoring systems, in particular to an online structural monitoring system based on the NB-IoT protocol. Background technique [0002] With the advancement of science and technology and the needs of transportation, many large bridges and other structures have emerged as the times require. Especially, suspension bridges are favored because of their large spans, beautiful shapes, and low cost. They have become the first choice for bridge design and construction. However, due to the lack of necessary monitoring and maintenance, there have been some bridge damage accidents in our country, which have caused huge losses to the national economy and people's lives and property. At present, there are various monitoring systems based on Internet of Things connection technologies such as Zigbee, Lora and other low-power chip networking on the market, but these chips cannot achieve long-distance co...

Problems solved by technology

However, due to the lack of necessary monitoring and maintenance, there have been some bridge damage accidents in our country, which have caused huge losses to the national economy and people's lives and property.

At present, there are also various monitoring systems based on Internet of Things connection technologies such as Zigbee, Lora and other low-power chip networking on the market, but these chips cannot achieve long-distance communication, and the system composition is complex, requiring additional relay gateways

With the development of smart cities, the real-time and long-term requirements of various structural monitoring are increasing in the future. Not only bridges need to be monitored, but also all kinds of high-speed rail lines, dams, houses, elevated structures and other structures must be monitored online to ensure early monitoring. To predict the risk of damage, the existing scheme is difficult to meet such a wide range of applications and development, so a structure online monitoring system based on NB-IoT protocol is proposed
