Wireless communication system, detection device and building structure

Abstract

The invention discloses a wireless communication system, a detection device and a building structure. The wireless communication system comprises a transmitting module and a receiving module which areembedded in the building structure. The building structure comprises a steel bar. The transmitting module comprises a signal generator, a first power amplifier, a modulation and coding device and a first coil matched with the steel bar. The receiving module comprises a second power amplifier, an analog-to-digital converter, a demodulation and decoding device and a second coil matched with the steel bar. When the first coil and the second coil are wound on the steel bar, the first coil and the second coil are coupled through the steel bar, and signals emitted by the signal generator sequentially pass through the first power amplifier, the modulation and coding device, the first coil, the steel bar, the second coil, the second power amplifier and the analog-to-digital converter and are inputted to the demodulation and decoding device. The wireless communication system has the advantage of high reliability.

Description

technical field [0001] The invention relates to the technical field of building structure detection, in particular to a wireless communication system, a detection device and a building structure. Background technique [0002] Health monitoring of building structures is a relatively new field of technology. Real-time detection of changes in internal parameters of bridges, houses, roads and other building structures can inform the health status of building structures in advance and prevent safety accidents such as building structures from collapsing. [0003] By embedding sensors in the building structure, the parameters inside the building structure can be detected in real time, and combined with the communication system, the parameters inside the building structure can be sent to external devices. [0004] The existing communication schemes are as follows: [0005] The first type: the transmitting module is connected to the receiving module wirelessly, and the signal sent ...

AI Technical Summary

Problems solved by technology

The disadvantage of this solution is: because the transmitting module is embedded in the building structure, the signal sent by the transmitting module needs to pass through the reinforced concrete during the transmission process, and the loss is relatively large. At present, the wireless module is in the radio frequency and microwave frequency bands, which cannot penetrate obstacles Objects (soil, concrete), and the steel structure in the building will form a Faraday cage effect, further hindering the propagation of electromagnetic wave signals

The disadvantage of this scheme is: when the building structure is damaged, the power line will also be damaged (for example, when the building structure encounters an earthquake or a strong impact, the power line may be torn off), resulting in interruption of the receiving module receiving signal, and poor reliability
