Distributed bridge wireless communication measurement system

Abstract

The invention relates to a distributed bridge wireless communication and measurement system, which comprises a data collection device, a data transmission device, a data transmitting and receiving device and a wireless communication method. The system data collection device is arranged at the bottom of a bridge or at the measuring point opposite to the wireless closed region, and can digitize the signals of a measurement object. And the data transmitting device can be used for transmitting the collected measuring data to the data transmitting and receiving device by the digital wireless communications. The distributed bridge wireless communication and measurement system realizes the wireless communications by the wireless transmitter. Since the invention adopts a distributed system, and the data collection device is arranged at the measuring point for the digitized conversion in site, the interference caused by cables arranged in the prior art can be reduced, thereby greatly saving time and cost during the measurement and improving the working efficiency, the measuring data of the measuring point can be converted in the digitized way, thereby guaranteeing the accuracy, reliability and stability of the measurement.

Description

【Technical field】 [0001] The invention relates to a bridge wireless communication measurement system, in particular to a distributed bridge wireless communication measurement system capable of measuring the bottom of a bridge. 【Background technique】 [0002] After the bridge is completed, a set of measurement system is needed to monitor the condition of the bridge. The bridge monitoring point is generally at the bottom of the bridge. The current measurement is generally for data transmission through wired methods. Since the measurement point is set at the bottom of the bridge, only the data signal of the measurement point is led to the bridge deck with a cable, and then the data recording system on the bridge deck records the signal, and then analyzes it to monitor the condition of the bridge. [0003] However, due to the use of wired cables to transmit signals over long distances, the signal is lost and distorted, and the signal is also susceptible to interference, which af...

Problems solved by technology

[0003] However, due to the use of wired cables to transmit signals over long distances, the signal is lost and distorted, and the signal is also susceptible to interference, which affects the accuracy and stability of the measurement.

At the same time, the consumable use of a large number of cables makes the project cost high

[0004] If wireless communication is used to transmit signals, and because bridges are mostly made of metal, reinforced concrete or other materials that have the effect of isolating, shielding and attenuating wireless, in general, the bridge deck and the working surface of the bridge bottom measurement point cannot , or unable to perform wireless communication normally
