Bridge monitoring data acquisition instrument

Abstract

The invention relates to a bridge monitoring data acquisition instrument. The bridge monitoring data acquisition instrument comprises a chip, diodes, a display, a DTU data transmission module, a special output power interface, a conventional output power and 485 signal interface and a power supply, wherein the power supply, the display, the DTU data transmission module, the conventional output power and 485 signal interface and the special output power interface are connected with the chip through the diodes; the DTU data transmission module is connected with the Internet by virtue of a mobile base station or a unicom base station and connected to a server system with a fixed IP address; and the special output power interface and the conventional output power and 485 signal interface are externally connected with bridge monitoring equipment. Owing to the modular integrated design, on the one hand, two power supply modes, namely a mains power supply mode and a solar power supply mode, are realized to achieve flexible power supply modes, on the other hand, the functions of manual data acquisition frequency intervention, manual remote parameter configuration and the like are achieved, and the bridge environment monitoring demand is actually met. The bridge monitoring data acquisition instrument is high in practicability, good in using effect and convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to a bridge monitoring data acquisition instrument. Background technique [0002] With the advancement and coverage of large-scale bridge construction, people pay more and more attention to the health and safety of bridges after they are completed, and some important indicators that affect bridge safety are our focus, such as various parameters that represent the condition of the bridge, stress ( Strain), deformation (deflection), crack, inclination, temperature, wind speed, displacement, etc. In recent years, bridge monitoring with remote parameter configuration has attracted more and more attention. Many enterprises and research institutions at home and abroad have made great progress in the research and development of various bridge parameter sensors. The direction of parameter detection is developing rapidly. However, the communication between the current wireless mon...

AI Technical Summary

Problems solved by technology

However, the communication between the current wireless monitoring module and the host module is only one-way, that is, it is transmitted from the data acquisition module to the host, and the remote control from the host to the data acquisition device is seldom, which requires manual intervention to stabilize the control of each parameter. It is inconvenient, if the data collection frequency can be manually set and combined with remote parameter configuration, it will have a wide range of application prospects
