Abstract

The invention discloses an iron tower operation state monitoring system based on GNSS satellite signals. The system comprises a first active receiving antenna and a second active receiving antenna which are arranged on an iron tower, a GNSS signal receiving module connected with the first active receiving antenna and the second active receiving antenna, and a base band calculation module connectedwith the GNSS signal receiving module, wherein the base band calculation module is connected with a monitoring platform, the base band calculation module comprises a digital sampling module and a differential coherent measurement calculation device, and the first active receiving antenna and the second active receiving antenna are arranged on the same measuring end face. The monitoring system isused for carrying out double-antenna receiving through navigation pseudo-range signals and carrier phase signals, and achieves precise measurement through differential coherent measurement to monitorthe iron tower.

Description

technical field [0001] The invention relates to the technical field of state monitoring of steel tower structures, in particular to a GNSS satellite signal-based monitoring system for the running state of iron towers. Background technique [0002] The iron towers used for power transmission or signal transmission are spread all over the place, and sometimes they have to pass through mountains, deserts, lakes and rivers. When passing through these areas, sometimes the environmental conditions will be more complicated and maintenance will be very difficult, but it is necessary to ensure power supply or signal Transmission is extremely important. It is not only closely related to industrial and agricultural construction, but also closely related to people's daily life. If there is a problem with power supply or signal transmission, it is hard to imagine how much impact it will have on society. For this reason, it is particularly important to ensure the safe operation of the abo...
