A low-power gnss deformation monitoring terminal and its power automatic adjustment method

Abstract

The invention discloses a low-power consumption GNSS deformation monitoring terminal and a power automatic adjustment method thereof. The method includes when the working mode is in the normal working mode, acquiring and uploading GNSS monitoring data according to a preset frequency and determining whether the ratio of the current remaining light time to the current voltage of the storage battery is lower than a first preset threshold; The mode is switched to a low power consumption mode; if not, then repeat the step of determining whether the ratio of the current remaining illumination time to the current battery voltage is lower than the first preset threshold; in the low power consumption mode based on the GNSS monitoring When the data determines that there are potential safety hazards in the current environment, the frequency of obtaining and uploading the GNSS monitoring data is increased. The invention realizes the switching of the working mode according to the ratio of the current remaining illumination time to the current voltage of the storage battery, reduces the power consumption during use, and solves the problem of short battery life of the terminal equipment in continuous rainy weather.

Description

technical field [0001] The present application relates to the technical field of global navigation satellite systems, and in particular, to a low-power GNSS deformation monitoring terminal and a power automatic adjustment method thereof. Background technique [0002] GNSS (Global Navigation Satellite System, Global Navigation Satellite System) includes GPS in the United States, Glonass in Russia, Galileo in Europe, and Beidou satellite navigation system in China. The more it can be applied to the monitoring of reservoirs and dams, deep foundation pit monitoring, roadbed monitoring of highways and railways, mine safety monitoring, high-rise building tilt monitoring and power tower monitoring and other fields. [0003] GNSS deformation monitoring terminals are generally deployed at the monitoring site. Considering the ease of installation and low-cost requirements of the equipment, solar power is generally used. The conventional GNSS deformation monitoring terminal has a sing...

AI Technical Summary

Problems solved by technology

The conventional GNSS deformation monitoring terminal has a single working mode and needs to maintain continuous measurement and transmission. The average power consumption is about 5W. During the rainy season, it is prone to power failure and cannot work, causing hidden dangers in safety monitoring

[0004] Therefore, the existing GNSS deformation monitoring terminal has defects such as high power consumption and inability to adapt to stable and long battery life in continuous rainy weather. It is easy to fail to find potential safety hazards in time due to battery life problems, and the actual use effect is not good.
