Device, system and method for monitoring power transmission tower based on NB-IOT

Abstract

The invention relates to a device, system and method for monitoring a power transmission tower based on NB-IOT. The device is mounted on a surface of the power transmission tower and is linked with the power transmission tower. The device includes a processor, an MEMS sensor, a carrier phase measurement unit, and a network transmission unit. The MEMS sensor is used for measuring the current attitude information of the MEMS sensor, and transmitting the measured current attitude information to the processor. The carrier phase measurement unit is configured to measure an obtained carrier phase observation value, and sending the carrier phase observation value to the processor. The processor is used for obtaining the attitude offset according to the comparison of the received current attitudeinformation sent by the MEMS sensor with the initial attitude information and determining whether the attitude offset exceeds a preset offset or not, and the alarm information is sent to a server through the network transmission unit, and the attitude offset and the relative position are uploaded to the server. The device, method and system solve the problem that a manual inspection and maintenance mode cannot meet the requirements of the urgency and timeliness of grid line inspection, and achieve all-weather detection.

Description

technical field [0001] The present invention relates to the field of communication equipment, in particular to an NB-IoT-based transmission tower monitoring device, system and method. Background technique [0002] Existing monitoring of high-voltage transmission lines adopts the method of patrol inspection, mainly based on manual visual inspection and helicopter aerial survey. The artificial visual inspection method is patrolled by inspection staff along the line. The inspection method has low precision, high labor intensity, and low efficiency. The helicopter aerial survey method uses helicopters to inspect along the line, and uses cameras and its detection technology to conduct inspections on transmission towers. The cost is high. There are flight hazards. None of the above can solve the problem of all-weather detection of transmission tower deformation.
