The invention provides a tower inclination monitoring device based on NB-IoT network, comprising an angle acquisition chip, a MCU, a NB-IoT communication module, an antenna and a remote server. The angle acquisition chip is a three-axis acceleration sensor, which transmits measured acceleration information to the MCU. The MCU receives the acceleration information transmitted by the angle acquisition chip, calculates a tower inclination by a formula, and transmits to the NB-IoT communication module. The NB-IoT communication module parses the received tower inclination data into wireless signalsand transmits to the remote server via a wireless network using the antenna. The tower inclination monitoring device based on NB-IoT network achieves the power reduction effect of the overall measuring device by using the low-power NB-IoT communication technology and the deep sleep energy-saving technology of the MCU controller. Therefore, the problem of large power consumption of the power transmission tower measuring device and short power supply life is solved, and at the same time, the communication architecture is simplified since the communication module is directly connected to the server.
Description
technical field [0001] The invention belongs to the technical field of transmission line monitoring, in particular to a tower inclination monitoring device based on NB-IoT network. Background technique [0002] A pole tower is a structure used to support conductors and lightning conductors in overhead transmission lines. Power transmission lines are affected by complex environments such as geology, weather, and external forces, which will cause the tower to tilt and collapse. In recent years, power accidents caused by the tilt and collapse of line towers are on the rise. In order to ensure the safe operation of the entire power grid, it is necessary to design an effective tower inclination angle measurement device to monitor the change of the inclination angle of the tower, prevent the toppling of the tower, and avoid the occurrence of electrical accidents. [0003] At present, most tower inclination monitoring devices are based on GSM / GPRS / 3G / 4G communication or wireless L...
