[0002] Jiangxi belongs to the subtropical humid monsoon climate zone, with abundant precipitation, frequent rainstorms and floods. The complex terrain and changeable climate conditions have made Jiangxi a high-incidence area for natural disasters such as low temperature freezing, wind and hail, floods, typhoons, as well as geological disasters such as landslides, collapses, mudslides, and ground subsidence. These disasters often cause problems such as overall tilt, collapse, and slippage of the foundation of power towers of transmission lines, especially in areas where power towers are widely distributed and cross complex terrain. In order to solve these problems, an intelligent terminal and early warning system for power tower settlement monitoring based on Beidou carrier phase difference technology is proposed. Summary of the invention

It combines satellite maps to display transmission line and tower information, judges and warns the status of power towers, generates tower status trend graphs, and realizes real-time online monitoring of tower status.

[0009] Furthermore, the magnetostrictive level meter is installed on the four legs of the power tower by welding, and is powered by pulling wires to observe vertical displacement. According to changes in the external magnetic field, the change value of the internal measuring material is converted into an electrical signal to measure the displacement.

[0010] Furthermore, the Beidou differential positioning tilt measurement module realizes high-precision tilt measurement through GNSS and inertial navigation fusion algorithm.

[0011] Furthermore, the inclination measurement accuracy of the Beidou differential positioning inclination measurement module is less than or equal to 2.5cm, and it supports a maximum inclination measurement of 60°.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0023] like Figure 1 As shown, the present invention provides a power pole tower settlement monitoring system based on Beidou differential positioning technology, including a data acquisition unit, a wireless gateway, and a server. The data acquisition unit transmits the collected data to the wireless gateway wirelessly, and the wireless gateway transmits the data to the server, wherein the data acquisition unit is used to collect the data of the power pole tower and send it to the server through the wireless gateway, and the server is used to process the received power pole tower data, judge the status of the power pole tower, and issue early warning information and alarm information.

[0024] In the present invention, the data acquisition unit is composed of a magnetostrictive liquid level meter, a Beidou differential positioning inclination measurement module, a satellite signal receiver, a power supply module, a communication module, etc., wherein the Beidou differential positioning inclination measurement module and the power supply module are integrated on the satellite signal receiver, and the data collected by the magnetostrictive liquid level meter and the satellite signal receiver are transmitted to the wireless gateway through the communication module, and then transmitted to the server through the wireless gateway.

[0025] In the present invention, the magnetostrictive liquid level meter is used to measure the displacement by converting the change value of the internal measuring material into an electrical signal according to the change of the external magnetic field. When in use, the magnetostrictive liquid level meter is installed on the four legs of the power tower by welding connection, and power is drawn by pulling wires to observe the vertical displacement.

[0026] In the present invention, the Beidou differential positioning tilt angle measurement module is integrated on the satellite signal receiver and installed on the top of the power tower to monitor the tilt angle and three-dimensional coordinate displacement. The Beidou differential positioning tilt angle measurement module realizes high-precision tilt measurement through the GNSS and inertial navigation fusion algorithm. The tilt angle measurement accuracy is less than or equal to 2.5cm, and the maximum supported tilt angle measurement is 60°. The Beidou positioning vertical accuracy error is less than or equal to 15+D*10-6mm, and the horizontal accuracy error is less than or equal to 8+D*10-6mm.

[0027] In the present invention, the power supply module is powered by solar energy and is integrated on the satellite signal receiver to supply power to the system.

[0028] The system of the present invention adopts a B / S structure and is developed using Java, Python, and JavaScript languages. It combines satellite maps to display transmission line and tower information, mainly including basic information of power towers, vertical displacement data display, and inclination data display. By comparing and calculating the above data and changes in three-dimensional coordinate data, the status of the power tower is judged and warned, and a tower status trend diagram is generated to achieve real-time online monitoring of the tower status.

[0029] The working process of the system of the present invention is as follows:

[0030] Firstly, the magnetostrictive level meter is used to obtain the displacement data of the four corners of the power tower, and the Beidou differential positioning inclination measurement module is used to measure the inertial navigation inclination data and three-dimensional coordinate data. The server calculates the displacement change simulation diagram of the tower model image, the displacement change trend curve, and the implemented displacement curve, thereby generating a tower status trend diagram, and generating early warning information and alarm information.

[0031] Compared with other conventional settlement information collectors, the magnetostrictive liquid level meter of the present invention is more stable and more accurate, and is connected to the pole tower through a hard link, so it has stronger stability.

[0032] The present invention utilizes the Beidou differential positioning module when measuring the inclination angle, and does not need to install a reference station. After communication, the position can be corrected by satellite, thereby increasing the inclination angle measurement function.

[0033] The present invention collects settlement, inclination, and Beidou three-dimensional coordinate data to model the tower change trend diagram and predict the state image of the tower after a period of time;

[0034] The system of the present invention is configured to issue a red alarm if the settlement, displacement and tilt data of the tower change significantly within 10 minutes; an orange warning if interval vibration occurs within 24 hours; and a main yellow warning if the settlement, displacement and tilt acceleration of the tower increase according to the trend analysis of the tower.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
