Referring to FIG. 1 , FIG. 1 is a schematic diagram of a Beidou-based transmission line tower assembly inclination detection device provided by the present application.

The present application provides a Beidou-based transmission line tower assembly inclination detection device, including a transmission line collection terminal 1 , a background data processing terminal 3 and a Beidou communication module 2 . The transmission line acquisition terminal 1 is used to collect and process transmission line data, such as power data, meteorological data, cable sag data and base tower data, etc., wherein the power data includes current, voltage, etc., and the meteorological data includes temperature and humidity, wind power, etc. etc. The base tower data includes inclination, settlement, etc., and the inclination degree of the tower is comprehensively evaluated through power data, meteorological data, cable sag data and base tower data. In order to adapt to the characteristics of Beidou communication and reduce the amount of data transmission, this application moves some intelligent analysis functions forward and deploys them on field terminals to realize edge computing. The background data processing terminal 3 is used to process the background data, and the Beidou communication module 2 is communicatively connected to the transmission line collection terminal 1 and the background data processing terminal 3 for online transmission of collected data to the background data processing terminal.

As shown in FIG. 3 , FIG. 3 is a schematic diagram of the Beidou communication module in FIG. 1 .

In order to ensure the safety of the power infrastructure, and to meet the development of the smart grid for the wide-area grid system status monitoring information transmission, time synchronization and other functions, the Beidou communication module 2 adopts the Beidou system, and its main operation process is: using the field site The monitoring stations (CORS station 23, reference station 24) use wireless communication technology to connect the transmission line terminal with the background data processing terminal 3 . Figure 3 corresponds to the tower tilt monitoring method: deploy the Beidou communication module 2 on the transmission line tower, and establish a CORS reference station in a stable terrain area where settlement or deformation is not easy to occur. The Beidou signal receiver 21 is installed in the CORS reference station to continuously observe the satellites in the survey area, and transmit the observation data and station coordinate information to the monitoring center 22 in real time. The monitoring center 22 receives the differential data transmitted by the CORS station 23, and then processes the data in real time according to the principle of relative positioning, and gives the three-dimensional coordinates of the observation station in real time. Real-time security monitoring.

As shown in FIG. 4 , FIG. 4 is a schematic diagram of the background data processing terminal in FIG. 1 .

The background data processing terminal 3, for each transmission line tower, its monitoring system consists of a Beidou receiver and antenna arranged on the tower, an ARM core board and a continuous operation stable reference station. Arrange a Beidou receiver on the tower as a mobile station, fix its antenna on the top of the tower, and connect the Beidou receiver to the ARM core board through the serial port. The monitoring algorithm uses the Ntrip network protocol to communicate with the CORS station 23 to receive differential data, and writes the data into the Beidou receiver so that the Beidou receiver can perform differential calculation and obtain high-precision positioning information. At the same time, it reads the positioning information output by the Beidou receiver, processes it and calculates the inclination angle, and then sends the result to the host computer for display, so as to realize the monitoring of the inclination angle of the tower. The background data processing terminal 3 in this application has the functions of providing multi-source data integration, report statistics, data visualization, self-service BI analysis, and data filling to help users tap the potential value of data.

The transmission line acquisition terminal 1 collects the required basic information by using a variety of different signal sensor receivers at the signal receiving end, such as current and voltage, line frequency, etc., and the line terminal transmits the collected data to the background data online through satellite signals processing terminal 3, and perform corresponding classification calculations in the background data processing terminal 3. The transmission line acquisition terminal 1 includes a signal sensor receiver for collecting various data respectively, an A/D conversion circuit 11, a liquid crystal control circuit 12, a single-chip microcomputer control circuit 13 and a frequency monitoring circuit, as shown in Fig. 2, Fig. 5 to Fig. 8 Show.

After passing through this circuit, the accurate real-time pole current, voltage, corresponding frequency and other data of the angle corresponding to the current transmission tower pole can be obtained, and the real-time data can be input into the Beidou receiver for combined analysis with the machine tower data, and the difference can be made. Decomposition calculation to obtain high-precision positioning information. At the same time, the positioning information output by the Beidou receiver is read out, and after it is processed and the inclination angle is calculated, the result is sent to the host computer for display, so as to realize the monitoring of the inclination angle of the tower.

Among them, the connection relationship between each circuit is as follows: the AC current and AC voltage are monitored through the signal sensor, and then the voltage and current signal is converted into a digital signal through the A/D conversion circuit, and then transmitted to the single-chip microcomputer behind.

Among them, the A/D conversion circuit converts signals such as voltage value and current value into eight-digit digital signals; the function of the liquid crystal display circuit is to display relevant values such as current, voltage, and frequency in real time; the frequency monitoring circuit realizes the current frequency waveform through an oscilloscope.

Arrange the terminal device on the transmission line tower, and establish a CORS reference station in an area where settlement or deformation is not easy to occur. The Beidou signal receiver 21 is installed in the reference station 24 to continuously observe the satellites in the survey area, and transmit the observation data and station coordinate information to the monitoring center 22 in real time. The monitoring center 22 receives the differential data transmitted by the CORS station 23, and then processes the data in real time according to the principle of relative positioning, and gives the three-dimensional coordinates of the observation station in real time. Real-time security monitoring.

The specific process is shown in Figure 4. For each transmission line tower, its monitoring system consists of a Beidou receiver and antenna, an ARM core board, and a continuous operation stable reference station. A Beidou high-precision receiver is placed on the tower as a mobile station, and its antenna is fixed on the top of the tower. Connect the receiver to the ARM core board through the serial port. The monitoring algorithm uses the Ntrip network protocol to communicate with the CORS station 23 to receive differential data, and write the data into the receiver so that the receiver can perform differential calculation and obtain high-precision positioning information. At the same time, read the positioning information output by the receiver, process it and calculate the inclination angle, and then send the result to the host computer for display, so as to realize the monitoring of the inclination angle of the tower.

The Ntrip protocol is an international standard network protocol for transmitting differential data on the Internet. It was initiated and formulated by the German Federal Bureau of Surveying and Mapping (BKT) in 2004. Ntrip protocol consists of four parts: Ntrip data source (NtripSources), Ntrip client (NtripClient), Ntrip server (NtripSever) and Ntrip processing center (NtripCaster). The software implementation method of the Ntrip client is as follows: Utilize the ARM module to realize the function of the Ntrip client, and send an AT command, establish a socket connection with the CORS station 23 of the specified IP address and port number, after establishing a connection with the CORS station 23, then follow the above-mentioned The format of the request information sends the request information to the CORS station 23. If the request is passed, the differential data can be obtained. After the ARM module reads the differential data, it sends the differential data to the receiver, and the receiver can perform RTK high-precision positioning. In order to ensure that the receiver can always work in RTK mode and output high-precision positioning information, the necessary condition is that it can continuously obtain differential information from the CORS station 23 . Therefore, it is necessary to monitor in real time whether there is differential data all the time, and if the differential data disappears, it is necessary to establish a connection with the CORS station 23 again.

Regarding the acquisition of differential data in this application, the accuracy of tower inclination monitoring can be improved from two aspects: on the one hand, the positioning accuracy of the Beidou receiver is improved; on the other hand, the accuracy of the inclination calculation algorithm is improved. When the Beidou receiver works in RTK mode, the positioning accuracy is the highest, which can reach centimeter level. In RTK mode, the receiver receives the observation information sent from the base station 24 and the position information of the base station 24, collectively referred to as differential information, and then the receiver combines its own observation data to perform differential positioning, that is, relative positioning, thereby greatly improving positioning accuracy . The currently commonly used RTK method is network RTK, and the base station 24 is replaced by a continuously running reference station.
