Referring to fig. 1, fig. 1 is a schematic diagram of a transmission line tower assembly inclination detection device based on Beidou provided by the application.
The application provides a transmission line shaft tower assemblage slope detection device based on big dipper, including transmission line acquisition terminal 1, backstage data processing terminal 3 and big dipper communication module 2.

The background data processing terminal 3 is used for processing background data, and the Beidou communication module 2 is connected with the power transmission line acquisition terminal 1 and the background data processing terminal 3 in a communication mode and used for transmitting collected data to the background data processing terminal on line.
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 electric power infrastructure and meet the requirements of the development of the intelligent power grid on functions such as wide area power grid system state monitoring information transmission and time synchronization, the Beidou communication module 2 adopts a Beidou system, and the main operation process is as follows: the transmission line terminal and the background data processing terminal 3 are connected by a monitoring station (a CORS station 23, a reference station 24) in the field using a wireless communication technology. Fig. 3 corresponds to a tower tilt monitoring method: the Beidou communication module 2 is arranged on a transmission line tower, and a CORS reference station is established in a terrain stabilization area in which settlement or deformation is not easy to occur. The Beidou signal receiver 21 is arranged in the CORS reference station, continuously observes satellites in the area, and transmits 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, processes the data in real time according to the relative positioning principle, gives out the three-dimensional coordinates of the observation station in real time, and the monitoring center 22 calculates the gradient of the tower in real time, thereby realizing real-time safety monitoring of the tower.
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 power transmission line tower, the monitoring system thereof comprises a Beidou receiver and antenna which are arranged on the tower, an ARM core board and a continuous operation stable reference station. A north bucket receiver is arranged on a pole tower and used as a mobile station, an antenna of the north bucket receiver is fixed at the top of the pole tower, and the Beidou receiver is connected with an ARM core board through a serial port. The monitoring algorithm utilizes the Ntrip network protocol to communicate with the CORS station 23 to receive the differential data, and writes the data into the Beidou receiver so that the Beidou receiver performs differential calculation to obtain high-precision positioning information. And simultaneously, the positioning information output by the Beidou receiver is read, and after the positioning information is processed and the inclination angle is resolved, the result is sent to an upper computer for display so as to realize the monitoring of the inclination angle of the tower. The background data processing terminal 3 in the application has the functions of providing multi-source data integration, report statistics, data visualization, self-service BI analysis, data filling and the like, and helps users to mine potential value of data.
The transmission line acquisition terminal 1 collects required basic information, such as current and voltage, line frequency and the like, by using a plurality of different signal sensor receivers at a signal receiving end, the line terminal transmits the collected data to the background data processing terminal 3 on line through satellite signals, and the background data processing terminal 3 performs corresponding classification calculation. The power transmission line acquisition terminal 1 comprises a signal sensor receiver, an A/D conversion circuit 11, a liquid crystal control circuit 12, a singlechip control circuit 13 and a frequency monitoring circuit for respectively collecting various data, as shown in fig. 2 and 5-8.
The accurate real-time line pole current, voltage, corresponding frequency and other data of the angle corresponding to the current power transmission tower pole can be obtained after the circuit is passed through, real-time data are input into the Beidou receiver to be combined and analyzed with the tower data, differential calculation is carried out, and high-precision positioning information is obtained. And meanwhile, the positioning information output by the Beidou receiver is read out, and after the positioning information is processed and the inclination angle is calculated, the result is sent to an upper computer for display so as to realize the monitoring of the inclination angle of the tower.
Wherein, the connection relation among each circuit is as follows: the alternating current and the alternating voltage are monitored through a signal sensor, then the voltage and current signals are converted into digital signals through an A/D conversion circuit, and the digital signals are transmitted to a singlechip at the back.
The A/D conversion circuit converts signals such as voltage values, current values and the like into eight-bit digital signals; the liquid crystal display circuit has the function of displaying relevant values such as current, voltage, frequency and the like in real time; the frequency monitoring circuit implements the current frequency waveform through an oscilloscope.
The terminal device is arranged on a transmission line tower, and a CORS reference station is established in a region which is not easy to subside or deform. The Beidou signal receiver 21 is arranged in the reference station 24, continuously observes satellites in the area, and transmits 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, processes the data in real time according to the relative positioning principle, gives out the three-dimensional coordinates of the observation station in real time, and the monitoring center 22 calculates the gradient in real time so as to realize real-time safety monitoring of the tower.
The specific process is shown in fig. 4, and for each power transmission line tower, the monitoring system of the power transmission line tower consists of a north bucket receiver and antenna, an ARM core board and a continuous operation stable reference station. A Beidou high-precision receiver is placed on the tower and used as a mobile station, and an antenna of the Beidou high-precision receiver is fixed on the top of the tower. The receiver is connected with the ARM core board through a serial port. The monitoring algorithm uses the Ntrip network protocol to communicate with the CORS station 23 to receive the differential data and write the data to the receiver for differential resolution by the receiver to obtain high accuracy positioning information. And simultaneously, the positioning information output by the receiver is read, and after the positioning information is processed and the inclination angle is resolved, the result is sent to an upper 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 over the Internet, initiated and formulated by the german federal mapping agency (BKT) at 2004. The Ntrip protocol consists of four parts, an Ntrip data source (Ntrip sources), an Ntrip client (Ntrip clients), an Ntrip server (Ntrip Server) and an Ntrip processing center (Ntrip). The software implementation method of the Ntrip client is as follows: the ARM module is used for realizing the function of the Ntrip client, sending an AT instruction, establishing socket connection with the CORS station 23 with the appointed IP address and port number, after establishing connection with the CORS station 23, sending request information to the CORS station 23 according to the format of the request information, obtaining differential data when the request passes, and sending the differential data to the receiver after the ARM module reads the differential data, so that the receiver can perform RTK high-precision positioning. In order to ensure that the receiver can always operate in the RTK mode, high accuracy positioning information is output, the requirement being that differential information can be obtained from the CORS station 23 continuously. Therefore, it is necessary to monitor in real time whether there is differential data all the time, and if the differential data is lost, it is necessary to reestablish a connection with the CORS station 23.
Regarding the acquisition of differential data in the application, the accuracy of monitoring the inclination angle of the tower can be improved from two aspects, namely, on one hand, the positioning accuracy of the Beidou receiver is improved; on the other hand, the accuracy of the tilt angle calculation algorithm is improved. When the Beidou receiver works in the RTK mode, the positioning accuracy is highest, and the centimeter level can be achieved. The RTK mode is that the receiver receives the observation information transmitted from the reference station 24 and the position information of the reference station 24, which are collectively called differential information, and then the receiver performs differential positioning, i.e., relative positioning, in combination with its own observation data, thereby greatly improving positioning accuracy. The currently common RTK method is a network RTK, with a continuously running reference station instead of the reference station 24.
Referring to fig. 8, fig. 8 is a schematic diagram of the frequency monitoring circuit in fig. 1. The frequency monitoring circuit in the application specifically comprises a 4046 chip and a 4518 chip, and is displayed in real time through an oscilloscope. It should be noted that, regarding the specific structure and the working principle of the signal sensor receiver, the a/D conversion circuit 11, the liquid crystal control circuit 12, the single chip microcomputer control circuit 13 and the frequency monitoring circuit, please refer to the prior art.
