3. The ground wire capable of being tracked and positioned saves cost and is more humanized.
Detailed Description
The present invention will be further described below, and it should be noted that the following examples are provided to illustrate the detailed embodiments and specific procedures based on the technical solution, but the scope of the present invention is not limited to the examples.
The invention relates to a system of a power transmission line grounding wire capable of being tracked and positioned, which is provided with a grounding wire and is characterized by comprising the following components:
the positioning machine is arranged in the grounding wire and used for receiving satellite signals and accurately positioning;
the wireless mobile terminal is in wireless communication connection with the positioning machine and is used for receiving and displaying the positioning information of the positioning machine;
the positioning machine comprises an MCU module, a GPS module and a GPRS module, wherein the GPS module and the GPRS module are electrically connected with the MCU module respectively.
It should be noted that the positioning machine further includes a GPS and beidou dual-mode positioning module.
It should be noted that the power supply used by the positioning machine supplies power to the lithium battery.
The ground wire and the positioning machine are respectively provided with the same code, and the codes are recorded in the wireless mobile terminal.
It should be noted that the basic principle of the satellite positioning system is to measure the distance between a satellite with a known position and a user receiver, and then integrate the data of multiple satellites to know the specific position of the receiver. To achieve this, the position of the satellite can be found in the satellite ephemeris from the time recorded by the on-board clock. The distance between user and satellite is obtained by recording the time that the satellite signal is propagated to user and multiplying it by light speed (because of the interference of atmosphere ionosphere, this distance is not the true distance between user and satellite, but Pseudo Range (PR). when the GPS satellite is normally worked, it can continuously use pseudo-random code (pseudo code) formed from 1 and 0 binary code group to transmit navigation message, the pseudo-code used for satellite positioning is two kinds, respectively, civil C/A code and military P (Y) code, C/A code frequency is 1.023MHz, its repetition period is one millisecond, code distance is 1 microsecond, is equal to 300m, P code frequency is 10.23MHz, repetition period is 266.4 days, code distance is 0.1 microsecond, is equal to 30m, and Y code is formed on the basis of P code, its security performance is better Clock correction, ionospheric delay correction, atmospheric refraction correction, and the like. It is demodulated from the satellite signal and transmitted on a carrier frequency with 50b/s modulation. Each main frame of the navigation message comprises 5 sub-frames with the length of 6 s. 10 character codes in each of the first three frames; repeated every thirty seconds and updated every hour. The two last frames are 15000b in total. The navigation message mainly comprises telemetry codes, conversion codes and data blocks 1, 2 and 3, wherein the most important is ephemeris data. When a user receives a navigation message, the distance between the satellite and the user can be known by extracting the satellite time and comparing the satellite time with the clock of the user, the position of the satellite when the message is transmitted is calculated by using the satellite ephemeris data in the navigation message, and the information such as the position speed of the user in a terrestrial coordinate system can be known.
The communication of the invention adopts a serial interface (UART), the module comprises 2 configurable serial ports (UART), the default baud rate is 9600bps, the 2 serial port baud rates can be configured by users, and the highest baud rate can be 115200 bps. The input/output signal type is TL level. The UM20-I supports the output data of the NMEA-0183 protocol standard to adopt ASCI codes, the content of the ASCI codes comprises longitude and latitude, height, speed, date, time, heading, satellite state and other information, and only time, date and longitude coordinates are concerned in the scheme.
Furthermore, the system of the invention realizes data networking through GPRS, and the MCU uploads the positioning information to the server through the serial port and the GPRS after acquiring the Beidou/GPS positioning information. The GPRS module has three working modes, namely a network transparent transmission mode, an HTPD mode and a short message transparent transmission mode, and the network transparent transmission mode is selected for uploading data. In this mode, the ground wire positioning information can send data to a designated server on the network through the GPRS module. The module can also receive data from the server and forward the information to the serial port.
Various corresponding changes and modifications can be made by those skilled in the art based on the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
