Method and system for wirelessly and remotely controlling beacon equipment to generate radio frequency signal

Abstract

The invention relates to a method and a system for wirelessly and remotely controlling beacon equipment to generate a radio frequency signal. A Raspberry Pi small computer is adopted, the computer is connected with a radio station and a second beacon ball through a first data line, is connected with a first beacon ball through a second data line, and is connected with a signal source through a network cable; the computer edits and generates a control beacon device to modify dot frequency and output a signal instruction, the instruction is wirelessly sent to the calibration tower through the ground station radio station, the calibration tower radio station receives the instruction and transmits the instruction to the computer, and the computer automatically sends the instruction to the signal source, the first beacon ball and / or the second beacon ball after reading the instruction content. And the beacon device generates a required radio frequency signal after executing the instruction, and returns an execution state through the radio station. The tower calibration preparation time of a ground station is remarkably shortened, manpower and material resources are saved, the method has the advantages of being efficient and accurate in control, beacon signals of the signal source and the beacon ball are mutually backed up, and the method is more stable and reliable.

Description

technical field [0001] The present invention relates to the technical field of signal generation, and more particularly, the present invention relates to a method and system for generating radio frequency signals by wireless remote control beacon equipment. Background technique [0002] Calibration of the tower is an important way to calibrate the phase of the radar system and verify the status of the equipment. Under normal circumstances, during the implementation of the tower calibration, the post personnel are required to transport the signal source equipment to the calibration tower 5 kilometers away, go to the top of the tower to manually build the beacon generation environment, and communicate with the ground station by telephone or walkie-talkie. Source turn-on and frequency modification. During manual communication, personnel carry walkie-talkies and signal source equipment to board the calibration tower; when signal parameters need to be changed, ground station per...

Problems solved by technology

[0003] The whole process of tower calibration involves many links such as personnel and vehicles, construction environment, communication and coordination, etc. The organization and implementation is time-consuming and inefficient, and the process needs to be repeated every time tower calibration

For specific applications that require frequent tower calibration, for example, an average of more than 20 times a year, a lot of manpower and material resources are wasted

Moreover, the signal source is not suitable for continuous long-term power-on work as an expensive instrument
