Mining 5G base station radio frequency energy loss optimization method and device

Abstract

The invention relates to a mining 5G base station radio frequency energy loss optimization method and device. The optimization method comprises the following steps: selecting a coaxial cable model, and obtaining an attenuation coefficient and a diameter ratio parameter; determining the geometrical relationship between the length and the bending angle of the coaxial cable after the coaxial cable is installed and bent according to the roadway condition; and determining the bending angle and length when the attenuation is weakest based on the relationship between the mismatch coefficient and the angle, wherein the geometric relationship between the mounting of the mining 5G communication antenna and the base station in the roadway and the coaxial cable for realizing the connection is an isosceles triangle. The length of two equal sides of the isosceles triangle is half of the length of the coaxial cable, and the vertex angle of the isosceles triangle is the bending angle of the coaxial cable. Therefore, the emission efficiency of the radio frequency energy of the 5G base station can be improved, the coverage distance of the 5G base station can be improved, the layout number of the 5G base station can be reduced, and the construction cost can be reduced.

AI Technical Summary

Problems solved by technology

However, transmission line transformers usually have fixed models and parameters, and respond slowly to the situation where the characteristic impedance fluctuates with the change of the bending degree of the coaxial cable, and the transmission transformer is mostly designed for the situation where the characteristic impedance of the coaxial cable and the load are very different. , the function is relatively limited in reducing the impedance mismatch problem caused by the extrusion or bending of the feeder

The magnetic core of the transmission transformer also has an optimal working frequency band. When the frequency of the transmission signal changes, the transmission transformer needs to be replaced according to the actual transmission situation. Otherwise, the core loss may be caused, resulting in a decrease in transmission efficiency.
