AAU intelligent constant temperature system, device and method of 5G base station

Abstract

The invention discloses an AAU intelligent constant temperature system, device and method of a 5G base station. The device comprises a box body support, a plurality of blade type solar energy and windenergy comprehensive power generation units, a temperature control unit and a remote monitoring unit. The blade type solar energy and wind energy comprehensive power generation units are used for generating power, storing power, shading sun, cooling and forming a box body; the temperature control unit is used for detecting the temperature of the AAU cooling fin, converting the running state of the refrigerating and heating module group, detecting the running environment, collecting running information and data, and uploading the running information and data to the remote monitoring unit through the communication module; and the remote monitoring unit is used for dynamically storing and monitoring the operation information of the plurality of AAU intelligent constant temperature devices. Solar energy and wind energy power generation is achieved, and power supply is not needed; the judging device realizes intelligent sun shading, and automatically closes or opens the blade plates according to the direction and intensity of the sun; the existing structure of the AAU is not changed, modular design is adopted, module installation is achieved, and installation and maintenance are facilitated.

Description

technical field [0001] The invention belongs to the technical field of communication equipment, and in particular relates to an AAU intelligent constant temperature system, device and method for a 5G base station. Background technique [0002] AAU (Active Antenna Unit), is the main equipment of 5G base station. AAU is mainly composed of DAC (digital-to-analog conversion), RF (radio frequency unit), PA (power amplifier) ​​and antenna. It is mainly responsible for converting baseband digital signals into analog signals, then modulating them into high-frequency radio frequency signals, and then amplifying them to After sufficient power, it is emitted by the antenna. At present, the power consumption of the AAU composed of 64 T / R modules of the 5G wireless main equipment is 2-3 times that of the 4G 8-channel RRU, and the current cooling method of the AAU of the 5G base station is to use a cast aluminum thickened shell to dissipate heat through the external natural environment ...

AI Technical Summary

Problems solved by technology

At present, the power consumption of the AAU composed of 64 T / R modules of the 5G wireless main equipment is 2-3 times that of the 4G 8-channel RRU, and the current cooling method of the AAU of the 5G base station is to use a cast aluminum thickened shell to dissipate heat through the external natural environment , since the AAU is installed on an outdoor communication tower (pole), when installed in natural environments in different regions (such as the hot climate in the south and the cold climate in the northeast), the surface temperature of the shell can be as high as 60°C to 90°C or -30°C Below, exceeding the operating temperature range of AAU, especially the increase in temperature, will lead to the intensification of carrier movement in the T / R module, and more and faster carriers, whether it is an increase in current or a decrease in resistivity, will cause T The increase in power consumption of the / R module, that is, the increase in AAU power consumption
