Description

Technical Field

[0001] The utility model belongs to the field of signal receiving equipment of pRRU, in particular to a signal receiving device of a high-power pRRU. Background Art

[0002] pRRU, also known as pico base station, is a miniaturized, low-power, low-consumption micro-cellular base station, mainly designed to solve indoor wireless coverage problems in specific areas. pRRU usually consists of a host and an external antenna. The host is usually installed indoors to process and convert signals, and the external antenna is installed outdoors to receive and transmit signals. The external antenna plays a key role in the transmission channel. After receiving the digital signal from the DCU, the transmission channel first performs digital-to-analog conversion, and then uses zero intermediate frequency technology to modulate the digital signal to the transmit frequency band. After filtering and amplification, the external antenna in the transmission channel transmits the processed RF signal, thereby realizing wireless transmission of the signal, allowing the data to propagate in space to the target receiving end. In the receiving channel, the external antenna receives the RF signal from the outside world, then filters and amplifies it, uses zero intermediate frequency technology to down-convert the RF signal, converts the RF signal to a digital signal, and sends it to the DCU for processing after analog-to-digital conversion. This process is an important link in receiving external information, allowing the device to obtain various data, instructions and other information from the outside.

[0003] According to Chinese patent application number: 202321727611.7, a conveniently adjustable WeChat signal receiving device is disclosed, including a mounting assembly and a positioning assembly, wherein a main body is provided above the mounting assembly, the main body is fixedly connected to the top of the mounting assembly, a mounting column is provided between the mounting assembly and the positioning assembly, and bolts are evenly distributed on both sides of the positioning assembly, the bolts pass through and are fixedly connected to the positioning assembly, and the end of the bolt away from the positioning assembly passes through and is movably connected to one side of the mounting assembly, and the positioning assembly is provided with evenly distributed leather pads near the inner wall of the mounting column, and the leather pads are fixedly connected to the positioning assembly; finally, when it is necessary to make the signal receiving device receive signals better, the height of the signal receiving device can be conveniently adjusted;

[0004] The existing technology effectively solves the problem that the existing receiving device basically has high-width signal reception and needs to be installed on a mounting pole on a rooftop or roof. However, since the signal is better at a high place, its height needs to be adjusted after installation. At this time, it needs to be manually disassembled and reinstalled to adjust the height, thereby limiting work efficiency. It has the advantage of being able to easily adjust the height of the signal receiving device, but the signal receiving device needs to be adjusted at the installation angle during installation, and this type of signal receiving device is not convenient to adjust the angle during installation, which brings inconvenience to the installation.
