Electrically-controlled antenna control device with pluggable function

Abstract

The invention discloses an electrically-controlled antenna control device with a pluggable function and belongs to the electrically-controlled antenna technical field. The device comprises an electrically-controlled antenna controller, a lower end cover, a reflecting plate and a transmission execution component; the electrically-controlled antenna controller is the power part of the whole device and comprises a stepping gear motor, a control panel and a lightning protection panel; control signals are transmitted to the control panel through an RS485; the control panel controls the motor to rotate; the motor drives a screw rod to rotate; the screw rod drives a sliding block to move linearly; and therefore, a phase shifter can be made to act to adjust phase. The electrically-controlled antenna control device has the advantages of pluggable function, simple structure and convenient operation. Compared with a built-in electrically-controlled antenna controller, the electrically-controlled antenna control device is advantageous in high reliability and convenient replacement. Compared with an externally-arranged electrically-controlled antenna controller, the electrically-controlled antenna control device can assist in full utilization of the internal space of an antenna and saving the installation space of an end surface, and therefore, much space can be left for an antenna feeder. The electrically-controlled antenna control device can be integrated in an electrically-controlled antenna unit, and therefore, errors in on-site installation and parameter configuration can be avoided, and overall reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of electric antenna control, in particular to an electric antenna control device with a pluggable function. Background technique [0002] The so-called electronically adjustable antenna is a mobile antenna that electronically adjusts the downtilt angle. [0003] With the strengthening and optimization of my country's mobile communication infrastructure network construction, the automatic electrical adjustment antenna is more and more used in the mobile communication field, and the controller preset at its lower end can be conveniently adjusted in real time according to the actual traffic demand. Angle for better signal coverage. The advantages of electronically adjustable antennas have led to the large-scale application of many domestic mobile networks, and the management of electronically adjustable antennas has gradually developed to remote networking control. As the most critical intelligent accessory ...

AI Technical Summary

Problems solved by technology

The external RCU and the electric adjustable antenna are independent of each other. It is necessary to install the electric adjustable antenna on the tower on site, and install it on the lower end cover of the antenna. Since the antenna controller occupies a large area and the area of ​​the end cover is limited, there are many antennas. Port feeder layout is difficult

At the same time, during installation, it is necessary to manually record the antenna type connected to the RCU, and configure the corresponding ESC antenna parameters on site or at the networking end, which will easily lead to frequent installation errors, thereby increasing the cost of on-site installation and maintenance. It is difficult for mobile network operators and antenna manufacturers to control the generation of errors

In another way, the built-in RCU, as the name suggests, is fixed inside the antenna, and the built-in RCU is an active device. Compared with the passive antenna, the reliability is obviously very low. Therefore, it can be seen that the built-in RCU has unavoidable disadvantages of inconvenient maintenance. , if there is a problem with the built-in RCU, it cannot be repaired or replaced, and the ESC antenna can only be replaced, which shortens the market life of the ESC antenna
