Device, system and method for wireless modulation and test of tunable antenna

Abstract

The invention relates to a device, system and method for wireless modulation and test of a tunable antenna. The device comprises a WIFI module, a level conversion module, an AISG interface, and a power management module; the WIFI module is used for establishing wireless connection with a master control end and receiving a tunable antenna modulation and test instruction sent by the master control end, a UART interface is arranged on the WIFI module, and the UART interface is used for converting the tunable antenna modulation and test instruction received by the WIFI module into a TTL level signal to output; the level conversion module is connected with the UART module and used for converting the TTL level signal output by the UART interface into a RS485 level signal capable of being recognized by the AISG interface; the AISG interface is connected with the level conversion module and used for receiving the RS485 level signal output by the level conversion module and outputting the received RS485 level signal to a tunable antenna controller to realize the modulation and test on the tunable antenna; and the power management module is connected with each of the WIFI module, the level conversion module and the AISG interface. The wireless modulation and test on the tunable antenna can be realized, the weight on a tower worker can be greatly relieved, and the dangerousness and the physical requirement on the tower worker and the cost can be reduced.

Description

【Technical field】 [0001] The invention relates to the field of commissioning and testing of electric antennas, in particular to a device, system and method for wireless commissioning of electric antennas. 【Background technique】 [0002] With the rapid development of mobile communication technology, electric adjustable antennas have been widely used in the field of communication. Electric adjustable antennas can use electronic control to adjust the downtilt angle of the antenna, and the downtilt angle of the antenna can also be adjusted when the antenna is working. Modulation, the electronically adjustable antenna controller (RCU) is the controller that adjusts the downtilt angle. Like the electronically adjustable antenna, it is often installed on a higher iron tower, that is, it is installed in a place that is not easy for engineering maintenance personnel to reach. When the ESC antenna controller fails and requires on-site maintenance or program upgrades, it is necessary t...

AI Technical Summary

Problems solved by technology

When the ESC antenna controller fails and needs on-site maintenance or program upgrade, it is necessary to climb towers or communication poles. It is very inconvenient to debug the ESC antenna at these locations.

The existing practice is generally that professional tower workers carry AISG (Antenna Interface Standards Organization) debugging cables tens of meters long and weighing tens of kilograms to the tower or communication pole, and the engineering maintenance personnel hold the control unit (PCU) or The PC is commissioned on the ground, which greatly increases the load of the tower worker, which greatly increases the danger of the tower worker, and the cost of the tower worker also increases. At the same time, the physical requirements of the tower worker are also greatly increased, so that it is impossible to climb a few in a day. communication pole
