Description

Technical Field

[0001] The present invention relates to an antenna control structure, and in particular to an electric adjustment control system and an electric adjustment method for a base station antenna. Background Art

[0002] With the rapid development of mobile communication technology, antenna technology is also constantly improving. At present, electrically adjustable antennas have been widely used in the field of communications. Electrically adjustable antennas are a type of radio frequency transmitting and receiving device that corresponds to mechanical antennas. The antenna downtilt angle can be adjusted by electronic control. Compared with mechanical antennas, electrically adjustable antennas have the characteristics of simple adjustment and high adjustment accuracy. Since maintenance personnel do not need to perform mechanical operations directly, the antenna downtilt angle can be adjusted even when the antenna is in working condition.

[0003] Usually, the electrically tilted antenna is connected to the RCU (remote control unit), the RCU is connected to the RRU (radio remote unit) through an AISG (antenna interface standardization organization) cable, and the RRU is connected to the maintenance terminal located in the machine room through the BBU (baseband unit). The RCU sends the status information of the electrically tilted antenna to the maintenance terminal through the RRU and BBU, and the maintenance terminal sends a control instruction to the RCU according to the status information of the electrically tilted antenna, and the RCU adjusts the electrically tilted antenna according to the control instruction. The RCU, RRU, BBU and maintenance terminal communicate with each other through the AISG protocol. In actual application, a single maintenance terminal connects and controls a large number of antennas. The data of sending electrically tilted signals and receiving antenna status signals returned from the antennas need to be converted using AISG, which makes it easy to make mistakes when the processing volume of AISG is busy, and the equipment from the actual antenna to the maintenance terminal may not be produced by one company, which makes it easy to make mistakes when matching AISG. Summary of the invention

[0004] The present invention aims to solve the above-mentioned defects and provides an electrical adjustment control system and an electrical adjustment method for a base station antenna.

[0005] In order to overcome the problem that the existing transmission of electric adjustment data relying on AISG in the background technology is affected to a certain extent by busy processing and compatible matching of multiple devices, resulting in efficiency being affected and a high error rate in actual use, the technical solution adopted by the present invention to solve its technical problem is: an electric adjustment control system for a base station antenna, comprising an electric adjustment antenna and an RCU connected to the electric adjustment antenna, and a maintenance terminal connected to the RCU and arranged in a machine room, the RCU is provided with AISG, the AISG is connected to the RRU in the RCU, the RRU is connected to the BBU in the maintenance terminal, the maintenance terminal is provided with a communication module, the communication module is connected to the communication sub-module in the RCU, the communication sub-module is respectively connected to a signal receiving unit and a signal sending module in the RCU, and the signal receiving unit and the signal sending module are also respectively connected to the AISG.

[0006] Wherein, the maintenance terminal is also connected with a display and a network unit.

[0007] Among them, the signal receiving unit is composed of a first receiving unit, a first processing unit, a first filtering unit, a first amplifying unit, a first conversion unit and a first transmission unit which are connected in sequence. The first receiving unit is connected to the communication submodule, and the first transmission unit is connected to the AISG; the first receiving unit is used to receive the electric control signal sent from the communication submodule, the first processing unit is used to perform preliminary processing on the electric control signal, the first filtering unit removes clutter interference in the electric control signal to obtain clear signal data, the first amplifying unit amplifies the filtered electric control signal, and converts the electric signal into a digital signal through the first conversion unit, which is then transmitted to the AISG by the first transmission unit for identification and reading.

[0008] Among them, the signal sending module is composed of a second receiving unit, a second conversion unit, a second amplifying unit and a second transmission unit connected in sequence. The second receiving unit is connected to the AISG, and the second transmission unit is connected to the communication sub-module. The second receiving unit is used to receive the signal to be sent from the AISG. The signal is converted into an electrical signal by the second conversion unit, and then the signal is amplified by the second amplifying unit and transmitted to the communication sub-module by the second transmission unit for communication transmission.

[0009] The electrical adjustment method of the electrical adjustment control system for a base station antenna comprises the following steps:

[0010] Step 1: The maintenance terminal selects the BUU according to the antenna position that needs to be electrically adjusted, and then confirms the corresponding RCU and obtains the device identification number of the RCU;

[0011] Step 2: By identifying the confirmed device number, the electric adjustment control signal is sent to the corresponding RCU communication submodule for reception through the communication module;

[0012] Step 3: Process the received electrical adjustment control signal to obtain electrical adjustment parameter data, and perform corresponding antenna electrical adjustment according to the parameters;

[0013] Step 4: The adjusted antenna status information and operating parameter information are sent to the BBU of the maintenance terminal through the RRU in the AISG for reception, recording and display.

[0014] Wherein, in the step 4, while the antenna status information and the operating parameter information are sent by the RRU, the AISG simultaneously transmits the status information and the operating parameter information to the signal sending module for sending.

[0015] Wherein, the network unit is also connected to a mobile terminal with a remote control APP installed.

[0016] The beneficial effects of the present invention are:

[0017] 1. By setting up a communication module to match the transmission method from BBU to RRU, the large amount of AISG processing matching in a single path can be reduced, especially when the equipment from the antenna to the maintenance terminal is composed of multiple devices, the direct identification of the equipment and the communication of the protocol will affect the signal processing efficiency, while reducing the matching error rate.

[0018] 2. Use the traditional BBU to RRU path to identify the antenna device to be electrically adjusted. This method has the advantages of fast recognition speed and high accuracy. According to the identified device information, the communication module sends the electrical adjustment signal to the RCU. The signal can be sent quickly with high fidelity. The status information of the antenna after electrical adjustment is then transmitted from the BUU to the RRU. By using dual paths to transmit and send signals and data, the advantages of both are fully utilized to achieve better results.

[0019] 3. By equipping with a remote control APP, mobile devices such as mobile phones, tablets and laptops can install the APP and use the network to wirelessly connect to the maintenance terminal. When setting and controlling the ESC, personnel can set and control it anytime and anywhere, which improves the flexibility of use. BRIEF DESCRIPTION OF THE DRAWINGS
