Control device of multiple-antenna system

Abstract

The invention relates to a control device of a multi-antenna system and belongs to the communication technical field. The control device is electrically connected with an electronic communication device. The control device includes an multi-antenna system, an antenna control unit, a wireless module set and a micro processing unit; the antenna control unit is electrically connected with the multi-antenna system; the wireless module set is electrically connected with the antenna control unit; the micro processing unit is electrically connected with the antenna control unit and the wireless module set; signal intensity judgment logic is constructed in the micro processing unit; the multi-antenna system receives wireless radio frequency signals; the wireless radio frequency signals are transmitted to the wireless module set through the antenna control unit; the wireless module set transmits received signals to the micro processing unit; the micro processing unit judges whether the intensity of the received signals is lower or higher than a predetermined value through the signal intensity judgment logic; and after logic calculus processing is performed on the signals, signals are outputted to control the antenna control unit to change the radiation pattern of the multi-antenna system. The control device can simply integrate an existing wireless communication module set, so that the design of the multi-antenna system can be simpler and more convenient.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a control device for a multi-antenna system, which is used for controlling the change of antenna radiation directions. Background technique [0002] With the continuous development of science and technology, the communication equipment can be fully utilized to complete by wire or radio, and various communication methods such as fixed-line telecommunications, wireless telephone, mobile phone, Internet and even video telephone have appeared one after another. Therefore, communication technology shortens the distance between people, improves the efficiency of communication, and profoundly changes human communication. [0003] At present, the antennas used to receive wireless signals generally have the following three designs: [0004] A. Omnidirectionality: the advantage is that the sending and receiving signal angle is large, but the disadvantage is that the send...

Problems solved by technology

[0004] A. Omnidirectionality: the advantage is that the sending and receiving signal angle is large, but the disadvantage is that the sending and receiving signal distance is relatively short;

[0005] B. Directivity: The advantage is that the sending and receiving signal distance is long, but the disadvantage is that the sending and receiving signal angle is small;

[0006] C. Traditional multi-antenna control system: such as figure 1 , including a multi-antenna system 10 electrically connected to an antenna control unit 20, and the antenna control unit 20 electrically connected to a wireless module 30. The advantage of this system is that the distance is long and the angle is large. The disadvantage is that as long as the antenna design is changed, it will be changed. Overall control of wireless modules, high cost
