Control device of multiple-antenna system

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.
