Abstract

The invention discloses a gateway device base on multi-antenna data information fusion. According to the device, a wireless signal gathering module is in charge of collecting information of a wireless sensor terminal, and fusing collected signals through a data conversion module; and wired Ethernet, CAN bus, or RS485 and other various communication modes are chosen to use according to the actual network deployment at a scene to send the collected data to a remote control terminal, wherein when data transmission is conducted between the wireless signal gathering module and a wireless sensor network node, a multipoint-multipoint communication is realized by selecting the multi-antenna technology and the frequency division multiplexing technology, so as to not only improve the scene information multiplexing efficiency, but also can allow the channel capacity to dynamically exchange channels according to working requirements of each module; the collected data are subjected to conversion and packaging of a data protocol by the data conversion module according to network transmission requirements, and packaged signals are transferred to a remote control terminal by the data conversion module, so as to improve the versatility of the gateway device in an industrial scene.
