Novel wireless multiple input multiple output (MIMO) sensor node

The invention discloses a novel wireless multiple input multiple output (MIMO) sensor node, which comprises a plurality of data acquisition modules, a plurality of radio frequency transceiving modules, a data processing module, antennas connected with the radio frequency transceiving modules, and a power module, wherein the data processing module is used for analyzing and processing signals acquired by the plurality of data acquisition modules, transmitting the signals through the radio frequency transceiving modules and analyzing and processing the signals received by the radio frequency transceiving modules; the power module supplies power to the data processing module and the radio frequency transceiving modules; and the data processing module comprises a digital signal processor (DSP) controller and a field programmable gate array (FPGA) connected with the DSP controller. The sensor node has reasonable circuit design, convenient for wiring, flexible using modes and high data transmission rate and can be used for acquiring and transmitting massive data information or converging and forwarding data of a large-scale wireless sensor network, and the problem of restriction on network size and node data acquisition capacity in a Zigbee network node due to a lower transmission rate can be effectively solved.
