Experiment system platform for wireless sensor network

The invention discloses an experiment system platform for a wireless sensor network. The experiment system platform comprises a plurality of network nodes, a sink node Sink and an upper computer, wherein the network nodes are connected in sequence through an SPI (Serial Peripheral Interface) serial port and a wireless chip; the network nodes are connected with the sink node Sink through the SPI serial port and the wireless chip; the sink node Sink is connected with the upper computer through a serial port communication module RS232; the network nodes are used for acquiring and monitoring data information; the data information acquired by the network nodes is transmitted to the sink node Sink through the SPI serial port and the wireless chip; the sink node Sink transmits the data information to the upper computer through the serial port communication module RS232; and the upper computer processes and analyzes the data information on a monitoring interface to test the timeliness and fairness of the wireless sen
