Embodiment
[0038] Embodiment. This example (overall structure sees attached figure 1 ) The wireless sensor network constituted is a linear network, and now the whole network working process is explained.
[0039] The wireless sensor network node is based on the Texas Instruments chip radio frequency microcontroller CC1110, and adopts the time division multiplexing working mode. The whole system is mainly composed of solar power supply module, radio frequency transceiver CC1110, downlink (mainly including radio frequency front-end power amplifier, 3db bridge), uplink link (low noise amplifier, RF switch). The solar power supply module is connected to the RF microcontroller, the input of the RF microcontroller is connected to data acquisition, the output of the RF microcontroller is connected to the impedance transformation circuit, the output and input of the impedance transformation circuit are respectively connected to the input and output of the first RF switch, and the output of the ...
