[0033] refer to Figure 1-3

[0034] The communication node that is used for WSN and EPON networking, comprises ARM processor, power supply module, RJ45 interface, it is characterized in that: described communication node also comprises a wireless transceiver module connected with each node in WSN network and the POS with EPON network The photoelectric conversion module connected to the node; the wireless transceiver module has a wireless receiving unit that receives the data forwarded by each WSN node and converts the data into an electrical signal, and the wireless receiving unit can convert the output electrical signal into The optical signal is connected to the photoelectric conversion module that transmits the optical signal to the POS; the wireless receiving unit and the photoelectric conversion module are controlled by the ARM processor.

[0035] The wireless transceiver module also includes a wireless sending unit that can receive instructions from a management node con...

Embodiment 2

[0051] refer to Figure 3-5

[0052] The WSN and EPON network using the WSN-OUN node, the WSN has a large number of WSN nodes deployed in the observation area, and the WSN nodes are connected to each other in the form of self-organization; the EPON includes The POS node that receives the optical signal and the OLT that transmits the optical signal from the POS to the Ethernet, the OLT sends data to the Ethernet through the GE interface; the WSN node is connected to the POS through the WSN-OUN node, and the The WSN node is connected to the wireless receiving unit of the WSN-OUN node, and the POS is connected to the photoelectric conversion module of the WSN-OUN node through an optical fiber interface.

[0053] The WSN and EPON networking also has a management node connected to Ethernet and capable of network configuration for all WSN nodes, and the network management module of the management node is connected with the wireless sending unit of the WSN-OUN node.

Embodiment 3

[0061] Combine the application of the present invention in agricultural environment monitoring and Image 6 ,Further explanation:

[0062] Image 6The application of WSN-EPON in agricultural environment monitoring is shown. Temperature, humidity and soil pH play a very important role in the growth of plants, but it is unrealistic to use specialized soil analysts to measure and chemically analyze the soil, which is time-consuming and laborious. The WSN nodes with sensor functions distributed on the edge of the farmland are used to measure the moisture content in the soil, soil Ph value and air temperature and other environmental indicators and send these data to the WSN-ONU wirelessly. Then these data enter the Ethernet through the central office equipment OLT in EPON; the management node at the other end of the Ethernet will receive these information and send control commands to activate or disable certain WSN nodes. In this way, the manager can know the current environment...
