Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] Such as figure 1 As shown, a wireless sensor network node includes a processor, an FPGA chip and a radio frequency circuit. The central processing unit can select a low-power processor, and the same as the prior art, the central processing unit has a cache. The processor is electrically connected to the FPGA chip, and the radio frequency circuit is electrically connected to the FPGA chip. The address of the surrounding wireless network nodes is pre-stored in the central processing, and the processor can calculate and select which wireless sensor network node can reach the final destination through the surrounding area according to the final destination of the tran...

Abstract

A wireless sensor network transmission method belongs to the field of wireless sensor network technology. The method comprises that a radio frequency circuit receives address confirmation packets and transmits data; a central processing unit is used for selecting wireless sensor network nodes and controlling the sleep time of the wireless network sensors; an FPGA (field programmable gate array) chip compares target addresses inside the address confirmation packets with the addresses of the wireless sensor network nodes. Compared with the prior art, the wireless sensor network transmission method has the advantages that, through single-frequency-range operation, next-step addresses are selected from multiple wireless sensor network addresses preset in the central processing unit for direct data transmission, so that efficient data transmission can be achieved, and a function of reducing power consumption of the nodes can be obtained.
