Embodiment Construction
[0033] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.
[0034] Such as figure 1 Shown, technical scheme of the present invention comprises following 3 steps:
[0035] 1. Build a digital-energy-integrated wireless sensor network
[0036]11. On the basis of the traditional wireless sensor network, introduce wireless digital energy simultaneous transmission technology to form a wireless sensor network with integrated transmission of digital energy, and use the active characteristics of wireless access points to realize wireless digital energy simultaneous transmission in downlink transmission. Therefore, power supply is realized while sending beacon frames or other command frames to passive terminal sensor nodes.
[0037] Change the superframe structure and sequence of the traditional IEEE 802.15.4 pro...
