Embodiment Construction

[0059] Such as figure 1 As shown, in the flowchart of an embodiment of the wireless communication method of the present invention, the wireless communication method is used to send information to the slave device when the master device has a communication need, and the wireless communication method includes:

[0060] S1. The master device encodes the information code sequence containing the communication requirements into a wake-up sequence, and continuously sends the wake-up sequence to each slave device within a preset time, the wake-up sequence includes at least two parts, and the at least two Parts have a preset correlation, the preset time is greater than or equal to the sum of the sleep period and the detection period of the slave device, and the sum of the sleep period and the detection period constitutes a sleep wake-up cycle;

[0061] S2. The slave device receives the wake-up sequence during the detection period, decodes the wake-up sequence, and judges the correlatio...

Abstract

The invention discloses a wireless communication system and method. The wireless communication method comprises the steps: S1, a main device encodes an information code sequence including a communication request into an awakening sequence and continuously sends the awakening sequence to each slave device within a preset time period, wherein the awakening sequence comprises at least two portions, the at least two portions have preset relevancy, the preset time period is larger than or equal to the sum of a sleeping period and a detection period of the slave device, and the sum of the sleeping period and the detection period form a sleeping-awakening period; S2, the slave devices receive the awakening sequence in the detection period, decode the awakening sequence, judge the relevancy of the at least two portions, decide to perform awakening or not and perform corresponding response according to decoded information. By implementing the technical scheme, the power consumption of wireless communication is reduced, the encoding efficiency is improved, and the communication process is simple.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a wireless communication system and method. Background technique [0002] Micropower (short distance) wireless communication technology began to appear at the end of the last century. After more than ten years of development, it has been widely used in industrial control, home intelligence, wireless remote control, security alarm, environmental monitoring, smart meter reading, toxic and harmful gas monitoring, Logistics, RFID and other fields. In recent years, the Internet of Things has been regarded as a new growth point for future economic development after the financial crisis at home and abroad. The short-distance wireless communication technology will get greater development in the application of the Internet of Things (especially the sensor network). [0003] The concept of the Internet of Things came almost simultaneously with the low-carbon econom...
