Abstract

The invention provides a low-power-consumption dormant device awakening method and system. The method comprises: S1, a sending device circularly sending an awakening code comprising a short lead codeand a receiving address according to a preset sending period; S2, the receiving device automatically awakening according to a preset awakening period and opening a corresponding wireless receiving module within a preset awakening duration, and detecting whether the awakening code exists in the air or not; S3, if the receiving device detects that the wake-up code exists in the air, analyzing whether a receiving address in the wake-up code is consistent with an address of the receiving device or not; S4, if the receiving address is consistent with the address of the receiving device, receiving asubsequent data packet, and entering a low-power-consumption dormant state after the data packet is received; otherwise, directly entering a low-power-consumption dormant state. The power consumptionin the awakening process of the low-power-consumption dormant device is reduced.

Description

technical field [0001] The present application relates to the technical field of data communication, and in particular, to a method and system for waking up a low-power sleep device. Background technique [0002] In the application of the Internet of Things, the low power consumption performance of the system is a very important indicator. In the wireless communication system, if the receiver wants to receive wireless data normally, the device must be in a receiving state with high energy consumption. In order to solve this problem, the Wake On Radio (WOR) technology has been produced. The principle of this technology is to control the receiver to switch continuously between receiving and sleeping states. This method can reduce the average power consumption of the system. In the "receiving + dormancy" system, if the transmitter sends data during the dormancy period of the receiver, obviously the data packet cannot be sent successfully, so the sender needs to use the above-me...
