Embodiment 1

[0036] Such as figure 1 and 2 As shown, the energy-saving wake-up method applicable to a half-duplex wireless communication system provided in this embodiment, that is, on the side of a half-duplex base station (which can be but not limited to a half-duplex reader or a half-duplex reader-writer) can be But not limited to include the following steps S101-S102.

[0037] S101. The half-duplex base station first enters the wireless transmission working mode: continuously and periodically sends multiple terminal wake-up messages on the working channel within the first period of time, wherein the terminal wake-up messages include target address information, the first period of time Duration information and current message sending clock information, the target address information is used to indicate the half-duplex wireless terminal to be awakened, the first period duration information is used to indicate the duration t of the first period, the current message The sending clock inf...

Embodiment 2

[0053] Such as image 3 As shown, this embodiment provides a half-duplex wireless communication system that implements the energy-saving wake-up method described in Embodiment 1 above, including a half-duplex base station, wherein the half-duplex base station includes a first wireless transmitting unit, a second a wireless receiving unit and a first switching unit;

[0054] The first wireless transmitting unit is configured to continuously and periodically transmit multiple terminal wake-up messages on the working channel within the first period of time;

[0055] The second wireless receiving unit is configured to listen to a working channel after sending the last terminal wake-up message, and receive a data upload message from a half-duplex wireless terminal, wherein the terminal wake-up message includes a target Address information, first period duration information and current message sending clock information, the target address information is used to indicate the half-du...

Abstract

The invention relates to the technical field of wireless communication technology or Internet of Things radio frequency identification, and discloses an energy-saving awakening method suitable for a half-duplex wireless communication system. he invention provides an energy-saving awakening method capable of avoiding unnecessary energy consumption on a half-duplex wireless terminal / active tag side.Reservation time information is configured in a terminal wake-up message; after the half-duplex wireless terminal / active tag obtains the terminal awakening message, the sending end time of the roundcan be known, so that a long temporary dormancy time can be set for dormancy, a feedback data uploading message is awakened after the sending end, and therefore, the energy conservation of the wireless terminal can be facilitated, and the endurance time can be prolonged. In addition, the energy-saving awakening method further has the advantages of being free of awakening omission, safe in data uploading, flexible in application and the like, and practical application and popularization are facilitated.

Description

technical field [0001] The invention belongs to the field of wireless communication technology or the radio frequency identification technology of the Internet of Things, and in particular relates to an energy-saving wake-up method suitable for a half-duplex wireless communication system. Background technique [0002] Radio frequency identification, RFID (Radio Frequency Identification) technology, also known as radio frequency identification, is a wireless communication technology, commonly known as electronic tags, which can identify specific targets and read and write related data through radio signals. Among them, electronic tags with independent power supply Also known as active tags, otherwise known as passive tags. At present, RFID technology has been widely used in various fields, such as goods sales, transportation, production, waste management, postal tracking, air baggage management, vehicle toll management and other fields. Traditional paper barcodes cannot be re...
