Embodiment 1

[0059] Such as figure 2 As shown, the micropower wireless communication low power consumption control method in the embodiment of the present invention includes the following steps:

[0060] Step S201: The central controller broadcasts the data code: the central controller maintains a local time counter, and at the same time broadcasts a section of data code at a fixed time interval T, the data code includes the local time of the central controller, the transmission power of the central controller, the synchronization word, Broadcast time interval T, communication status bit, check code and other information; the central controller enters the receiving state after the broadcast is completed, and monitors the response of the terminal equipment.

[0061] Such as image 3 As shown, on the time axis of the central controller, every time slot T, the central controller broadcasts and sends a data code.

[0062] Step S202: the micro-power wireless terminal receives the data code b...

Embodiment 2

[0072] Such as Figure 4 As shown, it is another implementation mode of the low-power control method for micro-power wireless communication of the present invention, which includes the following steps:

[0073] Step S401: After reaching the communication connection time interval set in step S205 in the first embodiment, the micro-power wireless module wakes up from the shutdown state and enters the receiving state;

[0074] Step S402: When receiving the data code broadcast by the central controller, maintain and update the local time of the terminal, update the broadcast time interval T, adjust the terminal transmission power and other operations; process this communication process, and set the next time to wake up from the shutdown state The time interval is nT-t t -t p , the terminal sets the micro-power wireless module to the shutdown state again.

[0075] Among them, t t is the preset time margin value, t p In this communication process, the time from when the termina...

Embodiment 3

[0081] Such as Figure 5 and Figure 6 As shown, it is another implementation of the micropower wireless communication low power consumption control method of the present invention, including the following steps:

[0082] Step S501: When the central controller needs to send data, set the communication state position in the data code to 1, that is, there is a data sending state;

[0083] Step S502: When the terminal receives the data code, it performs state discrimination. If the communication state bit is 1, it sends a ready notification frame to the central controller, and then enters the receiving state;

[0084] Step S503: the central controller sends the data frame, and the terminal receives the data frame;

[0085] Step S504: The terminal replies with a receiving confirmation frame until the communication ends and the central controller sends an end frame.

Abstract

The invention discloses a low consumption control method for micro power wireless communication, a terminal and a system. The method comprises the following steps: receiving a data code broadcasted by a central controller, wherein the data code comprises a local time of the central controller, transmitting power of the central controller, a synchronization word, a broadcast time interval T, a communication state bit and a check code; updating the local time of terminal according to the local time of the central controller, and adjusting the transmitting power of the terminal according to the transmitting power of the central controller; and setting a time interval of waking from a shutdown state to establishing a communication connection with the central controller of a micro power wireless module as nT-tt-tp, and setting the micro power wireless module as the shutdown state, wherein tt refers to a preset time margin value, and tp refers to a time from sending a response message to the central controller to receiving a confirmation response message replied by the central controller.

Description

technical field [0001] The present invention relates to the technical field of micro-power wireless communication, in particular to a method, terminal and system for controlling low power consumption of micro-power wireless communication. Background technique [0002] Micropower wireless technology has been widely used in the Internet of Things, short-distance communication and other fields. However, under the premise of satisfying the communication function, its power consumption saving has always been a difficult problem to solve. It is of great significance to reduce power consumption from the perspective of micro-power wireless communication control itself. [0003] For some simple new application networks such as security, smart home, smart meters and medical equipment, the wireless communication function requirements are limited to the transmission of limited data to the central controller, and high requirements are placed on the service life of the battery. For such ...
