Embodiment Construction

[0032] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] see figure 1 , the figure shows a method for reducing power consumption of a digital walkie-talkie according to an embodiment of the present invention, including steps:

[0034] Step S101: The digital walkie-talkie detects the channel signal strength according to the preset channel strength detection cycle;

[0035] Step S102: When the channel signal strength exceeds a threshold, enter a normal working state; otherwise, enter a sleep state.

[0036] Among them, when the digital walkie-talkie enters the sleep state, all circuits that can be closed are turned off, so as to minimize the power consumption of the entire circuit.

[0037] Wherein, the threshold value is generally the effective call signal strength of the digital walkie-talkie, and the specific value can be set according to empirical values, which is not limited in the present invent...

Abstract

The invention provides a method and device for reducing the power consumption of a digital interphone. The method comprises the following steps of: periodically detecting channel signal strength by utilizing the digital interphone according to the preset channel strength, when the channel signal strength exceeds a threshold value, entering a normal working state, and otherwise, entering a sleep state. With the method, the stand-by power consumption of the digital interphone can be reduced, and the service time of the interphone can be prolonged under the same battery capacity.

Description

technical field [0001] The invention relates to a digital walkie-talkie, in particular to a method and device for reducing power consumption of a digital walkie-talkie. Background technique [0002] Because of its immediacy and free principle of communication, walkie-talkie is widely used in various fields. With the deepening of the analog-to-digital conversion process of walkie-talkies, digital walkie-talkies have been used more and more, and their call quality and channel utilization have been greatly improved. As a communication method in the special communication field, digital walkie-talkies have attracted the attention of many manufacturers, and a variety of communication modes have been proposed, including DPMR, DMR, iDEN, TETRA and other standards. As the world's largest supplier of walkie-talkies, my country has continuously increased investment in the field of digital walkie-talkies and has made great progress. [0003] Unlike public communication networks such a...
