Embodiment Construction
[0031] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0032] see figure 1 , the present invention provides a three-in-one digital walkie-talkie, including a processor and a DMR module connected to the processor, a 4G LTE module, a satellite communication module, an audio codec, a microphone and a speaker;
[0033] The DMR module, on the one hand, receives DMR wireless signals sent by other walkie-talkies or DMR receivers within the specified range, converts them into DMR voice signals and sends them to the processor; on the other hand, receives the DMR voice signals sent by the process...

The invention discloses a three-in-one digital walkie-talkie, which relates to the technical field of walkie-talkies. Including a processor and a DMR module, a 4G LTE module, a satellite communication module, an audio codec, a microphone and a speaker connected to the processor; the DMR module receives DMR wireless signals within a specified range and converts them into DMR voice signals and send it to the processor; receive the DMR voice signal sent by the processor, convert it into a DMR wireless signal and transmit it to the specified range; the 4G LTE module is connected to the Internet network to realize the information interaction between the processor and the Internet; the The satellite communication module is connected to the Internet network through the satellite to realize the information interaction between the processor and the Internet; the audio codec is used to switch between the voice digital signal and the analog signal, and the audio codec is also connected with a microphone and a trumpet. The invention not only ensures the signal transmission distance of the walkie-talkie, but also solves the problem caused by the interruption of the network signal.
Description
technical field [0001] The invention relates to the technical field of walkie-talkies, in particular to a three-networks-in-one digital walkie-talkie. Background technique [0002] In major natural disasters, uninhabited areas, and forest emergency command communications, the current mature solutions are based on traditional DMR intercom or public network POC solutions, but both solutions have certain defects. For example, the DMR transmission distance is only Several kilometers, the public network POC depends on the operator's network signal and so on. The current walkie-talkie cannot solve the problems of transmission distance and network signal at the same time, which will limit the usage scenarios of the walkie-talkie. How to develop a walkie-talkie that can not only solve the signal transmission distance, but also solve the interruption of network signals is one of the problems to be solved urgently. Contents of the invention [0003] The purpose of the present inve...
