Digital cluster talkback Bluetooth peripheral based on intelligent mobile terminal

Abstract

The invention belongs to the field of wireless communication, and particularly relates to a digital cluster talkback Bluetooth peripheral based on an intelligent mobile terminal. The digital cluster talkback Bluetooth peripheral comprises a Bluetooth module, a voice interface module, a controller and a power source management module. The Bluetooth module, the voice interface module and the power source management module are respectively connected to the controller. The Bluetooth peripheral is connected with the intelligent mobile terminal through the Bluetooth module, and can effectively control input and output of electric quantity through the power source management module, so that the Bluetooth peripheral stably works for a long time, voice volume can be increased, and a user can accurately obtain voice messages in complex environment.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a digital trunking intercom bluetooth peripheral based on an intelligent mobile terminal. Background technique [0002] In recent years, with the continuous innovation of communication industry technology, mobile phones with intercom functions have gradually attracted the attention of the public. One machine with two uses is not only economical but also convenient, entertainment and practical; The main way of communication, with the development of public mobile communication, the walkie-talkie market has gradually become an important professional communication market. The mobile phone intercom uses digital communication technology, which can effectively avoid the interference of traditional walkie-talkie analog signals, frequency crowding and unclear voice. Therefore, mobile phone intercom is widely used in various fields of the national economy and has become a ...

Problems solved by technology

[0003] However, the mobile phone walkie-talkie generally has a relatively large screen and a relatively high-level screen. When using a digital trunking intercom directly on a smartphone, it is necessary to keep the screen turned on. The long-term bright screen will shorten the standby time of the mobile phone sharply; the smart machine will start many programs. , just like a computer, the more open items on the mobile phone, the slower the speed and the more power consumption. At the same time, using the digital trunking intercom needs to connect to the wireless network, and connecting to GPRS requires a lot of power to start, and when the mobile phone is in the communication state, it needs to be connected to the wireless network. The high transmission power directly leads to a sharp increase in power consumption. Secondly, the smartphone is set by the mobile phone system, and the maximum volume is fixed. Due to its own hardware problems, the volume is generally low, and it is more complex in noisy crowds. When the intercom is used in the environment, it will lead to missed hearing
