Two-way voice communication device, communication system and communication method

Abstract

The invention discloses a two-way voice communication device, communication system and communication method. The two-way voice communication device comprises a control module, and a Bluetooth module, a voice collection module and a voice playing module which are connected with the control module. The control module alternatively and synchronously sends an enabling instruction and an interruption instruction to the voice collection module and the voice playing module, thereby controlling the voice collection module and the voice playing module to be alternatively in a working state and an unworking state, and moreover, the control module externally sends a switching instruction through the Bluetooth module. Under the condition that a data transmission rate of the low-power-consumption Bluetooth module is relatively low, data transmission is carried out on large data volume in a half-duplex mode, and the problem that exiting full-duplex voice communication is high in power consumption or low in transmission quality is solved. The control module controls the voice collection module and the voice playing module to be alternately in the working state and the unworking state, thereby realizing intelligent switching of a voice call, and the problem that the intelligence of the existing half-duplex voice communication is insufficient is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a two-way voice communication device, a communication system and a communication method. Background technique [0002] At present, the two-way wireless voice communication technology mainly adopts the traditional Bluetooth communication technology, which performs voice communication in a full-duplex working mode. The price of traditional Bluetooth chips is relatively expensive, and the standby power consumption is relatively high, which has certain limitations in its application. It is mainly used in Bluetooth headset related equipment, and cannot be promoted in smart home and other fields. The wireless voice communication technology using Bluetooth Low Energy (BLE) technology is widely used in the field of smart wear due to its low cost and short distance advantages, but the transmission rate of data transmission using BLE technology is low and cannot be realized. For dat...
