Abstract

The invention discloses a two-way voice transmission system comprising a node A and a node B, wherein each of the node A and the node B comprises a voice collection module, a voice output module and a core processing module, the voice collection module comprises a microphone and an AD converter, the voice output module comprises a loudspeaker and a DA converter, and the core processing module comprises a wireless transmitting circuit and a wireless receiving circuit. During voice transmission, the microphone of the node A receives a voice signal and transmits the signal to the core processing module after processing the signal through the AD converter, and the wireless transmitting circuit of the core processing module of the node A transmits the signal after AD conversion to the node B; the wireless receiving circuit of the core processing module of the node B receives a wireless signal and outputs the wireless signal to the voice output module of the node B, and the wireless signal is transmitted by the DA converter to the loudspeaker to output voice; and the node B sends the voice to the node A in the same principle so as to accomplish two-way voice transmission. The two-way voice transmission system disclosed by the invention requires no license, and has the advantages of low cost, good safety and good data fluency.

Description

technical field [0001] The invention relates to the field of electronic voice transmission, in particular to a two-way voice transmission system. Background technique [0002] Modern science and technology are increasingly developing towards high-speed, intelligent, informatization, and networking, making various manufacturing and communication equipment not only connected to computers, but also connected to each other, so as to realize the ultimate mutual connection between devices. The most promising way is wireless communication. Compared with wired communication, wireless communication has a series of advantages, especially suitable for handheld field equipment, battery-powered equipment, remote control telemetry equipment, hydrometeorological monitoring equipment, biological signal acquisition systems, industrial data acquisition systems, etc. The existing wireless data transmission products are roughly divided into the following categories: wireless voice transmission...
