The invention discloses a novel individual inter-conversation
system comprising inter-conversation equipment and multiple different pieces of function sub-equipment, wherein the inter-conversation equipment comprises a shell, a
radio frequency transceiving unit, a modulation and
demodulation unit, a
microphone, a
loudspeaker, a human-computer interface unit, keys, an antenna, a first
wireless communication module and an MCU
control unit arranged on the shell; each function sub-equipment is provided with a second
wireless communication module that is in a
signal connection with the first
wireless transmission module; and all the inter-conversation equipment and the function sub-equipment are provided with matched antenna interfaces. The function sub-equipment is also simple to update and extend, the function sub-equipment with the new function can be directly used for replacing the function sub-equipment with the old function, or the function sub-equipment can be randomly added, and thefunction sub-equipment is short in development cycle, so that the timely
upgrade of the inter-conversation
system is facilitated, the whole inter-conversation equipment does not need to be upgraded.Furthermore, the multiple systems can be synchronously used, and
data information between the two systems can be transmitted via the antenna.
