As depicted in figs. 1 and 2, Fig. 1 is that the structure of the intercom recording system using bluetooth recording of the utility model is shown
It is intended to；Fig. 2 is the functional block diagram of the intercom recording system using bluetooth recording of the utility model；It is a kind of to be recorded using bluetooth
Intercom recording system, including intercom 1, mobile phone 2 and monitoring computer 3；It wherein, include MCU module 11 in intercom 1, right
Say module 12, bluetooth module 13, memory module 14 and display module 15；Intercommunication module 12, bluetooth module 13,14 and of memory module
Display module 15 is connect with the electrical connection of MCU module 11 and signal respectively；There is PCM driving unit, intercommunication mould in intercommunication module 12
Block 12 is electrically connected with bluetooth module 13 by pcm interface and signal is connect.Memory module 14 is electrically connected and believes with bluetooth module 13
Number connection, so that the received voice data of intercommunication module 12 is transferred to the APP of mobile phone 2 or monitoring computer 3 by bluetooth module 13
On.
Fig. 2 is please referred to, intercommunication module 12 is used to receive the voice data of intercommunication both sides；Bluetooth module is for receiving MCU mould
The record command of block 11 simultaneously establishes voice data receiving path with intercommunication module 12, and intercommunication module 12 is for receiving MCU module 11
Send instructions and the voice data sent or received is sent to bluetooth module 13 by the voice data receiving path, it is blue
The memory module that tooth module 13 is used to receive MCU module 11 instructs and establishes voice data transmission path with memory module 14, blue
