The text STM32F103ZET6 single-chip microcontroller control radio-frequency module is identical；User wants to send voice under such state, it is necessary to
Say level-one password first, until reply after, talk, such state be relatively suitble to have it is slightly critical, but get something else on need
When handling, discontinuous call is carried out；After usage, password mode key, the signal of password mode key are pressed again
Output end becomes high level from low level, and the PE10 pin of STM32F103ZET6 single-chip microcontroller recognizes password mode key and is in
Off-state, the present apparatus switch to listen to state；
If when wanting using manual triggering mode, it is desirable to send voice and then press triggering mode key manually, trigger manually
The signal output end of mode key becomes low level from high level, and the PE11 pin identification of STM32F103ZET6 single-chip microcontroller is in one's hands
Dynamic triggering mode key is in down state, presses then state due to self-lock switch and is locked, until down state just changes again
Become, STM32F103ZET6 single-chip microcontroller, which recognizes, is now in manual triggering mode, and the PE15 of STM32F103ZET6 single-chip microcontroller draws
Foot exports low level, and control audio collection module work, control principle and STM32F103ZET6 single-chip microcontroller described above control sound
Frequency acquisition module working principle is identical, speaks to finish and presses triggering mode key manually again, STM32F103ZET6 single-chip microcontroller
PE15 pin exports high level, so that audio collection module does not work, control principle is same as above,
STM32F103ZET6 single-chip microcontroller will receive the audio of acquisition, be sent by radio-frequency module, the control of STM32F103ZET6 single-chip microcontroller
Radio-frequency module is identical as control principle described above；Such state, user often want to speak, it is necessary to press manual triggering mode
Key, this kind of state are relatively suitble to use when thing is not urgent；
When control device mode key is pressed, the signal output end of control device mode key becomes low electricity from high level
Flat, the PE11 pin of STM32F103ZET6 single-chip microcontroller recognizes control device mode key and is in down state, is opened due to self-locking
Pass is pressed then state and is locked, until down state just changes again, STM32F103ZET6 single-chip microcontroller, which recognizes, to be now in
Control device mode, STM32F103ZET6 single-chip microcontroller are communicated with intercom ontology by wired or wireless network,
STM32F103ZET6 single-chip microcontroller passes through LD3320 speech recognition module identification control password, STM32F103ZET6 single-chip microcontroller control
The control principle of LD3320 speech recognition module processed is same as above, and LD3320 speech recognition module at most can recognize 50
Sentence password is merely able to identification mandarin, and not bery standard is good, and recognition principle is phonetic identification, and then STM32F103ZET6 is mono-
Piece machine realizes the corresponding control to intercom；If control device mode key is pressed again using finishing,
The PE11 pin of STM32F103ZET6 single-chip microcontroller recognizes control device mode key and is in close state.
