Further, including recorded speech reservoir module and voice playing module, the voice playing module can be from
The voice messaging recorded sequentially is read in the reservoir module of recorded speech and real-time continuous exports and gives audio hub module.
Further, audio hub module include active signal detection sub-module, Digital Signal Processing submodule, triggering it is short
Language detection sub-module and triggering phrase output sub-module,
Active signal detection sub-module whether there is active signal in the audio electrical signal suitable for continuing to monitor input,
The audio electrical signal with activity description that Digital Signal Processing submodule is suitable for input carries out digital-to-analogue conversion,
Phrase detection sub-module is triggered to be suitable for being joined according to built-in local speech recognition engine and preset keyword/key phrase
It examines template and matching primitives is carried out to the aforementioned audio electrical signal after digital-to-analogue conversion, to detect keyword/key phrase,
Triggering phrase output sub-module is suitable for exporting keyword/key phrase of detection to microcontroller in real time.
The beneficial effects of the invention are as follows：
Agriculture sand table system in the present invention has crucial voice detection function, when in artificial explanation to predetermined keyword/key
When phrase, the keyword/key phrase can be detected in real time and color lamp is controlled by microcontroller combination color-light controller
System.Such as when explaining to " No.1 greenhouse area ", the color lamp in No.1 greenhouse area is flickered or is lighted in agriculture sand table system in the present invention.
In addition, agriculture sand table system can also play prerecording explanation voice document in the present invention, can equally reach
State functional effect.
Compared to traditional sand table system, when replacing explanation content, without being reset to color light control logic.
