fig. 2 is a schematic view of an embodiment of a main component mounting manner of the speech intelligent helmet of the present invention;

the reference numbers in the figures refer to: 1-microphone, 2-USB interface, 3-interlayer, 4-loudspeaker.

Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings 1 to 2.

The utility model discloses a voice intelligent helmet, including the loudspeaker of installing in helmet side auricle department and the microphone 1 below the helmet, helmet shell rear is provided with intermediate layer 3, installs PCB board and the battery of its power supply in the intermediate layer, be the voice control system of control connection with loudspeaker 4, microphone 1 on the PCB board;

the voice control system comprises a main control chip, a memory, a Bluetooth module, a speed sensor and a power management system, wherein the memory, the Bluetooth module and the speed sensor are connected with the main control chip; and a USB interface 2 connected with a power management system and a data line interface connected with a main control chip are also arranged at the rear part of the helmet shell.

Pronunciation intelligence helmet can be when the user wears the helmet, through bluetooth module and cell-phone communication to through speech control, realize the conversation function, also can broadcast and store in advance MP3 music file etc. in the memory, can be used for using under the circumstances such as building site, outdoor bicycle, rock climbing.

Fig. 1 shows an embodiment of a control system, wherein the main control chip of the voice control circuit board can select CI1103, CI1103 is a voice local recognition chip manufactured in quantity by imgtalan corporation, and has the functions of off-line identification and cloud identification, and is provided with a crystal oscillator, the utility model mainly utilizes the off-line local identification function without transmitting audio signals to other servers or the cloud, so that local voice recognition can be implemented in a network-bad environment, the CI1103 also has data processing capability, a plurality of analog or digital signals can be output to control other voice control devices or devices, such as a loudspeaker, a switch tube and the like, an audio coding and decoding controller is integrated in the CI1103, a microphone signal is directly input into the main control chip through a corresponding audio input interface, and an audio analog signal is also directly output to the power amplifier chip through a corresponding interface.

The CI1103 may directly perform signal conversion, interaction, and control on conventional circuit elements such as keys, motors, relays, driver chips, LED display lamps, nixie tubes, key sensing chips, etc., using its own integrated processor, audio codec, I/O interface, and multi-channel ADC channels.

After a user sends a voice instruction, the voice instruction is collected by a microphone to be an analog signal and input to a main control chip, an internal integrated audio decoding chip carries out digital quantization on the analog signal and then sends the analog signal to an internal operation system of a voice local recognition chip for recognition and comparison, the voice local recognition chip CI1103 carries out local recognition and then judges an execution instruction needing to be output through artificial intelligence local calculation, and the execution instruction is synchronously output to a loudspeaker through a sound signal after the instruction is executed to play the audio signal and remind and feed back the user.
