Preceding camera 2 and back camera 3 divide and establish both sides around helmet body 10, and microphone C sets up in helmet body 10 front side edge bottom, and preceding camera 2, back camera 3 and microphone C all are connected with main control board 1. Specifically, as shown in fig. 3, in this embodiment, the main control board 1 takes a DSP chip with a model number a5401A _ ELQFP128 as a core, and is capable of performing encoding and decoding processing on a video. When the portable electronic device is applied, a wearer can record the image images of the front and the back of the portable electronic device through the front camera 2 and the back camera 3, simultaneously the microphone C picks up environmental sounds, and the collected image images are stored on the pluggable TF memory card on the main control board 1 after being operated and processed through the DSP chip. The storage mode is an infinite loop video recording mode to save the latest picture influence in real time, and does not occupy the storage space of the TF memory card. Of course, it is also possible to record by taking continuous video recordings to preserve the picture impact of the wearer throughout the activity. A switch button (not shown) is provided at the front bottom of the helmet body 10, and the wearer can start the front camera 2 and the rear camera 3 modules to record images simultaneously through the switch button.
The main control panel 1 is also wirelessly connected with a mobile phone of a wearer through the WIFI module 6, and a WIFI switch (not shown) is arranged at the bottom of the front side of the helmet body 10. Specifically, as shown in fig. 4, what this WIFI module 6 adopted is that the model is RTL 8189's wireless WIFI module, and its performance is high, the low power dissipation, small and compatible high, can be fast, convenient and cell-phone UNICOM each other. Therefore, the wearer can open WIFI through the WIFI switch to establish WIFI point-to-point connection between the mobile phone and the main control board 1. Thus, the wearer can preview, download, edit and the like the image stored in the TF memory card through the APP in the mobile phone, and can adjust the parameters of the front camera 3 and the rear camera 3. The downloaded picture images can also be shared with videos through social software such as trembling, fast-handed, cool and high-quality videos, watermelon videos, WeChat videos and the like.
Two loudspeaker 4 divide and establish the left and right sides at helmet body 10, and microphone A and microphone B set up in helmet body 10 front side edge bottom, and two loudspeaker 4 and microphone A and microphone B all pass through bluetooth interaction module 7 and wearer's cell-phone wireless connection, and microphone A and microphone B are one to be used for picking up wearer's sound, and the other one is used for discriminating the noise. Specifically, as shown in fig. 2 and fig. 6 to 8, in this embodiment, the bluetooth interaction module 7 includes a bluetooth communication chip 71, an AI voice chip 72, and two power amplifier chips 73. The Bluetooth communication chip 71 adopts a dual-channel Bluetooth chip with the model of AC6925A, the AI voice chip 72 adopts a national core GX8002 ultra-low power consumption AI voice chip, and the power amplifier chip 73 adopts a high-efficiency, ultra-low EMI and 3.0W single-channel D-type amplifier with the model of CS 8302M. The two loudspeakers 4 are connected with the Bluetooth communication chip 71 through the corresponding power amplifier chips 73, and the microphone A, the microphone B and the AI voice chip 72 are directly connected with the Bluetooth communication chip 71.
When the camera is turned on, the Bluetooth communication chip 71 is automatically connected with the paired mobile phone. The wearer can send voice to the mobile phone through the microphone A and the microphone B, and awaken a voice assistant at the mobile phone end to interact, such as receiving and making a call, playing music, playing a novel story, navigating voice, asking weather and the like. Meanwhile, an intelligent voice AI installed at the mobile phone end can be directly awakened, such as AI voice assistants of 'minim' of Baidu cloud, 'tianmaoling' of Ali cloud, 'Alexa' of Amazon and the like to perform man-machine interaction, so that unsafe factors of operating the mobile phone or the helmet in the driving or construction process are avoided.
In order to start the Bluetooth interaction module 7 when starting the front camera 2 and the rear camera 3, a one-way control line for transmitting a switching signal is connected between the main control board 1 and the Bluetooth interaction module 7. Therefore, the camera can be started by setting a switch, and the starting signal is synchronously sent to the Bluetooth interaction module 7, so that the camera and the Bluetooth interaction module 7 are started and shut down synchronously.
