Riding a horse in the desert, the wind and sand cannot conquer me

1.Touch all-in-one machineThe whole machine can sense and automatically adjust the screen brightness to achieve different brightness levels in different lighting environments
Display effect, this function can be turned on or off by oneself.

2. The whole machine screen adopts an 86 inch UHD ultra high definition LED LCD screen with a display ratio of 16:9, and the screen

3. The whole machine adopts a full metal shell design, with curved corners and no sharp edges or protrusions on the surface.

4. The embedded system version shall not be lower than Android 9.0, with memory ≥ 2GB and storage space ≥ 8GB.
5. Deploying a single Ethernet cable can achieve wired network connectivity between Android and Windows dual systems.
6. The thickness of tempered glass is ≤ 3mm, and the surface hardness of tempered glass is ≥ 9H.
7. Adopting infrared touch technology, supporting 20 or more touch points in Windows system, supporting
Infrared pen writing.
2、 Main functions:
1. The whole machine is equipped with a 2.1-channel speaker with a rated total power of 50W. It has a front facing 2 * 15W mid to high frequency and a back facing sound
Towards 20W bass.
When the writing height does not exceed 2mm, that is, when the distance between the touch object and the outer surface of the glass does not exceed 2mm,
Touch operations can be recognized, and when the distance exceeds 2mm, touch operations will not be recognized; guarantee
When writing, if the touch object is more than 2mm away from the outer surface of the glass, the next stroke of writing can begin.
3. The color gamut value of the entire machine screen is ≥ NTSC 90%.
4. The whole machine adopts zero bonding technology, and the gap between tempered glass and LCD display layer is less than 1mm, reducing the display surface
The polarization and scattering between the board and the glass result in clearer and more transparent image display, as well as a wider viewing angle.
5. The whole machine adopts a simplified design, with independent physical buttons that can be easily pressed to achieve energy-saving screen off/wake-up,
Press and hold the button to shut down.
6. The whole machine adopts a virtual button design on both sides of the left and right sidebars, and the volume+/- and brightness can be called through the sidebars
Degree+/-, annotations, homepage.
7. Built in wireless screen receiver, no external receiver required, wireless screen transmitter matched with the whole machine
After that, the screen transfer function can be realized, and the screen image of the external computer can be wirelessly transmitted to the whole machine
Display.
8. The whole machine is equipped with a built-in wireless network module, and the PC module has no external or adapter antenna or network card that can be connected
Wi Fi wireless internet connection and AP wireless hotspot transmission.
Both Wi Fi and AP hotspots support dual band 2.4G&5G, meeting IEEE 802.11 a/b/g/n/ac requirements
Standard. The working distance between Wi Fi and AP hotspots should not be less than 12 meters.
10. The whole machine is equipped with a non independent high-definition camera with a field of view (FOV) of ≥ 120 degrees.
11. The built-in camera has a pixel count of ≥ 8 million and supports remote course inspection applications.
12. The whole machine has a built-in camera (not an external expansion), and supports calling the camera through video booth software on the PC channel
Scan the QR code with the head for recognition.
13. The whole machine is equipped with a non independent external expansion array microphone, which can be used to collect audio from the classroom environment
Collection.
