Car mounted tablets generally refer to those that can be used on vehicles, but different vehicles have different performance requirements for tablets. The design of Qianhai Gaole‘s car mounted tablets generally needs to meet the needs of special vehicle applications, and there are many requirements for their functions. In addition to the number of commonly used serial communication, USB, and network interfaces, the following basic requirements must be met..
1. Falling: The on-board tablet terminal is installed and fixed in the central control or any other position, with a low probability of falling. The terminal has a basic anti falling ability of 1.5 meters, and has undergone 6 free fall tests 12 times. The device is undamaged every time it lands, and can be used normally
2. Waterproof: The vehicle mounted flat panel terminal is used inside the vehicle, and its position is fixed. It has IP67 basic splash resistance, as many special vehicles are used in different environments, such as agricultural machinery, mining vehicles, etc., which are directly exposed to rainwater.
3. Processor and memory: It needs to reach domestic processors such as RK3288 or even systems, with a running memory of 4GB or above. It needs to run applications and support facial recognition algorithms or fingerprint recognition.
4. Storage: While meeting the basic application requirements, it is also necessary to store driving record videos and achieve eMMC5.1 reading and writing speed.
5. Operating system: Android6, with open root privileges for product customization and development
6. Screen: National Display 10.1-inch screen with backlight LED highlight of 350 lumens
7. Communication: Supports 4G full network connectivity, built-in SIM card, WiFi, Bluetooth
8. Power supply/interface: Supports Type-c USB, and connecting to ACC power supply is beneficial for vehicle start stop monitoring; The power supply cannot use a DC interface and must be fixed to the terminal as a whole.
9. Battery: BMW head DC10V~24V, which can keep the equipment working normally when the vehicle is stopped and resting (the driver‘s resting time is about 20min).
10. Positioning: It needs to be equipped with a vehicle standard GNSS module, which requires BDS/GPS dual mode high-precision positioning, and the built-in module has no redundant wiring harness.
11. Audio: It needs to be equipped with a built-in speaker, with clear and clear pronunciation, up to 100 decibels, a volume adjustment button, and dual MICs to ensure voice function.
12. Camera: External facial recognition infrared monocular camera, which needs to be installed in front of the driver for facial recognition.
13. Wide temperature requirements: In China, the vast majority of vehicles are located in subtropical and temperate regions, with a vast area. The natural temperature environment of the vehicle can range from -20 to 70 degrees Celsius, which is also an assessment for on-board computer equipment.
In addition to interfering with signals, it is unlikely that the application of special vehicles will only have one electrical device, especially police vehicles and medical vehicles. Unqualified electromagnetic wave radiation can have a serious impact on other machinery and equipment, such as digital radio stations, high-precision clinical symptom detection of medical equipment, etc.
