Precautions for automotive industrial tablet applications
On-board computer is a kind of on-board equipment based on intelligent system. Due to the special environment of the vehicle, and the vehicle is a device that requires a high degree of information technology support, such as the information of the vehicle itself, the social and work information composed of the operator and the crew, and the media needs, all need to be processed by a powerful information center. Industrial tablet computers have stable and reliable performance. Therefore, the application of in-vehicle industrial tablet PCs is a solution that meets market needs according to the user's use environment. What are the precautions for the application of automotive industrial tablet computers?One, face up to the environmental problems of vehiclesSince the on-board computer is used in a special environment, its requirements need to be specified:
1. Convenient installation and maintenance: Taking into account the different environments of various vehicles, and the coverage is very large, the personnel involved are also very complicated. Therefore, under certain conditions, it may be suitable for various scenes. For example, it supports the vehicle VESA75/100 standard, and supports RAM brackets.
2. Anti-vibration requirements: Needless to say, in the vehicle environment, no matter any vehicle has vibration, it has high acceleration and large amplitude according to the object of use, and low acceleration and small amplitude.
3. Display requirements: Since the vehicle is used outdoors, it is impossible to avoid deflected sunlight or even direct sunlight. The conventional liquid crystal display is far from meeting the requirements, and it is necessary to minimize the impact of this situation by selecting high-quality displays or structural design.
4. Power performance: The on-board computer generally draws power directly from the on-board battery. Due to the different use states of various batteries, coupled with the instantaneous impact of ignition and flameout, the power supply requirements for the equipment used in conjunction with it are very high. Otherwise, it is extremely easy to damage the equipment.
5. Wide temperature requirements: In China, the temperature environment of vehicles is not good, from -20 to 60 degrees Celsius is possible, which is a test for industrial tablet computers.
6. Electromagnetic interference: It is impossible to use only one electrical device for special vehicles, especially police and medical vehicles. Unqualified electromagnetic radiation will cause serious interference to other equipment, such as digital radio, medical high-precision physical sign monitoring, etc.
7. Heat dissipation performance: The space of vehicle-mounted equipment is small, and industrial tablet computers are required to be fully sealed under the conditions of heat dissipation, without additional heat dissipation holes.
8. IP protection level: According to the different operating environment, rain and dust damage is inevitable. It is a necessary condition for a qualified industrial panel computer to reach or reach a certain IP level.
9. Function buttons: With function buttons, it can bring great convenience in the unstable environment of the car and improve the efficiency of the use of industrial tablet computers.
Which car-mounted industrial tablet is better? Qianhai Gole technology is good, Shenzhen Higole industrial-grade embedded touch panel computer adopts ultra-thin, fanless, shock-proof design, low-power processor. 8-15 inches optional, excellent heat dissipation and rust resistance, Meet various applications of industrial automation.
