Technical Requirements For On-board Computers

On-board computers, especially for special vehicles, have many general functional requirements, in addition to the number of common serial ports, USB, and network ports, they are particularly sensitive to the following specifications:
Seismic requirements: needless to say in the on-board environment, no matter any vehicle has vibration, according to the use of the object has high acceleration large amplitude, low acceleration small amplitude.
Display requirements: Because the car is used outdoors, sunlight deflection or even direct exposure to the environment cannot be avoided. This needs to be minimized by choosing high-quality displays or structural designs.
Power performance: The on-board computer generally takes power directly from the on-board battery, because the use status of various batteries is different, plus the instantaneous impact of ignition and flameout, so the power supply requirements for the equipment are very high. Otherwise, it is very easy to damage the device.
Wide temperature requirements: most of China is in subtropical and temperate regions, vast territory, vehicle temperature environment extreme, from -30 to 70 degrees Celsius are possible, which is a test for on-board equipment.
Electromagnetic interference: The use of special vehicles cannot be only one electrical equipment, especially police and medical vehicles. Unqualified electromagnetic radiation will bring serious interference to other equipment, such as digital radio, medical high-precision sign monitoring, etc.
Function buttons: With the function buttons, in the unstable car environment, it can bring great convenience and improve the efficiency of use.
