Car TV advertising as an emerging industry, has been focus community, attracting more and more companies jump. With the development of mobile TV advertising, car TV equipment manufacturer also sprang up in development, but as the industry standard is missing, causing the manufacturers of equipment varies greatly, serious constraints on the development of the industry, the industry calls for industry standards as soon as possible, Dalian East huaxun digital by virtue of its three years of development experience, pioneered the "car TV technical standards".
I. monitor
Standard a shell is beautiful, durable and lightweight material, the following point taking a sharp corner shape that you want to display the screen to take certain protective measures.
Standard 2-voltage design with wide voltage section to accommodate the change in voltage (voltage range 6-14V);
Various interfaces to firm, insurance;
RoHS (lead free) standards;
With full remote control.
Standard three-screen selection: brightness more than 450cd/m2, response time is not greater than 25ms, under the perspective of not less than 60 degrees.
Standard Quad-monitor stand firmly with monitor installation requirements, cannot be met.
Second, the host
Standard a host should use full metal jacket, extrusion, anti-jamming, easy to install.
Standard II chassis and lock to be safe, reliable, and switch convenience.
Standard three switches should be connected to the power port, pressure should not be less than 125V, 10A.
Standard four must be in the power installed device. Fuse selection, rated voltage should be greater than the machine's working voltage, rated current = current/fuse reduction rate.
Standard five use AV signal transmission, avoid long-distance transmission, signal attenuation and interference.
Standard 6 uses the electronic storage media, solve the problem of earthquake preparedness, panic.
Standard seven-wide voltage design: diesel car (24V) input voltage range at least 14V ~ 36V;
Gasoline vehicles (12V) input voltage range at least 8V ~ 20V.
Standard eight-diesel car (24V) start current to less than 3A, power consumption is less than 55W.
Gasoline vehicles (12V) start current to less than 4A, power consumption is less than 55W.
Standard nine requirements play a sound balance not shrill, audio output ≥0 2W× 2.
Standard 10 calls for speakers RADIUS (0.5m) wide volume should be greater than 60dB less than 70dB.
III. installation
Standard a to in car distribution box for electric, require compliance with QC/T423-1999 auto electric Terminal marked "standard.
Standard 2-wire and cable connections must be welded, and good insulation measures.
Standard three power cord diameter requirements for diesel vehicles (24V) use 1.0mm2 above gasoline vehicles (12V) use 1.5mm2 above.
Standard four audio signal cable 0.5mm2 wire diameter requires more.
Standard five video signal cable requires the use of high-quality shielded cable (75 Ω).
