            The following main problems of Ji'nan punching word:


            (1) installed outdoors, often the sun and rain, the wind blew the dust cover, poor working environment. The electronic equipment is wet or damp will cause serious short-circuit faults caused by fire or fire, or even losses;


            (2) Ji'nan punching word may be affected by the strong electric magnetic attack caused by lightning;


            (3) the ambient temperature changes greatly. The display work itself must have a certain amount of heat, if the ambient temperature is too high and the heat radiation and the bad, integrated circuit may not work properly, even burned, so that the display system can not work properly;


            (4) wide audience, visual, far vision requires wide; changes in ambient light, especially sunlight may.


            According to the above requirements, Ji'nan must do the punching word:


            (1) combination of screen and screen and the building must be strictly waterproof leak; the screen body should have good drainage facilities, water can be discharged smoothly once;

            (2)在濟南沖孔字及建筑物上安裝避雷裝置。顯示屏主體和外殼保持良好接地,接地電阻小于3 歐姆,使雷電引起的大電流及時泄放;

            (2) install lightning protection devices in Ji'nan and punching word building. The display main body and the housing to maintain a good grounding, grounding resistance of less than 3 ohms, the high current caused by lightning discharge time;


            (3) the installation of ventilation cooling equipment, the internal temperature of the screen body between -10 to 40 DEG C. Behind the screen is installed above the axial flow fan, exhaust heat;


            (4) the choice of industrial grade integrated circuit chip working temperature between -40 to 80 DEG C, prevent winter low temperature so that the display screen can not start. ;


            (5) in order to ensure the environmental light under the strong visual distance, must use the ultra high brightness light-emitting diode;


            (6) the display medium selection from the perspective of new type wide tube, wide viewing angle, pure color, harmony, life more than 100000 hours. The outer package for punching Ji'nan word is currently the most popular band along the square cylinder cover, silicone seal, metal assembly; its appearance is exquisite and beautiful, durable, can prevent direct sunlight, dustproof, waterproof, anti high temperature, anti short circuit "five anti".
