            濟南沖孔字的主要問題如下:

            The following main problems of Ji'nan punching word:

            (1)安裝在戶外,經常日曬雨淋,風吹塵蓋,工作環境惡劣。電子設備被淋濕或嚴重受潮會引起短路甚至起火,引發故障甚至火災,造成損失;

            (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)濟南沖孔字可能會受到雷電引起的強電強磁襲擊;

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

            (3)環境溫度變化極大。顯示屏工作時本身就要產生一定的熱量,如果環境溫度過高而散熱又不良,集成電路可能工作不正常,甚至被燒毀,從而使顯示系統無法正常工作;

            (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)受眾面寬,視距要求遠、視野要求廣;環境光變化大,特別是可能受到陽光直射。

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

            針對以上特殊要求,濟南沖孔字必須做到:

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

            (1)屏體及屏體與建筑的結合部必須嚴格防水防漏;屏體要有良好的排水措施,一旦發生積水能順利排放;

            (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)安裝通風設備降溫,使屏體內部溫度在-10℃~40℃之間。屏體背后上方安裝軸流風機,排出熱量;

            (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)選用工作溫度在-40℃~80℃之間的工業級集成電路芯片,防止冬季溫度過低使顯示屏不能啟動。;

            (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)為了保證在環境光強烈的情況下遠距離可視,必須選用超高亮度發光二極管;

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

            (6)顯示介質選用新型廣視角管,視角寬闊,色彩純正,一致協調,壽命超過10萬小時。濟南沖孔字的外封裝為目前最流行的帶遮沿方形筒體,硅膠密封,無金屬化裝配;其外型精致美觀,堅固耐用,具有防陽光直射、防塵、防水、防高溫、防電路短路“五防”特點。

            (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".
