济南冲孔字的主要问题如下:

The following main problems of Ji'nan punching word:

(1)安装在户外,经常日晒雨淋,风吹尘盖,工作环境恶劣。电子设备被淋湿或严重受潮会引起短路甚至起火,引发故障甚至火灾,造成损失;

(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)济南冲孔字可能会受到雷电引起的强电强磁袭击;

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

(3)环境温度变化极大。显示屏工作时本身就要产生一定的热量,如果环境温度过高而散热又不良,集成电路可能工作不正常,甚至被烧毁,从而使显示系统无法正常工作;

(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)受众面宽,视距要求远、视野要求广;环境光变化大,特别是可能受到阳光直射。

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

针对以上特殊要求,济南冲孔字必须做到:

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

(1)屏体及屏体与建筑的结合部必须严格防水防漏;屏体要有良好的排水措施,一旦发生积水能顺利排放;

(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)在济南冲孔字及建筑物上安装避雷装置。显示屏主体和外壳保持良好接地,接地电阻小于3 欧姆,使雷电引起的大电流及时泄放;

(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)安装通风设备降温,使屏体内部温度在-10℃~40℃之间。屏体背后上方安装轴流风机,排出热量;

(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)选用工作温度在-40℃~80℃之间的工业级集成电路芯片,防止冬季温度过低使显示屏不能启动。;

(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)为了保证在环境光强烈的情况下远距离可视,必须选用超高亮度发光二极管;

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

(6)显示介质选用新型广视角管,视角宽阔,色彩纯正,一致协调,寿命超过10万小时。济南冲孔字的外封装为目前最流行的带遮沿方形筒体,硅胶密封,无金属化装配;其外型精致美观,坚固耐用,具有防阳光直射、防尘、防水、防高温、防电路短路“五防”特点。

(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".
