LED display screen mine flameproof and intrinsically safe explosion-proof display screen

  LED display screen mine flameproof and intrinsically safe explosion-proof display screen can modify the display content through computer
The LED display screen at belt transportation roadway, flameproof and intrinsically safe explosion-proof display screen at roadway damper, heading safety warning display screen and LED display screen at the turning of drift locomotive can modify the display content through computer and USB flash disk
The display content can be customized, and the font color can be selected
The manufacturer's sales telephone is 13325190775, manager Wang
  Therefore, our company took the lead in designing and developing mine flameproof and intrinsically safe LED display screen for the underground environment of coal mine, and achieved Ma mark recognition and explosion-proof qualification

Functions and characteristics of LED display screen
(1) Rich and colorful text information release forms; On the one hand, the display screen can be used for information release, on the other hand, it can publicize safety knowledge

(2) There are many broadcast modes, such as translation, scroll, rotation, scratch, pull screen, single / multi line translation, single / Multi line up / down, left / right pull, up / down, page turning, moving, rotating, shrinking, zooming in, flashing, windowing, etc
(3) The display screen adopts flameproof and intrinsically safe design, which is light and thin, easy to install and hang;
(4) The built-in SD memory card facilitates the timely update of information and large capacity internal storage
The display content can also be modified through RS485 communication with the computer

The LED display screen has a variety of input modes for selection
Through simple setting, it can be used as a safety warning signal at winch transportation roadway, cable car transportation roadway, belt transportation roadway, roadway damper, heading head and roadway locomotive turning
When the product sends out voice prompt, the LED display screen will display the red alarm content
After the alarm stops, the LED display screen will display the green warning statement and the current date and time
The LED display has RS232 communication interface, and the display content can be modified by computer
