Product description

● The system has the characteristics of high cost performance, high reliability, long life, easy installation and use. The smallest unit display module package can be arbitrarily spliced ​​into a larger size display screen without adding a protective shell.
● The system adopts self-healing optical fiber network, and all information is digitally transmitted. It has the advantages of long communication distance, high reliability, anti-interference, lightning protection, etc., and can be well applied to emergency communications in highways, mine tunnels, etc. occasion.
● The combination of display terminal is flexible, the display unit can work independently, and can also be composed of various sizes of display screens with no more than 64 basic units according to needs. Information release is convenient, and the information release supports multi-region screen and text editing and display, which can display the same content on all terminals or release different information separately according to needs.
● The system has an environmental parameter monitoring function, which automatically collects and displays the current environmental parameters (CH4CO, 0:, HS, ℃, RH) when there is no information to be released.
● The system has public voice broadcast and two-way voice intercom functions. Public broadcasting functions such as background music, daily broadcasting, emergency notification, etc. can be completed simultaneously with the release of LED information or separately. When needed, the underground personnel can make a voice intercom call with the management center.
