Abstract
The multiple information is synchronous displayed on the multiple LED display screens inside or outside the vehicle by setting up the information controller through the open type multi output interface circuit. The information controller can communicate to the multi display screens through direct parallel connection mode or indirect in series mode. The screen includes the CPU programmable controller and EPROM memory connected to the data input receiving circuit, which receives the display command and data sent out by the information controller in order to operate the display of the LED array. The information controller includes the short message receiving circuit of the mobile communication, the multiple interfaces circuits and cards. Thus, the latest news downloaded from Internet, PC, and through the interface circuit can be communicate with the data receiving circuit so as to display the information on the LED screen.
Description
Technical field
The present invention relates to a kind of by INTERNET net and SMS messaging breath mobile communication reception information, on mass transportation facilities, realize multi-screen ganged LED display unit, be mainly used on the facilities such as mass transportation facilities, loudspeaker van, subway, aircraft, yacht, provide in good time information and knowledge to the passenger.
