The Design Of Controller For Broadcast Television Monitor

The monitor frontend of broadcast television is the basic composition unit of a broadcast television monitor network,and the controller is the core of the entire monitor front end. The traditional design method is run the general-purpose WINDOWS operating system to take the controller, but WINDOWS operating system itself is, the stability which designs for the tabletop application is not very good, frequently needs artificially to maintain, also when appears the power lost suddenly is very easy to cause the WINDOWS operating system to collapse, but monitors usually all is nobody value defends, when the power will lost is does not have the guarantee, this gives front end the monitor the long-term stable and the maintenance brings the question.In view of these questions, this article designed a controller based on the embedded LINUX system, the hardware uses the ARM processor, the software run the embedded LINUX operating system, the overall system put on in a piece of flash memory, whenever the power lost cannot cause the system to collapse, after power on the system self-recovery normal work, did not need any maintenance.
