Research on algorithms of land-to-air missile launch control system based on CAN bus

In terms of the characteristics of CAN bus in the launch control system and the messages transmitted in network, a scheduling algorithm which is combined with Deadline Monotonic and Distributed Priority Queue scheduling algorithm is presented. The method is based on the CAN bus's rule of priority's arbitration bit by bit without destroy. Finally, the tracking simulation is carried out on the MATLAB platform, results show that it improves the transmission efficiency of CAN bus.
