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.
