Application of VxWorks Real-Time System in Firepower Control Software of Missile Weapon System

To improve the real-time operation and its reliability of the firepower control system in some missile weapon system,the VxWorks embedded real-time operation system was used in the software design of the firepower control system. According to the relationship among various tasks,the main operation flowchart was given,and so were the receiving and transition of the inner and outer data,software operation sequence,time calibration,message rolling,database design.The characteristics of this design were introduced also.The operation experiment result of the missile weapon system showed that the software of the firepower control system operated stably and reliably,and the transfer of the control state was clear and controllable.
