Abstract


Increasingly complex modern battlefield environment requires more information , automated on-site weapons configuration , control system and observation altitude antiaircraft weapon system is an important component of its weapons systems tactical and technical index has a critical influence . Based on the embedded hardware and software , digital image processing , real-time bus communications technology research and integration to the VxWorks operating system platform for the development and PC/104 module , the design of a more complete and observation function control system , complete prototype debugging. The sighting system with automatic target tracking and track solver functionality while connected via the bus system to achieve multi-node servo servo control . Based on the functional requirements of the system , the paper first build a sighting control system hardware and software control platform , including VxWorks operating system configuration and various functional modules in the function under VxWorks debugging ; based on this platform is implemented based on the edge direction histogram Mean Shift tracking algorithm and key small area centroid tracking algorithm compares the test results of two algorithms , and the final choice based on key small area centroid tracking algorithm has been improved ; followed by the use of the VxWorks real-time multitasking management mechanisms , as well as multimedia library WindML, the control system to achieve a sighting interactive features ; Finally, in order to achieve servo control , fire control system migration and implementation of solver algorithms, including input data acquisition, coordinate transformation , fire solver program implementation , etc., and then write a device driver based on CAN bus and custom CANopen protocol stack, used to connect the servo system to achieve servo control and node monitoring.
