Vxworks-based Concept Aiming Control System Research

The increasingly complicating battlefield environment requests more intelligent and automotive weapon devices. As an important component, the sighting system has great influence on the performance of anti-aircraft gun system. Conformed the technology of embedded software and hardware, image processing and field-bus, we design and debug a full functional sighting system based on Vx Works operating system and PC/104. The system has the functions of tracking target and track solving. The system connects the servo systems with the CANopen field-bus to control them.Based on the requirements of system, firstly a platform for developing the system is deployed by configuring the Vx Works operating system and debugging related functional block; based on this platform, we implement and compare the performance of spatial edge orientation histogram based Mean Shift tracking algorithm and center-of-mass algorithm, Then a human-machine interaction function is realized by taking advantage of multi-task management mechanism and WindML of Vx Works. At last, in order to realize follow-up control function, we transplant fire-control algorithm which includes data acquisition, coordinate switching and solution of control value; and implement device drivers for CAN-bus, define and code CANopen protocol, design and realize communication system for servo control and nodes monitoring.
