Abstract
Observing and aiming equipment is a key part of armed helicopter, by which precise aiming and accurate hitting are implemented. We established a test system on the basis of analyzing the working principle and test requirements of the equipment, with PC/104 embedded system as the core control system. The system uses ARINC429 bus and RS422 master-slave communication to transmit the control commands to the observing and aiming equipment, and receive the data returned by the equipment for self testing, status, indication and parameter. Modularization method is applied to develop the application software. Multi-thread technique and inquiring method are applied to achieve real time test performance. Error control in data communication is carried out by receiving within time and computing check sum. Data communication, real time data processing and results display are integrated in the test system, and the test tasks can be scheduled and controlled by the system.关键词
