Small Aircraft CAN bus Signal Acquisition Equipment

摘要：

Small aircraft often used RS485 bus. But with the complexity of the small aircrafts subsystems increase and the progress of field bus technology, CAN bus systems in small aircraft use more and more widely. How to record real-time flight experiment data on the small aircrafts CAN bus and provide test data for reproducing the process of a small aircraft flying is very important. This paper presents a design method of signal acquisition device, as the main chip with DSP2812, SJA1000 as CAN controller, CTM1050 as the CAN transceiver, CF card as storage media. Gives the diagram of its hardware and software design process. Combined with the background of a small aircraft, testing the instrument for data acquisition when the ground experiments and flight progress. Experimental data show that the design of high reliability and CAN signals can effectively complete the record; it can be used for small aircraft flying field experiment.
