| Abstract: | The 1553B bus is a bus standard widely used in information transmission among airborne instruments. The 1553B bus protocol is presented in brief. Taking a certain airborne visible light camera as an example, the compoments of the camera system, their functions and system joint mode are presented. Both a TMS320F2812 chip and a B61580 chip are used in the design of a 1553B communication module and the procedure to embed the 1553B software module in the main control software of the camera is illustrated. This method is stable and reliable and can meet the design requirements of the camera system. |
