The Design And Complement Of Embedded Commanding Communication System Based On War Field Information

Since the new century, we have set the goal to overtake the western world in science and technology of military. With the policy to turn numerical scale to technology-intensive, we have made great achievements in equipment researches. Nevertheless we still lag behind in the communication equipment in the modern troops, which can not suit the needs of information war. Partially it is because that the communication equipment technology can not keep pace with the development of digital information transmission.The development of modern communication equipment in many countries characterized in digital information, circuit highly integrated, miniaturize and so on, which can transmit great information and have many functions. Great achievements have been made in this field and are put into the use of modern war. In order to keep pace with the advanced communication equipment of foreign countries and meet the needs to get through in movement, in interference, in distance in visual field and in single. We centered on embedded technique and helped by DSP real -time digital control and other means of communication which is a programm worthy further study for information transmission during war time.The programm the paper majors in based on the embedded command information transmission hardware for battle field communication , and is discussed in two aspects—VxWorks system transplant and hardware circuit design.First of all,the paper gives a comprehensive description about the significance of the research and and the current status of .VxWorks real-time operation system and embedded processor technique as well as the research orientation. Secondly, the paper gives a concept and the basic status of the embedded real time operation system .The interact program of the embedded real-time operation system and its software is to the accompaniment of VxWorks integrated program which provides perfect and practical edition ,translation and edition, link, source code debugging and other debugging means. Based on the VxWorks embedded real-time operation system package ,the paper describes the transplant and programmatic means of S3C44BOX ARM processor.Finally,the paper gives the description of the system software design and the programmatic idea of low power consumption and modeling in hardware system design .and also describes in detail the circuit design of modeling in DSP processor, ARM embedded processor, SDRAM, double entrance RAM ,FLASH power supply part .It also refers to the disposition to related GSM module and GPS module.
