Design And Implement Of Software In Ship-borne Satellite Sntenna

This paper is based on a project named ship-borne satellite antenna, which is take place in the satellite communication laboratory in Nanjing University of Posts And Telecommunications(NUPT). The antenna project starts from May 2014 to March 2015. A similar antenna has been implemented in 2008, but the the seniors used in antenna is differ, and main control board changed, too. So the whole software system needs to be redesigned and debugged.Servo system’s main task is using the micro controller with some other peripheral chips, collecting various sensors’ information, drive 5 motors, make antenna always point to the satellite while the ship is shaking.The realization of software is the main line of this paper. The whole software system will be implemented from zero. And it will be optimized. So there is no need to introduce all hardware before head. In the order of the software’s inplememtation, the associated hardware will be introduced, hardware’s features, hardware connection and its driven compilation will be disscussed. This helps the reader understand the whole software system step by step, especially to that who want to continue to study the software system and the make it better.This paper realized the CPU configuration, serial ports program, sensors’ program, peripheral chips’ s driver, antenna servo, switch among antenna’s states, configuration and monitoring software. Configuration and monitoring software is based on the real demand. The antenna’s working states and all kinds of parameters can be sent to the monitoring software by serial port, the software show the data in the form of curve. This method makes antenna debug much more convenient, improved the development and research speed.
