Design of Test System Used for Infrared Earth Sensor Based on P89C51 Microcontroller and Delphi

文中基于P89C51单片机和Delphi,根据卫星用红外地平仪产品研制的特殊性,设计了一套地平仪地面检测系统。该地面检测系统具有RS-232串行通讯、RS-422串行通讯、数据缓冲、电激励信号产生等功能。地面检测系统上位机软件在Delphi集成开发环境下编写调试,人机界面友好、功能强大,可以进行姿态角计算、随机噪声等效角计算、数据存储显示与曲线显示、指令发生、二维转台角度控制。该地面检测系统可以模拟星载计算机对地平仪进行控制、注数和读数等操作,为产品的研制、调试和测试提供了一个半物理仿真环境。

According to the particularity of infrared earth sensor used on the satellite,a test system based on P89C51 microcontroller and Delphi and used on the ground for the infrared earth sensor was designed.Powerful functions such as RS-232 serial port communication,RS-422 serial port communication,data buffer storage,producing electric signal and so on were included in the test system.The upper software was compiled and debugged in the Delphi integrated development environment and had friendly interface and powerful function.Tasks such as calculating attitude angle and random noise equivalent angle,showing data curve and sending out instructions and controlling two-dimensional turnplate could be completed by this upper software.The test system could simulate the computer of the satellite to control the infrared earth sensor and exchange data with it.A semi-physical emulational environment had been offered for producing,debugging and testing.
