摘要
利用数字电子罗盘HMR3000,AT89C51单片机及L290/L291/L292专用芯片组成了森林防火红外成像监测指挥车的飞艇姿态稳定控制系统。飞艇在高空外界因素的影响下所发生的航向、俯仰及倾斜角的变化信息,通过HMR3000的检测输送给AT89C51,AT89C51再根据HMR3000的检测信息及反馈信息控制安装在飞艇左右机翼及尾翼上的伺服电机工作,保证飞艇在高空的姿态稳定,提高林火监测地理位置的准确性。
With numerical electronic compass HMR3000, SCM AT89C51 and special chip L290/L291/L292 the steady control system of airship's posture is assembled in the fire prevention monitor conduct car with the infrared ray figuration. When the airship working at a high altitudes with the outside factors influence, the change of directions, stoop and lift up, the variety of the gradient can be examined by HMR3000, and all the messages are transmitted to AT89C51, which, based on the examination and feedback messages, control the serve electrical engineer that are fixed on the wings and tail wings at work, and make sure that the posture of airship is steady in highflying and thus heighten the accuracy of fire prevention on investigating the geographical position.
