航磁姿态数据收录系统设计

Design of Air Magnetic Attitude Data Collection System

随着计算机的发展,航空磁法测量的磁补偿方式已从手动补偿转变为自动补偿方式,其磁补偿干扰系数的计算,也在补偿标定飞行中自动完成,磁补偿系数的准确程度是由标定飞行所完成动作(摇摆、俯仰、偏航)的准确性来决定,因而对飞机姿态角度的数据记录和显示,可以为航磁补偿质量的评价提供一种依据,还可以在测区做业的数据处理中,检查航磁探头在测区中工作角度的变化,排除航磁探头进入到死区内的干扰数据;因此在航空物探测量中对飞行姿态数据的采集是很有必要的,该软件应用C++Builder编译系统,实现了在航空磁法测量中对航磁数据、GPS数据、飞行姿态动作数据的实时采集、记录和显示,也为补偿软件的开发提供飞行姿态数据的支持。

With the development of computer,the method of magnetic compensation in the airborne magnetic survey has been changed from manual compensation to automatic compensation.And the calculation of interference coefficient inmagnetic compensation is also done during the compensation calibration flight.Due to the accuracy of the magnetic compensation coefficient is determined by the accuracy of the action(swing,pitch,yaw),the recording and displaying of the aircraft attitude angle data can provide basis for the evaluation of the quality of aircraft magnetic compensation.From the data processing of the survey area,it can check how the working angle of the aerial magnetic probe changes in the measurement area,so we can avoid the interference caused by the aerial magnetic probe in dead zone.Therefore,it is very necessary to collect the flight attitude data during the airborne geophysical survey.This software is based on C++Builder compiler system,it not only lets the real time data collecting,recording and displaying of airborne magnetic data,GPS data and flight attitude motion data during the airborne magnetic survey come true,but also provides support for flight attitude data in the development of compensation software.
