Solid Vibration Gyro's Static Zero Point Data Acquisition And Attitude Simulation

Attitude measurement system is widely used, for example, it could be used in aero plane, missiles, satellite attitude control in military parts, and it could also be used in well measurement and electronic stability program of automobile electronics in civil parts. Gyro is absolutely necessary in inertial attitude measurement system, and its accuracy will influence the attitude measurement affection, so, it is very necessary to do research on the theory of gyro, improve its accuracy and design corresponding attitude measurement system.The research work in this article is mainly in the flowing parts:1. According to the result of gyro's temperature experiment, we know that the gyro's static zero point output voltage varies with temperature seriously, we propose the way of BP network to compensate the gyro's static zero point drift. This method is very functional in non-linear mapping and it could reduce the output error of solid vibration gyro, we compare the result with the result of traditional method, it is proved by the experiment that this method could reduce the gyro's static zero point output error even we do not change the gyro's structure, so we could apply this type of gyro to media-high accuracy system.2. We design the gyro's data acquisition system (slavers), this is the source of the data, when the gyro send the data, it needs to be processed until it is sent to the master, this cortical will introduce the whole process of how to choose the apparatus and its function, the circuit diagram of the slaver, and how to process the date in SCM, and send the date to master.3. When the slave is design , the date will be send to the data , this article will introduce how to program in VC to realize the serial communication, including serial communication protocol, communication method, data transmission, and how to receive the attitude data from the gyro.4. When the data is send to the master, we need to design corresponding program to embody the data, it needs to make the model of the gory, and show its attitude, this article will introduce the process of using OpenGL to make the gyro's 3D model in VC, and how to use the data from the slaver to control the gyro's 3D attitude, it realize the gyro's attitude simulation.
