[Abstract]:With the development of science and technology, ring laser gyro (RLG), which has good working characteristics and many advantages, has gradually become the ideal core device of the new generation inertial navigation system. The frequency stabilization system is the basic premise of the laser gyro, and the high stability and reliability of the frequency stabilizer has a great influence on the accuracy of the gyro. In the design and production of laser gyro, in view of the complexity of its structure, it is often necessary to collect and process the light intensity data in real time, and a data acquisition and processing system with high reliability is needed. The traditional data acquisition technology is based on PCI and other computer buses, which is limited by the bandwidth of the system bus. In the face of the objective situation of the increased data acquisition rate, it has been in the bottleneck of performance. In this paper, various factors affecting the frequency stability of laser gyro are analyzed, and the common frequency stabilization methods, the advantages and disadvantages of the main technologies and the possible development direction are introduced. A design and implementation method of data acquisition and signal processing based on USB2.O and LPC2368 chip is given. Combined with the data acquisition and transmission equipment based on USB bus, this paper briefly describes the USB protocol, organization structure, transmission mode, data flow type and so on, and introduces the working principle, design principle and design method of WDM driver. A program to realize USB transmission is formed, each functional module of the routine is introduced in detail, and the design scheme of light intensity acquisition and transmission system based on USB2.0 specification is obtained. The design has been used in data acquisition equipment because of its stable performance and reliable transmission. The results of system performance test show that the data transmission process meets the design requirements. The detailed introduction of driver design process has good reference application value for the design and development of USB special device driver.
