Therefore  it is not the real time processing. This paper introduces a method to quickly determine angle of firing by iteration method  which realizes Runge-Kutta method for the equations of exterior ballistic according to the model of mass center motion of projectile. Moreover  it also provides the flow of real-time integral solution and be proved by the simulation of MATLAB. Its accuracy satisfies the requirements. This work can be as reference for the design of opt-electrical fire control system and the demonstration work. 2012 IEEE.   The design of the data communication and display system based on GeoCOM technology (EI CONFERENCE) 会议论文  OAI收割 2012 5th International Symposium on Computational Intelligence and Design, ISCID 2012, October 28, 2012 - October 29, 2012, Hangzhou, China Geng T.-W.; Wang Z.-Q.; Li D.-N.; Shen C.-W. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 The system is developed for the real-time data processing. The data include the sensor data from TS02 total station and the data from the CCD processing system. It was introduced that the TS02 total station which produced by the Leica company. The GeoCOM application interface which provided by Leica company for the client to exploit it was introduced. The main controller of the system is C8051F021. The protocol of I2C bus is simulated by software. System works in the timing interrupt way. The angle error is calculated and transferred to remote receive device. All data is displayed on LCD. The hardware and software design method is present. The system has been applied to the angle monitor equipment. The system is stable and reliable in practical application. 2012 IEEE.   A signal process system for photoelectric encoder based on C8051F021 MCU (EI CONFERENCE) 会议论文  OAI收割 2nd World Congress on Computer Science and Information Engineering, CSIE 2011, June 17, 2011 - June 19, 2011, Changchun, China 作者:  Gao X. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 In order to minimize the size of photoelectric encoder  a signal process system was designed and C8051F021 MCU was its core device. To begin with  the processing electrocircuit and the data processing software used for the 16-bit encoder was developed. Then the feasibility of this system was verified by experiment. The experimental result proves that the signal process system was simple in structure and reliable. The size of the electrocircuit was 40mm.The precision of the 16-bit photoelectric encoder is 22.4". 2012 Springer-Verlag Berlin Heidelberg.   A novel miniature absolute metal rotary encoder based on Single-track Periodic Gray Code (EI CONFERENCE) 会议论文  OAI收割 2012 2nd International Conference on Instrumentation and Measurement, Computer, Communication and Control, IMCCC 2012, December 8, 2012 - December 10, 2012, Harbin, Heilongjiang, China 作者:  Sun Y.;  Yang S.-W.;  Sun Y.;  Wan Q.-H. 收藏  |  浏览/下载：28/0  |  提交时间：2013/03/25 In order to improve the resolution and enhance the impact resistance and vibration resistance of encoders  a novel absolute metal rotary encoder based on Single-track Periodic Gray Code is presented. The configuration and working principle of the encoder is introduced  and then the metal code disc which can realize full scale absolute encoding on one single track and its corresponding metal slit disc are proposed. Finally  the data acquisition and processing system based on FPGA of encoder is presented. The resolution of the encoder can reach 5.27through electronic subdivision and calibration between the precision code and the coarse code with its volume only 4840mm. The encoder has some advantages such as small volume  low cost  high resolution and strong impact resistance. 2012 IEEE.
