摘要
通过对TOA技术、TDOA技术及AOA技术等几种典型测距定位技术的比较,提出了一种新型测距定位技术,即伪码测距定位技术。分析各种定位技术的优缺点,指出伪码测距定位技术更加适合油田火灾定位系统;基于伪码测距定位技术,设计出油田火灾定位系统结构,并基于Matlab工具,建立了油田火灾定位系统的数学模型;最后通过Matlab仿真,考虑各种可能因素,模拟输入环境和输入信号,分析系统输出结果,从而验证了系统设计的正确性和可行性。
By comparison of several distance measurements, such as TOA, TIX）A and AOA, a new positioning technology is proposed, it is called PN code ranging positioning technology. By analyzing the advantages and disadvantages of various positio ning technologies, PN code ranging positioning technology is more suitable for oil fire positioning systen~ Based on the PN code ranging positioning, the structure of the oil fires in the positioning system is designed. Then, based on Matlab instruments, the mathematical model used in the fire positioning is set up. Finally, through Matlab simulation, every possible factor is consi dered. After the input environment and the input signal are simuiated, the output of the system is analyzed, with the correctness and feasibility of the design being tested.
