摘要
为了改进调炮精度测量方法,对双经纬仪交会测量火炮调炮精度的测量误差和误差抑制方法进行了研究。首先,根据双经纬仪交会测量原理,建立了测量调炮精度的空间解算模型。接着,以DT202C电子经纬仪为例,对影响其测量精度的各项因素进行了系统的定量分析,并建立了测量误差模型。最后,在预先确定炮管上两标记点的前提下,研究了经纬仪最佳布站方式以抑制其测量误差,并采用遗传算法进行了寻优解算。理论计算和试验结果表明,通过经纬仪合理布站,可以使调炮精度的测量误差控制在0.20mil以内。提出的方法满足了试验需求,消除了经纬仪随机布站引起的测量结果的不确定性。
To improve the measurement for gun rotated accuracy,the measurement error and the method to control the error for measuring the gun rotated accuracy by two theodolite intersection were researched.First,according to the principle of two theodolites intersection measurement,a space calculation model for measuring the gun rotated accuracy was established.Then the factors influencing the measurement error were quantitatively analyzed by the DT202C electronic theodolite,and the measurement error model was established.Finally,the idiographic realization method for the theodolite optimal disposition to control the measurement error was researched after predefining two markers on the gun tube,and the optimal disposition place was calculated by genetic algorithm.The theoretical calculation and the test results indicate that the measuring error of the gun rotated accuracy can be controlled within 0.20 mil by the reasonable disposition of the theodolites.It can meet the test requirements and can remove the uncertainty brought by the stochastic disposition of the theodolite.
