为解决目前掘进机定位过程中存在自动化程度低、测量介质易被遮挡等问题,提出了一种基于i GPS的掘进机单站多点分时测量系统,并应用此系统对掘进机偏向位移精度进行研究。根据实际工况,构建单站多点分时测量系统,建立掘进机偏向位移与测量参数的数学模型,根据随机误差建模理论推导出误差传递方程,研究在不同发射站间距、不同测量距离情况下偏向位移误差的变化规律,通过高精度测试系统进行试验验证。
In order to solve the problems of low degree of automation and easily occlusion of measuring medium in the process of heading machine heading, a new type of multi-point time-sharing measuring system based on i GPS for boring machine is proposed. By using this system, research. According to the actual conditions, this paper constructs a single station multi-point time-sharing measurement system and establishes the mathematical model of the heading displacement and measurement parameters. According to the stochastic error modeling theory, the error transfer equation is derived, and the relationship between different transmitting stations and different measuring distances Under the bias displacement error variation, through the high-precision test system for test verification.
