摘　　要：针对测量数据处理实践教学需求,依托教材示例、工程测量控制网数据处理任务,设计开发了室内外一体化的测量平差教学实验平台。实验平台由工程测量控制网、测量平差实验教学软件组成。测量平差实验教学软件分为基础、进阶和创新3个阶段,从易到难渐进式开展实验,包含测量数据读写、精度评价、平差函数模型建立及参数值估计等十余项实验内容,它具有组件、交互、扩展及填充等特征。实践应用表明,该平台为学生提供了工程测绘数据处理应用场景,提高了学生发现问题、分析问题与解决实际问题的能力,加深了学生对误差理论与测量平差原理的理解,缓解了“教师难教、学生难学”的课程教学难题。Aiming at the practical teaching demand of measurement data processing,an indoor and outdoor integrated teaching experiment platform of measurement adjustment is designed and developed based on the object-oriented thought,by relying on the example of teaching materials and the data processing task of engineering measurement control network.The experiment platform is composed of engineering measurement control network and measurement adjustment experiment teaching software.The software is divided into basic,advanced and innovative three stages,and the experiments are carried out progressively from easy to difficult,including more than ten experimental contents such as measurement data reading and writing,accuracy evaluation,adjustment function model establishment and parameter value estimation.The experiment teaching software has the characteristics of component-based,interactive,extended and fill-in.The practical application shows that the platform provides students with application scenarios being close to the production site of surveying and mapping,improves students’ability to discover,analyze and solve practical problems,deepens students’understanding of error theory and measurement adjustment principles,and alleviates the teaching problem of difficult for teachers to teach and students to learn.teach and students to learn.
