Abstract: Deformation monitoring control network plays an important role in providing monitoring datum and maintaining long-term stability of the datum, but it involves a large number of adjustment mathematical models and stability analysis statistical models, which is far beyond the functional system of conventional adjustment software. The DefDPS integrates complete functional elements of data processing through the whole life cycle of control network, and has the multi-model combined adjustment calculation function for any datum and the multi-model comprehensive analysis function for point stability. The established synergy mechanism between adjustment calculation and stability analysis can efficiently select the stable adjustment datum, which has a practical role in ensuring the long-term stability of datum for deformation monitoring control network. Thus, it's worth popularizing to similar engineering survey control network projects.
