中文摘要：
为保证碾压混凝土坝混凝土浇筑施工质量监控中数据交互的及时进行,提高反馈指导调整施工措施的实时性,设计开发了基于PDA（Personal Digital Assistant）的手持式大坝混凝土施工信息采集系统,实现了碾压混凝土坝仓面混凝土强度与压实度、干密度、湿密度等质量信息的实时数据采集、传输和查询等功能。系统采用三层C/S结构,结合使用GPRS、GPS、多线程等技术,利用Visual C＋＋编程语言,基于Windows Mobile系统平台进行开发。现场使用情况表明,系统的使用减轻了施工现场工作人员的工作量、提高了信息采集的工作效率与施工监控反馈控制的实时性。
英文摘要：
In order to ensure timely proceeding the data interaction in concrete pouring construction quality supervising of RCC dam and to improve the real-time performance of feedback guidance in adjusting the construction measures, a handheld dam concrete constructing information collection system based on PDA is designed and developed. It achieves the functions of real-time data collection, remote transmission and inquiry of RCC dam concrete strength and quality information such as the degree of compaction, dry density, wet density, and so on. Adopting three-layer C/S structure and integrating the technologies of GPRS, GPS and multi-thread, the system is developed with Visual C ＋ ＋ programming language on Windows Mobile platform. By field using, the workload of supervising engineers is reduced, both the efficiency of information collection and the real-time performance of construction supervising and feedback control are improved.
