| 摘 要： | 为防止水电工程大型施工设备之间的碰撞现象,基于GPS、无线网络通信、信号采集、嵌入式系统等技术,构建了不同于传统系统的防碰撞预警系统,该系统可以准确预测设备间的碰撞,为大坝施工提供了可靠的安全保障.提出了一种用于施工设备正常制动的安全距离计算模型,考虑到其主要影响因素的随机性,采用蒙特卡罗法及遗传算法对其进行可靠度分析,数值分析及现场实验表明,该模型具有极高的可靠性.

| Abstract: | Based on the technologies such as GPS,wireless network,signal collection,embedded system,a novel collision early warning system is presented for avoiding collision phenomena between large-scale construction equipments in hydropower projects.It can forecast exactly collision between equipments so as to provide a reliable safeguard for dam construction.And a safety distance model for normal brake of equipments is also proposed.Due to the randomness of its main factors,the model reliability is analyzed by using Monte Carlo method and genetic algorithm.The results indicate that the model has high reliability. |
