【摘要】：两支路自动循环调配系统广泛应用于空调等电气系统的温、湿度自动调节,即当温、湿度等控制参数达到某一设定阈值时,调配系统自动切换至另一支路进行工作以达到参数调控的目的。针对部件寿命服从指数分布的情况,分析了转换开关失效对系统可靠性的影响模式,构建了两支路自动循环调配系统的物理模型,应用Markov链理论求出冷贮备条件下系统不同状态间的转移概率及其转移率矩阵,再通过Laplace变换得到在不同条件下两支路自动调配冷贮备系统的可靠性预测公式。空调系统的应用研究验证了可靠性预测模型的有效性。
[Abstract]:The automatic circulation and distribution system of two branches is widely used in the automatic adjustment of temperature and humidity in air conditioning and other electrical systems, that is, when the control parameters such as temperature and humidity reach a certain set threshold, The dispatching system automatically switches to another branch to work in order to achieve the purpose of parameter control. In view of the exponential distribution of component service life, the influence mode of switch failure on the reliability of the system is analyzed. The physical model of automatic circulation distribution system with two branches is constructed, and the transfer probability and transfer rate matrix between different states of the system under cold storage condition are obtained by using Markov chain theory. Then the reliability prediction formula of the cold reserve system is obtained by Laplace transformation under different conditions, and the validity of the reliability prediction model is verified by the application of the air conditioning system.
