摘　　要：阐述了门禁系统的结构和功能、门禁系统电源稳定性指标。在此基础之上,进行了门禁系统电源稳定性分析,并进行了门禁系统电源稳定性测试,总结了系统电源稳定性设计方法。并将上述开关电源稳定性设计方法和结论应用到了门禁系统开关电源的设计中,经过多次测试,系统电源稳定性得到很大程度提高。The structure and function of access control systems, and its power stability indicators were described. On this basis, the power stability of access control system was analyzed, its power stability was tested, and its stability design was summed up. The above design method and the conclusion were applied to the design of switching power of the access control system. For repetitious tests, the stability of the system power was largely improved.
