摘要
无线电监测表明,手机与基站通信产生的干扰信号影响射电天文观测数据,为了抑制射频干扰,天文学家提出屏蔽站内电子设备、设置无线电宁静区等管理办法,其中的手机信号因易移动、基数大而难以监测和管理.然而,开启手机的飞行模式或关机可以降低射频干扰.基于此设计和开发了一款基于安卓(Android)系统的手机干扰管理应用程序,采用定位技术自动判别手机是否处于无线电宁静区,以提醒用户管理手机,并记录用户在宁静区内的操作.测试结果表明,当用户处于无线电宁静区时,应用程序能主动提醒用户开启飞行模式或关机,有效降低手机信号对天文观测数据的影响.
Radio monitoring shows that interference signals generated by mobile communication with base stations may affect radio astronomical observation.Astronomers proposed radio management rules to mitigate radio frequency interference,such as shielding electronic equipment in the station and setting up radio quiet area.However,these rules are difficult to carry out as a result of the high mobility and large quantity of the devices,while setting the mobile on airplane mode or turning off the mobile can reduce the generation of signals.On the basis of airplane mode or shutdown,this paper designs and develops a mobile interference management APP based on Android.The APP can judge whether the mobile is in the radio quiet zone by using mobile positioning technology,and reminds the user to manage his/her mobile,and saves user′s operation record in the radio quiet zone.Through analyzing the results of experiments,once a user enters the radio quiet zone,the APP can remind the user to put the mobile on airplane mode or turn off,which could reduce the influence of signals on astronomical observation.
