目前国内民航飞机已放开机上PED（Portable Electronic Device,便携式电子设备）开机、上网限制,该举措给乘客带来更优质的服务体验的同时,对机载航空电子设备的运行也存在一定的潜在风险,为了更好地研究PED辐射对航空电子设备的电磁干扰威胁,提出了一种PED模拟器的设计方法,该模拟器可模拟客舱乘客真实使用手机、PAD等电子设备的场景,可生成与之相同的辐射信号,同时可实现可集中式控制管理,无须人员频繁的操作,更便于开展PED干扰测试试验。该模拟器已在某国产民航客机开展试验测试,通过与真实PED干扰数据对比,该模拟器生成的干扰与真实信号基本一致,因此该成果可广泛应用于民航客机的PED干扰测试场景。

At present, domestic civil aviation aircraft has l implemented PED (Portable Electronic Device) startup and internet access restrictions. While this measure provides passengers with a better service experience, there are also potential risks to the operation of onboard aviation electronic devices. In order to better study the electromagnetic interference threat of PED radiation to aviation electronic devices, a design method for a PED simulator is proposed. This simulator can simulate the real scenarios of cabin passengers using electronic devices such as mobile phones and PADs, generate radiation signals identical to those of actual devices, and realize centralized control and management. It eliminates the need for frequent manual operations, making it more convenient to carry out PED interference testing experiments. The simulator has been tested on a domestic civil aviation aircraft. By comparing with the interference data of real PEDs, it is found that the interference generated by the simulator is basically consistent with the real signals. Therefore, this achievement can be widely applied to PED interference testing scenarios of civil aviation aircraft.
