Through the connection with a dedicated remote control box, NM7000B ILS equipment can transmit ILS equipment running real-time status to the control room. However,the remote control box can only produce very low sound,which often can＇t attract the attention of monitoring personnel, especially when they are exhausted at night, which is likely to cause accidents. This paper designed a set of the practical mobile terminal of the warning system to make up for its defects. This system is composed of single-chip microcomputer control module,TC35 module of mobile end,relay module,and remote control box. When the ILS equipment encounters a failure,it can send a message or call timely and accurately to remind the monitoring personnel of the failure so as to reduce the landing accidents of aircrafts.
