| titleOfInvention | Portable CNI system detection handheld terminal |
| abstract | The invention discloses a portable handheld terminal for detecting a CNI system, and aims to provide a handheld terminal which is convenient to carry, facilitates the outfield to quickly detect and maintain various functions of an airborne CNI system, and timely eliminates faults. The invention is realized by the following technical scheme: the digital signal processing unit integrates various functions of CNI communication, navigation and identification based on a radio frequency channel unit, a security machine, an audio processing circuit unit and a display control unit which are integrated in the handheld terminal equipment, receives voice communication, data communication, radio navigation, identification and navigation management response signals from the radio frequency channel unit through a standard interface multi-channel, and forms complete hardware channel link resources from the antenna unit, the radio frequency channel unit to the digital signal processing unit; the radio frequency channel unit receives and transmits radio frequency signals of different frequency bands by means of the antenna unit, and signal interaction between the CNI system and the digital signal processing unit is achieved; and verifying the functions of the onboard equipment of the CNI system. |
