Signal detector

Abstract

The invention discloses a signal detector which comprises a signal detecting box and a detecting cable. The signal detecting box is internally provided with a controller, a wireless communication module, a display screen, a data acquisition module, a signal conditioning circuit, a load simulating module, a testing interface, a relay module and an RS485 communication module. The signal detector according to the invention simulates a missile hanging-up state through the load simulating module, thereby realizing normal operation of an on-plane weapon control system and an on-plane missile launching device, performing simulation detection on a crosslinking signal between the missile and the on-plane weapon control system without mounting a training missile, accurately detecting a fault reason,and preventing missile damage caused by misjudgment. Furthermore the signal conditioning circuit is used for performing signal conditioning on four DC power supply signals supplied to the missile byan on-plane power supply and an indicating signal that is transmitted from the on-plane weapon control system to the missile, thereby ensuring identifiability of the data acquisition module, improvingsignal acquisition accuracy and further ensuring high accuracy of the simulating detecting result.

Description

technical field [0001] The invention relates to the technical field of detection of cross-linking signals between missiles and airborne fire control systems, in particular to a signal detector. Background technique [0002] At present, the maintenance personnel need to mount training bombs for the inspection and maintenance of the aircraft fire control system and missile launcher, and judge the fire control system and missile launcher by observing the deflection and rotation of the training missile seeker mounted on the aircraft with human eyes performance is normal. [0003] However, this kind of discrimination method has a high misjudgment rate, and some airborne signals cannot be judged by human eyes at all. If the missile is not working properly when it is on-hook, the crew cannot distinguish whether the missile is not working properly caused by the failure of the aircraft's fire control system or the failure of the missile itself, which is very likely to cause damage t...
