Conditioning conversion circuit for airborne time sequence and initiating explosive device test

Abstract

The invention discloses a conditioning conversion circuit for airborne time sequence and initiating explosive device test and belongs to the field of missile test control. The circuit comprises a multipath twistor switch SK1, a current-limiting resistor R1, a current-limiting resistor R2, a photoelectric coupler U1, a relay K1 and a relay K2, wherein the twistor switch SK1 is a gating device, during the time sequence test, an SK1-1 gear is conducted, and input time sequence signals are subjected to conditioning conversion; and during the initiating explosive device resistance test, an SK1-2 gear is conducted, and input initiating explosive device signals are converted. Compared with the prior art, the conditioning conversion circuit has the beneficial effects that the development cost is saved, the preparation workload before the test is reduced, and the maneuverability of the system is improved; the design thoughts of centralized planning and time sharing application are adopted, the development resource is more centralized, the real-time state monitoring and management is convenient, and the reliable time-sharing completion of conditioning conversion of different signals can be ensured; and the problem of an interface circuit between an airborne electric system and test control equipment is solved, and the effectiveness and the reliability of collected signals are ensured.

Description

technical field [0001] The invention belongs to the field of missile test control, and in particular relates to a conditioning conversion circuit for missile loading timing and explosive product testing. Background technique [0002] The timing control system is an important part of the missile control system. Its function is to give the detonation signals of various explosive products and the conversion or time control signals required by other circuits in accordance with the required time sequence, so as to realize the ignition, shutdown and missile control of the engine. Separation of parts. The failure of the time control system or pyrotechnics will affect the accuracy of the orbiting at a light level. In severe cases, it will directly cause the failure of the entire missile launch test, and even endanger the safety of the launch site and the test personnel. Therefore, before the flight test, the missile must be ignited. The timing signal and the resistance value of the...
