Code controlled power supply circuit for missile launch control system

Abstract

The invention discloses a code controlled power supply circuit for a missile launch control system. The circuit comprises an electromagnetic relay K1, an eight-channel Darlington tube array U1, an eight-input NAND gate U3 and sixth-NOT gates U2, U4, U5, U6 and U7. The circuit disclosed by the invention is controlled by working logics, wherein the working logics is operated by a master control CPUof the missile launch control system after the master control CPU is powered on. Through matching with peripheral equipment: a ground power supply, a ground auxiliary power supply and a 5V power supply converter, the missile launch control system is effectively and reliably guaranteed to be connected with the ground power supply circuit strictly according to a working process time sequence when the missile launch control system works.

Description

technical field [0001] The invention belongs to the technical field of missile launch control, and in particular relates to a coding control power supply circuit for a launch control system. Background technique [0002] The missile launch control system is referred to as the launch control system. Its task is to control the launch preparation and launch process of the missile to ensure the normal and smooth launch of the missile. Rely on. During the pre-launch detection process, the launch control system needs to receive orders from the command and monitoring system to complete various pre-launch inspections of the bombs and implement the ignition and launch control of the bombs. The basis of all work is that the launch control system supplies the working power to the bomb-loading electrical equipment normally and accurately according to the work process. Therefore, when designing the launch control system circuit, the reliability and safety of the power supply control ci...

Problems solved by technology

However, the application of this method has certain potential safety hazards, that is, after the power-on of the transmission and control system itself, there will be a state initialization process. At this stage, the DO output of the main control CPU of the system is not controlled by the software, and all of them are in a floating state. , so all the on / off circuits controlled by the DO output of the subsequent stage are all in the on state, resulting in the short period of time during which the state of the transmission control system is initialized. The ground power supply circuit of the stage will be connected, which may have a certain impact on the normal operation of the launch control system and the launch system
