Online data processing method for missile fire control system

Abstract

The invention discloses an online data processing method for a missile fire control system, which can reliably and completely process all data in real time and has high robustness. The method has lowrequirements on hardware and software environments and is low in cost. Even if the front-end device is not provided with an operating system or the provided operating system can only support a single-thread program, the method can be realized, and the method is relatively simple. The front-end method is essentially a single-thread algorithm based on time slice rotation driving, processing can be accurately and reliably completed in real time even if a plurality of fire control tasks exist, and the rear-end method can completely, reliably and timely process all data even under the condition that the front end sends massive high-speed data at a time or the rear end has graphic operation or display. The method has high robustness.

Description

technical field [0001] The invention belongs to the technical field of missile fire control system design, and in particular relates to an online data processing method of the missile fire control system. Background technique [0002] For a missile fire control system, it is very important to be able to process various data of the missile fire control system online in a real-time, accurate, reliable and complete manner. Generally, in view of the safety of the fire control system operators, the missile fire control system generally adopts a front-end and rear-end distributed layout. ) to the back-end fire control station, and the fire control station performs data processing (calculation, judgment, display and storage, etc.) in real time. [0003] Generally, when designing a missile fire control system, in order to be able to perform fire control tasks in real time and process a huge variety of data, the front-end and back-end data processing methods are more commonly used: ...

AI Technical Summary

Problems solved by technology

[0005] 1) The development cost of the front-end system is too high. A real-time system (such as VxWorks) and its corresponding development environment need at least about 200,000 RMB, and the system development is difficult, with high learning costs and large investment; in addition, real-time operating system tasks Scheduling is complex, fire control data processing and timing control are complex (fire control model calculation, launch timing control, etc.), and multi-task scheduling must be used, which is lower in reliability, synchronization, and timing control accuracy than single-threaded;

[0006] 2) The robustness of the back-end online data processing method is average. When a large amount of high-speed data (such as ignition current data, model calculation, timing signal, navigation information, etc.) is sent or the back-end fire control console has graphic operations (such as animation, video Image display), often due to too late to process, resulting in data loss or a large delay in the system (stuck), or even crash (unexpected exit or crash)
