分布式火控系统实时通信的设计实现

实时可靠的通信系统是实现分布式火控的关键。介绍了在一个小型实时通信系统的设计中,为保证通信的实时性采取了节拍控制、数据分级、重发限制等方法,为提高通信可靠性采用了断路重组技术、差错控制和冗余技术,软件采用了面向对象分层次模块化设计的方法,提高了可维性和可扩展性。通过这些措施,实现了5km距离内数据和语音的多点实时传输,误码率小于10-6,通信时延小于150ms,满足了分布式火控系统的要求。

Implementation of Real-time Communication in a Distributed Antiaircraft Artillery System

A reliable real-time communication is key technology to realized a distributed artillery control system.The authors introduce beating control data grading and retransmission control in the design of small-sized communication system for ensure real-time communication,adopt reconstruction limitation of broken ciruit,error control and redundancy technique for ensure the reliability of communication.The software uses oriented-object hierarchical moduar design to raise the maintenability and extensibility.Through these methods,real-time data and soud multicasting can be realized within five kilometers distance.Its error rate is less than 10~(-6),and communication delay is less than 150ms.Demands of distributing antiaircraft artillery system are met.
