基于数字量分层定义解析的实时物理量显示

摘要

In the past, the digital datas in the analysis of Missile Telemetry datas that been whole form display by the serial datas packets. The real-time state of the test parameters of missile weapon is not reflected,so the real time physical datas display based on the hierarchical definition of digital datas is put forward. Digital datas has been real-time shunt and unpack by embedded computer system, and the important feature of the digital datas be return to actual engineering physical datas and real-time display.Through multiple out test validation and comparison results of data information by different test equipment, the test data show that the method is stable and reliable, and it improves the accuracy and rapidity of fault diagnosis of missile weapon test.%针对以往弹箭遥测数据处理中数字量以串行数据包整体形式显示,不能反映出弹箭武器各测试参数的实时工作状态,提出了基于数字量分层定义解析的实时物理量显示.该方法依据数字量的分层定义,利用嵌入式计算机系统对数字量进行实时分路、解包,选择性的将数字量中的重要特征量还原成实际工程物理量并实时显示.多次外场的弹箭遥测试验验证及不同测试设备数据信息的比对结果表明,该方法测试数据稳定、可靠,提高了弹箭武器试验阶段故障诊断的快速性和准确性.
