【摘要】 航空发动机状态监测系统是发动机地面试车的重要组成部分，由于状态监测系统中需要采集的参数很多，定期手工检测每一条数字通道和模拟通道的完好性和通道特性是一项工作量很大的工程；利用参数估计和假设检验的方法，设计了一套传感器通道标定系统，用以完成检测通道的特性和完好性；测试结果表明，该系统具有测试精度高、可靠性好、易操作等特点；此外也可推广应用于航空发动机之外的其它状态监测系统。更多还原

【Abstract】 The condition detecting system is an important part for an aero-engine’s ground experiments. With many parameters to be collected, it is a very large project to detect if every digital channel and analog channel is perfect in the system. A sensor channels detecting system is designed by using the knowledge of parameter estimation and hypothesis test to complete its functions. The result shows that the system has high precision and good reliability and it is easy to run. Furthermore, the system can be also used in other condition detecting system.更多还原
