基于PC104的某型航空发动机排气温度测试系统

Design of exhaust temperature test system of a certain type aeroengine based on PC104

为了解决某型航空发动机排气温度无法地面实时监控的问题,研制了排气温度测量系统。该系统利用PC104嵌入式工业计算机作为其核心控制器,设计了排气温度检测电路和冷端温度补偿电路,编写了数据采集、处理和显示程序。通过该测量系统,可以使地面保障人员在发动机试车过程中实时监控发动机排气温度,确保其对于发动机工作状况的正确判断。

An exhaust temperature test system is developed for resolving the problem that the exhaust temperature of a certain type aeroengine can not be real time monitored. The exhaust temperature test and temperature compensate circuit are designed and data collecting, processing and displaying program are written in this system which utilizes PC104 built-in industry computer as its core controller. The exhaust temperature of aeroengine can be real time monitored during test-drive by ground guarantee staff, which can help them to judge the condition of the aeroengine.
