- 摘要:
- 航天产品多余物控制是保证和提高航天型号研制质量的一项重要内容。现有的航天产品多余物控制方法和装置普遍存在检测效率低、精度低及价格高等问题。针对上述现象,设计了一种基于STM32微处理器的液体火箭发动机管路的多余物自动检测及清洗系统。系统由超声波管路清洗装置、多余物检测装置、上位机和信号采集装置组成。基于STM32微处理器的控制功能,能够实现对发动机管路多余物的自动清洗和检测,并能够实现液位信息和清洗结果的实时采集、传输、显示和存储,并可根据检定结果触发清洗装置进行二次清洗。同时,系统能在自动清洗和手动清洗之间进行切换。旨在解决液体火箭发动机管路多余物的检测和排除的问题,并有效地提高多余物检测和控制的效率和可靠性。
- Abstract:
- The control of foreign object debris is an essential part in the design and testing of aerospace products. However, since efficiency and accuracy of current foreign object debris detecting methods are low, a STM32-based system for detecting and cleaning the foreign object debris in pipelines of liquid rocket engine was designed. It is composed of ultrasonic pipe cleaning device, foreign object debris detecting device, signal acquisition device and industrial computer. With the control function of STM32, the system can realize automatic detection and cleaning of the foreign object debris in pipeline of liquid rocket engine, real-time acquisition, transmission, display and storage of liquid level information and cleaning effect. In addition, re-cleaning procedure can be started according to the detection result. The system can be switched between automatic cleaning and manual cleaning, which can
