Abstract


The rapid development of the field bus for the flight data acquisition and processing system development provides a good opportunity, but also poses a challenge to China's current low level of flight data testing technology, field bus technology used in flight data acquisition system has become imperative. The flight data acquisition system using field bus technology, data acquisition can be mounted on a bus, significantly improves the acquisition and processing capabilities, enhanced flexibility, which is the development trend of the flight data test system. The subject is the flight data acquisition and processing system for fieldbus technology to conduct research. LonWorks network control technology is developed rapidly in recent years, the field bus control technology, widely used in industry, building, transport, energy and other areas of automation. Set of computer, networking and control in one integrated ISO / OSI seven layer protocol, communications and control functions at the same time, it provides 34 kinds of common I / O control object, flexible networking, openness, at the same time already installed on some aircraft of foreign products based on LonWorks technology development. All this shows that it can be well applied to the flight data acquisition and processing system. Traditional data acquisition system uses a general microcontroller has to meet the requirements, the vast majority of occasions, but the microcontroller poor math, signal processing for more complex flight data acquisition and processing field, appeared to be inadequate. Compared to the average microcontroller dedicated to the processing of complex mathematical algorithms and complex control DSP chip in faster system speed and strong math. Therefore, this paper presents a combination of DSP and microcontroller advantages of data acquisition and processing system implementations. The system uses a multi-processor combination, networking topology, DSP implementation with a PC data management capabilities, based on Lonworks group network communication microcontroller as the core multi-channel synchronous acquisition of field data, to achieve multi-channel field parameters collection, transmission and processing. The article describes in detail the implementation of the various parts of the data acquisition and processing system, and shows a flowchart of a part of the data processing and software algorithms. The system uses a modular design, easy installation and maintenance, and to further reduce the size and cost of existing the flight parameters monitoring and control systems.
