Stray Current Development Of The Automatic Detection System

Along with the development of metro, the prevention and cure question of the metro stray current is brought into schedule gradually. This text summes up the production, danger and present shelter measure of the metro stray current first, later introduces the main research content of the subject and it's laboratory model, finally introduces the automatic detection system of metro stray current designed by myself and used in laboratory in detail.This text is organized according to the step of the development of the system, including system analysis ,system architecture design , system implemention and system test. It gives a detail analysis of each units, especially analyzes the communication between the computer and the apparatus , the synchronization technology, software smoothing and the time collection technology in the system, also gives the implementation method.After debugging this system and analyzing the data, this system's linearity is very good, reached 99%. So this system can meet the need of the scientific research work. This system has a very convenient user interface, can gather data well and truly. Using this system, user can save a lot of time and money in the research.
