Study on management information system of railway line clearance detection based on noncontact measurement technique

The railway line clearance detection is an important guarantee for the security of rail traffic. This paper studies a line clearance detection device based on noncontact measurement. On base of the system solution introduction, this paper emphasized on description of the software features and the design of the management information system. Also, the exceeding point real time judgment algorithm is presented, and the related experiment is completed. As shown in the experiment, the collection of the complete profile data, the judgment of the exceeding point and the management function of the data can precisely and timely complete.
