This article from the infrared detection system Hotbox formed during the historical development of the concept in the use of railways with heavy, high-speed development requires the presence of non-adaptive, hysteresis start line for the Datong-Qinhuangdao railway construction in our country overloaded special status, technical characteristics and transportation needs, noting that improving vehicle Hotbox intelligent detection system (referred THDS) hot shaft forecast accuracy of the urgency and necessity. Thesis infrared temperature measurement systems theory and the theoretical basis THDS working principle, the use of a large number of on-site use of data, the typical case for example, describes the impact of the use of the Datong-Qinhuangdao line THDS level of the main factors, from the system works on a detailed analysis and demonstration of the problems have The fundamental reasons to take a breakthrough system architecture, design, build and improve innovative thermal axis discriminant mathematical model methods to achieve the level of use of the Datong-Qinhuangdao line THDS significantly improved. Made full use of the vehicle while running security early warning system (referred to as \This thesis mainly the following aspects: First, C76, C80-type hot axle heavy vehicles to analyze the causes of false positives, demonstration, proposed sliding \method; Second is the cause false positives hot hot shaft seals cause analysis, feasibility studies, suggest improvements bearing sealing device and the \Empty forecast more heavy vehicle axle causes thermal analysis, feasibility studies, proposed distinction between empty and loaded cars revision tracking hot shaft discriminant model solution; Fourth, seasonal changes in ambient temperature forecasts hot shaft impact analysis of the causes , demonstration, proposed to increase the \density) method to be controlled; six is ??through the \perspective, the use of comprehensive prevention concept, the vehicle security system as a whole to play advantage.
