Design of Railway Axle Testing System
Abstract
Axle detection system can determine whether track segments occupy or leisure. It has a wide range of use and it is reliable. With the development of the detection system, it has the important significance of the research. It can protect transportation safety and efficiency.
At present, the outdoor equipment system has to medium and long term monitoring in harsh environment. It is necessary to select excellent sensors.
It must be give full consideration to the safety and reliability of the whole system in the process of the design of the whole system. Based on sensors and other equipment performance requirements to choose the appropriate sensor is applied to the design. In this paper, the design uses the smart sensor, it can deal with signal in advance to improve the system performance. It uses selecting 2 from 2 logic and dynamic drive safe input or output circuit in the aspect of hardware design. It can improve the system’s reliability and stability.
