This paper introduces a kind of contact train obstacles and derailment detection device. It is composed of detection device and electric box. The energy produced by collision between obstacles and detection device and the train derailment is converted to electrical signal which can be measured, then it could control emergency braking. It can minimize the impact of foreign matter on vehicle safety or operation order after entering the vehicle limit. This system uses CPLD as the control core and adopts double redundancy design that improved the reliability of the device. It provides guarantee for train running safety and has good application prospect.
