Abstract：The article introduces the warming system when a traffic accident caused by
Rear-end collision between two cars . The system includes the collecting information
unit , the central controlling unit, the alarm circuit and the display unit etc. First, the
car running states are collected by four sensors, Then, All of the collecting
information is analyzed and judged by a single chip microcomputer, forecasting and
judging will be complicated, If there is a hidden trouble of rear-end collision
accident, an alarm will be given ,In addition, display unit is designed.
Key words：sensor collecting information rear-end collision alarming system
