Abstract

The invention discloses an obstacle avoidance method and an obstacle avoidance system. The method comprises the steps in which, an optical receiver receives an optical signal of a measured target on a travelling track of a rail train and transmits the received optical signal to a visible light sensor; the visible light sensor generates an optical image of the measured target based on the received optical signal and transmits the generated optical image to a PLC; and the PLC takes measures of obstacle avoidance based on the received optical image. The invention solves the technical problem that an obstacle avoidance method is prone to mistakes by way of artificial viewing in the related art, and the accuracy and timeliness of obstacle detection are improved.

Description

technical field [0001] The invention relates to the field of distance measurement, in particular to an obstacle avoidance method and an obstacle avoidance system. Background technique [0002] In the process of train operation, it is inevitable to run into obstacles, and at this moment, trains are needed to perform shunting operations. In the related technology, during the train shunting operation, the manual lookout method is generally adopted. However, this artificial lookout method will be greatly affected by the environment and the person itself, and manual lookout errors are prone to occur. In this case Therefore, it is likely that the running train will not find the obstacles on the curve in time, and will slow down and brake, which will lead to accidents such as vehicles hitting foreign objects or rear-end collisions when the line is abnormal. [0003] Aiming at the problem that the obstacle avoidance method in the above-mentioned related technology adopts the manual...
