Abstract

The present invention provides a warning device in which a radar module is combined with electronic control technology to accurately detect the speed and distance of objects in the environment and thus provide a dynamic warning (flashing or buzzing). The radar module is housed in an electronic component box and maintains a specific distance from the ground to avoid interference caused by ground echoes and to reduce noise in the acquired data point cloud information. The control system extracts the position and relative speed of a target object from the data point cloud information, filters out the approaching moving points, and then uses these moving points to determine the relative distance and direction of the target object. Depending on the approach of the target object, the flashing frequency of the warning lights is dynamically adjusted, or the buzzer is activated.
