Warning device and street light system
First Claim
1. A warning device, comprising:
- a sensor which is attachable to a supporting member and measures a distance, the supporting member being fixedly installed; and
a notifier which performs notification using predetermined output, wherein;
the sensor measures at least one of sensor-object distances and a moving object distance, the sensor-object distances being distances between the sensor and each of at least two moving objects which are approaching to each other, the moving object distance being a distance between the at least two moving objects which are approaching to each other,the notifier performs the notification by varying a manner of the predetermined output according to the at least one of the sensor-object distances and the moving object distance which are measured by the sensor,the at least two moving objects include a short-distance object and a long-distance object, the short-distance object being located at a position closer to the sensor than the long-distance object,the sensor further detects an acceleration of the long-distance object,the notifier further varies the manner of the predetermined output when the sensor detect an abrupt acceleration of the long-distance object,the supporting member is fixed in a state in which a portion of the supporting member is embedded in a ground, andthe long-distance object and the short-distance object are moving in a same direction.

Abstract
A warning device includes: a sensor which is attachable to a supporting member and measures a distance, the supporting member being fixedly installed; and a notifier which performs notification using predetermined output. The sensor measures at least one of sensor-object distances and a moving object distance, the sensor-object distances being distances between the sensor and each of at least two moving objects which are approaching to each other, the moving object distance being a distance between the at least two moving objects which are approaching to each other, and the notifier performs the notification by varying a manner of the predetermined output according to the at least one of the sensor object distances and the moving object distance which are measured by the sensor.
