The invention discloses a projection system based on a pedestrian crossing signal lamp. The projection system based on the pedestrian crossing signal lamp comprises a signal lamp display unit, a detection unit, a control unit, a projection driving unit and a projection unit, wherein the signal lamp display unit is connected with the detection unit, the detection unit is connected with the control unit, the control unit is connected with the projection unit, the signal lamp display unit is used for displaying the states of the signal lamp, the detection unit is used for detecting the signal lamp states of the signal lamp display unit and uses the signal lamp states as the input of the control unit, the control unit generates driving signals used for controlling the projection driving unit according to the signals input by the detection unit, and the projection driving unit controls the projection unit to form projections on the ground where a pedestrian crossing is located according to the driving signals. The projections formed on the pedestrian crossing can achieve a clear warning function, have a good guiding function, improve the safety that pedestrians cross the roads and remind vehicles to slow down.
Description
technical field [0001] The invention relates to a projection system, in particular to a projection system based on pedestrian crosswalk signal lights, and belongs to the technical field of traffic control. Background technique [0002] In traffic control, crosswalk signal light is a kind of traffic light that is often used, and it is convenient for pedestrians to use. Usually, when pedestrians cross the road, they only need to press the green button on the light box pole of the crosswalk signal light, and wait for a few seconds until the indicator light turns green and pedestrians can pass safely. If it is in the countdown state of the red light state, it means that it needs to wait for several seconds before it turns into a green light and pedestrians can pass through. When the button is not pressed, the light is always red. Therefore, the structure is simple and convenient to use, and it is often arranged on crosswalks at intersections to facilitate pedestrians to pass t...
