Pedestrian Crossing Active Multi-Mode Warning System

Abstract

This invention relates to an active multi-mode warning system for pedestrian crossings, comprising a sensing module, a control module, and an warning module. The sensing module senses the stepping behavior of a pedestrian and outputs a first signal. The control module determines whether the first signal satisfies a specific logical condition and outputs an activation signal. The warning module is disposed on at least one side of the pedestrian crossing and receives the activation signal to trigger an warning state.

Claims

1. A pedestrian crossing active multi-mode warning system, comprising: a sensing module disposed on the ground near the approach end of a pedestrian crossing, the sensing module having a left foot stepping area and a right foot stepping area, for sensing the stepping behavior of a pedestrian to output a first signal; a control module electrically connected to the sensing module, for determining whether the first signal meets a specific logic condition to output an activation signal, wherein the specific logic condition includes that the pedestrian's two feet must simultaneously step on the left foot stepping area and the right foot stepping area, and the stepping pressure of the pedestrian's two feet is greater than a threshold range; and an warning module electrically connected to the control module and disposed adjacent to the pedestrian crossing, for receiving the activation signal and triggering a warning state.

2. The pedestrian crossing active multi-mode warning system as described in claim 1, wherein the sensing module is at least one of a piezoelectric sensor, a capacitive sensor, a resistive pressure-sensitive material, or a strain-type force-sensing element.

3. The pedestrian crossing active multi-mode warning system as described in claim 1, wherein the specific logic condition further includes: the stepping pressure of a pedestrian in the left foot stepping area and the right foot stepping area is greater than a weight threshold, and the start signal is output only after a time judgment condition is met.

4. The pedestrian crossing active multi-mode warning system as described in claim 1 further includes a signal processing module, which is disposed between the sensing module and the control module, and the signal processing module is used to amplify, filter or digitize the first signal for the control module to make a judgment.

5. The pedestrian crossing active multi-mode warning system as described in claim 1, wherein the control module includes a settable logic judgment unit for adjusting the trampling pressure threshold, time judgment condition or warning output condition in the specific logic condition according to weather, time period or traffic flow conditions.

6. The pedestrian crossing active multi-mode warning system as described in claim 1, wherein the warning module is disposed on both sides of the pedestrian crossing or above the crossing area.

7. The pedestrian crossing active multi-mode warning system as described in claim 1, wherein the warning module includes at least one of an LED light array, ground recessed lights, flashing arrows, or vehicle side projection light modules.

8. The pedestrian crossing active multi-mode warning system as described in claim 1, wherein the warning state includes at least one of light, sound, or voice prompts.

9. The pedestrian crossing active multi-mode warning system as described in claim 1 further includes a power supply module for supplying power to the sensing module, the control module and the warning module.

10. The pedestrian crossing active multi-mode warning system as described in claim 9, wherein the power module is composed of at least one of mains power, solar panel, lithium battery, or ground-sensor energy recovery module.

11. The pedestrian crossing active multi-mode warning system as described in claim 1 further includes an environmental sensing module for sensing ambient brightness, humidity or traffic density, and providing data to the control module for response adjustment.

12. The pedestrian crossing active multi-mode warning system as described in claim 1 further includes an AI recognition module, which uses image sensing or thermal sensing devices to obtain real-time images to identify pedestrian foot or body features, so that the control module can assist in confirming whether the trampling behavior is triggered by the pedestrian.

13. The pedestrian crossing active multi-mode warning system as described in claim 1 further includes an integrated waterproof structure for encapsulating the sensing module, the control module and the warning module, and the integrated waterproof structure is suitable for ground burial or side mounting.
