Description
Roads across free wild landscape pose a permanent danger of accidents in which vehicles collide with wild-life animals. In most cases animals are aware of the sound and visibility of approaching cars. In rare situations, however, either at dawn/sunset or rare traffic, or at specific topologic situations, collisions happen between vehicles and animals. We propose a sensor/actuator system that prevents these collisions by warning animals. This system consists of active electronic components and is operated by solar power. Tests with the previous generation of this device showed a reduction of accidents by 89% and under certain conditions by more than 95%. The system consists of devices that can operate alone or as a group. The device is operated by a microcontroller, it contains optical/acoustic sensors and actuators, a wireless communication facility, and is supported by a power harvesting/storage/control system. One device is 18 cm in height, 9 cm in width and 7 cm in depth, weighs about 400 g and it is mounted on any guide post in the street. One device detects approaching vehicles either by their sound (microphone sensor) or head light (solar cell used as light sensor) and emits a tone of about 4 kHz directing off the street warning the animals. A LED flash light gives an additional optical warning. The tone makes animals observe their environment carefully and keeps them staying several seconds preventing them crossing the street at the same time when a vehicle comes by. A group of nearby devices is connected wireless. They are placed about 30-50 m apart. One can stand in the street and another one 50 m away upwards or downwards remotely from the street for keeping aisles and curved areas safe.| Period | 7 Oct 2018 |
