Alerting warning system for fatigued sleeping taxi drivers waiting in rank at night

摘要

The warning system includes a distance sensor fitted at a suitable point at the front of the vehicle especially a taxi cab. So that an unhindered access to the object in front especially a taxi cab to be detected is possible. The system includes a switch and two relays (1, 2) also a voltage converter. The vehicle battery and dynamo are used in conjunction with a sound generator system. This is switched off with the engine running and the dynamo supplying current to the battery and the first relay falling out. With the engine switched off the sound generator is switched on and an acoustic warning signal is given if the vehicle in front moves away at least 1-2 m.
