Abstract:
1. A collision prevention automatic warning system, comprising: a controller, adapted for determining that a collision has occurred; an input circuit connected to said controller, having at least one parallel-connected collision sensor; an output circuit having, parallel-connected, a light-emitter, and a sound-emitter; and a power circuit having an electric battery power supply and a standby battery supply, connected in parallel by an isolation diode; wherein, the mutually parallel connected sensors are linked to one end of the controller, and the light-emitter and the sound-emitter are linked to another end of the controller; the control circuit utilizes electric power supplied by the electric battery power supply, and when the electric battery power supply loses efficacy, the standby battery supply is able to provide the required electric power; further wherein, when a vehicle collision occurs, the sensors detects the collision occurrence and transmit a signal to the controller, whereupon the controller notifies the light-emitter and the sound-emitter, which thereupon emit a bright light and a loud sound respectively.
