Abstract

A velocity detector includes a GPS receiver, a velocity record arrangement, a velocity signal input device, a warning device, and a release button. Thus, when the travel velocity of the automobile is greater than the uppermost velocity limit or smaller than the lowermost velocity limit stored in the memory of the velocity record arrangement, the output port of the velocity record arrangement immediately outputs a signal to the warning device so as to emit a warning sound or warning light to remind the user, thereby providing a warning effect to the user, so as to protect the driver'"'"'s safety during movement of the automobile.

Claims

1. A velocity detector, comprising:

a GPS (Global Positioning System) receiver having an output port;

a velocity record arrangement connected to the output port of the GPS receiver and provided with a memory and an output port;

a velocity signal input device connected to the GPS receiver; and

a warning device connected to the output port of the velocity record arrangement.

2. The velocity detector in accordance with claim 1, wherein the GPS receiver is mounted on an automobile.

3. The velocity detector in accordance with claim 2, wherein when the automobile is traveled at different velocities, the GPS receiver produces different velocity signals, and the velocity signals are transmitted outward through the output port of the GPS receiver.

4. The velocity detector in accordance with claim 3, wherein the velocity record arrangement receives the velocity signals from the output port of the GPS receiver.

5. The velocity detector in accordance with claim 3, wherein the memory of the velocity record arrangement stores the velocity signals from the output port of the GPS receiver.

6. The velocity detector in accordance with claim 1, wherein the velocity signal input device inputs a predetermined velocity value into the GPS receiver.

7. The velocity detector in accordance with claim 1, wherein the warning device is a buzzer.

8. The velocity detector in accordance with claim 1, wherein the warning device is a warning lamp.

9. The velocity detector in accordance with claim 1, further comprising a release button connected to the velocity record arrangement so as to release a velocity value recorded in the velocity record arrangement when the release button is pressed by a user, so that the user can reset the predetermined velocity value.
