Embodiment Construction

[0011] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0012] The GPS-based automatic safety distance measurement and collision avoidance device for automobiles is an extension of the existing GPS functions. Use GPS's existing vehicle speed measurement function, and integrate the program that calculates the vehicle speed into a theoretical safe distance, a distance display system between two vehicles, a program that compares the theoretical safe distance and the actual distance between two vehicles, and a voice prompt system.

[0013] Such as figure 1 As shown, the structure of the present invention includes: 1. Sensing part; 2. Signal processing part; 3. Temperature sensor; 4. Humidity sensor; 5. Radio receiving module; 6. GPS processor; 7. Storage unit; 8. Voice prompt system; 9. LCD display.

[0014] The radio receiving module 5 is connected to the input terminal of the GPS processor 6 for receiving satellite s...

Abstract

The invention discloses an automobile safe distance automatic measuring and anti-collision device based on a GPS. The device comprises a sensing part, a sensor unit, a control unit and a display and warning unit, wherein a GPS processor is adopted in the control unit, a radio receiving module (5) receives a satellite signal and is connected with the input end of the GPS processor (6), the GPS processor (6) controls the sensing part (1) to transmit a beat frequency signal to a signal processing part (2), the signal processing part (2) feeds vehicle distance information to the GPS processor (6), the sensor unit and the GPS processor (6) modify the theoretical safe distance through an input bus, an LED displayer (9) is connected with the GPS processor (6) through an output bus to display current vehicle speed and the safe distance, and a voice prompt system (8) sends out a sound warning signal.

Description

Technical field [0001] The invention relates to a GPS-based automobile safety distance automatic measurement and anti-collision alarm device, which realizes the functions of safe distance measurement, judgment and alarm in the process of automobile driving. Background technique [0002] Automobile has become the main means of transportation in today's life, and its safety performance has become the focus of more and more attention. When a car is driving on a highway, the distance between the two cars is too close. In an unexpected situation, even if the correct braking method is adopted, the two cars cannot avoid a collision; in heavy fog or sand and dust, the visibility is relatively low. In this way, the driver cannot accurately estimate the safe distance between the two vehicles, resulting in a car accident. [0003] The current research on collision avoidance systems at home and abroad is mainly divided into two categories: one is the safety distance measurement and collision ...
