Description

Automobile safety distance based on GPS is measured and collision avoidance system automatically
Technical field
The present invention relates to a kind of automobile safety distance based on GPS and automatically measure and proximity-warning device, realize the function that the safe distance in vehicle traveling process is measured, judged and report to the police.
Background technology
Automobile has become the main traffic instrument in current life, and its security performance also becomes the focus that people more and more pay close attention to.Automobile when running on expressway because distance between two cars is too near, even if take correct mode of braking still cannot avoid car to car impact under unexpected situation; In dense fog or the lower weather of the such visibility of sand and dust, make driver cannot accurately estimate the safe distance between two cars, thus the generation resulting in an automobile accident.
The outer research for collision avoidance system of Present Domestic is mainly divided into two large classes: a class is that the safe distance that is independent of other equipment is measured and collision avoidance system; Another kind of is with vehicle GPS to satellite emission signal, the signal by two cars judges the distance between two cars.The former has the problems such as install inconvenience and integrated level is low.A kind of basic equipment when vehicle mounted GPS guidance system has nowadays appeared on the scene as car in medium-to-high grade car and being come by universal.The major function of vehicle GPS comprises vehicle tracking merit, traffic path planning and navigation feature, information searching function, traffic command function, emergency aid function in the market, and amusement function.But when running into the vehicle that function GPS of the same race is not installed, also cannot complete safe distance measurement.
Summary of the invention
The object of the invention is for overcome in above-mentioned prior art install inconvenient, integrated level is low and when running into the vehicle that function GPS of the same race is not installed, cannot complete deficiency that safe distance measures provides a kind of and have safe distance and measure the vehicle-mounted GPS apparatus with warning function.This device is measured safe distance with anti-collision warning function and is integrated in GPS above, thereby solves the weak point of above-mentioned two schemes.
Automobile safety distance based on GPS is measured and collision avoidance system automatically, and it comprises transducing part, sensor unit, control module and demonstration and alarm unit, storage unit, and described control module adopts GPS processor.Radio reception module 5 is connected with the input end of GPS processor 6, for receiving satellite signal; GPS processor 6 is controlled transducing part 1 beat signal is passed to signal processing 2, and described signal processing 2 feeds back to GPS processor 6 by spacing information; Sensor unit is by input bus and GPS processor 6 revised theory safe distances; LCD display 9 is connected with GPS processor 6 by output bus, shows current vehicle speed and safe distance; Speech prompting system 8 alarm signal of sounding.
Millimetre-wave radar is installed on the front end of automobile, GPS processor be responsible for safe distance calculating with relatively and by sending the work of signal controlling millimetre-wave radar, phonetic alarm device, LCD display, phonetic alarm device can be to driver's voice message after receiving signal, LCD shows the distance between the current speed of a motor vehicle, two cars, the input of temperature-humidity sensor is for carrying out revising to theoretical safe distance, Calculation of Safety Distance desired parameters deposits in memory module and can be recalled by processor, and radio reception module receiving satellite signal navigates.
Technical scheme of the present invention is utilized the existing speed measuring function of GPS, has avoided repeatedly using vehicle speed sensor, is in structure, to be simplified to have improved measuring accuracy simultaneously.Technical scheme of the present invention is extended on the basis of GPS function, utilize the existing vehicle speed measurement function of GPS, and integrated Cheng Xu ﹑ two spacings that speed meter are counted as to braking distance of being assisted aobvious showing be system ﹑ braking distance and program and the speech prompting system of safe distance comparison, thereby reach the function of range finding and warning.Utilize GPS processor to complete the processing to the control of various piece and data, make whole device there is higher integrated level, enriched the function of GPS.

Embodiment
Below in conjunction with accompanying drawing, for specific embodiments of the invention, be described further.
Automobile safety distance based on GPS is measured and collision avoidance system automatically, on the basis of existing GPS function, is extended.Utilize the existing vehicle speed measurement function of GPS, and integrated by speed meter be counted as theoretical safe distance Cheng Xu ﹑ two spacings aobvious showing be that the theoretical safe distance of system ﹑ is with program and the speech prompting system of distance comparison between actual two cars.
As shown in Figure 1, structure of the present invention comprises: 1. transducing part; 2. signal processing; 3. temperature sensor; 4. humidity sensor; 5. radio reception module; 6.GPS processor; 7. storage unit; 8. speech prompting system; 9.LCD display.
Radio reception module 5 is connected with the input end of GPS processor 6, for receiving satellite signal; GPS processor 6 is controlled transducing part 1 beat signal is passed to signal processing 2, and described signal processing 2 feeds back to GPS processor 6 by spacing information; Sensor unit is by input bus and GPS processor 6 revised theory safe distances; LCD display 9 is connected with GPS processor 6 by output bus, shows current vehicle speed and safe distance; Speech prompting system 8 alarm signal of sounding.
The principle of work of system as shown in Figure 2.In running car, driver presses start button system is carried out to initialization; Radio reception module 5 receives satellite-signal navigation feature and starts; GPS processor 6 can analyze the current speed of a motor vehicle by the satellite-signal receiving and be presented in LCD display 9; The transducing part 1 that GPS processor 6 is controlled millimetre-wave radars sends and receives millimeter wave and beat signal is passed to signal processing 2, and signal processing 2 is changed actual spacing between two cars that obtain after processing to be re-used as input signal and to input to GPS processor 6 by A/D; GPS processor 6 is called in Calculation of Safety Distance desired parameters from storer, by current speed meter, calculate theoretical safe distance and by the parameter of temperature sensor 3 and humidity sensor 4 inputs, theoretical safe distance carried out revising, then this theoretical safe distance is presented on LCD9; The actual spacing of current two car and theoretical safe distance between vehicles that GPS processor 6 calling programs are measured millimetre-wave radar compare, if actual spacing is less than theoretical safe distance between vehicles, drive 8 couples of drivers of speech prompting system to carry out voice message.
