Description

A kind of vehicle-mounted early warning, warning and distress system
Technical field
The utility model belongs to traffic safety technology field, is specifically related to a kind of vehicle-mounted early warning, warning and distress system.
Background technology
According to statistics, China's automobile pollution is less than the whole world 2%, but the average annual toll on traffic of China is about 100,000 people, accounts for 20% of global traffic death by accident sum.
For many years, because China's automobile pollution increases swift and violent, so annual toll on traffic always constantly creates new peak.According to the statistical figure of the Ministry of Public Security, 2002, China ten thousand car death toll was 13.7 people; And according to Nissan Motor technician introduction, this numeral is more than 10 times of Japan.At present, China's vehicle guaranteeding organic quantity reaches 2.64 hundred million, wherein 1.54 hundred million, automobile; Vehicle driver breaks through 300,000,000 people, and wherein motorist is more than 2.46 hundred million people.According to hygiene department's statistics, the death toll caused because of traffic hazard by 2012 has reached 160,000 people.
Chinese transportation death tolls remains high, and reason is numerous.The participant of " 2005 automotive safety forum " discusses and thinks its main cause: one is domestic chaotic current situation of traffic, and be often abroad car to car impact, the probability of people is little, and domestic be often that car is thrusted into, the probability of people is much bigger; Two be state one skilled in the art, driver traffic safety consciousness generally thinner, voluntary observance traffic rules few; Three is that many home-made machine motor-cars exist gap with foreign vehicle in security performance; Four is that domestic a lot of driver does not form correct driving habits, does not have grasp accident that the correct method of operating in front and back occurs; Five is that domestic road-based infrastructure also has certain gap with developed country in design planning.
Also a few money is had to be applied to car collision avoidance System in the market, such as: the bodyguard that drives, Mobileye intelligent travelling crane early warning system etc.; Some high-end cars are also provided with collision avoidance system, as Volvo, benz etc.The principle of these systems is: utilize vehicle-mounted camera or mobile phone camera to obtain the image of front truck in driving conditions, and by the spacing of certain Algorithm Analysis Image estimation and preceding vehicle, the size according to spacing is warned driver further.
But these collision avoidance systems are all early warning before occurring based on traffic accident and warning, for the product that traffic accident early warning after the occurrence of the traffic accident and collision avoidance system are not similar at present.Native system can not only produce the safety coefficient that is weighed traffic safety situation before traffic accident occurs, for prompting, alerting drivers, and achieve after the occurrence of the traffic accident, can warn the vehicle of traffic accident periphery in time, prevent the generation of second accident, simultaneously to 120, programmed emergency etc. implements to call for help in time, prevent in meagrely-populated section because rescuing the injures and deaths brought not in time.
Utility model content
The utility model provides a kind of vehicle-mounted early warning, warning and distress system key technical problem to be solved to be, change traditional only occur based on traffic accident before alarm function, and the traffic accident warning before and after occurring for traffic accident and emergency function problem to be solved.
A kind of vehicle-mounted early warning, warning and distress system, described system comprises multiple vehicle-mounted monomer be separately positioned in different vehicle, described each vehicle-mounted monomer includes micro-control unit, acceleration sensor module, wireless communication module, GPS module, GSM communication module, pilot lamp and hummer, and described acceleration sensor module, wireless communication module, GPS module, GSM communication module, pilot lamp and hummer are all connected on described micro-control unit.
Further, it is characterized in that, described micro-control unit is STM32F103RCT6 micro-control unit.
Further, described acceleration sensor module is ADXL345 acceleration sensor module.
Further, described wireless communication module is 433MHz wireless communication module.
Further, described GPS module is NEO-6M GPS module.
Further, described GSM communication module is SIM900A GSM communication module.
The beneficial effect that the utility model is compared to the prior art had is:
(1) the utility model is by judging the generation of traffic accident fast with the vehicle acceleration travelled in way;
(2) the utility model is made a response for the traffic accident accident occurred, and make warning to other vehicles in having an area of 300 meters around accident vehicle, remind car owner to enhance your vigilance, slow down, avoids the generation of second accident;
(3) the utility model provides the function of automatic transmission distress signal after the occurrence of the traffic accident, can when effectively Accident prevention occurs in meagrely-populated section, and the wounded are because rescuing the injures and deaths brought not in time.
