Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme of the embodiment of the present invention, below the accompanying drawing that embodiment describes required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
The collision warning device composition schematic diagram that Fig. 1 provides for the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
The invention provides a kind of collision warning device, including controlling module 2, locating module 1, communication module 3, display module 6, alarm module 4, execution module 5 of reporting to the police;
Locating module 1 obtains speed and the position data of mobile platform, and is undertaken transmitting described speed and position data to communication module 3 by controlling module 2;
Described packing data is transmitted by communication module 3 by wireless channel, accepts packing data transmission extremely control module 2 that in a range of wireless channel of periphery, other mobile platforms send simultaneously;
Control the packing data of the module 2 periphery mobile platform to receiving resolve the speed that obtains periphery mobile platform and position data and send to alarm module 4, control module 2 according to this mobile platform self speed and position data and the quantity of periphery mobile platform and the transmit power of status information Self Adaptive Control communication module 3 and transmission frequency;
Alarm module 4 receives the speed of described each mobile platform and position data and sends warning signal according to described alarm regulation storehouse and perform module 5 to reporting to the police, execution module 5 of reporting to the police receives described warning signal and performs operation of reporting to the police, and display module 6 receives described warning signal display alarm information.
In the present embodiment, described position data includes travel direction and the distance of mobile platform. Certainly, the present invention can also be added as needed on other positional informationes to described position data, and position data is not specifically limited by the present invention.
The described warning signal that the present embodiment provides includes front vehicles jerk or low coverage low speed warning signal, front vehicle low coverage high speed warning signal, and side vehicle collision prewarning signal, be blocked in sighting distance vehicle early warning signal. Warning signal provided by the invention not only includes above-mentioned concentration signal, it is also possible to be added as needed on other early warning signal, and the present embodiment is only one of the present invention preferably embodiment.
Wherein report to the police and perform module 5 by alarm lamp or voice execution warning operation.
