The speed limiting system of the motor vehicle based on wireless communication can provide a speed limiting instruction for the automobile in traveling, can effectively prevent the overspeed of the automobile and has great social benefit.
Description
Technical field
The utility model belongs to field of traffic and wireless communication technology field, relates to a kind of motor vehicle speed limiting system based on radio communication.
Background technology
Modern society, automobile is increasing, but the problem of driving over the speed limit is the chronic disease of society always, annual because driving over the speed limit of automobile caused the human world tragedy of many car crashes.Effectively prevent to drive over the speed limit is the difficult problem that traffic department faces always; existing system; can only detect the speed of a motor vehicle; find that automobile has the hypervelocity behavior, the driver to this automobile punishes again, and this pattern of afterwards handling can not prevent the social danger that overspeed driving car brings timely and effectively; therefore; be necessary to set up a cover real-time and effective speed limiting system, to stop the phenomenon of overspeed driving car, the protection people's the security of the lives and property.
The utility model content
The utility model wants the technical solution problem to provide a kind of motor vehicle speed limiting system based on radio communication, this motor vehicle speed limiting system based on radio communication provides the speed limit instruction for the automobile in travelling, can effectively prevent overspeed driving car, have the huge social benefit.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of motor vehicle speed limiting system based on radio communication is characterized in that, comprises automobile and a plurality of speed limit transmitting instructions devices that are arranged on different speed limits highway section; Each speed limit transmitting instructions device is to there being a signal cover; Automobile is provided with automobile microprocessor, automobile drive mechanism, speed pickup and speed limit command receiver; Described automobile drive mechanism, speed pickup and speed limit command receiver all are connected with the automobile microprocessor; Speed limit command receiver on the automobile is connected with the speed limit transmitting instructions device radio communication of setting in the current region of automobile.
Described motor vehicle speed limiting system based on radio communication also comprises the display that is used to show current vehicle speed and current speed limit; Described display is connected with the automobile microprocessor.
The beneficial effects of the utility model:
This based on the motor vehicle speed limiting system of radio communication based on wireless communication technology, when running car, receive the speed limit instruction in real time, and Control of Automobile is travelled Shi Buhui above this speed limit, after each automobile joins this system automatically, even the driver thinks hypervelocity, and is also impossible.Like this, the phenomenon of just fundamentally having stopped overspeed driving car takes place, and for protecting the people's lives and property safety and building a harmonious society, all has huge meaning.
Description of drawings
Fig. 1 is the structural principle block diagram of embodiment 1.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
As Fig. 1, a kind of motor vehicle speed limiting system based on radio communication comprises automobile and a plurality of speed limit transmitting instructions devices that are arranged on different speed limits highway section; Each speed limit transmitting instructions device is to there being a signal cover; Automobile is provided with automobile microprocessor, automobile drive mechanism, speed pickup and speed limit command receiver; Described automobile drive mechanism, speed pickup and speed limit command receiver all are connected with the automobile microprocessor; Speed limit command receiver on the automobile is connected with the speed limit transmitting instructions device radio communication of setting in the current region of automobile.Described motor vehicle speed limiting system based on radio communication also comprises the display that is used to show current vehicle speed and current speed limit; Described display is connected with the automobile microprocessor.
Speed limit transmitting instructions device is arranged on the urban district needs speed-limiting road section, and it is along the line also to be installed in the expressway.In the highway section that inaccurate motor vehicle enters, speed limit can be set to 0.
The wireless technology that adopts between the speed limit command receiver on speed limit transmitting instructions device and the automobile: comprise the frequency modulation wireless mode,, can also use the communication of medium wave or long wave as the mode that urban district frequency modulation (FM) radio uses; Specific implementation is: at first set up unified wireless communication protocol, comprise speed limit in the data of transmission, after the speed limit command receiver is received data, these data are decoded, obtain speed limit.The frequency modulation wireless technology and the communication protocol that adopt are existing mature technology.
The principle of work of native system is as follows:
(as every 5 seconds) of the timing of speed limit transmitting instructions device sends a broadcasting packet to its signal coverage areas, contain coding in this broadcasting packet to the current region speed limit, after automobile enters the overlay area of this idsplay order transmitter, the speed limit command receiver is just received this broadcasting packet, the automobile microprocessor decodes the speed limit instruction from this broadcasting packet, as 60km/h, the automobile microprocessor detects the current vehicle speed of automobile with speed pickup, be higher than the corresponding speed limit of this speed limit instruction when detecting this speed of a motor vehicle, then the driving mechanism of Control of Automobile slows down automatically, and car speed is decelerated in the speed limit.If current vehicle speed is less than speed limit, then speed limit does not make a difference to travelling of automobile.Like this, by the automatic control system of a closed loop of speed pickup, microprocessor, driving mechanism and speed limit receiver module (speed limit command receiver) formation, avoid driving over the speed limit of automobile.Display on the automobile is used to show the current speed limit and the current speed of a motor vehicle.
