Abstract

The utility model provides an intelligent early-warning system of traffic safety. The early-warning system includes a data collecting circuit, a data transmitting circuit, a data receiving circuit and an intelligent early-warning software. The hardware data collecting circuit is arranged on a front and a rear end of an automobile. Bluetooth wireless transmission technology is adopted in data transmission. A hardware speed and distance measuring circuit can communicate with the intelligent early-warning software running in a central embedded microcomputer through an RS 422, a USB or the Bluetooth wireless transmission technology. The intelligent early-warning system of traffic safety in the utility model can assist a driver for safe driving, and pre-determine and analyze potential traffic dangers, so as to avoid accidents. By using the intelligent early-warning system of traffic safety in the utility model, the traveling speed of an automobile in the front or in the rear as well as the distance between the automobile in the front or in the rear and the automobile equipped with the early-warning system can be measured, so as to determine whether the automobiles in the front or in the rear is over-speed, speeding up or slowing down and warn the driver to take careful of the road conditions and to drive carefully.

Description

A kind of traffic safety intelligent early-warning system
Technical field
The utility model relates to traffic safety information control technology field, relates in particular to a kind of traffic safety intelligent early-warning system.
Background technology
Along with China's rapid development of economy; Various motor vehicles significantly increase, and thing followed traffic hidden danger is also more and more, and present existing traffic management technology mode is just carried out passive management to traffic; Can not adapt to economic development and needs well; Generally take the early warning means to be mostly electromechanical instrument, instrument, settle antenna or sensor etc. along road, its defective is that method is single, systemic-function is poor, cost is high; Do not have fully reflection to cause the reason of traffic hazard and crisscross influence relation, thereby all can not extensively widely popularize application.
The utility model content
To the problems referred to above; The content of the utility model is to provide a kind of traffic safety intelligent early-warning system rational in infrastructure, novel in design, quick and easy for installation; Can driver assistance person's safe driving, the potential traffic hazard of forecast analysis is avoided the generation of accident in advance; Can measure front truck and back car go speed and distance, whether car exceeds the speed limit, quickens or slows down before and after can judging.If back car exceeds the speed limit or gives it the gun, and still run at high speed in tens meters at two cars, system makes intelligent decision, and in time alarm Ben Che driver hides; If front truck slows down or this car quickens, cause two cars at a distance of too near, system can in time remind Ben Che driver to note road conditions, safety traffic.
To achieve these goals; The technical scheme that the utility model adopted is: a kind of traffic safety intelligent early-warning system; Comprise data acquisition circuit, data transmission circuit and data receiver circuit; It is characterized in that said hardware data Acquisition Circuit is located at the two ends end to end of automobile, the Bluetooth wireless transmission technology is adopted in the transmission of data, and the hardware range-measuring circuit that tests the speed can use the intelligent early-warning software communication that moves on RS422, USB or Bluetooth wireless transmission mode and the central embedded micro computer.
Preferably; The functional unit of data acquisition circuit comprises: laser signal generator, the range-measuring circuit that tests the speed, microprocessor, power circuit unit, RS422 serial port module, USB serial port module, the data of collection can use wired mode defeated through RS422 mouth or USB oral instructions.
Preferably; The functional unit of data receiver circuit comprises: blue teeth wireless receiver, RS422 serial port module, USB serial port module; Microprocessor, power circuit unit, the data of collection can be carried out data analysis for data transmission computing machine or miscellaneous equipment easily through RS422 serial ports and USB serial ports and handled.
Above-mentioned photometry range-measuring circuit module is that the employing laser ranging (is an electromagnetic wave; Its speed is 300,000 kilometer per seconds) principle is through to testee emission laser beam, and receives the reflection wave of this laser beam, record should the mistiming; Confirm the distance of testee and test point; Laser velocimeter is the laser ranging of testee being carried out having for twice specified time interval, obtains the displacement of testee in this period, thereby obtains the translational speed of this testee; Because this laser beam is ray basically, can survey 1000 meters outer distances; The laser velocimeter precision is high, and the laser velocimeter circuit uses the safe laser of 904 nanometers, to eye-safe.
Why the utility model adopts wired mode to transmit data is earlier adopted the blue teeth wireless mode to transmit data again; Be that when on automobile, installing, system does not need automobile is done any relocating by the application scenarios decision of reality; Be installed in the car front and rear part to data collector; Data sending apparatus is installed in the indoor back seat of car top, and data sink and central embedded micro computer are installed in the automobile instrument panel top of driver right front, make things convenient for the driver to check condition of road surface.
The utility model is received as with data acquisition, wireless transmit, signal and realizes the basis; Use software to carry out the intellectual analysis prediction processing; And make prompting according to process result whether potential traffic hazard (knock into the back or collision etc.) is arranged, giving the prompting of voice and picture, the software analysis processing section is installed on the embedded micro computer of a customization; This embedded micro computer adopts ARM10 processor and Android operating system, and stable software runtime environment fast is provided.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further;
Fig. 1 is the system global structure synoptic diagram of the utility model;
Fig. 2 is the hardware circuit figure of the utility model;
Fig. 3 is the utility model software early warning surface chart.
Embodiment
Following embodiment is not as the qualification to the utility model, and all any modifications of within the spiritual principles of the utility model, being done are equal to replacement and improvement etc., all belong to the protection domain of the utility model.
As shown in the figure, a kind of traffic safety intelligent early-warning system comprises data acquisition circuit 3, data transmission circuit 2 and data receiver circuit 1; Data acquisition circuit 3 is located at the two ends end to end of automobile; Bluetooth wireless transmission 4 is adopted in the transmission of data, and the range-measuring circuit 9 that tests the speed can use the intelligent early-warning software communication that moves on mode and the central embedded micro computer of RS422, USB or Bluetooth wireless transmission 4, and data acquisition circuit 3 can directly use RS422 mouth or USB mouth to be connected with central embedded micro computer; Also can use the bluetooth approach wireless transmit to data through the data transmission circuit; Need not relocate to automobile during installation, data transmission circuit 2 is realized transmission at a distance connecing 3 data received from data acquisition circuit through the bluetooth approach wireless transmission; The range-measuring circuit 9 that tests the speed has been described the collection and the transmission of automobile relative velocity and distance; Consider that from the application scenarios of reality modular design method has been adopted in the design of system, each circuit module can work alone; Realize hardware multiplexing to the full extent, made things convenient for the actual installation of system to dispose.
