Intelligent transportation system, it is called for short ITS, advanced information technology, data communication transmission technology, Electronic transducer technology, electron controls technology and computer processing technology etc. are effectively integrated and apply to whole traffic management system by intelligent transportation system, and set up a kind of on a large scale in, comprehensive play a role, in real time, multi-transportation and management system accurately and efficiently.
Transportation is the basis of national economy, is the lifeblood of modern economy social development, is the important step of linking production and consumption, is to ensure that again people pound the means of contact contacts in the side such as political, economic, cultural, military.Transportation is the important component part of national economy, plays Link role in entire society's mechanism, provides the guarantee of strong very plinth for socioeconomic development.Transportation is not only related to national economic development and is also related to everyone growth in the living standard, thus the construction of highway is all paid much attention in countries in the world.Highway is the catalyst that modernization is economic, it is inevitably accompanied the gathering of industrial groups and spreads in the axial direction, form fast-developing " highway industrial zone " so that the most regional or even national economy all can be produced great pushing effect by construction and the operation of highway.
Utility model content
The purpose of this utility model is that provides a kind of express way driving safety precaution device based on ITS to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
This utility model includes information acquisition system, radar ranging system, warning system and master control system, described information acquisition system, described radar ranging system, communicated to connect by CAN between described warning system and described master control system, described information acquisition system is by vehicle speed sensor, lateral distance sensor, steering angle sensor, brake sensor, road conditions sensor and accelerator pedal sensor and information gathering chip form, described radar ranging system is made up of radar range finding ECU and radar sensor, described warning system is by controlling alarm chip, LCD MODULE, audible alarm module and display lamp alarm module composition, described master control system is by main control chip, RS323 serial line interface, experimental data input interface and result output interface composition.
Improve as one, pressure transducer can also be set on automobile, when colliding, the seriousness of the accident that substantially can interpolate that of pressure signal, thus send the signal in ITS intelligent transportation system, sent to other drivers or navigation system by system, it is simple to other drivers predict accident section, thus take measures to keep clear.
The beneficial effects of the utility model are:
This utility model is a kind of express way driving safety precaution device based on ITS, and compared with prior art, the present invention is used for detecting barrier and other vehicles, is finally reached active probe dangerous situation, prevents collision, thus strengthens the purpose of driving safety.These technology include radar, night vision, target recognition, image procossing, Track In Track, auto-cruising control, self-actuating brake etc..
Accompanying drawing explanation
Fig. 1 is the system structure theory diagram of the present invention.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1: this utility model includes information acquisition system, radar ranging system, warning system and master control system, described information acquisition system, described radar ranging system, communicated to connect by CAN between described warning system and described master control system, described information acquisition system is by vehicle speed sensor, lateral distance sensor, steering angle sensor, brake sensor, road conditions sensor and accelerator pedal sensor and information gathering chip form, described radar ranging system is made up of radar range finding ECU and radar sensor, described warning system is by controlling alarm chip, LCD MODULE, audible alarm module and display lamp alarm module composition, described master control system is by main control chip, RS323 serial line interface, experimental data input interface and result output interface composition.
Information acquisition system is for sensing vehicle interior and outside information, and after the information obtained is converted to the signal of telecommunication, it is transferred to main control unit subsystem, input information is the reason causing control system to change, and sensor is that the environment information (spacing of front vehicles, orientation etc.) measured is passed to control unit；Radar ranging system is used to send the data meeting its job requirement to radar range finding ECU, maintains the working environment of radar, enables radar to produce the CAN data signals such as required distance, relative velocity and angle；Master control system carries out judgement process the data from information gathering subsystem and radar according to Security Model, and the result processed is sent to acoustooptic alarm system by CAN；Sound and light alarm subsystem provides the safety state information of running car for driver.
The operation principle of automobile anti-collision alarm system: utilize the millimetre-wave radar sensor being arranged on automobile front beam to measure in real time from information such as the distance between car and target lead object and relative velocities, and be sent to main control unit by CAN network；Utilizing vehicle-mounted Hall vehicle speed sensor to record GES, feeding information gathering is given carrying out in system processing and is calculated, and calculates real-time speed value；Braking, throttle position, turning to and road surface attachment systems is input to information gathering subsystem with the form of switching value, information acquisition unit is sent to main control unit subsystem by CAN network after the information of all the sensors is processed.Main control unit subsystem carries out judgement process according to the data gathered to current traffic safety state, and provides result, then the result handled well is sent to acousto-optic warning unit subsystem by CAN network；Show an acousto-optic warning unit according to the information sent, real-time display speed and distance, if vehicle is in unsafe condition and can report to the police accordingly.System uses twice warning, if actual measurement distance is more than reminding alarm distance, system is not reported to the police, and is safe driving situation；If actual measurement is smaller than reminding alarm distance and is more than danger warning distance, display screen amber light is bright, is reminding alarm state, reminds driver to need to unclamp gas pedal；If measuring when being smaller than danger warning distance actual, display screen when red and buzzer can send long time of alarm, be precarious position, it is desirable to driver must brake hard, otherwise it is possible to dangerous generation.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
