Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below the technical scheme in this utility model is clearly and completely described, it is clear that described embodiment is a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Fig. 1 is this utility model preventing car from close trailing collision prior-warning device structured flowchart, as it is shown in figure 1, the preventing car from close trailing collision prior-warning device that this utility model provides, including: information acquisition module, communication module, micro-control module, warning and brake module；Described information acquisition module, communication module are connected with the signal input part of micro-control module, report to the police and are connected with the signal output part of micro-control module with brake module.
Specifically, described information acquisition module includes: distance measuring sensor, tachogenerator, rotation direction sensor, braking sensor.Described distance measuring sensor is ultrasonic sensor.Described tachogenerator is Hall vehicle speed sensor.Described warning includes with brake module: audible alarm unit, display lamp alarm unit, braking motor brake unit.
Microcontroller of the present utility model is single-chip microcomputer, and employing model is STC12C5A60S2.
Whole system have employed wireless communication technology and realizes inter-vehicle communication, carries out speed and the transmission of car braking information so that automobile early warning is quicker.Radio communication uses ZigBee technology, and model is WeBeeCC2530.
This utility model also provides for a kind of preventing car from close trailing collision method for early warning, as in figure 2 it is shown, comprise the following steps:
Step one: utilize information acquisition module the information of front truck to be collected, and the information of collection is sent to micro-control module；
Step 2: the information of reception is sent to the microprocessor module of rear two cars by micro-control module by communication module；
Step 3: the micro-control module of rear two cars carries out judgement process according to the information received to current traffic safety state；
Step 4: if the result processed meets one-level and reports to the police, then micro-control module is to reporting to the police and brake module transmission warning message, carries out and reports to the police；Described one-level is reported to the police as being made a response prevented from knocking into the back by bright light and information of voice prompt prompting driver；
If the result processed meets secondary alarm, then micro-control module is to reporting to the police and brake module transmission warning message, carries out secondary alarm；Described secondary alarm prevents from knocking into the back for making car braking by bright light, audio alert and startup braking motor at once.
Specifically, whole system includes distance measuring sensor, tachogenerator, rotation direction sensor, braking sensor, microprocessor, buzzer, display lamp, braking motor and ZigBee radio communication, distance measuring sensor, rotation direction sensor, braking sensor are connected with the input of microprocessor, and buzzer is connected with the outfan of microprocessor respectively with braking motor.
The operation principle of pre-alarming system for preventing car from close trailing collision: as shown in Figure 2, real-time Transmission speed and braking information are connected when the Following Car of three cars completes three inter-vehicle communications in time reaching predetermined communication distance (communication distance is divided into closely, in, remote third gear) according to speed difference, utilization is arranged on the ultrasonic sensor on automobile front beam and the tailstock and measures in real time from information such as the distance between car and target lead object and relative velocities, and is sent to microprocessor module；Utilize vehicle-mounted Hall vehicle speed sensor to record GES, send and microprocessor module is carried out process calculating, calculate real-time speed value；Braking and direction information are obtained by electromagnetic transducer and are input to microprocessor module；The information that the front truck that communication module obtains sends is input to microprocessor module.Microprocessor module 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 alarm output unit；Alarm output unit, according to the information sent, is reported to the police.If vehicle is in unsafe condition and can report to the police accordingly, that is: while front truck or rear car are braked, braking information sends, remaining two car obtains its braking information and obtains pre-warning time according to three car speeds and position, if the time does not reports to the police more than one-level time of fire alarming, otherwise report to the police, proceed two grades of judgements simultaneously, if pre-warning time is more than the secondary alarm time, do not report to the police, otherwise audio alert, the same time starts braking motor and is braked, so that three workshops keep safe distance between vehicles.
Alarm device flow process is as follows: front truck sends the information such as the preceding object information collected and Ben Che braking, remaining two car obtains information described in front truck by communication module and obtains result by microprocessor processes, then one-level judgement is carried out according to result, if result meets one-level reports to the police (driver need to be pointed out to make a response prevent from knocking into the back), then report to the police, otherwise do not report to the police；Report to the police and proceed two grades of judgements simultaneously, if result meets secondary alarm (must make car braking otherwise will knock into the back) at once, report to the police, start braking motor simultaneously and be braked, so that three workshops keep safe distance between vehicles.
As shown in Figure 3, information receives flow process: No. 1 car is collected the information such as preceding object information and Ben Che braking and is sent to micro-control module, being sent to be followed by 2, No. 3 cars by communication module, two cars accept information and judge vehicle whether safety according to information processing.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
