Description
Technical field
The utility model relates to a kind of radar for backing car, particularly a kind of non-blind area radar for backing car based on wireless transmission.
Background technology
Along with the development of society; improving constantly of living standards of the people; automobile application is in daily life more and more extensive; thus the safety problem in docking process receives increasing attention; owing to there is certain vision dead zone in reversing process; therefore in real process, often there will be all kinds of accident, result in the infringement of automobile.The safety feature being applied to automobile assisting car backing at present mainly contains phonetic alarm device, radar for backing car and back-sight visual system etc.Phonetic alarm device is not because act on for non intelligent obstacle, and the actual effect used is poor; Barrier after car can be carried out the display of complete display by rear-view system for automobile, but the cost prohibitive of back-sight visual system, there is the problem that popularity rate is not high in actual applications; Automobile reversing radar system is applied comparatively extensive at present, can test the distance between barrier and automobile, and can be shown by audio alert or display unit.
The components and parts that reversing radar of vehicle design in the past uses are more, and multiplex wire transmission signal causes complex circuit in car; And there is very large blind area, often cause measuring the partial impairment thing less than automobile tail.
Utility model content
For the deficiency that prior art exists, the utility model provide a kind of can the abundant radar for backing car of Measurement accuracy automobile tail barrier and structure simple functions.
The utility model is achieved through the following technical solutions: a kind of non-blind area radar for backing car based on wireless transmission, comprise ultrasonic distance measuring module, single-chip microcomputer first, wireless sending module, wireless receiving module, single-chip microcomputer second, LCD display and alarm module, described ultrasonic distance measuring module is connected with described single-chip microcomputer first, described single-chip microcomputer first is connected with described wireless sending module, described wireless sending module and described wireless receiving module wireless connections, described wireless receiving module is connected with described unit sheet second, described single-chip microcomputer second and described LCD display, described alarm module connects respectively, described ultrasonic distance measuring module attaching has stepper motor, ultrasonic distance measuring module is driven to carry out the rotation of different angles by stepper motor, thus measure the distance of differing heights barrier and automobile tail.
Further, described single-chip microcomputer first and single-chip microcomputer second all adopt STC89C52RC single-chip microcomputer, thus carry out analyzing and processing acquisition distance to the signal that ultrasonic distance measuring module is passed back.
Compared with prior art, the beneficial effects of the utility model are:
1, the mode of employing wireless transmission of the present utility model realizes the separate design of obstacle detector and warning device, according to actual needs and can observe and conveniently placing, and warning device can be carried with by car owner after stopping, can realize when there being people close to automobile, this radar for backing car can realize reporting to the police, and car owner can find immediately;
2, the utility model adopts step motor control ultrasonic distance measuring module to carry out the rotation of different angles, can realize towards measurement, omnibearing detection is carried out to the barrier after car, avoid in testing process because partial impairment thing is lower, angle is fixed and is occurred situation about cannot accurately find range, drastically increase effect and the accuracy of range finding, realize non-blind area and measure.
Accompanying drawing explanation
Accompanying drawing is structured flowchart of the present utility model.
Embodiment
A kind of non-blind area radar for backing car based on wireless transmission, comprise ultrasonic distance measuring module, single-chip microcomputer first, wireless sending module, wireless receiving module, single-chip microcomputer second, LCD display and alarm module, described ultrasonic distance measuring module is connected with described single-chip microcomputer first, described single-chip microcomputer first is connected with described wireless sending module, described wireless sending module and described wireless receiving module wireless connections, described wireless receiving module is connected with described unit sheet second, described single-chip microcomputer second and described LCD display, described alarm module connects respectively, described ultrasonic distance measuring module attaching has stepper motor, ultrasonic distance measuring module is driven to carry out the rotation of different angles by stepper motor, thus measure the distance of differing heights barrier and automobile tail.
Further, described single-chip microcomputer first and single-chip microcomputer second all adopt STC89C52RC single-chip microcomputer, thus carry out analyzing and processing acquisition distance to the signal that ultrasonic distance measuring module is passed back.
Workflow of the present utility model is specially: first ultrasonic distance measuring module is found range to barrier, signal is passed to single-chip microcomputer first, distance is obtained after the analysis of single-chip microcomputer first, then by wireless sending module, distance signal is sent, wireless receiving module passes to single-chip microcomputer second after receiving distance signal, result is shown on liquid crystal display LCD by single-chip microcomputer second, then the data received and threshold value is compared, if the measurement result received meets alert if, starts alarm module; If after the distance received is greater than threshold value, contact alarm.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
