Abstract
The utility model provides the technical scheme of a small vehicle reversing radar. The small vehicle reversing radar comprises a plurality of ultrasonic distance measuring modules provided with ultrasonic distance measuring probes. The ultrasonic distance measuring modules are connected with a main processor through a dip switch. The main processor is connected with an audio power amplification module through a voice module. The audio power amplification module is connected with a playing loudspeaker. In addition, a power module for supplying power to each module exists. According to the radar of the scheme, the problem that a blind spot exists on a rearview mirror in the reversing process can be solved, and the switch-on and switch-off of the ultrasonic distance measuring probes can be controlled through the dip switch to make the distance measuring process is more directional.
Description
Technical field
The utility model relates to a kind of radar for backing car for household small-size vehicle.
Background technology
Along with the raising of people's living standard, vehicle has goed deep into people's life, but in the process of use vehicle, have the appearance of problems, during such as reversing there is blind spot and block in sight line, and can have error by the observed distance of rearview mirror, the radar for backing car using at present, take measurement of an angle little, adjustment direction of measurement that can not be random, this is the deficiencies in the prior art parts.
Summary of the invention
The utility model provides a kind of technical scheme of dilly radar for backing car, the radar of this programme has solved rearview mirror in reversing process and has existed the problem of blind spot, and, can be by the switch of toggle switch control ultrasonic ranging probe, make range finding have more directivity.
This programme is realized by following technology: a kind of dilly radar for backing car, feature is: comprise multiple ultrasonic distance measuring modules with ultrasonic ranging probe, ultrasonic distance measuring module is connected with primary processor by toggle switch, primary processor is connected with an audio power amplification module by voice module, described audio power amplification module is connected with broadcasting loudspeaker, in addition, there is a power module to modules power supply.
Described ultrasonic distance measuring module adopts HC-SR04 chip.
Described voice module adopts ISD400X chip.
Described audio power amplification module adopts TDA2822 chip.
Described ultrasonic distance measuring module is 3.
Each ultrasonic distance measuring module is connected with two ultrasonic ranging probes.
Owing to there being multiple ultrasonic distance measuring modules in the technical program, and each ultrasonic distance measuring module is connected with two ultrasonic probes, so just can measuring vehicle by ultrasonic probe and the distance of external object, three ultrasonic distance measuring modules are connected with primary processor by toggle switch, human pilot can be connected different ultrasonic distance measuring modules by toggle switch like this, while reversing like this, human pilot can only use the radar of a direction, makes detection range more targeted; Ultrasonic distance measuring module adopts HC-SR04 chip, stable performance, and distance accuracy is high.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Brief description of the drawings
Fig. 1 is the electric diagram of the utility model embodiment.
In figure, 1 is ultrasonic ranging probe, and 2 is ultrasonic distance measuring module, and 3 is toggle switch, and 4 is primary processor, and 5 is voice module, and 6 is audio power amplification module, and 7 for playing loudspeaker.
