Abstract
The utility model discloses a multifunctional reversing radar system which is characterized in that the multifunctional reversing radar system comprises a plurality of ultrasonic detection processing circuits, a reversing radar central control unit, an LCD, a reversing detection circuit, a voice prompting circuit and a regulated power supply, wherein a rear ultrasonic probe and a ranging circuit module input the data information such as the direction and distance of the obstacle at the back of the vehicle into the reversing radar central control unit; the reversing detection circuit judges whether the vehicle moves forward and backward and inputs the signal into the reversing radar central control unit; and the reversing radar central control unit operates, analyzes and processes the detection radar data, calculates the distance and direction of the obstacle at the back of the vehicle and then transmits the data to the LCD and utilizes the voice prompting circuit for voice alarm. The multifunctional reversing radar system has precise detection, stable performance, accurate alarming and simple and easy use.
Description
Technical field:
The utility model relates to a kind of multi-functional reversing radar system.
Background technology:
Traditional radar for backing car uses single CPU to come echoed signal is analyzed computing usually, then control signal is transferred to the alarm circuit and realizes its function.
There is following shortcoming in above-mentioned structure: barrier is difficult for surveying (as smooth slope, smooth spherosome, sound-absorbing cavernous body, puddle etc.) when 1) moveing backward, and the radar of tradition reversing can't give user prompt, causes and barrier collision, friction even initiation potential; 2) when extraneous weather was abominable, ultrasonic sensor sensibility can descend, and occurred the wrong report or the untimely situation of reporting to the police when causing moveing backward; Just can report to the police when 3) traditional radar for backing car has only when reversing obstacle distance tailstock certain distance, and this type of radar for backing car alarm range angle is single, the user can't differentiate the concrete distance and the angle of barrier, drives to bring inconvenience to the user.
Summary of the invention:
The purpose of this utility model provide a kind of survey precision, stable performance, warning accurately, be simple and easy to the multi-functional reversing radar of usefulness.
The purpose of this utility model is achieved by the following technical programs.
A kind of multi-functional reversing radar system, it is characterized in that: it comprises several ultrasonic listening treatment circuit, the radar for backing car central control unit, LCD, the reversing circuit for detecting, voice warning circuit and stabilized voltage supply, rearmounted ultrasonic probe and range-measuring circuit module are to the orientation of radar for backing car central control unit input rear view of vehicle barrier, data messages such as distance, the reversing circuit for detecting advances to vehicle or retreats and judges and signal is input to the radar for backing car central control unit, the radar for backing car central control unit carries out operational analysis to the detection radar data to be handled, calculate the distance and bearing of car and obstruction, again data delivery is arrived liquid crystal display displays, and the control voice warning circuit carries out audio alert.Above-mentioned described several ultrasonic listening treatment circuit comprises 4 the tunnel, is respectively ultrasonic listening treatment circuit A, ultrasonic listening treatment circuit B, ultrasonic listening treatment circuit C, ultrasonic listening treatment circuit D.
Above-mentioned described stabilized voltage supply ldo voltage regulator.
Above-mentioned described voice warning circuit is formed a complete audio amplifier circuit by peripheral circuit elements such as power discharging IC, resistance, electric capacity, loudspeaker, and the obstacle distance information that ultrasonic sensor is measured is quoted by voice mode.
Above-mentioned described radar for backing car central control unit adopts the PIC16F677 series monolithic.
The utility model compared with prior art has following advantage:
1, analyzes the echoed signal except that traditional micro computer arithmetic control circuit that passes through, two CPU technology have also been adopted, increased and from mixed and disorderly echoed signal, to have filtered out undesired signal and (for example rock key chain environment ultrasound wave, the frequency electromagnetic waves that car engine ignition produces etc.), extract useful signal, and carry out multiple logic determines, thereby realize accurate location to car and obstruction.
2, the utility model is by analyzing the distance that echoed signal can the disturbance in judgement thing, and outputs to the alarm circuit by the radar for backing car central control unit, informs the accurate distance of user's barrier, makes things convenient for the user to drive.
3, can be simultaneously the barrier of car body rear different angles be carried out Detection And Warning, strengthened the coverage of radar for backing car, improved the security that the user drives.
4, radar data is delivered to LCD, and finally with numeral, the orientation indicates piece, and voice warning circuit is reminded the driver with true man's type of alarm, reminds the driver by the vision and the sense of hearing, more intuitively and easily judges after the combination, reaches the purpose of safety reversing.
