Embodiment
Below in conjunction with accompanying drawing, the present invention is explained in detail:
The concrete structure of this device is such as Fig. 1, and by sensor assembly, data processing module and information displaying reminding module three part form.
Sensor assembly comprises: camera a101, camera b102, camera c103, radar a201, radar b202, radar c203, radar d204, radar e205, radar f206, radar g207, radar h208, radar i209, radar j210, potentiometer a300, potentiometer b301; Radar model is hc-sr04, and camera model is ccd camera.
Data processing module comprises: data input module 401, central processing unit 402, screen partition device 601;
Information displaying reminding module comprises: display screen 600, hummer 500.
Apart from 20cm place, both sides on trailer compartment 1000 afterbody collision bumper, radar d204, steering wheel d704, radar g207, steering wheel g707 are installed respectively, radar d204 and steering wheel d704, radar g207 and steering wheel g707 bond together and are connected on trailer collision bumper by mounting bracket 900, radar e205, radar f206, be directly connected on trailer collision bumper by mounting bracket 900.
Sensor section adopts 3 cameras and 10 radars to carry out Information Monitoring altogether. Adopting the Vehicular accumulator cell of 12v to be energized to steering wheel, steering wheel swings with radar, so that radar gathers two jiaos, compartment peripheral information.
In the middle of radar d204 and radar g207, separately fill two same model radar e205 and radar f206 by mounting bracket is equidistant, on trailer afterbody collision bumper, in order to gather the range information of trailer afterbody obstacle.
Equidistantly installing three radars with mounting bracket respectively on the vehicle frame of both sides, trailer compartment, right side is followed successively by radar a201, radar b202, radar c203, and left side is followed successively by radar j210, radar i209, radar h208 from front to back; These six radars link together with steering wheel a701, steering wheel b702, steering wheel c703, steering wheel 710, steering wheel 709, steering wheel 708 respectively, to obtain the range information of peripheral obstacle. This model radar totally four pins, wherein two pins are in order to connect power supply, and the positive pole power supply positive and negative electrode corresponding with data processing module respectively to negative pole is connected.
Sensor section constrained input end is connected with output, the input terminus of data input module 401 respectively, inputs 20khz frequency wave by controller chip to each radar, inspires each radar and send ultrasonic wave. After ultrasonic wave returns, each radar calculates obstacle distance according to the time difference. The range information that all radars collect passes to the input terminus of data input module 401 by its Echo end (sending end).
Adopt mounting bracket 900 that a camera c103 is installed in the middle part of trailer compartment 1000 afterbody collision bumper, fill camera a101 and camera b102 in addition in the both sides of trailer front end respectively, tilt 15 ° downwards. The supply lead of all cameras is connected with 12v store battery, namely by battery power. Each camera output terminal is connected with data processing module, the graphic information input that will collect.
In the junction in trailer compartment 1000 with tow tractor 800, potentiometer a300 is installed, to obtain the connection angle of tow tractor 800 with trailer compartment 1000. A potentiometer b301 is installed below tow tractor bearing circle 303, consults Fig. 3, control steering wheel angle to obtain officer in real time. Potentiometer b301 and potentiometer a300 output terminal are connected with data input module 401.
The tow tractor 800 recorded by the steering wheel angle measured by rotation angular sensing device b301 and potentiometer a300 and the connection angle in trailer compartment 1000 reach data processing module;
In data processing module, the input port of data input module 401 is connected with Echo end (sending end) mouth of each radar, namely receives the distance of the obstacle of all radar detections, all distances is compared by programmed algorithm, draw minor increment, then compare with safe distance. If minor increment is less than one-level safe distance, then central processing unit 402 controls hummer 500 and sends high frequency sound. If minor increment is greater than one-level safe distance and is less than two level security distances, then hummer 500 sends low frequency sound. If minor increment is greater than two level security distances, then show trailer safety, hummer 500 not sounding. The signal of the output of camera obtains numerary signal after analog to digital conversion module, the central processing unit 402 (model is al422b) being made up of queue-type storage chip stores, the graphic information of each frame is extracted by interruption controls, when trailer compartment 1000, certain side radar range is less than two grades of exposure distances, data processing module is processed by the graphic information of algorithm by corresponding side camera, deepens by the red value of pixel in image. The upper right corner that the shortest distance of each radar detection is displayed in the image of right side camera collection by algorithm routine, i.e. the shortest distance numeral of certain radar detection is corresponding with the rgb value of image upper right corner pixel. The graphic information of each camera after treatment is exported by the output port of controller after digital-to-analog conversion, is connected with video dispenser 601 by output port, and the output terminal of video dispenser 601 is connected with display screen 600.
The tow tractor 800 recorded by the steering wheel angle measured by potentiometer b301 and potentiometer a300 and the connection angle in trailer compartment 1000 reach data processing module, after data processing module extracts corner, algorithm based on the motion model of trailer is by the motion track of corner and the distance analysis trailer of all radar detections, the image of track with trailer rear is combined, namely in the picture set up virtual coordinate system, track is corresponding pixel in correspondence image then, is changed the rgb value of respective pixel point by algorithm routine.
Video dispenser 601 controls the graphic information after display screen 600 display process, the i.e. graphic information of display screen 600 left side (right side) upper part display tow tractor 800 left side (right side) side camera collection, the graphic information of trailer compartment 1000 afterbody camera collection is shown in display screen 600 bottom, and the prediction locus of mark trailer. When a trailer left side (right side) side radar detection shortest distance is less than two level security distances, upside, display screen 600 left side (right side) image is shown as redness, to represent dangerous. The shortest distance of each radar detection is displayed in the image of the upper right portion of display screen 600.
The connection of radar and steering wheel is consulted shown in Fig. 2, a bonding tubular shaft matched with steering wheel output shaft in the lower section of each radar probe, it is fixed together by output shaft and this parts of steering wheel, after being energized to steering wheel, steering wheel output shaft rotates, drive this tubular shaft axle to rotate, namely drive radar probe to rotate. Each steering wheel is connected with trailer by mounting bracket 900, and the structure of mounting bracket 900 consults Fig. 4, sway brace a901, the sway brace b902 that mounting bracket stretches out, it is fixed with stub a906, stub b907, clip the both sides of steering wheel, fix by steering wheel and mounting bracket 900, screw passes the respective screw hole a903 bottom mounting bracket 900, threaded hole b904, threaded hole c905 are connected with trailer compartment 1000, is fixed on trailer by mounting bracket 900.
