2. millimeter wave radar is set in car body surrounding, car body obstacle from all directions can be predicted, carry out safety method in advance.
3., under travelling the state running into emergency situation at electric car, this anti-collision detection device, also by being connected with the governor circuit on this electric car, to realize the motoring condition carrying out automatically to control electric car by governor circuit, ensure that traffic safety.
Accompanying drawing explanation
Fig. 1 is the utility model circuit theory schematic diagram.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: see Fig. 1,
Design a kind of anti-collision safety electric car, it comprises car body and is installed on the anti-collision detection device in car body with correspondence, this anti-collision detection device comprises a main control unit be made up of micro controller system (51 series monolithic), and all corresponding with this main control unit four millimeter wave radars connected, these four millimeter wave radars are corresponding to be respectively arranged on four vehicle bodies all around of electric car outside, car body obstacle from all directions can be detected.
Simultaneously, above-mentioned anti-collision detection device also comprises the data display unit be connected with main control unit, and this data display unit comprises one for showing obstacle apart from the range display of this spacing and one for showing the bearing meter of obstacle relative to this car direction.This bearing meter and range display are all arranged on the gauge panel place of steering position, to facilitate the situation of driver observation car body surrounding.
Simultaneously, described main control unit is also connected to alarm unit, this alarm unit comprises four warning lightes connecting corresponding to main control unit and phonation circuit, the mouth of described phonation circuit is connected to five sounding horn, one of them sounding horn is arranged at driver driving indoor, for reminding driver when situation occurs, other four loudspeaker are separately positioned on car body surrounding vehicle body, advance when driver controls electric car, when retreating and turn, its sounding horn sounding corresponding with vehicle traveling direction, pedestrian around electric car and automobile is reminded with this, guarantee the safety travelled.Warning light is separately positioned on tailstock both sides and headstock both sides, and equally when driver controls electric car advance, retrogressing or turns, warning light is glittering, reminds around pedestrian and automobile.
In the present embodiment, above-mentioned main control unit also can be connected with the governor circuit on electric car, under emergency situation, if driver does not make a response, main control unit can send an emergency signal to the governor circuit on electric car, to be controlled the motoring condition of this car by governor circuit, guarantee driving safety.
In electric car travels, the millimeter wave radar of its car body surrounding does not stop continuous print to the four direction all around of electric car and sends millimeter wave, millimeter wave returns received after running into obstacle, after millimeter wave radar obtains the echoed signal that obstacle returns, this echoed signal is sent in the object classifiers in millimeter wave radar, object classifiers extracts proper vector to the received signal, and classification judges, and marks off different labels to different obstacles and (such as pedestrian is numbered 1; Trees are numbered 2; Mark is numbered 3; Car number is 4 etc.), afterwards the analog-digital commutator of these label informations in millimeter wave radar being converted into digital signal feeds back in main control unit, the information of the obstacle that may collide with vehicle is extracted after main control unit Received signal strength, be passed in data display unit and alarm unit respectively, in data display equipment, the signal lamp corresponding with obstacle label is glittering (such as, if then No. 1 signal lamp is glittering for pedestrian; If trees then No. 2 signal lamps are glittering; If mark then No. 3 signal lamps is glittering; If vehicle then No. 4 signal lamps is glittering), meanwhile, the relative distance of this obstacle distance vehicle is displayed on range display, and the direction of obstacle relative vehicle is displayed in bearing meter.Driver by obstacle information shown in the data display unit on gauge panel, can control vehicle and makes correct counter-measure; In order to prevent driver not note data display unit, a standard value can be set to main control unit, when obstacle from the distance of vehicle lower than this standard value time, given a warning by the phonation circuit sounding horn controlled in operator's compartment and remind driver.Set a limit to main control unit simultaneously, when obstacle from the distance of vehicle lower than this limit time, namely under emergency situation, main control unit sends an emergency signal directly to the governor circuit on electric car, to be controlled the motoring condition of this car by governor circuit, guarantee driving safety.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
