Detailed description of the invention
The utility model embodiment provides a kind of truck active anti-collision device, and the structural representation of this device as shown in Figure 1, comprising: anti-collision early warning device 1, radar collision mainboard 3, brake appts 2 and radar sensor 4.Described radar collision mainboard is connected by communication bus with described radar sensor, anti-collision early warning device, brake appts respectively, and described radar collision mainboard comprises comparator.Above-mentioned communication bus can be 485 communication buss.
Described radar sensor comprises millimeter wave radar sensor.Millimeter wave modulation signal is outwards launched in electromagnetic mode according to the time gap of setting by the emitting antenna in millimeter wave radar sensor, receiving wire in radar sensor receives the described electromagnetic echoed signal that outer barrie thing fires back, frequency mixer in radar sensor calculates the distance value between obstacle and truck according to this echoed signal, and this obstacle distance value is transferred to radar collision mainboard.Said external obstacle is generally truck, also can be other obstacle on road.
Millimeter wave refers to the electromagnetic wave of wavelength between 1-10mm, and the RF (RadioFrequency, radio frequency) of millimeter wave is with roomy, and resolution is high, and antenna element size is little.The feature of millimeter wave ensure that it can adapt to inclement weather condition, under the weather condition that misty rain etc. as lower at visbility is just needing collision avoidance system to offer help, the mode such as laser and super sonic cisco unity malfunction, millimeter wave radar then can not be affected, and the antenna of millimeter wave radar also can not produce error because of contamination by dust, compare and be adapted at using in express highway.So, millimeter wave radar radar have lightweight, volume is little and the feature such as round-the-clock.
Described comparator is after the obstacle distance value that described radar sensor transmits is less than safety distance, and export high level to described anti-collision early warning device and brake appts, described brake appts carries out lorry brake operation, and described anti-collision early warning device sends warning.Above-mentioned comparator can for conventional amplitude comparator.
The structural representation of a kind of brake appts that the utility model embodiment provides as shown in Figure 2, comprise brake motor controller 24, motor 21, brake pedal 22 and drag decontrol 23, described motor by circuit respectively with described brake motor controller, brake pedal connects, after described brake motor controller receives high level, drive described motor rotation, brake pedal motion described in described driven by motor, carry out brake operation (electric control brake state), car retardation, in moderating process, radar sensor constantly calculates this vehicle speed and also compares with corresponding safety distance to the distance of obstacle.When the relative distance that radar in moderating process records still is less than corresponding safety distance time, initiatively crashproof mainboard provides continuation brake signal, until car speed is zero, reaches dead ship condition.
Described comparator is after the obstacle distance value that described radar sensor transmits is greater than or equal to safety distance, and output low level gives described anti-collision early warning device and drag decontrol, described anti-collision early warning device stop alarm.Drag decontrol is connected with described motor circuit, after receiving low level, stops the running of described motor, namely stops the brake operation of brake pedal.
Radar sensor on a kind of mine truck that the utility model embodiment provides is fixedly installed to schematic diagram on support as shown in Figure 3, the brandreth of a prefabricated fixed radar sensor, brandreth length 4m, is fixedly mounted on the dead ahead of truck, and brandreth lengthwise centers and truck widthwise central overlap.A radar sensor is installed in the center of brandreth crossbeam, a radar sensor is installed respectively in the left and right sides of described support.Transducer spacing is 2m, and brandreth crossbeam is 2.5m apart from floor level.
One of ordinary skill in the art will appreciate that: accompanying drawing is the schematic diagram of an embodiment, the module in accompanying drawing or flow process might not be that enforcement the utility model is necessary.
One of ordinary skill in the art will appreciate that: the parts in the device in embodiment can describe according to embodiment and be distributed in the device of embodiment, also can carry out respective change and be arranged in the one or more devices being different from the present embodiment.The parts of above-described embodiment can merge into parts, also can split into multiple subassembly further.
In sum; the utility model by arranging radar sensor, radar collision mainboard, brake appts in truck; described radar collision mainboard is connected by communication bus with brake appts; can the distance between the obstacle in truck front and truck be less than safety distance time; automatically brake operation is carried out to truck; and send warning in time; the life security of actv. protection driver, passenger, pedestrian; the generation of the serious accidents such as actv. is avoided knocking into the back with link vehicle pileup, collision, protection vehicle property safety.
Millimeter wave radar sensor radar sensor can be effectively applied in truck active anti-collision device by the utility model, ensure that chaufeur tackles complex road condition under the severe driving environment such as rain, mist, sandstorm, not by external interference: (entrucking, upward slope, descending, label, cable testing bridge, retaining wall, steep cliff) under (dust, glass), different road conditions, vehicle are achieving desirable active anti-collision effect in the same way in opposite directions under condition under different weather condition (daytime, night, rain), different ambient conditions.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
