In order to make the reflection characteristic of the 77GHz millimeter wave radar of the soft target object of the pedestrian approach to the real pedestrian as much as possible, the soft target object of the pedestrian should avoid using metal parts, and at the position where the metal parts must be used, the metal parts can be covered by a material which absorbs radar waves or a material which can disperse radar wave reflection, so that the radar reflection of the whole soft target object of the pedestrian is more uniform.
The manufacturing process comprises the following steps:
as shown in fig. 4, the preparation method of the pedestrian soft target comprises the following steps:
s1, cutting a sheet material with a corresponding shape according to a cross section of the human body model after transverse or longitudinal segmentation;
s2, based on the sheets 8 cut in the step S1, in order to achieve higher stacking precision, a corresponding positioning function is required, and each sheet is provided with at least 2 non-overlapped circular positioning holes or at least 1 non-circular positioning hole;
s3, stacking the sheets 8 into a formed model, and inserting at least one hard framework into the model in order to ensure that the model has good stability and prevent the stacked model from displacing or separating from the section after being impacted.
After the model is stacked, the model can be continuously refined, so that the model is more vivid.
The working principle is as follows:
all the motors are synchronously controlled by the driving module, and the swinging step length and frequency of the artificial limb of the pedestrian are simulated by synchronously controlling the reciprocating swinging angle and period of each motor, so that the common actions of swinging legs, swinging arms, swinging heads and the like of the pedestrian during walking are simulated.
Based on the mechanism characteristics in the arm artificial limb, the upper limb and the lower limb can present periodic actions along with the swinging of the arm artificial limb, and the upper arm starts swinging forwards in a reverse direction after swinging to the last direction by assuming that a certain state of the arm is taken as a starting moment; due to inertia, the lower arm without power drive keeps a backward movement state, so that the angle of the arm is increased, the lower arm gradually recovers a bending state along with the continuous swinging of the upper arm due to the pulling force at the joint of the arm prosthesis, the upper arm starts to swing backward in a reverse direction after swinging to the forefront, the lower arm keeps bending in the process of swinging backward until the lower arm returns to the state at the starting moment, and the lower arm moves backward due to inertia, so that the lower arm reciprocates. Due to the design of the outer waterproof cloth of the arm artificial limb, the maximum angle of the arm in the swinging process can be effectively controlled.
Based on the mechanism characteristics of the leg prosthesis, along with the swing of the leg prosthesis, the upper limbs and the lower limbs of the leg prosthesis present periodic actions, and if a certain state of the leg is an initial time, the thigh swings to the forefront and then starts to swing backwards in a reverse direction, the unpowered shank keeps a state of straightening motion, and along with the continuous swing of the thigh, the thigh swings to the last and then starts to swing forwards in a reverse direction, and in the forward swinging process, the shank keeps a state of backwards moving due to inertia, so that the angle of the thigh and the shank is reduced, the shank starts to bend, in the forward swinging process, the shank starts to return to the straightening state due to the pulling force at the joint of the leg, and until the initial time is returned, the shank straightens, and the thigh starts to move backwards, so that the reciprocating motion is realized. Due to the design of the outer covering layer of the leg prosthesis, the maximum angle of the leg during the swinging process can be effectively controlled.
The WIFI module is arranged in the soft object of the pedestrian, can be connected with external equipment in a wireless mode, sets the frequency of swing arm/leg swing/head turning actions through the external equipment, and can also receive specific starting signals to trigger the starting of the motor.
The interior of the pedestrian soft target object needs to be protected from power failure when falling down, and when the pedestrian soft target object is impacted by a vehicle, the motor can be automatically powered off, so that the motor is prevented from being damaged when falling down.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
