[0018] The following is a further detailed description through specific implementation modes: Embodiment
[0019] As Figures 1-4 shown, the test robot for testing motion sickness in vehicles is in a sitting posture, and the robot is made of rigid plastic material. The head 1 and chest 2 of the robot are both hollow. In order to install various test instruments, core board 3 and power supply 4, the robot uses a portable replaceable power supply as the output end to provide energy output for various detectors and sensors. A transmission shaft 101 is provided at the connection between the head 1 and chest 2 of the robot to realize the deflection of the entire head of the robot. Two sets of rotating shaft systems 102 are provided inside the head of the robot, namely a horizontal transmission system and a vertical transmission system. The two transmission systems are respectively connected to two stepper motors and connecting gears, and the two transmission systems realize the horizontal rotation and vertical rotation of the robot's head; The horizontal rotation and vertical rotation of the robot's head increase the robot's line of sight, enabling the robot's line of sight range to fully simulate that of a real person; Inside the chest of the robot, there are a vertical beam 201, a truss 202, a horizontal plate 203 and a base 204. The base 204 is provided with screw holes and a vertical connecting extension plate. The screw holes on the base enable the base to be installed on the pelvic structure of the robot, and the vertical connecting extension plate facilitates the connection of the vertical beam. Multiple screw holes are also provided on the vertical beam, enabling the truss and horizontal plate to be installed on the vertical beam. The transmission shaft is connected to the top of the vertical beam.
[0020] Inside the chest cavity of the robot, there are a core board 3, a GPS locator 5, a vibration sensor 6, a power supply 4, and a DC-DC voltage regulator 7. The power supply 4 is connected to the DC-DC voltage regulator 7 through a cable. The power supply 4 is connected to the DC-DC voltage regulator 7 and then to the core board and each detector. After the DC-DC voltage regulator converts the 24V voltage of the power supply into 5V voltage, it then transmits the current to each detector and the core board, and the voltage regulator plays a role in stabilizing the voltage in the circuit; The core board is connected to each detection module, and the core board operates in multiple processes. That is, when it is powered on and running, multiple detection modules run simultaneously. The core board is divided into several receiving areas, and each receiving area respectively receives the detection data of each detection module. And the core board has a processing area in the middle of each receiving area. The middle processing area summarizes the data of multiple detection modules, organizes the data, and stores it in the form of generating an excel table.
[0021] The vibration detection module includes two vibration sensors, which are respectively set in the head and the chest cavity. The two vibration sensors are respectively used for detecting the X-axis acceleration (g), Y-axis acceleration (g), Z-axis acceleration (g), X-axis angular velocity (g), Y-axis angular velocity (g), Z-axis angular velocity (g), X-axis vibration velocity (mm / s), Y-axis vibration velocity (mm / s), Z-axis vibration velocity (mm / s), X-axis vibration angle (°), Y-axis vibration angle (°), Z-axis vibration angle (°), X-axis vibration displacement (um), Y-axis vibration displacement (um), Z-axis vibration displacement (um), X-axis vibration frequency (Hz), Y-axis vibration frequency (Hz), and Z-axis vibration frequency (Hz) at the chest position and the head, and makes a preliminary determination of the data correlation between vibration and motion sickness by comparing the time-axis relationship of the above data with the sensory time-axis data of a real person.
[0022] The space detection module combines a lidar and a camera. The lidar is located at the forehead position of the robot. The lidar is used to detect the distance between the object in front and the robot and form a high-quality depth image, and the camera generates an image of the object in front of the robot's line of sight; The line-of-sight detection module is a camera, which is located at the nasal bone position of the robot. The horizontal line-of-sight angle of the camera is 160°, and the vertical line-of-sight angle is 120°. The line-of-sight angle of the camera is the same as that of a human eye. It combines with the lidar to record the data of the line-of-sight distance and line-of-sight range of the robot, and in the same way as the vibration module, makes a preliminary determination of the data correlation by comparing with the sensory data of a real person on the time axis.
[0023] The motion sickness position detection module is a GPS locator. The GPS locator is installed on the cross plate inside the robot's chest cavity. The GPS is used to record the moving trajectory of the robot. This data record is used to test the impact of the travel length on the incidence of motion sickness. This data is collected in segments and the collected values are set manually.
[0024] Advantages of the embodiment: In this embodiment, through the tests of data such as the moving trajectory, vibration amplitude, line-of-sight angle, and line-of-sight distance, the relationships between these data and the onset of motion sickness as well as the relationships between specific values are studied. And in this embodiment, by setting up a robot similar to the human structure, the test data is made close to the real human test data, and the data is visualized. Combining with the real human sensory data, a motion sickness correlation data standard is sorted out.
[0025] The usage method of the above-mentioned test robot for testing motion sickness in automobiles includes: Place the robot in the back row of the vehicle and fasten the seat belt. Start the vehicle, connect the robot to the computer, turn on the external switch of the robot. A real person sits next to the robot. When the vehicle is running, the robot will also collect vibration data, position data, and line-of-sight data in real time. The test time is 3 hours. After the data test is completed, the core board automatically sorts the data into a table and outputs it to the computer terminal; Based on the above steps, the operation of the robot can be controlled by a manual switch in the middle. The switch button is at the external switch 8, and the operation time of the robot is the time provided by the battery for power supply.
[0026] The above are only the embodiments of the present invention. Specific structures and common knowledge such as characteristics that are well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the present invention.
