Therefore, in order to meet the comfort of operators in work, the work efficiency in work is improved, and the action research analysis aiming at special gestures in the working environment is necessary.
The human body size is a national production and development technical basis, relates to various aspects of clothing and food residence and the like, and is widely applied in the fields of industry, construction, medical treatment, transportation and the like. With the continuous progress and development of the scientific society, anthropometric techniques have undergone a transition from manual measurement to automated measurement, from contact measurement to noncontact measurement, and from two-dimensional measurement to three-dimensional measurement.
Currently, the anthropometric methods can be classified into a contact type measuring method and a non-contact type measuring method. Anthropometric techniques can be further divided into common measurement techniques and three-dimensional digital anthropometric techniques. The common method for measuring the characteristic dimension of the human body mainly relies on measuring instrument equipment such as a tape measure, a altimeter, a distance meter, an angle meter and the like to acquire the length, width, height, angle and other information of different parts of the human body. Manual measurement is convenient to operate, the principle is simple, and almost all human body size data can be obtained, but with the development of the society age, factors such as large measurement error, low efficiency, low degree of automation, subjective experience of measurement personnel and the like are unavoidable in the test process. The three-dimensional digital human body measurement technology has the characteristics of high efficiency, rapidness, accurate data acquisition, time saving and wide application in different industries. However, generally, three-dimensional scanning technology has high cost, only larger objects can be scanned, only the external contour of the objects can be obtained, and the internal structure of the objects cannot be studied. Therefore, the two measurement techniques have advantages and disadvantages and need to be combined with each other to adapt to the requirements of the modern society.

Posture requirements: the nose is attached to the measuring reference plate 8, the two hands are supported on the horizontal plane to be vertical to the arms, the back is parallel to the horizontal plane and is kept in a vertical state with the thighs and the arms, the two shanks and the insteps are respectively attached to the horizontal plane, and the head is raised to the maximum height, as shown in fig. 12.
Measurement data:
x axis: distance from X0 to toe (measuring length of relative position of human body in this posture)
Lateral distance: the measured X-axis distance + a fixed value B (distance from Y0-X0) (measuring the width of the relative position of the human body in this posture.)
And Z axis: the vertical distance from the highest part of the head to the ground (measuring the relative height of the human body in this posture).
Recording data: after the gesture is accurate, the save key of the software is pressed and the data is recorded in an Excel table.
Specifically, the tested person is prone on the test bench according to the requirement, after the measurement personnel are adjusted to move the X-axis and the Z-axis grating scales to the specified size positions, the prone posture length e is the horizontal distance from the nose tip point to the toe tip point of the tested person in the prone posture, the prone posture height f is the vertical distance from the highest point of the head of the tested person to the horizontal ground in the prone posture, and the specific posture size is shown in the figure. And then, another measurer records the data displayed by the digital display table on paper, and the calculated e and f values are timely input into the Excel table.
At least three sets of data are measured for each posture of each person, and the average is taken by multiple measurements.
Example 4
Unlike the embodiment 1, the measurement device for the human body size in the special posture is shown in fig. 6, and is directly fixed on the horizontal test platform 1 (in a fixing manner such as a bolt, etc.), the measurement reference plate 8 comprises a bottom plate and a vertical plate, the bottom plate and the vertical plate are vertically arranged, the bottom plate is horizontally arranged, the vertical plate is vertically arranged as the name implies, in order to ensure that the measurement reference plate 8 marks the posture when measuring the human body, two contact sensors are arranged at one side (the side facing a tester) of the vertical plate, the two contact sensors are arranged at intervals up and down, thereby ensuring that the body can be in parallel contact with the vertical plate, realizing the posture standardization, ensuring the accuracy of the measurement result, connecting the contact sensors with a controller, connecting the controller and the alarm, enabling the tester to touch the contact sensors, controlling the alarm to give an alarm, prompting the worker that the posture of the tester reaches the specified standard; otherwise, if the tester does not touch the contact sensor, the alarm does not give out a buzzing alarm sound to prompt the staff, and the posture of the tester does not reach the specified standard.
