Guidelines for the design of control centresErgonomic principles for the design of control centresPart 3:Hand reach and zones of controlDL/575.3--1999
This standard specifies the hand reach for sitting and standing positions in the control room (or dispatching room) and the division of operating zones in the layout of controllers, and gives the dimensions of the controller.
This standard does not include the hand and range of other operations or postures that are not directly related to monitoring operations. This standard applies to the design of the instrument panel on the neutral screen and console of various control rooms and dispatching rooms, as well as the layout design of the controller. Note: The hand function reachability of this standard refers to the "hand grasping and pinching function reachability", see Appendix A A2 for details. 2 Reference standards
The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards will be revised, and the parties using this standard should explore the possibility of using the latest version of the following standards. DL/T575.1-1999 Guidelines for Ergonomic Design of Control Centers Part 1: Terms and Definitions DL/T575.8-1999 Guidelines for Ergonomic Design of Control Centers Part 8: Layout and Dimensions of Workstations 3 Definitions
The definitions adopted in this standard are shown in DL/T575.11999. 4 Functional reach of hand in sitting position and division of operation area 4.1 Functional reach of hand in sitting position in the plane above the console table, the functional reach of hand depends on the arm length. When the joint is 180° and the center of the joint is the rotation center, the side view of the arm moving up and down in the sitting position in the plane is shown in Figure 1. 4.1.1 Functional reach size in sitting position
The functional reach size of hand (grasping and pinching) in the plane (grasping the controller with three fingers) is determined by the 5th percentile human body template. If there is no active human body template, it can be determined approximately by graphical method, as shown in Figure 2. Here, the arm system is simplified into a rod system. In Figure 2:
Sitting shoulder joint center height (relative to the seat surface): 530mm; torso line distance from the front edge of the console table: 100mm; arm (hand) maximum functional rotation radius ra: 610mm; forearm (hand) maximum functional rotation radius rtA: 350mm4.1.2 Extension of the functional reach range in sitting position When the torso bends forward, the shoulder joint center moves forward, and the fifth quantile male functional reach range can be extended forward by 150mm~Approved by the State Economic and Trade Commission of the People's Republic of China on February 24, 2000 1246

Figure 2 Dimensions of reach of hand in sitting position in sagittal plane4.2.1.1 If there is no active human body template, the reach of hand in upright sitting position in horizontal plane can be determined approximately by graphical method. Figure 3 is a top view of Figure 2. In the figure:
Distance between shoulder joint centers: 325mm (i.e., the distance between SDPR and SDPL); EDPM: Center of elbow joint in the horizontal plane of shoulder joint, located on the midsagittal plane; EDP'M: Center of elbow joint in the midsagittal plane when the hand is on the console table. 4.2.1.2 The reach of hand in the horizontal plane of shoulder joint is shown by the dotted line in Figure 3. It is formed by connecting the arc with EDPM as the center and rtA as the radius and the arc with SDP or SDP. as the center and as the radius at the tangent point. The rotation angle of the upper arm is from 36° inside the arm to 106° outside the arm.
4.2.1.3 The reachable range of the hand function on the console table, as shown by the solid line in Figure 3. It is formed by connecting the arc with EDPM as the center and ux as the radius and the arc with SDP or SDPL as the center and as the radius at the tangent point. The r and ruA of the reachable range of the hand function on the console table depend on the height difference h between the console and the chair surface, and its value can be calculated from Figure 2. The reference surface height of the recommended seat is 420mm (see A2.5 in DL/T575.81999). For the console table height of 770mm or 700mm, the dimensions of r and ru are as shown in Table 1. Table 1 Calculation values ​​of tt and ua

4.2.2 Extension of functional reach range in sitting posture
Height difference between seat surface and table surface
When the lower body of a person is bent forward, left or right for a short time, the functional reach range of the hand can be extended within a certain range. The functional reach range of the hand extended in the horizontal plane can be approximately expressed by Figure 4 (only the right half is shown). The functional reach range of the hand extended in the horizontal plane with SDPk as the radius and rotating around SDPk and extending in the straight arm state is: the envelope of the circle drawn around SDPE when SDPRe is 150mm~200mm. Among them, the dotted line is the maximum functional reach range of the hand extended in the horizontal plane of the shoulder joint; the solid line is the maximum functional reach range of the hand extended on the console table. It can be seen from Figure 4: In the horizontal plane of the shoulder joint: rar=ra+(150mm~200mm) Console table: rAE=rA+(150mm~200 mm) 4.3 Division of sitting hand operation area on the console table The hand operation area in the horizontal plane can be divided into three parts: comfortable operation area (I), effective operation area (Ⅱ), and extended operation area (V). Generally, when operating in a sitting position, the operation area on the console table is divided as shown in Figure 5 (the height difference between the seat and the table is 260mm). Considering that the hand function reachable range on the console table is affected by the height difference between the table and the chair, 4.1 and 4.2, accurately calculate the range of the operation area.
4.3.1 Comfortable operation area ()
The comfortable operation area is the range covered by the upper arm close to the body, bent elbow, and the forearm extended for rotation.
The comfortable operation area is also called the normal operation area.
4.3.2 Effective operation area (surface)
In the upright sitting state, with the arm straight, the operation area that the hand can reach is called the effective operation area, and its range is equivalent to the hand function and range.
4.3.3 Extended operation area (V)
In the sitting state, the operation area that the hand can reach when the body changes its posture is called the extended operation area. Its range is equivalent to the extended hand function reachable range.
4.4 Division of hand operation area in the sagittal plane
Division of hand operation area in the sagittal plane (according to the 5th percentile male size) is shown in Figure 6. 4.4.1 Comfortable operation area ()
The space between the height of the center of the sitting shoulder joint and the tabletop within the reach of hand function. 4.4.2 Accurate operation area (1)
The space between the height of the sitting eye and the tabletop within the reach of hand function. 4.4.3 Effective operation area (III)
The space above the eye height and within the reach of hand function. 4.4.4 Extended operation area (IV)
In the sitting position, the human body leans forward, the center of the shoulder joint moves forward 150mm~~200mm, and the reach of hand function can be extended forward, 1248

5 Standing hand functional reach and vertical screen operation area division 5.1 Standing hand functional reach in sagittal plane 5.1.1 Standing hand functional reach size
Standing hand functional reach size in sagittal plane can generally be determined by the 5th percentile male human body template: If there is no active human template, it can also be determined approximately by the drawing method. The specific dimensions are as follows: a) Standing shoulder joint center height: 1270mm; b) Arm (hand) maximum functional rotation radius: ra=610mm. 5.1.2 The upper and lower limits of the maximum functional height that can be reached by both hands in front of a vertical screen When the operator stands in front of a vertical screen (see Figure 7, the toe of the shoe is about 150mm away from the screen), the upper and lower limits of the maximum functional height that can be reached by both hands are as follows: a) Upper limit: 1790mm (based on the 5th percentile male with both hands extended); b) Lower limit: 840mm (based on the 95th percentile male with both hands lowered). 315

Standing hand function range in sagittal plane (nm) R610
The division of standing (in sagittal plane) operation area needs to comprehensively consider the human body structure size, human visual field, effective range of human limbs, most suitable range of limbs, operation speed and accuracy requirements, etc. For standing operation represented by vertical screens and cabinets, the standing hand operation area can be divided into three parts: comfortable operation area, precise operation area, and effective operation area, as shown in Figure 8. 5.2.1 Comfortable operation area
The comfortable operation area is the space range between the standing shoulder height and the standing elbow height. Within this range, the muscle activity level and energy metabolism rate are the lowest. The size of the comfortable operation area is determined by the size of the 50th percentile man (plus 25mm heel height), and its size range is 1400mm~1050mm.
5.2.2 Precision operation area
The precision operation area is also the most important display area for working in front of the vertical screen. Its size is determined by the following factors:
a) Based on the size of the 50th percentile man (plus 25mm heel height)06.

b) Set the distance between the eye and the vertical screen surface to 400mm, comprehensively consider the observation distance between the suit and the vertical screen and the feasibility of hand operation; c) The upper limit of the precision operation area size is determined by 15° above the horizontal line of sight; the lower limit is determined by 30° below the horizontal line of sight. Its size range is 1690mm1350mm.
5.2.3 Effective operating area
5.2.3.1 Upper limit size
The upper limit of the maximum functional reach of both hands in front of the vertical screen (see 5.1.2) is used as the upper limit size of the effective operating height, which is 1 790 mm. bzxZ.net
5.2.3.2 Lower limit size
The elbow height of the 95th percentile man in a single-legged vulnerable position is used as the lower limit size of the effective operating height, which is 650 mm. 1250
A1 Principles of controller location layout
DL/T575.3-1999
Appendix A
(Suggestive appendix)
Application instructions
When the number of controllers is small, the controllers should be arranged at the best position in the comfortable operating area. When the number of controllers is large, the layout priority issue should be considered. The priority of controller layout location should generally consider: frequency of use principle, importance principle, and logic of use principle, and the priority of arrangement should be comprehensively considered. A1.1 Frequency of use principle
The priority of controller layout location should be considered according to the frequency of use. The controller with the highest frequency of use should be placed in the position closest to the operator; the controller with high frequency of use should be placed in the comfortable operation area; the controller with low frequency of use should be placed towards the edge in turn, and set in the effective operation area and the extended operation area. A1.2 Importance principle
Some important controllers that require fine operation should be placed in the precise operation area, and the setting position should consider the clarity and accuracy of the controlled signal. Secondary controllers are placed in the effective operation area and the extended operation area in turn. Emergency controllers involve the safety of system operation and should also be placed in the comfortable operation area or the precise operation area. A1.3 Logic of use principle
In the layout of controllers, considering the safety and efficiency of the system, they are generally arranged with the display according to a certain logic of use. For example. Arrange by function, order of use or operation procedure. Although the controllers in a group conform to the logic of use, there may be large differences in the frequency of use or importance.
In actual application, the above three principles should be considered comprehensively according to the specific situation. A2 Three types of hand reach range
The hand reach range is related to the hand grasping state: a) Hand (middle finger) reach range: the spatial range that can be touched by the middle finger tip; b) Hand pinch (function) reach range: the range reached by the grasping center of the three fingers (thumb, index finger, middle finger) of the hand in the pinching state. This is the most commonly used hand operation method for the control room system. The functional reach range of this standard adopts the "three-finger pinch" state. c) Hand grip axis (function) reach range: the spatial range reached by the axis center in the hand grip axis state. Note: According to the analysis of the measurement values ​​provided by some data, the maximum size of the hand gripping reach range is approximately between the maximum size of the hand reach range and the maximum size of the hand grip axis reach range.
A3 Instructions for the use of each parameter value
The various parameter values ​​given in this standard for the hand functional reach and hand operation area division are measured statistical values ​​under specific conditions and can be modified according to the actual situation and the characteristics of the user group during use. Appendix B
