Description

Technical Field

[0001] The invention relates to a method for spatial layout of equipment, and in particular to a method for spatial layout of marine engineering internal operating equipment based on ergonomics. Background Art

[0002] Inside the marine engineering module, the layout of the operating equipment directly affects the operating efficiency of the operators. Therefore, a reasonable spatial layout of the operating equipment is crucial to improving the efficiency of marine engineering operations. However, at present, most equipment is not fully considered when installing the operator, resulting in the operator being in an uncomfortable state for a long time and unable to quickly reach the operating position. This not only increases the risk of equipment misoperation during work, but also fails to improve work efficiency. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a spatial layout method for marine internal operating equipment based on ergonomics. The method can determine the installation position of the operating equipment through human body related data, etc., to improve the comfort and work efficiency of the staff in operating the equipment.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A spatial layout method of marine internal operating equipment based on ergonomics of the present invention comprises the following steps:

[0006] Step 1: Establish a spatial coordinate system OXYZ inside the room where the operating equipment is to be installed;

[0007] Step 2: Record the data of the equipment to be installed;

[0008] Step 3: Simplify the operating equipment to be installed into a rectangular parallelepiped model, and use the center position of the rectangular parallelepiped to represent the installation position of the operating equipment to be installed;

[0009] Step 4: determine the range of the shortest distance and the farthest distance of each facility in the installation space from the origin O in the X-axis, Y-axis, and Z-axis directions of the spatial coordinate system OXYZ;

[0010] Step 5: Determine the adjustment distance Δz in the Z direction of the operating equipment to be installed based on the human body data of the staff;

[0011] Step 6. Adjust the distances of the equipment to be installed in the X and Y directions according to the adjustment distance kΔx in the X direction and the adjustment distance sΔy in the Y direction, and determine whether the adjusted equipment to be installed collides with the existing facilities. If a collision occurs, do not record this installation position, recalculate the adjustment distance kΔx in the X direction and the adjustment distance sΔy in the Y direction. If there is no collision with the existing facilities, determine this position as a reasonable installation position for the equipment to be installed, and record the coordinate value (x, y, z) of this installation position, where Δx is the adjustment step in the X direction, Δy is the adjustment step in the Y direction, k is the adjustment coefficient of the adjustment distance in the X direction, and s is the adjustment coefficient of the adjustment distance in the Y direction. Change the adjustment distances kΔx and sΔy by changing the values ​​of k and s. The specific method is as follows:

[0012] Step 1: kΔx is the adjustment distance in the X direction, sΔy is the adjustment distance in the Y direction, and Δz is the adjustment amount in the Z direction calculated in step 5;

[0013] Step 2: Set initial k = 0;

[0014] Step 3: Determine the relationship between k and N1. If k≤N1, set s=0 and proceed to step 4. If k>N1, proceed to step 7, where

[0015] Step 4: Determine the relationship between s and N2. If s≤N2, proceed to step 5. If s>N2, set k=k+1 and return to step 3.

[0016] Step 5: Let the installation position of the device to be installed, that is, the center of the rectangular model, be (x, y, z). Since the adjustment distance of the device to be installed in the X direction is kΔx, the adjustment distance in the Y direction is sΔy, and the adjustment distance in the Z direction is Δz, The range interval set of the installation equipment in the X, Y, and Z directions is X1 = [kΔx, x1+kx], Y1 = [sΔy, y1+sΔy], Z1 = [Δz, z1+Δz], and whether the equipment to be installed collides with the existing facilities is determined. Traverse i = 1, 2, ..., n. If and and If the installation position is reasonable, record the installation position (x, y, z) this time; otherwise, do not record;

[0017] Step 6: Set s=s+1 and return to step 4;

[0018] Step 7: Number the recorded installation positions from 1 to q, and the reasonable installation position recorded for the tth time is recorded as O. t (x t ,y t , z t), t=1, 2, …, q;

[0019] Step 7: Install the equipment to be installed at a reasonable installation location.

[0020] The beneficial effects of the present invention are:

[0021] The present invention uses the human body data of the staff as a reference, realizes the reasonable layout of the spatial position of the operating equipment, and improves the comfort and work efficiency of the staff in operating the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] As shown in the accompanying drawings, a spatial layout method of marine internal operation equipment based on ergonomics of the present invention includes the following steps:

[0034] Step 1: Establish a spatial coordinate system OXYZ inside the room where the operating equipment is to be installed. The specific steps can be:

[0035] Select the intersection of the ground plane and the corner of the room as the origin O, select the direction parallel to the wall of the room on the ground plane as the X-axis direction, select the direction perpendicular to the X-axis on the same plane as the Y-axis direction, select the direction perpendicular to the X-axis, Y-axis and perpendicular to the ground plane upward as the Z-axis direction, and the room space where the operating equipment is to be installed as the installation space. Determine the range of the space to be installed from 0 to x0 in the X direction, 0 to y0 in the Y direction, and 0 to z0 in the Z direction, as shown in the attached figure. Figure 2 As shown;

[0036] Step 2, record the data of the operating equipment to be installed, the data may include the user posture p of the operating equipment, if the equipment needs to be used in a standing position, the user posture p=1; if the equipment needs to be used in a sitting position, the user posture p=0, the distances of the operating equipment in the X direction, Y direction, and Z direction in the OXYZ coordinate system in the working posture are recorded as x1, y1, and z1 respectively, the lowest height z2 and the highest height z3 of the operating surface of the equipment operating table from the ground plane, and the equipment leg height z4, the equipment leg height refers to the height of the leg space reserved by the equipment for the sitting user; when p=1, z4=0, when p=0, z4 is the actual measured height;

[0037] Step 3: Simplify the operating equipment to be installed into a rectangular parallelepiped model, and use the center position of the rectangular parallelepiped to represent the installation position of the operating equipment to be installed;

[0038] As an implementation mode of the present invention, the specific process of this step is: the operating device is set at the origin, and a rectangular parallelepiped model is established with the distances x1, y1, and z1 of the operating device in the X direction, Y direction, and Z direction as the length, width, and height of the rectangular parallelepiped to simplify the operating device to be installed. The coordinates of the vertices of the simplified rectangular parallelepiped operating device in the OXYZ coordinate system are respectively (0, 0, 0), (0, x1, 0), (0, y1, 0), (x1, y1, 0), (0, 0, z1), (0, x1, z1), (0, y1, z1), and (x1, y1, z1). The center position O0 of the rectangular parallelepiped is The movement of the center position O0 of the cuboid in each direction is the same as the movement of the operating device in each direction, and the center position of the cuboid represents the installation position of the operating device;

[0039] Step 4: Determine the range of the closest distance and the farthest distance of each facility in the installation space from the origin O in the X-axis, Y-axis, and Z-axis directions of the spatial coordinate system OXYZ. The specific method is: number the existing facilities in the site from 1 to n, and determine the closest distance x of the existing facilities from the origin O along the X, Y, and Z directions. 1i ,y 1i 、z 1i and the maximum distance x 2i ,y 2i 、z 2i , then the range interval sets of each existing facility in the installation space in the X, Y, and Z directions are X 1i =[x 1i , x 2i ],Y 1i =[y 1i ,y 2i ],Z 1i =[z 1i , z 2i ], i = 1, 2, ..., n;

[0040] Step 5: Based on the human body data of the staff, determine the Z-direction adjustment distance Δz of the operating equipment to be installed. The specific method is as follows:

[0041] The first step is to measure the human body data of all m staff members, including the standing shoulder height a of each person. j , standing elbow height b j , Sitting shoulder height c j , Sitting elbow height d j , Sitting Thigh High j , j = 1, 2, ..., m, the schematic diagram of the standing human body data measurement is as follows Figure 4 As shown in the figure, the schematic diagram of sitting human body data measurement is as follows Figure 5 As shown, the maximum sitting thigh height among all people is recorded as e max The sitting thigh height is the height of the upper surface of the thigh from the ground when the staff is sitting, and the standing shoulder height is calculated separately. j The average Standing elbow height b j The average Sitting shoulder height c j The average and sitting elbow height d j The average Average standing shoulder height The calculation formula is as follows:

[0042]

[0043] The same can be said

[0044] Step 2: Determine the optimal working range set of the operating equipment to be installed in the Z direction in the standing position The optimal working range of the operating equipment to be installed in the Z direction in the sitting position The Z-direction operating range interval set of the equipment operating table is Z3 = [z2, z3], and the minimum comfortable height of the legs in the sitting position is Z4, Z4 = e max +h, h is the margin of activity of the leg, generally 20mm;

[0045] Step 3: When p = 1, determine the relationship between the optimal working range Z1 in the standing position and the operating range Z3 of the equipment operating table. When |Z1| ≥ |Z3|, determine the relationship between the lower limits of the Z1 and Z3 intervals. If As attached Figure 6 As shown, there are two cases. In the first case, if the optimal working range in the standing position and the operating range of the equipment operating table have overlapped, no adjustment is required. In the second case, if the equipment needs to be adjusted downward as a whole, but the equipment as a whole cannot be lowered, no adjustment is required. In summary, the adjustment distance Δz of the equipment operating table is 0. As attached Figure 7 As shown, the adjustment distance of the equipment operating table

[0046] When |Z1|<|Z3|, determine the relationship between the upper limits of the intervals Z1 and Z3. If As attached Figure 8 As shown, there are two cases. In the first case, the optimal working range interval in the standing position and the operating range of the equipment operating table have overlapped, so no adjustment is required. In the second case, the optimal working range interval in the standing position and the operating range of the equipment operating table do not overlap, and the equipment needs to be adjusted downward as a whole. However, since the equipment as a whole cannot be lowered, no adjustment is required. In summary, the adjustment distance Δz of the equipment operating table is 0; if As attached Fig. 9 As shown, the adjustment distance of the equipment operating table

[0047] The fourth step, when p = 0, first determine the relationship between the minimum comfortable height of the legs in the sitting position Z4 and the leg height of the equipment z4. When Z4 ≤ z4, the first adjustment distance Δz' = 0. When Z4 > z4, the first adjustment distance Δz' = Z4-z4. Let the operating range of the equipment operating table after the first adjustment be Z3' = [z2+Δz', z3+z']; then determine the relationship between the optimal working range interval Z2 in the sitting position and the operating range of the equipment operating table after the first adjustment Z3'. When |Z2| ≥ |Z3'|, determine the relationship between the lower limit of the interval Z2 and Z3'. If Then adjust the distance Δz = Δz', if Adjust the distance When |Z2|<|Z3'|, determine the relationship between the upper limits of the interval Z2 and Z3'. If Then adjust the distance Δz = Δz', if Adjust the distance

[0048] Step 5: Verify whether the adjustment distance Δz in the Z direction calculated in steps 3 and 4 is reasonable, that is, whether the device to be installed is within the installation space after adjustment of z, and compare z1+Δz with z0. If z1+Δz≤z0, the value of Δz remains unchanged. If z1+Δz>z0, the adjustment distance Δz is updated to z0-z1.

[0049] Step 6. Adjust the distances of the equipment to be installed in the X and Y directions according to the adjustment distance kΔx in the X direction and the adjustment distance sΔy in the Y direction, and determine whether the adjusted equipment to be installed collides with the existing facilities. If a collision occurs, do not record this installation position, recalculate the adjustment distance kΔx in the X direction and the adjustment distance sΔy in the Y direction. If there is no collision with the existing facilities, determine this position as a reasonable installation position for the equipment to be installed, and record the coordinate value (x, y, z) of this installation position, where Δx is the adjustment step in the X direction, Δy is the adjustment step in the Y direction, k is the adjustment coefficient of the adjustment distance in the X direction, and s is the adjustment coefficient of the adjustment distance in the Y direction. Change the adjustment distances kΔx and sΔy by changing the values ​​of k and s. The specific method is as follows:

[0050] Step 1: kΔx is the adjustment distance in the X direction, sΔy is the adjustment distance in the Y direction, and Δz is the adjustment amount in the Z direction calculated in step 5;

[0051] Step 2: Set initial k = 0;

[0052] Step 3: Determine the relationship between k and N1. If k≤N1, set s=0 and proceed to step 4. If k>N1, proceed to step 7, where

[0053] Step 4: Determine the relationship between s and N2. If s≤N2, proceed to step 5. If s>N2, set k=k+1 and return to step 3.

[0054] Step 5: Let the installation position of the device to be installed, that is, the center of the rectangular model, be (x, y, z). Since the adjustment distance of the device to be installed in the X direction is kΔx, the adjustment distance in the Y direction is sy, and the adjustment distance in the Z direction is Δz, The range interval set of the installation equipment in the X, Y, and Z directions is X1 = [kΔx, x1 + kΔx], Y1 = [sΔy, y1 + sΔy], Z1 = [Δz, z1 + Δz], and whether the equipment to be installed collides with the existing facilities is determined. Traverse i = 1, 2, ..., n. If and and If the installation position is reasonable, record the installation position (x, y, z) this time; otherwise, do not record;

[0055] Step 6: Set s=s+1 and return to step 4;

[0056] Step 7: Number the recorded installation positions from 1 to q, and the reasonable installation position recorded for the tth time is recorded as O. t (x t ,y t , z t ), t=1, 2, …, q;

[0057] Further preferably, in order to facilitate the staff to quickly reach the equipment to be installed, the present invention also includes a step of optimizing the reasonable installation position obtained in step 6, and the specific process is as follows:

[0058] Step 1: Determine the center position of the entrance of the installation space channel as (X0, Y0, Z0), and calculate the horizontal distance ΔD between the center of the channel entrance and the reasonable installation position t , t=1, 2, ..., q, t represents the tth record in step 6 and step 7;

[0059] Step 2: Compare ΔD t The size of ΔD t The minimum installation position is the final installation position, and the center coordinates of the final installation position are (u, v, w);

[0060] Step 7: Install the equipment to be installed at a reasonable installation position. The equipment to be installed is simplified by a rectangular parallelepiped model, and the center of the rectangular parallelepiped replaces the installation position. Therefore, the equipment to be installed should be installed at (x t ,y t , z t ) as the center, In a cuboid with vertices as the center, first draw a circle on the ground plane with The device to be installed is moved to the rectangle with the vertices thereof, and the device is adjusted to be completely within the rectangle. If the Z direction needs to be adjusted, the device is moved upward as a whole according to Δz. Preferably, the device can be adjusted upward as a whole by raising the height.

[0063] As a preferred method, the equipment to be installed is finally installed on a plane centered on (u, v, w). In a cuboid with vertices as the center, first draw a circle on the ground plane with Move the equipment to be installed to the rectangle with the vertices as the vertices and adjust the equipment to be completely inside the rectangle. Then, adjust the overall upward movement of the equipment by Δz by raising it.
