[0046] Furthermore, when the central control module adjusts the tightening force at each fixed point of the first mounting plate, it compares the adjusted tightening force with the preset maximum tightening force. If the adjusted tightening force is less than or equal to the preset maximum tightening force, the central control module determines to use the adjusted tightening force as the installation parameter of the support column; if the adjusted tightening force is greater than the preset maximum tightening force, the central control module determines to use the preset maximum tightening force as the installation parameter of the support column, and uses the first preset tightening force adjustment coefficient to adjust the tightening force at each fixed point of the second mounting plate to the corresponding value.

[0047] Compared with existing technologies, when assembling a single-story staircase component, the assembly status of that floor's staircase is obtained in a timely manner. If the overlap length is too low, it is determined that the installation height of that floor's staircase is too low, resulting in no overlap area. Therefore, the number of first pads is adjusted according to the area of ​​the staircase features and the area of ​​the corresponding feature contour in the preset image information, so as to effectively improve the accuracy of the height of each floor's staircase and thus effectively improve the assembly efficiency of the spiral staircase.

[0048] Furthermore, when the overlap length is low, it is determined that the single-layer stair components are tilted, and the tilt direction is towards the longest side of the fan-shaped staircase. In this case, it is determined whether the actual installation ground of the spiral staircase is tilted, causing the detection module to deviate. Therefore, the sum of the tilt angles obtained by the first level and the second level, i.e., the tilt degree, is calculated. When the tilt degree is extremely small, it is determined that the detection module is accurate. Therefore, the number of second shims is adjusted to keep the spiral staircase horizontal, so as to effectively improve the accuracy of the height of each floor of the staircase, thereby effectively improving the assembly efficiency of the spiral staircase.

[0049] Furthermore, when the inclination is too large, i.e. when the ground is sloping, the inclination of a single-story staircase is determined based on the proportion of the area of ​​the staircase features to the area of ​​the corresponding feature contour in the preset image information. Based on the inclination, the operating parameters of the hoisting mechanism are determined to meet the preset standards. The central control module adjusts the preset evaluation standard, i.e. the preset area proportion, based on the inclination vector. The specific evaluation standard is determined according to the specific construction situation, so that the hoisting of the spiral staircase can be accurately assembled under various construction conditions, thereby effectively improving the assembly efficiency of the spiral staircase.

[0050] Furthermore, when the overlap length is high, it is determined that the insufficient fixing strength of the mounting plate causes the stair components to tilt in the direction of the fan-shaped arc due to the shift of the center of gravity during the hoisting process. Therefore, the tightening force of each fixing point of the first mounting plate is adjusted, which effectively improves the stability and safety of the spiral staircase, and thus effectively improves the assembly efficiency of the spiral staircase.

[0061] S2, when the hoisting mechanism completes the hoisting of the single-layer stair components, the central control module obtains the stair features of the single-layer stair components in the image information based on the image information of each layer of stair components that have been hoisted, and determines whether the operating parameters of the hoisting mechanism meet the preset standards based on the overlap length between the outline of the stair features and the outline of each feature in the preset image information.

[0062] S3, when the central control module determines that the operating parameters of the hoisting mechanism do not meet the preset standard, the hoisting quantity of the first pad is adjusted to the corresponding value according to the difference between the area of ​​the obtained stair feature and the area of ​​the corresponding feature contour in the preset image information.

[0063] S4, when the central control module initially determines that the operating parameters of the hoisting mechanism do not meet the preset standard, a second determination is made on whether the operating parameters of the hoisting mechanism meet the preset standard based on the ground inclination.

[0064] S5, when it is initially determined that the operating parameters of the hoisting mechanism meet the preset standards, it is determined whether to adjust the number of second pads to the corresponding value based on the proportion of the area of ​​the stair feature to the area of ​​the corresponding feature contour in the preset image information.

[0066] S7, the central control module controls the hoisting mechanism to assemble the stair components and shims layer by layer, and fixes the second mounting plate to complete the assembly of the spiral staircase.

[0067] Specifically, when the hoisting mechanism completes the hoisting of a single-story stair component, the detection mechanism placed on one side of the support column acquires image information of each hoisted stair component. The central control module acquires the stair features of the single-story stair component in the image information. The central control module compares the image information with preset image information to obtain the overlap length between the stair feature contour and the feature contour in the preset image information. Based on the obtained overlap length, the central control module determines whether the operating parameters of the hoisting mechanism meet the preset standard assembly judgment method, wherein:

[0068] The first assembly determination method is that the central control module determines that the operating parameters of the hoisting mechanism do not meet the preset standard, and adjusts the number of hoisting first pads to the corresponding value according to the difference between the area of ​​the obtained stair feature and the area of ​​the corresponding feature contour in the preset image information; the first assembly determination method satisfies that the overlap length is less than or equal to the first preset overlap length.

[0069] The second assembly determination method is that the central control module initially determines that the operating parameters of the hoisting mechanism do not meet the preset standard, and determines whether the operating parameters of the hoisting mechanism meet the preset standard based on the ground inclination; the second assembly determination method satisfies that the overlap length is less than or equal to the second preset overlap length and greater than the first preset overlap length.

[0070] The third assembly determination method is that the central control module initially determines that the operating parameters of the hoisting mechanism meet the preset standards, and adjusts the tightening force of each fixed point of the first mounting plate to the corresponding value according to the difference between the third preset overlap length and the overlap length; the third assembly determination method satisfies that the overlap length is less than or equal to the third preset overlap length and greater than the second preset overlap length.

[0071] The fourth assembly determination method is that the central control module determines that the operating parameters of the hoisting mechanism meet the preset standards and controls the hoisting mechanism to maintain the current operating parameters; the fourth assembly determination method satisfies that the overlap length is greater than the third preset overlap length.

[0072] When assembling a single-story staircase component, the assembly status of that floor is obtained in a timely manner. If the overlap length is too low, it is determined that the installation height of that floor is too low, resulting in no overlap area. Therefore, the number of first pads is adjusted according to the area of ​​the staircase feature and the area of ​​the corresponding feature contour in the preset image information, so as to effectively improve the accuracy of the height of each floor of the staircase and thus effectively improve the assembly efficiency of the spiral staircase.

[0073] Specifically, under the second assembly judgment method, the central control module calculates the sum of the absolute values ​​of the detection results of the first and second level instruments and records it as the tilt angle. Based on the calculated tilt angle, the central control module determines whether the operating parameters of the hoisting mechanism meet the preset standard of the secondary assembly judgment method, wherein:

[0074] The first assembly secondary judgment method is that the central control module determines that the operating parameters of the hoisting mechanism do not meet the preset standard, and adjusts the number of second shims to the corresponding value according to the difference between the second preset overlap length and the overlap length; the first assembly secondary judgment method satisfies that the inclination is less than or equal to the preset inclination.

[0075] The second assembly secondary judgment method is that the central control module initially determines that the operating parameters of the hoisting mechanism meet the preset standards, and judges whether the operating parameters of the hoisting mechanism meet the preset standards based on the proportion of the area of ​​the stair feature to the area of ​​the corresponding feature contour in the preset image information; the second assembly secondary judgment method satisfies that the inclination is greater than the preset inclination.

[0076] The detection mechanism includes a first level and a second level set vertically to obtain the ground inclination, and an image detector to obtain image information of each floor's stair components after hoisting.

[0077] When the overlap length is low, it is determined that the single-layer staircase component is tilted, and the tilt direction is towards the longest side of the fan-shaped staircase. In this case, it is determined whether the actual installation ground of the spiral staircase is tilted, which causes the detection module to deviate. Therefore, the sum of the tilt angles obtained by the first level and the second level, i.e., the tilt degree, is calculated. When the tilt degree is extremely small, it is determined that the detection module is accurate. Therefore, the number of second shims is adjusted to keep the spiral staircase level, so as to effectively improve the accuracy of the height of each floor of the staircase, thereby effectively improving the assembly efficiency of the spiral staircase.

[0078] Specifically, under the second assembly secondary judgment method, the central control module draws a rectangular coordinate system based on the first and second levels, and draws a tilt vector relative to the ground based on the detection results of the first and second levels. The central control module determines a standard adjustment method for the preset area ratio based on the vector length of the obtained tilt vector, wherein:

[0081] The third standard adjustment method is that the central control module uses a third preset standard adjustment coefficient to adjust the preset area to the corresponding value; the third standard adjustment method satisfies that the vector length is greater than the second preset vector length.

[0082] Specifically, the central control module, under the second assembly secondary judgment method, determines whether the operating parameters of the hoisting mechanism meet the preset standard assembly tertiary judgment method based on the proportion of the area of ​​the staircase features to the area of ​​the corresponding feature contour in the preset image information, wherein:

[0084] The second assembly three-stage judgment method is that the central control module determines that the operating parameters of the hoisting mechanism do not meet the preset standard, and adjusts the number of second shims to the corresponding value according to the difference between the area ratio and the preset area ratio; the second assembly three-stage judgment method satisfies that the area ratio is greater than the preset area ratio.

[0085] When the inclination is too large, i.e. when the ground is sloping, the inclination of a single-story staircase is determined by the proportion of the area of ​​the staircase features to the area of ​​the corresponding feature contour in the preset image information. Based on the inclination, the operating parameters of the hoisting mechanism are determined to meet the preset standards. The central control module adjusts the preset evaluation standard, i.e. the preset area proportion, according to the inclination vector. The specific evaluation standard is determined according to the specific construction conditions, so that the hoisting of the spiral staircase can be accurately assembled under various construction conditions, thereby effectively improving the assembly efficiency of the spiral staircase.

[0086] Specifically, the central control module calculates the difference between the area of ​​the staircase feature and the area of ​​the corresponding feature contour in the preset image information under the first assembly determination method, and records this difference as the feature difference. The central control module adjusts the shim method for the number of first shims to be hoisted based on the obtained feature difference, wherein:

[0089] The third shim adjustment method is that the central control module uses a third preset shim adjustment coefficient to adjust the number of first shims to the corresponding value; the third shim adjustment method satisfies that the feature difference is greater than the second preset feature difference.

[0090] Specifically, the central control module calculates the difference between the third preset overlap length and the overlap length under the third assembly determination method, and records this difference as the overlap difference. The central control module determines the adjustment method of the tightening force for each fixing point of the first mounting plate based on the obtained overlap difference, wherein:

If the adjusted tightening force is less than or equal to the preset maximum tightening force, the central control module determines to use the adjusted tightening force as the installation parameter of the support column.
