The first instruction is used to lift the climbing formwork to a preset height, for example, the preset height is a layer height, such as 3m (or 4m, or other heights); by using the acceleration sensor to obtain acceleration information and calculate the actual lifting distance, the position of the formwork can be accurately controlled to ensure that it moves to the position accurately according to the predetermined height; the automatic in-place judgment reduces the dependence on manual inspection, reduces labor intensity, and improves construction efficiency; by accurately controlling the lifting of the formwork, the safety risks caused by insufficient lifting or excessive lifting are reduced. In practical applications, the above-mentioned acceleration sensors can also be installed at the four corners of the lower formwork.

[0047] In an optional embodiment, the intelligent control module 12 is also used to perform one of the following operations: when it is determined based on the comparison result that the first set of data meets the first preset condition, the intelligent control module 12 controls the electric hoist 22 to engage the brake to stop lifting the climbing formwork, and issues a first alarm message, wherein the first alarm message is used to indicate that the climbing state of the climbing formwork is abnormal, and the first preset condition includes at least one of the following: the force data is greater than or equal to the first preset value; the horizontality data is greater than or equal to the second preset value; the structural strain data is greater than or equal to the third preset value; a group of preset values ​​includes a first preset value, a second preset value and a third preset value; when it is determined that the climbing formwork has been lifted into place, the intelligent control module 12 stops sending a lifting signal to the electric hoist 22.

[0048] In the above embodiment, the intelligent control module 12 can monitor the force data, levelness data and structural strain data of the climbing formwork in real time, and compare them with the corresponding preset values ​​in a set of preset values. When any data is detected to exceed the preset value, the intelligent control module 12 will immediately control the electric hoist 22 to brake, stop lifting the climbing formwork, and issue a first alarm message, thereby effectively preventing accidents caused by overload, tilt or deformation, and improving construction safety. At the same time, when it is determined that the climbing formwork has been lifted into place, the intelligent control module 12 will automatically stop sending the lifting signal to the electric hoist 22 to ensure accurate control of the climbing process and avoid the risks caused by excessive lifting.

[0049] In this embodiment, the intelligent control module 12 can immediately control the electric hoist 22 to stop lifting and issue a first alarm message when it detects that the force, levelness or structural strain data exceeds the corresponding preset value, thereby improving the response speed and safety to abnormal conditions; for example, the first preset value is 1.1 times (or other multiples) the weight of the climbing formwork, the second preset value is 5‰ (or other values), and the third preset value is 50mm (or other values). And the intelligent control module 12 determines whether the formwork is lifted in place and stops sending the lifting signal, thereby improving the accuracy of the formwork lifting operation and avoiding the problem of over-lifting or under-lifting; the automated abnormal detection and response reduces the need for manual continuous monitoring, reduces labor intensity, and improves construction efficiency; the automated abnormal detection and response reduces the need for manual continuous monitoring, reduces labor intensity, and improves construction efficiency. The lifting signal in this embodiment can be understood as an enable signal for the electric hoist 22. In actual applications, the intelligent control module 12 can send a lifting signal to the electric hoist 22 through the data interaction unit 122, or stop sending a lifting signal to the electric hoist 22.
