[0079] Installation judgment unit: used to judge the installation progress of the steel mesh according to the data collection position; when the present invention is performing data collection, if the tensioning wheel generates data, it means that the steel mesh has moved above the installation position to achieve fine-tuning. If only the lifting device is driven, left movement or right movement means that the steel mesh is lifted or the lifting is completed.
[0080] Automatic control module: used to control the transmission control system to install the steel mesh according to the installation progress, structural control data, and a preset steel mesh installation process template. During automatic control, the present invention and the steel mesh installation process template are provided to determine the steel mesh installation steps and the data that should be generated at a certain installation step. Then, based on the installation progress, the subsequent steps are determined, and the steel mesh is controlled to be installed through the subsequent steps.
[0081] The beneficial effect of the present invention is that the present invention can realize the collection of data of the steel mesh during the installation process, and then the installation progress can be judged by these data, and then the automatic control installation of the steel mesh can be realized according to the installation progress, thereby realizing unmanned operation.

It is a structural component used to determine the generated data, such as the tensioner, etc. The ratio of the standard installation parameters that should be achieved and the actual collected data under the standard execution, P i Indicates execution parameters, which is equivalent to the present invention judging the installation status by the sum of the actual execution parameters of the device and the execution parameters stored in the system. This can be used to determine whether the actual execution status exceeds the preset installation progress or does not exceed the preset installation status, thereby determining the installation status.
[0094] Step 2: Build an installation parameter setting model based on the preset installation parameter data:
[0095]
[0096] Among them, W j represents the jth system structure position parameter; δ j represents the control parameters of the j-th system structure; Q j The order parameter representing the control order of the j-th system structure; t j represents the control time of the jth system structure; γ represents the composition coefficient of the system structure; S (j) represents the jth system structure distribution coefficient; j = 1, 2, 3...m; m represents the total number of system structures;
[0097] In step 2, the present invention can determine the execution parameters of each system structure under ideal conditions by constructing a setting model of the installation parameters, and introduces the execution time and execution order of each device, and then determines the installation parameters of the execution devices of each system structure under actual conditions in a differential form.

[0099]
[0100] Among them, E represents the progress value of the construction progress.
[0101] In step 3, the present invention calculates an execution coefficient by comparing the model of the actual installation parameters and the execution parameters of each device, that is, by comparing the installation parameters and the actual execution parameters, and then determines the execution progress corresponding to each execution coefficient.
[0102] As an embodiment of the present invention: the hoisting control module includes:
[0103] Transverse control unit: used to control the transverse movement of the lifting device by driving the motor and the lead screw when the lifting device is lifting a steel mesh or after the lifted steel mesh is installed; transverse control is to control the lifting device to achieve left and right movement. At this time, there are only two situations: at the beginning of installation or after installation, the lifting device goes to lift another steel mesh.

When controlling the up and down movement of the steel mesh, the present invention uses a hydraulic device to control the descent and ascent of the lifting device to achieve the installation of the steel mesh.
[0112] As an embodiment of the present invention, the tensioning control module includes:
[0113] Tensioning wheel control unit: used to determine the difference between the steel mesh and the installation position based on the laser calibration device on the tensioning device, and fine-tune the position of the steel mesh based on the difference; when there is only a small adjustment between the installation position and the actual position of the steel mesh and it can be lowered for installation, the present invention will achieve regulation through the tensioning wheel, and the laser calibration device is set to achieve fine-tuning of the tensioning device.
[0114] Error determination unit: used to obtain the calibration data of the laser calibration device and the real-time position of the steel mesh, and to establish a virtual installation scene, perform installation rehearsal, and determine the difference; when the steel mesh is installed, fine-tuning is performed because there is a small error, and this error is difficult to detect manually, so the present invention uses the laser calibration device to detect this error and make adjustments.

[0149] Among them, when H=1, it means that the steel mesh does not need to be adjusted; when H<1, it means that the steel bars need to be adjusted;
[0150] In step 4, the present invention determines whether the connection is very consistent through the correlation between the installation condition and the limit condition. If it is very consistent, there is no need to adjust the position of the steel mesh. If it is not consistent, the steel mesh needs to be adjusted.
[0151] Step S5: When the steel mesh needs to be adjusted, the installation difference that needs to be adjusted is determined according to the installation-related value, and the position of the steel mesh is adjusted according to the difference.
[0152] As an embodiment of the present invention, the sprocket limiting unit further comprises the following steps for performing emergency limiting:
[0153] Step 10: Determine the real-time alignment angle of the steel mesh according to the steel mesh;
[0154] Step 20: judging whether there is any installation deviation of the steel mesh according to the real-time alignment angle; wherein,
[0155] When there is an installation deviation, the tensioning coefficient of the tensioning wheel and the control coefficient of the real-time alignment angle of the steel mesh are determined, and the tensioning wheel is controlled to continue to adjust;
[0156] When there is no installation deviation, the motor driving the tensioning wheel is controlled to stop rotating to perform emergency limiting.
[0157] During the emergency limiting process, because it is an emergency limiting of the tensioning wheel, the present invention determines whether urgent adjustment is required by way of angle calibration. Since a fast and immediate emergency limiting is to be achieved, the present invention stops the motor to achieve a situation where the tensioning wheel has no moving power. Even if there is inertia, the chain used in the present invention can only be an iron chain. Therefore, even if there is inertia, the toughness of the iron chain can offset the inertia.
[0158] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
