After the result is finalized, the application building engine 335 builds the application, enabling the developer to freely define front-end interface components, data source binding methods, data models, business logic, and workflows. The platform automatically generates code based on the combination result, and the developer can also add custom code based on business requirements, providing strong control over the program and thus higher flexibility to design highly customized and complex software.

[0054] In addition, as Figures 6-12As shown, on the basis of the above embodiment, in order to improve the flexibility of the development platform application, the application is also equipped with a plurality of portable operation panels applied to the low-code application development platform, the operation panel includes a main operation screen 4 of a regular polygon and a plurality of sub-operation screens 5 distributed along the edges of the main operation screen 4; the sub-operation screen 5 is provided with an independent data link module, which can link data with the corresponding sub-operation screen 5 of other portable operation panels; the main operation screen 4 is provided with a main data link module, which can link data with the main operation screen 4 of other portable operation panels, and the low-code platform 3 and the application editing and publishing 9; a slide rail 41 is arranged below the main operation screen 4 corresponding to each edge of the main operation screen 4; a slide block 42 is arranged on the slide rail 41; a first connecting rod 43 is hinged at one end of the slide block 42; a second connecting rod 44 is hinged at one end of the first connecting rod 43 and at the other end of the first connecting rod 43, and the other end is hinged on the back of the sub-operation screen 5; a torsion disc 45 is arranged at the hinge of the first connecting rod 43 and the second connecting rod 44; the torsion disc 45 includes an outer ring body 451, an inner ring body 452, and an annular wave-shaped elastic spring piece 453 arranged between the outer ring body 451 and the inner ring body 452; the other end of the first connecting rod 43 is connected with the outer ring body 451 to rotate; the one end of the second connecting rod 44 is connected with the inner ring body 452 to rotate; a supporting pad 454 is arranged at the lower part of the torsion disc 45.

[0055] On the basis of the above, further, the sub-operation screen 5 is a folding screen, and the folding manner is to unfold outward from the front of the sub-operation screen 5 to the left and right sides.

[0056] Further, an interface 46 is arranged on the back of the main operation screen 4; a vertical stand 6 is vertically arranged on the workbench; a joint 61 is sleeved on the vertical stand 6; the joint 61 can be driven to rotate by a first servo motor 8; the joint 61 is integrated with a charging required circuit connector and a data transmission required circuit connector in the interface 46; when operation is needed on the workbench, the interface 46 of the main operation screen 4 is connected with the joint 61, and when in use, the main operation screen 4 can be rotated by a certain angle according to the user's operation control, so that the sub-operation screen 5 needed to be used is in a comfortable position; the main operation screen 4 and the sub-operation screen 5 are respectively provided with a gravity sensing device to make the interface vertical.

[0057] Under normal circumstances, the portable operation panel is like Figure 6 and 9 as shown, folded and located below the main operation screen 4, and the whole can be supported by the supporting pad 454 and used as a normal flat panel; when the display interface and the operation interface need to be expanded, as shown in Figure 7 first, the sub-operation screen 5 is pulled out outward, and then as shown in Figure 8 , 10As shown in Figs. 11, the sub-operation panel 5 is unfolded to the left and right to expand the area, in this embodiment, the main operation panel 4 is a regular hexagon, so when the area of each folded part of the sub-operation panel 5 is exactly half of the main part of the sub-operation panel 5, the maximum unfolded area is reached, and when the two folded parts are folded, the area is exactly the same as the main part, so the maximum folded area is reached, thus achieving a perfect balance between the folded and unfolded areas and the maximum effect; the sub-operation panel 5 can be used to display different modules independently according to the needs of the operator, so that the developer or tester can develop and test in a more flexible situation and environment, and the developers or testers in different stages can view or edit different modules according to their own permissions, such as the visual editing module, so that each sub-operation panel 5 and the main operation panel 4 can be used to display different modules, such as page design and management module, configuration page associated data module, component library, etc.; since the sub-operation panel 5 is provided with an independent data link module, it can link data with other portable operation panels as needed, so only the data in the sub-operation panel 5 can be shared by the personnel who can view or edit the module.

[0058] The storage process of the sub-operation panel 5 is relatively simple, relying on the characteristics of the twist disc 45, and the first connecting rod, the second connecting rod, and the main operation panel 4 and the sub-operation panel 5 form a triangular stable shape with variable angle position but stable static state, combined with the slide rail and slide block design, not only can realize the storage and pull-out of the sub-operation panel 5, and the main operation panel 4 is flush, but also the action is smooth and coherent, the structure is simple, the service life is long, and at the same time it can naturally form a support, thus providing support for the entire operation panel; when the annular wave-shaped elastic spring sheet 453 in the twist disc 45 is squeezed beyond the threshold value, it will deform, so that the outer ring body 451 and the inner ring body 452 can rotate relatively, and when the external force is removed, the deformation of the annular wave-shaped elastic spring sheet 453 recovers, and the threshold value exceeds the gravity of the entire operation panel, and also reserves the pressure when the operation is pressed, so during ordinary placement and operation, the annular wave-shaped elastic spring sheet 453 will not deform and rotate.

[0061] Further, a plurality of hydraulic telescopic rods 712 are uniformly arranged outside the seat body 71. The upper end of the hydraulic telescopic rod 712 is fixed on a structure body 713 below the concave arc screen 73 to drive the cabin body above the seat body 71 and the seat table 72 to lift.

[0062] Further, the development auxiliary cabin is also provided with a gesture control device, which comprises a clicking sleeve 714 sleeved on the index finger and a sensing plate 715 laid on the folding table top of the seat 77; the side of the clicking sleeve 714 facing downward is embedded with a piezoelectric ceramic sheet 716; the piezoelectric ceramic sheet 716 is electrically connected with a first microprocessor; the first microprocessor receives the electric signal of the piezoelectric ceramic sheet 716 and wirelessly sends it to the server; the sensing plate 715 comprises a bottom plate 7151, a plurality of copper coils 7152 embedded in the bottom plate 7151 in a dense matrix arrangement and a second microprocessor; the copper coils 7152 are respectively electrically connected with the second microprocessor; the clicking sleeve 714 is provided with a micro electromagnetic iron 7141; a circuit provides alternating current for the micro electromagnetic iron 7141 at a certain frequency; the further one end of the magnetic pole of the micro electromagnetic iron 7141 faces downward, and the rapid change magnetic field generated thereby passes through the copper coils 7152 to make the copper coils 7152 generate induced electromotive force, and further generate induced current which is received and analyzed by the second microprocessor; the second microprocessor compares the electric signals of the copper coils 7152 received at the same time, and wirelessly sends the coordinates of the copper coil 7152 with the strongest electric signal to the server in real time.

[0063] The use method of the development auxiliary cabin comprises the following steps:

[0064] ①The user sits on the seat 77, and the hydraulic telescopic rod 712 is lowered and shortened to make the development auxiliary cabin body downwardly sleeve on the seat table 72;

[0065] ②The user can choose to synchronously operate the development platform system through the operation panel 71 or to operate through the gesture control device; when the gesture control device is used, the clicking sleeve 714 is sleeved on the index finger, and a sleeve integrated with a battery, a micro inverter and a first microprocessor is worn on the wrist;

[0066] ③The battery supplies power to the micro electromagnetic iron 7141 through the micro inverter at a set frequency. The micro electromagnetic iron 7141 generates an alternating magnetic field under the action of alternating current. Since one end of the micro electromagnetic iron 7141 is downward, most of the magnetic induction lines extending outward from the lower end of the micro electromagnetic iron 7141 pass through the copper coil 7152 downward. The copper coil 7152 is subjected to a rapidly changing magnetic field, and generates an induced electromotive force through electromagnetic induction phenomenon, and further generates an induced current. The induced current is received and analyzed by the second microprocessor. The second microprocessor compares the electrical signals of each copper coil 7152 received at the same time, and wirelessly sends the coordinates of the copper coil 7152 with the strongest electrical signal to the server in real time. Since one end of the micro electromagnetic iron 7141 is downward, the copper coil 7152 directly below the micro electromagnetic iron 7141 generates the largest induced current. Therefore, the index finger, the copper coil 7152 on the index finger, and the second microprocessor together form a virtual pointer on the concave arc screen 73 for operation. When the index finger moves beyond the sensing plate 715 area, the second microprocessor automatically maintains the coordinates of the copper coil 7152 closest to the area beyond the area, that is, the virtual pointer position is fixed. When the index finger moves back to the sensing plate 715 area, the virtual pointer is moved again from this point. When the moving speed of the index finger exceeds the set threshold, the system switches the index finger movement to the interface sliding on the concave arc screen 73. When it is necessary to click somewhere, the index finger knocks down the sensing plate 715, and the piezoelectric ceramic sheet 716 is subjected to extrusion and deformation to generate a polarization current, which is received by the first microprocessor and wirelessly sent to the system server. The system completes the clicking action at the corresponding position. Another way is to use the gesture control device. The position on the concave arc screen 73 in front of the user's eyes at the moment is captured by the motion capture camera 711 as the starting point. When the hand and index finger move, the system controls the concave arc screen 73 to rotate accordingly.

[0067] ④When developing the auxiliary cabin, the user can rotate the seat 72, the concave arc screen 73, and the convex arc screen 74 through the second servo motor 76, the third servo motor 78, and the fourth servo motor 8 respectively according to the user's requirements or needs through the operation panel 71 or the gesture control device. The motion capture camera 711 captures the user's head direction and eye focus range, and automatically rotates the seat 72, the concave arc screen 73, and the convex arc screen 74 according to the user's gaze direction in automatic mode.

[0068] ⑤When the user uses it, the concave arc screen 73 is used to display the development modules and editing conditions; the convex arc screen 74 is used to temporarily display the interfaces and modules that are not needed to be viewed on the concave arc screen 73.

[0069] The development auxiliary cabin can change the environment and atmosphere in the cabin according to the intention of the user, and realize efficient interaction between the user and the development platform system, on the one hand, by using the sealing and sound insulation characteristics of the cabin body. On the other hand, the concave arc screen and convex arc screen have the advantage of full rotation by using the lifting structure design and the surrounding design, which has a significant display advantage compared with the existing flat computer screen, including display effect and display content richness, which is not only beneficial to the viewing of the development module, but also can more conveniently view and organize the displayed content in combination with the rotatable characteristics of the concave arc screen, the convex arc screen and the seat. In addition, the interactive cabin can actively obtain the knowledge or intelligence required by the development platform system through the user through inquiry or intelligent extraction, and can realize automatic learning, automatic iteration and automatic evolution of the system in combination with the current artificial intelligence.

[0070] The user can flexibly select the operation panel linkage operation, voice operation or gesture control device operation according to his own preferences, and can also use multiple operations simultaneously, which can meet the operation needs, habits and preferences of all people; and combined with the motion capture camera, the system can automatically rotate the concave arc surface screen, convex arc surface screen and / or seat according to the turning direction and gaze direction of the user's head, thereby significantly improving the efficiency, and the gesture control device ingeniously uses and combines the piezoelectric ceramic characteristics, electromagnetic induction phenomenon and alternating electromagnetic iron features, so that the piezoelectric ceramic generates a polarization current by tapping the index finger, thereby realizing the electrical signal triggering, retaining the habit of mouse clicking, and simulating the mouse clicking effect; while the mouse must be slid on a plane with certain friction to realize the movement of the mouse arrow, but the application directly moves above the densely matrix arranged copper coils using alternating electromagnetic iron, and ingeniously adopts the way of comparing the induced electromotive force or current generated by each coil at the same time to determine the coil directly below the electromagnetic iron, so that the movement path and distance data of the index finger can be collected in real time through the pre-encoded coordinates of each coil, thereby completely realizing the movement operation of the mouse. Since the comparison is the induced electromotive force or current generated by each coil at the same time, the height and posture of the hand are not too demanding, and the hand can be completely in contact with the sensing plate or suspended above the sensing plate to move, even can move up and down, without causing large errors or mistakes in path and distance collection, thereby significantly improving the comfort of the user's hand and avoiding fatigue and mouse hand; and by setting that when the index finger moves beyond the sensing plate area, the second microprocessor automatically maintains the coordinates of the copper coil closest to the area beyond the area, i.e. the virtual pointer position is fixed, and when the index finger moves back to the sensing plate area, the virtual pointer is moved again from the starting point in the sensing plate area to control the concave arc surface screen and convex arc surface screen in a large area; and by setting that when the index finger moves at a speed exceeding the set threshold, the system switches the index finger movement to the interface sliding on the concave arc surface screen, and further combines the position on the concave arc surface screen in front of the user's gaze captured by the motion capture camera as the starting point, so that the system controls the concave arc surface screen to rotate with the hand and index finger, which can meet the habit of taking oneself as a fixed reference point.

[0071] The above describes the application in detail in general, but some modifications or improvements can be made on the basis of the application, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit and principles of the application are within the protection scope of the application.
