The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] It should be noted that, in order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Depend on Figure 1-2 The bridge hanging basket control device shown includes a control module for controlling the first template 7 and the second template 8 to move synchronously to the target position; a plurality of obstacle sensors 1 are provided for detecting obstacles within the moving range of the first template 7 and the second template 8, and the obstacle sensor 1 is electrically connected to the control module, and is used to send a feedback signal when the obstacle sensor 1 detects an obstacle, and the control module stops the movement of the first template 7 and the second template 8; a plurality of stress sensors 2 are provided for detecting the pressure of the counterweight, and the stress sensor 2 is electrically connected to the control module. The control module is a PLC controller, i.e., a programmable logic controller (PLC), a digital operation controller with a microprocessor for automatic control, which can load control instructions into the memory at any time for storage and execution. The programmable controller is composed of functional units such as a CPU, instruction and data memory, input / output interface, power supply, digital analog conversion, etc. Its control logic and control program are all prior art and will not be repeated here.

[0024] The hanging basket of the utility model includes a first template 7 and a second template 8, which are combined to form a mold frame of a bridge plate 11 for casting an extended bridge plate. The control module is connected to a terminal, which is a PC, a mobile phone or a PAD. It is preferred to use a mobile phone or a PAD terminal for ease of carrying and use. The first template 7 is detachably connected to the bridge plate 11 through a driving mechanism 10, and the second template 8 is also detachably connected to the inner cavity hole of the bridge plate 11 through the driving mechanism 10. The driving mechanism 10 is driven by a servo motor, and the servo motor is controlled by the control module, so as to adjust the extension length of the first template 7 and the second template 8.

[0025] As a further optimization scheme, the stress sensor 2 is also arranged on the side of the wedge block, so as to adjust the screwing of the screw rod 9 through the indication of the stress sensor 2 .

[0026] A further optimization scheme also includes a plurality of first distance sensors 3, which are used to detect the moving distance of the driving mechanism 10. The first distance sensor 3 is electrically connected to the control module and is used to adjust the driving force of each driving mechanism 10 when the driving moving distances of all driving mechanisms 10 are not synchronized.

[0027] A further optimization scheme also includes a plurality of second distance sensors 4, which are used to detect the distance between the first template 7 and the outer side of the bridge plate 11. The second distance sensor 4 is electrically connected to the control module and is used to detect that the distance of the advancement movement of the first template 7 does not exceed the overlapping range of the first template 7.

[0028] The further optimized solution also includes a plurality of third distance sensors 5, which are used to detect the distance between the second template 8 and the inner side of the bridge plate 11. The third distance sensors 5 are electrically connected to the control module and are used to detect that the distance the second template 8 moves does not exceed the overlapping range of the second template 8.

[0029] Furthermore, a plurality of second distance sensors 4 and third distance sensors 5 are provided and are equidistantly arranged on the sides of the first template 7 and the second template 8. By controlling the sudden change of distance sensed by the second distance sensor 4 and the third distance sensor 5, the length of the first template 7 and the second template 8 extending out of the bridge plate 11 is determined, and calibration and verification are performed with the first distance sensor 3 to ensure that the first template 7 and the second template 8 are pushed into place.

[0030] The further optimized solution also includes a plurality of cameras 6, which are respectively arranged on the top surface of the crossbeam 12, the end surface of the first template 7, and the end surface of the second template 8. The camera 6 is a visual sensor, which extracts the obstacle area by collecting the image of the current scene and using image processing and recognition technology. It can not only obtain the distance information of the obstacle, but also obtain the outline, color, size and other information of the obstacle. It is used to extract obstacles around the device and avoid accidents through information communication with the control module.

[0031] According to a further optimization scheme, the obstacle sensor 1 is an infrared sensor, an ultrasonic sensor or a lidar sensor.

[0032] The working process of this embodiment is as follows:

[0033] When the first template 7 and the second template 8 need to be moved, the terminal adjusts the control module, outputs a signal, controls the driving mechanism 10 to push the first template 7 and the second template 8 to move respectively, and the first distance sensor 3 arranged at one end of the driving mechanism 10 monitors the moving distance of the driving motor and feeds the signal back to the control module. The control module determines the targeted driving force or driving speed compensation for the motor of the driving mechanism 10 according to the distance difference of the signals of all the first distance sensors 3, so as to ensure the normal operation of the pushing out of the first template 7. At the same time, a number of second distance sensors 4 arranged on the side of the first template 7 can be arranged at equal intervals and transmit the distance signal to the control module respectively. The length of the first template 7 pushed out is determined by the sudden change of the indication of the signal of each second distance sensor 4, and compared with the signal of the first distance sensor 3, so as to improve the safety of the operation of the device.

[0034] When the second template 8 needs to be pushed out, because the second template 8 also needs to be driven and moved by the driving mechanism 10, its movement rule is similar to that of the first template 7, and will not be repeated here.

[0035] Because the first template 7 is limited and fixed by the clamping assemblies at both ends of the crossbeam 12, the clamping angle of the clamping assembly is adjusted by the screw and the wedge block in the middle of the clamping assembly. In order to ensure the clamping force of the clamping assembly, the stress sensor 2 of the utility model is set on the inclined surface of the wedge block and collects the clamping force of the clamping assembly and the wedge block to detect the clamping force of the clamping assembly and the adjusting force of the screw on the wedge block, so as to ensure the safety of the operation.

[0036] The cameras 6 respectively arranged on the top surface of the beam, the end surface of the first template, and the end surface of the second template can detect the obstacles facing them, and through AI intelligent analysis, determine whether they interfere with the movement of the first template 7 and the second template 8, thereby improving the safety of operations in a narrow environment.

[0037] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
