[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0030] As Figure 1 shown, the present invention provides a tower crane model device based on non - contact sensor obstacle avoidance, including:

[0031] A wireless central control host 1, a plurality of tower crane models 2 and a remote controller 3 all connected to the wireless central control host 1;

[0032] The remote controller 3 is used to send control signals to select the controlled tower crane model 2. The tower crane model 2 is used to measure inclination data and position data through sensors and perform corresponding actions according to the control instructions of the wireless central control host 1. The wireless central control host 1 is used to send control instructions, receive the inclination data and position data of the tower crane model 2, integrate them, and upload them to the upper computer.

[0033] Further, the wireless central control host 1 includes:

[0034] A control main board, a wireless receiving module, a wireless communication module, a battery compartment, and an interface unit;

[0035] The interface unit is used to upload the inclination data and position data of the model, charge the battery compartment, and control the on / off of the wireless receiving module and the wireless communication module. The control main board is used to obtain the inclination data and position data and perform parsing to generate control instructions. The wireless receiving module is used to receive the control signal of the remote controller 3, and the wireless communication module is used to send the control instructions to the tower crane model 2. The battery compartment is used to supply power to the control main board.

[0036] Specifically, as Figures 2-3 shown, on one side of the wireless central control host 1, there are several interfaces (the left square hole interface is an external transmission interface for uploading model status data, and the right round hole interface is a power supply port for battery charging), several buttons (the button near the external transmission interface is for the on / off switch of the wireless receiving module, and the button near the power supply port is for the on / off switch of the central control host power supply), and this side is set as the front. Inside, there is a control main board (placed on the bottom of the host near the front side) for obtaining the data transmitted back by the tower crane model 2 through the wireless communication module (placed behind the control main board near the left side), parsing the control signal of the remote controller 3 received by the wireless receiving module (placed at the bottom left of the host), and sending the parsed control signal to the corresponding tower crane model 2 through the wireless communication module. The battery compartment (placed on the right side of the central control main board) is used to supply power to the central control host, and the plug interface (placed behind the battery compartment) is used as an expansion interface.

[0037] Furthermore, as Figure 4 shown, the remote controller 3 includes:

[0038] A two - gear switch and a three - gear switch; where the switches of the same gear are in a group, divided into two groups. The 2 - gear group (with 4 combination methods) is the coefficient, and the three - gear group (with 9 combination methods) is the sub - number. The two gear groups can integrate 36 combination methods. Among them, for the 2 - gear switch, up is 0 and down is 1, and for the three - gear switch, up is 0, middle is 1, and down is 2. The final combination formula is number = (coefficient * 9 + sub - number)-1.

[0039] Specifically, the remote controller 3 selects a specified number through toggle switches (SwA and SwD are two - gear switches, SwB and SwC are three - gear switches, and the device number is selected through these two groups of switches) and displays the selected number on the display screen of the remote controller 3. It can also be achieved by the upper computer sending an instruction to select a specified device number through the connected external transmission interface, enabling the central control host to communicate with and control the model with the corresponding number. The controlled model then transmits the model status data back to the central control host, and the central control host communicates with the connected upper computer through the external transmission interface. Note: This connection method can be wireless or wired.

[0040] Furthermore, as Figures 5-6 shown, the tower crane model 2 includes:

[0041] Tower crane main body, inclination sensor, position sensor, non-contact sensing sensor, control box, rotating motor;

[0042] The inclination sensor is arranged at the bottom inside the control box below the tower top, on the side of the boom close to the tower crane main body. The position sensor is placed at the tail of the boom. The non-contact sensing sensor is arranged at the front end of the boom. The control box is arranged at a preset position of the tower crane main body. The rotating motor is arranged on the lower side of the control box;

[0043] The inclination sensor is used to monitor the boom inclination of the tower crane main body. The position sensor is used to determine the real-time positions of the sliding table and the hook of the tower crane main body. The non-contact sensing sensor is used to sense obstacles. The control box is used to receive the control instructions and integrate and upload the data obtained by the sensors.

[0044] Specifically, the tower crane model 2 is equipped with sensing sensors. On the basis of the existing functions of the tower crane model 2, an inclination sensor (arranged at the bottom inside the control box below the tower top, on the side of the boom close to the tower crane main body) and a position sensor (arranged at the tail of the boom) are added. The inclination of the boom of the tower crane model 2 can be monitored in real time through the inclination sensor, and the real-time positions of the sliding table and the hook can be determined through the position sensor. A non-contact sensing sensor (such sensors include lasers, ultrasounds, microwaves, cameras, etc.) is arranged at the front end of the tower crane boom. When the front end of the boom is about to collide with an obstacle during the rotation of the tower crane model, the tower crane model immediately stops working and gives an alarm prompt to achieve the effect of obstacle avoidance. An encoder is placed below the rotating motor (used to drive the boom to rotate), which can monitor the angle of the boom and the rotation speed at this time in real time. A control box is placed below the tower top. The control box is internally provided with a control board, which is used to receive the data of each sensor, receive the control signals sent by the central control host (receive the control signals through the on-board wireless module and make the tower crane perform corresponding actions according to the control signals), and data transmission back (used for the central control host to analyze the equipment status).

[0045] After analyzing the data of the remote controller 3, the central control host sends control signals to the tower crane model 2, and the tower crane model 2 performs corresponding actions according to the control signals. The tower crane model 2 will periodically send the model status data to the central control host.

[0046] Specifically, using MEMS digital sensor technology, integrating the tower crane safety management function, students can control through physical operation, analyze safety system data and give early warning responses, and comprehensively understand and simulate tower crane safety management. This model is applicable to various scenarios such as control centers, training classrooms, and construction exhibition halls. With the support of digital twins, it can improve people's safety awareness and reduce accident risks.

[0047] In the present specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference may be made to each other.

[0048] Specific examples are used herein to illustrate the principles and implementation manners of the present invention. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present invention. At the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of the present specification should not be construed as a limitation to the present invention.
