Description

Technical Field

[0001] This application relates to the field of engineering equipment technology, specifically to a detection system for the boom of engineering machinery approaching a high-voltage line, and the engineering machinery itself. Background Technology

[0002] Construction machinery, such as concrete pump trucks, has long booms and many joints, creating blind spots for operators during operations and making it difficult to judge the safe distance between the boom and surrounding obstacles. This is especially true when working near high-voltage power lines; if the boom enters the safe distance zone of the power line, the induced electric field can be too strong, causing the air to break down and resulting in electric shock accidents, leading to personal injury and property damage.

[0003] Existing technology uses modular sensing devices installed on the boom to detect high-voltage lines. However, in order to detect high-voltage lines, the ideal installation position of the sensing device usually interferes with the boom structure. In addition, taking the location of the sensing device on the boom as the detection center point, the sensing ability of other locations on the boom gradually weakens as they are further away from the detection center point, resulting in uneven protection range of the entire boom and poor protection effect. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a detection system for the boom of construction machinery approaching high-voltage lines. The system designs the high-voltage line detection component as an antenna extending along the length of the boom segment, replacing the detection point with a detection surface, thereby improving the sensing capability of the high-voltage line and ensuring that the protection range covers the entire boom segment. Furthermore, when high-voltage line detection components are installed on multiple boom segments simultaneously, interference between the high-voltage line detection component and the boom segment structure can be reduced or avoided.

[0021] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. In this application, "each" includes one or more items.

[0023] Figure 1 This is a schematic diagram of a detection system for the boom of an engineering machine approaching a high-voltage line, according to one embodiment. Figure 2 This is a schematic diagram of the mounting structure of a high-voltage line detection assembly on a boom, according to one embodiment. Figure 1 and Figure 2 As shown, the engineering machinery in this embodiment includes a boom 80, which includes multiple boom sections 801. The detection system includes a high-voltage line detection component 20 and a controller 10. The high-voltage line detection component 20 is disposed on at least one boom section 801. The high-voltage line detection component 20 is an antenna extending along the length direction of the boom section 801. The high-voltage line detection component 20 corresponding to each boom section 801 is connected to the controller 10 respectively.

[0024] The high-voltage line detection component 20 is designed as an antenna extending along the length of the arm section 801, with the detection surface replacing the detection point, which improves the sensing capability of the high-voltage line and ensures that the protection range covers the entire arm section 801. Furthermore, when the high-voltage line detection component 20 is installed on multiple arm sections 801 at the same time, the interference between the high-voltage line detection component 20 and the arm section 801 structure can be reduced or avoided.

[0025] In some embodiments, the high-voltage line detection components 20 corresponding to each boom segment 801 are connected to the high-voltage line alarm controller 101, which is connected to the controller 10. The controller 10 and the high-voltage line alarm controller 101 communicate bidirectionally via CAN. Thus, the high-voltage line detection components 20 corresponding to each boom segment 801 are indirectly connected to the controller 10, enabling modular installation between the controller 10 and the high-voltage line detection components 20. The high-voltage line alarm controller 101 can independently process the detection data of the high-voltage line detection components 20, such as amplifying, reducing noise, and performing digital-to-analog conversion, reducing the computational load of the controller 10 and improving system robustness. In some embodiments, the functions of the high-voltage line alarm controller 101 can also be integrated into the controller 10, with the high-voltage line detection components 20 corresponding to each boom segment 801 directly connected to the controller 10, thereby simplifying the wiring structure.

[0026] Please combine Figure 2 and Figure 3 In some embodiments, the high-voltage line detection component 20 is a conductor-type cable. By deploying the high-voltage line detection component 20 as a conductor-type cable, the deployment method is simple, and there is no need to design the high-voltage line detection component 20 with a modular structure, thereby avoiding the problem of interference between the high-voltage line detection component 20 and the movement of the boom segment 801 of the boom 80 when installing the high-voltage line detection component 20.

[0027] In some embodiments, the high-voltage line detection component 20 forms a closed loop with two conductors extending along the length of the arm section 801, thereby forming a detection circuit. When any part of the high-voltage line detection component 20 breaks, the detection data is interrupted, and the high-voltage line alarm controller 101 or controller 10 can detect the abnormal state of the high-voltage line detection component 20 in a timely manner.

[0028] In some embodiments, the high-voltage line detection assembly 20 includes a shielding section 21 and a sensing section 22. The sensing section 22 extends along the length of the boom 801, and the shielding section 21 extends from one end connected to the controller 10 along the boom 80 to the sensing section 22. The sensing section 22 of the high-voltage line detection assembly 20 generates an induced current in the electromagnetic field of the high-voltage line. Therefore, by placing the sensing section 22 on the boom 801 where the user wants to protect it, and the remaining portion being the shielding section 21, the high-voltage line detection assembly 20 can be prevented from being subjected to electromagnetic interference from the vehicle chassis engine or other devices.

[0029] Please refer to Figure 2Taking a boom 80 comprising four boom sections 801 as an example, for high-voltage line proximity alarms on both the 3-section boom (the 3rd section from left to right) and the 4-section boom (the 4th section from left to right), two high-voltage line detection components 20 are required. The first high-voltage line detection component starts from the high-voltage line alarm controller 101 and extends along the boom 80 to the 3rd section. Except for the sensing section 22 on the 3rd section, the remaining parts of the first high-voltage line detection component are shielded sections 21. The second high-voltage line detection component starts from the high-voltage line alarm controller 101 and extends along the boom 80 to the 4th section. Except for the sensing section 22 on the 4th section, the remaining parts of the second high-voltage line detection component are shielded sections 21. When the third section of boom 80 approaches the high-voltage line, the sensing segment 22 on the third section of the first high-voltage line detection component is affected by the electric field, while the others are in a shielded state. The fourth section of boom is not close to the high-voltage line, and its sensing segment 22 will not generate a sensing signal or will generate a weak sensing signal. Thus, the boom section number that is close to the high-voltage line can be located based on the difference in detection data. The other boom sections are located in the same way.

[0030] Thus, through the design of shielding section 21 and sensing section 22, the electromagnetic interference of the sensing signal can be reduced. At the same time, the boom section 801 closest to the high voltage line can be located based on the difference in detection data. This allows the operator to be accurately informed of the boom section 801 closest to the high voltage line and to guide the operator to adjust the position of the boom 80.

[0031] In some embodiments, the shielding section 21 and the sensing section 22 are an integral structure, that is, the shielding section 21 and the sensing section 22 are continuous wires, and the outer surface of the shielding section 21 is covered with a shielding material layer to achieve the shielding function. This simplifies the design of the high-voltage line detection component 20 and makes the structure more reliable under the conditions of frequent and large-angle movement of the boom 80.

[0032] In some embodiments, the length of the sensing segment 22 is greater than or equal to the length of the corresponding boom segment 801. The length of the sensing segment 22 refers to the length of the sensing segment 22 in the straightened state. When the length of the sensing segment 22 is greater than or equal to the length of the corresponding boom segment 801, the sensing segment 22 can be arranged according to the surface structure of the boom segment 801 so that it fits the surface of the boom segment 801 better, reducing the impact on the operation process. At the same time, it can meet the requirements of deployment within the entire length of the boom segment 801, ensuring that the protection range covers the entire boom segment 801.

[0033] In some embodiments, please refer to Figure 1The detection system also includes an image acquisition device 60 and a video recorder 50. The image acquisition device 60 is mounted on the boom 80 and connected to the video recorder 50, which is connected to the controller 10. The controller 10 and the video recorder 50 communicate bidirectionally via CAN. The image acquisition device 60 is mounted on the boom 80; for example, one or more image acquisition devices 60 can be mounted on each boom segment 801. The image acquisition device 60 is connected to the controller 10 via the video recorder 50, which stores the images or videos acquired by the image acquisition device 60.

[0034] In some embodiments, the detection system further includes a display screen 30 connected to the controller 10. The display screen 30 provides a parameter setting interface and displays alarm data. The display screen 30 communicates bidirectionally with the controller 10 via CAN. Please refer to [reference needed]. Figure 4 Users can enable or disable the high-voltage line alarm function on the display screen 30. After enabling the alarm function, users can select the voltage level of the high-voltage line in the current working environment and the alarm distance parameter. For different voltage levels of high-voltage lines, the program presets a minimum safe distance. Based on this minimum safe distance, users can adjust the alarm distance parameter, such as far, near, or medium, to set the alarm sensitivity. Selecting a far alarm distance parameter results in the highest alarm sensitivity, and vice versa. After adjusting the alarm distance parameter, the controller 10 analyzes the detection data of the high-voltage line detection component 20 based on the alarm distance parameter to achieve accurate monitoring. The controller 10 can also send relevant alarm data to the display screen 30 for display, such as equipment status, alarm level, alarm arm section, etc., including alarm level, alarm time, and alarm video. Different alarm levels correspond to different alarm video durations.

[0035] In some embodiments, the detection system further includes an audible and visual alarm device 40 connected to the controller 10, which is used to provide on-site audible and visual alarms after receiving a high-voltage line alarm signal, so as to alert the operator to perform safe operation.

[0036] In some embodiments, the detection system further includes a receiver 70 for communicating with a remote controller and a mobile communication module for communicating with an IoT platform. The receiver 70 and the mobile communication module are respectively connected to the controller 10. The controller 10 and the receiver 70 of the remote controller communicate bidirectionally via CAN for remotely sending high-voltage alarm information and receiving control commands remotely sent by the remote controller. The remote controller and the receiver 70 are connected wirelessly via Wi-Fi. After receiving data from the image acquisition device 60, the video recorder 50 transmits the data to the IoT platform via the mobile communication module using 4G / 5G signals. Users can then simultaneously monitor the on-site alarm status through a terminal APP.

[0037] When the construction machinery is in operation, in response to a control command received to move the boom 80, the machinery controls the boom 80 to move according to the indicated posture. During the movement of the boom 80, based on the detection data from the high-voltage line detection component, it determines whether the boom 80 is approaching a high-voltage line. If it is determined that the boom 80 is close to the high-voltage line, corresponding control measures are implemented on the boom 80, such as stopping its movement or locking it. The high-voltage line detection component generates a corresponding detection signal, such as an induced current signal, when the boom approaches a high-voltage line. The magnitude of the detection data from the high-voltage line detection component determines the degree of proximity between the boom 80 and the high-voltage line. When it is determined that the boom 80 is close to the high-voltage line, it means that the boom 80 is within the danger zone of the high-voltage line.

[0038] The control command for the movement of the boom 80 can be triggered by the operator operating a handle on the remote control and transmitted wirelessly to the receiver 70 on the construction machinery, and then received by the controller 10 on the construction machinery. Alternatively, the control command can be triggered by the operator in the cab of the construction machinery by operating a handle. Based on the movement posture indicated by the control command, the controller 10 generates corresponding control signals to control the movement of the boom 80. During the movement of the boom 80, the detection data from the high-voltage line detection component 20 determines whether the boom 80 is approaching a high-voltage line, thus avoiding situations where blind spots or poor visibility during nighttime construction prevent timely detection of the boom 80 approaching a high-voltage line.

[0039] When the boom approaches a high-voltage line, the remote control interface will provide corresponding warnings based on the level of danger. For lower-level warning signals, the remote control interface displays a yellow icon and text message indicating the presence of a high-voltage line in the work area, accompanied by a short beep. For higher-level danger signals, the remote control interface displays a red icon and text message indicating that the boom has entered the danger zone of the high-voltage line, accompanied by a rapid beep.

The construction machinery includes a boom, which comprises multiple boom sections. The detection system includes a high-voltage power line detection component and a controller. The high-voltage power line detection component is mounted on at least one boom section and is an antenna extending along the length of the boom section. Each boom section's corresponding high-voltage power line detection component is connected to the controller. The technical solution of this application designs the high-voltage power line detection component as an antenna extending along the length of the boom section, using a detection surface instead of a detection point, thereby improving the sensing capability for high-voltage power lines and ensuring that the protection range covers the entire boom section.
