[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] Example 1

[0039] Please refer to Figure 1, which is a seat belt fastening status detection system provided by an embodiment of the present invention, including: a seat belt, a hook and loop, and a host; the number of the seat belts is several, each of the seat belts is equipped with at least two hooks and loops, and each of the seat belts is communicatively connected to the host.

[0040] The hook is used to hook objects, and the safety belt is used to detect objects on all the hooks configured thereon, thereby sending hooking status information of whether each hook detects an object to the host.

[0041] As a preferred embodiment, the safety belt includes a detection device, the number of which is the same as the number of hooks and loops configured for the safety belt, and each of the detection devices corresponds to the hook and loop; the detection device is used to detect objects in the hook and loop, thereby generating hooking status information corresponding to the hook and loop based on the detection results, and feeding it back to the host.

[0042] In this embodiment, each detection device needs to be compact enough to be easily installed on or near the corresponding shackle without interfering with the normal operation of the shackle. The detection device should include sensors, such as pressure sensors, displacement sensors, weight sensors, or photoelectric sensors, to detect the presence and status of objects. Preferably, a laser radar is used to detect objects in the shackle. The detection device should also have a wireless communication module, such as one utilizing Bluetooth, Wi-Fi, or a dedicated wireless communication protocol, to enable data transmission with the host computer.

[0043] Furthermore, the detection device can also include a stable power supply, which can be achieved through a built-in battery, and low power consumption should be considered to extend battery life. Energy harvesting technology (such as solar energy, vibration energy, thermal energy conversion, etc.) can also be considered to provide an additional energy source for the detection device.

[0044] In this embodiment, the hooking status of each hook is monitored in real time, potential safety problems are discovered in time, and the occurrence of accidents is reduced. At the same time, automated detection reduces the need for manual inspections, speeds up the operation process, and improves work efficiency. The precise sensor accurately detects the hooking status of the object, avoiding human misjudgment. In addition, the host centrally processes and displays the status of all hooks, making monitoring easier and more intuitive. In addition, the number and layout of the detection devices can be adjusted according to actual needs, suitable for different working environments and requirements.

[0045] As a preferred embodiment, each of the detection devices includes a laser radar and a first communication module; the laser radar is arranged on the corresponding hook ring, the laser radar is connected to the first communication module, and the first communication module is also connected to the host; the laser radar is used to emit a laser beam into the corresponding hook ring, and record the emission time of the emitted laser beam and the receiving time of the reflected laser beam, so as to calculate the reflection time according to the emission time and the receiving time; the reflection time is compared with the preset standard time to obtain the hooking status information of the hook ring; the first communication module is used to send the number of the detection device corresponding to the laser radar and the hooking status information of the corresponding hook ring to the host, so that the host can display, determine the safety level and make alarm judgments according to the hooking status information of the hook ring.

[0046] In this embodiment, the laser radar sensor can ensure that it can accurately measure the distance inside the hook, and the laser radar is fixed at the appropriate position of each hook so that it can accurately emit a laser beam into the inside of the hook and receive the reflected signal.

[0047] In this embodiment, the preset standard time is the standard time between the laser radar emitting the laser and receiving the reflected laser beam when there is no object inside the hook. When the reflection time obtained after the laser radar emits the laser beam is the same as the standard time, it means that the optical propagation path of the laser beam emitted by the laser radar in the hook is the same, that is, the current hook state is the same as the hook state when there is no object inside, indicating that there is no object inside the hook. When the reflection time obtained after the laser radar emits the laser beam is different from the standard time, it means that the optical propagation path of the laser beam emitted by the laser radar in the hook has changed, that is, the change in the optical propagation path only occurs when there is an object in the hook, indicating that there is an object in the current hook, that is, the hook is currently hanging with an object.

[0048] In this embodiment, each object detection device consists of a laser radar and a communication module. The laser radar is used to detect whether an object is hooked in the carabiner of the safety belt, and the communication module is responsible for transmitting the detection results to the host computer. The use of laser radar provides a non-contact detection method, reduces physical wear, and improves the accuracy and reliability of detection. It also monitors the hook status in real time, promptly detects problems and issues alarms, greatly improving the safety of suspension operations. The automated monitoring and alarm mechanism reduces the burden of manual inspection and avoids human error. In addition, the host computer can store historical data for easy backtracking and analysis, helping to optimize the operation process and improve future safety management levels. At the same time, the number of laser radars can be increased or decreased according to actual needs to meet the needs of suspension operations of different scales.

[0049] The host is used to determine the safety level of each seat belt based on the hooking status information sent by each seat belt, and mark the seat belts whose safety level is lower than the preset level, thereby sending an alarm signal to the marked seat belts, so that the seat belts that receive the alarm signal will emit an audible and visual alarm.

[0050] As a preferred solution, the host includes: a second communication module, an MCU and a display alarm module; the second communication module is connected to the first communication module in all the detection devices, and the MCU is connected to the second communication module and the display alarm module; the second communication module is used to communicate with the first communication module in all the detection devices, and receive the number and hooking status information of the corresponding detection device sent by the first communication module, thereby sending the number and hooking status information of the detection device to the MCU for processing; the MCU is used to calculate the safety level of the safety belt corresponding to the detection device according to the number and hooking status information of the detection device, and generate an alarm signal for the corresponding detection device according to a preset safety assessment correspondence table; the display alarm module is used to perform an audible and visual alarm for the safety belt corresponding to the detection device according to the generated alarm signal of the corresponding detection device.

[0051] In this embodiment, the host is mainly composed of an MCU processor, a power module, a keyboard module, a display and alarm module, a communication module, etc. The MCU processor is the logical calculation unit of the detection system. It analyzes whether the seat belt is effectively fastened based on the detection result data of each detection device, and outputs corresponding display and alarm information based on the judgment. The power module is powered by a battery and can provide working power for the MCU, keyboard module, display module, and communication module. The keyboard module can set the input of operating parameters (such as seat belts, device codes, etc.), process detection result data, etc. The display and alarm module can display detection results, alarm signals, etc. The communication module is responsible for collecting the detection results of each detection device, and can also be connected to the information system or the Internet of Things to realize remote transmission and analysis applications.

[0052] As a preferred solution, the safety level of the safety belt corresponding to the object detection device is calculated based on the number of the object detection device and the hook status information, and an alarm signal corresponding to the object detection device is generated according to a preset safety assessment corresponding table, specifically:

[0053] According to the number of the detection device, the safety belt corresponding to each hooking status information is determined; wherein, the hooking status information includes whether there is an object in each hook ring corresponding to the safety belt; when there are objects in at least two hook rings in the safety belt, the safety level of the safety belt of the detection device is set to a high level, and according to the preset safety assessment correspondence table, an alarm signal corresponding to the high level is generated; wherein, the safety level includes high level, medium level and low level, and the preset safety assessment correspondence table includes alarm signals corresponding to high level, medium level and low level respectively; when there is an object in only one hook ring in the safety belt, the safety level of the safety belt of the detection device is set to a medium level, and according to the preset safety assessment correspondence table, an alarm signal corresponding to the medium level is generated; when there is no object in each hook ring in the safety belt, the safety level of the safety belt of the detection device is set to a low level, and according to the preset safety assessment correspondence table, an alarm signal corresponding to the low level is generated.

[0054] In this embodiment, referring to Figure 2, each set of safety belts used for height-ascending work is numbered: Safety Belt 1, Safety Belt 2, ..., Safety Belt N. The detection devices attached to the hooks of the two safety ropes of each safety belt are sequentially numbered: Detection Device 1A, Detection Device 1B, Detection Device 2A, Detection Device 2B, ..., Detection Device NA, Detection Device NB. This ensures that each detection device has an independent IP number and is associated with the corresponding safety belt, ensuring that the detection device corresponds to the safety belt. The detection results of the detection device (whether there is an object hooked in the hook) can then be used to determine the safety belt fastening status. If a safety belt is found to be in an invalid state, an alarm signal is immediately issued.

[0055] In this embodiment, each level of safety corresponds to a specific application scenario. For example, a high safety level indicates that at least two carabiners in the safety belt have objects attached. Typically, a safety belt only requires two carabiners, one main carabiner and one backup carabiner. When each carabiner has an object attached, the safety belt is complete and can ensure the safety of the worker. A medium safety level indicates that only one carabiner in the safety belt has an object attached, while the other carabiner is not attached. This indicates that the worker may be in a mobile phase and may need to remove the carabiner from a fixed point to be able to move at high altitude, but requires real-time monitoring and guidance from ground personnel. A low safety level indicates that no carabiner in the safety belt has an object attached, meaning that no carabiner is attached to an object. Workers working at height may be at risk of falling, requiring a timely audible and visual alarm to prompt the worker to attach the safety hook, with feedback provided to the ground personnel's host computer.

[0056] As a preferred solution, the alarm signal generated by the corresponding object detection device is used to generate an audible and visual alarm for the seat belt corresponding to the object detection device, specifically:

[0057] When the seat belt generates a high-level or medium-level alarm signal, it shows that the seat belt is effectively fastened; when the seat belt generates a low-level alarm signal, it shows that the seat belt is invalidly fastened, and generates an audible and visual alarm signal, and sends it to the corresponding seat belt through the second communication module, so that the seat belt will synchronously perform audible and visual alarms.

[0058] As a preferred solution, the second communication module is further configured to:

[0059] The safety belts are communicated with in turn, so that after each safety belt sends hooking status information for a preset time, it establishes a communication connection with the next safety belt, thereby receiving the hooking status information sent by the next safety belt; wherein the time for each safety belt to establish communication with the second communication module is the preset time.

[0060] In this embodiment, each safety belt for height work is numbered: Safety Belt 1, Safety Belt 2, ..., Safety Belt N. The detection devices attached to the hooks of each safety belt are sequentially numbered: Detection Device 1A, Detection Device 1B, Detection Device 2A, Detection Device 2B, ..., Detection Device NA, Detection Device NB. This ensures that each detection device has an independent IP number and is associated with the corresponding safety belt, ensuring a corresponding detection device. Detection devices 1A and 1B of safety belt 1 sequentially emit laser beams to detect whether an object is hooked in their respective hooks and transmit the detection results to the MCU processor via a communication module. Based on the received detection results and the association information between the detection devices and the safety belt, the MCU processor determines whether safety belt 1 is securely fastened and displays the result on the "display alarm module." If safety belt 1 is deemed invalidly fastened, an alarm signal, such as light or sound, is emitted. If at least one of the detection results of the detection device 1A and the detection device 1B of the seat belt 1 is a valid hook, the seat belt 1 is considered to be effectively tied; if the detection results of the detection device 1A and the detection device 1B of the seat belt 1 are both invalid hooks, the seat belt 1 is considered to be invalidly tied, and an alarm signal is immediately issued. Thus, the seat belt 2, ..., and the seat belt N are detected in turn to see if they are effectively hooked. If any seat belt is found to be invalidly tied, an alarm signal is immediately issued. At preset time intervals (preferably, the preset time is 1 second), the seat belt 1, the seat belt 2, ..., and the seat belt N are cyclically detected to see if they are effectively hooked. If any seat belt is found to be invalidly tied, an alarm signal is immediately issued.

[0061] As a preferred solution, the host further includes: a keyboard module and a power module; the keyboard module is used to set the parameters of the preset safety assessment correspondence table in the MCU in response to the user's parameter input, and to customize the safety level of the seat belt; the power module is used to power the MCU, the keyboard module, the display module and the second communication module.

[0062] As a preferred solution, the second communication module is further configured to:

[0063] The safety level of each seat belt is sent to the cloud server so that the cloud server can monitor, record and store the status of each seat belt in real time.

[0064] In this embodiment, to address the current lack of detection methods to accurately determine whether all high-altitude workers are effectively fastened during high-altitude movement or multi-person high-altitude work, a laser radar detection device is used to establish a relationship between the detection device, safety belts, and the workers performing the work at height. By sequentially detecting and collecting signals indicating whether the hooks of each safety rope on the safety belts of all high-altitude workers are effectively hooked, combined with the relationship between the workers, safety belts, and the detection device, an analysis is performed to determine whether the safety belts are effectively hooked. If any safety belts are found to be ineffectively fastened, an alarm signal is immediately issued. Furthermore, through the host computer's overall monitoring of the safety belts, supervisors and managers on the ground can fully understand the safety belt fastening status of workers performing the work at height, promptly identify those whose safety belts are ineffectively fastened, and promptly remind workers to effectively fasten their safety belts, further ensuring the personal safety of workers performing the work at height and effectively preventing falls from height.

[0065] It can be understood that the system of this embodiment can establish the relationship between the detection device, the safety belt, and the climbing workers, and sort out the information collection chain of the detection device, the safety belt, and the IP code of the climbing workers. Then, by collecting the signal of whether the detection device of the two (or one) safety ropes of a certain safety belt is effectively hooked and performing a logical operation, the hanging state of the safety belt can be determined. In addition, by collecting the signal of whether the detection device of the safety rope of the safety belt of the climbing workers is effectively hooked and performing a logical operation, the hanging state of the safety belts of all the climbing workers can be determined, and according to the detection result of the safety belt hanging state, an immediate alarm is issued for the invalid hanging situation, realizing the real-time discovery of whose safety belt is invalidly hung by technical means, so that the climbing workers can be reminded and warned to effectively fasten the safety belt in time, effectively preventing high-altitude falls.

[0066] The implementation of the above embodiment has the following effects:

[0067] The technical solution of the present invention is to configure at least two hooks for each safety belt, and all safety belts are communicatively connected to the host, so as to monitor the object detection status of each hook in real time, thereby ensuring the accuracy of the detection results. At the same time, the system can distinguish whether each hook has successfully hooked the object, and can accurately identify unhooked or unsafely hanging objects, thereby improving the accuracy of the detection system. The host can automatically process information from multiple safety belts, and quickly determine the safety level and issue an alarm signal, reducing the time for manual inspection and improving overall work efficiency. By monitoring the hooking status of the safety belts in real time, the host can promptly identify situations below the preset safety level and immediately send an alarm signal to the relevant safety belts. The safety belts that receive the alarm signal will issue an audible and visual alarm to remind the operator to take necessary safety measures, thereby effectively preventing potential safety accidents. In addition, it can support centralized monitoring of multiple safety belts, which is conducive to unified management and avoids safety hazards caused by negligence of individual personnel.

It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. In particular, it should be noted that any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of protection of the present invention for those skilled in the art.
