[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Working at heights is a high-risk job that involves the safety of workers. In order to improve the safety of workers working at heights, the present invention discloses a safety protection system for workers working at heights. Figure 1 As shown, it includes: a safety belt body, a hook, an intelligent control system, and a background management system; the hook is connected to the safety belt body, and the intelligent control system is connected to the background management system. The safety belt body is the basic part of the system, which is directly related to the life safety of the operators. The safety belt body is made of high-strength materials, has good wear resistance and tensile resistance, and can effectively protect the operators from injury during high-altitude operations. The hook is a component that connects the safety belt body and the operating equipment. The design of the hook requires firmness and reliability, and can remain stable under various working conditions. The connection method between the hook and the safety belt body is simple and easy to operate, which is convenient for operators to quickly wear and unload.

[0048] The intelligent control system is the core part of the protection system, which includes an opening and closing recognition module, an empty hanging detection module, a fall detection module, and a comprehensive detection module; these modules use sensors and data analysis to monitor the use status of the hook in real time to ensure the safety of the operators.

[0049] The opening and closing identification module is used to obtain the switch status of the hook and determine whether the hook is locked based on the switch status; this function prevents forgetting to operate before the hook operation begins and misoperation during the operation, ensuring the safety of the operator.

[0050] The empty-hanging detection module is used to obtain the pressure value of the hook and determine whether the hook is effectively hung based on the pressure value; this module can prevent the hook from operating in an empty-hanging state and avoid accidents caused by the hook falling off.

[0051] The fall detection module is used to determine whether the person wearing the safety belt has fallen; once a fall signal is detected, the system will immediately sound an alarm to remind the operating personnel and back-end management personnel to take emergency measures.

[0052] The comprehensive detection module is used to comprehensively judge whether the hook is used normally based on the switch status and hanging status; if an abnormal situation is detected, the system will issue an alarm to alert the operating personnel and back-end management personnel.

[0053] The backend management system is used to manage according to the test results of the opening and closing identification module, the empty hanging detection module, the falling detection module, and the comprehensive detection module. The backend management system can monitor and manage the high-altitude operation process in real time based on the test data. Once a problem is found, the backend management system can take immediate measures to ensure the safety of the operators.

[0054] like Figure 2 As shown, the intelligent control system further includes a wearing sensing module for detecting whether the seat belt is worn. The main function of this module is to detect whether the seat belt is worn. By detecting whether the seat belt is worn, the activation of various alarm functions can be further controlled to prevent the seat belt from triggering an alarm when it is not worn.

[0055] Furthermore, the intelligent control system also includes an alarm module for giving an alarm according to the detection results of the fall detection module and the comprehensive detection module.

[0056] Specifically, the comprehensive detection module is configured as follows:

[0057] Obtain the detection results of the wearable sensing module;

[0058] If the detection result is not worn, the alarm action will not be executed; this is because the purpose of the alarm action is to remind the user to pay attention to the usage status of the device. If the user is not wearing the device, then executing the alarm action has no practical significance.

[0059] If the detection result is wearable, in order to ensure that the device is in normal working condition, the switch status is obtained;

[0060] If the switch is in the on state, the hook is used abnormally and an alarm action is executed; this is because if the hook of a device in the on state is used abnormally, the device may not work properly and may even pose a safety hazard to the user.

[0061] If the switch state is off, obtain the suspension detection result of the empty hanging detection module. If the suspension detection result is invalid suspension, the hook is used abnormally and an alarm action is executed; if the suspension detection result is valid suspension, the hook is used normally and no alarm action is executed.

[0062] Specifically, the comprehensive detection module is also configured as follows:

[0063] If the switch state is detected as closed and the suspension detection result is valid suspension, the empty suspension detection module detects invalid suspension again and does not perform the alarm action. If the suspension state is detected as valid suspension, it will continue to perform subsequent tests to ensure the normal operation of the system. However, due to the operator's actions, the pressure detection device on the hook may not detect pressure. If the invalid suspension is detected later and the alarm continues, it may cause a false alarm.

[0064] In another embodiment, if Figure 3 As shown, the fall detection module specifically includes:

[0065] A tension detection unit, used to obtain the tension value of the hook in real time;

[0066] An acceleration detection unit, used to obtain the acceleration of the seat belt body in real time;

[0067] The judgment unit judges whether a fall occurs according to the pulling force value and the acceleration.

[0068] Specifically, the judging unit is configured to:

[0069] Determine whether the acceleration exceeds the preset acceleration. If so, calculate the tension difference based on the tension values ​​obtained in two adjacent time periods. If the tension difference is greater than or equal to the preset tension difference, it is determined that a fall event has occurred; if the tension difference is less than the preset difference, it is determined to be a normal event; if not, continue to obtain the acceleration of the seat belt body.

[0070] Fall detection module This detection method has the following advantages:

[0071] 1. Real-time: Through real-time monitoring of tension and acceleration, the risk of falling can be discovered in time, providing safety protection for operators.

[0072] 2. Accuracy: By judging the difference between acceleration and tension, it is possible to accurately determine whether a fall event has occurred, avoiding false alarms and missed alarms.

[0073] 3. Reliability: Use advanced detection technology and judgment algorithms to ensure the stable operation of the fall detection module under various working conditions.

[0074] 4. Adaptability: It can be customized according to different working environments and operating requirements to meet the needs of various types of operators.

[0075] 5. Easy to integrate: The fall detection module can be easily combined with other safety protection equipment to form a complete safety protection system.

[0076] In another embodiment, if Figure 4 As shown, the background management system includes a storage module, an analysis module and a remote alarm module;

[0077] The storage module is used to store the test results sent by the intelligent control system; the storage module is one of the key parts of the background management system. It is mainly responsible for receiving and storing the test results sent by the intelligent control system. These test results may include various data and information, such as equipment status, operating parameters, etc. The storage module needs to properly store these data for subsequent analysis and processing.

[0078] The analysis module is used to obtain and analyze the execution and processing actions of the alarm module. When the alarm module executes the alarm action for more than the preset time period and does not feedback the processing action, the remote alarm module is controlled to execute the alarm action. The analysis module is the core part of the background management system. It undertakes the task of in-depth analysis of the execution and processing actions of the alarm module. When the alarm module executes the alarm action, the analysis module will monitor it in real time. Once it is found that the alarm action exceeds the preset time period, but the alarm module fails to feedback the processing action in time, the analysis module will immediately take measures to control the remote alarm module to execute the alarm action.

[0079] The remote alarm module is used to perform alarm actions according to the analysis module. The remote alarm module is the key part of the background management system responsible for implementing alarm actions. It alarms potential hidden dangers according to the instructions of the analysis module. The alarm actions of the remote alarm module can include sending alarm information, issuing alarms, etc., to remind relevant personnel to deal with potential risks in a timely manner.

[0080] Specifically, the protection system of the present invention includes at least two hooks.

[0081] On the other hand, an embodiment of the present invention further provides a method for protecting workers at heights, which is applied to the above-mentioned system for protecting workers at heights, and includes:

[0082] Get the hook switch status of the seat belt to determine whether the hook is locked;

[0083] Obtain the pressure value of the hook, and determine the hanging state of the hook according to the pressure value;

[0084] Obtain the acceleration of the seat belt body and the tension of the hook to determine whether the person wearing the seat belt has fallen;

[0085] Alarm according to the switch status, hanging status and whether the hook has fallen;

[0086] Obtain the alarm execution action and processing action of the alarm module, and control the execution of remote alarm according to the alarm action and processing action.

[0087] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments.
