Description

Technical Field

[0001] The present invention relates to the technical field of aerial work safety equipment, and in particular to an interlocking control method and a product thereof applied to aerial work safety equipment. Background Art

[0002] Aerial work refers to work activities performed at a certain height above the ground, which is common in industries such as construction, electricity, and communications. Due to the complex environment of aerial work, workers face greater safety risks. Safety belts are very important safety equipment in aerial work and climbing activities. They prevent falls by connecting workers to fixed points. Safety work regulations require that when working on poles and towers, double-control safety belts should be used. Their function is to always keep at least one protective rope in a reliably connected state to protect the safety of workers.

[0003] In order to ensure the safety of workers working at heights, dual-control safety belts are usually used in the prior art. When working on a tower, the worker wears the safety belt according to the specifications, first reliably locks one of the safety ropes and then starts climbing. After reaching a certain height, the worker uses the other safety rope to reliably lock it, then bends down and reaches out to untie the locked safety rope below, and repeats this action in a cycle until the worker reaches the destination. During the operation, at least one safety rope is kept in a reliably connected state with the safety belt to protect the safety of the worker. However, judging from the steps of using the safety belt, there are still some risks in the design of the existing safety belt:

[0004] (1) Complicated operation: During climbing or operation shifting, the safety belt needs to be frequently unlocked and locked, which not only increases the physical exertion of the operator but also reduces the operation efficiency;

[0005] (2) Lack of safety detection: The two safety ropes cannot be linked together, and alternating operations rely on the standardized operation of the operators. Due to non-standard operation or the operators' failure to comply with regulations and actively remove the protection, the two safety ropes will be unlocked at the same time, increasing the risk of falling from height.

[0006] Therefore, there is still room for improvement in the design and use of existing dual-control safety belts. Summary of the invention

[0007] The present invention provides an interlocking control method and a product thereof applied to aerial work safety equipment to solve the above-mentioned problems existing in the existing dual-control safety belt.

[0008] The present invention is achieved through the following technical solutions:

[0009] In a first aspect of the present invention, an interlock control method for high-altitude operation safety equipment is provided. The high-altitude operation safety equipment includes a first safety component and a second safety component. The first safety component and the second safety component respectively use a first electronic lock and a second electronic lock to achieve binding and unbinding with a fixed object. The interlock control method includes:

[0010] In response to a first unlocking request, obtain the locking state information of the first electronic lock and the second electronic lock. If the locking states of the first electronic lock and the second electronic lock are not both released, send a first control signal to the unlocking target of the first unlocking request, so that the unlocking target releases its own locking state according to the first control signal. The unlocking target is the first electronic lock or the second electronic lock;

[0011] In response to a second unlocking request, send a second control signal to the unlocking target, so that the unlocking target performs an unlocking action. The second unlocking request is triggered within a predetermined time period after the first unlocking request;

[0012] In response to a locking request, send a third control signal to the locking target of the locking request, so that the locking target performs a locking action according to the third control signal. The locking target is the first electronic lock or the second electronic lock;

[0013] In response to a locking signal, send a fourth control signal to the first electronic lock or the second electronic lock, so that the first electronic lock or the second electronic lock performs a locking action according to the fourth control signal. The locking signal is sent by the first electronic lock or the second electronic lock in the locked state.

[0014] The present invention utilizes the programmable characteristics of the electronic lock and combines the locking mechanism on the basis of the interlock mechanism. When any unlocking signal is received, it detects whether the two electronic locks are under the protection of the locked state. Only when both electronic locks are locked, one of them is allowed to be unlocked, ensuring that the other safety component is always in the locked + locked state, preventing the operator from accidentally unlocking both at the same time, and the risk of slipping and falling caused by equipment failures (such as loose lock catches). On the basis of adding the locking protection mechanism, unlocking requires confirmation of two unlocking instructions. The first is to release the locked state, and the second is to release the locked state, avoiding direct unlocking and avoiding the risk of mis-triggering of the instructions. The locking state automatically triggers locking, that is, the electronic lock after locking remains in the locked protection state, which improves the safety level while simplifying the locking operation. The unlocking and locking processes are automatically executed by the actuator according to the instructions, without the need to bend down to manually unbind or bind, saving the energy of the operator.

[0015] In one embodiment, the method of sending a first control signal to the unlocking target of the first unlocking request is as follows: Parse the first unlocking request. If the first unlocking request is the first code, send a first control signal to the first electronic lock; if the first unlocking request is the second code, send a first control signal to the second electronic lock.

[0016] In one embodiment, the method of sending a second control signal to the unlocking target is as follows: Parse the second unlocking request. If the code of the second unlocking request is the same as the code of the first unlocking request, send a second control signal to the unlocking target; otherwise, feedback an error message.

[0017] In one embodiment, the method of sending a third control signal to the locking target is as follows: Parse the locking request. If the locking request is the third code, send a third control signal to the first electronic lock; if the locking request is the fourth code, send a third control signal to the second electronic lock.

[0018] In one embodiment, the method of sending a fourth control signal to the first electronic lock or the second electronic lock is as follows: Detect the frequency of the locking signal. If the locking signal is the first frequency signal, send a fourth control signal to the first electronic lock; if the locking signal is the second frequency signal, send a fourth control signal to the second electronic lock.

[0019] In one embodiment, the control method further includes: Obtain the position information of the first electronic lock and the second electronic lock. If the position of the first electronic lock or the second electronic lock exceeds the preset safety range, send an alarm message to the safety center.

[0020] In one embodiment, the first unlocking request and the second unlocking request are triggered by a button or a biometric module.

[0021] In a second aspect of the present invention, an interlock control system applied to high-altitude operation safety equipment is provided. The high-altitude operation safety equipment includes a first safety component, a second safety component, and a wearable component; the interlock control system includes:

[0022] A first electronic lock, installed on the first safety component, for binding or unbinding the first safety component from a fixed object;

[0023] A second electronic lock, installed on the second safety component, for binding or unbinding the second safety component from a fixed object;

[0024] A controller, installed on the wearable component, is configured to execute the interlock control method for high-altitude operation safety equipment according to any one of the first aspects of the present invention, so as to implement an interlock mechanism between the first electronic lock and the second electronic lock.

[0025] In the third aspect of the present invention, there is provided a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, it implements the interlock control method for high-altitude operation safety equipment according to any one of the first aspects of the present invention.

[0026] In the fourth aspect of the present invention, there is provided a computer program product, including instructions, which implement the interlock control method for high-altitude operation safety equipment according to any one of the first aspects of the present invention when executed by a computer.

[0027] Compared with the prior art, the present invention has the following advantages and beneficial effects: Through the interlock and locking mechanisms, combined with the locking state detection, it is ensured that during the unlocking operation of one safety component, the other safety component is always in the working state, preventing the situation that an operator accidentally unlocks two safety components simultaneously, and improving the safety protection level. When locking, the locking is automatically triggered, so that the electronic lock after locking remains in the locked state. When unlocking, the locked state needs to be released first to avoid direct unlocking, thus avoiding the risk of misoperation and further reducing the risk of slipping and falling caused by equipment failure. In addition, through the state determination, the locking and unlocking of the locked state are automatically executed. Without adding additional operations for the operator to unlock and lock the safety components in the case of the superimposed locking protection mechanism, the operator controls the alternating operation of the safety components by triggering the unlocking request and the locking request, and there is no need to bend down to manually untie or bind, saving the operation effort.

[0033] To make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the embodiments and the drawings. The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0034] It should be noted that the terms "including" and "having" in the description and claims of the present invention and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily be limited to other steps or units inherent to the process, method, system, product or device.

[0035] The terms used in the various embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the various embodiments of the present invention. As used herein, the singular form is also intended to include the plural form unless the context clearly indicates otherwise. Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the various embodiments of the present invention belong. The terms (such as those defined in a commonly used dictionary) will be interpreted as having the same meaning as the contextual meaning in the relevant technical field and will not be interpreted as having an idealized meaning or an overly formal meaning unless clearly defined in the various embodiments of the present invention.

[0036] The present invention aims to solve the following core pain points of existing safety belts in working at heights: First, during the use of existing safety belts, it is necessary to manually unlock and lock the safety belts up and down and back and forth, with frequent operations, consuming physical strength and affecting efficiency; Second, the mechanical structure is too simple and lacks an interlocking function, and it is easy to have the situation where two safety belts are unlocked at the same time, which will lead to loss of protection at high altitudes and pose a great threat to the lives and safety of operators. In order to fundamentally solve the above problems, we ingeniously incorporated an interlocking mechanism into the internal structure of the safety belt. This mechanism can ensure that in any case, the two safety belts will not be opened at the same time, thus ensuring that the operator will not lose protection at high altitudes and greatly reducing the risk of falling from a height. In addition, we also innovated the buckle operation of the safety belt. Different from the way that ordinary safety belts must directly press the hook to unlock, the hook is unlocked remotely through a wireless transmission method, saving the physical strength of the operator and also improving the operation efficiency of the operator.

[0037] The interlock control method and its product of the present invention are applied to high-altitude operation safety equipment. The high-altitude operation safety equipment includes a first safety component, a second safety component, and a wearable component. Generally, the wearable component and the safety component are connected by a buckle. The first safety component and the second safety component can be safety hooks. The safety hooks are fixedly connected to the wearable component through safety ropes. The safety hooks are unlocked by an electronic lock and automatically bound to and unbound from a fixed object through the above control. The fixed object can be a pole tower, a utility pole, a building, etc. During operation, the two safety hooks are controlled to alternately bind and unbind to achieve climbing or working displacement. The interlock control method of the present invention is applied to the alternate control of two safety components during the operation of high-altitude operation safety equipment, ensuring that at any time during operation, at least one safety component is stably bound to a fixed object, thus guaranteeing the safety of the operating personnel.

[0038] Please refer to Figure 1 , Figure 1 The figure shown is a flowchart of the interlock control method applied to high-altitude operation safety equipment, including an unlocking control step and a locking control step.

[0039] (1) Unlocking step: When receiving a first unlocking request, obtain the locking state information of the first electronic lock and the second electronic lock. If the locking states of both the first electronic lock and the second electronic lock have not been released, send a first control signal to the unlocking target of the first unlocking request, so that the unlocking target releases its own locking state according to the first control signal, where the unlocking target is the first electronic lock or the second electronic lock; when receiving a second unlocking request within a predetermined time period after the first unlocking request, send a second control signal to the unlocking target, so that the unlocking target performs an unlocking action.

[0040] In the unlocked state, two unlocking instructions need to be confirmed. The first unlocking instruction is used to release the locking state, and the second unlocking instruction is used to release the locked state, to avoid directly unlocking. If it is detected that the locking state of any electronic lock is released when the first unlocking request is triggered, the unlocking is refused to be executed. And if no second unlocking request is received within a certain time period after the first unlocking request, it can be determined that the first unlocking request is a false trigger, and the unlocking is also refused to be executed. This improves the protection level of the electronic lock and avoids the risk of false triggering of instructions. In the case where the unlocking process is automatically executed by controlling the actuator, even if one more instruction determination is added, the operation complexity of the operating personnel is still reduced.

[0041] (2) Locking step: When receiving a locking request, send a third control signal to the locking target of the locking request, so that the locking target performs a locking action according to the third control signal, where the locking target is the first electronic lock or the second electronic lock. After any electronic lock is locked and triggers a locking signal, in response to the locking signal, send a fourth control signal to the electronic lock that triggers the locking signal to control the locking target to perform a locking action.

[0042] The locking process is automatically executed by controlling the actuator, and the locking process is safer than the unlocking process and does not require multiple command confirmations. After locking, the locking information is triggered to perform automatic locking, and at the same time, the locking state can be updated according to the locking signal for the next unlocking determination. The first electronic lock or the second electronic lock triggers the locking signal at regular intervals according to its own locking state, locks immediately after performing the locking action, and locks when the locking state is released but the unlocking action is not performed for more than a certain period of time. In case of a locking failure or a locking malfunction, the next unlocking determination cannot pass, and the failure can be detected in a timely manner.

[0043] The above-mentioned unlocking and locking processes are both controlled and executed by the controller. The second unlocking request and the first unlocking request can be triggered by the same command or different unlocking commands. The second unlocking request is valid within a certain period of time after the first unlocking request is triggered, and becomes invalid after exceeding the predetermined time. At this time, it will be treated as the first unlocking request.

[0044] The first unlocking request includes an unlocking request for unlocking the first electronic lock and a request for unlocking the second electronic lock. The controller sends the first control signal to the first electronic lock or the second electronic lock according to the different requests. The locking request can also be divided into a locking request for locking the first electronic lock and a locking request for locking the second electronic lock. According to the different requests, the controller sends the second control signal to the first electronic lock or the second electronic lock. To simplify the operation, the locking request is triggered by the same command, and the controller automatically determines the double-lock object according to the states of the first electronic lock and the second electronic lock. Under the interlocking mechanism, only one unlocking is allowed at a time during high-altitude operations. Therefore, through the state of the electronic lock, it can be determined that the unlocked object is the locked object. The operator only needs to trigger the unlocking command or the locking command, and the controller automatically discriminates and executes, simplifying the operation process during climbing. The unlocking request received within a predetermined time after the first unlocking request is the second unlocking request, and the second unlocking request also includes an unlocking request for unlocking the first electronic lock and a request for unlocking the second electronic lock.

[0045] In one embodiment, both the unlocking request and the locking request can be triggered by a button or a biometric recognition module. The triggering device is installed at an easily accessible part of the wearable component, such as the shoulder strap or the waistband. The buttons are distinguished by different colors or other prominent marks corresponding to the controlled safety components. Accordingly, the same color or the same type of prominent mark is set on the corresponding safety components to establish a corresponding control relationship. When alternately using the two safety components, it can assist the operator to accurately trigger the control command. The biometric recognition module can be fingerprint recognition, gesture recognition, etc. The controller communicates with the triggering device wirelessly or wiredly, and through signal analysis, the controller can identify the electronic lock that needs to be unlocked.

[0046] The unlocking and locking steps are all executed by the controller, such as the STM32 series microcontroller chip. Through the precise control of STM32 and the coordination of multiple modules, the reliable operation of the dual security mechanism is realized at the hardware level, while taking into account high efficiency and low complexity. The microcontroller receives unlocking and locking requests through wired or wireless communication, and transmits control signals to the first electronic lock and the second electronic lock through wireless communication methods such as Bluetooth, WiFi, and Zigbee.

[0047] In one embodiment, different codes are used for the control instructions of the first electronic lock and the second electronic lock, such as the first code "0xA1" corresponds to the first electronic lock, and the second code "0xB1" corresponds to the second electronic lock. The STM32 reads the request code through the UART / SPI interface and stores it in a register for temporary storage.

[0048] For example, the method by which the controller sends the first control signal to the unlocking target (the first electronic lock or the second electronic lock) is: by parsing the received first unlocking request, if the first unlocking request is the first code A, the first control signal is sent to the first electronic lock; if the first unlocking request is the second code B, the first control signal is sent to the second electronic lock.

[0049] Furthermore, the method for the controller to send the second control signal to the unlocking target is: parsing the second unlocking request, and if the code of the second unlocking request is the same as the code of the first unlocking request, sending the second control signal to the unlocking target, otherwise feeding back error information.

[0050] In one embodiment, the method for the controller to send the third control signal to the first electronic lock or the second electronic lock is: by parsing the received locking request, if the locking request is the third code C, then sending the third control signal to the first electronic lock; if the locking request is the fourth code D, then sending the third control signal to the second electronic lock.

[0051] When the first electronic lock receives the first control signal, it releases its own locked state according to the first control signal. In the locked state, the electronic lock cannot be unlocked or locked. After the locked state is released, the unlocking operation can be performed. After unlocking, the operator can untie the first safety component from the fixed object.

[0052] By determining the locking status of the two electronic locks at the same time, the controller only unlocks one electronic lock at a time and ensures that the other electronic lock is in a safe working mode. Even if the controller receives two unlocking requests almost at the same time, or receives an unlocking request from the electronic lock of another component when the electronic lock of one component is in an unlocked or unlocked state, the two safety components will not be unlocked at the same time due to the protection and status judgment of the locking mechanism.

[0053] When the operator completes a climb or a posture adjustment, after binding the safety component to a fixed object, a locking request is triggered. The controller determines the electronic lock targeted by the locking request through parsing. After the electronic lock completes the locking, a locking signal is generated and fed back to the controller to update its own state, indicating that the locking is successful, that is, the safety component is firmly bound to the fixed object, avoiding the situation of the lock catch getting stuck or the buckle not being tightly fastened. The controller sends a state switching instruction according to the feedback locking signal, and the electronic lock performs a locking action according to the state switching instruction. After completing one locking, both electronic locks are under the locking protection mechanism, ensuring that both safety ropes work simultaneously when the operator is hanging and working, and this continues until the next unlocking step.

[0054] Please refer to Figure 2 the unlocking interaction flowchart shown. The controller and the first electronic lock and the second electronic lock implement interlocking control, including the following interaction processes:

[0055] S101. The controller receives the first unlocking request and determines the target unlocking object according to the first unlocking request;

[0056] S102. Obtain and detect the locked states of the first electronic lock and the second electronic lock. If the locked states of the first electronic lock and the second electronic lock are not released, execute S103;

[0057] S103. Send a first control signal to the target unlocking object (the first electronic lock or the second electronic lock);

[0058] S104. The first electronic lock or the second electronic lock releases its own locked state according to the first control signal;

[0059] S105. Receive the second unlocking request within a predetermined time period;

[0060] S106. Send a second control signal to the target unlocking object;

[0061] S107. The first electronic lock or the second electronic lock performs unlocking according to the second control signal.

[0062] Please refer to Figure 3 the locking interaction flowchart shown, including the following interaction processes:

[0063] S201. When receiving a locking request, determine the target locking object according to the locking request;

[0064] S202. Send a third control signal to the target locking object (the first electronic lock or the second electronic lock);

[0065] S203. The first electronic lock or the second electronic lock performs a locking action according to the third control signal;

[0066] S204. After the first electronic lock or the second electronic lock is locked, it feeds back its own status to the controller.

[0067] S205. When the controller receives the locking feedback signal, it determines the signal source and sends a fourth control signal to the source device (the first electronic lock or the second electronic lock).

[0068] S206. The first electronic lock or the second electronic lock performs a locking action according to the fourth control signal.

[0069] In one implementation, the method for the controller to send a fourth control signal to the first electronic lock or the second electronic lock is: detect the frequency of the locking signal. If the locking signal is a first frequency signal, send a fourth control signal to the first electronic lock; if the locking signal is a second frequency signal, send a fourth control signal to the second electronic lock.

[0070] The first electronic lock and the second electronic lock communicate with the controller at different frequencies to avoid signal interference. The first electronic lock or the second electronic lock is provided with a status monitoring sensor to monitor the locking status. For example, the contact closing situation is detected through a Hall sensor, a photoelectric sensor, a pressure sensor, etc. When locked, the sensor is triggered to feed back its own status to the controller, so that the controller can obtain the status of the first electronic lock and the second electronic lock. The first electronic lock always feeds back the locking signal at the first frequency, and the second electronic lock always feeds back the locking signal at the second frequency. Thus, the controller can easily identify, receive, and separately store the locking information of the first electronic lock and the second electronic lock, update the status according to the reception time, and when receiving an unlocking request, the latest status can be retrieved from the memory. Through the distinction of frequency signals, the system can accurately control the state switching of each electronic lock to ensure the effectiveness of the interlock mechanism.

[0071] In some implementations, the locking signal can be equivalent to the locked state. When the controller receives the locking signal, it sends a fourth control signal to the electronic lock that feeds back the information, that is, after locking, the locking is automatically performed. This can reduce the interaction times between the controller and the first electronic lock and the second electronic lock, thereby reducing the data processing volume and improving the response efficiency.

[0072] In some implementations, the logic for the first electronic lock and the second electronic lock to feed back the locked state to the controller is added, that is, when the first electronic lock and the second electronic lock complete the locking action, they feed back a locking signal to the controller. The controller updates the locked states of the first controller and the second controller in the memory based on the received locking signal.

[0073] In one implementation, the controller also obtains the position information of the first electronic lock and the second electronic lock, analyzes whether the position of the first electronic lock or the second electronic lock exceeds the preset safety range according to the position information, and if it exceeds, sends an alarm message to the security center.

[0074] The position information can be obtained through a GPS positioning, UWB positioning or Bluetooth positioning module, and the preset safety range can be set according to the specific conditions of the working environment. The controller can sense the distances between itself and the first electronic lock and the second electronic lock, as well as the distance between the first electronic lock and the second electronic lock in real time according to the positioning information. If the distance exceeds the general working range, there may be dangerous situations such as falling, unhooking, and falling, which can be used as a basis for judging whether the operator is operating in a standard manner. When an abnormality is detected, an alarm is sent to the background for further judgment or intervention measures to ensure the safety of the operator.

[0075] An embodiment of the present invention further provides an interlock control system applied to high-altitude operation safety equipment. As shown in FIG. 4, the interlock control system includes a first electronic lock, a second electronic lock, and a controller. The first electronic lock is installed on the first safety component and is used to bind or unbind the first safety component to or from a fixed object; the second electronic lock is installed on the second safety component and is used to bind or unbind the second safety component to or from a fixed object; the controller is installed on the wearable component and is used to execute the interlock control method for the first electronic lock and the second electronic lock. The interlock control method specifically includes:

[0076] (1) Unlock step:

[0077] In response to a first unlock request, obtain the locking state information of the first electronic lock and the second electronic lock. If the locking states of the first electronic lock and the second electronic lock are not both released, send a first control signal to the unlock target of the first unlock request so that the unlock target releases its own locking state according to the first control signal, where the unlock target is the first electronic lock or the second electronic lock;

[0078] In response to a second unlock request, send a second control signal to the unlock target so that the unlock target performs an unlock action. The second unlock request is triggered within a predetermined time period after the first unlock request.

[0079] (2) Lock step:

[0080] In response to a lock request, send a third control signal to the lock target of the lock request so that the lock target performs a lock action according to the third control signal, where the lock target is the first electronic lock or the second electronic lock;

[0081] In response to a lock signal, send a fourth control signal to the first electronic lock or the second electronic lock so that the first electronic lock or the second electronic lock performs a locking action according to the fourth control signal. The lock signal is sent by the first electronic lock or the second electronic lock in the locked state.

[0082] In one embodiment, STM32 is used as the controller. According to the parsed request code, STM32 generates a first control signal through the timer PWM module, which is amplified by the drive circuit and then sent to the electromagnetic actuator of the target electronic lock.

[0083] In one embodiment, the control system further includes a power module. The power module includes a battery and a power management unit, which is used to provide power for the entire system. The power module adopts a main and backup power supply scheme. When the main power supply is insufficient, the backup power supply is automatically switched. When not working, the power supply of the controller is switched, and the first electronic lock and the second electronic lock are disconnected from the controller, and thus are not controlled by the interlock mechanism.

[0084] In one embodiment, the first electronic lock and the second electronic lock include sensors and electronic actuators. The electronic actuator receives the controller's instructions to perform actions such as unlocking and locking. The sensor is used to detect the state of the actuators of the first electronic lock and the second electronic lock to feedback its own status information to the controller.

[0085] In one embodiment, the first electronic lock feeds back a locking signal to the controller at a first frequency, and the second electronic lock feeds back a locking signal to the controller at a second frequency.

[0086] In one embodiment, the first safety component includes a first safety hook, the second safety component includes a second safety hook, and the first electronic lock and the second electronic lock act on the tripping device of the safety hook.

[0087] In one embodiment, the interlock control system further includes a triggering device, which communicates with the controller. The triggering device uses a button or a biometric module to trigger an unlocking request or a locking request.

[0088] An embodiment of the present invention further provides a high-altitude operation safety device, which includes a first safety component, a second safety component, and a wearable component. The first safety component includes a first electronic lock, the second safety component includes a second electronic lock, and the wearable component includes a controller. The first electronic lock, the second electronic lock, and the controller are communicatively connected. The controller implements an interlock mechanism between the first electronic lock and the second electronic lock in response to an unlocking request or a locking request triggered by an operator, referring to the foregoing embodiments.

[0089] Further, display devices are provided on the first safety component and the second safety component, which are used to prompt the current working status of the first electronic lock and the second electronic lock.

[0090] In summary, by redesigning the internal structure and appearance of the safety belt and introducing automated design, the present invention has successfully solved the problem of two safety belts losing protection simultaneously during high-altitude operations and features manual remote unlocking. It not only improves the safety performance of the safety belt but also enhances the efficiency of high-altitude operations, providing a more solid guarantee for the safety of operators' lives.

[0091] An embodiment of the present invention further provides an electronic device, which includes a processor and a memory. The number of processors can be one or more. The memory, as a computer-readable storage medium, can be used to store software programs, computer-executable programs, and modules. The processor executes various functional applications and data processing of the electronic device by running the software programs, instructions, and modules stored in the memory, so as to implement the interlock control method for high-altitude operation safety equipment according to any one of the above embodiments of the present invention.

[0092] The memory mainly includes a program storage area and a data storage area.
