Description

[0002] Because some construction workers with weak safety awareness have a mentality of taking chances and do not use safety ropes in a standardized manner, even if additional safety inspectors are added, it is difficult to conduct real-time inspections one by one to ensure safe construction. In addition, during the construction process, construction workers use the safety ropes incorrectly, resulting in the safety ropes failing to protect the construction workers during use.

Workers who do not use the safety rope properly cannot be restrained in time, resulting in safety hazards during the construction process. Summary of the Invention

[0023] Please refer to Figure 1 The present invention provides a safety rope control system, comprising: a box body 7, a rope body 2 is arranged in the inner cavity of the box body 7, a connecting buckle 8 is arranged at the first end of the rope body 2, a connecting hook 1 is arranged at the second end of the rope body 2, a lock body 3 is arranged on the box body 7, and the lock body 3 has an open state in which the box body 7 is opened and a closed state in which the box body 7 is closed; a first detection component and a safety helmet, the first detection component is arranged on the safety helmet, and the first detection component is used to detect the working state of the operator wearing the safety helmet; a second detection component and a safety belt, the second detection component is arranged on the safety belt, and the second detection component is used to detect the working state of the operator wearing the safety belt; a third detection component, the third detection component is arranged on the rope body 2, and the third detection component is used to detect the use state of the rope body 2; the connecting hook 1 is used to be connected to the external fixing component, and the connecting buckle 8 is used to be connected to the safety belt, the first detection component, the second detection component and the third detection component are all communicatively connected to the lock body 3, so that when the first detection component and the second detection component both detect that the operator is in a normal working state, and when the third detection component detects that the rope body 2 is in a safe use state, the lock body 3 is controlled to switch to the open state.

[0024] The safety rope control system of the present invention includes a box 7, a first detection component, a safety helmet, a second detection component, a safety belt and a third detection component. A rope body 2 is provided in the inner cavity of the box 7, a connecting buckle 8 is provided at the first end of the rope body 2, and a connecting hook 1 is provided at the second end of the rope body 2. A lock body 3 is provided on the box 7, and the lock body 3 has an open state for opening the box 7 and a closed state for closing the box 7. The working state of the operator wearing the safety helmet is detected by the first detection component, the working state of the operator wearing the safety belt is detected by the second detection component, and the use state of the rope body 2 is detected by the third detection component. Only when the first detection component and the second detection component both detect that the operator is in a normal working state and the third detection component detects that the rope body 2 is in a safe use state, the lock body 3 will switch to the open state, so that the rope body 2 can be taken out of the box 7, so that the operator can use the rope body 2, thereby preventing the operator from using the safety rope improperly, thereby solving the problem that the safety rope detection device in the prior art cannot stop the behavior of improper use of the safety rope in time before the construction work starts.

[0025] Specifically, when the operator does not use the safety rope properly, the third detection component will detect that the rope body 2 is in a dangerous use state. At this time, the lock body 3 is in a closed state, and the rope body 2 cannot be taken out of the box 7 for use.

[0026] In this embodiment, the third detection component includes a third detection component, a fourth detection component and a fifth detection component. The third detection component is arranged between the rope body 2 and the connecting hook 1 to detect the real-time tension applied to the rope body 2; the fourth detection component is used to detect the real-time difference between the height of the highest point of the safety belt and the height of the lowest point of the connecting hook 1; the fifth detection component is used to detect whether the connecting hook 1 is in a connected state, so that when the real-time tension is less than the maximum tension, and when the real-time difference is less than 0, and when the connecting hook 1 is in a connected state, the third detection component detects that the rope body 2 is in a safe use state.

[0027] Specifically, only when the real-time tension is less than the maximum tension, and the real-time difference is less than 0, and the connecting hook 1 is in a connected state, the third detection component will detect that the rope body 2 is in a safe use state, so that the lock body 3 can be switched to the open state, thereby avoiding the real-time tension exceeding the maximum tension and causing the rope body 2 to break. At the same time, it can avoid the height of the highest point of the safety belt being greater than or equal to the height of the lowest point of the connecting hook 1, resulting in the phenomenon of low hanging and high use. At the same time, it can avoid the connecting hook 1 being in a disconnected state, that is, the connecting hook 1 is not fully closed, resulting in a loose connection between the connecting hook 1 and the external fixing component; by setting the third detection component, the fourth detection component and the fifth detection component, it can avoid the operator from using the safety rope improperly.

[0028] In specific implementation, the third detection component is a resistive strain sensor. Since the tension range corresponding to different rope bodies 2 is also different, a safety threshold is set according to the tension range of the rope body 2. When the real-time tension value detected by the resistive strain sensor is greater than the safety threshold, an alarm is issued in time. This sensor is set to avoid exceeding the maximum tension range of the rope body 2.

[0029] In specific implementation, the fourth detection part is a tilt sensor. The tilt sensor is a sensor that can measure the tilt angle or posture of an object relative to the direction of gravity. It has high measurement accuracy and can meet the angle measurement requirements of various application scenarios. When the height of the highest point of the safety belt is greater than or equal to the lowest point of the connecting hook 1, an alarm will be issued in time. The sensor is set to avoid the situation where the operator hangs low and uses it high during operation.

[0030] In this embodiment, a fifth detection member is provided at one end of the rope body 2 close to the connecting hook 1, and the fifth detection member is a Hall sensor. A first magnetic member 9 is provided at the end of the connecting hook 1; wherein, when the first magnetic member 9 is close to the fifth detection member, the output end of the Hall sensor is at a low level, and the fifth detection member detects that the connecting hook 1 is in a connected state; when the first magnetic member 9 is away from the fifth detection member, the output end of the Hall sensor is at a high level, and the fifth detection member detects that the connecting hook 1 is in a disconnected state.

[0031] Specifically, by observing whether the output end of the Hall sensor is at a low level or a high level, it can be determined whether the first magnetic part 9 is close to or away from the fifth detection part, and then whether the connecting hook 1 is fully closed can be determined, that is, it can be determined whether the connecting hook 1 is in a connected state or a disconnected state, thereby ensuring the reliability of the fifth detection part in detecting whether the connecting hook 1 is in a connected state.

[0032] In this embodiment, the connecting hook 1 and the connecting buckle 8 are both located on the outside of the box body 7, and a first through-hole and a second through-hole are respectively provided on the two circumferential side walls of the box body 7. The first through-hole and the second through-hole are respectively used to pass through the first end and the second end of the rope body 2, so that the second end and the first end of the rope body 2 are connected to the connecting hook 1 and the connecting buckle 8 respectively; a buffer sleeve 5 is also provided in the inner cavity of the box body 7, and the buffer sleeve 5 is used to reduce the impact force on the operator. The buffer sleeve 5 is sleeved on the rope body 2, and the buffer sleeve 5 is arranged close to the connecting buckle 8; wherein, the cross-sectional area of ​​the buffer sleeve 5 in the direction perpendicular to the axial direction of the rope body 2 is larger than the flow cross-sectional area of ​​the first through-hole.

[0033] Specifically, when a fall occurs, the cushioning sleeve 5 can sacrifice part of the impact energy through its own structure and material properties, thereby reducing the impact force on the operator, thereby providing additional safety protection for the operator.

[0034] Specifically, the cross-sectional area of ​​the buffer sleeve 5 in a direction perpendicular to the axial direction of the rope body 2 is larger than the flow cross-sectional area of ​​the first through-hole, which can prevent the rope body 2 from being pulled out directly from the first through-hole, resulting in the rope body 2 still being usable when the lock body is in the closed state.

[0035] In this embodiment, an alarm component 10 is also provided on the box body 7. The first detection component, the second detection component and the third detection component are all communicated with the alarm component 10, so that when the first detection component or the second detection component detects that the operator is in an abnormal working state, or when the third detection component detects that the rope body 2 is in a dangerous use state, the alarm component 10 is controlled to sound an alarm and control the lock body 3 to switch to a closed state.

[0036] Specifically, when the first detection component or the second detection component detects that the operator is in an abnormal working state, or when the third detection component detects that the rope body 2 is in a dangerous use state, an alarm is sounded through the alarm component 10 to promptly remind the operator.

[0037] Optionally, the alarm element 10 is an alarm buzzer.

[0038] Specifically, a handle 4 is provided on the box body 7 to facilitate operators to move the box body 7 ; an adjuster 6 is also provided in the box body 7 , and the adjuster 6 is used to adjust the length of the rope body 2 .

[0039] In this embodiment, the first detection component includes a temperature detection component, a heart rate detection component and a blood pressure detection component. The temperature detection component is used to detect the real-time temperature of the working environment of the operator wearing a safety helmet, the heart rate detection component is used to detect the real-time heart rate of the operator wearing a safety helmet, and the blood pressure detection component is used to detect the real-time blood pressure of the operator wearing a safety helmet, so that when the real-time temperature is within a preset temperature range, the real-time heart rate is within a preset heart rate range, and the real-time blood pressure is within a preset blood pressure range, the first detection component detects that the operator is in a normal working state.

[0040] Specifically, only when the real-time temperature is within the preset temperature range, the real-time heart rate is within the preset heart rate range, and the real-time blood pressure is within the preset blood pressure range, will the first detection component detect that the operator is in a normal working state, so that the lock body 3 can be switched to the open state, thereby preventing the operator from working in a high or low temperature environment, and preventing the operator's real-time blood pressure and real-time heart rate from being too high or too low, thereby ensuring the operator's health; by setting up temperature detection components, heart rate detection components and blood pressure detection components, the probability of operators making operational errors and causing danger during high-altitude operations can be avoided.

[0041] In specific implementation, when the maximum temperature of the day reaches above 40℃, outdoor high-altitude work should be stopped on that day; when the maximum temperature of the day reaches above 37℃ and below 40℃, the cumulative outdoor work time of the workers shall not exceed 6 hours, and the continuous work time shall not exceed the national regulations. When the temperature is below -20℃, it may affect the performance of the equipment, material strength, etc., increase the risk of the operation, and the outdoor high-altitude work should be stopped on that day; the heart rate detection component and the blood pressure detection component are engraved as photoelectric sensors (PPG); the temperature detection component can be an infrared temperature sensor, a thermocouple sensor or an integrated temperature sensor, preferably an infrared temperature sensor.

[0042] In this embodiment, the second detection component includes a safety buckle detection component, a wind speed detection component, an acceleration detection component and a sixth detection component. The safety buckle detection component is used to detect whether the safety buckle on the safety belt is in a fastened state; the wind speed detection component is used to detect the real-time wind speed of the working environment of the operator wearing the safety belt; the acceleration detection component is used to detect the real-time acceleration of the operator wearing the safety belt; the sixth detection component is used to detect whether the safety belt is in a complete state; when the safety buckle is in a fastened state, the real-time wind speed is in a preset wind speed range, the real-time acceleration is in a preset acceleration range, and the sixth detection component detects that the safety belt is in a complete state, the second detection component detects that the operator is in a normal working state.

[0043] Specifically, only when the safety buckle is in the engaged state, the real-time wind speed is in the preset wind speed range, the real-time acceleration is in the preset acceleration range, and the sixth detection component detects that the safety belt is in a complete state, the second detection component will detect that the operator is in a normal working state, avoiding the risk of the safety belt falling off due to the safety buckle of the safety belt being in a detached state, avoiding the real-time wind speed being high, resulting in an increased risk of high-altitude operations for the operator, avoiding the acceleration of the equipment the operator rides being too large or too small to rise or fall, which does not meet the high-altitude operation specifications, and avoiding the use of the seat belt when it is damaged, resulting in an increased risk of high-altitude operations; by setting the safety buckle detection component, the wind speed detection component, the acceleration detection component and the sixth detection component, it can be avoided that the safety belt malfunctions and the probability of the operator making operational errors and causing danger during high-altitude operations is increased.

[0044] Specifically, the wind speed detector is a hot-wire anemometer. A thin wire or film heated by an electric current is exposed to the airflow. The flow of air removes heat from the hot wire, causing its temperature to drop and its resistance to change. By measuring the change in the hot-wire's resistance, the airflow velocity can be inferred, and the safety status of high-altitude operations can be determined based on the real-time wind speed. When gusts reach level 5 or above (wind speeds above 8.0m / s), operations should generally be suspended. For special high-altitude operations, such as those in strong winds, operations are prohibited when encountering gusts of level 6 or above (wind speeds above 10.8m / s).

[0045] Specifically, the acceleration detection component is a MEMS acceleration sensor, which is manufactured based on micro-electromechanical system (MEMS) technology. It is small in size, light in weight, and low in cost. It detects the acceleration of workers rising or falling during high-altitude operations. Since workers control the equipment to move up and down during high-altitude operations, the speed of the equipment also affects the safety of the equipment. A real-time acceleration safety threshold is set, and an alarm is triggered when the acceleration sensor value exceeds the safety threshold.

[0046] In this embodiment, a conductive wire is provided at the edge of the seat belt body, and the conductive wire is connected to the sixth detection component. When the conductive wire is damaged, the voltage sensed by the sixth detection component is equal to 0; when the conductive wire is intact, the voltage sensed by the sixth detection component is greater than 0. When the voltage sensed by the sixth detection component is greater than 0, the sixth detection component detects that the seat belt is in an intact state.

[0047] Specifically, the conductive wire is formed by twisting multiple strands of thin copper wire. This structure increases the flexibility of the conductive wire and is more suitable for use in situations where frequent movement or bending is required. By observing whether the voltage sensed by the sixth detection component is greater than 0, it can be determined whether the wire is damaged, and then whether the seat belt is in an intact state, so that the seat belt can be replaced in time according to the detection results of the sixth detection component.

[0048] In this embodiment, the safety belt has multiple safety buckles, and there are multiple safety buckle detection elements, and the multiple safety buckle detection elements are arranged in a one-to-one correspondence with the multiple safety buckles; and / or, a second magnetic element is arranged in the lock tongue of each safety buckle, and a safety buckle detection element is arranged in the lock shell of each safety buckle, and the safety buckle detection element is a Hall sensor. When the second magnetic element approaches the safety buckle detection element, the output end of the Hall sensor is at a low level, and at this time the safety buckle detection element detects that the safety buckle is in a fastened state; when the second magnetic element is away from the safety buckle detection element, the output end of the Hall sensor is at a high level, and at this time the safety buckle detection element detects that the safety buckle is in a separated state.

[0049] Specifically, by observing whether the output terminal of the Hall sensor is at a low level or a high level, it can be determined whether the second magnetic member approaches or departs from the safety buckle detection member, and further whether the safety buckle is fully fastened, that is, it can be determined whether the lock tongue and the lock case are in a fastened state or a separated state, ensuring the detection reliability of the sixth detection member for whether the safety buckle is in a fastened state.

[0050] In this embodiment, the safety rope control system further includes a controller. The first detection component, the second detection component, and the third detection component are all communicatively connected to the controller, and the controller is communicatively connected to the lock body 3, so as to feed back the detection results of the first detection component, the second detection component, and the third detection component to the controller, so that the controller controls the lock body 3 to switch between the open state and the closed state.

[0051] Specifically, the controller is configured to control the lock body 3 to switch between the open state and the closed state according to the detection results of the first detection component, the second detection component, and the third detection component.

[0052] In specific implementation, the first detection component, the second detection component, and the third detection component can all transmit signals to the controller in the ways of LoRa, NB-loT, and radio frequency (RF) transmission.

[0053] In specific implementation, the controller first determines the types and measurement parameters of each detection component, and then sets the upper threshold Tupper and the lower threshold Tlower. These thresholds should be determined according to specific safety standards, equipment specifications, and actual application requirements, and are expressed by the formula: Tupper ≤ safety range ≤ Tlower; then initialize and calibrate each detection component, and perform correct installation and connection according to the instructions of each detection component; perform necessary calibration operations to ensure the measurement accuracy of each detection component; the controller obtains the detection results of each detection component, filters the obtained detection results to remove noise and outliers; unit conversion or data normalization may be required to meet the requirements of subsequent comparisons; then the controller calculates the difference D = M - Tmiddle, where Tmiddle = (Tupper + Tlower) / 2; if D > 0 and M > Tupper, it is determined as a dangerously high state; if D < 0 and M < Tlower, it is determined as a dangerously low state; if Tlower ≤ M ≤ Tupper, it is determined as a safe state; then the controller outputs the safety state information in a clear manner according to the comparison results; for example, display words such as "safe", "dangerously high", "dangerously low", etc., or give prompts through indicator lights of different colors, sound alarms, etc.; the controller continuously monitors the working state of the operator and the usage state of the rope body 2, and updates the thresholds in a timely manner when the threshold range needs to be adjusted (such as equipment aging, environmental changes, etc.).

[0054] Specifically, the controller can also be used to determine the identity status of the operator, and the Bluetooth module in the controller is initialized, including setting the Bluetooth name, visibility, and communication parameters; the operator's mobile device (such as a mobile phone) searches for nearby Bluetooth devices, finds the controller and pairs it, and after successful pairing, establishes a Bluetooth connection; the mobile device sends data containing authentication information to the controller via Bluetooth, such as user account, password, encrypted token, etc.; the controller receives the authentication information from the mobile device, decrypts and verifies the received information (if encrypted), and compares it with the locally stored legitimate user information; the controller makes an unlocking decision based on the verification result, and if the verification is successful, sends an identity authentication pass instruction.

[0055] Specifically, the controller controls the lock body 3 to switch between the open state and the closed state based on the detection results of the first detection component, the second detection component and the third detection component and the identity status of the operator. The lock body 3 will switch to the open state when the first detection component and the second detection component both detect that the operator is in a normal working state, the third detection component detects that the rope body 2 is in a safe use state, and the controller determines that the identity authentication of the operator is passed.

[0056] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0057] The safety rope control system of the present invention includes a box 7, a first detection component, a safety helmet, a second detection component, a safety belt and a third detection component. A rope body 2 is provided in the inner cavity of the box 7, a connecting buckle 8 is provided at the first end of the rope body 2, and a connecting hook 1 is provided at the second end of the rope body 2. A lock body 3 is provided on the box 7, and the lock body 3 has an open state for opening the box 7 and a closed state for closing the box 7. The first detection component detects the working state of the operator wearing the safety helmet, the second detection component detects the working state of the operator wearing the safety belt, and the third detection component detects the use state of the rope body 2. Only when the first detection component and the second detection component both detect that the operator is in a normal working state and the third detection component detects that the rope body 2 is in a safe use state, the lock body 3 will switch to the open state, so that the rope body 2 can be taken out of the box 7, so that the operator can use the rope body 2, thereby preventing the operator from using the safety rope improperly, thereby solving the problem that the safety rope detection device in the prior art cannot timely stop the behavior of improper use of the safety rope before the construction work begins.

[0058] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.
