Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, functional component, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, functional components, or devices.
[0025] According to an embodiment of the present invention, an embodiment of a method for determining the safety status of a work object is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0026] Figure 1 is a flowchart of a method for determining the safety status of a work object according to an embodiment of the present invention. As shown in Figure 1, the method may include the following steps:
[0027] Step S101: Obtain the resistance data of the safety device.
[0028] In the technical solution provided in step S101 of the present invention, the safety device is used to ensure that the work object is in a safe state, and the safety device can be at least a safety belt. The work object can also be referred to as a high-altitude work object.
[0029] In this embodiment, the resistance data of the safety device is acquired. For example, the resistance data of the safety device is acquired through a seat belt tension sensor. This is merely an example and does not limit the specific method for acquiring the resistance data of the safety device.
[0030] For example, a seatbelt tension sensor is installed on the seatbelt to detect its tension. Using a resistance strain gauge tension sensor, when the seatbelt is subjected to a certain tension, the sensor's resistance changes; by measuring this change in resistance, the seatbelt tension can be determined.
[0031] Step S102: Based on the resistance data, determine the initial tension data of the safety equipment and obtain the initial movement data of the work object.
[0032] In the technical solution provided by step S102 of the present invention, the initial tension data can also be called seat belt tension, and the initial movement data can also be called acceleration data.
[0033] In this embodiment, after obtaining the resistance data of the safety device in step S101, the initial tension data of the safety device is determined based on the resistance data. For example, the initial tension data of the safety device can be determined by the change value of the resistance data. This is only an exemplary example and does not limit the specific method for determining the initial tension data of the safety device.
[0034] For example, the relationship between the resistance change and tension of a resistance strain gauge tension sensor can be expressed by the following formula: ΔR = kF
[0035] In this context, ΔR represents the change in sensor resistance, indicating how the sensor resistance changes relative to its initial resistance under varying seatbelt tension. k is the sensor's sensitivity coefficient, reflecting its sensitivity to changes in seatbelt tension; different sensor models have different sensitivity coefficients. F is the seatbelt tension, i.e., the pulling force acting on the seatbelt. By measuring the sensor's resistance change, the seatbelt tension can be calculated.
[0036] Optionally, after determining the initial tension data of the safety device, the initial movement data of the work object is acquired. For example, the initial movement data of the work object can be acquired through an accelerometer. This is merely an example and does not limit the specific method for acquiring the initial movement data of the work object.
[0037] Step S103: Based on the initial movement data and initial tension data, monitor the state of the work object and obtain the monitoring results.
[0038] In the technical solution provided by step S103 of the present invention, the monitoring result is used to indicate whether the work object is in a safe state or in a dangerous state.
[0039] In this embodiment, after determining the initial tension data of the safety device and obtaining the initial movement data of the work object in step S102, the initial movement data and the initial tension data are used to monitor the state of the work object and obtain the monitoring results.
[0040] Optionally, monitoring data is obtained by comparing the initial tension data with a first tension threshold and a second tension threshold, and the status of the work object is monitored based on the monitoring data to obtain monitoring results.
[0041] Optionally, when the initial tension data is less than the first tension threshold, or when the initial tension data is greater than the second tension threshold, it indicates that the worker is likely to be in a dangerous situation. Based on this, an initial movement value is extracted from the initial movement data, wherein the first tension threshold is less than the second tension threshold.
[0042] For example, when the initial tension data is less than a first tension threshold and the initial movement value is greater than a first movement threshold, first monitoring data is acquired. This first monitoring data indicates the time interval for monitoring the safety equipment and the work object. The first tension threshold can be F. min =50N, the first moving threshold can be a max =2m / s 2 The first monitoring data can be the time interval T1 = 2s.
[0043] For another example, when the initial tension data is less than a first tension threshold and the initial movement value is less than a second movement threshold, second monitoring data is acquired, wherein the time interval corresponding to the second monitoring data is greater than the time interval corresponding to the first monitoring data. Therefore, based on either the first or second monitoring data, the second movement threshold can be 'a'. min = -2m / s 2 The second monitoring data can be the time interval T2 = 2s.
[0044] Optionally, after determining the monitoring data, the safety equipment and the work object are monitored based on the monitoring data to obtain target tension data and target movement value, and then the monitoring results of the work object are determined based on the target tension data and target movement value.
[0045] For example, when the monitoring data is the first monitoring data, the target tension data is less than the first tension threshold, and the target movement value is greater than the first movement threshold, it can be determined that the monitoring result of the work object is that the work object is in a dangerous state.
[0046] Step S104: In response to the monitoring result indicating that the work object is in a dangerous state, output hazard information.
[0047] In the technical solution provided by step S104 of the present invention, the danger information is used to indicate that the work object is in a dangerous state, and the monitoring result can also be called the judgment result.
[0048] In this embodiment, after obtaining the monitoring result in step S103, when the monitoring result indicates that the work object is in a dangerous state, a hazard information is output.
[0049] For example, if the judgment result is that the seat belt has lost its protective function, the control module will immediately trigger the alarm module to issue an audible and visual alarm to remind the workers and managers to pay attention to safety.
[0050] It should be noted that the above embodiments can be executed by a device for determining the safety status of the work object.
[0051] In steps S101 to S104 of this invention, resistance data of a safety device is acquired, wherein the safety device is used to ensure the work object is in a safe state; based on the resistance data, initial tension data of the safety device is determined, and initial movement data of the work object is acquired; based on the initial movement data and initial tension data, the state of the work object is monitored to obtain a monitoring result, wherein the monitoring result indicates whether the work object is in a safe state or a dangerous state; in response to the monitoring result indicating that the work object is in a dangerous state, a hazard information is output, wherein the hazard information is used to indicate that the work object is in a dangerous state. In other words, this invention monitors the state of the work object using the initial tension data and initial movement data of the safety device, and when the monitoring result indicates that the work object is in a dangerous state, it promptly outputs a hazard information, ensuring timely determination of whether the worker at height has lost the protection of the safety device, thereby solving the technical problem of being unable to determine the safety state of the work object and achieving the technical effect of timely determination of the safety state of the work object.
[0052] The method described in this embodiment will be further described below.
[0053] As an optional embodiment, the state of the work object is monitored based on initial movement data and initial tension data to obtain monitoring results, including: in response to the initial tension data being less than a first tension threshold or the initial tension data being greater than a second tension threshold, an initial movement value is extracted from the initial movement data, wherein the first tension threshold is less than the second tension threshold; and the state of the work object is monitored based on the initial tension data and the initial movement value to obtain monitoring results.
[0054] In this embodiment, when the initial tension data is less than a first tension threshold or greater than a second tension threshold, an initial movement value is extracted from the initial movement data. For example, the current tension value of the seat belt can be calculated according to the seat belt tension calculation formula, thereby determining the first tension threshold and the second tension threshold. This is merely an illustrative example and does not limit the specific methods for determining the first tension threshold and the second tension threshold.
[0055] For example, suppose the first tension threshold is F. min =50N, the second tension threshold is F max =200N, at this time the initial tension data of the seat belt is F=40N. Since 40N<50N, that is, the initial tension data is less than the first tension threshold, based on this, the initial movement value is extracted from the initial movement data.
[0056] Optionally, the state of the work object is monitored based on the initial tension data and initial movement value to obtain the monitoring results. Since the present invention determines the monitoring results by monitoring the state of the work object, it achieves the purpose of timely determining whether the high-altitude worker has lost the protection of the safety equipment.
[0057] As an optional embodiment, the status of the work object is monitored based on initial tension data and initial movement value to obtain monitoring results, including: acquiring first monitoring data in response to the initial tension data being less than a first tension threshold and the initial movement value being greater than the first movement threshold, wherein the first monitoring data is used to indicate the time interval data for monitoring the safety equipment and the work object; acquiring first monitoring data in response to the initial tension data being greater than a second tension threshold and the initial movement value being equal to the second movement threshold, wherein the second movement threshold is less than the first movement threshold; acquiring second monitoring data in response to the initial tension data being less than the first tension threshold and the initial movement value being less than the second movement threshold, wherein the time interval corresponding to the second monitoring data is greater than the time interval corresponding to the first monitoring data; acquiring second monitoring data in response to the initial tension data being greater than the second tension threshold and the initial movement value being greater than the first movement threshold; and monitoring the status of the work object based on the first monitoring data and the second monitoring data to obtain monitoring results.
[0058] In this embodiment, when the initial tension data is less than the first tension threshold and the initial movement value is greater than the first movement threshold, the first monitoring data is acquired, wherein the first monitoring data can be T1 or T2.
[0059] For example, if the calculated seat belt tension F <F min =50N, and acceleration a>a max =2m / s 2 If the time interval is not detected, the time interval determination mechanism is immediately triggered. The time interval T1 = 2s is obtained, and the seat belt tension and acceleration are continuously monitored within this time interval.
[0060] Optionally, when the initial tension data is greater than the second tension threshold and the initial movement value is equal to the second movement threshold, the first monitoring data is acquired.
[0061] For example, the calculated seat belt tension F > F max =200N, and acceleration a min = -2m / s 2 This also immediately triggers the time interval judgment mechanism. The time interval T2 = 2s is obtained, and the seat belt tension and acceleration are continuously monitored within this time interval.
[0062] Optionally, when the initial tension data is less than the first tension threshold and the initial movement value is less than the second movement threshold, second monitoring data is acquired. The second monitoring data can be T3 or T4.
[0063] For example, if the calculated seat belt tension F <F min =50N, and acceleration a min = -2m / s 2 At this point, it is necessary to observe for a period of time to obtain the time interval T3 = 3s.
[0064] Optionally, when the initial tension data is greater than the second tension threshold and the initial movement value is greater than the first movement threshold, the second monitoring data is acquired.
[0065] For example, if the calculated seat belt tension F > F max =200N, and acceleration a>a max =2m / s 2 Similarly, it is necessary to observe for a period of time to obtain the time interval T4 = 3s.
[0066] As an optional embodiment, the status of the work object is monitored based on the first monitoring data and the second monitoring data to obtain monitoring results, including: monitoring the safety equipment and the work object according to the first monitoring data or the second monitoring data to obtain target tension data and target movement value; and determining the monitoring results of the work object based on the target tension data and target movement value.
[0067] In this embodiment, the safety equipment and the work object are monitored according to the first monitoring data or the second monitoring data to obtain target tension data and target movement value; thereby, the monitoring result of the work object is determined based on the target tension data and target movement value. For example, under the first monitoring data, the target tension data and target movement value are obtained by a resistance strain gauge tension sensor and an acceleration sensor, respectively. This is only an exemplary example and does not limit the specific method for obtaining the target tension data and target movement value.
[0068] Optionally, the target tension data can be determined using a resistance strain gauge tension sensor and the aforementioned formula (1), which will not be elaborated here.
[0069] As an optional embodiment, determining the monitoring result of the work object based on the target tension data and the target movement value includes: in response to the monitoring data being the first monitoring data, the target tension data being less than a first tension threshold, and the target movement value being greater than a first movement threshold, determining the monitoring result of the work object as the work object being in a dangerous state; in response to the monitoring data being the first monitoring data, the target tension data being greater than a second tension threshold, and the target movement value being less than a second movement threshold, determining the monitoring result of the work object as the work object being in a dangerous state.
[0070] In this embodiment, when the monitoring data is the first monitoring data, the target tension data is less than the first tension threshold, and the target movement value is greater than the first movement threshold, it can be determined that the monitoring result of the work object is that the work object is in a dangerous state.
[0071] For example, if the target tension of the seatbelt is always less than 50N and the target acceleration is always greater than 2m / s² throughout the entire time interval T1. 2 If the safety belt fails to provide protection, it can be determined that the monitoring results of the work object indicate that the work object is in a dangerous state.
[0072] Optionally, when the monitoring data is the first monitoring data, the target tension data is greater than the second tension threshold, and the target movement value is less than the second movement threshold, the monitoring result of the work object is determined to be that the work object is in a dangerous state.
[0073] For example, if the seatbelt tension is always greater than 200N and the acceleration is always less than -2m / s² throughout the entire time interval T2... 2 If the safety belt fails to provide protection and the person falls rapidly, it can be determined that the monitoring results of the work object indicate that the work object is in a dangerous state.
[0074] As an optional embodiment, the method for determining the safety status of the work object further includes: in response to the monitoring data being second monitoring data, the target tension data being less than a first tension threshold, or the target movement value being less than a second movement threshold, determining that the monitoring result of the work object is that the work object is in a dangerous state; in response to the monitoring data being second monitoring data, the target tension data being greater than the first tension threshold, or the target movement value being greater than the first movement threshold, determining that the monitoring result of the work object is that the work object is in a dangerous state.
[0075] In this embodiment, when the monitoring data is the second monitoring data, the target tension data is less than the first tension threshold, or the target movement value is less than the second movement threshold, it can be determined that the monitoring result of the work object is that the work object is in a dangerous state.
[0076] For example, if the seatbelt tension remains less than 50 or the acceleration remains less than -2 m / s² within time interval T3. 2 If the safety belt fails to provide protection, it is determined that the monitoring results of the work object indicate that the work object is in a dangerous state.
[0077] Optionally, when the monitoring data is the second monitoring data, the target tension data is greater than the first tension threshold, or the target movement value is greater than the first movement threshold, the monitoring result of the work object can be determined to be that the work object is in a dangerous state.
[0078] For example, if the seatbelt tension remains greater than 200N or the acceleration remains greater than 2m / s² within time interval T4. 2 If the safety belt fails to provide protection, it is determined that the monitoring results of the work object indicate that the work object is in a dangerous state.
[0079] It should be noted that the above embodiments can be executed by a device for determining the safety status of the work object.
[0080] In this embodiment, resistance data of a safety device is acquired, wherein the safety device is used to ensure the work object is in a safe state; based on the resistance data, initial tension data of the safety device is determined, and initial movement data of the work object is acquired; based on the initial movement data and initial tension data, the state of the work object is monitored to obtain a monitoring result, wherein the monitoring result indicates whether the work object is in a safe state or in a dangerous state; in response to the monitoring result indicating that the work object is in a dangerous state, a hazard information is output, wherein the hazard information is used to alert the work object to a dangerous state. In other words, this invention monitors the state of the work object using the initial tension data and initial movement data of the safety device, and when the monitoring result indicates that the work object is in a dangerous state, it promptly outputs a hazard information, ensuring timely determination of whether the worker at height has lost the protection of the safety device, thereby solving the technical problem of being unable to determine the safety state of the work object and achieving the technical effect of timely determination of the safety state of the work object.
[0081] The technical solutions of the embodiments of the present invention will be illustrated below with reference to preferred embodiments.
[0082] Currently, safety belts are crucial equipment for protecting the lives of workers engaged in high-altitude operations. They serve as the last line of defense for worker safety. Monitoring and determining the status of safety equipment is a critical step in ensuring worker safety.
[0083] In related technologies, due to various reasons, workers may unexpectedly lose the protection of safety equipment during operations, posing a significant safety risk. Currently, there is a lack of a method to promptly and accurately determine whether workers at height have lost the protection of their safety equipment. Therefore, there is a technical problem of being unable to determine the safety status of the work object. No effective solution has yet been proposed to address this technical problem of being unable to determine the safety status of the work object.
[0084] However, this invention proposes a method for determining the safety belt protection during high-altitude operations. This method involves real-time detection of the safety belt tension and the worker's acceleration, transmitting the detected signals to a signal processing module. The signal processing module processes and analyzes the sensor signals, calculates the safety belt tension and the worker's acceleration, and determines whether the safety belt is in normal working order and whether the worker is in normal motion. If the determination indicates that the safety belt has lost its protective function, the control module triggers an alarm module to issue an alarm. This solves the technical problem of being unable to determine the safety status of the work object and achieves the technical effect of timely determination of the safety status of the work object.
[0085] The embodiments of the present invention will be further described below.
[0086] Figure 2 is a flowchart of a method for determining the protection of safety belts in high-altitude operations according to an embodiment of the present invention. The analysis method includes the following steps:
[0087] Step S201: Determine the seat belt tension.
[0088] In this embodiment, for a resistance strain gauge tension sensor, the relationship between its resistance change and tension can be expressed by the aforementioned formula, which will not be repeated here.
[0089] Optionally, the initial resistance of the sensor is set to R0 = 100Ω, and the measured resistance is R. Then, the resistance change ΔR = R - R0. Let the sensor's sensitivity coefficient k = 0.50Ω / N. Substituting this into the above formula, the seatbelt tension can be obtained.
[0090] Step S202: Determine the acceleration of the operator.
[0091] In this embodiment, the worker's acceleration is determined based on an acceleration sensor.
[0092] Optionally, accelerometers typically output analog voltage signals, the relationship of which to acceleration can be determined by the sensor's sensitivity. Let the sensitivity of the accelerometer be m = 0.1 m / s². 2 / V represents the magnitude of acceleration per unit output voltage. If the output voltage is V, then the acceleration a = v / 0.1.
[0093] Step S203: Determine the safety status of the worker based on the tension of the safety belt and the acceleration of the worker, and take corresponding actions.
[0094] In this embodiment, the normal range value for seat belt tension is set to [F]. min ,F max The range is defined as [50N, 200N], based on the following: Extensive practical testing and data analysis of various types of safety belts under normal use revealed that when the tension on the safety belt exceeds 50N, it effectively ensures the safety of workers and prevents loosening due to insufficient tension. Furthermore, when the tension does not exceed 200N, the material and structure of the safety belt can withstand this force without breakage. Therefore, the normal range is set between 50N and 200N.
[0095] Optionally, the normal range value for acceleration is set to [a]. min ,a max ] = [-2m / s 2 2m / s 2 The rationale is as follows: When workers are performing normal work at heights, their acceleration generally does not exceed ±2 m / s². When the acceleration is less than -2 m / s², it may mean that the worker is in an abnormal state such as rapid descent; when the acceleration is greater than 2 m / s², it may mean that the worker has experienced sudden acceleration, such as a fall.
[0096] Optionally, the specific judgment method is as follows: if the calculated seat belt tension F <F min =50N, and acceleration a>a max =2m / s 2 If this happens, the time interval judgment mechanism is immediately triggered. A time interval T1 = 2s is set, and the seat belt tension and acceleration are continuously monitored within this time interval.
[0097] Optionally, if the seatbelt tension is always less than 50 N and the acceleration is always greater than 2 m / s² throughout the entire time interval T1. 2 If the seatbelt fails to provide protection, the control module will trigger the alarm module to sound an alarm. The 2-second time interval is set to avoid false alarms caused by momentary interference signals, giving the system sufficient time to confirm whether the abnormal situation persists.
[0098] Alternatively, if the calculated seat belt tension F > F max =200N, and acceleration a min = -2m / s 2Similarly, the judgment time interval mechanism is triggered immediately. A time interval T2 = 2s is set, and the seat belt tension and acceleration are continuously monitored within this time interval.
[0099] Optionally, if the seatbelt tension is always greater than 200 N and the acceleration is always less than -2 m / s² throughout the entire time interval T2. 2 If the seatbelt fails to provide protection and the person falls rapidly, the control module will trigger the alarm module to issue an alarm.
[0100] Optionally, if the calculated seat belt tension F <F min =50N, and acceleration a min = -2m / s 2 At this point, further observation is needed for a period of time, set at a time interval T3 = 3 seconds. If, within this time interval T3, the seatbelt tension remains less than 50 or the acceleration remains less than -2 m / s², then... 2 If the safety belt fails to provide protection, an alarm will be triggered. The 3-second time interval is to account for situations where the worker may be in a relatively complex state of motion, requiring a slightly longer time for accurate judgment.
[0101] Alternatively, if the calculated seat belt tension F > F max =200N, and acceleration a>a max =2m / s 2 Similarly, further observation is needed for a period of time, set at a time interval T4 = 3 seconds. If, within this time interval T4, the seatbelt tension remains greater than 200 N or the acceleration remains greater than 2 m / s², then... 2 If the seatbelt fails to provide protection, an alarm will be triggered.
[0102] Figure 3 is a schematic diagram of a high-altitude work safety belt protection judgment device according to an embodiment of the present invention. The high-altitude work safety belt protection judgment device 300 includes: a safety belt tension sensor 301, an acceleration sensor 302, a signal processing module 303, an alarm module 304, and a control module 305.
[0103] In this embodiment, a seatbelt tension sensor 301 is installed on the seatbelt to detect its tension. When the seatbelt is in normal use, the tension sensor outputs a signal value within a certain range. A resistance strain gauge tension sensor is used; when the seatbelt is subjected to a certain tension, the sensor's resistance changes, and the tension of the seatbelt can be determined by measuring this change in resistance.
[0104] Accelerometer 302, mounted on the worker's body or safety belt, is used to detect the worker's acceleration. When the worker is stationary or in normal motion, the accelerometer outputs a signal value within a certain range. If the worker suddenly falls or experiences an abnormal situation, the output value of the accelerometer will change significantly.
[0105] The signal processing module 303 receives signals from the seatbelt tension sensor and the accelerometer, and processes and analyzes them. It employs techniques such as filtering, amplification, and analog-to-digital conversion to convert the sensor signals into digital signals for processing by the control module. A low-pass filter removes high-frequency noise from the sensor signals, then an amplifier amplifies the signals to an appropriate amplitude, and finally, an analog-to-digital converter converts the analog signals into digital signals.
[0106] The alarm module 304 includes an audible and visual alarm, etc. When the signal processing module determines that the seat belt has lost its protective function, the control module triggers the alarm module to issue an alarm.
[0107] The control module 305 is connected to the seat belt tension sensor, acceleration sensor, signal processing module and alarm module respectively, coordinates the work of each module, determines whether the seat belt has lost its protective function based on the sensor signals, and controls the operation of the alarm module.
[0108] Optionally, an installation device is used to install the safety belt tension sensor on the safety belt, the acceleration sensor on the worker or the safety belt, and the signal processing module 303, alarm module 304 and control module 305 are installed in appropriate positions to ensure that the connection between each module is stable and reliable.
[0109] Optionally, the device is debugged to ensure that all modules, including the seat belt tension sensor, acceleration sensor, signal processing module 303, alarm module 304, and control module 305, are functioning properly. The normal range values for seat belt tension and acceleration are set, i.e., F is determined. min =50N, F max =200N, a min = -2m / s 2 a max =2m / s 2 The values of T1 = 2s, T2 = 2s, T3 = 3s, and T4 = 3s are determined simultaneously.
[0110] Optionally, the device monitors the status of the safety belt. During high-altitude operations, the device monitors the tension of the safety belt and the acceleration of the worker in real time. If, according to the calculation formula, the safety belt tension is outside the normal range and the acceleration exceeds the normal range, the device promptly activates the judgment time interval mechanism. Within the corresponding time interval, it continuously monitors and determines whether the safety belt has lost its protective function based on the monitoring results. If it is determined that the safety belt has lost its protective function, an alarm is issued in a timely manner.
[0111] In this embodiment, the tension of the safety belt and the acceleration of the worker are detected in real time, and the detected signals are transmitted to the signal processing module. The signal processing module processes and analyzes the sensor signals, calculates the tension of the safety belt and the acceleration of the worker, and determines whether the safety belt is in normal working condition and whether the worker is in normal motion. If the determination result is that the safety belt has lost its protective function, the control module triggers the alarm module to issue an alarm, thus solving the technical problem of being unable to determine the safety status of the work object and achieving the technical effect of timely determination of the safety status of the work object.
