[0022] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0024] 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 of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0025] Figure 1 is a flow chart of a method for determining a safety status of a work object according to an embodiment of the present invention. Figure 1 As shown, the method may include the following steps:

[0026] Step S101, obtaining resistance data of a safety device.

[0027] In the technical solution provided in the above step S101 of the present invention, the safety device is used to put the working object in a safe state, and the safety device can at least be a safety belt. The working object can also be called an aerial working object.

[0028] In this embodiment, the resistance data of the safety device is obtained, for example, by using a seat belt tension sensor, which is only an example and does not limit the specific method of obtaining the resistance data of the safety device.

[0029] For example, a seat belt tension sensor is installed on a seat belt to detect the tension of the seat belt. Using a resistance strain type tension sensor, when the seat belt is subjected to a certain tension, the resistance of the sensor changes, and the tension of the seat belt can be determined by measuring the change in resistance.

[0030] Step S102: determining initial tension data of the safety device based on the resistance data, and acquiring initial movement data of the working object.

[0031] In the technical solution provided in the above step S102 of the present invention, the initial tension data may also be referred to as seat belt tension, and the initial movement data may also be referred to as acceleration data.

[0032] In this embodiment, after the resistance data of the safety device is acquired in step S101, the initial tension data of the safety device is determined according to the resistance data. For example, the initial tension data of the safety device is determined by the change value of the resistance data. This is only an example and does not limit the specific method of determining the initial tension data of the safety device.

[0033] For example, the relationship between the resistance change and tension of a resistive strain gauge tension sensor can be expressed by the following formula:

[0034] ΔR=kF

[0035] Among them, ΔR is the change in sensor resistance, which indicates the change in sensor resistance relative to the initial resistance when the seat belt is subjected to different tensions. k is the sensitivity coefficient of the sensor, which reflects the sensitivity of the sensor to changes in seat belt tension. Different sensor models have different sensitivity coefficients. F is the tension of the seat belt, that is, the magnitude of the pulling force on the seat belt. By measuring the change in sensor resistance, the tension of the seat belt can be calculated.

[0036] Optionally, after determining the initial tension data of the safety device, the initial movement data of the operating object is obtained, for example, by using an acceleration sensor, which is only an example and does not limit the specific method of obtaining the initial movement data of the operating object.

[0037] Step S103: Based on the initial movement data and the initial tension data, the state of the working object is monitored to obtain a monitoring result.

[0038] In the technical solution provided in the above step S103 of the present invention, the monitoring result is used to indicate that the operation object is in a safe state or the operation object is in a dangerous state.

[0039] In this embodiment, after the initial tension data of the safety device is determined in step S102 and the initial movement data of the working object is acquired, the initial movement data and the initial tension data are used to monitor the state of the working object to obtain a monitoring result.

[0040] Optionally, the initial tension data is compared with the first tension threshold and the second tension threshold to obtain monitoring data, thereby monitoring the state of the working object according to the monitoring data to obtain a monitoring result.

[0041] Optionally, when the initial tension data is less than the first tension threshold, or the initial tension data is greater than the second tension threshold, it indicates that the operator is prone to being in a dangerous state. Based on this, the 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 the first tension threshold value, and the initial movement value is greater than the first movement threshold value, the first monitoring data is obtained, wherein the first monitoring data is used to indicate the time interval data for monitoring the safety device and the operation object, and the first tension threshold value can be F min =50N, the first moving threshold can be a max =2m / s 2 , the first monitoring data may be a time interval T1 = 2s.

[0043] For another example, when the initial tension data is less than the first tension threshold and the initial movement value is less than the second movement threshold, the second monitoring data is obtained, wherein the time interval corresponding to the second monitoring data is greater than the time interval corresponding to the first monitoring data. Thus, according to the first monitoring data or the second monitoring data, the second movement threshold can be a min =-2m / s 2 , the second monitoring data may be a time interval T2=2s.

[0044] Optionally, after the monitoring data is determined, the safety equipment and the operating object are monitored according to the monitoring data to obtain target tension data and target movement value, thereby determining the monitoring result of the operating object according to 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 operation object is that the operation object is in a dangerous state.

[0046] Step S104: in response to the monitoring result that the working object is in a dangerous state, output danger information.

[0047] In the technical solution provided in the above step S104 of the present invention, the danger information is used to prompt that the working object is in a dangerous state, wherein the monitoring result can also be called a judgment result.

[0048] In this embodiment, after the monitoring result is obtained in step S103, when the monitoring result indicates that the operation object is in a dangerous state, the danger information is output.

[0049] For example, if the judgment result is that the seat belt has lost its protective function, the control module immediately triggers the alarm module to send out an audible and visual alarm to remind operators 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 an operation object.

[0051] In the above steps S101 to S104 of the present invention, the resistance data of the safety device is obtained, wherein the safety device is used to put the working object in a safe state; based on the resistance data, the initial tension data of the safety device is determined, and the initial movement data of the working object is obtained; based on the initial movement data and the initial tension data, the state of the working object is monitored to obtain a monitoring result, wherein the monitoring result is used to indicate that the working object is in a safe state or the working object is in a dangerous state; in response to the monitoring result that the working object is in a dangerous state, danger information is output, wherein the danger information is used to prompt that the working object is in a dangerous state. In other words, the present invention monitors the state of the working object through the initial tension data and initial movement data of the safety device, and when the monitoring result shows that the working object is in a dangerous state, the danger information is output in time, which ensures the purpose of timely judging whether the high-altitude working personnel have lost the protection of the safety device, thereby solving the technical problem of being unable to determine the safety state of the working object, and achieving the technical effect of timely determining the safety state of the working object.

[0052] The above method of this embodiment is further introduced below.

[0053] As an optional implementation method, the state of the working object is monitored based on the initial movement data and the initial tension data to obtain a monitoring result, 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, extracting an initial movement value from the initial movement data, wherein the first tension threshold is less than the second tension threshold; based on the initial tension data and the initial movement value, the state of the working object is monitored to obtain a monitoring result.

[0054] In this embodiment, when the initial tension data is less than the first tension threshold, or the initial tension data is greater than the second tension threshold, the initial movement value is extracted from the initial movement data. For example, the current seat belt tension value can be calculated according to the seat belt tension calculation formula to determine the first tension threshold and the second tension threshold. This is only an example, and the specific determination method of the first tension threshold and the second tension threshold is not limited.

[0055] For example, assuming that 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 working object is monitored according to the initial tension data and the initial movement value to obtain a monitoring result. Since the present invention determines the monitoring result by monitoring the state of the working object, it achieves the purpose of timely judging whether the height workers have lost the protection of safety equipment.

[0057] As an optional implementation method, based on the initial tension data and the initial movement value, the state of the working object is monitored to obtain a monitoring result, including: 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, first monitoring data is obtained, wherein the first monitoring data is used to indicate the time interval data for monitoring the safety device and the working object; 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, first monitoring data is obtained, wherein the second movement threshold is less than the first movement threshold; 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, second monitoring data is obtained, wherein the time interval corresponding to the second monitoring data is greater than the time interval corresponding to the first 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, second monitoring data is obtained; based on the first monitoring data and the second monitoring data, the state of the working object is monitored to obtain a monitoring result.

[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 may 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 , then the judgment time interval mechanism is triggered immediately. The time interval T1 = 2s is obtained, and the seat belt tension and acceleration are continuously monitored during 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 , and the time interval determination mechanism is also triggered immediately. The time interval T2 = 2s is obtained, and the seat belt tension and acceleration are continuously monitored during 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, the second monitoring data is acquired, wherein the second monitoring data may 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 time, further observation is required 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 , it is also necessary to further observe for a period of time and obtain the time interval T4 = 3s.

[0066] ​As an optional implementation method, the state of the working object is monitored based on the first monitoring data and the second monitoring data to obtain a monitoring result, including: monitoring the safety equipment and the working object according to the first monitoring data or the second monitoring data to obtain target tension data and target movement value; determining the monitoring result of the working object based on the target tension data and the target movement value.

[0067] In this embodiment, the safety device and the operating object are monitored according to the first monitoring data or the second monitoring data to obtain target tension data and target movement value; thus, the monitoring result of the operating object is determined according to the target tension data and the target movement value. For example, under the first monitoring data, the target tension data and the target movement value are obtained by the resistive strain tension sensor and the acceleration sensor, respectively. This is only an illustrative example, and the specific method for obtaining the target tension data and the target movement value is not limited.

[0068] Optionally, the target tension data can be determined by a resistive strain type tension sensor and the aforementioned formula (1), which will not be described in detail here.

[0069] As an optional implementation method, based on the target tension data and the target movement value, the monitoring result of the operating object is determined, including: in response to the monitoring data being 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, determining that the monitoring result of the operating object is that the operating object is in a dangerous state; in response to the monitoring data being 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, determining that the monitoring result of the operating object is that the operating object is 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 operating object is that the operating object is in a dangerous state.

[0071] For example, if during the entire time interval T1, the target tension of the seat belt is always less than 50N and the target acceleration is always greater than 2m / s 2 , it can be determined that the safety belt has lost its protective function, that is, it can be determined that the monitoring result of the operating object is that the operating 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, it is determined that the monitoring result of the operating object is that the operating object is in a dangerous state.

[0073] For example, if during the entire time interval T2, the seat belt tension is always greater than 200N and the acceleration is always less than -2m / s 2, it can be determined that the safety belt has lost its protective effect and the person has fallen rapidly, that is, it can be determined that the monitoring result of the operating object is that the operating object is in a dangerous state.

[0074] As an optional implementation manner, the method for determining the safety status of the operating object also includes: in response to the monitoring data being the second monitoring data, the target tension data being less than the first tension threshold, or the target movement value being less than the second movement threshold, determining that the monitoring result of the operating object is that the operating object is in a dangerous state; in response to the monitoring data being the 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 operating object is that the operating 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 operating object is that the operating object is in a dangerous state.

[0076] For example, if within time interval T3, the seat belt tension is continuously less than 50 or the acceleration is continuously less than -2m / s 2 , it is judged that the safety belt has lost its protective function, that is, it is determined that the monitoring result of the operating object is that the operating 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, it can be determined that the monitoring result of the operating object is that the operating object is in a dangerous state.

[0078] For example, if within time interval T4, the seat belt tension is continuously greater than 200N or the acceleration is continuously greater than 2m / s 2 , it is judged that the safety belt has lost its protective function, that is, it is determined that the monitoring result of the operating object is that the operating 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 an operation object.

[0080] In this embodiment, the resistance data of the safety device is obtained, wherein the safety device is used to put the working object in a safe state; based on the resistance data, the initial tension data of the safety device is determined, and the initial movement data of the working object is obtained; based on the initial movement data and the initial tension data, the state of the working object is monitored to obtain a monitoring result, wherein the monitoring result is used to indicate that the working object is in a safe state or the working object is in a dangerous state; in response to the monitoring result that the working object is in a dangerous state, danger information is output, wherein the danger information is used to prompt that the working object is in a dangerous state. In other words, the present invention monitors the state of the working object through the initial tension data and initial movement data of the safety device, and when the monitoring result shows that the working object is in a dangerous state, the danger information is output in time, which ensures the purpose of timely judging whether the high-altitude working personnel have lost the protection of the safety device, thereby solving the technical problem of being unable to determine the safety state of the working object, and achieving the technical effect of timely determining the safety state of the working object.

[0081] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0082] At present, safety belts are important equipment to ensure the life safety of workers in aerial work. They are the last line of defense for the life safety of workers. Monitoring and determining the status of safety equipment is a key step to ensure the safety of workers.

[0083] In the related art, due to various reasons, the operator may accidentally lose the protection of the safety equipment during the operation, which brings great safety risks to the operator. At present, there is a lack of a method that can timely and accurately determine whether the high-altitude operator has lost the protection of the safety equipment. Therefore, there is a technical problem that the safety status of the operation object cannot be determined. With respect to the above-mentioned technical problem that the safety status of the operation object cannot be determined, no effective solution has been proposed.

[0084] However, the embodiment of the present invention proposes a method for judging the protection of a safety belt for aerial work, which detects the tension of the safety belt and the acceleration of the operator in real time and transmits the detected signal to the signal processing module. The signal processing module processes and analyzes the sensor signal, calculates the tension of the safety belt and the acceleration of the operator, and judges whether the safety belt is in normal use and whether the operator is in normal motion. If the judgment result is that the safety belt has lost its protective effect, the control module triggers the alarm module to sound an alarm, which solves the technical problem of being unable to determine the safety status of the operating object and achieves the technical effect of timely determining the safety status of the operating object.

[0085] The embodiments of the present invention are further described below.

[0086] Figure 2: is a flow chart of a method for judging the protection of a safety belt for aerial work according to an embodiment of the present invention. The analysis method comprises the following steps:

[0087] Step S201, determining the seat belt tension.

[0088] In this embodiment, for the resistive strain type tension sensor, the relationship between its resistance change and tension can be expressed by the aforementioned formula, which will not be described in detail 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. Assume that the sensitivity coefficient of the sensor is k = 0.5oΩ / N. Substituting it into the above formula, the seat belt tension can be obtained.

[0090] Step S202, determining the acceleration of the operator.

[0091] In this embodiment, the worker acceleration is determined based on an acceleration sensor.

[0092] Optionally, the acceleration sensor usually outputs an analog voltage signal, and the relationship between the analog voltage signal and the acceleration can be determined by the sensitivity of the sensor. Assume that the sensitivity of the acceleration sensor is m = 0.1 m / s 2 / V, which indicates the acceleration corresponding to each unit output voltage. If the output voltage is V, then the acceleration a = v / 0.1.

[0093] Step S203, determining the safety status of the operator according to the seat belt tension and the operator's acceleration and performing corresponding operations.

[0094] In this embodiment, the normal range of seat belt tension is set to [F min ,F max ]=[50N,200N], based on the following: Through a large number of actual tests and data analysis of various types of safety belts under normal use, it is found that when the tension of the safety belt is above 50N, it can better ensure the safety of the operator and will not become loose due to too little tension. When the tension does not exceed 200N, the material and structure of the safety belt can withstand this tension and will not break. Therefore, the normal range is set in the range of 50N to 200N.

[0095] Optionally, set the normal range of acceleration to [a min ,a max ]=[-2m / s 2 ,2m / s 2 ], based on the following: Considering that when workers are working normally at high altitudes, their acceleration generally does not exceed plus or minus 2m / s 2This range. When the acceleration is less than -2m / s 2 When the acceleration is greater than 2m / s 2 When the operator experiences a sudden acceleration, such as a fall, etc.

[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 , the judgment time interval mechanism is triggered immediately. Set a time interval T1 = 2s, and continuously monitor the seat belt tension and acceleration during this time interval.

[0097] Optionally, if during the entire time interval T1, the seat belt tension is always less than 50N and the acceleration is always greater than 2m / s 2 , it can be determined that the seat belt has lost its protective function, and the control module triggers the alarm module to sound an alarm. The time interval of 2s is set to avoid false alarms due to instantaneous interference signals and give the system a certain amount of time to confirm whether the abnormal situation persists.

[0098] Optionally, if the calculated seat belt tension F>F max =200N, and acceleration a min =-2m / s 2 , and the judgment time interval mechanism is also triggered immediately. A time interval T2 = 2s is set, and the seat belt tension and acceleration are continuously monitored during this time interval.

[0099] Optionally, if during the entire time interval T2, the seat belt tension is always greater than 200N and the acceleration is always less than -2m / s 2 , it can be judged that the safety belt has lost its protective function and the person falls rapidly, and the control module triggers the alarm module to sound an alarm.

[0100] Optionally, if the calculated seat belt tension F <F min =50N, and acceleration a min =-2m / s 2 , at this time, further observation is required for a period of time, and a time interval T3 = 3s is set. If during this time interval T3, the seat belt tension is continuously less than 50 or the acceleration is continuously less than -2m / s 2 , the safety belt is judged to have lost its protective function and an alarm is triggered. The 3s time interval is taken into consideration that in this case the operator may be in a more complex state of motion and it takes a little longer to make an accurate judgment.

[0101] Optionally, if the calculated seat belt tension F>F max ​=200N, and acceleration a>a max =2m / s 2 , and also need to observe for a period of time, set a time interval T4 = 3s. If during this time interval T4, the seat belt tension continues to be greater than 200N or the acceleration continues to be greater than 2m / s 2 , it is judged that the seat belt has lost its protective function and an alarm is triggered.

[0102] Figure 3 300 is a schematic diagram of a safety belt protection judgment device for aerial work according to an embodiment of the present invention. The safety belt protection judgment device 300 for aerial work 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, the seat belt tension sensor 301 is installed on the seat belt to detect the tension of the seat belt. When the seat belt is in normal use, the tension sensor outputs a signal value within a certain range. A resistance strain type tension sensor is used. When the seat belt is subjected to a certain tension, the resistance of the sensor changes. The tension of the seat belt can be determined by measuring the change in resistance.

[0104] The acceleration sensor 302 is mounted on the operator or on the safety belt to detect the acceleration of the operator. When the operator is stationary or in normal motion, the acceleration sensor 302 outputs a signal value within a certain range. If the operator suddenly falls or encounters an abnormal situation, the output value of the acceleration sensor 302 will change significantly.

[0105] The signal processing module 303 receives the signals output by the seat belt tension sensor 301 and the acceleration sensor 302, and processes and analyzes them. The sensor signals are converted into digital signals by using filtering, amplification, analog-to-digital conversion and other technologies so that the control module can process them. A low-pass filter is used to remove high-frequency noise in the sensor signal, and then the signal is amplified to a suitable amplitude by an amplifier, and finally the analog signal is converted into a digital signal by an analog-to-digital converter.

[0106] The alarm module 304 includes an audible and visual alarm, etc. When the signal processing module determines that the seat belt loses its protective function, the control module triggers the alarm module to sound an alarm.

[0107] The control module 305 is connected to the seat belt tension sensor 301, the acceleration sensor 302, the signal processing module 303 and the alarm module 304 respectively, coordinates the work of each module, determines whether the seat belt loses its protective function according to the sensor signal, and controls the work of the alarm module 304.

[0108] Optionally, the installation device is installed, the seat belt tension sensor 301 is installed on the seat belt, the acceleration sensor 302 is installed on the operator or on the seat belt, and the signal processing module 303, the alarm module 304 and the control module 305 are installed in appropriate positions to ensure that the connection between the modules is stable and reliable.

[0109] Optionally, the device is debugged to ensure that the seat belt tension sensor 301, the acceleration sensor 302, the signal processing module 303, the alarm module 304 and the control module 305 are working properly. Set the normal range of seat belt tension and acceleration, that is, determine F min =50N, F max =200N, a min =-2m / s 2 、a max =2m / s 2 The value of , and at the same time determine the values ​​of the judgment time intervals T1 = 2s, T2 = 2s, T3 = 3s, T4 = 3s.

[0110] Optionally, the status of the safety belt is monitored. During the high-altitude operation, the device monitors the tension of the safety belt and the acceleration of the operator in real time. If the safety belt tension is not within the normal range and the acceleration is beyond the normal range according to the calculation formula, the device promptly starts the judgment time interval mechanism, continuously monitors within the corresponding time interval, and judges whether the safety belt has lost its protective function based on the monitoring results. If it is judged that the protection function has been lost, an alarm is issued in time.

[0111] In this embodiment, the tension of the safety belt and the acceleration of the operator are detected in real time, and the detected signal is transmitted to the signal processing module. The signal processing module processes and analyzes the sensor signal, calculates the tension of the safety belt and the acceleration of the operator, and determines whether the safety belt is in normal use and whether the operator is in normal motion. If the judgment result is that the safety belt has lost its protective effect, the control module triggers the alarm module to sound an alarm, which solves the technical problem of being unable to determine the safety status of the operating object and achieves the technical effect of timely determining the safety status of the operating object.
