Description

Technical Field

[0001] The present invention relates to the technical field of monitoring the working state of high-altitude workers, and particularly to a safety belt system and a discrimination method for monitoring the working state of high-altitude workers. Background Art

[0002] According to the "Safety Use Specification for Fall Protection Equipment" (GB / T 23468-2009), when personal safety protection is required in places where there is a risk of falling at a height of 2 m or more from the reference plane of the falling height, a safety belt should be used. At the same time, during the use of the safety belt, the operator should not lose protection and should follow the principle of "hanging high and using low".

[0003] At the power operation site, it is often necessary for operators to work at heights, such as:

[0004] Installation and maintenance of transmission lines: Transmission lines are usually erected at high positions, and workers need to use safety belts and climbing equipment for high-altitude operations;

[0005] Installation and maintenance of wind turbines: The installation and maintenance of wind turbines often need to be carried out at heights of dozens of meters or even hundreds of meters;

[0006] Installation and overhaul of substation equipment: Substations are key links in the power system. Workers need to install and debug equipment at high altitudes and carry out regular inspections to ensure the normal operation of the substation;

[0007] Overhaul of power station boilers: In thermal power stations, the regular overhaul of boilers requires workers to climb to the top and high positions of the boilers for inspection, cleaning and maintenance;

[0008] Maintenance of railway power lines: Railway power supply professionals need to climb power poles for high-altitude operations;

[0009] Inspection of UHV and EHV power grids: Workers need to climb nearly 100-meter-high iron towers and conduct inspections along the conductors.

[0010] During high-altitude operations at different power operation sites, high-fall casualties frequently occur during the processes of climbing poles and transferring working positions. How to monitor the working state of operators and the use of safety belts in real time and standardize the use of safety belts is an important means to ensure the safety of operators.

[0011] Currently, there are existing technical means to monitor the high-altitude operations of workers. On the one hand, the safety belt hook is designed and combined with a pressure sensor to monitor the hanging state of the safety belt. On the other hand, the safety belt and safety rope are designed and combined with technologies such as positioning technology and air pressure sensors to monitor the proper use of the safety belt by workers, and standardize the use of the safety belt.

[0012] Currently, when workers are performing high-altitude operations in the power field, they are in states such as climbing, working at a fixed position, and position transfer. During the climbing process, workers constantly change the hanging position of the safety belt or safety rope. Without considering the climbing state of the workers, there may be a situation where the safety belt loses its protection or fails to give an alarm for "hanging high and using low". During the horizontal position transfer process, when workers change the hanging hook position, there may be false alarms for loss of protection and situations where the safety belt is not "hung high and used low". When a worker slips and falls and is in a suspended state, the safety belt hook has pressure, which will feedback information on the normal use of the safety belt and no alarm information will be sent. The existing technical means for monitoring high-altitude operations of workers do not combine the position and operation state information of workers to judge the use state of the safety belt, resulting in a high possibility of misjudgment, and there are still significant safety risks for workers. Summary of the Invention

[0013] In order to overcome the above problems, the purpose of the present invention is to provide a safety belt system and discrimination method for monitoring the operation state of high-altitude workers, to overcome the deficiencies of the prior art. This safety belt system can monitor the operation state of workers in real time. The discrimination method using this safety belt system combines the working height and the use state of the safety belt to judge the operation state of workers, and further judges whether the workers have lost protection according to the operation state, so as to send corresponding warning information, solve the problem of inaccurate identification of illegal use of the safety belt by a single means, improve the accuracy of monitoring the operation state of workers, and thus ensure the safety of workers.

[0014] The technical solution adopted by the present invention is:

[0015] A safety belt system for monitoring the operation state of high-altitude workers includes an intelligent safety belt and a worker monitoring and warning system. The intelligent safety belt is worn on the worker, and the worker monitoring and warning system monitors the operation state of the worker.

[0016] The intelligent safety belt includes a safety belt, a personnel identification module, an intelligent safety belt hook, a height positioning module, and a dynamic monitoring module.

[0017] The personnel identification module is arranged at the back plate of the safety belt. The personnel identification module contains a Bluetooth chip or an RFID chip, and realizes information communication through Bluetooth or RFID signals.

[0018] The intelligent seat belt hook is installed on the seat belt and includes a pressure sensor, a force-bearing movable unit, and a hook body. The pressure sensor is located at the bottom of the force-bearing movable unit and is movably connected to the hook body.

[0019] The height positioning module is arranged at the seat belt backplate. The height positioning module contains a height positioning chip, and the height positioning chip selects satellite positioning and UWB positioning.

[0020] The dynamic monitoring module includes a personnel dynamic monitoring module and a hook dynamic monitoring module. The dynamic monitoring module performs monitoring based on a positioning chip, an acceleration sensor, and a gyroscope sensor. The personnel dynamic monitoring module is arranged at the seat belt backplate, and the hook dynamic monitoring module is arranged in the intelligent seat belt hook body.

[0021] As a further description of the present invention, the operator monitoring and warning system includes a data processing module, an information communication module, a monitoring and warning module, and an enhanced positioning base station.

[0022] The data processing module includes a data processor and a data interface, and is arranged in a server.

[0023] The information communication module is arranged at the seat belt backplate of the intelligent seat belt and includes a data chip and a signal integration unit. The data chip is used to realize system communication, and the signal integration unit is used to collect and process various information transmitted by the intelligent seat belt.

[0024] The monitoring and warning module is arranged at the seat belt backplate and includes an information warning unit and an acoustic-optic vibration unit. The information warning unit receives the seat belt illegal use information sent by the data processing module and performs remote monitoring and warning, and the acoustic-optic vibration unit is used to prompt the operator on-site.

[0025] The enhanced positioning base station is used to improve the positioning accuracy of the operator. A satellite positioning enhanced base station is adopted outdoors, and a UWB positioning base station is adopted indoors.

[0026] As a further description of the present invention, the intelligent seat belt adopts double hooks on both the left and right sides.

[0027] A method for judging the state of an operator using the above seat belt system includes the following steps:

[0028] The height positioning module in the intelligent seat belt automatically selects the positioning data source according to the signal strength and determines the height information of the operator.

[0029] S01: Judging whether the operator is in a high-altitude operation state.

[0030] If the height of the safety belt in the positioning data is lower than 2m, it is determined that the operator is not working at height at this time, and the pressure sensor and dynamic monitoring module on the intelligent safety belt hook are not activated.

[0031] If the height of the safety belt in the positioning data exceeds 2m, it is determined that the operator is in a high-altitude working state at this time, and the pressure sensor and dynamic monitoring module on the intelligent safety belt hook are in an activated state;

[0032] S02: Judgment on whether the operator is in a protected state during high-altitude work.

[0033] If the height of the safety belt in the positioning data exceeds 2m and there is no pressure signal from the pressure sensor on the intelligent safety belt hook, the operator loses protection at this time, and the data processing module issues an alarm message;

[0034] S03: When in a protected high-altitude working state, the height of the safety belt in the positioning data exceeds 2m and the pressure signal on the pressure sensor is normal, determine which specific working state the operator is in through the activated dynamic monitoring module.

[0035] If the personnel dynamic monitoring module detects that the operator has an upward acceleration, the hook dynamic monitoring module detects that the double hooks alternately have an upward acceleration, and the height information of the positioning chip increases, the operator is in an upward climbing state at this time.

[0036] If the personnel dynamic monitoring module detects that the operator is horizontally stationary or has a horizontal acceleration, the hook dynamic monitoring module detects that the double hooks are in a stationary state, and the position information of the positioning chip does not change, the operator is working at a fixed position at this time.

[0037] If the personnel dynamic monitoring module detects that the operator has a horizontal acceleration, the hook dynamic monitoring module detects that the double hooks alternately have a horizontal acceleration, and the positioning chip has a horizontal displacement change, the operator is in a horizontal position transfer at this time.

[0038] If the personnel dynamic monitoring module detects that the operator has a downward acceleration, the hook dynamic monitoring module detects that the double hooks alternately have a downward acceleration, and the height information of the positioning chip continuously decreases, the operator is in a downward position movement state at this time.

[0039] If the personnel dynamic monitoring module detects that the operator has a downward acceleration, the hook dynamic monitoring module detects that the double hooks simultaneously have a downward acceleration, and the height information of the positioning chip continuously decreases, the operator is in a falling state at this time.

[0040] If the personnel dynamic monitoring module detects that the operator has a short-term downward acceleration and then no downward acceleration, the hook dynamic monitoring module detects no downward acceleration of the double hooks, and there is a pressure signal on the pressure sensor of the intelligent safety belt hook and the pressure exceeds 400N, the personnel is in a suspended falling state at this time;

[0041] S04: Judgment on whether the operator is in a state of hanging low and using high,

[0042] If the height of the safety belt in the positioning data exceeds 2m and the hook dynamic monitoring module detects that the positioning chips of the double hooks are lower than the height of the backplate, the safety belt is in a state of hanging low and using high at this time, and an alarm message is sent.

[0043] As a further description of the present invention, the height positioning module monitors the height information of the operator in real time, the personnel dynamic monitoring module monitors the movement information of the operator, and the hook dynamic monitoring module monitors the information of the intelligent safety belt hook, including the following discrimination results:

[0044] First, when the working height of the operator exceeds 2m and the operator is in a climbing state or a fixed-position working state or a horizontal working position transfer state, and there is no pressure signal on both double hooks, the operator loses protection at this time, and an alarm message is sent;

[0045] Second, when the working height of the operator exceeds 2m and the operator is in a falling state, and the tensile force information on the double hooks gradually increases, the personnel has not lost protection at this time, and an alarm message is sent;

[0046] Third, when the working height of the operator exceeds 2m and the operator is in a static state, and the tensile force of the double hooks is the gravity of the operator, the personnel is in a suspended state at this time, and the personnel has not lost protection, and an alarm message is sent;

[0047] Fourth, when the working height of the operator exceeds 2m and the operator is in a falling state, the acceleration monitored by the acceleration sensor is greater than , when there is no tensile force information on the double hooks and the hook acceleration is greater than , the operator is in a state of falling without protection at this time, and an emergency alarm message is sent.

[0048] Advantages of the present invention:

[0049] The safety belt system for monitoring the working state of high-altitude operators in the present invention includes an intelligent safety belt and a personnel monitoring and warning system. When the operator is working at high altitude, the intelligent safety belt is worn on the body. According to the data on the intelligent safety belt and combined with the personnel monitoring and warning system, the working safety of the operator is protected, and an alarm message is sent in time when protection is lost, ensuring the working safety of high-altitude electric power operators.

[0050] The safety belt system and discrimination method for monitoring the working state of high-altitude workers according to the present invention can monitor the working state of workers in real time. The discrimination method using this safety belt system combines the working height and the use state of the safety belt to judge the working state of the workers. At the same time, it further judges whether the workers lose protection according to the working state and issues corresponding warning information, solving the problem of inaccurate identification of illegal use of safety belts by single means, accurately judging the state of high-altitude workers and the use state of safety belts, solving the problem of insufficient supervision of high-altitude operations by existing video supervision technologies, serving as a supplement to high-altitude operation video supervision, enriching supervision means, improving supervision effects, and ensuring the safety of high-altitude operations.

[0051] The discrimination method using the safety belt system for monitoring the working state of high-altitude workers according to the present invention integrates the state judgment logic and reduces the monitoring false alarm rate. This discrimination method integrates multi-sensor signals and realizes accurate judgment of the state of high-altitude workers through relevant logic algorithms, which can effectively reduce the false alarm situation caused by the lack of personnel state judgment and improve the accuracy of safety belt monitoring.

[0052] The discrimination method using the safety belt system for monitoring the working state of high-altitude workers according to the present invention mainly judges the state of workers. On the one hand, it reduces the psychological burden of high-altitude workers caused by false alarms, improves the safety of high-altitude workers, and at the same time reduces the resistance of workers to the use of monitoring equipment; on the other hand, it can judge states such as workers losing protection, the safety belt not being hung high and used low, workers falling, and workers hanging. Through relevant alarm signals, corresponding reminder and rescue measures can be carried out to ensure the safety of high-altitude operations and the emergency response ability to emergencies.

[0074] As Figures 1 to 6 shown, it shows the specific implementation manner of the present invention:

[0075] Embodiment 1

[0076] A safety belt system for monitoring the working status of high-altitude workers includes an intelligent safety belt 1 and a worker monitoring and warning system 2. The intelligent safety belt 1 is worn on the worker, and the worker monitoring and warning system 2 monitors the working status of the worker.

[0077] In this embodiment, as Figure 1 shown, this safety belt system collects relevant data during the operation of the worker through the intelligent safety belt 1, transmits the data to the personnel detection and warning system 2. This safety belt system protects the working safety of the worker based on the data on the intelligent safety belt 1 and in combination with the worker monitoring and warning system 2, and issues an alarm message in a timely manner when the protection is lost, so as to realize the monitoring of the working status of high-altitude workers and ensure the working safety of high-altitude electric power workers.

[0078] The intelligent safety belt 1 includes a safety belt 11, a personnel identity recognition module 12, an intelligent safety belt hook 13, a height positioning module 14, and a dynamic monitoring module 15;

[0079] The personnel identity recognition module 12 is arranged at the back plate of the safety belt. The personnel identity recognition module 12 contains a Bluetooth chip or an RFID chip and realizes information communication through Bluetooth or RFID signals;

[0080] The intelligent safety belt hook 13 is installed on the safety belt 11 and includes a pressure sensor 131, a force-bearing movable unit 132, and a hook body 133. The pressure sensor 131 is located at the bottom of the force-bearing movable unit 132 and is movably connected to the hook body 133;

[0081] The height positioning module 14 is arranged at the back plate of the safety belt. The height positioning module 14 contains a height positioning chip, and the height positioning chip selects satellite positioning 141 and UWB positioning 142;

[0082] The dynamic monitoring module 15 includes a personnel dynamic monitoring module 151 and a hook dynamic monitoring module 152. The dynamic monitoring module 15 performs monitoring based on a positioning chip, an acceleration sensor, and a gyroscope sensor. The personnel dynamic monitoring module 151 is arranged at the backplate of the safety belt, and the hook dynamic monitoring module 152 is arranged in the intelligent safety belt hook body 133.

[0083] In this embodiment, as Figure 1 shown, the safety belt 11 serves as a carrier for the use of the safety belt system, providing protection for the operators. The personnel identification module 12 is used to identify and match the on-site operators. The intelligent safety belt hook 13 is used to monitor the usage of the safety belt 11. The height positioning module 14 is used for positioning the working height during the operation. The dynamic monitoring module 15 is used to monitor the usage status of the safety belt 11 and the operation status of the operators. This safety belt system can identify the working height, the usage status of the safety belt, and the movement status of the operators, and has a higher accuracy in judging the usage of the safety belt compared to the traditional single monitoring method, solving the problem of insufficient supervision of high-altitude operations in the existing video supervision technology. As a supplement to high-altitude operation video supervision, it enriches the supervision means, improves the supervision effect, and ensures the safety of high-altitude operations.

[0084] In this embodiment, as Figure 3 shown, the personnel identification module 12, the height positioning module 14, and the dynamic monitoring module 15 are encapsulated in the triangular area of the backplate of the safety belt 11, and the triangular area is covered with plastic parts to prevent bumps and ensure the stable operation of the system.

[0085] In this embodiment, as Figure 4 shown, the intelligent safety belt hook 13 further includes a force-bearing spring 134. The force-bearing moving unit 132 is connected to the pressure sensor 131 through the force-bearing spring 134 and is located at the bottom of the hook body 133 for sensing the hanging situation of the hook.

[0086] Specifically, the operator monitoring and warning system 2 includes a data processing module 21, an information communication module 22, a monitoring and warning module 23, and an enhanced positioning base station 24;

[0087] The data processing module 21 includes a data processor 211 and a data interface 212, which are arranged in the server;

[0088] The information communication module 22 is arranged at the backplate of the intelligent safety belt 1 and includes a data chip 221 and a signal integration unit 222. The data chip 221 is used to realize system communication, and the signal integration unit 222 is used to collect and process various types of information transmitted by the intelligent safety belt 1;

[0089] The monitoring and early warning module 23 is arranged at the back plate of the safety belt and includes an information warning unit 231 and an acoustic-optic vibration unit 232. The information warning unit 231 receives the information on the illegal use of the safety belt sent by the data processing module 21 and conducts remote monitoring and early warning, and the acoustic-optic vibration unit 232 is used to prompt the operator on site;

[0090] The enhanced positioning base station 24 is used to improve the positioning accuracy of the operator. The satellite positioning enhanced base station 241 is adopted outdoors, and the UWB positioning base station 242 is adopted indoors.

[0091] Specifically, the intelligent safety belt 1 adopts double hooks on both the left and right sides.

[0092] In this embodiment, as Figure 1 shown, according to the actual situation of the power site, the operator may be in an indoor working environment or an outdoor working environment. In different working scenarios, the safety belt system automatically identifies and selects satellite positioning 141 or UWB positioning 142. The satellite positioning 141 is applicable to the outdoor working environment, and the UWB positioning 142 is applicable to the indoor working environment. At the same time, an enhanced positioning base station 24 is set to ensure the accuracy of the operator's positioning height data, guarantee the safety of the operation process, and improve the safety of the high-altitude operation.

[0093] Embodiment 2

[0094] A method for discriminating the state of an operator by using the above safety belt system includes the following steps:

[0095] The height positioning module 14 in the intelligent safety belt 1 automatically selects the positioning data source according to the signal strength and determines the height information of the operator.

[0096] S01: Judge whether the operator is in a high-altitude operation state.

[0097] If the height of the safety belt in the positioning data is lower than 2m, it is judged that the operator is not in a high-altitude operation at this time, and the pressure sensor 131 and the dynamic monitoring module 15 on the intelligent safety belt hook 13 are not activated.

[0098] If the height of the safety belt in the positioning data exceeds 2m, it is judged that the operator is in a high-altitude operation state at this time, and the pressure sensor 131 and the dynamic monitoring module 15 on the intelligent safety belt hook 13 are in an activated state;

[0099] S02: Judge whether the operator is in a protected state in the high-altitude operation state.

[0100] If the height of the safety belt in the positioning data exceeds 2m and there is no pressure signal on the pressure sensor 131 on the intelligent safety belt hook 13, the operator loses protection at this time, and the data processing module 21 issues an alarm message.

[0101] S03: When in the protected operation state at high altitude, if the height of the safety belt for positioning data exceeds 2m and the pressure signal on the pressure sensor 131 is normal, the activated dynamic monitoring module 15 determines which specific operation state the operator is in.

[0102] If the personnel dynamic monitoring module 151 detects that the operator has an upward acceleration, and the hook dynamic monitoring module 152 detects that the double hooks alternately have an upward acceleration, and the height information of the positioning chip increases, then the operator is in the upward climbing state at this time.

[0103] If the personnel dynamic monitoring module 151 detects that the operator is horizontally stationary or has a horizontal acceleration, and the hook dynamic monitoring module 152 detects that the double hooks are in a stationary state, and the position information of the positioning chip does not change, then the operator is operating at a fixed position at this time.

[0104] If the personnel dynamic monitoring module 151 detects that the operator has a horizontal acceleration, and the hook dynamic monitoring module 152 detects that the double hooks alternately have a horizontal acceleration, and the positioning chip has a horizontal displacement change, then the operator is in the horizontal position transfer at this time.

[0105] If the personnel dynamic monitoring module 151 detects that the operator has a downward acceleration, and the hook dynamic monitoring module 152 detects that the double hooks alternately have a downward acceleration, and the height information of the positioning chip continuously decreases, then the operator is in the downward position movement state at this time.

[0106] If the personnel dynamic monitoring module 151 detects that the operator has a downward acceleration, and the hook dynamic monitoring module 152 detects that the double hooks simultaneously have a downward acceleration, and the height information of the positioning chip continuously decreases, then the operator is in the falling state at this time;

[0107] If the personnel dynamic monitoring module 151 detects that the operator has a short - term downward acceleration and then no downward acceleration, and the hook dynamic monitoring module 152 detects that the double hooks have no downward acceleration, and there is a pressure signal on the pressure sensor 131 on the intelligent safety belt hook 13 and the pressure exceeds 400N, then the personnel is in the falling and hanging state at this time;

[0108] S04: Judgment on whether the operator is in the state of using a safety belt with a lower hanging point and a higher attachment point.

[0109] If the height of the safety belt for positioning data exceeds 2m, and the hook dynamic monitoring module 152 detects that the positioning chips of the double hooks are lower than the backplate height, then there is a state of using a safety belt with a lower hanging point and a higher attachment point at this time, and an alarm message is sent.

[0110] In this embodiment, such as Figure 5As shown in the figure, the discrimination method of using this seat belt system combines the working height and the seat belt usage status to judge the working status of the operator. At the same time, according to the working status, it further judges whether the operator has lost protection and issues corresponding warning information, solving the problem of inaccurate identification of seat belt violations by a single means, accurately judging the status of the operator working at height and the seat belt usage status, solving the problem of insufficient supervision of working at height by the existing video supervision technology, serving as a supplement to the video supervision of working at height, enriching the supervision means, improving the supervision effect, and ensuring the safety of working at height.

[0111] In this embodiment, the discrimination method integrates the state judgment logic, reducing the monitoring false alarm rate. This discrimination method integrates multi-sensor signals and, through relevant logic algorithms, realizes accurate judgment of the status of the operator working at height, which can effectively reduce the false alarm situation caused by the lack of personnel status judgment and improve the accuracy of seat belt monitoring.

[0112] In this embodiment, the discrimination method mainly judges the status of the operator. On the one hand, it reduces the psychological burden of the operator working at height caused by false alarms, improves the safety of the operator working at height, and at the same time reduces the resistance of personnel to the use of monitoring equipment; on the other hand, it can judge the states such as the operator losing protection, the seat belt not being hung high and used low, the operator falling, and the operator hanging. Through relevant alarm signals, corresponding reminder and rescue measures can be carried out to ensure the safety of working at height and the emergency handling ability for emergencies.

[0113] Embodiment Three

[0114] Using the discrimination method for the status of the operator with the seat belt system described in the above Embodiment Two, the height positioning module 14 monitors the height information of the operator in real time, the personnel dynamic monitoring module 151 monitors the movement information of the operator, and the hook dynamic monitoring module 152 monitors the hook information of the intelligent seat belt 1, including the following discrimination results:

[0115] First, when the working height of the operator exceeds 2m and the operator is in a climbing state, a fixed-position working state, or a horizontal working position transfer state, and there is no pressure signal on both hooks, at this time the operator has lost protection and a warning message is issued;

[0116] Second, when the working height of the operator exceeds 2m and the operator is in a falling state, and the tensile force information on both hooks gradually increases, at this time the personnel have not lost protection and a warning message is issued;

[0117] Third, when the working height of the operator exceeds 2m and the operator is in a static state, and the tensile force of both hooks is the gravity of the operator, at this time the personnel are in a hanging state and the personnel have not lost protection and a warning message is issued;

[0118] Fourth, when the operating height of the operator exceeds 2m and the operator is in a falling state, the acceleration monitored by the acceleration sensor is greater than , when there is no tensile force information on the double hooks and the acceleration of the hooks is greater than , at this time, the operator is in a state of falling without protection, and an emergency warning message is issued.

[0119] In this embodiment, as Figure 6 shown, according to the discrimination method in Embodiment 2, combined with the pressure signals on the double hooks, the situation structure faced by the operator in different operating states is further judged, and different types of warning messages are issued. Especially when the operator is in a falling state and the safety belt does not play a protective role at this time, this is the most dangerous situation under the high-altitude operation conditions. The operator is facing life danger. In this case, an emergency warning signal is issued and measures are taken in time to ensure the safety of the operator to the greatest extent.

[0120] In summary, the safety belt system and discrimination method for monitoring the operating state of high-altitude operators overcome the deficiencies of the prior art. The safety belt system protects the operating safety of the operator according to the data on the intelligent safety belt 1 and in combination with the operator monitoring and warning system 2, and issues a warning message in time when protection is lost, ensuring the operating safety of high-altitude electric power operators. The discrimination method using this safety belt system can monitor the operating state of the operator in real time using this method logic.
