Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before explaining the embodiments of the present invention in detail, an application scenario and a system architecture related to the embodiments of the present invention are explained first.

First, an application scenario related to the embodiment of the present invention is described.

At present, more and more industries need to carry out high-altitude operation, an operator often gets high when carrying out operation tasks in an operation area, and if the operator does not wear a safety belt, the operator is likely to fall in the operation process, so that the life of the operator is threatened. However, the safety awareness of the existing operators is poor, and the operators often forget to wear safety belts, so that the falling accidents often happen.

Based on the scene, the embodiment of the invention provides the safety belt wearing detection method which can timely know the safety belt wearing condition of the operating personnel.

Next, a system architecture according to an embodiment of the present invention will be described.

Fig. 1 is a schematic diagram of an architecture of a seat belt wearing detection system provided in an embodiment of the present invention, and referring to fig. 1, the seat belt wearing detection system includes a camera 1, a monitoring platform 2, and a reader/writer 3. The camera 1 can be connected with the monitoring platform 2 and the reader-writer 3 in a wired or wireless manner to communicate with each other, and the monitoring platform 2 can be connected with the reader-writer 3 in a wired or wireless manner to communicate with each other.

The camera 1 is used for acquiring video information in a visible area, and determining the movement condition of an operator according to image information of the operator contained in the video information, or sending the acquired video information to the monitoring platform after acquiring the video information; the reader-writer is used for determining the position information of the operator according to the RFID label on the operator and/or determining the position information of the safety belt according to the RFID label on the safety belt; the monitoring platform 2 is used for determining the movement condition of the operator in the operation area according to the image information of the operator contained in the video information, and/or determining the movement condition of the operator in the operation area according to the position information of the operator, and/or determining the movement condition of the safety belt according to the position information of the safety belt, and then determining the safety belt wearing condition of the operator according to the movement condition of the operator and the movement condition of the safety belt in the operation area.

In addition, the system may include not only the camera 1, the monitoring platform 2, and the reader/writer 3, but also other devices, for example, a voice broadcasting device and a storage device. The voice broadcast device and the storage device can be respectively connected with the monitoring platform 2 in a wired or wireless mode to communicate, or the voice broadcast device and the storage device are respectively connected with the camera 1 in a wired or wireless mode to communicate. The voice broadcasting equipment is used for outputting a voice signal for reminding when an operator who does not wear a safety belt exists in the operator. The storage device is used for storing the video information acquired by the camera 1, so that the video information can be acquired from the storage device when the video information needs to be checked subsequently.

It should be noted that the camera 1, the monitoring platform 2, the reader/writer 3, the voice broadcast device, and the storage device may be mutually independent devices, and of course, at least one or more of the reader/writer 3, the voice broadcast device, and the storage device may be a component in the camera 1 and/or the monitoring platform 2.

After describing application scenarios and system architectures of the embodiment of the present invention, details of a seat belt wearing detection method provided by the embodiment of the present invention will be described with reference to the accompanying drawings.

Fig. 2 is a flow chart illustrating a seatbelt-wearing detection method according to an exemplary embodiment, referring to fig. 2, including the following steps.

Step 201: when the network equipment detects that an operator enters the working area, the movement condition of the operator in the working area is determined.

After the operator enters the operation area, the operator may move in the operation area, and the risk of falling of the operator is high in the moving process. Therefore, in order to avoid the occurrence of a falling risk, when the network device detects that the worker enters the work area, it is necessary to determine the movement of the worker in the work area.

It should be noted that the network device may be the camera shown in fig. 1, or may also be a monitoring platform.

Step 202: and the network equipment determines the movement condition of the safety belt according to the acquired position information of the safety belt in the working area.

Since the safety belt is worn by the operator, the safety belt worn by the operator is also moved during the movement of the operator. Therefore, in order to determine whether the worker wears the seat belt, the network device also needs to determine the movement of the seat belt based on the acquired position information of the seat belt in the work area.

Step 203: and the network equipment determines the safety belt wearing condition of the operator according to the coincidence degree of the movement condition of the operator and the movement condition of the safety belt.

When the worker moves while wearing the safety belt, the safety belt also moves, and when the worker moves without wearing the safety belt, the safety belt is in a stationary state. Therefore, the network device can determine the seat belt wearing condition of the operator based on the movement condition of the operator and the movement condition of the seat belt.

In the embodiment of the invention, when the network equipment detects that an operator enters the operation area, the movement condition of the operator can be determined, the movement condition of the safety belt is determined according to the acquired position information of the safety belt in the operation area, and then the safety belt wearing condition of the operator is determined according to the coincidence degree of the movement condition of the operator and the movement condition of the safety belt, so that the network equipment can clearly acquire whether the operator wears the safety belt, and can take measures according to the safety belt wearing condition of the operator in time subsequently, and the safety of the operation task of the operator in the operation area is improved.

Fig. 3 is a flow chart illustrating another seatbelt wear detection method, see fig. 3, according to an exemplary embodiment, including the following steps.

Step 301: when the network equipment detects that the operator enters the high-altitude operation area, the movement condition of the operator in the operation area is determined.

When a worker enters a working area, if a worker who does not wear a safety belt exists in the workers, the worker who does not wear the safety belt moves during working, and a falling risk is likely to occur in the moving process. Therefore, in order to detect whether the worker is likely to be in a fall risk, when the network device detects that the worker enters the work area, it is necessary to determine the movement of the worker within the work area.

The network device may determine the movement condition of the operator through video information acquired by the camera, and/or determine the movement condition of the operator through a Radio Frequency signal transmitted by a Radio Frequency Identification (RFID) tag carried by the operator, and two ways of determining the movement condition of the operator in the operation area by the network device are explained below.

In a first mode, the moving condition of the operator in the working area is determined by the network device according to the fact that the image information of the operator is contained in the video information collected by the camera, and the visible area of the camera covers part or all of the working area.

In general, in order to monitor the condition that an operator performs work in a work area, a camera for monitoring the work area is usually disposed in or near the work area, a visible area of the camera may cover a part or all of the work area, and the camera may collect video information of the visible area, where the video information may include image information of the operator located in the work area. Further, since the worker moves while performing work in the work area, the worker may move vertically when cleaning a building wall, for example. Therefore, the positions of the operators in the image information including the operators may be different. Therefore, the network equipment can determine the moving condition of the operator in the operation area by the image information of the operator contained in the video information collected by the camera.

It should be noted that, because the network device may be the operation area in fig. 1 or a camera near the operation area may also be the monitoring platform in fig. 1, when the network device is the operation area or the camera near the operation area, the network device directly determines the movement condition of the operator according to the image information of the operator included in the video information after acquiring the video information of the visible area. When the network equipment is a monitoring platform, the network equipment can send a starting request to a camera head in the operation area or near the operation area when detecting that an operator enters the operation area, so as to start the camera head to acquire video information of a visual area; after the video information is collected by the camera, the movement condition of the operator can be determined according to the image information of the operator contained in the video information, the video information can also be sent to the network equipment, and the movement condition of the operator is determined by the network equipment according to the image information of the operator contained in the video information collected by the camera.

The network equipment can determine the pixel point coordinates of a target characteristic point in the image information through an image recognition technology, wherein the target characteristic point is a characteristic point for describing the position of an operator; when the coordinates of pixel points of the target feature points in the image information change, determining that the operator moves; and when the coordinates of the pixel points of the target characteristic points in the image information are the same, determining that the operator does not move.

The movement of the operator means that a moving direction of the operator is consistent with a preset direction in a process of performing a task in the working area, and/or a position change of a moving distance not less than the preset distance. The predetermined direction is a normal direction for performing a task, such as a vertical down direction light. The preset distance may be set in advance, for example, the preset distance may be 0.3 meter, 0.5 meter, or the like.

It should be noted that when the network device is the camera arranged in or near the operation area, the camera is originally the electronic device in or near the operation area, so that when the technical scheme of the present invention is implemented, no other device needs to be arranged, the device expenditure is saved, and the safety belt wearing detection cost is reduced.

In the second mode, the movement of the operator in the work area is determined based on the position information of the operator in the work area, which is determined based on the radio frequency signal transmitted from the RFID tag provided on the operator.

When the network device detects that the operator enters the operation area, the RFID tag enters the read-write range of the reader-writer shown in fig. 1, and the reader-writer can read information carried in the RFID tag, such as signal strength, signal transmission direction and the like, and determine the position information of the RFID tag according to the read information, such as signal strength, signal transmission direction and the like. Because the reader-writer may be an independent device or a device in a network device (a camera or a monitoring platform), when the reader-writer is a device independent of the network device, the reader-writer may send the location information of the RFID tag to the network device, so that the network device may determine the movement condition of the operator according to the location information of the RFID tag. When the reader-writer is a device in the network device, the position information of the RFID tag of the reader-writer is equivalent to the position information of the RFID tag determined by the network device, and at this time, the network device can directly determine the movement condition of the operator according to the position information of the RFID tag.

In addition, the operation of determining the location information of the RFID tag by the reader based on the read information such as the signal strength and the signal transmission direction may refer to related technologies, which is not described in detail in the embodiments of the present invention.

When there is an operator whose position information has changed among the operators, it is determined that the operator whose position information has changed has moved, and when there is no operator whose position information has changed among the operators, it is determined that the operator has not moved.

It should be noted that, when the positioning is performed by the RFID tag, the position of the operator can be accurately positioned, so that the accuracy of determining the movement condition of the operator is improved.

Further, since the operator enters the work area only when the work area requires work, the operator is not present in the work area in a normal state, and therefore, in order to determine whether the operator is present in the work area, the network device needs to detect whether the operator enters the work area.

The operation of the network device for detecting that the operator enters the operation area may be: when a signal for judging that a pressure value sent by a pressure sensor arranged at a preset area is in a preset range is received, it is determined that an operator enters the operation area, and the preset area is located where the operator enters the operation area.

In addition, in the embodiment of the invention, the network device can detect whether the operator enters the operation area through the pressure sensor, and can also detect through other modes. For example, because a camera is arranged in or near the work area, the network device can collect video information through the camera at specified time intervals and perform person identification on the video information; when at least one person exists in the video information, determining that an operator enters the operation area; when no person is present in the video information, it is determined that the operator has not entered the work area.

It should be noted that the specified time interval may be set in advance, for example, the specified time interval may be 20 minutes, 30 minutes, 1 hour, and so on.

Optionally, under a normal condition, only when an operator exists in the working area, the condition that the operator is in the working area needs to be monitored, so that when the network device detects that the operator enters the working area through the pressure sensor, the camera is started and starts to acquire video information, otherwise, the camera is in a dormant state, and therefore resource waste is saved.

Step 302: and the network equipment determines the movement condition of the safety belt according to the acquired position information of the safety belt in the working area.

As can be seen from the above description, if the worker wears the safety belt, the worn safety belt will move along with the movement of the worker, and if the worker does not wear the safety belt, the safety belt will be in a stationary state during the movement of the worker, so in order to determine that the worker wears the safety belt, the network device may determine the movement of the safety belt according to the acquired position information of the safety belt in the working area. And the operation of the network device for determining the movement condition of the safety belt according to the acquired position information of the safety belt of the working area can be as follows: and determining the position information of the safety belt in the working area according to the wireless radio frequency signal transmitted by the RFID label arranged on the safety belt, and determining the moving condition of the safety belt in the working area according to the position information.

The RFID tag may be installed on the safety belt in advance, the network device determines the position information of the safety belt in the operation area according to the wireless radio frequency signal sent by the RFID tag installed on the safety belt, and the operation of determining the movement condition of the safety belt in the operation area according to the position information may refer to the operation of determining the movement condition of the operator in the operation area according to the RFID tag carried by the operator in step 301, which is not described in detail in the embodiments of the present invention.

When the network device determines the movement of the operator and the movement of the seat belt by using the RFID tag, the RFID tag carried by the operator is different from the tag identification of the RFID tag attached to the seat belt in order to distinguish the position information of the operator and the position information of the seat belt.

In addition, the network device can simultaneously acquire the position information of the operator and the position information of the safety belt through the reader-writer.

Step 303: and the network equipment determines the safety belt wearing condition of the operator according to the coincidence degree of the movement condition of the operator and the movement condition of the safety belt.

The safety belt is moved when the worker moves with the safety belt, and the safety belt is in a stationary state when the worker moves without wearing the safety belt. Therefore, the network device can determine the wearing condition of the safety belt of the operator according to the matching degree of the movement condition of the operator and the movement condition of the safety belt. The operation of the network device determining the seat belt wearing condition of the operator according to the matching degree of the movement condition of the operator and the movement condition of the seat belt may be: acquiring the number information of the operators, and when only one operator exists, if the operator moves and the safety belt does not move, or the difference value between the moving distance of the operator and the moving distance of the safety belt is larger than a preset distance range, determining that the operator does not wear the safety belt; when a plurality of operators exist, if the number of the operators moving is different from the number of the safety belts moving in the safety belts and/or the operators moving in the operators do not correspond to the safety belts moving in the safety belts, the operators not wearing the safety belts are determined to exist in the operators.

Since there may be one or more operators entering the work area, the network device needs to acquire information on the number of operators. Therefore, the network device can determine that the number of the operators in the preset pressure range is the number of the operators when receiving the signal that the pressure value sent by the pressure sensor arranged at the preset area is in the preset pressure range. For example, when the network device receives a signal that determines that the pressure value is within the preset range, it is indicated that only one operator enters the operation area, and therefore it is determined that the operator has only 1 person; when the network equipment receives 3 signals that the judgment pressure values are in the preset pressure range, 3 operators are determined. Alternatively, since a camera may be installed in the work area or the vicinity of the work area and the image information of the operator is included in the video information, the network device may identify the operator in the image information and determine the number of the operator according to the identification result.

In one possible implementation, when there is only one operator, if the operator moves and the safety belt does not move, it is determined that the operator does not wear the safety belt; if the worker moves and the safety belt moves, it is determined that the worker wears the safety belt. And/or, sometimes, when the operator moves without wearing the safety belt, the safety belt may be driven to slightly move due to some operations, and therefore, in order to accurately determine whether the operator wears the safety belt, the network device may determine that the operator does not wear the safety belt when a difference between a moving distance of the operator and a moving distance of the safety belt is greater than a preset distance range; and when the difference value between the moving distance of the operator and the moving distance of the safety belt is smaller than or equal to the preset distance range, determining that the operator wears the safety belt.

It should be noted that the preset moving distance may be set in advance, for example, the preset moving distance may be 1 meter, 0.5 meter, and the like.

As can be seen from the above, the network device can acquire the position information of the operator and the position information of the safety belt, and therefore, the network device can determine the moving distance of the operator according to the position information of the operator and determine the moving distance of the safety belt according to the position information of the safety belt.

In another possible implementation manner, when there are a plurality of operators, if the number of operators who move in the safety belts is different from the number of safety belts who move in the safety belts, that is, when the number of safety belts which move in the safety belts is smaller than the number of operators who move in the safety belts, it is determined that there is an operator who does not wear the safety belts among the operators; and if the number of the operators who move is the same as that of the safety belts and the operators who move correspond to the safety belts, determining that no operators who do not wear the safety belts exist in the operators. And/or, since some of the safety belts may be moved by the operation of the operator during the movement of the operator, but the moving direction, moving speed, moving distance, and the like of some of the safety belts may be different from the moving direction, moving speed, moving distance, and the like of the operator, when the operator moving among the operators does not correspond to the safety belt moving among the safety belts, it is determined that there is an operator who does not wear the safety belt among the operators.

Since the position information of the operator is similar to or identical to the position information of the seat belt when the operator moves while wearing the seat belt, the network device can determine whether the operator who moves corresponds to the seat belt that moves, from the position information of the operator and the position information of the seat belt.

The network equipment can determine whether the position information of the moving operator is similar or identical to the position information of the moving safety belt or not according to the position information of the operator determined in the image information including the operator, and/or the network equipment determines whether the position information of the moving operator is identical or similar to the position information of the moving safety belt or not according to the position information of the operator determined by the RFID tag, and when the position information of the moving operator is identical or similar to the position information of the moving safety belt, the moving operator is determined to correspond to the moving safety belt; and when the position information of the moving operator is far different from the position information of the moving safety belt, determining that the moving operator does not correspond to the moving safety belt.

The position information of the moving operator is similar to the position information of the moving seat belt, and the position information of the moving operator is represented by: the deviation between the position of the operator and the position of the safety belt is smaller than a preset position distance, the deviation between the moving direction of the operator and the moving direction of the safety belt is smaller than a preset angle, and the like.

For example, if the number of operators who move among the operators is 3 and the number of safety belts who move among the safety belts is 2, it is indicated that only 2 operators wear the safety belts and the remaining one does not wear the safety belts, and it can be determined that there are operators who do not wear the safety belts among the operators at this time; and/or, when the position information of 3 operators moving among the operators is that the moving directions of the operators are all vertical downward, and the 3 operators are respectively located at the position A, the position B and the position C, however, the position information of the 3 safety belts moving is as follows: the moving direction of the safety belt 1 is vertical downward and located at the position A, the moving direction of the safety belt 2 is vertical downward and located at the position B, and the position information of the safety belt 3 caused by the fact that the safety belt 3 is pulled vertically upward by other operators who do not move is as follows: the moving direction of the safety belt 3 is vertically upward and is located at the position D, which indicates that 3 operators moving among the operators do not correspond to 3 safety belts moving among the safety belts, and at this time, it is determined that there is an operator who does not wear a safety belt among the operators.

Step 304: and when the fact that the operator who does not wear the safety belt exists is determined, the network equipment carries out information reminding.

Because the worker who does not wear the safety belt is likely to have a risk of falling when the worker who does not wear the safety belt exists among the workers, in order to ensure the safety of the worker, when the worker who does not wear the safety belt is determined to exist among the workers, information reminding needs to be performed.

The network device is an electronic device such as a camera installed in or near a working area, and when the voice broadcasting device is a device in the network device, the stored reminding information can be directly played through the network device, and the reminding information is used for reminding operators who do not wear safety belts to exist in the operators. When the network equipment is a monitoring platform and plays the reminding information through electronic equipment such as a camera, independent voice broadcasting equipment and the like which are positioned in or near an operation area, the network equipment can acquire the sampling frequency of the electronic equipment; and coding and resampling the reminding information according to the sampling frequency of the electronic equipment, and sending the reminding information to the electronic equipment for playing.

It should be noted that, because different electronic devices have different encoding and decoding manners, some electronic devices may not be able to play the same reminder information, and therefore, the network device needs to perform encoding resampling on the reminder information again according to the sampling frequency of the electronic device.

When the network device plays the reminding information through the electronic device such as a camera or an independent voice broadcasting device located in or near the work area, the network device may determine the electronic device identifier corresponding to the work area from the corresponding relationship between the work area and the electronic device identifier, and then obtain the sampling frequency of the corresponding electronic device from the corresponding relationship between the electronic device identifier and the sampling frequency according to the electronic device identifier.

In addition, the electronic device identifier is used for uniquely identifying the electronic device located in or near the work area, and the electronic device identifier may be a factory serial number, a model number, or the like of the electronic identification.

It is worth mentioning that, the reminding information can be coded and resampled according to the sampling frequency of the electronic equipment located in the operation area or the operation area accessory, so that the reminding information can be played by any electronic equipment located in the operation area or the operation area accessory, and the reliability of information reminding is improved.

Furthermore, the safety belt in the work area may be brought into the work area when the worker enters the work area, or may be originally located in the work area. When the seat belt is originally located in the work area, the arrangement position of the seat belt may be fixed, and therefore, the seat belt may be numbered in advance. After the network device determines the movement condition of the safety belt according to the position information of the safety belt, if an operator who does not wear the safety belt exists in the operators, the network device may determine the number of the safety belt in the static state according to the number of the safety belt, and acquire the reminding information corresponding to the number of the safety belt in the static state. When the information reminding is carried out, reminding information corresponding to the number of the safety belt in the static state can be played to remind an operator to select the safety belt in the static state.

For example, when the numbers of 3 seat belts are respectively No. 1, No. 2, and No. 3, and an operator has 2 persons, if only one person wears seat belt No. 1, the network device may determine that one person does not wear the seat belt. When the network device determines that No. 2 safety belt and No. 3 safety belt are not worn by people, the network device can respectively acquire the reminding information corresponding to No. 2 safety belt and the reminding information corresponding to No. 3 safety belt, and alternately plays the reminding information "please wear No. 2 safety belt" corresponding to No. 2 safety belt and the reminding information "please wear No. 3 safety belt" corresponding to No. 3 safety belt.

It is worth noting that when the unified reminder is not wearing a harness, the operator may sometimes not be able to quickly determine which harness is not worn, finding an unworn harness may take some time, and the risk of falling is increased in the process of finding an unworn harness. When reminding the high-altitude operation personnel according to the serial number of the safety belt, the high-altitude operation personnel who do not wear the safety belt can quickly know which safety belt should be worn, and the safety belt is searched in a targeted mode, so that the time for searching the safety belt is shortened, and the safety of operation in an operation area is improved.

In addition, after the network device performs information reminding, the worker who does not wear the safety belt may wear the safety belt under the reminding of the reminding information, and the reminding may be stopped when the network device detects that all the workers wear the safety belt.

Further, the network device may also transmit information to stop the determination of the movement state of the operator when receiving the end information of the job task, and determine the reset state of the seat belt according to the acquired position information of the seat belt.

When the network device receives the end information of the job task, it indicates that the operator has left the job area, and at this time, it is not necessary to continuously detect that the operator wears the seat belt, and therefore, it is possible to transmit information for stopping the determination of the movement state of the operator. Meanwhile, when the safety belt in the operation area is the safety belt originally existing in the operation area, the network device can also determine the reset state of the safety belt according to the acquired position information of the safety belt in order to facilitate the next time of wearing the safety belt by the operator in the operation area. And when the unset safety belts exist in the safety belts, the safety belt reset reminding is carried out.

It should be noted that the network device may determine the reset state of the seat belt according to the manner of determining the moving state of the seat belt in step 302, that is, the network device may determine the position information of the seat belt in the operation area according to the radio frequency signal sent by the RFID tag disposed on the seat belt, and determine that the seat belt is reset after determining that the seat belt returns to the initial position according to the position information.

In addition, after the operation of the operator is finished, the operator will leave the operation area, at this time, the operator will pass through the preset area again, the pressure sensor will send the pressure value to the network device again, the network device may determine that the operator leaves the operation area when determining that the current number of times of the received pressure value is equal to the historical number of times, at this time, the network device may determine that the operator receives the end information of the operation task, and the historical number of times is the number of times of the pressure value received when determining that the operator enters the operation area.

Therefore, the safety belts in the operation area can be numbered in advance, and the network equipment can remind according to the safety belt numbers when the safety belts are worn to remind, so that the number of the safety belts which are not reset can be determined when the network equipment carries out safety belt reset reminding, reset reminding information corresponding to the number of the safety belts which are not reset is obtained, and the reset reminding information corresponding to the safety belts which are not reset is played in turn through the electronic equipment.

For example, when the numbers of 3 seat belts are respectively No. 1, No. 2, and No. 3, and when it is determined that No. 2 of the 3 seat belts is not reset, the network device may obtain the reset reminding information "please put the seat belt No. 2 back in place" corresponding to the seat belt No. 2, and play the reset reminding information through the electronic device.

It is worth mentioning that when the safety belt resetting reminding is carried out according to the serial number of the safety belt, an operator can quickly determine the safety belt which needs to be reset, and the safety belt resetting efficiency is improved.

In the embodiment of the invention, when the network equipment detects that an operator enters the operation area, the movement condition of the operator can be determined through the video information collected by the RFID or the camera carried by the operator, and the movement condition of the safety belt is determined through the RFD carried by the safety belt; and then, when the operator who does not wear the safety belt is determined to exist according to the movement condition of the operator and the movement condition of the safety belt, the network equipment can carry out information reminding, so that the falling danger caused by the fact that the operator does not wear the safety belt is avoided, and the safety of the operator in carrying out operation tasks is improved. Meanwhile, the network equipment can directly carry out information reminding through the camera in or near the operation area, so that the operation personnel in the operation area can hear the information reminding, and the reliability of the information reminding is improved.
