Description

Technical Field

[0001] The present invention relates to the technical field of safety protection for climbing operations, and in particular to a safety protection device and system for climbing operations. Background Art

[0002] In the field of rail transit, three-story work platforms are required in locomotive depot preparation yards, EMU depot (station) maintenance depots, vehicle depot maintenance depots, passenger vehicle depot maintenance depots, and subway vehicle depot maintenance depots to meet the requirements of rooftop operations. To ensure the safety of maintenance personnel working on the rooftop and prevent electric shock accidents, a safety door is required on the top platform. The safety door can only be opened with authorization when the contact network is de-energized and the ground wire is connected. Therefore, before the contact network is energized, it is necessary to accurately determine whether there are people stranded on the roof, which is a very critical safety protection work.

[0003] Existing security gates generally restrict entry and exit or detect the number of people through card swiping, video image analysis, photoelectric sensors and infrared detection; using card swiping to restrict entry and exit or detect the number of people, because there is a possibility that one person swipes the card and multiple people enter and exit, it is impossible to ensure accurate detection of the number of people who reach the summit; using video counting to identify the number of people passing through, the existing image processing algorithm has certain defects and is not mature enough. When someone wears loose clothes or a hat or mask, it may not be accurately identified; using photoelectric sensors to sense the number of people passing through, it cannot accurately detect, and when someone passes shoulder to shoulder or with their back to someone, it may not be accurately identified; using infrared detection to identify the number of people passing through, it also cannot accurately detect, and when people in the detection area wear hats or other objects blocking the lens, it may also not be accurately identified.

[0004] Therefore, in the prior art, the safety door and the anti-tailgating system cannot reliably and accurately detect whether there is a person left on the roof, or the detection effect is unsatisfactory. Summary of the Invention

[0005] In response to the technical problems in the above-mentioned safety protection technology for climbing operations, the existing safety doors and anti-tailgating systems cannot reliably and accurately detect whether there are people left on the roof, or the detection effect is unsatisfactory. The present invention provides a safety protection device and system for climbing operations. The safety protection device and system provided by this solution can effectively determine the situation of people stranded on the operating platform, improve the efficiency of operations such as power cutting and power transmission, and ensure the safety of operators.

[0006] The present invention provides a climbing operation safety protection device and system to solve the problem through the following technical points: a climbing operation safety protection device includes a ladder and a work platform arranged above the ladder, and also includes a weighing car arranged between the ladder and the work platform, the weighing car is used to provide a communication channel connecting the ladder and the work platform;

[0007] A second door body is provided between the weighing car and the ladder for controlling the communication state between the weighing car and the ladder;

[0008] A first door body for controlling the communication state between the weighing car and the working platform is provided between the weighing car and the working platform.

[0009] When this solution is used in practice, the ladder is used as a climbing ladder, such as a climbing escalator, and the working platform provides a working space. If a supporting platform with a fence is used, the weighing car is set between the ladder and the working platform to achieve communication between the ladder and the working platform. At the same time, when people pass through the weighing car, the weight of the workers is collected.

[0010] When this solution is put into practical use, when the operator enters the working platform, they first need to pass through a weighing car. Therefore, during the entry process, the weight of each operator can be collected, and the collected weight value can be used as the operator's top mark data, such as defined as a pre-stored weight value. When the operator returns to the ground from the working platform after completing the operation, they first need to pass through a weighing car. Therefore, during the process of going down, the weight of each operator can be collected again, as the operator's top mark data, such as defined as the current weight value. By comparing the pre-stored weight value and the current weight value, if the multiple current weight values obtained all coincide with the multiple pre-stored weight values obtained previously, it can be determined that all the personnel who performed the climbing operation have returned to the ground from the working platform. At this time, it can be determined that power can be supplied safely.

[0011] The technical solution provided above allows for efficient and accurate determination of personnel retention on the platform, as data can be collected during the operator's entry and exit. This avoids the existing issue of multiple card usage and the potential for missed identifications due to inadequate signal collection and the resulting difficulty in achieving comprehensive detection and control. This solution effectively improves the efficiency of power-off and power-off operations and ensures the safety of personnel.

[0012] In the above scheme, it is set to also include a first door body and a second door body, with the weighing car as a reference, and the first door body and the second door body are intended to realize operator access and exit control. For example, during the operator's climbing operation, through the corresponding face recognition device, fingerprint recognition device and other on-site identification devices, through remote control, the second door body is used to realize selective access of personnel entering the weighing car, and the first door body is used to realize the exit of the weighing car when the weighing car collects a valid weight value. During the operator's return to the ground, the first door body is used to realize selective access of personnel entering the weighing car, and the second door body is used to realize the exit of the weighing car when the weighing car collects a valid weight value. In this way, it is convenient to realize the effective collection of weight values in the weighing car both during the operator's climbing operation and during the return to the ground, and to realize selective access and exit at the same time.

[0013] Further technical solutions are:

[0014] As a specific technical solution for achieving selective entry and exit, in conjunction with the above-mentioned arrangement of the first and second doors, a first facial recognition device for identifying people on the ladder and a second facial recognition device for identifying people on the work platform are provided. This solution utilizes facial recognition devices to achieve entry and exit determination. This solution is not only a contactless determination method, but also has the characteristics of high determination efficiency. Furthermore, images captured during facial recognition can be used, such as by a control center or dispatch center, to remotely determine whether entry and exit are achieved based on the structure of the first and second doors. In specific operation, the system can also include a control system used with the device, wherein a storage module and a control module are provided in the control system. For example, the storage module pre-stores authorized personnel information, and the pre-stored personnel information is compared with the personnel information collected by the facial recognition device to determine whether the corresponding personnel are allowed to enter or exit the weighing car. The above-mentioned personnel access solution based on the control center or dispatch center can be achieved by establishing communication between the facial recognition device and the control center or dispatch center, and establishing remote control of the first and second doors by the control center or dispatch center.

[0015] To achieve more accurate local identification or identity verification based on different modes, the first and second facial recognition devices are each paired with a fingerprint recognition device. This solution can combine facial recognition with fingerprint recognition to achieve more accurate identity verification. This solution can determine whether to use facial or fingerprint identification based on previously entered information. In practical applications, existing integrated fingerprint and facial recognition devices can be used.

[0016] As a technical solution that is safe to use and has a simple structure, it is set as follows: the working platform and the weighing car form a strip structure, the weighing car is set at one end of the working platform, the first door body is a swing door, and the second door body is a sliding door. In this solution, if a strip-shaped platform board is set at the upper end of the ladder, and a fence is set at the edge of the platform board to form a basket including the space for setting up the working platform and the weighing car, and then the first door body is set in the basket, a separate working platform and weighing car space can be obtained. After setting a car floor in the weighing car space and setting a weighing sensor between the car floor and the platform board, the weighing car main structure is obtained. At the same time, a second door body is set on the fence that constrains the boundary of the weighing car, and the on-off control of the ladder and the weighing car is realized through the second door body, the solution can be obtained. Adopting the above solution at the same time makes it easy to obtain a strip-shaped working operation space. The above selection of the first door body and the second door body is intended to consider the space problem required for the use of the first door body, and the selection of the second door body is intended to consider the safety problem of the use of the second door body.

[0017] More completely, in order to facilitate the control of the opening and closing states of the first door body and the second door body, so that confirmed or authorized personnel can pass through the weighing car, it is configured that: the first door body and the second door body are both equipped with a driving mechanism for driving their respective opening and closing states or a locking mechanism for actively locking their respective closed states. When this solution is used in practice, if the driving mechanism is adopted, the corresponding door body is opened by the driving mechanism after the personnel access is confirmed or authorized; if the locking mechanism is adopted, the locking mechanism changes the locking state of the corresponding door body after the personnel access is confirmed or authorized, so that the corresponding personnel can open the corresponding door body by manual operation.

[0018] As a specific implementation method of the weighing car, it is set as follows: the weighing car includes a car body and a weighing sensor arranged below the car body.

[0019] In order to facilitate the personnel in the weighing car to directly obtain the weighing structure, such as through the timely output of weight collection data, to determine the fault situation of the weighing car, so as to avoid affecting the subsequent timely return to the ground; considering the spare parts and tools carried by the operating personnel, through the previous weight collection data output, the operating personnel are reminded that they need to match the corresponding replaced parts or tools when returning to the ground, it is set to: also include a weight value output device for outputting the weighing result of the weighing car, and the weight value output device is used to provide the weighing result to the personnel in the weighing car. The weight value output device preferably adopts a voice playback device, and is also set to include a weighing start prompt broadcast function to remind the personnel in the weighing car to maintain a reasonable standing posture to obtain more accurate collection results.

[0020] More completely, the present solution also discloses a climbing operation safety protection system, comprising the safety protection device as described above, and an electric control cabinet, wherein a control module and a storage module are provided in the electric control cabinet, wherein the storage module is used to store the collected weighing car weight value; the control module is used to control the opening and closing of the second door body: by calling the weight value previously stored in the storage module, and comparing the called weight value with the current weighing car weight value, whether the second door body is opened is controlled.

[0021] As a further technical solution of the safety protection system:

[0022] As a technical solution that allows a control center or a dispatching center to remotely control whether the above device allows corresponding personnel to enter or exit as needed, it is configured as follows: a communication module is also provided in the electric control cabinet, the communication module is connected to the control module signal, the communication module receives the remote control instruction, and inputs the control instruction into the control module to control whether the second door body is opened through the control instruction. More preferably, it is configured so that the above communication module is connected to the storage module signal so that the corresponding access information is remotely input into the storage module through the communication module, so that the above protection device can replace or update the operator information who is allowed to use the above protection device very conveniently based on a single use. The specific access information can be set to include any one or more of weight information, facial information, and fingerprint information according to the needs of use. For the above weight information, it is preferred to use a range value to match the operator's clothing, weight fluctuations, spare parts, and tool carrying conditions, etc.

[0023] A more complete technical solution, as a combination of personnel information determination and entry and exit control, is provided as follows: the safety protection device further includes a first face recognition device for identifying people on the ladder and a second face recognition device for identifying people on the work platform;

[0024] The first face recognition device is used to realize the access confirmation of the personnel in the weighing car. After the confirmation is successful, the second door body is opened by the control module. After the personnel enter the weighing car, the weighing car completes the weight value collection and obtains the pre-stored weight value;

[0025] The second face recognition device is used to confirm the access of personnel to the weighing car. After successful confirmation, the first door body is opened through the control module. After the personnel enter the weighing car, the weighing car completes the weight value collection and obtains the current weight value;

[0026] The control module compares the preset weight value with the current weight value, and determines whether the second door is opened according to the comparison result.

[0027] The present invention has the following beneficial effects:

[0028] The safety protection device and system provided by this solution not only achieves high efficiency and accuracy, as the data used to determine whether workers are stranded on the work platform can be collected while they are entering and exiting the work platform. This avoids the problem of using multiple cards for a single purpose, as seen in existing technologies, and also avoids issues such as missed identifications caused by inadequate signal collection and difficulty in achieving comprehensive detection and control. This solution effectively improves the efficiency of operations such as power interruption and power supply, and effectively ensures the safety of workers.

[0029] In the above scheme, it is set to also include a first door body and a second door body, with the weighing car as a reference, and the first door body and the second door body are intended to realize operator access and exit control. For example, during the operator's climbing operation, through the corresponding face recognition device, fingerprint recognition device and other on-site identification devices, through remote control, the second door body is used to realize selective access of personnel entering the weighing car, and the first door body is used to realize the exit of the weighing car when the weighing car collects a valid weight value. During the operator's return to the ground, the first door body is used to realize selective access of personnel entering the weighing car, and the second door body is used to realize the exit of the weighing car when the weighing car collects a valid weight value. In this way, it is convenient to realize the effective collection of weight values in the weighing car both during the operator's climbing operation and during the return to the ground, and to realize selective access and exit at the same time.

[0030] The above-mentioned weighing car is used as the channel basis for the upper and lower working platforms, so this solution can also be used to realize abnormal weight identification prompts for dispatching. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present invention will be further described in detail below with reference to the embodiments, but the structure of the present invention is not limited to the following embodiments.

[0035] Example 1:

[0036] like Figure 1 and Figure 2 As shown, a climbing operation safety protection device includes a ladder 1 and a work platform 2 arranged above the ladder 1, and also includes a weighing car 4 arranged between the ladder 1 and the work platform 2, the weighing car 4 is used to provide a communication channel connecting the ladder 1 and the work platform 2;

[0037] A second door 6 is provided between the weighing car 4 and the ladder 1 for controlling the communication state between the weighing car 4 and the ladder 1;

[0038] A first door 5 for controlling the communication state between the weighing car 4 and the working platform 2 is provided between the weighing car 4 and the working platform 2 .

[0039] When this solution is used in practice, the ladder 1 is used as a climbing ladder, such as a climbing escalator, and the working platform 2 provides a working space. If a supporting platform with a fence is used, the weighing car 4 is set between the ladder 1 and the working platform 2 to achieve communication between the ladder 1 and the working platform 2. At the same time, when a person passes through the weighing car 4, the weight of the person is collected.

[0040] When this solution is put into practical use, when the operator enters the working platform 2, since they first need to pass through the weighing car 4, the weight of each operator can be collected during the entry process, and the collected weight value can be used as the operator's top mark data, such as defined as a pre-stored weight value. When the operator returns to the ground from the working platform 2 after completing the operation, since they first need to pass through the weighing car 4, the weight of each operator can be collected again during the grounding process, as the operator's top mark data, such as defined as the current weight value. By comparing the pre-stored weight value and the current weight value, if the multiple current weight values obtained are respectively coincident with the multiple pre-stored weight values obtained previously, it can be determined that all the personnel performing the top operation have returned to the ground from the working platform 2. At this time, it can be determined that power can be supplied safely.

[0041] The above-described technical solution allows for efficient and accurate determination of worker retention on work platform 2, as data can be collected while workers are entering and exiting the platform. This avoids the existing issue of multiple card usage and the potential for missed identifications due to inadequate signal collection and the resulting difficulty in achieving comprehensive detection and control. This solution effectively improves the efficiency of power-off and power-off operations and ensures worker safety.

[0042] In the above scheme, it is set to also include a first door body 5 and a second door body 6. Taking the weighing car 4 as a reference, the first door body 5 and the second door body 6 are intended to realize operator access and exit control. For example, during the operator's ascent to the top, through the corresponding face recognition device, fingerprint recognition device, or other on-site identification device, through remote control, the second door body 6 is used to realize selective access to the weighing car 4, and the first door body 5 is used to realize, if the weighing car 4 collects a valid weight value, the weighing car 4 is allowed to exit. During the operator's return to the ground, the first door body 5 is used to realize selective access to the weighing car 4, and the second door body 6 is used to realize, if the weighing car 4 collects a valid weight value, the weighing car 4 is allowed to exit. In this way, it is convenient to realize the effective collection of weight values of the weighing car 4 both during the operator's ascent to the top and during the return to the ground, and to realize selective access and exit.

[0043] At the same time, this embodiment also discloses a climbing operation safety protection system, including the safety protection device as described above, and also including an electrical control cabinet 8, wherein a control module and a storage module are provided in the electrical control cabinet 8, and the storage module is used to store the collected weight value of the weighing car 4; the control module is used for the opening and closing control of the second door body 6: by calling the weight value previously stored in the storage module, and comparing the called weight value with the current weight value of the weighing car 4, whether the second door body 6 is opened is controlled.

[0044] Example 2:

[0045] like Figure 1 and Figure 2As shown, this embodiment is further defined on the basis of Example 1: as a specific technical solution for achieving selective entry and exit matching the above-mentioned first door body 5 and second door body 6, it is configured to further include a first facial recognition device 3 for identifying people on the ladder 1 and a second facial recognition device 7 for identifying people on the work platform 2. This solution uses the facial recognition device to achieve entry and exit determination. This solution is not only a non-contact determination method, but also has the characteristics of high determination efficiency. At the same time, the image collected during the facial recognition process can be used, such as by a control center or a dispatch center, to remotely determine whether to achieve entry and exit based on the structure of the first door body 5 and the second door body 6. In specific operation, it can be configured to also include a control system used with this device, and the control system is provided with a storage module and a control module. For example, the storage module pre-stores authorized personnel information, and the pre-stored personnel information is compared with the personnel information collected by the above-mentioned facial recognition device to determine whether the corresponding person is allowed to enter or exit the weighing car 4. For the above personnel access scheme based on the control center or dispatch center, it can be completed by establishing communication between the face recognition device and the control center or dispatch center, and at the same time establishing remote control of the first door body 5 and the second door body 6 by the control center or dispatch center.

[0046] To achieve more accurate local identification or identity verification based on different modes, the first facial recognition device 3 and the second facial recognition device 7 are both equipped with fingerprint recognition devices. This solution can combine facial recognition with fingerprint recognition to achieve more accurate identity verification. This solution can also determine whether to use facial or fingerprint identification based on previously entered information. In practical applications, existing fingerprint and facial recognition all-in-one devices can be used.

[0047] As a technical solution that is safe to use and has a simple structure, it is set as follows: the working platform 2 and the weighing car 4 form a strip structure, the weighing car 4 is set at one end of the working platform 2, the first door body 5 is a swing door, and the second door body 6 is a sliding door. In this solution, if a strip-shaped platform board is set at the upper end of the ladder 1, and a fence is set at the edge of the platform board to form a basket including the space for the working platform 2 and the weighing car 4, and then the first door body 5 is set in the basket, a separate space for the working platform 2 and the weighing car 4 can be obtained. After the space for the weighing car 4 is set as a car floor and a weighing sensor is set between the car floor and the platform board, the main structure of the weighing car 4 is obtained. At the same time, a second door body 6 is set on the fence that constrains the boundary of the weighing car 4, and the on-off control of the ladder 1 and the weighing car 4 is achieved through the second door body 6, the solution can be obtained. Adopting the above solution at the same time makes it easy to obtain a strip-shaped working operation space. The above selection of the first door body 5 and the second door body 6 is intended to consider the space problem required for the use of the first door body 5, and the selection of the second door body 6 is intended to consider the safety problem of the use of the second door body 6.

[0048] More completely, in order to facilitate the control of the opening and closing states of the first door body 5 and the second door body 6 so that confirmed or authorized personnel can pass through the weighing car 4, it is configured as follows: the first door body 5 and the second door body 6 are both equipped with a driving mechanism for driving their respective opening and closing states or a locking mechanism for actively locking their respective closed door states. When this solution is used in practice, if the driving mechanism is adopted, the corresponding door body is opened by the driving mechanism after the personnel access is confirmed or authorized; if the locking mechanism is adopted, the locking mechanism changes the locking state of the corresponding door body after the personnel access is confirmed or authorized, so that the corresponding personnel can open the corresponding door body by manual operation.

[0049] As a specific implementation of the weighing car 4, it is set as follows: the weighing car 4 includes a car body and a weighing sensor arranged below the car body.

[0050] To facilitate the personnel in the weighing car 4 to directly obtain the weighing structure, such as through the timely output of weight collection data, to determine the fault of the weighing car 4, so as to avoid affecting the subsequent timely return to the ground; considering the spare parts and tools carried by the operating personnel, through the previous weight collection data output, the operating personnel are reminded that they need to match the corresponding replaced parts or tools when returning to the ground, it is set to: also include a weight value output device for outputting the weighing result of the weighing car 4, and the weight value output device is used to provide the weighing result to the personnel in the weighing car 4. The weight value output device preferably adopts a voice playback device, and is also set to include a weighing start prompt broadcast function to remind the personnel in the weighing car 4 to maintain a reasonable standing posture to obtain more accurate collection results.

[0051] Example 3:

The communication module receives the remote control instruction and inputs the control instruction into the control module to control whether the second door body 6 is opened by the control instruction. More preferably, it is set to be connected to the storage module signal so that the corresponding access information can be remotely input into the storage module through the communication module, so that the above protection device can replace or update the operator information who is allowed to use the above protection device very conveniently according to a single use. The specific access information can be set to include any one or more of weight information, facial information, and fingerprint information according to the needs of use. For the above weight information, it is preferred to use a range value to match the operator's clothing, weight fluctuations, spare parts, and tool carrying conditions, etc.

[0053] A more complete technical solution for realizing access and exit control by combining personnel information determination is as follows: the safety protection device further includes a first face recognition device 3 for identifying a person on the ladder 1 and a second face recognition device 7 for identifying a person in the working platform 2;

[0054] The first face recognition device 3 is used to realize the access confirmation of the personnel in the weighing car 4. After the confirmation is successful, the second door 6 is opened by the control module. After the personnel enters the weighing car 4, the weighing car 4 completes the weight value collection and obtains the pre-stored weight value;

[0055] The second face recognition device 7 is used to realize the access confirmation of the personnel in the weighing car 4. After the confirmation is successful, the first door 5 is opened by the control module; after the personnel enter the weighing car 4, the weighing car 4 completes the weight value collection and obtains the current weight value;

[0056] The control module compares the preset weight value with the current weight value, and determines whether the second door 6 is open based on the comparison result.

[0057] Example 4:

[0058] Based on the above embodiments, this embodiment provides a more detailed and specific implementation scheme: This safety protection system consists of a climbing ladder as a ladder 1, a working platform 2 including a guardrail, a climbing face recognition device including a first face recognition device 3, a weighing car 4, a push door as a first door body 5, an electric sliding door as a second door body 6, a lower face recognition device including a second face recognition device 7, and an electric control cabinet 8. At the same time, this system is a safety card control system that collects and identifies the passage of operating personnel.

[0059] The climbing escalator is assembled from inclined climbing steps, guardrails on both sides of the steps, and a top platform and other components, and is installed in the installation opening reserved on the top working platform 2 by bolt connection.

[0060] The guardrail is assembled from a frame connected on all sides and a protective net arranged on the frame, and is installed on the top platform of the climbing escalator through bolt connection.

[0061] The summit face recognition device consists of a face recognizer, a bracket for installing the recognizer, and an access control installed on the sliding door, and is installed on the guardrail and the sliding door through bolt connections.

[0062] The weighing car 4 is composed of a car carrying workers and a weighing sensor, a camera, a broadcaster, etc. arranged at the bottom of the car, and is installed on the top platform of the climbing escalator through bolt connections.

[0063] The sliding door is composed of a transparent door panel and hinges and a closer arranged on the door panel, and is installed on a guardrail or a car through bolt connection.

[0064] The electric sliding door is composed of a transparent door panel and an electric sliding mechanism, a pulley, a detection sensor, etc. arranged on the door panel, and is installed on the guardrail by being embedded.

[0065] The lower top face recognition device consists of a face recognizer and a bracket for installing the recognizer, as well as an electric switch installed on the sliding door, and is installed on the guardrail and the sliding door through bolt connections.

[0066] The electric control cabinet 8 is composed of an access controller, an analog junction box, etc., and is arranged in the control cabinet of the safety interlock monitoring system to control the safety door of the corresponding track.

[0067] The climbing process of this scheme is that the operating personnel complete the climbing inventory through the information system associated with the safety interlock monitoring system, and enter the weighing cabin 4 by the climbing escalator: face recognition is performed through the climbing face recognition device. After identification of authorization, the electric sliding door access control automatically opens, and the operating personnel enter the weighing cabin 4 through the electric sliding door, and the electric sliding door automatically closes and locks. At the same time, considering the effectiveness of weighing, it is set that if the electric sliding door is not locked, weighing will not be performed, and then a voice prompt will be given to start weighing, weighing data, etc. After weighing is successful, the door will be automatically opened, and the operating personnel will enter the top platform serving as the working platform 2, and then the door will be automatically locked.

[0068] The lowering process of this scheme is that the operator uses the lowering face recognition device to perform face recognition. If the recognition is successful, the push door will automatically open, and the operator enters the weighing cabin 4, and the push door will automatically close. Similarly, if the push door is not closed, no weighing will be performed. Then, the voice prompt will start weighing, weighing results, etc. After the weighing match is successful, the electric sliding door access control will automatically open, the operator will open the electric sliding door, and the lowering is completed.

[0069] More specifically, for the climbing process, the principle of this solution is that the electric control cabinet 8 receives the climbing operation information through the safety interlock monitoring system and transmits it to the face recognition system. The system automatically identifies the personnel information and converts the identification signal into an access control opening signal. The operator enters the weighing cabin 4 through the electric sliding door, collects the gravity signal through the weighing sensor, and the access control executes the locking signal. After the electric sliding door is locked, the gravity sensor starts to collect weight and converts the process signal into a voice signal during the collection process. It is preferably set as follows: if the operator keeps moving during the collection process, a voice prompt will be triggered. If the collection is successful, the weight will be converted into a voice broadcast and the door-pushing control device will be triggered. The control signal is switched to a door-pushing opening signal. The operator enters the top platform and completes the climb. This system transmits the weight binding information back to the control center or dispatching center through the electric control cabinet 8.
