Description

Technical Field

[0001] The present invention relates to the technical field of ice makers, and more particularly, to a production safety monitoring system for ice makers. Background Art

[0002] In the daily operation and management of an ice maker production factory, safety in production is of utmost importance. To ensure the safety of the production process, it has become a common practice to monitor various production scenarios using cameras. By capturing the production site images with cameras, extracting the production features contained therein, and then deeply analyzing these features to check for potential safety hazards, and promptly alarming once a problem is found, the accident risk can be greatly reduced, the safety of personnel and equipment can be ensured, and the overall production efficiency can be improved.

[0003] However, the currently adopted technical solutions have significant drawbacks. Existing monitoring systems require manual configuration of rules or models for determining safety hazards for each camera that captures various production scenarios. However, the production layout of the factory is often dynamically adjusted, with the addition of new production equipment and the optimization of production processes being common occurrences. Whenever such changes occur, the corresponding cameras need to be reconfigured with the determination rules or models, which undoubtedly increases the management cost and time cost. Due to the intertwining of various factors, some cameras often fail to be timely configured with the determination rules or models for safety hazards, resulting in blind spots in the monitoring system and the inability to accurately identify potential safety hazards, posing a huge threat to safety in production. Summary of the Invention

[0004] In response to this, the present invention provides a production safety monitoring system for ice makers, an electronic device, a computer storage medium, and a computer program product to enhance the safety monitoring efficiency during the production of ice makers.

[0005] The present invention discloses a production safety monitoring system for an ice maker. The system includes a matching analysis module, a first safety risk analysis module, and a second safety risk analysis module. The matching analysis module is used to control a monitoring camera to capture a set of first video images of the production area of the ice maker, extract first production features from the first video images, and perform matching analysis on the first production features with a first safety risk determination module corresponding to the monitoring camera. Among them, the first production features include production equipment features, production material features, and production personnel operation features. The first safety risk analysis module is used to, if the matching analysis result is passed, control the monitoring camera to capture a set of second video images of the production area of the ice maker, extract second production features from the video images, use the first safety risk determination module to perform safety risk identification analysis on the second production features, and decide whether to output a first safety risk alarm signal. The second safety risk analysis module is used to, if the matching analysis result is not passed, feedback the first production features to the background server and receive a second safety risk determination module feedback by the background server, where the second safety risk determination module is matched by the background server according to the first production features. Use the second safety risk determination module to perform safety risk identification analysis on the second production features and decide whether to output a second safety risk alarm signal.

[0006] In some embodiments, the first safety risk determination module and / or the second safety risk determination module includes a safety risk determination strategy or a safety risk determination model.

[0007] In some embodiments, the second safety risk determination module is obtained by the following method: The background server performs matching analysis on the first production features with each safety risk determination module stored in the database. If there is a matching safety risk determination module, it is used as the second safety risk determination module and feedback to the corresponding monitoring camera. If there is no matching safety risk determination module, production accident cases of the same type of equipment are matched according to the production equipment features in the first production features in a specified production accident case library, semantic analysis of the accident causes of each production accident case is performed to obtain several training accident feature data. Among them, each production accident case at least includes an accident video and accident cause analysis information. A new safety risk determination module is constructed, and the new safety risk determination module is trained with each training accident feature data, and the trained new safety risk determination module is feedback to the corresponding monitoring camera.

[0008] In some embodiments, semantic analysis of the accident causes of each production accident case is performed to obtain a number of accident feature data for training, including: performing semantic analysis of the accident causes of each production accident case to obtain a number of accident feature data for training, and using each of the accident feature data for training as positive data; obtaining a number of normal production videos of the same type of equipment, obtaining a number of normal feature data for training based on each of the normal production videos, and using each of the normal feature data for training as negative data; constructing the positive data and the negative data into training data.

[0009] In some embodiments, the second safety risk analysis module is further configured to: after receiving the second safety risk determination module fed back by the background server, determine the remaining duration for clearing the first safety risk determination module according to the obtaining method of the second safety risk determination module; wherein, if the second safety risk determination module is obtained by training a new safety risk determination module, set the remaining duration to a first duration, otherwise set the remaining duration to a second duration; wherein, the first duration is greater than the second duration.

[0010] In some embodiments, the second safety risk analysis module is further configured to: after reaching the remaining duration, output a prompt message for clearing the first safety risk determination module to relevant personnel, and if a confirmation message for the prompt message fed back by relevant personnel is received, clear the first safety risk determination module from the corresponding monitoring camera; otherwise, do not clear the first safety risk determination module from the corresponding monitoring camera.

[0011] In some embodiments, clearing the first safety risk determination module from the corresponding monitoring camera includes: clearing the first safety risk determination module from the corresponding monitoring camera and feeding back the first safety risk determination module to the background server for storage.

[0019] The following specific embodiments illustrate the implementation manners of the present application. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0020] In addition, the technical features involved in different implementation manners of the present application described below can be combined with each other as long as they do not conflict with each other.

[0021] As Figure 1 shown, an embodiment of the present invention discloses an ice maker production safety monitoring system, and the system includes a matching analysis module, a first safety risk analysis module, and a second safety risk analysis module; the matching analysis module is used to control a monitoring camera to capture a set of first video images of the ice maker production area, extract first production features from the first video images, and perform matching analysis on the first production features with a first safety risk determination module correspondingly configured for the monitoring camera; wherein, the first production features include production equipment features, production material features, and production personnel operation features.

[0022] Among them, a plurality of key production areas in the ice maker production workshop are pre - laid out with surveillance cameras to obtain a set of first video images. The key production areas are, for example, raw material stacking areas, around core production equipment, personnel operation workstations, etc., to ensure full - coverage of all links of the production process. The frame rate of the captured first video images is stable and the picture is clear, so as to accurately capture the production dynamics.

[0023] Using image recognition technology and deep - learning algorithms, the collected first video images are analyzed to obtain production equipment features, production material features, and production personnel operation features respectively. Among them, the production equipment features include the model of the production equipment and its operating status (such as whether it is running normally, whether there are loose parts). The production material features include the type of material, stacking height, and quantity. The production personnel operation features include the standard degree of the monitoring personnel's limb movements and whether the operation actions conform to the preset standard process. Through feature extraction, structured first production feature data is formed.

[0024] The extracted first production features are matched with the first safety risk determination module pre - configured for the surveillance camera. This determination module stores a variety of preset standard production features and corresponding risk thresholds. When the matching degree between the actually extracted first production features and the standard production features reaches a certain proportion, it is determined that the matching is passed, that is, it is recognized that the first safety risk determination module stored in the surveillance camera is adapted to this production area and can be used to identify safety risk events in this production area; when the matching degree between the actually extracted first production features and the standard production features does not reach a certain proportion, it is determined that the matching fails, that is, it is recognized that the first safety risk determination module stored in the surveillance camera is not adapted to this production area and cannot be used to identify safety risk events in this production area. For example, the production function of this production area has been adjusted recently, other production equipment has been replaced or added, but the staff has not updated the corresponding safety risk determination module of this surveillance camera in time.

[0025] The first safety risk analysis module is used to, if the matching analysis result is passed, control the surveillance camera to capture a set of second video images of the ice maker production area, extract second production features from the video images, use the first safety risk determination module to conduct safety risk identification and analysis on the second production features, and decide whether to output a first safety risk alarm signal.

[0026] Among them, when the first security risk determination module stored in the monitoring camera is adapted to the production area, it indicates that the production function of the production area and the production equipment it contains have not changed. At this time, it can be determined that the first security risk determination module stored in the monitoring camera can still be used to identify security risk events in the production area. The monitoring camera continues to capture the second video image of the production area, and uses the first security risk determination module to perform risk analysis on the second production features extracted from the second video image. When the analyzed risk value exceeds the preset risk value, a first security risk alarm signal is output, that is, relevant personnel are reminded that there are security risks in the production area.

[0027] It should be noted that the feature content included in the first production features and the second production features is the same, that is, both include the above-mentioned production equipment features, production material features, and production personnel operation features.

[0028] The second security risk analysis module is used to, if the matching analysis result fails to pass, feedback the first production features to the background server and receive the second security risk determination module feedback by the background server, where the second security risk determination module is obtained by the background server according to the first production features; use the second security risk determination module to perform security risk identification analysis on the second production features and decide whether to output a second security risk alarm signal.

[0029] Among them, when the first security risk determination module stored in the monitoring camera is not adapted to the production area, it indicates that the production function of the production area and the production equipment it contains have changed, but the staff has not updated the corresponding security risk determination module of the monitoring camera in a timely manner. It is determined that the first security risk determination module stored in the monitoring camera is no longer applicable to identify security risk events in the production area. At this time, the monitoring camera sends the extracted first production features to the background server, and the background server obtains a second security risk determination module adapted according to the first production features. The monitoring camera performs security risk identification analysis on the second production features extracted above according to the received second security risk determination module and decides whether to output a second security risk alarm signal. This process is the same as the foregoing content and will not be elaborated here.

[0030] The above ice maker production safety monitoring system can independently analyze whether the built-in security risk determination module is adapted to the latest situation of the corresponding production area. If it is no longer adapted, it can obtain an adapted security risk determination module from the background server in a timely manner, so as to ensure that various potential safety hazards in the ice maker production process can be identified, comprehensively guarantee production safety, and reduce the accident rate.

[0031] In some embodiments, the first safety risk determination module and / or the second safety risk determination module includes a safety risk determination strategy or a safety risk determination model.

[0032] In the embodiments of the present invention, as Figure 2 shown, a set of safety risk determination strategies adapted to the corresponding production area can be packaged in the first safety risk determination module. The strategies include risk determination items for various safety risk types and their corresponding risk thresholds. When the risk value of any risk determination item exceeds the corresponding risk threshold, a safety risk alarm signal is output. Additionally, the first safety risk determination module can also be a corresponding safety risk determination model, which can be constructed by deep learning architectures such as convolutional neural network (CNN), long short-term memory network (LSTM), etc.

[0033] The process of the above safety risk determination module for safety risk analysis is roughly as follows: First, various types of equipment in the production of ice machines in the production area need to be identified, such as steel plate cutting equipment, stamping and shaping equipment, welding equipment, assembly equipment, etc. According to the above safety risk determination strategy or safety risk determination model, it is determined whether there are safety risks in the operating states of these equipment, such as whether there is waste material splashing, abnormal trajectory of the handling robotic arm, etc.

[0034] And the states of metal materials, plastic fittings, refrigerants, etc. used in the production of ice machines are identified, and according to the above safety risk determination strategy or safety risk determination model, it is determined whether there are safety risks in the states of these production materials. For example, whether there is a situation where the stacking height of production materials is too high, or materials that should not be mixed are mixed together.

[0035] At the same time, the operators are identified and the operation actions of the operators are extracted, and the standard degree of their operation actions is analyzed. For example, when assembling a key component, there are strict regulations on the order and torque size of tightening the screws, and an illegal operation is regarded as a risk event; there is also a limit on the operation duration in a dangerous area (such as near the electrical control cabinet), and staying overtime also triggers risk determination.

[0036] When the safety risk value corresponding to any of the above situations reaches the above risk threshold, a safety risk alarm signal can be output.

[0037] In some embodiments, the second security risk determination module is obtained through the following method: The background server performs matching analysis on the first production feature and each security risk determination module stored in the database. If there is a matching security risk determination module, it is used as the second security risk determination module and fed back to the corresponding monitoring camera; if there is no matching security risk determination module, production accident cases of similar equipment are obtained by matching the production equipment features in the first production feature in a specified production accident case library, and semantic analysis of the accident causes of each production accident case is performed to obtain a number of accident feature data for training; where each production accident case includes at least an accident video and accident cause analysis information; a new security risk determination module is constructed, and each training accident feature data is used to train the new security risk determination module, and the trained new security risk determination module is fed back to the corresponding monitoring camera.

[0038] In an embodiment of the present invention, when the background server receives the first production feature fed back by the monitoring camera, it is aware that the monitoring camera has the situation of "the production function of this production area has been adjusted recently, other production equipment has been replaced or added, but the staff has not updated the corresponding security risk determination module of this monitoring camera" and needs to configure a new security risk determination module for it.

[0039] At this time, the background server first performs matching analysis on the received first production feature and various preset standard production features in each security risk determination module stored in the database. If any standard production feature matches successfully, it is determined that the security risk determination module is suitable for analyzing the security risk type corresponding to the first production feature. At this time, the security risk determination module is used as the second security risk determination module and fed back to the corresponding monitoring camera. This security risk determination module may be the model in the monitoring camera originally located in other production areas in the ice-making machine production workshop. Correspondingly, all security risk determination modules suitable for each production area in this production workshop are stored in the database.

[0040] In addition, if all security risk determination modules in the database do not match the first production feature, the background server needs to construct a new security risk determination module and train it. Specifically, search for production accident cases of similar equipment in a specified production accident case library. Each production accident case includes at least an accident video and accident cause analysis information (written by the staff). By using a semantic analysis component to analyze the accident causes of each production accident case, a number of accident feature data for training can be obtained. These accident feature data for training include production equipment features, production material features, production personnel operation features before the accident, and corresponding accident labels (uniformly "there is an accident").

[0041] Use the above-mentioned accident feature data for training to train the new safety risk determination module, and send the trained new safety risk determination module to the monitoring camera. In this way, the monitoring camera can identify risks for new production functions and production equipment.

[0042] In some embodiments, semantic analysis of the accident causes of each of the production accident cases is performed to obtain a number of accident feature data for training, including: performing semantic analysis of the accident causes of each of the production accident cases to obtain a number of accident feature data for training, and using each of the accident feature data for training as positive data; obtaining a number of normal production videos of the same type of equipment, obtaining a number of normal feature data for training based on each of the normal production videos, and using each of the normal feature data for training as negative data; constructing the positive data and the negative data into training data.

[0043] In the embodiments of the present invention, to ensure the training effect of the new safety risk determination module, the training data used in the present invention includes positive data and negative data. The positive data is data of safety accidents, and the negative data is data of normal production without safety accidents.

[0044] Among them, the normal production videos of the same type of equipment can be obtained by crawling through network channels, or can be collected and fed back to the background server by the staff after a prompt is sent to the staff. The present invention does not make specific limitations on this.

[0045] In some embodiments, the second safety risk analysis module is further configured to: after receiving the second safety risk determination module fed back by the background server, determine the remaining duration for clearing the first safety risk determination module according to the obtaining method of the second safety risk determination module; wherein, if the second safety risk determination module is obtained by training the new safety risk determination module, set the remaining duration to the first duration, otherwise set the remaining duration to the second duration; wherein, the first duration is greater than the second duration.

[0046] In an embodiment of the present invention, after the monitoring camera obtains a new second security risk determination module, it is necessary to decide whether to clear the original first security risk determination module that is no longer applicable. In this regard, the present invention first analyzes the acquisition method of the second security risk determination module. If it is obtained by training a new security risk determination module, it indicates that the type of security risk corresponding to the first risk feature in this production area is not present in this production workshop. Since it is not clear whether the newly added production function is temporary or long-term, a longer waiting time is set before clearing the first security risk determination module to avoid accidentally deleting the first security risk determination module that may still be used in the future; otherwise, the second security risk determination module is a model in the monitoring camera of the original other production areas in the ice maker production workshop, indicating that the newly added production function in this production area is transferred from other production areas, and the probability of it being a long-term transfer is greater. At this time, a shorter waiting time is set before clearing the first security risk determination module.

[0047] In some embodiments, the second security risk analysis module is further configured to: after the remaining time is reached, output a prompt message for clearing the first security risk determination module to relevant personnel. If a confirmation message for the prompt message is received from the relevant personnel, the first security risk determination module is cleared from the corresponding monitoring camera; otherwise, the first security risk determination module is not cleared from the corresponding monitoring camera.

[0048] In an embodiment of the present invention, to avoid the clearing of the first security risk determination module not meeting the actual requirements of the ice maker production workshop, after the remaining time is reached, a clearing prompt can be given to relevant personnel. If they confirm, it indicates that the adjustment of the production function in the ice maker production workshop is long-term. At this time, the first security risk determination module stored in the monitoring camera and adapted to the old production function division can be cleared.

[0049] In some embodiments, clearing the first security risk determination module from the corresponding monitoring camera includes: clearing the first security risk determination module from the corresponding monitoring camera and feeding back the first security risk determination module to the background server for storage.

[0050] In an embodiment of the present invention, during the process of the first security risk determination module in the surveillance camera performing security risk analysis, it also performs periodic self-training based on the actually extracted production features. Therefore, the performance of the first security risk determination module for security risk analysis has been greatly improved. Therefore, in this embodiment of the present invention, it is not directly deleted from the surveillance camera, but is transmitted back to the background server, and the background server makes a decision on its subsequent use. For example, the background server transmits the first security risk determination module to the surveillance camera of the corresponding production area after the production function is adjusted.
