[0037] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the underground fusion networking private network operation system of the present application will be described in detail below in combination with specific embodiments.

[0040] In order to improve the security and reliability of data transmission, in an optional implementation manner, the above-mentioned transmission network networking also includes: an SPN networking subsystem, the above-mentioned SPN networking subsystem is a loop system formed by the communication connection between the newly added SPN equipment in the data room above the well and the transmission equipment underground, and the above-mentioned SPN networking subsystem includes the automatic switching function of the above-mentioned transmission equipment, and the above-mentioned automatic switching function is the function of automatically switching to the backup transmission link when the main transmission link fails; a signal coverage subsystem, the above-mentioned signal coverage subsystem is to utilize the transmission optical cable to meet the access of the above-mentioned wireless network networking and the above-mentioned transmission network networking; a transmission network protection subsystem, the above-mentioned transmission network protection subsystem is used to provide power supply protection for the above-mentioned transmission equipment.

[0041] Specifically, the SPN networking subsystem is constructed in C-RAN mode, that is, in a shared transmission mode. The SPN980 equipment is added to the well data room and the transmission equipment in the aggregation node of the transmission network to form a loop. The automatic switching function of the transmission equipment is used to ensure the safety of the equipment on the loop. The 5G SA private network base station directly reaches the aggregation room at the county level and above. The upper transmission network is constructed with a dual physical loop of no less than 50G to ensure that all sites in the private network are included in the loop. Each loop is connected to two transmission aggregation nodes in the uplink. The optical cable construction reasonably selects the route to avoid physical co-routing and co-cable looping, enhance site transmission protection, and double-link redundancy of the transmission route. The signal coverage subsystem reuses the old optical cable or builds the optical cable first to meet the access of the radio frequency remote unit and the baseband processing unit to the transmission network. The optical cable cores are 48 cores, 72 cores, and 96 cores. Transmission network protection subsystem, transmission equipment is protected by optical cable multi-routing solution.

When the city power is disconnected, the communication equipment immediately switches to battery power supply. The battery can ensure the normal operation of the equipment for 4 hours without interruption and meet the subsequent power supply needs.

[0042] In order to provide high-quality network services, in an optional implementation, the 5G base station within the above-mentioned wireless network is communicatively connected to the operator's core network.

[0043] Specifically, Figure 3 As shown, ordinary users and 5G applications can use network services through 5G base stations, respectively through two independent paths ( Figure 3 The operator core network includes a first operator core network and a second operator core network. The first operator core network is used to provide network services to individual users, and the second operator core network is used to provide network services to enterprise users. Figure 3The arrow-free connection line in the figure indicates that data communication can be carried out between the two. Through the dual uplink of the private network base station to the operator's ToC core network and To B core network, the access edge enhanced UPF for individual users and Internet users in the mining area is realized, providing high-quality network services for individual users and a stable network environment for corporate users.

[0045] Specifically, Figure 3 As shown, the core network networking includes adding a communication emergency guarantee board to the core network equipment that has been deployed in the existing network to form a UPF+ networking solution, which ensures that steady-state users do not lose connection and operate by inertia. After the large network is disconnected, users can re-access and ensure the smooth operation of the underground 5G private network. Due to the particularity of the physical location of the deployment, network boundaries, and bearer entities, UPF provides security protection for physical security, authentication and authorization, data transmission / boundary protection, etc. from multiple aspects such as the network layer and the business management layer.

[0047] Specifically, Figure 3 As shown, by adding a single board in the UPF cabinet in the mine area, UPF+ is implemented, including emergency AMF, emergency UDM and emergency SMF functions. The UPF+ networking solution does not need to add new network element nodes separately. The network element node is the smallest unit in network management, usually referring to the equipment in the network.

The status display module is used to display the equipment status of the above-mentioned monitoring equipment and the above-mentioned operating equipment, including whether the equipment is online, whether the operation is normal, whether there is a fault, etc. The data analysis module can use machine learning and artificial intelligence technology to realize intelligent analysis and prediction of data, such as predicting equipment failures and analyzing operating efficiency. The safety warning module can automatically detect abnormal conditions in the data according to preset safety thresholds or safety rules, and can also remind operators to pay attention to abnormal conditions of the equipment through sound and light alarms. Through the collaborative work of these modules, comprehensive monitoring and management of the underground working environment of coal mines is achieved.

[0052] In order to improve the accuracy of data anomaly detection, in an optional implementation, the data analysis module uses a deep learning algorithm to perform feature extraction analysis on the downhole data and uses a regular expression method to process and analyze the operator data.

[0053] Specifically, deep learning models such as convolutional neural networks (CNN) can be used for feature extraction of image data in underground data, and feature extraction and classification tasks can be completed simultaneously by training the model. Collect relevant text and other data obtained by users in the process of using Internet TV services. This data can cover all aspects of the service, such as content, interface, speed and other field information; the second step is to pre-process the collected text data to remove irrelevant characters, punctuation marks and other words that affect the judgment, that is, remove garbled characters, extra spaces, line breaks, tabs, etc., to avoid affecting the accuracy of the analysis; mainly use regular expressions (Regular Expression) for matching and replacement, by writing appropriate regular expressions and running them; for example, use the regular expression "\s+" to match one or more spaces and replace them with a space; use the regular expression "[^\w\s]" to match all non-alphanumeric and non-space characters, and replace them with an empty string to remove characters and punctuation marks that are not related to the data information. Then perform basic operations such as word segmentation and part-of-speech tagging on the text that excludes irrelevant information, and run the text through python. The specific code is as follows Figure 4 shown.

[0054] TGCN (temporal graph convolutional network) is used for convolution. TGCN can effectively process time series data and extract key features in the data through multiple convolution operations; that is, by combining graph convolutional networks and recurrent neural networks, the temporal information and spatial structure in the data can be effectively captured, and the original data can be converted into feature representation through convolution operations, that is, features are extracted through multiple convolutions to enhance the accuracy of data analysis.

[0056] Specifically, the image information acquisition module is equipped with high-speed cameras that can capture dynamic images underground and above the mine in real time. These high-speed cameras have high resolution and low-light performance to ensure clear images in various environments. The recording module is responsible for the operator data and the image information obtained by the above-mentioned monitoring equipment, and stores these data in the local or cloud database. The operator data includes the communication data of the mine employee users and the transmission network service data, network communication data and other data in the mine area. The image information includes the image timestamp, location data and the image itself. The upload module is responsible for uploading the image data and operator data through a secure network channel to the data analysis module of the intelligent real-time visualization subsystem for analysis. It has functions such as compression optimization and fault recovery mechanism. The fault recovery mechanism is to automatically re-upload the data that was not successfully sent after the network is interrupted. Through the collaborative work of these modules, the production efficiency of underground coal mine operations is improved.

[0057] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device.
