Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 and Figure 2This utility model provides an embodiment of a transformer substation convergence terminal, comprising a housing 1. The housing 1 internally houses a power management module, a main control module, a remote signaling module, a security module, a clock module, an AC sampling module, a positioning and substation identification module, a fault detection and judgment module, a local maintenance interface module, an event recording and storage module, a status monitoring module, a communication module, an early warning and reminder module, and a status indication module.

The power management module includes a main power supply and a backup power supply, and the power management module is bidirectionally signal-connected to the main control module. Specifically, the main power supply can provide operating voltage to all modules under normal operating conditions. When the main power supply fails, the main control module automatically switches to the backup power supply to power the core modules, ensuring that critical functions are not interrupted, ensuring normal power supply to the terminal, and avoiding data acquisition interruptions, communication failures, and other faults caused by power supply problems.

[0029] Reference Figure 1 and Figure 2 The main control module and the communication module have a bidirectional communication connection, the communication module has a bidirectional communication connection with the operation and maintenance center, and the communication module and the security module have a signal connection. Specifically, the main control module sends the data to be uploaded to the communication module, the communication module reports the communication status back to the main control module, and transmits the instructions received from the operation and maintenance center. The terminal can upload real-time data and alarm information to the operation and maintenance center through the communication module, and the operation and maintenance center can issue remote instructions to the terminal through the communication module. At the same time, the communication data needs to be encrypted by the security module before transmission.

Specifically, the clock module provides a precise time reference for the terminal. Through a two-way signal connection, the main control module can send time calibration commands and configure time formats to the clock module. Simultaneously, the clock module can provide real-time time information back to the main control module for event logging and scheduled task triggering. This two-way interaction ensures time accuracy. By setting up the local maintenance interface module as the physical channel for on-site maintenance, and through a two-way signal connection with the main control module, the main control module can output data to be read locally to the local maintenance interface module. Meanwhile, maintenance personnel can input debugging commands and read data from the main control module through the interface. This connection supplements remote maintenance, enabling on-site emergency debugging and troubleshooting. Status monitoring... The monitoring module collects the terminal's own status in real time and sends the data to the main control module. The main control module then determines whether the equipment is operating normally based on the data. The fault detection module reports the detection results and fault parameters to the main control module. Simultaneously, the main control module sends configuration commands to the fault detection module. The AC sampling module provides real-time power grid data as the initial basis for fault detection. The positioning and transformer area identification module provides precise fault location information to assist in fault localization. When a power outage, short circuit, or other fault occurs, the positioning and transformer area identification module can report the latitude and longitude of the faulty equipment and the transformer area number to the operation and maintenance center through the main control module, helping maintenance personnel quickly locate the fault point, shortening repair time, and providing accurate data for fault detection. Based on input and spatial coordinates, the accuracy of fault diagnosis is ensured. External switching signals are collected via a remote signaling module and transmitted to the fault detection module as auxiliary evidence for fault diagnosis. Direct signal transmission from the remote signaling module to the event recording and storage module ensures the timeliness and completeness of events. Furthermore, the remote signaling module can report the collected switching signals to the main control module in real time, ensuring the main control module has real-time control over the equipment's status. Simultaneously, the main control module can issue configuration commands or control signals to the remote signaling module to adjust its signal acquisition frequency, thus adapting to high-frequency monitoring needs during fault occurrences. The direct connection between the event recording and storage module and the fault detection and diagnosis module ensures real-time and complete storage of fault information, facilitating fault tracing. It provides core support for system reliability, avoiding latency and data risks associated with indirect connections. The event logging and storage module can provide historical data queries to the main control module, while the main control module can send storage commands to the storage module, thus achieving orderly data management and on-demand retrieval, preventing data loss or redundancy. The fault detection module can transmit early warning signals to the early warning and alert module, triggering alert actions. The early warning and alert module can then control the status indicator module to flash LEDs and sound an alarm, outputting intuitive alarm signals through audible and visual alarms, facilitating quick identification of anomalies by on-site personnel. This achieves localized, visually and audibly audible early warning, improving fault detection efficiency. Furthermore, the early warning and alert module can provide feedback on the early warning execution status to the main control module.Furthermore, the system can upload early warning information to the operations and maintenance center via a communication module, enabling remote alerts and establishing a connection between local and remote early warning systems to ensure timely response from operations and maintenance personnel.

[0031] Reference Figure 1 , Figure 2 and Figure 3 An electronic switch lock 2 is provided on the outer wall of the outer casing 1. The electronic switch lock 2 is electrically connected to the power management module and is bidirectionally signal connected to the main control module. Specifically, through the electronic switch lock 2, managers can remotely monitor the lock's status in real time and perform operations such as unlocking and locking. It also prevents unauthorized personnel from touching the internal precision components, ensuring the normal operation of the equipment. The electronic switch lock 2 requires specific authorization to open. The main control module can pre-store authorized personnel information, so even if unauthorized personnel touch the equipment, they cannot open the outer shell 1. When it is necessary to open, the main control module performs authorization verification, which ensures the security and traceability of opening the outer shell 1 through the door 9, and also improves the convenience of operation and maintenance. The power management module can provide a stable power supply to the electronic switch lock 2 to ensure its operation.

[0032] Reference Figure 3 , Figure 4 and Figure 5 A second fixing plate 5 is fixedly connected to the upper surface of the outer shell 1. A first fixing plate 4 is rotatably connected to the upper surface of the second fixing plate 5. The lower surface of the first fixing plate 4 is fixedly connected to the upper surface of the door 9. A rotating shaft 3 is rotatably connected inside both the outer shell 1 and the second fixing plate 5. The outer wall of the rotating shaft 3 is fixedly connected to the inside of the first fixing plate 4. The door 9 is fixedly connected to the outer wall of the rotating shaft 3. The outer wall of the door 9 is attached to the outer wall of the outer shell 1. A protective layer 6 is provided inside the outer shell 1. A heat insulation buffer layer 7 is provided on the outer wall of the protective layer 6. An electromagnetic shielding layer 8 is provided on the outer wall of the heat insulation buffer layer 7. Specifically, the outer shell 1 serves to fix the second fixing plate 5, which in turn supports and stabilizes the position of the rotating shaft 3. The second fixing plate 5 also supports the position of the first fixing plate 4, which in turn fixes the position of the cabinet door 9. The cabinet door 9, in turn, fixes the position of the rotating shaft 3. Therefore, when the electronic switch lock 2 is unlocked and the cabinet door 9 is opened, the first fixing plate 4 drives the rotating shaft 3 to rotate inside the outer shell 1, facilitating the opening of the outer shell 1. The protective layer 6, primarily composed of polyvinylidene fluoride, provides protection against... The harsh external environment provides a physical protective barrier against the corrosion of the terminal casing 1, while also having a self-cleaning function, which can reduce the adhesion of dust and dirt and reduce maintenance costs. The aerogel composite material used to make the heat insulation buffer layer 7 not only has excellent heat insulation performance, but also has a certain degree of flexibility and mechanical strength, which can provide good buffer protection for the casing 1 while being lightweight. The graphene-modified polymer material used to make the electromagnetic shielding layer 8 can achieve a good electromagnetic shielding effect and prevent the moisture and chemicals generated by the internal electronic components from corroding the casing 1, thus extending the service life of the casing 1.

[0033] Working Principle: First, the main power supply in the power management module converts the AC power in the distribution area into low-voltage DC power required by each module, providing a stable energy source and ensuring continuous operation of the terminals under normal conditions. When the main power supply fails, the backup power supply seamlessly switches over via a bidirectional signal connection between the power management module and the main control module, prioritizing power to the core modules and ensuring uninterrupted critical functions. The main control module sends core data collected by the terminals to the communication module, which then uploads it to the operations and maintenance center. For anomalies reported by the terminals, the operations and maintenance center issues instructions to the main control module via the communication module. The main control module then coordinates the relevant modules to execute these instructions and provides feedback. The communication module can also provide real-time communication status feedback to the main control module, allowing it to adjust data transmission strategies accordingly. The main control module also issues communication mode instructions to the communication module for different communication methods. Before transmitting data, the communication module encrypts the data via a signal connection with the security module to prevent data transmission errors. If data is stolen or tampered with during the process, the main control module receives data from each acquisition module and combines it with time information from the clock module to provide a unified time reference. This allows for real-time monitoring of the overall system operation status and the issuance of configuration commands to other modules. The connection between these modules not only meets functional requirements but also forms a closed loop for data flow. The fault detection and judgment module can determine the fault type and location based on AC sampled electrical quantity data, remote signaling module status signals, and station area information from the positioning module. It then uses a built-in algorithm to synchronize the analysis results to the main control module and the event recording and storage module. Simultaneously, after receiving the judgment results from the fault detection module, the early warning and reminder module immediately activates the LED indicator and buzzer alarm in the status indication module for local audio-visual reminders. It also sends alarm information to the remote platform via the communication module and allows maintenance personnel to interact with the main control module at the equipment site through the local maintenance interface. This enables local and remote collaborative early warning and improves fault handling efficiency. By setting up the electronic switch lock 2, the opening permissions of the device casing 1 can be digitally and intelligently managed, preventing unauthorized personnel from arbitrarily accessing the internal core modules. If the main power supply is interrupted, the backup power supply will be triggered to prioritize powering the electronic lock, ensuring that unlocking and maintenance can still be performed in emergencies. When maintenance personnel request unlocking via local or remote means, the verification module of the electronic switch lock 2 will send the request information to the main control module via the signal line. After receiving the request, the main control module will call the pre-stored authorization database for comparison, thereby ensuring the legality and traceability of the unlocking operation.
