Description

A communication terminal for power service transmission and its optimization method Technical Field

[0001] This invention belongs to the field of communication terminal technology, specifically relating to a communication terminal for power service transmission and its optimization method. Background Technology

[0002] In power service access applications, 5G communication terminals are responsible for collecting power service data and remotely transmitting it to the main service station or target server via the 5G network. They also receive instructions from the main station to control the power service terminals. However, in practical applications where 5G communication terminals support power services, data transmission delays or even interruptions due to 5G terminal forwarding failures, performance degradation, network fluctuations, and network failures can directly impact the normal operation of power services or cause personal injury or property damage. Therefore, it is urgent to optimize and improve 5G communication terminals to eliminate occasional terminal or network failures and ensure the long-term stable and reliable operation of power service transmission.

[0003] Chinese invention patent application CN120857229A, published on October 28, 2025, discloses a power wireless communication terminal and its intelligent network selection method. This communication terminal has two modules: a first 5G module and a second 5G module. It intelligently selects the network based on the network environment and service requirements to achieve a stable wireless communication connection. This dual-channel design allows for automatic switching to the other module when one module fails or the network is poor. Furthermore, the main control unit implements intelligent network selection for the dual 5G modules based on a Q-learning algorithm. The state S in the Q-learning algorithm can be a comprehensive description of the current 5G network performance indicators (signal strength, throughput, latency, etc.) and environmental conditions (time, geographical location, etc.). This patent only describes adjusting the communication module, and that network performance and environmental conditions affect the selected module; in other words, it's simply to connect the terminal to a better network. However, the content transmitted in power services is complex and diverse. This method, which often relies solely on instantaneous network indicators for module switching, may lead to frequent network switching, resulting in unreliable and unstable terminal operation. Summary of the Invention

[0004] The purpose of this invention is to provide a communication terminal for power service transmission and its optimization method, so as to solve the problem of low reliability of communication terminals in the prior art.

[0005] To address the aforementioned technical problems, this invention provides a technical solution for a communication terminal used for power service transmission, specifically as follows: A communication terminal for power service transmission includes a main module and a secondary module, and further includes a situational awareness module and a disaster recovery redundancy module. The situational awareness module analyzes the collected data and, in conjunction with the working modes of the main and secondary modules, schedules the disaster recovery redundancy module to adjust the working status of the main and secondary modules. The working modes include a main module mode, a secondary module mode, and an intelligent mode. In the main module mode, only the main module establishes a network communication link by dialing up the network, while the secondary module is in standby mode. In the secondary module mode, only the secondary module establishes a network communication link by dialing up the network, while the main module is in standby mode. In the intelligent mode, both the main and secondary modules establish a network communication link by dialing up the network. The working status includes data transmission order and path. The collected data includes power services, network quality, data routing, and terminal temperature status. The power services include data type and service priority.

[0006] The beneficial effects of the above technical solution are as follows: Based on the power service transmission task, the present invention integrates a disaster recovery redundancy module and a situational awareness module within the communication terminal. This allows the situational awareness module to comprehensively consider information from various aspects, including power service, network quality, data routing, and terminal temperature status. The disaster recovery redundancy module adjusts the operational status of the main and secondary modules, including the data transmission sequence and path. The path refers to which module is selected for transmission. The modules work collaboratively to tailor different services and build different communication environments for different services, rather than simply switching to the best network. This ensures the quality of the power service transmission link, improves operation and maintenance efficiency, and enhances the operational reliability of the terminal.

[0007] Furthermore, the methods for analyzing the collected data and adjusting the working status of the main and secondary modules by scheduling the disaster recovery redundancy module in conjunction with the working modes of the main and secondary modules include: judging the data routes accessed by the terminal, prioritizing the transmission of data that conforms to the set data routes according to the priority of the data routes, and when the working mode of the main and secondary modules is intelligent mode, data of high priority data routes is transmitted through the main module, and data of low priority data routes is transmitted through the secondary module.

[0008] Furthermore, the service priority includes the priority of different communication protocols and the priority of different types of services under the same communication protocol; the method of analyzing the collected data and adjusting the working status of the main and secondary modules by scheduling the disaster recovery redundancy module in combination with the working modes of the main and secondary modules includes: when the working mode of the main and secondary modules is the main module mode or the secondary module mode, the data is transmitted through the main module or the secondary module according to the priority of different communication protocols and the priority of different types of services under the same communication protocol; when the working mode of the main and secondary modules is the intelligent mode, high-priority data is transmitted through the main module and low-priority data is transmitted through the secondary module.

[0009] Furthermore, the methods for analyzing the collected data and adjusting the working status of the main and secondary modules by scheduling the disaster recovery redundancy module in conjunction with the working modes of the main and secondary modules include: when the working mode of the main and secondary modules is intelligent mode, the network quality of the main and secondary modules is compared with the network quality requirements of the target server. When there are network fluctuations or failures, the module with better network quality is selected for transmission based on the comparison results; when the working mode of the main and secondary modules is either main module mode or secondary module mode, the network quality of the main and secondary modules is compared with the network quality requirements of the target server. When there are network fluctuations or failures, the transmission power of the main module or secondary module is increased accordingly based on the comparison results.

[0010] Furthermore, the disaster recovery redundancy module is used to make a preliminary judgment on the working status of the main module after the terminal self-test passes and the module program starts running normally, based on the normal status of the main module and the sub-module power supply, driver loading and AT command channel, the working mode settings of the main and sub-modules, and the normal status of the SIM card corresponding to the main module: if the main module and the sub-module power supply, driver loading and AT command channel are normal, the working mode of the main and sub-modules is set to main module mode or smart mode, and the SIM card corresponding to the main module is in normal status, then the main module is configured according to the main module configuration and dials up on the network; if the main module and the sub-module power supply, driver loading and AT command channel are normal, the working status of the main module and the sub-module is not ... If the command channel is normal, the main and secondary modules are set to main module mode or smart mode. If the SIM card corresponding to the main module is in abnormal status, an alarm for the corresponding SIM card will be triggered and logged. If the power supply, driver loading, and AT command channel of the main and secondary modules are normal, the main and secondary modules are set to secondary module mode. If the SIM card corresponding to the main module is in normal status, the main module will be in normal standby mode. If the power supply, driver loading, and AT command channel of the main and secondary modules are normal, the main and secondary modules are set to secondary module mode. If the SIM card corresponding to the main module is in abnormal status, the main module will be in standby mode, an alarm for the corresponding SIM card will be triggered, and logged.

[0011] Furthermore, the disaster recovery redundancy module is used to make a preliminary judgment on the working status of the secondary module after the terminal self-test passes and the module program starts running normally, based on the normal status of the power supply, driver loading, and AT command channel of the main module and the secondary module, the setting of the working mode of the main and secondary modules, and the normal status of the SIM card corresponding to the secondary module: if the power supply, driver loading, and AT command channel of the main module and the secondary module are normal, the working mode of the main and secondary modules is set to the secondary module mode or smart mode, and the SIM card corresponding to the secondary module is normal, then the secondary module is configured according to the main module and dials up on the network; if the power supply, driver loading, and AT command channel of the main module and the secondary module are normal, the secondary module is configured according to the main module and dials up on the network; if the power supply, driver loading, and AT command channel of the main module and the secondary module are normal, the secondary module is configured according to the main module and dials up on the network; if the power supply, driver loading, and AT command channel of the main module and the secondary module are normal, the secondary module is configured according to the main module and dials up on the network. If the command channel is normal, the main and secondary modules are set to secondary module mode or smart mode. If the SIM card corresponding to the secondary module is in abnormal status, an alarm for the corresponding SIM card will be triggered and logged. If the power supply, driver loading, and AT command channel of the main and secondary modules are normal, the main and secondary modules are set to primary module mode, and the SIM card corresponding to the secondary module is in normal status, the secondary module will be in normal standby mode. If the power supply, driver loading, and AT command channel of the main and secondary modules are normal, the main and secondary modules are set to primary module mode, and the SIM card corresponding to the secondary module is in abnormal status, the secondary module will be in standby mode, an alarm for the corresponding SIM card will be triggered, and logged.

[0012] Furthermore, if the power supply, driver loading, and AT command channel of the main module and the sub-module are normal, the working mode of the main module and the sub-module is set to the main module mode. If the SIM card corresponding to the main module is in an abnormal state, while the SIM card corresponding to the sub-module is in a normal state, then the sub-module will be allowed to register on the network and make a dial-up call.

[0013] Furthermore, if the power supply, driver loading, and AT command channel of the main module and the sub-module are normal, the working mode of the main and sub-modules is set to the sub-module mode. If the SIM card corresponding to the sub-module is in an abnormal state, while the SIM card corresponding to the main module is in a normal state, then the main module will be enabled to register on the network and make a dial-up call.

[0014] Furthermore, the methods for analyzing the collected data and adjusting the working status of the main and secondary modules by scheduling the disaster recovery redundancy module in conjunction with the working modes of the main and secondary modules include: adjusting the module's transmission power or turning off the module's power supply when the terminal temperature exceeds the limit.

[0015] Furthermore, the parameters that operators can set on the interactive interface of the communication terminal include terminal temperature threshold, data routing, communication protocol, and service priority.

[0016] To address the aforementioned technical problems, this invention also provides a technical solution for optimizing a communication terminal used for power service transmission, as follows: The optimization method for a communication terminal used for power service transmission includes: analyzing collected data and adjusting the operating status of the main and secondary modules in the communication terminal based on their operating modes; the operating modes include a main module mode, a secondary module mode, and an intelligent mode; in the main module mode, only the main module establishes a network communication link by dialing up the network, while the secondary module is in standby mode; in the secondary module mode, only the secondary module establishes a network communication link by dialing up the network, while the main module is in standby mode; in the intelligent mode, both the main and secondary modules establish a network communication link by dialing up the network; the operating status includes data transmission order and path; the collected data includes power services, network quality, data routing, and terminal temperature status, and the power services include data type, service characteristics, and service priority.

[0017] The beneficial effects of the above technical solution are as follows: The optimization method of the present invention integrates information from various aspects such as power business, network quality, data routing and terminal temperature status, and adjusts the working status of the main and secondary modules in the communication terminal, including the data transmission order and path. The path refers to which module to select for transmission, which is tailored to different services and builds different communication environments for different services, rather than simply being limited to switching the best network. This ensures the quality of power business transmission links, improves operation and maintenance efficiency, and enhances the operational reliability of the communication terminal.

Detailed Implementation

[0019] The communication terminal of this invention, in addition to a main module and a sub-module, also includes a situational awareness module and a disaster recovery redundancy module. The situational awareness module analyzes the collected data and, in conjunction with the working modes of the main and sub-modules, schedules the disaster recovery redundancy module to adjust the working status of the main and sub-modules. The working modes include a main module mode, a sub-module mode, and an intelligent mode. In the main module mode, only the main module establishes a network communication link while the sub-module is in standby mode. In the sub-module mode, only the sub-module establishes a network communication link while the main module is in standby mode. In the intelligent mode, both the main and sub-modules establish a network communication link. The working status includes data transmission order and path. The collected data includes power services, network quality, data routing, and terminal temperature status. Power services include data type and service priority. This invention can ensure the quality of power service transmission links, improve operational efficiency, and enhance the operational reliability of the terminal. To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings.

[0020] An implementation of a communication terminal for power service transmission: The present invention provides a communication terminal for power service transmission, the overall framework of which is shown in Figure 1, including a main module, a sub-module (or backup module, standby module), a main control module, and a power supply module.

[0021] The power module can supply power to the main control module, main module, and auxiliary module.

[0022] In this embodiment, the main module is a 5G communication module, which is the core component of the 5G communication terminal. Based on network registration and dialing, the 5G communication module establishes routes for terminal data and performs remote transmission via the operator's network. The secondary module serves as a redundancy backup and can be either a 4G or 5G communication module. Both the main and secondary modules are equipped with a corresponding SIM / UIM (collectively referred to as SIM). Hereinafter, the SIM corresponding to the main module is SIM1, and the SIM corresponding to the secondary module is SIM2.

[0023] The main control module is the MCU shown in Figure 1, which specifically includes a disaster recovery redundancy module and a dynamic sensing module. The MCU is also connected to a self-test module, a clock module, buttons, external interfaces, I / O ports, indicator lights, and a storage module; the storage module includes Synchronous Dynamic Random Access Memory (SDRAM) and Flash Memory (FLASH), and the indicator lights are LEDs.

[0024] The disaster recovery redundancy module can adjust the working modes of the main module and the secondary module, including main module mode, secondary module mode, and intelligent mode. Main module mode means that only the main module establishes a network communication link, while the secondary module is in standby mode. Secondary (backup) module mode means that only the secondary module establishes a network communication link, while the main module is in standby mode. Intelligent mode means that both the main module and the secondary module establish a network communication link, and the working status of the main module and the secondary (backup) module is determined by the situational awareness module's scheduling; the specific workflow is described later. Furthermore, as shown in Figure 2, the disaster recovery redundancy module supports configuring the network connection parameters for the main and secondary modules, including APN, username, password, network mode, frequency band lock, base station lock, and SIM card lock. By setting these parameters, the main and secondary modules of the terminal can access specific networks based on specific SIM cards, specific base stations, specific frequency bands, and specific modes, ensuring terminal network security.

[0025] The dynamic sensing module collects and analyzes data such as data type, traffic, service characteristics, priority, and network quality (signal quality, network latency, jitter, packet loss rate) based on power business data routing (source address, destination address, port). After comprehensive judgment, it schedules the disaster recovery redundancy module to adaptively adjust the terminal's operating status (including data transmission order and data transmission path, where the path is the selected module). Its page settings are shown in Figure 3.

[0026] The specific process of the entire communication terminal and its internal modules is shown in Figure 4, and is as follows: Step 1, the terminal is powered on, and the programs of each module of the terminal perform self-test and start-up. If the module self-test fails or the program starts abnormally, the terminal logs and lights up the alarm status indicator. At the same time, the LED flashes at a predetermined interval to indicate the specific abnormal status, so as to indicate the direction and content of the fault investigation.

[0027] Step 2: After the terminal self-test passes and the module program starts running normally, the disaster recovery redundancy management module first determines whether the power supply, driver loading, and AT command channel of the main module and the sub-module are normal. If an abnormality occurs, it logs the information and illuminates the alarm status indicator. If normal, it determines the working mode and then determines the status of SIM1 and SIM2 corresponding to the main and sub-modules. Specifically: 1) Preliminary judgment of the working status of the main module: If the power supply, driver loading, and AT command channel status are normal, the working mode is set to the main module mode or smart mode, and the corresponding SIM1 status is normal, then the main module sets up and dials the network according to the main module configuration (APN, username, password, network mode, frequency band lock, base station lock, SIM card lock); this status is called status 1.1.

[0028] If the power supply, driver loading, and AT command channel status are normal, and the working mode is set to main module mode or smart mode, and the corresponding SIM1 status is abnormal (not inserted or unavailable), then a main module SIM1 abnormal alarm will be issued and logged; this status is referred to as status 1.2.

[0029] If the power supply, driver loading, and AT command channel status are normal, the working mode is set to the secondary module mode, and the corresponding SIM1 status is normal, then the main module is in normal standby mode; this state is referred to as state 1.3.

[0030] If the power supply, driver loading, and AT command channel status are normal, the working mode is set to the secondary module mode. If the corresponding SIM1 status is abnormal (not inserted or unavailable), the main module will be in standby mode and an abnormal alarm will be triggered on SIM1 and logged. This state is called state 1.4.

[0031] 2) Preliminary judgment of the working status of the sub-module: If the power supply, driver loading and AT command channel status are normal, the working mode is set to sub-module or smart mode, and the corresponding SIM2 status is normal, then the sub-module will be set and network dialed according to the main module configuration (APN, username, password, network mode, frequency band lock, base station lock, SIM card lock); this status is called status 2.1.

[0032] If the power supply, driver loading, and AT command channel status are normal, and the working mode is set to sub-module or smart mode, and the corresponding SIM2 status is abnormal (not inserted or unavailable), then a sub-module SIM2 abnormal alarm will be issued and logged; this status is referred to as status 2.2.

[0033] If the power supply, driver loading, and AT command channel status are normal, the working mode is set to the main module mode, and the corresponding SIM2 status is normal, then the sub-module is in normal standby mode; this state is called state 2.3.

[0034] If the power supply, driver loading, and AT command channel status are normal, and the working mode is set to the main module mode, and the corresponding SIM2 status is abnormal (not inserted or unavailable), then the sub-module will be in standby mode, and an abnormal alarm will be triggered for SIM2 and logged; this state is called state 2.4.

[0035] 3) Comprehensive Judgment of Main and Sub-module Working Status: To maximize the network communication of the 5G communication terminal, a comprehensive judgment is made based on the working status of the main and sub-modules, and special operations are performed as follows: When the working mode is set to main module mode, and the main module's working status is 1.2 (SIM card abnormality) while the sub-module's working status is 2.3 (normal standby), to ensure the terminal's network availability, the disaster recovery redundancy module will activate an emergency program. Ignoring the current mode setting, it will call the configuration parameters stored for the sub-module to perform network registration dialing for the sub-module and record the logs. At this time, the terminal enters a special emergency working state. When the working mode is set to sub-module mode, and the sub-module's working status is 2.2 (SIM card abnormality) while the sub-module's working status is 1.3 (normal standby), to ensure the terminal's network availability, the disaster recovery redundancy module will activate an emergency program. Ignoring the current mode setting, it will call the configuration parameters stored for the main module to perform network registration dialing for the main module and record the logs. At this time, the terminal enters a special emergency working state.

[0036] It should be noted that, in terminal applications, the network dialing parameters for the primary and secondary modules can be pre-configured and stored in the terminal's storage module via factory settings or user prompts. The system ensures that, in any operating mode, when either communication module needs to be activated, its corresponding configured parameters can be invoked to perform the network dialing operation.

[0037] The initial judgment results of the above-mentioned working states are shown in Table 1.

[0038] Table 1

[0039] Step 3: After the main and auxiliary modules of the terminal have made a comprehensive judgment and are working normally, the situation awareness module collects and analyzes data such as data routing, power business (including data type, traffic, business characteristics, priority), network quality (signal quality, network latency, jitter, packet loss rate), and terminal status (specifically terminal temperature status). After comprehensive judgment, it schedules the disaster recovery redundancy module to adaptively adjust the terminal's working status.

[0040] Among them, "traffic" is used to sense the scale of business data, serving as a reference for predicting network load and dynamically allocating communication link bandwidth; "business characteristics" are used to characterize the transmission behavior pattern and service quality requirements of the business, such as whether it is an uninterruptible service, its sensitivity to latency or jitter, and transmission cycle. The situational awareness module integrates business priority and business characteristics to collaboratively determine the data transmission scheduling strategy (such as whether it is permissible to sacrifice instantaneous rate to ensure reliability, or whether it is permissible to allow a short buffer while waiting for a high-quality network). For example, for power remote control commands, its business characteristics can be marked as "extremely low latency, zero interruption tolerance"; for the transmission of power grid fault waveform data files, its characteristics can be marked as "high bandwidth, background transmission allowed, and tolerance for certain delays". These characteristic parameters can be pre-configured in the terminal's interactive interface (see Figure 3).

[0041] On the terminal situational awareness module page (i.e., the human-machine interface), parameters such as data routing, power business communication protocol, business priority, business traffic, and communication template can be set, and multiple power protocol services can be configured.

[0042] Multiple data routes can be configured, each with different priorities. For example, three data routes can be configured, as shown in Table 2. These routes are ordered from highest to lowest priority. The situational awareness module identifies the data routes accessed by the terminal. Data conforming to the configured routing rules is prioritized for transmission by the disaster recovery redundancy management module. Data that does not conform to any preset routing rules is treated as "other data" with the lowest priority and included in the default transmission strategy. The disaster recovery redundancy management module adaptively adjusts according to its configured operating mode to ensure that high-priority route data is transmitted via high-reliability, low-latency 5G communication networks of the main module. Low-priority data routes or other data are transmitted via 4G communication networks of the secondary module, ensuring reliable power service transmission quality based on the dual-module configuration. In other words, in intelligent working mode, the main module and the secondary module simultaneously establish and maintain network communication links and are in an online standby state. The situational awareness module schedules high-priority routing data to be transmitted through the 5G link of the main module based on real-time analysis results, while routing low-priority data or other data to the 4G link of the secondary module. The two work together to ensure transmission quality.

[0043] Table 2

[0044] Priorities can also be set for different communication protocols, as well as for different types of services under the same communication protocol. As shown in Table 3, for example, the power service communication protocol can be set to IEC 60870-5-104, with a high service priority, and the service template can be the address of different types of service information bodies in IEC 60870-5-104. When the disaster recovery redundancy module is in main or secondary module working mode, the terminal can only transmit power service data through one communication link between the main or secondary module. At this time, the terminal judges based on the access data, prioritizing the transmission of the high-priority IEC 60870-5-104 data set above, and further prioritizing transmission based on the service importance level in the power service template (e.g., remote control > remote signaling, telemetry). When the disaster recovery redundancy module is in intelligent working mode, high-priority IEC 60870-5-104 data is preferentially transmitted through the main module's 5G high-reliability, low-latency communication network. At the same time, it is further prioritized for transmission according to the importance level of the business in the power business template (e.g., remote control > remote signaling, telemetry). Low-priority power business data or other data are transmitted through the secondary module's 4G communication, ensuring the quality of power business transmission based on the reliability of the dual modules.

[0045] Table 3

[0046] If other power business communication protocols such as Modbus or IEC 60870-5-101 are set, the business communication template refers to IEC 60870-5-104 mentioned above. The business type flag can be set as a unique identifier for protocol data, such as function code, information body address, ID, etc.

[0047] Furthermore, parameters such as signal quality, network latency, jitter, and packet loss rate can be set on the terminal's network quality page. The terminal monitors and analyzes these parameters to adaptively adjust the power service transmission link based on network quality. For example, setting the network signal quality to -100dBm, the network latency threshold to 60ms, the jitter threshold to 10ms, and the packet loss rate to 0.001% means that when the terminal is in smart mode, the main and auxiliary modules compare their own signal quality with the target server's ping test results and the required values. Based on the comparison of network quality, when there are network fluctuations or network failures, the power service data is switched to the module with the better network quality and transmitted according to service priority, with logs recorded. When the terminal is in smart mode, the main and auxiliary modules monitor their own signal quality, network latency, and other parameters in real time and compare the monitoring results with preset thresholds. When any one or more parameters (such as signal strength lower than the set value or latency higher than the set value) do not meet the requirements, it is determined to be a network fluctuation or failure. At this time, the power service data is switched to the module with better network quality and transmitted according to service priority, with logs recorded. When the terminal is in main module or sub-module working mode, if the network quality parameters are detected to be close to or worse than the preset threshold, the state is recorded, and the transmission power is gradually increased or increased according to the preset step size by sending specific AT commands to the working module, thereby attempting to improve the link quality, and in the process, the transmission of high-priority data is prioritized.

[0048] In addition, the situational awareness module page allows setting temperature thresholds for key terminal components, including CPU temperature thresholds and communication module temperature thresholds. It monitors temperatures in real time, and when the temperature is too high, it adjusts the module's transmission power or shuts down the module's power supply while ensuring communication quality, so as to ensure terminal processing performance. At the same time, it performs alarms and log recordings.

[0049] An Implementation Method for Optimizing a Communication Terminal for Power Service Transmission: The core idea of ​​this invention's optimization method for a communication terminal for power service transmission is to analyze collected data and adjust the operating status of the main and secondary modules in the communication terminal based on their respective operating modes. The operating modes include a main module mode, a secondary module mode, and an intelligent mode. In the main module mode, only the main module establishes a network communication link by dialing up, while the secondary module remains in standby mode. In the secondary module mode, only the secondary module establishes a network communication link by dialing up, while the main module remains in standby mode. In the intelligent mode, both the main and secondary modules establish a network communication link by dialing up. The operating status includes data transmission order and path. The collected data includes power service data, network quality, data routing, and terminal temperature status. The power service data includes data type, service characteristics, and service priority.

[0050] For a more detailed description of the process, please refer to the introduction of "A Communication Terminal for Power Business Transmission". This implementation method will not repeat the details.

[0051] In summary, this invention optimizes the 5G communication terminal for power systems. On the hardware side, a second communication module is added for disaster recovery redundancy. On the application side, a disaster recovery redundancy module and a situational awareness module are added. Through collaboration between the terminal and the modules, the availability of the wireless network transmission channel for power services is maximized. Simultaneously, by using preset parameters to monitor and analyze data routing, power service priority, network quality performance, and terminal status in real time, the sequence and path (module) of power service data transmission are dynamically adjusted, improving the quality and reliability of the power service transmission link and enhancing the robustness of power grid operations.
