Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to an intelligent energy terminal and its control method. Background Technology

[0002] Existing smart energy terminals are widely used in distributed photovoltaic systems, energy storage power stations, charging and swapping stations, and park energy management systems. As field-level data acquisition and communication control equipment, they typically employ a single power supply structure or rely on external UPS devices and relays for main / backup power switching. This type of solution has the following problems: 1. Slow power switching response: The switching control is located outside the equipment and relies on external devices for relay. The response time is long and it is susceptible to electromagnetic interference or poor contact. This may cause the equipment to lose power for a short time, causing the main control system to reset and affecting data continuity.

[0003] 2. Delayed alarm function: Most existing alarms are implemented by the main control software, which requires the main control to be powered on to be triggered. Once the equipment loses power, it cannot output alarm signals in time, making it difficult for maintenance personnel to detect power outage events in real time.

[0004] 3. Low integration and complex wiring: The main and backup power switching and alarm modules are scattered, with many external connections, making installation and debugging cumbersome and maintenance difficult, which is not conducive to the miniaturization and standardized deployment of equipment.

[0005] Therefore, existing smart energy terminals have significant shortcomings in terms of power supply reliability, response speed, and system integration. Summary of the Invention

[0010] In an optional implementation, it further includes: a power recovery indication module; after the power supply circuit is switched to the backup power supply, the automatic switching control module, upon determining that the voltage status detection result indicates that the main power supply voltage has returned to normal and has been maintained above a preset time threshold, drives the power supply circuit of the smart energy terminal to switch from the backup power supply to the main power supply, and simultaneously triggers the power recovery indication module to output a power recovery signal.

[0013] In an optional implementation, the power status detection module continuously samples the input voltage of the main power supply and the backup power supply, and periodically transmits the sampled data to the control and communication module for display or threshold comparison processing, so as to perform dynamic voltage trend analysis and early warning judgment.

[0014] Secondly, the present invention provides a control method for an intelligent energy terminal applied to any of the foregoing embodiments, comprising: acquiring voltage signals of the main power supply and the backup power supply of a dual power input module; detecting the voltage status of the main power supply and the backup power supply in real time through a power status detection module to obtain a voltage status detection result; when it is determined that the voltage status detection result is that the main power supply voltage is abnormal and the backup power supply voltage is normal, driving the power supply circuit to switch from the main power supply to the backup power supply through an automatic switching control module; triggering a power failure alarm module to output a power failure alarm signal at the same time as the power switching; and sending the voltage status detection result and the power failure alarm signal to a control and communication module so that the control and communication module performs data acquisition and event reporting based on a preset system processing logic.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0022] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Example 1 Figure 1 A functional block diagram of an intelligent energy terminal provided in an embodiment of the present invention is shown below. Figure 1 As shown, it includes: a dual power input module 100, a power status detection module 200, an automatic switching control module 300, a power failure alarm module 400, and a control and communication module 500.

[0024] The dual power input module is connected to the main power supply 10 and the backup power supply 20, and transmits electrical energy to the power status detection module.

[0025] The power status detection module monitors the voltage status of the main power supply and the backup power supply in real time and sends the voltage status detection results to the automatic switching control module.

[0026] When the voltage status detection result indicates that the main power supply voltage is abnormal and the backup power supply voltage is normal, the automatic switching control module drives the power supply circuit 30 of the smart energy terminal to switch from the main power supply to the backup power supply, and at the same time triggers the power failure alarm module to output a power failure alarm signal.

[0027] The control and communication module receives voltage status detection results and power failure alarm signals, and performs data acquisition and event reporting based on preset system processing logic.

[0028] The intelligent energy terminal provided in this invention is a highly reliable data acquisition and communication control device for the field layer of the energy internet. Its core lies in the deep integration of automatic dual-power switching and power failure alarm functions within the device, forming a closed-loop control link of "detection—decision—switching—alarm—reporting". This terminal is suitable for unattended, continuous operation scenarios such as distributed photovoltaic power stations, energy storage power stations, charging and swapping stations, and park energy management systems, aiming to solve problems such as data loss caused by power outages in existing single-power-source structures and delayed response of external switching devices.

[0029] Specifically, the dual power input module provides redundant power supply entry points, meaning it has two independent power input interfaces: a main power interface 101 and a backup power interface 102, used to connect to the main power supply (typically AC 220V AC mains) and a backup power supply (which can be AC ​​or a wide-range DC 110–370V power supply, such as from a UPS, DC power supply unit, or battery pack), respectively. The main power supply serves as the preferred power source under normal operating conditions, while the backup power supply is in hot standby mode, always energized and ready to operate at any time. The module design supports compatible access for different voltage types and levels, enhancing its adaptability to complex field power supply environments.

[0030] The power status detection module is deployed after the dual power input module and has the ability to continuously sample the main power supply voltage and the backup power supply voltage. Optionally, a high-precision voltage sensor or voltage divider circuit is used in conjunction with an ADC converter to periodically acquire the instantaneous values ​​of the two input voltages and determine whether they are within a preset safety range (e.g., the normal operating range of the main power supply is AC85V~265V). When the main power supply voltage is detected to drop below the threshold (e.g., due to power outage, line fault, or maintenance disconnection), or when overvoltage, undervoltage, or excessive fluctuation occurs, a "main power supply abnormality" status signal is immediately generated (a detection result of voltage status detection); at the same time, the stability and availability of the backup power supply are verified. The above status signals are transmitted to the automatic switching control module in real time in the form of electrical signals, serving as the core basis for switching decisions. In addition, this module can also output analog or digital signals for the control and communication module to read, for displaying voltage trends, generating early warning prompts, or recording historical data.

[0031] The automatic switching control module is the control center of the entire power management system. It receives voltage status detection results from the power status detection module and makes judgments based on preset logic. If the voltage status detection result shows that the main power supply voltage is normal, the automatic switching control module does not output drive signals, that is, it maintains the main power supply state. However, if the voltage status detection result shows that the main power supply voltage is abnormal and the backup power supply voltage is normal, the automatic switching control module will send a switching command to the power supply circuit to drive the electronic switches (such as MOSFETs, relays) inside the power supply circuit to disconnect the main power supply path and connect the backup power supply path. Generally, the power switching process is completed within milliseconds (e.g., response time <10ms) to avoid the main control system restarting due to a brief power outage and to ensure the continuity of data acquisition and communication.

[0032] Once the power switching action is triggered, a linkage trigger signal is simultaneously sent to the power failure alarm module to ensure strict synchronization between alarm and switching. In this embodiment of the invention, the power failure alarm module is used to realize hardware-level real-time alarm output. This module is independent of the software operation state of the main control system, and its operating power can also be maintained by an external auxiliary power supply, ensuring that the power failure alarm module can still work normally even if the main control unit completely loses power. After receiving the linkage trigger signal from the automatic switching control module, the power failure alarm module immediately outputs a power failure alarm signal. The power failure alarm signal can be connected to an external monitoring system, cloud platform, or on-site audible and visual alarm via cable to notify maintenance personnel at the first moment of power abnormality.

[0033] The control and communication module is the main control unit of the smart energy terminal, containing functional components such as a processor, memory, and communication interfaces (e.g., Ethernet, serial port). It is responsible for the overall operation and scheduling of the equipment. It can receive voltage sampling data and voltage status detection results from the power status detection module in real time, as well as action signals output from the power failure alarm module, and thus perform data acquisition and event reporting according to the preset system processing logic. Based on the above description, it can be seen that even during a main power outage, as long as the backup power supply continues to provide power, the control and communication module can continue to operate, completing event capture and reporting tasks, achieving true "uninterrupted power monitoring."

[0034] This invention integrates a dual power input module, a power status detection module, an automatic switching control module, and a power failure alarm module within the smart energy terminal, constructing an integrated linkage mechanism from power monitoring to switching actions to alarm output. This enables rapid takeover of the backup power supply and synchronous triggering of alarm signals when the main power supply is abnormal. This not only improves power supply continuity and fault response speed but also reduces the need for external components and enhances the system's compactness, stability, and maintainability.

[0035] In one alternative implementation, such as Figure 2As shown, the smart energy terminal also includes: a voltage regulator module 600.

[0036] The voltage regulator module regulates the power supplied by the power supply circuit and then supplies power to each functional module in the smart energy terminal.

[0037] In this embodiment of the invention, the voltage regulator module is a key power management component that ensures the stable operation of various functional units within the equipment. Its core function is to regulate and purify the raw voltage from the power supply circuit (the output after switching from the main power supply or backup power supply), providing a stable, low-noise, and isolated operating power supply that meets the requirements of the electronic system, ensuring that the control and communication modules and other sensitive circuits can still operate reliably in complex power supply environments.

[0038] In one optional implementation, the smart energy terminal further includes an alarm terminal for connecting to an external monitoring system and / or an audible and visual alarm device.

[0039] The power failure alarm module outputs a power failure alarm signal to an external monitoring system and / or audible and visual alarm device through the alarm terminal, so that the external monitoring system and / or audible and visual alarm device can trigger an alarm.

[0040] Specifically, the alarm terminal is the key physical interface for outputting fault information. It works in conjunction with the internal power failure alarm module to form a hardware-level alarm path independent of the main control system. This design ensures that in the instant the main power supply is interrupted and the equipment switches to the backup power supply, a clear power failure event signal can be immediately sent to the external monitoring system and / or audible and visual alarm devices, thereby achieving rapid response and remote monitoring.

[0041] In one alternative implementation, the smart energy terminal further includes a power restoration indicator module.

[0042] After the power supply circuit is switched to the backup power supply, the automatic switching control module, upon confirming that the voltage status detection result indicates that the main power supply voltage has returned to normal and has been maintained above the preset time threshold, drives the power supply circuit of the smart energy terminal to switch from the backup power supply to the main power supply, and simultaneously triggers the power recovery indication module to output a power recovery signal.

[0043] In the intelligent energy terminal provided by this invention, the power recovery indication module is a key component for realizing bidirectional linkage of power supply status and complete closed-loop event handling. This module works in conjunction with the automatic switching control module and the power status detection module. After the main power supply experiences an abnormal interruption and recovers, the system supports automatic switching back to the main power supply from the backup power supply. Simultaneously, a power recovery signal is output upon completion of the switch, signifying the end of the power failure period and the return of the equipment to normal operation. This design overcomes the deficiency of traditional unidirectional switching schemes that only provide alarms without recovery notifications, thus improving operational transparency and system self-healing capabilities.

[0044] Specifically, the core function of the power recovery indicator module is to output information indicating that the main power supply has been restored to normal operation, serving as the termination signal for power failure alarm events. It forms a symmetrical response mechanism with the aforementioned "power failure alarm module": the former indicates "fault occurrence," and the latter indicates "fault resolution," together constituting a complete power event lifecycle monitoring system. The output "power recovery signal" can be presented in various forms, such as LED indicators or communication messages, for external monitoring systems to identify and use for updating operating status, disabling alarms, and generating event archive records.

[0045] To prevent accidental switching back and frequent oscillations, when the current power supply path is the backup power supply, the automatic switching control module continuously receives main power supply voltage sampling data from the power status detection module. The system is only qualified to switch back to the main power supply if both of the following conditions are met simultaneously: 1. The main power supply voltage is within the normal range (e.g., AC85V~265V) and there are no fluctuations exceeding the limit; 2. This normal state lasts for more than a preset time threshold (e.g., 30 seconds, 60 seconds, or a configurable value). The purpose of setting the time threshold is to avoid misjudgments due to unstable recovery caused by temporary voltage flicker, instantaneous power restoration, or test power supply, preventing the system from repeatedly switching between the main and backup power supplies and ensuring operational stability.

[0046] The introduction of the power recovery indication module enables the intelligent energy terminal in this embodiment of the invention to not only have "fault response capability" but also "state return perception capability". It realizes the fully automated closed-loop control of the entire chain from "main power failure → automatic switching → power failure alarm → main power recovery → automatic switchback → recovery indication", which significantly improves the system's autonomy, observability and intelligent operation and maintenance level.

[0047] In one alternative implementation, the automatic switching control module includes a switching logic unit and a drive circuit.

[0048] The switching logic unit receives the voltage status detection result output by the power status detection module and generates a power selection command to the drive circuit according to the preset judgment rules.

[0049] When the drive circuit determines that the power selection command is for the backup power supply, it outputs a switching command to the power supply circuit so that the main power supply is switched to the backup power supply.

[0050] The switching logic unit is the "brain" of the automatic switching control module, responsible for determining the conditions for power switching and generating commands. Its input receives real-time voltage status detection results from the power status detection module. This information is typically represented in digital signals or analog voltages, indicating the real-time health status of the main and backup power supplies (e.g., undervoltage, power outage, overvoltage, etc.). Internally, it has a set of preset power selection rules, typical of which include: 1. If the main power supply voltage is normal → maintain main power supply; 2. If the main power supply voltage is abnormal (below a threshold) and the backup power supply voltage is normal → trigger switching to the backup power supply; 3. If the main power supply recovers and stabilizes for more than a preset time → trigger switching back to the main power supply (supports bidirectional switching logic); 4. Eliminates false judgment conditions (e.g., instantaneous fluctuations, noise interference), and has certain filtering and delay confirmation mechanisms. Based on these rules, the switching logic unit generates corresponding power selection commands (e.g., high / low level signals, pulse signals, or coded signals) and sends them to the drive circuit.

[0051] The drive circuit is the "actuator" of the automatic switching control module. It receives power selection commands from the switching logic unit and converts them into commands corresponding to the actual electrical actions to be performed by the power supply circuit. Its main function is to drive the power switching elements in the power supply circuit, such as relays or MOSFETs, to complete the switching operation between the main power supply and the backup power supply.

[0052] In one optional implementation, the preset system processing logic includes: recording the timestamp of each power switch, the duration of power supply, and the voltage values ​​before and after the switch, and generating a power event log. The control and communication module periodically or when a power failure alarm event is triggered reports the power event log to the background management system.

[0053] In this embodiment of the invention, the preset system processing logic is the core software logic within the control and communication module that enables traceability, auditability, and remote management of power events. This logic constructs a complete event recording-storage-reporting mechanism around power switching behavior, ensuring that every power supply anomaly and recovery process can be accurately captured and transmitted to the operation and maintenance management layer, providing reliable data support for system stability assessment, fault diagnosis, and energy management decisions.

[0054] When the automatic switching control module performs a primary / backup power supply switching operation, the control and communication module actively collects the following key parameters and generates a power event log based on the preset system processing logic: timestamp, power supply duration, and voltage values ​​before and after the switch. It can also collect switching type identifiers: marked as "Primary → Backup Switch" or "Backup → Primary Recovery," for easy classification and statistical analysis.

[0055] To balance communication efficiency and timely event response, the control and communication module adopts a dual-mode reporting strategy: 1. Event-triggered reporting (instant mode): When a power failure alarm occurs or a power switch is completed, the control and communication module immediately encapsulates the latest generated power event log; 2. Periodic polling reporting (periodic mode): During periods without emergencies, the control and communication module proactively sends summary reports to the backend according to a preset period (such as hourly or daily).

[0056] In one alternative implementation, the power status detection module continuously samples the input voltage of the main power supply and the backup power supply, and periodically transmits the sampled data to the control and communication module for display or threshold comparison processing, so as to perform dynamic voltage trend analysis and early warning judgment.

[0057] In this embodiment of the invention, the power status detection module not only undertakes the task of instantaneously determining whether the main and backup power supplies are abnormal, but also has the ability to continuously and periodically sample the input voltage and transmit the raw or processed voltage data to the control and communication module in real time. This mechanism enables the terminal to upgrade from "only responding to faults" to "predicting risks," realizing a technological leap from passive fault tolerance to proactive early warning.

[0058] Specifically, the power status detection module has a built-in high-precision voltage sensing unit (such as a resistor divider network, isolation amplifier, etc.) and an analog-to-digital converter (ADC) circuit. It can continuously sample the input voltage of the main power supply and the backup power supply at a fixed frequency (e.g., 10 to 100 times per second). The sampling process is not affected by automatic switching and is always online during normal operation, ensuring that the entire voltage fluctuation process is captured without omission. The sampled data is in the form of a time series, reflecting the trajectory of voltage change over time, and can be used to identify atypical abnormal patterns such as transient drops, slow decreases, and periodic fluctuations.

[0059] After receiving the voltage sampling data, the control and communication module performs the following two types of processing according to preset logic: (1) Display and visualization: Real-time voltage values ​​are pushed to the local display panel or remote monitoring interface for operation and maintenance personnel to view the current power supply quality intuitively; it supports drawing voltage history curves to show the voltage change trend over the past few minutes to hours; it also allows setting multi-level color indicators (green / yellow / red) to indicate the voltage health status and improve the human-computer interaction experience.

[0060] (2) Threshold comparison and anomaly identification: Static threshold judgment is performed for each sampling point (e.g., below AC85V is considered undervoltage, above AC265V is considered overvoltage) as the basis for whether to trigger switching; a dynamic threshold mechanism is introduced, for example, short-term fluctuations are allowed but continuous deviations are prohibited to avoid misjudgment; combined with the sliding window algorithm, the mean, variance, rate of change and other statistics are calculated to identify gradual deterioration trends (e.g., voltage gradually decreases due to line aging).

[0061] The control and communication modules can leverage accumulated voltage time-series data to perform higher-level trend modeling and behavior prediction. For example, they can use linear regression or exponential smoothing to fit voltage change trends and predict when voltage may drop below a safety threshold within the next few minutes; detect periodic oscillations (such as those caused by sudden load changes) to help determine abnormal operation of external equipment; identify transient events such as voltage drops, interruptions, and glitches, recording them as "disturbance events" and storing them in the log even if they do not reach the switching threshold; and calculate the integral area of ​​voltage deviation from the rated value per unit time to quantify the degree of power quality degradation. This type of analysis enables the system not only to respond to "already-occurring power outages" but also to detect "deteriorating power supply environments."

[0062] Based on the above trend analysis results, the control and communication module can generate a pre-emptive alarm signal, that is, issue a warning before the power supply completely fails. When the system determines that the main power supply voltage is showing a continuous downward trend and is expected to enter the abnormal range within N minutes, it triggers a "voltage degradation warning". This type of warning does not trigger power switching or activate the power failure alarm terminal (because there is no actual power failure), but it can buy valuable time for manual intervention.

[0063] Based on the description above, the overall workflow sequence of the smart energy terminal is as follows: 1. Normal operation phase: Main power supply is normal → Power status detection module continuously monitors → Automatic switching control module keeps the main power supply path open → Power failure alarm module is silent → Control and communication modules operate normally.

[0064] 2. Abnormal Triggering Phase: Main power supply fails / undervoltage, backup power supply provides normal power supply → power status detection module identifies abnormality → sends status signal to automatic switching control module.

[0065] 3. Switching Execution Phase: The automatic switching control module determines that the switching conditions are met → drives the power supply circuit to switch to the backup power supply → synchronously triggers the power failure alarm module to output a power failure alarm signal.

[0066] 4. Event handling phase: The control and communication module receives the power failure alarm signal → records the power event log → packages the alarm information and uploads it to the remote monitoring system.

[0067] 5. Recovery Phase: If the main power supply is restored and stabilized for a certain period of time, the system can automatically switch back to the main power supply and trigger a power recovery signal.

[0068] This invention eliminates the need for external UPS or relay boxes, integrating all power management functions into the terminal itself, reducing wiring complexity and improving installation efficiency. Dual power supply hot standby and millisecond-level switching minimize the risk of power outages, enhancing terminal reliability. A hardware-level linkage alarm mechanism ensures that signals are sent immediately upon power failure, unaffected by the main control status. Furthermore, it features event logging and remote reporting capabilities, facilitating fault tracing and maintenance management.

[0069] Example 2 This invention also provides a control method for a smart energy terminal. This method is applied to the smart energy terminal provided in Embodiment 1 above. The control method for the smart energy terminal provided in this invention will be described in detail below.

Figure 3 As shown, the specific steps include the following: Step S102: Obtain the voltage signals of the main power supply and backup power supply of the dual power supply input module.

[0071] Step S104: The voltage status of the main power supply and the backup power supply is detected in real time by the power status detection module to obtain the voltage status detection result.

[0072] Step S106: If the voltage status detection result indicates that the main power supply voltage is abnormal and the backup power supply voltage is normal, the power supply circuit is switched from the main power supply to the backup power supply through the automatic switching control module.

[0073] Step S108: At the same time as the power switch, the power failure alarm module is triggered to output a power failure alarm signal.

[0074] Step S110: The voltage status detection result and power failure alarm signal are sent to the control and communication module so that the control and communication module can perform data acquisition and event reporting based on the preset system processing logic.
