Description

Technical Field

[0001] This utility model relates to the field of battery charging and discharging technology, and in particular to an intelligent charging and discharging device for a storage battery lamp. Background Technology

[0002] In emergency lighting systems of large industrial facilities such as nuclear power plants, battery-powered lights are critical equipment for ensuring safe operation. These lights are numerous, come in various models, and often require long-term storage from delivery to installation. During this period, a strict "four-charge, three-discharge" maintenance procedure must be performed regularly; otherwise, the batteries are prone to damage due to aging or performance degradation. Traditional manual maintenance methods are not only cumbersome and labor-intensive, but also prone to human error due to their long cycles and repetitive nature, seriously affecting equipment reliability.

[0003] Currently, the industry commonly uses temporary charging and discharging test platforms, connecting multiple lamps via terminal blocks for centralized operation. This method requires dedicated personnel to monitor the entire process in an isolated environment, manually performing power-off, power-on, and recording operations, and is equipped with fire extinguishing facilities to address the risk of battery explosions or fires. However, this method has significant drawbacks: its high reliance on manual labor leads to inefficiency and frequent errors; the lack of real-time monitoring of risks such as leakage and temperature results in significant electrical fire hazards; parameter mismatch when different lamp models are mixed can damage the batteries; and large-scale maintenance is prone to overdue or missed maintenance, making standardized management difficult.

[0004] Faced with the aforementioned problems, the market currently lacks intelligent charging and discharging equipment specifically designed for battery-powered lighting fixtures, and traditional methods cannot meet the safety, efficiency, and cost control requirements of large power plants. Therefore, developing an intelligent charging and discharging device integrating automated control, real-time monitoring, and remote management functions has become an inevitable direction for addressing these pain points. The intelligent charging and discharging device for battery-powered lighting fixtures proposed in this application aims to achieve standardization, unmanned operation, and traceability of the maintenance process through automated control, an electrical fire monitoring unit, and cloud platform data management, thereby comprehensively improving the safety and economy of equipment maintenance.

Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0023] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0024] Please see Figures 1 to 2 This invention provides an intelligent charging and discharging device for a battery-powered lamp, comprising a charging and discharging platform 10 and a charging and discharging control cabinet 20. The charging and discharging platform 10 is provided with an interface for connecting the battery-powered lamp. The charging and discharging control cabinet 20 is connected to the charging and discharging platform 10 via a charging cable 30 and a communication bus 40. The charging and discharging control cabinet 20 is equipped with a controller 21, a touch screen 22, and a relay 23. The touch screen 22 provides a human-machine interface for the controller 21. The relay 23 is mounted on the charging cable 30 and is controlled by the controller 21. The controller 21 receives the charging and discharging parameters input from the touch screen 22 and compares them with the charging and discharging data of the battery-powered lamp connected to the charging and discharging platform. Based on the comparison result, the controller controls the relay 23 to perform the closing or opening action.

[0025] Specifically, in this embodiment of the invention, the charging / discharging platform 10 and the charging / discharging control cabinet 20 work together. The charging / discharging platform 10 acts as an execution terminal, establishing a physical connection with various battery lamps through its dedicated interface, providing a basic carrier for charging and discharging operations. The charging / discharging control cabinet 20 acts as the system brain, supplying power to the charging / discharging platform 10 through the charging cable 30, and simultaneously establishing a bidirectional data link through the communication bus 40 to achieve real-time monitoring of the status of the charging / discharging platform 10 and the issuance of commands. It constitutes the hardware foundation of the entire charging / discharging device.

[0026] Furthermore, within the charging / discharging control cabinet 20, the controller 21, touchscreen 22, and relay 23 form a closed-loop control system. The touchscreen 22, acting as a human-machine interface, provides users with an intuitive interface for parameter configuration and displaying charging / discharging status data. Users can easily set the charging / discharging parameters for different battery lights through it. These parameter commands are transmitted to the controller 21 in real time. The controller 21, as an information processing node, not only receives the charging / discharging parameter settings from the touchscreen 22 but also continuously collects real-time charging / discharging data from each charging / discharging platform 10 via the communication bus 40. After comprehensively analyzing and calculating these two types of information (i.e., comparing their magnitudes: whether the collected charging and discharging data is within the set charging and discharging parameter range), controller 21 generates corresponding control commands (e.g., if the voltage in the collected charging and discharging data is lower than the set value of the charging and discharging parameters, it means that the battery is low and charging can be initiated; if the voltage is too high, the power is cut off; simultaneously, considering the charging and discharging process and the characteristics of the battery and lighting fixtures, the system enters the lighting discharge state when the power is cut off. Similarly, the temperature parameters in the charging and discharging data can reflect the status of the battery, lighting fixtures, and charging cables. A rise in temperature may be due to heat accumulation during the charging process or an electrical fault. This can be prevented by reducing the charging power and cutting off the power, thus avoiding the risk of electrical fire caused by further temperature increases), controller 21 drives relay 23 to perform specific closing or opening actions, thereby automatically completing the switching of charging, discharging, and pausing charging and discharging cycles. This automated link from parameter setting to physical execution replaces the traditional manual timed operation mode.

[0027] Thus, through the cooperation of controller 21 and touch screen 22, the complex "four-charge, three-discharge" process of battery-powered lighting fixtures can be easily managed through parameterized settings, reducing the user's operational threshold and workload. Furthermore, the reliable linkage between controller 21 and relay 23 ensures the accuracy and timing of the charging and discharging process, avoiding overcharging, undercharging, or maintenance omissions caused by human error such as forgotten operation or incorrect timing, thereby improving the quality and reliability of maintenance work. The entire device, through hardware and software integration, achieves standardized and automated management of battery-powered lighting fixture maintenance, demonstrating efficient, stable, and safe application results.

[0028] Please see the appendix Figure 2 In one embodiment, the system further includes a current monitoring unit, which comprises a current transformer 24 installed on the charging branch within the charging control cabinet 20, and a current acquisition module 25 connected to the current transformer 24 and communicating with the controller 21. The current acquisition module 25 is configured to record the charging current and send a signal to the controller 21 to trigger an alarm and terminate charging when the charging current exceeds a set threshold.

[0029] Specifically, in this embodiment of the invention, the current monitoring unit is a key component ensuring the safety and reliability of the charging and discharging process, providing protection through precise measurement. The current transformer 24, as the sensing terminal of the monitoring unit, can be directly installed on each charging branch within the charging and discharging control cabinet 20. Its function is to sense the charging current of each battery lamp in real time and convert this physical quantity into a standard signal that can be processed by subsequent equipment. This enables monitoring of each independent charging circuit, providing a data foundation for the analysis and control of the subsequent charging and discharging process.

[0030] Furthermore, the current acquisition module 25 is used for data processing and relay. It is directly connected to the current transformer 24 and continuously receives current signals from each branch. On the one hand, it can act as a data logger, for example, continuously recording the changes in charging current at intervals of 30 seconds, thereby forming complete historical data of the charging process and providing data support for subsequent maintenance analysis and life prediction. On the other hand, it can act as a safety barrier, with preset charging current thresholds for different battery and lighting models. When the real-time acquired current data exceeds the safety threshold, the current acquisition module 25 can immediately convert this signal into digital alarm information and transmit it to the upper controller 21 for processing via the communication line.

[0031] Thus, a closed-loop system is formed between the current transformer 24, the current acquisition module 25, and the controller 21. The current transformer 24 is responsible for sensing charging and discharging data, the current acquisition module 25 is responsible for judging and reporting the charging and discharging data, and the controller 21 is responsible for making decisions and executing the charging and discharging data. When an over-limit alarm signal is received from the current acquisition module 25, the controller 21 will immediately activate the predetermined safety mechanism, send a trip command to the relay 23, and quickly cut off the power supply to the corresponding branch to maintain electrical safety. Through the rapid linkage mechanism from monitoring to execution, the risk of overcurrent caused by short circuits, internal battery faults, or component abnormalities can be effectively prevented. This not only protects the battery and lighting fixtures from damage but also fundamentally eliminates the potential electrical fire hazard caused by excessive current, thereby improving the safety and automation level of the entire charging and discharging process.

[0032] Please see the appendix Figure 2In one embodiment, the system further includes an electrical fire monitoring unit, which comprises an electrical fire monitor 26, a grating-type fiber optic temperature sensor 11, and a residual current transformer 27. The grating-type fiber optic temperature sensor 11 is mounted on the cabinet of the charging / discharging platform 10 via a bracket and is used to monitor the ambient temperature. The residual current transformer 27 is installed at the main circuit breaker of the charging / discharging control cabinet 20 and is used to monitor leakage current. The grating-type fiber optic temperature sensor 11 and the residual current transformer 27 are respectively communicatively connected to the electrical fire monitor 26. The electrical fire monitor 26 is communicatively connected to the controller 21 and is configured to alarm and terminate the charging process when the detected temperature or leakage current value exceeds the limit.

[0033] Specifically, in this embodiment of the invention, the electrical fire monitoring unit serves as the core of the entire charging and discharging device. Through multi-sensor collaborative monitoring, it constructs a multi-dimensional defense system against electrical fire hazards. It consists of three main components: an electrical fire monitor 26, a grating-type fiber optic temperature sensor 11, and a residual current transformer 27. The grating-type fiber optic temperature sensor 11, acting as a temperature sensing unit, is distributed and installed inside the cabinet of the charging and discharging platform 10 via a bracket. Its detection point is directly aligned with the battery lamp body, thereby achieving accurate real-time monitoring of the battery body and surrounding environment temperature during charging and discharging. The residual current transformer 27, acting as a leakage current sensing unit, can be integrated into the main power circuit breaker of the charging and discharging control cabinet 20. It is responsible for monitoring changes in the leakage current to ground in the entire system's power supply circuit, effectively detecting insulation faults caused by aging or damage to the line insulation.

[0034] Furthermore, the grating-type fiber optic temperature sensor 11 and the residual current transformer 27 convert the collected temperature signal and leakage current signal into digital information, respectively, and transmit them to the electrical fire monitor 26 via a communication line. The electrical fire monitor 26, acting as the data processing and judgment center, continuously receives and analyzes data from the front-end sensors. It has pre-set alarm parameters for the upper temperature limit and leakage current threshold. When the processing and analysis detects that any temperature signal or total leakage current exceeds the upper limit threshold, a response mechanism can be immediately activated: for example, the first level is an audible and visual alarm, issuing a strong warning to alert on-site personnel; the second level is to execute protective actions, such as generating a priority digital fault signal and sending it to the controller 21 via the communication bus 40 to operate the relay 23 to trip and disconnect the circuit.

[0035] Thus, through the communication connection between the electrical fire monitor 26 and the main controller 21, a process from fault detection to safe execution is achieved. Upon receiving an over-limit alarm signal from the fire monitor, the controller 21 treats it as a highest-priority interrupt command, immediately interrupting the current charging / discharging process and issuing a trip command to the driven relay 23, instantly cutting off the power supply. Furthermore, through a closed-loop linkage mechanism from distributed monitoring to centralized processing and rapid execution, the time from discovering a hidden danger to handling the emergency is shortened. This effectively curbs accidents such as line burnout, battery explosion, and even electrical fires that may be caused by continuous overheating or leakage expansion. It addresses safety risks that are difficult to avoid in traditional maintenance through intelligent multi-layered protection, thereby improving the safety of the entire charging / discharging process.

[0036] Please see the appendix Figure 2 In one embodiment, the electrical fire monitoring unit further includes a grating-type fiber optic temperature transmitter 28, which is connected to multiple grating-type fiber optic temperature sensors 11 via optical fibers. The grating-type fiber optic temperature transmitter 28 uses time-division scanning technology to process the temperature data of the multiple grating-type fiber optic temperature sensors 11 and communicates with the electrical fire monitor 26.

[0037] Specifically, in this embodiment of the invention, the grating-type fiber optic temperature transmitter 28 serves as a node for distributed temperature monitoring and centralized management within the electrical fire monitoring unit. It connects via fiber optic cables to multiple grating-type fiber optic temperature sensors 11 arranged on the racks of each charging / discharging platform 10, forming a monitoring network covering all locations. Its function is to employ time-division scanning technology to sequentially excite and collect data from each temperature sensor in the monitoring network according to a preset cycle, demodulate and calculate the grating signals returned by the sensors, and thus obtain the actual temperature value at each monitoring point.

[0038] In this way, time-sharing scanning avoids the redundancy and cost of configuring and processing each temperature measurement point separately, improving equipment utilization and economy while ensuring monitoring accuracy and real-time performance. In conjunction with the electrical fire monitor 26, it enables the monitor 26 to acquire pre-processed, uniformly formatted temperature data, facilitating decision-making functions such as processing judgment, risk warning, and linkage control. This not only strengthens the monitoring capability for localized overheating risks but also enhances the reliability, scalability, and maintenance convenience of the entire electrical fire monitoring unit through optimized configuration.

[0039] Please see the appendix Figure 2 In one embodiment, the system further includes a remote monitoring unit, which includes a switch 50 and a 5G module 60 connected to the controller 21. The controller 21 is configured to transmit charging and discharging data to a remote terminal 80 via the 5G module 60 and to receive control commands from the remote terminal 80.

[0040] Specifically, in this embodiment of the invention, the remote monitoring unit consists of a switch 50 and a 5G communication module, both of which are physically connected to and interact with the controller 21. The switch 50 is responsible for distributing and transmitting data within the local network, ensuring communication between the controller 21 and the charging and discharging platforms 10 of each subsystem; the 5G module 60 serves as a wireless transmission interface, extending the data link to the wide area Internet to achieve remote interaction.

[0041] More specifically, the controller 21 can integrate a 5G module 60 to upload real-time charging and discharging data to the remote terminal 80 at high speed and low latency. This data includes key operating parameters such as voltage, current, and temperature, and the transmission process ensures data integrity and real-time performance. Simultaneously, the high bandwidth of the 5G network supports larger capacity data transmission, enabling the remote terminal 80 to comprehensively monitor the charging and discharging process status, providing a basis for subsequent decision-making and control.

[0042] When receiving control commands from the remote terminal 80, the controller 21 acquires the command information in real time through the 5G module 60, and processes, parses, and executes related operations. This allows users to flexibly adjust charging and discharging strategies, start and stop the charging and discharging system, or set charging and discharging operating parameters remotely, thereby improving the system's controllability and response efficiency. The remote monitoring unit not only realizes data transmission but also constructs a closed-loop control link, enabling the charging and discharging system to have remote management and scheduling capabilities.

[0043] In one embodiment, the remote monitoring unit further includes a network camera 70, which is installed on the top of the charging and discharging control cabinet 20 and connected to the switch 50. The network camera 70 is used to collect the QR code information of the battery lamps and upload it to the charging and discharging management database through the 5G module 60.

[0044] Specifically, in this embodiment of the utility model, the network camera 70 serves as the visual perception component of the remote monitoring unit. It is installed on the top of the charging and discharging control cabinet 20, thereby enabling it to obtain a wide field of view and completely cover the battery lamps placed on the charging and discharging platform 10 below it.

[0045] More specifically, the network camera 70 can be connected to the switch 50 via a wired connection, becoming a node in the local area network of the charging and discharging device. This connection method ensures stable and high-speed transmission of video data streams, avoiding signal interference or delays that may occur with wireless connections. The function of the network camera 70 is to automatically identify and capture the QR code label affixed to the casing of each battery-powered lamp. Through its built-in image sensor and lens, it can capture and parse the QR code image, converting visual information into digital identity information containing key attributes such as lamp model, serial number, and production batch.

[0046] Furthermore, the collected QR code data is transmitted to the 5G module 60 via the switch 50. Leveraging its high bandwidth and low latency wireless transmission capabilities, the 5G module 60 uploads the data to a remote charging and discharging management database. Thus, the network camera 70, switch 50, and 5G module 60 form a link from visual acquisition to data upload.

[0047] Thus, by using network cameras 70 in the remote monitoring unit to perform image recognition on the battery-powered lighting fixtures, intelligent material management is achieved. This replaces the inefficient methods of traditional manual recording or individual scanning, enabling batch, automatic identification and entry of the identities of large quantities of battery-powered lighting fixtures. Furthermore, the digital identity information of the battery-powered lighting fixtures is automatically captured when they enter the maintenance process and matched with all operational data (such as voltage, current, and time) for that charge-discharge process, ultimately forming a complete and traceable electronic maintenance file in the cloud-based charge-discharge management database. This not only improves the efficiency and accuracy of data entry and eliminates information errors that may result from manual recording, but also establishes a full lifecycle digital file for each battery-powered lighting fixture, serving as the data foundation for quality tracking and maintenance cycle calculation of battery-powered lighting fixtures.

[0048] In one embodiment, the charging and discharging platform 10 is provided with an expansion interface, and multiple charging and discharging platforms 10 are cascaded through the expansion interface.

[0049] Specifically, in this embodiment of the invention, the expansion interface on the charging / discharging platform 10 adopts a standardized design, allowing multiple charging / discharging platforms 10 to be connected in series via cables to form a unified charging / discharging platform group 10. This cascading approach enables a single charging / discharging control cabinet 20 to simultaneously manage the charging and discharging maintenance of dozens or even hundreds of battery lamps on multiple charging / discharging platforms 10, thereby increasing the scale of battery lamp processing at one time and meeting the needs of large-scale, centralized maintenance in scenarios such as large power plants. The expansion interface not only transmits charging and discharging energy but also serves as a communication connection for control signals and status data between charging / discharging platforms 10, ensuring that even in a system with multiple cascaded charging / discharging platforms 10, the controller 21 can still accurately identify and independently control the charging / discharging battery lamps at each end node.

[0050] In one embodiment, the controller 21 has multiple preset charging and discharging modes, and the charging and discharging modes can be selected and called through the touch screen 22 to adapt to the charging and discharging needs of different types of battery lamps.

[0051] Specifically, in this embodiment of the invention, the multiple pre-set charging and discharging modes in the controller 21 form the software foundation for the adaptability of the charging and discharging device. Each charging and discharging mode corresponds to different models and specifications of battery lamps, with key parameters such as optimal charging and discharging curves, voltage and current thresholds, and duration. Users can directly select the corresponding charging and discharging mode from the preset menu based on the battery lamp model via the touchscreen 22 interface to complete the configuration. This transforms complex parameter settings into a simple selection operation, lowering the operational threshold and avoiding human input errors. After calling a specific charging and discharging mode, the controller 21 automatically controls the relay 23 according to its defined logic and parameters, executing a complete "four-charge, three-discharge" or other customized charging and discharging process. This ensures that different types of battery lamps receive the most suitable maintenance process, thereby improving the standardization and accuracy of battery lamp maintenance.

[0052] In one embodiment, the remote terminal 80 is equipped with cloud monitoring software for displaying charging and discharging data and providing a remote configuration interface for the touchscreen 22.

[0053] Specifically, in this embodiment of the invention, the remote terminal 80, such as a smartphone or computer, has cloud monitoring software installed on it. This software connects to the on-site 5G module 60 via the internet and can receive charging and discharging data from the controller 21 in real time. Its function is to replicate the human-machine interface of the on-site touchscreen 22, providing a remote configuration interface. Users can remotely view and modify charging and discharging parameters, select or switch preset charging and discharging modes, and perform emergency power-off operations. This expands the management scope and response speed of the charging and discharging system, enabling professionals to centrally monitor and schedule the charging and discharging process of the battery-powered lighting fixtures, improving convenience and providing remote handling capabilities.

[0054] In summary, this utility model provides an intelligent charging and discharging device for battery-powered lighting fixtures. Through an integrated charging and discharging platform and control cabinet, it optimizes the charging and discharging maintenance of large-volume, multi-type battery-powered lighting fixtures. The device includes a charging and discharging platform and a control cabinet. The charging and discharging platform is equipped with an expansion interface to support cascading expansion, while the control cabinet drives relays to automatically execute a complex "four-charge, three-discharge" process. The control cabinet senses the charging current of each branch to prevent overcurrent risks and provides early warnings through distributed temperature sensing and leakage monitoring. The charging and discharging system has multiple preset charging and discharging modes to adapt to the maintenance needs of different battery-powered lighting fixtures. Furthermore, it utilizes 5G communication and cloud monitoring software to achieve remote interaction of maintenance data, and combines QR code image recognition to establish digital maintenance files for battery-powered lighting fixtures, achieving the effects of improved safety, reduced manpower, and lean management.
