Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an intelligent site monitoring module, a power supply system, and a base station. Background Technology

[0002] In the field of power supply guarantee for communication base stations, traditional power supply systems face many technical bottlenecks and are unable to meet the operational needs of modern high-power base stations.

[0003] In terms of energy storage, traditional systems generally employ single-cell or small-scale parallel battery configurations. This approach results in severely insufficient energy storage capacity, with system energy density typically below 200Wh / kg. With the increasing prevalence of high-power base stations, the demand for long-term backup power is rising. The limited energy reserves of traditional systems cannot provide sufficient and sustained power support, severely restricting the stable operation time of base stations under sudden power outages. Regarding battery management, traditional sites rely on independent Battery Management Systems (BMS) for battery management. Due to the lack of a unified scheduling platform, efficient collaboration between battery clusters is difficult. During battery operation, circulating current losses are significant, exceeding 5%. This not only wastes a large amount of energy and reduces the overall efficiency of the battery system but may also affect battery lifespan and system reliability.

[0004] Furthermore, the diversity of communication protocols among devices within the site also poses challenges to system operation. Devices within the site employ various heterogeneous protocols such as CAN and RS485, with differences in data formats and communication rules between these protocols, leading to significant difficulties in data integration. Simultaneously, this heterogeneous protocol environment results in substantial latency during data interaction in the cloud, typically exceeding 500ms. In base station operation scenarios with high real-time requirements, such high latency hinders real-time system decision-making, making it difficult to respond and adjust to the base station's operational status in a timely manner, increasing the risk and uncertainty of base station operation. In summary, the numerous problems existing in traditional power supply systems regarding energy storage, battery collaborative management, and data interaction have become key factors restricting the stable and efficient operation of high-power base stations, urgently requiring solutions through technological innovation.

[0040] Reference Figure 1 , Figure 1 This is a schematic diagram of the first embodiment of the intelligent site monitoring module proposed in this application. Figure 1 This application presents a first embodiment of the intelligent site monitoring module.

[0041] The intelligent site monitoring module includes: a parameter acquisition circuit 100 and a controller 200; the parameter acquisition circuit 100 is connected to the controller 200 and each battery pack 300, the battery packs 300 are connected in parallel, and the controller 200 is also connected to each battery pack 300.

[0042] It should be noted that the intelligent site monitoring module is a key component of the communication base station power supply system, mainly used for intelligent monitoring and management of multiple parallel battery packs 300. This module consists of a parameter acquisition circuit 100 and a controller 200, which work together to achieve efficient control of the battery packs 300.

[0043] It should be noted that a single intelligent site monitoring module can manage up to 32 battery packs connected in parallel. This means that the intelligent site monitoring module can build large-scale energy storage systems. Through precise control algorithms and efficient communication mechanisms, it can monitor and regulate key parameters such as the charging and discharging status, voltage, current, and temperature of each battery pack in real time. On the one hand, the intelligent site monitoring module can balance the workload among the battery packs, avoiding performance degradation caused by overcharging and discharging of some battery packs, effectively extending the lifespan of the entire energy storage system. On the other hand, the parallel scale of 32 battery packs can significantly improve the system's energy storage capacity and output power, providing stable and reliable power support whether applied to peak shaving and frequency regulation in new energy power plants or meeting the backup power needs of large data centers. In addition, the modular management characteristics of the intelligent site monitoring module also support flexible expansion and maintenance of battery packs. Individual battery packs can be added or replaced without affecting the overall system operation, greatly enhancing the adaptability and maintainability of the energy storage system.

[0044] The parameter acquisition circuit 100 is used to acquire the state of charge of each of the battery packs 300.

[0045] It should be understood that the parameter acquisition circuit 100 is responsible for acquiring the state of charge (SOC) of each battery pack 300 in real time and transmitting this data to the controller 200. The state of charge is an important parameter reflecting the remaining battery capacity, and accurately obtaining this information is crucial for the rational scheduling and use of the battery packs 300.

[0046] The controller 200 is used to sort the state of charge of each battery pack 300 and output a drive signal to each battery pack 300 according to the sorting result so that each battery pack 300 discharges.

[0047] It should be noted that the controller 200, as the core of the intelligent site monitoring module, undertakes the tasks of data processing and decision-making. After receiving the state of charge (SOC) data of each battery pack 300 from the parameter acquisition circuit 100, the controller 200 sorts the data. By sorting the SOC data, the controller 200 can clearly understand the power status of each battery pack 300. Based on the sorting results, the controller 200 outputs corresponding drive signals to each battery pack 300. These drive signals control the discharge sequence and discharge power of the battery packs 300, making the discharge process more scientific and reasonable. For example, the controller 200 can prioritize the discharge of battery packs 300 with higher SOC, thereby making full use of the fully charged battery packs 300, extending the overall power supply system's duration, and also helping to balance the usage frequency of each battery pack 300, extending their lifespan.

[0048] It should be understood that through this intelligent monitoring and management approach, the intelligent site monitoring module can effectively solve the problem of low collaborative efficiency of battery packs in traditional power supply systems, improve the stability and reliability of the entire power supply system, and provide strong support for the long-term stable operation of high-power base stations.

[0049] In this embodiment, the intelligent site monitoring module includes a parameter acquisition circuit 100 and a controller 200. The parameter acquisition circuit 100 is connected to the controller 200 and each battery pack 300, which are connected in parallel. The controller 200 is also connected to each battery pack 300. The parameter acquisition circuit 100 is used to acquire the state of charge (SOC) of each battery pack 300. The controller 200 is used to sort the SOC of each battery pack 300 and output drive signals to each battery pack 300 according to the sorting results, so that each battery pack 300 can discharge. This application improves the energy storage capacity by using the parallel use of each battery pack 300 through the intelligent site monitoring module; and improves the collaborative efficiency of the battery packs 300 by uniformly scheduling the battery packs 300, sorting the SOC of each battery pack 300, and outputting drive signals to each battery pack 300 according to the sorting results, so that each battery pack 300 can discharge.

[0050] Reference Figure 2 , Figure 2 This is an electrical schematic diagram of a second embodiment of the intelligent site monitoring module proposed in this application. Based on the first embodiment of the intelligent site monitoring module described above, a second embodiment of the intelligent site monitoring module of this application is proposed.

[0051] The intelligent site monitoring module also includes: a first CAN communication interface CAN1 and a second CAN communication interface CAN2.

[0052] It should be noted that the intelligent site monitoring module includes two key CAN (Controller Area Network) communication interfaces: the first CAN communication interface CAN1 and the second CAN communication interface CAN2. This design enables the module to communicate simultaneously with the battery pack 300 and the external control unit 600, achieving real-time monitoring of the battery pack 300 and interaction with external systems.

[0053] The first CAN communication interface CAN1 is connected to the first end of the first battery pack 300; the second end of the first battery pack 300 is connected to the first end of the second battery pack 300; the second end of the second battery pack 300 is sequentially connected to the first end of the tail battery pack 300; the second end of the tail battery pack 300 is grounded.

[0054] It should be understood that the first CAN communication interface, CAN1, is directly connected to the first terminal of the first battery pack 300. Subsequently, the battery packs 300 are connected in series, meaning the second terminal of the first battery pack 300 is connected to the first terminal of the next battery pack 300, the second terminal of the next battery pack 300 is then connected to the first terminal of the next battery pack 300, and so on, until the last battery pack 300. The second terminal of the last battery pack 300 is grounded, providing an electrical reference point for the entire battery pack 300 system.

[0055] It should be noted that through this connection method, the first CAN communication interface CAN1 can sequentially acquire relevant information from each battery pack 300, starting with the first battery pack 300, such as parameters like voltage, current, and temperature. This data is crucial for monitoring the operating status, performance, and safety of the battery packs 300.

[0056] It should be understood that the series connection allows the battery pack 300 to be managed and controlled as a whole. The intelligent site monitoring module can precisely control the charging and discharging process of the battery pack 300 based on the collected data, ensuring that the battery pack 300 operates within a safe and efficient range. For example, when the voltage of a battery pack 300 is too high or too low, the module can take timely measures to adjust it, preventing overcharging or over-discharging of the battery pack 300, thereby extending its lifespan.

[0057] The second CAN communication interface CAN2 is connected to the external control unit 600.

[0058] It should be noted that the second CAN communication interface, CAN2, is directly connected to the external control unit 600. The external control unit 600 can be the central control system of the entire intelligent site, responsible for coordinating and managing various devices and systems within the site.

[0059] It should be understood that, through the second CAN communication interface CAN2, the intelligent site monitoring module can transmit the collected information from the battery pack 300 to the external control unit 600 in real time. The external control unit 600 can then make optimization decisions regarding energy distribution and equipment operation within the site based on this information. For example, when the battery pack 300 has a low charge, the external control unit 600 can adjust the operating power of other equipment, prioritizing power supply to critical equipment, or activate charging equipment to charge the battery pack 300.

[0060] It should be noted that, with the help of the CAN communication interface, the external control unit 600 can also remotely monitor and control the intelligent site monitoring module. Operators can view the status information of the battery pack 300 in real time on a remote terminal, and set parameters and issue operation commands to the monitoring module, improving the convenience and efficiency of site management.

[0061] The intelligent site monitoring module is also equipped with a LAN port; the LAN port is used to establish a connection between the controller 200 and the cloud system.

[0062] It should be understood that the LAN port equipped in the intelligent site monitoring module is an important physical interface for data interaction between the module and the external network. It breaks the limitations of the module in the local monitoring environment, making it possible for the module to establish connections with a wider range of cloud systems. At the same time, it directly connects to the cloud to reduce cloud interaction latency to <50ms, improving operation and maintenance response speed by 80%. It is a key component for the intelligent site to achieve remote management and intelligent upgrades.

[0063] The intelligent site monitoring module also includes: a first RS485 interface RS4851 and a second RS485 interface RS4852.

[0064] It should be understood that RS485 is a commonly used serial communication interface standard with advantages such as strong anti-interference capability, long transmission distance, and the ability to connect multiple devices. Setting up a first RS485 interface RS4851 and a second RS485 interface RS4852 in the intelligent site monitoring module can meet the communication needs between the module and different external devices, enhancing the system's flexibility and scalability.

[0065] The first RS485 interface RS4851 is connected to an external display 700; the second RS485 interface RS4852 is connected to an external communication device 900.

[0066] It should be noted that the first RS485 interface, RS4851, is connected to the external display 700 via a dedicated RS485 communication cable. The communication cable typically includes two data lines (A line and B line) and possibly a shielding line (to reduce electromagnetic interference) to ensure stable data transmission between the two.

[0067] It should be understood that the intelligent site monitoring module collects various data from the site in real time, such as battery pack status (voltage, current, temperature, etc.), energy consumption, and equipment operating parameters. This data can be transmitted to an external display 700 via the first RS485 interface (RS4851), where it is displayed in intuitive graphical, numerical, or tabular form. On-site personnel can quickly obtain key information about the site without entering the monitoring module or using other complex equipment, facilitating timely understanding of the site's operational status.

[0068] It should be noted that the external monitor 700 provides a simple user interface, allowing staff to perform basic operations on the monitoring module on-site, such as setting display parameters, switching display content, and performing simple device control. This local monitoring method is very useful in emergency situations or when rapid response is required, improving the efficiency and flexibility of site management.

[0069] It should be understood that the same RS485 communication cable is used to connect the second RS485 interface RS4852 to the external communication device 900. During the connection process, it is necessary to ensure that the cable connections are correct, with A wire to A wire and B wire to B wire, to ensure normal communication.

[0070] It should be noted that the data collected by the intelligent site monitoring module can be transmitted to the external communication device 900 via the second RS485 interface (RS4852), and then the external communication device 900 uploads this data to a higher-level management system or cloud platform. In this way, managers from different departments or at different levels can access the site's operational data, achieving data sharing and centralized management. For example, the energy management department can use this data to develop energy plans, and senior management can monitor the overall operation of the site at any time.

[0071] The intelligent site monitoring module is also equipped with a power output unit 800; the power output unit 800 is used to provide a set voltage to external devices.

[0072] It should be noted that the set value can be 24V.

[0073] It should be understood that the power output unit 800 equipped in the intelligent site monitoring module is a crucial functional component of the module, responsible for supplying power to external devices. In an intelligent site system, numerous external devices require a stable power supply to operate normally, such as sensors, actuators, and communication modules. The presence of the power output unit 800 enables the monitoring module to provide these external devices with voltages that meet their operating requirements, ensuring the coordinated and stable operation of the entire intelligent site system.

[0074] It should be noted that the power output unit 800 has a voltage setting function, allowing the output voltage value to be set in several ways. A common method is through the monitoring module's configuration interface or a specific programming interface. For example, technicians can use the accompanying software tool to input the required voltage value according to the specifications of the external device, and then download the setting to the monitoring module. Another method is manual setting via hardware DIP switches, potentiometers, etc. This method is suitable for some simple application scenarios, allowing on-site operators to quickly adjust the output voltage according to actual conditions.

[0075] In this embodiment, the first CAN communication interface CAN1 and the second CAN communication interface CAN2 are connected in series to the battery pack 300, enabling the battery pack 300 to be managed and controlled as a whole. The intelligent site monitoring module can precisely control the charging and discharging process of the battery pack 300 based on the collected data, ensuring that the battery pack 300 operates within a safe and efficient range. Using the CAN communication interface, the external control unit 600 can also remotely monitor and control the intelligent site monitoring module. Operators can view the status information of the battery pack 300 in real time on a remote terminal, and set parameters and issue operation commands to the monitoring module, improving the convenience and efficiency of site management. Through the first RS485 interface RS4851, this data can be transmitted to an external display 700 and displayed in intuitive graphical, numerical, or tabular form. The data collected by the intelligent site monitoring module can be transmitted to the external communication device 900 through the second RS485 interface RS4852, and then the external communication device 900 uploads this data to a higher-level management system or cloud platform. The presence of the power output unit 800 enables the monitoring module to provide these external devices with voltages that meet their operating requirements, ensuring the coordinated and stable operation of the entire intelligent site system.

[0076] Reference Figure 2 Based on the first and second embodiments of the intelligent site monitoring module described above, a third embodiment of the intelligent site monitoring module of this application is proposed.

[0077] The intelligent site monitoring module also includes a fault diagnostic device 400; one side of the fault diagnostic device 400 is connected to the controller 200, and the other side of the fault diagnostic device 400 is connected to the user background monitoring system 500.

[0078] It should be understood that the fault diagnostic device 400 acts as a bridge between the controller 200 and the user background monitoring system 500, facilitating information transmission and processing. On one hand, the fault diagnostic device 400 is closely connected to the controller 200, acquiring various data processed by the controller 200 through specific communication interfaces (such as common serial ports and CAN bus interfaces). This data covers the operational information of the battery pack 300 and its individual cells. On the other hand, it is connected to the user background monitoring system 500, promptly feeding back diagnostic results and important information to the system so that administrators can monitor the operational status of the intelligent site in real time.

[0079] The parameter acquisition circuit 100 is also used to acquire the state of charge of individual cells in each of the battery packs 300, the temperature of each of the battery packs 300, and the discharge current of each of the battery packs 300.

[0080] It should be noted that, in addition to performing conventional parameter acquisition tasks, the parameter acquisition circuit 100 also has the ability to acquire the state of charge (SOC) of individual cells in each battery pack 300, the temperature of each battery pack 300, and the discharge current of each battery pack 300.

[0081] It should be understood that the state of charge (SOC) of a single cell directly reflects the amount of remaining charge in the battery, which is crucial for the balanced management and safe operation of the battery pack 300. The parameter acquisition circuit 100, through high-precision measurement technology, can accurately obtain the SOC value of each single cell, providing basic data for subsequent fault diagnosis.

[0082] It should be noted that the battery pack 300 generates heat during charging and discharging. Excessively high or low temperatures can affect battery performance and lifespan, and may even cause safety issues. The parameter acquisition circuit 100 installs temperature sensors at key locations within the battery pack 300 to monitor temperature changes in real time, ensuring that the battery pack 300 operates within a suitable temperature range.

[0083] It should be understood that the magnitude and stability of the discharge current directly affect the output power and lifespan of the battery pack 300. The parameter acquisition circuit 100 can accurately measure the discharge current of the battery pack 300, promptly detect abnormal current conditions such as overcurrent and short circuit, and provide important information for fault diagnosis.

[0084] The fault diagnostic device 400 is used to issue an alarm command to the user background monitoring system 500 when it detects that the state of charge of each battery pack 300, the state of charge of the individual cells in each battery pack 300, the temperature of each battery pack 300, and the discharge current of each battery pack 300 are not within the corresponding set range.

[0085] It is important to understand that the fault diagnostic device 400 receives real-time operating data of the battery pack 300 and its individual cells from the parameter acquisition circuit 100, including state of charge, temperature, and discharge current. It compares and analyzes these actual measurements with pre-set safety ranges. These ranges are determined based on factors such as battery specifications, performance, and the operational requirements of the smart station, aiming to ensure that the battery pack 300 operates under safe and efficient conditions.

[0086] It should be understood that when the fault diagnostic device 400 detects that the state of charge (SOC) of each battery pack 300, the SOC of individual cells within each battery pack 300, the temperature of each battery pack 300, and the discharge current of each battery pack 300 are not within the corresponding set range, it will immediately determine that there is a fault or abnormality in the system. At this time, the fault diagnostic device 400 will quickly issue an alarm command to the user's backend monitoring system 500. The alarm command typically includes detailed information such as the fault type, the time of the fault occurrence, and the actual measured values ​​of relevant parameters, so that the backend administrators can quickly understand the fault situation and take appropriate measures to handle it.

[0089] The intelligent site monitoring module also includes a DI interface (DI) and a DO interface (DO); the DI interface (DI) and the DO interface (DO) are respectively connected to the user background monitoring system 500.

[0090] It should be noted that the DI and DO interfaces are connected to the user's backend monitoring system 500 via specific communication lines (such as cables). During the connection process, it is necessary to ensure the electrical characteristics of the interfaces are compatible, such as voltage level and signal polarity. Typically, standard communication protocols (such as Modbus) are used to achieve data transmission and interaction between the interfaces and the backend monitoring system to ensure the accuracy and reliability of data transmission. Through the connection of the DI and DO interfaces to the user's backend monitoring system 500, administrators can remotely monitor the operational status of the intelligent site in real time and remotely control external devices. Most monitoring and operation tasks can be completed without on-site presence, improving management efficiency and reducing labor costs.

[0091] Users can remotely operate each of the battery packs 300 through the background monitoring system according to the alarm command.

[0092] It should be understood that the remote operation of each battery pack 300 by the user through the background monitoring system based on alarm commands is a complete process involving multiple stages, including alarm triggering, interface operation, decision-making, security assurance, and effect feedback. Through this process, users can handle abnormal situations of the battery pack 300 in a timely and effective manner, improving the operational reliability and security of the intelligent site.

[0093] In this embodiment, the fault diagnostic unit 400 in the intelligent site monitoring module, through its connection with the controller 200 and the user background monitoring system 500, combined with key data collected by the parameter acquisition circuit 100, achieves real-time monitoring and fault diagnosis of the battery pack 300 and its individual cells, providing strong support for the safe and stable operation of the intelligent site. The DI and DO interfaces in the intelligent site monitoring module, through their connection with the user background monitoring system 500, enable the collection of external status information and remote control functions for the intelligent site. This is of great significance for improving management efficiency, enhancing system security, realizing intelligent management, and facilitating fault diagnosis and maintenance.
