Description

Technical Field

[0001] This invention relates to the field of information processing, and particularly to an emergency fire-fighting system for a battery compartment. Background Technology

[0002] Battery storage safety has always been a major concern in energy storage systems, as its safety is crucial for the overall operation. Due to the design and chemical characteristics of lithium batteries, they are inherently prone to thermal runaway, which can be extremely difficult to extinguish once it occurs. For fire management, in addition to improving the safety of the batteries themselves, it is essential to monitor the thermal state of the batteries during use through monitoring systems. This allows for early detection of thermal runaway, preventing potential fires in their early stages. Furthermore, it is crucial to be able to promptly transmit relevant data through emergency systems in the event of thermal runaway or abnormal temperatures. Therefore, in the emergency management of battery storage facilities, integrating information from the battery storage facility with fire control measures to ensure the safe operation of the energy storage system and the safety of users and those in the surrounding area is a critical issue that needs to be addressed. Current technologies lack the ability to accurately detect, provide early warnings, and efficiently manage the batteries within the energy storage system. Summary of the Invention

[0003] Based on the above problems, this invention proposes an emergency fire protection system for battery compartment management.

[0004] The system includes: a safety monitoring device, an anomaly warning device, a user terminal, a gateway, and a remote server. Different sensors are installed in the battery compartment to monitor the status data of the batteries in the battery compartment. Different safety monitoring devices and anomaly warning devices form a short-range communication network with the gateway device. The gateway device to which the battery compartment belongs in different locations communicates with the remote server. The user terminal accesses the remote server to obtain early warning management information. The safety monitoring device collects battery status information from the battery compartment in real time. Based on the battery data in the battery compartment, the safety monitoring device performs different clustering processes on different battery information, divides them into different theme categories, and sets alarm thresholds for early warning information under different theme categories. The anomaly warning device is used to make anomaly judgments based on the real-time collected battery compartment status data. The anomaly judgment is specifically as follows: when the alarm information under different theme types of the safety monitoring device exceeds the set value, an alarm information is sent to the remote server. The alarm information is sent to the remote server through the home gateway via different paths according to different levels; the alarm information includes at least the battery compartment ID information and monitoring clock information.

[0005] Preferably, the specific monitoring parameters of the safety monitoring device include at least: battery cell temperature, battery cell deformation, battery cell pressure, battery cell leakage, battery compartment explosive gas, battery compartment ambient temperature, and battery compartment smoke.

[0006] Preferably, the basic data of the battery specifically includes: battery nameplate information and historical operating data of the batteries in the battery compartment under different battery nameplate attributes.

[0007] Preferably, the data collected in real time by the safety monitoring device also includes: battery cluster information, battery box information, and battery voltage.

[0008] Preferably, the security monitoring device receives dynamic monitoring commands from a remote server, specifically setting different monitoring tasks based on information crawled from news and web pages. Optionally, a web crawler is used to crawl news media data within web pages, with different monitoring tasks assigned.

[0009] Preferably, the remote server triggers different alarm linkage mechanisms for different early warning information and pushes processing rules to the management user interface. The pushed processing rules display different situation simulation early warnings according to different early warning information types, providing processing measures for the management user interface.

[0010] Preferably, the system further includes setting up relay gateways within the area according to different locations of the battery compartment, with different relay gateway units forming an information transmission network, and the topology diagram of the relay gateways being stored in a remote server.

[0011] Preferably, the linkage processing of alarm information further includes, during the initial configuration phase, configuring different relay gateways based on the physical coordinates of different battery compartments. The relay gateway can be a centralized equipment gateway in a fire communication system; optionally, the centralized equipment gateway can be a dedicated fire equipment network access device located within the community. Optionally, monitoring devices in different battery compartments are controlled through relay gateways.

[0012] Preferably, the remote server obtains the location information map of the battery compartments in the region based on the geographical location information, configures the relay gateway access topology map according to the information of the home gateway, configures redundant virtual relay gateways for different battery compartment fire information, and sets different sending paths to send the warning information according to different warning type levels.

[0013] Preferably, the remote server also includes monitoring the status information of different relay gateway devices, obtaining the coverage information of the relay gateway devices, and when the coverage information is not within a preset range, configuring the relay gateway to adjust the short-range relay strategy according to the current status information.

[0014] The relay strategy includes: determining whether the coverage of the relay gateway is within a preset threshold range; if so, setting the rate of monitoring information upload and the relay duration based on the current coverage information.

[0015] This invention discloses a battery compartment emergency fire protection system. In this system, different abnormal warning thresholds are set for different theme types. The different abnormal warning thresholds are based on monitoring by multiple different sensors. Different themes are divided according to battery-related historical data information. There is cross information between the themes. The alarm information is finally determined by the number of abnormal warnings. According to the alarm information level, multi-path relay transmission and deduplication settings are performed through the gateway in the area to ensure system safety redundancy and timely transmission of alarm messages.

Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0022] Example 1 like Figure 1 As shown, this invention proposes a fire-fighting battery compartment management emergency system. The system includes: a safety monitoring device, an anomaly warning device, a user terminal, a battery compartment, a gateway, and a remote server. Different sensors are installed in the battery compartment to monitor the status data of the batteries. The different safety monitoring devices and anomaly warning devices form a short-range communication network with the gateway device. The gateway device to which each battery compartment belongs communicates with the remote server. The user terminal accesses the remote server to obtain early warning management information.

[0023] The safety monitoring device collects battery status information in the battery compartment in real time. Based on the basic data of the battery, the safety monitoring device extracts and sets early warning information. The preprocessed data under different clustering themes may overlap or intersect.

[0024] The basic data for the battery can be based on the battery nameplate information combined with historical operating data. Different battery information is categorized and processed according to different themes, optionally using the k-means algorithm. Historical data includes battery failure time, leakage, automatic overcharge failure, etc. Different battery information categories include battery type information, such as chemical composition (e.g., lithium battery, lithium phosphate battery). Text or data information is acquired, and cluster analysis is performed on different themes to extract battery safety operating status data under different theme types. Based on this, warning thresholds or feature vectors are set.

[0025] The real-time information acquisition includes cluster processing for different batteries to obtain real-time data such as battery cluster information, battery box information, alarms, battery voltage and temperature. The data information is sent incrementally to the home gateway. The home gateway can be configured with a display unit to display the acquired information. On the local device, the local device can optionally be a single-node single-screen display.

[0026] For the same battery compartment, an anomaly warning device is also configured. This device receives battery compartment data uploaded by the safety monitoring device, matches the real-time collected battery compartment status data with the battery compartment data feature values, and determines whether an anomaly exists. If the number of anomalies exceeds a preset value, different types of alarm information are sent through the home gateway. The anomaly warning information is based on thresholds set under different classification themes, and different alarm information is set based on different thresholds.

[0027] In this exemplary approach, monitoring alarms for the same battery compartment are abnormal warnings for different types of topics. When the abnormal warning information for different types exceeds the set value, an alarm message is sent to the remote server to reduce the generation of false alarms. The set value can be configured based on historical operating data to set the parameter range for the battery compartment, battery cluster, and battery box.

[0028] The safety monitoring device further includes a function for statistical analysis of historical battery data, analyzing and displaying the battery data storage records based on the historical statistical data, and performing data processing. The specific monitoring parameters of the safety monitoring device may include: battery cell temperature, battery cell deformation, battery cell pressure, battery cell leakage, explosive gas in the battery compartment, ambient temperature in the battery compartment, and smoke in the battery compartment.

[0029] For example: The detection of the battery cell temperature includes setting up a temperature sensing and monitoring unit and / or a resistivity tomography unit and its corresponding sensing and transmitting device within the battery cell, for obtaining real-time temperature information of the battery cell and transmitting the obtained information to the gateway unit of the battery compartment or to a remote server.

[0030] The battery cell deformation monitoring includes a deformation sensing and monitoring device inside the battery cell and / or a variable resistance monitoring unit on the surface of the battery cell and its corresponding sensing and transmitting unit, used to acquire real-time deformation information of the battery cell and transmit the acquired information to the remote server of the battery compartment gateway unit.

[0031] For example, the battery cell pressure monitoring also includes the monitoring of explosive gases in the battery compartment, specifically one or more of the following: CO explosion gas detection, H2 explosion gas detection, CH4 explosion gas detection, VOC volatile matter detection, etc., and their corresponding sensing and transmitting devices. The composition and real-time concentration information of the explosive gases in the battery compartment are acquired, and the acquired information is transmitted to the battery compartment gateway to a remote server.

[0032] The safety monitoring device supports dynamic configuration. In a preferred embodiment, the device receives dynamic monitoring commands from a remote server. These commands specifically set different monitoring tasks based on information crawled from news articles and web pages. In a specific implementation, a web crawler is used to crawl news media data and historical fire data from web pages, setting different monitoring tasks. Optionally, during winter, the correlation between fire types and lithium batteries can be extracted, and an overcharge leakage monitoring task can be set for the battery compartment. The remote server dynamically acquires the crawled information in real time and issues monitoring tasks, configuring different priorities for different detection data to ensure the processing efficiency of the safety monitoring device.

[0033] In a specific implementation, real-time monitoring is performed on battery cell temperature, battery cell deformation, battery cell pressure, leakage, explosive gas concentration in the battery compartment, ambient temperature in the battery compartment, and smoke conditions in the battery compartment. An anomaly alarm device determines when monitoring results exceed set thresholds or when leakage occurs, issuing an anomaly warning. When the anomaly warning exceeds a set value, a fault is identified, a matching alarm linkage mechanism is obtained, and different fire-fighting linkage mechanisms are triggered. Simultaneously, the remote server pushes processing rules to the management user interface. These pushed rules display different scenario simulation warnings based on different warning information, providing management users with appropriate response measures.

[0034] For determining fault information in alarm messages, for example, a local battery fault link topology graph containing instantaneous fault nodes can be constructed based on the battery state relationship chain information. The fault chains collected by the distributed link tracing tool represent the basic information of the association between different battery states. A local microservice link topology graph can also be constructed, where nodes represent a certain state of the battery and edges represent the jump relationship between battery states. Based on the fault link topology graph, a dynamic fault responsibility score is calculated for different battery states to determine the battery state of the instantaneous fault root cause. The fault responsibility score refers to the degree of fault responsibility correlation of each battery state node in the local battery link topology graph, and the fault responsibility score includes anomaly correlation score, performance correlation score, and causal correlation score.

[0035] For example, the anomaly correlation score is used to measure the amount of anomaly information contained in each battery state. Based on the local battery fault link topology, batteries that are closer to the instantaneous fault node contain more anomaly-related information, and therefore have higher anomaly correlation scores. Based on the weighted score of the monitored parameter information, the root cause of the fault and the faulty battery are determined, and corresponding fire-fighting measures are provided according to the root cause. Optional measures include, when it is determined that the battery module is experiencing thermal runaway or a serious fault, the corresponding measure could be to directly trigger a relay within the module to isolate the faulty object. When it is determined that the system is experiencing an emergency fault, a linkage mechanism can be activated. This linkage mechanism specifically configures the fire protection system, the energy storage converter in the battery compartment, and the energy management system of the battery compartment to work together. When the system experiences or receives an emergency fault, the direct protection mechanism will cut off the power input and output of the battery compartment system.

[0036] For example, the abnormal alarm unit triggers alarm information according to different levels. When a medium- or low-risk alarm is triggered, it sends a warning message to the remote management unit and simultaneously issues a local alarm audible or visual prompt via the alarm notification unit. When a high-risk alarm is triggered, it automatically activates the explosion suppression device and sends a warning message to the remote server, while simultaneously issuing a local alarm audible or visual prompt via the alarm notification unit.

[0037] The alarm information is stored and forwarded through the home gateway unit of the battery compartment. According to the regional location information, relay gateways are configured for the home gateways of different battery compartments. The different relay gateway units form an information transmission network. The topology diagram of the relay gateways is stored in a remote server. Different battery compartments are configured with a primary home gateway and a secondary home gateway. The secondary home gateway can be a virtual home gateway as a redundancy backup configuration.

[0038] In the optional approach, different alarm types are configured with different relay gateway information transmission paths. Optionally, different transmission paths are configured for different warning messages, and the matching transmission paths are adapted to the intensity of the warning message. The warning message also includes at least initial clock information and battery compartment identification information, which are used by the remote server to perform deduplication upon receiving the warning message.

[0039] In a specific implementation, the linkage processing of alarm information further includes, during the initial configuration phase, the remote server configuring different home gateways based on the physical coordinates of the areas described in the different battery compartments. Optionally, different battery compartments are configured to different home gateways. Home gateways with adjacent physical coordinate information are configured with the same relay gateway, which can be a centralized equipment gateway in a fire communication system. Optionally, the centralized equipment gateway can be a fire equipment private network access network device located within the community. Optionally, different battery compartment devices are controlled through their home gateways.

[0040] In a preferred embodiment, the remote server obtains a location map of the battery compartments within the region based on geographical location information. It configures the network access topology according to the assigned relay gateway. To ensure that monitoring and alarm information from the battery compartments can be transmitted to the remote server, redundant virtual home gateways are configured for different battery compartment fire alarm information. The virtual home gateway topology map is then sent to the actually controlled relay gateway device. Different transmission paths are set according to different alarm types for sending alarm information. It is known that the home gateway and relay gateway can be the same device. For different location areas, the same home gateway can be a relay gateway for a battery compartment at a different location.

[0041] In an exemplary embodiment, the relay gateway in the battery compartment station has two power supply options: self-contained power and external power supply. Depending on the location of the battery compartment station, when the relay gateway is configured with self-contained power, it configures different short-range communication power modes based on its own power information and alarm scenarios to improve the accuracy of relay function control.

[0042] For example, the remote server also includes monitoring the status information of different relay gateway devices, obtaining the coverage information of the relay gateway devices, and when the coverage information is not within a preset range, configuring the remote server to adjust the short-range relay strategy of the relay gateway according to the current status information.

[0043] The relay strategy includes: determining whether the coverage of the relay gateway is within a preset threshold range; if so, setting the monitoring information upload rate and relay duration based on the current coverage information; if not, waking up the configuration information of other gateways associated with the relay gateway in the gateway topology diagram via a remote server, and sending the set relevant relay information, including: the power and operating mode of the relay gateway. For example, user terminals are distinguished into management terminals and user terminals, with different user terminals having different permission information, and different permission information being set to receive different alarm information. For example, different alarm information types are pushed according to different management permission levels.

[0044] In a specific implementation, a safety monitoring device is included, and further may include a safety control strategy unit. For different battery compartments, based on different monitoring information, different safety levels are determined by identifying thresholds for different runaway states and / or safety states. According to pre-set safety rule data, different information is set with different parameters corresponding to different faults.
