[0020] Example 1

[0021] Reference Figure 1 to Figure 3 , is the first embodiment of the present invention, which provides a battery remote nuclear capacity safety protection device, which includes a monitoring host, a monitoring terminal, and a battery acquisition module. The battery acquisition module is connected to the monitoring terminal through a 485 communication interface. The battery acquisition module comprehensively acquires data such as voltage, current, internal resistance, temperature, etc. of the battery pack and single battery, and transmits the signal of the collected information. The monitoring terminal is connected to the battery acquisition module through a 485 communication interface. The monitoring terminal receives multiple types of information signals from the battery acquisition module, and makes monitoring decisions based on the information of the signal. The monitoring host is connected to the monitoring terminal through a 485 communication interface, and the monitoring host remotely controls and operates the data of the monitoring terminal.

[0022] The invention mainly solves the technical problems of low efficiency and high safety risk of manual on-site operation in the existing battery capacity verification and maintenance. Traditional capacity verification operation requires manual monitoring and control by on-site personnel, which is not only inefficient but also has the risk of operational errors. The present invention realizes remote automatic monitoring of the battery capacity verification process by setting up a three-level architecture of a monitoring host, a monitoring terminal and a battery acquisition module. The battery acquisition module is connected to the monitoring terminal through a 485 communication interface to comprehensively collect data such as the voltage, current, internal resistance, and temperature of the battery pack and a single battery; the monitoring terminal receives these information signals and performs monitoring and judgment; the monitoring host is connected to the monitoring terminal through a 485 communication interface to realize remote control and operation of the monitoring terminal data. This hierarchical system architecture eliminates the safety hazards of manual on-site operation, improves the efficiency of capacity verification and maintenance, and at the same time ensures the safety and reliability of the capacity verification process through a multi-level data collection and monitoring mechanism. Compared with the traditional manual operation method, the device realizes remote automation of battery capacity verification and maintenance, greatly reducing labor costs and operational risks.

[0023] Furthermore, the monitoring host and the monitoring terminal are respectively connected to the shunt through signal lines, and the monitoring terminal is connected to the bus voltage sampling module through the signal line.

[0024] The technical problems of poor accuracy and lack of real-time performance of current and voltage sampling in existing battery capacity-reducing devices are solved. By connecting the monitoring host and the monitoring terminal to the shunt respectively, and connecting the monitoring terminal to the bus voltage sampling module, high-precision real-time sampling of the battery pack charging and discharging current and bus voltage is achieved. This solution overcomes the technical defects of traditional sampling methods such as large measurement errors and delayed response, improves the accuracy and real-time performance of data acquisition, and provides reliable data support for the safety monitoring of the capacity-reducing process.

[0025] Furthermore, the background monitoring system mainly includes a data service end, a management end and a database.

[0026] The solution solves the technical problems of the lack of systematic background support and decentralized data management in existing battery capacity-reducing devices. By setting up a three-tier architecture of data service end, management end and database, the integration of data collection, processing, storage and management is achieved. The solution overcomes the defects of the single structure and functional separation of the background system of traditional capacity-reducing devices, establishes a complete data processing flow, and provides a unified platform support for data analysis and decision-making in the capacity-reducing process.

[0027] Furthermore, the server mainly provides behavioral support for on-site data collection and monitoring, performs precision processing on the data obtained on-site and reports it to the database, using a distributed layout.

[0028] The technical problems of low accuracy of on-site data processing and untimely data reporting in existing battery capacity verification devices are solved. By adopting a distributed server architecture, behavioral support is provided for on-site data collection and monitoring, and the data obtained on-site is accurately processed and reported to the database. This solution overcomes the problems of response delay and limited processing capacity caused by centralized data processing in traditional systems, improves the accuracy and real-time performance of data processing, and ensures accurate acquisition and timely reporting of on-site data during the verification process.

[0029] Furthermore, the management end uses the B / S network architecture as the basis to realize multi-endpoint communication with the user end. It is mainly responsible for business query, reporting, management, data analysis, real-time decision-making or adjustment, etc., and adopts a distributed layout.

[0030] The technical problems of inconvenient user interaction and limited business processing capabilities in existing battery capacity evaluation devices are solved. By adopting a distributed management terminal design based on the B / S network architecture, multi-endpoint communication on the user side is realized to complete business query, reporting, management, data analysis and real-time decision-making functions. This solution overcomes the defects of limited user access and low business processing efficiency of traditional systems, provides flexible user access methods and comprehensive business processing capabilities, and enhances the remote management and decision-making efficiency of the capacity evaluation process.

[0031] Furthermore, the database serves as the central area, responsible for the storage and management of historical data and real-time data, as well as the storage of key information such as user information and system configuration.

[0032] The technical problems of scattered data storage and chaotic system information management in existing battery capacity evaluation devices are solved. By setting the database as a central area, it is responsible for the storage and management of historical data, real-time data, and key information such as user information and system configuration. This solution overcomes the defects of fragmented data storage and inconsistent information management in traditional systems, realizes centralized management of data and system information, and provides reliable information support for data traceability and system maintenance in the capacity evaluation process.

[0033] Furthermore, the battery acquisition module includes a signal holding unit, a sampling isolation unit, an AD sampling unit, a main processor MCU, and a communication interface. The signal holding unit, sampling isolation unit, AD sampling unit, main processor MCU, and communication interface are connected in sequence through signal lines. After the battery acquisition module obtains real-time signals through each signal holding unit, the sampling isolation unit transmits it to the AD sampling unit to complete quantization processing, and then after the main processor MCU completes information confirmation, it reports to the terminal through the 485 communication interface.

[0034] The technical problems of low data acquisition accuracy and poor anti-interference ability in existing battery capacity verification devices are solved. By setting up a series structure of a signal holding unit, a sampling isolation unit, an AD sampling unit, a main processor MCU and a communication interface, a complete processing flow from signal acquisition to data reporting is realized. The sampling isolation unit effectively isolates the interference signal, the AD sampling unit realizes the accurate quantization of the analog signal, and the MCU confirms and processes the information and reports it to the terminal through the 485 communication interface. This solution overcomes the defects of poor anti-interference and low data quantization accuracy of traditional acquisition modules. Through the orderly cooperation of various functional units, the accuracy and reliability of the collected data are ensured, and the quality of battery parameter collection during the capacity verification process is improved.

[0035] In summary, the battery remote nuclear capacity safety protection device of the present invention is mainly composed of a monitoring host, a monitoring terminal, and a battery acquisition module, which comprehensively monitors the voltage, current, internal resistance, temperature, etc. of the battery pack and a single battery, completes the background information feedback and alarm decision information transmission, adopts the power LAN technology to set up a communication network, connects with the battery online monitoring device, establishes a high-efficiency comprehensive network system for data acquisition, transmission, and analysis, equips a single battery with an independent monitoring host, completes the host connection through Ethernet and a switch, and the background client can be directly connected to any host through the network for adjustment. And it has the advantages of simple structure, safety and effectiveness, and good use effect.
