Description

Technical Field

[0001] The present invention relates to the technical field of circuit breaker fault monitoring, and in particular to a distributed wireless circuit breaker temperature monitoring system. Background Art

[0002] At present, the traditional diagnostic method for circuit breaker overheating failure mainly relies on the substation operation and maintenance personnel to personally conduct on-site inspections of the equipment. During this process, they usually use handheld infrared thermal imaging instruments to measure and record the temperature status of related equipment. However, this traditional method has exposed several significant shortcomings in practice:

[0003] (1) Due to the time constraints of regular inspections by operation and maintenance personnel, this method cannot achieve all-weather, uninterrupted monitoring coverage, making it difficult to capture and respond immediately to sudden, unexpected equipment overheating problems, which undoubtedly increases the risk of fault escalation and even causing larger-scale power accidents.

[0004] (2) When performing inspection tasks, operation and maintenance personnel have to come into close contact with high-voltage equipment that is still energized. This operating environment itself contains extremely high safety risks. Not only may personal injury be caused by misoperation or sudden equipment failure, but it may also cause serious accidents such as short circuits due to insufficient electrical insulation, further threatening the stable operation of the power system and the safety of personnel.

[0055] Embodiment 1

[0056] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in this field, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art. After continuous research and design, and after repeated trial production and improvement, the present invention with real practical value was finally created.

[0057] Please refer to Figure 1-4 The embodiment of the present invention provides a distributed wireless circuit breaker temperature monitoring system, the system comprising a temperature acquisition node 1, a data processing and transmission node 2 and a remote monitoring center 3; wherein,

[0058] The temperature acquisition node 1 and the remote monitoring center 3 are respectively connected to the data processing and transmission node 2 through a wireless network to establish communication. This design ensures the flexibility of data transmission and the scalability of the system;

[0059] The temperature acquisition node 1 is used to collect the temperature data of the circuit breaker by automatic acquisition, and send the collected temperature data and its own device number to the data processing and transmission node 2; this step not only improves the accuracy of data acquisition, but also enhances the traceability of the data source;

[0060] The data processing and transmission node 2 is used to process the temperature data and the device number through distributed processing technology after receiving them, and transmit them to the remote monitoring center 3; after efficient processing, the data processing and transmission node 2 will further transmit the data to the remote monitoring center 3 for subsequent analysis;

[0061] The remote monitoring center 3 is used to analyze and count the processed data through distributed computing technology after receiving it; by adopting distributed computing technology, the center can conduct in-depth analysis and statistics on these data, thereby realizing comprehensive monitoring of the circuit breaker temperature. This process not only improves the accuracy and efficiency of data analysis, but also provides a strong guarantee for the stable operation of the power system.

[0062] It should be noted that the implementation example of the present invention successfully realizes remote, real-time and efficient fault monitoring of circuit breaker temperature by introducing automatic temperature measurement technology and combining distributed processing, analysis and statistical methods. This innovation not only significantly reduces the investment cost of human resources, but also effectively ensures the safety of operation and maintenance personnel. In the long run, the application of this system will be conducive to building a safer, more reliable and efficient power system operation and maintenance system, and contribute to the sustainable development of the power industry.

[0063] Please refer again Figure 2 , in one implementation of this embodiment, the temperature acquisition node 1 includes a number of wireless temperature sensors 11;

[0064] A plurality of the wireless temperature sensors 11 are connected via a wireless network to form a wireless temperature sensor network.

[0065] Specifically, each wireless temperature sensor 11 has independent data collection and transmission capabilities, and they are interconnected through advanced wireless network technology to form a sensor network with wide coverage and rapid response. This design not only improves the density and accuracy of data collection, but also significantly enhances the flexibility and reliability of the system.

[0066] In this wireless temperature sensor network, each sensor can work together to complete the real-time monitoring of the circuit breaker temperature. When a sensor detects an abnormal temperature, it can quickly transmit this information through the wireless network to the data processing and transmission node 2 for subsequent processing and analysis.

[0067] In this way, the implementation example of the present invention not only realizes remote and real-time monitoring of the circuit breaker temperature, but also significantly improves the accuracy and timeliness of fault detection. This innovative design not only reduces the operation and maintenance costs, but also further ensures the stable operation of the power system, providing strong support for the intelligent development of the power industry.

[0068] Please refer again Figure 3 In one implementation of this embodiment, the data processing and transmission node 2 includes a coordinator 21 and a plurality of processing nodes 22;

[0069] As the core component of the data processing and transmission node 2, the coordinator 21 bears the important responsibility of data reception and distribution. When the coordinator 21 receives the temperature data and device number from the temperature acquisition node 1, it will immediately distribute the data to several processing nodes 22 for parallel processing according to the preset allocation strategy. This design not only significantly improves the speed and efficiency of data processing, but also enhances the scalability and fault tolerance of the system.

[0070] As an important part of the data processing and transmission node 2, the processing node 22 is responsible for executing specific data processing tasks. After receiving the data distributed by the coordinator 21, each processing node 22 will immediately start its built-in data processing algorithm to process the received data. After the processing is completed, these nodes will transmit the processed data to the remote monitoring center 3 in parallel for subsequent analysis and statistical use.

[0071] In this way, the implementation example of the present invention not only realizes the fast and efficient processing of circuit breaker temperature data, but also significantly improves the overall performance and reliability of the system. This innovative design not only reduces the operation and maintenance costs, but also further improves the intelligence level of the power system, injecting new vitality into the sustainable development of the power industry.

[0072] Exemplarily, the processing node 22 includes a single chip microcomputer.

[0073] In another specific implementation of this embodiment, the functions of the remote monitoring center 3 are further expanded and optimized. In addition to taking on the tasks of data reception, analysis and statistics, the remote monitoring center 3 also innovatively adopts a distributed storage architecture to achieve efficient storage and management of received data.

[0074] Specifically, when the remote monitoring center 3 receives the processed data from the data processing and transmission node 2, it will intelligently store it in different tables of the database according to factors such as the type, source and importance of the data. This design not only improves the flexibility and scalability of data storage, but also ensures the security and integrity of the data.

[0075] By adopting a distributed storage architecture, the remote monitoring center 3 can achieve fast reading and writing and efficient management of massive data. This not only provides strong support for real-time monitoring and fault warning of the power system, but also provides a rich data source for subsequent data analysis and decision-making.

[0076] In addition, the application of distributed storage architecture further enhances the fault tolerance and reliability of the remote monitoring center 3. Even if a storage node fails, other nodes can quickly take over its tasks to ensure data continuity and availability. This innovative design not only improves the overall performance of the system, but also provides a more solid guarantee for the intelligent development of the power industry.

[0077] Please refer to Figure 5 The specific implementation method of the process of the remote monitoring center 3 accessing the database in the implementation example of the present invention is now described in detail as follows:

[0078] The remote monitoring center loads a driver program of the database interface;

[0079] The remote monitoring center obtains a connector to establish a connection with a database;

[0080] The remote monitoring center obtains the SQL execution program;

[0081] The remote monitoring center sends SQL statements to the database through the SQL execution program to trigger the database to execute corresponding operations according to the SQL statements and return the operation results.

[0082] It should be noted that when the remote monitoring center 3 needs to access the database to perform operations such as data query, insertion, update or deletion, it will follow a series of carefully designed steps to ensure the efficiency and security of data access.

[0083] First, the remote monitoring center 3 loads the driver of the database interface. This step is the basis of data access, which ensures that the remote monitoring center 3 can communicate with the database. The driver usually contains all the information required to interact with a specific database, including the location of the database, port number, authentication information, etc.

[0084] Next, the remote monitoring center 3 will obtain a Connector object. This connector acts as a bridge between the remote monitoring center 3 and the database, and is responsible for establishing and maintaining the connection between the two. Through the connector, the remote monitoring center 3 can send requests to the database and receive responses from the database.

[0085] Then, the remote monitoring center 3 will obtain a SQL Executor object. This object is responsible for parsing and executing SQL statements. The remote monitoring center 3 will pass the SQL statement to be executed to the SQL Executor, which will convert it into a format that the database can understand and send it to the database for execution.

[0086] Finally, the remote monitoring center 3 sends the SQL statement to the database through the SQL execution program. The database will perform corresponding operations according to the received SQL statement, such as querying data, inserting new records, updating existing records or deleting records. After the operation is completed, the database will return the operation result to the remote monitoring center 3. This result may include information such as the queried data, the number of rows affected by the operation, and whether the operation is successfully executed.

[0087] Through this series of steps, the remote monitoring center 3 can access the database safely and efficiently, and realize operations such as query, insert, update and delete of data. This design not only improves the flexibility and reliability of data access, but also provides strong support for real-time monitoring and fault warning of power systems.

[0088] In another innovative implementation of this example, the functions of the remote monitoring center 3 are further expanded, which can not only perform in-depth analysis and statistics on the received data, but also send the processed data back to the data processing and transmission node 2 in parallel, thus forming a closed-loop feedback mechanism.

[0089] Specifically, after completing the data analysis and statistics tasks, the remote monitoring center 3 will use advanced parallel communication technology to quickly and accurately send these valuable data information back to the data processing and transmission node 2. This step not only realizes the two-way flow of data, but also enhances the interactivity and response speed of the system.

[0090] After receiving the analysis and statistical data from the remote monitoring center 3, the data processing and transmission node 2 will immediately start its built-in safety judgment mechanism. This mechanism will strictly compare and analyze the received data according to the pre-set safety threshold. If the data exceeds the safety threshold, it indicates that there may be potential failures or abnormalities in the power system. At this time, the data processing and transmission node 2 will immediately trigger the alarm processing process.

[0091] The alarm handling process may include sending alarm information to operation and maintenance personnel, recording abnormal data in the log system, starting the emergency backup mechanism, etc. This series of response measures is aimed at quickly responding to abnormal conditions in the power system and preventing the fault from further expanding, thereby ensuring the safe and stable operation of the power system.

[0092] Through this innovative design, the implementation example of the present invention not only realizes remote, real-time and efficient monitoring of circuit breaker temperature data, but also further improves the system's fault warning and emergency response capabilities. This design not only reduces operation and maintenance costs, but also significantly improves the intelligence level and reliability of the power system, injecting new impetus into the sustainable development of the power industry.

[0093] Please refer again Figure 4In one implementation of this embodiment, the remote monitoring center 3 includes a computer 31 and monitoring software 32;

[0094] The monitoring software 32 runs in the computer 31 .

[0095] It should be noted that the computer 31, as the hardware foundation of the remote monitoring center 3, provides powerful computing capabilities and a stable operating environment. It is equipped with an advanced processor, a large-capacity memory and a high-speed storage device, ensuring that the monitoring software 32 can run efficiently and stably.

[0096] The monitoring software 32 is the soul of the remote monitoring center 3, which is responsible for performing a series of key tasks such as data reception, analysis, statistics, and alarm. The monitoring software 32 uses advanced algorithms and technologies to process the circuit breaker temperature data from the data processing and transmission node 2 in real time and generate intuitive and easy-to-understand monitoring reports and charts.

[0097] The monitoring software 32 not only provides a user-friendly interface, allowing operation and maintenance personnel to easily view the operating status and abnormal information of the power system, but also has powerful data analysis and early warning functions. By comparing historical data with real-time data, the monitoring software 32 can promptly detect potential faults in the power system and send alarm information to the operation and maintenance personnel, thereby ensuring the safe and stable operation of the power system.

[0098] In addition, the monitoring software 32 also supports remote access and configuration functions, allowing operation and maintenance personnel to monitor and manage the power system at any time and any place. This design not only improves operation and maintenance efficiency, but also reduces operation and maintenance costs, providing strong support for the intelligent development of the power industry.

[0099] To sum up, by combining the computer 31 and the monitoring software 32, the remote monitoring center 3 in the implementation example of the present invention not only has powerful data processing and monitoring capabilities, but also provides flexible and convenient operation and maintenance management functions, providing a solid guarantee for the safe and stable operation of the power system.

[0100] In further refinement of this implementation example, the monitoring software 32 is designed as a comprehensive and highly modular system, specifically including a user login module, a permission module, a query monitoring module and an operation management module to meet the needs of different user groups and ensure the security and efficiency of the system.

[0101] User login module: This module is the entrance for users to access the monitoring software 32. It requires users to enter their username and password and compare them with the user information in the system to verify the user's identity. Only verified users can enter the monitoring system, thus ensuring the security of the system and the confidentiality of data.

[0102] Permission module: The permission module assigns different access and operation permissions based on the user's role and level. This means that different users can access different data ranges and perform different operations. For example, senior operation and maintenance personnel may have the permission to view all monitoring data and perform all operations, while ordinary users may only be able to view part of the data and perform limited operations. This design helps maintain the order of the system and the integrity of the data.

[0103] Query monitoring module: The query monitoring module is one of the core functions of the monitoring software 32. It allows users to query monitoring data according to specific conditions (such as time period, equipment type, fault type, etc.) and display it to users in the form of charts, reports, etc. In addition, the module can also display the operating status of the power system in real time, such as circuit breaker temperature, current, voltage and other key parameters, so that users can grasp the health of the power system at any time.

[0104] Operation Management Module: The operation management module provides the function of remote operation of the power system. Users can use this module to perform a series of operations, such as starting or stopping equipment, adjusting parameter settings, triggering alarms, etc. This design not only improves operation and maintenance efficiency, but also reduces operation and maintenance costs, because users can manage and maintain the power system without having to visit the site in person.

[0105] By integrating these modules into the monitoring software 32, the embodiment of the present invention not only provides a powerful and easy-to-use monitoring system, but also ensures the safety and efficiency of the system. This design not only meets the power industry's demand for intelligent and automated monitoring systems, but also provides strong support for the safe and stable operation of the power system.

[0106] In one implementation of this embodiment, the wireless temperature sensor 11 is disposed on a circuit breaker of the substation to be tested. This design is intended to achieve accurate and real-time monitoring of the circuit breaker temperature.

[0107] As a key device in a substation, the operating status of the circuit breaker is directly related to the safety and stability of the power system. Temperature is one of the important indicators reflecting the operating status of the circuit breaker, and its changes can often indicate potential failures or abnormalities. Therefore, by installing a wireless temperature sensor 11 on the circuit breaker, the temperature data of the circuit breaker can be obtained in real time, so as to timely discover and deal with potential failure hazards.

[0108] The wireless temperature sensor 11 has the advantages of small size, light weight, and easy installation, and can easily adapt to various complex environments. At the same time, its built-in wireless communication module enables the sensor to transmit temperature data to the data processing and transmission node 2 in real time without laying complex lines, greatly reducing installation and maintenance costs.

[0109] In addition, the wireless temperature sensor 11 also has the characteristics of high precision and high stability, which can ensure the accuracy and reliability of the measured data. This provides strong support for subsequent data analysis and fault warning, allowing operation and maintenance personnel to more accurately grasp the operating status of the power system and take corresponding measures in time to ensure the safe and stable operation of the power system.

[0110] In summary, by setting a wireless temperature sensor 11 on the circuit breaker of the substation to be tested, the implementation example of the present invention not only realizes accurate and real-time monitoring of the circuit breaker temperature, but also provides strong support for the intelligent operation and maintenance of the power system, injecting new vitality into the sustainable development of the power industry.

This can not only effectively reduce the investment in human resources, but also ensure the safety of the operations of operation and maintenance personnel, and is conducive to building a safer, more reliable and efficient power system operation and maintenance system.
