Description

Technical Field

[0001] The present invention relates to the technical field of transformer substation online monitoring, specifically to an online monitoring system remote automatic restart intelligent switch and a control method. Background Art

[0002] At present, online monitoring devices are used in the status monitoring of transformers, high-voltage reactors or lightning arresters to realize continuous monitoring of their status, which has become a relatively mature monitoring technology. Most of the current online monitoring devices are installed outdoors, with poor operating conditions and in long-term power-on operation or standby state. As the operating years increase, online monitoring devices inevitably begin to age and frequently experience offline defects, which also causes the device failure rate to increase year by year. Combined with operation and maintenance experience, it is known that when an online monitoring device is offline or has abnormal data, it is usually caused by a dead program. Most of the defects can be eliminated by powering off and restarting, and it can also be used as a criterion for identifying whether further inspection and troubleshooting work is needed.

[0003] Traditional equipment monitoring and maintenance methods have some obvious disadvantages, as described below:

[0004] 1. High manual dependence: Traditional methods usually rely on regular manual inspections to monitor equipment status, which is not only time-consuming and labor-intensive, but also easily affected by human factors, such as differences in technical level and experience, which may lead to inaccurate or delayed fault diagnosis.

[0005] 2. High maintenance cost: Frequent on-site inspections and maintenance not only require a lot of human resources, but may also involve transportation and travel expenses, making the overall maintenance cost high.

[0006] 3. Safety and reliability issues: Traditional methods may lack sufficient safety measures to prevent misoperation. At the same time, traditional methods may not provide sufficient reliability guarantees for potential risks in complex systems.

[0007] 4. Low equipment maintenance efficiency: Traditional equipment maintenance relies entirely on manual intervention. When equipment fails, it is often necessary to wait for operation and maintenance personnel to arrive on site before handling the problem, resulting in low equipment maintenance efficiency and increasing potential downtime and related losses.

[0008] Therefore, there is an urgent need for an online monitoring system to remotely and automatically restart the intelligent switch to solve the above-mentioned technical problems. Summary of the invention

[0009] The technical problem to be solved by the present invention is to solve the deficiencies in the prior art and to design an online monitoring system remote automatic restart intelligent switch and control method. Therefore, by implementing the remote automatic restart intelligent switch, the workload and cost of on-site maintenance can be reduced, while improving the operating efficiency of the equipment, thereby maximizing cost-effectiveness.

[0056] Embodiment 1

[0057] like Figure 1 and Figure 2 As shown, the present invention provides an online monitoring system remote automatic restart intelligent switch, comprising:

[0058] The front-end monitoring module 100 is responsible for real-time monitoring of the status and performance indicators of the equipment and issuing warning information;

[0059] Communication module 200, responsible for communicating with a remote monitoring center or other management system, receiving remote commands and sending device status information;

[0060] The backend monitoring platform 300 is used to remotely monitor the device status, send restart instructions, and view operation results and system logs.

[0061] In the embodiment of the present invention, the status and performance indicators of the equipment are monitored in real time through the front-end monitoring module. When an abnormal situation is found, a warning message is issued to remind the staff to operate. The front-end monitoring module collects data from the equipment and communicates with the background monitoring platform through the communication module. The background monitoring platform outputs instructions according to the received monitoring data and controls the front-end monitoring module to perform restart operations, etc. The remote Zixiong restart intelligent switch provided by the present invention can make judgments based on the monitored data information and realize automatic restart and warning functions, thereby improving the safety and reliability of the equipment. For the equipment restart operation, there is no need for staff to operate on site, and automatic startup can be achieved through remote control, which is convenient to operate, reduces equipment downtime, and achieves rapid response and recovery.

[0062] See also Figure 3 , the front-end monitoring module includes:

[0063] The signal acquisition module 101 collects the status and performance index data of the monitoring equipment through the sensor group, and issues a warning message to remind the offline defect when the data is offline and cannot receive real-time data;

[0064] The control module 102 executes a decision algorithm based on the data provided by the signal acquisition module to determine whether a restart operation is required;

[0065] The execution module 103 receives the execution instruction of the control module and implements the actual restart operation through the relay;

[0066] The security module 104 is used to ensure the security of the restart process and prevent accidental operation or illegal access;

[0067] The power module 105 is used to control the power supply of the device when performing a restart operation.

[0068] In the embodiment of the present invention, the monitoring module is responsible for real-time monitoring of the status and performance indicators of the equipment, such as voltage, current, temperature and oil chromatography data. The monitoring module is the basis of the remote automatic restart system. It can provide real-time data of the equipment for subsequent fault analysis and judgment. At the same time, the monitoring module also has a data disconnection warning function. If the remote monitoring system cannot receive real-time data, a warning message will be issued to promptly remind the staff of the disconnection defect. The module includes a main control chip and a sensor, etc. The sensor collects the performance indicator data of the monitoring equipment, and processes the data through the main control chip to achieve the purpose of remote monitoring.

[0069] Based on the data provided by the monitoring module, the control module executes a decision algorithm to determine whether a restart operation is required. Through simple threshold judgment, if a disconnection defect or data abnormality occurs, the remote staff is notified to issue a restart instruction, and the restart operation is implemented through the control module. This module is mainly composed of a data storage device and a control chip. The data information stored in the data storage device is compared with the collected data. Once an abnormality or disconnection defect occurs (the collected data is empty), a restart operation is required. The judgment logic is as follows:

[0070]

[0071] Among them: F (x) represents the judgment function, x represents the data collected in real time, when F (x) =0 means the collected data does not meet the threshold requirement, and a restart is required. Indicates the threshold value. When the collected data meets the threshold requirement, F (x) =1, which is the normal state.

[0072] Under the instruction of the control module, the execution module implements the actual restart operation through the relay, wherein the restart operation includes cutting off the power supply and sending a specific restart signal to the device to restart the device.

[0073] The security module is developed through the vivado development platform to ensure the security of the entire restart process and prevent accidental operations or illegal access. The security module may include functions such as user authentication, permission control, and operation log recording.

[0074] When the power management module performs a restart operation, the power management module is responsible for controlling the power supply of the device to ensure that the device can be restarted safely in a predetermined manner.

[0075] In the embodiment of the present invention, the communication module is responsible for communicating with the remote monitoring center or other management systems, receiving remote commands and sending device status information. The communication module needs to support multiple communication protocols and ensure the security and reliability of data transmission. Figure 3 , the communication module 200 includes:

[0076] The first communication module 201 is provided in the front-end monitoring module and is used to send information to the back-end monitoring platform;

[0077] The second communication module 202, which is arranged in the background monitoring platform, is used to send control instructions to the control module.

[0078] See also Figure 1 , the background monitoring platform 300 includes:

[0079] User interface module 301, used by staff to remotely monitor device status, send restart instructions, and view operation results and system logs;

[0080] The fault recording and analysis module 302 records the fault history and restart log of the device for subsequent fault analysis and maintenance decision support.

[0081] The user interface module uses C language to develop the user interface, providing users with a convenient and fast operation interface, allowing staff to remotely monitor the status of the equipment, send restart instructions, and view operation results and system logs. The fault recording and analysis module records the fault history and restart log of the equipment for subsequent fault analysis and maintenance decision support. The functions of this module are implemented by the data storage and the main control chip. The data in the storage is accessed for viewing, and the main control chip completes the data analysis. At the same time, the module can also clear the stored data through instructions.

[0082] The present invention ensures that the remote automatic restart system can effectively monitor the device status, respond to failures in a timely manner, and safely perform the restart operation through the above modules working together. In this way, the reliability and operation and maintenance efficiency of the system can be significantly improved.

[0083] See also Figure 4 , which is a wiring schematic diagram of the remote automatic restart intelligent switch of the online monitoring system proposed in the present invention, wherein the remote automatic restart intelligent switch is connected to the external power supply through the internally arranged switch power supply, the control module is connected to the programmable circuit breaker through the RS485 bus to control the restart of the equipment such as the oil chromatography online monitoring device, the status and performance indicators of the equipment are collected through the data acquisition module and transmitted to the memory inside the automatic restart intelligent switch, and the communication module communicates with the background monitoring platform.

[0084] See also Figure 5 The present invention proposes a remote automatic restart intelligent switch control method for an online monitoring system, which specifically includes:

[0085] Initialize and configure the system, configure the communication module, security module and start the monitoring module; install the smart switch hardware and ensure that all sensors and actuators are correctly connected; configure the communication module to ensure that the smart switch can establish a stable communication connection with the remote monitoring center or other management systems; set up the security module, including user authentication, authority allocation and security policy; start the monitoring module, configure sensor parameters, and ensure that the equipment status data can be accurately collected.

[0086] Remote monitoring and debugging: monitor the device status and performance indicators in real time through the background monitoring platform to determine whether to restart; monitor the device status and performance indicators in real time through the user interface module, view the monitoring data, and use the control module to diagnose faults. When potential problems, performance degradation, or offline defects are detected (the collected data is empty), instructions are issued according to preset rules, and the staff decides whether a restart is needed.

[0087] Remote automatic restart operation, if the control module determines that a restart is needed, it controls the execution module to perform the restart operation; remote automatic restart operation, if the control module determines that a restart is needed, it automatically sends a restart instruction to the execution module, and the execution module performs the restart operation according to the instruction, such as cutting off the power supply, sending a restart signal, etc. During the restart process, the power management module is responsible for controlling the power supply to ensure the safe restart of the equipment.

[0088] Check and recover after restart. After restart, the monitoring module monitors and analyzes the equipment status and performance indicators after restart to determine whether they have returned to normal. After the equipment restarts, the monitoring module restarts and continues to collect equipment status data. The control module analyzes the data after restart to confirm whether the equipment has returned to normal operation. If the equipment fails to start normally or there are other problems, the user interface module will display the corresponding fault information for further processing by the operation and maintenance personnel.

[0089] Log recording and reporting, record all restart events and operation logs through the fault recording and analysis module, and generate system reports. The fault recording and analysis module records all restart events and operation logs, and generates system reports, including the cause of the fault, the restart process, and the equipment recovery status, for subsequent analysis and improvement.
