Description

Technical Field

[0001] This invention belongs to the field of power distribution station monitoring technology, and in particular relates to an intelligent monitoring device and method for a power distribution station room. Background Technology

[0002] With the continuous development of power systems, the monitoring and management of substations have become increasingly important. Currently, most monitoring methods rely on periodic manual inspections, and the monitoring results are diagnosed manually. Therefore, existing monitoring methods suffer from low efficiency and the inability to monitor and diagnose in real time.

[0003] Furthermore, the cost of operation and maintenance for a single substation is limited, making it difficult to deploy hundreds of various sensors for comprehensive online monitoring like a substation. Universal, comprehensive monitoring of substations is only suitable for demonstration substations and a small number of substations with very high protection levels. Conversely, installing fixed sensors in certain designated substations for online monitoring of specific defects is insufficient to meet the comprehensive monitoring needs of those substations, and also fails to address the monitoring requirements of other substations.

[0004] Therefore, there is an urgent need for an intelligent monitoring device that can be quickly deployed for substations and can comprehensively monitor and diagnose the status of substations. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent monitoring device and method for substation rooms, which can enable rapid deployment and comprehensive monitoring and diagnosis of the substation room's status.

The equipment status monitoring device is used to collect monitoring data from the electrical equipment in the substation room. The communication device provides WiFi and LoRa signals to enable communication between the equipment status monitoring device, the smart monitoring mobile terminal, and the side-side diagnostic device.

Based on the received monitoring data, the status of the high-voltage switchgear is diagnosed, and the received monitoring data and diagnostic results are stored and reported to the mobile terminal. If the electrical equipment is a distribution transformer, the received monitoring data includes: visible light images collected by a dual-spectrum panoramic camera and UHF partial discharge signals collected by a UHF partial discharge sensor. The status of the distribution transformer is diagnosed based on the received monitoring data, and the received monitoring data and diagnostic results are stored and reported to the intelligent monitoring mobile terminal.

The method includes: Based on user operation, the intelligent monitoring mobile terminal is used to configure the monitoring of the substation room, and after the configuration is completed, the monitoring is started.

After the WiFi sensor is connected to the network, the image information collected by the WiFi sensor is obtained by the smart monitoring mobile terminal. Based on the image information, the electrical equipment being monitored is determined, and the association relationship between the WiFi sensor and the equipment ledger of the substation is established using the associated operation interface provided by the smart monitoring mobile terminal.

[0013] Furthermore, the intelligent monitoring method for substation rooms provided by this invention also includes: WiFi sensor network access steps: The WiFi sensor searches for and attempts to connect to the local WiFi network based on the pre-configured local WiFi name and access password. The communication device traverses the access devices within the network segment according to the preset IP address range of the WiFi sensors in order to discover WiFi sensors that are trying to access. Each WiFi sensor is pre-assigned an independent IP address within the IP address range. The communication device attempts to log in to the standard services of the WiFi sensor and determines the device type of the WiFi sensor based on whether the login is successful. LoRa sensor network access steps: The intelligent monitoring mobile terminal sends the LoRa sensor information obtained by scanning the QR code to the communication device; The communication device establishes a LoRa access whitelist for the LoRa sensor to enable the LoRa sensor to access the network; After the WiFi sensor and LoRa sensor are registered with the network, perform the following configuration steps: The communication device sends information and network access status of LoRa and WiFi sensors to the smart monitoring mobile terminal, so that the smart monitoring mobile terminal can display the list of indoor electrical equipment and network-connected sensors.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The intelligent monitoring equipment for substations provided by this invention, through a device storage compartment combined with a detachable equipment status monitoring device design, solves the problems of high investment per station and applicability only to specific substations caused by traditional fixed sensors. A single set of equipment can be flexibly deployed in different substations, achieving monitoring resource reuse, reducing the operation and maintenance costs of multiple substations, and meeting universal monitoring needs. The equipment integrates the entire process of data acquisition, communication transmission, local diagnostics, and visualization, overcoming the pain points of low efficiency and high lag in traditional manual inspections. It achieves near real-time monitoring, automatic diagnosis, and intuitive display of substation status, improving operation and maintenance response speed. The communication device provides both WiFi and LoRa signals, allowing flexible selection of communication links based on sensor type, resolving the contradiction between high real-time performance and low power consumption in monitoring, and ensuring data transmission stability and efficiency.

[0015] 2. By establishing a connection between sensors and electrical equipment through a smart monitoring mobile terminal and synchronizing the data to the side-side diagnostic device, this solves the problems of poor adaptability and the need for redeployment in the traditional fixed binding mode. It ensures that the side-side diagnostic device can accurately locate the equipment corresponding to the monitoring data, improving the accuracy and relevance of the diagnostic results. This smart monitoring equipment provides two ledger generation methods: OCR recognition of on-site equipment and template selection. It eliminates the need for manual input of equipment information, adapting to complex on-site environments and improving the efficiency of preparation before monitoring in the substation. LoRa sensors quickly associate with the ledger via QR code scanning, while WiFi sensors identify and associate monitoring equipment based on image information. Combined with the association operation interface of the smart monitoring mobile terminal, it enables association simply by scanning a code and viewing an image, reducing deployment difficulty and enabling rapid deployment monitoring. Furthermore, the association process is standardized, requiring no reliance on operator experience, ensuring that different personnel can quickly complete the association, improving the repeatability and universality of the method.

[0016] 3. The intelligent monitoring equipment for power distribution rooms provided by this invention can self-organize a network on-site. WiFi sensors automatically discover themselves by traversing IP network segments, and LoRa sensors automatically gain access through a whitelist. No manual configuration of network parameters is required for each sensor, enabling immediate network access upon power-on and significantly improving deployment efficiency. Simultaneously, the communication device sends sensor information and network access status to the intelligent monitoring mobile terminal, allowing users to intuitively view the online status of sensors, promptly identify unconnected devices, and troubleshoot problems, avoiding monitoring interruptions due to device offline status.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0019] The following detailed description is exemplary and intended to provide further detailed explanation of the invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention.

[0020] Example 1 This invention provides an intelligent monitoring device for a substation room, such as... Figure 1 As shown, the device includes: a device storage compartment 11, a device status monitoring device 12, a side diagnostic device 13, a smart monitoring mobile terminal 14, and a communication device 15. In this embodiment of the invention, as... Figure 2 As shown, the device storage compartment 11 is in the form of a toolbox, including a base and a cover. One side of the cover is hinged to the base, allowing the cover to open and close on one side. A side diagnostic device 13 and a communication device 105 are installed inside the device storage compartment 11. A smart monitoring mobile terminal 14 and an equipment status monitoring device 12 are detachably installed in the device storage compartment 11, allowing the equipment status monitoring device 12 to be retrieved from the device storage compartment 11 and deployed inside the substation room during on-site monitoring.

[0021] Equipment status monitoring device 12 is used to collect monitoring data of electrical equipment in the substation room. Communication device 15 is used to provide WiFi and LoRa signals to enable communication between the equipment status monitoring device, the smart monitoring mobile terminal, and the side-side diagnostic device. Side-side diagnostic device 13 is used to receive the monitoring data collected by the equipment status monitoring device, diagnose the status of the electrical equipment based on the monitoring data, store the diagnostic results and monitoring data, and report them to the smart monitoring mobile terminal. Smart monitoring mobile terminal 14 is used to display the monitoring interface of the substation room based on the received diagnostic results and monitoring data, and to configure the monitoring of the substation room based on user operations and control the start and stop of monitoring.

[0022] The above-mentioned reporting of monitoring data and diagnostic results of various electrical devices to the mobile terminal can be implemented in the following way: if there is an alarm in the diagnostic results, the monitoring data and diagnostic results are reported immediately; if there is no alarm in the diagnostic results, the monitoring data and diagnostic results are reported periodically.

[0023] For the intelligent monitoring mobile terminal, it receives diagnostic results and monitoring data from various devices, displays the monitoring interface of the substation, and promptly alerts users when anomalies are detected in the diagnostic results. Furthermore, the received diagnostic results and monitoring data from various devices can be uploaded to the cloud platform for further analysis and to push maintenance strategies to users.

[0024] The intelligent monitoring equipment for substations provided by this invention, through a device storage compartment combined with a detachable equipment status monitoring device design, solves the problems of high investment per station and applicability only to specific substations caused by traditional fixed sensors. A single set of equipment can be flexibly deployed in different substations, achieving monitoring resource reuse, reducing the operation and maintenance costs of multiple substations, and meeting universal monitoring needs. The equipment integrates the entire process of data acquisition, communication transmission, local diagnostics, and visualization, overcoming the pain points of low efficiency and high lag in traditional manual inspections. It achieves near real-time monitoring, automatic diagnosis, and intuitive display of substation status, improving operation and maintenance response speed. The communication device provides both WiFi and LoRa signals, allowing flexible selection of communication links based on sensor type, resolving the contradiction between high real-time performance and low power consumption in monitoring, and ensuring data transmission stability and efficiency.

[0025] In the application scenarios provided in the embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the types of electrical equipment to be monitored in the substation room are high-voltage switchgear, distribution transformers, and low-voltage switchgear.

[0026] The equipment status monitoring device includes a WiFi sensor and a LoRa sensor. The communication device includes a WiFi module and a LoRa module. The WiFi module provides a WiFi signal, enabling the smart monitoring mobile terminal and WiFi sensors to communicate with the side-side diagnostic device via the station's WiFi. The LoRa module provides a LoRa signal, enabling the LoRa sensor to communicate with the side-side diagnostic device via LoRa. Therefore, this smart monitoring equipment can adapt to the transmission needs of different monitoring devices within the substation.

[0027] The WiFi sensors specifically include a visual ultrasonic array and a dual-spectrum panoramic camera. The LoRa sensors specifically include a dual-ultrasonic partial discharge sensor and a UHF partial discharge sensor. The visual ultrasonic array and dual-ultrasonic partial discharge sensor are used to collect monitoring data from high-voltage switchgear, while the UHF partial discharge sensor and dual-spectrum panoramic camera are used to collect monitoring data from distribution transformers. The dual-spectrum panoramic camera is also used to collect monitoring data from low-voltage switchgear. That is... Figure 2 As shown, the device storage compartment is used to store the visualization ultrasonic array, dual ultrasonic partial discharge sensors, ultra-high frequency partial discharge sensors, and a dual-spectrum panoramic camera (not shown in the figure). Before monitoring, the user can remove the above sensors from the device storage compartment and deploy them at the corresponding monitoring locations.

[0028] The visualized ultrasonic array integrates an ozone sensor and a temperature and humidity sensor. The visualized ultrasonic array is mainly used to collect visualized ultrasonic signals (corresponding to 83*47 grids), ozone concentration, temperature value, and humidity value from high-voltage switchgear.

[0029] The dual ultrasonic partial discharge sensor is mainly used to collect inward ultrasonic signals, outward ultrasonic signals, and transient ground voltage signals from high-voltage switchgear. Furthermore, in some embodiments, it can also collect the number of inward pulses, the number of outward pulses, and the number of transient ground voltage pulses.

[0030] Dual-spectrum panoramic cameras are used to acquire visible light images of distribution transformers to monitor winding temperatures. They are also used to acquire visible and infrared images of low-voltage switchgear to monitor the switching status and surface / inter-slot temperatures.

[0031] Ultra-high frequency partial discharge (UHF) sensors are used to collect UHF partial discharge signals from distribution transformers in order to monitor the partial discharge of the distribution transformers based on these signals.

[0032] Regarding the aforementioned sensors, the data collection frequency can be set to 10 minutes. This invention does not limit the scope of the invention; in specific embodiments, those skilled in the art can set the frequency according to actual needs.

[0033] In this embodiment of the invention, the intelligent monitoring mobile terminal is also used to associate the equipment status monitoring device with the electrical equipment in the substation room based on user operation, and send the association relationship to the side diagnostic device so that the side diagnostic device can diagnose the status of the associated electrical equipment based on the monitoring data collected by the equipment status monitoring device.

[0034] Compared to traditional monitoring systems that are fixedly installed in substation rooms, with sensors and monitored electrical equipment bound one-to-one, the intelligent monitoring device for substation rooms provided by this invention is a multi-functional, portable system. One device can cover multiple substation rooms and can be used cyclically for monitoring multiple substation rooms, meeting the comprehensive monitoring and diagnostic needs of multiple substation rooms. Considering the potential model differences of electrical equipment in different substation rooms, this intelligent monitoring device for substation rooms adopts a dynamic association mechanism, re-establishing the mapping relationship between the device and the sensor each time it is deployed.

[0035] In this embodiment of the invention, the side diagnostic device is used for: If the electrical equipment is a high-voltage switchgear, the received monitoring data includes: visual ultrasonic signals, ozone concentration, temperature value, and humidity value collected by the visual ultrasonic array, as well as inward ultrasonic signals, outward ultrasonic signals, and transient ground voltage signals collected by the dual ultrasonic partial discharge sensors. Based on the received monitoring data, the status of the high-voltage switchgear is diagnosed, and the received monitoring data and diagnostic results are stored and reported to the mobile terminal.

[0036] More specifically, in this embodiment, for the diagnosis of high-voltage switchgear, the dual-ultrasound mechanism diagnosis result is obtained based on the inward ultrasonic signal, outward ultrasonic signal, inward pulse count, and outward pulse count transmitted by dual ultrasonic partial discharge sensors via the power transmission and transformation IoT LoRa. Similarly, the transient ground mechanism diagnosis result is obtained based on the transient ground voltage signal and transient ground voltage pulse count transmitted by dual ultrasonic partial discharge sensors via the power transmission and transformation IoT LoRa. If either of these two diagnostic results indicates partial discharge, the final diagnosis is partial discharge. Furthermore, the visualized ultrasonic signal transmitted via station WiFi through a visualized ultrasonic array is used to analyze and diagnose the three-level ultrasonic signals of the station room, switchgear, and cabinet gap.

[0037] If the electrical equipment is a distribution transformer, the received monitoring data includes: visible light images collected by a dual-spectrum panoramic camera and UHF partial discharge signals collected by a UHF partial discharge sensor. The status of the distribution transformer is diagnosed based on the received monitoring data, and the received monitoring data and diagnostic results are stored and reported to the intelligent monitoring mobile terminal.

[0038] More specifically, in this embodiment, for the diagnosis of the distribution transformer, the three-phase temperature values ​​of A / B / C are obtained from the visible light images transmitted by the dual-spectrum panoramic camera via the station's WiFi. Then, based on the individual temperature values ​​of the three phases and the pairwise temperature differences between the three phases, it is determined whether the winding temperature is too high or the interphase temperature difference is too large. In addition, based on the UHF partial discharge signal transmitted by the UHF partial discharge sensor via the power transmission and transformation IoT LoRa, partial discharge spectrum diagnosis and mechanism characteristic diagnosis are performed to determine whether the distribution transformer has partial discharge.

[0039] If the electrical equipment is a low-voltage switchgear, the received monitoring data includes: visible light images and infrared light images collected by a dual-spectrum panoramic camera, and the status of the low-voltage switchgear is diagnosed based on these images. The received monitoring data and diagnostic results are stored and reported to the intelligent monitoring mobile terminal.

[0040] More specifically, in this embodiment, for the diagnosis of low-voltage switchgear, the color characteristics of the opening and closing indicator lights are obtained from the visible light images transmitted by the dual-spectrum panoramic camera via the station's WiFi. These colors are then compared with the color characteristics of the previously sampled lights to determine if the opening and closing status has changed. Additionally, the cabinet surface temperature is obtained from the infrared light images transmitted by the dual-spectrum panoramic camera via the station's WiFi. Then, by performing a lateral comparison of the internal temperature difference and analyzing the peak temperature difference between cabinets, it is determined whether there are areas of excessively high temperature or excessively large temperature differences on the cabinet surface.

[0041] The side-side diagnostic device supports near real-time data acquisition from sensors deployed within the station, with full storage of data throughout the power supply period. It supports data from over 3 months of monitoring at a frequency of 10 minutes per station. It incorporates specialized small-model basic diagnostic algorithms for partial discharge, infrared, and temperature, enabling near real-time diagnosis of the status of distribution transformers and high- and low-voltage switchgear.

[0042] In this embodiment of the invention, the communication device supports on-site WiFi and LoRa self-organizing network, one-click WiFi local area network and power transmission and transformation IoT (LoRa470M) on-site coverage, intelligent monitoring mobile terminal, ultrasonic array, and dual-spectrum panoramic camera communicate via on-site WiFi, and dual ultrasonic and UHF partial discharge sensors communicate via power transmission and transformation IoT. Below, as... Figure 5 The following describes the configuration and networking process of the intelligent monitoring device for the substation room based on the present invention for monitoring the substation room: First, users can take out the sensors and smart monitoring mobile terminals from the smart monitoring equipment in the substation room, deploy the sensors on site, and after the hardware deployment is completed, the smart monitoring equipment in the substation room is powered on, and the communication device automatically turns on the WiFi network and LoRa network.

[0043] After the smart monitoring mobile terminal is powered on, it automatically connects to the smart monitoring device via WiFi.

[0044] The intelligent monitoring mobile terminal is used to perform OCR recognition on the electrical equipment on site to obtain the corresponding electrical equipment information and generate the equipment ledger of the substation room. Alternatively, the intelligent monitoring mobile terminal can be used to generate the equipment ledger of the substation room by selecting the electrical equipment on site in the pre-configured typical substation template interface.

[0045] Network access steps for LoRa sensors (dual ultrasonic, UHF partial discharge sensors): Scan the QR code of the LoRa sensor using a smart monitoring mobile terminal to obtain the corresponding LoRa sensor information, and then use the associated operation interface provided by the smart monitoring mobile terminal (such as...) Figure 6 As shown in the figure, establish the association between the LoRa sensor and the equipment ledger of the substation room.

[0046] The intelligent monitoring mobile terminal sends the LoRa sensor information obtained by scanning the QR code to the communication device.

[0047] The communication device establishes a LoRa access whitelist for the LoRa sensor, allowing it to access the network.

[0048] After powering on the LoRa sensor, attempt to connect via LoRa.

[0049] Network access steps for WiFi sensors (visualized ultrasonic arrays, dual-spectrum panoramic cameras, i.e., IP sensing devices): After the WiFi sensor is powered on, it searches for and attempts to connect to the local WiFi network based on the pre-configured local WiFi name and access password. When the visual ultrasound array and dual-spectrum panoramic camera use WiFi communication, the local target WiFi network and access password are pre-configured. The visual ultrasound array and dual-spectrum panoramic camera provide standard services to external users.

[0050] The communication device traverses access devices within a network segment based on a preset IP address range for WiFi sensors to automatically discover WiFi sensors attempting to connect. Each WiFi sensor is pre-assigned a unique, fixed IP address within its IP address range, and these addresses are recorded to prevent future duplication. The communication device has pre-recorded all possible allowed IP address ranges for visual ultrasonic arrays and dual-spectrum panoramic cameras. These IP addresses can be considered as Class C addresses (254 addresses), but this invention does not limit this.

[0051] The communication device attempts to log in to the standard services of the WiFi sensor and determines the type of WiFi sensor based on whether the login is successful. Then, based on the device type, it accesses the device to extract video and images.

[0052] After the WiFi sensor is connected to the network, the image information collected by the WiFi sensor is acquired using a smart monitoring mobile terminal. Specifically, visible light images are extracted from both the dual-spectrum panoramic camera and the ultrasonic array. Based on the image information, the monitored electrical equipment is determined (many-to-many relationships are allowed). The association relationship between the WiFi sensor and the equipment ledger in the substation is established using the association operation interface provided by the smart monitoring mobile terminal. For example, based on the visible light images of the visualized ultrasonic array, the monitoring range of multiple high-voltage switchgear cabinets is determined. If a cabinet is covered by two sensors, an association is established for both.

[0053] After the WiFi sensor and LoRa sensor are connected to the network, perform the following further configuration steps: The communication device sends information and network access status of the LoRa and WiFi sensors to the smart monitoring mobile terminal, which then displays a list of indoor electrical equipment and network-connected sensors. Users can check the online status of each sensor on the smart monitoring mobile terminal, and can also take photos of the sensor's specific installation location and save them.

[0054] Users can set and issue sampling cycles based on the intelligent monitoring mobile terminal, and can also issue monitoring start commands based on the intelligent monitoring mobile terminal.

[0055] If a user discovers that some sensors are missing after the monitoring equipment is running, or that adjustments need to be made to the monitored electrical equipment or sensor register, monitoring must be stopped and the device reconfigured in configuration mode. The intelligent monitoring mobile terminal does not upload or download data in configuration mode to avoid overloading.

[0056] Based on the above configuration steps, the intelligent monitoring equipment in the substation provided by this invention achieves self-organizing network on-site. WiFi sensors automatically discover themselves by traversing IP network segments, and LoRa sensors are automatically admitted through a whitelist. No manual configuration of network parameters is required for each sensor, enabling immediate network access upon power-on and significantly improving deployment efficiency. The network access status is visualized, facilitating on-site troubleshooting: the communication device sends sensor information and network access status to the intelligent monitoring mobile terminal, allowing users to intuitively view the online status of sensors, promptly identify unconnected devices, and troubleshoot problems, avoiding monitoring interruptions due to device offline.

[0057] The intelligent monitoring mobile terminal offers two ledger generation methods: OCR recognition of on-site equipment and template selection. This eliminates the need for manual data entry of each device, adapting to complex on-site environments and improving preparation efficiency before monitoring in substations. LoRa sensors quickly associate with ledgers via QR code scanning, while WiFi sensors identify and associate monitoring devices based on image information. Combined with the intelligent monitoring mobile terminal's association interface, this allows for association simply by scanning a code and viewing an image, reducing deployment difficulty and enabling rapid monitoring deployment. Furthermore, the association process is standardized, requiring no reliance on operator experience, ensuring that different personnel can quickly complete the association process, improving the repeatability and universality of the method.

[0058] Meanwhile, the intelligent monitoring equipment for substation rooms provided by this invention is portable and reusable, adaptable to the needs of different scenarios. It achieves near real-time monitoring of the high-voltage side through a visual ultrasonic array and dual ultrasonic partial discharge, and near real-time monitoring of the distribution transformer and low-voltage side through a dual-spectrum panoramic camera. It also supports full storage of data collected by sensors deployed within the substation during the power supply guarantee period. Furthermore, this invention enables self-organizing networks of WiFi and LoRa within the substation, facilitating rapid deployment of substation room status monitoring and resolving the inherent trade-off between high real-time performance and low power consumption in substation room monitoring. This achieves flexible and rapid deployment, accurate and real-time monitoring and diagnosis of substation room status monitoring.

[0059] Example 2 like Figure 7 As shown, based on the same inventive concept as the above embodiments, the present invention also provides an intelligent monitoring method for a substation room. This method is implemented based on the intelligent monitoring device for a substation room provided in Embodiment 1. The intelligent monitoring device includes: a device storage compartment, a side-side diagnostic device and a communication device installed within the device storage compartment, and an intelligent monitoring mobile terminal and a device status monitoring device detachably installed within the device storage compartment, allowing the device status monitoring device to be removed and deployed inside the substation room. The communication device provides WiFi and LoRa signals to enable communication between the device status monitoring device, the intelligent monitoring mobile terminal, and the side-side diagnostic device. The intelligent monitoring method includes the following steps: Step S1: Based on user operation, the intelligent monitoring mobile terminal is used to configure the monitoring of the substation room, and after the configuration is completed, the monitoring is started.

[0060] Step S2: The equipment status monitoring device collects monitoring data of the electrical equipment in the substation room.

[0061] In step S3, the side diagnostic device receives the monitoring data collected by the equipment status monitoring device, diagnoses the status of the electrical equipment based on the monitoring data, stores the diagnostic results and monitoring data, and reports them to the intelligent monitoring mobile terminal.

[0062] Step S4: The intelligent monitoring mobile terminal displays the monitoring interface of the substation room based on the received diagnostic results and monitoring data.

[0063] Furthermore, in step S1, the process of monitoring and configuring the substation room using a smart monitoring mobile terminal based on user operation includes: The intelligent monitoring mobile terminal associates the equipment status monitoring device with the electrical equipment in the substation room based on user operation, and sends the association relationship to the side diagnostic device so that the side diagnostic device can diagnose the status of the associated electrical equipment based on the monitoring data collected by the equipment status monitoring device.

[0064] In the application scenario provided by this invention embodiment, the types of electrical equipment to be monitored in the substation room are high-voltage switchgear, distribution transformers, and low-voltage switchgear. In this embodiment, the equipment status monitoring device includes: a WiFi sensor and a LoRa sensor; the communication device includes: a WiFi module and a LoRa module. The WiFi module is used to provide WiFi signals so that the intelligent monitoring mobile terminal and WiFi sensor can communicate with the side-side diagnostic device via the station's WiFi; the LoRa module is used to provide LoRa signals so that the LoRa sensor can communicate with the side-side diagnostic device via LoRa. The WiFi sensor includes: a visual ultrasonic array and a dual-spectrum panoramic camera; the LoRa sensor includes: a dual ultrasonic partial discharge sensor and a UHF partial discharge sensor.

[0065] The visualized ultrasonic array integrates an ozone sensor and a temperature and humidity sensor. The visualized ultrasonic array is mainly used to collect visualized ultrasonic signals (corresponding to 83*47 grids), ozone concentration, temperature value, and humidity value from high-voltage switchgear.

[0066] The dual ultrasonic partial discharge sensor is mainly used to collect inward ultrasonic signals, outward ultrasonic signals, and transient ground voltage signals from high-voltage switchgear. Furthermore, in some embodiments, it can also collect the number of inward pulses, the number of outward pulses, and the number of transient ground voltage pulses.

[0067] Dual-spectrum panoramic cameras are used to acquire visible light images of distribution transformers to monitor winding temperatures. They are also used to acquire visible and infrared images of low-voltage switchgear to monitor the switching status and surface / inter-slot temperatures.

[0068] Ultra-high frequency partial discharge (UHF) sensors are used to collect UHF partial discharge signals from distribution transformers in order to monitor the partial discharge of the distribution transformers based on these signals.

[0069] Step S2, the equipment condition monitoring device collects monitoring data of electrical equipment in the substation room, specifically including: Monitoring data of high-voltage switchgear is collected using a visual ultrasonic array and dual ultrasonic partial discharge sensors; monitoring data of distribution transformers is collected using an ultra-high frequency partial discharge sensor and a dual-spectrum panoramic camera; and monitoring data of low-voltage switchgear is collected using a dual-spectrum panoramic camera.

[0070] Step S3, which diagnoses the condition of electrical equipment based on monitoring data, includes: If the electrical equipment is a high-voltage switchgear, the received monitoring data includes: visual ultrasonic signals, ozone concentration, temperature value, and humidity value collected by the visual ultrasonic array, as well as inward ultrasonic signals, outward ultrasonic signals, and transient ground voltage signals collected by the dual ultrasonic partial discharge sensors. Based on the received monitoring data, the status of the high-voltage switchgear is diagnosed, and the received monitoring data and diagnostic results are stored and reported to the intelligent monitoring mobile terminal.

[0071] More specifically, in this embodiment, for the diagnosis of high-voltage switchgear, the dual-ultrasound mechanism diagnosis result is obtained based on the inward ultrasonic signal, outward ultrasonic signal, inward pulse count, and outward pulse count transmitted by dual ultrasonic partial discharge sensors via the power transmission and transformation IoT LoRa. Similarly, the transient ground mechanism diagnosis result is obtained based on the transient ground voltage signal and transient ground voltage pulse count transmitted by dual ultrasonic partial discharge sensors via the power transmission and transformation IoT LoRa. If either of these two diagnostic results indicates partial discharge, the final diagnosis is partial discharge. Furthermore, the visualized ultrasonic signal transmitted via station WiFi through a visualized ultrasonic array is used to analyze and diagnose the three-level ultrasonic signals of the station room, switchgear, and cabinet gap.

[0072] If the electrical equipment is a distribution transformer, the received monitoring data includes: visible light images collected by a dual-spectrum panoramic camera and UHF partial discharge signals collected by a UHF partial discharge sensor. The status of the distribution transformer is diagnosed based on the received monitoring data, and the received monitoring data and diagnostic results are stored and reported to the intelligent monitoring mobile terminal.

[0073] More specifically, in this embodiment, for the diagnosis of the distribution transformer, the three-phase temperature values ​​of A / B / C are obtained from the visible light images transmitted by the dual-spectrum panoramic camera via the station's WiFi. Then, based on the individual temperature values ​​of the three phases and the pairwise temperature differences between the three phases, it is determined whether the winding temperature is too high or the interphase temperature difference is too large. In addition, based on the UHF partial discharge signal transmitted by the UHF partial discharge sensor via the power transmission and transformation IoT LoRa, partial discharge spectrum diagnosis and mechanism characteristic diagnosis are performed to determine whether the distribution transformer has partial discharge.

[0074] If the electrical equipment is a low-voltage switchgear, the received monitoring data includes: visible light images and infrared light images collected by a dual-spectrum panoramic camera, and the status of the low-voltage switchgear is diagnosed based on these images. The received monitoring data and diagnostic results are stored and reported to the intelligent monitoring mobile terminal.

[0075] More specifically, in this embodiment, for the diagnosis of low-voltage switchgear, the color characteristics of the opening and closing indicator lights are obtained from the visible light images transmitted by the dual-spectrum panoramic camera via the station's WiFi. These colors are then compared with the color characteristics of the previously sampled lights to determine if the opening and closing status has changed. Additionally, the cabinet surface temperature is obtained from the infrared light images transmitted by the dual-spectrum panoramic camera via the station's WiFi. Then, by performing a lateral comparison of the internal temperature difference and analyzing the peak temperature difference between cabinets, it is determined whether there are areas of excessively high temperature or excessively large temperature differences on the cabinet surface.

[0076] Furthermore, the steps for the intelligent monitoring mobile terminal to associate the equipment status monitoring device with the electrical equipment in the substation room based on user operation include: The intelligent monitoring mobile terminal can be used to perform OCR recognition on the electrical equipment on site to obtain the corresponding electrical equipment information and generate the equipment ledger of the substation room. Alternatively, the intelligent monitoring mobile terminal can be used to generate the equipment ledger of the substation room by selecting the electrical equipment on site in the pre-configured typical substation template interface.

[0077] By scanning the QR code of the LoRa sensor using a smart monitoring mobile terminal, the corresponding LoRa sensor information can be obtained. Then, by using the associated operation interface provided by the smart monitoring mobile terminal, the association between the LoRa sensor and the equipment ledger of the substation can be established.

[0078] After the WiFi sensor is connected to the network, the image information collected by the WiFi sensor is obtained by the smart monitoring mobile terminal. Based on the image information, the electrical equipment being monitored is determined, and the association relationship between the WiFi sensor and the equipment ledger of the substation is established using the associated operation interface provided by the smart monitoring mobile terminal.

[0079] In this embodiment of the invention, the intelligent monitoring method for the substation room also includes the following self-organizing network process of WiFi and LoRa within the substation: WiFi sensor network access steps: The WiFi sensor searches for and attempts to connect to the local WiFi network based on the pre-configured local WiFi name and access password.

[0080] The communication device traverses the access devices within the network segment according to the preset IP address range of the WiFi sensors in order to discover WiFi sensors that are trying to access. Each WiFi sensor is pre-assigned an independent IP address within the IP address range.

[0081] The communication device attempts to log in to the standard services of the WiFi sensor and determines the device type of the WiFi sensor based on whether the login is successful.

[0082] LoRa sensor network access steps: The intelligent monitoring mobile terminal sends the LoRa sensor information obtained by scanning the QR code to the communication device.

[0083] The communication device establishes a LoRa access whitelist for the LoRa sensor to enable the LoRa sensor to access the network.

[0084] After the WiFi sensor and LoRa sensor are registered with the network, perform the following configuration steps: The communication device sends information and network access status of the LoRa and WiFi sensors to the smart monitoring mobile terminal, which then displays a list of indoor electrical equipment and network-connected sensors. Users can check the online status of each sensor on the smart monitoring mobile terminal, and can also take photos of the sensor's specific installation location and save them.

[0085] Users can set and issue sampling cycles based on the intelligent monitoring mobile terminal, and can also issue monitoring start commands based on the intelligent monitoring mobile terminal.

[0086] If a user discovers that some sensors are missing after the monitoring equipment is running, or that adjustments need to be made to the monitored electrical equipment or sensor register, monitoring must be stopped and the device reconfigured in configuration mode. The intelligent monitoring mobile terminal does not upload or download data in configuration mode to avoid overloading.
