Description

A 3D visualization monitoring system for railway traction substations Technical Field

[0002] This invention belongs to the field of electrical monitoring technology, specifically a three-dimensional visualization monitoring system for railway traction substations. Background Technology

[0003] Traction substations are power supply facilities that convert high-voltage electrical energy into voltage suitable for electric locomotives and distribute it to the overhead contact line or contact rail. Their core equipment is the traction transformer, which is divided into DC and AC types: the former outputs DC power through step-down rectification, while the latter converts it into single-phase or three-phase AC power. Based on power supply mode, they are divided into centralized power supply (independently undertaking the power supply arm's tasks) and distributed power supply (capable of providing cross-regional support), with centralized power supply being the mainstream method.

[0004] Traction substations must meet the voltage drop limits of the traction network and are often built in conjunction with step-down substations to save costs. A typical traction substation uses dual 220 kV incoming power supplies and is equipped with intelligent sensing, ventilation, and settlement monitoring systems to achieve unmanned operation and holistic maintenance.

[0005] For visual monitoring of various electrical equipment inside traction substations, manual inspections are usually combined with fixed visual monitoring equipment, which is labor-intensive. In some traction substations that are relatively remote and difficult to deploy personnel for manual inspections, a failure of the fixed monitoring equipment will create blind spots in the monitoring, making it difficult to fully monitor the safe operation of the entire traction substation and thus compromising the safety of the traction substation.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: As shown in Figures 1-5 of the accompanying drawings, this application proposes a three-dimensional visualization monitoring system for railway traction substations, including a data acquisition unit, a data processing unit, and a data feedback interaction unit. The data acquisition unit is used to collect the working status data of electrical equipment in the railway traction substation. The data acquisition unit includes a fixed acquisition module and a mobile acquisition module. The fixed acquisition module includes an information acquisition device 11 installed on the top of a fixed rod 1. The mobile acquisition module includes a mobile trolley 2. An installation cylinder 22 is installed in the installation groove 21 at the rear of the mobile trolley 2. An installation block 221 is slidably installed inside the installation cylinder 22. An information acquisition sensor is configured on the installation block 221, including an image sensor, a temperature and humidity sensor, and a smoke sensor. A sealing plate 222 is installed at the top of the installation block 221 corresponding to the top of the installation cylinder 22. The installation block 221 is connected to the output end of the telescopic device at the bottom of the installation cylinder 22.

[0022] Specific workflow: To ensure the normal and safe operation of railway traction substations and achieve automated monitoring, a fixed data acquisition module is installed. Information acquisition devices 11 mounted on fixed pole 1 monitor nearby electrical equipment also located on pole 1. These devices include image sensors such as cameras, as well as temperature, humidity, and smoke monitoring sensors. This allows for real-time monitoring of the working environment, enabling timely detection and feedback of any abnormalities in the electrical equipment's working environment, thus preventing the escalation of electrical accidents and reducing personal and property losses. Additionally, the data acquisition unit also includes various types of voltage and current sensors and energy meters. The equipment, such as meters, is arranged on various electrical equipment in the railway traction substation, maintaining electrical connection and feeding back various electrical parameters to the data processing unit in real time. Furthermore, the mobile acquisition module's mobile trolley 2, following a predetermined route, patrols various locations within the railway traction substation in turn. Various monitoring sensors mounted on the mobile trolley 2 can collect information on the environmental conditions around the moving route. Specifically, during movement, the mobile trolley 2 can activate a telescopic device located inside the mounting cylinder 22, pushing the internal mounting block 221 upwards, thereby causing the image sensors mounted on the mounting block 221 to leave the mounting cylinder 22. 2. The upper side captures images of the surrounding environment and collects environmental data such as temperature and humidity. In adverse weather conditions, to ensure the safety of the monitoring sensors, the mounting block 221 can be retracted into the mounting cylinder 22, with the top sealing plate 222 maintaining the seal on the top opening of the mounting cylinder 22. This ensures that the various monitoring sensors mounted on the mounting block 221 are protected within the enclosed environment of the mounting cylinder 22, preventing external dust, impurities, and other adverse factors from affecting the sensors, ensuring their lifespan, and improving their adaptability to various working environments. Furthermore, the mobile trolley 2 collects information from blind spots that are difficult to cover by the fixed acquisition module, combining static and dynamic approaches. Through mutual verification, comprehensive coverage and full monitoring of railway traction substations are achieved, and the safety and reliability of collected information are improved. Moreover, when the information collection equipment 11 corresponding to the fixed collection module in some areas fails, the mobile trolley 2 can be controlled to go to the faulty area as a supplement, filling the gaps in the monitoring network and improving the risk resistance of the entire railway traction substation monitoring system. The data processing unit includes a data preprocessing module, a data fusion module, a data storage module, and a data analysis module. The data preprocessing module is used to filter, denoise, and complete the collected working environment data and electrical parameters and other raw data, and remove abnormal data to ensure data accuracy.Subsequently, the data fusion module binds electrical equipment-related data, electrical equipment operating environment data, and spatial location data to establish a "data-equipment-location" mapping relationship. This allows the fault diagnosis algorithm in the data analysis module to quickly locate the corresponding electrical equipment and its spatial location when it identifies abnormal data and triggers an alarm. Real-time feedback is then sent to the relevant maintenance personnel via the data feedback interaction unit's communication module, reminding them to take appropriate measures according to the contingency plan, thus reducing the occurrence of electrical accidents. Daily monitoring data of the electrical equipment can be compiled into a work log, including records of handling abnormal situations, and stored in the data storage module for record-keeping, providing data support for subsequent equipment maintenance and potential accident investigations.

[0023] Example 2: Based on Example 1, the bottom of the mounting cylinder 22 is connected to the magnetic attraction limiting device on the inner wall of the mounting groove 21. A vertically extending slide groove 12 is provided on the surface of the fixed rod 1. An adjustment block 13 is slidably provided at the bottom of the slide groove 12. A fixing hook block 14 is provided on the adjustment block 13. A connecting block 23 is provided at the part of the mounting cylinder 22 near the fixing hook block 14. A connecting groove 231 is provided on the connecting block 23 at the part corresponding to the fixing hook block 14. Specific workflow: Based on the specific workflow in Example 1, for the information acquisition device 11 on the fixed rod 1 that has a local malfunction, in order to conduct a nearby investigation and make up for the monitoring loophole, the moving trolley 2 is controlled to move to the fixed rod that has the malfunction. 1. On the lower side, the mounting block 221 extends into the mounting cylinder 22, enabling the configured information acquisition sensor to replace the malfunctioning information acquisition device 11. Since the information acquisition device 11 on the fixed rod 1 is located at a higher position, it has a wider monitoring field of view, thus further eliminating monitoring blind spots. The mounting cylinder 22 can be controlled to separate from the mobile trolley 2 and raised to the original location of the information acquisition device 11, replacing the malfunctioning device 11 and performing its corresponding monitoring function. Specifically, the mounting cylinder 22 and the mounting slot 21 of the mobile trolley 2 are separate units, with the mounting slot 21 being magnetically attached to the inner wall of the mounting slot 21. To separate the components, firstly, the moving trolley 2 needs to be moved backward towards the adjusting block 13 on the lower side of the slide 12, so that the fixing hook 14 on the adjusting block 13 engages with the connecting groove 231 on the mounting cylinder 22, thus achieving the engagement between the fixing hook 14 and the mounting cylinder 22. Then, the magnetic attraction device is turned off, causing the mounting cylinder 22 to separate from the mounting groove 21. At this time, the adjusting block 13 is controlled to move the mounting cylinder 22 up along the slide 12 to a position close to the top of the information acquisition device 11 on the fixed rod 1. This allows for close observation of the appearance of the abnormal information acquisition device 11, facilitating remote observation by maintenance personnel to determine the specific situation of the abnormality. Furthermore, the mounting cylinder 22, now at the predetermined position, allows the fixing hook 14 on the fixed rod 1 to engage with the connecting groove 231 on the mounting cylinder 22. The information acquisition sensor configured in the mounting block 221 can replace the original abnormal information acquisition device 11 and function normally as a fixed node in the entire substation monitoring network to ensure the normal operation of the substation. Regarding the specific scheme for how to realize the vertical movement of the adjustment block 13 along the slide 12, there are various possible technical solutions. Any solution that can meet the above requirements can be applied to this application. This embodiment provides a possible technical solution, which can use the existing electric slide rail and electric slider technology. The part where the adjustment block 13 slides into the slide 12 is set as an electric slider. The vertical position is adjusted in the vertical direction under the action of an external controller along the vertical slide 12 built using electric slide rail technology.

[0024] Example 3: Based on Example 2, the fixed rod 1 is hollow to form an adjustment cavity. A traction rope 15 is installed inside the adjustment cavity. The traction rope 15 can be made of elastic, high-strength non-metallic insulating material. One end of the traction rope 15 passes through the opening at the top of the fixed rod 1 and extends downward to connect with the top of the adjustment block 13. The other end of the traction rope 15 extends out from the opening at the bottom of the fixed rod 1 and connects with the bottom of the adjustment block 13. A drive roller 151 is installed inside the adjustment cavity. The drive roller 151 is connected to the output end of the drive device. The drive device can be a motor drive device. The traction rope 15 passes around the drive roller 151 and is in close contact with the drive roller 151.

[0025] Specific workflow: Based on the specific workflow in Embodiment 2, and based on the cooperation relationship between the adjustment block 13 and the slide 12, when the fixed hook block 14 on the adjustment block 13 is engaged with the connecting groove 231 on the mounting cylinder 22, the drive device connected to the drive roller 151 can be started, driving the annular traction rope 15 to rotate, thereby pulling the adjustment block 13 located in the slide 12 to move upward along the slide 12 until the mounting cylinder 22 moves to a predetermined position close to the information acquisition device 11. At this time, the drive device is turned off and the traction rope 15 is locked, so that the mounting cylinder 22 in the moving position is kept in a limited position by the pull of the traction rope 15. This can reduce the workload of the electric slide rail corresponding to the slide 12, improve the redundancy of the entire traction lifting system, and ensure the stability of the adjustment block 13 when performing monitoring work at a high position.

[0026] Example 4: Based on Example 3, the adjusting block 13 is provided with a storage groove 131, and the fixing hook block 14 is connected to the output end of the propulsion device provided on the inner wall of the storage groove 131. The end of the fixing hook block 14 is bent upward, and the inner wall of the connecting groove 231 extends upward. A connecting line 16 is provided inside the fixing hook block 14, and a connecting interface 161 is provided at the end of the fixing hook block 14. A storage connector 232 is provided on the inner wall of the connecting groove 231, and the storage connector 232 is connected to the data storage device inside the mounting cylinder 22. A transmission interface 111 is provided at the bottom of the information acquisition device 11, and a connecting part is provided on the fixing hook block 14 at the part corresponding to the transmission interface 111. Connector 162; Specific working process: Based on the specific working process in Embodiment 3, the information acquisition device 11 located on the upper side of the fixed rod 1 can transmit the collected information to the data processing unit through wireless communication technology to achieve information aggregation; however, when the information acquisition device 11 malfunctions, it may lose contact. In this case, a wired connection should be established nearby to check the working status of the information acquisition device 11 and receive the information already collected and stored by the information acquisition device 11; to ensure connection safety, a connecting line 16 is configured inside the fixed hook block 14, and an independent power supply and connection safety are also provided in the middle of the connecting line 16. The detection device is pre-connected to the information acquisition device 11 to check the safety of the connection before transmitting the information stored in the information acquisition device 11 to the information storage device inside the mounting cylinder 22. Specifically, to ensure the safety of the connection interface 161 and the connection joint 162 on the fixing hook block 14, the fixing hook block 14 is retracted into the storage groove 131 before the mounting cylinder 22 needs to be fixed. When the mounting cylinder 22 needs to be docked, the moving trolley 2 needs to be controlled to move along a predetermined route to approach the opening of the storage groove 131. Then, the propulsion device is started to drive the fixing hook block 14 out of the storage groove 131 and into the mounting groove 21, and it is located under the connection groove 231. Position, then control the adjustment block 13 to move upward, so that the end of the fixed hook block 14 is embedded in the connecting groove 231, and the connection interface 161 provided at the end of the fixed hook block 14 is combined with the storage connector 232 provided on the inner wall of the connecting groove 231 to achieve electrical connection. Then the adjustment block 13 continues to move upward, driving the fixed hook block 14 to approach and contact the bottom of the information acquisition device 11, so that the connection connector 162 on the fixed hook block 14 is combined with the transmission interface 111 at the bottom of the information acquisition device 11. At this time, the connecting line 16 inside the fixed hook block 14 acts as a relay to connect the information storage device inside the mounting cylinder 22 and the information acquisition device 11.To ensure safety, the connection safety detection device configured on the internal connecting line 16 of the fixed hook block 14 can be pre-connected to the information acquisition device 11. After confirming that the electrical connection between the device and the information acquisition device 11 is normal and safe using configured current and voltage sensors, the connection interface 161 connected to the mounting cylinder 22 is then connected. This allows the information storage device configured on the mounting cylinder 22 to access the information acquisition device 11 and transmit the operating status information of the information acquisition device 11, as well as previously collected information, to the information storage device. Subsequently, the mounting cylinder 22 can be controlled to replace the information acquisition device 11 and operate normally. The received information is transmitted to the maintenance personnel via a properly functioning communication device on the mounting cylinder 22. Alternatively, the adjusting block 13 can be controlled to reset the mounting cylinder 22 back to the mobile trolley 2, allowing the mobile trolley 2 to return to the maintenance personnel's location. This facilitates the maintenance personnel in directly retrieving the information storage device and analyzing the information within. This achieves safe transfer and transmission of information, avoiding potential loss of information during wireless transmission.

[0027] Example 5: Based on Example 4, a shielding cylinder 112 is provided at the bottom of the information acquisition device 11 around the transmission interface 111. The shielding cylinder 112 can be made of insulating non-metallic material. The top of the shielding cylinder 112 is slidably embedded into the annular groove at the bottom of the information acquisition device 11 and connected to the elastic element on the inner wall of the annular groove. The elastic element can be a spring. A connection hole 113 is provided at the bottom of the shielding cylinder 112 corresponding to the transmission interface 111. The area surrounded by the shielding cylinder 112 is a protective zone. An annular cooling cavity 114 is provided on the inner wall of the bottom of the information acquisition device 11 around the transmission interface 111. The cooling cavity 114 is connected to the air outlet of the cooling fan inside the information acquisition device 11. The cooling fan is a conventionally configured cooling device inside the information acquisition device 11. The bottom opening of the transmission interface 111 is conical, and an annular closed groove 115 is evenly provided on the inner wall of the conical part. An air outlet 116 is provided on the inner wall of the closed groove 115, and the air outlet 116 is connected to the interior of the cooling cavity 114.

[0028] Specific workflow: Based on the specific workflow in Embodiment 4, a shielding cylinder 112 is provided at the bottom of the transmission interface 111 located at the bottom of the information acquisition device 11, forming a seal at the bottom opening of the transmission interface 111. This can prevent external moisture and impurities from adversely affecting the transmission interface 111. Furthermore, a humidity sensor can be installed in the protective area inside the shielding cylinder 112. When excessive external humidity is detected, the control valve in the cooling fan outlet and cooling chamber 114 can be opened, allowing the hot airflow generated after the information acquisition device 11 cools down to enter the bottom opening of the transmission interface 111 and fill the protective area, carrying away moisture, dust, and impurities that may penetrate into the protective area and threaten the transmission interface 111, ensuring the safety of the protective area. Further, when the fixing hook block 14 moves upward to the information acquisition device 11, the connection interface 16 located at the corresponding position on the fixing hook block 14... 1. The connector 162 moves upward through the corresponding connection hole 113 on the shielding cylinder 112 and is pressed upward until the connector 162 is fully embedded in the transmission interface 111, thus achieving an electrical connection. During the electrical connection process, the joint between the connector 162 and the transmission interface 111 is within the coverage area of ​​the shielding cylinder 112, preventing external dust, impurities, and moisture from affecting the normal connection between the connector 162 and the transmission interface 111, ensuring the normal operation of the information transmission process. During the connection process, if the temperature of the connection part is detected to be too high, a cooling airflow can be sent into the cooling chamber 114. The cooling chamber 114 surrounds the connection part and transfers the heat of the connection part to the flowing cooling airflow. The cooling airflow permeates outward along the gap between the connector 162 and the connection hole 113, forming an outward flow trend, further ensuring the safety and stability of the electrical connection.

[0029] Example 6: Based on Example 5, a sealing membrane 117 is provided on the inner wall of the connecting hole 113, and a through hole is provided in the middle of the sealing membrane 117. The cross-section of the sealing membrane 117 is a continuous W shape. A sealing protrusion 141 is provided on the fixed hook block 14 at the bottom of the connecting joint 162, and an annular sealing block 142 is provided on the surface of the sealing protrusion 141. Specific working process: Based on the specific working process in Example 5, by providing the sealing membrane 117, and the diameter of the through hole in the middle of the sealing membrane 117 is smaller than the diameter of the end of the connecting joint 162, the sealing performance of the connecting hole 113 can be effectively improved. This ensures the safety of the transmission interface 111 before the fixed hook block 14 moves upward. When the connecting joint 162 moves upward with the fixed hook block 14, the end of the connecting joint 162 aligns with the through hole and squeezes the sealing membrane 117, causing the sealing membrane 117 to deform elastically. The connecting joint 162 penetrates the through hole and is inserted upward into the transmission interface 111. The transmission interface 112... The bottom opening has an annular sealing groove 115 evenly distributed on its inner wall. The surface of the sealing membrane 117 contacts the sealing groove 115. The continuously curved protruding part of the sealing membrane 117 is embedded in the sealing groove 115. At the same time, the sealing protrusion 141 at the bottom of the connecting joint 162 pushes up the sealing membrane 117, causing the sealing membrane 117 to elastically deform and fill the continuously curved gap between the sealing protrusion 141 and the sealing groove 115. The continuously curved gap can effectively prevent the penetration of external moisture. The sealing membrane 117 can be hollow inside and filled with dry particles. The upper and lower surfaces of the sealing membrane 117 can be provided with exchange holes. The pore size of the exchange holes is smaller than the particle size of the dry particles. This allows the hollow area inside the sealing membrane 117 located in the continuously curved gap between the sealing groove 115 and the sealing protrusion 141 to exchange airflow with the gap area. The dry particles filled inside absorb the moisture that has penetrated into the gap area, ensuring the connection safety between the transmission interface 111 and the connecting joint 162. The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
