DETAILED DESCRIPTION

[0042] In order to make the technical problems solved by the utility model, the technical scheme adopted and the technical effects reached more clear, the technical scheme of the utility model embodiment is further described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0043] In the description of the utility model, unless explicitly defined and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements or the interaction between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0044] In the utility model, unless explicitly defined and limited, the first feature "on" or "below" the second feature can include that the first and second features are in direct contact, or the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0045] As known from the background art, as an important part of the power grid, the operation state detection of the power equipment has a crucial influence on the stability and safety of the power grid. Through regular or real-time operation state detection of the power equipment, the faults or potential problems of the equipment can be found in time, so that necessary maintenance or repair measures can be taken to prevent the expansion of faults or the occurrence of power grid accidents.

[0046] However, traditional power equipment detection devices often only provide a single type of sensor, and due to only having one or a few detection functions, such devices cannot simultaneously obtain multiple key information during the operation of power equipment, which may result in some potential faults being missed and low detection efficiency, which to some extent limits its detection ability and application range, and is usually only used to detect specific power parameters or fault modes, such as temperature, current, voltage, or vibration, etc. However, with the continuous development of the power industry and the increasing requirements for the safety of power equipment operation, a single type of sensor has been difficult to meet the comprehensive and accurate detection needs, in addition, the traditional detection device is also relatively simple in data display, which is difficult to meet the needs of modern power systems for comprehensive analysis and visual display of multi-source data.

[0047] Therefore, the present embodiment provides a multi-source data acquisition, analysis and display device, which provides an interface for more different types of sensors by adopting a partial discharge signal acquisition module and an edge computing gateway, thereby solving the problem of single type of sensor of the above-mentioned detection device.

[0048] Specifically, please refer to the accompanying drawings Figures 1-4 The multi-source data acquisition, analysis and display device mainly comprises a device box 10, which is the supporting basis of the device, and a hollow accommodating cavity 11 is formed in the inside of the device box 10 for accommodating, protecting and facilitating the carrying and transportation of the device. It can be understood that in order for the device box 10 to provide the above-mentioned related functions, it generally needs to be made of a material with relatively high strength, such as aluminum alloy stainless steel, etc. Of course, in some embodiments, the device box 10 is not limited to using wooden, plastic and other materials, and it needs to be appropriately selected according to the specific use environment and requirements.

[0049] Moreover, the specific structure of the device box 10 is not strictly limited in this embodiment, which can be but is not limited to a cube (a square), a cuboid, a cylinder or other irregular shapes.

[0050] In order to enable the structure associated with the device to be placed into the accommodation cavity 11, at least one side (such as the upper side) of the device box 10 is formed with an opening 111 communicating with the accommodation cavity 11, and it should be noted that the size of the opening 111 needs to meet the access of various components, so as to avoid the problem of interference between the components and the device box 10 during disassembly. In connection with the foregoing, the device box 10 is further provided with a box cover 12 movable relative thereto, and the box cover 12 is movable between a position close to being covered on the opening 111 and a position away from the opening 111, so as to play a role of protecting the equipment, components and circuit inside the device box 10 in the state of covering the opening 111, and when the box cover 12 opens the opening 111, it is also convenient for the operator to observe, operate and even overhaul and maintain the multi-source data acquisition, analysis and display device.

[0051] It can be understood that, like the device box 10, the box cover 12 also needs to be made of a material with high strength to ensure that it has certain supporting and protecting performance, and the material and specific manufacturing process thereof are not strictly limited and required in this embodiment.

[0052] Further, the box cover 12 is provided with a display screen 121, which in this case can be arranged on the outer surface of the box cover 12 (in the state of covering the opening 111, the display screen 121 is still exposed outside the box cover 12), or on the inner surface of the box cover 12 (in the state of opening the opening 111, the display screen 121 can be exposed outside the box cover 12). The screen on the box cover 12 is mainly used for real-time display of detection data, images or results of power equipment, which helps the operator to intuitively understand the running state and detection results of the power equipment, plays a display role in the multi-source data acquisition, analysis and display function, and improves the efficiency of overhaul and maintenance of the power equipment.

[0053] Based on the above basic structure, the multi-source data acquisition, analysis and display device further comprises an edge calculator 20. It can be understood that edge computing is a kind of distributed computing architecture, which moves the operation of application programs, data and services from the network center node to the edge node on the network logic for processing. These edge nodes are closer to user terminal devices, so as to accelerate the processing and transmission speed of data, reduce the delay, and compared with the traditional detection equipment which needs to process data through the center server, the edge calculator 20 is used as the core processing unit of the device, and since the edge calculator 20 is located near the data source (sensor), it can perform real-time processing and analysis on data, reduce the delay of data transmission, and by distributing the computing task to the edge node, the burden of the center server can be reduced, and the overall computing efficiency can be improved.

[0054] Specifically, the edge computer 20 is installed in the accommodation cavity 11 and connected with the display screen 121, so as to play a role of analyzing and displaying multi-source data for the purpose of displaying the data processed and analyzed in real time through the display screen 121.

[0055] On the basis of the above, the multi-source data acquisition, analysis and display device of the embodiment further comprises a partial discharge signal acquisition module 30 and an edge computing gateway 50.

[0056] The main functions of the partial discharge signal acquisition module 30 include signal amplification, filtering and analog-to-digital conversion (A / D conversion). Specifically, it can convert the pulse analog signal caused by the partial discharge of the power equipment into detection host information that can be easily understood by people through a series of analog and digital processing. In this example, the partial discharge signal acquisition module 30 is used to acquire UHF (Ultra High Frequency) signals, HF (High Frequency) signals and AE (Acoustic Emission) signals in power equipment (such as transformers). The three signals have different frequency ranges and characteristics, which can meet the signal acquisition conditions when the corresponding type of sensor is applied to the device.

[0057] The edge computing gateway 50 is a device that extends cloud functions to local edge devices. It enables these edge devices to quickly and autonomously respond to local events, thereby providing low-latency, low-cost, privacy-safe and locally autonomous local computing services. The edge computing gateway 50 can collect data from various devices (such as sensors) and perform preliminary processing locally, such as data cleaning, aggregation and processing. Specifically, the edge computing gateway 50 in this example is specially used to receive external sensor data in RS485 communication mode. The external sensor is connected with the edge computing gateway 50 through RS485 communication. After the data collected by the sensor is processed by the edge computing gateway 50, the edge computing gateway 50 can transmit the data to the edge computer 20 through a network cable, thereby ensuring stable transmission and management of multi-source data.

[0058] Similarly, the partial discharge signal acquisition module 30 and the edge computing gateway 50 are installed in the accommodation cavity 11, and correspondingly, a plurality of first interfaces 113 connected with the partial discharge signal acquisition module 30 are arranged at the opening 111, and the partial discharge signal acquisition module 30 is connected with the edge computer 20 through the switch 40, so that the signals received by the partial discharge signal acquisition module 30 can be collected at the switch 40 after being converted into data, and the opening 111 is also provided with a second interface 114 connected with the switch 40, and the switch 40 is used for receiving the data of the external sensor (through the second interface 114) and the partial discharge signal acquisition device in the TCP communication mode. In addition, a plurality of third interfaces 115 connected with the edge computing gateway 50 are arranged at the opening 111, and different types of sensors can be connected to the partial discharge signal acquisition module 30, the switch 40 or the edge computing gateway 50 through the first interface 113, the second interface 114 and the third interface 115, so as to realize the function of collecting multi-source data.

[0059] According to the above, it can be understood that the edge computer 20 is the core processing unit of the device, which is responsible for real-time analysis of the data received from the partial discharge signal acquisition module 30 (switch 40) and the edge computing gateway 50, and generates monitoring reports and fault warning information by pre-set algorithm for multi-source data fusion processing. In this embodiment, the first interface 113, the second interface 114 and the third interface 115 are arranged at the opening 111 of the device box 10, which can facilitate the operation of the operator when connecting different types of sensors to the device. The operator can clearly observe different types of interfaces from the opening 111, avoiding the situation of searching for the corresponding interface around the device box 10.

[0060] The multi-source data acquisition, analysis and display device is provided with an edge computer 20, a partial discharge signal acquisition module 30 and an edge computing gateway 50 on the device box 10. The partial discharge signal acquisition module 30 is connected with the edge computer 20 through a switch 40, so that the partial discharge signal acquisition module 30, the switch 40 and the edge computing gateway 50 provide a first interface 113, a second interface 114 and a third interface 115 arranged on the opening 111 of the device box 10, respectively, so that the device can flexibly access sensors of different communication modes and types, improve its expansibility, and the corresponding data transmission is more stable, solving the problems of single communication mode, sensor access limitation and the like. Different sensors may use different communication protocols and data formats. Through the above-mentioned different interfaces corresponding to the access device, the compatibility of the device is improved, which makes the operating personnel can select appropriate sensors according to actual needs without worrying about the compatibility problem with the control box. A multi-source data acquisition, analysis and display device meets the different detection needs of power equipment. In addition, with the continuous development of technology, new sensors and communication technologies are emerging. By providing interfaces of multiple communication types and sensor types, the device can more easily support new sensors and communication technologies, making the system more convenient to upgrade and maintain. It also does not need to replace the whole equipment, but only needs to replace or upgrade the corresponding interface and sensor.

[0061] As an optional implementation, please continue to refer to the accompanying Figures 1-4 The device box 10 is further provided with a cover plate 112 covering the opening 111. The cover plate 112 is fixedly connected with the device box 10 in the state of covering the opening 111, so as to prevent the cover plate 112 from easily separating from the device box 10. The cover plate 112 cooperates with the device box 10 to form a relatively stable support structure. When the box cover 12 is in an open state (the opening 111 is open), the opening 111 is still in a closed state, protecting the internal equipment from the influence of the external environment.

[0062] It can be understood that the fixation of the cover plate 112 and the device box 10 is not limited to the screw, buckle, magnetic attraction and the like.

[0063] Correspondingly, a plurality of through holes of the cover plate 112 are provided in the accommodating cavity 11. The positions of the plurality of through holes correspond to the first interface 113 and the third interface 115, respectively. The plurality of through hole structures are matched with the first interface 113 and the third interface 115, respectively, so that the through holes allow the first interface 113, the second interface 114 and the third interface 115 to pass through, and realize the connection with the equipment in the accommodating cavity 11 and the external sensor.

[0064] The structural size of the through hole matches each interface respectively, so that each interface can be fixed to the cover plate 112 after passing through the corresponding through hole, thereby playing a certain waterproof, dustproof and other effects, and in the state that the sensor is connected to the corresponding device through the corresponding interface, the sensor can also be stably erected on the cover plate 112 through the corresponding interface, thereby facilitating the disassembly of the sensor on the device and also making the connection of the sensor and the related device more stable.

[0065] In the above embodiment, the display screen 121 can be arranged on the inner surface of the box cover 12, so that in the state that the multi-source data acquisition, analysis and display device is used with the box cover 12 opened, the display can be exposed outside the device, and the data can be displayed in real time, and when the box cover 12 is closed on the device box 10, the box cover 12 can also cooperate with the device box 10 to protect the display screen 121.

[0066] In an embodiment, please refer to the accompanying drawings Figures 1-3 The device box 10 includes a support frame 14 and a partition plate 15. The support frame 14 serves as a support base of the device box 10 in this embodiment, and provides sufficient structural strength for the device box 10 to support the whole device. The cover plate 112 is correspondingly arranged on each side of the support frame 14, so that the support frame 14 is enclosed to form a closed structure, thereby playing a certain protection, moisture-proof, dust-proof and other effects.

[0067] The support frame 14 includes at least four columns 141 and a plurality of connecting rods 142. Each column 141 is arranged at each corner of the device box 10 and plays a main supporting role. The height of the column 141 determines the overall height of the device box 10, and the number of the column 141 also determines the general shape of the device box 10. For example, in the case of four columns 141, the final structure of the device box 10 can be a cube or a cuboid structure. Further, the end portions of any two adjacent columns 141 are connected by the connecting rod 142, so that the support frame 14 forms a plurality of frame openings 143 enclosed by the columns 141 and the connecting rods 142. It can be understood that the extension direction of the connecting rod 142 also needs to be determined according to the number and relative position of the columns 141. For example, in the case of four columns 141 arranged in a square or rectangular shape, each connecting rod 142 extends along the longitudinal and transverse directions and is connected to the end portions of the columns 141, thereby enhancing the horizontal and vertical stability of the support frame 14.

[0068] Each partition plate 15 is fixedly arranged on each frame opening 143, so as to enclose the support frame 14 to form the device box 10 as described above.

[0069] It should be understood that, as the supporting base of the device box 10, the support frame 14 as a whole should be made of a material with high strength (such as steel or aluminum alloy) to ensure that the frame has sufficient strength and durability, and the partition plate 15 can be made of a material with a structural strength weaker than that of the support frame 14 in addition to being made of the same material as the support frame 14, so as to reduce the production cost of the device box 10 on the basis of ensuring that the device box 10 has sufficient structural strength.

[0070] In an embodiment, the opening 111 is formed on the upper side of the device box 10. As known from the foregoing, the opening 111 can be formed by the frame opening 143 enclosed by each connecting rod 142 and the upright column 141. The opening 111 arranged on the upper side of the device box 10 is conducive to the disassembly and assembly of the equipment in the accommodation cavity 11, and also allows the operator to directly observe each interface (the first interface 113, the second interface 114, and the third interface 115), thereby facilitating the use of the operator.

[0071] On the basis of the above-mentioned scheme related to the structure of the device box 10, the edge computer 20 with a relatively regular structure and a relatively large volume is horizontally arranged at the bottom of the accommodation cavity 11. Specifically, the edge computer 20 can be erected on the partition plate 15 at the bottom of the device box 10 by means of a fixed support or the like, and is ensured to be arranged in a spaced manner with the partition plate 15, thereby ensuring good heat dissipation.

[0072] The partial discharge signal acquisition module 30 in the present embodiment includes a first acquisition module 31 and a second acquisition module 32, and the first acquisition module 31 and the second acquisition module 32 are both provided with the first interface 113 at the opening 111. The first acquisition module 31 is arranged above the edge computer 20 and forms a heat dissipation gap with the edge computer 20, and the second acquisition module 32 is arranged on one side of the first acquisition module 31. The first acquisition module 31 and the second acquisition module 32 are both in spaced cooperation with each partition plate 15, so as to ensure that the accommodation cavity 11 has sufficient heat dissipation channels, thereby facilitating the heat dissipation of each equipment. In addition, a heat dissipation gap is formed between the lower side of the second acquisition module 32 and the cavity bottom (the partition plate 15 at the bottom of the device box 10) of the accommodation cavity 11.

[0073] It can be understood that in this embodiment, the size of the edge calculator 20 is not sufficient to cover to the second acquisition module 32 below, so on the basis that the first acquisition module 31 and the second acquisition module 32 are symmetrically arranged in the accommodation cavity 11, the first acquisition module 31 needs to be arranged above the edge calculator 20, and the second acquisition module 32 is located outside the edge calculator 20. By arranging the first acquisition module 31 and the second acquisition module 32 together in this way, in addition to facilitating the disassembly and assembly of the first acquisition module 31 and the second acquisition module 32 in the accommodation cavity 11, this reasonable layout also improves the space utilization of the accommodation cavity 11, reduces the space occupation of the first acquisition module 31 and the second acquisition module 32, and provides more abundant installation space for other devices.

[0074] It should be noted that the partial discharge signal acquisition module 30 of the present embodiment adopts the first acquisition module 31 and the second acquisition module 32, which can not only realize redundant data acquisition and ensure data continuity and integrity, but also meet different data acquisition requirements. Different devices or application scenarios may have different requirements for partial discharge signal acquisition. For example, some devices may need to collect high-frequency and low-frequency signals at the same time, or need to collect signals of multiple channels. By arranging two acquisition modules, these requirements can be more flexibly met, and space is reserved for future expansion and upgrading, improving the flexibility and scalability of the system.

[0075] Further, the multi-source data acquisition, analysis and display device further comprises a direct current module, which is responsible for converting and processing the input electric energy to provide stable and required direct current power for the related devices (including but not limited to the edge calculator 20, the partial discharge signal acquisition module 30, and the edge computing gateway 50) in the accommodation cavity 11. In this embodiment, the direct current module is arranged in the accommodation cavity 11 and mounted on one of the cavity walls (one of the partitions 15 of the device box 10) of the accommodation cavity 11. Generally, the direct current module has a heat dissipation module inside, so mounting the direct current module directly on the partition 15 (and opening a corresponding heat dissipation port on the partition 15 corresponding to the heat dissipation module of the direct current module) can help the direct current module dissipate heat. At the same time, arranging it on the partition 15 can also provide more accommodation space for other devices, making the internal structure of the device more compact.

[0076] From the above, it can be understood that in order to provide stable power supply for the related devices, the direct current module is electrically connected with the edge calculator 20, the partial discharge signal acquisition module 30, the switch 40 and the edge computing gateway 50.

[0077] Further, the direct current module includes a first direct current module 16 and a second direct current module 17, and the first direct current module 16 and the second direct current module 17 can supply power for different devices and modules (such as the edge computer 20, the partial discharge signal acquisition module 30, the switch 40, and the edge computing gateway 50, etc.), which not only can realize the redundancy backup of the power supply but also can meet the power demand of different devices.

[0078] In this example, the first direct current module 16 is electrically connected with the edge computer 20, the first acquisition module 31, the switch 40, and the edge computing gateway 50, and the second direct current module 17 is electrically connected with the second acquisition module 32. The first direct current module 16 and the second direct current module 17 are both arranged on the same partition plate 15 to avoid the influence of the excessively dispersed layout on the layout and disassembly of other devices and the influence of the excessive concentration on the heat dissipation performance of the two. Specifically, the first direct current module 16 and the second direct current module 17 are arranged on the left side or the right side of the accommodating cavity 11 to facilitate the arrangement of the edge computer 20 and the partial discharge signal acquisition module 30. Figure 3 For example, the first direct current module 16 and the second direct current module 17 are arranged on the right side of the accommodating cavity 11, and both are fixed on the partition plate 15 on the right side of the device box 10. The edge computer 20 and the partial discharge signal acquisition module 30 can be arranged on the left side of the accommodating cavity 11.

[0079] Based on the above technical scheme, the first direct current module 16 and the second direct current module 17 are provided with the first heat dissipation fan 18, the side wall (the partition plate 15) of the device box 10 close to the first heat dissipation fan 18 is provided with the first air port, the first heat dissipation fan 18 is arranged on the first air port, and correspondingly, the device box 10 on the opposite side of the first heat dissipation fan 18 is provided with the second heat dissipation fan 19, and the other side wall (the other partition plate 15 opposite to the above-mentioned partition plate 15) of the device box 10 close to the second heat dissipation fan 19 is provided with the second air port 151 (not shown in the figure), and the second heat dissipation fan 19 is arranged on the second air port 151. In this example, one of the first heat dissipation fan 18 and the second heat dissipation fan 19 can be configured to blow the air outside the device box 10 into the accommodating cavity 11, and the other one of the first heat dissipation fan 18 and the second heat dissipation fan 19 can be configured to exhaust the air inside the accommodating cavity 11 outside the device box 10, so that the airflow inside the accommodating cavity 11 keeps flowing in the preset direction, thereby improving the heat dissipation efficiency inside the accommodating cavity 11.

[0080] According to the above embodiment of the partial discharge signal acquisition module 30 comprising the first acquisition module 31 and the second acquisition module 32, in the case that the device box 10 is further provided with the first heat dissipation fan 18 and the second heat dissipation fan 19, the gap between the first acquisition module 31 and the second acquisition module 32 corresponds to the arrangement of the first heat dissipation fan 18 and the second heat dissipation fan 19, so that the airflow generated by the first heat dissipation fan 18 and the second heat dissipation fan 19 in the working process can pass between the first acquisition module 31 and the second acquisition module 32, thereby facilitating the discharge of the heat dissipated upward by the edge computer 20 and the heat generated between the first acquisition module 31 and the second acquisition module 32 out of the containing cavity 11.

[0081] Further, the edge computing gateway 50 is arranged at the front side or the rear side of the containing cavity 11. It can be understood that the edge computing gateway 50 has a relatively thin structure, a relatively small size and a small amount of heat, and therefore, by arranging the edge computing gateway 50 at the front side or the rear side of the containing cavity 11, a safe spacing range can be formed with other devices (especially on the basis of the above layout structure), avoiding the influence of the heat dissipated by other devices on the edge computing gateway 50, and also making the edge computing gateway 50 and other devices more easily disassembled.

[0082] As an optional embodiment, as shown in Figures 1-2 , Figure 4 The wireless communication module 122 is further arranged on the box cover 12, and the wireless communication module 122 is connected with the edge computer 20, so that the data can be transmitted to external devices through the wireless communication module 122 in addition to being displayed in real time on the display screen 121, and the analysis result can be wirelessly transmitted to a remote terminal, realizing remote monitoring and management of the data, and facilitating the operation personnel to understand the operation of the power equipment at any time.

[0083] Moreover, arranging the wireless communication module 122 on the box cover 12 makes the box cover 12 exposed to the external environment relative to the device box 10, which is also conducive to reducing the signal interference of the wireless communication module 122 and reducing the data transmission delay to a certain extent.

[0084] From the above content, it can be understood that the multi-source data acquisition, analysis and display device provides corresponding access positions for different types of sensors through the arrangement of the first interface 113, the second interface 114 and the third interface 115. In the present embodiment, the sensors include but are not limited to the current sensor 100, the temperature sensor 300, the humidity sensor 200, the noise sensor 400, the vibration sensor 500, the video sensor 600, the oil chromatograph sensor 700, the radio wave sensor 800, the electromagnetic wave signal sensor 900, the contact acoustic emission signal sensor 1000 and the non-contact acoustic emission signal sensor 2000.

[0085] Taking sensors including current sensor 100, temperature sensor 300, humidity sensor 200, noise sensor 400, vibration sensor 500, video sensor 600, oil chromatography sensor 700, radio wave sensor 800, electromagnetic wave signal sensor 900, contact acoustic emission signal sensor 1000, and non-contact acoustic emission signal sensor 2000 as an example, such as... Figure 4 As shown, the radio wave sensor 800, electromagnetic wave signal sensor 900, contact acoustic emission signal sensor 1000, and non-contact acoustic emission signal sensor 2000 can be connected to the partial discharge signal acquisition module through the first interface 113. The video sensor 600 and the oil chromatography sensor 700 can be connected to the switch 40 through the second interface 114. The current sensor 100, temperature sensor 300, humidity sensor 200, noise sensor 400, and vibration sensor 500 can all be connected to the edge computing gateway 50 through the third interface 115.
