Description

Technical Field

[0001] This invention relates to the field of smart grid equipment technology, specifically to a multi-source data grid fusion terminal. Background Technology

[0002] Multi-source data power grid fusion terminals, as core monitoring and edge computing devices on the distribution transformer side, are widely used in urban and rural power distribution networks, industrial park distribution transformer areas, outdoor box-type substations, and other scenarios. They can collect power grid operation data, local equipment information, and environmental parameters in real time, and also undertake functions such as remote communication, edge processing, and fault monitoring. They are key terminal devices for ensuring the stable operation of the power grid and realizing intelligent operation and maintenance.

[0003] Existing power grid integration terminals mostly use fixed ventilation holes or simple louver structures for heat dissipation, lacking active adjustment and automatic protection capabilities. Insufficient ventilation in high-temperature environments can easily lead to overheating and system crashes of internal modules. In humid and dusty environments, condensation and short circuits are prone to occur, making them unsuitable for complex outdoor temperature and humidity conditions and harsh working conditions.

[0004] To address this, we have developed a new type of multi-source data power grid fusion terminal. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a multi-source data power grid fusion terminal.

[0006] The technical solution adopted to solve the above technical problems is: A multi-source data grid fusion terminal includes a housing, with ventilation components installed on both outer sides of the housing, and a temperature and humidity probe fixedly installed on one outer side of the housing. The ventilation assembly includes a mounting frame fixedly installed on the outside of the housing. Isolation nets are fixedly installed on both the end face and bottom face of the mounting frame facing the housing. The mounting frame is connected to the inside of the housing. Several guide plates are rotatably installed in a linear array inside the mounting frame. A switch assembly is installed on one side of the mounting frame. The switch assembly includes a guide rail fixedly mounted on the outer side of the housing, a connecting plate slidably mounted on the guide rail, and a plurality of Z-shaped guide grooves opened on the side of the connecting plate away from the guide rail, with an L-shaped rod slidably fitted inside the Z-shaped guide grooves; The mounting frame has several rotating shafts arranged in a linear array on one side. One end of each rotating shaft passes through the side wall of the mounting frame and is fixedly connected to the side of the corresponding guide plate. The other end of the rotating shaft is fixedly connected to a spur gear. A rack is meshed with the circumferential side of the spur gear. A connecting groove is provided on one side of the rack. The end of the L-shaped rod away from the connecting plate is slidably engaged with the connecting groove on the corresponding rack.

[0007] Preferably, a plurality of guide seats are fixedly installed in a linear array on the outer side of the housing, and the L-shaped rod slides through and engages with the corresponding guide seat; A first support base is fixedly installed on the outer side of the housing, and a first electric push rod is fixedly installed on one side of the first support base. The output end of the first electric push rod is fixedly connected to the connecting plate. The Z-shaped guide groove includes a first slide groove, and the two ends of the first slide groove are respectively connected to a parallel second slide groove and a third slide groove. The connection between the first slide groove and the second and third slide grooves is chamfered. The length of two adjacent second slide grooves increases linearly.

[0008] Preferably, a slot is provided through one end of the rack, and a first hook is fixedly connected to the other end of the rack, with the first hooks of two adjacent racks engaging with the slot; Two symmetrical positioning plates are fixedly installed on the outer side of the housing, and the two outermost racks slide in cooperation with the two positioning plates respectively.

[0009] Preferably, a second support base is fixedly installed on the outer side of the housing, a second electric push rod is fixedly installed on one side of the second support base, and a second buckle is fixedly installed on the output end of the second electric push rod. The second buckle is aligned with the slot on the outermost rack.

[0010] Preferably, a sleeve plate is fixedly installed on the side of the rack away from the spur gear, a connecting plate is slidably fitted inside the sleeve plate, and a connecting rod is rotatably installed on the side of the connecting plate away from the sleeve plate; Two symmetrical guide strips are fixedly connected to one side of the guide plate, and a brush is slidably installed on both guide strips. The end of the connecting rod away from the connecting plate is hinged to the brush side, and a stop bar is fixedly installed between the two guide strips.

[0011] Preferably, a through groove is provided on one side wall of the mounting frame, and the connecting plate is slidably engaged with the through groove; An isolation cover is fixedly installed on the outer side of the housing, and the switch assembly is located inside the isolation cover.

[0012] The above technical solution can automatically adjust the number of deflectors and their tilt angle in real time according to the external temperature and humidity, so as to achieve graded ventilation and heat dissipation and moisture protection. The switch assembly uses electric push rods, Z-shaped grooves and rack and pinion gears to achieve precise opening and closing and synchronous rotation of the deflectors in groups. At the same time, the brush automatically cleans the dust accumulated on the deflectors, improving the terminal heat dissipation efficiency and outdoor protection capabilities.

[0013] Preferably, a display panel, a control room flip cover, and a bottom end cover are sequentially fixedly installed on the front of the housing along the vertical direction; The main information control module, local communication module, remote communication module, crash detection and restart module, and terminal block are fixedly installed vertically inside the housing.

[0014] Preferably, the crash detection and restart module includes a watchdog unit, a backup power supply unit, a switch execution unit, and a delay control unit; The watchdog unit is provided with a signal input terminal and a status output terminal, and the signal input terminal is electrically connected to the signal output terminal of the main information control module.

[0015] Preferably, the backup power unit is provided with a charging end and a discharging end. The charging end is electrically connected to the external main power supply, and the discharging end is electrically connected to the power supply end of the watchdog unit, the control end of the switch execution unit, and the power supply end of the delay control unit. The switch execution unit is provided with a control signal input terminal, a power input terminal and a power output terminal. The power input terminal is electrically connected to the main power supply, the power output terminal is electrically connected to the power supply terminal of the main information control module, and the control signal input terminal is electrically connected to the output terminal of the delay control unit. The delay control unit is provided with a trigger signal input terminal and a command output terminal, and the trigger signal input terminal is electrically connected to the status output terminal of the watchdog unit.

[0016] Through the above technical solution, the terminal is equipped with an independent hardware crash detection and restart unit to monitor the main module's operating status in real time. Once a crash occurs, it automatically triggers a hard reset action of power-off and delayed power-on, without the need for manual or remote intervention. This effectively solves the problems of high-temperature crashes and program freezes, ensuring the stable and reliable operation of the terminal.

[0017] The beneficial effects of this invention are as follows: This invention arranges ventilation components symmetrically on both sides of the housing. Temperature and humidity probes collect external temperature and humidity data in real time and feed them back to the main control module. Based on environmental parameters, the linkage switch components realize adaptive and graded adjustment of the number of deflector openings and the tilt angle. When the temperature is high, it is fully open for strong convection heat dissipation; when it is humid, it is opened at a small degree for moisture prevention; and when it rains, it is fully closed for sealing. It can accurately adapt to the changing outdoor working conditions and avoid the problems of insufficient heat dissipation or short circuit due to moisture in fixed ventilation structures. This invention drives the connecting plate to slide through the first electric push rod in the switch assembly. The segmented trajectory of the Z-shaped guide groove drives the L-shaped rod to move sequentially, realizing the opening and closing of the guide plate in groups. Then, the second electric push rod links the rack and pinion gear to finely adjust the angle. The operation process is smooth and orderly with high adjustment accuracy. At the same time, when the rack moves, it drives the brush to reciprocate to clean the surface of the guide plate, which can automatically remove accumulated dust, continuously maintain a high-efficiency ventilation state, and reduce the frequency of manual maintenance. This invention configures an independent crash detection and restart module. The watchdog unit continuously receives the main module's working signals. Once a crash occurs due to high temperature, a fault determination is immediately triggered. After a stable delay by the delay unit, the control execution unit cuts off the main power supply, discharges fully, and then restores power, completing a hard reset. No manual or remote intervention is required, and operation can be automatically restored. This fundamentally solves the problems of high temperature crashes and operational freezes, and significantly improves the long-term online stability of the terminal. Attached Figure Description

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. Specific Implementation Example 1: like Figure 1 - Figure 8 As shown, this embodiment of the invention provides a multi-source data power grid fusion terminal, including a housing 1. Ventilation components 2 are installed on both outer sides of the housing 1. A temperature and humidity probe 3 is fixedly installed on one outer side of the housing 1. Here, the temperature and humidity probe 3 is used to collect the temperature and humidity data of the external environment of the housing 1 in real time, providing an environmental basis for the adjustment of the ventilation components 2. The ventilation components 2 are symmetrically arranged on both sides of the housing 1, which can form a double-sided convection ventilation path. Together with the internal fan of the housing 1, the air exchange is realized, meeting the heat dissipation and moisture prevention requirements in different environments. The ventilation assembly 2 includes a mounting frame 4 fixedly installed on the outside of the housing 1. Isolation nets are fixedly installed on the end face and bottom face of the mounting frame 4 facing the housing 1 to block mosquitoes from entering the interior of the housing 1. The mounting frame 4 is connected to the interior of the housing 1. Several guide plates 5 are mounted in a linear array inside the mounting frame 4. A switch assembly 6 is installed on one side of the mounting frame 4. These guide plates 5 can rotate around their own axis and adjust the opening of the ventilation opening by changing their tilt angle. The switch assembly 6 is used to drive these guide plates 5 to rotate synchronously or in groups to achieve graded control of ventilation volume.

[0022] Specifically, the switch assembly 6 includes a guide rail 7 fixedly installed on the outer side of the housing 1, a connecting plate 8 slidably installed on the guide rail 7, and a plurality of Z-shaped guide grooves 9 opened on the side of the connecting plate 8 away from the guide rail 7. An L-shaped rod 10 is slidably fitted inside the Z-shaped guide groove 9. When the connecting plate 8 slides linearly along the guide rail 7, the trajectory change of the Z-shaped guide groove 9 will push the L-shaped rod 10 to produce lateral displacement. The segmented structure of the Z-shaped guide groove 9 can realize the step-by-step action of the L-shaped rod 10 under different strokes, providing a displacement conversion basis for the group control of the flow guide plate 5. A number of rotating shafts 11 are arranged in a linear array and rotate through one side of the mounting frame 4. One end of each rotating shaft 11 passes through the side wall of the mounting frame 4 and is fixedly connected to the side of the corresponding guide plate 5. The other end of each rotating shaft 11 is fixedly connected to a spur gear 12. A rack 13 meshes with the circumference of the spur gear 12. A connecting groove 14 is provided on one side of the rack 13. The end of the L-shaped rod 10 away from the connecting plate 8 slides with the connecting groove 14 on the corresponding rack 13. Two symmetrical positioning plates 23 are fixedly installed on the outer side of the housing 1. The two outermost racks 13 are... Do not slide with the two positioning plates 23; when the L-shaped rod 10 moves toward the mounting frame 4, it will drive the corresponding rack 13 to move synchronously in a straight line through the connecting slide groove 14, causing the corresponding rack 13 to break away from the restriction of the positioning plate 23. At the same time, by driving the rack 13 to move linearly along its own length, it can drive the spur gear 12 meshing with it to rotate around its own axis. The spur gear 12 drives the guide plate 5 to rotate synchronously around the rotating shaft 11 through the rotating shaft 11, thereby changing the tilt angle of the corresponding guide plate 5 and realizing the adjustment of the ventilation opening angle. A number of guide seats 15 are fixedly installed in a linear array on the outer side of the housing 1. The L-shaped rod 10 slides through and engages with the corresponding guide seat 15. In this way, the guide seat 15 restricts the movement direction of the L-shaped rod 10, prevents it from sliding and deviating, ensures that the L-shaped rod 10 moves smoothly, and provides stable transmission for the grouping selection of the guide plate 5. A first support base 16 is fixedly installed on the outer side of the housing 1. A first electric push rod 17 is fixedly installed on one side of the first support base 16. The output end of the first electric push rod 17 is fixedly connected to the connecting plate 8. The connecting plate 8 is driven to slide by the first electric push rod 17, so as to control the extension and retraction stroke of the first electric push rod 17 to change the sliding distance of the connecting plate 8, thereby controlling the number of L-shaped rods 10 participating in the action and realizing the graded selection of the number of opening of the guide plate 5. The Z-shaped guide groove 9 includes a first slide groove 18, with parallel second slide grooves 19 and third slide grooves 20 connected to both ends of the first slide groove 18. The connection between the first slide groove 18 and the second slide grooves 19 and third slide grooves 20 is chamfered. The lengths of two adjacent second slide grooves 19 increase linearly. When the connecting plate 8 slides linearly along the guide rail 7, it drives the Z-shaped guide groove 9 to move synchronously. The L-shaped rod 10 can only slide laterally in a fixed direction under the restriction of the guide seat 15. Therefore, the L-shaped rod 10 will go through three stages in the Z-shaped guide groove 9: sliding with the groove in the second slide groove 19, being pushed outward by the groove in the first slide groove 18, and sliding with the groove in the third slide groove 20. The L-shaped rod 10 is initially located in the second slide groove 19. At this time, the connecting plate 8 slides slightly, and the L-shaped rod 10 slides only in the same direction as the second slide groove 19 without moving laterally. The corresponding guide plate 5 remains closed. As the connecting plate 8 continues to slide, the L-shaped rod 10 slides into the first slide groove 18. Driven by the inclined trajectory of the first slide groove 18, the L-shaped rod 10 is forced to move laterally outward, pushing the corresponding rack 13 to disengage from the positioning plate 23 and releasing the rotation lock of the guide plate 5. After the connecting plate 8 slides further, the L-shaped rod 10 slides into the third slide groove 20. At this time, the L-shaped rod 10 slides again in the same direction as the third slide groove 20 without moving laterally. The guide plate 5 is in an adjustable state. The chamfering process allows the L-shaped rod 10 to smoothly switch at the transition between the second slide groove 19, the first slide groove 18, and the third slide groove 20, reducing frictional resistance and preventing jamming. The length of two adjacent second slide grooves 19 increases linearly, so that the strokes of each L-shaped rod 10 entering the first slide groove 18 are staggered. Each time the connecting plate 8 slides a fixed distance, it can only push one L-shaped rod 10 into the first slide groove 18 and move it outward. The subsequent L-shaped rods 10 are triggered in sequence, so that the guide plate 5 can be opened gradually from single to multiple pieces and from few to many pieces, accurately matching the ventilation volume adjustment needs under different working conditions. One end of the rack 13 has a slot 21 through it, and the other end of the rack 13 is fixedly connected to a first hook 22. The first hooks 22 of two adjacent racks 13 are inserted into the slots 21 and cooperate with each other. The adjacent racks 13 can be linked by the first hooks 22 and the slots 21. The movement of these linked racks 13 in their length direction is synchronous. A second support base 24 is fixedly installed on the outer side of the housing 1. A second electric push rod 25 is fixedly installed on one side of the second support base 24. A second buckle 26 is fixedly installed on the output end of the second electric push rod 25. The second buckle 26 is aligned with the slot 21 on the outermost rack 13. When the guide plate 5 is selected by the first electric push rod 17, the outermost rack 13 is the first to disengage from the restriction area between the two positioning plates 23. Simultaneously, after the L-shaped rod 10 moves the rack 13 into position, refer to... Figure 5It can be seen that the second latch 26, which is at the initial position of the second electric push rod 25, has been locked into the slot 21 of the rack 13. After the set number of guide plates 5 are selected, the second electric push rod 25 drives the selected rack 13 to move along its length direction through the second latch 26, so that the rack 13 drives the spur gear 12 meshing with it to rotate around its own axis. The spur gear 12 drives the guide plate 5 to rotate synchronously around the rotating shaft 11 through the rotating shaft 11, thereby changing the tilt angle of the corresponding guide plate 5. A sleeve plate 27 is fixedly installed on the side of the rack 13 away from the spur gear 12. A connecting plate 28 is slidably fitted inside the sleeve plate 27. A connecting rod 29 is rotatably installed on the side of the connecting plate 28 away from the sleeve plate 27. Two symmetrical guide bars 30 are fixedly connected to one side of the guide plate 5. A brush 31 is slidably installed on both guide bars 30. The end of the connecting rod 29 away from the connecting plate 28 is hinged to one side of the brush 31. A stop bar 32 is fixedly installed between the two guide bars 30. A through groove 33 is opened through one side wall of the mounting frame 4. The connecting plate 28 is slidably fitted with the through groove 33. When the L-shaped rod 10 drives the corresponding rack 13 to move towards the mounting frame 4, the rack 13 will drive the sleeve 27 to move synchronously. At this time, the sleeve 27 moves relative to the connecting plate 28 because the connecting plate 28 is restricted in this direction and will not move. When the second electric push rod 25 drives the selected rack 13 to move along its length direction through the second buckle 26, these racks 13 will drive the sleeve 27 to move synchronously. The sleeve 27 pushes the connecting plate 28 to slide along the through groove 33. The connecting plate 28 transmits power through the connecting rod 29, thereby driving the brush 31 to move synchronously along the guide bar 30, so that the brush 31 can clean the dust attached to the guide plate. At the same time, when the brush passes the bristle 32, the bristle 32 will shake the bristles on the brush 31 to shake off the dust attached to the bristles. An isolation cover 34 is fixedly installed on the outer side of the housing 1, and the switch assembly 6 is located inside the isolation cover 34 to protect the switch assembly 6; The specific application of this embodiment is as follows: when the equipment is working, the temperature and humidity probe 3 collects the temperature and humidity data of the outside of the housing 1 in real time, transmits the data to the main information control module 38 for analysis and processing, and the main information control module 38 outputs the corresponding ventilation control command according to the environmental parameters. When the external environment is hot and dry, the main information control module 38 outputs a full-open command. The first electric push rod 17 pushes the connecting plate 8 to slide along the guide rail 7 to its maximum stroke, causing the Z-shaped guide groove 9 to move synchronously. Each L-shaped rod 10 slides from the second slide groove 19 into the first slide groove 18 and moves laterally outward, pushing the corresponding rack 13 to disengage from the positioning plate 23. Adjacent racks 13 are linked with the slot 21 through the first hook 22. The second electric push rod 25 drives the second buckle 26 to move the linked rack 13 synchronously. The rack 13 drives the spur gear 12 and the rotating shaft 11 to rotate, so that all the guide plates 5 are fully opened. The fan inside the housing 1, together with the double-sided guide plates 5, forms strong convection and quickly dissipates heat and cools down. When the external environment is mild and humid, the main information control module 38 outputs a moderate ventilation command. The first electric push rod 17 pushes the connecting plate 8 to slide with a medium stroke. Only some of the L-shaped rods 10 slide into the first slide groove 18 and move outward, and the corresponding number of racks 13 disengage from the positioning plate. 23. The second electric push rod 25 drives the rack 13 to move slightly, and the guide plate 5 opens at a medium angle to balance heat dissipation and moisture prevention. When the external environment is in a high-humidity and rainy state, the main information control module 38 outputs a full-close command, the first electric push rod 17 drives the connecting plate 8 to reset, all L-shaped rods 10 retract to the second slide groove 19, the rack 13 is locked by the positioning plate 23, and the guide plate 5 is completely closed. The isolation net and the guide plate 5 provide double protection against rain and moisture, protecting the internal circuit. When the external environment is in a low-temperature and dry state, the main information control module 38 outputs a micro-ventilation command, the first electric push rod 17 pushes the connecting plate 8 slightly, only a few L-shaped rods 10 move outward, and the guide plate 5 opens slightly to balance the internal temperature and avoid low-temperature condensation. At the same time, during the ventilation process, when the rack 13 moves along its own length, it also drives the sleeve plate 27, the connecting plate 28, and the connecting rod 29 to move together, thereby driving the brush 31 to slide back and forth along the guide strip 30, automatically cleaning the dust on the surface of the guide plate 5 and maintaining smooth ventilation. Specific Implementation Example 2: like Figure 1 , 2 As shown, this embodiment 2 is based on embodiment 1 and makes the following additions. Specifically, the front of the housing 1 is fixedly installed with a display panel 35, a control room flip cover 36 and a bottom end cover 37 in sequence along the vertical direction. During normal operation, the display panel 35 is used to display the operating status of the terminal in real time. The control room flip cover 36 facilitates the operator to configure and debug parameters. The bottom end cover 37 facilitates wiring and maintenance operations. Inside the housing 1, a main information control module 38, a local communication module 39, a remote communication module 40, a crash detection and restart module 41, and a terminal module 42 are fixedly installed along the vertical direction. The main information control module 38 is responsible for processing multi-source data fusion and logical operations. The local communication module 39 communicates with devices such as meters and sensors in the transformer area. The remote communication module 40 interacts with the main station system via 4G or 5G. The crash detection and restart module 41 monitors the operating status of the main information control module 38 and performs self-recovery when a crash occurs. The terminal module 42 is used to connect external power and signal lines. The crash detection and restart module 41 includes a watchdog unit, a backup power supply unit, a switch execution unit, and a delay control unit. The watchdog unit has a signal input terminal and a status output terminal. The signal input terminal is electrically connected to the signal output terminal of the main information control module 38. The backup power supply unit has a charging terminal and a discharging terminal. The charging terminal is electrically connected to the external main power supply. The discharging terminal is electrically connected to the power supply terminal of the watchdog unit, the control terminal of the switch execution unit, and the power supply terminal of the delay control unit. The switch execution unit has a control signal input terminal, a power input terminal, and a power output terminal. The power input terminal is electrically connected to the main power supply. The power output terminal is electrically connected to the power supply terminal of the main information control module 38. The control signal input terminal is electrically connected to the output terminal of the delay control unit. The delay control unit has a trigger signal input terminal and a command output terminal. The trigger signal input terminal is electrically connected to the status output terminal of the watchdog unit.

[0024] In this specific application, the main information control module 38 periodically sends a working signal to the watchdog unit during normal operation. The signal input terminal of the watchdog unit continuously receives this signal and resets its internal timer. When the main information control module 38 crashes due to high temperature, it stops sending working signals. If the internal timer of the watchdog unit does not receive a working signal after exceeding a preset time threshold, the watchdog unit determines that the main information control module 38 has crashed and sends a trigger signal to the trigger signal input terminal of the delay control unit through its status output terminal. The delay control unit receives the trigger signal. After sending the signal, the switch first sends a power-off command to the control signal input of the switch execution unit through its command output terminal. The switch execution unit then disconnects its power output terminal from the power supply terminal of the main information control module 38, and the main information control module 38 is completely de-energized. At the same time, the delay control unit sends a speed increase command to the fan inside the housing 1 and a drive command to the first electric push rod 17 and the second electric push rod 25. The first electric push rod 17 pushes the connecting plate 8 to slide along the guide rail 7 to its maximum stroke, so that all L-shaped rods 10 slide from the second slide groove 19 into the first slide groove 18 in sequence and move laterally outward, pushing all the teeth. As rack 13 disengages from the positioning plate 23, the second electric push rod 25 drives the second latch 26 to move the linkage rack 13 synchronously. The rack 13 drives the spur gear 12 and the rotating shaft 11 to rotate, causing all guide plates 5 to fully open to their maximum angle. This allows for forced heat dissipation of the interior of the housing 1 with maximum ventilation during the cooling phase, reducing the temperature of the main information control module 38 and its surrounding environment. Simultaneously, the delay control unit starts timing, waiting for the preset cooling time. When the cooling timing ends, the delay control unit sends a power-on command to the control signal input of the switch execution unit through its command output terminal, and the switch execution unit is activated. The unit reconnects its power output terminal to the power supply terminal of the main information control module 38, and the main information control module 38 resumes power supply and restarts. When the main power supply is normal, the backup power unit draws power from the external main power supply and stores energy through its charging terminal. When the main power supply fails or the voltage is abnormal, causing the switch execution unit to malfunction, the backup power unit provides stable operating power to the power supply terminal of the watchdog unit, the control terminal of the switch execution unit, and the power supply terminal of the delay control unit through its discharge terminal, ensuring that the entire crash detection and restart module can still reliably perform power failure and restart operations when the main power supply fails.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
