Description

Technical Field

[0001] The present invention relates to the technical field of circuit control, and in particular to a dual-power supply fast switching device based on a wavelet algorithm. Background Art

[0002] Continuous production enterprises, such as those in the petrochemical and chemical industries, place extremely high demands on power continuity. Power system failures, such as power outages and power outages, can cause significant economic losses or safety impacts to the enterprise, leading to shutdowns and restarts of control systems and motor loads. Therefore, ensuring the continuous and safe operation of loads in the event of a power failure is essential and highly valuable.

[0003] Conventional solutions for power continuity currently include power switching and automatic equipment switching. While these solutions can address discontinuous production processes, they are inadequate for continuous production processes, such as those in the petrochemical and chemical industries. This is primarily due to the lengthy switching times associated with these solutions, which in turn result in prolonged power outages and are therefore unable to meet the process requirements of continuous production.

[0004] The task of quick switching is to switch the load to the backup line as quickly as possible according to the system status when the power supply line is cut off, so as to avoid operation interruption or equipment impact damage during power switching, so as to ensure uninterrupted and continuous operation of electrical equipment.

[0005] Announcement No. CN111354585A discloses a dual power switching device, including a driving turntable, side wing support bodies installed on both sides of the driving turntable, and terminal blocks located between the side wing support bodies on both sides. Moving contacts are installed on opposite surfaces of the side wing support bodies on both sides, and static contacts are installed on both sides of the terminal blocks. Moving conductors connecting a common terminal and a moving contact are installed in the driving turntable and the side wing support bodies. A U-shaped conductor is installed in the driving turntable. A separation auxiliary mechanism is installed on the driving turntable. On the side where the electromagnetic shielding component is not installed, the moving conductor and the U-shaped conductor generate an attractive electric force on each other due to the same current direction, which prevents the moving contact from being bounced off when it contacts the static contact. When switching the power, the common terminal is disconnected from the connected side of the circuit through the separation auxiliary mechanism, so that the corresponding moving conductor and the U-shaped conductor lose the attractive electric force, thereby avoiding the disadvantage of slow switching of the two power supplies.

[0006] When the dual power supply fast switching device switches the power supply, the separation mechanism is used to control the terminal to separate from one of the power supplies, and then the terminal is controlled to connect to the other power supply to achieve switching between the dual power supplies. However, since the movement path of the separation mechanism is fixed, the time for separating and then connecting the terminal is limited, resulting in slow switching of the dual power supplies and inability to achieve fast switching. Summary of the Invention

Unless otherwise explicitly defined, these words should not be interpreted as having idealized or overly formal meanings.

[0063] See also Figures 1-12 The present invention provides a dual power supply fast switching device based on wavelet algorithm to switch the power supply of the power supply line to ensure the power stability of the equipment and loads in the power supply line.

[0064] In one embodiment, the switching device comprises:

[0065] The housing 1 has a plurality of mounting holes 2 on its back for fixed installation. The top of the housing 1 is provided with a plurality of mounting heads 3 for fixing the power supply end. Screws are provided inside the mounting heads 3 for fixing the power supply end. A conductive head 4 is provided on one side of the mounting head 3. The power supply end is installed inside the mounting head 3 to make the conductive head 4 conductive.

[0066] A terminal 6 is movably disposed inside the housing 1. A fixing head 5 is provided on one side of the terminal 6 for fixing one end of the power supply line extending into the interior of the terminal 6, thereby limiting the position of the terminal 6 and the power supply line. When the terminal 6 contacts the conductive head 4, the power supply line is connected to the power supply for electrical conduction.

[0067] Wavelet analysis system 7, which gradually refines the signal at multiple scales through sampling, wavelet basis construction, wavelet transform scaling and translation operations, extracts power outage features, and determines the power status based on the power outage features;

[0068] A motion mechanism 8 is disposed within the housing 1 and controls the contact and separation between the terminal 6 and the conductive head 4. The motion mechanism 8 changes the position of the terminal 6 based on the analysis of the power supply status by the wavelet analysis system 7. The spacing between the terminal 6 and the backup power conductive head 4 is determined by the power supply status.

[0069] The posture adjustment component 9 is arranged inside the shell 1 and is used to adjust the posture of the terminal 6, change the contact area and angle between the terminal 6 and the conductive head 4, and the posture adjustment component 9 includes a blocking plate 91 for blocking the power supply between the terminal 6 and the conductive head 4 and controlling the position of the blocking plate 91.

[0070] In this embodiment, the position of the terminal 6 is changed by setting a motion mechanism 8, and the gap between the terminal 6 and the conductive head 4 is adjusted, thereby changing the initial distance between the terminal 6 and the conductive head 4 before contact. By adjusting the posture of the terminal 6, the axis of the terminal 6 and the conductive head 4 can be made to be inclined at an angle, thereby changing the contact area between the terminal 6 and the conductive head 4.

[0071] One end of the terminal 6 is set to a polygon. During use, the angle of the terminal 6 is changed according to the posture adjustment component 9, and the contact area between the terminal 6 and one end face of the conductive head 4 can be adjusted. According to the change in the angle of the terminal 6, the contact force between the terminal 6 and the conductive head 4 changes, so that the blocking plate 91 can be inserted between the terminal 6 and the conductive head 4 more quickly.

[0072] In one embodiment, the side of one end of the terminal 6 that contacts the conductive head 4 is set as a polygonal structure, and the polygonal structures correspond to different angle adjustment components 9 respectively. An elastic member 10 is set between the terminal 6 and the fixed head 5 to form a support for the terminal 6. When the posture adjustment component 9 changes the angle of the terminal 6, the elastic member 10 supports the change in the contact force between the terminal 6 and the conductive head 4. The terminal 6 is a combined structure. The terminal 6 installed at one end of the fixed head 5 can swing, and the other end can be retracted.

[0073] In this embodiment, the terminal 6 is a double-ended retractable device. When in use, one end of the terminal 6 moves outward under the support of the elastic member 10. When it is close to the conductive head 4, the elastic member 10 can be used to support the terminal 6, so that the terminal 6 is in contact with the conductive head 4, and the power supply and power supply circuit are energized.

[0074] Optionally, the elastic member 10 is a compression spring, which is located between the fixed head 5 and the terminal 6 to support the retractable end of the terminal 6.

[0075] Among them, the posture adjustment component 9 is located inside the shell 1 and moves with the terminal 6. The cross-section of the terminal 6 is cylindrical. After changing the angle of the terminal 6, the contact area between the polygonal structure and the conductive head 4 changes.

[0076] In one embodiment, the posture adjustment component 9 includes:

[0077] The electromagnetic frame is composed of an electromagnet 93 and a mounting frame 92 for mounting a blocking plate 91. A magnetic plate 94 is provided on one side of the electromagnetic frame. The magnetic plate 94 is fixed inside the housing 1. The electromagnet 93 and the magnetic plate 94 interact to control the mounting frame 92 to slide inside the housing 1. The movement path of the blocking plate 91 is located between the terminal 6 and the conductive head 4.

[0078] The conductive region 95 is located in the blocking plate 91 and is composed of a plurality of conductive plates with different conductivity coefficients.

[0079] In this embodiment, the blocking plate 91 serves to block the terminal 6 and the conductive head 4, so that the blocking plate 91 can quickly realize the connection and separation between the terminal 6 and the conductive head 4 during use, and the position of the blocking plate 91 is controlled through the magnetic interaction between the electromagnetic frame and the magnetic plate 94. When the blocking plate 91 is retracted, the terminal 6 and the conductive head 4 are in stable contact.

[0080] Conductive plates with different conductivity coefficients are set. Due to the different conductivity coefficients, when the current is the same, there will be a larger voltage drop on the conductive plate with a lower conductivity coefficient, while the voltage drop on the conductive plate with a higher conductivity coefficient is smaller.

[0081] In one embodiment, the posture adjustment component 9 further includes:

[0082] A slideway 96 is provided inside the housing 1 . The extension direction of the slideway 96 is consistent with the movement direction of the terminal 6 . A slide 97 is provided inside the slideway 96 . The slide 97 is slidably provided inside the slideway 96 and cannot be separated from the slideway 96 .

[0083] A chuck 98 is swingably disposed on one end of the carriage 97 facing the terminal 6. One end of the chuck 98 clamps the connecting post and moves with the terminal 6. The other end of the chuck 98 extends into the interior of the carriage 97 and is capable of swinging relative to the carriage 97.

[0084] The driving rod 99 is arranged inside the slide 97. Driving parts 910 are set at both ends of the driving rod 99 to change the position of the driving rod 99. The driving rod 99 is engaged with one end of the clamp 98 extending to the inside of the slide 97 for transmission.

[0085] Optionally, the driving member 910 is an electromagnetic block, and the driving rod 99 is pulled by the electromagnetic blocks located at both ends of the driving rod 99;

[0086] In another optional embodiment, the driving member 910 is a miniature telescopic rod, and the miniature telescopic rod is extended and retracted to change the position of the driving member 910 .

[0087] In this embodiment, since the driving rod 99 is engaged with the chuck 98 , when the driving rod 99 moves, the swing angle of the chuck 98 can be changed, and the position of the connecting column can be adjusted according to the swing angle of the chuck 98 .

[0088] The axis of one end of the chuck 98 extending to the inside of the slide 97 coincides with the axis of the connection position between the connecting column and the fixed head 5. The swing of the driving rod 99 can correspondingly change the swing angle of the connecting column, thereby accurately controlling the position of the connecting column.

[0089] In one embodiment, the motion mechanism 8 includes:

[0090] The slide plate 81 is slidably disposed inside the housing 1 , and the fixed head 5 is mounted on the inner side of the slide plate 81 , and the sliding movement drives the fixed head 5 to move;

[0091] A pressure chamber 82 is provided at one end of the slide 81 away from the fixed head 5 . The pressure chamber 82 is elastically provided and filled with a medium. The slide 81 is driven to move by changes in the medium pressure in the pressure chamber 82 .

[0092] In this embodiment, the pressure change of the medium is used to drive the slide 81 to move. The greater the medium pressure inside the pressure chamber 82, the faster the slide 81 is pushed, resulting in a shorter contact time between the connecting column and the conductive head 4.

[0093] Among them, one end of the pressure chamber 82 extends to the pushing position of the slide 81. The change in the medium pressure inside the pressure chamber 82 causes the slide 81 to slide inside the shell 1. In order to facilitate the control of the pressure chamber 82, an electric control valve is provided between the pressure chamber 82 and the slide 81 to control the communication state between the pressure chamber 82 and the slide 81. The electric control valve controls the opening and closing of the pressure chamber 82.

[0094] In one embodiment, a pulling rod 83 is provided on one side of the pressure chamber 82, and a pressure plate 84 is provided on one end of the pulling rod 83 close to the pressure chamber 82. The pulling rod 83 changes the position of the pressure plate 84 to control the pressure change inside the pressure chamber 82.

[0095] The slide plate 81 is split and the three sections of the slide plate 81 can slide independently. The pulling rod 83 and the pressure chamber 82 are respectively installed on the outside of two sections of the slide plate 81 and push the other section of the slide plate 81 to slide through the pressure chamber 82.

[0096] In this embodiment, the slide 81 is set to a three-section type, which can facilitate the change of the position of the pressure chamber 82 by the pulling rod 83, and each section of the three-section slide 81 is restricted in sliding position, so that the slide 81 can be controlled to drive the fixed head 5 to change position.

[0097] In one embodiment, the motion mechanism 8 further comprises:

[0098] The electromagnetic strips 85 are installed between the slide 81 and the housing 1, and the electromagnetic strips 85 are installed on the slide 81 and the surface of the housing 1. When the electromagnetic strips 85 are energized, the sliding position of the slide 81 is determined by the change in the magnetic force of the electromagnetic strips 85.

[0099] The electromagnetic strips 85 are arranged tilted, and the tilt angles of the electromagnetic strips 85 are consistent.

[0100] In this embodiment, by changing the state of the electromagnetic strips 85, the slide plate 81 can slide inside the shell 1. When the magnetic forces of the two electromagnetic strips 85 repel each other, the electromagnet 93 is tilted, which pushes the slide plate 81 to move outward and slide to different positions.

[0101] When the magnetic forces of the two electromagnetic strips 85 attract each other, the position of the slide plate 81 is fixed and the slide plate 81 does not change position.

[0102] The three-stage slide 81 is equipped with electromagnetic bars 85 to control the positions of the slides 81 respectively, thereby limiting the slides 81 to different positions.

[0103] In one embodiment, a swingable positioning bar 86 is provided between the electromagnetic bar 85 installed on the inner side of the slide 81 and the slide 81 . The positioning bar 86 is swingably provided on the inner side of the slide 81 , and the magnetic force change of the electromagnetic bar 85 changes the swing angle of the positioning bar 86 .

[0104] In this embodiment, through the swingable positioning bar 86, when the electromagnetic bar 85 located inside the shell 1 presents different magnetic force changes, the swing angle of the positioning bar 86 can be changed, so that the positioning bar 86 can stably drive the electromagnetic bar 85 to move and control the position of the electromagnetic bar 85.

[0105] In one embodiment, the wavelet analysis system 7 performs analysis as follows:

[0106] Signal acquisition: Real-time acquisition of voltage signals of the main power supply and backup power supply as input data for wavelet transform;

[0107] Wavelet transform: Perform wavelet transform on the collected voltage signal to decompose the signal into different frequency components and analyze the time characteristics of each component;

[0108] Feature extraction: Through wavelet transform, the features of the voltage signal are extracted, such as the modulus maximum point. The feature point corresponds to the mutation point of the signal and is used to detect voltage drops or anomalies.

[0109] Status judgment: Based on the extracted feature points, determine whether the power supply voltage is abnormal. If the main power supply voltage is abnormal, a switching instruction is issued to switch the power supply line to the backup power supply;

[0110] Switching execution: After receiving the switching instruction, the switching device controls the terminal 6 through the motion mechanism 8 to disconnect the main power supply and connect the backup power supply to complete the power switching process.

[0111] In this embodiment, the voltage signal is analyzed by wavelet to obtain the power supply status of the main power supply, and the distance between the terminal 6 and the backup power supply conductive head 4 is adjusted according to the power supply status of the main power supply.

[0112] In one embodiment, based on the extracted feature points, it is determined whether the power supply voltage is abnormal. The specific method includes:

[0113] Threshold judgment: Set a voltage change threshold. When the voltage change exceeds the threshold, it is considered abnormal and the power supply needs to be switched.

[0114] Pattern recognition: Use machine learning algorithms such as support vector machines and neural networks to classify the extracted features and determine whether the voltage status is abnormal;

[0115] According to the voltage change state, the distance between the terminal 6 and the conductive head 4 is adjusted by the motion mechanism 8.

[0116] For example, the voltage signals of the main power supply and the backup power supply are collected in real time. Through wavelet transformation, it is found that the voltage of the main power supply has a significant drop at a certain moment.

[0117] By extracting the modulus maximum point, it is determined that the voltage drop exceeds the set threshold, so a switching instruction is issued to switch the load to the backup power supply.

[0118] This method uses the time-frequency analysis capability of wavelet transform to effectively detect changes in power supply voltage and ensure that the dual power supply switching device can switch quickly and accurately in the event of a power failure.

[0119] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0120] 1. The present application adjusts the distance and connection status between the terminal 6 and the dual power supply through the voltage change state, dynamically changes the position of the terminal 6, and optimizes the on-off path of the terminal 6 and the dual power supply, so as to reduce the time consumed in the dual power supply switching process, ensure the stability of the dual power supply switching process, avoid operation interruption or equipment impact damage during power switching, and ensure uninterrupted and continuous operation of electrical equipment.

[0121] 2. The signal is gradually refined at multiple scales through sampling, wavelet basis construction, and wavelet transform scaling and translation operations. This can fully highlight the mutation characteristics, extract the power-off characteristics, and quickly identify the status of the power supply line. According to the status of the power supply line, the position of the terminal 6 is controlled to change, thereby realizing rapid switching of dual power supplies and changing the movement path of the terminal 6 based on the status of the power supply line.

[0122] 3. The position of the terminal 6 is controlled by the motion mechanism 8 to realize the on-off connection between the terminal 6 and the dual power supply. The terminal 6 matches the number of power supplies. When in use, the two terminal 6 correspond to two power supplies respectively, and the two terminal 6 are connected to the power supply line. When one of the terminal 6 is connected to the corresponding power supply, the power supply line can be powered.

[0123] 4. In the process of using the motion mechanism 8 to move the terminal 6, the state of the terminal 6 is adjusted through the posture adjustment component 9. During the separation adjustment process, the connection between the terminal 6 and the power supply can be quickly achieved, and the isolation plate is used to disconnect the terminal 6 from the power supply to avoid involvement between the terminal 6 and the power supply during the separation process.

[0124] Although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the attached claims.
