Description
Technical Field
[0001] This application belongs to the field of computer technology, and in particular relates to a power switching control circuit, system and device. Background Technology
[0002] The power supply for equipment often includes a primary power supply and a backup power supply. In the event of a primary power failure, a backup power supply, such as a generator, can be switched to supply power to the equipment. Existing generators require a starting power supply to power them in order to start generating electricity. However, if the starting power supply is insufficient, the generator will not be able to start normally, resulting in the generator being unable to supply power to the equipment. Therefore, it is necessary to switch to a starting power supply to enable the generator to start normally and ensure uninterrupted power supply to the equipment.
[0003] However, existing technology relies on manual replacement of the generator's starting power supply when it is determined that the generator has not started normally. This results in low switching efficiency of the generator's starting power supply, and manual switching of the power supply also poses certain safety risks. Utility Model Content
[0004] This application provides a power switching control circuit, system, and device that can improve the switching efficiency of a generator's starting power supply.
[0005] In a first aspect, embodiments of this application provide a power switching control circuit, including:
[0006] The voltage detection module is used to detect the input voltage value of the generator when the first power source supplies power to the generator, and to send a control signal to the control module when the input voltage value of the generator is detected to be outside the preset range.
[0007] The control module has a control terminal that is electrically connected to the voltage detection module, a first terminal that is electrically connected to the generator, and a second terminal that is electrically connected to either the first power source or the second power source. The control module is used to respond to a control signal to disconnect the first power source from the generator and to connect the second power source to the generator, so that the second power source supplies power to the generator, thereby causing the generator to rotate and supply power to the equipment.
[0008] Among them, the first power source and the second power source are the starting power sources for the generator.
[0009] Secondly, embodiments of this application provide a power switching control system, including:
[0010] The system includes a first power source, a second power source, a generator, and a power switching control circuit as described in any of the preceding first aspects.

[0012] The detection unit is used to detect the voltage value input to the generator when the first power source supplies power to the generator, and obtain the detection result;
[0013] The switching unit is used to disconnect the first power supply from the generator and connect the second power supply to the generator when the detection result, including the voltage value, is outside a preset range.
[0014] The second power source supplies power to the generator to make the generator rotate and supply power to the equipment. The first and second power sources are the starting power sources for the generator.
[0015] The power switching control circuit, system, and unit provided in this application embodiment detect the input voltage value of the generator when the first power source supplies power to the generator through a voltage detection module. The control module controls the disconnection between the first power source and the generator and controls the connection between the second power source and the generator, so that the second power source supplies power to the generator, thereby causing the generator to rotate and supply power to the equipment. This can realize the automatic switching of the generator's starting power source and improve the power switching efficiency. Attached Figure Description

[0024] The features and exemplary embodiments of various aspects of this application will now be described in detail. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely intended to explain this application and are intended to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples of this application.
[0025] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.
[0026] Before describing the technical solutions provided in the embodiments of this application, in order to facilitate understanding of the embodiments of this application, this application first specifically explains the problems existing in the related technologies:
[0027] In the telecommunications field, high-power generator sets are often installed in the equipment room as backup power to supply power to the operational equipment. However, generator sets often require a starting power supply to start in order to power the operational equipment. But when the starting power supply is insufficient, the generator will not be able to start normally, resulting in the generator being unable to supply power to the equipment. Therefore, it is necessary to switch the starting power supply to enable the generator to start normally and ensure that the equipment is powered without interruption.
[0028] However, the existing battery pack switching circuit has the following drawbacks: 1. It requires manual switching, which results in low switching efficiency and potential safety risks; 2. The battery pack switching circuit has too many intermediate relays, making the logic control complex, debugging complicated, and maintenance inconvenient.
[0029] Based on this, embodiments of this application provide a power switching control circuit, system, and unit that can solve the above problems. The power switching control system provided by embodiments of this application will be described in detail below.
[0030] like Figure 1As shown in the figure, this application provides a power switching control system, which may include a first power supply 101, a second power supply 102, a generator 103, and a power switching control circuit 104.
[0031] Here, as Figure 1 As shown, the power switching control circuit 104 can be disposed between the first power supply 101, the second power supply 102, and the generator 103. The power switching control circuit 104 can be used to disconnect the first power supply 101 from the generator 103 when the first power supply 101 supplies power to the generator 103, and when the voltage value input to the generator 103 is detected to be outside a preset range. Conversely, it controls the second power supply 102 to connect with the generator 103, so that the second power supply 102 supplies power to the generator 103. This allows the generator 103 to use the electrical energy provided by the second power supply 102 to start itself and generate electricity, thereby powering the equipment. Here, the main power supply is used to power the equipment. When the main power supply fails, it cannot provide the required electrical energy to the equipment. Therefore, the generator 103 is needed as a backup power supply to power the equipment. The first power supply 101 and the second power supply 102 are the starting power supplies for the generator 103, and the generator 103 is the backup power supply. By setting up the power switching control system described above, when the first power source 101 is insufficient, the second power source 102 can be switched to supply power to the generator 103 in a timely manner, thereby improving the power switching efficiency and enabling the generator 103 to start normally to supply power to the equipment, so as to ensure that the equipment can still use the backup power to maintain normal operation when the main power source fails.
[0032] In some embodiments, this application provides a power switching control circuit 104, the specific structure of which is as follows: Figure 2 As shown, the circuit described above may include:
[0033] The voltage detection module 201 is used to detect the voltage value input to the generator 103 when the first power supply 101 supplies power to the generator 103, and to send a control signal to the control module when the voltage value input to the generator 103 is detected to be outside the preset range.
[0034] The control module 202 has its control terminal electrically connected to the voltage detection module, its first terminal electrically connected to the generator 103, and its second terminal electrically connected to either the first power supply 101 or the second power supply 102. The control module 202 is used to control the first power supply 101 to disconnect from the generator 103 and control the second power supply 102 to connect with the generator 103 in response to a control signal, so that the second power supply 102 supplies power to the generator 103, thereby starting the generator 103 and supplying power to the equipment. The first power supply 101 and the second power supply 102 are the starting power supplies for the generator 103.
[0035] Here, the generator 103 can be used as a backup power source for the equipment, and the voltage detection module can detect the voltage value input to the generator when the main power supply of the equipment is cut off and the first power supply supplies power to the generator.
[0036] like Figure 2 As shown, the power switching control circuit 104 provided in this embodiment may include the voltage detection module and the control module. The voltage detection module may be a voltage detection relay, and the terminals of the voltage detection relay may be electrically connected to the positive and negative input terminals of the generator 103. The terminals of the voltage detection relay may detect the voltage value input to the positive input terminal and the voltage value input to the negative input terminal of the generator 103. The difference between the voltage value input to the positive input terminal and the voltage value input to the negative input terminal of the generator 103 is used as the voltage value input to the generator 103 for detection. When it is determined that the voltage value is not within the preset range, a control signal may be sent to the control module. For example, taking the generator 103 as a diesel generator 103, the preset range may include [18, 29, 1]. When the voltage detection relay detects that the voltage value is not within the preset range, it will send a control signal to the control module.
[0037] In some examples, the voltage detection module can periodically detect the voltage value input to the generator 103 to achieve real-time monitoring of the voltage value input to the generator 103. This allows for timely switching of the second power supply 102 as the starting power supply for the generator 103 when the first power supply 101 is insufficient. The time delay for the voltage detection module to periodically detect the voltage value input to the generator 103 can be set to 2 seconds. By detecting the voltage value input to the generator 103 once every 2 seconds, the voltage value input to the generator 103 can be detected in a timely manner, allowing for timely replacement of the starting power supply for the generator.
[0038] like Figure 2As shown, when the control terminal of the above control module receives the above control signal, it can control the first power supply 101 to disconnect from the generator 103 and control the second power supply 102 to connect with the generator 103, so that the second power supply 102 supplies power to the generator 103, and the generator 103 can start normally to supply power to the equipment.
[0039] In this embodiment, a voltage detection module detects the voltage value input to the generator 103 when the main power supply is off and the first power supply 101 is supplying power to the generator 103. The control module then controls the first power supply 101 to disconnect from the generator 103 and controls the second power supply 102 to connect to the generator 103, so that the generator 103 starts to supply power to the equipment. This enables automated switching of the generator 103's starting power supply and improves the power switching efficiency.
[0040] In some embodiments, the specific structure of the power switching control circuit 104 is as follows: Figure 3 As shown, the control module may include:
[0041] Control unit 301, the first terminal of control unit 301 is electrically connected to voltage detection module;
[0042] The first switch module 302 has its control terminal electrically connected to the second terminal of the control unit 301, its first terminal electrically connected to the generator 103, its second terminal electrically connected to the first power supply 101, and its third terminal electrically connected to the second power supply 102. When the first terminal and the second terminal of the first switch module 302 are connected, the first power supply 101 supplies power to the generator 103; or, when the first terminal and the third terminal of the first switch module 302 are connected, the second power supply 102 supplies power to the generator 103.
[0043] The control unit 301 is used to control the first terminal of the first switch module 302 to disconnect from the second terminal in response to the control signal, and to control the first terminal of the first switch module 302 to connect to the third terminal, so that the second power supply 102 supplies power to the generator 103.
[0044] In some examples, the first switch module 302 can be a double-throw knife switch. When the first switch module is a double-throw knife switch, the first terminal can include a first sub-terminal and a second sub-terminal. The first sub-terminal can be electrically connected to the generator 103, and the second sub-terminal can be electrically connected to the generator.
[0045] The control unit 301 can control the double-throw switch. The control unit 301 can control the first and second ends of the double-throw switch to be disconnected and the third end to be connected. For example, the control unit 301 controls the double-throw switch to move upward to a preset position so that the first and second ends of the double-throw switch are connected; or the control unit 301 controls the double-throw switch to move downward to a preset position so that the second and third ends of the double-throw switch are connected.
[0046] This application embodiment enables timely and automated switching of the generator 103's starting power supply at low cost by setting up a control module and a first switching unit, thereby improving the power switching efficiency.
[0047] In some embodiments, the specific structure of the power switching control circuit 104 is as follows: Figure 4 As shown, the above control module also includes a stroke motor 401;
[0048] The first end of the stroke motor 401 is electrically connected to the second end of the control unit 301, and the second end of the stroke motor 401 is electrically connected to the control end of the first switch module 302.
[0049] The control unit 301 is used to control the stroke motor 401 to rotate in a first preset direction in response to a control signal so as to disconnect the first end of the first switch module 302 from the second end of the first switch module 302, and to control the stroke motor 401 to run in the first direction to a preset position so as to connect the first end of the first switch module 302 from the third end of the first switch module 302.
[0050] Here, when the first switch module 302 is a double-throw switch, when the first power supply 101 is supplying power, the travel motor 401 rotates along the first direction to the first preset position, and the first end of the double-throw switch can be connected to the third end, so that the second power supply 102 supplies power to the generator 103; when the second power supply 102 supplies power to the generator 103, the travel motor 401 rotates along the second direction to the second preset position, and the first end of the double-throw switch can be connected to the second end, so that the first power supply 101 supplies power to the generator 103.
[0051] This application seems to have the capability to set up a control module including a stroke motor 401, and control the rotation direction of the stroke motor 401 through the control unit 301, so that the first end and the second end of the first switch module 302 are disconnected, and when the stroke motor 401 runs along the first direction to a preset position, the first end and the third end of the first switch module 302 are connected. By driving the different ends of the first switch module 302 to connect or disconnect through the stroke, precise control of the first switch module 302 can be achieved, and the accuracy of power switching can be improved.
[0052] In some embodiments, such as Figure 4 As shown, the voltage detection module includes a first port NO, and the first end of the control unit 301 includes a first control port K. The first port NO of the voltage detection module is electrically connected to the first control port K of the control unit 301.
[0053] The voltage detection module is used to control the normally open first port NO to close when the voltage value of the input generator 103 is detected to be outside the preset range, so that the first port NO can send a control signal to the first control port K; when the first port K receives the control signal, it can generate a first rotation signal, and the control unit 301 can control the stroke motor 401 to rotate in the first preset direction based on the first rotation signal.
[0054] In some examples, a first switch Z1 can be set between NO and K, and a second switch Z2 can be set between C1 and K1. Both switches Z1 and Z2 can remain closed. The first port NO is a normally open port. When the voltage detection module detects that the voltage value of the input generator 103 is outside a preset range, it controls the normally open first port NO to close, allowing the first port NO to send a control signal to the first control terminal. Setting the first switch Z1 and the second switch Z2 facilitates timely disconnection for circuit maintenance. Here, a reversing switch can be used to replace Z1 and Z2.
[0055] Here, as Figure 4 As shown, the voltage detection module may further include a common port C1, and the control unit 301 may further include a common port C2. The common port C1 of the voltage detection module and the common port C2 of the control unit 301 are electrically connected.
[0056] Here, when the first power supply 101 supplies power to the generator 103 and the voltage detection module detects that the voltage value of the input generator 103 is not within a preset range, the voltage detection module can control the conduction between NO and K, so that the first port NO can send a control signal to the first control port K. The control unit 301 can control the stroke motor 401 to rotate in the first preset direction indicated by the first control port K in response to the control signal.
[0057] In some examples, the first end of the control unit 301 includes a control port K1. When the second power supply 102 supplies power to the generator 103 and the voltage detection module detects that the voltage value of the input generator 103 is not within a preset range, the voltage detection module can control C1 to conduct with K1. C1 can send a control signal to K1. The control port K1 can generate a second rotation signal based on the control signal. The control unit 301 can control the stroke motor 401 to rotate in a second preset direction indicated by the second rotation signal in response to the second rotation signal.
[0058] In this embodiment, the voltage detection module is configured to include a first control port K, and the first end of the control unit 301 includes the first control port K. The voltage detection module sends control commands to the control module through the first control port K, so that the control unit 301 can use the first rotation signal generated by the first port K to control the stroke motor 401 to rotate in a first preset direction, thereby achieving precise control of the rotation direction of the stroke motor 401.
[0059] In some embodiments, such as Figure 4 As shown, the control module also includes a stroke detection module 402, and the first end of the control unit 301 also includes a second control port S;
[0060] The first end of the stroke detection module 402 is electrically connected to the voltage detection module 201, and the second end of the stroke detection module 402 is electrically connected to the second control port S of the control unit 301. The stroke detection module 402 is used to control the second control port S to conduct between the voltage detection module 201 and the stroke motor 401 in response to detecting that the stroke motor 401 has moved to a preset position in the first direction.
[0061] It is conceivable that after the second control port S is connected to the voltage detection module 201, the control unit 301 will no longer be able to control the stroke motor 401 to run in the first direction, thus locking the rotation direction of the stroke motor 401 and keeping the connection between the second power supply 102 and the generator 103 stable.
[0062] Here, as Figure 4As shown, the first end of the control unit 301 also includes a third control port S1. The travel detection module 402 may include a travel switch, which includes a first sub-switch Q1 and a second sub-switch Q2. The first end of the first sub-switch Q1 and the first end of the second sub-switch Q2 are both electrically connected to the common port C of the voltage detection module 201. The second end of the first sub-switch Q1 is electrically connected to the second control port S, and the second end of the second sub-switch Q2 is electrically connected to the third control port S1.
[0063] When the first power supply 101 supplies power to the generator 103 and the control unit 301 controls the stroke motor 401 to rotate along the first preset direction, the stroke detection module 402 can control the first sub-switch Q1 to close in response to detecting that the stroke motor 401 has moved to the first preset position along the first direction, so that the second control port S is connected to the voltage detection module 201, and the stroke motor 401 stops rotating.
[0064] When the second power supply 102 supplies power to the generator 103 and the control unit 301 controls the stroke motor 401 to rotate along the second preset direction, the stroke detection module 402 can control the second sub-switch Q2 to close when it detects that the stroke motor 401 has moved to the second preset position along the second direction, so that the third control port S1 is connected to the voltage detection module 201 and the stroke motor 401 stops rotating.
[0065] It is conceivable that when the third control port S1 is connected to the voltage detection module 201, the control unit 301 cannot control the stroke motor 401 to run in the second direction again, so that the stroke motor cannot continue to rotate in the second direction.
[0066] In this embodiment, by setting up a stroke detection module 402, when the stroke motor 401 is detected to have moved to a preset position along the first preset direction, the second control port S is promptly connected to the voltage detection module, and the stroke motor stops rotating. This enables timely control of stopping the stroke motor 401, ensuring a stable connection between the second power supply 102 and the generator 103.
[0067] In some embodiments, such as Figure 4 As shown, the power switching control circuit 104 also includes an uninterruptible power supply 403, which is electrically connected to both the control module 202 and the voltage detection module 201. The uninterruptible power supply is used to supply power to the control module 202 and the voltage detection module 201.
[0068] Here, the uninterruptible power supply mentioned above can be the uninterruptible power supply (UPS) of the output row cabinet. By using the uninterruptible power supply as the power supply for the control module 202 and voltage detection module 201 of the power switching control circuit 104, the power switching control circuit 104 can be unaffected by the power failure of the main power supply and the change in the power of the engine starting power supply. It can still maintain normal operation in the event of power failure of the main power supply and the change in the power of the generator 103 starting power supply, which is conducive to timely switching of the generator 103 starting power supply.
[0069] In some embodiments, such as Figure 4 As shown, the power switching control circuit 104 also includes a rectifier 404. The first end of the rectifier is electrically connected to the uninterruptible power supply 403, and the second end of the rectifier 404 is electrically connected to both the control module 202 and the voltage detection module 201. The rectifier is used to convert the AC power output by the uninterruptible power supply into DC power within the preset voltage range required by the voltage detection module 201 and the control module 202.
[0070] like Figure 4 The aforementioned rectifier can be electrically connected to the control unit 301.
[0071] The aforementioned rectifier can convert the AC power output from the uninterruptible power supply into DC power within a preset voltage range required by the voltage detection module 201, and into DC power with a preset voltage value required by the control module 202. For example, the aforementioned rectifier can convert the 185-242V AC power output from the uninterruptible power supply into 3-24V DC power.
[0072] This embodiment of the application sets up a rectifier, and the rectifier 404 converts the AC power output of the uninterruptible power supply into DC power within a preset voltage range, which can realize the normal use of the voltage detection module 201 and the control module 202, and facilitate the timely switching of the generator's starting power supply.
[0073] In some embodiments, such as Figure 5 As shown, this application embodiment provides a power switching control method, which may include the following steps S510-S520:
[0074] S510: When the first power source supplies power to the generator, detect the voltage value input to the generator and obtain the detection result;
[0075] S520: If the detection result, including the voltage value, is outside the preset range, the control disconnects the first power supply from the generator and connects the second power supply to the generator. The second power supply supplies power to the generator to start the generator and supply power to the equipment. The first power supply and the second power supply are the generator's starting power supplies.
[0076] This embodiment of the application detects the voltage value input to the generator when the first power source supplies power to the generator, obtains the detection result, and determines that the voltage value of the detection structure is within a non-preset range. By controlling the disconnection between the first power source and the generator and controlling the connection between the second power source and the generator, the starting power source of the generator can be automatically switched, thereby improving the switching efficiency of the generator's starting power source.
[0077] In some embodiments, the above-mentioned control of disconnecting the first power source from the generator and controlling the second power source to connect the generator when the detection result, including the voltage value, is outside a preset range may include:
[0078] The control unit responds to the control signal to disconnect the first terminal of the first switch module from the second terminal of the first switch module, and controls the first terminal of the first switch module to connect with the third terminal of the first switch module, so that the second power source supplies power to the generator.
[0079] In some embodiments, controlling the first terminal of the first switch module to disconnect from the second terminal of the first switch module and controlling the first terminal of the first switch module to connect with the third terminal of the first switch module in response to a control signal may include:
[0080] The control unit responds to the control signal to control the stroke motor to rotate in a first preset direction so as to disconnect the first end of the first switch module from the second end of the first switch module, and controls the stroke motor to run in the first direction to a preset position so as to connect the first end of the first switch module from the third end of the first switch module.
[0081] In some embodiments, controlling the stroke motor to rotate along a first preset direction in response to a control signal by a control unit may include:
[0082] Upon receiving a control command, the first control port in the control unit controls the stroke motor to rotate in a first preset direction indicated by the first rotation signal generated by the first rotation signal.
[0083] In some embodiments, after controlling the stroke motor to run along the first direction to a preset position, the method further includes:
[0084] When the travel motor is detected to have moved to a preset position in the first direction, the travel motor is controlled to stop rotating.
[0085] The power switching control method described above is applied to the corresponding power switching control circuit in any of the foregoing embodiments and has the beneficial effects of the corresponding circuit embodiments, which will not be repeated here.
[0086] In some embodiments, such as Figure 6 As shown, this application embodiment provides a power switching control unit, including:
[0087] The detection unit 601 is used to detect the voltage value input to the generator when the first power source supplies power to the generator, and obtain the detection result;
[0088] The switching unit 602 is used to control the first power supply to disconnect from the generator and control the second power supply to connect to the generator when the detection result, including the voltage value, is outside the preset range. The second power supply supplies power to the generator so that the generator starts and supplies power to the equipment. The first power supply and the second power supply are the starting power supplies for the generator.
[0089] In some embodiments, the switching unit may specifically be used for:
[0090] The control unit responds to the control signal to disconnect the first terminal of the first switch module from the second terminal of the first switch module, and controls the first terminal of the first switch module to connect with the third terminal of the first switch module, so that the second power source supplies power to the generator.
[0091] In some embodiments, the switching unit may specifically be used for:
