Description

Technical Field

[0001] The present application relates to the field of network communication technology, and in particular to a device supporting hot plugging and a hot plugging implementation method. Background Art

[0002] In the modular design of communication equipment, a modular structure that supports hot-swap functions is usually adopted, and each module is designed with a dedicated hot-swap circuit. When the module is inserted into the communication equipment, it will go through a transition process from a power-off state to a power-on state, and the hot-swap circuit can play a buffering role, which can not only prevent the module from being damaged by instantaneous impact current, but also avoid the system voltage drop caused by the current impact, which may cause abnormal operation of the entire system.

[0003] Figure 1 A schematic diagram of an existing hot-swap system is shown. In this system, multiple pluggable modules can be inserted into a chassis at the same time. Each pluggable module is equipped with a hot-swap circuit. However, this design has some defects: each pluggable module needs to be equipped with a hot-swap circuit. However, this circuit only works during the module insertion process. Once the module is fully inserted and locked, the circuit loses its value. This not only leads to low circuit utilization, but also increases certain material costs. When the module is inserted and starts working, the module's operating current needs to flow through the hot-swap circuit. In this process, the hot-swap circuit will generate a certain amount of power loss. This means that for each module, the hot-swap circuit will cause continuous power loss. Under the same conditions, the greater the power of the module, the greater the loss it generates in the hot-swap circuit. This not only affects the energy efficiency of the module, but also may limit the overall performance of the system.

[0004] Therefore, how to implement a hot-swap solution that saves costs and reduces circuit power consumption is a technical problem that needs to be solved. Summary of the invention

[0005] In view of this, one of the purposes of the present invention is to provide a device supporting hot plugging and a hot plugging implementation method, so as to realize a hot plugging solution that saves costs and reduces circuit power consumption. The present invention can be implemented as follows:

[0010] In an optional embodiment, a rectangular notch is provided on one side of the structural support member of the pluggable module; the rectangular notch is used to prevent the pluggable module from entering a locked state during the insertion or removal process.

[0011] In an optional implementation, during the process of inserting or removing any of the pluggable modules from a certain slot, the power receiving contact on any of the pluggable modules contacts the power supply output end to supply power to the pluggable module.

[0014] In an optional implementation, a power supply connector is further installed on the frame; the power supply connector is used to supply power to the pluggable module when any of the pluggable modules is fully inserted into a slot.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0039] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0041] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0042] Considering that the cost of existing hot-plug solutions and the power consumption of pluggable modules are both high, based on this, an embodiment of the present invention provides a device supporting hot-plugging and a hot-plugging implementation method, which are described below through embodiments.

[0043] See 2, Figure 2 1 is an architecture diagram of a hot-swappable device 00 provided in an embodiment of the present invention, including a frame 10 and a plurality of pluggable modules 20; a hot-swappable circuit 101 and a plurality of slots 102 are provided on the frame 10, that is, Figure 2 Slot 1 to slot N in the slot 102; a power switch 1021 is installed on one side of each slot 102, that is, Figure 2 The power switches 1 to N in the hot-swap circuit 101 are connected in parallel to the hot-swap circuit 101; the power output terminals 1011 of the hot-swap circuit 101, i.e., the power output terminals 1 to N are installed in parallel on the side where the power switch 1021 is located. It should be understood that Figure 1 The relative positions of the power supply output terminal 1011 and the power supply switch 1021 shown in FIG. 1 are merely examples and are not intended to limit their relative positions.

[0044] On any slot 102, when the pluggable module 20 is inserted or removed, the power switch 1021 is triggered to close, and the power output end 1011 supplies power to the pluggable module 20; when the pluggable module 20 is fully inserted or fully removed, the power switch 1021 is triggered to open, and the power output end 1011 stops supplying power to the pluggable module.

[0045] The hot-swap-supporting device 00 provided in the embodiment of the present invention is Figure 1The traditional hot-swap system shown has significant advantages. First, the embodiment of the present invention removes the hot-swap circuit on each pluggable module 20, and instead designs a set of common hot-swap circuits on the frame 10. In this way, multiple pluggable modules 20 can share the same hot-swap circuit 101, thereby significantly reducing the cost of the overall device. Secondly, the hot-swap circuit 101 includes a power supply output terminal 1011 that is the same as the number of slots, and each slot 102 is installed with a power supply output terminal 1011. The hot-swap circuit 101 in the embodiment of the present invention only supplies power during the insertion or removal of the pluggable module 20. Once the pluggable module 20 is fully inserted or fully removed, the circuit stops working. The embodiment of the present invention not only optimizes the cost-effectiveness of the hot-swap system, but also significantly improves the utilization rate of the circuit, while also reducing circuit losses.

[0046] In one embodiment of the present invention, Figure 3 As shown, Figure 3 1 shows a possible appearance of a host 101 in an embodiment of the present invention. The frame 10 is equipped with a plurality of slots 102, which are designed to accommodate a plurality of pluggable modules 20. For further information, see Figure 4 , Figure 4 A pluggable schematic diagram provided for an embodiment of the present invention clearly shows the insertion and removal process of the pluggable module.

[0047] In one embodiment of the present invention, since the entire device is equipped with only one set of hot-swap circuits, this means that only one pluggable module can be inserted or unplugged at the same time. In order to ensure that more than one module will not attempt to be inserted at the same time, the embodiment of the present invention also adds a locking device to the frame 10 to prevent such potential conflicts. For ease of understanding, please refer to Figure 5 , Figure 5 One of another architecture diagrams of a device supporting hot plugging provided in an embodiment of the present invention.

[0048] It should be pointed out that although Figure 5 Multiple locking devices 1022 are depicted, but they are actually the same locking device. That is, the power switches 1 to N are all connected to the same locking device 1022. The advantages of this design will be more clearly explained in the detailed description of the structure of the locking device 1022 later.

[0049] exist Figure 5In the embodiment, a locking device 1022 is installed on the frame 10, and the locking device 1022 runs through the other side of all slots 102. The other side of the slot 102 refers to the side where the power switch is not installed. When any pluggable module 20 is inserted into or removed from a slot 102, the locking device 1022 is linked with the power switch 1021 to make the pluggable modules 20 on other slots 102 in a locked state; when any pluggable module 20 is fully inserted into or fully removed from the slot 102, the locking device 1022 is linked with the power switch 1021 to make the pluggable modules 20 on all slots 102 in a movable state.

[0050] In the embodiment of the present invention, linkage control is implemented between the locking device 1022 and the power switch 1021. Specifically, when the power switch 1021 is in the off state, the locking device 1022 will also be off; and when the power switch 1021 is closed, the locking device 1022 will also be closed accordingly. This collaborative working mechanism enables the locking device 1022 and the power switch 1021 to jointly complete the locking or unlocking operation of the pluggable module 20 on other slots.

[0051] Furthermore, the "locked state" referred to in the embodiments of the present invention means that when a certain slot is being inserted or removed, the pluggable modules in other slots cannot be inserted or removed and are in a fixed position. On the contrary, the "movable state" means that the pluggable module can be inserted or removed and the module is in a state where movement is allowed.

[0052] That is to say, when the hot-swap circuit 101 is in working state, if there are pluggable modules 20 in other slots 102, the locking device 1022 and the power switch 1021 will work together to physically lock these modules, thereby ensuring that only one pluggable module is inserted or removed at the same time. Correspondingly, when the hot-swap circuit 101 is not in working state, the locking device 1022 can unlock the pluggable modules 20 in other slots, so that these modules can continue to use the hot-swap circuit 101. Such a design can prevent potential operation conflicts and enhance the protection of the pluggable modules 20, and also provide the flexibility of hot-swapping the modules in the non-working state.

[0053] Further, in one embodiment of the present invention, Figure 5 The design scheme of the locking device 1022 is as follows Figure 6 As shown, Figure 6The structural block diagram of the locking device provided by the embodiment of the present invention is shown. The locking device 1022 includes a solenoid valve 1022-1, a locking latch 1022-2 and a locking switch 1022-3; when the locking switch 1022-3 is closed, the solenoid valve 1022-1 is triggered to drag the locking latch 1022-2 to lock the pluggable modules on other slots, and when the locking switch is disconnected, the solenoid valve is triggered to drag the locking latch to unlock the pluggable modules on other slots.

[0054] In the embodiment of the present invention, the locking pin 1022-2 may be composed of a main rod and a plurality of cross rods, and the cross rods extend horizontally from one side of the main rod, so that the locking pin 1022-2 presents an "F" shape as a whole. For an intuitive understanding of this design, please refer to Figure 7 , Figure 7 A possible physical diagram of the locking device provided by an embodiment of the present invention is shown. The locking switch 1022-3 is omitted in the figure. It can be seen that the locking latch 1022-2 is in an inverted "F" shape and is installed in the machine frame 10. The solenoid valve 1022-1 is connected to the end of the main rod of the locking latch 1022-2, and one end of each cross bar is inserted into the slot 102 to achieve a precise locking function.

[0055] During the process of inserting any pluggable module 20 into a certain slot 102, the solenoid valve 1022-1 drags the main rod in a direction vertically approaching the pluggable module 20 so that one end of each cross bar clamps the pluggable module 20 on other slots 102; during the process of pulling any pluggable module 20 out of a certain slot 102, the solenoid valve 1022-1 drags the main rod in a direction vertically away from the pluggable module 20 so that one end of each cross bar releases the pluggable module 20 on other slots.

[0056] For easier understanding, please refer to Figure 7 ,exist Figure 7 In the embodiment, when the solenoid valve 1022-1 drags the solenoid valve 1022-1 in the downward direction, one end of the crossbar extending into each slot 102 can clamp the pluggable module 20, and the pluggable module 20 is in a locked state, and insertion or removal operations are prohibited. Correspondingly, when the solenoid valve 1022-1 drags the solenoid valve 1022-1 in the upward direction, one end of the crossbar in each slot 102 releases the clamped pluggable module 20, and the pluggable module 20 is in a movable state, and insertion or removal operations can be performed.

[0057] based on Figures 5 to 7In order to prevent the pluggable module being inserted or removed from being locked, the embodiment of the present invention has also made corresponding improvements to the pluggable module 20, that is, a rectangular notch 201 is provided on one side of the structural support member of the pluggable module 20; the rectangular notch 201 is used to prevent the pluggable module 20 from entering a locked state during the insertion or removal process.

[0058] To understand this design, see Figure 8 , Figure 8 One of the partial architecture diagrams of a device supporting hot plugging provided by an embodiment of the present invention, Fig. 9 A possible physical display diagram of the pluggable module provided by an embodiment of the present invention is shown, wherein the rectangular notch 201 design of the pluggable module 20 is shown.

[0059] from Figure 8 It can be seen that the position of the rectangular notch 201 corresponds to the position of the locking device 1022 in the slot 102. This means that when inserting the pluggable module 20, the side with the rectangular notch 201 should be aligned with the side with the locking device 1022 in the slot 102, and then the insertion operation is performed. This design ensures that the pluggable module 20 being plugged in will not be locked by the locking device 1022 due to the presence of the rectangular notch 201.

[0060] Through the above embodiments, the embodiment of the present invention can ensure that only one pluggable module 20 is allowed to perform plugging and unplugging operations at the same time by adding a locking device 1022 in the frame 10, thereby preventing operation conflicts. Next, the embodiment of the present invention will introduce the specific implementation process of realizing the hot-swap circuit 101 to power the pluggable module 20 in conjunction with the relevant drawings.

[0061] See also Fig.10 , Fig.10 The second partial structural diagram of the hot-swap supporting device provided in the embodiment of the present invention, in the slot 102, the power output terminal 1011 of the hot-swap circuit 101 is installed on the side where the power switch 1021 is located; the pluggable module 20 is also provided with a power receiving contact 202 accordingly.

[0062] The position of the power receiving contact 202 corresponds to the position of the power output terminal 1011. This means that during the process of inserting the pluggable module 20, the side of the slot 102 where the power receiving contact 202 is designed is aligned with the side where the power output terminal 1011 is located, and then the insertion operation is performed. During the process of inserting or removing the pluggable module 20, the power receiving contact 202 on the pluggable module 20 contacts the power output terminal 1011 to realize power supply to the pluggable module 20.

[0063] In order to understand the above design more intuitively, Fig.11The schematic diagram of the insertion process of the pluggable module 20 provided by the embodiment of the present invention is shown. It can be clearly seen from the figure that when the pluggable module 20 is inserted into the slot 102, its power receiving contact 202 immediately contacts the power supply output terminal 1011 on the side of the slot 102. At this time, if the hot plug circuit 101 is turned on, the power receiving contact 202 of the pluggable module 20 contacts the power supply output terminal 1011, and the power supply output terminal 1011 of the hot plug circuit 101 will supply power to the pluggable module 20.

[0064] It can also be seen that after the pluggable module 20 is inserted into the slot 102 , the locking device 1022 cannot physically lock the pluggable module 20 due to the presence of the rectangular notch 201 . The introduction of the rectangular notch 201 can ensure the smooth execution of the insertion process.

[0065] In order to precisely control the on / off state of the power switch 1021 to start or shut down the hot-swap circuit 101, in one embodiment of the present invention, the power switch 1021 may be any one of the following: a mechanical switch; a magnetic induction switch; or a light induction switch.

[0066] In the implementation mode where the power switch 1021 is a magnetic induction switch, the pluggable module 20 is improved accordingly in the embodiment of the present invention, that is, a magnetic material body 203 is further provided on the pluggable module 20. Fig.12 As shown, Fig.12 The third partial structural diagram of the hot-swap-supporting device provided by the embodiment of the present invention is shown in FIG.

[0067] When any pluggable module 20 is inserted into or removed from a slot 102, the magnetic material body 203 contacts the power switch 1021, triggering the power switch 1021 to close; when any pluggable module 20 is fully inserted into or fully removed from a slot 102, the magnetic material body 203 disengages from the power switch 1021, triggering the power switch 1021 to open.

[0068] In an optional implementation, the magnetic induction switch may be, but is not limited to, a Hall sensor. The following will take the Hall sensor as an example to introduce the change of the on and off state of the Hall sensor during the insertion process. For an intuitive understanding, please refer to Fig.13 , Fig.13 Another schematic diagram of the insertion process of the pluggable module 20 provided in an embodiment of the present invention is shown in FIG. Fig.13 The rectangular notch 201 in the pluggable module 20 is omitted.

[0069] When the pluggable module 20 is not completely inserted into the slot 102 , the magnetic material body 203 is not in contact with the Hall sensor, so the Hall sensor remains in the disconnected state. Meanwhile, the power receiving contact 202 is not in contact with the power supply output terminal 1011 .

[0070] When the pluggable module 20 is inserted, the magnetic material body 203 comes into contact with the Hall sensor, and the Hall sensor is then switched to a closed state, thereby triggering the start of the hot-swap circuit 101. At this time, the power receiving contact 202 also comes into contact with the power supply output terminal 1011, and the hot-swap circuit 101 starts to supply power to the pluggable module 20 in a slow and steady manner.

[0071] As the insertion operation continues, the magnetic material body 203 will gradually leave the contact area of ​​the Hall sensor, causing the Hall sensor to switch back to the open state from the closed state, thereby triggering the shutdown of the hot plug circuit 101. Once the hot plug circuit 101 is shut down, the pluggable module 20 will stop being powered.

[0072] In contrast to the insertion process, the unplugging process of the pluggable module 20 follows the following steps: When the pluggable module 20 is unplugged, the magnetic material body 203 on the pluggable module 20 contacts the Hall sensor switch, which triggers the Hall sensor to close. At this time, the hot-swap circuit 101 is in a power supply state. The power receiving contact 202 of the pluggable module 20 contacts the power supply output terminal 1011 of the hot-swap circuit 101, ensuring that the module can receive the necessary power before being unplugged. As the unplugging action continues, the magnetic material body 203 of the pluggable module 20 gradually breaks away from the contact with the Hall sensor, which triggers the Hall sensor to disconnect again, and the hot-swap circuit 101 immediately cuts off the power supply to the pluggable module 20. After the power is cut off, the pluggable module 20 continues to be unplugged smoothly until it is completely out of the slot 102.

[0073] Through the above implementation, the embodiment of the present invention realizes accurate control of the hot-swap circuit 101. The system can timely cut off the hot-swap circuit 101 after the pluggable module 20 is fully inserted or fully pulled out, thereby avoiding unnecessary circuit energy consumption.

[0074] Further, from Fig.13 It can be seen that during the insertion process of the pluggable module 20, the magnetic material 203 gradually disengages from the contact Hall sensor switch, causing the hot-swap circuit 101 to stop supplying power to the pluggable module 20. In order to avoid power failure of the pluggable module 20, a corresponding power supply connector 103 is also provided on the frame 10 for each pluggable module 20, which is used to supply power to the pluggable module 20 when any pluggable module 20 is fully inserted into a slot 102.

[0075] It is understandable that during the insertion of the pluggable module 20, the hot-swap circuit 101 completes the power supply to the pluggable module 20, so that its power supply voltage rises from zero to the rated voltage. At this time, the module voltage is consistent with the voltage of the power supply connector 103, and the pluggable module 20 is inserted into the power supply connector 103 and powered by the power supply connector 103. After the pluggable module 20 contacts the power supply connector 103, it does not need power from the hot-swap circuit 101.

[0076] In one embodiment of the present invention, slot guides are also provided on the frame 10. These slot guides can provide precise guidance for the insertion and removal of the pluggable module 20, ensuring that the module can slide into and out of the slot steadily and smoothly.

[0077] Based on the above embodiments, the embodiment of the present invention further provides a physical display diagram of the frame 10, such as Fig.14 As shown, in the frame 10 provided by the embodiment of the present invention, in order to cooperate with the hot-swap circuit 101 to realize the power supply capability of the pluggable module 20, the slot 102 is fully improved, specifically including installing a power supply output terminal 1011 and a power switch 1021 on the side of the slot 102. The power supply output terminal 1011 contacts the power receiving contact 202 of the pluggable module 20 to realize the power supply of the hot-swap circuit 101 to the pluggable module 20; the power switch 1021 changes the open and closed state based on the position change of the magnetic material body 203 on the pluggable module 20 during the plugging and unplugging process, thereby realizing the purpose of starting or shutting down the hot-swap circuit 101.

[0078] It should be noted that in order to make the structure more concise and clear, Figures 2 to 14 The power receiving connector and the power circuit inside the pluggable module 20 are omitted. It should be pointed out that the power receiving connector is connected to the power circuit respectively. When any pluggable module 20 is inserted into a certain slot 102, the input end of the power circuit will contact the power supply output end 1011, and the hot-swap circuit 101 starts to supply power to the power circuit. When any pluggable module 20 is fully inserted into a certain slot 102, the power receiving connector will be connected to the power supply connector 103 on the frame 10, thereby realizing stable power supply to the power circuit. It ensures that reliable power support can be provided to the power circuit at different insertion stages.

[0079] In order to understand the hot-swap device 00 provided by the embodiment of the present invention as a whole, refer to Figure 1 , see Fig.15 , Fig.15 A schematic diagram of a connection relationship of a shared hot-swap circuit system in an embodiment of the present invention is shown. In this diagram, switch A1 to switch A NCorresponding to the power switch 1021 in the embodiment of the present invention, switch B corresponds to the lock switch 1022-3 in the embodiment of the present invention, and there is also a power supply output terminal 1011. It should be noted that although switch B and switches A1 to A1 are omitted in the figure, N The connection relationship between them is not shown, but they are interconnected in the actual system and work together to realize the power supply and locking functions of the hot-swappable module.

[0080] In summary, the hot-swappable device 00 provided in the embodiment of the present invention covers the dual improvements of the existing machine frame and the pluggable module. Specifically, a set of common hot-swappable circuits 101 are integrated in the machine frame 10 in the embodiment of the present invention, and the circuit can provide hot-swappable power supply functions for multiple pluggable modules 20. At the same time, a power supply output terminal 1011 is installed in the slot 102 of the machine frame 10, and a power receiving contact 202 is provided on the pluggable module 20. These components work together to realize the electrical connection between the hot-swappable circuit 101 and the pluggable module 20.

[0081] In addition, the slot 102 is also equipped with a power switch 1021, such as a magnetic induction switch, and correspondingly, the pluggable module 20 is provided with a magnetic material body 203, and the two cooperate with each other to jointly complete the opening or closing operation of the hot-swap circuit 101. Further, the slot 102 is also equipped with a locking device 1022, and the pluggable module 20 is correspondingly designed with a rectangular notch 201, and these designs jointly ensure that multiple pluggable modules 20 are prevented from being inserted or removed at the same time, thereby improving the safety and stability of the system.
