DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the scheme of the present invention, the embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are only for exemplary purposes and are not intended to limit the scope of protection of the present invention.

[0030] In order to ensure the safety of the servers in the cabinets, the cabinets in the related art generally adopt closed cabinets. In order to solve the problem of the servers being prone to overheating, the closed cabinets usually adopt liquid cooling systems to cool the servers. However, the door locks generally adopt simple mechanical locks or electronic latch locks. Such door locks generally cannot be uniformly managed and controlled, and often need to be opened manually by means of keys or electronic passwords.

[0031] However, in some special cases, manual operation is often not effective and timely. For example, a large number of cabinets issue high temperature warnings at the same time, or the cabinets are not equipped with keys or passwords are forgotten, and they are often unable to be unlocked. As for more complex control and unlocking methods such as remote control, unified management, and third-party verification, they are even more impossible to achieve. This leads to problems such as limited scope of application, limited usage scenarios, and insufficient intelligence and integration.

[0032] In order to solve the above technical problems, the embodiment of the present invention provides an unlocking control system for a liquid cooling cabinet. Figure 1 FIG. 1 is a schematic diagram of an unlocking control system for a liquid cooling cabinet according to an embodiment of the present invention. Figure 1 As shown, the system includes: a control module 11, a door lock 12, and a sensor module 13. The system is described in detail below.

[0033] The control module 11 includes a controller 110, which is connected to the door lock 12 to control the unlocking action of the door lock 12 according to instructions; the door lock 12 includes multiple unlocking modules 120, which work independently to unlock and are connected to the controller 110 and controlled by the controller 110; the sensor module 13 includes at least one sensor 130, which is set in the cabinet 2 and connected to the controller 110 to collect detection parameters in the cabinet 2 and transmit them to the controller 110.

[0034] The cabinet unlocking control system provided in this embodiment can receive the detection parameters of the sensor through the controller of the control module, and can issue an early warning according to the detection parameters, and automatically control the door lock unlocking and other actions, and then can communicate with remote devices and third-party application components such as access control through the controller to achieve the expansion and flexible use of unlocking methods. This solves the technical problem in the related art that cabinet unlocking relies on operators to manually unlock using passwords or keys, etc., which has great limitations in use.

[0035] The above-mentioned cabinet can be understood as a server cabinet. The cabinet of this embodiment can be a liquid cooling cabinet with a liquid cooling system. The liquid cooling cabinet is a fully enclosed structure. The cabinet door and the cabinet can be sealed by a seal to close the internal space of the cabinet. The liquid cooling system can be used to cool the interior of the cabinet.

[0036] It should be noted that the liquid cooling cabinet is only a preferred application scenario of this embodiment and should not be understood as a feature limitation of the solution. Specifically, the unlocking control system and method can automatically open the cabinet door lock and pop open the cabinet door when the temperature inside the liquid cooling cabinet is out of control, dissipate heat inside the cabinet, and perform emergency treatment.

[0037] The control module 11 is a functional module for performing control, and may include a remote device for issuing instructions, a host computer, or a third-party device such as an access control device or an RFID (Radio Frequency Identification) device.

[0038] The controller 110 mainly includes a communication module and a processing module. The communication module is used to communicate with the device that issues the command. The processing module processes the data according to the detection parameters transmitted by the sensor module and the received command according to a preset program, and performs the next action according to the final processing result, including early warning and control unlocking.

[0039] The controller 110 may be a processor such as an MCU (Micro Controller Unit) or a CPU (Central Processing Unit), or may be a control device including the processor and capable of performing data processing and communication control functions.

[0040] The controller 110 is connected to the door lock 12, which means that the controller 110 and the door lock can control the door lock 12 through control instructions. The corresponding door lock 12 will have at least one chip that can process control instructions, or at least one circuit device that can act according to simple instructions, such as a relay, a solenoid valve, a motor, etc.

[0041] The door lock 12 can be understood as a lock device set at the joint between the cabinet and the cabinet door. Generally speaking, the door lock 12 is divided into at least two parts, a first part fixed on the cabinet door, and a second part fixed on the cabinet. The two parts are independent of each other when the cabinet door is opened. When the cabinet door is locked, it is fixed through a connecting medium.

[0042] The connection medium may be a mechanical component, electromagnetic force, etc. The mechanical component may be a movable mechanical part, such as a latch, disposed on the first part or the second part. When locking, the mechanical part is matched with the other part to form a locking structure, so that the movement of the cabinet door in at least one direction is restricted.

[0043] In this embodiment, the door lock 12 includes a plurality of unlocking modules 120, which work independently to unlock, and the unlocking methods can be the same or different. The unlocking modules 120 are connected to the controller 110 and controlled by the controller 110. This is to ensure that the door lock 12 is effectively unlocked when it needs to be unlocked.

[0044] The unlocking module 120 can be understood as a circuit or device that can realize the corresponding unlocking action. For example, the door lock 12 is an electronic bolt lock, and its principle is to control the insertion and withdrawal of the bolt through an electromagnetic device to realize locking and unlocking.

[0045] For the electronic bolt rope, the above-mentioned multiple unlocking modules 120 can be two electronic lock structures, or one electronic lock and one mechanical lock. The mechanical lock can directly act on the bolt to achieve unlocking.

[0046] Theoretically, if the space allows and the cost is not taken into consideration, the number of unlocking modules 120 can be further increased. The more unlocking modules 120 there are, the higher the accuracy and reliability of the door lock 12 being unlocked by the controller. The fewer unlocking modules 120 there are, the lower the accuracy and reliability of the door lock 12 being unlocked by the controller.

[0047] Considering that the electronic lock and mechanical lock in the related art are generally simple in structure and have a high failure rate when working alone, in order to reduce the space occupied by the door lock and take into account both the cost and the reliability of control, two unlocking modules 120 are preferably used in this embodiment.

[0048] Furthermore, in order to prevent the same unlocking module 120 from failing at the same time due to a fault caused by an external environment, for example, failure of an electronic lock caused by a change in an external magnetic field will cause failure of some or even all electronic locks in the unlocking module 120. In this embodiment, one of the two unlocking modules 120 is preferably an electronic lock and the other is a mechanical lock, so as to further improve the effectiveness and reliability of unlocking the door lock.

[0049] The sensor module 13 includes at least one sensor 130, which can be understood as a device capable of obtaining detection parameters of the cabinet, and can be a dedicated sensor for detection, such as a temperature sensor, a humidity sensor, a temperature and humidity integrated sensor, a smoke sensor, a water immersion sensor, a smoke sensor, and the like.

[0050] The sensor 130 may also be a related device having other functions and may also be used for detection, such as a voltage acquisition circuit, a current acquisition circuit, etc., which can realize other circuit functions such as filtering and voltage division, and can also collect detection parameters of the circuit.

[0051] The sensor 130 is disposed in the cabinet 2 and connected to the controller 110 to collect detection parameters in the cabinet 2 and transmit the parameters to the controller 110 .

[0052] In this embodiment, the detection parameters include at least one of the following: temperature parameter, humidity parameter, smoke concentration, and water immersion height.

[0053] By receiving the detection parameters collected by the sensor module 13 through the control module 11 and making corresponding instructions in combination with the external communication device, the unlocking instruction is sent to the door lock 12, so as to realize the door lock control in various scenarios and needs.

[0054] As an optional embodiment, the unlocking control system also includes: a door opening module 14; the door opening module 14 includes a door push mechanism 140, and / or an elastic hinge; the door push mechanism 140 is installed on the cabinet and contacts the inner side of the cabinet door of the cabinet 2. When the door lock 12 is unlocked, the cabinet door is pushed open so that the opening angle of the cabinet door reaches at least a preset angle; the elastic hinge is arranged on the installation position of the cabinet door and the cabinet 2. When the door lock is unlocked, the cabinet door is pushed open so that the opening angle of the cabinet door reaches at least a preset angle.

[0055] The door opening module 14 can be understood as a door that can be effectively opened after the door lock 12 is unlocked, rather than remaining in its original state. This is particularly important in scenarios where no one is unlocking the door. If there is no one, the door needs to be unlocked. For example, if the temperature inside the cabinet is too high, it needs to be unlocked to dissipate heat. In this case, the cabinet door needs to be fully opened to achieve the desired heat dissipation effect.

[0056] The purpose of unlocking is actually to open the door. A door opening module 14 can automatically open the door after unlocking. On the one hand, the degree of automation is higher, and on the other hand, the opening and closing state of the door can be more clearly determined, which is convenient for making corresponding processing operations.

[0057] The door opening module 14 can be a door lifting mechanism 140 and / or an elastic hinge. The door lifting mechanism 140 and the elastic hinge have similar principles, that is, when the cabinet door is closed, the elastic member stores energy, and then when the cabinet door is opened, the elastic member converts the elastic force into a pull or rotation force on the cabinet door.

[0058] The difference between the top door mechanism 140 and the elastic hinge is that the top door mechanism 140 is generally only fixed on the cabinet and is not connected to the cabinet door. When the cabinet door is closed, the cabinet door contacts the top door mechanism 140 and compresses it to store energy. After the cabinet door is opened, the cabinet door is pushed open by the top door mechanism 140. When the opening angle of the cabinet door exceeds a certain angle, it will be separated from the top door mechanism 140.

[0059] The elastic hinge needs to be fixedly connected to both the cabinet and the cabinet door. Its main function is to hinge the polar rail and the cabinet door, but an elastic part is added to the hinge structure to store energy when the cabinet door is closed, and apply an opening force to the cabinet door after it is opened.

[0060] As an optional embodiment, Figure 4 FIG. 1 is a schematic diagram of a top door mechanism according to an embodiment of the present invention. Figure 4As shown, the top door mechanism 140 of this embodiment includes: a mounting body 141, a sequencer 142; the sequencer 142 is rotatably mounted on the mounting body 141, and the mounting body 141 is fixed on the cabinet 2; the sequencer 142 includes two cranks 143, one end of the two cranks 143 is hinged by an elastic member, and the other end of the two cranks 143 is provided with a roller 144.

[0061] The sequencer 142 is generally applied to fireproof doors, mainly for double-opening doors, and can make the two doors close in sequence in order to prevent the two doors from being stuck together. This embodiment applies it to cabinet doors, which can be directly purchased to reduce costs.

[0062] like Figure 4 As described above, the sequencer 142 includes two cranks 143, one end of the two cranks 143 is hinged by an elastic member, and the other end of the two cranks 143 is provided with a roller 144. When the cabinet door is closed, the two cranks 143 are compressed and retracted into the above-mentioned installation body 141. When the cabinet door is opened, one of the cranks 143 will pop out, and the other crank 143 will move slightly and basically stay in the installation body 141.

[0063] The main function of the installation body 141 is to fix the sequencer on the cabinet to avoid directly fixing the sequencer on the cabinet, which may cause damage to the cabinet and make subsequent maintenance difficult. The shape and structure of the installation body 141 can be deformed or changed at any time according to the actual physical space. This embodiment will not be described in detail here.

[0064] Therefore, in theory, the sequencer 142 can also be directly fixed to the cabinet by means of bolts or other fixing parts.

[0065] As an optional embodiment, Figure 5 Schematic diagram of a door lock according to an embodiment of the present invention. Figure 5 As shown, the unlocking module 120 includes at least one of the following: an electronic unlocking component 121, a mechanical unlocking component 122; the electronic unlocking component 121 includes a mounting portion 1211, an electromagnetic component, and a latch 1212; the mounting portion 1211 is mounted on the cabinet door of the cabinet 2; the electromagnetic component is fixed on the mounting portion 1211 and is connected to the controller 110; the latch 1212 is arranged on the mounting portion 1211 and can be movably inserted or withdrawn from the locking portion of the cabinet 2 that cooperates with the cabinet door.

[0066] The electronic unlocking component can be understood as a component that can use electromagnetic effect to control unlocking, or it can be an electronic bolt lock including the above component. In principle, the electromagnetic device generates a magnetic field when powered on, attracting or repelling the bolt, causing the bolt to move, thereby achieving unlocking or locking.

[0067] In this embodiment, the latch of the electronic lock can be retracted in the initial state, that is, when the electromagnetic part is powered off, the latch is retracted and the door lock is unlocked. When powered on, the latch is opened to lock the door, which can prevent the unlocking system from failing when the controller loses power.

[0068] Especially when the temperature rises due to a failure of the cabinet's heat dissipation module, the control module is located on the top of cabinet 2 and is easily ineffective due to high temperature. At this time, the unlocking system cannot be used. On the one hand, it will cause the unlocking to fail to respond in the emergency scenario of the failure and temperature rise, and on the other hand, it will cause the unlocking system to lose control.

[0069] When the electromagnetic component is powered off, the latch retracts, which can be achieved by superimposing the magnetic field of the permanent magnet and the electromagnetic component, or by using a mechanical reset structure and the electromagnetic component.

[0070] The permanent magnet can be set to attract / repel the bolt, so that the bolt is in a retracted state relative to the door lock. The electromagnetic component can be set to generate a magnetic field in the opposite direction to the magnetic field of the permanent magnet. After power is turned on, the magnetic field generated by the electromagnetic component is superimposed on the magnetic field of the permanent magnet, which can weaken the force of the permanent magnet on the bolt or even reverse the direction, thereby realizing the bolt popping open and locking.

[0071] The mechanical reset structure may be an elastic member, which acts on the bolt so that the bolt can be in a retracted state when there is no magnetic field of the electromagnetic member. By powering on the electromagnetic member, the elastic force of the elastic member is offset, so that the bolt can automatically pop out and lock. This realizes the above-mentioned action of the bolt retracting and unlocking when the electromagnetic member is powered off, and the bolt popping out and locking when the electromagnetic member is powered on.

[0072] The mounting portion 1211 is mounted on the cabinet door of the cabinet 2, and its main function is to fix the components to be mounted on the cabinet door on the cabinet door. The mounting portion 1211 can form an internal space to install the electromagnetic component and / or the latch 1212.

[0073] The mounting portion 1211 may also be fixed in a manner according to actual installation conditions, such as screw fixing, gluing, welding, etc. The shape of the mounting portion 1211 may also be adjusted according to the actual space inside the cabinet or the requirements of the internal electromagnetic components and / or the latch 1212.

[0074] The electromagnetic component is fixed on the mounting portion 1211 and connected to the controller 110. That is, the electromagnetic component can be controlled by the controller 110 to operate. In actual circuits, it can be directly connected or indirectly connected through some necessary components.

[0075] The latch 1212 is disposed on the mounting portion 1211 and can be movably inserted or withdrawn from the locking portion of the cabinet 2 that cooperates with the cabinet door. The latch can have various shapes and mounting structures. For example, a bar-shaped latch can be slidably mounted on the mounting portion 1211. A fan-shaped latch can be rotatably mounted on the mounting portion 1211.

[0076] It can also be an annular bolt, and the movement mode when locking or unlocking can be determined according to the structure of the door lock matching the annular bolt, so as to select the connection installation form. In this embodiment, the more important thing is to realize the electronic lock function.

[0077] As an optional embodiment, Figure 5 As shown, the mechanical unlocking assembly 122 includes a key unlocking component 1221, a paddle rod 1222, and a connecting rod mechanism 1223; the connecting rod mechanism 1223 is connected to the latch pin 1212, and the paddle rod 1222 is fixed on the key unlocking component 1221, and is configured to rotate and act on the connecting rod mechanism 1223 when the key unlocking component 1221 is unlocked, so that the connecting rod mechanism 1223 pulls the latch pin 1212 to unlock.

[0078] The mechanical unlocking assembly 122 can be understood as a mechanical lock core that can be unlocked with a key, and the key can rotate the mechanical lock core according to the mechanical lock core when the key is correct. The mechanical unlocking assembly 122 can also be a component including a mechanical lock core, which is installed on the cabinet door and supports mechanical unlocking.

[0079] In other embodiments, the mechanical unlocking component 122 may be a component that unlocks using a non-electromagnetic mechanical principle. That is, the mechanical unlocking component 122 may also be configured to be connected to the controller 110 on the basis of key opening, and may be unlocked according to the instructions of the controller 110.

[0080] When the mechanical unlocking component 122 is unlocked by a separate key, the electronic lock can be unlocked by the key in an emergency scenario. When the mechanical unlocking component 122 is unlocked by the key and the controller 110 can unlock, the electronic lock can be unlocked. In an emergency scenario where there is no key, authorization can be obtained through remote communication to achieve automatic control unlocking.

[0081] As an optional embodiment, it also includes: a rack 15; some equipment of the control module, fixed on the rack 15, and the rack 15 is slidably installed on the top of the cabinet 2 through the slide rails of the cabinet 2, wherein some equipment includes a controller 110; the rack 15 is installed on a universal slide rail, and the universal slide rail is the same as the slide rail for installing the machine tray of the cabinet 2; the slide rail is fixed on the top layer of the cabinet 2, and the upper top cover of the cabinet above the top layer is provided with a heat dissipation hole 151.

[0082] Figure 2 is a schematic diagram of a cabinet structure according to an embodiment of the present invention, Figure 3 for Figure 2 The schematic diagram of the cabinet A view is shown in FIG. Figure 2 and Figure 3 As shown, the controller 110, power supply components, wiring terminals, various IO interfaces and other devices can be installed on the rack 15. Heat dissipation components, wire management troughs, fixed rails and other structures can also be adaptively set to make the equipment on the rack 15 easy to maintain and inspect.

[0083] The rack 15 is slidably installed on the top of the cabinet 2 through the slide rails of the cabinet 2 to facilitate heat dissipation. The power consumption of the control 110 is very small compared to the server, and there is no need to use a server-specific liquid cooling system, which can simplify the liquid cooling system and reduce costs.

[0084] The rack 15 is mounted on a universal slide rail, which is the same as the slide rail on which the machine tray is mounted in the cabinet 2, for the convenience of maintaining the equipment on the rack. The slide rail can be used to draw the rack out after the door is opened, exposing the equipment on the rack outside the cabinet door for easy maintenance and inspection.

[0085] The slide rails are fixed to the top layer of the cabinet 2 to place the rack on the top of the cabinet, and the upper cover of the cabinet above the top layer is provided with heat dissipation holes 151 to facilitate heat dissipation and improve the working reliability and safety of the control module.

[0086] As an optional embodiment, the control module also includes at least one of the following: an access control component, a heat dissipation component, and a power supply component; the access control component is connected to the controller 110, and when the access control component senses the corresponding access control, it sends an unlock message to the controller 110; the heat dissipation component is installed at a position corresponding to the heat dissipation hole 151 on the rack, so that when the rack 15 is retracted into the cabinet 2, the heat dissipation component is opposite to the heat dissipation hole 151; the power supply component is installed on the rack 15 and connected to the controller.

[0087] The access control component can realize the function of unlocking the cabinet door by access control to meet more complex emergency scenarios. The heat dissipation component can be a component for assisting heat dissipation, such as a fan, a liquid cooling system, etc. It is arranged relative to the heat dissipation hole 151 to further improve the heat dissipation effect.

[0088] The above power supply components are used to independently power the controller and other devices of the control module to make their working stability higher. The power supply components can have functions such as circuit protection and backup power supply, and can realize power supply strategy implementation and management independently or with the controller.

[0089] An embodiment of the invention further provides an unlocking control method for a liquid cooling cabinet, which is applied to the unlocking control system of the above-mentioned liquid cooling cabinet. Figure 6Flow chart of a method for controlling unlocking a liquid cooling cabinet according to an embodiment of the present invention. Figure 6 As shown, the method comprises the following steps:

[0090] Step S601, receiving detection parameters of a sensor installed in the cabinet;

[0091] Step S602, comparing the detection parameter with the first parameter threshold, and triggering an alarm program to sound an alarm in a preset alarm mode when the detection parameter exceeds the first parameter threshold;

[0092] Step S603, when the detection parameter reaches a preset condition, the door lock of the cabinet is controlled to be unlocked, wherein the preset condition includes a first condition corresponding to the detection parameter and a second condition corresponding to a preset unlocking authority.

[0093] The cabinet unlocking control method provided by the embodiment of the invention can receive the detection parameters of the sensor through the controller of the control module, and can issue an early warning according to the detection parameters, and automatically control the door lock unlocking and other actions, and then can communicate with remote devices and third-party application components such as access control through the controller to achieve the expansion and flexible use of the unlocking method. This solves the technical problem that the cabinet unlocking in the related art relies on the operator to manually unlock using a password or key, which has great limitations in use.

[0094] The above method can be understood as a method for unlocking and managing the cabinet status in an unmanned scenario, and mainly realizes unlocking and management based on multiple detection parameters collected by sensors of the sensor assembly.

[0095] However, it should be noted that there are many types of detection parameters, including but not limited to temperature, humidity, smoke concentration, water immersion height, etc. Different detection parameters can, on the one hand, issue an early warning based on the corresponding values. That is, when the detection parameter exceeds the first parameter threshold, an early warning can be issued.

[0096] For example, if the temperature is higher than the corresponding temperature threshold, it means that the server is overloaded and the cooling system cannot keep up with the cooling efficiency, so an early warning can be issued. If the humidity is higher than the corresponding humidity threshold, it means that water has entered the cabinet or the cooling system has leaked, so an early warning can be issued. If the smoke concentration is higher than the corresponding threshold, it means that smoke is generated, and if the water immersion height exceeds the corresponding threshold, it means that the water in the cabinet is too deep, so an early warning can be issued.

[0097] When the corresponding preset conditions are met, the cabinet door can be unlocked. For example, if the temperature is too high for a long time and reaches the corresponding time threshold, or the temperature reaches a higher temperature threshold, the cabinet door can be unlocked to dissipate heat. Similarly, high humidity, water immersion, or smoke can all be used to unlock the cabinet door in different scenarios. These emergency operations can all be achieved through the controller.

[0098] As an optional embodiment, the method also includes: sending the detection parameters to a remote device, wherein the remote device includes a visualization interface and a data analysis algorithm for displaying and / or analyzing the detection parameters; receiving an unlock message sent by the remote device; responding to the unlock message, controlling the door lock to unlock; and / or, when the access control component senses the corresponding access control, receiving an unlock message sent by the access control component; responding to the unlock message, sending an unlock instruction to the door lock, and controlling the door lock to unlock.

[0099] The remote device can communicate with the controller 110 and remotely exchange data and issue instructions to achieve remote control unlocking of the cabinet door.

[0100] As an optional embodiment, the detection parameters include at least one of the following: temperature parameters, humidity parameters, smoke concentration, and water immersion height; the first condition includes at least one of the following: whether the type of the detection parameter is an automatic unlocking type; the duration of the detection parameter exceeding the first parameter threshold reaches a preset time threshold; the detection parameter exceeds the second parameter threshold, wherein the second parameter threshold is higher than the first parameter threshold; the second condition includes at least one of the following: whether the unlocking authority of the corresponding cabinet is to allow active unlocking; whether the unlocking authority of the corresponding cabinet is to allow active unlocking under the corresponding risk level, wherein the risk level is determined based on the value and type of the detection parameter.

[0101] Whether the type of the above detection parameter is the type of automatic unlocking, that is, whether the detection parameter supports automatic unlocking, some sensors only detect whether the cabinet door is closed. For example, the micro-motion sensor set in the door opening mechanism can determine whether the cabinet door is effectively closed by detecting the position of the sequencer.

[0102] This type of detection parameter does not support automatic unlocking, and naturally will not trigger the corresponding unlocking program. If it is a type of detection parameter such as temperature and humidity, it needs to be associated with automatic unlocking to automatically unlock under certain conditions.

[0103] The duration of the detection parameter exceeding the first parameter threshold reaches the preset time threshold; the detection parameter exceeds the second parameter threshold, where the second parameter threshold is higher than the first parameter threshold. In other words, after a period of warning, the situation has not improved, and / or the detection parameter has reached the dangerous second threshold. If the unlocking is not performed, it may cause damage to the device, so it is necessary to control the unlocking in time.

[0104] In the second condition, whether the unlocking permission of the corresponding cabinet is to allow active unlocking. That is, the data security level of the servers in some cabinets is very high, and it is set to not be leaked even if it is damaged. In this case, the cabinet may not be allowed to be unlocked. Or it can be understood that the detection parameters of the current scene still cannot meet the unlocking permission. Therefore, the unlocking will not be triggered.

[0105] Whether the unlocking permission of the corresponding cabinet allows active unlocking at the corresponding risk level, where the risk level is determined according to the value and type of the detection parameter. In other words, different cabinets can be set with different unlocking permissions. Different unlocking permissions can be set with corresponding risk levels. Active unlocking will be triggered only when the corresponding risk level is reached, otherwise unlocking will not be triggered.

[0106] It should be noted that this embodiment also provides an optional implementation, which is described in detail below.

[0107] This embodiment proposes a sealed cabinet solution that can automatically open the cabinet door based on the temperature inside the cabinet, wherein the 1U modular rack is installed using a universal slide rail, which can achieve standard installation of various cabinet models, reduce installation accuracy requirements and customization needs, and achieve cost reduction and efficiency improvement.

[0108] The control module 11 including some equipment of the controller 110 can be installed on a 1U standard rack. Combined with the door lock 12 and the sensor module 13 in the cabinet, the environmental data collection and data transmission in the cabinet and the output of the intelligent unlocking system control execution command can be realized.

[0109] The intelligent unlocking system of this embodiment can cooperate with unattended data centers to realize IT cabinet door authorization opening, or remote opening, or the cabinet door needs to be opened quickly and automatically when the set conditions (such as overheat protection in the cabinet) are met, or it can be opened manually and mechanically locally. Compared with other existing solutions, it has the advantages of high security, high reliability, low cost and easy installation.

[0110] This implementation method makes design optimization on the standard cabinet, and the specific structural design is as follows: During the specific implementation, the standard cabinet size used is 600*1200*2000mm (excluding casters and feet), the frame size is 600*1154*2000mm, and the frame material is carbon steel sheet metal.

[0111] like Figures 2 to 3As shown, cabinet 2 includes a cabinet frame, a top plate, a bottom plate, a single-opening closed front cabinet door, a double-opening closed rear cabinet door, anchor casters, and cabinet double-sided side doors. PDU (Power Distribution Unit) mounting parts and rear vertical cable management racks, and liquid-cooled VCDU (Voltage Conditioning and Distribution Unit) mounting kits are also provided inside the cabinet for installing a controllable liquid cooling system. Among them, the closed cabinet door refers to the sealing foam provided by the foaming process to achieve cabinet sealing.

[0112] The gaps inside the cabinet are sealed with 1U metal quick-open blind plates. Universal rails and heavy-duty trays are installed inside the cabinet to place IT network equipment, intelligent cooling modules, and liquid cooling distribution units (CDU).

[0113] Temperature and humidity integrated sensors are installed at a total of 6 locations in the upper, middle and lower parts of the hot and cold channels in the front and rear of the cabinet (specifically, three locations are evenly set from top to bottom on the right side of the cabinet front frame, namely T1, T2, and T3, and three locations are evenly set from top to bottom on the right side of the rear frame, namely T4, T5, and T6). The temperature and humidity integrated sensor is connected in series to the control module device on the 1U rack through an RS485 network cable to monitor the temperature and humidity of the microenvironment in the cabinet in real time and objectively.

[0114] The above temperature and humidity integrated sensor will transmit the detected temperature and humidity values ​​to the control module device in real time, and display them intuitively in a graphical form on the monitoring interface connected to the control module 11. The administrator can see the actual temperature and humidity values ​​of each point in the server cabinet in real time.

[0115] Once the actual temperature and humidity values ​​in cabinet 2 exceed the limit, the system triggers an alarm, and even triggers emergency processing when certain judgment conditions are met, for example, the cabinet door automatically pops open. The temperature and humidity values ​​in the computer room over a period of time can also be plotted as a historical curve for intuitive display, which is convenient for management personnel to analyze and view afterwards, providing a basis for subsequent management.

[0116] A smoke sensor is installed on the top of the cabinet to detect the smoke concentration in the air duct inside the cabinet, so as to provide early warning of fire. A water immersion sensor is installed at the bottom of the cabinet to detect whether there is any leakage in the system pipeline under the cabinet.

[0117] like Figures 2 to 3 As shown, a 1U rack is installed at the top support rail of the cabinet, and a control module device is set to realize the collection and data transmission of the cabinet environment data and the output of the intelligent unlocking system control execution command.

[0118] In this embodiment, the door opening module 14 is installed on the front of the acquisition control module, that is, the front cabinet door, and is fixed to the front column of the cabinet with a common M5 screw. Similarly, the door opening module 14 of the rear cabinet door is fixed to the rear column of the cabinet through a sheet metal adapter.

[0119] If the installation location is limited by the fixing space after installing the PDU, you can also use the matching hole method to fix the 1U pop-up door control module on the top cover of the cabinet.

[0120] like Figure 4 As shown, the structural feature of the door opening module 14 is that its bottom and back are hole structures, which is convenient for controlling the air intake at the module equipment end and ensuring the heat dissipation and air intake requirements of the switching power supply module.

[0121] In order to ensure that the cabinet door can be opened to 90° after opening, a "7-type" sequencer 142 is used to maximize the ventilation area of ​​the cabinet 2, so that the cabinet door can remain in a normally open state without external force. When the door is closed, the sequencer 142 is in a spring power storage state, and a crank 143 of the sequencer 142 contacts the limit micro-motion sensor, thereby determining whether the cabinet door is in a closed state, that is, a closed cabinet state.

[0122] Among them, two limit micro-motion sensors are arranged in the door opening module 14 for backup to prevent the limit micro-motion sensor failure from causing the pop-up door control logic to misjudge the automatic door opening. The limit micro-motion switches installed at the front and rear of the cabinet 2 have the same structure, the difference is that the rear module is shorter.

[0123] The cabinet door lock structure uses the standard lock, and the original standard lock tongue is replaced by a special-shaped paddle lever. Install a wedge-shaped latch electronic lock, one wedge-shaped latch electronic lock is installed on the front door, and one electronic lock is installed on each of the rear double doors.

[0124] The wedge-shaped latch electronic lock has a guiding function due to its wedge-shaped structure, which reduces the installation accuracy requirements for the cabinet door, reduces the installation difficulty, and the compression degree of the cabinet sealing foam is more controllable.

[0125] The initial state (power failure) of the above-mentioned wedge-shaped latch electronic lock is the state where the lock tongue is retracted, and the lock tongue pops out after power is turned on. This is convenient for opening the cabinet door first to ensure the safety of the equipment when the intelligent unlocking system loses power, such as when the electronic lock cable is damaged or the power supply contact is poor, or when the 1U acquisition control module equipment loses power.

[0126] like Figure 5 As shown, the tail rod of the wedge-shaped latch electronic lock has a latch pin 1212, and the connecting rod mechanism 1223 includes a connecting rod 1 and a connecting rod 2. The connecting rod 2 and the connecting rod 1 are connected by a pin shaft 1, and the connecting rod 2 and the standard lock are connected by a washer shaft (i.e., pin shaft 2) and a fixing hole of the standard lock. The washer shaft is an annular step structure, and its step and the connecting rod 2 through hole form a pin hole to form a crank slider structure.

[0127] Because the bolt stroke is 10mm, and in order to take into account the 90° rotation of the standard lock handle, the special-shaped paddle can realize the paddle connection rod 2. At the same time, in this state, when closing the door, there is no dead point caused by the handle paddle rod being restricted.

[0128] At the same time, when the standard handle is in the locked state, the swing of the connecting rod will not interfere with the paddle or other cabinet door mechanisms when the wedge-shaped pin electronic lock is automatically opened and closed. Therefore, the position of the pin 1 point is selected at the left point near the intersection of the stroke circle of the initial and final states. Here, the swing amplitude of the connecting rod 2 is small during the tail rod reset and working stroke, which is convenient for eliminating the dead point range when rotating the standard lock handle to close the door.

[0129] The above-mentioned special-shaped paddle lever is a 2mm sheet metal part, and its tail end is bent into a step with the same angle as the crank 2 in the open state. Its form is similar to a simplified version of a bicycle shift paddle.

[0130] like Figures 7 and 8 As shown, several working modes of the smart unlocking system are as follows:

[0131] Access unlocking mode: The operation of the cabinet door lock is the same for the front and back doors of the cabinet. In non-emergency situations, card swiping access control is used to facilitate intrusion monitoring management and recording, and protect equipment security and user data security. Specifically, the access control induction mode is adopted. When the access control key is placed in the induction area, the electronic lock will automatically open.

[0132] When closing, just close the door. When the controller determines that the door is closed, it will energize the wedge-shaped latch electronic lock, and the lock tongue will pop out to lock the door. The cabinet indicator light (green) will go out after the cabinet door is opened, and the indicator light will light up after the cabinet is locked.

[0133] Automatic pop-up emergency unlocking mode: When power outages, cooling component failure, and other faults occur, it can be reliably applied to unattended scenarios. The working logic of the self-pop-up emergency system is: when the control system detects that the temperature inside the cabinet is higher than the safety threshold K, and the cooling component partially fails / completely fails, the electronic lock is powered off and reset to the lock tongue retracted state, the sequencer 142 of the top door mechanism 140 is reset by the spring stored state, and the front roller of the sequencer moves relative to the cabinet door, causing the cabinet door to automatically pop open.

[0134] Specific as Figure 8 As shown, when it is determined that the cabinet door is closed, determine whether the cabinet is loaded. If there is a load, determine whether the temperature uniformity meets the requirements. If the temperature uniformity meets the requirements, determine whether it exceeds the temperature safety threshold K and lasts for Tmin. If so, control the door lock to unlock.

[0135] If the above cabinet is without load, there is no need to perform the high temperature triggered automatic pop-up emergency unlocking mode. If the temperature uniformity is not met, it means that the cabinet door may not be closed or there is a fault in the cooling system. Even if the lock is controlled, there may not be sufficient heat dissipation effect. This situation may involve other control programs, and there is no need to perform the high temperature triggered automatic pop-up emergency unlocking mode.

[0136] Whether the above-mentioned cabinet door is closed, whether the cabinet is loaded and whether the temperature uniformity meets the requirements can all be understood as prerequisites for high temperature triggering automatic pop-up emergency unlocking mode. If they are not met, the process of detecting whether the cabinet door is closed can be re-executed from the beginning.

[0137] Whether the cabinet is loaded can be determined by whether T3 is less than T6. This is because when the cabinet is loaded, due to the effect of the liquid cooling system, a temperature difference will occur on both sides of the temperature and humidity integrated sensor. In theory, it can also be determined by whether there is a temperature difference between T1 and T4, T2 and T5 at the same height.

[0138] Whether the temperature uniformity meets the requirements can be determined by whether the temperature difference between T1 and T3 exceeds the preset threshold value X. In theory, it can also be determined by whether the temperature difference between T4 and T6 exceeds the preset threshold value X.

[0139] After the high temperature triggers the automatic pop-up emergency unlocking mode, the control door lock is unlocked and the cabinet door pops open. At this time, the heat inside the cabinet can be dissipated to the external environment in a short time, relying on the residual cold capacity in the computer room space to provide response time for equipment failure repair, thereby ensuring the security of its internal IT equipment and user data. When a fire occurs in the equipment inside the cabinet, the intelligent unlocking system cooperates with the fire-fighting equipment to take fire-fighting actions.

[0140] After the self-locking system automatically opens the door, the door opening signal will enter the controller and send out an alarm message. After the maintenance personnel eliminate the on-site problems, they need to close the door manually.

[0141] Mechanical unlocking mode: When the electronic access control system has a software failure, this intelligent unlocking system can solve the current problem of the IT cabinet in the data center being unable to open. For example, when the electronic lock cannot be powered off, the crank slider structure in this solution is combined with the door lock's special-shaped paddle lever, and the key can be used to mechanically unlock the door in this state without being affected by any electronic or electrical failure.

[0142] Remote unlocking mode: It has the remote authorization control unlocking function, and sends the unlocking function authorization to the control module 12 through the host computer to execute the door opening logic.

[0143] like Figure 8 As shown, the above different working modes can be combined or used in combination according to actual needs. Figure 8In the figure, T1, T3, and T6 refer to the temperature values ​​collected by the temperature and humidity integrated sensors set at the corresponding positions, respectively. The temperature uniformity judgment X℃ can be set to 0~2℃, the over-temperature setting K℃ can be set to 28~32℃, and the duration T can be set to 1~3min.
