In data centers where intelligent inspection robots are becoming increasingly popular, in the above application scenarios, abnormal noise, gas leakage, indicator light status, etc. are all enclosed in the cabinets, affecting the normal use of the robot's detection sensors and cameras. Utility Model Content

[0003] The utility model discloses a cabinet which can be used in a robot inspection scene, and a cabinet door of the cabinet can be automatically opened and closed according to demand.

[0004] In order to achieve the above object, the utility model provides the following technical solutions:

[0005] A cabinet comprises: a cabinet body, an opening door structure, a closing door structure, a security structure and a monitoring unit;

[0006] The monitoring unit includes a first communication module, which is used to connect with the second communication module on the mobile device by signal to receive a door opening request or a door closing request sent by the second communication module;

[0007] The cabinet body includes a door frame and a cabinet door, and the door opening structure includes a door opening controller and a door opening drive mechanism; the door opening drive mechanism is connected to the cabinet door by transmission; the door opening controller is connected to the monitoring unit by signal, and is connected to the door opening drive mechanism by signal, and is used to trigger the door opening drive mechanism to open the cabinet door;

[0008] The door closing structure includes a switch and a door closing drive mechanism. The switch is arranged on a surface of the door frame facing the cabinet door and is connected to the monitoring unit signal for detecting the switch state of the cabinet door. The door closing drive mechanism is connected to the monitoring unit signal and is connected to the cabinet door transmission for closing the cabinet door and causing the cabinet door to trigger the switch.

[0009] The security structure is connected to the monitoring unit signal and is used to detect whether there is an obstacle within the movable range of the cabinet door.

[0010] In order to adapt to the use scenario of the intelligent inspection robot, the monitoring unit of the above cabinet includes a first communication module connected to the second communication module signal on a mobile device such as a robot. The mobile device can send a door opening request or a door closing request to the monitoring unit of the cabinet through the communication between the second communication module and the first communication module. The monitoring unit of the cabinet responds according to the corresponding request. Specifically, the cabinet includes a door frame and a cabinet door. The cabinet door has an open state and a closed state relative to the door frame. A switch is provided on the surface of the door frame facing the cabinet door. When the cabinet door is in a closed state, the cabinet door triggers the switch. When the cabinet door is in an open state, the switch is not triggered, so that the switch can detect the state of the cabinet door. The switch is connected to the monitoring unit signal inside the cabinet, and the state information of the cabinet door is sent to the monitoring unit. The monitoring unit responds to different operations according to the request received by the first communication module. For example, the monitoring unit receives a door opening request through the first communication module. The monitoring unit responds to the door opening request, generates a door opening control command and sends it to the door opening controller. The door opening controller controls the door opening drive mechanism to open the cabinet door to complete the automatic door opening operation. For another example, the monitoring unit receives a door closing request through the first communication module, and the monitoring unit generates a door closing control command in response to the door closing request and sends it to the door closing drive mechanism, and the door closing drive mechanism closes the cabinet door to complete the automatic door closing operation. The monitoring unit can also generate control information according to the state information of the cabinet door. For example, when the switch detects that the cabinet door is in an open state, the monitoring unit generates a door closing control command and sends it to the door closing drive mechanism, and the door closing drive mechanism drives the cabinet door according to the door closing control command until the cabinet door is in a closed state and triggers the switch. At this time, the switch detects that the cabinet door is closed, and sends the information that the cabinet door is in a closed state to the monitoring unit. The monitoring unit generates a stop command according to the closed state information and sends the stop command to the door closing drive mechanism, and the door closing drive mechanism stops driving to complete the automatic closing process of the cabinet door. In addition, in order to avoid obstacles such as people or robots in the closing process of the cabinet door, the cabinet is also provided with a security structure, which can detect whether there are obstacles such as people or robots in the range of the cabinet door, and send the information to the monitoring unit, and the monitoring unit controls the door opening drive mechanism or the door closing drive mechanism to stop driving in time to prevent safety accidents.

DETAILED DESCRIPTION

[0039] First, let me introduce the application scenario of this application: In order to improve the heat exchange efficiency of air conditioning and achieve energy saving in micro-module data centers, the cabinets will adopt the method of closed hot and cold channels. In order to form closed hot and cold channels, the cabinet doors can only use glass doors or solid sheet metal doors, and mesh doors or doorless solutions cannot be used; in the face of robot inspection scenarios, due to the obstruction of sheet metal doors and glass doors, the camera cannot capture the status inside the cabinet through the cabinet door. At the same time, abnormal noise, odor, leakage and other information are all sealed in the cabinet. The robot's own sound, gas, smoke and other sensors cannot normally obtain this information, resulting in the robot not being able to work normally, affecting the inspection business.

[0040] In addition, in the above application scenarios, in the case of high temperature, power outage and fire, the door will be opened to achieve heat dissipation and fire protection linkage. When facing a computer room where maintenance personnel are far away or a computer room that is not on duty 24 hours a day, for example, the air conditioner suddenly loses power and causes the cabinet to heat up. The cabinet door opens automatically, and then the air conditioner is powered on and operates normally. Since the cabinet door cannot be closed in time, the entire micro module cannot resume normal operation, seriously affecting the business of the micro module.

[0041] In addition, after the cabinet door is opened, it needs to be manually closed to reset, which is time-consuming. When the micromodule senses the fire signal, it will automatically open; after the fire is over, the operation and maintenance personnel need to close the cabinet doors one by one. If the module is long and there are many cabinets, it will seriously affect the work efficiency of the operation and maintenance personnel and the overall experience of the micromodule in the computer room.

[0042] Based on the above application scenarios, an embodiment of the present application provides a cabinet whose door can automatically open and close according to needs.

[0043] The following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" refers to two or more than two.

[0044] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0045] like Figures 1 to 5 As shown, the embodiment of the utility model provides a cabinet, including: a cabinet body 100, a door opening structure 500, a door closing structure 200, a security structure 300 and a monitoring unit 400; the monitoring unit 400 includes a first communication module 410, which is used to connect with the second communication module 710 on the mobile device 700 by signal to receive a door opening request or a door closing request sent by the second communication module 710; the cabinet body 100 includes a door frame 110 and a cabinet door 120, and the door opening structure 500 includes a door opening controller 510 and a door opening drive mechanism; the door opening drive mechanism is connected to the cabinet door 120 by transmission; the door opening controller 510 is connected to the monitoring unit 400 by signal, And it is connected to the door opening drive mechanism signal, used to trigger the door opening drive mechanism to open the cabinet door 120; the door closing structure 200 includes a switch 210 and a door closing drive mechanism 220, the switch 210 is arranged on the surface of the door frame 110 facing the cabinet door 120, and is connected to the monitoring unit 400 signal, used to detect the state of the switch 210 of the cabinet door 120; the door closing drive mechanism 220 is connected to the monitoring unit 400 signal, and is transmission connected to the cabinet door 120, used to close the cabinet door 120 and make the cabinet door 120 trigger the switch 210; the security structure 300 is connected to the monitoring unit 400 signal, used to detect whether there is an obstacle within the activity range of the cabinet door 120.

[0046] In order to adapt to the use scenarios of intelligent inspection robots, refer to Figure 5, the monitoring unit 400 of the cabinet includes a first communication module 410 connected to the second communication module 710 on the mobile device 700 such as a robot by signal, and the mobile device 700 can send a door opening request or a door closing request to the monitoring unit 400 of the cabinet through the communication between the second communication module 710 and the first communication module 410. The monitoring unit 400 of the cabinet responds according to the corresponding request. Specifically, the cabinet body 100 includes a door frame 110 and a cabinet door 120, and the cabinet door 120 has an open state and a closed state relative to the door frame 110. A switch 210 is provided on the surface of the door frame 110 facing the cabinet door 120. When the cabinet door 120 is in a closed state, the cabinet door 120 triggers the switch 210, and when the cabinet door 120 is in an open state, the switch 210 is not triggered, so that the switch 210 can detect the state of the cabinet door 120. The switch 210 is connected to the monitoring unit 400 inside the cabinet by signal, and the state information of the cabinet door 120 is sent to the monitoring unit 400. The monitoring unit 400 responds to different operations according to the request received by the first communication module 410. For example, the monitoring unit 400 receives a door opening request through the first communication module 410. In response to the door opening request, the monitoring unit 400 generates a door opening control command and sends it to the door opening controller 510. The door opening controller 510 controls the door opening drive mechanism to open the cabinet door 120, thereby completing the automatic door opening operation. For another example, the monitoring unit 400 receives a door closing request through the first communication module 410. In response to the door closing request, the monitoring unit 400 generates a door closing control command and sends it to the door closing drive mechanism 220. The door closing drive mechanism 220 closes the cabinet door 120, thereby completing the automatic door closing operation. The monitoring unit 400 can also generate control information based on the status information of the cabinet door 120. For example, when the switch 210 detects that the cabinet door 120 is in an open state, the monitoring unit 400 generates a door closing control command and sends it to the door closing drive mechanism 220. The door closing drive mechanism 220 drives the cabinet door 120 to move according to the door closing control command until the cabinet door 120 is in a closed state and triggers the switch 210. At this time, the switch 210 detects that the cabinet door 120 is closed and sends the information that the cabinet door 120 is in a closed state to the monitoring unit 400. The monitoring unit 400 generates a closing command based on the closing state information and sends the closing command to the door closing drive mechanism 220. The door closing drive mechanism 220 stops driving, completing the automatic closing process of the cabinet door 120. In addition, in order to prevent the cabinet door 120 from encountering obstacles such as people or robots during the closing process, the cabinet is also provided with a security structure 300. The security structure 300 can detect whether there are obstacles such as people or robots within the activity range of the cabinet door 120, and send the information to the monitoring unit 400. The monitoring unit 400 controls the door opening drive mechanism or the door closing drive mechanism 220 to stop driving in time to prevent safety accidents.

[0047] Therefore, the cabinet provided by the embodiment of the utility model can automatically open and close the door according to demand, can be suitable for robot intelligent inspection scenarios, and can close the door in time so that the entire micromodule can resume normal operation in time.

[0048] In some embodiments, the security structure 300 includes a first detection probe 310 and a second detection probe 320 . The first detection probe 310 is disposed on a surface of the door frame 110 facing the cabinet door 120 , and the second detection probe 320 is disposed on a surface of the cabinet door 120 facing away from the door frame 110 .

[0049] like Figure 3 and Figure 4 As shown, in order to prevent the cabinet door 120 from encountering obstacles such as people or robots during the closing process, a first detection probe 310 is further provided on the surface of the door frame 110 of the cabinet body 100 facing the cabinet door 120. The first detection probe 310 can detect whether there are obstacles such as people or robots within the moving range of the cabinet door 120 during the switching process from an open state to a closed state, and the first detection probe 310 is connected to the monitoring unit 400 by signal. When the first detection probe 310 detects that there is an obstacle within the moving range of the cabinet door 120, the information is sent to the monitoring unit 400. The monitoring unit 400 can promptly control the door closing drive mechanism 220 to stop driving the cabinet door 120 to close, thereby preventing safety accidents from occurring. In order to prevent the cabinet door 120 from encountering obstacles such as operation and maintenance personnel or inspection robots during the opening process, a second detection probe 320 is further provided on the surface of the cabinet door 120 of the cabinet body 100 facing away from the door frame 110. The second detection probe 320 can detect whether there are obstacles such as operation and maintenance personnel or inspection robots within the activity range of the cabinet door 120 during the switching process from a closed state to an open state, and the second detection probe 320 is connected to the monitoring unit 400 by signal. When the second detection probe 320 detects that there is an obstacle within the activity range of the cabinet door 120, the information is sent to the monitoring unit 400. The monitoring unit 400 can promptly prevent the cabinet door 120 from opening to prevent safety accidents.

[0050] One possible way to achieve this is as follows: Figure 2 As shown, the monitoring unit 400 is located inside the cabinet and close to the top of the cabinet. The switch 210 is connected to the monitoring unit 400 by signal. In order to reduce wiring, the switch 210 is set at the top of the door frame 110. Exemplarily, the switch 210 can be any one or more of a micro switch, a touch switch or a travel switch. Figure 3 As shown, the first detection probe 310 is disposed in the lower middle portion of the door frame 110 to facilitate detection of obstacles on the ground, including people, robots or other objects. For example, the first detection probe 310 may be an infrared probe or a camera. Figure 4As shown, the second detection probe 320 is disposed at the lower middle portion of the cabinet door 120 to facilitate detection of obstacles on the ground, including people, robots or other objects. Exemplarily, the second detection probe 320 can be an infrared probe or a camera.

[0051] In some embodiments, the first detection probe 310 and / or the second detection probe 320 is an infrared probe. The infrared probe adopts non-contact measurement to detect whether the robot or the operation and maintenance personnel are within the range of the door switch to prevent safety accidents.

[0052] In some embodiments, the door opening drive mechanism includes an electronic lock 520 and a pop-up opener 530; the door opening controller 510 is electrically connected to the electronic lock 520 for triggering the electronic lock 520; the electronic lock 520 is installed on the door frame 110 and the cabinet door 120 for providing the cabinet door 120 with a closing force toward the door frame 110; the pop-up opener 530 is installed on the door frame 110 and the cabinet door 120 for always providing the cabinet door 120 with a thrust away from the door frame 110, and when the electronic lock 520 is turned on, the closing force is greater than the thrust.

[0053] One possible way to achieve this is as follows: Figure 6 , Figure 7a and Figure 7b As shown, and refer to Figure 2 The door opening drive mechanism includes an electronic lock 520 and a pop-up opener 530; the electronic lock 520 is used to provide a closing force such as suction to the cabinet door 120 and the door frame 110, and the pop-up opener 530 is used to provide a thrust to the cabinet door 120 and the door frame 110. When the electronic lock 520 is turned on, i.e., powered on, the suction force is greater than the thrust, and the cabinet door 120 is in a closed state. When the electronic lock 520 is powered off, the suction force disappears, and the thrust of the pop-up opener 530 pushes the cabinet door 120 open. When the monitoring unit 400 receives the door opening request, it sends a door opening DO signal to the door opening controller 510, and the door opening controller 510 controls the electronic lock 520 to power off, the closing force disappears, and the cabinet door 120 is opened under the thrust of the pop-up opener 530.

[0054] In some embodiments, the electronic lock 520 includes an electromagnet 521 and an armature 522 , wherein the electromagnet 521 is fixed to the door frame 110 , and the armature 522 is fixed to the cabinet door 120 ; or, the electromagnet 521 is disposed on the cabinet door 120 , and the armature 522 is fixed to the door frame 110 .

[0055] In one possible implementation, refer to Figure 2 and Figure 3The electronic lock 520 includes an electromagnet 521 and an armature 522. The electromagnet 521 is fixed to the door frame 110, and the armature 522 is fixed to the cabinet door 120. When the electromagnet 521 is powered off, the suction force between the electromagnet 521 and the armature 522 disappears, and the cabinet door 120 can be opened under the action of the ejector 530. When the electromagnet 521 is powered on, the suction force between the electromagnet 521 and the armature 522 is greater than the thrust of the ejector 530, and the cabinet door 120 is tightly adsorbed on the door frame 110, closing the interior of the cabinet.

[0056] In some embodiments, the door opening controller 510 includes a relay 511, the coil of the relay 511 is electrically connected to the monitoring unit 400; the normally closed contact NC of the relay 511 is electrically connected to the electromagnet 521; the relay 511 is used to disconnect or connect the electrical circuit of the electromagnet 521 according to the control signal of the monitoring unit 400.

[0057] In one possible implementation, the door opening controller 510 further includes a relay 511, such as Figure 7a As shown, the relay 511 has a coil and a normally closed contact NC, a common contact COM and a normally open contact NO. The coil of the relay 511 is electrically connected to the monitoring unit 400. The monitoring unit 400 can control the coil to be energized or de-energized so that the common contact COM is connected to the normally closed contact NC or the common contact COM is connected to the normally open contact NO. The normally closed contact NC is connected to an electromagnet 521. When the cabinet door 120 is in a closed state, the common contact COM is connected to the normally closed contact NC, the electromagnet 521 is energized, and the electromagnet 521 attracts the armature 522 to provide a closing suction force for the cabinet door 120. The ejector 530 provides a thrust force to the cabinet door 120, and the suction force is greater than the thrust force. When the cabinet door 120 switches from a closed state to an open state, the common contact COM is connected to the normally open contact NO, the electromagnet 521 is powered off, the suction force between the electromagnet 521 and the armature 522 disappears, and the cabinet door 120 can be opened under the thrust of the ejector 530.

[0058] In some embodiments, the door opening drive mechanism includes at least two electronic locks 520, and the at least two electronic locks 520 are spaced apart along the height direction of the cabinet; and the electromagnets 521 in all the electronic locks 520 are connected in parallel and electrically connected to the normally closed contact NC of the relay 511.

[0059] In order to ensure the closure of the cabinet door 120, refer to Figure 2 and Figure 3 , two electromagnets 521 are arranged on the door frame 110, one electromagnet 521 is close to the top of the cabinet, and the other electromagnet 521 is close to the bottom of the cabinet. Of course, more than two electromagnets 521 can also be arranged. Figure 7aAs shown, two electromagnets 521 are connected in parallel and electrically connected to the normally closed contact NC, so that one relay 511 can control the on and off states of the electromagnets 521 of all electronic locks 520 .

[0060] In some embodiments, the cabinet includes two cabinet doors 120 , and each of the two cabinet doors 120 is correspondingly provided with an opening door structure 500 and a closing door structure 200 .

[0061] In one possible implementation, the cabinet may include two cabinet doors 120, one of which may be the front door of the cabinet, and the other of which may be the rear door of the cabinet. Correspondingly, the front door is provided with a matching door opening structure 500 and door closing structure 200, so that both the front and rear doors of the cabinet can be opened and closed automatically. Figure 7b As shown, the door opening controller 510 has two relays 511, one of which controls the on and off of two electromagnets 521 on the front door. Figure 7b As shown in FIG. 5F, another relay 511 controls the on / off of two electromagnets 521 on the rear door. Figure 7b As shown in B.

[0062] In order to avoid occupying the internal space of the cabinet, the door closing drive mechanism 220 is arranged outside the cabinet 100. In some embodiments, the door closing drive mechanism 220 is located on the top of the cabinet 100 to facilitate signal connection with the monitoring unit 400 inside the cabinet.

[0063] In some embodiments, specifically, the door closing drive mechanism 220 includes a motor 221 and a connecting rod assembly 222 that is transmission-connected to the motor 221; the motor 221 is fixed to the door frame 110, and the connecting rod assembly 222 is transmission-connected to the cabinet door 120 at one end away from the motor 221. The motor 221 is installed on the top of the cabinet 100 and is connected to the monitoring unit 400 signal, and is used to open and close according to the signal of the monitoring unit 400, so as to control the connecting rod assembly 222 to pull the cabinet door 120 until the cabinet door 120 is closed, and the cabinet door 120 contacts the switch 210, triggering the switch 210, and the switch 210 gives the monitoring unit 400 a signal that it is closed in place, and the monitoring unit 400 controls the motor 221 to close. The door closing drive mechanism 220 can realize the automatic closing of the cabinet door 120 without manual closing. In the case of high temperature, power outage and fire, the cabinet opens the door to realize heat dissipation and fire protection linkage. When the fire protection is over, the monitoring unit 400 receives a signal to automatically drive the motor 221 to drive the connecting rod assembly 222 to realize automatic door closing operation. Timely closing of the cabinet door 120 helps the micro-module to resume normal working state as soon as possible, thereby improving the overall experience of the micro-module in the computer room.

[0064] In some embodiments, the connecting rod assembly 222 includes a first connecting rod 222a, a second connecting rod 222b and a third connecting rod 222c; the first end of the first connecting rod 222a is fixed to the output shaft of the motor 221, and the second end is hinged to the first end of the second connecting rod 222b; the first end of the third connecting rod 222c is hinged to the second end of the second connecting rod 222b, and the second end is hinged to the cabinet door 120, and the extension direction of the third connecting rod 222c is perpendicular to the output shaft of the motor 221.

[0065] One possible way to achieve this is as follows: Figure 8 As shown, the connecting rod assembly 222 includes a first connecting rod 222a, a second connecting rod 222b and a third connecting rod 222c which are sequentially connected in a transmission manner. The first connecting rod 222a is connected to the output shaft of the motor 221, and the third connecting rod 222c is hinged to the top surface of the cabinet door 120. Since the motor 221 is installed on the top surface of the cabinet body 100, and the output shaft of the motor 221 is perpendicular to the top surface of the cabinet body 100, in order to balance the height difference between the motor 221 and the cabinet door 120 in the longitudinal direction, the first connecting rod 222a includes a first section, a second section and a third section. The first section, the second section and the third section are connected to form a "Z"-shaped structure, as shown in FIG. Figure 8 As shown. Exemplarily, the extension direction of the first section is perpendicular to the axial direction of the output shaft of the motor 221, the extension direction of the second section is parallel to the axial direction of the output shaft of the motor 221, and the extension direction of the third section is parallel to the extension direction of the first section. The extension direction of the second connecting rod 222b and the extension direction of the third connecting rod 222c are both perpendicular to the axial direction of the output shaft of the motor 221.

[0066] One possible way to achieve this is Figure 9-12 The process of the motor 221 driving the connecting rod assembly 222 to drive the cabinet door 120 to move until the cabinet door 120 is closed is shown. The monitoring unit 400 sends a DO signal to the main board of the motor 221, and the motor 221 rotates 90° clockwise, and the cabinet door 120 is closed. The monitoring unit 400 detects the door closing signal through the micro switch installed on the door frame 110, and then transmits the door closing signal to the main board of the motor 221. The motor 221 starts to move and rotates 90° counterclockwise to reset, so as to avoid the connecting rod assembly 222 from tightening the cabinet door 120 all the time, thereby ensuring that the door can be opened normally next time. This process is completely an autonomous behavior of the cabinet system, without external forces intervening.

[0067] In some embodiments, the door closing drive mechanism 220 is used to close the cabinet door 120 when the cabinet door 120 is open, and is also used to open the cabinet door 120 when the cabinet door 120 is closed, that is, the door closing drive mechanism 220 can also be reused as a door opening drive mechanism. Specifically, the door closing drive mechanism 220 includes an electric telescopic rod 223, which is fixed to the door frame 110, and the output end of the electric telescopic rod 223 is hinged to the cabinet door 120.

[0068] One possible way to achieve this is Fig.13 and Fig.14 The process of the electric telescopic rod 223 driving the cabinet door 120 to move until the cabinet door 120 is closed is shown. The monitoring unit 400 sends a DO signal to the main board of the electric telescopic rod 223, the electric telescopic rod 223 retracts the push rod, the cabinet door 120 is closed, and the monitoring unit 400 detects the door closing signal through the micro switch 210 installed on the door frame 110, and then transmits the door closing signal to the main board of the electric telescopic rod 223, and the electric telescopic rod 223 stops moving. This process is completely an autonomous behavior of the cabinet system, without the intervention of external forces. For example, the electric telescopic rod 223 can be an electric push rod.

[0069] In one possible implementation, the electric push rod is installed on the top surface of the cabinet 100, and the push rod of the electric push rod is parallel to the top surface of the cabinet 100. In order to balance the height difference between the electric push rod and the cabinet door 120 in the longitudinal direction, a hinge column can be added to the top surface of the cabinet door 120, or an L-shaped structure can be added to the push rod of the electric push rod, such as Fig.15 As shown, the output end C of the push rod is hinged to the cabinet door 120.

[0070] In some embodiments, in order to facilitate operation and maintenance personnel to open and close the cabinet door 120, the cabinet also includes a control screen 600, and the control screen 600 is signal-connected to the monitoring unit 400 to facilitate manual interaction.

[0071] Reference Fig.16 The cabinet provided by the embodiment of the utility model has an autonomous intelligent control mode, a human intelligent control mode and a robot intelligent control mode. Among them:

[0072] In the autonomous intelligent control mode, when the air conditioner cannot operate normally, the temperature inside the micromodule rises. When the temperature reaches the set high temperature upper limit, the cabinet has a high temperature alarm, and the monitoring unit 400 outputs a DO signal to the door opening controller 510, disconnects the connection circuit of the electromagnet 521 through the relay 511, and the electromagnet 521 is powered off, the suction disappears, and the cabinet door 120 is opened under the push of the push rod of the pop-up opener 530. At this time, the heat in the cabinet can be dissipated. When the air conditioner resumes normal operation, the temperature inside the module gradually decreases, the high temperature alarm is lifted, and the monitoring unit 400 sends a DO signal to the motor 221 mainboard. The motor 221 rotates 90° clockwise, and the electromagnet 521 closes the door. The monitoring unit 400 detects the door closing signal through the micro switch installed on the door frame 110, and then transmits the door closing signal to the motor 221 mainboard. The motor 221 starts to move and rotates 90° counterclockwise to reset, so as to avoid the pull rod from tightening the cabinet door 120 all the time, thereby ensuring that the door can be opened normally next time. This process is completely an autonomous behavior of the cabinet system without external force intervention.

[0073] In the artificial intelligent control mode, the cabinet senses the fire signal and automatically pops open; when the fire is over, the operation and maintenance personnel directly issue a door closing command to the monitoring unit 400 through the control panel 600. First, the infrared probe on the door frame 110 will first detect whether there are people in the door closing range. If it is detected that there are no people in the door closing range, the monitoring unit 400 will give an action signal to the motor 221 mainboard, and the motor 221 will rotate 90° clockwise, and the electromagnet 521 will close the cabinet door 120. The monitoring unit 400 detects the door closing signal through the micro switch 210 installed on the door frame 110, and then transmits the door closing signal to the motor 221 mainboard. The motor 221 receives the door closing signal and rotates 90° counterclockwise to reset. When the cabinet door 120 is opened normally, the operation and maintenance personnel directly send a door opening command to the monitoring unit 400 through the control screen 600. When the monitoring unit 400 receives the door opening command, the infrared probe outside the door first detects whether there are people within the door opening range to prevent the operation and maintenance personnel from colliding with the door opening process. If it is detected that there are no people within the door closing range, the monitoring module outputs a DO signal to the door opening controller 510. The door opening controller 510 disconnects the connection circuit of the electromagnet 521 through the relay 511. The electromagnet 521 is powered off, the suction disappears, and the cabinet door 120 is opened under the thrust of the pop-up device 530.

[0074] In the robot intelligent control mode, when the intelligent inspection robot reaches the cabinet inspection position and cannot accurately judge the operating status of the server in the cabinet outside the cabinet, the inspection robot sends a wireless signal to the monitoring unit 400. The monitoring unit 400 receives the door opening command. First, the infrared probe outside the door detects whether the inspection robot is within the door opening range to prevent the robot from being damaged during the door opening process. If it is detected that the inspection robot is not within the door opening range, the monitoring module outputs a DO signal to the door opening controller 510. The door opening controller 510 disconnects the electromagnet 521 connection circuit through the relay 511, and the electromagnet 521 is powered off, the suction disappears, and the cabinet door 120 is opened under the push rod thrust of the pop-up device 530. Then the camera and detection probe of the inspection robot enter the cabinet for detection. After the inspection robot is finished, it sends a door closing command to the monitoring unit 400. First, the infrared probe on the cabinet door 120 will first detect whether the inspection robot is within the preset door closing range to prevent the inspection robot from being squeezed during the door closing process. If it is detected that the inspection robot is not within the preset range of closing the door, the monitoring unit 400 sends an action signal to the main board of the motor 221, the motor 221 rotates 90° clockwise, the electromagnet 521 closes the door, and the motor 221 receives the door closing signal and rotates 90° counterclockwise to reset.
