As shown in fig. 6, the infrared rays emitted from the emitting tube 1242 are transmitted through the light guide post 1233, emitted to the light shielding member 300 (in this embodiment, the hand of the operator can be used), reflected by the light shielding member 300, and transmitted to the receiving tube 1243 through the light guide post 1233. In fig. 6, infrared rays emitted from the emission tube 1242 are indicated by solid lines with arrows, and infrared rays reflected by the light-shielding member 300 are indicated by broken lines with arrows, where the arrows indicate the transmission directions of light. The internal structure of the hard disk assembly 123 can be simplified by transmitting and receiving infrared rays through one light guide post 1233.
Fig. 7 is a partial schematic diagram of a third computing device according to an embodiment of the present application. Referring to fig. 7, based on the embodiment shown in fig. 6, the number of the light guide posts 1233 is two, one light guide post 1233 is opposite to the emission tube 1242, and the other light guide post 1233 is opposite to the receiving tube 1243.
That is to say, the projection of one light guide post 1233 on the hard disk backboard 122 only needs to cover the projection of the transmitting tube 1242 on the hard disk backboard 122, and the projection of another light guide post 1233 on the hard disk backboard 122 only needs to cover the projection of the receiving tube 1243 on the hard disk backboard 122, so that the light guide post 1233 can be flexibly selected according to the specific sizes of the transmitting tube 1242 and the receiving tube 1243.
Fig. 8 is a partial schematic diagram of a fourth computing device provided in the embodiment of the present application. Referring to fig. 8, in addition to the embodiment shown in fig. 7, the hard disk assembly 123 further includes an LED indicator 1234, the LED indicator 1234 may be fixed on the hard disk support 1231, and the LED indicator 1234 is electrically connected to the hard disk 1232 through a third cable L3, and is electrically connected to the control assembly 121 sequentially via the hard disk 1232, the hard disk back plate 122, and the main board 125.
When the hard disk 1232 is not required to be hot plugged, the LED indicator 1234 is in an off state. After the control component 121 issues the hot plug command and disconnects the data transmission and the electrical connection between the hard disk 1232 in the hard disk component 123 and the motherboard 125, the control component 121 issues a hot plug completion signal and lights the LED indicator 1234 according to the hot plug completion signal. After seeing that the LED indicator 1234 lights up, the operator removes the corresponding hard disk assembly 123 from the hard disk back plate 122.
In other embodiments, the status of the LED indicator 1234 may also be reversed from the embodiments described above. Specifically, when the hard disk 1232 does not need to be hot plugged, the LED indicator 1234 may be turned on. After the data transmission and the electrical connection between the hard disk 1232 in the hard disk assembly 123 and the motherboard 125 are disconnected, the control assembly 121 sends a hot plug completion signal, the LED indicator 1234 is turned off according to the hot plug completion signal, and an operator removes the corresponding hard disk assembly 123 from the hard disk backplane 122 after seeing that the LED indicator 1234 is turned off.
In order to avoid the hot plug of the hard disk 1232 caused by the mistaken triggering of the ir-reflective sensor 1241 by the hand of the operator, the control component 121 is configured to recognize the hot plug signal after the receiving pipe 1243 receives the reflected infrared ray and continues to receive the reflected infrared ray for a set time.
A preset trigger time, called a set time, is preset in the control module 121, and the set time may be 3 to 5 seconds. After the control component 121 detects that the time of the reflected infrared ray received by the receiving tube 1243 exceeds the set time, the electrical signal sent by the receiving tube 1243 is recognized as a hot plug signal. Therefore, when the light guide column 1233 is accidentally shielded, the control assembly 121 malfunctions, so that the hard disk 1232 which does not need to be hot-plugged needs to be disconnected from the mainboard 125 in data transmission and electric connection.
In other embodiments, false triggering of the infrared-reflective sensor 1241 may also be prevented by the UID key 127 in the computing device 120. Fig. 9 is a schematic structural diagram of a computing device according to an embodiment of the present application. Referring to fig. 9, based on the embodiment shown in fig. 3, the computing device 120 further includes a UID key 127, the UID key 127 is disposed on the cabinet 126 of the computing device 120, and the UID key 127 is electrically connected to the control component 121; the UID key 127 is configured to send a hot plug start signal to the control component 121, the control component 121 is configured to send a detection instruction and start to detect that the receiving tube 1243 receives the reflected infrared ray after receiving the hot plug start signal, and the receiving tube 1243 is configured to generate a hot plug signal when receiving the reflected infrared ray.
Specifically, a plurality of computing devices 120 are generally disposed in the data center 100, in order to facilitate locating the computing devices 120 by an operator, a UID key 127 is generally disposed on the computing devices 120, the computing devices 120 further include a key pad 128, the UID key 127 is soldered on the key pad 128 and electrically connected to the key pad 128, the key pad 128 can be fixed on the front panel of the cabinet 126 by fasteners, and the key pad 128 is electrically connected to the main board 125 by a fourth cable L4. The UID is an abbreviation of unit identification light, i.e., a unit indication key.
Next, the usage of the UID key 127 will be briefly described. The rear panel of the cabinet 126 is provided with a UID lamp 1271, and the UID lamp 1271 is electrically connected to the main board 125 through a fifth cable L5, and thus electrically connected to the UID key 127 through the main board 125. The operator presses the UID key 127 on the front panel and the UID lamp 1271 on the back panel lights up to alert the operator to help the operator find the desired located computing device 120. In the embodiment shown in fig. 9, UID key 127 is also electrically connected to control component 121 through motherboard 125.
Fig. 10 is a schematic diagram illustrating a second process of performing hot plug on a hard disk assembly through a hot plug switch in a computing device according to an embodiment of the present application. It should be noted that, since the hard disk backplane 122 only functions as an electrical signal relay, the hard disk backplane 122 is omitted in fig. 10 and the subsequent similar views for clarity.
Referring to fig. 10, when one or more hard disks 1232 in the computing device 120 need to be unplugged, the UID key 127 is pressed by an operator, and after the UID key 127 sends a hot plug start signal to the control component 121, the control component 121 sends a detection instruction to start detecting whether the receiving pipe 1243 receives the reflected infrared ray. When an operator shields the hand from the light emitting side of the ir reflective sensor 1241, the receiving tube 1243 receives the reflected ir and forms a hot plug signal, and the hot plug signal is transmitted to the control component 121 through the motherboard 125. After receiving the hot plug signal, the control component 121 sends a hot plug instruction to the motherboard 125 according to the hot plug signal, the motherboard 125 stops data transmission between the hard disk component 123 and the motherboard 125 according to the hot plug instruction, disconnects the hard disk component 123 from the motherboard 125, and then pulls out the hard disk component 123 by an operator. Therein, the electrical connection and data transmission of the hard disk assembly 123 to the motherboard 125 are also shown in fig. 9 by bold dashed lines with double-headed arrows.
The emitter tube 1242 is always in a state of emitting infrared rays, and the receiver tube 1243 is always in a state of receiving reflected infrared rays. When the UID key 127 is pressed by an operator when hot plugging of the hard disk 1232 is required, the UID key 127 sends a hot plugging start signal to the control component 121, and the control component 121 starts to detect whether the receiving tube 1243 receives the reflected infrared ray.
The UID key 127 is used for sending a hot plug starting signal to trigger the control component 121 to send a detection instruction to start detecting whether the receiving tube 1243 receives the reflected infrared ray, so that misoperation of an operator can be effectively avoided. In addition, the UID key 127 sends out a hot plug start signal, so that the control component 121 can be triggered to start detecting whether the receiving pipe 1243 receives the reflected infrared ray only when the hard disk component 123 needs to be hot plugged, thereby saving resources of the control component 121.
Next, each component of the control unit 121 will be explained.

At this time, the operator shields the hand from the light-emitting side of the ir reflective sensor 1241, the receiving tube 1243 receives the reflected ir and forms a hot plug signal, and the hot plug signal is transmitted to the first programmable logic device 1211 through the motherboard 125. That is, the first programmable logic device 1211 in the control component 121 is configured to perform a process of identifying a hot plug signal and transmit the hot plug signal to the first controller 1212, so that the efficiency of processing signals by the first controller 1212 may be improved.
After receiving the hot plug signal, the first controller 1212 issues a hot plug command, thereby disconnecting the data transmission and the electrical connection between the hard disk 1232 in the hard disk assembly 123 and the motherboard 125.

In other embodiments, the hot plug signals sent by the ir-reflective sensors 1241 may be binary coded to control the hot plug of a greater number of hard disk assemblies 123 through a smaller number of ir-reflective sensors 1241, so that the number of ir-reflective sensors 1241 used may be reduced to further reduce the cost of the computing device 120. This scheme is specifically described below.
Fig. 14 is a schematic structural diagram of a computing device provided in an embodiment of the present application; fig. 15 is an enlarged view at a in fig. 14. Referring to fig. 14 and 15, the hot swap switch 124 includes at least two infrared reflective sensors 1241, where the at least two infrared reflective sensors 1241 are disposed side by side on the key board 128 and electrically connected to the control component 121 through the key board 128; the at least two infrared reflective sensors 1241 are used for generating hot plug signals; the control component 121 is configured to receive a hot plug signal, perform binary coding on the hot plug signal to form at least four encoded hot plug signals corresponding to the hard disk components 123 one to one, and issue a hot plug instruction to the motherboard 125 according to the encoded hot plug signals to disconnect data transmission and electrical connection between the hard disk components 123 and the motherboard 125.
Specifically, in this embodiment, the hot swap switch 124 may include two ir-reflective sensors 1241, or may include more than two ir-reflective sensors 1241, for example, three or four ir-reflective sensors 1241. In the embodiment shown in fig. 14 and 15, the hot swap switch is described by taking the example that the hot swap switch 124 includes three infrared reflective sensors 1241. The three ir-reflective sensors 1241 are soldered on the key sheet 128 side by side, and are electrically connected to the control unit 121 through a fourth cable L4 connected to the key sheet 128.
Fig. 16 is a sixth schematic view of a process of performing hot plug on a hard disk assembly through a hot plug switch in a computing device according to an embodiment of the present application. Referring to fig. 16, three ir-reflective sensors 1241 are electrically connected to the control module 121 through the motherboard 125. With continued reference to fig. 15 and 16, for convenience of description, the three ir-reflective sensors 1241 are referred to as a first ir-reflective sensor 1241a, a second ir-reflective sensor 1241b, and a third ir-reflective sensor 1241c, respectively.
Next, a process of the control unit 121 encoding the three ir reflective sensors 1241 will be described. With continued reference to fig. 16, three ir-reflective sensors 1241 each have an occluded state and an unoccluded state, wherein the occluded state is represented by a "1" in the binary code and the unoccluded state is represented by a "0" in the binary code.
When the first ir-reflective sensor 1241a, the second ir-reflective sensor 1241b and the third ir-reflective sensor 1241c are all in the non-blocking state "0", the control component 121 encodes the hot plug signal generated by the three ir-reflective sensors 1241 to "000", which is called as a coded hot plug signal, and the coded hot plug signal "000" may send a hot plug instruction to correspondingly trigger the hot plug of one hard disk component 123;
when the first ir-reflective sensor 1241a is in the shielding state "1", and both the second ir-reflective sensor 1241b and the third ir-reflective sensor 1241c are in the non-shielding state "0", the control component 121 encodes this state as "001" shown in fig. 16, and the encoded hot plug signal "001" may issue a hot plug command to correspondingly trigger hot plug of one hard disk component 123;
when the second ir-reflective sensor 1241b is in the shielding state "1", and both the first ir-reflective sensor 1241a and the third ir-reflective sensor 1241c are in the non-shielding state "0", the control component 121 encodes the hot plug signal generated by the three ir-reflective sensors 1241 to "010", and the encoded hot plug signal "010" may send a hot plug instruction to correspondingly trigger the hot plug of one hard disk component 123;
when the third ir-reflective sensor 1241c is in the non-shielded state "0", and both the first ir-reflective sensor 1241a and the second ir-reflective sensor 1241b are in the shielded state "1", the control component 121 encodes the hot plug signal generated by the three ir-reflective sensors 1241 to "011", and the encoded hot plug signal "011" may issue a hot plug instruction to correspondingly trigger the hot plug of one hard disk component 123;
by analogy, there may be four encoded hot plug signals "100", "101", "110" and "111" (for clarity, the four encoded hot plug signals are not shown in fig. 16), and the use of three ir-reflective sensors 1241 may correspondingly trigger the hot plug of eight hard disk assemblies 123, thereby reducing the number of ir-reflective sensors 1241.
As can be understood, in actual operation, when the first ir-reflective sensor 1241a, the second ir-reflective sensor 1241b and the third ir-reflective sensor 1241c are all in the non-blocking state "0", the encoded hot plug signal "000" is not available, and the control component 121 does not issue a hot plug instruction to the motherboard, that is, the three ir-reflective sensors 1241 may trigger hot plug of the seven hard disk components 123 correspondingly. The four infrared reflective sensors 1241 can be triggered correspondingly (2) 4 -1) hot plug of hard disk assembly 123, five ir-reflective sensors 1241 may be triggered (2) correspondingly 5 -1) hot-plugging of hard disk assembly 123, and so on.
