[0034] Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, which include various details of the embodiments of the present disclosure to help the understanding of the present disclosure. These should be considered in the context of the overall description and should not be considered limiting in any way. Thus, it will be apparent to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Also, for the sake of brevity and clarity, descriptions of well-known functions and constructions are omitted from the following description.

[0035] Figure 1a is a flowchart of an information acquisition method according to an embodiment of the present disclosure, which can be applied to the case of acquiring cloud computing unit state information through optical communication. The information acquisition method in the present embodiment can be applied to a target cloud computing unit. The target cloud computing unit is a cloud computing unit adjacent to the cloud computing unit to be detected and in a successful startup state. For example, the target cloud computing unit is a cloud computing unit located in front of the cloud computing unit to be detected and in a successful startup state.

[0036] The information acquisition method related in the embodiment can be executed by an information acquisition device, which can be implemented in software and / or hardware and specifically configured in an electronic device with certain data operation capability, which can be a client device or a server device. The client device can be a mobile phone, a tablet computer, a vehicle terminal, a desktop computer, etc. The server can be a cloud server, a distributed system server, or a server combined with a blockchain, etc. Specifically, refer to Figure 1a The method specifically includes the following steps:

[0037] S110, acquiring detection information for a to-be-detected cloud computing unit; the detection information includes relative position information between the to-be-detected cloud computing unit and a target cloud computing unit, and a detection instruction for the to-be-detected cloud computing unit.

[0038] The architecture of the cloud computing system is shown in Figure 1b As shown in the figure, a plurality of cloud computing units are deployed in the middle of the cloud computing server case, and the cloud computing units can be connected through a network or optical communication. The cloud computing platform can be connected with each cloud computing unit in the server case through the network, so as to obtain the working state of each cloud computing unit. Under the condition of normal operation, the cloud computing unit will send a heartbeat packet to the cloud computing platform according to the pre-set time period (for example, 15 seconds as a period). The cloud computing platform can determine whether each cloud computing unit is in a normal operation state according to the sending condition of the heartbeat packet.

[0039] The to-be-detected cloud computing unit is a cloud computing unit in the server case that needs to be detected. For example, the to-be-detected cloud computing unit is a cloud computing unit that does not send a heartbeat packet to the cloud computing platform for more than a set time threshold. The target cloud computing unit is used to detect the working state of the to-be-detected cloud computing unit, and the target cloud computing unit is a cloud computing unit adjacent to the to-be-detected cloud computing unit and in a normal operation state. For example, the target cloud computing unit is a cloud computing unit located in front of the to-be-detected cloud computing unit and in a normal operation state (sending a heartbeat packet to the cloud computing platform according to the set time period).

[0040] The detection information includes the relative position information between the to-be-detected cloud computing unit and the target cloud computing unit, and the detection instruction for the to-be-detected cloud computing unit. Specifically, the detection information is sent by the cloud computing platform to the target cloud computing unit, which is used to instruct the target cloud computing unit to detect the working state of the to-be-detected cloud computing unit. For example, the detection information includes that the to-be-detected cloud computing unit is located behind the target cloud computing unit, and a detection instruction for detecting the CPU (Central Processing Unit) temperature of the to-be-detected cloud computing unit.

[0041] The target cloud computing unit first receives the detection information sent by the cloud computing platform for the to-be-detected cloud computing unit, extracts the relative position information between the to-be-detected cloud computing unit and the target cloud computing unit and the detection instruction for the to-be-detected cloud computing unit contained in the detection information, so as to select the optical signal transmitter adjacent to the to-be-detected cloud computing unit according to the relative position information contained in the detection information, and send the detection instruction to the to-be-detected cloud computing unit, thereby obtaining the working state of the to-be-detected cloud computing unit.

[0042] In a specific example, the target cloud computing unit receives the detection information sent by the cloud computing platform through the network for the to-be-detected cloud computing unit, and extracts in the detection information that the to-be-detected cloud computing unit is located behind the target cloud computing unit, and the detection instruction for the to-be-detected cloud computing unit is to change the IP address of the to-be-detected cloud computing unit.

[0043] S120, receiving the optical signal emitted by the to-be-detected cloud computing unit through the target optical signal receiver associated with the relative position information.

[0044] The cloud computing units in the cloud computing server chassis are each installed with an optical signal receiver and an optical signal transmitter. Specifically, the optical signal transmitter and the optical signal receiver can be installed on the outer surface of each cloud computing unit according to the ordering mode of the cloud computing units in the cloud computing server, and can be directly connected to the main control chip inside the cloud computing unit, so that the main control chip of the cloud computing unit controls the optical signal transmitter and the optical signal receiver to perform optical communication with the adjacent cloud computing unit. The optical signal transmitter and the optical signal receiver can use infrared or visible light to realize optical communication, for example, the optical signal transmitter and the optical signal receiver can be a transmitting LED and a receiving LED. The specific modulation mode of the transmitting LED and the receiving LED can be Morse code or a custom binary format, for example, the transmitting LED is lit, and the adjacent receiving LED receives a signal of 1 (high level signal), and vice versa, the adjacent receiving LED receives a signal of 0 (low level signal). Each cloud computing unit in the cloud computing server chassis performs optical communication at a fixed baud rate.

[0045] For example, in the server chassis, each cloud computing unit is installed on a vertical plane, and the upper, lower, left and right of the cloud computing unit are adjacent to other cloud computing units, at this time, a pair of optical signal transmitter and optical signal receiver can be installed on the upper and lower surfaces of the cloud computing unit. For another example, in the server chassis, the cloud computing units are installed in a 3D form, that is, the upper, lower, left, right, front and back of the cloud computing units are adjacent to other cloud computing units, at this time, the installation mode of the optical signal transmitter and the optical signal receiver is as follows Figure 1cAs shown, a pair of optical signal transmitters and optical signal receivers can be installed on each of the six surfaces of the cloud computing unit, to realize optical communication between the cloud computing units.

[0046] In the embodiments of the present disclosure, after receiving the detection information of the to-be-detected cloud computing unit, the target cloud computing unit determines the optical signal receiver on the surface adjacent to the to-be-detected cloud computing unit as the target optical signal receiver according to the relative position information between the to-be-detected cloud computing unit and the target cloud computing unit in the detection information. Further, the target optical signal receiver is used to continuously receive the optical signal emitted by the to-be-detected cloud computing unit, to obtain the working state of the to-be-detected cloud computing unit.

[0047] In a specific example, the target cloud computing unit reads that the to-be-detected cloud computing unit is located behind the target cloud computing unit, and then determines the optical signal receiver on the rear surface as the target optical signal receiver, and further controls the optical signal receiver on the rear surface to continuously receive the optical signal emitted by the to-be-detected cloud computing unit, to determine the working state of the to-be-detected cloud computing unit.

[0048] S130, determining the working state of the to-be-detected cloud computing unit according to the received optical signal.

[0049] For ease of understanding, first, the case that each cloud computing unit controls the optical signal transmitter to emit optical signal in the starting process in the cloud computing server case is described as follows:

[0050] First, the cloud computing unit responds to the power-on operation of the administrator, and controls the optical signal transmitter on each surface to continuously emit a high-level signal. Further, the cloud computing unit controls the internal bootloader to perform a hardware self-checking operation, and when a hardware fault is detected, controls the optical signal transmitter on each surface to cyclically emit an error code matched with the hardware fault. The hardware fault can include a cloud computing unit network interface fault or a cloud computing unit storage chip fault, etc. In the case of no hardware fault, the operation system of the cloud computing unit is started. When an operation system starting fault occurs in the operation system starting process, the optical signal transmitter is controlled to cyclically emit an error code matched with the operation system starting fault. After the operation system is successfully started, the optical signal transmitter on each surface can be controlled to be turned off.

[0051] After the target optical signal receiver continuously receives the optical signal for a duration of T1, the working state of the cloud computing unit to be detected can be determined according to the received optical signal. Based on the control logic of the optical signal transmitter, specifically, when the optical signal transmitted by the cloud computing unit to be detected is a continuous low-level signal, it is determined that the cloud computing unit to be detected is in a successful startup state; when the optical signal transmitted by the cloud computing unit to be detected contains a high level, it can be determined that the cloud computing unit to be detected is not successfully started. For example, the duration T1 can be 8 times the duration of two adjacent bits in the optical communication baud rate.

[0052] Taking the self-defined binary as an example in the optical communication modulation mode, the optical signal transmitter is turned on, and the signal received by the adjacent optical signal receiver is 1, and vice versa, the signal received by the adjacent optical signal receiver is 0. If the optical signal received by the target optical signal receiver is all 0 within the duration T1, it is determined that the working state of the cloud computing unit to be detected is a successful startup; if the optical signal received by the target optical signal receiver is not all 0 within the duration T1, it can be determined that the cloud computing unit to be detected is not successfully started, specifically, the cloud computing unit to be detected can be in a startup state or send an error code state.

[0053] S140, according to the working state of the cloud computing unit to be detected, a detection instruction is sent to the cloud computing unit to be detected through the target optical signal transmitter associated with the opposite position information.

[0054] The detection instruction can be an instruction to obtain the state information of the cloud computing unit to be detected, or an instruction to control the cloud computing unit to be detected to set the state information. For example, the instruction to obtain the state information of the cloud computing unit to be detected includes obtaining the CPU temperature of the cloud computing unit to be detected, or obtaining the length of a specific file in the cloud computing unit to be detected. The instruction to control the cloud computing unit to be detected to set the state information is to control the cloud computing unit to be detected to reset the IP address.

[0055] In the embodiment of the disclosure, after determining the working state of the cloud computing unit to be detected, a detection instruction can be sent to the cloud computing unit to be detected through the target optical signal transmitter associated with the opposite position information according to the working state of the cloud computing unit to be detected. Specifically, when it is determined that the cloud computing unit to be detected is in a successful startup state, the optical signal transmitter on the adjacent surface of the cloud computing unit to be detected is determined as the target optical signal transmitter. Then, the detection instruction is sent to the cloud computing unit to be detected through the target optical signal transmitter.

[0056] In one specific example, after determining that the cloud computing unit to be detected is in a successful startup state, a control instruction to change the IP address is sent to the cloud computing unit to be detected through the optical signal transmitter on the adjacent surface of the cloud computing unit to be detected.

[0057] The technical scheme of the embodiment of the present disclosure first acquires detection information for the to-be-detected cloud computing unit, then receives the optical signal emitted by the to-be-detected cloud computing unit through the target optical signal receiver associated with the relative position information, further determines the working state of the to-be-detected cloud computing unit according to the received optical signal, and finally sends a detection instruction to the to-be-detected cloud computing unit through the target optical signal transmitter associated with the relative position information according to the working state of the to-be-detected cloud computing unit, so that the target cloud computing unit acquires the state information of the to-be-detected cloud computing unit adjacent thereto in an optical communication manner. Compared with the technical scheme of setting a dedicated fault positioning chip in a server case, the fault positioning can be realized at a low cost.

[0058] Figure 2 is a schematic diagram of an information acquisition method in the embodiment of the present disclosure, which is further refined on the basis of the above embodiment and provides specific steps of determining the working state of the to-be-detected cloud computing unit according to the received optical signal. The following will be described in combination with Figure 2 The information acquisition method provided in the embodiment of the present disclosure is described, which includes the following:

[0059] S210, acquire detection information for the to-be-detected cloud computing unit; the detection information includes relative position information between the to-be-detected cloud computing unit and the target cloud computing unit, and a detection instruction for the to-be-detected cloud computing unit.

[0060] Optionally, the target cloud computing unit is selected from candidate cloud computing units adjacent to the to-be-detected cloud computing unit.

[0061] In the optional embodiment, the target cloud computing unit is selected from candidate cloud computing units adjacent to the to-be-detected cloud computing unit. Since visible light or infrared is used to realize optical communication between cloud computing units in the embodiment, only adjacent cloud computing units can realize such optical communication. Therefore, when detecting the state of the to-be-detected cloud computing unit, a target cloud computing unit needs to be selected from a plurality of cloud computing units adjacent to the to-be-detected cloud computing unit, and then the target cloud computing unit is controlled to detect the state of the to-be-detected cloud computing unit through the above optical communication manner. Compared with the detection manner of specially assigning an administrator to detect faults or installing a dedicated detection chip, the detection cost of faults is reduced.

[0062] Exemplarily, the candidate cloud computing units adjacent to the cloud computing unit to be detected include: a candidate cloud computing unit A located in front of the cloud computing unit to be detected, a candidate cloud computing unit B located behind the cloud computing unit to be detected, a candidate cloud computing unit C located on the left of the cloud computing unit to be detected, a candidate cloud computing unit D located on the right of the cloud computing unit to be detected, a candidate cloud computing unit E located above the cloud computing unit to be detected, and a candidate cloud computing unit F located below the cloud computing unit to be detected. One of the above six candidate cloud computing units can be selected as a target cloud computing unit to detect the state of the cloud computing unit to be detected.

[0063] Optionally, the target cloud computing unit is selected from the candidate cloud computing units in the successful start state.

[0064] In the optional embodiment, since only the cloud computing unit in the successful start state can successfully obtain the detection information issued by the cloud computing platform, the target cloud computing unit is further selected from the candidate cloud computing units in the successful start state.

[0065] Exemplarily, the cloud computing platform can read the time stamps of the heartbeat packets sent by each candidate cloud computing unit respectively, and when the time distance from the last time of sending the heartbeat packet to the current time is less than a set time threshold, it is determined that the candidate cloud computing unit is in the successful start state. Finally, one of the candidate cloud computing units in the successful start state can be randomly selected as the target cloud computing unit, which reduces the cost of fault detection, and at the same time, by selecting the cloud computing unit in the successful start state as the target detection unit, the reliability of fault detection is ensured.

[0066] S220, receiving the optical signal emitted by the cloud computing unit to be detected through the target optical signal receiver associated with the opposite direction information.

[0067] S230, in the case that the first optical signal received in the first time interval is all low-level signal, determining that the cloud computing unit to be detected is in the successful start state.

[0068] In the embodiment of the present disclosure, the target cloud computing unit analyzes the first optical signal received by the target optical signal receiver in the first time interval, and if the first optical signal is all low-level signal, it is determined that the cloud computing unit to be detected is in the successful start state. The first time interval can be set to 8 times the length of the adjacent two bits in the optical communication baud rate.

[0069] S240, in the case that the cloud computing unit to be detected is in the successful start state, sending a detection instruction to the cloud computing unit to be detected through the target optical signal transmitter associated with the opposite direction information.

[0070] In a case where it is determined that the cloud computing unit to be detected is in a successful startup state, a detection instruction is sent to the cloud computing unit to be detected through the target optical signal transmitter associated with the opposite direction information, so as to obtain the state information of the cloud computing unit to be detected, or instruct the cloud computing unit to be detected to perform a software setting operation. The detection instruction can be the CPU temperature or file length of the cloud computing unit to be detected, which can assist in determining the fault point of the cloud computing unit to be detected. The detection instruction can also be a software setting of the cloud computing unit to be detected, for example, modifying the IP address. The software repair of the cloud computing unit to be detected can be realized through optical communication, without the need for staff to take out the cloud computing unit to be detected for software repair, thereby reducing the cost of software repair.

[0071] In a case where it is determined that the cloud computing unit to be detected is not in a successful startup state according to the first optical signal received in the first time interval, the working state of the cloud computing unit to be detected is determined according to the second optical signal received in the second time interval.

[0072] In the embodiment of the present disclosure, if the first optical signal received in the first time interval is not all low-level signals, it is determined that the cloud computing unit to be detected is not in a successful startup state. In a case where the cloud computing unit to be detected is not in a successful startup state, the second optical signal sent by the cloud computing unit to be detected is continuously received through the target optical signal receiver in the second time interval, and the working state of the cloud computing unit to be detected is determined by analyzing the second optical signal. The second time interval is after the first time interval, and specifically, the start time of the second time interval is the end time of the first time interval. The target cloud computing unit locates the specific fault of the cloud computing unit to be detected by receiving the optical signal, reduces the cost of fault positioning, and improves the efficiency of fault positioning.

[0073] It is worth noting that S240 and S250 are executed according to the working state of the cloud computing unit to be detected.

[0074] For example, if the second optical signal received in the second time interval is all high-level signals, it can be determined that the cloud computing unit to be detected is in a startup state; if the second optical signal contains both high-level signals and low-level signals, it can be determined that the cloud computing unit to be detected is in a fault state, and specific fault positioning needs to be further analyzed to obtain the second optical signal.

[0075] Optionally, determining the working state of the cloud computing unit to be detected according to the second optical signal received in the second time interval comprises:

[0076] In a case where the second optical signals received in the second time interval are all high-level signals, it is determined that the cloud computing unit to be detected is in a starting state;

[0077] In a case where the second optical signals received in the second time interval include high-level signals and low-level signals, an error code of the cloud computing unit to be detected is determined according to the high-level signals and the low-level signals in the second optical signals; the error code is used to represent a working state of the cloud computing unit to be detected.

[0078] In the optional embodiment, a manner of determining a working state of the cloud computing unit to be detected according to the second optical signals received in the second time interval is provided: since the cloud computing unit controls the optical signal transmitter to continuously emit high-level signals in the starting process, after successful starting, the optical signal transmitter is turned off. If the second optical signals received in the second time interval are all high-level signals, it is determined that the cloud computing unit to be detected is in a starting state; if the second optical signals received in the second time interval include high-level signals and low-level signals, it is necessary to further analyze error codes corresponding to the high-level signals and the low-level signals in the second optical signals, and determine specific fault information of the cloud computing unit to be detected according to the error codes, so as to realize positioning of the fault of the cloud computing unit to be detected through the optical communication manner, improve the fault positioning efficiency, and reduce the fault positioning cost. The error code is used to represent the working state of the cloud computing unit to be detected, for example, an operating system starting fault, a network interface fault, or a storage chip fault, etc., which all correspond to different error codes.

[0079] The technical solution of the embodiment of the present disclosure is that the target cloud computing unit obtains detection information of the cloud computing unit to be detected, and then receives optical signals emitted by the cloud computing unit to be detected through the target optical signal receiver associated with the relative position information. In a case where the first optical signals received in the first time interval are all low-level signals, it is determined that the cloud computing unit to be detected is in a successful starting state, and a detection instruction is sent to the cloud computing unit to be detected through the target optical signal transmitter associated with the relative position information. In a case where it is determined that the cloud computing unit to be detected is not in the successful starting state according to the first optical signals received in the first time interval, a working state of the cloud computing unit to be detected is determined according to the second optical signals received in the second time interval, state information of the cloud computing unit to be detected is obtained through the optical communication manner, the fault positioning efficiency is improved, and the fault positioning cost is reduced.

[0080] Figure 3 is a schematic diagram of an information acquisition method in the embodiment of the present disclosure, which is further refined on the basis of the above-mentioned embodiment, and provides specific steps after the detection instruction is sent to the cloud computing unit to be detected. The following will be described in combination with Figure 3 An information acquisition method provided by the embodiment of the present disclosure is described, which includes the following:

[0081] S310, acquire detection information for the to-be-detected cloud computing unit; the detection information comprises relative position information between the to-be-detected cloud computing unit and the target cloud computing unit, and a detection instruction for the to-be-detected cloud computing unit.

[0082] S320, receive, by a target optical signal receiver associated with the relative position information, an optical signal emitted by the to-be-detected cloud computing unit.

[0083] S330, determine, according to the received optical signal, a working state in which the to-be-detected cloud computing unit is located.

[0084] S340, according to the working state in which the to-be-detected cloud computing unit is located, send, by a target optical signal transmitter associated with the relative position information, the detection instruction to the to-be-detected cloud computing unit.

[0085] S350, acquire, by the target optical signal receiver associated with the relative position information, a detection result obtained by the to-be-detected cloud computing unit by executing the detection instruction.

[0086] After sending the detection instruction to the to-be-detected cloud computing unit, acquire, by the target optical signal receiver associated with the relative position information, a detection result obtained by the to-be-detected cloud computing unit by executing the detection instruction.

[0087] In one specific example, the to-be-detected cloud computing unit is located to the left of the target optical signal unit, and then the target optical signal unit receives, by an optical signal receiver located on the left surface, the optical signal sent by the to-be-detected cloud computing unit after sending the detection instruction, so as to acquire the detection instruction execution result contained in the optical signal, thereby realizing the acquisition of the state information of the to-be-detected cloud computing unit in the case of failure of the to-be-detected cloud computing unit through optical communication, or the software repair through optical communication. For example, the detection instruction execution result can be whether the CPU temperature in the to-be-detected cloud computing unit, the length of a specific file in the to-be-detected cloud computing unit, or a software modification instruction (for example, an IP address modification instruction) is successfully executed.

[0088] Optionally, after sending the detection instruction to the to-be-detected cloud computing unit, the method further comprises:

[0089] If the detection result fed back by the to-be-detected cloud computing unit is not received by the target optical signal receiver within the waiting time interval, it is determined that the to-be-detected cloud computing unit is in a power-off state, and after determining the specific failure cause, the failure cause can be fed back to the cloud computing platform, so that the cloud computing platform displays the failure cause, and the administrator does not need to detect the failure in the case, thereby reducing the failure detection cost.

[0090] In the optional embodiment, after sending the detection instruction to the cloud computing unit to be detected, the target optical signal receiver associated with the opposite direction information is used to continuously receive the optical signal emitted by the cloud computing unit to be detected, so as to extract the detection instruction execution result contained in the optical signal. If the detection result fed back by the cloud computing unit to be detected is not received within the preset waiting time interval, it can be determined that the cloud computing unit to be detected is in a power-off state, and at this time, the target cloud computing unit can directly feed back the information of the power-off of the cloud computing unit to be detected to the cloud computing platform, so as to realize the positioning of the specific fault of the cloud computing unit to be detected through the optical communication mode.

[0091] The technical scheme of the embodiment of the present disclosure obtains the detection information of the cloud computing unit to be detected, and then receives the optical signal emitted by the cloud computing unit to be detected through the target optical signal receiver associated with the opposite direction information, and determines the working state of the cloud computing unit to be detected according to the received optical signal. Further, according to the working state of the cloud computing unit to be detected, the detection instruction is sent to the cloud computing unit to be detected through the target optical signal transmitter associated with the opposite direction information, and finally the detection result obtained by the cloud computing unit to be detected by executing the detection instruction is obtained through the target optical signal receiver associated with the opposite direction information, so as to realize the positioning of the specific fault of the cloud computing unit to be detected through the optical communication mode.

[0092] In order for those skilled in the art to better understand the information acquisition method involved in the present disclosure, Figure 4a According to the embodiment of the present disclosure, a schematic diagram of an information acquisition method is provided, mainly including the following:

[0093] S410, the cloud computing platform determines the cloud computing unit to be detected according to the time stamp of the heartbeat packet sent by the cloud computing unit.

[0094] When the cloud computing unit is installed into the cloud computing server case, the position of the cloud computing unit in the case and the IP address of the cloud computing unit are stored into the cloud computing platform. The cloud computing platform can access a certain cloud computing platform through the network. In the case of cloud computing unit failure, the adjacent cloud computing platform can also be accessed through the network, so that the adjacent cloud computing platform obtains the specific fault information of the cloud computing unit through the optical communication mode.

[0095] After the operating system of the cloud computing unit is successfully started, the cloud computing unit will send a heartbeat packet to the cloud computing platform at a set time period. The processing flow of the cloud computing platform is as follows Figure 4bAs shown, the cloud computing platform receives the heartbeat packet and stores the timestamp of receiving the heartbeat packet to determine whether the cloud computing unit is in normal operation according to the timestamp. When the cloud computing unit does not send a heartbeat packet to the cloud computing platform for more than a set time threshold, it indicates that the cloud computing unit may be malfunctioning, and the cloud computing unit can be determined as a to-be-detected cloud computing unit. According to the above manner, at least one to-be-detected cloud computing unit is determined in the cloud computing server case to form a to-be-detected cloud computing unit list L1.

[0096] S420, the cloud computing platform determines a target cloud computing unit in the cloud computing unit adjacent to the to-be-detected cloud computing unit.

[0097] For each to-be-detected cloud computing unit in the to-be-detected cloud computing unit list L1, the cloud computing platform can determine at least one candidate cloud computing unit adjacent to the to-be-detected cloud computing unit according to the arrangement order of the cloud computing units in the cloud computing server case to form a candidate cloud computing unit list L2. Further, at least one candidate cloud computing unit in a normal operation state can be determined according to the timestamp of the candidate cloud computing unit sending the heartbeat packet, and finally, one of the candidate cloud computing units in the normal operation state is randomly selected as the target cloud computing unit.

[0098] S430, the cloud computing platform sends detection information for the to-be-detected cloud computing unit to the target cloud computing unit; the detection information includes relative position information between the to-be-detected cloud computing unit and the target cloud computing unit, and a detection instruction for the to-be-detected cloud computing unit.

[0099] After determining the target cloud computing unit, the cloud computing platform sends detection information for the to-be-detected cloud computing unit to the target cloud computing unit to instruct the target cloud computing unit to send a detection instruction to the to-be-detected cloud computing unit according to the relative position information between the to-be-detected cloud computing unit and the target cloud computing unit in the detection information.

[0100] S440, the target cloud computing unit obtains the detection information for the to-be-detected cloud computing unit, and receives the optical signal emitted by the to-be-detected cloud computing unit through the target optical signal receiver associated with the relative position information.

[0101] The processing flow of the target cloud computing unit is as shown in Figure 4c As shown, the target cloud computing unit will turn off the optical signal transmitter after successfully starting, and then send a heartbeat packet to the cloud computing platform at a set time period. When the cloud computing platform receives the receiving success information fed back by the cloud computing platform for the heartbeat packet, it is determined that the network is connected with the cloud computing platform.

[0102] Further, the target cloud computing unit receives detection information sent by the cloud computing platform for the to-be-detected cloud computing unit within a set time period. If the detection information is not received within the set time period, the operation of sending the heartbeat packet is continuously performed. If the detection information is received within the set time period, the relative position information between the to-be-detected cloud computing unit and the target cloud computing unit and the detection instruction for the to-be-detected cloud computing unit in the detection information are extracted.

[0103] S450, the target cloud computing unit determines the working state of the to-be-detected cloud computing unit according to the received optical signal.

[0104] After obtaining the detection information, the target cloud computing unit continuously receives the optical signal T1 of the to-be-detected cloud computing unit through the optical signal receiver. If the optical signals received within the T1 time period are all low-level signals (i.e., the optical signals are all 0), it is determined that the to-be-detected cloud computing unit is in a successful startup state. Otherwise, it is determined that the to-be-detected cloud computing unit is in an unsuccessful startup state. The unsuccessful startup state includes a startup-in-progress state and a fault state. Specifically, when the optical signals received within the T1 time period are all high-level signals, it is determined that the to-be-detected cloud computing unit is in a startup-in-progress state. When the optical signals received within the T1 time period contain both high-level signals and low-level signals, an error code can be determined according to the received optical signals, and different error codes correspond to different types. The target cloud computing unit can send information that the to-be-detected cloud computing unit is in a startup-in-progress state to the cloud computing platform, or send an error code to the cloud computing platform.

[0105] S460, the target cloud computing unit sends a detection instruction to the to-be-detected cloud computing unit through the target optical signal transmitter associated with the relative position information according to the working state of the to-be-detected cloud computing unit.

[0106] When the target cloud computing unit determines that the to-be-detected cloud computing unit is in a successful startup state according to the optical signal sent by the to-be-detected cloud computing unit, the target cloud computing unit sends a detection instruction to the to-be-detected cloud computing unit through the target optical signal transmitter associated with the relative position, and continuously listens to the detection instruction execution result feedback by the to-be-detected cloud computing unit through the target optical signal receiver associated with the relative position.

[0107] S470, the to-be-detected cloud computing unit executes the detection instruction sent by the target cloud computing unit and feeds back the execution result of the detection instruction to the target cloud computing unit.

[0108] The cloud computing unit to be detected continuously monitors the optical signals transmitted by the adjacent cloud computing units through the optical signal receivers. If the detection instruction transmitted by the adjacent target cloud computing unit is received, the detection instruction is executed, and the instruction execution result is transmitted to the target cloud computing unit through the optical signal. If the detection instruction transmitted by the target cloud computing unit is not received, the cloud computing platform can continue to send the heartbeat packet. If the receiving success information fed back by the cloud computing platform for the heartbeat packet is received, the fault state can be exited. Otherwise, the detection instruction transmitted by the target cloud computing unit is continuously monitored.

[0109] S480, the target cloud computing unit uploads the execution result to the cloud computing platform.

[0110] After receiving the execution result of the detection instruction fed back by the cloud computing unit to be detected, the target cloud computing unit uploads the execution result to the cloud computing platform. If the target cloud computing unit does not receive the execution result fed back by the cloud computing unit to be detected after waiting for a set time length, the cloud computing platform can feed back information that the cloud computing unit to be detected is in a power-off state.

[0111] When the cloud computing platform receives that the cloud computing unit to be detected is in a starting state or a power-off state, the cloud computing platform can repeatedly send the detection information for the cloud computing unit to be detected to the target cloud computing unit for 3 times. If the received state information is still in the starting state or the power-off state, it is determined that the cloud computing unit to be detected has a starting fault or a power-off. Finally, the cloud computing platform can store the working state of the cloud computing unit to be detected to a database and display it, so that the management personnel can locate the fault of the cloud computing unit to be detected and repair it.

[0112] The technical scheme of the embodiment of the disclosure is that the target cloud computing unit obtains the detection information for the cloud computing unit to be detected, and then receives the optical signal emitted by the cloud computing unit to be detected through the target optical signal receiver associated with the opposite direction information. Further, according to the received optical signal, the working state of the cloud computing unit to be detected is determined, and finally according to the working state of the cloud computing unit to be detected, the detection instruction is sent to the cloud computing unit to be detected through the target optical signal transmitter associated with the opposite direction information, so that the target cloud computing unit obtains the state information of the adjacent cloud computing unit to be detected through the optical communication mode, and realizes the low-cost fault positioning.
