[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] The terms "first," "second," "third," and "fourth," etc., in the specification, claims, and drawings of this application are used to distinguish between different objects, not to describe a particular order. In addition, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0035] References herein to "embodiments" mean that a particular feature, result, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] First, the relevant technologies involved in this application are explained:

[0037] Refer to Figure 1, which is a schematic diagram of a control system provided in an embodiment of the present application. The control system shown in Figure 1 includes a central control host and a computing device, wherein the central control host is short-circuited with the power button of the computing device through a first connecting line, so that the central control host sends a control signal (such as a power-on signal, a power-off signal, a sleep signal, etc.) to the computing device through the first connecting line, and the central control host and the computing device are also connected through a second connecting line, so that the computing device sends a media signal (such as audio, image, video, etc.) to the central control host through the second connecting line. Among them, short-circuiting the first connecting line requires disassembling the computing device for wiring, which will destroy the original appearance of the computing device, and the method of disassembling the wiring is relatively cumbersome and prone to malfunctions; in addition, the first connecting line is used to transmit control signals, and the second connecting line is used to transmit media signals. Since the media signal transmitted by the second connecting line is an analog signal, its transmission is easily interfered with, thereby affecting the signal quality.

[0038] As can be seen from the above background technology, the existing shutdown method for computing devices requires manual touch of the shutdown button of the computing device, that is, it is necessary to ensure that the person and the computing device are together, making the shutdown method inflexible, or the computing device needs to be disassembled and wired, which will change the original assembly of the computing device and make the computing device prone to failure. Therefore, the present application provides a shutdown control method, in which the control center can remotely send a first shutdown control instruction to the central control host based on the serial bus, that is, it is not necessary to ensure that the person and the computing device are together, which improves the convenience of shutdown and increases the flexibility of shutdown; then, after the central control host receives the first shutdown control instruction, it sends the first shutdown control instruction to the computing device through the serial bus to instruct the computing device to shut down, that is, the central control host and the computing device are connected through the serial bus, and there is no need to disassemble the computing device for wiring, which is simpler and reduces the failure rate of the computing device, and the media signal and the control signal are both transmitted through the serial bus, without the need for two wires, saving costs and avoiding interference with the media signal transmission.

[0039] Refer to FIG. 2 , which is a schematic diagram of a shutdown control system provided in an embodiment of the present application.

[0040] The shutdown control system shown in Figure 2 includes a central control host, a control center and a computing device; the computing device and the control center are connected via a serial bus; the control center can be a server, such as an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, as well as basic cloud computing services such as big data and artificial intelligence platforms, which are not specifically limited in this application; the control center can also be a mobile terminal such as a smart phone, tablet computer, or laptop computer; the control center and the central control host establish a network communication connection to realize remote communication, and the communication protocol used is not specifically limited in this application; the computing device can be a computer host, etc., and the number of computing devices can be one or more. This application mainly uses one as an example for illustration.

[0041] When the control center is a mobile terminal, a target application is installed on the control center. When the user wants to shut down the computing device, the user can perform a target operation in the target application. The target operation is used to trigger the shutdown of the computing device. Then, the control center responds to the user's target operation and sends a first shutdown control instruction to the central control host. After receiving the first shutdown control instruction, the central control host sends the first shutdown control instruction to the computing device through the serial bus, wherein the first shutdown control instruction is used to instruct the computing device to shut down.

[0042] When the control center is a server, the shutdown control system shown in FIG2 may also include a user terminal, which may also be a mobile terminal such as a smartphone, tablet computer, or laptop computer. A target application is also installed on the user terminal. When a user wants to shut down a computing device, the user may perform a target operation in the target application. The target operation is used to trigger the shutdown of the computing device. The user terminal then responds to the target operation by sending a first shutdown control instruction to the control center. After receiving the first shutdown control instruction from the user terminal, the control center is used to send the first shutdown control instruction to the computing device via a serial bus, wherein the first shutdown control instruction is used to instruct the computing device to shut down. It should be noted that this application is mainly described using the example of a mobile terminal as the control center.

[0043] It should be noted that the control center can remotely send a first shutdown control instruction to the central control host, that is, there is no need to ensure that people and computing devices are together, which improves the convenience of shutdown and increases the flexibility of shutdown; then after the central control host receives the first shutdown control instruction, it sends the first shutdown control instruction to the computing device through the serial bus to instruct the computing device to shut down. In other words, the central control host and the computing device are connected through the serial bus, and there is no need to disassemble the computing device for wiring, which is simpler, and both media signals and control signals are transmitted through the serial bus, without the need for two wires, which saves costs and can also avoid interference with media signal transmission.

[0044] In an optional embodiment, the computing device is installed in a target location (such as a classroom, conference room, etc.). Before the central control host receives the first shutdown control instruction from the control center, the control center is also used to generate the first shutdown control instruction, specifically including: the control center is also used to obtain a usage schedule for the target location; then the control center is also used to determine the target object currently using the target location based on the usage schedule; then the control center is also used to obtain the target object's historical usage record for the target location; then the control center is also used to predict a first moment based on the historical usage record, wherein the first moment is the shutdown time of the computing device; then the control center is also used to generate the first shutdown control instruction based on the first moment. Further, the control center is also used to send the first shutdown control instruction to the central control host, wherein the first shutdown control instruction is used to control the computing device to shut down at the first moment.

[0045] Exemplarily, if the target location is a target classroom, the control center obtains a usage schedule for the target classroom, such as a class scheduling schedule for the target classroom, the class scheduling schedule including the usage time and the user (such as a teacher) of the target classroom, wherein the usage time and the user in the class scheduling schedule are a one-to-one mapping relationship; then the control center determines the target object currently using the target classroom based on the current usage time of the target classroom, the mapping relationship between the usage time and the user of the target classroom in the class scheduling schedule; then the control center obtains a historical usage record of the target object, wherein the historical usage record includes a plurality of actual class ending times corresponding to when the target object was teaching in the target classroom and / or classrooms other than the target classroom; then, the control center predicts a first moment based on the historical usage record, specifically, determines a first number based on the plurality of actual get out of class ending times and the plurality of theoretical get out of class ending times corresponding to the plurality of actual class ending times, wherein the first number is the number of actual get out of class ending times that are later than the corresponding theoretical get out of class ending times. It should be noted that the theoretical get out of class ending time can be determined based on the usage time of the class scheduling schedule, that is, the theoretical get out of class ending time is set in advance of class scheduling.

[0046] The control center then determines a first ratio of the first number to the number of actual get out of class ending times; if the first ratio is greater than or equal to a first preset value, the control center determines the difference between each first actual get out of class ending time in the first number of first actual get out of class ending times and the theoretical get out of class ending time corresponding to each first actual get out of class ending time, obtaining a first difference corresponding to each first actual class ending time, wherein the first actual get out of class ending time in the first number is the get out of class ending time that is later than the corresponding theoretical get out of class ending time among the multiple actual class ending times; the control center then performs a weighted average of the first differences corresponding to each first actual get out of class ending time to obtain a first duration; the control center then determines a first moment based on the first duration and the theoretical class ending time corresponding to the target location for the current target object, for example, the first moment is the sum of the current theoretical get out of class ending time and the first duration. If the first ratio is greater than or equal to a second preset value and less than the first preset value, the control center obtains a preset second duration, and then determines a first moment based on the second duration and the theoretical class ending time corresponding to the target location for the current target object, for example, the first moment is the sum of the current theoretical get out of class ending time and the second duration, wherein the second duration is less than the first duration. If the first ratio is greater than zero and less than the second preset value, the control center obtains the preset third duration, and then determines the first moment based on the third duration and the theoretical get out of class end time corresponding to the current target object using the target location. For example, the first moment is the sum of the current corresponding theoretical get out of class end time and the third duration, wherein the second duration is greater than the third duration and less than the first duration. If the first ratio is equal to zero, the control center determines the first moment as the current corresponding theoretical get out of class end time. The control center then generates a first shutdown control instruction based on the first moment, that is, the first shutdown control instruction includes the first moment; the control center then sends the first shutdown control instruction to the central control host, wherein the first shutdown control instruction is used to control the computing device to shut down at the first moment.

[0047] It should be noted that in this embodiment, before the control center sends the first shutdown control instruction to the central control host, the control center first determines the target object based on the usage plan of the target place, and then the control center predicts the first moment, that is, the shutdown moment of the computing device, based on the historical usage record of the target object. The control center then generates a corresponding first shutdown control command based on the first moment, and then the control center sends the first shutdown control command to the central control host, and the central control host sends the first shutdown control command to the computing device to control the computing device to automatically shut down at the first moment. By analyzing the historical usage records of the current target object, such as whether there are phenomena such as overstaying or delayed classes, the shutdown time of the computing device is adaptively determined, and there is no need for manual shutdown, which improves convenience and avoids the situation where the computing device is not shut down after use, causing the computing device to be idle for a long time and wasting resources.

[0048] In an optional embodiment, after the central control host receives the first shutdown control instruction from the control center, before the central control host sends the first shutdown control instruction to the computing device through the serial bus, the central control host is also used to send a first inquiry request to the computing device, wherein the first inquiry request is used to inquire whether the computing device is allowed to shut down at the first moment. In this embodiment of the present application, the time when the central control host sends the first inquiry request to the computing device is earlier than or equal to the first moment; if the central control host receives a confirmation response to the first inquiry request from the computing device (for example, after receiving the first inquiry request, the computing device can display a shutdown prompt, and then the user, such as a teacher or student, can click to confirm the shutdown, and the computing device sends a confirmation response to the central control host in response to the user's confirmation shutdown operation), the central control host is also used to send the above-mentioned first shutdown control instruction to the computing device through the serial bus to control the computing device to shut down at the first moment.

[0049] If the central control host receives a rejection response to the first inquiry request from the computing device (similarly, for example, after receiving the first inquiry request, the computing device can display a shutdown prompt, and then the user, such as a teacher or student, can click to reject the shutdown, and the computing device sends a rejection response to the central control host in response to the user's rejection of the shutdown operation), the central control host is also used to cache the first shutdown control instruction; then the central control host is also used to send a shutdown inquiry request to the computing device after the target time (used to inquire whether the computing device allows shutdown at the current moment) until a confirmation response to the shutdown inquiry request is received from the computing device for the first time, wherein the target time is determined based on the first moment and the preset time. , that is, the target duration is the sum of the time from the moment when the central control host receives a rejection response to the first inquiry request from the computing device to the first moment and the preset duration, that is, the central control host sending a shutdown inquiry request to the computing device after the target duration can be understood as the central control host sending a shutdown inquiry request to the computing device after the preset duration of the first moment; that is, the central control host sends a shutdown inquiry request to the computing device after the target duration. If the central control host still receives a rejection response to the shutdown inquiry request from the computing device, the central control host sends a shutdown inquiry request to the computing device again after the next preset duration, until the central control host receives a confirmation response to the shutdown inquiry request from the computing device for the first time.

[0050] Then, the central control host is also used to modify the first shutdown control instruction to obtain a second shutdown control instruction. Specifically: the central control host is also used to determine a fourth moment when a confirmation response to the shutdown inquiry request is received from the computing device, and then the central control host is also used to determine the second moment based on the fourth moment. Specifically, the fourth moment can be determined as the second moment, or the fourth moment and the preset safety time threshold can be summed to obtain the second moment; then the central control host is also used to modify the first shutdown control instruction based on the second moment to obtain a second shutdown control instruction, wherein the second shutdown control instruction carries the second moment, and the second shutdown control instruction is used to instruct the computing device to shut down at the second moment; then, the central control host sends the second shutdown control instruction to the computing device through the serial bus to control the shutdown of the computing device.

[0051] It should be noted that in this embodiment, the first moment determined above can be understood as the initial shutdown moment of the computing device; then after receiving the first shutdown control instruction, the central control host first sends a first inquiry request to the computing device to inquire whether the computing device can be shut down at the first moment. If a confirmation response is received, the first shutdown control instruction can be sent to control the computing device to shut down at the first moment; if a rejection response is received, the first shutdown control instruction can be cached first, and then after the preset time length of the first moment, that is, the target time length, the computing device can be asked again whether it can be shut down at present, until the first confirmation response of the computing device is received, the first shutdown control instruction is modified based on the time of the received confirmation response to obtain the second shutdown control instruction, that is, the shutdown time of the computing device is changed, and then the second shutdown control instruction is sent to the computing device, which can avoid incorrect shutdown of the computing device and improve the accuracy of shutdown.

[0052] In an optional embodiment, if the central control host does not receive a response message to the first inquiry request from the computing device (i.e., the central control host does not receive a confirmation response or a rejection response), the central control host determines to perform a default shutdown on the computing device, and then the central control host sends a first shutdown control instruction to the computing device to instruct the computing device to shut down.

[0053] In an optional embodiment, if the central control host does not receive response information to the first inquiry request from the computing device (that is, the central control host does not receive a confirmation response or a rejection response), the central control host is further used to cache the first shutdown control instruction; then the central control host is further used to detect at the first moment whether there is currently media data (such as audio, video, images, etc.) being transmitted with the computing device through the serial bus; if not, the central control host is further used to send the first shutdown control instruction to the computing device through the serial bus to control the computing device to shut down at the first moment; if so, the central control host predicts the transmission time based on the media data currently being transmitted through the serial bus (that is, the media data being transmitted through the serial bus detected at the first moment), where the transmission time is the time required to transmit the media data. Exemplarily, the central control host is used to obtain the remaining amount of data to be transmitted corresponding to the media data currently being transmitted through the serial bus, and to obtain the total amount of data transmitted through the serial bus in each of multiple historical time periods before a first moment; then the central control host determines the average operating frequency corresponding to the serial bus based on the total amount of data transmitted in each historical time period and each historical time period, for example, averaging the ratio of the total amount of data transmitted in each historical time period to each historical time period; then the central control host obtains the bit width of the serial bus; then the central control host determines the data transmission rate of the serial bus based on the bit width of the serial bus and the average operating frequency; then the central control host determines the transmission time based on the remaining amount of data to be transmitted of the serial bus and the data transmission rate, such as the ratio between the two. Then, the central control host modifies the first shutdown control instruction based on the transmission time to obtain a third shutdown control instruction. Specifically, based on the first moment and the transmission time, the third moment is determined, wherein the third moment is the sum of the first moment and the transmission time; or, the sum of the third moment and a preset safety time threshold is used as the new third moment; then the first shutdown control instruction is modified based on the third moment to obtain a third shutdown control instruction, wherein the third shutdown control instruction carries the third moment, and the third shutdown control instruction is used to instruct the computing device to shut down at the third moment; then the central control host is also used to send the third shutdown control instruction to the computing device through the serial bus to instruct the computing device to shut down.

[0054] It should be noted that in this embodiment, if the central control host does not receive a response message to the first inquiry request from the computing device, the first shutdown control instruction is first cached, and then it is detected at the first moment whether the current serial bus is still transmitting media data. If not, the first shutdown control instruction can be directly sent to the computing device to instruct the computing device to shut down; if so, the transmission time required to complete the current transmission of the media data is predicted, and then the first shutdown control instruction is modified based on the transmission time, that is, the shutdown time is modified, thereby improving the accuracy of shutting down the computing device.

[0055] In an optional embodiment, after receiving the third shutdown control instruction and before sending the third shutdown control instruction to the computing device via the serial bus, the central control host is further configured to send a second query request to the computing device after a transmission time, wherein the second query request is configured to inquire whether the computing device allows shutdown at the third time. Furthermore, if the central control host receives a confirmation response to the second query request from the computing device, the central control host sends the third shutdown control instruction to the computing device via the serial bus.

[0056] Similarly, if the central control host receives a rejection response to the second inquiry request from the computing device, it sends a shutdown inquiry request to the computing device after a preset period of time until it receives a confirmation response to the shutdown inquiry request from the computing device for the first time; the third shutdown control instruction is modified to obtain a fourth shutdown control command, and the fourth shutdown control instruction is used to instruct the computing device to shut down at the fifth moment, wherein the determination principle of the fifth moment is similar to the determination principle of the above-mentioned second moment, and the principle of modifying the third shutdown control instruction to obtain the fourth shutdown control command is similar to the principle of modifying the first shutdown control instruction to obtain the second shutdown control instruction, and will not be repeated here; then the central control host sends the fourth shutdown control instruction to the computing device through the serial bus to control the computing device to shut down at the fifth moment.

[0057] Similarly, if the central control host does not receive response information for the second query request from the computing device, the subsequent execution principle is similar to the above principle if no response information for the first query request is received from the computing device, and will not be repeated here.

[0058] It should be noted that in this embodiment, before the third shutdown control instruction is issued, a second inquiry request is first sent to the computing device. When the central control host receives a confirmation response to the second inquiry request, the third shutdown control instruction is sent to the computing device. If a rejection response is received or no response is received, the above embodiment is referred to and executed in the same manner, thereby improving the accuracy of shutting down the computing device and avoiding the situation where the computing device is left on standby for a long time without being shut down after it has ended use.

[0059] In an optional embodiment, before the central control host sends a target signal to the computing device, that is, when the central control host is about to send a target signal to the computing device, if the central control host receives a request information for establishing a connection from the computing device (wherein the request information is used to request to establish a connection with the central control host to transmit data), the central control host sends an interrupt command to the computing device, where the interrupt command is used to instruct the computing device to interrupt data transmission, where the target signal is one of the above-mentioned first shutdown control instruction, second shutdown control instruction, third shutdown control instruction, and fourth shutdown control instruction; then the central control host sends the target signal to the computing device through the serial bus.

[0060] In an optional embodiment, the central control host is connected to a power source (such as the AC power supply of the computing device) and supplies power to the computing device (such as the central control host supplies power to the computing device through a cable connection). Therefore, after the central control host sends a shutdown control instruction (such as a first shutdown control instruction, a second shutdown control instruction, a third shutdown control instruction, and a fourth shutdown control instruction) to the computing device, the central control host is also used to detect the voltage of the technical device through the interface of the serial bus; if the voltage meets a preset condition (such as zero), the central control host stops supplying power to the computing device, that is, the computing device is powered off. It should be noted that in this embodiment, after the central control host sends a shutdown control instruction to the computing device, the power supply of the computing device is detected through the serial bus. In essence, the purpose is to detect whether the computing device has been shut down. If the preset condition is met, it means that the computing device has been shut down. At this time, the central control host can no longer supply power to the computing device, that is, turn off the power of the computing device, to avoid the computing device being powered off before it is completely shut down, thereby damaging the computing device.

[0061] In an optional embodiment, since the central control host is connected to a power source and provides power to the computing device, before the central control host receives the first shutdown control command from the control center, the central control host is also used to connect to a power source and provide power to the computing device. The computing device then executes the power-on command after detecting the power source. In other words, when the central control host begins to power the computing device, the computing device automatically executes the power-on command after it is powered on, eliminating the need for manual operation to power on the computing device, thereby increasing convenience.

[0062] Based on the shutdown control system in the above embodiment, the following scenario will be illustrated by taking the control center as a server as an example, referring to FIG3 , which is a schematic diagram of a shutdown control scenario provided in an embodiment of the present application.

[0063] The scenario shown in Figure 3 includes a server, multiple central control hosts (i.e., central control host 1, central control host 2, ..., central control host n), and multiple computing devices corresponding to the multiple central control hosts (i.e., computing device 1, computing device 2, ..., computing device n); wherein, each central control host and the corresponding computing device are connected via a serial bus, and each central control host and the corresponding computing device are installed in each target location (classroom 1, classroom 2, ..., classroom n, in that order).
