Description

Technical Field

[0001] The present application relates to the field of computer security technology, and in particular to a protection method and device for an OPS system and an all-in-one education or conference machine. Background Art

[0002] At present, there are many kinds of intelligent terminal devices on the market, such as home TVs, office personal computers or educational all-in-one computers used in educational scenarios. With the widespread application of these terminal devices, the corresponding Open Pluggable Specification (OPS) system is also widely used. OPS is a standardized digital signage interface specification jointly formulated by Intel and display manufacturers. Its internal structure is a mini computer with X86 architecture, equipped with memory, hard disk, multiple input and output interfaces and Windows operating interface. The OPS system is connected to the intelligent terminal device through pins.

[0003] However, since the connection method between the terminal device and the OPS system and the pins used for connection are all specified by the protocol standard, it is impossible to adaptively deploy the corresponding detection or control strategy. Accordingly, the security of the system cannot be guaranteed. The solution to the security problem in the prior art is to manually discover problems in the operation of the OPS system and return it to the factory for repair. This method is not only inefficient, but also affects the user experience. Summary of the invention

[0004] In an exemplary embodiment of the present application, a protection method, device and an all-in-one education or conference machine for an OPS system are provided to quickly discover problems that occur during the operation of the OPS and solve the problems in a timely manner.

[0005] In a first aspect, an embodiment of the present application provides a method for protecting an OPS system, the method being applied to a terminal device connected to an open pluggable specification OPS system, the method comprising:

[0006] When the program in the OPS system is running, a display signal from the OPS system is received, and keep-alive information fed back by the OPS system is obtained; the keep-alive information is used to indicate that the OPS system is running normally;

[0007] If the duration of not obtaining the keep-alive information reaches a first preset duration, or the duration of not receiving the display signal reaches a second preset duration, it is determined that the OPS system is not operating normally;

[0008] Instruct the OPS system to enter recovery mode.

[0009] In the scenario where the OPS system is connected to a terminal device, this application proposes to lock the operation problem of the OPS system by using the display signal and keep-alive information sent during the operation of the OPS system program, so as to efficiently and quickly discover problems with the OPS system. After discovering a problem, the terminal device can automatically instruct the OPS system to enter the recovery mode, and the problems of the OPS system can be solved without manual intervention.

[0010] In some embodiments, before instructing the OPS system to enter the recovery mode, the method further includes:

[0011] Sending instruction information for instructing a power-on reset to the OPS system, and continuing to receive the display signal and obtain the keep-alive information;

[0012] If the heartbeat information is still not received within the first preset duration after sending the instruction information, or the display signal is still not received within the second preset duration after sending the instruction information, it is determined that the OPS system is still not operating normally;

[0013] Returning to execute the step of sending the instruction information to the OPS system until the number of times of executing the step of sending the instruction information reaches the set number of times.

[0014] Based on the above solution, before instructing the OPS system to enter the recovery mode, the terminal device can first instruct the OPS system to perform several power-on resets. The power-on reset can solve general system crash problems. If the power-on reset still cannot solve the problems of the OPS system, then perform the operation of instructing it to enter the recovery mode. Solving the problems of the OPS system through two-level processing improves the reliability of the OPS system.

In addition, the term "comprising" and any variations thereof are intended to cover non-exclusive protection. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices. "Multiple" in this application may mean at least two, for example, it may be two, three or more, and the embodiments of this application do not make limitations.

[0091] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after without special explanation.

[0092] To facilitate the understanding of the solution proposed in this application, the technical terms involved in this application are briefly introduced first:

[0093] (1) Open Pluggable Specification (OPS) system: It is a computing module plug-in used to increase the computing power of the electronic device connected to it. Its internal structure is a mini computer with an X86 architecture, configured with memory, hard disk, multiple input and output interfaces, and a Windows operating interface. The OPS system is connected to the electronic device through pins, and the functions of each pin used are defined in the standard, and it also includes multiple reserved pins that are not used and not defined in the standard.

[0094] (2) Interactive flat panel for education: It is an electronic device for teaching, integrating technologies such as multi-touch, artificial intelligence, and cloud computing, and is generally configured with an Android system. When used in conjunction with the OPS system, it can implement dual systems of Android and Windows. The interactive flat panel for education equipped with the OPS system can run Android version programs and Windows version programs during use. Optionally, for the convenience of understanding how the interactive flat panel for education connected to the OPS system implements running dual systems, reference can be made to Figure 1 , which is a display interface for the startup of an interactive flat panel for education provided by the embodiments of this application, and users can select the system program to run according to this display interface.

[0095] The protection method of the OPS system proposed in this application is applicable to scenarios where some non-Windows system terminal devices are connected to the OPS system. To facilitate understanding of the solution proposed in this application, the system architecture applicable to this application is first introduced. Exemplarily, see Figure 2 , which is a schematic diagram of a system architecture provided by an embodiment of this application. It should be understood that the embodiments of this application are not limited to Figure 2 the system shown. Figure 2 It includes a terminal device and an OPS system. Optionally, Figure 2 the terminal device shown in Figure 2 can be a terminal device using a non-Windows system such as a TV, an education all-in-one machine, or a conference all-in-one machine. Optionally, see Figure 2 In Figure 3 , which is a schematic diagram of a JAE standard plug provided by an embodiment of this application. Optionally, in Figure 2 the definitions of pin signals specified in some protocols are also shown. There are some reserved pins in the pins connecting the terminal device and the OPS system that are not defined in the protocol. For example, see Table 1 below, which are reserved pins not defined in the standard.

[0096] Table 1

[0097] 49 Reserved (RSVD) Reserved Pins 48 RSVD Reserved Pins 47 RSVD Reserved Pins 46 RSVD Reserved Pins 45 RSVD Reserved Pins 44 RSVD Reserved Pins 43 RSVD Reserved Pins 42 RSVD Reserved Pins 41 RSVD Reserved Pins

[0098] In the related art, if two interconnected devices need to perform keep-alive, generally, adaptive configuration is performed on the two devices, and different strategies are designed to be executed in different operating states to ensure that the two systems can timely know the operating states of each other. However, this adaptive definition method is not applicable to the OPS system. For a device with a standard definition like the OPS system, adaptive adjustment cannot be achieved. In view of this, the embodiments of this application provide a protection method for the OPS system. When the terminal device runs a program in the OPS system, the OPS system is kept alive (that is, it is determined whether the OPS system is running normally) according to the display signal sent by the OPS system and the feedback keep-alive information. When it is determined that there is a problem with the operation of the OPS system, the OPS system can also be automatically instructed to enter the recovery mode to solve problems such as abnormal power-off, systematic crash, system loss, or hot plugging of the OPS.

[0099] To facilitate understanding of the method proposed in this application, the protection method of the OPS system proposed in this application is introduced below in combination with Figure 2 the system architecture shown. See Figure 4, which is a flowchart of a protection method for an OPS system provided by an embodiment of the present application. Optionally, this method flow can be executed by a terminal device connected to the OPS system. The method flow specifically includes:

[0100] 401. When the terminal device runs a program in the OPS system, it receives a display signal from the OPS system and obtains keep-alive information fed back by the OPS system.

[0101] Among them, the keep-alive information is used by the OPS system to indicate that it is running normally. Optionally, the keep-alive information can be periodically fed back by the OPS system to the terminal device.

[0102] Optionally, the terminal device running the program in the OPS system can be that the terminal device responds to the user's operation of selecting the OPS system on the display interface as shown in Figure 1 and executes the program of running the OPS system. During the process of running the program in the OPS system, the OPS system can send display information to the terminal device in real time, such as a High Definition Multimedia Interface (HDMI) display signal, for the terminal device to display the corresponding program interface on the display screen.

[0103] 402. If the duration for which the terminal device does not obtain the keep-alive information reaches a first preset duration, or the duration for which it does not receive the display signal reaches a second preset duration, it is determined that the OPS system is not running normally.

[0104] Optionally, during the process of the terminal device running the program in the OPS system, it continuously counts the time when it does not receive the keep-alive information and the display signal. If the terminal device does not obtain the keep-alive information for a continuous period of time, and the duration of this continuous period reaches the first preset duration, it can be determined that there is a problem with the operation of the OPS system. Or, if the terminal device does not receive the display signal for a continuous period of time, and the duration of this continuous period reaches the second preset duration, it can also be determined that there is a problem with the operation of the OPS system.

[0105] 403. The terminal device instructs the OPS system to enter the recovery mode.

[0106] Specifically, after the terminal device determines that the OPS system is not running normally, it can instruct it to enter the recovery mode to restore the OPS system to the backed-up initial system, thereby solving problems such as system loss and ensuring the reliability of the OPS system.

[0107] In the scenario where the OPS system is connected to the terminal device, this application proposes to lock the operation problem of the OPS system through the display signal and keep-alive information sent during the operation of the OPS system program, so as to efficiently and quickly discover the problems of the OPS system. After discovering the problem, the terminal device can automatically instruct the OPS system to enter the recovery mode, and the problems of the OPS system can be solved without manual intervention.

[0108] In some embodiments, the terminal device can obtain the keep-alive information of the OPS system in the following manner. For example, in some cases, the terminal device can receive the heartbeat information periodically sent by the OPS system through the first reserved pin. Optionally, the first reserved pin can be any one of the pins in Table 1 above, that is, any one of the multiple pins not defined in the protocol. The terminal device can determine that it has received the keep-alive information when it periodically receives the heartbeat information. For example, the OPS system can send the heartbeat information to the terminal device every 10 seconds. The terminal device can determine that there is a problem with the operation of the OPS system when it does not receive the heartbeat information sent by the OPS system for three consecutive cycles (30 seconds).

[0109] In other cases, the terminal device can detect the level of the first reserved pin. When it detects that the level of the first reserved pin changes periodically, for example, when the level of the first reserved pin becomes a certain preset value every other cycle, or when the level of the first reserved pin increases and is greater than a certain preset value every certain cycle, the terminal device can consider that it has obtained the keep-alive information of the OPS system. Then, when the terminal device does not detect a change in the level of the first reserved pin for a period of time, it can be considered that there is a problem with the operation of the OPS system. For example, the OPS system can periodically raise the level of the first reserved pin, such as raising the level of the first reserved pin every 10 seconds. Then, when the terminal device does not detect the high level of the first reserved pin for 30 consecutive seconds, it can be considered that there is a problem with the operation of the OPS system.

[0110] In some scenarios, after determining that there is a problem with the operation of the OPS system based on the keep-alive information or the display signal, the terminal device may first instruct the OPS system to power on several times before instructing it to enter the recovery mode. In a possible implementation manner, after determining that there is a problem with the operation of the OPS system, the terminal device may send instruction information for instructing a power-on to the OPS system and continue to receive the display signal and obtain the keep-alive information. If the keep-alive information is still not obtained within the first preset duration after sending the instruction information, it may be determined that the OPS system is still not operating properly. Alternatively, if the terminal device still does not receive the display signal within the second preset duration after sending the instruction information, it may also be determined that the OPS system is still not operating properly. After determining that the OPS system is still not operating properly after a power-on, the terminal device may send the instruction information for instructing a power-on to the OPS system again. After repeating the set number of times and determining that the OPS system is still not operating properly, the terminal device then instructs the OPS system to enter the recovery mode. To further understand the method for solving the problem of the operation of the OPS system proposed in this application, the following will be introduced in combination with specific embodiments. Refer to Figure 5 , which is a flowchart of a method for solving the problem of the operation of the OPS system provided by an embodiment of the present application, specifically including:

[0111] 501. The terminal device determines that the operation of the OPS system is abnormal.

[0112] Optionally, the method for the terminal device to determine that the operation of the OPS system is abnormal may refer to the introduction in the above-mentioned embodiments in China, and will not be elaborated here.

[0113] 502. The terminal device sends instruction information for instructing a power-on to the OPS system.

[0114] 503. After sending the instruction information, the terminal device continues to obtain the keep-alive information fed back by the OPS system and the display signal sent by the OPS system.

[0115] 504. The terminal device determines whether the OPS system is operating properly after sending the instruction information.

[0116] Specifically, if the terminal device still does not obtain the keep-alive information fed back by the OPS system within the first preset duration after sending the instruction information, or still does not receive the display information within the second preset duration after sending the instruction information, it may be determined that the OPS system is not operating properly. On the contrary, if the terminal device receives the display information and obtains the keep-alive information after sending the instruction information, it may be considered that the OPS system is operating properly.

[0117] If the terminal device determines that the OPS system is operating properly, no operation may be performed.

[0118] If the terminal device determines that the OPS system is not running properly, it can continue with step 505.

[0119] 505. The terminal device determines whether the number of times of sending the indication information has reached a preset number of times.

[0120] If the preset number of times is reached, continue with step 506.

[0121] If the preset number of times is not reached, return to step 502 for execution.

[0122] 506. The terminal device instructs the OPS system to enter the recovery mode.

[0123] Based on the above solution, before the terminal device instructs the OPS system to enter the recovery mode, it can first instruct the OPS system to power on several times. Powering on can solve general system crash and other problems. If powering on still cannot solve the problems of the OPS system, then perform the operation of instructing it to enter the recovery mode. Solving the problems of the OPS system through two-level processing improves the reliability of the OPS system.

[0124] Optionally, the terminal device can instruct the OPS system to enter the recovery mode in the following manner. In one possible implementation, the terminal device can send an instruction for instructing to enter the recovery mode to the OPS system through the second reserved pin. After receiving the instruction, the OPS system enters the recovery mode. Among them, the second reserved pin is any one of the multiple reserved pins other than the first reserved pin.

[0125] In another possible implementation, the terminal device can also modify the level of the second reserved pin. For example, the level of the second reserved pin can be modified to a certain set value. Or, if the second reserved pin is normally at a high level (higher than a certain value), the terminal device can instruct the OPS system to enter the recovery mode by lowering the level of the second reserved pin (lower than a certain value). When the OPS system monitors the change in the level of the second reserved pin, it can enter the recovery mode.

[0126] Next, in order to further understand the protection method of the OPS system provided in the embodiments of the present application, it will be introduced in combination with specific embodiments. Refer to Figure 6 , which is a flowchart of a protection method for an OPS system provided in an embodiment of the present application, specifically including:

[0127] 601. The terminal device detects that the OPS system is successfully connected.

[0128] Optionally, the terminal device can detect the OPS system through, for example Figure 3The plug-in shown is successfully connected to the terminal device to determine successful connection to the OPS system. For example, it can be determined that the OPS system is successfully connected by detecting whether the protocol calibration parameter PB_DET is low. If it is low, it can be determined that the OPS system is successfully connected.

[0129] 602. The terminal device instructs the OPS system to power on.

[0130] Optionally, the terminal device can instruct the OPS system to power on by sending a protocol calibration signal PS_ON to the OPS system. Further, after the OPS system is successfully powered on, it can feedback a protocol calibration signal PWR_GOOD to the terminal device to indicate successful power on.

[0131] 603. The terminal device obtains the keep-alive information and display signal of the OPS system.

[0132] 604. The terminal device determines whether the OPS system is operating normally.

[0133] Optionally, the process by which the terminal device determines the operating state of the OPS system according to the keep-alive information and display signal can refer to the introduction in the above embodiments and will not be elaborated here.

[0134] If so, return to step 603.

[0135] If not, continue with step 605.

[0136] 605. The terminal device instructs the OPS system to perform a power-on process a set number of times.

[0137] Specifically, it can refer to the relevant introduction in the above Figure 5 and will not be elaborated here.

[0138] 606. The terminal device continues to determine whether the OPS system is operating normally.

[0139] If so, return to step 603.

[0140] If not, continue with step 607.

[0141] 607. The terminal device instructs the OPS system to enter the recovery mode.

[0142] Optionally, the specific indication method can refer to the introduction in the above embodiments.

[0143] Based on the same concept as the above method, refer to Figure 7 , a protection device 700 for an OPS system provided by an embodiment of the present application. The device 700 is used to execute each step in the above method. To avoid repetition, it will not be elaborated here. The device 700 includes: a communication unit 701 and a processing unit 702.

[0147] Obtain keep-alive information fed back by the OPS system; the keep-alive information is used to indicate that the OPS system is running normally;

[0148] When the duration of not obtaining the keep-alive information reaches a first preset duration, or when the duration of not receiving the display signal reaches a second preset duration, determine that the OPS system is not running normally;
