[0093] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments made by ordinary technicians in this field under the enlightenment of the embodiments belong to the scope of protection of the present application.

[0094] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0095] With the development of science and technology, the number and types of business equipment used by people are increasing. In the process of using business equipment, it is inevitable that failures will occur and they need to be repaired. After the repair is completed, in order to determine the effect of the repair, it needs to be tested.

[0096] In the prior art, when testing, the operation mode of the service device needs to be switched to the test mode before the test can be performed. In the process of mode switching, the service device needs to be disassembled, and the corresponding physical interface needs to be welded on the mainboard of the test device. The test device and the service device are connected through the physical interface so that the two can communicate. Then the test device sends a test instruction to the service device, and the service device switches its own operation mode to the test mode, and then the test device can test the service device.

[0097] Since the business equipment needs to be disassembled and the physical interface needs to be welded, the efficiency of mode switching will be low.

[0098] In view of the problems existing in the prior art, the inventors found in the process of studying mode switching that in order to improve the efficiency of mode switching, the business device can open the communication port, and then establish a communication connection with the test device through the port to achieve communication. Then, through the communication connection, the business device obtains the mode variable from the test device and stores it. Then, after the business device is restarted, it can enter the test mode according to the mode variable, without disassembling the machine and welding the interface, which effectively improves the efficiency of mode switching. Based on the above invention concept, the mode switching scheme in this application is designed.

[0099] In the present application, the business equipment may be a display device, a camera, a server, etc., and the test equipment may be a computer, a server, a terminal device, etc. The present application embodiment does not limit the business equipment and the test equipment, which may be determined according to actual conditions.

[0100] The following is an example of an application scenario of the mode switching method provided in this application.

[0101] For example, in this application scenario, a service device fails and needs to be tested after repair. After the service device is started, it determines which mode to enter based on whether it stores a mode variable. After entering the user mode, the communication port is opened.

[0102] Then, within the preset timeout period, the service device will wait for the test device to send a communication connection request to it.

[0103] When the test device obtains the test instruction, it sends a communication connection request to the business device.

[0104] If the service device receives a communication connection request sent by the test device through the communication port within a preset timeout period, a communication connection is established with the test device.

[0105] The business device obtains and stores the mode variables from the test device through the communication connection. Then the business device restarts and enters the test mode according to the obtained mode variables.

[0106] After the service equipment enters the test mode, the test equipment can start testing.

[0107] It should be noted that the above scenario is only an example of an application scenario provided by an embodiment of the present application. The embodiment of the present application does not limit the actual form of the various devices included in the scenario. In the specific application of the solution, it can be set according to actual needs.

[0108] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0109] Figure 1 This is a flow chart of the first embodiment of the mode switching method provided by the present application. The present embodiment of the present application describes the situation in which the business device and the test device establish a communication connection through the test interface, and then the business device switches the mode according to the mode variables obtained through the communication connection. The method in this embodiment can be implemented by software, hardware, or a combination of software and hardware. Figure 1 As shown, the mode switching method specifically includes the following steps:

[0110] S101: When the operation mode of the service device is user mode, the communication port is enabled.

[0111] After the business device is started, the business device will determine whether to enter the user mode or the test mode based on whether it has stored the mode variable. Since the business device is in a state of being repaired and needs to be tested, the mode variable is not stored and the operating mode is determined to be the user mode.

[0112] In this step, when the operation mode of the service device is user mode, in order to enter the test mode, the communication port needs to be opened.

[0113] It should be noted that the port number of the communication port is a preset port number, which may be 7000, 8000, 9000, etc. The embodiment of the present application does not limit the preset port number and may be set according to actual conditions.

[0114] S102: In response to the acquired test instruction, the test device sends a communication connection request to the service device through the communication port opened by the service device.

[0115] In this step, in order to test the service device, when the test device obtains the test instruction, it sends a communication connection request to the service device through the communication port opened by the service device in response to the obtained test instruction.

[0116] It should be noted that the test device may obtain the test instruction in the following manner: when the test device is started, the test device automatically generates the test instruction, and the test instruction can be obtained; or the test device generates the test instruction in response to the user's operation by clicking the test button on the graphical user interface of the test device; or the test device may receive the test instruction after receiving the test instruction from the third-party device. The embodiment of the present application does not limit the manner in which the test device obtains the test instruction, and it can be determined according to the actual situation.

[0117] S103: If the service device receives a communication connection request sent by the test device through the communication port within a preset timeout period, a communication connection is established with the test device.

[0118] In this step, after opening the communication port, the service device will wait for the test device to send a communication connection request within a preset timeout period.

[0119] If a communication connection request sent by the test device is received through the communication port within the preset timeout period, it means that the business device needs to be tested, and then the business device establishes a communication connection with the test device.

[0120] If no communication connection request is received from the test device through the communication port within the preset timeout period, it means that no test is needed. In order to ensure the security of the business equipment and prevent malicious elements from attacking the business equipment through the communication port, the communication port needs to be closed.

[0121] It should be noted that the preset timeout period can be 30 seconds, 1 minute, 5 minutes, etc. The embodiment of the present application does not limit the preset timeout period and can be set according to actual conditions.

[0122] It should be noted that the connection method between the business device and the test device can be a wireless connection or a wired connection through a network cable. The embodiment of the present application does not limit the connection method between the business device and the test device, which can be determined according to actual conditions.

[0123] It should be noted that the communication connection may be a socket connection.

[0124] S104: The service device obtains and stores the pattern variables from the test device through the communication connection.

[0125] In this step, after the service device establishes a communication connection with the test device, the service device needs to obtain and store the mode variable from the test device through the communication connection in order to enter the test mode after restart. The mode variable is used to indicate whether the operation mode of the service device after restart is the test mode or the user mode.

[0126] The business device will send a variable acquisition instruction to the test device through a communication connection, and then the test device will send the mode variable to the business device when receiving the variable acquisition instruction sent by the business device.

[0127] It should be noted that the variable value of the mode variable sent by the test device to the business device is a preset variable value, which can be 0, 1, 2, etc. The embodiment of the present application does not limit the preset variable value and can be set according to actual conditions.

[0128] S105: Restart the service equipment.

[0129] In this step, after the service device stores the mode variables, it needs to be restarted in order to enter the test mode, so that the operation mode can be determined according to the test variables later.

[0130] S106: When the mode variable indicates that the operation mode is the test mode, the service device enters the test mode.

[0131] In this step, after the service device is restarted, when the mode variable indicates that the operating mode is the test mode, the service device enters the test mode.

[0132] After the business device is restarted, it will determine whether it has stored the mode variable. If the mode variable is not stored, it will enter the user mode. If the mode variable is stored, it will continue to determine whether the variable value of the mode variable is the preset variable value; if the variable value is not the preset variable value, it will enter the user mode; if the variable value is the preset variable value, it indicates that the operating mode is the test mode, and then it will enter the test mode.

[0133] Because the business device has stored the mode variable at this time, and the variable value of the mode variable is the preset variable value, the test mode is entered.

[0134] After the service equipment enters the test mode, the test equipment can test the service equipment.

[0135] The mode switching method provided in this embodiment opens the communication port when the operating mode of the business device is the user mode. The test device sends a communication connection request to the business device through the communication port; then the business device establishes a communication connection with the test device. The business device then obtains and stores the mode variable from the test device based on the communication connection. After the business device is restarted, when the mode variable indicates that the operating mode is the test mode, it enters the test mode. Compared with the prior art that requires disassembly and welding of physical interfaces, this solution establishes a communication connection and completes mode switching according to the mode variables. There is no need to disassemble the business device or weld the physical interface, which effectively improves the efficiency of mode switching and reduces costs.

[0136] Figure 2 This is a flow chart of the second embodiment of the mode switching method provided by the present application. Based on the above embodiment, the present embodiment of the present application describes the situation where the service device and the test device interact through a communication connection, and the service device obtains and stores the mode variable. Figure 2 As shown, the mode switching method specifically includes the following steps:

[0137] S201: The test device sends an identity authentication instruction to the business device through a communication connection.

[0138] In this step, after the test device establishes a communication connection with the service device, in order for the service device to subsequently verify whether the identity of the test device is correct, it is necessary to send an identity authentication instruction to the service device through the communication connection.

[0139] S202: After receiving the identity authentication instruction sent by the test device through the communication connection, the service device interacts with the test device to verify the test device and obtain a verification result.

[0140] In this step, after the test device sends an identity authentication instruction to the service device, the service device can receive the identity authentication instruction and then interact with the test device through a communication connection to obtain a test result. The verification result is used to indicate whether the verification is passed or not.

[0141] S203: The service device determines whether the verification result indicates that the verification is passed; if the verification result indicates that the verification is passed, step S203 is executed; if the verification result indicates that the verification is not passed, step S204 is executed.

[0142] In this step, after the service device obtains the verification result, in order to determine whether to obtain the mode variable or close the communication port in the future, it is necessary to determine whether the verification result indicates that the verification is passed.

[0143] S203: The service device sends a variable acquisition instruction to the test device.

[0144] In this step, if the verification result indicates that the verification is successful, it means that there is no problem with the identity of the test device and it is safe to obtain the mode variable from the test device, so the business device sends a variable acquisition instruction to the test device through the communication connection.

[0145] S204: The service device disconnects the communication connection and closes the communication port.

[0146] In this step, if the verification result indicates that the verification has not passed, it means that there is a problem with the identity of the test device. In order to ensure the security of the business device, the business device needs to disconnect the communication connection and close the communication port.

[0147] S205: After receiving the variable acquisition instruction sent by the service device, the test device sends the mode variable to the service device.

[0148] In this step, after the service device sends the variable acquisition instruction to the test device, the test device can receive the variable acquisition instruction and then send the pattern variable to the service device through the communication connection.

[0149] S206: The service device receives and stores the mode variable sent by the test device.

[0150] In this step, after the test device sends the mode variable to the service device, the service device can receive the mode variable and then store the mode variable so as to enter the test mode after a subsequent restart.

[0151] The mode switching method provided in this embodiment authenticates the test device through the business device. After the authentication is passed, the business device obtains the mode variables through the test device for storage, thereby ensuring the accuracy and security of the mode variables and improving the security of the business device.

[0152] Figure 3 This is a flow chart of the third embodiment of the mode switching method provided by the present application. Based on the above embodiments, the present embodiment of the present application describes the interaction between the service device and the test device and the verification of the test device. Figure 3 As shown, the mode switching method specifically includes the following steps:

[0153] S301: The service device generates a random number.

[0154] In this step, after the service device receives the identity authentication instruction sent by the test device, it needs to verify the test device and first generate a random number.

[0155] S302: The service device encodes the random number to obtain a first character string.

[0156] S303: The service device sends the first character string to the test device through the communication connection.

[0157] In the above steps, after the service device generates a random number, it encodes it for the convenience of transmission to obtain a first character string, and then sends the first character string to the test device through a communication connection.

[0158] It should be noted that the method for encoding the random number can be: encoding using base64; it can also be encoding using base32 encoding, shellcode encoding, etc. The embodiment of the present application does not limit the method for encoding the random number, which can be determined according to actual conditions.

[0159] S304: After receiving the first character string sent by the service device through the communication connection, the test device decodes the first character string to obtain a random number.

[0160] In this step, after the service device sends the first character string to the test device, the test device can receive the first character string and then decrypt it to obtain a random number.

[0161] S305: The test device encrypts the random number using the private key to obtain an encrypted value.

[0162] In this step, after the test device obtains the random number, it uses the private key to encrypt it to obtain an encrypted value.

[0163] It should be noted that the encryption method is asymmetric encryption, and the RSA method can be used for encryption, or the Digital Signature Algorithm (DSA), Elliptic Curve Cryptosystems (ECC), and other methods can be used for encryption. This application does not limit the encryption method, which can be determined according to actual conditions.

[0164] S306: The testing device encodes the encrypted value to obtain a second character string.

[0165] S307: The test device sends the second character string to the service device through the communication connection.

[0166] In the above steps, in order to facilitate transmission, the test device encodes the encrypted value to obtain a second character string, and then sends the second character string to the service device through the communication connection.

[0167] S308: After receiving the second character string sent by the business device through the communication connection, the business device decodes the second character string to obtain an encrypted value.

[0168] In this step, after the test device sends the second character string to the service device, the service device can receive the second character string and then decode it to obtain an encrypted value.

[0169] S309: The business device uses the public key to decrypt the encrypted value to obtain a verification value.

[0170] In this step, after the service device obtains the encrypted value, it uses the public key to decrypt the encrypted value to obtain the verification value, so that the test device can be verified based on the verification value later.

[0171] S310: The service device determines whether the verification value is the same as the random number; if the verification value is the same as the random number, execute step S311; if the verification value is different from the random number, execute step S312.

[0172] S311: The business device generates a verification result indicating that the verification has passed.

[0173] S312: The business device generates a verification result indicating that the verification failed.

[0174] In the above steps, after the service device obtains the verification value, it determines whether the verification value is the same as the random number.

[0175] If the verification value is the same as the random number, it means that there is no problem with the identity of the test device, and a verification result of verification passing is generated.

[0176] If the verification value is different from the random number, it indicates that there is a problem with the identity of the test device, and a verification result indicating that the verification failed is generated.

[0177] The mode switching method provided in this embodiment generates a random number through a business device, and encodes it to obtain a first character string. The test device decodes, encrypts, and encodes the first character string to obtain a second character string. The business device decodes and decrypts the second character string to obtain a verification value, and then compares it with the random number to determine whether the two are the same, thereby obtaining a verification result. This not only ensures the accuracy of the verification result, but also improves the security of the business device.

[0178] Figure 4 This is a flow chart of the fourth embodiment of the mode switching method provided by the present application. Based on the above embodiment, the present embodiment of the present application describes the situation where the operating mode is determined according to the mode variable each time the service device is started. Figure 4 As shown, the mode switching method specifically includes the following steps:

[0179] S401: Determine whether the mode variable is stored in the service device; if the mode variable is not stored in the service device, execute step S403; if the mode variable is stored in the service device, execute step S402.

[0180] Each time the service device is started, the operation mode is determined according to whether the mode variable is stored in the service device, and the operation mode is the user mode or the test mode.

[0181] In this step, when the service device is started, it is first determined whether the mode variable has been stored in the service device.

[0182] It should be noted that starting a business device includes restarting the business device.

[0183] S402: Determine whether the variable value of the pattern variable is a preset variable value; if the variable value of the pattern variable is not the preset variable value, execute step S403; if the variable value of the pattern variable is the preset variable value, execute step S404.

[0184] In this step, if the mode variable is stored in the service device, in order to prevent an unauthorized person from forging the mode variable to make the service device enter the test mode, it is also necessary to determine whether the variable value of the mode variable is a preset variable value.

[0185] S403: Determine that the operating mode is the user mode.

[0186] In this step, if the mode variable is not stored in the service device, it means that the user mode needs to be entered, and then it is determined that the operation mode is the user mode.

[0187] If the variable value of the mode variable is not the preset variable value, it means that the mode variable may be forged by an unknown molecule. At this time, it is necessary to enter the user mode, and then it is determined that the running mode is the user mode.

[0188] S404: Determine that the operation mode is the test mode.

[0189] In this step, if the variable value of the mode variable is a preset variable value, it means that it is safe to enter the test mode, and then it is determined that the operating mode is the test mode.

[0190] The mode switching method provided in this embodiment determines the operating mode by judging whether the mode variable has been stored in the business device and judging whether the variable value of the mode variable is a preset variable value, thereby making the operating mode more accurate and ensuring the safety of entering the test mode.

[0191] Figure 5 This is a flow chart of the fifth embodiment of the mode switching method provided by the present application. Based on the above embodiment, the present embodiment of the present application describes the situation of deleting the mode variable and closing the communication port after the test is completed. Figure 5 As shown, the mode switching method specifically includes the following steps:

[0192] S501: When the test is finished, the test device sends a variable deletion instruction to the service device.

[0193] In this step, after the service device enters the test mode, the test device tests the service device. After the test is completed, in order to ensure that the service device can enter the user mode when it is started next time, a variable deletion instruction needs to be sent to the service device.

[0194] S502: After receiving the variable deletion instruction sent by the test device, the service device deletes the mode variable.

[0195] In this step, after the test device sends a variable deletion instruction to the service device, the service device may receive the instruction and delete the stored pattern variables.

[0196] S503: The service device disconnects the communication connection and closes the communication port.

[0197] In this step, after the test device sends a variable deletion instruction to the service device, in order to ensure the security of the service device, the service device needs to disconnect the communication connection and close the communication port.

[0198] It should be noted that the execution order of the business device deleting the mode variable and step S503 can be: first execute the mode variable, then execute step S503; it can also be: first execute step S503, then execute the mode variable; it can also be: delete the mode variable and step S503 are executed simultaneously. The embodiment of the present application does not limit the execution order of the business device deleting the mode variable and step S503, which can be determined according to actual conditions.

[0199] After the business device deletes the mode variable, disconnects the communication connection, and closes the communication port, it can be restarted. Since the mode variable is no longer stored at this time, it will enter the user mode.

[0200] The mode switching method provided in this embodiment ensures that the business device can enter the user mode when it is started next time, and also ensures the security of the business device, by having the business device delete the mode variable, disconnect the communication connection, and close the communication port after the test is completed.
