s101: and receiving a remote diagnosis operation notification sent by the user terminal.
In a specific implementation scenario, a device to be maintained receives a remote diagnosis operation notification sent by a user terminal, where the remote diagnosis operation notification is sent to the device to be maintained by starting a client application on the user terminal when a user finds that the device to be maintained is abnormal in operation. In this implementation scenario, the user terminal is a terminal installed with an application program associated with a device to be maintained, such as a computer, a smart phone, a tablet computer, and the like. In other implementation scenarios, the system can also be a controller or an integrated circuit connected with the terminal to be maintained in a wired or wireless manner.
In the implementation scenario, one device to be maintained is associated with one client application, in other implementation scenarios, multiple devices to be maintained of the same brand or the same function, or all devices to be maintained are associated with the same client application, a user selects a device currently needing diagnosis after opening the client application, and then performs an operation of sending a remote diagnosis operation notification under an item of the device currently needing diagnosis, so that the remote diagnosis operation notification is sent to the device currently needing diagnosis.
In the present implementation scenario, the diagnostic device is an embedded terminal, and in other implementation scenarios, the diagnostic device may be various intelligent terminals that can be networked.
S102: and responding to the remote diagnosis operation notice and judging whether to allow the remote diagnosis to be started.
In a specific implementation scenario, after receiving the remote diagnosis operation notification, the device to be maintained reads the content of the remote diagnosis operation notification. In this implementation scenario, the remote diagnostic operation notification includes a first key, which is received and stored by the device to be maintained. The first key is used for assisting the device to be maintained in judging whether other connected devices are authorized devices defined by the user terminal in advance. In other implementation scenarios, the first key may be pre-stored in the device to be maintained.
In another specific implementation scenario, a plurality of keys are stored in the device to be maintained, and each key corresponds to a different authorized device, the remote diagnosis operation notification includes a signaling (for example, including a specific identifier of the first key) specifying the first key, and the device to be maintained calls the corresponding first key after receiving the signaling.
In other implementation scenarios, after receiving the remote diagnosis operation notification, the device to be maintained may also perform a preparation for remote fault diagnosis, such as stopping a currently processed task, and/or confirming whether a communication function is normal, and/or adjusting a communication circuit to a state to be received.
In this implementation scenario, the device to be maintained may further receive a second key sent by the operation and maintenance center device, determine whether the first key and the second key match, and allow the remote diagnosis to be started if the first key and the second key match. In the implementation scenario, whether the first key and the second key are matched is judged through arithmetic operation, and in other implementation scenarios, whether the first key and the second key are matched can be judged through whether the first key and the second key have the same identifier.

In a specific implementation scenario, after receiving a remote diagnosis operation request and a first key, an operation and maintenance center device starts remote diagnosis in response to the remote diagnosis operation request, and sends the first key to a device to be maintained, so that the device to be maintained determines whether to allow starting of remote diagnosis according to the first key.
In this implementation scenario, when a user perceives that the device to be maintained is abnormal in operation, the user starts a client application on the user terminal, and sends a remote diagnosis operation notification to the device to be maintained, where the remote diagnosis operation notification includes a second key, and the device to be maintained receives and stores the second key. In other implementation scenarios, the device to be maintained has the second key stored in advance.
And the equipment to be maintained judges whether the first key and the second key are matched, and if so, the equipment is allowed to start remote diagnosis. In the implementation scenario, whether the first key and the second key are matched is judged through arithmetic operation, and in other implementation scenarios, whether the first key and the second key are matched can be judged through whether the first key and the second key have the same identifier.
S203: and when receiving a notice that the equipment to be maintained allows starting remote diagnosis, sending a remote diagnosis operation instruction to the equipment to be maintained, so that the equipment to be maintained performs remote diagnosis operation according to the remote diagnosis operation instruction.

And after receiving the notice allowing the remote diagnosis to be started, the operation and maintenance center equipment sends a remote diagnosis operation instruction to the equipment to be maintained, so that the equipment to be maintained performs remote diagnosis operation according to the remote diagnosis operation instruction. In other implementation scenarios, the device to be maintained may not send a notification to the operation and maintenance center device, but may choose to accept or reject after the operation and maintenance center device sends the remote diagnosis operation instruction.
In order to ensure the security of remote diagnosis and prevent a maintenance person from damaging a system in a device to be maintained by operating an operation and maintenance center device or obtaining user privacy information in the device to be maintained, in this implementation scenario, the device to be maintained may determine whether a remote diagnosis operation instruction sent by the operation and maintenance center device exceeds a preset authority range (for example, some data is preset as private data or some operation is preset as prohibited operation), and if the remote diagnosis operation instruction does not exceed the preset authority range, the device to be maintained may perform remote diagnosis operation according to the remote diagnosis operation instruction.
In another specific implementation scenario, if the device to be maintained determines that the remote diagnosis operation instruction exceeds the preset authority range, the device to be maintained refuses to perform the remote diagnosis operation according to the remote diagnosis operation instruction, and in other implementation scenarios, the device to be maintained refuses to perform the remote diagnosis operation according to the remote diagnosis operation instruction, and sends alarm information to the user terminal and/or the operation and maintenance center device. And after receiving the alarm information, the operation and maintenance center equipment immediately stops the remote diagnosis operation, and records and reports the exceeding remote diagnosis operation instruction and/or the ID of the corresponding maintenance personnel.
In the implementation scenario, after the device to be maintained performs the remote diagnosis operation according to the remote diagnosis operation instruction, the operation and maintenance center device receives the result of the remote diagnosis operation sent by the device to be maintained, and the maintenance personnel can remotely know the fault phenomenon and reason of the device to be maintained through the result of the remote diagnosis operation and inform the user of performing simple preliminary processing according to the phenomenon and reason.
In another specific implementation scenario, the operation and maintenance device has the highest priority, and may stop the remote diagnosis operation at any time, and when the device to be maintained receives a remote diagnosis operation stop instruction sent by the operation and maintenance center device during the remote diagnosis operation, the remote diagnosis operation is stopped. In other implementation scenarios, the user terminal has the highest priority, and when the device to be maintained receives a remote diagnosis operation stop instruction sent by the user terminal during remote diagnosis operation, the remote diagnosis operation is stopped.
