Detailed Description
For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that the operation and maintenance working state is complex, and in practical application, there are a plurality of limitations of objective factors. When software running on an intelligent terminal fails and operation and maintenance personnel at a premises cannot solve the failure, technical support of remote technical developers is often required. According to the specific practice of remote operation and maintenance, the following application provides a scenario that some target terminals need to perform remote operation and maintenance, but cannot interact with normal transmission of a remote processing terminal:
for example, the target terminal is in an intranet environment, while the remote processing terminal used by the remote technology developer is in an extranet environment. Or the network equipment in the field fails, so that the target terminal cannot be networked. Or the target terminal has access control strategies such as a firewall, etc., so that the target terminal does not allow the external network interface to be opened.
Under the condition that the target terminal needs to perform remote operation and maintenance, the target terminal cannot interact with remote software, cannot send a work log or a configuration file of the current target terminal to a remote technical developer, and cannot directly receive maintenance instructions.
In such a case, in order for the remote technician developer to learn the current work log or configuration file of the target terminal, the local operator typically communicates a message in a spoken manner, and the remote technician instructs the operator to perform configuration modification or correct deployment of software. The interaction mode is easy to generate information asymmetry, so that the communication cost of both parties is increased, and the problem solving speed is reduced.
Referring to fig. 1, in order to solve the technical problem of difficulty in remote operation and maintenance interaction, the present application provides a remote operation and maintenance method. Specifically, the remote operation and maintenance method comprises the following steps:
s110: and recording the screen picture of the target terminal.
S120: and sending the screen picture to a remote processing terminal.
The target terminal refers to an intelligent terminal with a software running problem. The remote processing terminal refers to an intelligent terminal operated by a remote technology developer. And the screen of the target terminal displays the current work log or configuration file of the target terminal.
It will be appreciated that in the case of a target terminal with a high security level, the target terminal is not allowed to interact with the remote software, nor is it allowed to send the current target terminal's work log or configuration file to the remote processing terminal. In order to enable a remote technology developer to know the current work log or configuration file of the target terminal, the most effective notification mode is to send the current screen picture to the remote processing terminal.
For this purpose, an intermediate device is required to record the screen of the target terminal and to transmit the screen to the remote processing terminal. Of course, the intermediate device must have a picture recording function, i.e. a camera.
When the intermediate device records the screen picture of the target terminal, the working environment or surrounding personnel of the target terminal may be recorded, so that privacy leakage is caused. In a specific embodiment provided in the present application, before the screen image is sent to the remote processing terminal in the step, a mask may be further set for the screen image of the non-target terminal, so as to protect the working environment of the target terminal.
Specifically, the screen of the target terminal has graphic features of the terminal screen frame and character features such as a work log or a configuration file. Therefore, the pre-trained neural network algorithm model can be adopted to conduct feature recognition on the recorded screen picture so as to determine the screen picture of the target terminal; and blurring or shielding the screen picture of the non-target terminal, so that the work environment of the target terminal and the privacy information of surrounding personnel of the target terminal are protected.
S130: and receiving a maintenance instruction packet which is generated according to the screen picture and comes from the remote processing terminal.
It will be appreciated that when a remote technology developer using a remote processing terminal receives a screen of a target terminal, a maintenance instruction package may be created for the current work log or configuration file of the target terminal. And then sending the maintenance instruction packet to the intermediate equipment. And the intermediate equipment receives a maintenance instruction packet which is produced according to the screen picture and comes from the remote processing terminal.
S140: and establishing a peripheral transmission connection with a peripheral transmission protocol with the target terminal.
S150: and converting the maintenance instruction packet into a transcoding instruction packet meeting the peripheral transmission protocol.
S160: and enabling the target terminal to acquire the transcoding instruction packet through peripheral connection.
It will be appreciated that, since the target terminal with a higher security level does not allow the external network interface to be opened, i.e. does not allow the maintenance instructions to be received directly, the inventor establishes a peripheral transmission connection with the target terminal to transmit the maintenance instruction packet to the target terminal. The peripheral transmission connection does not belong to an external network interface, but adopts a peripheral interface.
In a specific embodiment provided in the present application, the peripheral transmission connection has a peripheral transmission protocol, and the peripheral transmission protocol defines a peripheral transmission mode. To save development resources, the peripheral transport connection may employ a mature USB transport connection, and the peripheral transport protocol may appear as a USB transport protocol.
Correspondingly, when the peripheral transmission connection has a peripheral transmission protocol, the maintenance instruction packet needs to be converted into a transcoding instruction packet meeting the peripheral transmission protocol. For example, when the peripheral transmission protocol of the present application adopts the USB transmission protocol, the maintenance instruction packet needs to be converted into a USB transcoding instruction packet. The USB transcoding instruction packet comprises a license plate packet, a data sub-packet and a handshake sub-packet. The data sub-packet is a transcoding packet of the maintenance instruction packet; the license plate packet specifies the device address and endpoint of the destination or source of the data sub-packet, thereby ensuring that only one device responds to the data sub-packet/token sub-packet; the handshake sub-packet indicates the success or failure of the transmission. And the target terminal acquires a transcoding instruction packet through peripheral connection so as to complete remote operation and maintenance work.
Further, in a specific embodiment provided in the present application, before the step of receiving the maintenance instruction packet from the remote processing terminal, the operation authority of the remote processing terminal needs to be verified, so as to avoid malicious interference of the remote maintenance work.
Of course, the remote operation and maintenance method can also record the information of the remote technical developer using the remote processing terminal, so as to prevent the remote technical developer from operating wantonly, and also facilitate the later tracing or responsibility division.
Further, in still another specific embodiment provided in the present application, in order to protect the secure transmission of the maintenance instruction packet, the remote processing terminal may further encrypt the maintenance instruction packet by using a preset encryption protocol. Correspondingly, after receiving the encrypted maintenance instruction packet, decrypting the maintenance instruction packet according to a preset encryption protocol to generate a real maintenance instruction packet.
Referring to fig. 2, to support the remote operation and maintenance method, the present application further provides a remote operation and maintenance system 100, including:
a target terminal 11;
a remote processing terminal 12 for transmitting maintenance data packets;
an operation and maintenance device 13 for forwarding the maintenance data packet to the target terminal 11.
The target terminal 11 refers to an intelligent terminal having a software running problem. The remote processing terminal 12 refers to an intelligent terminal operated by a remote technology developer.
It will be appreciated that in case the security level of the target terminal 11 is high, the target terminal 11 is not allowed to interact with remote software, nor is the current log or configuration file of the target terminal 11 sent to the remote processing terminal 12, nor is the target terminal 11 allowed to directly receive maintenance instructions. For this purpose, the inventor uses the operation and maintenance device 13 as a transfer device to realize information interaction between the target terminal 11 and the remote processing terminal 12.
Specifically, the operation and maintenance device 13 specifically includes:
a video recording module 131 for recording a screen of the target terminal 11;
a transmission module 132 for transmitting the screen to the remote processing terminal 12; and is further configured to receive a maintenance instruction packet from the remote processing terminal 12, which is made according to the screen;
an external connection module 133, configured to establish a peripheral transmission connection with the target terminal 11, where the peripheral transmission connection has a peripheral transmission protocol;
the transcoding module 134 is configured to convert the maintenance instruction packet into a transcoding instruction packet that satisfies a peripheral transmission protocol.
It will be appreciated that in order for the remote technology developer to learn the current work log or configuration file of the target terminal 11, the most efficient notification is to send the current screen to the remote processing terminal 12. For this purpose, the operation and maintenance device 13 records the screen of the target terminal 11 through the video recording module 131 and transmits the screen to the remote processing terminal 12 through the transmission module 132. Of course, the video module 131 is represented as a camera in a specific application scenario.
Considering that the recording module 131 records the screen of the target terminal 11, the working environment or surrounding personnel of the target terminal 11 may be recorded, thereby causing privacy leakage. In one embodiment provided herein, the transmission module 132 may also set a mask for the screen of the non-target terminal to protect the working environment of the target terminal 11 before sending the screen to the remote processing terminal 12.
Specifically, the screen of the target terminal 11 has graphic features of the terminal screen frame, and character features such as a work log or a configuration file. The transmission module 132 can perform feature recognition on the recorded screen using a pre-trained neural network algorithm model to determine the screen of the target terminal 11; the screen of the non-target terminal is subjected to fuzzy processing or shielding processing, so that the work environment of the target terminal 11 and the privacy information of surrounding personnel of the target terminal 11 are protected.
When the remote processing terminal 12 receives the screen of the target terminal 11, a remote technology developer using the remote processing terminal 12 can make a maintenance instruction packet for the current work log or configuration file of the target terminal 11. The remote processing terminal 12 then transmits a maintenance instruction packet created from the screen to the operation and maintenance device 13.
The transmission module 132 of the operation and maintenance device 13 then receives the maintenance instruction packet from the remote processing terminal 12, which is made according to the screen.
Considering that the target terminal 11 with a higher security level does not allow an external network interface to be opened, i.e. does not allow a maintenance command to be directly received, the operation and maintenance device 13 establishes a peripheral transmission connection with the target terminal 11 through the external module 133 to transmit the maintenance command packet to the target terminal 11. The peripheral transmission connection does not belong to an external network interface, but adopts a peripheral interface.
In a specific embodiment provided in the present application, the peripheral transmission connection has a peripheral transmission protocol, and the peripheral transmission protocol defines a peripheral transmission mode. To save development resources, the peripheral transport connection may employ a mature USB transport connection, and the peripheral transport protocol may appear as a USB transport protocol. Correspondingly, the external module 133 may be represented as a USB male connector, and the target terminal 11 is provided with a USB female connector matched with the USB male connector, so as to establish a USB transmission connection.
Correspondingly, when the peripheral transmission connection has a peripheral transmission protocol, the external module 133 also needs to convert the maintenance instruction packet into a transcoding instruction packet satisfying the peripheral transmission protocol. For example, when the peripheral transmission protocol of the present application adopts the USB transmission protocol, the external module 133 is required to convert the maintenance instruction packet into a USB transcoding instruction packet. The USB transcoding instruction packet comprises a license plate packet, a data sub-packet and a handshake sub-packet. The data sub-packet is a transcoding packet of the maintenance instruction packet; the license plate packet specifies the device address and endpoint of the destination or source of the data sub-packet, thereby ensuring that only one device responds to the data sub-packet/token sub-packet; the handshake sub-packet indicates the success or failure of the transmission. And the target terminal 11 acquires the transcoding instruction packet through the peripheral connection to complete remote operation and maintenance work.
Further, the keyboard connected with the target terminal 11 can be selectively modified to realize unidirectional input of the keyboard valid signal.
Referring to fig. 3, the present application further provides a modified keyboard 200, where the keyboard 200 includes a main control chip 21, a keyboard key 22, a peripheral transmission interface 23 and a decoding circuit 24. Wherein the main control chip 21 sends key information to the target terminal 11 through a peripheral transmission protocol. The peripheral transmission interface 23 may be represented as a USB interface in a specific application scenario.
Specifically, the modification process of the keyboard 200 is to add a USB interface and decoding circuit 24 to the original keyboard 200. For example, when the external module 133 is a USB male; the keyboard 200 may be provided with a USB female connector that matches the USB male connector. The modified keyboard 200 may receive a maintenance instruction packet from the remote processing terminal 12 through the USB interface, which is made according to the screen. The keyboard 200 may then decode the maintenance instruction packet into a key signal receivable by the main control chip 21 through the decoding circuit 24. Finally, the key signal corresponding to the maintenance instruction packet can be unidirectionally transmitted to the target terminal 11 by the main control chip 21 of the keyboard 200 in the form of an effective key signal, thereby completing remote maintenance.
Of course, if the target terminal 11 is connected to another device, the central control chip may be integrated into the other device.
Further, in one embodiment provided in the present application, the transmission module 132 needs to verify the operation authority of the remote processing terminal 12 before receiving the maintenance instruction packet from the remote processing terminal 12, so as to avoid malicious interference of the remote maintenance work.
Of course, the maintenance instruction packet may also record information about the remote technology developer using the remote processing terminal 12, so as to prevent the remote technology developer from operating wantonly, and also facilitate later tracing or responsibility division.
Or the decoding circuit 24 of the main control chip 21 of the keyboard 200 is physically isolated, so that the main control chip 21 can only obtain legal input signals. And all operations will leave traces for auditing.
Further, in another embodiment provided in the present application, to secure transmission of the maintenance instruction packet, the remote processing terminal 12 may further encrypt the maintenance instruction packet by using a preset encryption protocol. Correspondingly, the operation and maintenance device 13 further includes a decryption module 135, configured to decrypt the maintenance instruction packet according to a preset encryption protocol, to generate a real maintenance instruction packet.
In summary, in the remote operation and maintenance system 100 provided in the present application, the operation and maintenance device 13 sends the screen of the target terminal 11 to the remote processing terminal 12, and forwards the maintenance instruction packet generated according to the screen from the remote processing terminal 12 to the target terminal 11, thereby improving the working efficiency of remote operation and maintenance. The effective input of the maintenance instruction packet is achieved by modifying the keypad 200 of the connection destination terminal. And the security of the remote operation and maintenance working process is improved by the technical means of setting a mask on the screen picture of the non-target terminal, verifying the operation authority of the remote processing terminal 12, encrypting the maintenance instruction packet and the like.
