The specific implementation of each step of the embodiment shown in fig. 2 is explained in detail below:
in step S210, the smart device establishes websocket communication with the online platform.
In an embodiment of the present disclosure, before the smart device in this step establishes websocket communication with the online platform, the method further includes:
the intelligent device establishes communication with the server through a wireless network and sends the IP address of the intelligent device to the server, for example, in this embodiment, the intelligent device may be automatically connected to a WiFi network and connected to the server based on the WiFi network.
Fig. 3 is a flowchart of an embodiment of the disclosure before step S210 in fig. 2, and as shown in fig. 3, the method specifically includes the following steps:
in step S301, the smart device connects to a wireless network, and runs a preset smart device API (i.e., API) on the smart deviceR). An Application Programming Interface (API for short) is automatically run by the intelligent device, so that the terminal device or the server and the like can directly send instructions to the intelligent device, and the intelligent device is based on the APIRCommands or program files may be received.
In step S302, the server API (i.e. API) running on the server is connected through the smart device APIS)。
In step S303, the intelligent device API sends the IP address of the intelligent device to the server API.
Fig. 4 is a flowchart illustrating step S210 in fig. 2 according to an embodiment of the disclosure, and as shown in fig. 4, the method specifically includes the following steps:
in step S401, the online platform establishes communication with the server through the internet. After the intelligent device is connected to the server in the steps, the intelligent device can log in an online platform by opening a web browser on the terminal device, so that the intelligent device can be connected to the server-side API (namely API)S) I.e. to establish communication between the terminal device and the server.
In step S402, the online platform is connected to the server API, and receives the IP address of the intelligent device through the server API, that is, the online platform can obtain the IP address of the intelligent device in the local WiFi network through communication with the server.
In step S403, the online platform establishes a communication connection with the smart device through the websocket based on the IP address of the smart device.
Based on the steps, the IP address of the intelligent device can be obtained through communication between the server and the terminal device and communication between the server and the intelligent terminal, and therefore websocket communication between the terminal device and the intelligent device is established. The websocket is a duplex communication protocol newly added to html5, and two ends of websocket communication can perform two-way communication between a browser (i.e., an online platform) of a user and an SSH server running on a smart device through an API. The user can send commands and program files to the SSH server without polling the server. Through the websocket communication, a plurality of users can be connected to the same intelligent device, and can communicate through the API and obtain responses immediately.
The online platform in this embodiment runs on a terminal device (e.g., a computer), and provides a programming environment and a visualization environment for a user through the online platform, where the programming environment may be used for the user to write code, and may be specifically implemented by a program programmer, and a completely written program is created and written in the form of the program programmer provided based on the online platform. The online platform may be connected to a server via the internet, or may be connected to a smart device (e.g., a robot) via a local wireless network.
In an embodiment of the present disclosure, a program is created on the online platform through an editor, and the program file is obtained; further, the program file is sent to the server and stored in the server. By saving the completely written program file to the server, the online platform automatically loads the program saved in the server after the user logs in the online platform next time. And the program files stored in the server can be retrieved through the online platform, so that the program files which are written and stored before can be directly called, and the repeated work is reduced.
In an embodiment of the present disclosure, a certain permission may also be set for the online platform to retrieve and view the program file stored in the server as needed, which is convenient for security management. In addition, because the server can communicate with the intelligent device through the websocket, the intelligent device can call the required program file from the server at any time so as to run the program file on the intelligent device.
In step S220, the API of the smart device starts the SSH server on the smart device, and the API of the smart device receives the command and the program file sent by the online platform.
Fig. 5 is a flowchart of step S220 in fig. 2 according to an embodiment of the disclosure, and as shown in fig. 5, the method specifically includes the following steps:
in step S501, an SSH server is started based on the smart device side API.
In one embodiment of the present disclosure, the API (i.e., API) is run on the smart device by running the smart device side API on the smart deviceR) By running APIsRThe SSH server is started. SSH is an abbreviation of security protocol (Secure Shell) built on the application layer basis, which is currently a more reliable protocol dedicated to security for telnet sessions and other network services. The SSH protocol can effectively prevent the problem of information leakage in the remote management process. SSH, when used correctly, can remedy vulnerabilities in the network. SSH clients are adaptable to a variety of platforms, and almost all UNIX platforms-including HP-UX, Linux, AIX, Solaris, Digital UNIX, Irix, and others-can run SSH.
SSH is a remote connection tool, and the connection principle is as follows: the SSH service is a daemon process (demon), the background of the system monitors the connection of the client, the process name of the SSH service is SSHD, and the SSH service is responsible for monitoring the request (generally, an IP 22 port) of the client in real time, and includes information such as exchange of public keys and the like.
In step S502, a command and a program file sent by the online platform are received through the API of the smart device.
In step S503, the API of the smart device saves the program file to the file system of the smart device.
In step S504, the API of the smart device forwards the command to the SSH server on the smart device.
The commands and the program files sent by the online platform can be obtained by creating a program on the online platform through an editor, editing the commands on the online platform through a virtual terminal, and then sending the commands and the program files to the intelligent device side API by the online platform. Wherein the online platform can send commands to the smart device based on the terminal simulator Xterm and SSH2 protocols. SSH2 adds a Diffe _ Hellman mechanism to confirm the correctness of the connection, and the Server checks the correctness of the data source every time the data is transmitted, so as to avoid the invasion of hackers. SSH2 supports RSA, an acronym for Digital Signature Algorithm, and DSA keys, which RSA can both digitally sign and encrypt. The command refers to a shortcut instruction of the computer, such as: gpedit. msc-group policy; sndrec 32-recorder; nshookup-IP address detector; explor-opens a resource manager; logoff-logoff command; tsshutdn- -60 second countdown shutdown command; msc — native user and group; service. msc — local service setting; oobe/msoobe/a- -check if XP is active, etc.
The intelligent equipment receives the command and the program file sent by the terminal equipment through the websocket communication and sends the command and the program file to the APIRAfter receiving the program file, the intelligent terminal stores the program file in the file system of the intelligent device, so that the stored program file can be executed and operated according to the command after receiving the command subsequently.
It should be further noted that, when there are multiple users, the multiple users may communicate with the same intelligent device on the online platforms of multiple different terminal devices at the same time by using the same access terminal IP address, store/retrieve the program file on the intelligent device, and control the intelligent device to operate the program file by sending a command to the intelligent device. Since each intelligent device has a specific IP (the IP is the IP address of the local network), multiple users are allowed to simultaneously access the same intelligent device by using the same access terminal IP, and program files sent by different users are stored in separate folders corresponding to the users in the intelligent device and are dedicated to the specific users. For example, the user A, B, C may log in the online platform, send an instruction and a program file to the smart device, and store the three folders for the three users at the smart device end, so that the corresponding program file may be called by the user to run when the smart device is used.
In an embodiment of the present disclosure, when a plurality of users log on the online platform on different terminal devices, the intelligent device may store the program files sent by the plurality of terminal devices one by one or all at once, and may make corresponding adjustments according to usage scenarios.
In step S230, the program file is executed according to the command, and an execution result is generated.
In an embodiment of the present disclosure, the API forwards the command to the SSH server, and runs the command in the SSH server. For the intelligent device, after receiving the command through websocket communication, the program file stored in the SSH server on the intelligent device can be run according to the command, so that in this step, the online platform can establish websocket communication with the intelligent device, so as to execute the command and the program file, and control the intelligent device. Because the local WiFi network sends commands and program files to the intelligent equipment at high speed, a user can seamlessly wirelessly interact with the intelligent equipment, high-speed real-time programming can be realized, and the program files sent by the online platform can be run on the intelligent equipment in real time. For example, when the SSH server stores the program file W, if the user wants to run the program on the smart device, the user needs to send a command Z for executing the program file W to the smart device API, the smart device API sends the command Z to the SSH server, and then the SSH server runs the command Z, thereby executing the program file W.
Because the intelligent equipment can also be provided with information acquisition equipment such as a camera, a temperature sensor, an infrared sensor and the like according to the requirements of a use scene, a command received by the intelligent equipment can be hardware such as a directly started camera or a program file is operated, the camera is started to work according to a certain period in the program file, and the camera is closed after working for a certain time. Therefore, the intelligent device can work directly according to the command or work by combining with the stored program file, and the intelligent device can generate a corresponding operation result after operation regardless of the mode.
In step S240, the operation result is fed back to the online platform for displaying on the online platform.
In an embodiment of the present disclosure, the result is fed back by executing the command on the SSH server of the smart device, including feeding back any possible error to the user and the result of the operation of the smart device after the operation according to the command, and by using the websocket, the result is fed back by the APIRThe feedback result can be status information (such as system fault information) of the Ubuntu or ROS system, and the like, and can also be a visual feedback result such as text, image, video, and the like. The form of the operation result received and displayed by the online platform therefore includes at least one of text, picture or video.
In the step, the API of the intelligent device stores the program file sent by the online platform in a file system of the intelligent device, and after receiving the command sent by the online platform, the API operates the program file stored in the intelligent device according to the command. For example, a camera or a temperature sensor and other sensors are installed on the intelligent device, the intelligent device runs a program file according to a command, the operation corresponding to the program file is to open the camera for shooting, at this time, correspondingly, the intelligent device executes the running result of the program file according to the command, namely, a video or a picture shot by the camera, and the video or the picture is stored in the intelligent device; and then the intelligent equipment sends the operation result to an online platform through websocket communication, and the online platform carries out visual display on the operation result, namely, the operation result is displayed as a shot video or picture. For example, the operation corresponding to the program file is to acquire the ambient temperature based on a temperature sensor, and at this time, correspondingly, the intelligent device executes the operation result of the program file according to the command, namely the temperature data, and the temperature data is stored in the intelligent device in a text form; and then the intelligent device end API sends the operation result to an online platform through websocket communication, and the online platform displays the operation result in a visual mode, namely the operation result is the temperature data in a text form.
Based on the foregoing, the online platform in this step may also obtain a visual feedback result from the execution of the commands and programs, and visually display the result for the user to view in real time.

Step S604, the online platform running on the user computer opens the API with the robot through the websocket by using the IP address of the robot through the local WiFi networkRThe connection of (2).
Step S605, API run on robotRAn SSH server is started on the robot so that the robot can receive commands in a format compatible with the SSH protocol, which commands can be used in the terminal.
Step S606, terminal on line platform, user inserts and executes command based on Xterm and SSH2 under programming environment.
In step S607, the command and its execution instruction are transmitted locally (on the local network), and transmitted from the online platform on the user' S computer to the API through the websocketRAnd transferred from the online platform to the machine operating on the sameOn the human SSH server, thereby letting the robot execute commands.
In step S608, the robot executes the results of the command on the SSH server, including feedback to the user of any possible errors. Based on websocket communication, by APIRTransmitted to the online platform of the user's computer and displayed on the terminal of the online platform.
In the method, a program can be created based on an editor on an online platform and sent to an API on a serverSAnd thus the program file is saved at the server. And based on the online platform, the presentation file can also be sent to the API running on the robotRUnder a special folder dedicated to a particular user in the robot file system. The robot can run the program in the program file according to the command by using the command on the terminal in real time.
Step S609, the feedback result of the robot for the program file, such as text, image or video, is received based on the online platform, and may be transmitted to the online platform running on the user computer through the local network, and displayed on the terminal device. The method can be realized based on a data transmission and control system consisting of an online platform, a server and a robot.
For example, on the terminal device, the user may view the visual feedback result by clicking a corresponding button on the interface, and if there is no visual feedback result such as text, image, or video, the feedback is null. Therefore, no matter the result is a visual feedback result or an empty result, the user can check the result on the visual interface of the terminal equipment, and the program running result is obtained in real time according to the feedback result of the visual robot. The method can be realized based on a data transmission and control system consisting of the terminal equipment, the server and the intelligent equipment which operate the online platform.
