Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The server-based information interaction method and device aim to achieve real-time transmission of sensor data to a transmission target based on the transfer function of the server by respectively establishing information transmission channels between the server and a main control terminal and between the server and the transmission target. The server can also receive a request of the transmission target and request the main control end to send corresponding sensor data, so that the sensor data is sent to the transmission target, and information interaction between the transmission target and the main control end is realized. Compared with the traditional data transmission, the data transmission is slow, the real-time transmission of the data is difficult to realize, in the data transmission process, the connection target can be identified only by establishing a connection relation every time during data transmission, so that the overall data transmission efficiency is reduced, the traditional data transmission mode can only carry out one-way transmission, only the data is transmitted to the transmission target from the main control end, the data returned by the transmission target cannot be obtained, and therefore information interaction cannot be carried out. Based on this, the information interaction method based on the server in the embodiment of the application. The problem that real-time data transmission and information interaction cannot be achieved by the existing data transmission technology is solved.
The first embodiment is as follows:
fig. 1 is a flowchart of a server-based information interaction method according to an embodiment of the present disclosure, where the server-based information interaction method provided in this embodiment may be executed by a server device, and the server device may be implemented in a software and/or hardware manner, and may be a physical entity server or a cloud server. The following description will be given taking a server device as an example of a main body for executing the information interaction method. Referring to fig. 1, the information interaction method specifically includes:
s110, receiving a request instruction for establishing a websocket protocol sent by a main control end, upgrading the HTTP into the websocket protocol, and establishing a first information transmission channel connected with the main control end; the first information transmission channel is a websocket protocol established between the main control end and the server.
Specifically, referring to fig. 2, when the information interaction method according to the embodiment of the present application performs sensor data transmission, a server receives a request instruction for establishing a websocket protocol sent by a main control end, and the server responds to the request instruction and upgrades an HTTP protocol, in which the server is connected to the main control end, to the websocket protocol, so that a first information transmission channel between the main control end and the server is established, that is, the websocket protocol is established between the main control end and the server. The Websocket protocol is a protocol for carrying out full-duplex communication on a single TCP connection, and in the Websocket protocol, a main control end and a server only need to complete one connection establishment request, and persistent connection can be directly established between the main control end and the server for bidirectional data transmission. The acquisition end is connected with the main control end, the acquired sensor data are transmitted to the main control end in real time, the main control end selects a transmission target which is correspondingly transmitted, and the transmission target is generally an equipment end and comprises a PC end, a large screen end, a mobile end and the like.
Specifically, in an embodiment, before the step of receiving a request instruction for establishing a websocket protocol sent by a master control end, upgrading an HTTP protocol to the websocket protocol, and connecting the master control end through an information transmission channel, the method further includes: and monitoring a request instruction sent by the main control end through a socket interface.
For example, before the master controller has not established the websocket protocol with the server, the server socket needs to monitor the connection request of the master controller in real time. The working process of the connection between the main control end and the server is specifically server monitoring; a request of a main control terminal; and (5) connection confirmation. The server monitoring means that the server socket does not locate a specific master control end socket, but is in a state of waiting for connection, and monitors the network state in real time. The master control request refers to a request for connection made by a socket of the master control, and the target to be connected is the socket of the server. For this purpose, the socket of the master must first describe the socket of the server to which it is to connect, indicate the address and port number of the server socket, and then make a connection request to the server socket.
S120, receiving a data transmission instruction and a target confirmation instruction sent by the main control end through the first information transmission channel, obtaining a transmission target according to the target confirmation instruction, and sending a request instruction for establishing a websocket protocol to the transmission target so as to establish a second information transmission channel connected with the transmission target; the second information transmission channel is a websocket protocol established between the server and the transmission target.
Illustratively, the master control end sends a data transmission instruction and a target confirmation instruction to the server through the first information transmission channel, and aims to inform the server, the master control end wants to send sensor data to the target equipment end, and asks the server to build an information transmission channel connected with the target equipment end, and the target equipment end is a transmission target. The data transmission instruction may include sensor data, the master control end directly sends the sensor data to the server, the server sends the sensor data to the target equipment end, or the data transmission instruction may not include the sensor data, and after the server is connected with the target equipment end, the server sends the corresponding sensor data according to the requirements of the target equipment end. The target confirmation instruction comprises address information of the target equipment end, and the server searches and connects the target equipment end according to the address information.
Specifically, referring to fig. 2, the server sends a request instruction for establishing a websocket protocol to the target device, establishes a second information transmission channel based on the websocket protocol, and receives information sent by the target device and sends information to the target device through the second information transmission channel. The general target device end can be a plurality of device ends, and a one-to-one information transmission channel can be established between the server and different target device ends.
Specifically, referring to fig. 3, the second information transmission channel building process includes:
s1201, receiving a data transmission instruction sent by the main control terminal through the first information transmission channel, and analyzing the data transmission instruction;
s1202, receiving a target confirmation instruction sent by the main control end through the first information transmission channel, analyzing the target confirmation instruction to obtain a transmission target selected by the main control end, and acquiring address information of the transmission target according to the transmission target and a preset communication directory;
s1203, according to the address information, sending a request instruction for establishing a websocket protocol to the transmission target, and establishing a second information transmission channel connected with the transmission target.
Illustratively, the server receives and analyzes a data transmission instruction sent by the main control end through the first information transmission channel, so as to know that the main control end needs to send the sensor data to a certain equipment end. Then, the server receives a target confirmation instruction sent by the main control end through the first information transmission channel, and acquires address information (namely, address information of a transmission target) of the target equipment end from the target confirmation instruction, so that which target equipment end the main control end wants to transmit is known. Therefore, the server finds the target equipment side based on the address information, sends a request instruction for establishing the websocket protocol to the target equipment side, and establishes a second information transmission channel based on the websocket protocol between the target equipment side and the server after the target equipment side receives the request for establishing the websocket protocol. And after the server establishes a second information transmission channel connected with the target equipment terminal, if the data transmission instruction is analyzed to obtain sensor data, the sensor data sent by the main control terminal is sent to the target equipment terminal for the target equipment terminal to display the sensor data. In the websocket protocol, the target equipment end and the server only need to complete one connection establishment request, and persistent connection can be directly established between the target equipment end and the server, and bidirectional data transmission is performed, so that no matter the main control end sends a data transmission instruction and a target confirmation instruction to the server end, or the server sends sensor data to the target equipment end, the connection request does not need to be sent to the target equipment end, but information is directly sent through the second information transmission channel and the first information transmission channel, and the data transmission efficiency is improved.
S130, receiving data format information sent by the transmission target through the second information transmission channel, and sending the data format information to the main control end through the first information transmission channel, so that the main control end processes sensor data according to the data format information.
Illustratively, the data transmission instruction sent by the main control end to the server does not include sensor data, the target device end (i.e., the transmission target) sends its own data format information to the server through the second information transmission channel, and after receiving the data format information, the server learns that the target device end is in a mode capable of displaying the sensor data, so that the data format information is sent to the main control end through the first information transmission channel, the main control end is informed that the target device end receives the sensor data constantly, but the sensor data needs to be processed according to the data format information, and the sensor data conforming to the data format of the target device end can be normally displayed by the target device end.
For example, the data transmission instruction sent by the master control end to the server includes sensor data, and with reference to fig. 4, specifically, the information interaction flow includes:
s1301, sending the sensor data obtained through analysis to the transmission target through the second information transmission channel, wherein the transmission target is used for judging whether the data format of the sensor data is consistent with a preset data format; the preset data format is a display data format configured by the transmission target for leaving a factory;
s1302, receiving data format information sent by the transmission target through the second information transmission channel when the data format of the sensor data is inconsistent with a preset data format;
s1303, the data format information is sent to the main control end through the first information transmission channel, so that the main control end processes the sensor data according to the data format information.
For example, when the server sends the sensor data to the target device end through the second information transmission channel, the sensor data cannot be normally displayed because the data format of the sensor data is not matched with the data format that can be displayed at the target device end, and the main control end is required to adjust the sensor data according to the data format information of the target device end. Then, the target device sends its own data format information to the server through the second information transmission channel, the server forwards the data format information, and sends the data format information to the main control end through the first information transmission channel. After receiving the data format information, the main control end learns that the sensor data sent in advance is not in accordance with the data format of the target equipment end, so that the sensor data is found out from the database, and the data format of the sensor data is adjusted according to the data format information. Based on the transfer function of the server, the information interaction between the main control end and the target equipment end is realized.
S140, receiving the processed sensor data sent by the main control end through the first information transmission channel, and sending the sensor data to the transmission target through the second information transmission channel, so that the transmission target displays the sensor data.
For example, the server serves as an information transfer station of the main control end and the device end, and after receiving the sensor data sent by the main control end, the server sends the sensor data to the target device end. Based on the transfer function of the server, the sensor data meeting the requirements of the target equipment terminal in real time is sent to the target equipment terminal.
In summary, by receiving a request instruction for establishing a websocket protocol sent by a main control end, upgrading an HTTP protocol into the websocket protocol, and establishing a first information transmission channel connected to the main control end; receiving a data transmission instruction and a target confirmation instruction sent by the main control end through the first information transmission channel, acquiring a transmission target according to the target confirmation instruction, and sending a request instruction for establishing a websocket protocol to the transmission target, so as to establish a second information transmission channel connected with the transmission target; receiving data format information sent by the transmission target through the second information transmission channel, and sending the data format information to the main control end through the first information transmission channel, so that the main control end processes sensor data according to the data format information; and receiving the processed sensor data sent by the main control end through the first information transmission channel, and sending the sensor data to the transmission target through the second information transmission channel, so that the transmission target displays the sensor data. By adopting the technical means, the sensor data are transmitted to the transmission target in real time by respectively establishing the information transmission channels between the server and the main control terminal and between the server and the transmission target and based on the transfer function of the server. The server can also receive a request of the transmission target and request the main control end to send corresponding sensor data, so that the sensor data is sent to the transmission target, and information interaction between the transmission target and the main control end is realized.
Example two:
on the basis of the first embodiment, fig. 5 is a flowchart of a server-based information interaction method provided in the second embodiment of the present application. Referring to fig. 5, a server-based information interaction method includes:

And S260, sending the target sensor and the data format information to the main control end through the first information transmission channel, wherein the main control end is used for acquiring corresponding sensor data according to the target sensor and processing the sensor data according to the data format information.
S270, acquiring sensor data corresponding to the target sensor sent by the main control end through the first information transmission channel, and sending the sensor data to the transmission target through the second information transmission channel, so that the transmission target displays the sensor data.
For example, after the target device side (i.e., the transmission target) displays the sensor data sent by the main control side, the device side user wants to switch the sensor data, for example, the target device side is playing a monitoring picture of the monitoring device above the tank body explosion field, and the responsible person at the device side wants to obtain a monitoring picture of the monitoring device on the side of the tank body explosion field. And sending a request instruction for switching the sensor data to the server through the target equipment end, wherein the request instruction comprises the target sensor and the data format information requested by the target equipment end. The server receives the request instruction, learns that the target equipment end wants to acquire new sensor data, then sends target sensor and data format information to the main control end through the first information transmission channel, informs the main control end that the target equipment end requests to display the sensor data of the target sensor, and reminds the main control end to remember to process the sensor data according to the data format information. And then the main control end acquires corresponding sensor data from the database according to the target sensor, performs corresponding data format adjustment on the sensor data, sends the sensor data to the server through the first information transmission channel, informs the server that the sensor data requested by the target equipment end is sent, and requests the server to receive and forward the sensor data to the target equipment end. And then the server receives sensor data corresponding to the target sensor and sends the sensor data to the target equipment end through the second information transmission channel, and the target equipment end displays the sensor data on the display screen after receiving the sensor data. The main control end receives the request instruction sent by the equipment end through the server, corresponding data are sent according to the request instruction of the equipment end, the target equipment end does not passively receive information sent by the main control end any more, the target equipment end can put forward self requirements to the main control end, and user experience of the equipment end is improved.
In summary, in the embodiment, the sensor data is sent to the transmission target in real time by establishing the information transmission channels between the server and the main control terminal and between the server and the transmission target respectively and based on the transfer function of the server. The server can also receive a request of the transmission target and request the main control end to send corresponding sensor data, so that the sensor data is sent to the transmission target, and information interaction between the transmission target and the main control end is realized.
