S1, obtaining a message to be transmitted, wherein the data format of the message to be transmitted is a text format, the message header of the message to be transmitted stores the current session type, and the data part of the message to be transmitted stores session information corresponding to the current session type; when the method is applied specifically, the message to be transmitted is defined as a text format, and the data structure is session type + content; therefore, when in actual use, a user can set the session type in the message header and the session information in the data part of the message to be transmitted according to different task scenes, so that the flexible application is facilitated; meanwhile, the example session type may be, but not limited to, a task type of the session, if a fault report needs to be performed, the session type is a fault type, and the session information is specific fault and equipment information (such as equipment code (deviceCode), error information array (faultInfo) and the like) that need to be uploaded; of course, under different tasks, the content contained in the header and the data portion of the message to be transmitted is modified correspondingly by the user, and the principle thereof is not repeated; furthermore, after defining the data structure of the text format, in practical application, the user only needs to upload the corresponding task type and data, and the transmitting end can generate the text format message to be transmitted including the session type and the session information.
After obtaining a message to be transmitted in a text format, the data transmission can be directly carried out in the text format; the data transmission process may be, but not limited to, as shown in the following step S2.
S2, transmitting the message to be transmitted to a receiving end by adopting a text communication mode so as to finish data transmission of the message to be transmitted in an isolated network environment; in a specific application, the foregoing transmission process of the message to be transmitted may be, but is not limited to, the following steps S21 to S24.
S21, a transmission service channel between the receiving end and the receiving end is established, and after the transmission service channel is established, a connection request is sent to the receiving end, so that the receiving end responds to the connection request after receiving the connection request, and communication connection is established between the receiving end and the sending end; in this embodiment, the transmission service channel is established by opening the connection between the inside and the outside of the isolation device (under the isolation network, the sending end and the receiving end are isolated by the isolation device) so as to provide a transmission channel for the subsequent data transmission; meanwhile, after the transmission service channel is established, connection between the transmission service channel and the transmission service channel can be established, so that after the communication connection between the transmitting and receiving parties is established, the transmission of the message to be transmitted is completed; the transmission process is as follows in steps S22 to S24.
S22, judging whether the message to be transmitted meets preset requirements, wherein the preset requirements comprise format requirements and structure requirements; in this embodiment, since text data is adopted for transmission, verification of a message to be transmitted is required before transmission, where the verification is to verify whether the data format of the message to be transmitted is a text format, and verify whether the data structure of the message to be transmitted is a session type+a data structure of session information (of course, the session type and the storage location of the session information also need to be confirmed); through the design, the data used by the data transceiver can be ensured to be text data, so that the analysis efficiency in transmission is improved.
After the data verification of the message to be transmitted is completed, the encoding process may be entered, where the encoding process is as follows in step S23.
S23, if yes, coding the message to be transmitted to obtain coded data; in this embodiment, for example, but not limited to, a Base64 coding algorithm is used to complete coding of the message to be transmitted, so as to obtain coded data; thus, the data is encoded, and the completeness and safety of data transmission can be ensured; after the data encoding is completed, the data transmission may be performed as shown in step S24 below.
S24, transmitting the encoded data to the receiving end through the transmission service channel, so that the receiving end decodes the encoded data after receiving the encoded data, and performs data verification on the decoded data, so as to store the decoded data after verification is passed; in this embodiment, since the data transmission is performed in a text format, the receiving end only needs to decode the encoded data after receiving the encoded data, so as to restore the original data; compared with the prior art, the decoded data are not binary data, and conversion of the binary data is not needed, so that the analysis efficiency in data transmission can be improved; meanwhile, the message header stores the session type, so that the receiving end can rapidly determine the type of the session only by analyzing the message header, and accordingly, a corresponding processing scheme is called to process the session, and the session processing speed can be improved.
Furthermore, in this embodiment, after the encoding of the packet is completed, data compression may be performed, that is, the encoded data is subjected to data compression, so as to obtain compressed data; then, the compressed data can be transmitted to the receiving end through the transmission service channel; therefore, the bandwidth occupation and the resource consumption of the data in the transmission process can be reduced; alternatively, compression of the encoded data may be achieved, for example, but not limited to, using an integrated snap algorithm; of course, other compression algorithms may be used, and are not limited to the foregoing examples herein.
In addition, after the encoded data is transmitted to the receiving end, the present embodiment is further provided with a resource release step, and the process thereof may be, but is not limited to, as shown in the following steps S25 and S26.
S25, receiving response information sent by a receiving end is obtained, wherein the receiving response information is generated after the receiving end decodes the coded data, verifies the decoded data and passes the verification; in this embodiment, the receiving end verifies the decoded data, which may include, but is not limited to, verification of integrity; after the integrity verification is passed, the data transmission can be judged to be completed, and at the moment, receiving response information can be generated; then, the resource is released by sending the resource to the sending end, so that the sending end is disconnected with the receiving end; alternatively, the foregoing process may be, but is not limited to, as shown in step S26 below.
S26, closing the transmission service channel based on the receiving response information, and disconnecting the communication connection with the receiving end; in this embodiment, after the transmission is completed, the transmission service channel is closed, and the two sides are disconnected, so that the resources can be released, thereby reducing the resource consumption.
The invention adopts text information to transmit data and defines text data as the data structure of session type and content through the data transmission method in the isolated network environment described in detail in the steps S1-S2 and the sub-steps; based on the method, the data conversion flow during data analysis in the traditional technology can be avoided, the analysis efficiency can be improved, and meanwhile, the data structure can be customized according to the task type, so that different task demands can be met, and the use flexibility is ensured; therefore, the method is very suitable for large-scale application and popularization in the field of data transmission.
In one possible design, the second aspect of the present embodiment is further optimized based on the first aspect of the embodiment, that is, the transmission identifier is stored in the header of the message to be transmitted, so as to complete synchronous communication between the sending end and the receiving end; of course, the accurate procedure of the synchronous communication is before the message to be transmitted is sent, where the synchronous communication procedure may be, but is not limited to, as shown in the following step one and step two.
Step one: sharing the transmission identifier to the receiving end, so that the receiving end feeds back session response information to the sending end after receiving the transmission identifier, wherein the session response information comprises the transmission identifier received by the receiving end; in this embodiment, the sharing process of the transmission identifier may be, but is not limited to,: the transmitting end firstly generates a session request based on the transmission identification, and enters a waiting state of synchronous blocking after the session request is generated; and then, sending the session request to the receiving end, so that the receiving end analyzes the session request after receiving the session request to obtain a transmission identifier transmitted by the sending end, and generating session response information based on the received transmission identifier.
After the session response information fed back by the receiving end is obtained, the receiving end and the session response information can carry out synchronous communication, wherein the establishment process of the synchronous communication can be but is not limited to the following step two.
Step two: receiving session response information sent by the receiving end, and establishing a communication synchronous session with the receiving end based on the session response information so as to realize synchronous sending and receiving of the message to be transmitted; when the method is applied specifically, the transmitting end judges whether the transmission identifier in the session response information is the same as the transmission identifier in the message to be transmitted; if yes, jumping out of the waiting state of synchronous blocking, and transmitting the message to be transmitted to the receiving end in a text communication mode; of course, if the transmission identifiers of the two are different, the waiting state of synchronous blocking is maintained.
Furthermore, in this embodiment, the aforementioned step S21 is also required to be performed before the synchronous communication is established, so as to establish the transmission service channel and the communication connection between the transmitting end and the receiving end; then, after the synchronous communication is established based on the first step and the second step, the transmission of the message to be transmitted can be completed by adopting the steps S22 to S24, and the principle thereof is not repeated.
By the design, the unique transmission identifier is introduced into the session, so that under the framework of asynchronous communication, the receiving parties can realize synchronous communication according to the transmission identifier; based on the method, the device and the system, the service requirements can be met in the scene of synchronous operation.
In addition, the embodiment also supports a message transmission mode of target subscription and release, that is, the sending end transmits the message to be transmitted to the target terminal by using the message transmission mode of target subscription and release; when the method is applied specifically, the target terminal is a terminal subscribed with a catalog of the session type corresponding to the message to be transmitted; in this way, the foregoing manner may be utilized to allow information to be circulated between different networks without requiring direct communication.
In this embodiment, the message delivery manner of the target subscription and release belongs to a communication protocol similar to a message queue, and the difference between the message delivery manner and the traditional communication protocol MQTT is that: the method adopts a directory-based mode to realize a publish-subscribe mode, and the protocol is particularly suitable for the scene of message intercommunication among a plurality of partitions in the power industry and the like, and the design of the protocol allows information to circulate among different networks without direct communication, so that the communication efficiency is improved, and the safety and reliability of communication are ensured.
Meanwhile, in the communication mode, the catalogs often exist in pairs, and the design allows two communication parties to realize communication between the two parties through subscribing and publishing the corresponding catalogs; specifically, when one party issues information to the catalog, the other party can receive the information by subscribing a sister catalog of the catalog, and the process is completed through the cooperation of the isolating device, so that the reliability of text transmission can be ensured; therefore, as long as the corresponding target is configured at the transmitting end and the corresponding catalogue is subscribed at the receiving end, the message can be rapidly transmitted to the terminal subscribed to the catalogue when the message is transmitted at the transmitting end, and therefore the data transmission requirement among a plurality of isolated networks is met.
Through the design, the invention can meet the service requirement under the synchronous operation scene, and can complete the efficient circulation of information among different networks by utilizing the message transmission mode of the standard subscription release; thus, the flexibility of use is further improved.
