Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
Embodiment 1
Referring to Fig.1-2, a kind of agreement and software implement scheme of real-time messages communication, including network communication protocol, it is described
Network communication protocol includes client and server-side, and the client sends to the server-side and requests, and establishes the client
To the unidirectional message channel of the server-side, by the unidirectional message channel, the client and server-side foundation are double
To message channel.
The network communication protocol be MQ agreement, the MQ agreement be based on the network communication protocol on TCP/IP, and
The characteristics of TCP/IP, is independently of the specific network hardware, may operate in local area network, wide area network, and suitable for internet,
So MQ agreement has standardized upper-layer protocol, the characteristics of a variety of reliable user services can be provided.
The MQ agreement transfer mode is to carry out transmitting based on TCP/IP or be carried out in transmitting using file copy mode
It is any, the transmission diversification of information can be made in this way.
The MQ agreement uses seq unique sequence numbers, and the server-side can guarantee to disappear in this way according to seq verification message
Breath does not repeat to send, it is ensured that the reliability of message.
The MQ agreement supports message duration, and by Message Record in hardware storage device, the purpose designed in this way is
In order to trace history, user is facilitated to trace device history information by query messages history, the MQ agreement is to message
Information is compressed when being stored, the MQ agreement supports tertiary-structure network, inside and outside the forward and reverse synchronous progress of file
Network data is synchronous, effectively improves information ratio.
The MQ agreement supports breakpoint transmission, and MQ agreement supports producer consumer mode, producer consumer mode to make
With simple, it is suitble to use in automation scene；Producer consumer mode biggest advantage is message deposit in buffer area,
When network blocks, the producer in buffer area, restores message deposit to send, so can when consumer reconnects
Can exist under the weak net environment of network congestion also can normal communication between holding equipment, and the message exchange end wherein temporary suspension in one end
It after recovery, is able to maintain message and does not lose, unduplicated recovery is sent, this feature is suitble to MQ in the weak net such as such as field
It is used under environment；Seq is had in MQ message, can guarantee that the message in MQ is ordered into and unduplicated using seq, MQ is also supported
This security feature of forward and reverse file synchronization, in large-scale enterprises mechanism, forward and reverse synchronize file-based is a kind of
Common intranet security mechanism, the mechanism can be real in a manner of file periodic synchronization under internal network and external network isolation
Existing data interaction, mechanism use which, can significantly improve the safety coefficient of internal network.
The identification title in the unidirectional message channel is identified based on the client device type, the client device
Code, the unidirectional message Path Setup moment and the client device send type of message and generate, therefore have uniqueness,
This channel is only that this client is communicated with server-side, MQ protocol communication channel be binary channels unidirectionally send, i.e., server and
Sending and receiving to be unidirectional between client, two one-way pipelines collectively constitute a communication channel.
The two-way news channel is that binary channels is unidirectionally sent, i.e., sending and receiving as list between server and client side
To two one-way pipelines collectively constitute a communication channel.
Embodiment 2
Referring to Fig. 2, MQ is as a kind of agreement, in realization, using onboard servers as the server of a MQ, on vehicle
Unmanned plane and other equipment establish connection by the MQ with onboard servers, and the message of unmanned plane and equipment is transferred to vehicle-mounted clothes
It is engaged in device, onboard servers then pass through MQ and send control instruction to equipment, form a mobile unit and onboard servers with this
Communication network be then using central server as the server-side of MQ, vehicle for the central server of onboard servers and distal end
Server is carried as client and establishes connection to central server, for the environmental restrictions of intranet and extranet, onboard servers and center
Server can also be communicated by file synchronization.
By embodiment 1-2 it is found that MQ agreement is light in the agreement and software implement scheme of real-time messages of the present invention communication
It measures, is simple, being easily achieved, these features keep its scope of application very extensive, especially in some constrained environments.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
