At present, the existing message transmission system mainly includes the following steps that a data interface technology is adopted to realize point-to-point information transmission between systems, and a data bus technology is adopted to realize message transmission based on a bus between systems, wherein the data bus technology is adopted to realize message transmission based on the bus between the systems, and the main process of the system for message transmission is as follows: the unified receiving, route identification and unified sending of the messages to be sent are realized through the message bus. The message source side sends the message by calling the bus service and appoints the destination, the bus judges the routing relation according to the destination of the message, and calls the receiving service of the corresponding message receiver to finish the message distribution. The system can meet the requirements of universality and low cost, but cannot completely meet the requirements of strong controllability, high safety and traceability. Firstly, a message source side cannot be limited, a message transmission direction is pre-designated by a message sending side, message sending time is real-time sending, dynamic adjustment cannot be carried out in the transmission process, and strong controllability requirements cannot be met; secondly, the bus cannot perform desensitization processing on message contents and cannot completely meet the requirement of high safety; finally, the bus only forwards messages, the message body is not reserved, the process records of message receiving, routing and sending are insufficient, sufficient basis cannot be provided for message audit and tracing, and the requirement of traceability cannot be met. Therefore, the existing message transmission system cannot effectively meet the message transmission requirement required by a collaborative scene of a spacecraft development management task.

To facilitate an understanding of the operation of the messaging system described above, the following briefly describes the processes of message registration, message processing, message scheduling, and message transmission by way of example.
Step 1, setting the interface type { I |0 is more than or equal to I and less than or equal to 1, wherein I belongs to Z }, and respectively representing WebService and SMTP from small to large.
And 2, setting an updating mode of the message { M |0 is more than or equal to M and less than or equal to 1, wherein M belongs to Z }, and respectively representing an increment mode and a coverage mode from small to large.
And 3, setting a state value { S |0 is less than or equal to S is less than or equal to 1, wherein S belongs to Z }, 0 represents a new addition, and 1 represents an end.
And step 4, after receiving the message data sent by at least one message source, if at least one message is a backlog with M ═ 0 in the message data, the message receiving module performs structural processing on the at least one message, wherein the structural processing includes setting a message Id, a message type, a message title, a message content, a generation time, and a state S (the value is 0).
Step 5, if at least one message is a message with the value of M ═ 0, the message receiving module performs structural processing on the at least one message, wherein the structural processing comprises setting of a message Id, a message type and a state S (the value is 1); since the state S of the at least one message is 1, that is, it indicates that the at least one message is completed, the message receiving module sends the at least one message to the message registration module, and performs step 8 in the message registration module.
And 6, after the message receiving module carries out structuring processing on the received messages, for any message with the state S of 0, which represents a newly added message, the message receiving module sends the message to the message registering module, and the step 8 is executed in the message registering module.
And 7, if at least one message is M-1, the message receiving module reports all current messages according to a certain period, and the reported message attributes comprise contents such as message Id, message type, message title, message content and generation time.
Step 8, after the message registration module receives the message data sent by the message receiving module through a preset interface, judging the type of the interface for receiving any message data according to the message type in the message data; if I is 0, the message is transmitted to the message MSMQ through the SOAP protocol interface, and if I is 1, the message is transmitted to the MSMQ message queue through the SMTP protocol interface.
And 9, reading the message in the MSMQ queue by the message sending component in the message scheduling module.
And step 10, the message sending module forwards the message in the MSMQ message queue to at least one message receiving end by using an XMPP protocol. Specifically, the IP address information corresponding to the user account of the message receiving end is pushed to each message receiving end.
In the scheme provided in the embodiment of the application, the message data of the message source received by the message receiving module 11 is unregistered message data, and then the unregistered message data is registered by the message registering module 12, that is, the message name, the message source, the message destination and the sending time are added to the message data, that is, the message source does not set the message source, the message destination and the sending time, but the received message data is uniformly registered by the message registering module 12 through a preset message registering policy, so that the controlled management of the contents of the message name, the message source, the message destination and the like is realized, the controllability of message transmission is greatly improved, and the actual requirement of message development required by a spacecraft management task collaborative scene is effectively met.
