The beneficial effects of the invention are as follows:
and asynchronously transmitting data messages between the hosts by using a windows message queue mechanism, and storing the data messages in a specified folder for an opposite-end system to access. And after receiving the issued data message, the opposite terminal system sends a receiving receipt, and confirms the delivery after being received by the windows service program. The accurate delivery of the message body is ensured, and the disorder caused by the error information transmission is avoided.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments. It will be appreciated by those of skill in the art that the following specific examples or embodiments are a series of presently preferred arrangements of the invention to further explain the principles of the invention, and that such arrangements may be used in conjunction or association with one another, unless it is expressly stated that some or all of the specific examples or embodiments are not in association or association with other examples or embodiments. Meanwhile, the following specific examples or embodiments are only provided as an optimized arrangement mode and are not to be understood as limiting the protection scope of the present invention.
Examples
As shown in fig. 1, an embodiment of the present invention provides a method for transmitting data at a time of a passenger train, where a windows message queue mechanism is used to asynchronously transmit data packets between hosts, and the data packets are stored in a designated folder for an opposite-end system to access.
The detailed principle of the mechanism is as follows:
1) the database generates a message body, a message header and a message queue transmission path formed by a data file through the regular execution of the storage process.
2) The transmitting end writes the message body and the message header into the special message queue through the CLR format storage process.
3) And the sending end reads the message body from the windows special message queue, starts a thread and sends the message body to the opposite end receiving address specified in the service configuration file through a UDP (user datagram protocol) or a TCP/IP (transmission control protocol/internet protocol).
4) After receiving UDP or TCP/IP handshake signals transmitted from the transmitting end, the receiving end receives the data message and stores the data message into a buffer area, and sends a receipt back to the transmitting end.
In this process, for the purpose of facilitating the next transmission or access, for the received message body, it is also necessary to convert to the predefined ASCII or UNICODE message body format of the message queue, start a thread, write the message body to the native dedicated message queue, and the queue path is specified by the service configuration file.
