wherein, if the service system of the receiving party is similar to the service system of the sending party of the data, the service file structures of the two systems are similar, that is, the service types corresponding to the messages contained in the service files are the same, and the difference is only the difference of the component elements of the messages, at this time, the localized processing is not needed, only the service data is directly sent to the data receiving party, the data receiving party can directly carry out the standardized conversion on the messages in the service data according to the digital dictionary in the block chain public account book, and if the service system of the receiving party is not similar to the service system of the sending party of the data, the service system is a heterogeneous service system, at this time, the service types corresponding to the messages contained in the service files are different, the localized processing is needed, the messages are transmitted after being the standard files, the receiving party of the data can use the received standardized service data after the localized processing, the cross-system service data transmission is not the standardized processing or the localized processing of the service data, and needs to call a local template and a data dictionary, wherein the local template is used for butting the relation between a service file in the local service data and a service file in the standard service data, the difference of the service file layer is processed, the digital dictionary is used for processing the difference of message component elements, the digital dictionary is a common product identified through a block chain network, the digital dictionary on each node is the same, the local service template (standard template) is customized and used for butting the local service file and the standard service file, and the butting templates of different service systems are different;

specifically, the operation mode may be: one or more standard files corresponding to the first service file are found in a local standard template, then a standard message with the same service type as the first message in the first service file is found in the corresponding standard file, and then the constituent elements in the first message are placed on the specific fields in the corresponding standard message;
for example, the first service file corresponds to one or more standard files, such as the first service file includes a purchase request message and a redemption request message, and the standard file puts the messages of the two services in two separate service files;
similarly, the receiver of the data also compiles the standard service data into the corresponding local service data in the same way.
S13, converting each first message into the corresponding standard message according to the mapping relation;
and S14, packaging a plurality of corresponding standard messages according to the service types contained in the standard files to obtain a plurality of first standard files.
