Specifically, the design of the remote call interface accords with the design specification of the WCF interface, and is designed according to the requirement of remote call, so that the information transmission requirements of the front end and the rear end are mainly completed, namely, the page data application sent by the web release service software is received, and the front end data is transmitted to the web release service software.
The number of the remote call interfaces is set according to actual requirements, and the number of the remote call interfaces can be 1 or a plurality of remote call interfaces. In one particular embodiment, the interfaces that supply remote calls are 1: public virtual string DataProcessForJson (strsql), where strsql is a string representing an interface parameter, is a combination of multiple parameters, and is separated by commas, so strsql may contain all meanings that need to be expressed; for example, "pdop, dt1, dt2" is a string at the software level, but can be decomposed into: the pdop value between dt1 and dt2 is three parameters, but "pdop, dt1, dt2" is not limited to the above meaning and can be agreed according to actual demands.
After receiving the page data application, the remote call interface identifies the corresponding interface parameters to access the corresponding data source information.

In one particular embodiment, the data sources include, but are not limited to, real-time status data, data in a database, file data in a large database. The data range may be one or more of the above data sources, i.e. 1 page data application may apply for class 1 data, 1 page data application may apply for multiple classes of data, forming a combination of multiple cases. Specifically, if the page data application is a database application, the interface route calls the database module; the page data application is a real-time data application, and the interface route calls the data in the data cache; the page data application is a file data application, and the interface route calls the data in the large database; when the page data application comprises at least two of the real-time data application, the database application and the file data application, the interface route calls at least two corresponding modules. For example, if a certain index value of the satellite is applied, the index value corresponds to multiple types of data, satellite information is obtained from a data cache, index file information is obtained from big data, and the index file information is processed to form index display contents.
The data processing module is connected with the interface route and is used for acquiring the back-end data according to the data source and the data range and integrating the back-end data to form front-end data.

The real-time data processing module caches the latest data, so that the response speed of the front-end application can be improved.
Further, when the page data application contains 1 type of data, 1 group of data in the first front end data, the second front end data and the third front end data form front end data; when the page data application contains multiple types of data, multiple groups of data in the first front-end data, the second front-end data and the third front-end data jointly form the front-end data.
In this embodiment, the front-end data returned by the interface route and the front-end data returned by the remote call interface are also character strings, and can be returned by means of the Json expression, so that more complex objects can be returned.
