Embodiment one

Please refer to Figure 1 and Figure 2, Figure 1 is a schematic structural diagram of a WCF-based intranet data display system provided by an embodiment of the present invention, and Figure 2 is another WCF-based intranet data display system provided by an embodiment of the present invention Schematic diagram of the structure of the data display system.

Windows Communication Foundation (WCF) is a series of application frameworks supporting data communication developed by Microsoft, which is a part of the .NET framework. WCF technology has the following advantages: a) Multiple communication protocols. WCF supports a variety of technical protocols, which not only meets the current needs, but also reserves space for subsequent expansion. Although WCF is developed in C# language, it supports communication with software developed in various other languages (such as C language), and can deserialize objects more conveniently. b) Object transfer. Based on the WCF protocol, the sending and receiving ends can transmit objects, which provides greater convenience for programming, and can be easily serialized and deserialized. c) Various clients. Since WCF supports more communication protocols, it can not only provide data to the Web publishing server, but also communicate with other applications in the background to obtain data. d) Push technology. WCF technology supports push technology, that is, the server can automatically send received data to the client without the need for the client to continuously apply (pull data). This feature allows the terminal's request to be forwarded and pushed to the data processing end. e) Cascading. WCF can be expanded well, and new data services can be added and cascaded with existing services to provide convenience for subsequent more complex system configurations. Therefore, the internal and external network data display system of this embodiment is designed based on WCF technology.

The WCF technology-based internal and external network data display system includes a data service center and several web publishing service software.

The data service center is deployed in the intranet to read the back-end data according to the page data application and integrate and process the back-end data to form the front-end data.

The data service center is a service software, developed based on WCF technology, which can respond to the application of the remote end, transmit data to the remote end based on the http protocol, and realize the functions of remote calling and local data integration.

In this embodiment, the data service center mainly transmits data to the WCF publishing server in JSON format. The functions of the data service center mainly include: 1) WCF service. 2) The remote call interface provides a unified data service interface to the outside world. 3) Interface response processing, the data service center determines the data source and data range accessed through the access interface and interface parameters, and returns the data to the applicant after processing. 4) Local data cache processing, the data service center is deployed on the intranet, and the data source can be all the data that needs to be displayed in the intranet: real-time data, historical data; data saved in the form of files, or a database The record in; can be on one server, also can be on multiple servers; In this embodiment, the data service center mainly caches the real-time data.

Please refer to FIG. 3 . FIG. 3 is a schematic diagram of a software architecture of a data service center provided by an embodiment of the present invention. Based on the above functions of the data service center, the data service center includes: a remote call interface, interface routing and data processing modules.

The remote call interface is connected with the web publishing service software, and is used to obtain the page data application sent by the web publishing service software, and transmit the front-end data to the web publishing service software at the same time.

Specifically, the design of the remote call interface conforms to the WCF interface design specification, and is designed according to the requirements of remote call, mainly to complete the front-end and back-end information transmission requirements, that is, to receive the page data application sent by the web publishing service software, and to transmit the front-end data to the web publishing service software.

The number of remote call interfaces is set according to actual needs, and the number can be one or more. In a specific embodiment, there is one interface for remote calling: public virtual string DataProcessForJson(string strsql), where strsql is a character string, representing an interface parameter, which is a combination of multiple parameters, and commas are used between multiple parameters separated, so strsql can contain all the meanings that need to be expressed; for example, "pdop, dt1, dt2" is a string at the software level, but it can be decomposed into: the pdop value between dt1~dt2 is three parameters, but "pdop, dt1, dt2" are not limited to the above meanings, and can be agreed upon according to actual needs.

After receiving the page data application, the remote call interface identifies the corresponding interface parameters to access the corresponding data source information.

The interface routing is connected with the remote call interface, which is used to determine the data source and data range accessed according to the interface parameters corresponding to the page data application, and return the front-end data at the same time.

Specifically, the interface parameters include information on the data source to be accessed, and the interface routing determines the data source and data range to be accessed according to the content of the remote call interface, that is, the interface parameters, and calls the actual data processing module.

In this embodiment, the data source can be all the data that needs to be displayed in the intranet: it can be real-time data, historical data; it can be data saved in the form of a file, or it can be a record in a database; it can be on a server , also on multiple servers.

In a specific embodiment, the data source includes but not limited to real-time status data, data in a database, and file data in a large database. The data range can be one or more of the above data sources, that is, one page data application can apply for one type of data, and one page data application can also apply for multiple types of data, forming a combination of various situations. Specifically, if the page data application is a database application, the interface routing will call the database module; if the page data application is a real-time data application, the interface routing will call the data in the data cache; if the page data application is a file data application, the interface routing will call data; when the page data application includes at least two of real-time data application, database application, and file data application, the interface routing calls at least two corresponding modules. For example, when applying for an index value of a satellite, the index value corresponds to multiple types of data, the satellite information is obtained from the data cache, and the index file information is obtained from the big data, and the index display content is formed after processing.

The data processing module is connected with the interface routing, and is used to obtain back-end data according to the data source and data range and integrate and process the back-end data to form front-end data. That is to say, the data processing module reads and processes the back-end data to form the data required by the front-end.

The database processing module accesses the database through the database access module to extract the corresponding data, and the database data processing module processes it to form the first A front-end data, and transmit these data to the router.

The big data processing module is used to acquire file data from the big database and process the file data to form the second front-end data.

Specifically, the big data processing module includes a big data access module and a file data processing module, wherein the big data access module is connected with the big data storage platform and the file data processing module, and the file data processing module is connected with the interface routing. The big data access module is used to access the big data storage platform and obtain files. The file data processing module extracts the content of the obtained files to form the second front-end data. The second front-end data is the format data required by the front-end, and these format data transmitted to the router.

The real-time data processing module is used to acquire real-time status data and process the real-time status data to form third front-end data.

Specifically, the real-time data processing module includes a real-time data receiving module and a data cache module, wherein the real-time data receiving module is connected to the satellite data processing software and the data cache module, and the data cache module is connected to the interface router. The real-time status data is the data cached in the data cache of the data service center, which contains some commonly used data and real-time updated data; for example, in a certain software, the cached data includes: satellite information, site information and site connection status, satellite Real-time location, etc. Among them, satellite information and site information are commonly used information at the front end, site connection status and satellite real-time position are real-time information, which require the latest data; the real-time data receiving module receives the latest data, and the data cache module caches these latest data Get up and transmit the third front-end data to the interface router as needed. The real-time data processing module caches the latest data, which can improve the response speed of front-end applications.

Further, when the page data application contains one type of data, one set of data in the first front-end data, the second front-end data, and the third front-end data forms the front-end data; when the page data application contains multiple types of data, the first front-end data Multiple sets 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 routing and the front-end data returned by the remote call interface are also strings, which can be returned by means of Json expressions, so that more complex objects can be returned.

Please refer to FIG. 4 , which is a schematic diagram of a processing flow of a data service center provided by an embodiment of the present invention. The processing flow includes steps: S1. The page data application calls the remote call interface, and the remote call interface identifies a corresponding interface parameter string, thereby obtaining the parameter string strsql. S2. The interface routing parses the parameter string strsql to identify the required data. S3. The data processing module identifies the required data according to the parsed character string array, and identifies the back-end data. S4. The data processing module integrates and processes the identified back-end data to form front-end data, and the front-end data is a character string expressed by Json expression. S5, interface routing and remote call interface return Json string.
