Problems solved by technology

[0002] At present, the status quo of field acquisition equipment in the field of intelligent transportation in China is that there is no common industry standard in the industry, and there are standards of different manufacturers and local standards. The system developer provides enterprise standards for equipment suppliers to modify the interface, figure 1 It is a common data integration method in the transportation field. The existing data exchange process is customized and developed according to the protocol provided by the manufacturer, and customized development must be carried out for each data source. Taking the electronic police data of a certain manufacturer as an example, the front-end The device transmits the pictures to the central system through FTP (File Transfer Protocol), and transmits the information to the center through the Socket protocol. Since the middle needs to pass through the firewall to enter the private network, the pictures can directly pass through the firewall through the default port of FTP, and the information needs to be parsed from the Socket protocol to After accessing the Web service interface in the private network, the XML format is passed in and stored in the central database. At present, there is no simple and easy solution to realize the rapid integration of equipment from different manufacturers, and the collection equipment manufacturers or integration manufacturers have to do a lot of The integration work, including protocol conversion, message body conversion, data verification, data standardization, etc., has caused the software implementation process of the intelligent transportation project to become a process of interface customization development; in addition, for safety reasons, data collected from the field To the central system often has to go through a gatekeeper or firewall, and the data format needs to be converted into a specific protocol before it can be transmitted to the central computer room, which requires an additional protocol conversion process

Embodiment Construction

[0041] Combine below Figure 2-Figure 7 The technical solutions of the present invention are further described through specific implementation methods.

[0042] like figure 2 As shown, a method for realizing data exchange based on data bus technology includes:

[0043] Step a, establishing a data exchange component library based on data bus technology, the data exchange component library is composed of reusable components;

[0044] Step b, when there is data to be exchanged, analyze the interface protocol involved in the data exchange;

[0045] Step c, judging whether the transmission protocol and message format in the interface protocol are existing components in the data exchange component library, if so, then directly enter step d, if not, then develop the transmission protocol and message format as A transmission protocol conversion component and a message format conversion component, and deploying the transmission protocol conversion component and the message format c...

Abstract

The present invention relates to the field of intelligent transportation, in particular to a method and device for realizing data exchange based on data bus technology. The method includes: establishing a data exchange component library based on data bus technology; Analyze the interface protocol; judge whether the transmission protocol and message format in the interface protocol are existing components in the data exchange component library, if not, develop the transmission protocol and message format into a transmission protocol conversion component and a message format conversion component; according to The interface protocol configures the exchange service, publishes the exchange service in the data bus; performs data exchange on the exchange service according to the exchange mechanism, and the design of the reusable component library of the present invention greatly simplifies the integration process of the intelligent transportation project, and the non-programming exchange service configuration reduces It reduces the technical difficulty of system integration, improves the flexibility of the process, and makes it easy to change the data processing process according to business changes.
