Method and device for achieving data exchange based on data bus technology

Abstract

The invention relates to the field of intelligent traffic, in particular to a method and a device for achieving data exchange based on a data bus technology. The method comprises the steps that a data exchange component library based on the data bus technology is established; when data is required to be exchanged, an interface protocol relating to data exchange is analyzed; whether a transport protocol and a message format in the interface protocol are components available in the data exchange component library are judged; if not, the transport protocol and the message format are developed into a transport protocol conversion component and a message format conversion component; exchange service configuration is performed according to the interface protocol; an exchange service is released in a data bus; and the data exchange is executed according to an exchange mechanism. According to the method and the device, the reusable component library is designed, so that an integration procedure of an intelligent traffic project is simplified greatly; the technology difficulty of system integration is reduced by the non-programmed exchange service configuration; the flexibility of a flow is improved; and a data processing flow can be changed conveniently and quickly for an operation change.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and device for realizing data exchange based on data bus technology. Background technique [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.

[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
