Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Lack modularization and consistance in order to solve existing Floating Car disposal system, be unfavorable for the problem of the change and progress of Floating Car disposal system, the embodiment of the invention provides a kind of preprocess method and device of transport information.
As shown in Figure 1, the preprocess method of the transport information that the embodiment of the invention one provides comprises:
Step 101 is converted into the transport information of an above data source data of unified specification.
In the present embodiment, an above data source can comprise Taxi Management System in the step 101, and freight scheduling specialist's information management system can also comprise the third party of secondary road conditions system etc. is provided, and gives unnecessary details no longer one by one at this.Because the form of the transport information of different data sources may be different, and when carrying out data transmission, may adopt different communications protocol, therefore at first need to adopt step 101 transport information of an above data source to be converted into the data of unified specification, the data of this unified specification, can be the data of arbitrary format, give unnecessary details no longer one by one at this.
In the present embodiment, step 101 can use a plurality of threads simultaneously the transport information in different pieces of information source to be handled, and also can use a thread to handle the transport information in different pieces of information source successively, gives unnecessary details no longer one by one at this.
In the present embodiment, step 101 can be converted into the transport information of an above data source data of unified specification by the mode of configuration file, also can the transport information of an above data source be converted into the data of unified specification, give unnecessary details no longer one by one at this by other modes.Wherein, the mode by configuration file can comprise the detailed process that an above data transport information far away is converted into the data of unified specification: at first the characterisitic parameter according to the transport information in different pieces of information source is provided with configuration file; The transport information that is the different pieces of information source according to the kind and the quantity of data source in the configuration file is distributed thread then; Obtain the agreement of the transport information in different pieces of information source; According to this agreement, it is adaptive to use corresponding thread that transport information is carried out, and obtains the data of unified specification.
In the present embodiment, step 101 can transform this transport information when receiving the transport information of an above data source; Also can at first store the transport information of an above data source that receives, when the size of storage satisfies the buffer memory limit, this transport information be transformed, give unnecessary details no longer one by one at this.
Step 102 sends the data of this unified specification to the Floating Car disposal system.
In the present embodiment, step 102 can be used transmission control protocol (Transmission Control Protocol, TCP) mode sends the data of this unified specification to follow-up Floating Car disposal system, also can use other modes to send the data of this unified specification, give unnecessary details no longer one by one at this to the Floating Car disposal system.
The preprocess method of the transport information that the embodiment of the invention provides, be converted into the data of unified specification by transport information with an above data source, and, make the Floating Car disposal system unify to handle to the transport information of an above data source to the transmission of Floating Car disposal system.The technical scheme that the embodiment of the invention provides has solved existing Floating Car disposal system need adopt different reception and disposal route at different floating car data sources, lack modularization and consistance, be unfavorable for the problem of the change and progress of Floating Car disposal system.
