In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is, the general analyzing and processing method of a kind of traffic data, including following process:
Step 1: generate dynamic link library: according to configuration information, data parsing to be resolved is become the dynamic link library of standard agreement, specifically include following process:
Step 11: according to the uniqueness of transportation industry data, uses predefined XML Schema(extensible markup language) data element of data to be resolved is extended and defines by form；Predefined XML Schema form describes the Property Name of data to be resolved (traffic data key element), protocol type and weave connection relation；
Step 12: definition agreement, this protocol conventions information service ID, ownership unit and service message content；
Step 13: the protocol generation configuration information that will define；Configuration information defines element information and the type of data to be resolved (source transportation industry data), and has arranged and corresponding relation between each element in XML Schema；
Step 14: the configuration information of the data to be resolved of analysis protocol definition, becomes the dynamic link library of standard agreement according to configuration information by data parsing to be resolved；Dynamic link library includes the element information of data to be resolved (all transportation industry data), (or being generated by developer) is automatically generated according to Code Template according to specification by configuration information, dynamic link library be as assembly presented in, loaded by the application program using this technical method and use, for the characteristic support of the field of traffic support to multiple dynamic link libraries.
Step 2: when processing traffic data, first obtain data to be resolved, according to dynamic link library, data to be resolved are carried out pretreatment, perform corresponding operational order after pretreatment again.
Dynamic link library realization on each programming language is different, and C++ is upper mainly to be realized in the way of dll file, and on Java, then dynamic load and modularization mode with Jar packet mode realizes.Such as OSGI provides the modular a series of specifications of mobilism towards the dynamic modeling system of Java.
Need to load dynamic link library system initialization when, the mode of follow-up employing periodic monitor is updated loading.System, processing all kinds of transportation industry data when, can select corresponding processing mode to carry out data parsing process according to data category.
It addition, perform corresponding operational order in above-mentioned steps 2, operational order therein includes storing the operation such as data, distribution data.The process being wherein stored in data (including log-on data and amendment data) is as follows: generates interface interchange parameter array by the requirement of each interface parameter list, then parameter array generates URL parameter string, the URL parameter string of generation is sent to platform interface；After platform interface receives URL parameter string, it is resolved, and be stored in platform respective attributes；
The process of distribution data is as follows: request data generates URL request string, the URL request string of generation is sent to platform interface；After platform interface receives URL request string, it is resolved, and perform this request data generation reply data, and data transmission will be replied to user side；The subscription information of rest interface log-on data distribution, subscription information is to store with the form of key-value in systems, subscription information contains the authority information of user side and each information service, authority information can get the subscribing relationship of data field, thus the subscription of data field rank can be realized.Such as positioning data of vehicles information, data source reports and contains (information of vehicles, longitude and latitude, warning message, speed mileage etc.), certain information service is not concerned with the warning message of vehicle, then need to safeguard this authority in subscribing relationship, after data distribution, this information service can only get information of vehicles and longitude and latitude, thus save the network bandwidth and improve data safety.
The present invention uses such scheme, initially sets up platform, and platform is to be realized by the dynamic link library that can identify configuration information, then data to be resolved are carried out pretreatment, obtain the configuration information that platform can identify automatically, then, loaded by this dynamic link library and resolved.
Further, in order to improve transmitting efficiency and ensure the confidentiality of data, in described step 2, the URL parameter string generated also being carried out base64 process, do so more conducively GET mode carries out the transmission of data.Base64 is one of coded system being commonly used in transmission 8Bit syllabified code, specifically see RFC2045～RFC2049, has the detail specification of MIME above.Base64 coding can be used for transmitting longer identification information under HTTP environment, such as, in Java Persistence system Hibernate, just have employed Base64 and one longer unique identifier (UUID of generally 128-bit) is encoded to a character string, as the parameter in HTTP list and HTTP GET URL.In other application programs, the most usually needing binary data coding is to be suitable for being placed on URL(to include hiding form fields) in form.Now, using Base64 coding to have unreadable property, i.e. coded data with the naked eye will not be immediately seen by people.
Further, in order to prevent sending repeatedly the situation of same request at synchronization owing to network problem or other reasons cause, described URL request string includes request data, timestamp and queue number.Wherein, queue number (is designated as call_id), and the serial number that is call_id for the queue of request is the queue number asked each time, the api interface opened to all of platform initiates request when, all sends a call_id parameter.Timestamp is the system time that current request sends, and is accurate to millisecond value.Each time the call_id parameter of calling interface all can not equally, after once call should be bigger than front.Typically taking millisecond number the most permissible, if to call continuously, best do-it-yourself controls, and the most often calls once, and call_id is increased by 0.001.Platform uses call_id and timestamp to prevent owing to network problem or other reasons cause and sends repeatedly the situation of same request at synchronization.
This dissemination system can use configuration file and the mode of rest interface registration, it is not necessary to amendment program code can realize parsing and the distribution of data.Use the mode of dynamic link library, different analysis modes, preferable usability, versatility can be used for different data forms.When in the face of complicated and diversified transportation industry data, there are efficient, safe, data parsing flexibly and process performance.
