Information storage mechanism on vehicles registration into data base Various connection options are shown on Pic.1 for FALCON device (reader) with central computer, i.e. system server. Data storage on vehicles registration, i.e. storage of detected TAGs ID numbers with data on place and time of detection is performed at system server. Falcon Service application enables the process of registration data storage as well as monitoring and operation of FALCON devices in the system. Pic. 1 Connectivity options for FALCON reader with system server concerning communication In formation on TAG detection is stored into data base on server side. As per detection information, i.e. TAGs registration, various analysis and statistics could be performed. Information, i.e. TAG detection note contains the following: Registration note unique number (field Id_Reg); TAG ID number registered (field Id_Tag); Tag`s place of registration (field Id_Checkpoint), i.e. FALCON reader address within registration system that detected TAG; Date and time of TAG detection (field DateTime) and Probability of registration accuracy (field Probability). Part of the chart in data base with information on vehicles registration (of TAGs) with 2 places of registration (Id_Checkpoint 11 and 61) is shown on Pic. 2. Pic. 2 Part of the chart with data on vehicle registration from the places of registration 11 and 61 1
The registration accuracy probability (field Probability) is the parameter to be analyzed only if the system operates in places being at the same time the entrance and exit of the zone of interest for vehicles monitoring (2 readers operation in pair configuration). It is possible to get configured data base for data storage on vehicles registration (TAG) or connect the necessary charts to the existing data base. Application for FALCON reader operation and registration data storage into data base has the option for configuration of location and name of data base where there is a chart with vehicles registration data. The chart name, fields names within the note, as well as note structure are fixed and documentation is available for FALCON system users. On the basis of precisely defined format of the note the charts with TAGs registration into data base it is possible to realize user`s application for check-up, analysis and reports composition for concrete application. Application for storage of information on TAGs registration On the server side for vehicles registration system there is Falcon Service application ensuring monitoring and control of FALCON reader, as well as collection, primary processing and storage of data on TAGs detection. Falcon Service is Windows application which communicates with FALCON readers through real and virtual series ports (RS232). The collected data on TAGs registration are stored into data base. System organization concerning Falcon Service application, data base and FALCON reader functioning is shown on Pic.no. 3. Pic. 3 System organization database, Falcon Service application and FALCON readeres Falcon Service application basic characteristics are the following: Communication with several FALCON readers through real and virtual series ports (RS232 ports); implemented communication protocol with FALCON reader per RS232 series connection and communication parameters: 19200bps, 8N1; completely ensured maintenance mechanism for each reader independently, containing: reader operation configuration, status analysis, accurate time set-up, TAGs detection data receipt, communication interruption analysis, etc; ensured mechanism for data processing on TAGs registration from the readers operating in pair configuration; 2
configuration of FALCON system operation through configuration data base in XML format (Pic.no. 4); configuration of each reader operating mode independently through parameters within unique XML configuration data base; configuration of parameters for algorithms for primary data processing on detected TAGs within Falcon Service application; configuration of route to data base with chart for storage of detected TAGs registrations; configuration of the reader synchronization mechanism within the system. Pic. 4 Part of XML configuration data base for configuration of FALCON system operation Falcon Service contains implemented mechanism for TAGs detection processing with 2 readers operating in pair configuration, i.e. in configuration where one reader stands for place of vehicle registration on its entrance, and the other reader on the exit. This application enables registration of several readers operating independently or in pair. Each reader communicating through series port gets its unique address within the registration system. Reader address and device operation parameters (RF exit power level, operating mode, TAG type ) are defined in group or separately for each reader through XML configuration data base. Fields specification (tag) defining parameters Falcon Service application operation within XML configuration data base are available to every user of FALCON system. By simple change of XML configuration database parameters you can influence system operation concerning: radiation level, detection type, device operation mode, place of data registration, i.e. data base etc. 3
Pic. 5 Window for configuration data base selection of FALCON system for vehicles registration Pic. 6 Window for activation of Falcon Service application When XML data base is chosen, containing configuration of FALCON system operation (Pic.no. 5) window for activation and disactivation of Falcon Service application is opened (Pic.no. 6). Further operation of the system is autonomous. It is possible to ensure data that are written into special chart of data base, containing information on change of device operating mode, i.e. detection of communication interruption, starting application, etc. 4
