the engineering symbol information processing module: the system comprises a server, a plurality of engineering symbol definition information files, a plurality of service servers and a plurality of service servers, wherein the engineering symbol definition information files are used for storing the definition information of engineering symbols by adopting a standard document of XML, the definition information of the engineering symbols obtains corresponding engineering symbol definition information files in the XML format from the server in a WebService mode, the engineering symbol definition information files store the engineering symbol definition information designed by a user in a structured mode, and the structure supports the storage of a plurality of symbol definition information in the same file and the nested use of the symbols; simultaneously, the input parameters of the engineering symbols are stored in a script file format, the recorded contents comprise variable values and character contents in the engineering symbols, and the script format can accept the parameter values and characters of any external engineering symbols meeting the specification requirements;
the engineering symbol generation module: comprises a data processing engine and an engineering symbol generating engine, a WebService service provided by a server side acquires definition information of engineering symbols,
the engineering symbols are defined by XML format files, a template is analyzed in a program and the engineering symbols are drawn by combining input parameter values, finally, the picture files representing the engineering symbols are output and used for various application scenes needing to display the icons, all the graphic elements need to be positioned by coordinates, the unit of the coordinates is a pixel px, in the definition of the icons, the limitation and the positioning of the graphic size range are carried out by a Rect attribute, a coordinate axis takes the lower left corner as an origin (0,0), the Rect attribute values are four integers which are separated by commas and respectively correspond to a left corner, a lower bottom corner, a right corner and an upper top, the custom symbols are drawn into needed symbol pictures by analyzing the template and the parameters by using simple graphic elements, the needed symbol pictures comprise common graphic elements, the common engineering symbols are drawn by combining the simple graphic elements, and no association relationship exists among the graphic elements, drawing independently, wherein the drawing sequence is carried out according to the configuration sequence in the XML file and is drawn from top to bottom; the engineering symbols in the system are all self-defined symbols, and template files of the self-defined symbols are mainly used for storing detailed configuration information of various graphic elements; the method comprises the steps of analyzing the engineering symbol definition information by a data processing engine according to the specifications, recording detailed information of drawn engineering icon examples for recording example information of engineering icons and facilitating next calling and displaying, re-drawing and displaying engineering icon pictures by analyzing the information of the engineering icon examples by the engineering icon engine when calling again, describing the engineering icon examples by using a string of scripts with special marks as a recording method of engineering symbol input parameters, and defining the basic format of an input parameter file as follows:
#％TS；ID＝；L＝XX；H＝XX；C＝ParaCount；V1＝A；V2＝B；…％#
the meaning is as follows:
"; "is a separator;
"#%" is the start mark;
"TS" is a symbol identifier;
"ID" is the unique identification of the icon definition template;
l is an abbreviation of Length and represents the Length of the process symbol, and the Length value of the process symbol is equal after the equal sign, and the unit is millimeter or pixel;
h is an abbreviation of Height, represents the Height of the process symbol, and is equal to the Height value of the process symbol, and the unit is millimeter or pixel;
c is an abbreviation of Count, represents the number of parameter values of subsequent process symbols, and is the actual number of the parameter values after equal sign;
the' V1 ═ V2 ═ is parameter names, the number of parameters of each process symbol is different, the parameter names are also different, and the equal sign is the parameter value of the parameter;
"% #" is an end mark;
analyzing the acquired engineering symbol input parameter file by a data processing engine according to the above specifications to acquire related engineering symbol data information, transmitting all information to an engineering symbol generation engine after acquiring definition information and input parameters of the engineering symbols, drawing the engineering symbol data received by the engineering symbol generation engine into engineering symbols in EMF format by a drawing engine according to the acquired data parameters, and storing the final engineering symbols in a metafile manner;
the engineering symbol database module: the system comprises a data storage module, an engineering symbol generation module and a database, wherein the data storage module is used for storing data generated by the engineering symbol generation module and forming the database;
the project report inserting module: the system is used for calling data in the engineering symbol database module, so that a user can directly apply the engineering symbol data in the database module to the business field of the user.
