3) Setting the pipe distribution rules of elbows, tees and transition pieces of each type of pipe according to all the types of the pipes searched in the step 1);
firstly, selecting a pipeline type and a pipe type, then setting a default pipe, wherein the default pipe is selected when the pipeline is not matched with a conforming rule, then adding other pipe types, and adding a logic rule for each pipe type. The logic rules consist of one group of rules or multiple groups of rules, wherein each group of rules has a logical AND relationship, so that the logic AND relationship can be satisfied at the same time, and the group-to-group relationship can be freely set as a logical AND relationship or OR relationship. Each rule consists of three parameters, conditions and values, which are indispensable;
4) Selecting a pipe fitting to be detected according to all the pipe fitting types in the step 2);
5) Comparing each pipe fitting with the pipe distribution rule of the pipe type in the configuration, selecting pipe fitting conforming to the rule, and if no matched pipe fitting exists, using a default pipe fitting;
when matching the pipe laying rules, firstly searching the pipe laying rules of the pipe type in XML, then judging whether the rules of each pipe fitting are matched in sequence, if so, selecting the pipe fitting, and if not, adopting a default pipe fitting;
6) The current tubular is replaced with the correct tubular type.
And thirdly, storing all the set management rules in an XML file in a specific format, wherein the XML file can be reversely analyzed into identifiable rules for matching and searching correct pipe fittings.
And when the pipe fitting is replaced in the step six, ensuring that the new pipe fitting and the previous pipe fitting are the same type of pipe fitting, otherwise, the communication mode of the replaced pipe is possibly wrong.
The beneficial effects of the invention are as follows: the user can configure the pipe distribution rule according with practical application through the system, and test the pipe fitting in the original BIM electromechanical model to correct the wrong pipe fitting type.
