Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done further to describe in detail:
Fig. 1 is the process flow diagram of controlled device inventory automatic generation method, and the present invention is applied in the PID system of power plant, is used for each controlled device of system diagram is analyzed, to generate the controlled device inventory.Wherein controlled device mainly comprises the instrument of installing on the valve in the system, the pipeline that this valve is installed and this pipeline.Automatic generation method is based on the support of KKs coding techniques and computer program, and concrete steps are as described below:
A. to scanning based on PID designed system figure, gather 16 codings of each IO measuring point among the figure, in the general system diagram thousands of measuring points are arranged; For example collect a group coding: 30LBQ60AA402XB01,30LBQ60AA402XB91,30LBQ60AA402XB02.
B. three 16 codings that gather among the step a are sorted, decompose, determine the KKs coding of controlled device according to front 12 codings, determine the steering order of controlled device according to rear 4 coded signals;
Continuation of the previous cases obtains 30LBQ60AA402XB01 after the ordering
30LBQ60AA402XB02
30LBQ60AA402XB91
Front 12 that analyze this group coding are 30LBQ60AA402, be the KKs code type of valve, and steering order have three to be respectively: XB01, XB02, XB91.
C. determine the correlation parameter of valve: according to the steering order of the same valve of determining among the step b and the quantity of steering order, transfer the standard signal type code storehouse in the database, to determine the signal type code of this valve; Determine the subtype of this valve according to the standard controlled device subtype storehouse in the database; Determine title, classification and pipe laying and the area code of valve according to the valve inventory in the database;
Continuation of the previous cases, transfer the signal type code of this valve in the standard signal type code storehouse from database, now find out qualified regular tap type pneumatic valve HS_P2 and single electric control solenoid valve HS_S2, they have three instructions, and instruction also is respectively XB01, XB02, XB91; Further pass through the KKs code of this controlled device valve, the valve inventory of heat engine specialty in the gathering information memory module, the control form of finding the 30LBQ60AA402 valve from inventory is air bladder formula (pneumatic type), is HS_P2 so can make this signal type code.
According to the signal type code HS_P2 of valve, compare with standard controlled device subtype storehouse in the database, be single electric-controlled switch type pneumatic door thereby find out the valve subtype corresponding with this signal type code.
According to the KKs code 30LBQ60AA402 of valve, transfer the valve inventory of the corresponding heat engine specialty in the database, search the valve relevant information and be: the valve title is drain valves before three sections extraction check valves, is the title of valve; The method of operation of valve is air bladder (pneumatic type), is the classification of valve; The KKs code of the corresponding pipeline of valve is 30LBQ60BR401, is the pipe laying at valve place; The mounting points 3F of valve is the area code at valve place.

Continuation of the previous cases, with the KKs code be that the KKs code of the corresponding pipeline of valve of 30LBQ60AA402 is 30LBQ60BR401, be V10C12 according to the information searching of pipeline inventory in the database to the pressure rating of this pipeline, be that pressure rating is 10Mpa (100KGf), the design pressure of this pipeline is 5.37Mpa, meets designing requirement; The material of pipeline is No. 20 steel of carbon steel; The design temperature of pipeline is 337.2 degree.
E. according to the parameter of the definite pipeline of steps d, at first judge under this kind pipe material, whether the pipe design temperature surpasses the maximum temperature limit value, then reports an error as surpassing; As not surpassing, illustrate that the design temperature of pipeline, pipe material selection are reasonable; Determine again the force value of valve according to this design temperature and pressure rating;
Continuation of the previous cases is transferred the materials'use limit value thermometer in the database, and finding pipe material is that the highest Applicable temperature of No. 20 steel of carbon steel is 427 ℃, and this moment, the design temperature of our usefulness was 337.2 degree, did not surpass the highest limit value, and selection does not meet the requirements.And then the force value of determining valve according to pressure rating and the pipe design temperature of pipeline material.
Because temperature in the professional code of storing in the database, force value information data amount are relatively less.When therefore not existing searching corresponding temperature, pressure value, can only extract approximate value, the present invention can be with pressure rating and the temperature rating curve table of valve pressure value with respect to pipeline material, and the refinement of adopting the mathematics method of interpolation to carry out force value is calculated.
At first according to pipe temperature and the pressure rating determined, choose temperature in-scope W
1, W
