And the corresponding evaluation performance of grade is as shown in the table, and by the steel tower safety grades and the corresponding evaluation performance information of grade
It is sent to corresponding output module：
8. a kind of appraisal procedure of iron tower of power transmission line safety evaluation system as described in claim 1-7 any one,
It is characterized in that：This approach includes the following steps：
(1) pass through the collected steel tower status information of each acquisition module in the acquisition module；
(2) collected various steel tower status informations are sent to control module, the control module retransmits described information
To the steel tower safe condition grading module；
(3) the safe condition grading module is determined according to the corresponding steel tower project grading module and Term Weight module
The safe condition score value of the steel tower；
(4) respective modules that the score value is sent to judgment module judge steel tower safe condition grade；If safe condition grade
When being I or II grade, steel tower safety grades and safe condition score information, safe condition class information, iron by steel tower are judged
Tower safety grades information and the corresponding evaluation performance information of safety grades are sent to corresponding output module；
If safe condition grade is III or IV, continue next step；
(5) steel tower load, steel tower use environment and the steel tower drag of acquisition steel tower practical structures and damage information are sent to steel tower
Security performance judgment module；The steel tower security performance judgment module is established mechanics analysis model according to steel tower load simultaneously and is judged
Its security performance grade；
(6) its described security performance class information and the safe condition grade are sent to comparison module；When steel tower safety
When state grade two level than steel tower security performance lower grade or three-level, the steel tower safety grades drop level-one or two level determine；
Information after comparison is sent back to corresponding judgment module by the comparison module again, by the safety grades of the steel tower into
The last determination of row；
(7) safe condition score information, safe condition class information, the iron for the steel tower for being finally III or IV by safe condition grade
Security performance class information, steel tower security performance class information, steel tower safety grades information and safety of the component of tower etc.
The corresponding evaluation performance information of grade is sent to the corresponding output module.
