Background technology
Nuclear power plant containment shell is the building enclosure of nuclear reactor, and be the 3rd road safety curtain after nuclear burning involucrum, pressure vessel, its structural safety importance is unrivaled.According to International Atomic Energy Agency's relevant regulations, need regularly to carry out impermeability test, strength test and daily security monitoring with in-service period after nuclear power plant containment shell structure building.Given this, in the work progress of containment, pre-buried or a large amount of permanent instrument measured the various distortion of containment has been installed at structures outlet side-wall in xoncrete structure.Nuclear power technology before two generations half, above-mentioned measurement instrument is dispersed in the different position of structure, is all generally measure by manually running a plate reading table for employing hand-held at duration of test.Current, for the EPR three generations nuclear power technology of Taishan nuclear power station, according to the consideration of the safety detection of structure, more than 700 Zhi Yibiao are laid, the parameter kind that these instrument detect is many, capacity large, relies on simple original artificial race point mode to collect data and realizes regulation and the designing requirement that monitoring can not meet nuclear power monitoring.Simultaneously, along with the present age to the lifting of Nuclear Safety management awareness and the demand that saves labour turnover urgent, nuclear power technology before original two generations half, in the urgent need to carrying out transformation and upgrade to original test macro, be imperative by transforming the automatically-monitored technology of integrated a kind of structural safety.
Other non-core electrical domain, for the building structure of the international people's livelihood of important impact and public safety, as National Convention Center, stadium, Loads of Long-span Bridges etc., according to designing requirement, also need to carry out structural safety monitoring in the construction of structure or run duration, therefore often laid a large amount of measuring instruments according to the importance degree of structure and the requirement of design, the monitoring of these structural safetys also needs the monitoring technique of integrated a kind of robotization.
Therefore known, in the prior art, for the nuclear power plant containment shell structural safety monitoring technology in current two generations half, achieve design and the laying of structure health monitoring sensor.Fig. 1 is nuclear power structure monitoring system Organization Chart of the prior art, and as shown in Figure 1, nuclear power structure monitoring system of the prior art comprises measuring junction 11, terminals 12 and acquisition terminal 13.Wherein, the sensor of multiple kind can be included in measuring junction 11.Such as, shown in Fig. 1 the 1st class sensor 111 ..., N class sensor 11N etc.In terminals 12, there is N number of terminal box, each terminal box 121 is connected by cable with a certain class sensor corresponding to it, and such as, the terminal box 121 shown in Fig. 1 is connected by cable with the 1st class sensor,, terminal box 12N is connected by cable with N class sensor.Acquisition terminal 13 can comprise multiple portable digital reader, wherein, and all corresponding corresponding portable digital reader of each class sensor.Such as, the 1st class portable digital reader 131 shown in Fig. 1 is connected by data line with terminal box 121 ..., N class portable digital reader 13N is connected by data line with terminal box 12N.
According to said structure, sensor in structure monitoring system of the prior art is all that distributing is arranged nearby, and use portable digital reader to carry out data acquisition by artificial mode of running point, then carry out passing judgment on and control according to collection the data obtained manual entry and analyzing and processing, therefore lack the datamation data acquisition and controlling device of integrated form.
For other non-core electrical domain, structural safety monitoring achieves design and the laying of structure health monitoring sensor subsystem, for data gathering system except artificially collecting, also have and be integrated with the higher collection system of semi-automatic or automatic degree, but each funtion part of the monitoring system that these are semi-automatic or automaticity is higher is all separate, the not collection cabinet of becoming one.The basic parameter of the collection structure needed in manual intervention situation in batches substantially for the data gathering system of semi-automation.And the collection system that automaticity is higher, its signal type that can gather is also often all more single, and the harvester of often kind of signal type works alone, and final data is by manually collecting and analyze last realization manually to monitoring and the assessment of structural safety.
Flourish in view of current Nuclear Electricity, applying of Generation Ⅲ, the application of Large Copacity, multi-parameter detector table, in the urgent need to developing a set of standardized structural safety monitoring technique, researches and develops the structural safety automatic monitoring standardization control cabinet matched.
