Description
Technical field
The present invention relates to protect the data of debugging stake and current potential stake to detect automatically, gather and put in order, and configuration computer galvanic protection data processing software, the cathode protection technology field in the electro-chemical protection belonged to.Specifically, be that a kind of galvanic anode protection detects treatment unit automatically.
Background technology
Be embedded in underground or lay underwater pipeline or steel structure, be provided with cathodic protection system mostly and give protection against corrosion.Wherein, the galvanic anode protection system is one of most widely used galvanic protection preservative system.System is provided with the debugging stake and the current potential stake of some amount, by exchanging the detection of test pile and current potential stake galvanic protection data, can safeguard, handle system.At present, the galvanic anode protection system that widely applies protects the detection of parameter to handle both at home and abroad, adopts manual type to detect data.Manual type utilizes detective pole that the protection parameter is measured one by one, generally need protective current, the protection potential of every pipeline be detected one by one, also needs to detect each anodic open circuit potential and protective current sometimes.According to protecting the different of pipeline and anode quantity, the parameter that needs to measure has a plurality of.Measurement point is many, workload is big, has not only reduced working efficiency, and accuracy also is affected, and manual type detection data, and data of every detection are all wanted holding bolt of dismounting, can cause certain influence to securing system electric connection reliability.As seen, there are following many shortcomings in existing galvanic protection Data Detection Technology: 1. no matter be debugging stake or current potential stake, when carrying out the galvanic protection Data Detection, can only take the primary manual type, do not change recent decades; 2. carrying out to use reference electrode (copper sulfate) when current potential detects, near the soil insertion debugging stake, the current potential stake; 3. in cathodic protection system, need regularly to detect the several number certificate of debugging stake, current potential stake, as: the protective current of total protective current, total protection potential, each anode open circuit potential and each anode and pipeline enclosure etc.During Data Detection, need dismantle each anode and each pipeline enclosure respectively, joint bolt and metal connecting piece (or cable) on the stake position, also to reconnect after having detected, fastening, time-consuming, the inefficiency of requiring great effort, especially in pipeline and a fairly large number of system of anode, workload is huge; 4. manual detection speed is slower, finish the Data Detection of each position of whole protecting system successively, required time is longer, like this, just make that the Data Detection timed interval of each interdigit is bigger, can't accomplish that securing system detects " the basic same period, the synchronism " of data, also is unfavorable for the raising of whole protecting system level; 5. frequent demounting bolt and web member (or cable) can influence the electric connection of securing system debugging stake, current potential stake, make bolt and web member generation corrosion easily, thereby the Data Detection accuracy is reduced greatly, also the whole protecting system are caused detrimentally affect; 6. detecting data can only manual record and processing, inefficiency; 7. a stake open-air setting, after for some time (several years), " numbering " damaged easily, blured, and gives a location, position, recognizes and bring difficulty, and obscure with near stake position easily, is unfavorable for the securing system comprehensive treating process; 8. owing to do not have computer and high efficiency galvanic protection data processing software, the securing system processing horizontal fluctuates, and can't constantly upgrade.
