Attached drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention,
For those of ordinary skill in the art, without any creative labor, it can also obtain according to these attached drawings
Obtain other attached drawings.
Fig. 1 is the flow chart of pipeline cathode protection validation checking method provided in an embodiment of the present invention；
Fig. 2 is the structure chart of pipeline cathode protection validation checking device provided in an embodiment of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
It is the flow chart of pipeline cathode protection validation checking method provided in an embodiment of the present invention referring to Fig. 1, Fig. 1, such as
Shown in Fig. 1, in one embodiment, method includes the following steps:
Step 101, identification Target pipe have the risk zones of corrosion risk, and corrode according to the Target pipe is influenced
The factor of risk confirms the type of the risk zones.
It should be understood that the technical solution of the present embodiment is mainly used in the conveyance conduits such as various petroleum, natural gas, this
A little conveyance conduits may be embedded in underground, it is also possible to be directly exposed to field, it is also possible to need by river, so while respectively
The influence of kind environmental factor and internal factor will lead to it and corrode, and corrosion of metal is actually the mistake of metal oxidation
Journey.
The factor that Target pipe corrosion risk is influenced in the present embodiment includes but is not limited to the humidity of surrounding, temperature, soil
In contain Inorganic Salts, be arranged outside Target pipe casing, pipeline setting when intersection clear distance and parallel clear distance, use
The various inside and outside parameter informations that will cause influence on the corrosion of Target pipe such as structure, the material of insulating part.
However in actual use, a part of external factor can be effectively reduced by various means to protect cathode
For example the influence that exchange clutter interference generates is arranged by setting drainage groundbed in the influence for protecting validity.

Corresponding Detection task is further generated according to the type of risk zones in the present embodiment, due to the risk divided
The type in region is therefore, to be divided into the risk zones pair of same type because usually determining according to influence corrosion risk
The corrosion risk answered is also identical.However for different corrosion risks, in order to test the operation of its cathodic protection system
State, the parameter for needing to detect be also it is different, therefore, in the present embodiment generated according to the type of risk zones corresponding
Detection task, the corresponding Detection task of the risk zones of each type are for the phase paid close attention to required for the type risk zones
Close what cathode protecting parameter was determined.
Step 103, the cathode protecting parameter that the Target pipe is acquired according to the Detection task, and judge the cathode
Whether Protection parameters are in predetermined safe range.
After collecting the cathode protecting parameter of Target pipe according to corresponding Detection task, further according to the rule of budget
Then judge whether cathode protecting parameter is in predetermined safe range.
If step 104, the cathode protecting parameter are in predetermined safe range, the cathodic protection system is being confirmed just
Often operation.
If step 105, the cathode protecting parameter are not in predetermined safe range, the cathodic protection system is confirmed
It does not operate normally.
Obviously, if measured cathode protecting parameter is in predetermined safe range, prove exist in Target pipe
The target risk region of corrosion risk has obtained effective protection, and if be not in if there is measured cathode protecting parameter
In predetermined safe range, then the cathodic protection of the target risk point is proved there may be exception, repair etc. further
Processing operation.
The present embodiment can the difference risk zones according to present in pipeline generate corresponding Detection task and can be directed to
Detecting to risk existing for pipeline for property, can obtain Target pipe cathodic protection system operating status, while can also subtract
Few workload, promotes detection efficiency.

Step, comprising:
Obtain the test pile information that the cathodic protection system of the Target pipe includes；
The test pile installation is confirmed according to the factor for influencing the Target pipe corrosion risk, wherein the test
Pile installation is identical as the type of attached risk of risk zones where influencing the test pile.
Since the test to Target pipe cathodic protection system is the test by being set to each position of Target pipe
What stake was realized, the present embodiment is further managed cathodic protection system based on test pile.
In the present embodiment, the test pile information that the cathodic protection system of Target pipe includes is obtained first.It is specific real one
Apply in mode, test pile information specifically includes the information such as position, number, the coordinate of test pile, so as to can by test pile into
Region corresponding to row positioning pipeline corresponding with can conveniently determine the test pile when counting.
It is actually logical that different Detection tasks, which is executed, to detect the operating status of each risk zones cathodic protection system
It crosses test pile test and obtains the cathode protecting parameter of each region, therefore further classify to test pile in the present embodiment,
In order to execute Detection task.Specifically, in a specific embodiment, can be test pile installation according to the influence survey
The risk factors Type division of risk zones where test pile, such as the test pile for covering area under control is divided into tube-in-tube pile, by confluence
Test pile be divided into confluence stake etc..
Due to the test pile of same type need the data type that measures be also it is identical, by according to risk in the present embodiment
The type in region is managed test pile, facilitates unified test and data acquisition, improves the efficiency of management.
Optionally, the cathode protecting parameter step that the Target pipe is acquired according to the Detection task, comprising:
Detection task if it exists then acquires the yin for including in the Detection task according to default detection program and data template
