Description

Cathodic protection potential note telemetering device

Technical field

The utility model belongs to measuring technique, is specifically related to the remote measurement of potential data.

Background technology

The anticorrosion of the metallic facilities such as oil transportation, gas transmission feed channel and storage tank of long distance is the important topic of oil and gas industry, to improving economic benefit of enterprises, guaranteeing that China's energy production safety has extremely important meaning.In decades, the anticorrosion work of China has had significant progress, has adopted impressed current cathodic protection widely; technology such as sacrificial anode is anticorrosion; no matter adopt which kind of anticorrosion technique, the monitoring of anticorrosion ability all is crucial, and it directly influences the success or failure of anticorrosion work.By corrosion monitoring, both can grasp the etch state and the effect of protected object, can grasp the running status of impressed current cathodic protection equipment or sacrificial anode again.In the past, the monitoring of anticorrosion ability all was by realizing to the current potential of the protected body of on-the-spot test that manually it is big to do the one side labour cost like this, and can't monitor constantly; Often can't monitor for a long time in place on the other hand, have a strong impact on the effect of anticorrosion work away from website.

Summary of the invention

The purpose of this utility model provides a kind of cathodic protection potential note telemetering device; utilize the GSM communication modes to realize that cathodic protection potential is long-range, automatic, regularly measure; overcome big by artificial labour cost to on-the-spot test, can't monitor constantly, often be negligent of for a long time monitoring away from the place of website, had a strong impact on the deficiency of anticorrosion ability.

Cathodic protection potential note telemetering device of the present utility model is by the center control section that is arranged on the Centralized Monitoring chamber and divide to be located at and respectively monitor each extension set that the place is connected with contrast electrode and form.

The center control section comprises personal computer, system software, GSM main frame in the personal computer of packing into,

System software wherein comprises that system is provided with module, current potential statistical form module, time Potential distribution module, stake point Potential distribution module, database module, and main frame comprises GSM SMS module, switching power supply, level shifter interface plate.Switching power supply inserts the GSM SMS module, and the level shifter interface plate is picked out by the GSM SMS module, and the interface on the level shifter interface plate connects personal computer.

Divide the extension set that is located at each monitoring location of setting to constitute by GSM SMS module, high-precision A/D potential acquisition module, anti-thunderbolt unit, switching power supply and module software.Anti-thunderbolt unit connects contrast electrode, and high-precision A/D potential acquisition module connects anti-thunderbolt unit, and the GSM SMS module connects high-precision A/D potential acquisition module, and switching power supply inserts GSM SMS module and high-precision A/D potential acquisition module respectively.

For powering to extension set, in the potential acquisition module of extension set and the power connector end peace change-over switch of SMS module, with alternating-current switch stabilized voltage supply be connected in parallel D.C. regulated power supply and battery overdischarge protected location at the monitoring location that does not have the net power supply.Form the dual-purpose extension set of AC and DC.

Principle of work of the present utility model is: when the monitoring personnel want extension set to gather the instruction of protection potential or main frame timing automatic when each extension set sends the instruction of collection current potential in one of input on the personal computer of center control section; this instruction is sent by SMS module; after receiving instruction, the SMS module of each extension set will gather the current potential of the protected body of each website by the potential acquisition module; and this protection potential value issued the center control section by SMS module; the center control section is received after the protection potential value that each extension set sends automatically with its storage; the line data of going forward side by side is handled, and produces the needed various charts of managerial personnel.

Good effect of the present utility model is: utilize public mobile telephone network; communication mode with note; realized centralized detecting to the monitoring place of a plurality of dispersions; can be automatically, regularly the anticorrosion state of protected body and the duty of corrosion protection equipment are monitored in real time; greatly reduce the cost of anticorrosion management; improved work efficiency, made anticorrosion ability that reliable assurance arranged.Be mainly reflected in:

1, central computer can timing automatic be gathered the cathodic protection potential of each test point (extension set collection point), and every day, number of times, the acquisition time of timing acquiring all can manually be provided with.Can collect the data that can reflect protected body state according to the potential change rule of each protected website like this.

2, central computer can be sent the cathodic protection potential of any one monitoring point of instruction acquisition (extension set collection point) at any time by the operator, and does not influence the timing acquiring setting.The artificial current potential of gathering is during for protected body state generation ANOMALOUS VARIATIONS, provides means of understanding presence states in real time to managerial personnel.

3, central computer can generate the cathodic protection potential statistical form in any one monitoring point random time section automatically according to the data of gathering.

4, central computer can generate " day current potential---the time distribution map " of any one monitoring point in certain January automatically according to the data of gathering.

5, central computer can generate " month current potential---the time distribution map " of any one monitoring point in a certain time automatically according to the data of gathering.Can allow managerial personnel recognize the shielded state of certain protected point intuitively like this, whether have other factors that the protection effect is exerted an influence.

6, central computer can generate the potential image of any one day all monitoring points automatically according to the data of gathering.Can allow managerial personnel fully grasp the overall picture of all protected station states in its compass of competency like this.

7, native system has monitoring point current potential overload alarm function.Prescribe a time limit when the current potential that collects is higher than the predefined current potential upper limit or is lower than under the predefined current potential, system will send chimes of doom.Managerial personnel can in time learn the abnormal conditions that protected body takes place like this, so that in time take measures, avoid the generation of accident.

8, native system has the monitoring point current potential deixis that transfinites.When the current potential that collects is higher than the predefined current potential upper limit or is lower than predefined current potential lower limit and just often, system all can identify out with the different colours that is provided with in all charts three kinds of status datas.This is convenient to managerial personnel and analyzes protected body state unusual reason takes place, so that take correct solution.

9, central computer can with system acquisition to all data, generation the chart long preservation, have access at any time, also can print, back up file.This is that long-term normal science information of managing basis is carried out in anticorrosion work.
