Description
Technical field
The invention belongs to the measurement mechanism class, relate in particular to the pick-up unit class of corrosive pipeline and cathodic protection.
Background technology
The pipeline transportation of liquid is industry, the easiest a kind of means of transportation in the public life, as the pipeline transportation of oil, combustion gas, tap water, chemosynthesis agent etc.After the pipeline that lays used through certain hour, corrosion phenomenon took place in regular meeting, in the course of time, can cause pipe leakage, broke to wait damage, and the transportation of weight person whole pipe is paralysed, and generation substantial pollution accident influences normal commercial production and people's lives.To this,, maintain, repair and upgrade for detecting pipe corrosion condition.The normal utilization of people preset guard electrode, adopts artificial multimeter to measure activity value, or adopts radio transmission to measure its data.The former operating personnel need make a difficult journey, point-to-point measurement, and time-consuming, effort, the reliable measuring data degree is low; The numerous transmitters of the latter are subjected to power supply restriction and cost high, are difficult to implement, thereby bring many difficulties to the detection of pipe cathode corrosion, influence pipeline transportation work directly or indirectly.
Summary of the invention
The purpose of this invention is to provide a kind of cathode protecting signals of pipeline detection system, it is applicable to the pipe cathode corrosion and routine is carried out in protection or emphasis is patrolled and examined detection.
The object of the present invention is achieved like this:
A kind of cathode protecting signals of pipeline detection system, it comprises:
1, one pipeline cathode protection detection of stored device is used for instruction in sample time, carries out the data monitoring and the storage of cathode activity value.
2, one pipeline cathode protections are patrolled and examined the sample acquisitions device, are used for sample acquisitions and the input execution of program instructions and the storage of the cumulative measurement data of pipeline cathode protection detection of stored device.
3, one computer processor units, it is provided with a pipeline cathode protection and patrols and examines the detection software package in computing machine, be used for processing and instruction executive routine and storage that pipeline cathode protection is patrolled and examined the sample acquisitions data;
4, interface cable connects computer processor unit and pipeline cathode protection and patrols and examines the sample acquisitions device, is used for input data signal.
Because the present invention has adopted above technical scheme, thereby has:
1, once all gather whole measurement data in the special time.
2, regular, timing automatic detects measurement data and storage.
3, can save a large amount of personnel, the vehicles, conveniently regularly patrol and gather or spot test with a focus on.
4, the apparatus system simple structure, easy to operate.
5, data comprehensively, accurately.
6, in time sorted generalization is handled, and scenting a hidden danger solves early, prevents the protection of pipeline breaking and cathode signal.
