The intelligent monitoring and early warning system for pipeline safety comprises a plurality of cathode potential collecting systems, a plurality of interference information collecting systems, a power management system and a signal sending system which are arranged in the direction of a pipeline. By selectively collecting various kinds of interference information and meanwhile collecting cathode potential information, the intelligent monitoring and early warning system for pipeline safety is used for monitoring the pipeline correctly, timely and effectively, and therefore can send out early warning information before leakage is caused when the pipeline is being broken; management personnel can timely arrive at accident sites to stop destruction, and pipeline destruction accidents can be effectively restrained.
Description
Technical field
The present invention relates to a kind of pipe safety intellectual monitoring early warning system, particularly relate to the antitheft detection early warning in oil, natural gas transport field.
Background technique
The defeated rock gas of length of China, petroleum pipeline are laid hundreds thousand of kilometers of distance.In recent years, oil and gas pipes is very severe by the situation of damage from third-party, has become the primary factor that threatens oil gas long distance pipeline safety.Wherein artificial main failure mode is drilling hole of oil stolen, after there is drilling hole of oil stolen situation, has not only caused the loss that oil product is stolen, and causes corrosive pipeline to destroy to shorten pipeline working life.More seriously oil product is revealed the serious consequence that ejection causes casualties, and causes serious environmental pollution and environmental improvement loss.
Pipeline unit of operation be safeguard oil and gas pipes integrity and prevent damage from third-party, progressively on pipeline, apply the safe operation that some technological prevention means ensure pipeline, related industry and the state of the art are as follows:
1) transient negative pressure ripple method Systems for Oil Pipeline Leakage warning system for real time monitoring:
Serious leakage occurs the method could report to the police, and pipeline oil transportation pressure itself fluctuates when large and cannot normally work.
2) pressure flow associating diagnostic method leakage alarm system for pipeline:
Serious leakage occurs the method could report to the police, and the problem that pipeline cannot be worked when large because of landform drop is very outstanding.
3) the line leakage system based on fiber grating sensing technology:
The method must be laid special optic fibre with ditch when buried pipeline, and adopts the high sensor special of price and processor, installs, user cost is high, and cannot be applied to not have the old pipeline of optical fiber.
System is in the past all to detect that to leak be main, so managerial department finding in long-term actual moving process, the defect one of their maximums is to report to the police not in time, lags in response, leakage accident has occurred for a long time often, has caused very large economic loss just to report to the police; The 2nd, system in the past can only be crossed area, level land at device for cleaning pipeline and use, if pipeline is very large at upper and lower mountain region shape drop, and pressure and instability of flow or while stopping transport without pressure and flow, its warning function has just lost effect; The 3rd, the lawless person in society is at pipeline Shang Jie branch, mounted valve, and while taking small flow to steal oily gimmick, alarm system in the past just cannot Normal Alarm; The 4th, often that normal farmland operation, engineering construction etc. are movable as warning message, administrative staff are dog-tired.
The destruction of pipeline often has certain sudden, and when destructive activity occurs, original technology is difficult to find rapidly, exactly destruction, is also difficult to determine destroyed position, and practical effect has a lot of problems and narrow limitation, and unsatisfactory.
Summary of the invention
The present invention is directed to above-mentioned defect, it is a kind of by the selectivity of the various interfere informations of pipeline is gathered that object is to provide, simultaneously by the collection with cathode potential information, come correctly, effectively pipeline monitored timely, thereby can occur to destroy before also not causing leakage at pipeline and send prewarning information, administrative staff's continuation that spot of the accident prevent to be destroyed that can arrive in the very nick of time, the generation of containment tubes road destructive incident effectively.
