Description
Technical field
The present invention relates to the intelligence decompression monitoring pipe in urban duct natural gas transportation field, more particularly to a kind of operation under pressure
Reason system.
Background technology
Currently existing city gas pipeline operation under pressure equipment is by the way of traditional manual measurement pressure to construction
The pressure at scene is measured and monitored.The mode that manually communicates transmits information at the same time.
Current domestic situation is that traditional artificial decompression handwork is needed in the range of the near 80-100Pa of gaseous-pressure,
Harmful effect can be caused with gas to user, the general job time can only be selected in user and carry out at narrow-minded night.Operation is depressured, also
Need to close several voltage regulating stations or pipe valve, in many places, pocket watch, observed pressure are, it is necessary to largely coordinate personnel.Because this biography
The pressure of system mode setting and monitoring point is required for after artificial reading mutually transmitting information again, while occurs combustion gas in order to prevent
With the mixed gas of air, personnel can only be leaned on to be controlled by direct-reading pressure monitoring devices, therefore pressure reading floating is larger,
The change from tens Pa to Pa up to a hundred can be produced, operation error is relatively large.
Be applied to the burning line and equipment at scene, due to weather and natural calamity, pipe network hidden danger itself, contingency or
The many reasons such as third-party destruction cause fuel gas pipeline leakage event to take place frequently, and most efficient means of speedily carrying out rescue work of repairing are exactly undoubtedly
Band gas welding connects, and downstream user gas had not only been can guarantee that to realize, but also the dual purpose of energy working service operation.Since combustion gas has easily
Combustion, the characteristic such as explosive, gas ductwork operation of not stopping the supple of gas or steam in operation have certain danger.In order to ensure that user's uses gas
Safety, takes the mode of decompression operation under pressure to carry out maintenance.And dangerous big, the safety specifications height of operation under pressure, operation
It must be carried out in strict accordance with act of technique for security, various hazards must be controlled, wherein band gas welding, which connects, belongs to the pneumatic fire of band
Operation, its key point are accurate control pipeline internal pressures, allow the operating pressure at scene to maintain the scope of reasonable benefit/risk.Control
The conventional method of pressure is to carry out manual adjustment, such as selection one or several pressure at the scene by experienced staff
Monitoring point carries out the measurement of pressure using U-tube.Such a operation under pressure mode there are it is obvious the defects of, in this mode of operation
Under, policymaker needs to collect the information that multiple human observers provide, the adjusting aperture of empirically determined valve, and needs real-time
The situation of construction site is solved, and Valve controlling person is indicated.The shortcomings that this method is obvious：
(1) it is more to participate in operation number, the increase of job management difficulty；
(2) commander's effect is poor, and commanding's sense datum is occupied an leading position；
(3) information-based poor in timeliness of transmitting is, it is necessary to which more equipment are serious into row information transmission, a wide range of operation hysteresis quality；
(4) pressure control is unstable, not in time, and risk source control is not in place, and security risk coefficient increases during operation.
The content of the invention
It is contemplated that at least overcome the intelligence that one of drawbacks described above provides a kind of operation under pressure to be depressured monitoring management system,
Pressure among pipeline can be controlled much sooner, exactly.
To reach above-mentioned purpose, what technical scheme was specifically realized in：
One aspect of the present invention provides a kind of intelligence decompression monitoring management system of operation under pressure, including：At least one
A acquisition and analysis instrument, each acquisition and analysis instrument are connected with Urban Pipeline Carrying Natural Gas respectively, and data acquisition is carried out to city gas pipeline；
Band gas construction operation point, band gas construction operation point are connected with least one acquisition and analysis instrument, for receiving at least one collection point
The data of analyzer collection, and send data at least one acquisition and analysis instrument；At least one intelligent gas pressure regulator, each intelligence
Gas pressure regulator, governor is installed on city gas pipeline upstream inlet direction, is connected across the upstream and downstream both ends of main line control valve,
It is connected respectively with band gas construction operation point, and is connected respectively with least one command terminal, for carries out pressure adjusting to main valve；
At least one command terminal, each command terminal are connected with least one acquisition and analysis instrument respectively, for receiving at least one adopt
The data of set analysis instrument collection, and produce control instruction and control at least one acquisition and analysis instrument and/or at least one intelligent gas
Pressure regulator.
In addition, at least one intelligent gas pressure regulator includes two intelligent gas pressure regulators.
In addition, each acquisition and analysis instrument includes wireless transport module, by wireless transport module and with gas construction operation point
It is connected with least one intelligent gas pressure regulator.
In addition, command terminal is PC machine and/or mobile phone.
In addition, intelligent gas pressure regulator includes at least computer chip and display screen.
As seen from the above technical solution provided by the invention, by the system of the present invention, work on the spot people is reduced
The quantity of member, while the link of the data such as manual delivery pressure, flow is eliminated, reduce manual measurement data, manually report
And human error and the time difference caused by linking up, while manual operation is instead of with the Electromechanically integrated numerical control equipment of intelligence, it is real
The real-time Transmission and feedback of data are showed, therefore, have not only largely improved Operation control precision, improve information friendship
Mutual accuracy, while the efficiency and safety coefficient of operation under pressure are also drastically increased, the people has been ensured well
With the safety of public property.
