Description

Pipe safety operation real-time monitoring system

Technical field

The utility model relates to pressure piping safe operation real-time monitoring system, is specifically related to be used for combustion gas etc. and utilizes pressure to monitor the device of pipeline operation conditions, belongs to automated security monitor and reports to the police and the on-line operation administrative skill.

Background technique

Under ground piping in rock gas, oil, water and the various urban construction because of service time permanent burn into breakage or the caused incident of leakage of construction wrong more and more outstanding; The lighter is leaked and to be caused the wasting of resources and environmental pollution, and is heavy then cause and catch fire, even explodes, and causes immeasurable economic loss thus.In the prior art, usually adopt the artificial way of detection regularly the under ground piping in rock gas, oil, water and the various urban construction to be detected or safeguard, but can not solve sudden and pipe leakage Unpredictability, particularly geological environment changes, as sedimentation under the spot, or weight infringement that pipe damage is brought.Chinese patent 200620110767.0 disclosed " line leakage positioning alarm system " has solved the problems referred to above.But because unbalanced with (combustion gas) amount, each sub-district is terminal use inconsistent owing to the peak period gas consumption particularly, causes some user " feeble " to influence work and life in the zone; And the staff of control system can not understand terminal use's pressure and flow situation easily in real time, need each terminal use's phone reaction, staff by control system makes suitable adjustment according to actual needs again, turn off some no terminal uses with block valve, suitably adjust the big terminal use's of gas consumption discharge pressure, to solve the problem of usefulness gas difficulty.Not only time-consuming, the effort of present this monitoring method, accurate not enough.

The model utility content

At the prior art above shortcomings, the purpose of this utility model is to provide a kind of not only can monitor pipe leakage in real time, can also move real-time monitoring system to the pipe safety that terminal use's pressure and traffic conditions are carried out monitoring management.

The purpose of this utility model is achieved in that pipe safety operation real-time monitoring system, the control system and the pressure acquisition sensor that comprise the line transportation control end, control system is used to control each user terminal gate valve, and receives the information of processing pressure acquisition sensor; The pressure acquisition sensor is located at the tee union place, any joint two ends (on the standby plug) of conveyance conduit, and the pressure acquisition sensor is directly experienced internal pipe pressure and linked to each other with control system by the mission controller that is attached thereto; Some user terminal gate valves place is provided with pressure transducer, and the output signal of pressure transducer is connected with control system by mission controller; The controller of control system is connected with the urgency stop controller of pipeline user terminal gate valve.

Some user terminal gate valves place of pipeline also is provided with flow transducer, and the output signal of flow transducer is connected with control system by mission controller.

Pressure transducer, flow transducer and the mission controller that the utility model uses can be installed dryelement cell and use, and be not only safe and reliable but also cost is low.

The related data that adopts the utility model can in time gather pressure and flow, for management system to each sub-district carry out peak regulation with the gas situation, guarantee that each community user evenly uses gas, effectively improve the level of scientific management; Can also carry out the remote flow meter amount to the consumption of each sub-district in netting, the grasp terminal use consumes situation and adjusts, labor intensity of checking meter in the scene of reducing to and time, the resource that can use manpower and material resources sparingly in a large number in management so fully reduces network management operating cost; System's regulator to supplying gas and close and handle in the network, and can promptly block the strick precaution potential safety hazard by urgent block valve when potential safety hazard appears in pipeline, thereby guarantees science, Security and the validity of the network operation, stops potential safety hazard; And the utility model to need not personnel on duty, this device is particularly useful for having the gas of certain pressure, the under ground piping that liquid is carried.It has advantage simple in structure, that cost is low, convenience is managed and used.

Embodiment

As shown in Figure 1, pipe safety moves real-time monitoring system, comprises the control system 1 and the pressure acquisition sensor 2 of line transportation control end, and control system 1 is mainly used in each user terminal gate valve 3 of control, and receives the information of processing pressure acquisition sensor 2; Pressure acquisition sensor 2 is located at the tee union place, any joint two ends (on the standby plug) of conveyance conduit, and pressure acquisition sensor 2 is directly experienced internal pipe pressure and linked to each other with control system 1 by the mission controller 4 that is attached thereto; Some user terminal gate valves 3 places of pipeline are provided with pressure transducer 5, and the output signal of pressure transducer 5 is connected with control system 1 by mission controller 6; The controller of control system 1 is connected with the urgency stop controller of pipeline user terminal gate valve 3.

More perfect system is that some user terminal gate valves 3 places of pipeline also are provided with flow transducer 7, the output signal of flow transducer 7 is connected with control system 1 by mission controller 8, can make control system grasp in the net in real time and each terminal use's consumption situation, the labor intensity of checking meter in the scene of reducing to.

Mission controller
