Description
Technical field
The utility model relates to a kind of optical fiber distributed type heat distribution pipe network monitoring system for monitoring the leakage of heat distribution pipe network body and outside destroy.
Background technique
Heat distribution pipeline is the pipeline of the heat energy such as delivering vapor or superheated water medium.Through urban renewal for many years, heat distribution pipeline many employings underground laying of large-and-medium size cities, comprises in-duct installation and directly buried installation two kinds.Heat distribution pipeline in use can be subject to the effect of high temperature, wearing and tearing, physics, chemistry, in addition the disturbance of periphery underground engineering construction and traffic above-ground dynamic load, the defects such as heat distribution pipeline can crack gradually, be out of shape, joint failure, and then develop accidents such as becoming fracture, leak.If there is pipeline at heating period to leak in a large number even fracture accident, due to heating medium temperature compared with high, pressure is large, flow velocity is fast, the difficulty that often makes to speedily carry out rescue work is large, and hot water is also very large to the harm of other communal facilitys of underground, and loss is difficult to appraisal.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of destruction can damaged because of burn into joint breaking or thermal insulation layer and cause heat distribution pipe network is provided, and the outside of to cause because of processes such as constructions is damaged and is monitored, far measuring distance, can continuous distributed formula measure, accurately can locate, simple optical fiber distributed type heat distribution pipe network monitoring system is installed.
Optical fiber distributed type heat distribution pipe network monitoring system of the present utility model includes the temperature sensing optical fiber and vibration monitoring optical fiber that to walk abreast with heat distribution pipeline and lay; The end of temperature sensing optical fiber be positioned at the DTS sensor (Raman temperature transducer) of monitoring place and be connected, vibration monitoring optical fiber be positioned at the DAS sensor (distribution type fiber-optic sound transducer) of monitoring place and be connected, described DTS sensor is connected 4G network with the collection signal output terminal of DAS sensor through 4G communication module; Also include in system to be connected in 4G network and can receiving sensor send the remote monitoring terminal of signal.
Described remote monitoring terminal includes for showing the display unit of monitoring information and being used for sending the alarm unit of alarm signal.
The utility model by detecting optical cable along heat distribution pipeline parallel laying, the unusual condition Real-Time Monitorings such as pipeline vibration along the line, leakage, heat spot can be realized, there is far measuring distance, continuous distributed formula is measured, can accurately locate, installed the advantages such as simple, safe and reliable, expansivity is strong, any destruction can not be produced on buried pipeline or affect it and normally produce, can identify with de novo leakage part stable, especially be applicable to the application of heat distribution pipeline on-line monitoring.
Accompanying drawing explanation
Fig. 1 is the systematic schematic diagram of the utility model embodiment.
Embodiment
As shown in the figure, this optical fiber distributed type heat distribution pipe network monitoring system includes the parallel temperature sensing optical fiber 2 laid and vibration monitoring optical fiber 3 with heat distribution pipeline 1; The end of temperature sensing optical fiber be positioned at the DTS sensor (Raman temperature transducer) of monitoring place and be connected, vibration monitoring optical fiber be positioned at the DAS sensor (distribution type fiber-optic sound transducer) of monitoring place and be connected, described DTS sensor is connected 4G network with the collection signal output terminal of DAS sensor through 4G communication module; Also include in system to be connected in 4G network and can receiving sensor send the remote monitoring terminal of signal.
Described remote monitoring terminal includes for showing the display unit of monitoring information and being used for sending the alarm unit of alarm signal.
In the utility model embodiment using process, when the tube wall of heat supply pipeline is thinning, after joint breaking or thermal insulation layer damage, can make the temperature anomaly of local pipeline section, temperature sensing optical fiber and DTS sensor can catch these extremely in time, and show on temperature distribution history.By being arranged on can analyzing and the position and the temperature departure that extract abnormity point of remote monitoring terminal, realize warning function.
When Near Pipelines occur that artificial/machinery excavates, vertical and horizontal mechanical boring, large vehicle or machinery above pipeline through etc. likely cause the events such as the machinery excavation destroyed to occur time, earth's surface is subject to an instantaneous excitation, produce seismic waves and distally propagate, vibration signal arrives the vibration monitoring optical fiber of Near Pipelines with propagating, by these oscillating signals of DAS sensor Real-Time Monitoring and by carrying out selection warning to the analysis of signal, and accurate locating events source position.
