Description
Technical field
This utility model relate to underground pipe gallery (being also referred to simply as pipe gallery, underground pipe gallery or piping lane) and
The status monitoring field of affiliated facility (including and be not limited to pipeline, cable, optical cable, power equipment).
Background technology
Underground pipe gallery is exactly the comprehensive corridor of underground urban duct.I.e. build a tunnel sky at Urban Underground
Between, by electric power, communication, the various utilities pipelines such as combustion gas, heat supply, plumbing are integrated in one, and are provided with special
Access hole, hoisting port and monitoring system, implement unified planning, Uniting, unified build and management,
It is important infrastructure and " life line " ensureing city operations.By by 2016, the buried pipe of China
Corridor construction is scarcely out of swaddling-clothes.The most also do not have a kind of monitoring method can comprehensive, real-time and precise right
Underground pipe gallery and affiliated facility carry out operation state monitoring.When underground pipe gallery and affiliated facility run into underground pipe gallery
Internal cable or electric power facility heating gas pipeline breakage within spontaneous combustion, underground pipe gallery cause gas leakage
When occurring etc. situation, if early warning accurately in time and accident location cannot be accomplished, in underground pipe gallery being caused
Portion's water logging, on fire, underground pipe gallery building structure destruction, affiliated facility infringement, so affect communication, water supply,
Draining, the normal operation of supply work, or the work safety accident exploding, polluting.Therefore, need badly
A kind of operation state that can promptly and accurately monitor underground pipe gallery and affiliated facility, thus accident early warning is positioned
Piping lane cable status and gas concentration monitoring system.
Utility model content
The purpose of this utility model is to propose a kind of underground pipe gallery and affiliated facility are carried out status monitoring to combine
Close monitoring system.Thus corresponding accident is given warning in advance and localized accident position, for operation monitoring, meet an urgent need
Repairing work provides technology and data supporting.
For reaching this purpose, this utility model by the following technical solutions:
A kind of piping lane cable status and gas concentration monitoring system, it includes data center and data acquisition demodulation
Instrument；Described data acquisition (FBG) demodulator is connected with described data center communication；This piping lane cable status is dense with gas
Degree monitoring system also includes inside the cable status monitoring modular that is connected with described data acquisition (FBG) demodulator and piping lane
Monitoring harmful gases module.
Further, described cable status monitoring modular includes the distribution being connected with described data acquisition (FBG) demodulator
Formula fibre optic temperature sensor and distributed optical fiber vibration sensor.
Further, the internal monitoring harmful gases module of described piping lane includes with described data acquisition (FBG) demodulator even
The fiber-optic grating sensor connect.
Further, this piping lane cable status and gas concentration monitoring system also include one with described data center
The command centre that communication connects, described command centre has display screen.
The beneficial effects of the utility model are:
Fill up the blank of domestic underground pipe gallery comprehensive state monitoring system.Compared with traditional single monitoring system,
Can monitor simultaneously and detect temperature and the multiple state of gas concentration of underground pipe gallery.Than traditional manual inspection
Measuring, the method for Pressure gauge and effusion meter statistical data is more advanced, more practical, more accurately, more comprehensively.?
Cable status monitoring aspect, can be with the variations in temperature of monitoring power cable.When local occurs that temperature is too high or acute
Early warning the elements of a fix are carried out, it is to avoid because local temperature is too high or dramatic temperature change causes during strong variations in temperature
Fire.In terms of monitoring harmful gases, can within underground pipe gallery specific gas (as methane, one
Carbonoxide) concentration is monitored.When gas concentration reaches calibration value alarm, it is to avoid because harmful gas is dense
Spend height cause personnel to injure, the accident such as blast.
Accompanying drawing explanation
Fig. 1 is the overall structure figure of this utility model piping lane cable status and gas concentration monitoring system；
Fig. 2 is the attachment structure figure between cable status monitoring modular and data acquisition (FBG) demodulator；
Fig. 3 is the attachment structure figure between the internal monitoring harmful gases module of piping lane and data acquisition (FBG) demodulator.
Detailed description of the invention
For making this utility model solve the technical problem that, the technical scheme that uses and the technique effect that reaches more
Clear, it is described in detail as follows in conjunction with the drawings and specific embodiments:
Refer to Fig. 1, a kind of piping lane cable status that this utility model provides and gas concentration monitoring system, its
It is characterised by, including data center and data acquisition (FBG) demodulator；Described data acquisition (FBG) demodulator and described data
Center communication connects；This piping lane cable status and gas concentration monitoring system also include and described data acquisition collected explanations or commentaries
Adjust cable status monitoring modular and the internal monitoring harmful gases module of piping lane of instrument connection.Additionally, this piping lane electricity
Cable state also includes a command centre being connected with described data center communication, institute with gas concentration monitoring system
State command centre and there is display screen, so can realize the display to part significant data and early warning.
Cable status monitoring modular and the internal monitoring harmful gases module of piping lane is introduced below in conjunction with accompanying drawing.
Seeing Fig. 2, cable status monitoring modular includes distributed optical fiber temperature sensor and distributed optical fiber vibration
Sensor.When there is abnormal vibrations in the cable installation within underground pipe gallery or local pyrexia temperature is too high, point
Cloth fibre optic temperature sensor and distributed optical fiber vibration sensor can monitor temperature and vibration change and gather
Data are uploaded to data center, give warning in advance and position, and support that maintainer arrives accident spot in time, keep away
Exempt from the too high breaking out of fire of cable temperature and supply of electric power is interrupted.
