Description
Technical field
The invention belongs to technical field of electric wires and cables, be specifically related to a kind of intelligent online monitoring railway signal cable.
Background technology
Railway signal cable is applicable to that rated voltage exchanges the control circuit of 500V or direct current 1000V and following transmission railway signal, audio signal or automatic signalling, wherein, composite sheath, aluminium sheath railway signal cable have certain shielding properties, and being suitable for electricly has the area of strong electromagnetic to lay at section or other.
Belong to having of railway signal cable category: railway combined sheath signal cable, railway aluminium sheath signal cable, railway digital signal cable, railway inner shield digital signal cable, railway axle-counting signal cable and railway answering machine data transmission cable, etc.The environment for use temperature of railway signal cable is generally-45～+ 60 ℃, lay ambient temperature and be not less than-10 ℃ usually, the long-term work temperature of cable conductor is no more than 70 ℃, and the core quantity of railway signal cable can reach 61 cores in theory, but is generally about 40 cores.
Technical information about railway signal cable can be seen in disclosed Chinese patent literature in a large number, slightly with exemplify as Granted publication CN2556759Y(railway signal cable), CN202013768U(railway signal cable), the private cable of CN202384093U(rail traffic signal system), CN202677960U(railway signal cable), CN202677879U(novel fire resistant Through ground wire cable) and publication No. CN102800408A(aluminium sheath railway signal cable).
Though the patented technology that is not limited to exemplify above respectively has corresponding strong point, how not stop the moisture invasion and attack to provide corresponding enlightenment to railway signal cable.Application for a patent for invention publication No. CN102136321A recommends to have " moistureproof novel railway signal cable ", this patent sets gradually the lapping layer that blocks water, aluminium-plastic tape moisture-proof layer, polyethylene bonding sheath, steel-tape armouring layer (vertical bag) and polyethylene external sheath layer outside insulated electric conductor, adopt waterstop lapping layer, aluminium-plastic tape moisture-proof layer and petroleum jelly packed layer to embody moisture-proof function; Granted publication CN201845579U provides " antiseepage sections road signal cable blocks water ", this patent has been saved the oil filling paste for CN102136231A, keep off damp screen by waterstop lapping layer and aluminium-plastic tape and make cable have protection against the tide, water stop function.
Undoubtedly, because railway signal cable is laid in underground usually, therefore the situation that namely in use exists moisture and even surface water to infiltrate cable inside under arms unavoidably, then the design of cable with make in take the moistureproof and waterproof measure to have self-evident positive effect.But, no matter have the railway signal cable of moistureproof water stop function or the common cable that does not namely have moistureproof water stop function, in case all can not be known by the railway monitoring system after the invasion and attack of external humidification and even aforesaid surface water namely enter cable core, and only get muddled at the railway network signal, just found after malfunctioning and so on the situation and through a large amount of investigation work.
Hence one can see that, and therefore the railway signal cable in the prior art can not know the information that cable is invaded by water logging owing to have " congenital " defective on the structural design in the very first time.Yet, as described above, if after water inlet in the cable conductor, can not in time dispose as changing, so very might produce rub-out signal, even cause and do not wish to occur but and the railways train operation accident that might occur.
How to make Surveillance center's (custom claim Control Room or control room) of the railway system in time obtain the information that railway signal cable attacked by moisture and/or water enchroachment (invasion) and suffer from industry for a long time, and expectation is solved, but there is no all corresponding technology enlightenments that has in disclosed China and foreign countries' patent and the non-patent literature up to now.
