Abstract
The present invention design highlights is the magnetic optical fiber cable sheath having sensing optical fiber, aromatic polyamide fibre filament set between inner sheath and magnetic outer sheath. It is composed of 25-35 per cent neodymium iron boron magnetic particle and 75-65 per cent powdered plastic, through stirring becoming powder plastics having magnetic particle. Said Magnetic optical fiber cable is directly laid and adsorbed structural member and building surface having ferrous material. The inner piece of said optical fiber cable I s parallel each other, uncrossed, stressing uniformly, reducing optical fiber cable generated internal stress, thereby effectively releasing sensing fiber-optic stressing.
Description
Technical field
The present invention relates to the auxiliary equipment field of information transmission and sensor information.Particularly, be to disclose a kind of optical cable and this optical cable thereof that has magnetic to adopt how method is made.The optical cable that has magnetic can rely on the magnetic force that itself possesses, and is adsorbed on the structural member that has ferrous material to be laid, buildings, bridge, oil tank etc. easily and locates, and uses as sensor.
Background technology
Along with developing rapidly of China's sensing cause, monitor the temperature and the seepage phenomenon of buildings, installations and facilities with optical fiber as sensor, more and more paid attention to by people.When laying, the mobile failure that causes monitoring result of optical cable is afterwards laid in the location of optical cable and fixing very important to optical cable as sensor.Therefore, optical cable needs constantly optical cable to be fixed in process of deployment, and bed knife is moderate.Bed knife is crossed senior general and is caused consume of optical cable inner fiber or damage, influences monitoring accuracy, even can not monitor; Bed knife is too small, and optical cable produces and moves or displacement; And fixedly the workload of optical cable is quite big, requires also than higher, and the fixture consume is also very big.In some cases, fixedly optical cable will cause the damage of monitored thing, and the monitored thing that has (as the iron structure body) mounting fixing parts of having no idea so just must influence the application and the popularization of this class high-tech product.The ZL patent No. 03232344.1 is a kind of novel cable configuration.It comprises the information transmission medium that serves as by simple optical fiber or by the fibre bundle that simple optical fiber set forms and is coated on sheath on the information transmission medium, it is characterized in that also being coated with in the described sheath stress load bearing component and the stress discrete part of extending in the same way with information transmission medium.Each parts of this optical cable are parallel mutually, do not intersect, and are stressed even, reduce the internal stress that optical cable self is produced; Thereby effectively alleviate the stressed of optical fiber, guarantee its information transmission performance.But do not disclose the optical cable that has magnetic as yet.
Summary of the invention
The present invention will overcome the deficiency of known technology, provide a kind of magnetic optical cable and manufacture method thereof to this area.Make it will solve the technical matters of above-mentioned existence.The objective of the invention is to realize by the following technical solutions.
A kind of magnetic optical cable, this magnetic optical cable comprise oversheath, aramid fiber silk, inner sheath, sensor fibre, it is characterized in that being provided with in the inner sheath sensor fibre, are provided with the aramid fiber silk between inner sheath and the oversheath, and described oversheath has magnetic.
Described magnetic optical cable comprises single sensor fibre or at least two sensor fibres, and disposes corresponding inner sheath, aramid fiber silk, oversheath.
A kind of magnetic optical cable manufacture method, it is characterized in that oversheath is made up of NdFeB magnetic powder and powdered plastic, wherein the weight ratio of NdFeB magnetic powder is 25～35%, and the weight ratio of powdered plastic is 75～65%, becomes the powdered plastic that has magnetic through stirring to mediate.
Be added with content inorganic filling such as lime carbonate in the described compound, fire retardant such as Firebrake ZB, antioxidant such as β-positive ten caprylates of (3.5-di-tert-butyl-hydroxy phenyl) propionic acid.
Described inner sheath and sensor fibre are inner sheath optical fiber by extruder extrusion molding, cooling, reel.
Described inner sheath optical fiber and aramid fiber silk, the powdered plastic that has a magnetic are optical cable through extruder extrusion molding, cooling, reel, and optical cable magnetizes through magnet charger again, makes magnetic optical cable.
The described magnet charger time of magnetizing is 5～10s, magnetic flux 〉=600 Gausses.
The present invention has ferromagnetism, be laid immediately on the structural member, buildings, bridge, the oil tank place that have ferrous material, utilize the magnetic force of optical cable own, firmly be adsorbed on the surface of these members, and replacing is very convenient to another adsorption plane, as long as the optical cable of adsorption plane is drawn back laying again.Outside ferrous material, will be as general sensor application.
Each parts of this magnetic optical cable are parallel mutually, do not intersect, and are stressed even, reduce the internal stress that optical cable self is produced; Thereby effectively alleviate the stressed of optical fiber, guarantee its information transmission performance.
