The utility model principle of work: be divided into 4 defence areas according to actual needs, each anti-section length is determined according to actual conditions.The part of enclosure wall adopts the mode of button net to lay, and between adjacent two defence areas, uses optics Module Division.Alarm host machine (connecting wind and rain gauging ring), keyboard are located at room on duty, and when there is invasion, optical cable is vibrated, and produce invasion signal and pass to alarm host machine, by alarm host machine, send alerting signal.
The utlity model has following beneficial effect: it adopts optical cable as sensor measuring unit, and its linear structure is not subject to the restriction of peripheral profile, and warning precision is high.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model vibration wireline laying structure schematic diagram.
Embodiment:
Referring to Fig. 1-2, this embodiment is by the following technical solutions: it comprises optic cable vibration and surveys main frame 1, wind and rain vibration detecting ring 2, interlocking main machine 3, optical module 4, alarm 5, master keyboard 6, vibration optical cable 7, button net 8, described wind and rain vibration detecting ring 2 is surveyed main frame 1 with optic cable vibration and is connected, interlocking main machine 3 is surveyed main frame 1 respectively at optic cable vibration and is connected with alarm 5, master keyboard 6 is surveyed main frame 1 with optic cable vibration and is connected, optical module 4 is surveyed main frame 1 with optic cable vibration and is connected, vibration optical cable 7 is connected with optical module 4, button net 8 is connected with vibration optical cable 7.
Described vibration optical cable 7 parts are laid on the upper end of periphery body of wall and carry out snapping and fix by buckleing net 8, and another part vibration optical cable 7 is embedded in exterior surface of wall inside.
Optic cable vibration is surveyed main frame 1 and is adopted the large-scale bus alarm host machine that model is HY-ZJ-A4, adopts pure hardware Embedded System Design, 32 ARM7 processors, 16K RAM, 64K FLASH; Possess 4 defence areas and expand independently RS232 communication port of 485 bus interface and; Carry 16 defence areas, can expand 62 dissimilar modules by 485 buses, have 16 kinds of bus enlargement module types available; Superpower episodic memory ability, records the most de novo 2944 events automatically in detail, can be read and be consulted by keyboard or management software.
Optical module 4 models are HY-ZJ-AJX32, shell and photoreactivation device, optical-path interface, consist of, and are mainly used in the protection to optical device such as cable connection, light signal conversions.The shell employing engineering plastics making that sensing optic cable continues and wraps, is installed on outdoor environment, can adapt to various severe physical environments, and have waterproof sealing performance.
Wind and rain gauging ring 2 models are HY-ZJ-AFY2012, adopt special equivalent technical finesse, when blowing, raining, automatically automatically adjust with the contrast of all defence areas, contrary, when bright day gas occurs, wind and rain gauging ring is got back to original state automatically, and object is to reduce wrong report to fail to report phenomenon.Without manual operation, greatly reduce human resources.Improve circumference report theft system security, preparatory.Wind and rain gauging ring is connected separately with vibration optical cable alarm host machine by optical cable, and method of attachment is identical with defence area, draws one output to the stainless steel frame of wind and rain gauging ring to outdoor roof without sensing optical cable from main frame.
Vibration optical cable 7 adopts GYXTW-6B1 single mode armored optical cable, can the vibration signal of inductive action on optical cable, vibration signal is converted to the optical physics amount of variation, as light intensity, partially shake state, deflection angle, optical signal frequency etc., and by the optical signal transmission of the implicit above physical characteristics changing to vibrating in optical cable alarm host machine.Owing to having used optical cable as sensing unit, the factors such as extraneous strong-electromagnetic field, thunder and lightning can not exert an influence to system, and optical cable has, and cost is low, uvioresistant, anti-aging, applicable to features such as irregular circumferences, be applicable on a large scale very much, grow distance, the severe field circumference environment of environmental baseline.
Optical cable laying method:
Enclosure wall is crossed in strick precaution:
If invader adopts the mode of crossing to enter, the vibrations that produce in this process are extremely faint, and the signal that vibrations optical cable senses is not enough to the foundation as judgement invasion, so while taking precautions against this invasion mode, must be on the top of a wall installing tache net, to increase intensity and the induction area of vibrations.It is the iron net of 5cm X 5cm that button net materials generally adopts Φ 5, aperture.When the online fixing vibrations optical cable of button, should note vibrations optical cable to be fixed on the top that net is buckled in enclosure wall outside.When improving warning rank, needs optical cable laying can be become to undaform.
Take precautions against cutter wall:
Cutter wall is a kind of common invasion mode for enclosure wall, and vibrations optical cable can detect the small vibrations that produce when invader cuts a hole wall.Workmen can adopt parallel line type mode on metope, to lay twice optical cable, the height of enclosure wall should be over 2 meters, optical cable should be fixed on apart from 0.6 meter, ground and 1.6 meters of, if enclosure wall height is greater than 2 meters, highly every increase is 1 meter, needing increases by one optical cable, and optical cable is horizontally fixed on the middle part in this region.In order to guarantee to shake the vibrations that produce when optical cable can sense cutter wall, must guarantee that metope is solid, fragment of brick can not have loosening, and optical cable should closely be attached to enclosure wall surface.Can use wire clip to be fixed every 50 centimetres.
This embodiment has following beneficial effect: it adopts optical cable as sensor measuring unit, and its linear structure is not subject to the restriction of peripheral profile, and warning precision is high.
