Description
Technical field
The present invention relates to a kind of intruder detection system.
Background technology
Intruder detection system is the apparatus system forming for detecting intrusion person's movement or the electronics of other actions and mechanical part, and detected object comprises infrared ray, microwave, ultrasound wave, vibration, sound equipment etc.
Each intruder detection system all has surveys certain means that discrepancy person exists in security zone, and the parts of carrying out this task in device are called detector or sensor.Desirable intruder detection system is the existence of response personnel only, and does not respond as the activity of the animals such as dog, cat and mouse, does not also respond the variation of indoor environment, as the sound of the variation of temperature, humidity and wind, rain and vibration etc.Accomplish that this point is not easy to, most of devices have not only responded people's existence, and. the impact of some irrelevant factors is also produced to response.To the selection of alarm and installation, also will consider it is not responded irrelevant factor, the repeatability of synchronous signal will be got well.The warning of sending while there is no intrusion behavior is wrong report.Wrong report may cause due to element fault or some ectocine, and the lightest consequence is because having increased many unnecessary troubles, people to be fed up with, thereby greatly reduces the confidence level of alarm.It is contemplated that, if shop and store management personnel have often been cried from the bed due to wrong report, they just can not be ready to use this warning device.The worst consequence is that it is on the scene police or security personnel unnecessaryly at top speed, like this they safety itself and around people's safety all can be endangered.Therefore, wrong report is the deadly defect of alarm.
Because department's situations separately such as family, shop, group and enterprise are different, the intruder detection system of use is also not quite similar.In order to obtain best security personnel's effect, conventionally need to carry out cutting to warning system according to user's actual conditions, just can make like this detector play a role better.
The invention provides a kind of intruder detection system that embedded fiber acquisition sensor and wire netting are combined, when invader acts on strength on fence bar and is greater than default threshold value or crooked fence stripe pitch and surpasses default threshold value, trigger accordingly and report to the police.Due within sensor is placed in roll guard, so performance is more stable, be not easy to be subject to the impact of the environmental factors such as strong wind, sleet, electromagnetism and external disturbance, in addition, due to this system, utilize acting force and deformation on fence bar and carry out monitoring, alarming, be not subject in any water impact vibrations, water the caused vibration effects such as foreign material shock, the vibrations of culvert current echo and trigger false alarm.

Embodiment
Fig. 1 shows the schematic diagram according to intruder detection system of the present invention.Intruder detection system according to the present invention comprises: system control device, sensor, optical fiber, dry contact control unit and Control Server, system control device is for detection of the signal loss returning on described optical fiber, sensor is used for the stressed decay that is converted to light signal in outside, optical fiber is for being looped back to system control device by light signal, dry contact control unit is used for controlling external prompting device, when system control device detects signal loss and is greater than default threshold value, the alarm of indication dry contact control unit triggers, dry contact control unit controls external prompting device is sent alerting signal.Anti-trimming, through fence montant, also can trigger alarm when user cuts off montant.
Fig. 2 shows the schematic diagram of the sensor that intruder detection system according to the present invention uses.Fig. 3 shows the schematic diagram below of sensor lower house; Fig. 4 shows the wiring layout of main part and annex in sensor upper shell; Fig. 5 shows the schematic diagram of annex in sensor upper shell.Fig. 2 can find out in Fig. 5, and in a preferred embodiment of the invention, the sensor that intruder detection system uses comprises upper shell, lower house, optical fiber indent and spring.Optical fiber indent and spring fitting are at sensor internal, and optical fiber indent is used for burying underground optical fiber, and spring is for making sensor have certain holding capacity and can be used in the critical force value that regulates sensor.In the embodiment shown in fig. 1, sensor outside is also equipped with bracket, is convenient to installation of sensors under the girder steel of fence bar.
Spring guide and spring guide pillar are used for placing spring.When thereby upper shell and lower house are subject to external force extruding compressing and are placed in the optical fiber of optical fiber indent; if external force surpasses switch pre set force value; seam and spring guide pillar by upper shell and lower house bear strength; rather than born by spring and optical fiber; thereby protection spring and optical fiber are not damaged, and can make the accommodation of switch wider.Spring after installation has precompression, thereby make sensor there is pre-holding capacity, even if bearing certain strength, initial installation also can make each parts keep conventional state, external force disappearance rear spring screen resilience automatically resets upper shell and lower house, optical fiber reverts to straightened condition, light signal strength is without attenuation, and switch is got back to normal condition.According to sensor of the present invention, can, so that single anti-section length is longer, in addition, by changing the hardness of spring, can regulate the critical force value of sensor.
Sensor has closure designs on the whole, can prevent that dust from affecting between upper shell and lower house is subjected to displacement, does not bear a little as lower limit strength upper-lower casing seam outer, when being subject to external force to reach switch closed condition, seam outer still remains with gap, prevent that extraneous dust from accumulating on seam, affect switch and arrive closure state.In a preferred embodiment, lower house bottom is provided with osculum and the husky hole of spoil disposal, for draining and discharge silt, thereby thereby avoids being obstructed because lower casing cylinder accumulation water or silt cause upper shell to move down.Upper shell comprises main part and annex, and annex can be dismantled, and conveniently optical fiber is embedded in optical fiber indent.
Fig. 6 shows according to the assembling schematic diagram of sensor in intruder detection system of the present invention.As can be seen from the figure, sensor engages with the girder steel on fence bar by bracket, and optical fiber is connected to the system control device of intruder detection system to optical fiber attenuation is detected to judgement by optical fiber indent through sensor.
According to the principle of work of intruder detection system of the present invention, be: climbing causes on fence bar and produces downward acting force, by a girder steel through all fence bars, power is passed to the upper-lower casing to sensor.Because installation of sensors is in inside, fence outside does not have whatever, attractive in appearance and hidden, is not easy destroyed.Want outer vibrations optical fiber, vibrations cable or the sensor hanging on fence to realize with other intruder detection system and compare, sensor of the present invention can be kept away and be damaged and external interference.
It will be understood by those of skill in the art that above-described embodiment is only for exemplarily making an explanation to the present invention, protection scope of the present invention is defined by claims, is not limited in above specific embodiment.Those of ordinary skill can carry out various modifications to above-mentioned specific embodiment, and amended technical scheme falls into protection scope of the present invention equally.
