Description
技术领域 technical field
本实用新型涉及一种电缆，尤其是配套入侵探测装置的泄漏感应同轴电缆。The utility model relates to a cable, in particular to a leakage induction coaxial cable matched with an intrusion detection device.
背景技术 Background technique
现有的安保系统主要是电视摄像监控系统和红外感应传感系统两种方式；它们的缺点，一是投资大，运行成本高；如电视摄像监控需要在各个关键部位安装多个摄像头，需要人员24小时不间断监视图象；二是设备特征明显，极易暴露目标；人们只需稍加注意就能发现摄像头或者红外探测头，从而给不良企图者制造回避或毁损的机会。The existing security systems are mainly two methods of TV camera monitoring system and infrared induction sensor system; their disadvantages are that the investment is large and the operating cost is high; for example, TV camera monitoring needs to install multiple cameras in various key parts, requiring personnel 24-hour uninterrupted monitoring of images; second, the equipment has obvious features, which are very easy to expose the target; people only need to pay a little attention to find the camera or infrared detection head, thus creating opportunities for bad intentions to avoid or damage.
另一方面，常规的电缆主要用于输送电流或电子信号流；其一般的构造是在导体材料制作的芯线外依次包敷绝缘层、屏蔽层和外皮。On the other hand, a conventional cable is mainly used to transmit electric current or electronic signal flow; its general structure is that an insulating layer, a shielding layer and an outer sheath are sequentially coated on the outside of the core wire made of conductive material.
实用新型内容 Utility model content
本实用新型所要解决的技术问题是克服上述背景技术的不足，提供一种安保监测装置的关键部件，使得所构成的安保监测装置具有灵敏度高、隐蔽性强的特点；并且成本不高。The technical problem to be solved by the utility model is to overcome the disadvantages of the above-mentioned background technology and provide a key component of a security monitoring device, so that the security monitoring device has the characteristics of high sensitivity and strong concealment; and the cost is not high.
本实用新型采用的技术方案是：The technical scheme that the utility model adopts is:
泄漏感应同轴电缆，具有导体材料制作的芯线，该芯线外部依次同轴包敷绝缘层、屏蔽层和外皮，所述的屏蔽层制有规则或不规则分布的一组开口，以使芯线通过电流时产生的磁场能够泄漏出来在电缆周围形成设定的探测磁场。The leakage induction coaxial cable has a core wire made of conductive material, and the outside of the core wire is coaxially covered with an insulating layer, a shielding layer and an outer sheath in sequence, and the shielding layer is made with a group of openings distributed regularly or irregularly so that The magnetic field generated when the core wire passes through the current can leak out to form a set detection magnetic field around the cable.
所述的屏蔽层用铜箔带绕制而成。The shielding layer is made of copper foil tape.
所述的铜箔带外还用一层塑料薄膜包敷扎紧。The outside of the copper foil strip is wrapped and tied tightly with a layer of plastic film.
本实用新型的工作原理是：两根泄漏感应同轴电缆间隔一定距离埋入地面下或隐蔽部位，其中一根泄漏感应同轴电缆接通泄漏电缆探测器的发射单元；发射单元产生的高频电能馈入泄漏感应同轴电缆，并在电缆中传输；当电能沿电缆传送时，产生的磁场通过泄漏电缆屏蔽层的开口漏入空间，在被警戒空间范围内建立电磁场，其中一部分电磁场被安装在附近的另一根泄漏电缆接收，形成收发电磁能量直接耦合。当入侵者进入两根电缆形成的感应区内时，这部分电磁能量受到扰动，引起接收信号的变化，这个变化的信号被基于PC机的中央管理系统检测出来并进行放大处理后，启动报警装置。The working principle of the utility model is: two leakage induction coaxial cables are buried under the ground or in a concealed position at a certain distance, and one of the leakage induction coaxial cables is connected to the emission unit of the leakage cable detector; the high frequency generated by the emission unit Electric energy is fed into the leakage induction coaxial cable and transmitted in the cable; when the electric energy is transmitted along the cable, the generated magnetic field leaks into the space through the opening of the leakage cable shielding layer, and an electromagnetic field is established within the range of the guarded space, and a part of the electromagnetic field is installed It is received by another leaky cable nearby, forming a direct coupling of transmitting and receiving electromagnetic energy. When an intruder enters the sensing area formed by the two cables, this part of the electromagnetic energy is disturbed, causing a change in the received signal, which is detected by the PC-based central management system and amplified to activate the alarm device .
本实用新型的有益效果是：由泄漏感应同轴电缆配套构成的安保探测装置隐蔽性强，感应电缆安装后不影响整个建筑物的美观，且探测场不可见，所以入侵者感觉不到埋地式感应电缆的存在，且不知具体位置，更没法绕过或破坏；因而具有显著的安保效果。此外，该电缆的结构较为简单，生产工艺与现有的电缆类似，所以成本也不高。The beneficial effects of the utility model are: the security detection device formed by the leakage induction coaxial cable is highly concealed, the installation of the induction cable does not affect the appearance of the whole building, and the detection field is invisible, so the intruder cannot feel that it is buried in the ground The existence of the type induction cable, and the specific location is unknown, and it cannot be bypassed or destroyed; therefore, it has a significant security effect. In addition, the structure of the cable is relatively simple, and the production process is similar to the existing cables, so the cost is not high.

具体实施方式 Detailed ways
泄漏感应同轴电缆，具有导体材料制作的芯线1，该芯线外部依次同轴包敷绝缘层2(通常用聚乙烯之类的塑料)、屏蔽层3和外皮5；所述的屏蔽层制有规则或不规则分布的一组开口3-1，以使芯线通过电流时产生的磁场能够泄漏出来在电缆周围形成设定的探测磁场。该开口的大小、形状、数量以及开口之间的距离都可根据需要确定。Leakage induction coaxial cable has a core wire 1 made of conductive material, and the outside of the core wire is coaxially coated with an insulating layer 2 (usually plastic such as polyethylene), a shielding layer 3 and an outer sheath 5; the shielding layer A group of openings 3-1 are made with regular or irregular distribution, so that the magnetic field generated when the core wire passes current can leak out to form a set detection magnetic field around the cable. The size, shape, quantity and distance between the openings can be determined as required.
所述的屏蔽层采用铜箔带绕制而成，绕制时特意留出所述的开口；铜箔带外还用一层塑料薄膜包敷扎紧(图中塑料薄膜省略)，以利于最外层外皮的顺利包敷成型。The shielding layer is made of copper foil tape, and the opening is deliberately reserved when winding; the copper foil tape is also wrapped with a layer of plastic film (the plastic film is omitted in the figure) to facilitate the best Smooth overmolding of the outer skin.
本实用新型作为一种隐蔽的安保探测传感器，用其配套构成的安保探测装置所产生的电磁场是一种大的空间场，能够对移动目标的导电性、体积、移动速度进行探测；人或车通过该电磁场都会被探测到，而小动物或鸟类却不会引起报警，并可以滤除环境的影响，如植被、雨、雪、风沙等；并且该安保探测装置由于不易察觉以及不容易被破坏的特点，因此具有广阔的市场前景。The utility model is used as a concealed security detection sensor, and the electromagnetic field generated by its supporting security detection device is a large space field, which can detect the conductivity, volume and moving speed of the moving target; It will be detected through the electromagnetic field, but small animals or birds will not cause alarms, and can filter out environmental influences, such as vegetation, rain, snow, wind and sand, etc.; The characteristics of destruction, so it has a broad market prospect.
