Abstract
This paper presents tests of the active composite fence with razor tape module. Due to application of electro-magnetic and optical fiber sensors the fence becomes actively protected. This type of solution may be used to detect violations of peripheral areas [1]. Due to using composite materials the fence is lighter, cheaper and resistant to environmental conditions (including corrosion). What is the most important the composite fence system is transparent to electromagnetic waves. Another advantage of using composite material is the possibility of integration the fiber optic and electro-magnetic cable in the structure of the fence [2]. The durability of a composite is comparable to a standard metal fence. The paper presents test results of the sensors placed on the composite fence. This type of the fence system protection with alarm sensors integrated in its structure is unique in the world scale. Performed tests consisted of laboratory and field tests of modalmetric fiber optic sensor itself, laboratory and field tests of electro-magnetic sensor itself and field tests of both sensors combined. During the laboratory tests an electrodynamic shaker was used to excite the modalmetric sensor to an alarm state. Its excitation distance decreases with the frequency growth. The tests were made for different frequencies and different forces to imitate different fence violation e.g. climbing on it, cutting it or walking along it.
