Zusammenfassung: | The invention relates to a capacitive sensor system for perimeter protection devices, which system can be easily built into walls and other perimeter protection devices, where it can go unnoticed and remain insulated from adverse weather conditions. For this purpose, the system is formed by two basic elements, namely: a sensor element (1) in the form of a flexible capacitor with reduced thickness but increased length, intended to be camouflaged in the surface of the rigid barrier and a control electronics module for measuring variations in the capacitance of the sensor element by means of an integrator (13) connected to said element and associated with a microcontroller (12) which records any possible variations. The device can be used to monitor different pressure levels for the sensor, thereby preventing the triggering of false alarms.
Sistema sensor capacitivo para dispositivos de protección perimetral.El sistema de la invención es fácilmente integrable en muros y otros dispositivos de protección perimetral permaneciendo inadvertido y aislado de condiciones meteorológicas adversas. Para ello, el sistema que se preconiza está constituido a partir de dos elementos fundamentales, un elemento sensor (1), materializado en un capacitor flexible de espesor reducido pero de elevada longitud, destinado a integrarse de forma camuflada en la superficie de la valla rígida, y un módulo de electrónica de control, que se encarga de medir las variaciones de capacidad del elemento sensor a través un integrador (13) conectado dicho elemento y asociado a un microcontrolador (12) que registra dichas posibles variaciones.El dispositivo así descrito permite monitorizar diferentes niveles de presión para el sensor, lo que permite a su vez evitar el disparo de falsas alarmas. |
