Розглянута можливість застосування нелінійних елементів для контролю ушкоджень сегментованих слабострумових кабельних ліній в охоронних системах. Запропоновано метод нелінійної реакції на основі використання стабілітронів встановлених між сегментами контрольованої лінії передачі та вимірювання напруги на вході лінії.
Ключові слова: кабельна система, лінія передачі, нелінійний елемент, стабілітрон, вольтметр.

The use of cable systems is not limited to application within the fields of energy and telecommunications. Wired transmission lines are successfully used in various fields: fire alarm systems, security systems aimed to safeguard objects against unauthorized access, military systems, technological systems, etc. In 80% of cases, the cause of unstable operation or emergency situations of transmission of signals is damage to the cable network. In the context of a global terrorist threat and local military action, the development of new methods of automated technical protection of objects against unauthorized access remains an urgent task. Line control systems can also be used as alarm systems. To lower the cost of the system, the line itself often serves as both a sensor and as an environment for delivering secured information. It is expedient to use the wired perimeter security systems to protect especially important objects by installing the systems in front of the main fence to prevent possible unauthorized entry into the site. Requirements for methods of localization of damage within a cable systems have been developed for application in such systems. According to the requirements, the classification of methods for automatic measurement of damage distances in low-voltage homogeneous transmission lines and promising methods for application in security systems according to criteria of minimization of hardware costs and costs are specified. The method of nonlinear reaction is developed, consisting in measuring the voltage at the inlet of a segmented cable line, which is powered by a direct current with nonlinear elements with a voltage-type characteristic of the limiter installed at the segment junctions. The structural scheme and diagram of the control system for breakage and short circuit breakdowns based on the use of stabilizers as nonlinear elements have been developed. The advantages and disadvantages of using the method of nonlinear reaction in perimeter security systems are indicated, the possibility of simple implementation of the method and variants of its improvement are indicated.
Key words: cable system, transmission line, nonlinear element, Zener diode, voltmeter.
