FIELD: physics.SUBSTANCE: protection section represents structurally complete element. Sensors are arranged vertically on guard web at 20 cm from each other to make zone of sensitivity. Guard post makes a support and doubles as a controller casing. Said controller represents a signal processing unit with built-in radio transmitter and poser supply. Complete set of one section incorporates three guard webs with built-in sensors, post with built-in controller and 12 brackets for attachment of webs to said post. Installation of said guard specifies standard requirements to environments. Said guard is to be installed in definite order. Two posts of adjacent section are fitted in soil of protected object perimetre, fastening guard section webs to posts, addressing of sections, and installation of communication between controller and central station.EFFECT: higher reliability.2 cl, 4 dwg |
