RADIO PROTECTION SYSTEM WITH PATROL VEHICLES Russian patent published in 2004 - IPC

FIELD: technology for protection of extensive objects like main oil pipelines.

SUBSTANCE: system includes stationary devices for alarm signaling in points with known coordinates, and end object devices. Also provided are worn end object devices and information processing center provided with control panel end device and connected to dispatching center, connected via long range communications system to patrol vehicles. Data transfer network includes relay stations. Stationary object end devices receive messages from worn object end devices and relay them through other stationary object end devices and/or relay station to control panel end device in information processing center. When protecting an extensive object, worn object end devices are mounted on patrol vehicles moving along protected object, and stationary devices for alarm signaling and relay stations are placed along all length of object to provide chain relay to code message center from alarm systems, which detect unsanctioned action against the object, and also from relay stations and/or stationary object end devices receiving messages from carried object end devices.

EFFECT: simplified construction, lower operation and maintenance costs.
