Security device and system for monitoring pipes
First Claim
1. Safety device for a covering device (2) of a pipe and for a pipe, which can be used with a row of further pipes in a form welded to one another for producing pipelines, wherein the covering device (2) covers one end of the pipe and comprises a sleeve (5) inserted into the pipe and covering an inner wall of the pipe, wherein the safety device (1) is embodied to generate an alarm signal, wherein the safety device (1) comprises a structure-borne sound detection device comprising a structure-borne noise sensor (38) for detecting tampering with the pipe by sensing noise resulting from tampering, wherein the structure-borne noise sensor (38) is arranged on the sleeve inside the pipe and contacts the inner wall of the pipe.

Abstract
The invention relates to a security device for a cover device of a pipe and/or for a pipe, that can be used for producing pipelines having a series of further pipes welded to each other, wherein the cover device comprises a sleeve covering an inner wall of the pipe, and the security device is designed for generating an alarm signal, wherein the security device comprises a structure-borne sound detection device comprising a structure-borne sound sensor for detecting manipulation of the pipe. The invention further relates to a system for monitoring pipes having a plurality of security devices having a receiving station for receiving the security device signals, preferably repeatable by means of a repeater, and an electronic data processor designed for analyzing the signals and for out-putting an alarm signal.
