摘要:
The invention concerns a system for monitoring physical and/or analogue parameters relative to the parts of an engine, said system comprising at least one electronic control unit (30 a ) configured to call up data, via at least one antenna (20a), from a surface acoustic wave sensor located on one of said parts, characterised by the fact that: - the engine (M) is compartmentalized, each compartment (Ma,..., Mf) comprising a plurality of mobile or fixed parts of which the physical and/or analogue parameters need to be monitored, - each of these parts to be monitored is provided with a surface acoustic wave sensor (101a, 102a, 103a,..., 101f, 102f, 103f), each of said sensors having a distinct resonance frequency specific to it, - an antenna (20a,..., 20f) is installed inside each of the compartments (Ma,..., Mf), each of said antenna being connected, alone or in pairs, to an electronic control unit (30a,..., 30f, 30ab,..., 30ef), - each antenna (20a,..., 20f) is controlled by the electronic control unit (30a,..., 30f, 30ab,..., 30ef) to which it is connected, to simultaneously emit a plurality of distinct frequencies close to the resonance frequencies of the sensors (101a, 102a, 103a,..., 101f, 102f, 103f) which are located in the engine compartment (Ma,..., Mf) of said antenna, so as to simultaneously communicate with all of these sensors (101a, 102a, 103a,..., 101f, 102f, 103f).
摘要:
The invention relates to a mooring chain stopping device, comprising: a locking housing (50) provided with a channel (53) inside which a mooring chain (2) is capable of sliding, said housing including a means for connecting to a buoyant structure (1), which is configured to direct the axis of said channel to the pulling axis (A) of said chain, said housing further having built-in bolts (2) that are configured to inhibit the sliding of said chain in said channel; and a means for measuring the tension in said mooring chain, said measuring means being built into said locking housing, characterized in that said measuring means includes: at least one chamber (6) consisting of a deformable, closed shell, said chamber being filled with a liquid; at least one bearing part (7) movably mounted in the locking housing (50), said bearing part being placed between the bolts (52) and the chamber (6), said bearing part engaging with the wall of the shell of said chamber so as to pressurize the liquid contained therein, said bearing part being arranged such that the forces exerted by said mooring chain (2) on said bolts (52) causes the movement of said bearing part and the pressurization of said chamber; and at least one pressure sensor (8) configured to measure the pressure of the liquid in said closed chamber (6).
