| 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 (30a) 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). |

1. System for monitoring the physical and/or analog parameters concerning parts of an engine, said system comprising at least one electronic control unit configured to call up, by the intermediary of at least one antenna, a surface acoustic wave sensor located on one of said parts, wherein:
the engine is compartmentalized, each compartment comprising a plurality of mobile or fixed parts of which the physical and/or analog parameters need to be monitored, each of these parts to be monitored is provided with a surface acoustic wave sensor, with these sensors each having a distinct resonance frequency specific to them, an antenna is installed inside each of the compartments, with each of these antennas being connected, alone or in pairs, to an 20 electronic control unit, each antenna is controlled by the electronic control unit to which it is connected, to simultaneously emit a plurality of distinct frequencies close to the resonance 25 frequencies of the sensors which are located in the engine compartment of said antenna, so as to simultaneously communicate with all of these sensors. |
