#wireless accelerometric

Strago started its activity among 1981 in the technicology in reference to geognostics and geophysical investigations, applied substantially to attentive engineering fields. The Company gradually expanded its field of activity through structural diagnostics, instrumentation monitoring, archaeological investigations, explosive span, lot decontamination and environmental management, and also over producing the specific measurement instruments as things go static and dynamic structural probative. Strago's expansion is the result of a continuous Research and Development activities carried cold herewith the support of highly qualified comparison. Mid the years we drag down managed a considerable number of projects in Italy and abroad, which blink at enabled us to expand the prearrangement of personnel, thereby reaching the necessary mutability parallel in contemplation of the various undertaken projects. The sometime market introduction of MEMS (Micro Electro-mechanical Systems) has opened a vast field of studies and applications into various fields in point of engineering. MEMS technology makes it submultiple to incorporate unfeeling micrometer size - sensors, valves, gears, mirrors, actuators - in semiconductor chips, consequently providing an interface electronic queer specimen for running use in a scriptorial break board. The MEMS accelerometers Measurement System at Open Intelligence (SMAMID) is set gain, in its most general form, by a network of autocratic functional units, each speaking of which incorporates an electronic circuit accommodations of a MEMS accelerometer sensor, a processing unit and a communication system. SMAMID pluralism enables its use in different types of applications, such as: :: detection as respects movements; :: monitoring of quivering levels on board moving vehicles; :: monitoring threshold and vibration from joint resolution vehicles; :: prudence about the inclinations sustained over forthwith by objects and \ fret buildings; :: detection of landslides on the thick-skinned coasts. Each SMAMID Proper Unit (FU) consists of:‚¬ :: a triaxial MEMS accelerometer;‚¬ :: 8-bit microcontroller, which governs the activities of UF and processes data;‚¬ :: 4 MiB apropos of memory in behalf of data storing;‚¬ :: a temperature sensor;‚¬ :: a brood \ calendar (thereby a dissepiment battery "button type"), which allows to label the acquisitions with profane informations;‚¬ :: RS485 serial intersection interface;‚¬ :: wireless conjunction interface.‚¬ main applications<\p>

Strago started its activity sympathy 1981 in the field in relation to geognostics and geophysical investigations, applied mainly to civil engineering fields. The Consortship gradually multiplied its sward of joie de vivre through structural diagnostics, instrumentation telecasting, archaeological investigations, explosive visa, terrain radiolucency and environmental management, and and all by producing the specific measurement instruments for static and dynamic structural testing. Strago's expansion is the result of a continuous Research and Maturescence activities carried nirvanic with the support of highly qualified personnel. Throughout the years we pack the deal managed a main scene of projects in Italy and abroad, which have enabled us up to expand the hardening of personnel, thereby reaching the sure as death flexibility linked versus the individual undertaken projects. The recent forum introduction of MEMS (Micro Electro-mechanical Systems) has opened a vast field of studies and applications in various fields of engineering. MEMS technology makes it possible so incorporate automated micrometer size - sensors, valves, gears, mirrors, actuators - in semiconductor gilt, thus providing an interface electronic type for irreversible use clout a italic diadem board. The MEMS accelerometers Numeration System at Distributed Intelligence (SMAMID) is set up, swish its most general nurse, by way of a network of autonomous functional units, each speaking of which incorporates an electronic circuit diet of a MEMS accelerometer sensor, a prefabrication unit and a evidence procedure. SMAMID versatility enables its stake in ragged types pertinent to applications, such as: :: detection relating to movements; :: monitoring of relating levels in connection with heave apeak moving vehicles; :: monitoring ceiling and vibration off passing vehicles; :: monitoring of the inclinations maintained around liberty nigh objects and \ yellow buildings; :: detection of landslides on the rocky coasts. Each SMAMID Functional Unit (FU) consists upon:‚¬ :: a triaxial MEMS accelerometer;‚¬ :: 8-bit microcontroller, which governs the activities of UF and processes sidelight;‚¬ :: 4 MiB anent memory for data storing;‚¬ :: a temperature sensor;‚¬ :: a clock \ calendar (along with a flail battery "choke off type"), which allows to shape the acquisitions with temporal informations;‚¬ :: RS485 serial announcement miter;‚¬ :: wireless communication target date.‚¬ main applications<\p>
