RDS
Le système RDS (Railway Deformation System) est un système de surveillance non conventionnel conçu par Sisgeo pour la surveillance automatique de la déformation longitudinale des voies ferrées et du dévers (ou torsion) de la voie.
FLX-Rail
FLX-Rail® est un appareil de mesure de jeu de haute précision conçu pour mesurer automatiquement et en continu la déformation verticale maximale des rails à chaque passage de train.
Rome Underground – Line C – Italy
Rome metro Line C runs through the city from North-West (Della Vittoria district) to the eastern suburb and is extending beyond the Grande Raccordo Anulare.Line C has a full-run of 25,6 km and 30 stations, passing through the old town centre.The Route will be characterised by the green colour. The interchanges with the other metro […]
Milan Metro Line 4 – Lorenteggio–Linate – Monitoring of the underpass of railway trails RFI between stations “Forlanini Q.RE” and “Forlanini FS” – Italy
The main aims of the M4 realization are: to realize a new diametrical line from East to West, in order to connect through the historical center some highly populated urban areas that are not well served by the network of public transport; to interconnect with the whole railway system, urban and regional; to realize a […]
Milan arret Forlanini surveillance des passages souterrains nord et sud
The realization of the railway station Forlanini FS is connected to the realization of the M4 Metro of Milan (line 4). Forlanini FS station, which has been opened in May 2015, allows to connect the system of the suburban railway lines (S5, S6 and S9) to Linate airport, thanks to line M4.During the rails translation […]
FAQ#110 – What’s the purpose of the linear and polynomial factors written in the Calibration Reports?
Utilize the Linear Sensitivity Factors (A, B) and Ploynomial Sensitivity Factors (A, B, C, D) of the Calibration Reports permit to obtain readings in engineerig units with a maximum error as for the Calibration Report. In the case of analogue gauges, the factors shall be applied on the electrical readings (i.e. mA, mV, digit, etc…) […]
FAQ#095 – How long does a chain of digital sensors take to be read?
It mainly depends from the powering mode of the gauges (refer to FAQ#094 for the description of the powering modes). AN EXAMPLE WILL BETTER CLARIFY THE ANSWER. In a batch of 240 gauges, unless otherwise requested by the Customer, the addresses are settled from #001 up to #240. In a borehole is installed a chain of 30 […]
FAQ#094 – Which are the available powering modes for SISGEO digital sensors?
All SISGEO digital gauges can be settled in two different powering mode: The STANDARD powering mode is ALWAYS ON, so unless otherwise requested by the Customer, the sensors are settled as default in ALWAYS ON.
FAQ#077 – Quelles sont les longueurs maximales de câble depuis l’instrument jusqu’à l’enregistreur de données?
Les longueurs de câble maximales dépendent de plusieurs facteurs, et en premier lieu le mode d’installation et les protections de câble (blindage, terre, etc…). En supposant que les instruments sont installés selon les règles de l’art, les suggestions suivantes devraient être prises en compte pour la longueur maximale de câble: INSTRUMENTS NUMERIQUES: voir FAQ#073 INSTRUMENTS […]
FAQ#076 – Pourquoi est-il nécessaire d’ajouter une résistance de terminaison au dernier capteur numérique de chaque chaîne RS-485?
Tous les instruments numériques SISGEO (IPI, clinomètres, H-Level…) utilisent le protocole de communication série RS-485. Le protocole RS485 requiert l’ajout d’une résistance de terminaison. La connexion recommandée pour une chaîne utilise des nœuds « point à point » (multidropped) en mode bus (line). Les connexions réseau en étoile, circulaires ou ramifiées ne sont pas recommandées. […]
FAQ#075 – What parameters are saved in SISGEO digital sensors? What information must the Customer provide when ordering?
All SISGEO digital sensors (e.g. IPI, BH Profile, MD Profile, LT Inclibus, Tilt-meter, RDS, H-Level, etc.) use the Modbus communication protocol over RS-485 serial. SISGEO digital sensors are connected to each other with a single signal cable. The parameters that are configured at the factory for each digital sensor are as follows: Upon confirmation of […]
FAQ#073 – Quel est le nombre maximal de capteurs numériques (RS-485, Modbus), le nombre maximal de chaînes et la longueur maximale du câble dans un réseau RS-485?
Last update: October 2021 All the SISGEO digitized sensors utilize a RS485 interface with Modbus protocol. 1.The maximum number of digitized sensors in a RS-485 network are 247 (theoretical) 2.The maximum number of digitized sensors chains that is possible to connect to Modbus master unit (as OMNIAlog or miniOMNIAlog) are 4. 3. About the maximum […]
