Stations made to work in unmanned severe weather conditions, with low power consumption characterized by: • modular and high performing data acquisition system• able to connect distributed Wireless Sensor Network (WSN)• equipment and data transmission reliability • quality and accuracy of geotechnical and weather sensors Also available with dual data transmission system GPRS, Ethernet and/or UHF to ensure the highest system reliability.HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEO HMS-GEOHMS-GEO seriesTypical geotechnical unmanned HMS-GEO system• Stainless steel IP66 enclosure, with welded stainless steel brackets for mounting to pole• Data acquisition system based on Campbell Scientific CR1000 with enhanced software programming and automatic GPRS transfer of data• SIERRA Wireless Xtend modem GSM/EDGE with GSM antenna• 60W photovoltaic power supply kit with stainless steel brackets for mounting to pole and 40Ah GEL battery• Multiplexer + 24Vdc voltage regulator + CV120 relay module, to manage sensor supply geotechnical and metereological sensors• WSN system (spatially distributed autonomous sensors)+A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor environmental parameters, and to cooperatively pass their data through the network to a gateway node. The WSN is built of nodes, and each node is connected to one (or sometimes several) sensors. Each sensor network node has typically several parts: a radio transceiver with an internal antenna or connection to an external antenna, a microcontroller, an electronic circuit for interfacing with the sensors and an energy source, usually a battery or an embedded form of energy harvesting. WirelessSensorNetworkTo monitor the evolution of landslides, or instability of a slope, it’s possible to use different types of automatic sensors, depending on the nature of the phenomenon, and environmental conditions. The geotechnical instrumentation integrated into HMS-GEO series allow to acquire data about the main factors that determine the conditions of instability of the slope on the surface and in depth: inspection of the fracture surface, inspection of the sliding surfaces and deep of groundwater.The geotechnical sensors proposed below have all the features we consider essential:• solidity• reliability• integrationSome sensors supported by HMS-GEO can be managed in a WSN system. Geotechnical sensorsSeveral types of geotechnical and meteorological sensors are compatible with HMS-GEO system.A lot of accessories are available to customize your HMS-GEO system.• Enclosure: a large selection for all installation requirements.• Supply: to ensure correct “energy charge” to the system.• Stainless steel supports: reliability and durability guaranteed for all types of installation.• Electrical components: to drive better all the sensors and optimize energy consumption.• Installation and maintenance: specialized assistance from Assembly to Z.Accessories for HMS-GEO series Stainless steel supportsA wide variety of stainless steel supports is available, designed and engineered for each type of installation, also in harsh environment.The topology of the WSNs can vary from a simple star network to an advanced multi-hop wireless mesh network. In HMS-GEO series it’s possible to configure 3 types of WSN system, made by different producers; each has its specific potentials, to be considered on an individual basis.WSN CAMPBELL WSN XBOW WSN E-SENZADatalogger compatibilityCampbell ScientificCampbell Scientific / DataTakerCampbell Scientific / DataTakerPower supply internal internal / external internal / externalAnalogic outputs ? ? -Radio frequency 868 MHz (Europe) 868 MHz / 2.4 GHz 2.4 GHzGateway proprietary on SDI-12TinyOS (open source) ASCII on RS-232ASCII on RS-232/EthernetModBus on EthernetDatalogger CR1000Datalogger DT-80Multiplexer AM 16/32 BMultiplexer CEM20(*) using different reset and clock signal to realize parallel acquisition sessionsCR1000 CR800 CR200X DT-8xSE / DIFF inputs 16/8 (±5V) 6/3 (±5V) 5/- (0-2.5V) 15/5 (±30V)Digital I/O ports 8 4 2 8Digital pulse counters2 2 1 4Analogic outputs3 2 2 yesRS-232 ports 6 4 1 2Multiplexers 4* (AM 16/32 B) 2* (AM 16/32 B) - 5 (CEM20)WSN supported -GEOTECHNICAL • Piezometer• Extensometer – cable-extension transducers• Extensometer – borehole multiple point rod• Tiltmeter• InclinometerMETEOROLOGICAL• Temperature and humidity probe• Rain gauge• Snow depth and SWE system• TDR and water content probeHMS-GEO data acquisition system based on different data-logger:• Campbell Scientific CR-series• DataTaker DT-8x seriesIs convenient to use multiplexer to increase the number of sensors connected to a data-logger by signal cables, and there are several possible configurations to maximize the type and the number of sensors connected to a single data-logger. Each type of data-logger can support different multiplexer (see table below).Thanks to its experience in monitoring networks integration, since 2003 Hortus srl has designed, implemented, installed and maintained its own automatic environmental data acquisition systems (HMS-Series), based on Campbell Scientific data-logger, building the best technical solution for the customer’s needs.Being aware of the importance of having available data in real time, particularly during environmental crisis, like floods or landslides reactivation, our systems are equipped with redundant transmission system (standard IP using GPRS,WI-FI and Ethernet network, radio UHF, satellite connection).For data management, Hortus has designed a web platform that allows access, display and analysis of data from active monitoring systems. Hortus srl has more than twenty-year experience in the production of customized software for data acquisition and management collected by monitoring networks. The project of the first multi-protocol data acquisition installed in 1987 following landslide event of Val Pola, Valtellina, Italy. Since 1999 Hortus has dealt with the design, implementation and management of the web platform www.laghi.net, which is a recognized reference for the hydrological monitoring of the Italy’s northern region lakes.Environmental monitoring systemHortus srlvia Caboto 8/b 20025 Legnano (MI) - ItalyTel +39 0331 93.60.00 - Fax +39 0331 93.60.80e-Mail sales@hortus.it - www.hortus.it
