MHASTER DATALOGGER Over 40 years of experience in the specific field of environmental monitoring led CAE to develop the most advanced and reliable mul -risk monitoring system dedicated to man-made and natural phenomena currently available on the market: the Mul HAzard System (MHAS). The MHAS responds perfectly to the need for integra on into a single monitoring network of all elements related to several risk factors in large areas. The core of this system is the new Mhaster datalogger, capable of monitoring mul ple environmental risk scenarios such as landslides, fires, storm surges, floods, avalanches, severe weather condi ons... The Mhaster is the unit of acquisi on to which they referred all the management tasks of the equipment in the field. A powerful hardware has been built based on embedded Linux opera ng system to best achieve all these ac vi es, while ensuring high flexibility. Mhaster sta ons, implemented as the remote unit within automa c monitoring networks, can be configured in different ways and include different modules: - Open acquisi on unit, to perform controls, elabora ons and data logging; - Smart for input/output expansion, to collect data from a virtually unlimited number of sensors; - NRG module for advanced consump on control and management of different power systems; - Date Touch Screen user interface (DTS) 7 ” LCD, for the local management of the sta on. The strong modularity allows the tailoring of the remote sta on architecture on the Client's needs, high degree of flexibility, easiness to customize and respond more promptly to future developments. The high compu ng capacity made available by Mhaster allows a complete mul tasking, i.e. opera on allows users to perform mul ple tasks simultaneously. Communica on ac vi es and the elabora on by the datalogger happen, in normal condi ons, few seconds. This allows the op miza on of the opera on, with a consequent limita on

The high compu ng capacity of the data logger also allows the user to choose different ways of communica on, due to the full implementa on of the TCP/IP stack and advanced Web-based services, to offer compression and encryp on of data by means of standard procedures, as well as allowing development of applica ons by the Client or third par es. The standard protocols implemented in the Mhaster datalogger are varied: in addi on to the most common ones such as p, h p, ntp, ddns (and more), CAE also a empted to develop protocols that are specifically op mised for the monitoring field, which are becoming...

THE NRG POWER MANAGEMENT MODULE Mhaster data logger can be powered both by means of mains power supply and solar panels; in both cases an electronic device manages the automa c recharging of the buffer ba ery. This specific Mhaster power supply module, called NRG, has been developed by CAE with algorithms that op mise the ba ery life and recharging (based on MPPT technology ("Maximum Power Point Tracking")). This provides con nuous monitoring of the ba ery voltage, performs self-diagnosis func ons and issues alarms under cri cal charging condi ons. The module is also already suitable to manage...

"basic Measures" to each and every second and use “crude Measures and "atomic Measures” related to a millisecond scale. Even though all measurements can be used for further processing, only basic measures are stored in the memory of the data logger for further processing in compliance with WMO provisions. Data are saved without encryp on and without having to purchase special so ware, are easily accessed through standard formats both for physical users and machines. The machine to machine (M2M) interac on is provided by a WebService on board the Mhaster, allowing the clients to use data as they...
