Cloud based energy monitoring from Carlo Gavazzi
06 October 2013
The VMUC-EM is the latest energy platform from Carlo Gavazzi which has moved energy monitoring to the cloud.
The VMUC-EM collects data from the energy meters as well as temperature inputs and it can switch outputs. It then exposes the data to local networks and the internet by providing three Web services.
These include a file transfer protocol (FTP) server, which enables data to be pushed to a capable BMS, server or cloud-based service provider on a scheduled basis; an HTTP client that allows data to be pulled on demand; and a Web server providing always-on access to real-time data, trending and alarms.
Logged instantaneous variables of each meter can be displayed on daily, monthly or annual basis. The easy to read GUI displays the entire installations energy consumption. This data can be acquired from either the main meter or a virtual meter, which is the sum of any pre-defined sub-meters.
Trends such as, day/week/month compared with the previous (working or non-working) day/week/month. Any alarms that may have occurred in the plant can easily be displayed or sent via email or SMS. There are 3 different categories: events (any changes occurred to the system configuration), anomalies (abnormal conditions of the monitoring system), alarms (set-point alarms or communication errors).
To help drive down costs, estimations can be made based on a dual tariff system which includes active and reactive energy costs, and any monthly penalties that may occur due to exceeding the contractual power allowance. All data is easily exported in a csv format.
