ESTABLISHED SOLUTIONS
Graphic operator panel
A graphic operator panel provides only basic information about the
current state of the system via web interface or simple visualization
(touchscreen). It does not facilitate efficient processing of historical data
and complex evaluation of functioning of the whole building.

Online viewing of technological data
integral part of measuring and control
Alarms - only to a limited extent
minor extensibility of the system
Historical data - very limited
harder to ensure security
Evaluation of energy consumption - very limited
unsuitable for greater installations
User reports - none
Local control center
A local control center is a traditional way of visualizing technical systems
of a building. It requires that the operating company continuously
maintains HW, upgrades SW instruments, and regularly backs the whole
system up. This stands for considerable costs. The online availability
of data including historical data is usually restricted only to a certain
computer and chosen technical employees.

Control center as a service
Mervis is a service for complex supervision of all operated technologies.
This cloud service provides unified centralized data processing and their
easy availability for local operating personnel, central supervision, and,
if needed, management access.
It can totally replace local control center and, moreover, adds functions
for advanced data evaluation, reports, and effortless access from mobile
devices for variety of employees. Thanks to being entirely open, Mervis
can be freely connected to additional systems, which need to further
work with the operational data.
NET
Mervis responds to present-day requirements on functional and flexible
systems and comprises all important components of regular SCADA
systems. With the help of modern cloud technology, a constant updating
of the system with immediately available new functions is ensured.

Modern building control and active energy management
The share of energy and media costs will increase even
more in the future and their proper control is high
on agenda of all well-managed companies.
To react to this trend, our company created the unique
Mervis system for its customers.
The system is designed particularly for:
• control of technical equipment in buildings
• monitoring, evaluation, and management of energy
and media consumption
• monitoring and evaluation of failure states and emergencies
The system facilitates energy
and media savings of up to
30%
TECHNICAL SOLUTIONS OF Mervis SYSTEM
Mervis SCADA
The essential part of the whole system is SCADA
(Supervisory Control And Data Acquisition). SCADA
ensures basic functions of the system needed by technicians-controllers in their work to monitor and to manage the controlled technology. For every connected building or area, a data
file is defined which specifies the means for data display and
communication with terminal equipment. The display has three
basic modes:
• as a list of data points
• as graphic technological diagrams
• as historical charts and overviews
Mervis DB
Values from the single data points are periodically stored in the database of historical data. In this database,
the data are saved in a special form which enables storing and
managing great amount of data (in the order of billions and
more records) and fast search and display of the required data
at the same time.
Mervis NOTIFICATOR
Mervis NOTIFICATOR is a special module which serves to control the processing of information about
nonstandard situations, failures, and emergencies. The system
is able to communicate via:
• sending SMS
• sending informative e-mails
• sending messages to user‘s help desk (e.g. Alstanet AFM
system)
Within the system, the workflow can be set, i.e. when, to whom,
and how messages will be sent. The system stores all alarms
in a historical overview and allows their further evaluation and
processing.
Mervis ENERGY DASHBOARD
Energy Dashboard (ED) is a specialized module designed for monitoring and evaluation of energy and
media consumption. ED compares the remotely-read real
energy consumption with a mathematical model used both as
a comparison base and consumption forecast for several next
days. It can be utilized for all applications with online collection of data on consumption of heat or similar energies depending on climatic conditions or other influences (e.g. production
in manufacturing companies).
Mervis WEATHER
To optimize the control in specific buildings, online
data from the weather forecast can be used. The data
from this module are utilized directly by the regulating system.
The achieved savings account for as much as 7 %.
Mervis REPORT
It enables the Mervis system to generate special user
reports as combinations of predefined xls files created by the client and historical database data automatically
added to the xls files.
Mervis PLUGINS
Thanks to an open interface, the SCADA system facilitates the integration of additional plugins (supplementary modules) delivered both by our company and third parties.
One of the plugins is a predictive regulation for control of heating and cooling in buildings (MPC - Model Predictive Control). The predictive regulation uses a thermodynamic model
of a building to optimize the control and thereby to achieve
energy saving of more than 10 %.
