| Data Acquisition and Control Systems |
LOGIS-TECH's (LTi) Environmental Data Acquisition, Monitoring and Controls Systems
are comprised of a suite of sensors, process controllers, network access interfaces,
Human Machine Interfaces (HMI) and software packages. Our systems provide flexibility
and customization to meet the customer’s requirement for full-time unattended automated
safe control of their ADU/HVAC system(s). The typical package provides real-time automatic
control and condition monitoring, automated data collection and processing.
The LTi control paradigm includes the requirements to support Unattended Automated
Control, Operations Verification, HMI, and Automated Reporting Services.
Unattended Automated Control
Components are selected and integrated to provide for fully automated, unattended
control of the Environmental Processing Equipment. Available options allow for safe
and efficient operation using remote sensing devices to detect not only temperature
and relative humidity conditions but other potentially critical data inputs such as
door position and the presence of any carbon based combustible atmospheric gases.
At the heart of LTi's control system lies the Simplified Control System (SCS™). Individual
components may be added or subtracted to the SCS™ to create and support the proper
system functions required to accommodate various operational requirements, including
environment stabilization of temperature and humidity, toxic/combustible fume
regulation, security monitoring, fire protection and light level conditions.
Components are selected, tested and integrated into the system to stress reliability
and ease of operation and maintenance.
Individual Components of an SCS will vary, but will include some if not all of the
following:
Sensor Networks:
Environmental Monitoring
• Ambient Relative Humidity and Temperature (Dew Point Available)
• Space or Process Control (RH-T)
• Combustible Fumes
• Light Levels (LUX)
• Door Interlock Sensors
Machine Performance and Condition Monitoring
• Machine Performance Monitoring
• Runtime and Meter Monitoring
• Monitoring of Equipment Fault Conditions
SCS Unit Controllers:
• High Speed Controllers
• Modular Design allows addition of functions and advanced capabilities
• Programmable to specific requirements
Communications:
LTi has a number of Communications options that allow for remote access into
the system(s) for data review and system configuration. Options exist for:
• Standard Modem via Standard Telephone connections
• Wireless Cellular (analog and digital)
• Wired and Wireless Internet
Remote communications coupled with one of our service contracts provides
a powerful package to assure continued operation at the ESS'®' system or your operational equipment.
Operations Verification
The collection of the data points used in the calculation for control and operation
of the system are logged to provide verification of system operation and compliance.
Data points are stored in non-volatile memory for future offloading and evaluation.
Log functions can be tailored to provide highly detailed views of operation or show
long-term operation conditions of the system or equipment.
HMI
All SCS deployments can be monitored locally with network interfaces and properly
outfitted computers. Most SCS systems are also built to leverage available communications
assets for remote monitoring. Options are available for Wire-line Telephone or POTS
(Plain Old Telephone Service), Wireless Cellular (Analog and Digital). Fixed and Wireless
Internet connections are available depending on the customer need and the availability
and access to these technologies.
HMI interfaces allow the interaction with and configuration of the SCS.
Historical data records may be reviewed, controller operation set points may be
modified, real-time sensor conditions may be displayed. HMI’s may be simple equipment
mounted digital displays or alarm enunciators, locally running laptops with our
proprietary Guardian™ software, other LTi utilities or full featured remote internet
and World Wide Web Based tools.
Automated Reporting Services
LTi’s commitment to increase efficiencies, reduce costs, provide quality products and
services, has led to the development of the Management Automated Reporting and Storage
System (MARS™). MARS™ is the primary tool used in the data collection and reporting of
SCS™ and other control networks deployed world-wide. The technology is used to warehouse
data, automate and manage system performance evaluation and reporting. The system performs
automated scheduled daily checks of every active site by retrieving operational data files
that have been stored since the last contact. These data sets are evaluated to ensure that
the system is within proper operational parameters. If parameters are not within acceptable
range or certain other error conditions exist, such as if no communication is possible,
alerts are raised and forwarded to LTi’s Service Network. All data points and alerts are
then stored in a massive database for later use and more in-depth review. The stored data points
are also used for the automated preparation of all required weekly, monthly or quarterly
performance reports.
MARS is fully web-enabled allowing LTi employees and its customer’s on-line access to their
site(s) performance data from any public internet connection. These information points and
more are available on demand at
logis-tech.net via secure customer specific login.
