embedUR team has architected applications for the burner, hydro-electric, automated material movement systems for various clients in India, Europe and USA. The team has been involved in defining requirements to on-site integration and installation for these very large and complex systems.
Hydro-electric systems
The hydro-electric system installed in France was out-sourced to India by the
French client. The entire software development effort from requirement
analysis, designing, developing and verification of the software was done in
India, with the integration and installation being performed on the customer
premises. The client was periodically updated with the status of the project
and had complete visibility into the various stages of the development cycle.
The software included developing a configuration database to define all the
control and monitoring elements of the system. This was the input to the
run-time software which would monitor these elements by periodic updates
from the PLCs through the MODBUS protocol. The PC based software
controlled and monitored over 2000 digital I/Os and over 500 analog inputs
and outputs. The Supervisory and Control Data Acquisition system provided for
fault detection and alarm suppression based on a user defined hierarchy of
alarms.
Burner Management Systems
For the burner management system, the PC based software provided for
monitoring of the temperature of the furnaces relayed by the Allen Bradley
PLC over the MODBUS protocol. The software provided the user with the
ability to program up to 15 temperature curves. On selection of one of these
curves, the software would communicate with the PLC to turn on the furnace
and control the temperature of the furnace through monitoring and control of
the various valves to maintain the temperature curve.
Automated Material Handling Systems
The automated material movement software was customized for some major airports, warehouses and mail handling systems. It involved tracking of the
packages based on various bar code sensors along the path of the package
and storing them in appropriate bins prior to retrieval and dispatching them to
the correct destinations. The software was responsible for managing the
storage areas and defining the path of the packages on entry to the system.
The system consisted of a UNIX based work station, Allen Bradley PLCs to
control the conveyors over TCP/IP sockets and socket based proprietary
protocol for controlling the cranes to store and retrieve packages from the
storage locations. |
