Automated ventilation control system (ASCS) is a technology for controlling ventilation systems of buildings and premises for various purposes.
On December 29, 2016, Krug announced the release of ACS by ventilation - ASUV.
The technology is developed to reduce the cost of energy consumption and operation of ventilation systems, improving the quality of air exchange process control.
System tasks
- Creation of a full-fledged automated ventilation control system
- Display graphical information about the state of ventilation systems
- Ensuring the possibility of phased implementation and expansion of the system to full-scale ACS with building life support systems.
Functionality
- Collection and processing of operational information from sensors and actuators on measured modes and parameters of engineering equipment operation
- Display of operational information in the form of mnemonic diagrams, trends on AWS monitors with delimitation of user access rights
- System Event Logging
- Notification of disturbances (process alarm)
- Control of ventilation units (automatic and manual remote)
- Maintaining the assigned air temperature through the channel sensor using the built-in PID regulator
- Room Temperature Sensor Cascade Control
- Preheating of Ventilation Water Heater
- Monitoring of ventilation units operation modes
- Air filter pollution control of ventilation unit
- Automatic Scheduled Operation
- Diagnostics of the validity of the received information
- Archiving parameter history.
Architecture
The automated ventilation control system (ASCS) is represented by three hierarchical levels:
- first (lower) level
- signal sensors and actuators. The S2000-T controller parameter list is applicable to each type of ventilation system.
- second (middle) level
- S2000-T controllers manufactured by BOLID. Controllers provide performance of functions of control, regulation and control of engineering equipment in the amount sufficient to maintain operation of all three types of ventilation systems (plenum, exhaust, plenum-exhaust) in the ratio "one system - one controller." For exhaust ventilation, two ventilation units are connected to the controller.
- third (upper) level
- automated workstation (AWS) of the operator based on SCADA KRUG-2000, combined by functions with the archive server.
Analog and discrete signals from sensors and actuators of the plenum, exhaust and plenum-exhaust ventilation are supplied to the controllers, undergo primary processing and then transmitted via the digital RS485 interface (Modbus protocol) to the operator's AWS for their further processing, display and storage. Remote control of actuators of ventilation systems is performed from the operator's AWS.
Features
S2000-T Controller (manufactured by BOLID):
- specializes in performing monitoring, regulation and control tasks, including as part of automation and dispatching systems for engineering equipment of buildings
- It has onboard inputs/outputs (6 discrete inputs, 6 discrete outputs, 6 analog inputs, 2 analog outputs) for connecting signal sensors and issuing control actions on actuators, which does not require the purchase of additional equipment, for example, physical signal input/output modules
- supports exchange via the standard Modbus software protocol
- provides easy and easy software configuration
- production in Russia.
Expected Implementation Results
- Creation of a full-fledged supervisory control and control system with the ability to continuously monitor the operation of the ventilation system
- Timely provision of high-quality information to operational personnel on process progress, state of engineering equipment and technical controls
- Reduction of probability of erroneous actions of the operator due to timely presentation of information in visual form
- Increase the operational life of ventilation equipment by immediately responding to system failures
- Reduction of energy resources consumption due to implementation of automatic control and control functions
- Possibility of scaling and expansion of the system functionality, including by the Customer
- Minimizing engineering costs by Owner, only project setup required
- Long-term data storage
