CEMView DB-PAC

The CEMView DB-PAC is a series of PC-based data acquisition and control (DA&C) Programmable Automation Controllers (PAC).

The CEMView DB-PAC is a Windows Embedded industrial single board PC designed to provide local data acquisition, storage and control for the CEMView Continuous Emissions Monitoring (CEM) Data Acquisition System (DAS). The DB-PAC can communicate directly to gas analysis instruments using on-board RS-232/422/485 serial ports or Ethernet ports. Additional serial RS-422/485 ports can be added with Ethernet Serial device servers. The DB-PAC is designed for typical deployment in a CEM shelter.

The CEMView DB-PAC application software supports OPC Data Access and OPC Alarms & Events specification interfaces. The CEMView DB-PAC is responsible for real-time control and sequencing activities such as probe blowback and calibration valve control sequencing. It can acquire measured data from the gas analysis instrumentation using an instrument specific OPC Server. Automatic data reduction capabilities are built into the system’s CEMView DB application software. The data reduction algorithms can be customized to meet the automatic data reduction requirement of regulatory compliance authorities and jurisdictions. Microsoft SQL Server  is used for historical data storage.

The CEMView Client application component of the CEMView system connects to the CEMView DB OPC Server to acquire the real-time data. An OLE-DB provider connection to the Microsoft SQL Server 2005 Express Edition database is used to acquire the historical data.

CEMView DB-PPC

The CEMView DB-PPC is a Panel PC based Programmable Automation Controllers (PAC) with 15″ or 17″ TFT LCD and Touchscreen designed to provide local data acquisition, storage and control for the CEMView Continuous Emissions Monitoring (CEM) Data Acquisition System (DAS).

The Windows Embedded operating system is optimized for the hardware and installed on industrial solid state drive.

The DB-PPC can communicate directly to gas analysis instruments using onboard RS-232/422/485 serial ports or Ethernet ports. Additional serial RS-422/485 ports can be added with Ethernet Serial device servers.  The DB-PAC is designed for typical deployment in a CEM shelter.

For CEMView CEM DAS applications, the CEMView Data Buffer application software is typically installed on the DB-PPC.  It supports the OPC Data Access and OPC Alarms & Events specification interfaces.  The CEMView DB-PPC is responsible for real-time control and sequencing activities such as probe blowback and calibration valve control sequencing.  It can acquire measurand data from the gas analysis instrumentation using an instrument specific OPC Server.  Automatic data reduction capabilities are built into the system’s CEMView DB application software. The data reduction algorithms can be customized to meet the automatic data reduction requirement of regulatory compliance authorities and jurisdictions.  Microsoft SQL Server is used for historical data storage.

The CEMView Client application component of the CEMView system connects to the CEMView DB OPC Server to acquire the real-time data.  An OLE-DB provider connection to the Microsoft SQL Server database is used to acquire the historical data.

CEMView IRPC

The CEMView-IRPC is an industrially hardened computer for Continuous Emission Monitoring (CEM) applications that strikes a balance between economy and reliability.  The CEMView-IRPC Rackmount steel chassis provides a rugged, dust-free enclosure while allowing superior airflow for reliable, stable operation in harsh environments.

Intel Core and Intel Xeon server class dual core and quad core processors are also optionally available.  The extremely powerful graphics engine video controller, LAN controller and RAID controllers are all integrated onto the motherboard, effectively reducing or eliminating the number of add-on boards and components.  CEMView-IRPC embraces the latest Intel CPU and PCI Express technology.

Using two RAID Edition Serial ATA drives, the RAID 1 data storage array delivers superior reliability, high fault tolerance and excellent performance. Designed and manufactured to enterprise-class standards, these RAID Edition drives provide enhanced reliability in a 24×7, high duty cycle environment and they offer a RAID-specific time-limited error recovery feature that improves compatibility with RAID adapters.  The RAID Edition Serial ATA drives are mounted in anti-vibration disk drive bays with hard drive coolers.  A vibration isolated cooler hard drive will be more stable and less likely to suffer a mechanical failure.  Keeping the drives well below its specified temperature range is the easiest way of ensuring that the drives will perform optimally.  For harsh or high vibration environments, extended duty 2 ½” notebook hard drives or SSDs featuring 24/7 operation, high shock tolerance and mean-time-between-failure of 500,000 power on hours are also optionally available.

Memory heat-spreaders are used to dissipate heat, improving its performance and avoiding system crashes caused by overheated RAM. Data archiving to CD-R/RW or DVD-R/RW optical media is secure and easy. The high speed USB 3.0 interface ensures that alternative back-up peripheral or add-on hardware such as tape drives are easily connected to the system.
