DSM embedded computers in operation for the alternative power generation

The increasing popularity of alternative power generation also increases the technical demands placed on the associated control and measurement data acquisition systems. Robust embedded computers developed for use in harsh environments, such as DSM Computer AG's E3-COM and E3-COM Intel® Atom™ NanoServers®, are particularly suitable for this purpose.

The embedded controller (96M1566L) operates in the extended operating temperature range from -10° C to +45° C and, thanks to its compact dimensions of only 220 x 220 x 110 mm and the supplied installation rails, can be installed in many applications. The E3-COM Intel® Atom™ (96M1565L) NanoServer® provides the user with another variant of the mobile and stationary embedded computers. The processor based on the Intel® Atom™ micro-architecture is envisaged for systems that have a particularly low power consumption. The Intel® Atom™ computer operates in the 0° C to +50° C temperature range and also has the same dimensions of 220 x 220 x 110 mm.

The two fanless E3-COM and E3-COM Intel® Atom™ NanoServers® contain a mini ITX baseboard with an appropriate computer-on-module for the COM Express™ standard. The module is also based on the Intel® Core™ 2 duo-processor L7400 and the Intel® 945GME chipset or the Intel® Atom™ N270 1.6 GHz processor. The on-board Intel® 950 graphic media accelerator ensures an excellent graphic processing power. The COM Express™ module also provides a security function that protects the application software on the computer system from unwanted external accesses.

The integrated 2.5-inch hard disk (Ultra DMA/33/66/100) with a capacity of 80 GB designed for harsh environments also allows operation in the extended temperature range. A maximum of two Compact Flash cards can also be used as mass storage for the "E3-COM" and "E3-COM Intel® Atom™" embedded computers. This allows the operating system and the application data to be separated physically, even for pure flash-based systems.

The embedded systems can be connected to the alternative energy plant using either Ethernet or optionally also WLAN. The NanoServer® restarts automatically after any interruptions to the power supply, such as power failure. The systems can also be started remotely from the WLAN.

The DSMP® system monitoring program installed for additional remote maintenance of the embedded computers provides software to continually monitor the most important operating parameters. DSMP® monitors the processor temperature, the supply voltage, the fan speed, the hard disk status, etc. The system monitoring software increases the operating reliability and the system availability of the NanoServers® and allows any hardware faults to be detected early, even before failure of important components.

Because all alternative power generating plants are designed to have a minimum service life of approximately 15 – 20 years, the long-term availability of the embedded computers is also important. DSM guarantees the system availability of the E3-COM Intel® Atom™ and E3-COM NanoServers® for at least five years. The quality of all installed individual components is guaranteed at the DSM factory by the established and tested quality management system in accordance with ISO 9001:2000.
