DSM Panel PC controls and monitors solar park system

To use the power of the sun as energy source, the manufacturers of large solar park systems are going into the desert. Because the large surface area systems near towns would be an eyesore for the inhabitants, the decision was soon made to use the desert areas absent of humans for electricity generation. Its extreme robustness (IP65), allows the Infinity® Panel System "P5" (96M9335) to be used without problem for the control and monitoring of the solar park system.

The fan-free industrial PC is equipped with an integrated keyboard and a 15" TFT color screen. This screen has a maximum resolution of 1024 x 768 pixels with a luminance density of 250 cd/m². The industrial system is equipped with an Intel® Celeron® M (ULV) processor with 1.0 GHz clock rate. The use of the power-saving CPU means the Panel PC system does not require a fan. The main memory can be expanded to maximum 1 GB RAM. The integrated Intel® 82855 GME graphic controller chipset guarantees excellent picture quality.

To save the large data volumes supplied for monitoring, the Infinity® Panel PC provides not only a 3.5" and 5.25" slim-line drive slot, but also a 2.5" EIDE "rugged" hard disk with 80 GB capacity. This hard disk is designed for continuous operation under harsh conditions. As an option, a CD/DVD ROM can also be integrated in the computer. The optional Compact Flash type II socket allows the system also to run without requiring any rotating mass storage.

The on-board Intel® GigaBit 82540 EM Ethernet controller provides a 10/100/1000 Base T/TX connection for a fast network connection of the Panel PC. It is also possible to implement a dual-LAN network, and, when used in the solar park system, a wireless connection that conforms to the IEEE 802.11 b/g standard. To ensure the required computer flexibility, serial interfaces, two PS/2 and two USB connections are provided.

The Panel PC electronically controls the sun collectors of the solar park system so they face the sun. This makes effective use of the sun hours and the generated solar electricity either flows directly into the power supply system or is stored. The WLAN connection allows the complete solar system to be monitored and controlled remotely. The individual computer units are connected with the main system, the Infinity® Panel PC. This allows specific system parameters to be queried or new values entered. The orientation of the solar collectors can also be controlled by the Panel PC. The DSMP® Condition Monitoring Program provides support for the complete system by continually monitoring fixed and variable parameters, such as operating temperature, processor temperature and hard disk status. The software transfers the data by WLAN to the main computer. This allows the technician, without being present on-site, to query or change specific values or, if necessary, deactivate individual collectors.
