Supervisory Control and Data Acquisition (SCADA) systems automate and optimize day-to-day remote control and monitoring for varied applications including factory automation, environmental control, transportation and Building Energy Management Systems (BEMS). For the oil and gas industry, SCADA systems play a vital role in hierarchical oilfield management. Of course these systems must employ a high-performance and reliable operating platform that can process large amounts of data and precisely transmit that data from remote fields to the control center in real time. Advantech offers a pair of SCADA servers featuring new industrial designs with high computing power and storage capacity that provide the best reliability to meet the demanding requirements for oil and gas applications.

Advantech proposed two kinds of SCADA servers: a 4U model with HPC-7442 and ASMB-782, and a 2U model with HPC-7242 and AIMB-782, both with industrial motherboards and redundant designs that met the requirements of the different management layers. Apart from CPUs and HDD trays, there is no difference between these products, and both are qualified for use as SCADA servers. The 2U model, equipped with HPC-7242 and AIMB-782, is suitable for oil regions or oil stations in unattended areas and can endure high temperatures, as well as dusty and unstable power supply conditions. HPC-7442 plus ASMB-782 together provide faster quad-core processors and greater hard-disk capacity, and were installed in the control center to deal with the huge data streams incoming from the fields.

Both the 2U and 4U models offer many advantages that ensure SCADA systems’ stability and security. With regard to stability, Advantech chooses the best materials and parts to avoid damage from high temperatures, such as high quality solid capacitors and robust CPU cooler mechanisms. The special circuit discharge design eliminates abnormal power sequence issues and allows the system to reboot normally if voltage instability occurs. To maintain high quality network transmissions and prevent data loss, both SCADA servers support Dual LAN ports with Intel® teaming functions to maximize throughput for network transmission during normal operation, and each port can serve as a backup link if the other is disconnected.

As for security, Advantech designs in chassis intrusion detection to notify the system administrator; if someone opens the external case without permission, the system generates an alert message that informs the control room. These SCADA servers also offer lockable front metal faceplates that secure thehot-swappable hard drives; they also secure the internal USB connectors where customers can connect USB thumbdrives inside the chassis. Trusted Platform Module (TPM) is another optional feature that safeguards the client’s confidential data. Motherboards with TPM provide hardware-based protection for encrypted data; the data remainswell protected even if the hard drives are stolen.

In response to this unmanned application with multi-level architecture, Advantech’s remote device monitoring software – SUSIAccess – helps the customer to inspect the condition of hardware devices, reporting system temperature, fan speed, voltage, etc. If there is any abnormality, an automatic alarm alerts the administrator. In addition, a system with smart fan control dynamically adjusts fan speed according to the temperature level to optimize heat dissipation and acoustic balance. This complete monitoring approach upgrades remote management to intelligent management.
