Provide remote monitoring to the installed gas leakage/theft detection system. This system was installed on seven different remote locations on a pipeline and it required a highly secure and reliable method of communication.
Solution requirements:
• Industrial grade devices providing reliable operation under extreme industrial environments.
• High data rate network.
• Secure accesses.
• Network redundancy to prevent data loss in case network goes down.
After a number of site visits, Xceltra provided Sumed with the M2M remote connectivity solution. This decision was made based on the following factors:
• The sites were scattered and had good mobile network coverage.
• The path study carried showed that using wireless solutions will require huge investment in the hardware.
• Using the wired solutions wasn’t an option.
• Not preinstalled in the infrastructure which will require a huge installation cost.
The designed M2M remote connectivity consisted of an openvpn set up using 3G Gateways for the following reason.
• Achieves the desired speed through a stable 3G connection.
• Mobile operator independent static IP addressing with M2M Gateway.
• Temperature ranges: –40 to +75 °C.
• Hazardous location certification: Class 1 Division 2 to prevent explosion initiation.
• Support for several encryption protocols for secure communication.
