Abstract
An electrical data bus system comprises at least one monitoring device for detecting leakage of a flammable gas within a fuel zone. Pursuant to the method, upon a flammable gas leak within the fuel zone being detected, the flow of electrical current in the fuel zone, via the data bus system or any device connected to the data bus system, is prevented.
Claims23
Method of operating an electrical data bus system which controls at least one monitoring device for detecting a flammable gas leak within a fuel zone, wherein upon a flammable gas leak within the fuel zone being detected, the flow of electrical current in the fuel zone via the data bus system or any device connected to the data bus system is prevented.
An apparatus for detecting a flammable gas leak within a fuel zone, comprising:
- an electrical data bus system;
- and
- a monitoring device, delivering electrical signals to or receiving electrical signals from the data bus system, for detecting a flammable gas leak within the fuel zone,
- and configured so that upon a flammable gas leak within the fuel zone being detected, the flow of electrical current in the fuel zone is prevented.
