Abstract:
1. A method to capture and portray information respecting airborne noxious gases present in the atmosphere of or down-wind from a gas or oil production well-site not having access to the communications and power supply public infrastructure typically associated with populated areas, for the purpose of warning remote operators of said well-site of the presence of said gas, the method comprising: detect, and generate raw data respecting, each said gas present in said atmosphere; sense atmospheric conditions that cause anomalous readings respecting any said gas so detected; process said raw data to identify each said gas detected and the concentration thereof so as to generate processed data respecting each said gas present in said atmosphere; wirelessly communicate locally from a plurality of sensors said raw data or said processed data to a central communication interface operating from an intrinsically safe housing; create a data log respecting sensor performance or the identity and concentration of said gases; detect the presence and relative signal strength of any suitable cellular wireless long-distance service, and, based on said signal strength, automatically select between said cellular wireless long-distance means and any suitable satellite transponder long-distance service; wirelessly transmit long-distance over the Internet said raw data or said processed data, using either said cellular or satellite wireless long-distance service, to a location off-site; receive said raw data and said processed data at a specified IP address and securely portray through an Internet serving call centre at least a portion of said processed data respecting each said gas identified.
