Gas/oil well monitoring system
First Claim
1. A system for monitoring a gas/oil well, comprising:
- a monitoring unit at a well head, the monitoring unit including a wireless monitor transceiver consuming power at a safe level for avoiding an explosion risk and further including a gas tight box for housing sensor processing electronics, said wireless monitor transceiver located outside of said gas tight box;
a relay unit including a wireless relay transceiver communicating with the wireless monitor transceiver of the monitoring unit and further including a telephone communication link; and
a host interface communicating with the relay unit through the telephone communication link.

Abstract
A system for monitoring a gas/oil well is provided with a monitoring unit, a relay unit and a host interface. A monitoring unit collects data regarding the status of the gas/oil well and wirelessly transmits that data to a relay unit. The relay unit, in turn, connects to a host interface using cellular communications and transmits the data. The monitoring unit can transmit information on demand or after an alarm condition is sensed. In either case, the monitoring unit is normally in a sleep mode. The relay unit can request information from the monitoring unit or respond to a wake up transmission sent to it from either the host interface or monitoring unit. The host interface receives data from the relay unit and then informs an end user of that data.

8. A method of communicating to and from an explosive environment, comprising:
-
situating a first transceiver in said explosive environment, said transceiver operating at a power level which is below the level defined as dangerous within said explosive environment; situating a second transceiver proximate to but outside of said explosive environment, said second transceiver operating at a power level which is above the level defined as dnagerous within said explosive environment; and communicating with said first transceiver through said second transceiver from a location outside of said explosive environment and not proximate to said explosive environment.
