Gas Monitor, System and Method

A monitor of a communication network for gases in a mine comprising:

• a housing;
• a battery disposed in the housing;
• a gas sensor portion powered by the battery and in electrical communication with the battery which detects a first gas and at least a second gas different from the first gas in the mine;
• a wireless communication portion disposed in the housing, powered by the battery and in electrical communication with the battery and the sensor portion, which sends a wireless signal from the housing to the network in the mine that the gas sensor portion has sensed of either the first or second gas;
• at least one input for connection to a remote device which provides a status signal regarding the remote device which is transmitted by the wireless communication portion from the detector;
• and
• a processor disposed in the housing, powered by the battery and in electrical communication with the wireless communication portion, the input, sensor portion and battery.

A method for monitoring gases in a mine comprising the steps of:

• detecting with a gas sensor portion a first gas and at least a second gas different from the first gas in the mine, the gas sensor portion powered by a battery and in electrical communication with the battery, the gas sensor portion and the battery disposed in the housing;
• emitting with an alarm portion powered by the battery, disposed in the housing and in electrical communication with the battery a visual alert and an audible alert when the gas sensor portion senses that either the first or second gas is above a predetermined threshold;
• and
• sending with a wireless communication portion disposed in the housing, powered by the battery and in electrical communication with the battery and the sensor portion a wireless signal from the housing that the gas sensor portion has sensed either the first or second gas.

A monitor of a communication network for gases in a mine comprising:

• a housing;
• a battery disposed in the housing;
• a gas sensor portion powered by the battery and in electrical communication with the battery which detects a first gas and at least a second gas different from the first gas in the mine;
• a terminal portion that has two states, an output configuration state in which an output signal is sent from the processor to a first device, and an input configuration state in which an input signal is received from a second device;
• a wireless communication portion disposed in the housing, powered by the battery and in electrical communication with the battery and the sensor portion, which sends a wireless signal from the housing to the network in the mine that the gas sensor portion has sensed of either the first or second gas;
• and
• a processor disposed in the housing, powered by the battery and in electrical communication with the wireless communication portion, alarm portion, sensor portion and battery.

A system for monitoring gases underground comprising:

• a monitor which detects a gas located in a tunnel underground and determines a gas value of the gas, the monitor having an audio alarm and a visual alarm which is activated what the detected gas is above a predetermined value, and a transceiver which transmits the gas value;
• a wireless telecommunications network in the tunnel on which the gas value is transmitted from the monitor;
• and
• a remote station which receives the gas value from the network.
