Description
BACKGROUND OF THE DISCLOSURE [0003] This section is intended to introduce the reader to various aspects of the art that may be related to various aspects of the present disclosure. The following discussion is intended to provide information to facilitate a better understanding of the present disclosure. Accordingly, it should be understood that statements in the following discussion are to be read in this light, and not as admissions of prior art.

-2[0004] Atmospheric Monitoring Systems, herein after referred to as AMS, and their requirements are thoroughly described in The Mine Safety Health Administration’s 30 CFR § 75.351.
[θθθδ] http://www.msha..gov/30CFR/75.351 .htm [0006] Historically, AMS consisted of gas monitors connected over a hardwired network all communicating to a central area as described in the above requirement in section (b)(1). As the mine expanded and additional monitors were needed, lengths of cable were added to facilitate communications and power to new monitoring locations. As technology progressed, wireless and battery powered solutions became available. Extensive lengths of cable providing data and power were no longer needed. Mines now have the option of running a hardwired system or a hybrid of both hardwired with wireless. This becomes especially effective when the mine monitoring requirement consists of both permanent and temporary monitoring needs. Areas along the beltways are typically unchanging and are best suited for hardwired monitoring where developing areas of the mine are better suited for a wireless/battery powered solution. Aside from the existing hardwired network, a wireless communication network is still needed to transmit data from the wireless monitors to the designated central area. This could be served with a device that acts as an access point for the wireless monitor data to enter the existing hardwired network or an entirely separate true wireless network such as Strata Products Worldwide, LLC’s CommTrac system.
[0007] As taken from section (c)(2) of the above requirement, an AMS must have the ability to “Automatically provide visual and audible signals at the designated surface location when the carbon monoxide concentration or methane concentration at any sensor reaches the alert level as specified in § 75.351 (i). These signals must be of sufficient magnitude to be seen or heard by the AMS operator.” [0008] The detail of importance in this section is the mention of “methane”. Traditional AMS hardwired systems offer methane monitoring but only in the 05% by volume range using catalytic bead technology. Methane concentrations above 5% will cause catalytic technology to be permanently damaged. In the event of a disaster and mine ventilation is lost, methane levels can easily exceed 5% concentration. Existing technology

-3cannot provide atmospheric information that is critical during rescue efforts. No wireless or hardwired option exists to fulfill this need. Furthermore, the available wireless gas monitoring devices only offer carbon monoxide as a detectable gas and only in the 100 PPM maximum range.
[0009] As taken from section (c)(4) of the above requirement, an AMS must have the ability to “Automatically provide visual and audible signals at all affected working sections and at all affected areas where mechanized mining equipment is being installed or removed when the carbon monoxide, smoke, or methane concentration at any sensor reaches the alarm level as specified in § 75.351(1). These signals must be of sufficient magnitude to be seen or heard by miners working at these locations. Methane signals must be distinguishable from other signals.” [0010] Traditional AMS hardwired systems offer this ability through a hybrid monitor/alarming unit although no wireless options for this requirement exist currently. Mines are often forced to ran a separate control network if using a wireless monitoring solution to satisfy the section alarming requirement.
[0011] Similar to mines, oil and gas rigs need to monitor the atmosphere for dangerous levels of various gases without the need of cables and wiring cluttering the rig. In places such as oil and gas rigs, there is also the risk of dangerous gases and the need to monitor the atmosphere for these dangerous gases. Typically, gas monitors were connected by cabling and wiring throughout the rig has been used to monitor dangerous gases on a rig. The presence of all of these cables and wires distributed throughout a rig creates the problem of properly organizing and positioning the cables and wires so they do not interfere with the operation of the rig nor can be damaged so that connection is lost with the monitor during operation. If connection is lost with a monitor, then the monitor as well as the entire length of the cable or wire that connects the monitor to a remote station for monitoring must be examined to correct the loss of communication with the monitor. Such cabling and wiring could extend quite a long distance and be located in difficult positions to examine and can become a significant issue to correct.

-4[0012] In addition, in a mine, it is important to be able to track and communicate with a miner in ideally the most unobtrusive way possible. Besides the mine environment being a dangerous place in and of itself, the more equipment a miner carries, the more difficult it is for the miner to perform his functions and move through the mine. What is desired is a simple way to alert a miner of a dangerous or emergency condition, as well as for the miner to inform a remote station of the miner's condition and the miner's location.
[0013] To further provide for the safety of a miner, the miner is required to carry a light, such as a cap lamp that the miner wears on his head, as well as is required to be tracked in the mine, and also be protected from contact with machinery so as not to be injured by the machinery by accidentally contacting the machinery during operation. The latter protection is afforded with the use of a proximity device earned by a miner and proximity sensors positioned on machinery which, when determining that a proximity device earned by a miner is within a predetermined location of the proximity sensor, the machine is turned off so the miner is not injured. As the light is already required to be carried by a miner, and the proximity device is commonly earned by a miner, it would be desirable to combine tracking with these functions since they are already present on the miner.
[0014] To provide communication to and from the miner to inform the miner of important information or to track the miner or to enable the miner to communicate with the remote station, communication networks are critical throughout the mine. Since the mine is a very difficult environment for communication networks, redundancy, as well as data networks that ideally work best to transmit data, and voice networks thatddeally work best to transmit voice bidirectionally, in which also can transmit data, and work in combination are desired.

-16signal from the housing 12 that the gas sensor portion 16 has sensed of either the first or second gas. The monitor 10 comprises at least one input 54 for connection to a remote device which provides a status signal regarding the remote device which is transmitted by the wireless communication portion 20 from the detector. The monitor 10 comprises a processor 22 disposed in the housing 12, powered by the battery 14 and in electrical communication with the wireless communication portion 20, the input 54, sensor portion and battery 14.
[0064] The present disclosure pertains to a method for monitoring gases in a mine.
The method comprises the steps of detecting with a gas sensor portion 16 a first gas and at least a second gas different from the first gas in the mine, the gas sensor portion 16 powered by a battery 14 and in electrical communication with the battery 14, the gas sensor portion 16 and the battery 14 disposed in the housing 12. There is the step of emitting with an alarm portion 18 powered by the battery 14, disposed in the housing 12 and in electrical communication with the battery 14 a visual alert and an audible alert when the gas sensor portion 16 senses that either the first or second gas is above a predetermined threshold. There is the step of sending with a wireless communication portion 20 disposed in the housing 12, powered by the battery 14 and in electrical communication with the battery 14 and the sensor portion a wireless signal from the housing 12 that the gas sensor portion 16 has sensed either the first or second gas.
[0065] The present disclosure pertains to a monitor 10 for gases in a mine, as shown in figure 13. The monitor 10 comprises a housing 12. The monitor 10 comprises a battery 14 disposed in the housing 12. The monitor 10 comprises a gas sensor portion 16 powered by the battery 14 and in electrical communication with the battery 14 which detects a first gas and at least a second gas different from the first gas in the mine. The monitor 10 comprises a terminal portion 58 that has two states, an output configuration state in which an output signal is sent from the processor 22 to a first device 60, such as the audio alarm 30, as shown in figure 4, and an input 54 configuration state in which an input 54 signal is received from a second device 62, such as a field switch, as shown in figure 7. The monitor 10 comprises a wireless communication portion 20 disposed in the housing 12, powered by the battery 14 and in electrical communication with the battery 14 and the sensor portion, which sends a wireless signal from the housing 12 that the gas sensor portion 16 has sensed of either the first or

- 17second gas. The monitor 10 comprises a processor 22 disposed in the housing 12, powered by the battery 14 and in electrical communication with the wireless communication portion 20, alarm portion 18, sensor portion and battery 14.
[0066] The present disclosure is related to a system 64 for monitoring gases underground, as shown in figure 13. The system 64 comprises a monitor 10 which detects a gas located in a tunnel underground and determines a gas value of the gas. The monitor 10 has an audio alarm 30 and a visual alarm 32 which is activated what the detected gas is above a predetermined value, and a transmitter which transmits the gas value. The system 64 comprises a wireless telecommunications network 66 on which the gas value is transceiver 48 from the monitor. The system 64 comprises a remote station 68 which receives the gas value from the network 66. The transceiver may receive a signal from the network to change a set point for an alarm condition for the gas to be determined by the monitor.
[0067] In the operation of the disclosure, and with reference to figure 13, the system is a battery 14 powered CommTrac enabled gas monitor 10 to fulfill the MSHA requirements identified above and offer a truly unique solution. To meet the requirement of section (c)(2), a visual and audible alarm has been integrated into a Trolex Sentro gas detector 70 equipped with a battery 14 pack and CommTrac Interface module 72 (CIM), as shown in figures 3 and 4. The alert points will allow for a completely wireless gas monitor 10 that has the ability to alert personnel in the working zones in accordance with section (c)(2). The gas concentration alert and alarm points as mentioned in sections (i)(2) and (i)(3) will trigger the integrated monitor 10 audible and visual alarms via two unique output options. The first output 74 will trigger the visual alarm 32 when an alert level is reached. Different color visual alarms 32 will be available for different gases. The second output 76 will trigger the audible alarm when an alarm level is reached. If the monitor 10 is not being configured as a section alarm, the outputs 56 can be used as remote output to control connected devices. Aside from just methane and carbon monoxide, carbon dioxide, hydrogen sulfide, nitrogen dioxide, chlorine, oxygen, nitric oxide, and hydrogen will also be available for detection. Methane will be detectable over the entire volume range using an infrared technology based sensor as opposed to the current catalytic technology. Aside from full range capabilities, infrared technology is not affected by high concentrations. Carbon monoxide will be

2018208722 26 Jul 2018
-18available in 1000 PPM maximum range. Hydrogen discriminate carbon monoxide detection will also be supported along with nitrogen dioxide filtered carbon monoxide detection capabilities. Open wireless protocols such as 802.11 will also be a supported means of communication aside from the CommTrac mesh infrastructure. Ultimately, the wireless battery 14 powered gas monitor 10 can offer a complete and single system solution to the MSHA AMS requirement. The features outline above are truly unique and the first of their kind. The CommTrac network 66 already exists and is available from Strata Products Worldwide, LLC, Sandy Springs, Georgia.
[0068] In regard to figure 5, there is shown a theory of operation of the present disclosure. First, the monitor 10 is turned on and powered up. Then, the necessary software and functionality is written into the static registers of the monitor 10 for operation. From that point, stable operation of the monitor 10 proceeds from an idle state. From the idle state, the processor 22 requests of the gas sensor portion 16 a status report every five seconds. The gas sensor portion 16, if there is no warnings or alarms identified, reports back to the processor 22 that there are no warnings or alarms. If there is a warning state or alarm state or calibration state that occurs, the processor 22 takes the information that it has received from the gas sensor portion 16 and prepares this information to be sent through the transceiver 48 and out the antenna 52 to the CommTrac network 66 and ultimately to the central monitoring station. In addition, if the processor 22 does not receive a response from the gas sensor portion 16 within the interval timer period after the request for sensor status has been issued, then the processor 22 also transmits through the CommTrac network 66 a signal that communication has been lost with the gas sensor portion extending. When the central monitoring station receives the signal that communication has been lost with the gas sensor portion 16, steps are then taken to investigate and review the gas sensor portion 16 to correct the problem that is causing the failure of the gas sensor portion 16 to respond to the processor 22.
[0069] In regard to figure 3, there is shown a block diagram of the monitor 10. The
CommTrac transceiver 48 is in electrical connection over a UART connection to the antenna 52. The CommTrac transceiver 48 is also in communication with the battery 14 power supply through which power from the mine power supply is available. There is feedback protection connected to the external port connectors connected to the mine power supply. The battery 14
10262892_1 (GHMattera) P98209.AU.1
2018208722 26 Jul 2018
-19power supply is also connected at 3.3 V to the output 56 ports to provide power to them. There are two input 54 ports and two output 56 ports. There is also a video alarm 32 and an audio alarm 30. There is input/output protection connected to the battery 14 power supply, the CommTrac transceiver 48 and the input and output ports.
[0070] In the operation of the disclosure, reference is made to the parts list below which identifies the parts by model number and vendor from which they can be obtained. The operation of the parts listed below, as individual components, is well known.
[0071] The gas sensor portion 16 itself is an off-the-shelf Trolex TX 6351/2 Sentro 1 universal gas detector 70. It has the ability to monitor several different gases at once. For a given gas value identified by the detector, this value is provided to the processor 22, which is a PIC 24 processor 22. The processor 22 converts the gas value into a packet form which can be transmitted wirelessly. The gas value provided from the detector 70 to the processor 22 is across a standard serial connection. It is received at pin header 6 of the processor 22, as shown in figures IB and 2A-2E. The detector 70 provides a specific gas value for a given gas being monitored by the detector 70 in response to a request sent by the processor 22 from its pin header 4. The requests for the different gases, occurs one at a time in sequence, and then is continually repeated so that the different gases being monitored by the detector 70 are continually reviewed over time by the processor 22.
[0072] The packet produced by the processor 22 for a given gas being monitored, is then sent from PIC 24 to the transceiver 48, CC 1110, as shown in figure 1 A, where it is received at its pin 34 input 54. From the transceiver 48, the packet signal is then provided to the amplifier 50 CC 1190 which boosts the signal and then transmits it through its antenna 52. The wireless transmitted packet having the value of the gas is then transmitted over the existing CommTrac network 66. The PIC 24, CC 1110, CC 1190 and internal antenna 52 form and define the CIM 72 [0073] Signals can also be received by the antenna 52 of the amplifier 50, which modulates the received signal, and provides it to the transceiver 48 where it is outputted through transceiver 48 pin 35 back to the processor 22 that receives it at pin header 6. The
10262892_1 (GHMatters) P98209.AU.1
2018208722 26 Jul 2018
-20signal that is received by the monitor 10 can be a signal to change the set point by the processor 22 for an alarm condition for a given gas being monitored.
[0074] In addition to the gas value that is provided by the gas detector 70 to the processor 22, along the same serial connection and same pin attachments, an alarm signal for a given gas is provided to the processor 22 when the monitor 10 gas is above a certain predetermined value. The processor 22 receives the alarm signal and then activates an audio alarm 30 as well as a visual alarm 32. The audio alarm 30 is loud enough to be heard by miners in the vicinity of the monitor 10. The visual alarm 32 is formed by a plurality of LED lights that are illuminated when the alarm occurs. A different sequence of colors, or simply different colors are illuminated for a corresponding type of gas, so for instance methane would have a different set of LED lights or different colors of lights activated then the LED lights activated for carbon dioxide. In addition, if so desired, the audio alarm 30 can be set to have a different tone or frequency corresponding to the type of gas detected if desired. The processor 22 also transmits an alarm signal through the transceiver 48 to the CommTrac network 66.
[0075] The processor 22, detector, transceiver 48 and amplifier 50 are all powered by battery 14 through a standard battery 14 selection circuit 74. Also available is an external power interface 76 that can receive wired electricity from the mine external power source.
[0076] The wireless communication portion 20 that has been added to the gas detector contains a microcontroller - a CC1110 which is in electrical communication with thee PIC24 microcontroller. The PIC24 is the center of the monitor in that it communicates with the detector’s microcontroller to obtain sensor information and also communicates with the CC1110 to send and receive data over the CommTrac network 66.
[0077] The software in the PIC24 polls the detector’s microcontroller, here the Trolex
PIC 18, on a continuous basis for sensor information. It packages this sensor information and sends it to the CC1110 to be transmitted over the CommTrac system at configurable intervals. The software also monitors the information from the PIC 18 on the Trolex detector for alarms
10262892_1 (GHMatters) P98209.AU.1
2018208722 26 Jul 2018
-21and if any are generated, a message will be sent to the CC1110 for transmission via the CommTrac network 66.
[0078] The software can also be configured to use the two available I/Os 80, as shown in figures 12 and 13. These I/Os 80 can either be connected to audible and visual alarms 30, 32 - in which case, they would be activated if an alarm condition is reported by the detector 70, as shown in figures 6 and 8. Alternatively, these I/Os 80 can be used as inputs which will cause the software to send a message over CommTrac if the circuit on the I/O line is broken, (e.g. a belt stop switch), as shown in figures 7 and 9. In between these activities, the software will put the CC1110 and the PIC24 into sleep mode in order to conserve power.
[0079] The CC110 transceiver 48 receives the message from the PIC 24 and places it into the transmit queue. The CC1110 is then listening for a beacon message from one of the CommTrac Communication Nodes (backbone of the network 66). When it hears a beacon message it will select a data slot to transmit the message. During the chosen slot the message is sent and it waits to receive an ack from the Communication Node during the acknowledgement slot. If the ack is properly received the message will be removed from the transmit queue. If it doesn’t receive an ack then the message is resent during the next beacon cycle. The CC1190 is typically only used to amplify the transmit and receive signal to allow for greater distances when transmit/receiving.
[0080] The AV unit may be mounted beneath a Wireless Sentro Gas detector 70 with the communication portion 20 with hard wiring between the two units, as shown in figure 11. The sound and light alarms will be activated by switching the battery 14 supply on and off. This can be controlled by software allowing the option of pulsed light and sound alarms.
[0081] The same two outputs of the pic 24 that are used to drive the audible and visual alarms 32 can be configured using software to also be inputs 54. The configuration allows the states of various input devices such as pull cords, emergency stops buttons or fault switches to be transmitted through the CommTrac network 66 to the surface for monitoring. The states of the switches are often unrelated to the gas monitoring data that the sensors are transmitting, but the sensors are typically located in remote areas in the mine
10262892J (GHMatters) P98209.AU.1
2018208722 26 Jul 2018
-22where other communication networks do not exist. It is quite attractive to give the mine the option of monitoring a remote switch through a communication network 66 that is available in remote areas. Alternately, if the apparatus is not equipped with an audible or visual alarm 30, 32, the available output 56 can be used to drive a low current consumption device that may also be located remotely in the mine where the CommTrac network 66 is available.
[0082] In regard to figure IB, the screw terminal corresponds to the description of figures 8 through 10 can connect to a given output 56 or input 54 depending on the configuration. The pin headers connect to the gas detection portion, here specifically the Trolex assembly card. The program headers connect to the pic 24 through J 3 into the CC1110 through J 5.
[0083] In regard to figures 2A-2E, depending on whether the apparatus is in an input configuration or an output configuration, the pic 24 through L out 1 and L out 2 communicates to control out 1 and control out 2, respectively, of the output control section which then is provided, for instance through output 1 and output 2, respectively, to the audio alarm 30 and the video visual alarm 32, respectively, if in the output configuration. When in the input 54 configuration, the outputs 56 are reversed and are inputs 54, so the pic 24 receives input 54 signals from input 1 (instead of output 1) and from input 2 (instead of output 2) and these input signals follow a reverse direction back to the pic 24 from that described above in the output direction, that is to control out 1 and control out 2, respectively, to L out 1 and L out 2, respectively, of pic 24.
[0084] As explained above, and with reference to figure 6, when in the output configuration, output 1 is used for the visual alarm 32, and output 2 is used for the audible alarm. In the output mode, and with reference to figure 9, terminal 1 has a voltage, for instance 1.2 V, connected to the visual alarm 32 load, and terminal 2 is connected to ground and the visual alarm 32 load. The 1.2 V energizes the visual alarm 32 when the switch is closed. Similarly, output 3 has 1.2 V and energizes the audible alarm, and either terminal 5 or terminal 2 is connected to ground and the audible alarm. In this configuration, the operation of the alarms is as described above.

-23[0085] If the monitor 10 is desired to be in the input 54 configuration, as shown in figure 7, the monitor 10 is used to monitor 10 whatever the device, such as a field switch or pull cord or emergency stop, is connected to it. Here, terminal 1 has 1.2 V on it and is connected to the device being monitored, here a field switch, as shown in figure 8. Terminal 2 is connected to ground and to the field switch. When the switch is closed, pic 24 senses the 1.2 V going to ground and produces a field switch signal that is then converted by the pic 24 into a form that can be sent wirelessly by the apparatus, as described above in regard to the description of the gas value being sent wirelessly from the apparatus.
[0086] Similarly, and with reference to figure 8, a second device 62, such as a pull cord, can be in electrical connection with terminal 3 having 1.2 V. Terminal 5, which is ground, is electrically connected to the second device 62, such as the pull cord, and the same description is applicable in sending a signal involving the pull cord being pulled occurs as described for the field switch connected to terminals 1 and 2.
[0087] As shown in figure 10, the terminal is a six position terminal disposed on the housing 12 and accessible from outside the monitor 10. Terminal 1 is either the first output 74 or input, terminal 2 is ground, terminal 3 is the second output 76 or input, terminal 4 is electrically connected to the battery 14, terminal 5 is ground, and terminal 6 is connected to external power for the apparatus to receive external power.
[0088] Accordingly, when in the input 54 configuration, which is established prior to the monitor 10 being positioned at a desired location in the mine, input 1 and input 2 of the terminal can receive signals through hardwired connections with various types of devices, to allow for the devices to be monitored. In the output configuration, the same terminals having input 1 and input 2 are now output 1 and output 2 and are configured as described above, for the pic 24 to send alarm signals to activate the audible and visual alarms 30, 32.
[0089] The following are features of the apparatus.

[00130] The present disclosure pertains to a system 64 for monitoring gases on an oil or gas rig, as shown in figure 13. The system comprises a monitor 10 which detects a gas at the rig and determines a gas value of the gas. The monitor 10 having an audio alarm 30 and a visual alann 32, which is activated when the detected gas is above a predetermined value, and a transceiver 48 which transmits the gas value. The system 64 comprises a wireless telecommunications network 66 on which the gas value is transmitted from the monitor 10. The system 64 comprises a remote station 68 which receives the gas value from the network 66.
[00131] The remote station 68 may include a receiver which receives the gas value from the network 66, a processor 22 in communication with the receiver which receives the gas value from the receiver, and a display 38 in communication with the processor 22 on which the processor 22 displays an alarm indication when the gas value is above a predetermined level.
[00132] The present disclosure pertains to a remote station 68 which receives gas values of gas monitors from a wireless network 66. The remote station 68 comprises a receiver which receives the gas values wirelessly from the network 66. The remote station 68 comprises a processor 22 in communication with the receiver which receives the gas values from the receiver. The remote station 68 comprises a display 38 in communication with the
10262892_1 (GHMatters) P98209.AU.1
2018208722 26 Jul 2018
-31processor 22 on which the processor 22 displays an alarm indication when the gas value is above a predetermined level.
[00133] The station 68 may include a housing 12 and the processor 22 and the receiver are disposed in the housing 12 and the display 38 is disposed on a face of the housing 12.
[00134] When the monitors 10 are used on an oil or gas rig, the monitors 10 are placed at various locations throughout the rig. A single communication node, such as a CommTrac node is placed with the central control station on the rig, where all of the monitors 10 are monitored. On the rig, since there are no seams or earth to interfere in any way with the transmission and reception of signals by the monitors 10, typically just a single communication node 206 is all that is needed for communication with the monitors 10. The communication node 206 essentially forms a hub network 66 with the monitors 10. The network 66 can be a CommTrac network 66 where data signals are sent over the network 66 as described above between the CommTrac communication node 206 and the monitors 10.
[00135] In one embodiment, as shown in figure 16, the receiver of the remote station 68 is part of the transceiver 48 of the CIM 72 described above, disposed in a housing 12 of the remote station 68. The gas value from each of the monitors 10 on the rig is received over the CommTrac network 66 at the CIM 72. The CIM 72 provides the gas values the CIM 72 has received to the Moxa 230 Miineport, as described above in regard to the shared power supply 200, which converts the serial data signal from the CIM 72 into an Ethernet format signal. The Ethernet signal is provided to a switch 236 which in turn provides it to a Beagle Bone PC 232 through the switch 236 that prepares the signal for a modbus PLC 234. The PC 232 provide the prepared signal through the switch 236 to the PLC 234 which then causes the prepared signal to be displayed on the display 38 on the housing 12 face, as shown in figure 17.

There is the step of powering the data portion 224 and the wireless portion 223 with a power supply portion 200 in electrical communication with the data portion 224 and the wireless portion 223.
[00142] Referring to figure 14B, there is shown a schematic diagram focusing on the shared power supply 200 that is shared by the wireless network 202 and the wireless data network 204 which is separate and distinct and independent from the wireless network 202, all of which is found in a single communication node 206, such as a StrataConnect node 206 A. The wireless network 202 may be that wireless network 202 as described in U.S. application 14/290,755, incorporated by reference herein, which supports and provides for bidirectional voice and data communication. The data network 204 may be the CommTrac network 66 sold by Strata Products Worldwide, LLC, Sandy Springs, Georgia. The data network 204 may provide bidirectional data communication, as well as tracking of miners and vehicles and various devices throughout the mine. The node 206 receives data from the data

2018208722 26 Jul 2018
-34network 204, processes the data so the data can be transmitted on the wireless Wi-Fi voice network 202 with the fibers 222, and then transmits the processed data on to the remote station 68, either through the Wi-Fi network 202 with the fibers 222.
[00143] A node 206 having the functionality of the CommTrac network 66 and the wireless network 202 receives power from the mine power supply 208 at power input 210. The power from the mine power supply 208 is at between 12 and 48 VDC. The power input 210 is electrically connected to a POE injector 212 which converts the power to 10 VDC to power the components inside the node 206. Power from the injector 212 at 10 VDC and 1 amp is provided to the first radio 218 and second radio 220 over a Cat5/Ethemet connection connected to each radio. Power from the injector 212 at 10 VDC and 500 mA is provided to the switch 221 in the node 206. Also connected to the switch 221 are external fibers 222 through external fiber connectors 223 over which transmission and reception of communication signals occur. The injector 202 powers the data connection portion 224, here preferably the CommTrac portion 224, such as a CIM 72 that communicates with the CommTrac network 66 and a data converter 226, such as a serial to Ethernet converter 226, and specifically a Moxa 230, at 3.3 V and 500 mA.
[00144] The CommTrac portion 224 connects with the serial to Ethernet converter 226 through a UART connection at 3.3 VDC and at 115 kb per second which provides the data signal received by the CommTrac portion 224 to the serial to Ethernet converter 226. The serial to Ethernet converter 226 converts the data signal received by it from the CommTrac portion 224 into a form that can then be transmitted through the fibers 222 or through the radios and provides the converted signal to the switch 221. The switch 221 then transmits the converted signal that was originally received by the CommTrac portion 224 through the fibers 222, or if the fiber connection is not available, through the radios.
[00145] In addition, the node 206 may also receive power from another node 206 through a Cat 5 connection 228 and also provide power to another node through a Cat 5 connection 228 to form a daisy chain of nodes 206. Each of the Cat 5 power connections 228 are RJ45 connectors. The power level of the Cat 5 connections 228 coming in or going out of

2018208722 26 Jul 2018
-35the node 206 is the same as the power level received by the node 206 from the mine power supply 208.
[00146] Figure 14B shows a non-IS node 206. Figure 14C shows a node 206 that is IS. The node 206 operates essentially the same as the node 206 of figure 14B, except that certain power levels are different, as indicated, and the external Cat 5 connections 228 are omitted.
[00147] The present disclosure pertains to a miner communicator 298 in a communications network 66, as shown in figure 15. The communicator 298 comprises a housing 12. The communicator 298 comprises a processor 22 disposed in the housing 12. The communicator 298 comprises a transceiver 48 disposed in the housing 12 and in communication with the processor 22 and the network 66 to send to and receive from the network 66 only data but not including text. The communicator 298 comprises an input 300 disposed on the housing 12 and in communication with the processor 22 which provides a trigger signal to the processor 22. The communicator 298 comprises an alarm 302 in contact with the housing 12 and in communication with the processor 22 that is activated by the processor 22 when an alarm 302 signal is received by the transceiver 48. The communicator 298 comprises a tracking portion 310 disposed in the housing 12 which provides a tracking signal that is transmitted by the transceiver to the network from which the location of the housing in the mine is determined along with an ID of the communicator 298. The transceiver 48 transmits the ID and tracking signal to the network 66 to a communication node 206, ideally the closest node 206, and then to the remote station 68. The tracking portion 310 may be part of the CC 1110. The CC 1110 is an off the shelf transceiver that is. purchased and also provides tracking ability by measuring the signal strength of the CommTrac node 205 ideally closest to the transceiver 48, whose location is known and stored in a server in the remote station 68. The signal strength is sent through the network 66 to the server, and using triangulation by the server, which receives the signal strength, determines the location of the transceiver 48, as is more fully explained below and is already part of the CommTrac network 66.
[00148] The input 300 may be a single button 304. The alarm 302 may be a first LED 306 that illuminates when the alarm 302 signal is received by the transceiver 48. The alarm
10262892.1 (GHMatters) P98209.AU.1
2018208722 26 Jul 2018
-36302 may be a plurality of LEDs 306 which is illuminated when the alarm 302 signal is received by the transceiver 48. There may be no display 38 and no key board or key pad, only the single button 304.
[00149] The trigger signal may be a fixed shape signal whose duration corresponds to how long the button 304 is activated. The alarm 302 may be activated only when an alarm 302 signal is received during to listening intervals in a listening period by the transceiver 48. The activation of the button 304 may cause the processor 22 to produce an indicator signal to the network 66 through the transceiver 48 corresponding to the activation length and activation frequency of the button 304.
[00150] The transceiver 48 may have its settings changed by the processor 22 when the communicator 298 is within a predetermined distance of a communication node so the transceiver 48 is not saturated by the communication node. When the communicator 298 transitions from an area of surface communication nodes to only underground communication nodes, the processor 22 may transmit to the network 66 through the transceiver 48 a check in message that the communicator 298 is present in the mine.
[00151] The present disclosure pertains to a method for communicating with a miner in a mine. The method comprises the steps of sending an alarm 302 signal wirelessly through a wireless communication network 66 to a miner communicator 298 carried by a miner in the mine. The communicator 298 is only able to receive data but not voice. There is the step of receiving the alarm 302 signal by the communicator 298. There is the step of activating an alarm 302 of the communicator 298 by a processor 22 of the communicator 298 in response to the communicator 298 receiving the alarm 302 signal. There is the step of activating a button 304 of the communicator 298 to cause the transmitter to transmit from the communicator 298 to the network 66 an indicator signal regarding the miner’s status, and with the indicator signal is an id of the communicator 298 and information associated with the position of the communicator 298, The communicator 298 does not have a display 38 or a keyboard.
[00152] The communicator 298 for communicating with a user, such as a miner, provides for limited but important information transfer between the user and a monitoring
10262892..1 (GHMatters) P98209.AU.1
2018208722 26 Jul 2018
-37station. This limited information transfer is bidirectional to provide the remote station 68 with information about the user, and to provide the user with critical emergency alert information. The communicator 298 is very lightweight so that it is easily carried or worn by the user and is battery powered.
[00153] The communicator 298 sends position messages that report the ID, the cun-ent position data by providing the signal strength of signals received by the communicator 298 from a closest operable communication node 206 in the mine to the communicator 298, the ID of the closest communication node 206 and possibly battery level, and event information at predetermined intervals wirelessly over a network 66 to the remote station 68 so the miner can be tracked. The network 66 can be the CommTrac network 66 or the StrataConnect network 66, which is comprised of the CommTrac network 66 and a WiFi network 66, as described above. The communicator 298 will listen for any messages sent to it at different predetermined intervals.
[00154] The communicator 298 includes a processor 22, such as a PIC 24, and a transceiver 48, such as a CC1110, and can be the CIM 72, the operation of which is already described above in regard to the operation of the wireless gas monitor 10. The CommTrac network 66 is synchronized with the communicator 298 so that when the communicator 298 sends information or receives information at the appropriate predetermined intervals, the CommTrac network 66 knows to send or receive the respective information in the appropriate timeframe.
[00155] When the communicator 298 is within a predetermined distance of a Commtrac node, the transceiver 48 is attenuated by about 10 db, and its RSSI values are adjusted upward by the same amount. This is to deal with the condition of a CommTrac node being very close to the communicator 298 and saturating the transceiver 48. The transmission power of the transceiver 48 is also reduced by 10 db if the communicator 298 is close to the CommTrac node so as to prevent saturating the CommTrac node transceiver 48.
[00156] During listening periods by the communicator 298 to receive information, a mine-wide alert state bit is used to determine that an emergency condition exists. This bit
10262892_1 (GHMatters) P98209.AU.1
2018208722 26 Jul 2018
-38must be detected in at least two listening intervals within a predetermined listening period to be considered valid. By requiring information received by the communicator 298 in at least two listening intervals in a predetermined listening period to have this bit, it reduces the possibility of false alarms. When none of the listening intervals in the predetermined listening period do not have this bit, the alert state is considered no longer present.
[00157] A light on the apparatus will flash, preferably in a distinct pattern, when the mine-wide alert is recognized by the communicator 298. After a mine-wide alert is recognized; the miner will press a button 304 one, two or three times to indicate the miner's status. For instance, if the button 304 is pushed once, it means the miner is fine. If the button 304 is placed twice in succession, it means the miner is trapped. If the miner pushes the button 304 three times in succession, it means the miner is injured. The miner can push the button 304 twice, then wait a few seconds and push it again three times to indicate he is trapped and injured. The communicator 298 will send an emergency response acknowledgment with the position message to indicate the miner's response. The light may be several LEDs 306 of different color.
[00158] A quick press on the button 304 performs a communication check and battery status update. Holding down the button 304 for an extended period of time or multiple presses of the button 304 during a short period of time is used to trigger an emergency message. Holding down the button 304 for an extended period of time shall remove this condition. Two quick presses of the button 304 turn the LED 306 flasher on or off. In response to a mine-wide alert message, one, two or three presses indicate the user's response condition.
[00159] One bit of received information in a listening interval is used to indicate if the CommTrac node is a surface node. Transitioning from an area of surface nodes to only underground nodes triggers the apparatus to issue a check in message. A checkout message is transmitted when transitioning in the other direction-transmitting a checkout message when only surface nodes are heard and the apparatus is formally in a check in state. The apparatus only waits for the network 66 level acknowledgment that indicates the check in/out message made it successfully to the CommTrac node. The apparatus does not need to wait for check in/out acknowledgment.
10262892_1 (GHMatters) P98209.AU.1
2018208722 26 Jul 2018
-39[00160] For a communication check, after the button 304 is quickly pressed, the LEDs 306 flash once immediately to provide feedback. After a short pause, a series of 1-3 LED 306 flashes indicate battery life (1 - needs replacing soon, 2 - middle life, 3 - new). After another pause, a second series of flashes indicate strength of node (1 - weak, 3 - strong). The LEDs 306 will flash in a pattern indicative of an emergency state. For example, a - flash with pauses in between will indicate an emergency state. The LEDs 306 will flash in a basic pattern used only for visual warning. During a mine-wide alert message, the LEDs 306 blink in a pattern making it very clear the apparatus is in an alert state.
