CROSS REFERENCE TO RELA __________________ l'ED APPLICATION
[0001] The present application is a divisional application of Canadian Patent Application No. 2,866,032 filed on October 3, 2014.
FIELD OF THE INVENTION
[0002] The present invention is related to monitoring of gas where the value of the gas is transmitted wirelessly. (As used herein, references to the "present invention"
or "invention"
relate to exemplary embodiments and not necessarily to every embodiment encompassed by the appended claims.) More specifically, the present invention is related to monitoring of gas in an underground environment or an oil or gas rig with an apparatus where the value of the gas is transmitted wirelessly from the apparatus and an alarm is activated at the apparatus when the value of the gas is above a predetermined value, or an input signal from an input of the apparatus is transmitted wirelessly from the apparatus.
BACKGROUND OF THE INVENTION
or "invention"
relate to exemplary embodiments and not necessarily to every embodiment encompassed by the appended claims.) More specifically, the present invention is related to monitoring of gas in an underground environment or an oil or gas rig with an apparatus where the value of the gas is transmitted wirelessly from the apparatus and an alarm is activated at the apparatus when the value of the gas is above a predetermined value, or an input signal from an input of the apparatus is transmitted wirelessly from the apparatus.
BACKGROUND OF THE INVENTION
[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 invention. The following discussion is intended to provide information to facilitate a better understanding of the present invention. 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.
[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.
75.351.
[0005] 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 Date Recue/Date Received 2023-03-28 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 CommTracTm system.
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 CommTracTm system.
[0006] 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."
[0007] The detail of importance in this section is the mention of "methane". Traditional AMS hardwired systems offer methane monitoring but only in the 0-5% 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 cannot 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.
[0008] 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(i). 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."
[0009] Traditional AMS hardwired systems offer this ability through a hybrid monitor/alarming unit although no wireless options for this requirement exist currently. Mines Date Recue/Date Received 2023-03-28 are often forced to run a separate control network if using a wireless monitoring solution to satisfy the section alarming requirement.
[0010] 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.
[0011] 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.
[0012] 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 carried by a miner and proximity sensors positioned on machinery which, when determining that a proximity device carried 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 carried by a miner, it would be desirable to combine tracking with these functions since they are already present on the miner.

Date Recue/Date Received 2023-03-28
[0013] 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 that ideally work best to transmit voice bidirectionally, in which also can transmit data, and work in combination are desired.

[0067] In regard to figure 5, there is shown a theory of operation of the present invention.
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 CommTracTm 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 CommTracTm 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.

[0068] In regard to figure 3, there is shown a block diagram of the monitor 10. The CommTracTm transceiver 48 is in electrical connection over a UART connection to the antenna 52. The CommTracTm transceiver 48 is also in communication with the battery 14 power supply through which power from the mine power supply is available.

[0069] In the operation of the invention, 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.
[0070] 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 1B 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.

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.
[0071] 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 1A, 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 CommTracTm network 66. The PIC 24, CC 1110, CC 1190 and internal antenna 52 form and define the CIM 72

[0072] 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 signal 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.
[0073] 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 Date Recue/Date Received 2023-03-28 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 CommTracTm network 66.

[0074] 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.
[0075] The wireless communication portion 20 that has been added to the gas detector 70 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 CommTracTm network 66.
[0076] The software in the PIC24 polls the detector's microcontroller, here the Trolex PIC18, on a continuous basis for sensor information. It packages this sensor information and sends it to the CC1110 to be transmitted over the CommTracTm system at configurable intervals.
The software also monitors the information from the PIC18 on the Trolex detector for alarms and if any are generated, a message will be sent to the CC1110 for transmission via the CommTracTm network 66.
The software also monitors the information from the PIC18 on the Trolex detector for alarms and if any are generated, a message will be sent to the CC1110 for transmission via the CommTracTm network 66.
[0077] 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 CommTracTm 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.

[0078] 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 Date Recue/Date Received 2023-03-28 CommTracTm 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.
[0079] 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.
[0080] 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 CommTracTm 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 where 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 CommTracTm network 66 is available.

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 CommTracTm network 66 is available.
[0081] In regard to figure 1B, 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.
[0082] In regard to figures 2A-2E, depending on whether the apparatus is in an input 54 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 Date Recue/Date Received 2023-03-28 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.
[0083] 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.
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.
[0084] 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.
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.
[0085] 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.
[0086] 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 Date Recue/Date Received 2023-03-28 connected to the battery 14, terminal 5 is ground, and terminal 6 is connected to external power for the apparatus to receive external power.
[0087] 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.

[00153] 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 CommTracTm 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 CommTracTm network 66 knows to send or receive the respective information in the appropriate timeframe.
[00154] When the communicator 298 is within a predetermined distance of a CommTracTm 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 CommTracTm 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 CommTracTm node so as to prevent saturating the CommTracTm node transceiver 48.

The transmission power of the transceiver 48 is also reduced by 10 db if the communicator 298 is close to the CommTracTm node so as to prevent saturating the CommTracTm node transceiver 48.
[00155] 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 must 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 Date Recue/Date Received 2023-03-28 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.

When none of the listening intervals in the predetermined listening period do not have this bit, the alert state is considered no longer present.
[00156] 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.
[00157] 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.
[00158] One bit of received information in a listening interval is used to indicate if the CommTracTm 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 CommTracTm node. The apparatus does not need to wait for check in/out acknowledgment.

The apparatus only waits for the network 66 level acknowledgment that indicates the check in/out message made it successfully to the CommTracTm node. The apparatus does not need to wait for check in/out acknowledgment.
[00159] 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 ù needs replacing soon, 2 ù middle life, 3 ù new).
After another pause, a second series of flashes indicate strength of node (1 ùweak, 3 ù strong). The LEDs 306 will flash Date Recue/Date Received 2023-03-28 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.
