Description
TITLE
[0001] Working Alone Personnel Monitor FIELD
[0001] Working Alone Personnel Monitor FIELD
[0002] There is described a monitor to be worn by personnel who are working by themselves in environments, where they may encounter protentially lethal gases.
BACKGROUND
BACKGROUND
[0003] There are personnel working in the oil and gas industry, who must travel in their vehicle to remote well sites to check on equipment. At these remote well sites there is sometimes a danger of exposure to potentially lethal gases, such as hydrogen sulphide. There are not always cellular telephones at remote well sites. For this reason, the personnel working alone generally have satellite phones or some other form of communication in their vehicles that will keep them in touch with a dispatcher. When the personnel working alone gets out of the vehicle to check on the wellsite, a gas monitor is worn, so that the presence of gas can be detected. The well site is approached down wind, so that the gas is being blown away from the approaching personnel and so that the person may retreat in the direction they came if the gas monitor detects the presence of gas. If the personnel perceives that there is a potential for danger, a check in time is arranged with the dispatcher, to confirm the worker's safety. What is required is an improved form of working alone personnel monitor.
SUMMARY
SUMMARY
[0004] There is provided a working alone personnel monitor having a body and an attachment for attaching the body to a person who is working alone. A
processor is housed within the body and connected to a timer which is set by the person for a selected time interval. A display displays the expiration of time to the person as determined by the timer. A
gas sensor is carried by the body to sense gas levels. The gas sensor is in communication with the processor. An audible alarm is connected to the processor which receives input from the timer and triggers the audible alarm prior to the expiration of the selected time interval to allow the person working alone an opportunity to reset the timer. The processor receives input from the gas sensor and also triggers the audible alarm (preferably with a different tone) upon sensing that the selected gas exceeds a preset threshold level to make the person aware of excessive concentrations of the selected gas. A communications module is connected to the processor. The processor causes the communications module to send a distress signal at the expiration of the selected time interval.

[0011] Referring to FIG. 5, a communications module 26 is connected to processor 16.
Processor 16 causes communications module 26 to send a distress signal at the expiration of the selected time interval. Processor 16 is programmed with a self test function which causes a test signal to be sent from personnel monitor 10 to a remote monitoring station 30 and a return signal confirmation to be provided and displayed on display 20. This gives the person working alone confirmation before they enter a potentially dangerous environment that communications module 26 has established communication with a remote monitoring station from which assistance may be forthcoming if a problem arises. Referring to FIG
6, remote monitoring station is identified by reference numeral 44.

Referring to FIG
6, remote monitoring station is identified by reference numeral 44.
[0012] Referring to FIG. 6, communications signal of communications module 26 may be relayed through an intermediate vehicle mounted communications station 30.
Communications station 30 includes a communications module 36 capable of receiving local signals from the communications module 26 of working alone monitor 10 and sending and receiving long range communications with the remote monitoring station 44. It also includes a global positioning system module 32 capable of providing global positioning coordinates to remote monitoring station 44 of a vehicle 34 in which it is positioned Operation:

It also includes a global positioning system module 32 capable of providing global positioning coordinates to remote monitoring station 44 of a vehicle 34 in which it is positioned Operation:
[0013] Referring to FIG. 2, working alone personnel monitor 10 is turned on by pushing power button 38. Monitor 10 may then be slipped into a pocket of the operator or clipped onto a belt using attachment 14. Referring to FIG. 6, while it is possible to have direct communication between monitor 10 and remote monitoring station 44, it is envisaged that due to distance communication between monitor 10 and monitoring station 44 will be indirect via communications station 30. Prior to entering into a potentially hazardous environment, the person working alone must test the operation of monitor 10 for both the detection of gas and communications. Referring to FIG. 4, a bump test is performed with a test gas to ensure that monitor 10 is capable of detecting gas. Referring to FIG. 6, once bump test button 48 is pressed, an alert message is sent to remote monitoring station 44 so that remote monitoring station 44 will know that this is a test. Operator then feeds test gas into gas sensors 22, shown in FIG. 5. Monitor 10 detects high gas levels and displays the reading on display 20 and sends an alert to remote monitoring station 44. Remote monitoring station 44 sends an autoreply to monitor 10 to indicate that test was successful. Acknowledge button 46 is pressed to indicate that the operator has confirmed the success of the test and the acknowledge message is returned to remote monitoring station 44.
5 [0014] If communication is lost or not available, monitor 10 will alert the operator with audible alarm 24. Messages are transmitted via satellite 28 through satellite modems.
Referring to FIG. 1, the system will enter alarm mode if panic button 52 is used, if timer 18 is not refreshed or if gas sensors 22 detect a high level of gas.
[0015] Referring to FIG. 2, in the event of an alarm, monitor 10 issues a loud audible alarm 24 and begins to vibrate. Referring to FIG. 6, a message 42 will be seen on display 20 and a message will be sent to communications station 30 and via satellite 28 to remote monitoring station 44. Messages are received by control centre operators and a response according to company emergency response plans may be initialized. Monitor 10 will continue the alert until the alarm condition clears and acknowledge button 46 is pressed.
[0016] In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
[0017] The following claims are to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, and what can be obviously substituted.
The scope of the claims should not be limited by the preferred embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
