LONG RANGE DEVICE FAILURE COMMUNICATION SYSTEM

Abstract

A system and method for communicating operation failure of a remote pipeline pneumatic device. A flow detector is used in combination with the pipeline pneumatic device. A controller in combination with the flow detector and a long range communication transmitter communicates an alarm upon detecting a predetermined flow, such as outside an expected amount. The controller can initiate a flow timer upon the actuation of the pneumatic device, and transmit an alarm upon the flow timer exceeding a predetermined value representing the expected amount.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0015] The FIGURE shows a representative implementation of the system according to one embodiment of this invention.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The present invention provides a system and method for monitoring and communicating operation failure for remote natural gas production and/or transport components. The FIGURE shows an exemplary system 20, including a controller 22 in combination with a natural gas line 10 with a pneumatic device 12. The controller 22 includes the necessary control circuitry, and optionally a data acquisition module (DAQ).

[0017] An electric power supply 24, such as a battery, solar panel, thermoelectric generators, or any external power supply, powers the controller 22. In embodiments of the invention, the power supply includes a small power generator (e.g., <1 W), such as a solar panel and/or TEG, with a battery storage. A larger battery alone can be used as well, but the external power generator is desirable to extend battery life.

[0018] The controller 22 includes a communication device, represented by antenna 26, for long range transmission of any detected failures. The communication can be by, for example, Long Range radio (LoRA) and/or a cellular device. A purpose of the device 20 is to determine whether there is a leak, such as pneumatic device 12 leaking, and to communicate to a remote user to inform him/her of the leak/failure of the pneumatic. The communication can cover a range of approximately 10 Km using just a LoRa, or globally using a combination of LoRa and cellular.

[0019] A flow detector, such as a flow switch 30, is placed in the gas flow upstream of the pneumatic device 12. As the device 12 is actuated, the flow switch 30 sends a signal to the controller 22. In embodiments of this invention, when natural gas passes through the flow switch 30 to operate the pneumatic device 12, an electrical circuit closes and is picked up by the controller 22. Once the controller 22 receives this signal, the controller 22 will initiate a timer, e.g., an analog timer. In the event that the timer exceeds a threshold value without the expected gas flow reduction, the controller 22 will send out an alert signal through the LoRA radio, cellular device, or LoRa to cellular device to a designated receiver and inform the user of the timeout of the device and the possible/likely leak or pneumatic failure. The alert signal desirably includes identification information (e.g., the well serial number, GPS coordinates, etc.) for the producer so that they can respond in fixing the leak.

[0020] The invention thus provides a relatively inexpensive (˜$300) monitoring system that communicates a specific location of incidence, allowing for faster response. The apparatus and system of this invention can be implemented as an add-on for existing remote devices, or integrated with pneumatic devices, and/or the respective control systems, at manufacturing. The invention requires installation of switch valve into an existing pipeline, but generally is easily adapted to existing pneumatic pipeline device.

[0021] The invention illustratively disclosed herein suitably may be practiced in the absence of any element, part, step, component, or ingredient which is not specifically disclosed herein.

[0022] While in the foregoing detailed description this invention has been described in relation to certain preferred embodiments thereof, and many details have been set forth for purposes of illustration, it will be apparent to those skilled in the art that the invention is susceptible to additional embodiments and that certain of the details described herein can be varied considerably without departing from the basic principles of the invention.
