Method for leak source location investigation

A computing device for refocusing a technician equipped with a network of mobile sensors and a handheld device to detect a gaseous emission at an industrial facility, the computing device comprising:

• at least one computer processor:
• an interface to one or more data stores storing recurring measurements obtained by at least three sensors positioned at the industrial facility that has physical components that transport one or more gaseous materials, wherein each of the at least three sensors comprises:
• (i) a battery compartment configured to store electrical charge;
• and (ii) a wireless communication circuitry configured to transmit a measurement;
• and
• a computer-readable memory storing computer-executable instructions that, when executed by the at least one computer processor, cause the computing device to:
• (a) at a time t1, provide an initial potential source location (PSL) in a notification for the technician, who is responsible for operating the handheld device to detect gaseous emissions from a physical component located within the initial PSL at the industrial facility;
• (b) receive through the interface, the recurring measurements obtained between time t1 and a later time t2, by the at least three sensors positioned in a vicinity of the initial PSL, wherein a time interval from the time t1 to the time t2 has a time duration of at least 30 seconds:
• (c) based on the recurring measurements, transform the initial PSL into an updated PSL;
• (d) cause, after time t2, each of the at least three sensors to be physically moved at the industrial facility to positions corresponding to the updated PSL, wherein the updated PSL occupies a smaller area than the initial PSL;
• and
• (e) provide the updated PSL to a user computing device of the technician to refocus the technician to operate after time t2 the handheld device on or near the physical components located within an overlap region of the updated PSL and the initial PSL.

A method comprising:

• (a) at a time t1, sending to a user computing device of a technician, an initial potential source location (PSL) in a notification, wherein the technician is responsible for operating a handheld device to detect gaseous emissions from a physical component located within the initial PSL at an industrial facility that has physical components that transport one or more gaseous materials;
• (b) receiving, at a computing device from a data store, recurring measurements obtained between time t1 and a later time t2, by at least three mobile sensors positioned in a vicinity of the initial PSL at the industrial facility and stored in the data store, wherein a time interval from the time t1 to the time t2 has a time duration of at least thirty seconds;
• (c) based on the recurring measurements, transforming by the computing device, the initial PSL into an updated PSL;
• (d) causing, after time t2, one or more of the at least three mobile sensors to be physically moved at the industrial facility to positions corresponding to the updated PSL, wherein the updated PSL occupies a smaller area than the initial PSL;
• and
• (e) sending to the user computing device by the computing device, the updated PSL to refocus the technician to operate after time t2 the handheld device on or near the physical components located within an overlap region of the updated PSL and the initial PSL.
