Abstract

Methods, systems, and apparatus for determining with dead reckoning the position, relative to an anchor point, of a mobile device. Data indicating an anchor position within a process plant is acquired and an anchor position is determined according to the acquired data. Data indicative of acceleration and orientation of the mobile device are received from circuitry of the mobile device. A position of the mobile device is determined according to the received data and the anchor position.

Claims

1. A method for determining a position of a mobile device within a process control environment, the method including:

acquiring data indicating an anchor position within a process plant;

determining the anchor position according to the acquired data;

receiving, from circuitry of the mobile device, data indicative of acceleration and orientation of the mobile device; and

determining a position of the mobile device according to the received data and the anchor position.

2. A method according to claim 1, wherein acquiring data indicating an anchor position comprises determining a position of the mobile device using a global satellite positioning system.

3. A method according to claim 1, wherein acquiring data indicating an anchor position comprises acquiring an image.

4. A method according to claim 3, wherein acquiring an image comprises acquiring an image of a bar code.

5. A method according to claim 3, wherein acquiring an image comprises acquiring an image of a portion of the process plant and wherein determining from the image a position of the mobile device comprises comparing the image of the portion of the process plant with a database of images associated with locations in the process plant to determine the position of the mobile device.

6. A method according to claim 1, wherein acquiring data indicating an anchor position comprises acquiring data of one or more wireless signals.

7. A method according to claim 6, wherein acquiring data of one or more wireless signals comprises acquiring data of one or more wireless signals conforming to an IEEE 802.11 specification.

8. A method according to claim 6, wherein acquiring data of one or more wireless signals comprises establishing a Bluetooth or near field communication (NFC) communication session.

9. A method according to claim 6, wherein acquiring data of one or more wireless signals comprises acquiring data from an RFID device.

10. A method according to claim 1, wherein acquiring data indicating an anchor position comprises ascertaining a process control device proximate to the mobile device and receiving or retrieving from memory location information associated with the position of the process control device.

11. A method according to claim 1, wherein receiving data indicative of acceleration and orientation of the mobile device comprises receiving data from one or more accelerometers and from one or more gyroscopes.

12. A method according to claim 1, wherein receiving data indicative of acceleration and orientation of the mobile device comprises receiving data from a magnetometer.

13. A method according to claim 1, wherein receiving data indicative of acceleration and orientation of the mobile device comprises receiving data from an inertial measurement unit.

14. A method according to claim 1, wherein receiving data indicative of acceleration and orientation of the mobile device comprises receiving data from an integrated device comprising three accelerometers and three gyroscopes.

15. A method according to claim 1, further comprising launching an application of the mobile device based at least in part on the determined position of the mobile device, wherein the application is operable to modify the operation of the process plant.

16. A mobile device for performing control operations in a process control environment, the mobile device including:
