Abstract

A base station for gathering data from localized sensors is described. An example apparatus includes a sensor to be operatively coupled to field equipment, the sensor having a radio frequency transmitter to send a signal to a base station, the base station having a radio frequency interface to receive the signal from the sensor and a first controller to collect data from the signal and store the data in a memory. The apparatus further includes a second controller operatively coupled to the first controller to relay the data to an asset management system and a local control panel operatively coupled to the base station to send additional data to the base station, wherein the first controller stores the additional data in the memory.

Claims

1. An apparatus comprising:

a sensor to be operatively coupled to field equipment, the sensor having a radio frequency transmitter to send a signal to a base station, the base station having a housing comprising;

a first radio frequency interface to receive the signal from the sensor;

a first controller to collect data from the signal and store the data in a memory; and

a second radio frequency interface to communicate the data to a portable device;

a second controller operatively coupled to the first controller to relay the data to an asset management system; and

a local control panel operatively coupled to the base station to send additional data to the base station, wherein the first controller stores the additional data in the memory.

2. The apparatus as defined in claim 1, wherein the second controller is operatively coupled to a field device of a process control system.

3. The apparatus as defined in claim 1, wherein the base station further comprises a Bluetooth interface to send alerts or alarms to the asset management system.

4. The apparatus as defined in claim 1, wherein the base station further comprises a power management module to harvest energy from a nearby radio frequency emitting device to communicate with the radio frequency emitting device.

5. The apparatus as defined in claim 1, wherein the signal transmitted by the sensor comprises a write signal including the data and a write location to the base station.

6. The apparatus as defined in claim 1, wherein the sensor is paired with the base station using near field communication to obtain a device identification.

7. The apparatus as defined in claim 1, wherein the local control panel further comprises an input operative to perform valve testing.

8. The apparatus as defined in claim 1, wherein the base station further includes a bus, the first radio frequency interface, the second radio interface, and the controller coupled to the bus of the base station.

9. The apparatus as defined in claim 8, wherein the memory of the base station is coupled to the first radio frequency interface, the second radio interface, and the controller via the bus.

10. The apparatus as defined in claim 8, wherein the local control panel is coupled to the base station via a wired connection to the bus of the base station.

11. A method comprising:

collecting, via a sensor, data relating to first field equipment;

transmitting the data to a base station using an ultra-high frequency interface of the base station for storage in a memory of the base station;

accessing, via a mobile device, the data in the memory of the base station using a high frequency interface of the base station or a local control panel operatively coupled to the base station via a bus, the local control panel located remotely from the base station; and

relaying the data to an asset management system via a controller of the base station.

12. The method as defined in claim 11 further comprising pairing the sensor with the base station by placing the sensor proximate to the base station and using near field communication to obtain a device identification.

13. The method as defined in claim 11 further comprising processing the data to determine a status of a field device.

14. The method as defined in claim 13 further comprising sending an alert or an alarm to a workstation, via a Bluetooth interface of the base station, based on the determined status of the field device.

15. The method as defined in claim 11, wherein relaying the data further comprises sending the data from the controller to a positioner using a UART communication protocol.

16. The method as defined in claim 11 further comprising transmitting data to the memory of the base station from the local control panel.

17. The method as defined in claim 16, further including performing valve stroke testing via the local control panel, the data transmitted from the local control panel to the memory of the base station related to the valve stroke testing.

18. An apparatus comprising:
