Abstract

A wireless adapter module receives data from a monitor device through a wired interface, where the data conforms to a first protocol. The wireless adapter device translates the data to a format compatible with a supervisory control system. The data is transmitted to the supervisory control system through a wireless interface. Various protocols and translations may be used within the wireless adapter module such that a single supervisory control system may communicate with a variety of different vendor'"'"'s monitor devices.

Claims

1. An apparatus comprising:

at least one processor and at least one memory;

a wired interface coupled to the at least one processor; and

a low power wireless network interface coupled to the at least one processor;

wherein the processor is operable to;

receive through the wired interface data conforming to a first automation protocol;

translate the data conforming to the first automation protocol to data conforming to a second automation protocol; and

transmit the data conforming to the second automation protocol through the wireless network interface.

2. The apparatus of claim 1, wherein the processor is further operable to execute instructions operable to:

receive through the wireless interface data conforming to the second automation protocol;

translate the data conforming to the second automation protocol to data conforming to the first automation protocol; and

transmit the data conforming to the first automation protocol through the wired interface.

3. The apparatus of claim 1, wherein the wired interface comprises an RS232C interface.

4. The apparatus of claim 1, wherein the wireless interface includes a physical layer conforming to the IEEE 802.15.4 standard.

5. The apparatus of claim 1, wherein the wireless interface includes interface layers substantially conforming to at least one of a IPV6, 6LowPan stack or a Zigbee interface standard.

6. The apparatus of claim 1, wherein the translation includes one or more of a value translation, a range translation, a format translation, or a message format translation.

7. A method comprising:

receiving through a wired interface data conforming to a first automation protocol;

translating the data conforming to the first automation protocol to data conforming to a second automation protocol; and

transmitting the data conforming to the second automation protocol through a low power wireless network interface.

8. The method of claim 7, further comprising:

receiving through the wireless interface data conforming to the second automation protocol;

translating the data conforming to the second automation protocol to data conforming to the first automation protocol; and

transmitting the data conforming to the first automation protocol through the wired interface.

9. The method of claim 7, wherein translating the data conforming to the first automation protocol includes translating analog data.

10. The method of claim 7, wherein translating the data conforming to the first automation protocol includes translating string data.

11. The method of claim 7, wherein translating the data conforming to the first protocol includes translating enumeration data.

12. The method of claim 7, wherein translating the data conforming to the first protocol includes translating a message format.

13. The method of claim 7, further comprising:

maintaining a data model for use in translating data to and from the first automation protocol and the second automation protocol; and

transmitting metadata describing the data model through the wireless interface.

14. The method of claim 13, wherein the metadata is transmitted in response to a query received through the wireless interface.

15. The method of claim 7, further comprising transmitting data indicating presence of a wireless adapter module through the wireless interface.

16. A system comprising:

a monitor device operable to provide monitor data;

a wireless adapter module coupled to the monitor device through a wired interface and operable to;

receive the monitor data through the wired interface,

translate the monitor data according to a data model to form translated data, and

transmit the translated data through a wireless interface on the wireless adapter module; and

a supervisory control system operable to receive the translated data through a wireless interface on the supervisory control system.

17. The system of claim 16, wherein the supervisory control system is operable to determine the presence of the wireless adapter module.

18. The system of claim 16, wherein the supervisory control module is operable to query the wireless adapter module for the data model and wherein the wireless adapter module is operable to transmit the data model through the wireless interface to the supervisory control module in response to the query.

19. The system of claim 16, further comprising a module programming tool operable to provide an interface for programming the wireless adapter module by transmitting a wireless adapter program to the wireless adapter module.

20. A machine-readable medium having machine-executable instructions for causing one or more processors to perform a method, the method comprising:

receiving through a wired interface data conforming to a first automation protocol;

translating the data conforming to the first automation protocol to data conforming to a second automation protocol; and

transmitting the data conforming to the second automation protocol through a wireless network interface.
