Abstract

Field devices, including sensors and final elements, are provided with a speech synthesizer and optionally a speech control chip, to sound audible voice maintenance and fault alarms to alert field personnel and, optionally, a voice message upon manual activation of a pushbutton or other switch directing them how to perform the maintenance task or clear the fault.

Claims

1. An instrumentation and control field device comprising:

a processor;

a memory coupled to the processor;

a speech synthesizer to produce sounds, including allophones;

a speaker;

an amplifier;

at least one pushbutton;

an alarm routine stored in the memory and adapted to be executed by the processor upon a device alert, causing an audible alarm to be sounded by the amplifier and speaker to attract the attention of personnel in the vicinity of the field device;

a status routine stored in the memory and adapted to be executed in the processor upon manual actuation of a switch that causes a text status to be received by the speech synthesizer, the speech synthesizer converting the text status to a spoken status and forwarding the spoken status to be sounded by the amplifier and speaker; and

an optional instructional routine stored in the memory and adapted to be executed in the processor following enunciation of the text status by the speech synthesizer and transmitting a text instruction to the speech synthesizer which converts the text instruction to a spoken instruction and forwards the spoken instruction to be sounded by the amplifier and speaker.

2. The instrumentation and control field device of claim 1 in which the instruction is transmitted upon the manual actuation of a switch.

3. The instrumentation and control field device of claim 1, wherein the audible alarm is a prerecorded sound file.

4. The instrumentation and control field device of claim 2, wherein the audible alarm is selected from a plurality of sounds and the sound is selected based upon the nature of the device alert.

5. The instrumentation and control field device of claim 1, wherein the audible alarm is a text alarm that is transmitted to the speech synthesizer for conversion of the text alarm to a spoken alarm.

6. The instrumentation and control field device of claim 5 which includes a motion sensor responsive to personnel and/or vehicles in a predetermined range of proximity to the device.

7. The instrumentation and control field device of claim 5, further comprising a speech control chip, wherein the text status and text instruction received by the speech synthesizer are first processed by the speech control chip, which instructs the speech synthesizer to sound selected allophones through the amplifier and speaker.

8. The instrumentation and control field device of claim 5, further comprising a speech control chip which first processes the text alarm, text status and text instruction that are transmitted by the speech synthesizer, and which instructs the speech synthesizer to sound selected allophones through the amplifier and speaker.

9. The instrumentation and control field device of claim 1, further comprising a speech control routine stored in the memory and adapted to be executed in the processor, wherein the speech control routine instructs the speech synthesizer to sound selected allophones through the amplifier and speaker.

10. The instrumentation and control field device of claim 5, further comprising a speech control routine stored in the memory and adapted to be executed in the processor, wherein the speech control routine processes the text alarm, text status and text instruction transmitted to the speech synthesizer and instructs the speech synthesizer to sound selected allophones through the amplifier and speaker.
