Abstract

The invention concerns a method for transferring data from a sensor over a computer network, wherein the method comprises the steps of receiving from the sensor a signal representing a physical quantity, encoding the signal, converting the signal into a message, and transmitting the message over the computer network, wherein the conversion of the signal into the message comprises the step of generating the message by combining a first message header with a message body, wherein the first message header comprises the encoded signal and the message body comprises application data. The invention further concerns a device and computer program product therefore.

Claims

1. A method for transferring data from a sensor over a computer network, the method comprising

receiving from the sensor a signal representing a physical quantity, encoding the signal, converting the signal into a message, and transmitting the message over the computer network, wherein, in order to transfer the data along with application data, the conversion of the signal into the message comprises the step of

generating the message by combining a first message header with a message body,

and combining a second message header with the message body wherein the first message header comprises the encoded signal and the message body comprises the application data and the second message header comprises a sensor identification and wherein the first message header after encoding comprises an absolute measure and at least one of the following:

a unit of measurement, a precision, a margin of error, a confidence level, a resolution, and a full scale range.

2. The method according to claim 1, wherein the sensor identification comprises a Universally Unique Identifier.

3. The method according to claim 1, wherein the method further comprises combining a third message header with the message body, the third message header comprising at least one of the following:

a description of the physical quantity, an operational condition of the sensor, and an indication of a data format of the message.

4. The method according to claim 1, wherein the method further comprises combining a fourth message header with the message body, the fourth message header comprising a comment on the message for use by a recipient of the message.

5. The method according to claim 1, wherein the method further comprises encrypting at least one of the message headers.

6. The method according to claim 1, wherein the message is a text message and the method further comprises converting the signal into a textual representation of the physical quantity.

7. A device for transferring data from a sensor over a computer network, the device comprising:

a receiver that is operative to receive, from the sensor, a signal representing a physical quantity,

a converter that is operative to convert the signal into a message, and

a transmitter that is operative to transmit the message over the computer network,

wherein the converter comprises an encoder that is operative to encode the signal into a first message header and

a generator that is operative to generate the message by combining the first message header with a message body, and combining a econd message header with the message body,

wherein the first message header comprises the encoded signal and the message body comprises the application data,

wherein the second message header comprises a sensor identification, and

wherein the first message header after encoding comprises an absolute measure and at least one of the following;

a unit of measurement, a precision, a margin of error, a confidence level, a resolution, and a full scale range.

8. A computer program product comprising a non-transitory computer usable medium including a computer readable program, wherein the computer readable program when executed on a computer causes the computer to

receive from a sensor a signal representing a physical quantity, encode the signal, convert the signal into a message, and transmit the message over a computer network, wherein, to convert the signal into the message, the computer readable program causes the computer to

generate the message by combining a first message header with a message body and by combining a second message header with the message body,

wherein the first message header comprises the encoded signal and the message body comprises the application data,

and the second message header comprising a sensor identification, and

wherein the first message header after encoding comprises an absolute measure and at least one of the following:

a unit of measurement, a precision, a margin of error, a confidence level, a resolution, and a full scale range.
