Abstract

Measurement sensors are designed to provide metadata to data recording devices in an opportunistic manner to conserve bandwidth and/or power. In one embodiment, the metadata is communicated to the recording device during opportunistic periods, such as, for example, when actual data transmission can be skipped, or when battery level is high, or when there is enough bandwidth, i.e., other sensors are not using the full allocated bandwidth. In one embodiment, a plurality of sensors each only send a portion of their data such that all the portions taken together form the complete metadata. In another embodiment, each sensor only sends an identification of its type and the receiving device “looks up” the full metadata from a database.

Claims

1. A data collection system comprising a plurality of sensors and a data collection device, wherein each sensor comprises:

a program for transmitting data to the data collection device;

wherein the data includes measured data and metadata for assisting the data collection device in utilizing any said delivered measured data; and

a conditional control means for sending the data in separate transmissions including a first transmission and a second transmission, wherein the first transmission contains a portion of the measured data and the second transmission contains a portion of the metadata;

wherein the second transmission occurs in dependence upon fulfillment of a predetermined condition originating at the sensor;

wherein the plurality of the sensors have the metadata common to the plurality of the sensors, wherein each sensor is programmed to send a different portion of the common metadata; and

wherein the data collection device is operable to a) receive the first and the second transmissions from the plurality of the sensors; and

b) combine the portions of the metadata of the second transmissions to obtain the metadata for assisting the data collection device in utilizing all of the delivered measured data obtained by the plurality of the sensors.

2. The data collection system of claim 1 wherein the control means is programmed for sending the portion of said metadata instead of the portion of said measured data.

3. The data collection system of claim 1 wherein the predetermined condition comprises:

the portion of the measured data repeating a previously measured data.

4. The data collection system of claim 1 wherein the predetermined condition is selected from the list of:

available bandwidth, skip data, schedule, high battery, power allocation between metadata and measured data, random.

5. The data collection system of claim 1, wherein all the sensors have substantially identical metadata and the data collection device is common to the plurality of the sensors;

wherein each of the sensors comprises control means for randomly sending portions of said metadata from each sensor to said data collection device.

6. The data collection system of claim 1, wherein the data collection device is further operable to store data from each said sensor without performing analysis on said data until such time as enough metadata is collected from a sensor to utilize at least some of the delivered measured data.

7. The data collection system of claim 1, wherein the data collection device is further operable to combine the portions of the metadata of a particular one of the plurality of the sensors for assisting the data collection device in utilizing the measured data received from the particular sensor.

8. A data collection system comprising:

a plurality of sensors and a data collection device, wherein each sensor comprises;

a program for transmitting data to the data collection device;

wherein the data includes measured data and metadata for assisting the data collection device in utilizing any said delivered measured data; and

a conditional control means for sending the data in separate transmissions including a first transmission and a second transmission, wherein the first transmission contains a portion of the measured data and the second transmission contains a portion of the metadata;

wherein the second transmission occurs in dependence upon fulfillment of a predetermined condition originating at the sensor; and

wherein the data collection device comprises;

a processor for combining the portions of said metadata received by the data collection device; and

a first storage for holding collected measured data from each said sensor until enough metadata has been received by the data collection device for assisting the data collection device in utilizing said measured data from said sensors;

wherein the plurality of the sensors have the metadata common to the plurality of the sensors, wherein each sensor is programmed to send a different portion of the common metadata; and

wherein said processor is operable for combining the portions of the metadata from the plurality of the sensors for assisting the data collection device in utilizing all of the measured data obtained by the plurality of the sensors.

9. The data collection system of claim 8, wherein the predetermined condition is selected from the list of:

available bandwidth, skip data, schedule, high battery, power allocation between metadata and measured data, random.

10. The data collection system of claim 8 further comprising:

a second storage for storing metadata, each said metadata identified by an ID,

wherein the conditional control means of the sensors are suitably programmed to transmit the corresponding IDs to the data collection device; and

wherein said processor is operable for retrieving said metadata from the second storage, according to the corresponding ID received by the data collection device.

11. A data collection system comprising a plurality of sensors and a data collection device, each sensor comprising:

a program for transmitting data to a data collection device;

wherein the data includes measured data and metadata for assisting the data collection device in utilizing any said delivered measured data;

means for measuring data to be delivered to the data collection device;

means for delivering the metadata from said sensor to said data collection device; and

means for sending the data in separate transmissions including a first transmission and a second transmission, wherein the first transmission contains a portion of the measured data, and wherein the second transmission contains a portion of the metadata, wherein the second transmission occurs upon fulfilling a predetermined condition originating at the sensor;

wherein the plurality of sensors all have substantially identical metadata and the data collection device is common to the plurality of the sensors;

wherein each of the sensors comprises means for randomly sending a different portion of said metadata from each sensor to said data collection device.

12. The data collection system of claim 11 wherein the means for sending the data is programmed for sending the portion of said metadata instead of the portion of said measured data.

13. The data collection system of claim 11 wherein the predetermined condition comprises:

the portion of the measured data repeating a previously measured data.

14. The data collection system of claim 11 wherein the predetermined condition is selected from the list of:

available bandwidth, skip data, schedule, high battery, power allocation between metadata and measured data, random.

15. The data collection system of claim 11, wherein said portion of the metadata is an ID pointing to a metadata stored in a database remote from said sensor.

16. A data collection system for collecting data from a plurality of sensors, wherein each sensor comprises:

a program for transmitting data to the data collection device;

wherein the data includes measured data and metadata for assisting the data collection device in utilizing any said delivered measured data; and

a conditional control means for sending the data in separate transmissions including a first transmission and a second transmission, wherein the first transmission contains a portion of the measured data and the second transmission contains a portion of the metadata;
