Abstract
A system and method is configured to take a “snapshot” of data received by a meter or measurement device so that it may be later frozen or duplicated in a manner identical to that of the meter. The system includes recording a continuous stream of raw data into a format suitable for transport to a site better suited for debug and diagnosis, and replaying the data on a replay device such that time, as seen by the system, may be “frozen” at will and any instant of the stream examined.
Claims31
A method for analyzing a measurement, comprising:
- a) programming a measurement device with a predetermined trigger value corresponding to a characteristic of interest detected by said measurement device;
- b) recording a first set of data by said measurement device to a first location;
- c) recording a second set of data by said measurement device to a second location, wherein said second set of data corresponds to a time of occurrence for said trigger value and said first set of data corresponds to a time prior to said occurrence;
- d) playing said first and second sets of data at a time after said occurrence on a simulator of said measurement device, said simulator suitable to operate on said first and second sets of data to produce simulator output data, said output data being smaller than said first and second sets of data.
A method for analyzing a measurement device performance, comprising:
- a) recording an uninterrupted stream of data from said measurement device to a first location, said measurement device having a measurement portion to detect a characteristic of interest and generate said uninterrupted stream of data, said uninterrupted stream of data being of a substantially longer duration that fluctuations in said characteristic of interest;
- b) retrieving said stream of data from said first location;
- and
- c) playing said uninterrupted stream of said data on a replay device, said replay device suitable to process said stream of data in a substantially similar manner as electronics associated with said measurement device.
A method for analyzing measurement data from a measurement device, comprising:
- a) measuring a characteristic-of-interest in a medium by a measurement device to produce measurement data at a measurement data acquisition rate;
- b) producing output data at an output data rate from said measurement device, said output data being based on said measurement data, wherein said output data rate is lower than said measurement data acquisition rate;
- c) recording said measurement data from said measurement device to a first location;
- d) transmitting temporal data corresponding to said measurement data along with said measurement data from said first location to a second location, said second location being outside of said measurement device;
- and
- e) playing said measurement data from said second location on a simulator, said simulator being outside said measurement device, said simulator being programmed to provide a set of output data that substantially reproduces the characteristic-of-interest recorded at said first location.
