Abstract
A process for the acquisition of data of a counting device measuring pulses delivered by a sensor can include reading a first datum value of the counting device. The first datum value corresponds to the pulse emitted by the sensor. The process can also include storing in memory the first datum value as a source value. The process can also include measuring a time-interval between said reading and an incremental change of the first datum value of the counting device to a second datum value. The process can also include obtaining a first adjustment value Vx in response to the measured time interval.
Claims11
A process for the acquisition of data of a counting device measuring pulses delivered by a sensor comprising:
- reading a first datum value of the counting device wherein the first datum value corresponds to a number of pulses emitted by the sensor;
- storing in memory the first datum value as a first source value;
- measuring a first time interval between said reading and a proceeding and upward incremental change of the first datum value of the counting device, said first datum value changing to a second datum value, a third datum value being a preceding and downward incremental change relative to the first datum value;
- and
- obtaining a first adjustment value Vx in response to the measured first time interval.
A data acquisition device for acquisition of data from a counting device operating at a first frequency and measuring pulses delivered by a sensor and comprising:
- a sampling clock outputting pulses according to a second frequency;
- at least one read-input port configured to connect to a data output of the counting device;
- a processing unit configured to sample a datum value through said at least one read-input port and store the datum value as a source value at each pulse of said sampling clock;
- a chronometer measuring a time-interval between a sampling of a first datum value and a change of the first datum to a second datum value at the counting device;
- and
- wherein said processing unit is also configured to calculate an adjustment value at least partially in response to the measured time-interval.
