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.
Claims10
A process for the acquisition of data of a counting device measuring pulses delivered by a sensor associated with a mobile unit comprising:
- reading a first datum value from a data output of the counting device through a read-input port of a data acquisition device, wherein the first datum value corresponds to a first number of digital pulses emitted by the sensor and corresponds to a sensed position of the mobile unit;
- storing a second datum value with the counting device, wherein the second datum value corresponds to a second number of digital pulses emitted by the sensor, and wherein the second datum value is greater than the first datum value;
- storing a third datum value with the counting device, wherein the third datum value corresponds to a third number of digital pulses emitted by the sensor, and wherein the third datum value is less than the first datum value;
- storing in memory of the data acquisition device the first datum value as a first source value;
- measuring, with a chronometer of the data acquisition device, a first time interval between said reading the first datum value from the data output through the read-input port and said storing the second datum value with the counting device;
- obtaining, with the data acquisition device, a first adjustment value Vx based on the first source value stored in the memory of the data acquisition device adjusted in response to the measured first time interval;
- and
- outputting, from the data acquisition device, the first adjustment value Vx as representative of a position of the mobile unit rather than the first source value.
A data acquisition device for acquisition of data from a counting device operating at a first frequency and measuring pulses delivered by a sensor associated with a mobile unit 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 repeatedly sample a datum value stored by the counting device through said at least one read-input port and store in memory each of the sampled datum value as a source value at each pulse of said sampling clock, wherein each stored source value corresponds to a sensed position of the mobile unit;
- a chronometer measuring a time-interval between a sampling of a first datum value by said processing unit and a change of the first datum value stored by the counting device to a second datum value stored at the counting device;
- and
- wherein said processing unit is also configured to calculate an adjustment value based on the first source value adjusted at least partially in response to the measured time-interval, and said processing unit also configured to output the adjustment value as a position of the mobile unit instead of the stored first source value.
