Abstract
Counting scale with a multilevel Hinkley detector that can recognize the jumps of a very noisy signal s(t) from an average value (standard level) to a new average value. The measured signal s(t) is tested for several hypothetical jump sizes m1 at the same time. A test value h1(t) is established for every jump size using a nonlinear recursive algorithm. By recognizing which test value h1(t) first reaches a threshold value ε, the number of parts that have been added and if necessary removed can be determined.
Claims7
Method for implementing in a computer of a counting scale for recognising jumps in the weights placed on said counting scale,
- characterized in that
- a detector implemented in the computer (Hinkley detector) is present, in which the following computing steps are performed:
- from a number of consecutively measured weight values s(t) a first mean μ0 is formed,
- a second value, the weight of a part m, is entered, which corresponds to the expected weight of a part to be counted,
- the deviation of the new measurement value s(t) from the value μ0 is formed, called innovation e(t),
- a test value h(t) is formed, by after each measurement recursively adding the innovation minus half of the part weight multiplied by half the part weight, and in the event of a negative result setting it to zero,
- it is determined whether h(t) is greater than a pre-specified threshold value ε,
- if h(t)>ε, a jump is detected and this result is processed further.
Counting scale with a computer and a display,
- characterized in that
- the computer contains at least one implemented Hinkley detector.
