Abstract

A signal processing method of a baler system includes the steps of receiving a signal, determining a steady state level and relating the steady state level to a characteristic of a forming bale. A signal is received from at least one sensor associated with a bale chamber of the baler system and a steady state level is determined from the signal. The steady state level of the signal is related to a characteristic of the forming bale in the bale chamber.

First claim

1 . A signal processing method for a baling system, the baling system comprising a bale chamber having a floor, a ceiling and two walls each having at least one structural member extending along a bale forming direction, the method comprising the steps of:
receiving a signal from at least one sensor connected to the at least one structural member of the floor, ceiling or wall of the bale chamber of the baler system; determining a steady state level from said signal provided by the at least one sensor connected to the at least one structural member of the floor, ceiling or wall of the bale chamber of the baler system; and relating said steady state level to a characteristic of a forming bale in the bale chamber.

2 . The method of claim 1 , further comprising the steps of:
determining at least one peak value level from said signal; and relating said at least one peak value to a parameter of a plunger in the baler system.

3 . The method of claim 2 , wherein said parameter is a load on said plunger.

4 . The method of claim 3 , wherein said characteristic is a density of the forming bale.

5 . The method of claim 4 , further comprising the step of altering a property of said bale chamber dependent upon at least one of said load on said plunger and said density of the forming bale.

6 . The method of claim 2 , further comprising the step of controlling a density of the forming bale in the bale chamber using at least one of said parameter and said characteristic.

7 . The method of claim 6 , further comprising the step of displaying at least one of said parameter and said characteristic to an operator of the baler system.

8 . The method of claim 6 , wherein said step of controlling the density of the forming bale includes the step of altering a setting of a density ring coupled to said bale chamber dependent upon at least one of said parameter and said characteristic.

9 . The method of claim 2 , wherein said sensor is one of a strain sensor, a deflection sensor and a displacement sensor.

10 . The method of claim 9 , wherein said at least one sensor is an array of sensors.

11 . The method of claim 10 , wherein said array is arranged substantially in a plane.

12 . The method of claim 11 , wherein said signal is a compilation of information from said array of sensors.

13 . The method of claim 12 , wherein said determining at least one peak value from said signal step includes isolating said at least one peak value from said compilation of information.

14 . The method of claim 12 , wherein said determining a steady state level from said signal step includes isolating said steady state level from said compilation of information.

15 . The method of claim 12 , wherein said at least one sensor is an array of sensors, and wherein a the array of sensors are all the same type of sensor.

16 . A signal processing method of a baler system, the method comprising the steps of:
receiving a signal from at least one sensor coupled to a structural member of a bale chamber of the baler system; determining at least one of a steady state level from said signal and a peak value from said signal; and relating either said steady state level to a characteristic of a forming bale in the bale chamber or said peak value to a parameter of a plunger in the baler system.

17 . The method of claim 16 , wherein both said steady state level and said peak value are determined from said signal; and
both said steady state level is related to a characteristic of the forming bale in the bale chamber and said peak value is related to a parameter of a plunger in the baler system.

18 . The method of claim 16 , wherein said parameter is a load on said plunger.

19 . The method of claim 18 , wherein said characteristic is a density of the forming bale.

20 . The method of claim 19 , further comprising the step of altering a property of said bale chamber dependent upon at least one of said load on said plunger and said density of the forming bale.
