Abstract
A peak weight detecting system and method which analyzes signals generated by a load cell indicating a load within a container. The signal indicates a weight which is compared with a stored peak weight. If the new weight exceeds the stored weight, the new weight is verified by comparison to a weight indicated by a second signal from the load cell. If the weights indicated by the first and second signals are within a specified percentage of each other, the weight indicated by the first signal may displace the stored peak weight and may be stored as a new peak weight.
Claims29
A method of detecting a peak weight, the method comprising:
- providing a mobile chassis, a load-carrying container mounted to the chassis, a load cell positioned between the chassis and the container, the load cell configured to generate an electronic signal corresponding to the weight of the container including the load, and a processor configured to receive the signal from the load cell;
- the load cell generating a signal based on the weight of the container;
- the processor receiving the signal from the load cell;
- the processor comparing the signal received against a previously stored signal corresponding to a peak weight of the container;
- the processor stores the signal received from the load cell if the signal indicates a weight of the container greater than the previously stored peak weight signal;
- the processor verifying the newly stored peak weight signal by comparing the newly stored peak weight signal with a second signal from the load cell at predetermined time interval after the newly stored peak weight signal is received;
- the processor displacing the previously stored peak weight signal with the newly stored peak weight signal if the second signal corresponds with a weight that is within a predetermined percentage of the newly stored peak weight signal.

A mobile peak weight detector comprising:
- a chassis;
- a load-carrying container mounted to the chassis;
- a load cell positioned between the chassis and the container, capable of generating signals corresponding to a weight of the container and any loads placed in the container;
- a processor electronically connected to the load cell and including storage for a signal corresponding to a peak weight of the container and any load placed in the container;
- the processor configured to receive signals from the load cell, to compare a first signal corresponding with a peak weight greater than the peak weight corresponding to the stored peak weight signal with a second signal from the load cell at a predetermined time interval after the first signal, and to displace the stored peak weight signal with the first signal if the second signal indicates a weight within predetermined percentage of the peak weight indicated by the first signal.

A method of detecting a peak weight, the method comprising:
- generating a first weight signal corresponding to the weight of a load in a container;
- comparing the first weight signal against a previously stored signal corresponding to a prior peak weight of the load;
- if the first weight signal indicates a weight of the container greater than the weight of the previously stored peak weight signal, storing the first weight signal;
- accepting a second weight signal corresponding to the weight of the load at predetermined time interval after the newly stored peak weight signal is received;
- verifying the newly stored peak weight signal by comparing the newly stored peak weight signal with the second weight signal;
- displacing the previously stored peak weight signal with the newly stored peak weight signal if the second weight signal corresponds with a weight that is within a predetermined range of the newly stored peak weight signal.

A process for detecting a peak weight, the process comprising:
- accepting a first weight signal from a load cell corresponding to the weight of a load in a container;
- accepting a second weight signal from the load cell corresponding to the weight of the load at predetermined time interval after the first weight signal is accepted;
- comparing the first weight signal against the second weight signal, rejecting both signals if the second weight signal is at least a predetermined percentage less than the first weight signal, and restarting the process;
- if the second weight signal is not less than the first weight signal by at least the predetermined percentage, comparing the first weight signal to a previously stored signal corresponding to a prior peak weight of the load;
- and
- if the first weight signal indicates a weight of the container greater than the weight of the previously stored peak weight signal, displacing the previously stored peak weight signal with the newly stored peak weight signal.
