Balancing load among operational system zones
Embodiments are directed to conveyor systems and methods for controlling induction of items within the conveyor systems. In one scenario, a conveyor control system implements a hardware sensor in a conveyor system to generate sensor readings regarding an operational status of a first zone in an operational environment, where the first zone is an area where orders are fulfilled. The conveyor control system receives sensor data from the hardware sensor of the conveyor system. The sensor data includes feedback information for controlling the conveyor system. The conveyor control system then evaluates the received sensor data to determine which conveyable items are currently in the first zone and, based on the evaluation, induces the conveyable items onto the conveyor for the first zone.
1. A method, implemented at a conveyor control system that includes at least one processor, for controlling induction of items within a conveyor system, the method comprising:
implementing a first hardware sensor in a first zone of a conveyor system to generate sensor readings regarding an operational status of at least the first zone in an operational environment, wherein:
the conveyor system carries boxes within and between multiple different zones,
the operational status comprises information relating to the boxes within the first zone, and
at least one other zone selected from the multiple different zones does not comprise hardware sensor;
receiving sensor data from the first hardware sensor of the conveyor system, the sensor data comprising information for controlling the conveyor system;
evaluating the sensor data to determine which conveyable boxes are currently in the first zone;
generate extrapolated data based upon the sensor data, wherein the extrapolated data indicates which boxes are to travel to the at least one other zone; and
based on the evaluation and the extrapolated data, inducing one or more conveyable boxes onto the conveyor system and into the first zone.
2. The method of claim 1 , wherein the operational environment comprises a plurality of zones including the first zone and at least a second zone.
3. The method of claim 2 , wherein each of the second zone has its own hardware sensor configured to generate sensor readings regarding the operational status of its respective zone.
4. The method of claim 2 , wherein the sensor data includes an indication of a number of conveyable items at each zone.
5. The method of claim 1 , further comprising evaluating visual inspection data received from a camera determining which conveyable items are to be induced onto the conveyor for the first zone.
6. The method of claim 1 , further comprising evaluating radio frequency identifier tags when determining which conveyable items are to be induced onto the conveyor for the first zone.
7. The method of claim 1 , further comprising evaluating information from weight sensors when determining which conveyable items are to be induced onto the conveyor for the first zone.
8. The method of claim 1 , further comprising evaluating information from pressure sensors when determining which conveyable items are to be induced onto the conveyor for the first zone.
9. The method of claim 1 , further comprising evaluating information from acoustic sensors when determining which conveyable items are to be induced onto the conveyor for the first zone.
10. The method of claim 1 , wherein the information from the hardware sensor, in combination with information from one or more other hardware sensors in one or more other zones provides a current location of each conveyable item in the conveyor system.
