Modular wireless conveyor interconnection method and system
A modular conveyor system is disclosed in which components of each conveyor module is designed for wireless mesh communication. The communications may be within a module or between modules. Certain of the components may be powered by battery, such that the components may be completely wireless. The network may be entirely self-configuring such that the modules may be assembled and the network established in a straightforward manner.
1. A conveyor module for a modular conveyor system comprising:
a conveyor;
at least one motor coupled to the conveyor and configured to move the conveyor;
at least one motor controller configured to drive the at least one motor; and
a mote configured to enable the least one motor controller to communicate with another device over a wireless mesh network.
2. The conveyor module of claim 1 , further comprising a wireless sensor configured to communicate with another device over the wireless mesh network.
3. The conveyor module of claim 1 , wherein the mote is configured to enable the at least one motor controller to communicate over the wireless mesh network with a handheld control device.
4. The conveyor module of claim 1 , further comprising a pushbutton station configured to communicate with another device over the wireless mesh network.
5. The conveyor module of claim 4 , wherein the pushbutton station comprises a battery and is configured to rely on the battery for power.
6. The conveyor module of claim 1 , wherein the mote is configured to enable the at least one motor controller to communicate over the wireless mesh network with a motor controller of an adjacent conveyor module.
7. The conveyor module of claim 6 , wherein the mote is configured to communicate via an alternate path over the wireless mesh network for communication with the motor controller of the adjacent conveyor module when a direct path to the motor controller of the adjacent conveyor module is obstructed.
8. A method of configuring a modular conveyor system comprising:
sensing actuation of a mote disposed on or associated with a conveyor module, wherein the mote is configured to communicate over a wireless mesh network;
detecting a signal over the wireless mesh network from an upline conveyor module;
receiving a signal from the upline conveyor module announcing the presence of the upline conveyor module;
sending a signal over the wireless mesh network to the upline conveyor module announcing the presence of the conveyor module;
linking the conveyor modules via the wireless mesh network to operate jointly.
9. The method of claim 8 , further comprising detecting a signal over the wireless mesh network from a downline conveyor module, receiving a signal from the downline conveyor module announcing the presence of the downline conveyor module, sending a signal over the wireless mesh network to the downline conveyor module announcing the presence of the conveyor module, and linking the downline conveyor module and the other conveyor modules via the wireless mesh network to operate jointly.
