A unit load combines individual items or items in shipping containers into single "units" that can be moved easily with a pallet jack or forklift truck. A unit load packs tightly into warehouse racks, intermodal containers, trucks, and boxcars, yet can be easily broken apart at a distribution point, usually a distribution center, wholesaler, or retail store.
Inferential load tracking
InactiveUS20120191272A1Improves operational efficiencyEasy to operateAutonomous decision making processDigital data processing detailsUnit loadSystem usage
Methods and apparatus for tracking the location of one or more unit loads in a coordinate space in a facility, comprising an integrated system that identifies a load by communicating with a host computer, determines the position of the load in the coordinate space, and stores the position and load identity in a Load Map. A mobile subsystem on each conveying vehicle identifies the location and orientation of that vehicle using a position / orientation sensor, confirms acquisition of the load, and communicates the information to a fixed-base subsystem when the load is deposited on an automated conveying device. A conveyor controller tracks the load as it is conveyed on the automated conveying device and identifies the load to a subsequent conveying vehicle based upon its position on the conveying device. Loads that are not initially identified are assigned a pseudo-identification for tracking until they can be positively identified.

The invention provides an advanced control method for a coordination system of a boiler and a steam turbine of a thermal power unit, which applies advanced dynamic feedforward technology to the feedforward design of a main control system of the boiler so as to effectively accelerate governing speed of a boiler load command in a load varying process of the unit. In the load varying process of the unit, oscillation tendency of the main control system of the boiler can be inhibited through reducing integral action of a regulator. In the main control system of the steam turbine, a unit load command N0 is subjected to inertia LAG time-delay, and protection design is carried out on main steam pressure. The method ensures that the boiler and the steam turbine can operate under a more coordinated mode and ensures that the thermal power unit has faster ascending and descending speed of load and more stable variation of the main steam pressure, wherein the ascending and descending speed of the load of the unit reaches 3.0 percent Pe / min in actual application, the main steam pressure is stable without overshoot, and the pressure deviation is in an acceptable range.
