Description
Technical field
It the utility model is related to warehousing management equipment technical field, and in particular to a kind of Distributed C AN bus electronic tags
Control system.
Background technology
The appearance of electronic label control system realizes the quick, accurate of Inner Logistics Management, science, convenient four weights
Want target.Simultaneously, WMS can monitor picking process, record picking situation in real time, and can match somebody with somebody with logistics
Send system to realize to be seamlessly connected.
Existing electronic tag controller has three kinds of display formats in the market：
The first is the display for using multidigit nixie tube as controller.Place a controller, control in each goods yard
Device shows the entry/exit quantity of goods in the goods yard using multidigit nixie tube.Because each goods yard is required for a single-chip microcomputer control
Multidigit number tube controller, therefore, when the goods yard quantity of warehousing system is more, cost and fault rate are all higher.It is and more
The information that Digital sum pipe is shown can only be digital quantity, the specifying information of the every kind of goods of display that can not be in detail.
Second is the display for using LCDs as controller.Place a controller, control in each goods yard
Device shows the information such as the name of an article, model, producer, stock and the quantity of the goods yard entry/exit goods using LCDs.Due to every
Individual goods yard is required for a monolithic processor controlled liquid crystal screen controller, therefore, the cost when the goods yard quantity of warehousing system is more
Increase, fault rate increase at a high speed.
The third is the display for using LED light as controller.Place a LED light, control in each goods yard
Device processed lights LED light prompting by control and carries out in/out library cargo operation to the goods yard.One controller controllable hundreds of
To thousands of individual LED lights, therefore, when the goods yard quantity of warehousing system is more, cost and fault rate can keep relatively low.But
It is that LED light is only able to display the position for needing in/out library goods, the name of an article of goods yard entry/exit goods, model, factory can not be shown
The information such as family, stock and quantity, it is additionally, since the method that controller uses centralized Control LED light so that the wiring of system
Measure it is bigger, controller output connection number also compare it is more, reduce the reliability and maintainability of system.
In existing Electron-Label-Aided Picking System, the transmission side data of upper managing computer and electronic tag controller
Formula uses RS485 buses and local network transport two ways.RS485 bus systems can only form primary and secondary structure, communication mode
It can only be carried out in a manner of main website poll, therefore the real-time of system, reliability are poor.Data transfer mode uses local network transport
When, needed when the transmission range of upper managing computer and electronic tag controller is more than 100 meters separately plus repeater so that system into
It is this increase, complicated, be not suitable for using in larger warehouse.
