Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in detail.
Elaborate a lot of detail in the following description so that fully understanding the present invention.But the present invention can implement to be much different from alternate manner described here, those skilled in the art can do similar popularization in the case of intension of the present invention, and therefore the present invention is not limited by following public being embodied as.
The present invention based on RFID (RadioFrequencyIdentification, RF identification) the car load material object traceability system of technology, the object reviewed is the vehicle being pasted with RFID label tag, before the best opportunity of labeling is vehicle release, the identification number of each RFID label tag is unique, thus RFID label tag can uniquely represent its vehicle attached, it will be understood that the number of vehicle is without limitation.Car load material object refers to that automobile is in kind own in order to be different from automobile account and review, and label is to be pasted on car object itself, non-dismountable, the most transferable, has anti-fake effect, represents a code in article itself rather than software completely.
Traditional car load material object traceability system is often difficult to carry out and persistently use, one of reason is not find suitable link to carry out labeling, the typically labeling when vehicle outbound link or arrival 4S shop, thus substantial amounts of operating pressure is transferred to the busiest and that Comparision is unordered logistics department, and be labeling shipment the most immediately, not verifying the quality of label and also do not have remedial measure, often there is any discrepancy with reality so to may result in the result made an inventory in 4S shop.
The present invention solves the many difficulties of production line labeling, labeling operation has been changed into the windscreen preprocessing link of production line, and binding operation has been placed on report work link.In windscreen preprocessing link, operator can lie on a support one piece of windshield, after mopping and cleaning, from RFID label tag box, take out a piece of RFID label tag, be attached to the windscreen upper left corner gently, then smooth jail is touched, and be now arranged on the RFID card reader on windscreen underlying holder and just read the label that this piece posts, it is effective that operator hear that dichloro-diphenyl-dichlorothane prompt tone represents label, without sound, then represent tag defeat, can shovel patch one again immediately.In report work link, operate the vehicle frame VIN number by handheld terminal scanning vehicle, then the RFID label tag TID (identification number) in the windscreen upper left corner is scanned, data are automatically uploaded to report in construction equipment by wifi (wireless network) and carry out interface display, can be completed the report work of vehicle by tag reader identification.
On the one hand several operation is shared in work, product line will not be caused to block up；On the other hand labeling link is labelled and can be played effective role of inspection by report work link, labels and wrong, invalid can never flow to next one link；Another aspect report work link acquires vehicle FRID label information, just represents a qualified automobile production complete, car load review the most from here on, it is ensured that review the integrity of chain.
It is attached to the windshield upper left corner by unified for RFID label tag, move on to produce on the left of line with the workbench of Times construction equipment is also unified, all operate at left front door with Che Ka and RFID scanning motion, greatly reduce invalid action, invalid walk about, improve work efficiency, the either simplex sequence operating time was reduced to 83 seconds by original 112 seconds.
When report work station has little time operation or operator leave the post temporarily, available handheld terminal is done the benefit binding action of off line and is promptly reported work action before the vehicle pass by, to make up delaying work above, it is to avoid mistake flows to next operation, it is achieved promptly report work.
The present invention can use wifi wireless communication mode, during efficient real, without manual action, arrange on the server and wifi can be transmitted the pallet software that data transfer the data of Simulation of keyboard input to, can be realized by pallet software, the data of handheld terminal collection are directly presented in the MES system of report work point, and just as manually with input through keyboard vehicle frame VIN code, and MES system is not required to do any change.
Referring to Fig. 1, the car load material object traceability system of the present embodiment includes: the first handheld terminal 1, MES (manufacturingexecutionsystem, manufacturing execution system) system 2, at least one second handheld terminal 3, finance take inventory system 5 and data center 4.First handheld terminal 1 and the second handheld terminal 3 are can be for identifying RFID label tag, having the input port for inputting information of vehicles and existing handheld terminal can be used to realize by the terminal of transmitted data on network, do not repeated them here.
