During 2£º00-5£º00 on March 30, 2006, Shanghai RFID System Technology Co., Ltd. and Shanghai Beiling Co., Ltd. held ¡°RFID tag RFID Modern Warehouse Management System¡± item identification meeting in Shanghai Beiling Co., Ltd. Relevant commission office of Shanghai municipality, leaders of RFID industry research league and expert Doctor Wang Dong were present in the meeting.
After giving audience to item summarization report and warehouse control system WCS design report, visiting the on-the-spot demonstration of Shanghai Beiling RFID tag warehouse management system, and checking and approving item technical document materials, they reached the consensus that the system has the 2 following characteristics:
1. The item adopts PDA hand-held set on-line movement calculation mode, realizes the seamless butt-joint of warehouse control system (WCS) and the established management system of the enterprise, establishes the example of applied RFID tag in close environment, and has fine modeling effect.
2. This item adopts independently developed RFID tag chip and warehouse control system (WCS) software, innovates the enterprise management process, and obtains fine economic benefit, suitable for promotion and application in society.
The structure and main functions of ¡°RFID tag RFID Modern Warehouse Management System¡±
1.The structure of ¡°RFID tag RFID Modern Warehouse Management System¡± 
2. The main characteristics of ¡°RFID tag RFID Modern Warehouse Management System¡±:
1) Enhancing the visibility of warehouse
As real-time movement calculation technique is added in the warehouse control system (WCS), warehouse workers could use PDA hand-held set so as to know about storage conditions at random and enhance the visibility of warehouse through real-time connection of LAN and WCS system.
2) Improving the accuracy of management
Simply speaking, the ¡°warehouse¡± management in the past is upgraded into the current subdivided ¡°freight space¡± within the warehouse. Under the condition that no warehouse management module (WMS) exists in the management system of the whole factory, only ¡°warehouse¡± management could be realized, which means that we only know whether the goods are in or out of the warehouse or not, but don¡¯t know their precise location (cargo space) or where to obtain the specific good. In the new system, the warehouse is divided into physical freight space and logic cargo space and labeled corresponding RFID tag (named as ¡°cargo space tag¡±); the goods stored in each cargo space will be labeled ¡°good tag¡± containing relevant good information as well as the storage position (cargo space) information.
3) Improving working efficiency
In the process of inventory taking, in the past, the same time was spent to sort and input data after inventory taking. Nowadays, real-time movement calculation technique is adopted which calculates while moving and completes calculation upon completion of movement. The sorting and input of data is totally accomplished automatically by WCS computer system, thus improving the working efficiency.
4) Cutting error rate
In the past, as long as the management machine terminal completed the registration procedures of ¡°warehouse in¡± or ¡°warehouse out¡±, the management system regarded that the good was put in or out of the warehouse, and the conditions of the actual goods depended on human execution conditions. The right or wrong of storage could only be found in inventory checking, and it is accumulative condition.
Now after the completion of the registration procedures of ¡°warehouse in¡± or ¡°warehouse out¡±, hand-held set is used to complete the relevant process prescribed by WCS regulation, until the completion of the reading the tag of the goods. For example, in the process of ¡°warehouse in¡±, only when the good is placed in the prescribed cargo space and corresponding good tag is modified, the procedure of ¡°warehouse in¡± is thus completed. At this time, from the comparison of WCS storage reflection and management system, we could know whether errors exist or not.
In addition, real-time movement calculation technique permits spot check at any time, and you don¡¯t need to wait for the regular inventory checking to ¡°settle the total accounts¡±. All in all, the new system specifies human operation and offers the possibility of checking at any moment, thus decreasing the error rate.
5) Data distribution storage paves the way for logistics management modernization.
6) In the system without RFID tag, all data are stored in computer system; in the new system, the basic information of storage goods is not only stored in the computer system, but also distributed and stored in cargo space tag and good tag. In addition to the above-mentioned advantages, it also tracks materials after goods leaving warehouse management system, namely, the basis of logistics management modernization.
The process of researching and developing RFID tag RFID Modern Warehouse Management System is also our course of groping for RFID tag (RFID) application in modern warehouse management. We should investigate warehouse management market needs and offer whole RFID solution, embracing RFID tag performance and various kinds of packaging, the development of hand-held read-write machine, the functions of warehouse control system, and the seamless butt-joint of new system (WCS) and the original management system as well as the design of cargo space in the warehouse, the design and coding of information storage in good and cargo space tags, the alteration of various working procedures and habits in the warehouse, and others. We try to grope for experience and offer a model for those large-scale enterprises without WMS in management system particularly the uplift and realization of modern warehouse management system for a majority of small and medium sized enterprises.
