The following is the design plan descriptions of the contents:
1. According to the amount of data and the complexity of the relationship, choose a block of data management system (such as SQL SERVER or ACCESS), design of database, the relationship between table and table;
2. Write the user program, the realization of function: the use of wireless communication or a serial port communication, electronic tags will scan data into database;
3. Write the user program to realize functions: the management of the electronic label registration function;
4. Write the user program, the realization of data query, management and accounting functions
I think of it as a database management system to do, now is to do a enters sells saves the management system, and function is not perfect, so far can not meet the design requirements,
Here asking our great god can help me do a vb2005 development of serial communication interface, RS232 and can be used to read and write device communications, read the labels of EPC number, then
Can convert EPC Numbers to access database in the commodity information table, the commodity information table with brand name, product number, category number, supplier number, price and other fields,
Hope to be able to make it a window, I added directly into my invoicing system, ah, is too complicated, I am ignorant of the electronic label Iso18000-6 c, to vb.net
Didn't study of serial port communication, with the effort, thank you, the code does not need to be able to run, because my laptop not a serial port, also didn't read and write, read and write only one unit of the instruction for use, you can just do the most simple code we hope you can give me introduce this knowledge, incidentally, can be clear at a glance, with knowledge, thank you, I am QQ270922091, hope glad,

The dynamic library reader didn't offer? Need you to write a serial port communication operating card reader?CodePudding user response:
I have a card reader demo here, but is a c # plait, there should be a dynamic library, you said the key is the teacher of our own software to use wireless communication or a serial port communication, electronic tags will scan data into database, thanks for your reply
