The scope of what we need for the barcode project. I have found a script (Barcode code obtained from 'brechmos' [login to view URL]) that captures and maps the barcodes we scan. The problem and service we need is: -Write a simple admin webpage to map the scanner to the employee --each raspberry pi will have 4 scanners connected to the 4 usb ports --/dev/hidraw0 through to /dev/hidraw4 is how we identify the scanner on the pi and the USB port used within the [login to view URL] script. -At the start of each day the admin will log onto the admin webpage, select the scanner number which we mapped as a variable and can be edited on each [login to view URL] script. (I'm happy to make these changes in the script using vi) --Modify the python script to pipe the data into a MySQL database (employee ID, station, product, time) --The employee will need to scan the station they are working at which sets the station id until the next station is scanned. In the meantime all data is sent to the DB with employee ID, station, product, time A run through of the day: • Employee gets allocated a scanner by admin • Admin logs scanner number to that employee in the webpage • Employee goes to station 1 and scans that station once. o Employee works on 12 products and only scans the 12 products  this is logged as 12 products to station 1 in the DB Next • Employee works on station 5, scans the station o Employee works on 25 products and scans the 25 products as he works on them.  25 products logged in DB under station 5. I envision that we would run a barcode script per scanner on each pi which would need to start on boot, or by default. If you have any questions please let me know. Hopefully I’ve explained this in a way that makes sense.

Hi, I am an electrical engineer and have been working as embedded systems developer for past 4 years. I have developed systems using arduino, STM32, PIC and raspberry pi. I have created a number plate recognition system, driver fatigue detection system and video surveillance system using raspberry pi and pi cam. These projects were very similar to your project. i can complete your project in minimum time and with excellent quality. Looking forward to your response. Thanks

Simple to program, difficult to design. The admin page and the modification of the script from the Raspberry Pi forum will be simple enough. I will also write for you a "watchdog" which monitors that the script is running correctly at all times. -- but the devil is in the details, which I'll be happy to work through with you: * Employee will need to know whether a scan has been successful (positive and negative feedback): misscans are common with barcodes, and is usually handled by the application that will look up the barcode in a dabase. The scanners usually give feedback when a valid barcode has been presented, but if the barcode is damaged, it can still misscan as a different valid barcode. What happens then, is there for example a way to connect a display to the Raspberry Pi which can be seen from all the stations? * What happens if the employee fails to scan the station -- is it still OK to log everything under the previous station? Will there be a need to edit the database manually (perhaps at the end of the day), should this happen (it will sometimes happen, employees are only humans)? * Can we prevent a product being scanned twice by mistake? (Related: what happens if an employee thinks they may have forgot to scan a product or a station? Can they check somehow, perhaps by asking the supervisor, or will they scan again?) Looking forward to working with you. Kind regards, Jan Minar
