Digitising By Road Dispatch Operations by QR Code Verification in Mines

Abstract: In an iron ore mine in South India, the mine team recently tried to solve the problem of trip sheet verification using QR code scanning. In a byroad truck dispatch, every trip dispatched carries a printed copy of the DMG sheet. The concern here is printing the same trip sheet as generated against the number as registered on the DMG site; avoiding double generation of the same trip on two sheets (which happens due to a slight delay between the generation of the sheet and its reflection on the website); ensuring the generation of only those permits which have got a clearance for the given day. The solution to this could be preventive or corrective. Due to the nature of the DMG website, a foolproof preventive measure has yet to be found. But a QR code-based corrective measure has been developed. The team is extracting the following information from the QR code: a. Sheet number against which the trip is generated b. Permit number c. Vehicle number. This data is then automatically matched with: a. Physical trip sheet number, as in the barcode b. Master data containing allowed permits with their validity date c. A formula to avoid double trips of the same vehicle at a given interval. Moreover, a separate sheet linked to the above two keeps track of sheets used and barcode numbers missed, if any. The next steps could be the use of a Raspberry Pi and OLED for implementation at all exit gates and a dashboard for central monitoring. And the ultimate solution would be a preventive measure.
