RFID-based maintenance recording system and method for workshop production equipment

Abstract

The invention discloses an RFID-based maintenance recording system and method for workshop production equipment. The system comprises active RFID maintenance record storage tag, an RFID work card, a PDA with an RFID reading-writing device module, wherein the units are fixed on production equipment. The RFID maintenance record storage tag is an active RFID tag with an alarm indication lamp; the RFID work card is a wearable passive RFID tag and is capable of storing identity information of the equipment maintenance staff; and the PDA with an RFID reading-writing device module supporting dual-frequency conversion can read identity information of the work card and read and write maintenance information to the maintenance record storage tag. According to the system and method, the support from the workshop Ethernet network and the background database is not required; the reliability is high; remote communication s realized by using the RFID technology; the system can be used conveniently without short-distance scanning or induction; the maintenance record storage tag has the expiration alarming function; leak detection can be prevented; the maintenance record can be protected based on a PIN code and work card authorization, so that malicious tempering is prevented and the security is high.

Description

technical field [0001] The invention belongs to the field of workshop production equipment maintenance, and more specifically relates to an RFID-based workshop production equipment maintenance record system and method. Background technique [0002] In a manufacturing enterprise, the production equipment owned by the enterprise can be as many as thousands. In order to ensure the safe and reliable operation of all equipment and reduce the failure rate and accident rate, the equipment management department needs to formulate maintenance plans according to the actual working conditions of the production equipment, and regularly Overhaul the equipment. The maintenance record is an important reference material for formulating maintenance plans and implementing specific maintenance measures, and is also an important basis for supervising the work of maintenance personnel. [0003] At present, there are mainly four ways to record the inspection and maintenance of production equipme...

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly four ways to record the inspection and maintenance of production equipment in the workshop of manufacturing enterprises: the first is purely manual paper records and paper archives. Lost, cumbersome to search, and poor sharing; the second is to record on-site paper first, and then manually enter the computer for archiving. This method can permanently save and share the maintenance records, but it requires repeated data entry on the computer, which requires a lot of work and is easy. Error; the third is to store the maintenance records in the local database of the production equipment. This method can realize the sharing of maintenance records when the equipment is networked, but requires the production equipment to have its own operating system and database, and the maintenance records cannot be queried when the equipment fails; The fourth is to manually record and archive online through terminals such as tablets and PDAs. The maintenance personnel scan the barcode on the equipment to obtain the equipment number, and then fill in the maintenance records through the terminal network server, and the maintenance records are stored in the background database.

This method is fast and convenient, but it depends on the network environment of the workshop, it is inconvenient to work when the network signal of the workshop is poor, the reliability is not high, and the barcode on the equipment is easily damaged or covered by dust and oil, making it impossible to obtain the equipment code
