A workpiece position tracking and positioning method and positioning system

Abstract

The invention discloses a workpiece position tracking positioning method, comprising steps of defining a plurality of monitoring areas in the workshop and arranging cameras in the monitoring areas, transmitting video images collected by the camera to the computer and performing moving object identification, choosing a scanning area corresponding to the read-write distance of an ultra-high frequency RFID reader-writer in each monitoring area according to the read-write distance of the ultra-high frequency RFID reader-writer, determining the position information and the processing state of the workpiece and uploading the obtained information to an MES production management system. The invention can provide the state information like the reliable workpiece position, processing procedur, etc., uploads the collected data to the workshop MES production management system, replaces the traditional artificial operation, and effectively improves the efficiency of the industrial production management.

Description

technical field [0001] The invention belongs to the field of workpiece positioning methods, and more specifically relates to a workpiece position tracking and positioning method and a positioning system. Background technique [0002] Traditional industrial production management mainly uses manpower to realize production inventory records, production quality inspections, production cost calculations, and production schedule control. With the rapid development of information technology, the production efficiency in many fields has been greatly improved. Due to its status as a basic industry in the national economy, the machinery manufacturing industry has become increasingly important to improve industrial production efficiency and quality. Therefore, further improving the automation of industrial production and realizing intelligent manufacturing is a main direction for the development of machinery manufacturing. [0003] At present, foreign countries have made remarkable a...

Problems solved by technology

In addition, although UHF RFID technology can be used to realize more convenient and quick information scanning and recording, since RFID equipment does not have the function of intelligent switch, there are problems such as being in the working state of signal transmission for a long time, which not only wastes power, but also causes information Redundancy, and the stability decreases after heating, which will reduce the life of the instrument and increase the cost of the factory

At present, a special heat dissipation system has been designed to solve the problem that RFID equipment is always on, but its structure is complex and its applicability is low

However, if the image recognition processing method is used to record and track workpieces, there are problems such as complex algorithms and low reliability.
