Introduction
As Industry 4.0 continues to advance, the manufacturing industry is facing unprecedented changes. Machinery manufacturing, as an important pillar of the industrial system, is actively moving towards a digital, intelligent and automated future. RFID plays a crucial role in this process. By applying RFID labels to equipment, parts, workstations and even employees, machinery manufacturers can realize the process of tracking and data collection, greatly improving production efficiency, reducing error rates and enhancing supply chain transparency. In this article, we will elaborate on how RFID can help the machinery manufacturing industry embrace Industry 4.0 from multiple dimensions.
1. The fundamentals of RFID technology
RFID (Radio Frequency Identification) is an automatic identification technology for non-contact identification via radio waves. It usually consists of three core components:
| Module | Functional Description |
| RFID Label | Attached to the item and contains a chip and antenna for storing and transmitting data |
| RFID Reader | Sends out a wireless signal to activate the label and read the information contained in it |
| Data Management System | Analyzes and processes the read data for use in an enterprise’s ERP or MES system |
According to the different ways of power supply, RFID labels can be divided into three types:
| Type | Power supply required or not | Reading distance | Application examples |
| Passive Labels | No | Short to medium range (a few centimeters to several meters) | Parts identification, WIP tracking |
| Active Labels | Yes | Long range (tens of meters) | High value equipment management, remote asset location |
| Semi-active Labels | Yes (low power consumption) | Medium distance | Asset tracking, semi-automated assembly process management |
The biggest advantage of RFID is the non-contact identification, which can penetrate the occlusion, and read multiple labels at the same time, compared with the bar code is more suitable for high-speed identification and tracking in complex manufacturing environments.
2. Key Application Scenarios for RFID in Machinery Manufacturing
RFID applications in the machinery manufacturing industry have become a key support means to promote Industry 4.0, the following are several typical application scenarios:
