Innovation Solution
A monitoring method and system based on Industrial Internet of Things (IoT) that includes a user platform, service platform, management platform, sensor network platform, and object platform, which interact to detect defective products, compare configuration parameters, and perform necessary corrections to reduce defective product rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If defective products are handled by configuring defective collection areas and manual identification, then defective products can be collected and scrapped, but production costs cannot be effectively controlled and production progress is delayed due to lack of self-inspection and self-correction measures
Solution Approach 1:
The production line device is equipped with self-inspection capabilities through sensors and detection devices that automatically identify defective products during the manufacturing process. The system performs self-correction by automatically adjusting process parameters or stopping the line when defects are detected, eliminating the need for manual identification and collection area configuration.
Solution Approach 2:
The system implements real-time feedback mechanisms where detection devices continuously monitor product quality and transmit information to the control system. Based on this feedback, the system automatically adjusts manufacturing parameters or triggers alerts to maintain product quality and prevent defective products from proceeding to collection areas.
2Ease of operation
If manual staff determination is used to decide whether to correct the production line, then flexibility in decision-making is maintained, but production costs and production progress cannot be effectively controlled
Solution Approach 1:
The system automatically determines whether correction is needed through built-in detection and analysis capabilities. When defective products are detected, the system autonomously evaluates the situation and implements corrective actions or stops production, eliminating the need for manual staff determination while maintaining appropriate flexibility through programmable decision rules.
Solution Approach 2:
Manual staff determination is replaced with an automated control system that uses sensors, processors, and algorithms to make decisions about production line correction. This substitution of mechanical and human decision-making with automated systems enables effective control of production costs and progress while maintaining decision flexibility through configurable parameters.
3Reliability
If comprehensive monitoring and self-correction systems are implemented, then production costs can be controlled and product quality improved, but device complexity increases
Solution Approach 1:
The monitoring system is designed with multi-functional components that perform multiple tasks. For example, detection devices not only identify defective products but also collect data for analysis, trigger alerts, and provide feedback for automatic correction. This universality reduces the number of separate components needed, thereby reducing overall system complexity while maintaining comprehensive monitoring and control capabilities.

AI summary
A monitoring method for a production line based on Industrial Internet of Things is provided. The method includes: sending, by a management platform, defective product testing information in the perception information sent by an object platform to a service platform; comparing, by the service platform, a count of defective products with a first count threshold of defective products preset by each process and generating an instruction for retrieving process information when the count exceeds the first count threshold; receiving, by the management platform, the instruction and sending object platform configuration information and latest-stored operation information to the service platform; performing, by the service platform, a parameter comparison with a same parameter name and generating a parameter configuration instruction; receiving, by the object platform, the instruction and performing configuration, performing the parameter comparison again, and feeding a comparison result back.
