# Wire and Cable Quality Traceability System Based on Industrial Internet of Things and Blockchain
## 3 Identity Resolution System and Blockchain Technology Integration Method
### Data Interaction Synchronization for the Integration of Identity Resolution and Blockchain
In order to protect the sustainable development of enterprises and the rights and interests of consumers, according to the quality standards and market access requirements of cable products, it is very necessary to establish a non-conforming product disposal management system and consumer rights protection program in the quality traceability system [35,36]. Reasonable disposal of non-conforming products and active protection of consumer rights and interests can ensure that enterprises respond to quality incidents promptly and effectively, and improve product quality and safety management. #### 5.3.1 Management of Non-Conforming Products

In the production stage, the operation and maintenance personnel through the quality traceability system accurately locate all links of cable production and distribute the corresponding rectification measures. There are three ways to deal with non-conforming

Rework: the quality inspection personnel or quality department will approve the rework of the \"non-conforming product notice\" through the quality traceability system to the corresponding production department for rework so that it can reach the normal standard; Degrade: Change of the quality grade of a non-conforming product to make it conform to the original requirements; Scrap: For products that do not meet quality standards after rework and degrade, scrap them after review. In the market circulation stage, defective products circulated on the market shall be recalled and destroyed promptly before causing losses to consumers. If there has been a loss to the consumer, according to the harm to the consumer, actively give the corresponding compensation processing. #### 5.3.2 Consumer Rights Protection

Wire and cable manufacturers take the interests of consumers as the primary consideration, and the quality traceability system establishes a consumer complaint and claim window, as shown in Figure 19, which is one of the important measures to ensure the rights and interests of consumers. For counterfeit products, assist consumers and hold counterfeit enterprises accountable through relevant market supervision departments. ### System Performance Testing

This paper uses the \"Jmeter2.9\" framework for the identity resolution module to conduct performance tests, setting 100 sets of identification user codes ranging from 0 to 99. Each set has 50 identification codes, using the concurrent gradient method to gradually increase the number of concurrent users, and running each group for 20 to 25 min to collect various data after the test group completes the query and resolution. The gradient curve is obtained. As shown in Figure 20, the actual average response time and Transactions Per Second (TPSs) of the system reach the expected value before the number of concurrent users reaches 70, and part of the TPS reaches more than 20,000 strokes/s. After the number of concurrent users exceeds 70, the actual response time and TPS of the system cannot reach the expected value, but the TPS of the system reaches more than 20,000 pens/s, and the actual response time is within the preset range. The experimental data show that the system has a sensitive response time and high throughput, and meets the expected standards in terms of performance, which in turn realizes such functions as timely response to decision-making commands and powerful data processing, and improves the robust performance of the system to a greater extent.
