# Automated DNA Extraction Monitoring System Based on MTConnect Technology
## 1 Introduction  
At the core of the smart factory, according to the Industry 4.0 trend, is a technology that enables connection between devices [1; 2]. MTConnect standard technology provides simplicity, flexibility, and scalability in integrating various equipment and operating systems and enabling accurate and consistent data collection from any MTConnect-compatible system. It can be used to collect and analyze a large amount of equipment data and monitor them over a network. Using MTConnect technology, it is possible to immediately identify the cause of a problem and respond quickly when a problem occurs. For this purpose, it is necessary to monitor the status of equipment and send status information to the manager in the event of a problem. Since 2007, with the support of the Association for Manufacturing Technology, U.C. Berkeley has been developing a standard protocol and integration method for information exchange between various pieces of production equipment, and as a result, MTConnect was proposed. With this revision and supplementation, MTConnect was established as an open standard based on Transmission Control Protocol/ Internet Protocol (TCP/IP) by the MTConnect Institute [3]. This makes it possible to access the status information and data on different facilities produced by various manufacturers in a standardized form outside the device. The MTConnect standard enables the implementation of a device-independent and highly scalable monitoring system because detailed information on the equipmentrequiring the monitoring system can be obtained in Extensible Markup Language (XML) format. As is well known, robots are embedded with sensors to allow for machine-robot or human-robot collaboration in a safe workspace of smart factories. MTConnect standard technology is applicable in the integration of components of smart factories, such as machines and robots [4; 5; 6; 7; 8; 9]. As a result, more than 500 organizations, including major US and Japanese companies, currently support the standard. In recent years, the healthcare market has demanded rapid diagnosis and treatment according to diagnosis results, and the types of diagnostic devices suitable for meeting these needs are increasing. Point-of-care testing (POCT) devices have attracted attention in recent years because they enable rapid disease diagnosis. In the field of on-site diagnosis, the trend is to expand to other inspection items by developing technology that prevents errors even when generalists rather than specialists are involved. This also applies to situations that require quick inspection results. World-class manufacturers in the field of diagnostic laboratory testing equipment have released many field-testing products to meet these needs. Some manufacturers and startups are investing more in POCT field inspection equipment development than in traditional inspection fields. The next-generation molecular diagnosis field is seeing improvements in the accuracy and efficiency of diagnosis based on digital PCR technology. In the field of field diagnosis equipment, microelectromechanical systems (MEMS)and nanotechnology have been applied to miniaturization, and efforts are being made to effectively apply these technologies to the diagnosis and prevention of diseases through the control, inspection, and data management of diagnosis equipment through convergence with IT technology. This trend may be a result of the various advantages of POCT (e.g., shortening of examination times, patient satisfaction, shortened hospitalization times, improved visibility, reduced expenses, and improved preparedness for emergencies) [10; 11; 12; 13]. POCT equipment has been linked to the telemedicine system, which allows patients to communicate with doctors from their homes. This is a major transformation of the clinical pathological examination system. Confidence in the reliability of POCT equipment is crucial to the equipment's effectiveness in telemedicine systems.
