The application is a kind of intelligent queuing system based on fingerprint identification, belonging to the field of intelligent control technology. For the problem of queuing in railway ticket hall, the system uses STC89C58RD+ single-chip microcomputer as the core, and is matched with FM-180 fingerprint identification module. On the hardware, each module is reasonably connected; on the software, it is designed based on Keil Uvision 4. When taking a number, the system judges the fingerprint situation and enters or prompts the error; when verifying, it prompts according to the fingerprint matching situation. The innovation points include the application innovation of fingerprint identification, avoiding queuing; good human-computer interaction experience through double display screen and voice module; considerate passenger service using infrared sensor. The system can effectively solve the problem of queuing, improve the operation efficiency of ticket hall and passenger satisfaction, and promote the development of railway passenger transport.

The application belongs to the technical field of polymer materials, and discloses a design method of multifunctional hydrogel based on a rare earth-starch system.The hydrogel specifically comprises starch (potato starch / wheat starch / corn starch), acrylamide, polyvinyl alcohol, silver nanowires and europium ions.The hydrogel has a fluorescent and conductive double channel, overcomes the disadvantage of traditional rare earth hydrogel which can only be used as a fluorescent sensor, and provides a stronger network by physical crosslinking of the rare earth-starch, so that the mechanical properties are enhanced; meanwhile, the hydrogel can freely adjust the mechanical properties and the fluorescent intensity by changing the starch content and respond to the external ion environment, and has a very high sensing sensitivity (GF = 9.02) and mechanical properties (strain = 1377%); the dynamic response time can reach 52 ms.The hydrogel sensor has stable performance and is convenient to prepare, widens the application range of the rare earth hydrogel, and has a good development prospect.

This invention provides a method and system for controlling the liquid level in penicillin fermentation based on visual recognition. By introducing visual AI detection technology into the field of penicillin fermentation production and combining it with the characteristics of fermentation liquid level, a complete set of reference standard selection schemes is innovatively constructed. It also proposes key indicators with specificity and innovation, such as "liquid level value", "rate value" and "fuzzy value", to provide quantitative basis for accurate identification and control of penicillin fermentation liquid level. It is linked with the control system to achieve automatic control, realizing accurate, stable and automated closed-loop control of penicillin fermentation liquid level.

This invention patent provides a digital system and its operation method for improving manufacturing quality in C2B manufacturing. It uses a handheld terminal equipped with a quality inspection app to collect data, which is then analyzed and processed in real-time by a server. Quality issues are accurately categorized and alerted to responsible parties, and a closed-loop system for problem containment is completed based on WeChat and a large data dashboard. This system can effectively address quality issues occurring in the workshop, providing real-time and precise intervention and containment, thus significantly improving manufacturing quality.
