On the precision stage of high-end manufacturing, the magnetic levitation flexible ring-shaped line system is moving at high speed on the complex tracks, carrying semiconductor chips, battery power supplies or precision medical devices with a light and almost frictionless posture. This is a revolution concerning efficiency and flexibility. However, for a long time, the core of this revolution - precise "position sensing" - has been trapped in a seemingly unsolvable physical maze. The accuracy of traditional encoders on a straight line is lost once they encounter the curvature of a circular line; micrometer-level mechanical vibrations and gap changes are sufficient to cause signal distortion and bring the precision down from its pedestal. This is not only a technical bottleneck but also an invisible constraint that limits the entire flexible manufacturing system from advancing to higher complexity and higher reliability.

It is precisely at this critical juncture where challenges and opportunities coexist that Tianxian Digital Intelligence and Magzheng Intelligent have presented their own solutions - the HMS series magnetic levitation flexible ring-shaped line full-closed absolute value magnetic encoder feedback system. It is not merely a product; it is a systematic philosophy that redefines the boundary of circular motion control accuracy. Its core is an intelligent evolution from "passive measurement" to "active perception".

The soul of the system lies in a "smart brain" composed of FPGA hardware acceleration and AI deep training algorithms. Traditional encoders are like a quick-response recorder, faithfully copying position information but powerless against environmental disturbances. The FPGA of HMS endows it with nanosecond-level neural response speed, and the introduction of AI enables it to possess "experience" and "learning" capabilities. Through continuous deep training, the system can dynamically sense and optimize the subtle disturbances in the magnetic field environment, achieving dynamic and imperceptible signal compensation. This means that minor distortions caused by temperature drift, electromagnetic interference, or mechanical stress, before causing errors, have been quietly smoothed out. It is like equipping the encoder with an experienced navigator, not only able to see the way ahead but also able to predict storms and correct the course in advance.

If the intelligent brain is regarded as "God", then the high-precision permanent magnet signal source (NH30 module) and the modular Hall array sensor form its powerful and flexible "form". The NH30 module provides a stable and pure magnetic field source like a reference tuning fork, laying a reliable foundation for all measurements. The innovative modular sensor design - L120mm, L480mm, L960mm, and even custom arc segments R105 - breaks the limit of physical length. They are like Lego blocks that can be infinitely connected, allowing engineers to freely combine any length and shape of "perception neural network" according to the actual layout of the production line. Whether it is a giant circular line of dozens of meters or a complex multi-line shuttle system, HMS can achieve seamless coverage with a unified precision standard. Particularly crucial is that this system achieves an ultra-large installation gap tolerance of 8-10mm. This breakthrough transforms installation from a precise debugging "craftsmanship" into a more easily implementable "standardized project", significantly enhancing the engineering adaptability and long-term operational stability of the system.

At the level of information interaction, the HMS series has constructed an efficient, reliable, and open industrial communication ecosystem. Each L960mm main sensor module is independently integrated with 8 BISS-C high-speed interfaces, like an eight-lane highway, allowing up to eight moving elements on the circular line to report their absolute positions in parallel without interfering with each other in real time. The dual signal synchronous output between adjacent interfaces and the communication maintenance function in idle state ensure the absolute continuity and real-time nature of the data flow, meeting the top-level requirement of precise synchronous control of multiple moving elements. Whether it is the standard RS422, or the optional optical fiber communication (DLT-DLR1160), and the full series of aviation-grade DF51 connectors, all demonstrate its composure and reliability in the harsh industrial environment (such as the clean environment of a semiconductor workshop or the electromagnetic interference of a lithium battery factory).

From laboratory breakthroughs to reliable guardians on the production line, the value of the HMS series ultimately emerges in specific scenarios. In the large-scale production of battery cells, where the cells flow at high speed on a magnetic suspension circular line of up to hundreds of meters, the HMS system ensures that the positioning accuracy of each welding and packaging station reaches the micron level, directly affecting the consistency and safety of the battery. On the fully automated semiconductor production line, where wafer boxes shuttle through the interwoven flexible shuttle lines, any positional deviation could lead to the destruction of a million-dollar wafer, the full closed-loop absolute position information provided by HMS is the coordinate cornerstone ensuring such a "precise dance" to be flawless. In the clean assembly line of medical devices or the fast-paced production line of 3C electronic products, its high reliability, maintenance-free characteristics, greatly enhance the comprehensive utilization rate and production efficiency of the equipment.



Therefore, the significance of the HMS series magnetic levitation flexible ring-shaped line encoder has long gone beyond being merely a "position sensor". It is the "position perception center" of high-end flexible manufacturing systems and an intelligent bridge connecting mechanical motion and digital control. It indicates that Chinese enterprises are transforming from followers to runners-up and even local leaders in the core sensing field of industry. Tianxian Digital Intelligence and Magzhi Intelligent Technology are forging the "replace imports" vow into a key to overcome industry common problems and empower China's intelligent manufacturing to reach a higher level through their solid independent research and development. The precision boundary of circular motion has thus been reshaped.
