Description

Technical Field

[0001] This invention relates to the field of contactless coupling interface technology, specifically to a control method and system for automatically switching and constraining the interface output behavior in a high-interference environment or under conditions where multiple coupled objects coexist, and for automatically determining the coupling state of a contactless coupling interface. Rather, it is not an improvement to a specific coupling structure or physical transmission mechanism. Background Technology

[0002] Contactless coupling interfaces are widely used in consumer electronics, industrial equipment, and medical devices due to their advantages in waterproofing, dustproofing, abrasion resistance, and safety. Related technologies typically establish energy and / or data signal transmission channels between devices through non-contact methods such as magnetic coupling, capacitive coupling, and inductive coupling.

[0003] In the system-level control technology for contactless coupling interfaces previously proposed by the applicant, a coupling state determination mechanism has been introduced to uniformly constrain and coordinate the output behavior of the interface at the system level, thereby improving the controllability and security of the interface under non-ideal coupling conditions to a certain extent.

[0004] However, in real-world applications, contactless coupling interfaces often operate in more complex environments, such as: the simultaneous presence of multiple potential coupling objects, the presence of metallic foreign objects or electromagnetic interference in the environment, multiple interfaces or multiple device units operating simultaneously in adjacent spaces, or frequent changes in coupling positions accompanied by transient shifts. Under these conditions of high interference or coexistence of multiple objects, the coupling state is prone to confusion, superposition, or misidentification, leading to unpredictable interface output behavior.

[0005] Existing technical solutions are mostly designed for single-target coupled objects or relatively stable coupling conditions. They lack system-level state differentiation and governance mechanisms for high-interference environments or scenarios with multiple potential coupled objects. In particular, they lack control schemes that can automatically identify and determine different coupling states and thereby complete interface working mode switching and output behavior uniform constraints without user intervention.

[0006] In the absence of effective state differentiation and automatic switching mechanisms, when coupling states become confused or change rapidly, interfaces are prone to erroneous energy output, communication anomalies, or system security risks. Therefore, it is necessary to propose a contactless coupling interface control technology for high-interference and multi-object environments to achieve reliable determination, automatic switching, and system-level constraint control of interface output behavior under complex coupling conditions. Summary of the Invention

[0007] Purpose of the invention The purpose of this invention is to provide a contactless coupling interface control method and system for high-interference and multi-object environments. This method can: distinguish, identify, and determine coupling states when multiple potentially coupled objects coexist or when environmental interference is significant; complete state switching without user intervention or external explicit command input; and constrain and selectively control the output behavior through the coupling channel based on the coupling state determination, thereby avoiding system risks caused by miscoupling or state confusion.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: The method is a contactless coupling interface control method for high interference and multi-object environments, applied to a contactless coupling interface system including a first device unit and at least one potential second device unit, wherein the first device unit and the at least one potential second device unit form at least one candidate coupling channel in a non-contact manner.

[0009] The method includes: a multi-source state perception step that collects multi-dimensional state parameters characterizing the current coupling environment, the state parameters including at least one of the following: coupling strength parameter; relative position or spatial distribution parameter; environmental interference characteristic parameter; and the number or characteristic parameter of potential coupled objects. A multi-object coupling state determination step that analyzes the current coupling environment based on the multi-dimensional state parameters, determines whether there are multiple potential coupled objects, miscoupling risks, or interference states, and generates a corresponding interface operating state accordingly. The coupling state serves as the core control variable for the interface operating state, used to uniformly constrain the output behavior of the interface. An automatic interface state switching step that automatically switches between multiple preset interface operating modes according to the interface operating state, the interface operating modes including at least one of the following: target coupling allowed mode; restricted coupling mode; multi-object isolation mode; and output prohibited mode. An output behavior constraint and control step that constrains and selectively controls the output behavior of energy and / or data signals through the coupling channel under the interface operating mode, to avoid unsafe output under non-target coupling or high interference states.

[0010] The system solution is a contactless coupling interface control system for high-interference and multi-object environments, comprising: a state sensing module for collecting multi-dimensional state parameters related to the coupling environment; a state determination module for determining the coupling state of multiple objects; a mode switching module for automatically switching between different interface working modes; and an output control module for constraining and controlling the interface output behavior under different working modes.

[0011] The method is applicable whether or not multiple potentially coupled objects exist. Beneficial effects

[0012] Compared with the prior art, the present invention has at least the following beneficial effects: it can distinguish and determine the coupling state in the presence of multiple objects or in a high-interference environment; it avoids the erroneous output of energy or signals caused by miscoupling or state confusion; it provides a system-level automatic switching mechanism to improve the security and reliability of interface operation; and it does not depend on a specific coupling structure, and has good system versatility and scalability.

[0014] Specific Implementation Examples: In one embodiment, the system operates in an environment where multiple potential receivers coexist. By collecting coupling strength distribution and spatial location characteristics, the system identifies a non-target coupling state and automatically switches to a multi-object isolation mode, limiting energy output and maintaining only necessary state detection signals. In another embodiment, when environmental interference intensity exceeds a preset threshold, the system enters a restricted coupling mode, degrading output behavior to reduce the risk of false triggering.
