Here is the English translation of the provided Medical IoT solution description for the four layers (Perception Layer, Transmission Layer, Platform Layer, Application Layer):

Perception Layer:

Used to collect information on patients, medical staff, medical equipment, environment, etc. The collected data from medical IoT terminals is uploaded to the platform layer via wireless IoT communication technologies for unified and centralized processing. It supports both Zhenqu’s proprietary medical IoT terminals and third-party medical IoT terminals.

Transmission Layer:

The transmission layer adopts the construction concept of "convergence, openness, and wireless". It supports the requirements of both comprehensive and phased construction of medical IoT in healthcare institutions. It supports the expansion of wireless IoT technologies and protocols, as well as the free configuration and combination of more protocols. Third-party medical IoT terminals can be supported for access as long as they comply with the standards and specifications of the adopted medical IoT communication technologies.

Platform Layer:

It realizes the unified access and management of all wireless IoT technology capabilities, as well as the unified reception, processing, storage, and distribution of data collected by all IoT terminals. It provides either a single medical IoT basic capability or a combination of multiple medical IoT basic capabilities, achieving an all‑encompassing integration effect. It also provides underlying architectural functions such as permission management and ecosystem access, laying the foundation for enriching the application layer.

Application Layer:

Based on the single or combined medical IoT basic capabilities encapsulated by the platform layer, it builds considerate and meticulous applications tailored to medical scenarios, serving as an assistant for hospital management. It also performs business analysis for intelligent decision-making, becoming the smart brain for hospital operations.
