[0013] Figure 1 This is a core architecture diagram of the present utility model. DETAILED DESCRIPTION

[0014] The present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0015] The specific implementation process of the utility model is as follows:

[0016] like Figure 1As shown in the figure, a multi-functional integrated peripheral device based on OpenHarmony includes the OpenHarmony LiteOS-M operating system and peripheral function modules. The OpenHarmony LiteOS-M operating system includes an Open APIs application interface layer, an interconnection and interoperability framework layer, a multi-sensor framework layer, and a LiteOS Kernel layer. The peripheral function modules include an ID card reading module, a magnetic stripe card reading and writing module, a fingerprint recognition module, a contactless IC card reading and writing module, and a non-contact IC card reading and writing module. The ID card reading module, the magnetic stripe card reading and writing module, the fingerprint recognition module, the contactless IC card reading and writing module, and the non-contact IC card reading and writing module all perform data and instruction interactions with the OpenHarmony LiteOS-M operating system through the Open APIs application interface layer, the interconnection and interoperability framework layer, and the multi-sensor framework layer.

[0017] Specifically, in the overall architecture of the OpenHarmony system, LiteOS-M, as the core component of the kernel layer, provides underlying support for the peripheral function modules by providing device driver interfaces and a hardware abstraction layer. The LiteOS Kernel layer, as the core of the OpenHarmony LiteOS-M operating system, includes key functions such as process / thread management, memory management, and file system, and provides basic system services and hardware abstraction layer interfaces. Open APIs are application programming interfaces provided by the OpenHarmony system for implementing various application functions. The interconnection and interoperability framework relies on the network management and peripheral management functions provided by the OpenHarmony LiteOS-M operating system to achieve data interaction and communication between devices. The multi-sensor framework is a component used to manage and schedule various sensors in the OpenHarmony system. Through the driver subsystem and hardware abstraction layer interfaces provided by the OpenHarmony LiteOS-M operating system, it realizes access to and control of various sensors, enabling the multi-sensor framework to more flexibly handle different types of sensor devices.

[0018] Each module of the peripheral function module conducts data and instruction interaction through intermediate layers such as the Open APIs application interface layer, the interconnection and interoperability framework layer, and the multi-sensor framework layer. Specifically, the ID card reading module adopts non-contact technology, which can quickly and accurately read ID card information to meet the requirements of identity verification and information security. Through the standard interface provided by the Open APIs application interface layer, it communicates with the OpenHarmony LiteOS-M operating system. With the support of the interconnection and interoperability framework layer, it efficiently transmits and receives ID card data. At the same time, the multi-sensor framework layer provides additional data processing or integration functions. The magnetic stripe card reading and writing module complies with international and national standards such as ISO 7811, meeting the reading and writing requirements of magnetic stripe media such as bank cards; similarly, it interacts with the OpenHarmony LiteOS-M operating system through the Open APIs application interface layer and uses the communication protocol provided by the interconnection and interoperability framework layer to ensure the accurate transmission of data. The fingerprint recognition module adopts advanced biometric fingerprint recognition technology to achieve fast and accurate identity verification, improving the security and convenience of the device; it receives instructions from the OpenHarmony LiteOS-M operating system through the Open APIs application interface layer and returns fingerprint data; the interconnection and interoperability framework layer ensures the fast and secure transmission of this data. Since the fingerprint recognition module is a sensor, the multi-sensor framework layer provides additional data processing or management functions for it. The contact-type IC card reading and writing module supports international and national standards such as ISO / IEC 7816, realizes the secure reading and writing of data, and is applicable to various application scenarios that require contact-type IC cards. The non-contact-type IC card reading and writing module is compatible with international and national standards such as NFC, supports fast wireless data exchange, and is applicable to non-contact-type IC card applications that require speed and convenience. The contact-type IC card reading and writing module and the non-contact-type IC card reading and writing module also communicate with the operating system through the Open APIs application interface layer and use the communication protocol provided by the interconnection and interoperability framework layer to transmit IC card data. The various function modules are connected by hardware, including but not limited to general transmission protocols such as USB interfaces, COM ports, and I2C. The data transmission between modules is scheduled and managed through the LiteOS Kernel layer. Through the collaborative work of each layer of the OpenHarmony LiteOS-M operating system, the efficient, flexible, and secure operation of the peripheral function module is realized. The peripheral function module includes but is not limited to the ID card reading module, magnetic stripe card reading and writing module, fingerprint recognition module, contact-type IC card reading and writing module, non-contact-type IC card reading and writing module described above, and can also be integrated and set according to actual usage requirements.

[0019] In an embodiment of the present utility model, the OpenHarmony LiteOS-M core operating system further includes a low-power framework layer for managing the power consumption of the entire peripheral device. The low-power framework relies on the low-power management function of the LiteOS-M operating system. By optimizing strategies such as task scheduling and power management, it reduces the overall power consumption of the peripheral device, optimizes energy usage, and ensures that the peripheral device can maintain a low-power state during long-term operation.

[0020] In an embodiment of the present utility model, the OpenHarmony LiteOS-M core operating system further includes security management. The security management is responsible for protecting the security and privacy of the system, including but not limited to functions such as identity authentication, data encryption, and access control. Through the algorithm engine, encryption algorithms are used to encrypt data transmission to ensure the security of personal information and transaction data.

[0021] In an embodiment of the present utility model, the OpenHarmony LiteOS-M core operating system is also integrated with a JS engine, providing a complete JavaScript runtime environment, and it is possible to interact with other parts of the system by writing JavaScript code.

[0022] The multi-functional integrated peripheral device of the present invention has characteristics such as high efficiency, security, and strong compatibility, and can be widely applied in fields such as banks, hotels, public transportation, government service windows, security checkpoints, etc., significantly improving the efficiency of identity verification and information processing.

[0023] The above-described embodiments only represent the implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
