Problems solved by technology

Therefore, in the construction activities of the Internet of Things application system, there is a considerable workload in the coordination and development of these interfaces in different parts of the system. However, due to the lack of a unified model or description method, such communication and development are extremely difficult. Inefficient, and the development results are difficult to reuse

Embodiment 1

[0036] The following describes the specific method of using the present invention to implement the interface between different parts of the system under different conditions.

[0037] Interface entity definition between gateway and terminal

[0038] This example mainly illustrates the description method of the interface entity through the process of determining the static attributes.

[0039] 1) Determine the southbound protocol and technical attributes of the callable interface. Possible values ​​include UART (including ZigBee, Modbus, LoRa, etc.), SPI (including various sensors, ZigBee, LoRa, etc.), I2C, TCP / UDP, etc.

[0040] 2) Determine the southbound configuration attribute of the callable interface, which is related to the configuration information specified by the specific protocol and technology, such as the port number of TCP / UDP, the register address of Modbus, the terminal address of LoRa and its gateway, and the network address of ZigBee Wait.

[0041] 3) Determ...

Embodiment 2

[0053] This example mainly illustrates how to use the present invention to standardize the dynamic feature description of the interface entity during actual interface realization.

[0054] RP_F / UART-AGENT is a kind of gateway southbound interface communication entity, which is accessed through the UART of the device (including the UART converted from USB). It can be connected to various modules or devices with asynchronous serial ports, and the external hardware interfaces can be: RS-232, RS-485, SPI, I2C, TTL level UART, etc. It has a proxy processor (STC15 or STC8 series) hardware and its embedded program, its main functions are as follows:

[0055] 1) Solve the plug-and-play problem of Linux or Windows serial port. Through this agent, no matter what kind of interface, which serial port or USB is connected to the gateway system, it can be identified and work normally, avoiding the process of manual configuration.

[0056] 2) Convert the interface level (for example, RS-322...

Abstract

The invention provides an abstract description method suitable for an Internet of Things application system interface and an application thereof, and an interface entity comprises a service interfacebetween an Internet of Things platform and other applications in the Internet of Things, an interface between the platform and a gateway, an interface between the gateway and a sensor / actuator, and aninterface between modules in the platform. An interface entity is abstracted into a callable interface layer, a data processing layer and an interface service layer, and description of the interfaceentity is completed by defining attribute sets on the callable interface layer, the data processing layer and the interface service layer. According to the method, an attribute description method is adopted, and a tree structure is adopted for attribute description, so that the communication design cost in the interface development process can be reduced, the workload of interface development is reduced, and the reliability of interface development is improved.

Description

technical field [0001] The present invention relates to the technical fields of the Internet of Things and M2M, in particular to an abstract description method suitable for an interface of an Internet of Things application system and its application. Background technique [0002] Different from traditional computer application systems, Internet of Things application systems will include various software and hardware or even resources in open network space. These software and hardware modules or resources are complex and use many technologies and standards. They must be integrated into In order to realize the application system function together, the interface between each part must be handled well. Therefore, in the construction activities of the Internet of Things application system, there is a considerable workload in the coordination and development of these interfaces in different parts of the system. However, due to the lack of a unified model or description method, suc...
