Method, device and system for processing sensor protocol information

Abstract

The invention discloses a method, a device and a system for processing sensor protocol information. The method comprises the following steps that: a platform of Internet of things receives initial data from a terminal of Internet of things, and determines a protocol type of a sensor performing information interaction with the terminal of Internet of things and a protocol resolving procedure corresponding to the protocol type, wherein the initial data is metadata encapsulated by a protocol of the sensor; the platform of Internet of things extracts the metadata from the initial data by using the protocol resolving procedure, and sends the extracted metadata to a corresponding application system; or the platform of Internet of things sends the protocol resolving procedure to the terminal of Internet of things, receives the metadata extracted from the initial data by the terminal of Internet of things according to the protocol resolving procedure, and sends the metadata to the corresponding application system. According to the invention, the application system can support various sensor protocols.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for processing sensor protocol information. Background technique [0002] A sensor is a physical device that can detect and collect external signals, physical conditions (such as light, heat, humidity) or chemical composition (such as smoke), and transmit the collected information, and is widely used in IoT systems. [0003] In the existing technology, the sensor usually uses a proprietary sensor protocol to encapsulate the collected metadata, and sends the encapsulated initial data to the IoT terminal; the IoT terminal transparently transmits the received initial data to the corresponding application system (such as home security, environmental protection, agricultural irrigation and networked cars, etc.). The application system performs protocol adaptation on the received initial data, parses out the specific protocol type, and uses the corre...

AI Technical Summary

Problems solved by technology

[0006] When the application system does not store the protocol analysis program corresponding to the received initial data, the application system cannot extract metadata from the initial data

In order to support multiple sensor types, the application system usually integrates multiple sensor protocol analysis programs, which increases the complexity and maintainability of application system development; because different application systems need to integrate their own supported sensor protocol analysis programs, multiple application systems Many repeated protocol analysis programs are often stored between them, resulting in the redundancy of sensor protocol analysis programs

In addition, the application system has a strong dependence on the sensor protocol. When the IoT terminal needs to add a new sensor type, the application system needs to modify and add a new protocol analysis program; in addition, in addition to the data transmission between the sensor and the IoT terminal In addition, it is also necessary to interact with the IoT terminal for control information. The control information can be the handshake information for establishing a connection, and it is the private format information encapsulated according to the private protocol of the sensor. Therefore, the IoT terminal cannot pre-judge its protocol type. When the IoT terminal does not support its protocol type, the control information from the sensor cannot be processed
