Problems solved by technology

The function completed by the traditional M2M terminal is to customize the analysis between the two network segment protocols according to the system integration requirements of each specific project. This kind of M2M terminal based on customized research and development has poor versatility, heavy transplant workload, and repeated development. high cost
Another is to use a custom adapter between the sensing device and the remote transmission device to support the remote communication function of the industrial sensing device, but this adapter can only support some industrial sensing devices, which has poor versatility and will be limited in application promotion. , and increases the cost and development time of the adapter
[0005] On the application side, because the M2M standard protocol has rich functions, many interfaces, and is difficult to understand, the requirements for IoT application developers are very high, and the development workload
At present, when developing application-side programs based on the IoT service platform, IoT application developers not only need to be familiar with the M2M standard protocol, but also need to develop and build WSDL Web Services servers by themselves, and use the JAVASDK of the M2M-A protocol to build applications. In addition, it is necessary to have the ability to operate the WSDL Web Services server; the WSDL Web Services servers developed and built by each IoT application developer are for their own use alone, and cannot be well provided to other developers. It is wasteful and requires repeated investment in construction, which cannot improve the development efficiency of application developers accessing the IoT service platform

Embodiment 1

[0039] This embodiment provides a data transmission method in the Internet of Things system. Before implementing this method, it is considered that many industrial sensing devices often use their proprietary protocols, so the respective protocol formats are different, and for the same measured value Interpretation is also different, so it is necessary for the user to input the basic information of the industrial sensing device (such as the identification of the industrial sensing device) and the protocol configuration information of the private protocol used by the industrial sensing device to the M2M gateway user.

[0040] Among them, the protocol configuration information includes the protocol configuration information of the business flow data and the protocol configuration information of the management flow data; the protocol configuration information for the business flow data includes: the data frame header and its corresponding business packet length, the output format of...

Embodiment 2

[0065] This embodiment provides an M2M gateway, such as Figure 4 As shown, it includes: a receiving module 31 , a searching module 32 and an adapting module 33 .

[0066] The receiving module 31 is used to receive the data sent by the industry sensing device, and the data includes business flow data and / or management flow data; the search module 32 is used to search for the industrial sensor device subordinate according to the identification of the industry sensing device in the data. Protocol configuration information; the adaptation module 33 is used to convert the protocol format and interpretation meaning of the data into the protocol recognized by the IoT platform according to the protocol adaptation information; the sending module is used to send the converted data to the IoT platform.

[0067] Preferably, the M2M gateway may further include: a recording module 34 , a synchronization module 35 and a detection module 36 .

[0068] The recording module 34 is used to reco...

Embodiment 3

[0073] This embodiment provides a middleware platform, which can be used as an M2MAH server middleware platform in Implementation 1, such as Figure 5 As shown, it includes: an analysis module 41 , a determination module 42 , a conversion module 43 and a sending module 44 .

[0074] Parsing module 41, is used for receiving the data from Internet of things platform, and resolves key information from data; Determining module 42, is used for determining the protocol type of key information according to the message body type in the key information, and to the determined protocol type Add corresponding identification; Conversion module 43 is used to convert the key information into protocol format according to the identification and preset state machine is the data recognized by the enterprise application end; sending module 44 is used to send the data identified by the enterprise application end to enterprise applications.

[0075] In addition, it may further include: a verificat...

Abstract

The invention discloses a method for transferring data in internet of things, an internet of things system and a corresponding device, and relates to the technical field of internet of things. The technical problem that in the prior art, development workload is large on a network side because a proprietary protocol of industry sensing equipment is not standard is solved. The system comprises an M2M gateway and a middleware platform. The M2M gateway is used for receiving data sent by the industry sensing equipment, finding slave protocol configuration information of the industry sensing equipment according to identification of the industry sensing equipment in the data, converting protocol formats and interpretation meaning of the data into protocols which can be recognized by the gateway according to the protocol configuration information, and sending the protocols to an internet of things platform. The middleware platform is used for analyzing key information from the data transferred from the internet of things platform, determining the protocol category of the key information according to message body type of the key information, adding corresponding identification to the certain protocol category, and converting the key information into data of which the protocol formats can be recognized by enterprise application terminals according to the identification and a preset state machine.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a data transmission method in the Internet of Things system, the Internet of Things system and corresponding devices. Background technique [0002] The Internet of Things application system based on the Internet of Things service platform needs a remote transmission device (or communication module) to realize the interconnection between the short-range communication network and the long-range communication network. The following will be oriented to the Internet of Things service platform and support remote transmission The terminals are collectively referred to as M2M (machine-to-machine, machine-to-machine) gateways. The M2M gateway is a bridge for the interaction between industrial sensing devices and the Internet of Things service platform. Its role is to translate and convert data using different transmission protocols in two network segments (short-range commu...
