Internet of Things business process chain processing method and system based on transactions

Abstract

The invention provides a transaction-based internet of things business process chain processing method and system, and the method comprises the steps: initiating a transaction when a certain device initiates an event, generating a unique transaction ID through a SnowFlake algorithm, attaching the transaction ID to a message body, and publishing the transaction ID to an MQTT message processor; other equipment monitors through subscription, performs corresponding actions after finding that a new transaction is generated, and reports a response event and a progress to the MQTT message processor; judging whether the transaction is ended or not, and if so, storing the initiating event, each response event and the complete transaction; and a chained traceable business processing mode of state acquisition, progress report, linkage control and traceability between the nodes of the Internet of Things is constructed, so that the use is convenient.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a transaction-based method and system for chain processing of Internet of Things business processes. Background technique [0002] In industry requirements, there are often nodes that involve multiple parties to form a certain business process. Participants can be people or objects (sensors). Some participants need to be linked, such as lighting indicators; some require actions, such as generating switch control Signal; some need to be reported, at what time, what link (node), what event occurs, how to coordinate and process these operations? When the demand of a certain node in the business process changes, how can it be realized through simple dynamic adjustment? These all appear in real industry scenarios, and because these operations are generally hard-coded and highly coupled, the adjustment will affect the whole body, the cycle and cost of implementa...

AI Technical Summary

Problems solved by technology

[0004] The business process is fixed, and the adjustment is inflexible when a new participant joins or exits;

[0005] There is no effective mechanism to judge whether a certain participant responds, and it is not conducive to troubleshooting afterwards;

[0006] The message after the business linkage event is generated cannot be associated or stored;

[0007] Inability to trace back the start, progress, disposition, and end of a business process
