A kind of data bus middleware system of internet of things

Abstract

The invention discloses an Internet of Things data bus middleware, which is used to realize Internet of Things data forwarding, task scheduling, and scheduling monitoring. The middleware includes a client and a plurality of server ends, and the client encapsulates communication data according to a communication protocol configuration file After the data packet is generated, according to the service configuration of the client, through the communication function of the client, a call is initiated to all the servers, and the server that responds to the call establishes a two-way micro-channel communication service list according to the communication call of the client, and uses the message analysis of the server The module unpacks the received data packet and obtains the message type in the data packet. At the same time, the server that responds to the call uses the load information collection function in the task scheduling module to obtain the load information of other servers and write it into the task assignment forwarding table , and then, combining the load balancing algorithm and the information in the task distribution forwarding table, determine the server that completes the task, connect and call the corresponding external interface of the server, and realize the forwarding of the task.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, in particular to an Internet of Things data bus middleware. Background technique [0002] The concept of the Internet of Things (IOT) was proposed by the Massachusetts Institute of Technology in 1999. According to the draft overview of the Internet of Things proposed by the International Telecommunication Union (ITU), the Internet of Things is a global infrastructure of the information society, based on existing and ever-changing interoperable information and communication technologies, enabling advanced services and "things" (physical and virtual) interconnections. The Internet of Things provides services for various applications through the development of identification, data collection, processing and communication capabilities, while ensuring the necessary privacy. [0003] Simply put, the Internet of Things is "things connected". However, due to the wide range and variety o...
