Data bus middleware of Internet of things

Abstract

The invention discloses a data bus middleware of the Internet of things, which is used for realizing the data transmission, task scheduling and scheduling inspection. The data bus middleware of the Internet of things comprises a client-side and a plurality of server-sides, wherein after the communication data is encapsulated into a data packet by the client-side according to a configuration file of a communication protocol, according to the service configuration of the client-side and through the communication function of the client-side, all server-sides are called; the service terminal which responds to the calling establishes a bidirectional micro-channel communication service list according to the communication calling of the client side; a message analysis module of the server sides is used for unpacking the received data packet to get the message type in the data packet; in addition, the server sides that respond to the calling utilize the loading information collecting function of the task scheduling module to get the loading information of other server-sides and write the loading information of other server-sides in a task distributing forwarding table; then the server side that completes the task is determined by combining the load balancing algorithm with the task distributing forwarding table; and an external interface of the server side corresponding to the calling is connected to realize task forwarding.

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...
