Distributed intelligent instrument control system based on Internet of things and method thereof

Abstract

The invention relates to a distributed intelligent instrument control system based on the Internet of Things, including an I / O (input / output) unit, a computing unit, a communication unit and a user terminal device, one end of the I / O (input / output) unit and a field instrument The other end of the I / O (input / output) unit realizes data interaction with the communication unit through the wireless network. The data bus is used between the communication unit and the calculation unit for data communication. Each calculation unit is equipped with a corresponding communication unit. Unit, to complete the transmission and forwarding tasks of signals, parameters, and instructions, the communication unit communicates with the user end equipment through the local area network, the user end equipment includes industrial computers and mobile devices, and the mobile devices include smart phones and Pads; the present invention is the same as the existing Compared with technology, it not only helps to realize intelligent production, improve production efficiency, and improve user experience, but also reduces costs, and helps to realize decentralized control and intelligent transformation of instruments.

Description

[technical field] [0001] The invention relates to the technical field of industrial instrument control, in particular to a distributed intelligent instrument control system based on the Internet of Things and a method thereof. [Background technique] [0002] At present, there are mainly the following schemes for industrial control: [0003] A) Distributed Control System (DCS, DistributedControlSystem) [0004] Introduction: DCS is an instrument control system with decentralized control functions, centralized operation and management, taking into account divide and conquer and comprehensive coordination. It is currently widely used in various industries such as electric power, metallurgy, and petrochemical. [0005] Its structure and principle: DCS adopts hierarchical structure, which is generally divided into control level and management level. The control stage implements decentralized control functions such as signal input, conversion, calculation, and output. It is main...

Problems solved by technology

[0030] Its disadvantages are: cost, security and privacy are the main problems of the Internet of Things; specific to the industrial field, mainly due to the large differences in industries, some fields have invested a lot and achieved remarkable results, but some fields are relatively backward, such as the IoT of smart meters. Networking; users have large investment and need to deploy their own security network; product versatility is poor, and there is no unified technical standard
