Internet of things-based intelligent control circuit and controller

Abstract

The invention discloses an Internet of things-based intelligent control circuit and a controller. The intelligent control circuit comprises a PON module, a PHY module, an Ethernet interface circuit, an exchange module, a CPU control module, at least three expansion interface modules, an Internet of things interface module and a power supply module for supplying power to the above mentioned modules, wherein the Internet of things interface module comprises at least three interface circuits; the interface circuits are RS485 and DO interface circuits, DO interface circuits or DI interface circuits; the PHY module is electrically connected with the exchange module through a management data input / output interface in a corresponding cooperation manner; the Ethernet interface circuit is electrically connected with a network port interface of the exchange module in the corresponding cooperation manner. According to the Internet of things-based intelligent control circuit and the controller, by the arrangement of a plurality of slots, insert cards with different interface types and different interface quantities can be plugged into the slots according to an engineering requirement, so that free combination of hardware interfaces is realized.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to an intelligent control circuit and controller based on the Internet of Things. Background technique [0002] With the gradual deepening of industrial integration, IT industry, traditional home appliance industry, communication operators, building intelligence, security alarm products, traditional lighting manufacturers, etc. have been continuously integrated in recent years. Products, security products, lighting fixtures and other front-end products of the Internet of Things are better integrated, which is currently a research hotspot for major manufacturers. [0003] With the further popularization of the network, the requirements for network bandwidth are getting higher and higher, and GPON access technology has emerged as the times require. Compared with traditional Ethernet and EPON, GPON access technology has greater cost and performance advantages. It can be split and co...

AI Technical Summary

Problems solved by technology

This method has obvious disadvantages: 1. The interface combination of the front-end integration is relatively rigid, and different combinations require different types of hardware and different versions of software. The maintainability is poor, the integrated wiring is complicated, and the use and maintenance costs are high.

2. With the further popularization of optical fiber network, the construction cost of this method of connecting to Ethernet is higher than that of using optical fiber access, and the data bandwidth is far below the standard of using GPON
