In the smart home technology, LonWorks bus takes an important part. Some features of the bus technology also play a key role in the smart home system. Here we describe eight technical features of the LonWorks bus technology in the smart home system.
LonWorks technology is a platform technology for controlling networks. It provides a peer-to-peer control network architecture that provides end-to-end solutions for a wide variety of control network applications.
(1) Has a powerful Neuron chip: The chip is internally equipped with three 8-bit microprocessors, RAM, read-only memory (ROM), and communication and I/O interfaces. The Neuron chip's processor and built-in communication protocol simplifies system programming and only requires application layer programming and parameter configuration by the developer.
(2) Communication media: Communication can be performed using any medium, including twisted pair, power line, optical fiber, coaxial cable, radio wave, infrared, etc., and there can be multiple communication media in the same network.
(3) Interoperability: LonWorks communication protocol LonTalk supports ISO standard seven-layer network protocol, providing a network operating system that is solidified on the Neuron chip, and any manufacturer's products can realize interoperability.
(4) Network structure: It can be master-slave, peer-to-peer or client/server architecture.
(5) Network topology: Star, bus, ring, and freeform.
(6) The network communication adopts the object-oriented design method. The LonWorks network technology is called a network variable (NetworkVariable, NV), which simplifies the design of the network communication as a parameter setting and increases the reliability of communication.
(7) Provide users with a complete set of platforms to develop LonWorks nodes, including single node development tool NodeBuilder, multi-node and system network prototype development tool LonBuilder, node application development language Neuron C and so on.
(8) Provides ready-made network management tools (LonMaker for Windows), network maintenance diagnostic tools (LonManager protocol analyzers), and data exchange interfaces (LNS DDE Server) required to implement network monitoring and human-machine interface applications. Customize these network tools to design a software development platform, LNS (LonWorks Network Service) network operating system.
Solar mobile Power Bank is a new type of power source that converts solar energy into electric energy and stores it in a battery, and at the same time has a mobile nature. The storage battery can be any form of power storage device, which is generally composed of three parts: solar photovoltaic cell, storage battery, and voltage regulating element.
With the energy crisis and the deteriorating environmental problems caused by petrochemical fuels, people are paying more and more attention, and the current digital products are becoming more and more popular. Solar mobile power is developed under this background.
