The Internet of Things (IoT) refers to the deployment of various information sensing devices with certain sensing, computing, and execution capabilities in the physical world. The information is transmitted, coordinated, and processed through network facilities to achieve wide-area. Or a wider range of information exchange and exchange between people and things, things and things. Its purpose is to realize the connection between objects and objects, objects and people, all items and networks, and to facilitate identification, management and control. Internet of Things technology has broad application prospects in the fields of national defense, industry, urban management, public security, telemedicine, intelligent transportation, smart home , smart grid, environmental monitoring and green agriculture. Under the current situation of vigorously promoting energy conservation and emission reduction and delaying global warming, the Internet of Things provides the basis and key technologies for the integration of “management and control operations†in a harmonious society that achieves “high efficiency, energy conservation, safety and environmental protectionâ€. The technology is believed to set off the third wave of the information revolution. In the architecture of the Internet of Things, this paper attempts to discuss the related concepts with the indoor environment as the scene, gives the application model, analyzes the practical key technologies such as data perception, processing and comfort monitoring, and conducts experiments and makes Exploratory conclusions. 1 Related research The concept of the Internet of Things should first be proposed by Professor ASHTON K, director of the Auto-ID Center for RFID research at the Massachusetts Institute of Technology in 1999. Various government departments have conducted extensive research on IoT-related technologies and industries and formulated a series of development plans. In July 2011, the Ministry of Science and Technology of China issued the “National “Twelfth Five-Year Plan†for Science and Technology Developmentâ€, integrating the Internet of Things as a new generation of information technology into a strategic emerging industry with key developments in the country, and including the Internet of Things. The new generation of broadband mobile wireless communication network is among the major national science and technology projects. However, the existing research results are mainly concentrated in the fields of industry, transportation, security, etc. There are few studies on indoor Internet of Things for smart home and factory environment monitoring. In recent years, the emergence of cloud computing technology, allowing users to access various computing resources, such as computing power, storage capacity, applications, services, etc., through the Internet, provides support for the development of the Internet of Things. At the same time, people are increasingly coming to the home indoor environment. The more attention, the quality of indoor environment directly affects the quality of human life, and even the survival of human beings. References discuss the relationship between indoor environmental parameters (temperature, relative humidity, acoustic environment, and light environment) and indoor environmental comfort. 2 system model design In the initial stage of the development of the Internet of Things, its standard architecture is generally three layers: the perception layer, the network layer and the application layer, but the data generated, analyzed, processed and managed by the Internet of Things is massive, and the original data must have various actualities. Meaning, need to be supported by a huge amount of scalable computing resources. Cloud computing can provide flexible, infinitely scalable, and inexpensive computing and storage services to meet the needs of the Internet of Things. Therefore, this paper adds cloud computing to the IoT architecture to provide powerful computing power and computing intelligence services for IoT business needs. , constitute an improved online monitoring model of the home indoor environment including the sensing layer, the network layer, the cloud service layer and the application layer 4, as shown in FIG. 1 . The sensing layer includes a data acquisition terminal device such as a sensor and a sensor network in front of the data input gateway. In the model, this layer is a wireless sensor network based on the ZigBee protocol; the network layer is mainly responsible for network access, network transmission, and corresponding management and control. The layer consists of the Internet, the remote intelligent monitoring platform and the network access program of the server cluster; the cloud service layer is mainly responsible for storing, mining, and analyzing the existing data, providing timely, scalable, and intelligent services for the application layer to ensure the application layer. Reliability, security, and scalability, can provide storage, query, analysis, mining, understanding and basic services based on sensing data decision and behavior according to needs; application layer solves information processing and human-computer interaction on system requirements The problem is to use the home indoor environment as the application scenario of the Web application service system to monitor the indoor environment and terminal equipment, and to adjust, analyze and predict the environmental status.
DADNCELL 1.5V AAA alkaline batteries are more suitable for
long-lasting continuous discharge and high-performance power consumption
equipment because of their unique internal component structure, coupled with
better battery materials, improved power capacity and electrical performance,
and the same model of DADNCELL 1.5V AAA alkaline cell capacity and discharge time, Alkaline
battery capacity and discharge time are 4-7 times that of ordinary batteries,
and the gap in power discharge performance at high and low temperature is even
wider.
At present, all types of cells developed by DADNCELL Labs do not involve any
heavy metals in production, are green and can be disposed of with domestic
waste.
DADNCELL 1.5V AAA battery advocates a more comfortable and smooth
power supply experience for household appliances. Alkaline zinc-manganese dry
battery series is suitable for various common household electronic equipment
instruments such as smart door locks, infrared thermometers, cameras, flash
lights, razors, electric toys, instruments, high-power remote controls,
Bluetooth wireless mouse keyboards, etc.
