Internet of Things System DesignThe design of the Internet of Things system was a comprehensive task that covered many aspects.
In terms of architectural design, a typical Internet of Things system consists of the following key components:
1. ** Perception layer **:
- The sensors and actors were responsible for collecting environmental data (such as temperature, humidity, light, etc.) and performing operations (such as turning the device on/off). The wireless communication module allowed data transmission through wireless protocol such as Wi-Fi, Bluetooth, Zigbee, Lora, etc.
2. ** Network Layer **:
- The gateway acted as the intermediary between the perception layer and the cloud platform, performing the preliminary processing of data and protocol conversion. Communication networks (such as the Internet, mobile networks, or other private networks) provide a data transmission channel from the sensor to the gateway to the cloud platform.
3. ** Platform Level **:
- Cloud platforms provide data storage, computing resources, application services, etc.(e.g., AVS IOT, Azure IOT Hub, Google Cloud IOT, etc.). Edge computing processes data close to the data source, reducing the burden on the cloud platform and increasing response speed.
4. ** application layer **:
- Big data technology and machine learning were used to analyze and process the collected data to extract useful information. According to the analysis results, specific business functions such as intelligent control, prediction maintenance, and user interaction were implemented.
5. ** User interaction layer **:
- The user interface (web pages, mobile applications, desktop software, etc.) provided the user interface, and the API interface allowed third-party developers to develop their own applications or services.
6. ** Security Layer **:
- Identity authentication ensured that legitimate users and devices were connected to the system, data encryption protected data in transmission and storage, and access control restricted users 'access to system resources.
7. ** Management and maintenance layer **:
- The monitoring system monitors the operational status of the Internet of Things system in real time, logs and audit records of system operations and abnormalities for trouble-shooting and compliance audit, updates and upgrades regularly update and upgrade the system to fix loopholes and add new functions.
The design had to follow some principles, such as expansibility (easy to add new equipment and services to adapt to future development), maneuverability (seamless integration of different manufacturers and types of equipment), security (multi-level security measures to protect systems and data), reliability (high reliability, stable operation under various conditions), energy saving and environmental protection (considering equipment energy consumption, reducing energy consumption and environmental impact), etc. At the same time, factors such as technology selection, cost budget, and business needs must be considered to ensure that the system is efficient, reliable, and safe. In addition, there were also related books written based on the professional construction of universities. The content covered the integration method of the Internet of Things system, the design principles and methods of the Internet of Things architecture and its various levels (perception layer, network layer, application layer), and the analysis of typical Internet of Things system application cases. In the actual case of the design of the Internet of Things system, such as the intelligent control system design scheme based on the Internet of Things, the intelligent control box of the Internet of Things, the hardware part would use the STM32 micro-controller as the central processing unit, integrating components such as temperature and humidity sensors, smoke sensors, light sensors, liquid crystal displays, and Wi-Fi modules to realize real-time monitoring and automatic control of home environmental parameters.

Everyday MarriageThe following are some of the web novels related to marriage in the 1980s:
- In "The Beauty of Eighty, She Doesn't Struggle Anymore", the female protagonist had an emotional entanglement with the male protagonist after her rebirth and finally walked towards a happy marriage. The female protagonist had a tragic fate before her death. After her rebirth, she changed her fate through a series of operations. In the process of developing her career, she supported the male protagonist and walked towards a happy family life.
- In "Professor 80's Wife's Daily Life," the female protagonist first fell in love after marriage after she wore a book. She started from the scene of being abducted and capturing the human traffickers. She opened a shop while taking the college entrance examination under the guidance of the male protagonist. Later, she took the road of cultural relic restoration and opened a gold shop with her family. The interaction between the male and female protagonists was interesting.
- In "80: The Beauty Wife of a Long-lived Big Boss", the female protagonist went to find the male protagonist after her rebirth. The two of them went on a blind date, fell in love, developed their careers, went to college, and got married. Although there were many excellent things in the process, the two of them had a good relationship and each had their own careers, achieving redemption and healing.
- In a story about the factory director and his wife, there was a story line between the factory director and Zhang Xiuying. It involved Zhang Xiuying's marriage problems and suspected that her husband had a mistress. The factory director helped her and created some stories in the process.
- In "80's Married to the Factory Manager, An Old Man's Sweet Daily Life", the female protagonist Qiao Man was reborn as a girl in 1982. She had a complicated relationship with the factory manager Lu Zheng (she mistook him for Lu Er). She was originally a cannon fodder female character in the book, and her second sister was the female protagonist.
Everyday in the 1980sPart of the plot of " Everyday Life in the Eighties " involved the villagers teasing Wang Jinxiu about being a widow. Her man was unwilling to go home outside, and the villagers advised her to remarry with her children, but she always giggled. The young and cold Boss Zhong had a wife and children in the countryside. After his career stabilized, he took his wife and children to live in the provincial capital. There were also some puzzling plots about their relationship. At the same time, it was important to note that there were no elements such as rebirth and transmigration in the story. All the natives were set up in an empty setting, and the price level of various places should not be biased.

Sometimes , a few things are unclear, but then overall good. Updates are decent. Almost 1 chap everyday Story is good. There are some inconsistency but can be overlooked. Character design, has yet to be shown. Describes many things of the world background and try to go further.
