1, iot application cases are as follows: Equipment monitoring Things like monitoring or adjusting building thermostats can be done remotely, and can even save energy and simplify facility maintenance procedures. Highway construction, mixing station production quality monitoring, remote monitoring of production data, real-time production quality monitoring, this Internet of thingsThe beauty of the application is that it's easy to implement, easy to tease out performance benchmarks, and get the improvements you need.
2. Practical application cases of the Internet of Things include the Chaoyang District Internet of Things Demonstration Park. The park plans to implement futuristic services such as driverless buses and create an intelligent living environment by integrating technologies such as radio frequency identification, sensors, global positioning system and wireless data communication. The park will be divided into commercial, corporate, living and public areas, and aims to provide an application platform for integrating high-tech products.
3, the application of the Internet of things in water conservancy is mainly the hydraulic opening and closing of the gateStatus detection, remote control, fault warning, etc., the use of underwater robots to carry out status monitoring, information return and other underwater states such as DAMS and reservoirs.
4, the main application areas of the Internet of Things The application field of the Internet of Things is extremely wide, the following are some typical application scenarios: logistics and warehousing, health care, intelligent environment, intelligent transportation, intelligent buildings, cultural relic protection, real-time monitoring of monuments, smart home, positioning and navigation, logistics management, video surveillance, digital medical and other industries are involved.
5, Internet of Things smart home application case Cooking rice and coffee for the traditional oven addedWhat are the benefits of WIFI? You can use an app to control the temperature, including preheating and warming, and even cooler, you can download recipes for more targeted cooking.
Find "Radio", "electronic newspaper" and other advertisements, buy a special thermal transfer paper for the production of circuit boards (I from Dongming ElectronicsThe company bought 40 yuan /100 A4 format), prepare an electric iron or a plastic machine, a plastic machine is best; Ferric chloride is essential. 2. PROTEL and others have designed the PCB diagram. 3. Print out the PCB drawing on the thermal transfer paper with a laser printer at 1:1, and set the 180 degree flip before printing. 4.
PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic part, is the support body of electronic components, is the carrier of electrical connection of electronic components. Due to itIt is made of electronic printing, so it is called a "printed" circuit board.
Circuit board is the most important electronic component, is the support body of electronic components, is the electrical connection provider of electronic components, its design is mainly layout design; The use of circuit boards can greatly reduce wiring and assembly errors, improve the level of automation and production labor rate. The inventor of the circuit board was Austrian Paul Eisler, who used the printed circuit board in a radio device in 1936.
Short for, that is, PCB empty board through SMT on the piece, and then through the DIP plug-inThe entire manufacturing process, referred to as PCBA. The difference between PCBA and PCB: From the above introduction, it can be known that PCBA generally refers to a processing process, which can also be understood as a finished circuit board, which can be counted as PCBA after the processes on the PCB board are completed. PCB refers to an empty printed circuit board with no parts on it.
As a bridge that carries electronic components and connects circuits, PCB is an indispensable key basic component in the electronic information industry, because it is made of electronic printing, it is called "printed" circuit board.
PCB is printedPowered launch into space wireless charging plant picture , can operate in orbit wireless charging plant picture , and can travel between the Earth's surface and low Earth orbit, partially reusable spacecraft. It consists of three parts: an orbiter, a solid fuel booster rocket and an external tank.
The Space shuttle is a manned, reusable spacecraft that travels between space and the ground. It can carry spacecraft such as artificial satellites into space like launch vehicles, and it can operate in orbit like manned spacecraftIt can also glide through the atmosphere and land like a glider. The space shuttle provides a good tool for human freedom to enter and exit space, and is an important milestone in the history of space exploration, which was first developed by the United States.
Space shuttle set rocket, satellite and aircraft technical characteristics in one, like a rocket can be vertically launched into space orbit, but also like a satellite in space orbit flight, but also like an aircraft to re-enter the atmosphere glide landing, is a new type of multi-purpose space vehicle.
The space shuttle combines the technical features of a rocket, a satellite and an airplane and can be launched vertically into space orbit like a rocketDao, which can fly in orbit like a satellite and glide into the atmosphere like an airplane, is a new multifunctional space vehicle. Its structure consists of three main parts. ① Orbiter, including three engine rocket, pilot capsule, crew capsule and cargo compartment. ② External storage tank used to provide propulsion.The space shuttle is a combination of an airplane and a rocket. It is launched into space like a rocket and can land at an airport like an airplane. Usually, the space shuttle consists of upper and lower parts Wireless charger factory picture ; The upper part isThe main body of the shuttle, called the orbital stage, is shaped like a jumbo jet.
