What are the remote control socket brands, the top ten socket brands recommended Siemens company was founded in 1847, the company's headquarters is located in Germany, is the world's famous electrical field enterprises. It is now listed on the Frankfurt and New York stock exchanges. During 2013, its total revenue reached 6.4 billion euros, and it has nearly 20,000 employees in China, so it is a household name switch remote socket brand.
In the medical field, wireless products also play an important role. For example, wireless stethoscope, wireless monitor, etc.
Roaming treasure is a portable wireless router that can make mobile phones and other mobile terminals surf the Internet in foreign countries through wifi connection, with small portability. Developed by Shenzhen skyroam Technology Co., LTD. (founded in Silicon Valley, USA). Skyroam's patented VSIM-based global roaming service is the first application scenario for Vsim technology.
Router. Huawei brand router product line is quite rich, for differentDemand users have coverage, its wireless transmission rate is fast, wide coverage, good stability. For example, Huawei's latest Wi-Fi 6 router can meet the wireless network needs of the home or small office. Wireless card. Huawei's wireless network cards have excellent performance and are suitable for a variety of devices, including laptops, desktops and mobile devices.
Wireless products refers to electronic and electrical products with wireless modules, the common range of wireless products is very wide, including we often say Bluetooth products, common wireless headphones, wireless audio, wireless routers, wireless keys and mice, wireless power cat, wireless network card and so onThese wireless products can be connected through wireless networks.
Wireless electronic products mainly include the following categories: wireless communication equipment, wireless computing equipment, wireless entertainment equipment and other wireless electronic products. Wireless communication devices: This category includes mobile devices such as mobile phones and tablet computers that can receive and send signals. These devices communicate over wireless networks, allowing people to make voice calls or data transfers from anywhere.
1,There are currently three mainstream wireless charging standards: Power Matters Alliance (PMA) standard: The Power Matters Alliance standard is initiated by Duracell Powermat, which is a joint venture between P&G and Powermat, a wireless charging technology company, and has a relatively outstanding comprehensive strength. In addition, Powermat is a supporting member of the Alliance for Wireless Power (A4WP) standard.
2, the current mainstream wireless charging power standard is 10W, corresponding to 5V2A charging specifications. The wireless charging power supported by Apple phones is also generally in line with this standard. Some devices may support lower power, such as 5V5A, corresponding to a 5W charge rate. In contrast, the power of wired charging is usually around 18W, and the speed of wireless charging is indeed slower.
3, there are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric field coupling charging, the mainstream standards on the market mainly Qi standard,PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology. Let's take a look at the principle of wireless charging.
4, wireless fast charge mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed. The principle of fast charging of mobile phones is to increase the input value of the charging voltage or current. But to really realize the fast charge of the mobile phone, it also needs a matching circuit andHardware.
5, the mainstream wireless charging standard Qi standard. Qi is the world's first standardization organization to promote Wireless charging technology - Wireless charging Alliance (Wireless Power Consortium, referred to as WPC) launched the "wireless charging" standard, with convenience and versatility. First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger.
1. RCUThe abbreviation of the English Room Control Unit means "room controller", which is a special term for middle and high-end hotels and smart buildings and smart home industry. Among them, the hotel deploys the room control system to use more. RCU has micro-processing function, that is, integrated MCU (Micro Control Unit) Chinese name is called microcomputer control unit, can wirelessly control all guest room electrical appliances, lamps and sockets.
2. The English abbreviation ADKC/RCU usually stands for Automatic Key Distribution Center/Rekeying Control Unit, Chinese literal translation of automatic key distribution center /Rekeying control unit. The term is primarily a government and military acronym used to describe the management and encryption functions of a critical device or system.
3, the remote concentrator (RCU) allows packet terminal and non-packet terminal access, has the procedure conversion function, you can centralize each terminal access to the packet switch on the medium and high speed line interleach multiplexing. The packet mount and dismount device (PAD) will come from an asynchronous terminal (non-packet terminal)After removing the start and end bits, the character information is assembled into packets and sent to the packet switching network. On the receiving end, the packet information is restored to characters and sent to the user terminal.
4, the main parameters of RCU are as follows: Working voltage: AC200V to AC240V, suitable for standard household power supply. Rated power: 16W, to keep the equipment low energy consumption. CPU configuration: Has three cpus, the main frequency is 24M/12M, providing efficient processing capacity. Operating temperature range: 0 ° C to 70 ° C to ensure the stable operation of the equipment under various climatic conditions.
