The use of electromagnetic induction principle for charging equipment, the principle is similar to the transformer, through the transmitter and receiver end set coils, the transmitter coil under the action of power to send electromagnetic signals, the receiver coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
Wireless charging, also known as inductive charging, non-contact inductive charging, from the wireless power transmission technology, is beneficialWith near-field induction, that is, inductive coupling, energy is transmitted by the power supply device (charger) to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the device that uses electricity. If the distance between the charger and the electrical device is farThe same: Bluetooth headset is the application of Bluetooth technology on the hands-free headset, the user can not be tied to the pesky connection, in a variety of ways to easily talk. Wireless headsets are where the middle line is replaced by a wave that connects from the audio outlet of the computer to a transmitter that sends the radio waves to the headset of the receiver, which is equivalent to radio.
The difference is that the real wireless Bluetooth headset does not have any connection between the left and right ears, while the Bluetooth headset (sports headset, headset) has a short connection between the left and right ears. In terms of wearing experience and ease of use, real wireless headphones are more convenient than Bluetooth headphones. Ordinary Bluetooth headsets are generally divided intoThe primary headset and the secondary headset are fixed.
The difference between tws and Bluetooth earphones is as follows: TWS earphones belong to the category of Bluetooth earphones, the main difference between the two is true wireless and charging mode, TWS Bluetooth earphones do not need wired connection, get rid of the shackles of ordinary Bluetooth earphones wired; The left and right two earphones form a stereo system through Bluetooth, which improves listening, talking, and wearing. TWS earphones support wireless charging and charging box power supply. In terms of battery life, it is stronger than ordinary Bluetooth headphones.

The differences between wireless AC controllers and routers are: different functions, different application ranges, and different IP addresses. Different functions Wireless AC controller: WirelessThe AC controller provides the functions of delivering configurations to different aps, modifying configurations, intelligent RF management, and user access control. Router: The router provides data channel functions and control functions.
Therefore, the AC controller is not a router, the router is not an AC controller, they have different functions and roles.
Centrally manages and optimizes multiple aps in the region. Different from routers, AC controllers have the characteristics of unified management, automatic management, performance optimization and easy operation. For example, it can uniformly configure 1000 aps and automatically assign IP addresses and messagesDetect faults and send notifications while optimizing network performance and simplifying deployment and maintenance.
AP), each AP is solely responsible for RF and communication work, its role is a simple, hardware-based RF underlying sensing device, all Fit AP received RF signals, after 8011 encoding, then through the encryption tunnel protocol developed by different manufacturers through the Ethernet network and transmitted to the wireless controller. Then the wireless controller performs the encryption, verification, security control and other higher level work.
This is different from a home routerSomething else. The AC controller is used in wireless coverage to centrally manage all aps, and his responsibility is to manage aps. Routers are used for data communication. Although some AC controllers have the functions of routers, they are not as powerful as routers at all, and only some simple routing functions can be used in places with low requirements. In places with high requirements, the router cannot be replaced.
