Remote Control Used to remote control machinery
remote control of each of us may have been used, then how does it work? Here is a brief introduction:
The remote control is a device for remote control of the machine. The modern remote control is mainly composed of integrated circuit boards and buttons used to generate different messages. Its launch principle is mainly through the infrared light-emitting diodes, which is actually a special light-emitting diodes, because of its internal material is different from the ordinary light-emitting diodes, so when at both ends of its application of a certain voltage, it is issued by the infrared Not visible light.
The remote control can be divided into two categories: physical remote control and remote control applications. Physical remote control is mainly remote control of the kind, such as air-conditioning remote control and so on. The remote control application is now mainly the Internet products, Apple stores and Andrews market can be found, is the software installed on the phone, and then you open the software when the phone will become a remote control to control the corresponding content The - all the things in the breeding of growth, from the original barren to the present colorful, so why is there such a change in the sky? The reason is very simple, because the environment changes and the need to evolve, and thus into this trend. Electronic products, such as remote control are the same, in this science and technology more and more developed society, if you keep the same, it is easy to be eliminated.
--- We all want to see a qualitative leap in development, so how is the remote control? Let us look at the following development process of remote control:
The earliest remote control is developed by an electrical company in the United States, is wired, this appearance is sometimes inconvenient to carry, and later there is a called "Flashmatic" wireless device introduced, but this device can not Whether the beam is coming from the remote control, and it must be aligned to control, so the inventors continue to update the device according to demand, developed a use of ultrasound to adjust the channel and volume, but its shortcomings will be General ultrasonic interference, but because of these remote control technology can not meet the needs of the public, and later a new product developed, it is a send and receive infrared semiconductor devices. Of course, other wireless transmission technology, such as Bluetooth, has been developed and is widely used.
