【 Weak current College 】 used mobile phones to control home

Future maybe can see the wisdom through PC or mobile phone, household appliances control with a problem, our California red karaoke attempted to import a song through a Bluetooth mobile phone.

Universal remote control concept, is the dream has always been on the market, a few can simultaneously control television and player, audio, and more universal, but the use of infrared transmission of traditional remote control, can transmit information only so little, a directive, an action, and we should have some experience, like I used to cool remote control no alignment, while the Show startup screen, air-conditioning in fact did not receive the signal, hot half minutes to note that no press the remote control. Radio communication to be used as remote means of communication, but also for a long time, but early in the development of radio communication, remote control does not, mainly because the author is in respect to the local analysis, mainly because of cost, remote control infrared communication cost is not high, homes need remote control products or more, the remote control does not need to have the capacity, two-way communication with another important reason was the lack of standards of wireless communication.




A family there is much you want to remote control? try count look XD


But now the situation changed, set of sentence advertisements: technology always comes from the people (lazy?), home of the digital electronic products more and more, people are increasingly lazy, like good fun inside the fate of that class, as demonstrated by the people for remote control of desire, longing for a can control all of the remote control. In addition, because of digital home concept, infrared remote control does not have the ability to walk across the floor, and sometimes want to the operation of the machine in the next room is also not convenient. The other is now increasingly focused on bi-directional communication needs, such as the Bluetooth headset now many appear caller ID, or display the contents of the music played, at this point, the only shipping simple messages of infrared remote control, of course, is not suited to this type of universal remote.

Previous years have been an interesting news, our karaoke trade with Bluetooth mobile phone to download the program, you can use Bluetooth cell phone as a remote control for the song, and can see the form on your phone. Alternative to General Bluetooth remote control has a fatal problem, that is a standard Bluetooth power is large, but to the needs of the remote control, power, at least to be able to maintain a few months, even years, for these reasons, will be next year's upcoming birth of low-power standard, for ultra low flow development of Bluetooth low power consumption, use even less than the standard Bluetooth protocol that can be greatly reduced power consumption.


Wii joystick is using Broadcom Broadcom Bluetooth chip, came with a title, PS3 chips is CSR.

Through Bluetooth remote control for low-power technology, still maintaining Bluetooth equipped with two-way communication capabilities, and can make use of the frequency control products, and have little opportunity to simultaneous control of two different products, and does not need much bandwidth transmission of information, there is no need to worry about whether the band conflicts; and as a universal remote control, as long as there is a similar to a new cell phone MOTO touch switch on it, in the background shows a different base diagram, you can control the different products. Even in the future, the development of a Java control platform, as long as the support for Bluetooth low power and the ability to open Java appliance, from cell phones to laptops, can take to control home appliances, and through bi-directional message transfer, you can see for example listings, play music, volume, temperature, etc., and air-conditioning.

However, because the standard product next year will be officially released to manufacturing, so at present we can only look at the application example figure too dry addiction Lulu ~ future opportunities getting more data and then to continue to talk about this technology standard chatter.
