How will IC chip change our life

The era is in progress, people's demand for daily necessities is more inclined to convenience and humanization, and the traditional simple electronic lock is only limited to the simple buzzer alarm sound, even the buzzer alarm sound is not, directly light a light. But these simple buzzers sound alarm or light, can you know what is wrong with it, is the lack of power need to change the battery or other problems?

In the electronic lock into the voice chip and has been added voice prompt function, in addition to the simple fault prompt, but also to do business promotion, such as boot language can be "XX intelligent lock wish you a happy life" and so on, voice content can be customized according to customer requirements!

For the voice chip scheme of intelligent lock, the following schemes are recommended:

Intelligent lock voice IC QGPH5020 scheme, but the expansion of FLAS can support 102040 seconds of sound, using the frequency of 6Khz calculated sound length), expansion of external NOR SPI FALSH to expand the length of speech playback (maximum support 128Mbit) can support 5592 seconds of sound playback. A class B amplifier or PWM output can drive 8R/ 0.5w speaker, 16-bit D/A audio output, built-in OP BTL audio amplifier, and pre-amplifier filter, working voltage 2.2-3.6v, key trigger, I2C trigger, CPU serial port, CPU parallel port, user-defined trigger mode.

There are many kinds of electronic lock: hotel intelligent electronic lock, wardrobe intelligent lock, password lock, fingerprint lock, etc., but no matter what you do is what lock, add a voice prompt or humanized, also can bring a lot of convenience! In security engineering, the lock product of access control system is an important equipment related to the safety of the whole system, so the quality of lock product is also related to the quality and acceptance of the whole security engineering. Newly developed contactless IC card intelligent door lock, contactless IC card intelligent door lock, TM card intelligent door lock and electronic double control intelligent door lock, fingerprint lock, password lock, and other high-end locks can be changed into voice prompt alarm. With the deepening of China's opening to the outside world, the development of high-grade buildings is accelerating, and the prospect of high-grade lock market is optimistic. China's lock industry on lock high-tech investment increased year by year, the market demand for high-grade locks also increased year by year.
