I. Project design background and overview
The family is the smallest unit of urban life, and the Chinese have spent their entire lives on buying and renovating. Commodity housing is not only expensive, but also because the decoration takes up too much space. After visiting the Suzhou Garden, we had the idea of ​​making a home landscape fountain, using a miniature musical fountain to bring a different style and taste to the home. The characteristic of Suzhou gardens is that they are small and big, and they are concentrated by the micro-group landscape to enrich the motherland and the mountains and rivers. Our fountain should be like this too. Imagine a small fountain in the tea machine in the living room, the water splashing between the rockeries, the fish flowing between the water columns... What an interesting scene, how much joy can be brought to family, children, guests and friends.
Second, the project design principle
1, an overview of the principle
The principle is to use the single-chip microcomputer to control the fountain action, the single-chip computer converts the input music signal or the pre-programming command, and outputs the control signal to the peripheral equipment such as the water pump, the nozzle solenoid valve, the light, the sound effect, etc., so that the regular combination action can realize the operation of the landscape fountain. .
2, the hardware design principle
The A/D conversion of the music signal is input into the MCU, and the I/O port of the MCU is used to output the high and low level control relays through music and programming. The relay pins are connected in series with the water pump, solenoid valve, diving lamp and speaker. Indirect control of water pump, solenoid valve, diving light, speaker action, and human-computer interaction through remote control.
3, software design principles
The software mainly implements two control modes: music control and programming control. The music control mainly compares the level of the input music digital signal, and realizes the synchronous control of the peripheral circuit according to the input level high and low synchronous output level; programming control It is mainly to design several sets of algorithms, which can achieve a regular or completely random combination of peripheral devices.
