The control modes of water fountains
1. Manual control: it is the simplest way of control, mainly used for the control of fixed styled fountain. By setting the dynamic switch on the power supply circuit of the fountain actuator, the operation and stop of the fountain equipment are controlled.
2. The program controlled: loop changes or remains unchanged through the preset operating state of the controller. For some links that require quiet and inappropriate use of music fountain, many fountains are used, such as hotel lobby, garden, residential area, etc. In addition, due to the low cost of program controlled fountain, such fountains can be considered when the budget is limited or the scale is small.
3. Clock control: This is also a control mode often used in the fountain, usually with the following three forms: using a programmable controller to automatically circulate according to a predetermined program, change various lights in time, control the motor of the submersible pump, turn off the solenoid valve, make the lighting and modeling harmonically and harmonically; use the electronics. The program controller controls the color lamp and the pump. The program controller can set the length of time arbitrarily; the time relay, the intermediate relay and the contactor are used to control the color lights, the pumps and the solenoid valves. Compared with the 3 ways, the programmable controller is flexible, reliable, and easy to change the program, but the price is high. The electronic program controller is composed of electronic circuits such as digital clock, counter and so on. It is easy to change the time and the price is low, but the time adjustment range is limited.
4. Music control:
a. real time audio control: this method is suitable for some scene singing, through the real time change of the water shape with the music signal, add glory to the singing scene, and enrich the form of the music. Through real-time collection and analysis of live music signals, the shape of water is changed with music rhythm, music frequency and signal intensity. This control method needs to match some recognized music elements with the specified water form in advance. During the real-time audio control process, when the controller identifies a specific musical element, it will control the corresponding water movement. The controller can receive the microphone input and receive audio signals such as CD player, radio, recorder, TV, and so on, for real-time signal recognition and fountain control.
b. expert system: the real time sound controlled fountain can realize the real time movement of the water shape with the music signal, but its disadvantage is that the change of the water shape is relatively monotonous, the expressive force of the music connotation is not rich enough, and the change of the water shape is relatively simple. In fact, the understanding of music varies from person to person, and people with high music accomplishment have a deeper understanding of music. In addition, the understanding of music is closely related to people's mood and surroundings.
