Foreword: With the improvement of people's living standards and the yearning to build a green city, the musical fountain has become an important product in the leisure and entertainment industry with its unique charm and special functions. The musical fountain can moisten the surrounding air and reduce Dust, lower the temperature, and the small water droplets of the fountain collide with air molecules, which can produce a large number of negative oxygen ions to emit soothing music, which is beneficial to improve the community's appearance and enhance the physical and mental health of residents, conforms to the modern life concept, and creates a good living atmosphere.
The music fountain integrates light, color and sound, that is, according to the special elements of music to control the operation and speed change of the fountain pump, combined with the change of light to form a fountain, choose Haiwell PLC to control the fountain control system, and realize the switch through the program The frequency of music is converted to control the changes of the fountain and the flashing lights. It is easy to use, reliable in operation, and simple in control program design. Haiwell PLC realizes the perfect control of sound, light and water of the music fountain.
The core system hardware of the music fountain uses Haiwell T60S2R+H36D0R+4 H36D0T+S04AI. The entire control system reaches more than 250 switch output points. Haiwell PLC has a large one-time communication capacity and switch points (such as X, Y, M). , T, C, SM) up to 255 or 16-bit data (such as V, SV, CCV, TCV, AI, AQ) up to 48. With such a large data reading capacity, third-party equipment (such as Computer) When sending commands to the PLC to read real-time data or set process parameters, the data to be monitored or set is communicated once, which reduces the number of communications, greatly improves the communication effect, and enhances the data Real-time and control real-time;
The music fountain real-time control system composed of Haiwell PLC and ordinary computer is adopted, and the advantages of Haiwell PLC's communication function are used to realize the communication and control between the upper computer and the lower computer. Haiwell PLC completes the rapid changes of various water types, lights, and running fountains in the real-time control of the fountain. Using Haiwell communication commands, no matter what communication protocol you use, you only need one communication command to complete complex communication functions. The programming is simple and the program is concise. There is no need to worry about communication port conflicts, sending and receiving control, communication interruption processing, etc. , You can mix and use various protocols in the program to easily complete the various data exchanges you need.
Each communication port of Haiwell PLC can be programmed and networked, and can be used as a master station or a slave station. Supports 1:N, N:1, N:N networking, supports various man-machine interfaces and configuration software, and can be connected to any third-party equipment with communication functions (such as inverters, meters, barcode readers, etc.).
