Background Technology

[0003] Typically, a fountain is a type of landscaping facility that sprays water stored in a reservoir through pumps and nozzles to provide surrounding spectators with both emotional comfort and a sense of coolness. However, there is a growing trend toward the widespread installation of musical fountain systems. These systems go beyond simply spraying water; they create dynamism and atmosphere through music, pump control, nozzle water spray direction control, nozzle water volume height control, and lighting control, thereby offering viewers both interest and visual enjoyment.

[0004] Generally, a musical fountain system extracts volume or amplitude representing the size and intensity of music, beat and tempo representing the beat, speed, and rhythm, timbre, and frequency from multiple digital or analog sound sources to control operation through corresponding operating signals for each device constituting the fountain, thereby producing fountain movements, spray heights, and lighting in accordance with externally output music. To produce fountains synchronized with externally output music, organic operation among fountain devices composed of multiple pumps, multiple nozzles, multiple nozzle drive motors, and multiple lights is required. However, as the musical fountain system is operated repeatedly for extended periods, errors may occur in the operation of the aforementioned fountain devices, or malfunctions may occur due to causes such as the inflow of contaminants like fallen leaves or soil from around the music system into the reservoir or the formation of sludge. Furthermore, due to the nature of fountain devices consisting of pipes and devices, a failure in any one of the fountain devices poses a problem where the failure spreads rapidly along the complexly interconnected piping, causing a chain reaction of failures in other fountain devices. To prevent this, there is a problem in that regular inspections covering the entire musical fountain system must typically be conducted frequently at short intervals. When conducting regular inspections, it is difficult to identify exactly which device has failed because the piping and numerous identical devices used to produce the musical fountain are installed in various locations, and there is a problem in that inspections and maintenance require a significant amount of time and cost.

[0027] Preferably, fragrance sprayers are provided at multiple locations around the perimeter where the musical fountain is equipped, so that viewers can simultaneously experience fun and interest by listening to music through the sound output unit while watching the fountain perform in sync with the music, and by amplifying lyrical emotions through the sense of smell via perfume sprayed from the fragrance sprayers in synchronization with the music. Additionally, mist sprayers are provided at multiple locations around the perimeter where the musical fountain is equipped, so that viewers can feel the coolness of the mist spray on their skin through the operation of the mist sprayers synchronized with the music, especially in hot weather.

[0029] The above fountain device operation control unit receives control signal data including control signals for each device constituting the fountain device unit from the above automatic performance generation unit, and outputs operation signals for each device of the above fountain device unit, such as the pump unit, nozzle unit, nozzle driving unit, lighting unit, electronic valve unit, and sound output unit, according to the received control signal data. The above fountain device operation control unit may be formed in the form of a control board equipped with a PLC (Programmable Logic Control), and may be provided between the above automatic performance generation unit and the fountain device unit to enable bidirectional communication with each device constituting the above automatic performance generation unit and the fountain device unit through an input and output interface, and receives control signal data from the above automatic performance generation unit and controls operation by outputting operation signals, such as contact signals, to each device constituting the fountain device unit.

[0031] The above automatic production generation unit receives sound source data from the sound source data extraction unit, calculates control signal data including control signals for each device constituting the fountain unit through the volume value, rhythm value, and frequency band value included in the received sound source data, and outputs the calculated control signal data to the fountain unit operation control unit. In one embodiment, control signal data can be calculated to control the operation of the pump unit and the solenoid valve unit so as to adjust the spray height of the nozzle according to the volume value included in the sound source data, control signal data can be calculated to control the operation of the nozzle drive unit according to the rhythm value to control the direction of water spraying, and control the operation of the solenoid valve unit to control the timing of water spraying and to produce a pattern in which a short stream of water splashes out for each rhythm, and control signal data can be calculated to control the brightness or color of the lighting unit and the direction of water spraying of the nozzle according to the frequency band value, that is, according to high, medium, or low tones, and the calculated control signal data can be output externally.

[0033] The above-mentioned fountain device sensor unit is equipped with a pump discharge pressure sensor on the water discharge side of each of the plurality of pumps included in the fountain device unit to measure and output the discharge side pressure value of each individual pump to the outside, a nozzle spray pressure sensor is equipped on the water spray end side of each of the plurality of nozzles to measure and output the spray pressure value when water is sprayed from each individual nozzle to the outside, an illuminance sensor is equipped on one side of the light projection surface of each of the plurality of lights to measure and output the illuminance value when the individual light is projected to the outside, and a position sensor is equipped on one side of each of the plurality of nozzles to measure and output the position movement value of each individual nozzle to the outside. Preferably, although not explicitly stated, a unique ID is assigned to each of the above-mentioned sensors, and each sensor measurement value is output along with the unique ID assigned to each sensor, thereby enabling individual identification of which sensor measured and outputted each sensor value. Furthermore, in the event that an abnormal condition is detected in the future, the location of the device where the abnormal condition occurred can be easily identified through a bird's-eye view, etc., that allows identification of the location where the individual sensor is installed, along with the unique ID of the sensor that is output externally due to the detection of the abnormal condition.

[0035] As illustrated in FIG. 1, the above-mentioned fountain device management unit receives values ​​measured by each sensor from the fountain device sensor unit, stores the received values ​​measured by each sensor internally for a predetermined period, calculates the average value of the values ​​measured by each sensor stored internally for the predetermined period, and after the average value of each sensor is calculated, compares the values ​​measured by each sensor input from the fountain device sensor unit with the average value of each sensor. If the difference between the measured value and the corresponding average value deviates from a predetermined range value received from the user during installation, the unit outputs sensor information regarding which sensor among the fountain device sensor unit the sensor deviates from the predetermined range value—namely, the average value, measured value, difference value, predetermined range value, unique ID, and location information of the sensor—to a monitor screen provided on one side, and simultaneously outputs an abnormal state warning sound to the outside. Upon hearing the abnormal state warning sound and recognizing the occurrence of an abnormal state, the site manager of the music fountain system By checking the sensor information displayed on the monitor screen of the fountain device management unit, moving to the device where the sensor with the abnormal condition is located, maintenance such as repair can be performed quickly, and the impact on the normal operation of other fountain devices caused by the failure of the device with the abnormal condition can be minimized.

[0037] Preferably, in a musical fountain system equipped with an automatic performance function according to the present invention, as illustrated in FIG. 1, a plurality of video recording cameras are each provided at predetermined positions around the musical fountain system to view the musical fountain produced by operating each device of the fountain unit according to the control signal data in synchronization with the sound source output through the sound output unit, thereby capturing the performance video of the musical fountain, and a musical fountain performance recording unit is configured to output the captured performance video of the musical fountain to the outside; a musical fountain performance state storage unit is provided to receive the performance video of the musical fountain from the musical fountain performance recording unit and receive control signal data calculated from the automatic performance generation unit; the received control signal data, the corresponding performance video of the musical fountain produced through the received control signal data, and the sound source data received by the automatic performance generation unit from the sound source data extraction unit for calculating the control signal data are stored; and a musical fountain automatic performance control unit is provided at a remote location from where the musical fountain system is installed so as to be able to exchange data with the musical fountain performance state storage unit. It is connected via wireless communication such as the Internet, and receives sound source data, control signal data calculated through the sound source data, and a video of the music fountain performance produced through the control signal data from the music fountain performance state storage unit, respectively, and displays them externally through a device such as a monitor; it receives control signal modification data, in which the control signal data calculated by the automatic performance generation unit through the sound source data is modified, from a music fountain director or others who have professional knowledge and experience in music fountain performance; and outputs and stores to the music fountain performance state storage unit the music fountain performance data formed from the sound source data received by the automatic performance generation unit from the sound source data extraction unit for the purpose of calculating the control signal data before modification, and the control signal modification data received modified from the music fountain director in correspondence with the received sound source data.

[0038] In the case of conventional musical fountain systems, sound sources and corresponding operation control signals from previous systems were uniformly used in musical fountain systems at different sites without considering the length or configuration of the piping constituting the system, the capacity of the water tank, or the surrounding environment. Consequently, there was a problem in that it was difficult to automatically perform musical fountain displays while taking into account changes in operating characteristics according to the construction environment and operating lifespan of each device of the fountain system.

[0039] Accordingly, the musical fountain system equipped with an automatic performance function according to the present invention enables a musical fountain director, who possesses extensive experience and professional knowledge in musical fountain performance, to verify through a monitor screen of the musical fountain automatic performance control unit located at a remote location far from the musical fountain system whether the control signal data generated by the automatic performance generation unit based on the sound source data, the control signal data generated by the automatic performance generation unit based on the sound source data, and the musical fountain performance video generated based on the control signal data, and to verify through the musical fountain performance video whether the control signal data generated by the automatic performance generation unit based on the sound source data is correctly generated. Furthermore, the musical fountain performance content intended to be implemented by the control signal data initially generated by the automatic performance generation unit based on the sound source data, as confirmed by the musical fountain performance video due to the influence of the length or configuration of the piping constituting the musical fountain system, the capacity of the water tank, the dynamic characteristics of the installed fountain device, or calculation errors of the automatic performance generation unit If the content of the performance differs from the above, the above music fountain director, etc., verifies the above music fountain performance video and inputs the modified control signal data, which is a modified control signal data produced by the above automatic performance generation unit. Together with the modified control signal data, the sound source data used to produce the control signal data recognized as an error before modification is matched to form music fountain performance data. The music fountain performance data formed from the modified control signal data and the sound source data corresponding to the modified control signal data is output and stored in the above music fountain performance status storage unit so that it can be used for the next automatic calculation of control signal data.

[0041] Preferably, the automatic performance generation unit compares the sound source data received from the sound source data extraction unit with the sound source data among the music fountain performance data stored in the music fountain performance state storage unit; if the difference values ​​between the volume value, rhythm value, and frequency band value included in the received sound source data and the volume value, rhythm value, and frequency band value included in the sound source data among the stored music fountain performance data are within a preset range, the automatic performance generation unit calculates control signal correction data corresponding to the sound source data among the stored music fountain performance data as control signal data, and outputs the calculated control signal data to the fountain device operation control unit so that the music fountain director uses the music fountain performance data stored after correcting the calculation error through the music fountain automatic performance adjustment unit, and by correcting and reflecting the calculation error and malfunctioning music fountain performance content discovered during initial operation, when sound source data containing similar values ​​for volume value, rhythm value, and frequency band value is input the next time, the calculation error and inappropriate music fountain performance content that is not synchronized with the output sound source By changing the length or configuration of the pipes constituting the musical fountain system, the capacity of the water tank, the dynamic characteristics of the installed fountain device, the calculation error of the automatic production generation unit, or inappropriate musical fountain production content that is not synchronized with the output sound source, control signal data can be automatically calculated to implement a more accurate and richer musical fountain production. Additionally, as the entire sound source changes, a beautiful musical fountain production can be automatically implemented that harmonizes with the surrounding environment where the musical fountain is installed.

[0043] Preferably, when the difference between the value measured by each sensor and the corresponding average value calculated by the fountain device management unit is small and falls within a predetermined value range received from the user, as illustrated in FIG. 2, the fountain device management unit does not emit a separate warning sound for the occurrence of an abnormal state externally, but outputs the difference value information regarding the device where the sensor with the abnormal state is located to the automatic performance generation unit. The automatic performance generation unit, having received the difference value information regarding the device where the sensor with the abnormal state is located, calculates a control signal for the device where the sensor with the abnormal state is located, which allows for the correction of the difference value that deviates from the predetermined range value received from the user during initial installation. It also calculates the control signal data including the control signal calculated for the difference value correction and outputs it to the fountain device operation control unit. This generates control signal data so that even when the operating amount of each device constituting the fountain device unit fluctuates due to prolonged repeated use or the influence of the surrounding environment, the automatic performance generation unit can take this into account and correct the fluctuating operating amount, thereby reducing the manpower and costs required for maintenance of the fountain device unit. It enables the automatic performance of the musical fountain to be carried out consistently and continuously while minimizing the effects.

[0044] In addition, if the difference value information received from the automatic performance generation unit exceeds a predetermined range of values, the automatic performance generation unit does not generate control signal data for separate correction, but immediately outputs an abnormal state warning sound generation signal to the fountain device management unit. Upon receiving the abnormal state warning sound generation signal from the automatic performance generation unit, the fountain device management unit immediately outputs an abnormal state warning sound externally, thereby enabling the field manager managing the musical fountain system to immediately take follow-up measures, such as repairs, regarding the relevant device of the fountain device unit.

[0046] As described above, the maintenance-friendly musical fountain system according to the present invention can easily detect whether an abnormal condition has occurred in fountain devices, such as a pump unit, nozzle unit, nozzle drive unit, and lighting unit, without conducting regular inspections by a field manager. When an abnormal condition is detected by the musical fountain system itself, the field manager managing the musical fountain system is notified that an abnormal condition has occurred in the fountain devices. Furthermore, the field manager can easily identify which device among the devices constituting the fountain devices has an abnormal condition by looking at a monitor screen at the site. The field manager, having identified the location of the device with the abnormal condition through an aerial view or the monitor screen, can quickly move to the device and easily take follow-up measures, such as repairs, at the site.

[0047] In addition, a fountain device comprising a pump unit, an electronic valve unit for controlling nozzle water spraying, a nozzle water spraying direction adjustment drive unit, a lighting unit, and a sound output unit can be synchronized with a sound source output externally through the sound output unit to control the operation of the fountain device and automatically produce a musical fountain. Furthermore, without visiting the site where the musical fountain system is installed, the system can automatically produce a musical fountain by receiving assistance from a remote expert, taking into account changes in operating characteristics according to the construction environment and operating lifespan of each device of the fountain device constituting the musical fountain system. Additionally, as the entire sound source changes, it becomes easy to automatically produce a beautiful musical fountain that harmonizes with the surrounding environment where the musical fountain is installed.

[0049] Although some embodiments have been described above by way of example, it is obvious to those skilled in the art that the present invention may be embodied in various other forms without departing from the spirit and scope thereof.

[0050] Accordingly, the embodiments described above should be regarded as exemplary rather than limiting, and all embodiments within the scope of the appended claims and their equivalents are included within the scope of the invention. Explanation of the symbols
