The present invention relates generally to systems and methods for making artificial snow. More particularly, this invention relates to automated systems for controlling the making of artificial snow. Still more particularly, the snowmaking automation system of the present invention provides remote automated control of snowmaking guns, compressed air sources and water hydrants arbitrarily located at a ski resort.
Snowmaking equipment is commonly used at ski resorts to supplement natural snowfall when needed to adequately cover ski slope terrain otherwise covered with dirt, surface plants, gravel, rocks and other debris that prevents safe skiing or boarding on snow. Snowmaking equipment always requires a source of water from which snow may be created from atomized mists of water droplets that may, or may not, be seeded with nucleating ice crystals. Some snowmaking equipment requires electricity to run fans or operate equipment controls, data logging or other purposes. Still other snowmaking equipment may require a source of compressed air used to accelerate atomized mists of water droplets and optionally the nucleating ice crystals into the atmosphere so that the water droplets can freeze in the air before falling to the surface intended for the artificial snow.
Snowmaking guns, such as those offered by Snow Logic, Inc., Park City, Utah, typically require a source of water and a source of compressed air to operate. The water source may be a physical pipeline that has been installed to a key location on a ski slope for the purpose of snowmaking. Alternatively, a well, temporary pipe, water hose, or any other suitable water source may be used for snowmaking. Typically, the water source must be pressurized to deliver it to a particular elevation and for use in pressurizing or charging the snowmaking gun. Some conventional water sources may be a creek, reservoir or well from which water may be extracted and pumped, typically at a pump house, through a fixed, preferably buried pipeline up along a ski run with periodic hydrants (vertical pipes) that provide water at the surface for snowmaking.
Similarly, the compressed air source may be a compressed air pipeline, air hose, air compressor, or other suitable compressed air source that has been located adjacent to or near the desired location for snowmaking. Some conventional snowmaking systems have compressed air pipelines that may parallel the water pipelines, e.g., 2-3 feet apart up a ski slope, and again, preferably underground, e.g., about 4 feet below the surface. Pressurized air discharged from an air compressor is generally too hot at about, 180-200° F., for use in snowmaking. So, the heated compressed air may be initially cooled by a primary cooling device known as an aftercooler. The aftercooler may consist of pipes surrounded by cold water through which the air passes and cools. The cooling of the air may also cause condensation of the air's moisture which must also be removed to prevent frosting of the air hoses used subsequently to deliver pressurized air to a snow gun. So, the cooled air with some moisture removed leaves the aftercooler and may enter a secondary cooling device, known as a stripping tower. The stripping tower in essence freeze dries the cooled air and further removes moisture. The colder compressed air leaving the stripping tower may have dropped in temperature to a range of about 45-55° F. The compressed air and pressurized water pipelines may also serve to further reduce the temperature of both to a temperature range of about 34-35° F., and may further dry the compressed air, if uninsulated pipes are used. However, a water droplet passing through a conventional snow gun may range from 34-44° F. depending on how the water is sourced.
The snowmaking gun used to make artificial snow may also be used in combination with a hydrant for controlling the water source and for controlling the compressed air source. Snow Logic, Inc., offers a dual auto hydrant that can safely control both the water source and compressed air source feeding a snowmaking gun.
Conventional snowmaking guns and hydrants are typically manually operated by snowmaking staff at a ski resort. It is generally time consuming for ski resort staff to travel to any and all of the various locations on a given mountain where snowmaking equipment is located. Additionally, the ideal time to operate snowmaking equipment may be anytime during the day or night as long as the ambient temperature and snowmaking conditions are correct. Consequently, there may be undesirable labor costs associated with snowmaking. But, these are not the only problems associated with conventional snowmaking systems and prior attempts at automating the snowmaking process.
Another problem with conventional fixed location snowmaking automation is that it may rely on buried or above ground power to operate the system and actuators. Such automation is “fixed” because it is tied to the fixed location of the buried or above ground power source used to operate the system. The cost of electrical infrastructure necessary to automate every possible location where snowmaking is desired on the mountain of a ski resort is expensive and invasive to the environment. Many snowmaking guns at ski resorts do not have such electrical infrastructure. Yet another problem with conventional fixed location automation used by ski resorts is that it typically only runs an average of 110-160 hours per season. Depending on the cost of such fixed automation, this may result in a long duration (perhaps years) before reaching a return on the investment. Still another problem with such conventional fixed location automation systems is that repair and maintenance of such fixed location automation systems generally must be carried out in the field, i.e., on the mountain.
Additionally, resorts may not have trained or experienced staff to troubleshoot and repair fixed snowmaking automation systems. There is a significant labor cost associated with hiring, training and maintaining qualified staff, or hiring outside technicians to troubleshoot and repair fixed snowmaking automation systems. There will always be a need to troubleshoot and repair snowmaking automation over time during actual use. For example, any kind of snowmaking equipment may be subject to malfunction from electrical (lightning strikes) during storms or mechanical (frozen pipes, avalanches, etc.)
Conventional hydrants and their associate valving, if not properly drained when not in use, can become dangerous. For example, on Dec. 7, 1998, Kevin E. Turner, Environmental Manager, Homewood Ski Resort, Homewood, Calif. (west shore of Lake Tahoe), was severely injured when a brass ball valve installed between a hydrant and a snow gun failed because water froze inside the valve and caused the valve cap to partially separate from the valve body and ultimately exploded because of unreleased compressed air. Kevin E. Turner v. Northern Indiana Brass Co. d/b/a NIBCO and Western Nevada Supply Co., No SCV 9387, 2009 WL 132814 (Cal. Superior).
Finally, conventional snowmaking automation tends to be proprietary as it is made for a particular type (gun or fan) and brand of snowmaking gun. Thus, implementing snowmaking automation at a given resort becomes costly and difficult because the conventional snowmaking automation systems are generally tied to the particular guns already installed. Snowmaking automation is also expensive when replacing existing equipment with new equipment that supports the desired automation.
Accordingly, there exists a need in the art for automated snowmaking equipment for automatically generating artificial snow using hydrants and snowmaking guns, that reduces ski resort labor costs, solves at least some of the above identified problems with conventional fixed automation systems, and provides greater control over the snowmaking process.
An embodiment of a snowmaking automation system for remotely controlling the generation of snow is disclosed. The system may include a hydrant for selectively receiving and delivering pressurized water and compressed air. The system may further include a snowmaking gun coupled to the hydrant to selectively receive the pressurized water and the compressed air. The system may further include at least one automation module coupled to the hydrant or the snowmaking gun, each of the at least one automation modules having a means for communication and a motor for actuating the snowmaking gun or the hydrant to selectively generate snow using the water and the air. The system may further include a base station in communication with the at least one automation module, the base station configured to provide a user control of the at least one automation module and thereby remotely control generation of the snow.
An embodiment of a snowmaking automation module is disclosed. The module may include a housing with an actuator interface for attachment to a snowmaking gun or a hydrant. The module may further include a gear motor mounted inside the housing and coupled to the actuator interface, the gear motor configured to selectively drive a snowmaking gun or a hydrant. The module may further include a radio modem and antenna mounted inside the housing. The module may further include a battery mounted inside the housing, the battery coupled to, and configure for powering, the gear motor and the radio modem.
Additional features and advantages of the invention will be apparent from the detailed description which follows, taken in conjunction with the accompanying drawings, which together illustrate, by way of example, features of embodiments of the present invention.
The following drawings illustrate exemplary embodiments for carrying out the invention. Like reference numerals refer to like parts in different views or embodiments of the present invention in the drawings.
Embodiments of the invention include a snowmaking automation system for use with snowmaking guns and hydrants. Embodiments of the snowmaking automation system described herein may be battery powered, and thus do not require fixed electrical infrastructure, but are designed to use such infrastructure if present on the mountain. The battery life is designed to operate the actuator for 150-200 hours before recharging according to embodiments of a snowmaking automation system of the present invention disclosed herein. This range of time is typically required to complete a batch of snowmaking on a given run at a resort. Some embodiments of the snowmaking automation system are also wireless, and thus, do not require hard-wired communications between base stations and remotely controlled snowmaking guns and hydrants. Another advantageous feature is the anticipated lower cost of operation of the various embodiments of a snowmaking automation systems of the present invention.
Another advantageous feature of the snowmaking automation system is that the actuators employed are modular and can be exchanged between embodiments of the snowmaking gun and embodiments of the hydrant. This level of actuator modularity makes for simpler maintenance, because the actuators are both identical, thus two different actuators, and the associated duplication of inventory, are unnecessary. The embodiments of actuators of the present invention may be swapped out on the mountain and brought back to a workshop for repairs and maintenance. Alternatively, the actuators may be sent back to the manufacturer for repairs eliminating the need for an in-house technician at the resort. The automation modules may be swapped out based on battery charge (need for recharging) or repairs (malfunctions) or scheduled maintenance. For example, damaged automation modules may be swapped out in the field with a replacement. The state and condition of the individual actuators can be tracked in real-time via the snowmaking automation system of the present invention.
According to one embodiment, the actuator on a Snow Logic snowmaking gun is capable of supplying power (24v) and control signals to a Snow Logic dual auto hydrant, thereby eliminating the need for a radio modem and battery associated with the dual auto hydrant actuator.
Still another advantageous feature of embodiments of the snowmaking automation system of the present invention is that it communicates via a radio network. However, embodiments are also capable of communication by a “hard-wired” link, e.g., Ethernet, optical fiber, twisted pair or any other suitable network cabling if already present at a fixed location on the mountain.
According to another embodiment, each actuator may have an onboard Global Positioning System (GPS) module so that each automation module may be physically tracked by the snowmaking automation system of the present invention, for example by a master control computer. This feature is particularly useful, e.g., in determining the location of a module that needs servicing or recharging.
Yet another advantageous feature of embodiments of the snowmaking automation system employing GPS modules of the present invention is that water pressure sensors may become unnecessary for each snowmaking gun at each individual location. This is because the water pressure may be obtained by measurement from the pump house (original water source) only and then extrapolating pressure by using GPS altitude. This can reduce overall system cost by eliminating water pressure sensors.
Another advantageous feature of embodiments of the snowmaking automation system of the present invention is that there is virtually no limit on the number of adjustments of snowmaking parameters that may be made during a given snowmaking production run. In contrast, manual adjustment by a technician on location at the snowmaking equipment on a mountain typically only occurs 2-5 times per night. By removing the adjustment limitations inherent in manual systems, snowmaking production may be optimized and maximized, while reducing costs. This feature improves snow making production capabilities and snow quality. According to one embodiment, the snowmaking automation system of the present invention is capable of making adjustments to the snowmaking parameters every 15 minutes as ambient conditions change.
Embodiments of the snowmaking automation system of the present invention in combination with a Snow Logic dual auto hydrant provide the capability to automate any conventional type or brand of air water snowmaking gun. This feature is believed to be a first in the industry. Thus, embodiments of the snowmaking automation system of the present invention used in conjunction with a Snow Logic dual auto hydrant can be used to retrofit existing conventional air and water snowmaking systems with automation. This allows for a master control computer (base station) within the snowmaking automation system of the present invention to control different brands and types of snowmaking technology.
It will be apparent that various configurations of the snowmaking automation system of the present invention can be made to suit particular needs of a given resort. For example, the automation may be used to automate the hydrant and leave the gun in a manual configuration, or the reverse, where the gun is automated and the hydrant is manually operated. Of course, the most flexible control occurs when both the gun and hydrant are automated.
Finally, because of the modularity of the snowmaking automation system of the present invention, there are various business models that could be employed with the deployment of such snowmaking equipment, e.g., direct sales to the resort, rental or leasing of the equipment to the resorts. This feature gives ski resorts great flexibility in how they choose to implement snowmaking automation and control over their direct labor costs.
The terms “snowmaking gun” and “snow gun” are used interchangeably herein and are understood to be a device configured to convert water to snow under the appropriate atmospheric conditions. Exemplary snow guns are available from Snow Logic, Inc., Park City, Utah, and may be as described in U.S. Pat. No. 9,170,041 to Dodson. The terms “automated actuator”, “snowmaking automation module” and “black box” are also used interchangeably and synonymously herein and are understood to be a device that may be interchangeably attached to either a snowmaking gun or a hydrant through a common actuator interface according to the embodiments of the invention disclosed herein. This interchangeable feature of the automated actuator or snowmaking automation module is believed to be a unique and useful feature that provides greater flexibility in implementing, servicing and maintaining a given snowmaking automation system.

System 100 may further include a base station 112 that is in communication 116 with one or more (one shown) repeater nodes 114 and is also in communication 118 with the one or more snowmaking guns 102. The communications 116 and 118 may be wireless or wired depending on the particular embodiment. Of course, the wireless communication (106, 116, 118) embodiments offer the greatest flexibility in terms of locating the gun 102 and hydrant 104 on a given mountain location (not shown).
The repeater nodes 114 are used to provide wireless connectivity between the base station 112 and each snowmaking gun 102 and hydrant 104 in the varied topography that one might encounter on a mountain resort ski slope. Each repeater node 114 operates much like a cellphone tower to provide geographic coverage of the wireless network. The repeater nodes 114 may be located anywhere on the mountain and used to provide full coverage of terrain that is subject to snowmaking. The repeater nodes 114 may operate at any suitable radio frequency (RF) or band of frequencies and use any suitable communications protocol. The repeater nodes 114 may be portable or fixed in physical location according to other embodiments of the present invention.
Another advantageous feature of embodiments of the snowmaking automation system of the present invention is that the RF repeater nodes 114 may be employed to cover any mountainous terrain with a wireless network for use by the snowmaking automation system. Dead spots and optimal placement of repeater nodes 114 may be determined by any suitable RF signal detector (not shown). Such an RF signal detector may be designed and used to audit the locations of snowmaking equipment, e.g., snowmaking gun 102 and hydrant 104, to easily determine dead spots (no wireless network signal) and preferred placement of portable RF repeater stations for complete network coverage on the mountain. For example, the RF signal detector may be backpack mounted or hand carried for skiing or snowshoeing over ski trails to snowmaking locations, or otherwise mounted on a vehicle, snowmobile or snow cat to perform such a network audit as well as for initial repeater node 114 placement.

According to a hard-wired communication 324 embodiment, power, optional data and control signals may be transmitted between processor 302 and hydrant 326 via a waterproof connector 328. Processor 302 may further be in communication 332 with a temperature and humidity sensor 330. The temperature and humidity information from sensor 330 may be transmitted back to the base station 112, 200 for adjusting snowmaking parameters of the guns 102 and hydrant 104
Processor 302 may further be in communication 338 with a user interface 340. The user interface 340 may be a dedicated weather-proofed panel configured with LED indicators, buttons, switches, test points and anything else used to control the module 300. The buttons may be used to manually open, or advance, the valve, manually close the valve, test the communications link, and to obtain battery status. LED indicators may indicate gun valve positioning (1-4 for a 4-step gun), communications signal connection and signal strength, GPS communications, etc. Alternatively, user interface 340 may be a touch panel configured appropriately to manually control the snowmaking gun 102, according to another embodiment. The configuring and programming of a touch panel is within the knowledge of one of ordinary skill in the art, and thus, will not be further elaborated herein.
A particularly useful and novel feature of one embodiment of module 300 is that it can be battery operated for between 150-200 hours on a single charge. As shown in

Processor 402 may be further connected 420 to a user interface 418. The user interface 418 may be a dedicated weather-proofed panel configured with LED indicators, buttons, switches, test points and anything else used to manually control the repeater 400. For example buttons may include a button for testing the communication link. LED indicators may include communications OK, power indicator, RX LED and TX LED for indications regarding the receiving and transmission of data. Alternatively, user interface 418 may be a touch panel configured appropriately to control repeater 400. Again the configuring and programming of a touch panel is within the knowledge of one of ordinary skill in the art, and thus, will not be further elaborated herein.
Power to drive the repeater 400 may come from power mains 422 available at the location on the hill where the repeater 400 is installed. Alternatively, power may be supplied by a battery (not shown), according to another embodiment. Thus, repeater 400 may also be located anywhere and moved if necessary. Power circuitry 424 may be used to condition the power from the power mains 422, or battery (not shown) prior to distribution to the processor 402, radio 404, and anything else that needs powering within repeater 400.
