## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. application Ser. No. 16/181,279, entitled “Smart Pool Skimmer with Cloud Based Pool Monitoring System” which claims the benefit of U.S. Provisional Application No. 62/582,104, entitled “Smart Pool Skimmer with Cloud Based Pool Monitoring System” filed on Nov. 6, 2017, and assigned to the assignee hereof, the content of which is hereby incorporated by reference in its entirety.


INTRODUCTION
Field of Disclosure
Aspects of the present disclosure relate to monitoring pool conditions, and more particularly, to a smart pool skimmer that monitors pool conditions using a plurality of sensors.
Description of Related Art
Improperly treated pool water leads to the proliferation of algae and bacteria in addition to other free radicals. Common water sanitation methods are based on chemical sanitizers which must be maintained at constant concentration levels for proper effectiveness.
At current, the most practical way to determine chemical balance of the pool water has been through chemical testing kits, or test strips by visual color indicators. This method requires that the actor manually take a water sample from the pool, apply an agent and reactant, and physically observe the color outcome compared to a reference color to determine the active chemical composition. Some electrical monitoring systems have begun to appear in the market, however; they feature floating apparatuses and that are capable of measuring pH and oxidation reduction potential (ORP).
Electronic sensors such as an ORP sensor have been successfully utilized as a standard for measuring water quality. Research has shown that an ORP value of 650 to 700 mV, free-floating decay and spoilage bacteria as well as pathogenic bacteria such as E. coli or Salmonella species are killed within 30 seconds. This skimmer plate, for example, takes advantage of the ORP process to determine chemical availability in the liquid or pool.
Pool water evaporation is a longstanding problem for pool owners. Studies have shown that pool water evaporation can exceed 1⁄4 to 1⁄2 inch per day. Current products to maintain pool water level have proven unreliable and prone to failure over time, and add-on devices create an unsightly clutter of hoses and valves around the pool.
Solid state water level sensors are quickly becoming a standard for highly accurate water level measurements. The skimmer plate sits in a fixed and static position providing the skimmer plate an excellent opportunity to take highly accurate water level readings through in integrated design. Utilizing cloud-based machine learning, and an automated refill valve, predictive water level maintenance is achievable.
The primary function of a conventional pool skimmer cover plate is to prevent objects from falling into a pool filter basket. A pool skimmer cover plate typically provides a barrier to an otherwise open cylindrical hole near the pool. Partial purpose of this disclosure is to utilize the strategic location of the cover plate, and/or skimmer with a combination of electronic sensors and machine learning software to source and monitor data on pool water conditions compared to other aforementioned solutions that float in the water and are susceptible to problems, such as being caught in debris or the skimmer itself.
There are typically two suction points on common in-ground swimming pools, the floor suction and skimmer(s) suction. This solution is particularly applicable to the skimmer suction and/or covering plate of the pool skimmer.

It should be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of a claim. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any aspect described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over the other aspects.
The smart pool skimmer constructed in accordance with this disclosure includes a device designed as part of, or integrated with a pool skimmer. The smart pool skimmer may be sized and shaped to replace an existing skimmer cover plate for an in-ground or above ground pool. An exemplary embodiment of a smart pool skimmer designed to interface with an existing pool skimmer and a lower body enclosed with electronics and sensors to monitor conditions of the pool, is shown with reference to FIGS. 1A through 1D and FIG. 2. The arrangements as shown below illustrate an embodiment of the smart skimmer in the configuration of a skimmer cover plate.
FIG. 1A is a top view of an exemplary embodiment of the smart pool skimmer 100, in accordance with certain aspects of the present disclosure. In the exemplary embodiment, the smart pool skimmer 100 has a body housing that includes a body housing comprising a top cover 1, lifting slots 2, a solar panel 3 and indicator light pipe(s) 4. The solar panel 3 as shown is embedded into the top cover 1, sealed and connected to the underside electronics compartment, and in other embodiments, the solar panel 3 can be replaced by other mechanisms for charging a rechargeable battery or by replacing the power source of the smart pool skimmer 100. The lifting slots 2 provide a mechanism to lift the smart pool skimmer 100 from an existing skimmer.
FIG. 1B is a top perspective view of an exemplary embodiment of the smart pool skimmer 100, in accordance with certain aspects of the present disclosure. FIG. 1B illustrates the sensor enclosure fairing (6) for sensors of the smart pool skimmer 100. This fairing comprises a non-watertight snap fit feature designed with vent holes to allow for the unobstructed flow of water. The fairing is also designed to prevent debris and unwanted materials from collecting around the sensors.
The sensors (not illustrated in FIG. 1B), which are both digital and analog depending on their function, provide information about pool conditions, including pool water chemistry, water flow, water lever characteristics, wave interactions, and obstructions in the skimmer and other environmental conditions of the pool or spa. All measurements are gathered from electronic signals which are generated from the sensor(s) that extend away from the body housing. A microcontroller (not illustrated in FIG. 1B) located inside the body housing connects to the sensors. The microcontroller stores data locally or sends the data to the cloud when a Wi-Fi, Bluetooth or cellular connection is present. The data is aggregated and stored in the cloud for further analysis and visualization of trend-based characteristics. Data aggregation, storage, and analysis in the cloud are discussed in further detail below.
In an exemplary embodiment, one of the sensors detects ORP. ORP is directly related to the concentration and activity of water sanitizer and has been recognized as a standard indicator of water quality and is used to inform the user about the state of water quality. The ORP readings in millivolts are translated into simple measurements for a homeowner or serviceman to determine whether the water is safe and whether chemicals need to be added or diluted. ORP sensors are currently available in market and can monitor water on a continuous basis with accuracy. They provide the oxidation-reduction potential of a sanitizer, such as chlorine or various other mechanisms. Since an ORP sensor measures the potential generated from the active form, versus the inactive form, they can provide a more accurate form of sanitation effectiveness.
The housing of the smart pool skimmer 100 is designed to accommodate one or more electronic sensors, which include, but are not limited to: ORP, pH, Temperature, Chlorine PPM, water level and wave interactions. In an exemplary embodiment, the electronic sensors provide feedback and information regarding pool characteristics wirelessly over the cloud through an antenna and digital radio system embedded in the microcontroller.
Additionally, the sensors can detect salt concentration, calcium, alkalinity, water current, light, motion, and sound. In one embodiment, sensors may extend from the body housing to receive and transmit acoustic signals, or water chemistry data. In some embodiments, the sensors can detect water level and wave characteristics that would indicate objects entering the pool, and the lower body is formed accordingly to allow for these sensors. These sensors include water level float switches and electronic solid state level sensors. In another embodiment, the sensors can include an accelerometer or tilt sensor to provide information about the state of the pool basket, such as the last time the pool basket was inspected or emptied.
In one exemplary embodiment, one of the sensors of the smart pool skimmer 100 is an acoustic sensor or an acoustic transmitter/receiver. In this embodiment, the acoustic sensor or transmitter/receiver can communicate with other submerged devices in the pool as an underwater data access point for access to the count. In one embodiment, the acoustic sensor or transmitter/receiver is strategically placed on the bottom or side of the pool or spa, and the acoustic sensor or transmitter/receiver transmits a signal to the smart pool skimmer 100 to indicate any acoustic changes in the pool or spa. Acoustic changes in the pool or spa can include people or objects entering or exiting the pool or spa.
In one exemplary embodiment, one of the sensors of the smart pool skimmer 100 is a solid-state water level sensor. The solid-state water level sensor determines the filter basket condition in the smart pool skimmer 100, and can also determine pool pump conditions. For example, as a skimmer basket fills with debris, water flow is restricted and gradually increases the level of water in the skimmer 100. The water level sensor can determine whether the filter basket is clogged or free of debris. Similarly, the water level sensor can detect whether the pool pump is on or off. In one embodiment, the smart pool skimmer 100 uses machine learning in order to accurately and precisely determine pool conditions based on the history of data from the sensors of the smart pool skimmer 100.
FIGS. 1C and 1D are perspective views of the top cover and bottom cover (5) of an exemplary embodiment of the smart pool skimmer 100, in accordance with certain aspects of the present disclosure, with the sensor fairing removed for illustrative purposes. In the exemplary embodiment, the smart pool skimmer 100 uses an integrated ORP/pH/temperature sensor 8 and a water level/wave sensor 9. Each of the sensors are secured and sealed to the body housing. The body housing further comprises a bottom cover that is removable with thread forming screws and sealed when installed with a weathertight gasket. The exemplary embodiment of the smart pool skimmer 100 includes ultrasonic plastic weldments for a permanent seal between the top and bottom covers. The exemplary embodiment also includes securing clip recesses 7 that allow the smart pool skimmer 100 to be secured to universal adaptor collars.
In one embodiment, the smart pool skimmer 100 has one size which allows for configurable adaptor collars to accommodate various size pool skimmers. Each of these adaptor collars have universal inner dimensions that snap fit to the smart pool skimmer 100. The outer dimensions of the adaptor rings are sized to fit the overall majority of skimmers in the market.
The integrated ORP/pH/Temp sensor 8 can additionally be replaced and/or combined as a Chlorine (PPM) or salt indicator probe as required. As described above, additional sensors can be added to the smart skimmer 100 based on design variations, sensor consolidations and general improvements in sensor technology.
In an exemplary embodiment, the smart pool skimmer 100 monitors temperature using one of the sensors. A temperature probe is integrated with the ORP/pH/Temperature Sensor 8. Data analytics using the cloud-based machine learning software will process temperature and sunlight trends to determine, but not be limited to, unwanted scenarios, such as algae and other unwanted potential biological formations in the pool. Data analytics and cloud-based machine learning are discussed in detail below.
Due to the static position of the plate, pool water level can be monitored using a water level sensor 9. In this exemplary embodiment, the sensor will be in the form of a solid-state resistance sensor. This sensor may also have the ability to detect water interactions that reflect objects entering the water. This sensor therefore may have the capability to function as a pool alarm. Through the cloud-based software of a pool monitoring system, the smart pool skimmer informs the system user of objects that have entered the pool based on requirements or settings. The sensors can be enclosed in one or more plastic tubes for protection from dirt and debris. The protective tube can be adequately vented to prevent air pockets or other scenarios which could negatively affect measurements.
In one embodiment, the smart pool skimmer 100 functions as a pool water level and/or alarm device only. This reduces the capital investment of customers by reducing electronic equipment and complexity. Various design modifications may add and remove hardware, software and sensors to satisfy customer needs.
In one embodiment, the top cover 1 and bottom cover 5 are designed with a weathertight seal. In another embodiment, a watertight seal would be provided.
In the exemplary embodiment, the top cover 1 is designed with a recessed channel for a rubberized over-mold with a chemical or mechanical bond to create a gasket 14. The bottom cover is designed with a tapered edge 15 that compresses the gasket 14 for a weathertight seal. The bottom cover 5 and top cover 1 are secured with threaded stainless steel screws.
In the exemplary embodiment, the bottom cover 5 is equipped with a micro or mini USB charging and communication port for connection to the communication unit discussed in reference to FIG. 5. The function of this port is for initial setup, charging, troubleshooting and downloading of locally stored data. Another embodiment of this design includes a waterproof reset tactile switch.
FIG. 2 is a bottom perspective view of an exemplary embodiment of the smart pool skimmer 100, in accordance with certain aspects of the present disclosure. In the exemplary embodiment, the smart pool skimmer 100 includes the integrated ORP/pH/Temperature Sensor 8, water level sensor 9 and USB charging port 10.
FIG. 3 is a bottom view of the top cover of an exemplary embodiment of the smart pool skimmer 100, in accordance with certain aspects of the present disclosure. The top cover 1 includes the electronics compartment 11 which houses two primary components: the power source (not illustrated) and primary control board (not illustrated). In one exemplary embodiment, the control board and power source are sealed with an encapsulation compound. The control board will include four LEDs 30 which will transmit light through the upward facing light pipe 4. The light pipe is bonded or insert molded into the top cover as a watertight seal.
FIG. 4 is a top view of the bottom cover 5 of an exemplary embodiment of the smart pool skimmer, in accordance with certain aspects of the present disclosure.
FIG. 5 illustrates an electronics architecture schematic of an exemplary embodiment of the smart pool skimmer, in accordance with certain aspects of the present disclosure. The solar panel 20 acts as a power source to the system and is regulated through a charge controller 22. The power source can include a rechargeable battery 24 that provides power as required in non or restricted sunlight conditions. A microcontroller 26 connects to the sensors 28, which are both digital and analog depending on their function, through sensor circuitry 32. In one exemplary embodiment, the microcontroller 26 stores data locally or sends the data to the cloud when a Wi-Fi and/or cellular connection are present. In the exemplary embodiment, the microcontroller 26 runs a real-time operating system that enables it to take advantage of low-power modes, concurrent processing, and advanced pipelining, which can allow the smart pool skimmer to run advanced models on real-time data, without disrupting observation of measurements by the sensors.
In an exemplary embodiment, the smart pool skimmer's microcontroller 26 uses a communication unit 34 to communicate with other devices, such as a mobile device or any other computing device. The communication unit can use Bluetooth, Bluetooth Low Energy (BLE), Wi-Fi, cellular or any other type of communication protocol currently available or later developed to communicate with other devices. Because the microcontroller 26 is in communication with the communication unit 34 and therefore other devices, the software and firmware of the smart pool skimmer can be upgraded, can transmit near real-time measurement information of the sensors 28, and can be reconfigured and/or recalibrated when needed.
In one exemplary embodiment, the smart pool skimmer generates power through a solar panel; however in sunlight restricted areas, the skimmer uses alternative power sources, including a rechargeable or replaceable battery 24, or hydropower via a micro-turbine. In an alternative embodiment, the micro-turbine would attach to the bottom cover 5 and utilize the water flow entering the skimmer as a source of hydropower.
In another exemplary embodiment, the smart pool skimmer can be a part of the pool monitoring system. An exemplary pool monitoring system comprises the pool skimmer as disclosed herein, a cloud-based analytics server in communication with the pool skimmer using a computer network, such as the Internet, and a user computing device with a graphical user interface for visualization of trend-based conditions of the pool water. The smart pool skimmer transmits information regarding conditions of the pool water to the server using the communication unit of the smart pool skimmer, and the cloud-based analytics server tracks the conditions of the pool water. The cloud-based analytics server, using machine learning algorithms, takes in current and historical sensor data to predict behavior of the pool chemistry, water level, and chemical reactions to alert users of the exemplary pool monitoring system of upcoming events. The development of the machine learning algorithms is performed in the cloud using big data aggregation tools that train the models of the machine learning algorithms. The data gathered from the sensors of the smart pool skimmer can easily show patterns and trends because the data reflects biological cycles such as temperature rising and falling, sunlight for a predicted time of day, and evaporation constants that correlate with temperature. Based on the data patterns and trends, highly accurate machine learning models are developed, and are sent to the user computing devices to run in an “offline” mode. The user computing devices can run machine learning algorithms using live data and can make predictions, even while offline.
In another embodiment, the user computing device of the pool monitoring system has third-party software that receives and uses the information regarding pool conditions, instead of the graphical user interface.
In yet another embodiment, because the smart pool skimmer is uniquely positioned at a boundary condition of air and water, the smart pool skimmer includes an acoustic transducer to Wi-Fi or Bluetooth thereby making the smart pool skimmer a unique instrument for communicating via Wi-Fi underwater. Because of the local processing power, the smart pool skimmer can use Fast Fourier Transforms (FFTs) and other acoustic sampling techniques that make communicating and detecting sound waves underwater easily possible at low power levels. The acoustic transducer enables the smart pool skimmer to be a central hub for processing and acoustic sensing.
