The present invention relates generally to pool monitoring hardware, and more specifically relates to an internet-connected water-testing device, configured to provide easy and expedient access to water quality monitoring features of a pool or hot tub from any location via a smartphone or other internet-connected device. Also, the present invention incorporates weather station functionality that provides the user weather data specific to the user's residence and pool environment from any location via a smartphone or other internet-connected device.
A swimming pool and/or hot tub is often at the forefront of many dream homes of Americans, and are popular in countless homes and communities all over the world. They provide cool and relaxing places for individuals to de-stress and unwind, and are a delight in the summertime. Unfortunately, much to the dismay of many pool owners, pool maintenance is not usually a fun task. Keeping a swimming pool or hot tub requires weekly (occasionally biweekly) water testing, pump and filter maintenance, water skimming, chemical mixing, and adding acids, chlorine and other chemicals to the water. Without maintenance such as this, pools can quickly become unsanitary and even unsafe for swimmers. Algae build up can quickly overtake a pool in warm climates, causing the owner to ‘shock’ and clean the pool over a period of time. This often requires timely addition of chemicals, which can easily be forgotten. Without consistent maintenance, pools can quickly become unusable. To some, the maintenance is cumbersome and droll, and therefore, the pool can become neglected, and the maintenance duty schedule forgotten.
Even more, there is a need for a convenient and more accurate pool or hot tub monitor than is currently on the market. For example, unless various readings can be interpolated to give an overall picture of that which is taking place in a pool or hot tub, the single readings alone might not trip an alert that something is awry in a pool or hot tub. In other words, there is a need for a pool or hot tub monitor that can piece readings together to alert when a few readings might not cause alarm if they are not correlated together.
Thus, there is a need for a smart pool maintenance device and system configured to interface with the mobile, or other internet-connected devices of the user, and alert him or her with real-time data relating to the overall quality of the water and proximal environmental conditions. Such a device would preferably have a buoy component configured to float in the swimming pool water, and a gateway component. The buoy is equipped with sensors to attain pool environmental data, and convey the data wirelessly via wireless radio technology, to the gateway unit. The data is stored on cloud-based servers in communication with the internet, providing for easy access to the data from any internet enabled device. Such a device will promote and safeguard the healthy and safe use of swimming pools and spas.
The swimming pool is a complex environment that requires constant care in order to be used safely, healthily, at a reduced cost and with minimal impact to the environment. The present invention implements all the main activities required to empower the pool owner with knowledge and timely information for maintaining a fun and relaxing pool environment. The present invention provides real time measurement data of key water quality parameters as well as other environmental parameters that affect the water quality and pool experience. Additionally, it measures other parameters that might be harmful for the pool user.
A buoy collects and conveys information to a gateway unit that, by using intelligent algorithms, is capable of informing pool users and technicians about pool conditions in real time. By further combining data from a multitude of swimming pools in nearby regions, a set of algorithms improves the recommendations for better achieving water chemistry balance.
The present invention is a wireless pool monitoring and water-testing device housed within a floating buoy, and a wireless, internet-enabled gateway. The present invention employs two MCUs (Micro Controller Unit, one in the buoy and one in the gateway), one radio unit in the buoy and another one in the gateway as well as one Wi-Fi module and several measurement modules. The present invention employs cloud storage as a means to store measurement data and pool history over time. The present invention is configured to communicate via the gateway to an access point for internet connectivity. The radio module of the present invention ensures the communication of data from the buoy to the gateway and vice-versa. The gateway transmits the measurements (quantitative data) performed by the present invention to the cloud storage. The gateway can also charge the buoy device of the present invention, as well as other devices compatible with the induction-charging platform employed by (and provided via) the gateway of the present invention. It should be understood that the present invention can obtain several measurements, and then obtain a correlation to recommend whether a pool is safe and/or comfortable for use.
The two primary functions of the present invention; water quality monitoring & weather station functionality combined in a single system provides the user all necessary water and environmental data to assist in maintaining a healthy and safe pool and home environment.
The present invention will be better understood with reference to the appended drawing sheets, wherein:
The present invention is a swimming pool monitoring and management system that employs a buoy (10) and a gateway (40). The buoy (10) is in communication with the gateway (40) via a wireless radio connection established via a high performance low power radio on board the buoy (10) and the gateway (40). The buoy (10) is equipped with a sensor array (20) that is configured to accurately detect and quantitatively measure the conditions of the environment. The sensor array (20) is preferably equipped with at least one temperature sensor, a PH reader, an ORP reader, and an impact detector (conveyed via at least one accelerometer).
The measurements performed by the various sensors of the sensor array (20) of the buoy (10) device of the present invention in the pool are chosen from the following group:
The buoy of the present invention is also configured to perform the following system monitoring measurements:
The measurements performed by the various sensors of the gateway (gateway sensors (60)) are chosen from the following group:
The gateway (40) is configured to receive all data measured by the buoy (10), and will transmit the data to cloud storage services and to mobile platforms. The gateway (40) is configured with an induction charging mechanism (30) configured to be used to charge the buoy device when the battery level of the buoy (10) goes below a certain threshold.
The gateway (40) also houses the alarm speaker that is triggered to sound when the pool is armed for security, and a person or a large object falls into the pool. The present invention, when armed, detects the presence of a large object or person falling into the pool, via an algorithm that analyzes, in the time and frequency domain, the data collected by the accelerometer and ultrasonic sensors disposed within the sensor array (20) of the buoy (10).
The gateway (40) can also monitor the environment inside in the house, where the gateway (40) is preferably located. The gateway (40) of the present invention also acts as a hub for other devices that can be integrated in the system of the present invention.
The process of use of the present invention, as depicted in
Alternate embodiments of the present invention include variations on the gateway (40), which may be configured to interface with other devices. Therefore, the present invention also allows the integration of other devices via the gateway (40). It is envisioned that the software of the gateway (40) allows for the control of other devices related to home automation. As possible examples, is envisioned that the gateway (40) of the present invention may remotely control the pool pumps, the water heating unit, communicate with outdoor weather stations, and to other alarms systems. The hardware design of the gateway (40) of the present invention allows for the integration of additional sensors, probes and controllers, each of which are preferably disposed outside the buoy (10). The integration of these peripherals is done by wireless connectivity with the gateway (40).
The present invention manages to integrate in the same compact package all the key sensors to get a very detailed picture of the pool environment. By placing all the sensors (sensor array (20)) in the buoy (10), the present invention is capable of informing the pool user about the exact conditions that will be experienced at the pool. By using a combination of the measurements made by the sensor array (20) of the buoy (10) with accelerometer data, and UV/light, the system is able to intelligently weigh, modify and discard all but the relevant data. The gateway (40) utilizes temperature and humidity measurements to compensate the air quality measurements. For accuracy, the gateway (40) is designed with two generous air intake vents, and the PCB (Processor Control Board) has been adjusted to place possible interfering sources away from the sensor array (20). The gateway (40) also uses an intelligent algorithm to compensate temperature skewing during wireless charging activities.
It should be understood that the gateway (40) preferably acts as the system brain, remotely instructing the buoy (10) to perform measurements at the correct time so that it can preserve its battery life. It is crucial that the battery longevity is such that the user does not get bothered constantly to recharge it.
It is envisioned that the buoy (10) will preferably be equipped with an add-on propulsion system to enable the buoy (10) to be used for enhanced fun activities, to automatically perform measurements along several pool locations, and to engage in basic cleaning functionalities. The control of the propulsion system can be either executed manually through the software installed on mobile devices in communication with the buoy (10), or automatically through the algorithms implemented in the gateway (40).
The buoy (10) is preferably equipped with an integrated speaker that is used for basic communication with the user during setup and troubleshooting activities. Additionally, the buoy (10) is equipped with an LED light to complement the previous functions.
The user will be notified when the battery of the buoy (10) runs below a given threshold, and also if the communication with the buoy (10) is interrupted.
The gateway (40) is preferably also equipped with an LED that indicates the correct operation of the system of the present invention. In case of any abnormal event, the LED will flash to warn the user. In parallel, all the detailed information about system malfunctions is conveyed to the mobile devices in communication with the system of the present invention.
In some embodiments of the present invention, the buoy (10) can be upgraded to be charged through a solar panel attachment, coupled together with the propulsion system which can also be used to dispense chemicals throughout the pool.
