Abstract

A swimming pool management system including one or more sensors for sensing a respective parameter of parameters of a swimming pool. Such sensors may take the form of, for example, water level sensors, pH sensors, chlorine-content sensors, or sensors for determining the cleanliness or otherwise of the pool water. The sensor provides signals significant of the parameters sensed to processing means, and means controlled by the processing means adjust one or more parameters associated with the pool, for example, by controlling circulating pumps, filters, pH-adjusting devices or chlorination apparatus. The processing means may also, for example, control such devices as robotic pool cleaners, so that such a device may be activated, for example, when the pool is not occupied and when the sensors detect that pool cleaning is required, or when the sensors detect that a certain period of time has passed.

Description

DESCRIPTION OF INVENTION
Title: "Swimming Pool Management System"
THIS INVENTION relates to a swimming pool management system and it is an object of the invention to provide an improved means of maintaining a swimming pool in an appropriate condition.
According to the invention there is provided a pool management system including one or more sensors for a respective parameter or parameters of a swimming pool, said sensor providing signals significant of the parameter or parameters sensed to processing means and means controlled by said processing means for adjusting one or more parameters associated with the pool.
One sensor providing such signals to the processing means may comprise a water level sensor or depth sensor and the processing means may be programmed to control, on the basis of the signals received from said water level or depth sensor, means for adding water to the pool. In this case, the sensor may comprise, for example, a simple float which operates switches according to the level at which the float is disposed in relation to a fixed point. Alternatively or additionally, a depth sensor may be utilised, for example operating by sonar and serving to determine the depth of the pool. For example, a sonar transmitter/receiver may be located on the bottom of the pool and arranged to detect the distance from the bottom of the pool to the water surface.
In a preferred embodiment, the processing means, which preferably comprises a microprocessor, or which may be provided by, for example, a multi-tasking PC within the premises to which the swimming pool is attached, is arranged to control a plurality of devices associated with the swimming pool, such as circulating pumps, filters, pH adjusting devices, chlorination apparatus and so on and is arranged to receive signals from a variety of corresponding sensors, including water level sensors, pH sensors, chlorine-content sensors, or sensors for determining the cleanliness or otherwise of the pool water or of the walls of the pool. The processing means may also include timing means and may be arranged to compare parameters sensed at different times over an extended period, for example with a view to detecting trends which may reguire correction, or to detecting the persistence, over an extended period, of conditions likely to lead to parameter changes requiring correction. For example, the apparatus may be arranged to detect periods of high ambient temperature or insolation which may favour growth of microorganisms.
The processing means may also, for example, control such devices as robotic pool cleaners, so that such a device may be activated, for example, when the pool is not occupied and when the sensors detect that pool cleaning is required or when the sensors detect that a period of time has passed during which conditions have been such as to encourage algae growth, etc.
The processing means may also be arranged to give visual or audible warnings associated with the pool, for example, indicative of such conditions as blocked filters, malfunctioning pumps or motors and so on. In the last- noted scenario, the processing means preferably is also arranged to switch off malfunctioning devices such as circulation pumps before further damage is caused to these.

Claims

1. A swimming pool management system including a sensor for water level or other parameter, said sensor providing signals significant of the parameter sensed to processing means, and means controlled by said processing means for adjusting one or more parameters associated with the pool.
2. A pool management system according to claim 1, including, as such a sensor, a depth sensor for assessing the depth of the pool .
3. A pool management system according to claim 2 wherein said depth sensor comprises a sonar device.
4. A pool management system according to any preceding claim including, as such a sensor, a means for sensing the state, for example the operating load, of a circulating or filter pump associated with the pool and wherein said processing means can control said pump in accordance with the output of said sensor.
5. A pool management system according to any preceding claim including, as such a sensor, means for sensing the level of soiling of the water in the pool, said processing means being arranged to activate a filter pump or other pool cleaning means in response to the level of soiling sensed.
6. A pool management system according to any preceding claim wherein said processing means is arranged to operate a robotic pool cleaner.
7. A pool management system according to any preceding claim including, as such a sensor, a sensor for sensing water level in the pool and wherein said processing means is arranged to control a valve for admitting water to the pool in accordance with the level sensed, to maintain a predetermined level.
8. A pool management system according to any preceding claim including, as such a sensor, means for sensing the chemical balance of the water in the pool and for passing corresponding signals to said processing means and wherein said processing means is arranged to control means for adding chemical to the water to adjust such balance as necessary.
9. Any novel feature or combination of features described herein.
