Description

Management of a swimming pool park

The invention relates to a method of managing a pool of individual pools. It also relates to a means of local control of an individual pool and a management server of a swimming pool park. Finally, it concerns a management system of a swimming pool park.

In order to manage the quality of the water of a swimming pool, it is known to measure certain quantities representing this quality, such as its pH for example, and to intervene if these quantities come out of desired ranges, injecting for example a product of acid treatment if the pH exceeds a maximum allowed. This management of a pool is more or less automatically, in any case in a non-optimized way, resulting in failures. These are manifested by the periodic obtaining of turbid water, in a so-called "degraded" state, whose quality thus does not reach the desired objectives, and by obtaining a consumption of resources (water ( used by filtration), products, energy) as well as a consumption of non-optimal pool water treatment products. Numerous physicochemical or bacteriological factors can be the cause of the appearance of a degraded state of the water of a swimming pool, and several types of such states can occur, which makes it very difficult to maintain the quality of the water in a predefined range, or even the prevention of its passage into a degraded state.

In addition, when the owner of an individual pool detects an abnormal situation that exceeds his competence, he calls on a pool maintenance professional. This call is often too late and the professional has too little information to schedule a quick and effective intervention. There is therefore a need to improve the management of a swimming pool. More specifically, there is a need to optimize the management of the water quality of a swimming pool, consisting of the definition of an optimal compromise to achieve an increased water quality for energy consumption. and minimized treatment products.

For this purpose, the invention is based on a method of managing a swimming pool park, characterized in that it comprises the following steps:

measuring or estimating at least one datum representing the quality of the water of each pool of the park by its own means of local control,

transmission by the local control means of this at least one datum to a remote server of a management center via a communication network.

The invention is more precisely defined by the claims.

These objects, features and advantages of the present invention will be set forth in detail in the following description of a particular embodiment made in a non-limiting manner in relation to the appended figures among which:

Figure 1 schematically shows a management system of a pool of pools according to one embodiment of the invention.

FIG. 2 diagrammatically represents a means of local control of a swimming pool according to the embodiment of the invention.

FIG. 3 diagrammatically represents a means for regulating the local control means of a swimming pool according to the embodiment of the invention. FIG. 4 shows in another form a device for managing an individual swimming pool incorporating a local control means according to the embodiment of the invention.

The concept of the invention consists in connecting several individual pools to a management center, which exchanges parameters and data relating to each pool with a means of local control of the water of each pool. This approach allows a centralized and automated pool supervision, which can be proposed by a professional, which allows to improve the monitoring and management of each individual swimming pool of a pool park, regardless of the distance from these pools individual, which can for example be separated by more than one kilometer or more than ten kilometers, without limit on their distance. This approach provides a significant improvement over the semi-automatic management of each isolated pool, under the sole supervision of its owner often not very expert in this area.

FIG. 1 represents a swimming pool park 10 according to the invention, in which each swimming pool is linked by a communication network 20 with a management center 30 of this swimming pool park, which may include a central remote server equipped with software management of the swimming pool park, as well as monitoring equipment 40 and 40 'and an information base 50, which may consist of a weather server for example.

The pool park 10 includes four pools 11, 13, 15, 17, type discovery private pool, installed in a primary or secondary residence, or a hotel, a campsite, a sports center, leisure, fitness, etc. Each pool comprises respectively a local control means 21, 23, 25, 27 of the water quality, provided with analysis means and processing means, the operation of which will be described later. To simplify and to illustrate the principle of the invention, the park shown comprises only four pools but the invention can naturally be applied to any number of pools, greater than or equal to two. Each local control means 21, 23, 25, 27 comprises signaling means, respectively 121, 123, 125, 127.

Pools and control means can be structurally different from one pool to another. Thus, the swimming pool park 10 constitutes a set of heterogeneous elements. However, all the control means 21, 23, 25, 27 are connected to the same communication network 20, for example and preferably an Internet-type public network.

These control means 21, 23, 25, 27 are connected to a management center 30 via this communication network 20. The definition of the pool park results in particular from individual subscriptions to the management center 30 and is translated at least by the presence of identifiers of each local control means or each pool in a memory

31 of the management center 30. Conversely, an identifier of the management center 30 is known from each local control means 21, 23, 25, 27.

In addition to an identifier of each local control means 21, 23, 25, 27 of the pools 11, 13, 15, 17 of the pool park 10, the management center 30 has in memory precise data on the location of the pool, its dimensional characteristics, the characteristics of the local control means and, possibly, it also has historical data on the physico-chemical or bacteriological state of the water and / or on maintenance operations. A first tracking device 40 is also connected to the communication network 20. This tracking equipment is used by a first professional pool maintenance, called "maintenance agent" or "pool" or even an owner interested and supervising his pool, that of his neighbors, his family, having entered into a maintenance contract with some of the pool owners of the park, for example those of the first pool 11 and the fourth pool 17.

Similarly, a second tracking equipment 40 'is used by a second pool maintenance professional who has entered into a maintenance contract with the owners of the second pool 13 and the third pool 15.

Each tracking device 40, 40 'is known both from the management center 30 and the control means 21 and 27, 23 and 25 of the subset concerned, at least by sharing identifiers.

A tracking device comprises a human-machine interface and has in memory, like the management center 30, precise data on the location of the pool, its dimensional characteristics, the characteristics of the local control means and possibly also has historical data on the physico-chemical or bacteriological state of the water and / or on maintenance operations. These data are preferably recorded by the professional in his monitoring equipment and then communicated to the management center.

Due to the possibility of bidirectional communication on the communication network 20 and the presence of appropriate hardware and software means in the control means 21, 23, 25, 27 of the pools, in the management center 30 and in the equipment of tracking 40, 40 ', it is possible from the management center 30 or from a tracking device 40, 40' to have access to the measured data by a means of local control 21, 23, 25, 27 and / or to cause remote processing operations on this control means. A local control means may also directly warn the corresponding tracking equipment 40, 40 'and / or the management center 30 during a serious event, and in particular when crossing predetermined thresholds which may lead, for example, to a passage in a degraded state of the water of the corresponding swimming pool.

As a remark, the tracking equipment and the management center can in fact be confused, their functions being fulfilled in such a case by the same remote device as a remote server. For example, in a pool park with relatively few individual pools, only one installer manages the pool park. Its monitoring equipment then becomes "management center" within the meaning of the invention, and it contains an algorithm able to manage the pools of the park. Thus, to simplify the rest of the description, it will no longer be referred to a tracking device and the term management center will be interpreted in the broad sense to include any remote device management, monitoring and pool supervision.

Thus, the centralized management system of a swimming pool park according to the invention allows the implementation of the following step of a pool park management method:

- Transmission by a local control means of a pool of at least one measure or data representing the water quality of the pool, through a means of communication, to a remote server of the management center.

In particular, the method of managing a swimming pool park of the invention comprises transmitting the following measurements to the central server of the management center 30: - measuring the temperature of the water;

- pH measurement;

- measurement of chlorine or equivalent product, such as salt or bromine or ozone or active oxygen or level of UV production, of disinfectant electrolysis such as the production of chlorine by salt electrolysis, the function of which is the treatment of water .

In addition, the management center 30 can also be informed of the water filtering periods provided for each pool of the park, remember these periods, receive any modification that would be made locally at the pool, by means of local control of water for example. It may comprise a step of measuring the state of the filtration, for example by pressure or flow. These measurements or data significant for the management of the water quality of a swimming pool may be transmitted to the management center periodically, according to a period programmed in the local control means of each pool, this period being able to be modified locally or on request from the management center. As a variant, these measurements or data may be transmitted on request from the management center, or transmitted by the local control means following a particular situation, as a particular measurement, for example a turbid water situation. These different measurements and data gathered on the remote server of the pool park can be presented to a pool / supervisor by a human machine interface allowing the visualization of all these data for each pool, in a single table for example. The values coming out of predefined ranges can be highlighted, for example by a particular color code, in order to immediately visualize any abnormal situation, for example corresponding to a cloudy or cloudy water becomes cloudy. Alarms can be triggered automatically for these measurements leaving predefined ranges. A supervisor can initiate actions remotely to act on the various means of pool control to improve their water management, for example by triggering a filtration of water, adding a treatment product. These actions can be automatic, by transmitting a command from the remote server by means of local control of a pool, which implements the appropriate actions. Thus, the management method of a swimming pool park according to the invention also allows a local control means of a pool that detects the appearance of a degraded state of the pool water to immediately transmit the information at the management center. It further comprises an automatic processing step following the degraded state of the pool water, implemented by a control of the management center and / or by a pre-programmed regulation in the control means.

According to the embodiment of the invention, the pool park management method implemented by the software means of the management center also comprises a method for determining the endangered pools, that is to say the pool water is likely to pass into a degraded state. This process uses a risk criterion. It may also include the use of an expert system, also incorporating terrain data and / or historical data. Some pools can be known to have a greater sensitivity due to a particular constitution or because of the control means used or without any particular explanation but simply because of historical incidents. The predetermined threshold of risk can be modulated according to this sensitivity specific to each pool and acquired for example automatically using the expert system. According to an advantageous embodiment of the invention, the method for determining endangered pools takes into account the degraded state of neighboring pools and / or the like to deduce a probability that this change of state may occur on another pool of the park. This approach is particularly relevant when the change in the degraded state of the pool water is caused by pollution by acid rain or other local weather phenomenon, which can contaminate in the same way any pool placed in the same conditions. In the case of the threat detection on a certain pool, an alert message is displayed on a screen of the management center and / or on a screen of the local control means of the pool. In both cases, a LED, TV, tablet type iPad, LCD or OLED display can be used.

The local control means of the pool concerned then implements appropriate preventive treatment. Preventive treatment can also be implemented remotely by the management center. In both cases, the local control means of the threatened pool receives a preventive treatment command via the communication network 20.

An option of the local control means allows the owner to accept or not a direct activation of the local control means by the management center.

Preventive or curative treatment may consist of the injection of certain treatment products into the pool, the closing of a mobile screen protecting the outdoor pool, or any other modification of the state of the pool. For this purpose, the management center 30 can intervene on the local control means of a swimming pool by modifying setpoint values and / or maximum values and / or minimum values of magnitudes. representing the quality of water such as pH, chlorine or salt or bromine or ozone or active oxygen or level of UV production, disinfectant by electrolysis (example: chlorine production by salt electrolysis), modifying the ranges of these set values and / or maximum values and / or minimum values of quantities representing the quality of the water, by modifying the filtration ranges of the pool water, by adding treatment products in the water of the pool the pool or in a suitable tank. According to an advantageous embodiment, all these commands and interventions of the management center on a given pool are recorded on the memory 31 of the management center and / or on a memory of the local control means. This keeps the history of the management of each pool.

The messages may be sent by the management center 30 in the form of alphanumeric strings. Preferably, at least part of the message is stored in a memory of the control means. For example, the content of a SIGN signal is fully pre-recorded in the local control means 21, as for example the preventive processing algorithm. The owner simply validates the start of the preventive treatment by pressing a key. In the second alert message MSG2, the management center then simply sends a code causing in particular the display of the alert signal. An example of an alert signal, pre-register partially, is as follows:

"Alert" [Type_Menace]

"- Treatment" [Type_Treatment] "needed as soon as possible. Press validation key » In this example, the management center simply sends to the local control means the coded content of the variables [Type_Menace] and [Type_Treatment]. The local control means contains in memory the different alphanumeric strings corresponding to the different codes and displays the message corresponding to the code received.

Examples of alphanumeric values for [Type_Menace] = "Acid Rain" or "Sand Wind" or "Pollution" etc.

Examples of alphanumeric values for [Type_Treatment] = "preventative" or "Chlorine" or "Chlorine and pH" or "UV" etc.

The hardware and software resources of the management center allowing the application of the management method described above also allow the storage of a correspondence table between identifiers of each control means,

The invention is independent of the nature of the communication network. This can be homogeneous or heterogeneous. For example, in the first case, all communications are provided over the Internet or all communications are provided by sending SMS, while in the second case some communications can be provided by the Internet while other communications can be provided by sending SMS. It is also possible to send a message directly to the owner of a pool by SMS digital voice mail or voice messages.

The local control means 21 of a pool 11 will now be explained.

Figure 2 shows an individual pool installation using the method according to the invention. The installation comprises a basin 11 and a local control means 21 comprising means for analyzing and regulation 3 of the quality of the water in the pool and connected to the pool by an extraction pipe 4 and a delivery pipe 5.

The local control means 21 also comprises supervisory means 6 communicating with the regulating means 3 by a first connecting means 7, such as a set line, and by a second connecting means 8, such as a line regulatory information.

The first connecting means and the second connecting means are advantageously made by bidirectional radiofrequency communication if the regulation means and the supervision means are physically distant by several meters.

The supervisory means 6 communicate with the remote server of the management center 30, common to several installations and dedicated to monitoring the park of individual swimming pools, as explained previously, by the communication means 20, such as a network. Internet. Alternatively, the installation may be linked to another remote server, not shown in Figure 2, which may be a weather server.

The local control means 21 comprises four actuators connected to the water circulation circuit going from the extraction pipe 4 to the discharge pipe 5, represented in FIG. 3. A first actuator 12 is for example a metering pump, allowing the injection of chlorinated products. A second actuator 16 is for example an electrolysis device. A third actuator 18 is for example an ozonator. Alternatively, the third actuator is an ultraviolet light device. The fourth actuator 24 is a motor acting on a circulation pump. The water coming from the extraction pipe is thus pushed back into the basin by the discharge pipe. Alternatively, others actuators not shown can be used to interact with a heating device, valves (multi-channel or single).

The actuators are powered by a power supply line 25, for example from the AC mains, provided with means of voltage step-downs and / or differential protection not shown. The actuators 12, 16, 18, 24 are controlled by control lines, respectively referenced 120, 160, 180, 240 for the actuators. The control lines come from a microcontroller 35. A physico-chemical sensor assembly 36 comprises a first probe 361, for example a pH probe, a second probe 362, for example an optical probe or a chlorine probe, and a third probe 363, for example a water temperature probe. Other probes can also be used, for example for the measurement of flow and / or pressure of water or for the measurement of bacterial concentrations. These probes are connected to the microcontroller by measurement lines, respectively referenced 364 to 366 and perform the function of measurements of quantities representing the quality of the water of the basin 11 and form a means for analyzing the quality of the water.

The microcontroller 35 executes a control program of the multi-variable servo type capable of satisfying a water quality criterion by driving the actuators using the control lines from data collected on the measurement lines. Any technique in the automatic domain can be used in the control program, including expert system rules or fuzzy logic. In a very simple case of single-variable regulation, a PID (Proportional Integral Derivative) type of servocontrol is used and the quality criterion is the setpoint of the PID servocontrol. There is therefore a set value of the quality criterion, also called objective or target value, and a real value, measured or calculated from measurements obtained. on the measurement lines. The quality criterion is satisfied if the actual value differs very little from the set value, for example to less than 5% or even less than 2%. Beyond a certain difference with the set point, the quality of the water is considered to be degraded.

The supervision means 6 and the regulation means 3 are represented as physically different. This is indeed the case if a first control device comprises only the supervision means, while a control device comprises only the control means. Alternatively, the supervisory means but also a part of the regulation means, and in particular the microcontroller 35, are grouped together to limit the hardware and software hardware resources required by the supervisory and control means in a common logic and calculation unit. not shown. In all cases, these two functions of regulation and supervision participate in the local control means 21 of the pool 11.

Thus, the local control means 21 of the pool 11 implements a method for controlling the water quality of an individual swimming pool comprising control means controlling actuators acting on physicochemical parameters of the water to satisfy a water quality criterion and comprising supervision means limiting the action of the actuators by operating limits set at different operating parameters or data, mainly the data representing the quality of the pool water.

The operating parameter is for example the time and its limits then correspond to at least one authorized time slot. Another operating parameter is for example the daily quantity, or hourly, or for a certain time range, quantity of products. chlorinated, of which a maximum authorized quantity is predefined. Equivalently, a maximum quantity limit of any treatment product can be predefined. These limits are not exceeded, even if the regulation provided by the local control means 21 does not achieve the given instruction. In the latter case, the anomaly can come from a measurement error, for example following a failure of a measuring probe, and the predefined limits make it possible to avoid unnecessarily and sometimes dangerously spilling a large quantity of product treating . Otherwise, the local control means of the pool can move to another mode of operation more suitable, with other maximum values for the operating parameters, which allows to achieve the desired water quality.

Thus, several modes of water treatment of the pool may be provided, in which at least some of these operating data operating limits are different: for example, a first mode is more limited and more economical in energy expenditure and / or in treatment products that a second mode less limited. Following the receipt of information, the local control means 21 of the pool can automatically cause the passage in the second mode of treatment although the water quality criterion is satisfied in the first mode of treatment, in order to anticipate a future evolution of the water quality of the pool. The operating limits are determined by an installer or are transmitted remotely by the management center 30. These limits can be automatically determined according to the use of a swimming pool, taking into account the number of bathers, by a sensor. presence to calculate its use. Indeed, the presence of swimmers plays a large role in the need for treatment products: bacterial inputs, sweating, mixing water. It is therefore particularly advantageous to anticipate a change of mode according to information related to the presence of at least one swimmer, and preferably according to information of the number of swimmers, this number being at least estimated. A very low use corresponds for example to less than one user for 40 cubic meters of basin. Lack of use or very low use can also be characterized by a state of total rest (or near-rest) of water in the basin. Normal use corresponds, for example, to a user density that is greater than the previous case but remains less than one user per 10 cubic meters of pool.

These density thresholds, given as an indication, can be parameterized according to the temperature of the water, cold water being more tolerant to a large number of users, and / or depending on the agitation of the water. caused by users. They can also integrate historical data, and / or be determined by an expert system housed in the management center 30.

According to another advantageous step of the pool management method, the information of a weather server is taken into account to determine the mode of operation of the local control means of the pool. For example, information transmitted to the control means, such as a significant risk of storm, for example, causes a change of mode, for example a transition from the average processing mode to the strong processing mode. Indeed, a stormy weather easily causes a change in the state of water by promoting bacterial proliferation. This meteorological information can be transmitted directly by a specific weather server 50 or by the server of the management center 30 of a swimming pool park which also centralizes the meteorological data management. FIG. 4 shows in another form a device for managing an individual swimming pool incorporating a local control means according to the invention. For this, the management device 1 of the pool, essentially comprising the pool local control means explained above, comprises the sensors or probes 361 -363 mentioned above, which measure certain quantities representing the quality of the water, as per example its pH, its content of chlorine or salt, its temperature, or even complementary sensors 367 measuring quantities of the external environment, such as the temperature of the air. Note that some of these quantities may alternatively be estimated by software and not measured. These probes communicate with a central unit 34, possibly via an intermediate box 32 provided with a wireless communication means with the central unit 34, which comprises hardware and / or software means, comprising, for example, the microcontroller 35, to implement the regulation of the water quality values as explained above. Note, the intermediate housing 32 may further perform certain functions such as sampling, standby, etc., to optimize its performance and autonomy.

The central unit 34 controls the actuators, pumps and other mechanical means to initiate actions consisting for example of a recirculation of the water through a filter 33, or the injection of treatment products of acid type, chlorine , bromine, ozone, active oxygen or in production of UV, disinfectant electrolysis such as chlorine production by salt electrolysis. In this way, the central unit 34 can automatically maintain the quality of the water at a chosen level with optimized consumption. The principle described above illustrates the normal operation of the local control means of a swimming pool, which we will call "mode of operation" thereafter. In this operating mode, the management of the pool is automatic. However, a user retains limited access to certain setpoint settings, in order to adapt the behavior of the pool to its particular use. This interaction of the user with the local control means of the pool is predefined and authorized by the mode of operation of the local control means of the pool. This interaction of the user on the local control means of the swimming pool can be done by means of a remote control 37, which communicates advantageously by a wireless communication means 38 with the central unit 34, which allows to dispose in the immediate vicinity of the pool, while the central unit 34 is in a closed annex. Finally, the swimming pool management device is connected by the communication network 20 to a remote central server of a management center 30, which may be a simple computer. For this, the local pool control means 39 is locally connected to the Internet, either by a wired connection via a modem, or by a contactless connection type wifi.

It has been described that the local control means of managing a pool uses many parameters. A technical problem arises during the initialization of these parameters, during its installation and first start-up or during a subsequent reset. Such input of parameters and settings can be long and tedious. Advantageously, different "standard" models of pools are provided, for which the corresponding values of the parameters are stored in a memory of the central server and / or in a memory of a portable object such as a USB key, a memory card, RFID. Thus, when there is a need for initialization, an intervention more than to connect its portable object by means of local control of the swimming pool, by indicating the corresponding swimming pool model or by choosing the portable object corresponding to this model, and all the predefined and prerecorded initialization values for this model of pool are automatically transmitted by means of local control. The installer only has to make the final necessary adjustments if the model chosen is not suitable for the particular pool. This results in a significant gain in intervention time, while greatly reducing the risk of error.

On the other hand, the management center 30 of the swimming pool park implements a step of automatic detection of a certain number of maintenance operations or more generally of necessary interventions on certain pools of the park, which require the movement of pools. a maintenance agent. It can then advantageously favor the realization of these operations by the following actions:

- presentation on a screen by a man-machine interface of all the pools requiring an intervention, distributed on a geographical map: this allows the maintenance agent to have an immediate global geographical vision of the necessary interventions and to facilitate the organization of his maintenance tour;

- presentation on a screen by a man-machine interface of all or part of the data representing the past maintenance operations stored for a given pool;

- The central server can even include a maintenance tour optimization software, offering an optimal tour for each maintenance agent, taking into account for example the geographical location of the pools concerned, the nature of the operations of necessary maintenance, qualification and availability of each maintenance agent ...

The management center can also include a management software of its own organization, performing certain calculations of the quality of its interventions by taking into account the response time from the moment of the detection of the need for maintenance, the time intervention and the efficiency of the operations carried out. It is also possible to perform these statistics by maintenance agent to assess the individual performance of each of them, to provide relevant training, more generally to effectively assist the management of Human Resources Pool.

In addition, centralized management of a pool of pools provides additional opportunities for intelligent management of critical resources, such as electricity, water and even treatment products. Indeed, in the event of a shortage or threat of a shortage of a certain resource in a certain territory, the management center may provide for an emergency shutdown mode, or even a low consumption mode, of the entire park or part of the park's pools located in the area concerned, thereby saving a significant amount of electricity. In fact, the overall electricity consumption of individual pools in a given territory represents a significant total. This emergency mode triggered by the management center 30 is automatic and priority over local commands that would be performed by the local control means of a pool, or by its user or a maintenance agent. This principle applies in a similar way to the management of water or the management of any other resource used by an individual pool. When the situation of shortage or threat of shortage is removed, the management center puts the pool park in its operating mode usual. In a symmetrical way, there may be certain situations where the electricity consumption is too low compared to the production in a given territory: in such a situation of opposite urgency, the management center may force the pools of the park concerned to pass emergency in a mode of operation with high power consumption.
