The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise. In the present application, the term "comprises" or "having ", etc. is intended to specify that there is a feature, step, operation, element, part or combination thereof described in the specification, , &Quot; an ", " an ", " an "

Unless defined otherwise, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Terms such as those defined in commonly used dictionaries are to be interpreted as having a meaning consistent with the contextual meaning of the related art and are to be interpreted as either ideal or overly formal in the sense of the present application Do not.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a configuration diagram of a swimming pool management system that schematically shows a swimming pool management system according to the present invention. 1, a pool management system 100 according to the present invention includes a swimming pool water tank 1, a water supply unit 2, a balancing tank 3, an aggregate transfer unit 4, an ozone generator 5, A filter 7, a heat exchanger 8, a chemical injector 9, a water quality measuring sensor 10, a control unit 11, a temperature measuring sensor 12 and a chlorine generator 13.

Water supplied from the outside through the water supply device 2 flows into the balancing tank 3 and then supplied to the pool water tank 1 through various pipes and valves. Various piping and valves (not shown) installed in the pool can be arranged in an appropriate quantity and structure as required.

As described above, the water contained in the pool water tank 1 is contaminated much during use and water temperature is generated. Therefore, the water quality and the water temperature are measured using the water quality sensor 10 and / or the temperature sensor 12 . The flocculant feeder 4, the filter 7, the chemical feeder 9, the ozone generator 5, the mixer 6 and the heat exchanger 8 are means for controlling water quality and water temperature.

Hereinafter, the path along which the water is circulated in the pool will be described in more detail.

The water supply device (2) means piping, pump, valve and the like for introducing tap water as a means for introducing tap water from the outside. The water introduced through the water supply device 2 flows into the balancing tank 3. Not only the water flowing through the water supply device 2 but also the water overflowing from the swimming pool water tank 1 during the use of the swimming pool are introduced into the balancing tank 3 and the water contained in the swimming pool water tank 1 is replaced or circulated In the course of the process, intentionally drained water can also be introduced.

The water flowing out of the balancing tank 3 is supplied to the mixer 6. The mixer 6 is for mixing the ozone generated in the ozone generator 5 with the incoming water. The ozone generator 5 generates ozone (O 3 ) for sterilizing water. The water generated in the ozone generator 5 is transferred to the mixer 6, This mixture results in sterilization. The water flowing out of the mixer 6 is then supplied to the swimming pool water tank 1 after passing through the filter 7 and entering a purified water,

The water quality measurement sensor 10 for measuring the water quality measures a water quality by sampling a part of water during circulation of water in the swimming pool. Sampling can be carried out by installing a branch piping suitable for the circulation path of the water. It is preferable that the water used for the water quality measurement is sampled in a section between the balancing tank 3 and the mixer 6. [ If water is sampled in the interval between the balancing tank 3 and the mixer 6 and the water quality is grasped, the water quality of the water contained in the pool water tank 1 at the sampling time can be more accurately grasped.

(Not shown) may be further provided between the balancing tank 3 and the mixer 6. House mosquitoes primarily purify water by removing relatively large contaminants such as yarn from hair or swimwear. Sampling of the water for the water quality measurement may be performed on the water that has passed through the house mosquito or on the water that has flowed into the house mosquito. However, sampling the water quality before going through the house mosquito has the advantage of being able to more accurately grasp the quality of the water in the swimming pool water tank. In particular, when the flocculant is applied and then filtered, the residual chlorine is sampled after the adsorption of the residual chlorine. Therefore, it is difficult to grasp the accurate water quality. Therefore, in order to obtain accurate water quality, the water is preferably sampled before passing through the mixer Do.

The water quality measurement sensor 10 measures the water quality of the sampled water, and is used to measure residual chlorine concentration, hydrogen ion concentration and turbidity in water, and a sensor capable of measuring additional characteristics as needed can be used. The water quality measuring sensor 10 outputs an electric signal corresponding to the detected residual chlorine concentration, hydrogen ion concentration, and turbidity level. In this case, the type of the electric signal to be output may be an analog signal. The electric signal outputted from the water quality measurement sensor 10 is transmitted to the control unit 11. The electric signal of the analog form outputted from the water quality measurement sensor 10 is converted into a digital signal by the analog-digital converter included in the control unit 11. [

The flocculant is introduced into the water flowing out of the balancing tank 3 by the flocculation agent 4. When the water flowing out of the balancing tank 3 passes through the house mosquito, the flocculant can be administered to the water passed through the house mosquito. The flocculant coagulates the small contaminants to increase the size of the contaminants, and the contaminants that have agglomerated and increased in size by the flocculant applied in the flocculant solution 4 are then filtered and removed by the filter 7. The water into which the coagulant is introduced is then transferred to the mixer (6). It is more preferable that the water for grasping the water quality is sampled before the coagulant is administered. This is because after the coagulant has been administered, the current water quality of the pool can not be accurately determined.

The temperature measurement sensor 12 is for monitoring the temperature of the water contained in the pool water tank 1 and outputs an electric signal corresponding to the detected temperature level. In this case, the type of the electric signal to be output may be an analog signal. 1 shows a case in which one temperature measurement sensor 12 is installed in the swimming pool water tank 1 but a plurality of temperature measurement sensors 12 are provided at an appropriate distance And the depth at which the temperature measurement sensor 12 is installed can be adjusted in various ways. The electric signal output from the temperature measurement sensor 12 is transmitted to the control unit 11. [ The analog type electrical signal output from the temperature measurement sensor 12 is converted into a digital signal by the analog-to-digital converter included in the control unit 11. [

The control unit 11 receives signals from the water quality sensor 10 and the temperature sensor 12 to determine whether the water quality and temperature of the pool water are abnormal or not. The controller 11 controls the flocculation agent 4, the ozone generator 5, The heat exchanger 8, the chemical injector 9, the chlorine generator 13, and the like. The control unit 11 is a PLC (Programmable Logic Controller). A direct digital controller (DDC), or a digital signal controller (DSC). The control unit 11 and the facilities are connected by a data transmission channel for transmitting and receiving control signals. Data transmission and reception between the water quality measurement sensor 10 and the temperature measurement sensor 12 may be in the form of wired or wireless data communication and the control unit 11 may be connected to the coagulation agent 4, the ozone generator 5, the heat exchanger 8 ), The medicine injector 9 and the chlorine generator 13 may also be in the form of wired / wireless data communication.

The control unit 11 determines whether the residual chlorine concentration, the hydrogen ion concentration (pH), and the turbidity are at an appropriate level, that is, satisfies the legal criteria shown in Table 1, using the data received from the water quality measurement sensor 10. In this case, it is recommended to maintain the residual chlorine concentration at 0.4 to 1.0 mg / L, pH 5.8 to 8.6 and turbidity at 2.8 NTU or less, but the residual chlorine concentration More preferably 0.45 to 0.95 mg / L, the hydrogen ion concentration (pH) of 7 to 8, and the turbidity of 2.5 NTU or less.

The control unit 11 controls the operation of the chemical injector 9 and the chlorine generator 13 when the measured residual chlorine concentration deviates from the reference. That is, if the residual chlorine concentration exceeds the reference range, the control unit 11 first operates the chlorine generator 13 to generate chlorine (Cl 2 ). The chlorine generated in the chlorine generator 13 is transferred to the chemical injector 9, and the chemical injector 9 mixes the chlorine with the water circulated in the pool through the pumping process. The chlorine-supplemented water is fed to the pool water tank 1 through the chemical feeder 9 to replenish the chlorine in the pool water tank 1. The residual chlorine concentration is regulated by additionally introducing chlorine or by stopping the operation of the chemical injector 9 in operation.

The water quality sensor 10 can continuously measure the residual chlorine concentration even during the process in which chlorine is generated in the chlorine generator 13 and transferred to the chemical injector 9 to replenish the chlorine. That is, while the chlorine is continuously supplied, the residual chlorine concentration is continuously measured using the water quality sensor 10, and when the residual chlorine concentration is within the reference range, the operation of the chlorine generator 13 may be automatically stopped have. The process of stopping the operation of the chlorine generator 13 when the replenishing of chlorine is completed while continuously measuring the residual chlorine concentration can be controlled by the control unit 11. [ Meanwhile, the chlorine generator 13 may be operated in such a manner that the operation and the operation are repeatedly stopped at predetermined time intervals.

When the hydrogen ion concentration (pH) deviates from the standard, the control unit 11 controls the drug injector 9 to adjust the hydrogen ion concentration (pH). That is, when the water quality is determined to be alkaline due to a high pH (pH), the chemical feeder 9 is operated to change the water quality to neutrality by inputting hydrochloric acid and conversely, the water quality is low (9) is activated, sodium hydroxide or the like is put into the bath to adjust the pH to neutrality. It is needless to say that other chemicals besides hydrochloric acid or sodium hydroxide can be used for controlling the pH of the solution. When the turbidity is out of the reference value, the control unit 11 can control the operation of the flocculation agent 4 to adjust the amount of flocculant to be added.

The control unit 11 receives data from the temperature measurement sensor 12, and controls the water temperature of the pool water tank 1 to be maintained and maintained at an appropriate temperature. Since a large amount of water is contained in the pool water tank 1 and the temperature may be different depending on the location, a plurality of temperature measurement sensors 12 may be installed in the pool water tank 1 as described above, It is possible to receive the data from the plurality of temperature measurement sensors 12 and finally determine the temperature of the water contained in the pool water tank 1. [ The control unit 11 can take an average value by using the data transmitted to the plurality of temperature measurement sensors 12 and judge it as the temperature of the water contained in the pool water tank 1 and perform the control. When the temperature of the pool water tank 1 is lower than the reference value, the heat exchanger 8 can be operated to supply heat (hot water). If the temperature is higher than the reference value, the operation of the heat exchanger 8 can be stopped. Further, the water supply device 2 may be adjusted to adjust the temperature by further adding water. The temperature of the water can be adjusted, for example, within a range of about 27 ° C to 30 ° C, and more specifically, within a range of about 28 ° C to 29 ° C.

The residual chlorine concentration and the hydrogen ion concentration (pH) of the water contained in the swimming pool water tank 1 depend on the temperature of the water contained in the swimming pool water tank 1. Therefore, it is appropriate that the control unit 11 preferentially adjusts the temperature of the water prior to adjusting the residual chlorine concentration and the hydrogen ion concentration (pH). That is, if the temperature of the water contained in the pool water tank 1 is first adjusted within the reference range, and then the chemical feeder 9 or the chlorine generator 13 is operated to adjust the residual chlorine concentration and the hydrogen ion concentration (pH) It is possible to achieve the intended residual chlorine concentration and the hydrogen ion concentration (pH) accurately.

Specifically, when the residual chlorine concentration deviates from the reference value, the control unit 11 does not immediately operate the chlorine generator 13 but operates the heat exchanger 8 to adjust the temperature of the water to an appropriate level. When the control of the temperature is completed, the water having been subjected to temperature control is sampled again to check the residual chlorine concentration again. If it is confirmed that the residual chlorine concentration is still out of the normal range even after the temperature is adjusted, 13). As described above, once the temperature of the water is adjusted and the residual chlorine concentration is checked again, it is possible to prevent the generation of unnecessary chlorine, and furthermore, the residual chlorine concentration can be controlled more accurately.

In addition, the control unit 11 can monitor the condition of facilities such as the flocculation agent 4, the ozone generator 5, the heat exchanger 8, the chemical injector 9, and the chlorine generator 13. For example, the controller 11 always checks the voltage applied to the electrodes of the chlorine generator 13, and can provide an alarm to the manager when the voltage is out of a predetermined range.

The control unit 11 monitors the water quality or temperature of water and can provide an alarm when an abnormality occurs that exceeds the reference value. It is also possible to provide an alarm when an operation error occurs in facilities such as the flocculation agent 4, the ozone generator 5, the heat exchanger 8 and the medicine injector 9. The alarm provided by the control unit 11 may be provided using a panel installed inside the swimming pool, but it may also provide an alarm to a portable terminal having a manager. To this end, the pool management system according to the present invention may further include a portable terminal possessed by the manager.

The alarm transmitted to the manager's portable terminal may be a text message, an alarm sound, or a pop-up form provided by a monitoring application installed in the portable terminal. In this way, the controller 11 is connected to the Internet network so that the controller 11 can provide an alarm to the manager's portable terminal. The process of connecting the control unit 11 with the Internet network can be performed through an LTE modem or the like.

The administrator can control the operation of the facilities installed in the pool through an application program installed in the portable terminal. That is, the control unit 11 can automatically control various facilities to maintain the water quality and the temperature as a reference value when there is an abnormality in the water quality and the temperature. However, the control process for such facilities is performed by an application installed in the portable terminal It can also be done through a program. As a result, even when the manager is located at a remote location, the user can grasp the state of the pool water or the facility in real time, and if necessary, can directly control the remote site. Accordingly, when there is an abnormality in the water quality, the temperature, or the facilities of the swimming pool water, it is possible to easily and promptly cope with it.

And may include a flow switch (not shown) for controlling the quantity.

The chlorine generator (13) generates chlorine through electrolysis of the brine (17). In order to appropriately adjust the amount of chlorine generated in the chlorine generator 13, it is necessary to precisely control the concentration and volume of the brine 17 and the distance between the electrodes 15 and 16. In the present invention, 100-300 L of salt water (17) is prepared, and the concentration of the salt water (17) is 600 to 800 ppm.
