Generally, the small swimming pool is usually 5-10 m long, 1.5-3 m wide and less than 2m deep; at one end of the swimming pool in the length direction, the water pump drives the water in the swimming cylinder to flow; if the speed of the swimmer exceeds the water speed, the swimmer can gradually approach the front end of the swimming cylinder body and easily bump against the head or the arms; if the speed of the swimmer cannot keep up with the speed, the swimmer can be pushed backwards by water flow, and when the swimmer breaks water with legs and feet, the swimmer is easy to break the swimming cylinder to cause injuries and the like. In order to reduce the above injuries, pull rods or pull ropes are generally used in the market, the body of the swimmer is tied with a flexible object, the length of the rope is adjusted, and the pull rope pulls the swimmer to keep the swimmer in a proper position so as to prevent the swimmer from colliding with the front wall and the rear wall of the swimming tub.

The control system 1 reads that the coordinate point of the human body position is a null value, that is, the position detection device 5 cannot detect the human body, that is, the user does not enter the swimming pool for swimming, so the control logic can play a role in energy conservation, and energy waste is avoided.T 1 > t 0 + T 0 In order to ensure that the control system 1 can read the coordinate point of the human body position detected by the detection device at least once, and avoid the situation that the coordinate point is detected by the detection device at least onceT 1 The setting is too short, resulting in failure of the control system 1 to operate normally.T 1 The value range of (1) is 3-180 s; in the present embodiment, it is preferred that,t 0 the value range of (A) is preferably 3-5 s,T 1 the value of (c) is preferably 15 s.
After receiving a start command from the control system 1T 1 Within the time, if the control system 1 reads a coordinate point of the human body position; then the coordinate point of the currently read human body position is recorded asL t0+xT0 Respectively recording the coordinate points of the human body position read beforeL t0+(x-1)T0 ，L t0+(x-2)T0 ，L t0+(x-3)T0 ，L t0+(x-4)T0 ，...，L t0+(x-i)T0 (ii) a Coordinate the position of the human bodyL t0+xT0 The corresponding water flow velocity is recordedV t0+xT0 (ii) a Coordinate the position of the human bodyL t0+(x-1)T0 The corresponding water flow velocity is recordedV t0+(x-1)T0 . I.e. the coordinates of the current body position areL t0+xT0 The coordinates of the previous human body position areL t0+(x-1)T0 The coordinates of the human body positions of the first two times areL t0+(x-2)T0 The coordinates of the human body position of the first three times areL t0+(x-3)T0 The first four times of human body position coordinates areL t0+(x-4)T0 By analogy, beforeThe next human body position coordinate isL t0+(x-i)T0 。
When in useL M1 ≤L t0+xT0 ≤L M0 When the swimming pool is running, the control system 1 controls the swimming water pump 3 to make the water flow speed in the swimming poolV t0+xT0 = V t0+(x-1)T0 +[( L t0+(x-1)T0 +...+ L t0+(x-i-1)T0 )/(i+1)-( L t0+xT0 +...+ L t0+(x-i)T0 )/( i+1)]/ T 0 If, ifV t0+xT0 >V max Then, thenV t0+xT0 = V max (ii) a In the above expression, if one item of the coordinate point of the human body position read by the control system 1 is null, thenV t0+xT0 = V t0+(x-1)T0 。
When in useL t0+xT0 ＜L M1 When the swimming pool is running, the control system 1 controls the swimming water pump 3 to make the water flow speed in the swimming poolV t0+xT0 = V t0+(x-1)T0 +K 1 *|( L t0+(x-1)T0 +...+ L t0+(x-i-1)T0 )/( i+1)-( L t0+xT0 +...+ L t0+(x-i)T0 )/( i+1)|/ T 0 If, ifV t0+xT0 > V max Then, thenV t0+xT0 = V max (ii) a Wherein the coefficientsK 1 =( L M1 -L F )/[( L t0+xT0 +...+ L t0+(x-i)T0 )/( i+ 1)- L F ]And when(L t0+xT0 +...+ L t0+(x-i)T0 )/( i+1)- L F ≤0When the temperature of the water is higher than the set temperature,V t0+xT0 = V max (ii) a In the above expression, if one item of the coordinate point of the human body position read by the control system 1 is null, thenV t0+xT0 = V t0+(x-1)T0 ；
When in useL t0+xT0 ＞L M0 When the swimming pool is running, the control system 1 controls the swimming water pump 3 to make the water flow speed in the swimming poolV t0+xT0 =K 2 *|(L t0+(x-1)T0 +...+ L t0+(x-i-1)T0 )/( i+1)-( L t0+xT0 +...+ L t0+(x-i)T0 )/( i+1)|/T 0 If, ifV t0+xT0 ＜V min Then, thenV t0+xT0 = V min (ii) a Wherein the coefficientsK 2 =(L B - L M0 )/[ L B -( L t0+xT0 +...+ L t0+(x-i)T0 )/( i+1)]And whenL B -( L t0+xT0 +...+ L t0+(x-i)T0 )/( i+1)≤0When the swimming pool is started, the control system 1 controls the swimming water pump 3 to be closed; in the above expression, if one item of the coordinate point of the human body position read by the control system 1 is null, thenV t0+xT0 = V t0+(x-1)T0 。
In the above-mentioned formula,L t0+xT0 the current position of the human body is shown in the embodiment of the inventionThe value range of (a) is between 0 and 5, preferably 2。
In addition, in the above expression, if one term of the coordinate point of the human body position read by the control system 1 is null, the coordinate point is determined to be nullV t0+xT0 = V t0+(x-1)T0 . The expression means: if the data volume of the coordinate point of the human body position cannot meet the calculation requirement of the formula, the water flow speed still keeps the last time. By such an arrangement, operation can be achieved when the coordinates are not detected during swimming, for example during diving.
For ease of understanding, the description will now be made by way of example:
hypothesis spaceT 0 The reaction time is 1s, and the reaction time is,t 0 at 3s, initial swimming speedV 0 Is 0.5m/s, and is,iis 2;
suppose at the first intervalT 0 When the swimmer swims with water, namelyt 0 + T 0 When the time is =4s, the control system 1 reads that the coordinate point of the human body position is 4m for the first time; then the coordinate point of the currently read human body positionL t0+xT0 I.e. equal to 4m, but the coordinate point read last timeL t0+(x-1)T0 Is null, so the water flow rate is 0.5 m/s;
suppose in the second intervalT 0 When is at timet 0 +2T 0 When the time is =5s, the control system 1 reads that the coordinate point of the human body position is 4.2m for the second time; then the currently read coordinate point of the position of the human bodyL t0+xT0 I.e. 4.2m, position coordinate point of human body read last timeL t0+(x-1)T0 I.e. equal to 4m, but the coordinate points of the position of the human body read in the first two timesL t0+(x-2)T0 Is null, so the water flow rate is 0.5 m/s;
suppose in the third intervalT 0 When is at timet 0 +3T 0 When the coordinate point is read for the third time, the control system 1 reads that the coordinate point of the human body position is 4.4 m; then the currently read coordinate point of the position of the human bodyL t0+xT0 Namely, etcAt 4.4m, the position coordinate point of the human body read last timeL t0+(x-1)T0 Namely, the coordinate point of the human body position which is equal to 4.2m and is read in the previous two timesL t0+(x-2)T0 I.e. equal to 4m, but read the position coordinates of the human body the first three timesL t0+(x-3)T0 The water flow speed is still 0.5m/s at the moment because the water flow speed is null;
suppose in the fourth intervalT 0 When is at timet 0 +4T 0 When the coordinate point is read for the fourth time, the control system 1 reads that the coordinate point of the human body position is 4.6 m; then the currently read coordinate point of the position of the human bodyL t0+xT0 Namely, the coordinate point of the human body position which is equal to 4.6m and is read in the previous timeL t0+(x-1)T0 Namely, the coordinate point of the human body position which is equal to 4.4m and is read in the previous two timesL t0+(x-2)T0 I.e. equal to 4.2m, the position coordinate point of the human body is read for the first three timesL t0+(x-3)T0 I.e. equal to 4 m; now judgeL t0+xT0 In which range section, i.e. in which section 4.6 is determined, for convenience of explanation, it is assumed thatL M1 ≤4.6≤L M0 At the fourth intervalT 0 Time, water velocityV t0+4T0 = V t0+3T0 +(4.4+4.2+4)/3-(4.6+4.4+4.2)/3=0.5+(4.2-4.4)=0.3m/s。
It can be seen from the above water flow speed adjusting process that the water flow speed of the swimming pool control method of the present invention is dynamically adjusted, so that the water flow speed can be ensured to be adapted to the swimming speed of the swimmer, the swimmer can be kept in a safe area, and the swimmer is not required to be limited by using a pulling rod (pull rod, pull rope, etc.) in the above process, thereby avoiding scratching. The invention avoids the problems of poor usability, inconvenient use, discomfort and the like in the prior art; through rivers control, improved swimmer's travelling comfort and experienced, realized continuously along with the free swimming freely, avoided because the swimming that the speed mismatch leads to pauses to can optimize the power consumption, improve the cost-effectiveness ratio.
Preferably, it is also possible to design in the control system 1Length of time for swimmingTI.e. receiving a start instruction from the control system 1TAfter the time, the control system 1 controls the swimming water pump 3 to be closed, and the swimming is finished. The swimming time is set, the control system 1 automatically turns off the swimming water pump 3 after the set swimming time is reached, on one hand, energy waste can be avoided, and on the other hand, the swimming time can play a role in swimming person movement planning.
Preferably, the operation panel 2 is available for display. Namely, the operation panel 2 can intuitively display various swimming data when the swimmer has a demand. Such as swimming speed, swimming duration, etc.
It should be noted that, in the embodiment of the present invention, the swimmer may wear the bracelet to facilitate the detection by the position detection device 5, that is, the position detection is performed through the wireless communication between the bluetooth module and the bracelet.

Wherein the secure area means: when people swim in the area, the body parts of the swimmers cannot touch the walls at the upstream and downstream ends of the swimming pool, so that the injury can be avoided; the early warning area means that when a swimmer swims in the area, the body part of the swimmer risks touching the walls of the upstream and downstream ends of the swimming pool, and the injury can be caused. In this step, each coordinate point may be set according to the size of the actual swimming pool and the size of the user, as long as the set coordinate point can satisfy the functions of the safety area and the early warning area; setting an initial swimming speed in the control system 1V 0 .

The coordinate point of the human body position read by the control system 1 is null, that is, the position detection device 5 cannot detect the human body, that is, the user does not enter the swimming pool for swimmingThen, the control logic can play a role in energy conservation, and energy waste is avoided.T 1 > t 0 + T 0 In order to ensure that the control system 1 can read the coordinate point of the human body position detected by the detection device at least once, and avoid the situation that the coordinate point is detected by the detection device at least onceT 1 The setting is too short, resulting in failure of the control system 1 to operate normally.T 1 The value range of (1) is 3-180 s; in the present embodiment, it is preferred that,t 0 the value range of (A) is preferably 3-5 s,T 1 the value of (c) is preferably 15 s.
