[0021] Furthermore, in order to improve the antifreeze ability of the water tank 1 in the solar intelligent water storage and supply system in this embodiment, the water tank 1 is buried below the frozen soil layer. Usually, the outside of the water tank 1 is also wrapped with insulation materials.
[0022] Furthermore, the solar intelligent water storage and supply system in this embodiment also includes a temperature detection module, which includes a temperature sensor 17 for detecting the external ambient temperature, and the temperature sensor 17 is connected to the controller 15 by signal; a drain valve 18 is provided on the connecting pipe between the second water pump 4 and the water use point, and the drain valve 18 is connected to the controller 15 by signal.
[0023] Furthermore, it also includes a display module, which includes a display 19. The display 19 is connected to the controller 15 by signal and is used to receive and display water quality and temperature information.
[0024] The working process of the intelligent water storage and supply system in this embodiment is as follows: first, control to start the first water pump 3, so that it draws water from the external water source to the water tank 1, until the water in the water tank 1 is full of water to the upper liquid level sensor, and control to close the first water pump 3. At this time, the water quality in the water tank 1 is detected by the water quality sensor 5, and the corresponding data is transmitted to the controller 15. Then the controller 15 sends corresponding opening and closing instructions to the three-way valve 13 and the four-way valve 14 or the drain valve 2 according to the program setting, and then controls to start the second water pump 4, and correspondingly controls to start the filtering device 6 and the disinfecting device 7, so that the water in the water tank 1 selects different purification routes for purification and water supply, or in the water When the water quality is too bad, purification is abandoned and the drain valve 2 is directly started to drain all the stored water. When the water in the water tank 1 is lower than the lower liquid level sensor, the second water pump 4 or the drain valve 2 is controlled to be closed, and the first water pump 3 is controlled again to pump water for the next cycle. On the other hand, when the climate is in a cold stage, the temperature sensor 17 provided in the system can monitor the occurrence of extreme temperatures in real time, and transmit the external environmental temperature data collected in real time to the controller 15. The controller 15 is set according to the program. When the temperature drops to the set temperature, the drain valve 18 is controlled to start, and all the water in the water supply pipe is drained to avoid ice in the subsequent pipe.
[0025] The system can select the purification method according to the different water qualities in the water tank 1 in a complex working environment, which is more adaptable, can avoid ineffective purification and excessive purification, and achieve self-cleaning; secondly, the intelligent antifreeze function also makes the system more capable of coping with extreme cold conditions, avoiding frostbite of equipment and pipelines, and achieving antifreeze.
[0026] Example 2 The present embodiment discloses a solar intelligent water storage and supply system control method based on the above-mentioned embodiment 1, characterized in that when the turbidity of the water in the water tank 1 is ≥ t1 and < t2, the controller 15 controls the three-way valve 13 to open the passage of the first pipe 8 and close the passage of the first branch 11, so that the water in the water tank 1 flows through the filtering device 6; when the turbidity of the water in the water tank 1 is < t1, the controller 15 controls the three-way valve 13 to open the passage of the first branch 11 and close the passage of the first pipe 8, so that the water in the water tank 1 does not flow through the filtering device 6; when the TOC value of the water in the water tank 1 is ≥ t3 and < t4 or the pH value is ≥ t5 and < t6 or the OPR value is ≥ t7 and < t8, the controller 15 controls the four-way valve 14 to open The passage from the second pipe 9 or the passage from the first branch 11 to the second pipe 9 is opened, and the passage from the second branch 12 is closed, so that the water in the water tank 1 flows through the disinfection device 7; when the TOC value of the water in the water tank 1 is less than t3 or the pH value is less than t5 or the OPR value is less than t7, the controller 15 controls the four-way valve 14 to open the passage from the second pipe 9 to the second branch 12 or the passage from the first branch 11 to the second branch 12, and closes the passage from the second pipe 9, so that the water in the water tank 1 does not flow through the disinfection device 7; when the turbidity of the water in the water tank 1 is ≥ t2 or the TOC value is ≥ t4 or the pH value is ≥ t6 or the OPR value is ≥ t8, the controller 15 controls the drain valve 2 to operate, and pumps the water in the water tank 1 out of the water tank 1.
[0027] Of course, when other types of water quality sensors 5 other than those in this embodiment are selected, the corresponding settings will also change, but the control logic remains the same as described above.
[0028] Furthermore, when the external environment temperature is less than t9, the controller 15 controls the drain valve 18 to operate, so as to drain the water in the first pipeline 8 , the second pipeline 9 , the third pipeline 10 , the first branch 11 , and the second branch 12 .
[0029] Furthermore, when the water storage period of the water storage tank 1 is ≥ t10, the controller 15 controls the drain valve 2 to operate, so as to pump the water in the water storage tank 1 out of the water storage tank 1 .
[0030] It should be noted that the above thresholds t1, t2, t3, t4, t5, t6, t7, t8, t9, and t10 need to be determined based on actual water usage, so their numerical values are not specifically limited here.
[0031] Furthermore, the following steps are included: S1: inputting the turbidity upper and lower thresholds t1 and t2, TOC upper and lower thresholds t3 and t4, PH upper and lower thresholds t5 and t6, OPR upper and lower thresholds t7 and t8, external environment temperature threshold t9 and water storage period threshold t10 into the controller 15; S2: Collecting water quality and temperature information in real time through the water quality sensor 5 and the temperature sensor 17, and transmitting the data information to the controller 15; S3: Compare and calculate the actual water quality index values and the external environment temperature index values monitored in real time by the water quality sensor 5 and the temperature sensor 17 with the various thresholds input into the controller 15, and then control the operation of corresponding components through the controller 15 to perform separate or coordinated operation of different actions such as filtration, disinfection, and drainage, as well as pipeline venting.
[0032] Furthermore, the controller 15 adopts a fuzzy controller, and the actual water quality index values monitored in real time by the water quality sensor 5 and the temperature sensor 17 are converted into fuzzy quantities such as cleaning threshold error EC, cleaning threshold error change rate ECC and climate threshold error EC1, and climate threshold error change rate ECC1 through the controller. The controller 15 performs fuzzy reasoning calculations on the fuzzy quantities through self-cleaning water storage fuzzy inference rules, and then defuzzifies the output quantity, and finally inputs corresponding instructions according to the results to realize self-cleaning fuzzy control that performs independent operation or coordinated operation of intelligent switching of different actions such as filtration, disinfection, and drainage according to different water quality levels, and anti-freeze fuzzy control that performs pipeline emptying according to different climate levels.
