[0063] Where: T mix is the theoretical mixed water temperature value at the i-th test, Q hot Q is the total hot water flow of the hot water main 8 detected by flow sensor 1, cold is the total flow of the cooling water pipe 13 detected by the flow meter 15; T cold T is the temperature of the cold water in the cold water main 18 detected by the temperature sensor 2; hot is the temperature of the hot water in the hot water main pipe 8 detected by the temperature sensor 1, ln is a logarithmic function; T0 is the initial temperature value in the mixing chamber 30 at the i-th detection by the temperature sensor 3, e is 2.71, t i is the end time of the i-th detection, t0 is the start time of the i-th detection; T1 is the unit temperature; t is the unit time;

[0064] Calculation module 2, based on the result of calculation module 1, uses the following formula 2 to calculate:

[0065] Where: P i is the regulating power value required by the cold water circulation pump 14, ρ is the water density, which is 1; g is the gravity acceleration, which is 10, t f is the adjustment time period, H0 is the head of the cold water circulation pump 14 in the adjustment time period, G0 is the flow rate of the cold water supply pipe 13 in the adjustment time period detected by the flow meter 15, To adjust the efficiency of the cold water circulation pump 14 within the time period, H f is the head of the hot water circulation pump 3 during the adjustment period, G f is the hot water flow value in the hot water supply pipe 4 detected by the flow sensor 1 during the adjustment time period, T4 is the mixed water temperature value before adjustment at the outlet pipe 35 detected by the temperature sensor 4 during the adjustment period.

[0066] The working principle and beneficial effects of the above technical solution are as follows: when the intelligent sensor module works, the temperature sensor first detects the hot water temperature data in the hot water pipe 8 and transmits it to the controller 33. At the same time, the temperature sensor 2 detects the temperature data of the cold water in the cold water pipe 18 and transmits it to the controller 33. The temperature sensor 3 detects the initial temperature value in the mixing water chamber 30 and transmits it to the controller 33. The temperature sensor 4 synchronously detects the mixed water temperature value at the outlet pipe 35 and transmits it to the controller 33. The flow sensor 1 simultaneously detects the hot water flow value in the hot water supply pipe 4 and transmits it to the controller 33. The controller 33 controls the calculation module 1 to work and calculate the theoretical mixed water temperature. Then the calculation module 2 works to calculate the cold water circulation. The adjustment power value required by the pump 14, when there is a difference between the theoretical mixed water temperature and the mixed water temperature value, the controller 33 controls the cold water circulation pump to adjust according to the adjustment power value, when the mixed water temperature of the mixing and hot water station is too low, the controller 33 reduces the power of the cold water circulation pump 14, reduces the cold water input per unit time, to increase the mixed water temperature; when the mixed water temperature is too high, the controller 33 reduces the mixed water temperature by increasing the power of the cold water circulation pump 14 and increasing the cold water input per unit time; the processing module starts to work, when the adjustment power value is greater than the rated power of the cold water circulation pump 14 and the hot water circulation pump 3, the alarm sounds, the mixing water mechanism 28 stops running, and fault maintenance is required; the alarm is used to alarm in abnormal situations;

[0067] This embodiment designs the intelligent sensor module in detail, and realizes real-time monitoring and flow control of hot water, cold water, mixing chamber and outlet water temperature by configuring multiple temperature sensors and flow sensors. These sensor data provide a rich basis for decision-making for the controller, so that the controller can accurately adjust the flow rate and mixing ratio of hot and cold water according to actual needs, thereby realizing intelligent and precise control of the mixed water temperature. At the same time, the setting of the alarm can sound an alarm in time when an abnormal situation occurs, thereby improving the safety and reliability of the system. This embodiment realizes comprehensive monitoring and precise control of the mixing water regulation system by improving the functions of the intelligent sensor module, further improving the intelligence level and operation efficiency of the system. .
