Specifically, utilize the interconnection line to connect high district water mixing unit and low district water mixing unit, form and ally oneself with water mixing unit more to install electric regulator on the interconnection line, control functions such as unusual operating mode that water mixing unit appears more, meticulous regulation through remote instruction. Monitoring the water pressure of a high-area water mixing unit and a low-area water mixing unit through a water pressure monitoring device to respectively obtain respective water pressure values, analyzing and calculating according to the high-area water pressure and the low-area water pressure values to obtain a water pressure average value and a water pressure price difference, wherein the water pressure average value is subjected to weighted calculation through the high-area water pressure and the low-area water pressure to obtain a water pressure average value, namely (a first water pressure value + a second water pressure value)/2, then respectively calculating a difference value between the high-area water pressure, the low-area water pressure and the water pressure average value, calculating a difference value by utilizing the two difference values, and obtaining a water pressure range by combining with the water pressure average value calculation, wherein a first difference value = (the first water pressure value-average water pressure value)/the; a second difference rate (second water pressure value-average water pressure value)/average water pressure value, wherein the average water pressure difference rate is obtained by averaging the sum of the first difference rate and the second difference rate, the water pressure range is between the average water pressure value (1-average water pressure difference rate) and the average water pressure value (1 + average water pressure difference rate), then whether the first water pressure value meets the water pressure range is judged, according to the general experience and physical principle, the water pressure value of the high region is smaller than that of the low region, if the water pressure value of the high region meets the water pressure range condition, the water pressure value of the low region is usually met, so that the water pressure of the high region water mixer set is preferentially judged, when the water pressure value of the high region does not meet the water pressure range, a corresponding control instruction is obtained, a signal is sent to the electric regulator through an interconnection line, the electric regulator regulates the water pressure of the high region according to the received control instruction, make the high district water pressure after the regulation satisfy the water pressure within range to guarantee high district, low water pressure's stability, thereby guaranteed water mixing system's stability, make the water pressure keep balance in mixing the water pipe, thereby have increase of service life, guarantee the technological effect of mixing the water effect. And then solved among the prior art pressure control unstable among the water mixing system, there is the water supply temperature change, can not guarantee to mix the water effect, and influence life's technical problem.

Further, after determining whether the first water pressure value satisfies the water pressure range, the method includes: judging whether the second water pressure value meets the water pressure range or not; and when the second water pressure value does not meet the water pressure range, obtaining a second control instruction, wherein the second control instruction is used for controlling the electric regulator to regulate the second water pressure value, so that the second water pressure value is regulated to be within the water pressure range.

Specifically, when the first water pressure value is judged not to satisfy the water pressure range, whether the second water pressure value satisfies the water pressure range is judged, if the first water pressure value satisfies the water pressure range, the high region satisfies the water pressure requirement, the low region is usually satisfied, and if the high region does not satisfy the water pressure requirement, the low region may not satisfy the water pressure requirement, so that the water pressure of the low region is further judged, whether the requirement of the water pressure range is satisfied is judged, if the water pressure of the low region does not satisfy the requirement of the water pressure range, a corresponding control instruction is obtained, the control instruction is sent to the electric regulator, the water pressure of the water mixing unit of the low region is finely regulated, the water pressure of the low region is in accordance with the water pressure range, the water pressure of each region in the water mixing unit is ensured to be in a stable range, and the water mixing effect is ensured.

Further, after determining whether the second water pressure value satisfies a first predetermined threshold, the method includes: when the first water pressure value and the second water pressure value both meet the water pressure range, obtaining a first temperature value of the high-area water mixing unit; obtaining a second temperature value of the low-region water mixing unit; obtaining a first temperature difference value according to the first temperature value and the second temperature value; judging whether the first temperature difference value meets a first preset threshold value or not; when the first temperature difference value meets the first preset threshold value, judging whether the first temperature value meets a preset temperature or not, wherein the preset temperature comprises a highest preset temperature and a lowest preset temperature, and the difference value between the highest preset temperature and the lowest preset temperature is smaller than the first preset threshold value; when the first temperature value does not meet the lowest preset temperature, obtaining a second temperature difference value according to the first temperature value and the lowest preset temperature; comparing the first temperature difference value with the second temperature difference value; and when the first temperature difference is larger than the second temperature difference, obtaining a third control instruction, wherein the third control instruction is used for controlling the electric regulator to regulate the high-area water mixing unit.

Specifically, in addition to the stable control of the water pressure, the temperature is also controlled to a predetermined level by fine control, the water temperatures of the high area and the low area are respectively monitored by the temperature monitoring devices, a first temperature value and a second temperature value are respectively obtained, a difference between the temperatures of the high area and the low area is calculated, whether the temperature difference is within a reasonable range is judged, the range is a smaller difference range and is usually set to a value within 10 or less, if the first temperature difference meets a predetermined requirement, whether the temperature meets a preset temperature requirement is judged, the preset temperature is the temperature of the water mixing unit set according to the temperature requirement, can be set to a specific temperature value, or can be a range, for better control, usually is a range, but the range of the preset temperature is smaller than the difference range, namely the provision of a first predetermined threshold, so as to ensure the stability of the temperature control, if the difference is greater than a predetermined value, the temperature stability is lost, and if the first predetermined threshold is within 10 degrees of the difference, the given predetermined temperature range is less than 10, e.g., within a range of 50-55 ℃, 5 ℃ is less than 10 ℃ of the first predetermined threshold, and preferably the first predetermined threshold is not greater than twice the predetermined temperature range, i.e., 10 is not greater than 2 x 5. In addition, the water temperature is regulated by the industry standard < < technical regulation of ground radiant heating > JGJ142-2004 of the people's republic of China to have the following points: the temperature of the supply water and the return water of the 3.1.1 low-temperature hot water ground radiation heating system should be determined by calculation, the water supply temperature of the civil building is preferably 35-50 ℃, the temperature of the supply water and the return water is not more than 60 ℃, and the temperature difference of the supply water and the return water is preferably less than or equal to 10 ℃. The maximum water temperature is not more than 60 ℃ which is the most important index influencing the use safety of the floor heating, the strict adherence is required for the safety of the floor heating, and the temperature has great influence on the service life and the aging performance of the floor heating pipe, for example, the service life of a PE-RT pipe is below 60 ℃ and can reach 50 years. The temperature of 70 ℃ is reduced to 10 years, the temperature of 80 ℃ is only 5 years, the temperature of 90 ℃ is only one year, and the data can be seen from a service life curve chart provided by related pipe manufacturing enterprises, so that the water temperature control has very important significance for the use safety of the floor heating. The accurate control of the temperature can greatly prolong the service life of the floor heating pipe (when the temperature is high, the floor heating pipe becomes soft, the floor heating pipe at the water separator is easy to be separated, in addition, the service life can be reduced, and the premise that each large pipe factory keeps 50 years is that the water temperature is below 60 ℃, if the water temperature exceeds 60 ℃, the pipe explosion factory is not responsible), so the highest preset temperature value in the set preset temperature is less than 60 ℃. And when the temperature of the high area does not meet the lowest preset temperature, if the preset temperature is set to be 50-55 ℃, and the first temperature value is 45 ℃, the requirement of the lowest preset temperature of 50 ℃ is not met. When the difference value is not satisfied, obtaining a difference value, namely 50-45=5 ℃ is a second temperature difference value, comparing the first temperature difference value with the second temperature difference value, wherein the second temperature difference value is large, if the first temperature difference value is smaller than the second temperature difference value, the temperature of the low region meets the lowest preset temperature, because the water pressure of the low region is easier to reach, the high region needs to be directly supplied, and the middle pressurizing temperature of the high region is influenced to a certain extent, if the difference value between the temperature of the low region and the temperature of the high region is 8 ℃, 8 ℃ is smaller than a first preset threshold value 10 ℃, the temperature of the low region is 45+8=53 ℃ and is larger than 50 ℃, the temperature of the high region only needs to be adjusted, and the return water temperature of the high region is increased by controlling an electric regulator, so that the temperature of the high region meets the preset temperature, and the temperature.

Further, after comparing the first temperature difference value with the second temperature difference value, the method includes: and when the first temperature difference value is smaller than the second temperature difference value, obtaining a fourth control instruction, wherein the fourth control instruction is used for controlling the electric regulator to respectively regulate the high-region water mixing unit and the low-region water mixing unit.

Specifically, when the direct difference between the high area and the preset temperature is smaller than the difference between the high area temperature and the low area temperature, it is indicated that the temperature of the low area does not meet the preset temperature, and when the temperatures of the low area and the high area need to be adjusted, corresponding control instructions are obtained, the water mixing units of the high area and the low area are adjusted respectively, so that the temperatures of the water mixing units meet the preset conditions, thereby ensuring the water mixing effect of the high area and the low area.

Further, after determining whether the first temperature difference value satisfies a first predetermined threshold, the method includes: when the first temperature difference value does not meet the first preset threshold value, judging whether the second temperature value meets the preset temperature or not; and when the second temperature value meets the preset temperature, obtaining a fifth control instruction, wherein the fifth control instruction is used for controlling the electric regulator to regulate the high-area water mixing unit.

Specifically, when the temperature difference between the low zone and the high zone is too large and does not satisfy the first predetermined threshold, the second temperature value with a higher temperature is used to compare with the highest predetermined temperature in the predetermined temperatures, if the second temperature value satisfies the predetermined temperature, that is, the second temperature value with a higher temperature is smaller than the highest predetermined temperature and larger than the lowest predetermined temperature, and because the temperature difference between the first temperature value and the second temperature value is too large and exceeds the range of the first predetermined threshold, because the range of the first predetermined threshold is larger than the temperature difference between the highest predetermined temperature and the lowest predetermined temperature in the predetermined temperatures, if the second temperature value with a high temperature conforms to the range, the first temperature value with a large difference range is certainly not within the range requirement of the predetermined temperatures, and the high-zone water mixing unit needs to be adjusted, so that the first temperature value satisfies the requirement of the predetermined temperature, and the effect of adjusting the temperature balance is achieved, and the water mixing effect is ensured when the water mixer works in a smaller temperature difference range.
