Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of motor regulation, and specifically to a motor regulation system and method based on artificial intelligence. Background Art
[0002] Through artificial intelligence, it is possible to control a variety of devices over a wide range, and the data call is basically synchronized. At the same time, with the rise of the water treatment industry in China, the types and quantities of equipment in the water treatment system are becoming more complex. The system often uses artificial intelligence to ensure the safe and stable operation of the system through established programs. For example, in the reverse osmosis membrane filtration part of the water treatment system, the system usually sets the start and stop of the RO water pump according to the water levels in the front and rear water tanks of the RO water pump.
[0003] Since the water consumption of users changes at any time, when it is difficult to determine the consumption rate of the water production of the RO membrane, it may cause the motor in the RO water pump to start and stop frequently, which is extremely harmful to the control period and motor loss, and increases unnecessary safety risks. On the one hand, when setting the established program for the water treatment system, it is difficult to consider the actual condition of the water pump motor, and the regulation and protection of the motor are not refined enough. On the other hand, the system often reaches the established frequency directly when starting the water pump motor to supply water, which may cause problems such as excessive pressure in the subsequent pipeline and RO membrane. When starting the motor at high frequency, it may also cause an excess of water production in the RO part, and the water quality may be reduced due to the long-term non-circulation of the filtered water in the water tank.
[0004] Therefore, people need a motor regulation system and method based on artificial intelligence to solve the above problems. Summary of the Invention
[0005] The purpose of the present invention is to provide a motor regulation system and method based on artificial intelligence to solve the problems raised in the above background art.
[0006] To solve the above technical problems, the present invention provides the following technical solution: A motor regulation system based on artificial intelligence, the system includes: a motor monitoring module, a process monitoring module, a water tank monitoring module, a database, and a regulation module;
[0007] Collect real-time motor operation state data through the motor monitoring module;
[0008] Collect real-time device data and pipeline data at the rear end of the motor through the process monitoring module;
[0009] Collect real-time water level height and water quality data of the water tank at the rear end of the motor through the water tank monitoring module;
[0010] Store the current motor usage data and the usage data of the equipment at the rear end of the motor through the database;
[0011] Integrate data through the adjustment module, analyze the requirements of the water treatment system, and adjust the motor status in real time.
[0012] Further, the motor monitoring module collects the real-time frequency of the motor, collects the real-time amplitude data of the motor through a vibration sensor, and collects the real-time temperature data of the motor through a temperature sensor. The motor is the RO motor in the RO water pump at the front end of the RO membrane in the water treatment system. The motor monitoring module and the sensors are connected by a shielded control cable.
[0013] Further, the process monitoring module collects the equipment data and pipeline data at the rear end of the motor in real time through a pressure sensor. The equipment data is the pressure difference between the front and rear ends of the RO membrane, and the pipeline data is the pipeline pressure of the pipeline at the rear end of the motor.
[0014] Further, the water tank monitoring module collects the water level height of the water tank through a water level sensor and collects the water quality data of the water tank through a resistivity sensor.
[0015] Further, the motor usage data includes the maximum life and usage duration of the motor. The equipment usage data includes the optimal pressure difference affecting water quality of the RO membrane, the maximum life of the RO membrane, and the water passing duration. Adjusting the motor status includes adjusting the motor frequency and shutting down the motor.
[0016] An AI-based motor adjustment method includes the following steps:
[0017] S1: Collect the real-time motor operation status data, collect the equipment data and pipeline data at the rear end of the motor in real time, and collect the water level height and water quality data of the water tank at the rear end of the motor in real time;
[0018] S2: Monitor the water quality of the water tank, alarm when the water quality of the water tank is poor, analyze the water level height of the water tank, and calculate the change speed of the water level height;
[0019] S3: When the water level height rises, judge the motor frequency decrease requirement according to the water level rise speed. When the decreased motor frequency is lower than the minimum motor frequency, the system shuts down the motor; when the decreased motor frequency is higher than the minimum motor frequency, adjust the motor frequency;
[0020] S4: When the water level height drops, judge the motor frequency increase requirement according to the water level drop speed, comprehensively analyze the motor data, RO membrane data, and pipeline data, and calculate the motor frequency increase value; when the motor is not started, start the motor and raise it to the minimum motor frequency; when the motor has been started, raise the motor frequency according to the motor frequency increase value.
[0021] Further, in step S1, collect the operating state data of the motor: the real-time frequency of the motor is X1, the real-time amplitude data of the motor is Y1, and the real-time temperature data of the motor is Z1; collect the device data at the rear end of the motor in real time: the pressure difference between the front and rear ends of the RO membrane is P1; collect the real-time pipeline data: the pipeline pressure of the pipeline at the rear end of the motor is F1; collect the water quality data in the water tank: the water quality resistivity is R1; collect the real-time water level height in the water tank as H1; use artificial intelligence technology to collect system information and provide a database for adjusting the motor state in real time and accurately.
[0022] Further, in step S2: call the water level height before time t when collecting the real-time water level height H1, denoted as H2, and the water level change speed is V1:
[0023] V1 = (H1 - H2) / t;
[0024] where t is the set time interval for collecting the water level height. When the water quality resistivity R1 in the water tank < R, the system determines that the water quality in the water tank is poor, and R is the minimum water quality requirement required by the user; the reason for using the resistivity value to judge the water quality: Resistivity is the most important requirement for water quality judgment in pure water preparation and wastewater recycling, and is used as the judgment data for the quality of the RO membrane in the RO reverse osmosis filtration process.
[0025] Further, when V1 is greater than 0, the system determines that the water level is rising, and the system enters step S3. According to the water level change speed V1, score the motor frequency reduction requirement B. When V1 ≥ m1, the motor frequency reduction requirement score B = B1; when m1 > V1 ≥ m2, the motor frequency reduction requirement score B = B2; when V1 < m2, the motor frequency reduction requirement B = B3, B1 > B2 > B3, and calculate the motor frequency X1_1 after reducing the frequency:
[0026]
[0027] where a is the minimum frequency of the motor set by the system, m1 is the first threshold for reducing the motor frequency, and m2 is the second threshold for reducing the motor frequency. When the motor frequency X1_1 = 0, the system shuts down the motor. After adjusting the motor state, return to step S2, and calculate the water level change situation in the water tank with the current water level height as the initial water level height. Here, it is considered that starting the motor when the motor frequency is too small may cause waste of resources. When it is predicted that the motor frequency will be too small after reduction, the motor is shut down. When the water production consumption speed is slightly less than the production speed, the water level in the water tank rises slowly, and the system will reduce the motor frequency to ensure the stable operation of the system and also avoid frequent start and stop of the motor.
[0028] Further, when V1 is less than 0, the system determines that the water level is decreasing, and the system enters step S4. The demand Q for reducing the motor frequency is scored according to the water level change speed V1. When |V1| ≥ M1, the demand score Q for increasing the motor frequency is Q = Q1; when M1 > |V1| ≥ M2, the demand score Q for increasing the motor frequency is Q = Q2; when |V1| < M2, the demand Q for increasing the motor frequency is Q = Q3, where M1 is the first threshold for the system to increase the frequency, M2 is the second threshold for the system to increase the frequency, Q1 > Q2 > Q3, and the support degree k1 of the water quality of the water tank for increasing the motor frequency is calculated:
[0029] k1 = (R1 - R) * u1;
[0030] where u1 is the set weight of the water quality of the water tank on the increase of the motor frequency, and the support degree k2 of the real-time amplitude data Y1 of the motor for increasing the motor frequency is calculated:
[0031] k2 = Y2 - u2 * Y1;
[0032] where u2 is the set weight of the real-time amplitude of the motor on the increase of the motor frequency, Y2 is the maximum value of the support degree of the real-time amplitude data Y1 of the motor for increasing the motor frequency, and the support degree k3 of the maximum life n of the RO membrane and the water passing time N of the RO membrane for increasing the motor frequency is calculated:
[0033]
[0034] where u3 is the set weight of the maximum life of the RO membrane and the water passing time of the RO membrane on the increase of the motor frequency, and the inhibition degree K1 of the real-time temperature data Z1 of the motor on the increase of the motor frequency is calculated:
[0035] K1 = U1 * Z1;
[0036] where U1 is the set weight of the real-time temperature of the motor on the increase of the motor frequency, and the inhibition degree K2 of the front and rear end pressure difference P1 of the RO membrane on the increase of the motor frequency is calculated:
[0037] K2 = U2 * (P1 - P);
[0038] where U2 is the set weight of the front and rear end pressure difference of the RO membrane on the increase of the motor frequency, P is the standard pressure difference when the filtration effect of any type of RO membrane is the best, and the inhibition degree K3 of the pipeline pressure F1 at the rear end of the motor on the increase of the motor frequency is calculated:
[0039] K3 = U3 * F1;
[0040] where U3 is the set weight of the pipeline pressure at the rear end of the motor on the increase of the motor frequency. Based on the above data, the influence coefficient G1 on the increase of the motor frequency is calculated:
[0041] G1 = 1 + k1 + k2 + k3 - K1 - K2 - K3;
[0042] Calculate the motor frequency X1_2 after increasing the frequency:
[0043]
[0044] Where A is the maximum motor frequency set by the system. After adjusting the motor state, return to step S2, and calculate the change of the water tank water level with the current water level height as the initial water level height; during the process of adjusting the motor state, it avoids the damage to the RO membrane caused by excessive increase of the motor frequency, and ensures the water production quality by analyzing the pressure difference before and after the RO membrane, so as to reasonably adjust the motor state.
[0045] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: Through artificial intelligence technology, the information of the motor, RO membrane and equipment in the system can be obtained in real time. On the one hand, the present invention takes into account the change of water production, conducts refined management of the motor frequency adjustment, reduces the number of motor starts and stops when it is difficult to determine the consumption speed of the RO membrane water production due to the change of the user's water consumption at any time, and accurately adjusts the motor state to protect the motor safety. On the other hand, the present invention takes into account the state of the motor itself, considers the motor temperature and amplitude, and limits the motor frequency adjustment to protect the motor safety; on the other hand, the present invention takes into account the water tank water quality data, the optimal pressure difference of the RO membrane affecting water quality, the maximum life of the RO membrane and the water passing time of the RO membrane, calculates the motor frequency increase value based on the motor frequency increase demand, enhances the linkage of the entire system, provides more accurate data guarantee for adjusting the motor state, and ensures the safety and accuracy of adjusting the motor state.

The motor is the RO motor in the RO water pump at the front end of the RO membrane in the water treatment system. The motor monitoring module is connected to the sensor through a shielded control cable.
[0057] The process monitoring module collects real-time equipment data and pipeline data at the rear end of the motor through a pressure sensor. The equipment data is the pressure difference between the front and rear ends of the RO membrane, and the pipeline data is the pipeline pressure of the pipeline at the rear end of the motor.

Adjusting the motor status includes adjusting the motor frequency and shutting down the motor.
[0060] An artificial intelligence-based motor regulation method includes the following steps:
[0061] S1: Collect real-time motor operation status data, collect real-time equipment data and pipeline data at the rear end of the motor, and collect the water level height and water quality data of the water tank at the rear end of the motor;
[0062] S2: Monitor the water quality of the water tank, alarm when the water quality of the water tank is poor, analyze the water level height of the water tank, and calculate the change speed of the water level height;
[0063] S3: When the water level height rises, judge the demand for motor frequency decrease according to the rising speed of the water level. When the motor frequency after the decrease is lower than the minimum motor frequency, the system turns off the motor; when the motor frequency after the decrease is higher than the minimum motor frequency, adjust the motor frequency.
[0064] S4: When the water level height drops, judge the demand for motor frequency increase according to the dropping speed of the water level, comprehensively analyze the motor data, RO membrane data and pipeline data, and calculate the motor frequency increase value; when the motor is not turned on, then turn on the motor and raise it to the minimum motor frequency; when the motor is already turned on, then raise the motor frequency according to the motor frequency increase value.
[0065] In step S1, collect the motor operation state data: the real-time motor frequency is X1, the real-time motor amplitude data is Y1, and the real-time temperature data of the motor is Z1; collect the equipment data at the rear end of the motor in real time: the pressure difference between the front and rear ends of the RO membrane is P1; collect the real-time pipeline data: the pipeline pressure of the pipeline at the rear end of the motor is F1; collect the water quality data in the water tank: the water quality resistivity is R1; collect the real-time water level height in the water tank as H1.

[0067] V1 = (H1 - H2) / t;
[0068] Where t is the set time interval for collecting the water level height. When the water quality resistivity R1 in the water tank < R, the system judges that the water quality in the water tank is poor, and R is the minimum water quality requirement required by the user.
[0069] When V1 is greater than 0, the system judges that the water level rises, and the system enters step S3. Score the motor frequency decrease demand B according to the water level change speed V1. When V1 ≥ m1, the motor frequency decrease demand score B = B1; when m1 > V1 ≥ m2, the motor frequency decrease demand score B = B2; when V1 < m2, the motor frequency decrease demand B = B3, B1 > B2 > B3, and calculate the motor frequency X1_1 after reducing the frequency.
[0070]
[0071] Where a is the minimum frequency of the motor set by the system, m1 is the first threshold for motor frequency reduction, m2 is the second threshold for motor frequency reduction. When the motor frequency X1_1 = 0, the system turns off the motor. After adjusting the motor state, return to step S2, and calculate the water level change situation in the water tank with the current water level height as the initial water level height.
[0072] When V1 is less than 0, the system determines that the water level is decreasing, and the system enters step S4. The demand Q for reducing the motor frequency is scored according to the water level change speed V1. When |V1| ≥ M1, the demand score Q for increasing the motor frequency is Q = Q1; when M1 > |V1| ≥ M2, the demand score Q for increasing the motor frequency is Q = Q2; when |V1| < M2, the demand Q for increasing the motor frequency is Q = Q3, where M1 is the first threshold for the system to increase the frequency, M2 is the second threshold for the system to increase the frequency, Q1 > Q2 > Q3, and the support degree k1 of the water quality of the water tank for increasing the motor frequency is calculated:

[0084] where U3 is the set weight of the pipeline pressure at the rear end of the motor on the increase of the motor frequency. Based on the above data, the influence coefficient G1 on the increase of the motor frequency is calculated:
[0085] G1 = 1 + k1 + k2 + k3 - K1 - K2 - K3;
[0086] Calculate the motor frequency X after increasing the frequency 1_2 :

[0088] where A is the maximum motor frequency set by the system. After adjusting the motor state, return to step S2, and calculate the change in the water tank level with the current water level height as the initial water level height.
[0089] Embodiment 1: When the system monitors that V1 = -5 and V1 < 0, the system determines that the water level is decreasing. The system enters step S4 and evaluates the motor frequency reduction requirement Q based on the water level change speed V1. When |V1| ≥ M1, the motor frequency increase requirement score Q = Q1; when M1 > |V1| ≥ M2, the motor frequency increase requirement score Q = Q2; when |V1| < M2, the motor frequency increase requirement Q = Q3, where M1 is the first threshold for the system to increase the frequency, M2 is the second threshold for the system to increase the frequency, where M1 = 15, M2 = 10, M1 = 5. In summary, the motor frequency reduction requirement Q = 10, and calculate the support degree k1 of the water tank water quality for the motor to increase the frequency:

[0097] where U1 = 0.005 is the weight of the motor real-time temperature on the motor frequency increase, and calculate the inhibition degree K2 of the pressure difference P1 between the front and rear ends of the RO membrane on the motor frequency increase:
[0098] K2 = U2 * (P1 - P) = 0.5 * (0.6 - 0.3) = 0.15;
[0099] Where U2 = 0.5 is the weight of the pressure difference between the front and rear ends of the RO membrane on the motor's increased frequency, and P is the standard pressure difference when the filtration effect of any type of RO membrane is the best. Calculate the degree of inhibition K3 of the pipeline pressure F1 at the rear end of the motor on the motor's increased frequency:
[0100] K3 = U3 * F1 = 0.5 * 0.8 = 0.4;
[0101] Where U1 = 0.3 is the weight of the pipeline pressure at the rear end of the motor on the motor's increased frequency. Calculate the motor's increased frequency G1:
[0102] G1 = 1 + k1 + k2 + k3 - K1 - K2 - K3 = 0.8;
[0103] Substitute and calculate the motor frequency X1_2 after the increased frequency:
[0104]
[0105] Obtain X 1_2 = X1 + 8. After adjusting the motor state, return to step S2, and calculate the change in the water tank level with the current water level height as the initial water level height.
