[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] Embodiment 1

[0031] This embodiment monitors the drive control in parts to ensure the stability of the drive control. Figure 1 As shown, a distributed vibration membrane bioreactor double-side servo electric cylinder drive control system includes a drive control center, wherein the drive control center is communicatively connected to a motor leveling control unit, a drive control monitoring unit, and an electric cylinder control analysis unit;

[0032] During the operation of the membrane bioreactor, the drive control center generates a motor leveling control signal and sends the motor leveling control signal to the motor leveling control unit. After receiving the motor leveling control signal, the motor leveling control unit performs motor regulation and control on the driving process. The motor leveling control is used to ensure that both sides of the motor are in a balanced state, so that the motors on both sides are in a balanced state. As long as synchronous operation is ensured, it can be ensured that there is no pulling at both ends during the movement process, so as to improve the efficiency of the motor drive energy supply;

[0033] Obtain the deviation value of the motor speed control amount corresponding to the peripheral external force processed by the motors at different positions when the motors on both sides are running synchronously, where the external force is represented by the force generated by the outside world at the position of the motor, such as friction, etc.; and mark the deviation value of the motor speed control amount corresponding to the peripheral external force processed by the motors at different positions when the motors on both sides are running synchronously as PCZ; obtain the cumulative value of the electrical control displacement deviation during the synchronous operation stage of the motors on both sides, and mark the cumulative value of the electrical control displacement deviation during the synchronous operation stage of the motors on both sides as LJZ; obtain the real-time distance deviation peak value corresponding to the unbalanced position caused by the internal mechanical gap of the motors during the operation stage of the motors on both sides, and mark the real-time distance deviation peak value corresponding to the unbalanced position caused by the internal mechanical gap of the motors during the operation stage of the motors on both sides as JLF;

[0034] The above collected information is uniformly marked as motor leveling information, and substituted into the formula to obtain the motor leveling control coefficient during the motor synchronous operation process. The formula is: Where X is the motor leveling control coefficient, vn1, vn2 and vn3 are preset proportional coefficients, and α is the error correction factor, which is 0.978;

[0035] Compare the motor leveling control coefficient with the motor leveling control coefficient threshold during motor synchronous operation:

[0036] If the motor leveling control coefficient exceeds the motor leveling control coefficient threshold during the synchronous operation of the motor, it is inferred that the control of the motors on both sides is abnormal, and an asynchronous signal is generated and sent to the drive control center. After receiving the asynchronous signal, the drive control center performs synchronous manual control on the motors on both sides and ensures synchronous operation;

[0037] If the motor leveling control coefficient does not exceed the motor leveling control coefficient threshold during the motor synchronous operation, it is inferred that the motor regulation and control on both sides is normal, and a synchronization signal is generated and sent to the drive control center;

[0038] At the same time, a drive control monitoring signal is generated and sent to the drive control monitoring unit. After receiving the drive control monitoring signal, the drive control monitoring unit monitors and analyzes the motor operation drive to determine whether the motor operation adjustment performance of the driver control during the motor operation stage meets the actual needs, thereby ensuring the stability of the driver performance and improving the motor operation accuracy, avoiding the decrease in reactor operation efficiency caused by abnormal drive control, and failing to give full play to the working efficiency of the reactor and reducing the feasibility of sewage treatment. In the prior art, MPSN-040-AS intelligent servo is often used as a controller and driver to control the servo motor on one side of the electric cylinder and send pulses to control the general servo driver of the motor on the other side of the electric cylinder.

[0039] The deviation value between the preset speed control amount of the motor speed controlled by the driver and the actual amount of the motor actual operating speed in the stage where the driver and the motor cooperate to run is obtained, and the non-overlapping duration of the period when the driver adjusts and controls the motor operating parameters and the period when the motor receives the adjusted operating parameters are changed in the stage where the driver and the motor cooperate to run is obtained, and the deviation value between the preset speed control amount of the motor speed controlled by the driver and the actual amount of the motor actual operating speed in the stage where the driver and the motor cooperate to run, and the non-overlapping duration of the period when the driver adjusts and controls the motor operating parameters and the period when the motor receives the adjusted operating parameters are changed in the stage where the driver and the motor cooperate to run are marked as control deviation information and control delay information, respectively, and compared with the speed deviation value threshold and the non-overlapping duration threshold, respectively:

[0040] If the deviation between the preset speed control amount of the motor speed controlled by the driver and the actual amount of the motor's actual operating speed during the stage of coordinated operation of the driver and the motor exceeds the speed deviation value threshold, or the non-overlapping time of the period of the driver adjusting and controlling the motor's operating parameters and the period of execution of the motor's adjusted operating parameters during the stage of coordinated operation of the driver and the motor exceeds the non-overlapping time threshold, it is inferred that the drive control monitoring during the stage of coordinated operation of the driver and the motor is abnormal, a drive control abnormality signal is generated and sent to the drive control center, and after receiving the drive control abnormality signal, the drive control center detects the control performance of the driver and the command execution performance of the motor, and at the same time analyzes the timeliness of the command communication between the driver and the motor, and makes adjustments when the timeliness is abnormal;

[0041] If the deviation between the preset speed control amount of the motor speed controlled by the driver and the actual amount of the motor actual operating speed during the stage of coordinated operation of the driver and the motor does not exceed the speed deviation value threshold, and the non-overlapping time of the period of the driver adjusting and controlling the motor operating parameters during the stage of coordinated operation of the driver and the motor and the period of executing the motor changing the operating parameters after receiving the adjustment during the stage of coordinated operation of the driver and the motor does not exceed the non-overlapping time threshold, it is inferred that the drive control detection during the stage of coordinated operation of the driver and the motor is normal, a drive control normal signal is generated and the drive control normal signal is sent to the drive control center;

[0042] At the same time, an electric cylinder control analysis signal is generated and sent to the electric cylinder control analysis unit. After receiving the electric cylinder control analysis signal, the electric cylinder control analysis unit performs operation control analysis on the electric cylinder where the motor is located, and infers whether the efficiency of the coordinated operation of the electric cylinder and the motor during the operation of the reactor meets the actual demand, thereby improving the control and adjustment performance of the electric cylinder, making the position control of the motor more accurate, and the combination of the servo motor and the electric cylinder can achieve high-precision position and speed control, meeting the application occasions with high requirements for motion accuracy;

[0043] The buffer time corresponding to the conversion of rotary motion to linear motion when the electric cylinder control matches the motor trajectory during the operation of the reactor is obtained, and the real-time reciprocating floating maximum span value of the motor position control accuracy during the operation type change process is obtained. The buffer time corresponding to the conversion of rotary motion to linear motion when the electric cylinder control matches the motor trajectory during the operation of the reactor and the real-time reciprocating floating maximum span value of the motor position control accuracy during the operation type change process are marked as electric cylinder adjustment data and electric cylinder position data, respectively, and compared with the operation adjustment buffer time threshold and the floating maximum span value threshold, respectively:

[0044] If the buffer time for converting the corresponding rotary motion into linear motion when the electric cylinder control matches the motor trajectory during the operation of the reactor exceeds the operation adjustment buffer time threshold, or the real-time reciprocating floating maximum span value of the motor position control accuracy during the operation type change exceeds the floating maximum span value threshold, it is inferred that the electric cylinder control analysis during the operation of the reactor is abnormal, and an electric cylinder control inefficiency signal is generated and sent to the drive control center. After receiving the electric cylinder control inefficiency signal, the drive control center performs equipment detection on the electric cylinder and evaluates the transmission of the electric cylinder adjustment command to ensure that the adjustment command is generated and sent normally;

[0045] If the buffer time corresponding to the conversion of rotary motion to linear motion when the electric cylinder control matches the motor trajectory during the operation of the reactor does not exceed the operation adjustment buffer time threshold, and the real-time reciprocating floating maximum span value of the motor position control accuracy during the operation type conversion process does not exceed the floating maximum span value threshold, it is inferred that the electric cylinder control analysis during the operation of the reactor is normal, and an electric cylinder control high-efficiency signal is generated and sent to the drive control center;

[0046] Embodiment 2

[0047] After the previous embodiment controls and detects each driving component, this embodiment adds a closed-loop control analysis unit on the basis of the previous embodiment. Figure 2 As shown, the drive control center is communicatively connected with a closed-loop control analysis unit;

[0048] After the control detection of each driving component is qualified, the driving control center generates a closed-loop control analysis signal and sends the closed-loop control analysis signal to the closed-loop control analysis unit. After receiving the closed-loop control analysis signal, the closed-loop control analysis unit performs a closed-loop control analysis on the driving process, and infers whether the entire current driving process is qualified based on the real-time detection of the sensor and the real-time centralized control of the controller. A closed loop is formed from detection to driving and then to detection, ensuring the efficient execution of the driving process while monitoring the driving process in real time. When deviations occur in the monitoring, timely adjustments are made to ensure the overall operational stability of the reactor;

[0049] The distance deviation value of the motor position monitored by the sensor during the operation cycle of the reactor and the delay value of the preset time length of the motor movement controlled by the controller at the current position are obtained. After dedimensionalization processing through numerical acquisition, the sum calculation is performed and the sum value is marked as closed-loop control information. At the same time, the increase speed of the gap time length of the non-overlapping period corresponding to the sensor monitoring period and the controller adjustment period during the operation cycle of the reactor is obtained, and the increase speed of the gap time length of the non-overlapping period corresponding to the sensor monitoring period and the controller adjustment period during the operation cycle of the reactor is marked as closed-loop risk information, and compared with the numerical sum threshold and the time increase speed threshold respectively:

[0050] If the closed-loop control information exceeds the value and threshold, or the increase rate of the gap duration of the non-overlapping periods corresponding to the sensor monitoring period and the controller adjustment period in the reactor operation cycle exceeds the time increase rate threshold, it is inferred that the closed-loop control analysis in the current reactor operation cycle is abnormal, and a cycle interruption high-risk signal is generated and sent to the drive control center. After receiving the cycle interruption high-risk signal, the drive control center shortens the current reactor operation cycle and reduces the task volume, and conducts operation hardware coordination monitoring in a timely manner;

[0051] If the closed-loop control information does not exceed the value and threshold, and the increase rate of the gap duration of the non-overlapping periods corresponding to the sensor monitoring period and the controller adjustment period in the reactor operation cycle does not exceed the time increase rate threshold, it is inferred that the closed-loop control analysis in the current reactor operation cycle is normal, and a cycle normal signal is generated and sent to the drive control center;

[0052] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by technicians in this field according to actual conditions;

[0053] When the present invention is in use, the motor leveling control unit is used to perform motor regulation and control on the driving process, collect motor leveling information, and substitute it into the formula to obtain the motor leveling control coefficient, and infer whether the motor regulation is normal according to the coefficient threshold comparison. If not, artificial active regulation is performed. If yes, the motor operation drive monitoring is performed through the drive control monitoring unit; the drive control monitoring unit is used to obtain control deviation information and control delay information, and infer whether the drive control monitoring is normal according to information comparison.
