[0026] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.
[0027] The present application embodiment provides a guide vane angle compensation control method, such as Figure 1 As shown, the method includes:
[0028] 101. Obtain a target angle and a starting angle of a guide vane corresponding to a target compressor, compare the target angle with the starting angle, and obtain a comparison result. The target angle is used to indicate a rotation angle of the guide vane, and the starting angle is used to indicate a current position of the guide vane.
[0029] In the embodiment of the present application, considering that the working performance of each compressor is different, the method is provided with a background terminal, and relevant staff can control the working parameters of the target compressor at the background terminal, and then adjust the working state of the target compressor.
[0030] Specifically, this method is applied to the control system of the compressor. During the actual operation, the relevant staff can select the target compressor to perform this operation through the background terminal, and input the target angle of the guide vane rotation to the target compressor. Furthermore, after receiving the target angle, the control system calls the guide vane measurement device to measure the inlet guide vane, and obtains the current angle of the guide vane as the starting angle. Finally, the control system compares the target angle with the starting angle in the numerical dimension, and obtains a comparison result indicating the size relationship between the target angle and the starting angle.
[0031] The above steps determine the size relationship between the target angle and the starting angle by obtaining the target angle and the starting angle, and then determine whether the target angle needs angle compensation. If the target angle is smaller than the starting angle, continue to execute the following steps to complete the angle compensation of the inlet guide vane of the target compressor.
[0032] 102. When the comparison result indicates that the target angle is smaller than the starting angle, query the target correction angle in the correction angle library corresponding to the target compressor.
[0033] In an embodiment of the present application, when the system identifies that the comparison result indicates that the target angle is less than the starting angle, the control system needs to enter the reverse control process to perform angle compensation and lock the reverse control state to eliminate the error between the actual angle and the feedback angle. Specifically, the target correction angle is queried in the correction angle library corresponding to the target compressor. It should be noted that, considering the different equipment performance of each compressor, the angle error generated is also different. Therefore, different compressors correspond to different correction angle libraries. Furthermore, the correction indicators stored in the correction angle library can be obtained through trial operation. In other words, in the actual application process, the relevant staff can input the target angle for each compressor of multiple compressors multiple times, measure the actual angle of the inlet guide vane, and query the feedback angle returned by the console, that is, the feedback angle, and then realize the generation of corresponding correction indicators through the error between the actual angle and the feedback angle.
[0034] When the target angle is less than the starting angle, the above steps enter the reverse control process to perform angle compensation, and by extracting the target correction angle stored in the correction angle library corresponding to the current target compressor, a data basis is provided for subsequent angle compensation of the target angle.
[0035] 103. Based on the target correction angle, the actual angle is calculated and sent to the control console, so that the control console drives the guide vane to rotate according to the actual angle.
[0036] In an embodiment of the present application, the control system calculates the actual rotation angle of the inlet guide vane according to the target correction angle obtained by the query, so that the control console drives the guide vane to rotate according to the actual angle, and sends a first feedback signal to the control system after the guide vane reaches the specified position. Among them, the control console is used to drive the inlet guide vane to rotate to reach the specified position. The control system calculates the actual angle and sends it to the control console to change the actual rotation angle of the inlet guide vane, thereby achieving angle compensation for the target angle, eliminating the angle deviation between the target angle and the feedback angle in the dimension of the guide vane rotation position, improving the stability of the guide vane position, and meeting the stable operation of the unit load.
[0037] 104. Receive a first feedback signal sent by the console, convert the first feedback signal into a first feedback angle, and add the first feedback angle to the target correction angle for display.
[0038] In the embodiment of the present application, the control system receives the first feedback signal sent by the console, and converts the 4-20mA first feedback signal into a first feedback angle. Finally, the sum of the first feedback angle and the target correction angle is calculated, angle compensation is performed, and the compensated sum is sent to the background terminal for display.
[0039] By adding the first feedback angle to the target correction angle and displaying it as the true feedback angle, the feedback angle is compensated, and the angle deviation between the target angle and the feedback angle is eliminated from the dimension of the feedback angle, thereby improving the stability of the guide vane position and meeting the stable operation of the unit load.
[0040] The method provided in the embodiment of the present application first obtains the target angle and starting angle of the guide vane corresponding to the target compressor, compares the target angle with the starting angle, and obtains the comparison result. When the comparison result indicates that the target angle is less than the starting angle, the target correction angle is queried in the correction angle library corresponding to the target compressor. Next, based on the target correction angle, the actual angle is calculated and sent to the console so that the console drives the guide vane to rotate according to the actual angle. Finally, the first feedback signal sent by the console is received, the first feedback signal is converted into a first feedback angle, and the first feedback angle is added to the target correction angle for display. The present invention determines whether the target angle needs to be compensated by angle by judging the size relationship between the target angle and the starting angle, and then when angle compensation is required, the corresponding target correction angle is queried, and the actual angle of the guide vane rotation is calculated, so that the feedback angle returned by the console after rotating the guide vane according to the actual angle is added to the target correction angle to be displayed as the feedback angle, so as to eliminate the angle deviation between the target angle and the feedback angle through angle compensation, improve the stability of the guide vane position, and meet the stable operation of the unit load.
[0041] The present application embodiment provides a guide vane angle compensation control method, such as Figure 2 As shown, the method includes:
[0042] 201. In response to receiving a target angle corresponding to a target compressor, perform a pre-operation detection on the target compressor.
[0043] Specifically, the control system checks the guide vane wiring and interlocking signal of the guide vane in response to receiving the target angle corresponding to the target compressor. It should be noted that the guide vane wiring at least includes the live wire, the neutral wire, the ground wire of the power supply terminal and the local control panel wiring of the guide vane, and the interlocking signal at least includes the temperature signal, the pressure signal, the vibration signal, the displacement signal, and the emergency stop signal. Next, check whether the oil station allows the start-up conditions to be met, wherein the allowable conditions include normal sealing isolation gas, normal mailbox temperature, normal mailbox liquid level, etc. Further, when the guide vane wiring and the interlocking signal meet the corresponding indicators respectively, and the oil station meets the allowable start-up conditions, start the lubricating oil pump and the hydraulic power oil pump, wherein the lubricating oil pump is used to ensure that the pressure value of the peripheral system of the target compressor is at the normal pressure value, and the hydraulic power oil pump is the driving medium of the guide vane, which is used to ensure that the hydraulic pressure value of the power oil of the target compressor is at the normal hydraulic pressure value. Finally, the pressure value and the hydraulic pressure value are detected, and when the pressure value hits the normal pressure value and the hydraulic pressure value hits the normal hydraulic pressure value, a reminder message indicating that the preparation is completed is sent to the console. In actual application, the guide vanes will be driven to rotate only after the console receives a reminder message indicating that the preparation is complete and the actual angle.
[0044] In addition, considering that the equipment performance of each compressor is different, the angle error generated is also different, and different compressors correspond to different correction angle libraries, among which the correction indicators stored in the correction angle library can be obtained through trial operation. In the actual application process, relevant staff can input the target angle for each of the multiple compressors multiple times, measure the actual angle of the inlet guide vane, and query the feedback angle returned by the console, that is, the feedback angle. Furthermore, the corresponding correction index is generated by the error between the actual angle and the feedback angle.
[0045] By executing the above steps, the target compressor is inspected before operation. When the target compressor is in normal operation, a reminder message indicating that the preparation is complete can be sent to the control console, so that the control console drives the guide vanes to rotate normally after receiving the reminder message and the actual rotation angle, thereby ensuring the stable operation of the compressor.
[0046] 202. Measure the angle of the current guide vane as the starting angle, compare the numerical values of the target angle and the starting angle, and obtain a comparison result indicating the size relationship between the target angle and the starting angle. When the comparison result indicates that the target angle is smaller than the starting angle, execute the following step 203; when the comparison result indicates that the target angle is larger than the starting angle, execute the following step 206.
[0047] In an embodiment of the present application, relevant staff can select the target compressor to perform this operation through the background terminal, and input the target angle of the guide vane rotation to the target compressor. Furthermore, after receiving the target angle, the control system calls the guide vane measuring device to measure the inlet guide vane, and obtains the current angle of the guide vane as the starting angle. Finally, the control system compares the target angle with the starting angle in the numerical dimension to obtain a comparison result indicating the size relationship between the target angle and the starting angle. When the comparison result indicates that the target angle is less than the starting angle, the target device number corresponding to the target compressor is queried, and all correction indicators stored in the correction angle library are read, that is, the following step 203 is executed. When the comparison result indicates that the target angle is greater than the starting angle, the target angle is converted into a second angle signal of 4-20mA and sent to the control station, that is, the following step 206 is executed.
[0048] By comparing the size relationship between the target angle and the starting angle, it is determined whether the target angle needs angle compensation. If the target angle is smaller than the starting angle, continue to execute the following steps 203 to 205 to enter the reverse control process to complete the angle compensation of the inlet guide vane of the target compressor.
[0049] 203. When the comparison result indicates that the target angle is smaller than the starting angle, query the target correction angle in the correction angle library corresponding to the target compressor.
[0050] In the embodiment of the present application, different compressors correspond to different device numbers. Therefore, the control system can identify all correction indicators stored in the correction database according to the target device number corresponding to the target compressor, and find the target correction angle that hits the target angle. The corresponding target correction angle can be found more accurately through the device number, thereby improving the accuracy of angle compensation.
[0051] Specifically, the control system first queries the target device number corresponding to the target compressor, and reads all the correction indicators stored in the correction angle library. Further, based on natural language processing technology, all the device tags corresponding to all the correction indicators are identified, and multiple specified correction indicators whose tag contents are consistent with the target device number are extracted from all the correction indicators. In the actual application process, since the correction indicators of all compressors are stored in the correction angle library, the control system will add a device tag for indicating the corresponding compressor number to the correction indicator when storing it for easy distinction. Further, the control system can find multiple specified correction indicators whose tag contents are consistent with the target device number in all the correction indicators based on the target device number corresponding to the target compressor. It should be noted that each correction indicator in the multiple specified correction indicators consists of a correction interval and a correction angle. Finally, the difference between the target angle and the starting angle is calculated, and the absolute value of the difference is calculated. The target correction interval hit by the absolute value is queried in the multiple specified correction indicators, and the correction angle corresponding to the target correction interval is used as the target correction angle, thereby realizing the corresponding target correction angle based on the target angle and the starting angle, and improving the accuracy of angle compensation.
[0052] 204. Based on the target correction angle, the difference between the target angle and the target correction angle is calculated as the actual angle, the actual angle is converted into a 4-20mA first angle signal, and sent to the control station
[0053] In an embodiment of the present application, the system calculates the actual angle that the guide vane should rotate based on the target correction angle obtained by the query, so that the console drives the guide vane to rotate according to the actual angle. Specifically, the difference between the target angle and the target correction angle is calculated as the actual angle, the actual angle is converted into a first angle signal of 4-20mA, and sent to the control station. Further, the control station drives the guide vane to rotate according to the first angle signal, and after the guide vane reaches the position indicated by the first angle signal, a first feedback signal of 4-20mA is sent to the control system. For example, the target correction angle is 2°, the target angle is 20°, the difference between the target angle and the target correction angle is calculated to be 18°, and 18° is converted as the actual angle into a first angle signal of 4-20mA and sent to the control station.
[0054] By calculating the actual angle and sending it to the control console, the actual rotation angle of the inlet guide vane can be changed, and then the target angle can be compensated. The angle deviation between the target angle and the feedback angle can be eliminated in the dimension of rotation position, thereby improving the stability of the guide vane position and meeting the stable operation of the unit load.
[0055] 205. Receive a first feedback signal sent by the console, convert the first feedback signal into a first feedback angle, and add the first feedback angle to the target correction angle for display.
[0056] In an embodiment of the present application, the control system receives the first feedback signal sent by the console, converts the 4-20mA first feedback signal into a first feedback angle, and finally calculates the sum of the first feedback angle and the target correction angle, performs angle compensation, and sends the compensated sum to the background terminal for display. For example, the target correction angle is 2°, and the first feedback angle converted by the first feedback signal returned by the console is 18°. The target correction angle of 2° is added to the first feedback angle of 18° to obtain a feedback angle of 20°, and 20° is sent to the background terminal for display.
[0057] Through the above steps, the first feedback angle is added to the target correction angle and displayed as the real feedback angle, so as to compensate for the feedback angle, eliminate the angle deviation between the target angle and the feedback angle from the dimension of the feedback angle, improve the stability of the guide vane position, and meet the stable operation of the unit load.
[0058] 206. When the comparison result indicates that the target angle is greater than the starting angle, the target angle is converted into a second angle signal of 4-20 mA and sent to the control station.
[0059] In an embodiment of the present application, when the comparison result indicates that the target angle is greater than the starting angle, the control system enters a forward control process and only needs to convert the target angle into a second angle signal of 4-20mA and send it to the control station so that the control station drives the guide vane to rotate according to the second angle signal, and after the guide vane reaches the position indicated by the second angle signal, sends a second feedback signal of 4-20mA to the control system, thereby eliminating the angle deviation between the target angle and the feedback angle and improving the stability of the guide vane position.
[0060] 207. Receive a second feedback signal sent by the control station, and convert the second feedback signal into a second feedback angle for display.
[0061] In an embodiment of the present application, the control system receives a second feedback signal sent by the console, converts the second feedback signal of 4-20mA into a second feedback angle, and sends it to the background terminal for display.
[0062] In addition, during the guide vane adjustment process, when the control system detects that the target compressor has a system interlock or normal shutdown, the guide vane is adjusted to the initial position. It should be noted that in the actual operation process, the initial position can be an angle preset by relevant staff, such as 0°, etc. This application does not specifically limit the angle of the initial position. Furthermore, in the process of driving the guide vane to rotate, when the control system detects alarm information including the disappearance of the power oil signal, the triggering of a low alarm, the triggering of a high alarm, etc., the inlet guide vane is locked to keep it in the current position.
[0063] The method provided in the embodiment of the present application first obtains the target angle and starting angle of the guide vane corresponding to the target compressor, compares the target angle with the starting angle, and obtains the comparison result. When the comparison result indicates that the target angle is less than the starting angle, the target correction angle is queried in the correction angle library corresponding to the target compressor. Next, based on the target correction angle, the actual angle is calculated and sent to the console so that the console drives the guide vane to rotate according to the actual angle. Finally, the first feedback signal sent by the console is received, the first feedback signal is converted into a first feedback angle, and the first feedback angle is added to the target correction angle for display. The present invention determines whether the target angle needs to be compensated by angle by judging the size relationship between the target angle and the starting angle, and then when angle compensation is required, the corresponding target correction angle is queried, and the actual angle of the guide vane rotation is calculated, so that the feedback angle returned by the console after rotating the guide vane according to the actual angle is added to the target correction angle to be displayed as the feedback angle, so as to eliminate the angle deviation between the target angle and the feedback angle through angle compensation, improve the stability of the guide vane position, and meet the stable operation of the unit load.

The present invention determines whether the target angle needs to be compensated by angle by judging the size relationship between the target angle and the starting angle, and then when angle compensation is required, the corresponding target correction angle is queried, and the actual angle of the guide vane rotation is calculated, so that the feedback angle returned by the console after rotating the guide vane according to the actual angle is added to the target correction angle to be displayed as the feedback angle, so as to eliminate the angle deviation between the target angle and the feedback angle through angle compensation, improve the stability of the guide vane position, and meet the stable operation of the unit load.
