In addition, the intelligent terminal can also realize functions/buttons such as rotor positioning, damage marking, return marking, current blade number displaying and the like. The intelligent terminal realizes the functions through programming, and is specific:
(1) Initialization of
The initialization operation includes reading and writing specific registers, determining an origin position and a current position, and calculating a relative distance between the current position and the origin position, wherein the distance is used for rotation control and blade mark calculation. In addition to clicking the button, data is written into registers Pn068, pn069, pn002, pn128, respectively. Since the current program applies the position mode of the servo motor, after the Cmode bit of Pn068 is set to 1, i.e. controlled by the CN1 port communication, the selection of the working mode of the servo motor is jointly selected by Pn002 and Pn070, where the value in the Pn002 register is set to 4, i.e. the position/torque mode, and then the Cmode bit of Pn070 is set to 1, i.e. the position mode. Pn128 is the internal position command 0 running speed, and the internal position command is selected by two BITs, pos2 (BIT 9) and Pos1 (BIT 8) of Pn071, both set to 1 (OFF) in this embodiment, so the corresponding internal position command 0 is executed by the "initialize" button.
(2) Start to rotate and reverse
A) Writing the Pn071 register, leaving the other BITs of Pn071 unchanged, only requires pstop (BIT 11) to be set to 0 and ptriger (BIT 10) to be set to 1, which is to first pause the motor to allow the motor to be started later.
B) The pulse command is written to the Pn120 and Pn121 registers, where the number of pulses is just one revolution of the high voltage rotor of the engine (clockwise as viewed from the intake direction), where there are tens of thousands of pulses in the Pn120 registers, and the number of pulses in Pn121 is less than ten thousands of pulses, and since the motor is just reversing when the engine is rotating forward, the number of pulses input to Pn120 and Pn121 is negative. For the motor, 10000 pulse motors run for one circle, a speed reducer is also connected outside the motor, the transmission ratio of the motor through the speed reducer is 50:1, meanwhile, the motor is arranged on a hand-operated transmission seat, the transmission ratio of the hand-operated transmission seat to a high-voltage rotor of the engine is I, then the number of pulses passing through the high-voltage rotor for one circle is 500000/I, the input pulse command is-500000/I because the motor is reversed, the input pulse command is a complement code when negative numbers are written into a register, the value written into Pn120 is 65536- (int) (500000/I)/10000, and the value written into the high-low positions of Pn120 is (65536- (int) (500000/I)/10000)/256, (65536- (int) (500000/I)/10000)%). Fewer than ten thousand pulses are written into the Pn121 register, and similarly, the high and low values written into the Pn121 register are (65536- (int) (500000/I)% 10000)/256, (65536- (int) (500000/I)% 10000)% 256, in this order.
C) The Pn098 register is written, the Pn098 register is the numerator 1 of the pulse electronic gear ratio, which pulse electronic gear ratio is selected is determined by Gn2 (BIT 1) and Gn1 (BIT 0) in the Pn071 register, the denominator of the pulse electronic gear ratio is determined by the Pn102 register, and the configuration parameter writing button is set in the program because the register needs to be permanently written to be effective, and the actual rotation speed of the motor= (the value in Pn098 is the value in Pn 128)/the value in Pn102 is set in the program. The latter acceleration and deceleration is also achieved by adjusting the molecular of the electronic gear ratio.
D) A Pn070 register is written with the upper eight BITs set to 127 and the lower eight BITs set to 190, at which time Cmode BITs (BIT 13) are set to 1 (OFF), i.e., to position mode, and Son BITs (BIT 0) are set to 0 (ON) to enable, i.e., energize, the motor.
E) The Pn071 register is written, and the written value is kept unchanged while the other bits are changed to be pstop and ptriger, and the two bits are respectively set to be 1 and 0 to cancel the pause instruction to trigger the motor to rotate.
(3) Stop of
The Pn070 register is written firstly, other bits are kept unchanged, and the Son bit is set to 1 only to enable the motor, so that the motor stops working.
(4) Acceleration and deceleration
In the actual hole detection, the rotation speed of the high-voltage rotor of the engine is sometimes required to be regulated, so that when an 'acceleration', 'deceleration' button is arranged and the 'acceleration' or 'deceleration' button is clicked, the value in a molecular Pn098 register of the electronic gear ratio is correspondingly increased or decreased, and the actual rotation speed of the motor is also changed.
(5) Click and reverse click
The reason for designing these two buttons is: when hole detection is performed, sometimes the angle of the blade or the position of the rotor is not very convenient, and in order to adjust the angle or the position of the rotor to a proper position, the engine rotor needs to be slightly adjusted, and the positive micro-rotation and the negative micro-rotation are respectively the positive rotation and the reverse rotation of the engine by 2 degrees. The specific algorithm is as follows: the number of pulses of one rotation of the high-voltage rotor of the engine (no forward and backward rotation is required) is 500000/I, the corresponding number of pulses is (500000/I)/360 when the walk angle is 1 degree, the corresponding number of pulses when the walk angle is 2 degrees is (500000/I)/180, and 35000/(9*I) is simplified, because the number of pulses can be certainly less than ten thousand when the walk angle is 2 degrees, only the number of pulses corresponding to 2 degrees can be written into the Pn121 register. The motor is reversed when in forward micro-rotation, so that the input pulse number is-3500/(9*I), and the negative number is written into the register and is input in the form of complementary code, so that the high-order and low-order values written into the Pn121 register are (65536- (int) (35000/(9*I)))/256, (65536- (int) (35000/(9*I)))% 256 respectively. The motor rotates positively when in negative micro-rotation, and the high and low bits of the Pn121 register are respectively input with (int) (35000/(9*I))/256, (int) (35000/(9*I))% 256. After the pulse value is written, the motor is triggered to operate according to a new pulse command, and the trigger is effective when the motor is in a pause state, so that in order to ensure that the trigger is effective, the high eight bits of the Pn071 register are written to be 7, the low eight bits are written to be 255, the motor is in the pause state, then the high eight bits of the Pn071 register are written to be 11, and the low eight bits are written to be 255, so that the motor is triggered to operate according to the new pulse command.
(6) Pause
The pause function is to meet the actual hole inspection needs, such as sometimes by temporarily stopping the rotation of the engine rotor for scrutiny during the inspection process. Clicking the "pause" button, the program writes the Pn071 register internally to stop rotating.
(7) Continuing
After the rotation is stopped and the related parts of the engine are checked in detail, if the rotation needs to be restored, the 'continue' button can be pressed down, the core machine automatically stops after finishing the rotation of one circle of residual travel, and if the core machine needs to be rotated one circle again, the 'rotate' or 'reverse rotation' button can be pressed down.
(8) Engine model selection
The function is essentially to select different gear ratios according to different engine models, which involve multiple calculations in the present procedure. The engine model selection component event monitoring function determines a gear ratio by selecting an engine model from which to calculate a commanded number of pulses.
(9) Series selection
The number of the engine stages is 9, and the 4 th stage is used as a reference in the hole detection, so the 4 th stage is placed at the beginning of the whole row edge options, the next other options are 1 stage, 2 stage, 3 stage, 5 stage, 6 stage, 7 stage, 8 stage and 9 stage in sequence, the index value of a pull-down list which sequentially corresponds to all the options from top to bottom is 0-8, the global variable can be assigned according to the corresponding relation, and the selected number of stages and the number of blades can be recorded by adopting different global variables. These two global variables can be referenced in the overall function, from which the number of leaves can be determined, followed by the number of leaves marked and returned marked, and specific algorithms are explained in detail in the marked leaves and returned marked sections.
(10) Rotor positioning
The rotor can be positioned after clicking the marking button, and the rotor positioning is actually determining the starting point position, namely a No. 1 blade, wherein the No. 1 blade is actually a specific blade of a certain determined stage (4 th stage of CFM56 high-pressure compressor and 9 th stage of LEAP high-pressure compressor) of the high-pressure compressor. When the servo motor driver works in a position mode, position pulse values are recorded in dn11 and dn12 registers in the driver, wherein the address of the dn11 register is 379, and fewer than ten thousands of position pulses are accessed; where dn12 register address is 380, tens of thousands of location pulses are accessed. When the driver is powered on, the position pulse value is unique corresponding to any position where the motor rotates, so that the rotor can be positioned according to the position pulse. After clicking the "rotor positioning" button, the internal program pauses rotation first, then sends an instruction to read the dn11 and dn12 registers, and when the serial port monitoring function monitors that there is data return, reads the returned data by using the statement inputstream. Read (readBuffer), but the data read into the array readBuffer needs to be subjected to format conversion, and the data format in the byte type array readBuffer is described below.
Wherein readBuffer is a byte type array defined as 9 elements. Each element in the byte type array is a byte type, the byte is a signed integer for accessing 8 bits, the value range is-128-127, but the data in each register is read by the upper 8 bits and the lower 8 bits, and the value ranges of the upper 8 bits and the lower 8 bits are-255, so that the problem of data format exists when the values of the registers are read by the byte type array readBuffer. When the value in the register is 0-127, reading the data to the array readBuffer, wherein the high eight bits are 0, and the low eight bits are still 0-127; when the data in the register is 128-255, reading the data to the array readBuffer, wherein the high eight bits are 0, the low eight bits are-128 to-1, when the data exceeds 256, the data is 1 to the high 8 bits, and the higher numbers are the same as each other; reading data to the array readBuffer when the value in the register is-1 to-127, wherein the upper eight bits are-1 and the lower eight bits are-1 to-127; when the value in the register is-128 to-256, reading data to the array readBuffer, wherein the upper eight bits are-1, and the lower eight bits are 128-0; the higher eight bits are decremented by 1 when the value in the register is less than-256, and the smaller numbers are then analogized.
Each time the data must be read and then processed in a data format before being converted into general-purpose data. After sending the command to read the dn11 and dn12 position pulses, the position pulse value for blade number 1 can be obtained and stored in the global variable fb.
(11) Marking
The damaged blade marking may be done during the engine's hole detection process when it is encountered, but the "rotor positioning" must be done before the "mark" button is clicked. After clicking the 'mark' button, the internal program reads the data in the registers dn11 and dn12, obtains the current position pulse z after data format conversion, but finally accesses the pulse number of the current blade from the blade No. 1 after the whole circle is removed when the high-voltage rotor of the engine rotates positively, and the current blade is realized by (z-fb)% (int) (500000/I) statement, and the data is stored in the corresponding array; the final data of the marks 1-9 are correspondingly stored in the array variables. Meanwhile, the number of stages of the marked blades is stored in a marking array; in addition, according to the accessed value (z-fb)% (int) (500000/I), the number of the current blade is obtained by multiplying the number of the blades of the stage where the current blade is located by the proportion of the number of the pulses which take up one cycle of the positive rotation of the engine rotor, and adding 1 to the number of the blades which take up the current blade. And finally, the number of the stage where the current blade is and the number of the blade are converted into a String type, and the String type is written into a text area of the current blade number for displaying to a user.
(12) Return mark
1. Firstly, acquiring an index value of a selected marking blade to be returned and storing the index value in a global variable re; 2. writing a Pn071 register to pause the motor; 3. sending out an instruction to read the values of dn11 and dn12 at the current position, obtaining a current position pulse z after data format conversion, and obtaining the pulse number of the current blade from the No. 1 blade after keeping the positive rotation of the engine rotor for the whole circle by the statement z= (z-fb)% (int) (500000/I); then, the difference p between the current position pulse value and the position pulse value of the marking blade to be returned is obtained by p=z-b [ re ]; 4. since there is play in the gear transmission from the motor to the high-voltage rotor of the engine if the direction of the rotor of the engine is changed during the return marking, the return inaccuracy is easily caused, so that the rotation direction of the high-voltage rotor of the engine is kept unchanged during the return marking in the embodiment. At this time, the value of P is two cases, P >0 and P <0. Referring to fig. 4 (a), when p >0, keeping the rotation direction of the engine unchanged, the number of pulses that need to go through is-p when returning to the marking blade that needs to be returned from the current position; referring to fig. 4 (b), when p <0, the number of pulses that need to be passed is also (int) (-500000/I) -p when returning to the marker blade that needs to be returned from the current position; judging the positive and negative of p by using if sentences in the program, calculating the number of pulses needing to be taken by adopting different methods, dividing ten thousands of pulses and less than ten thousands of pulses, respectively forming complementary codes of ten thousands of pulses and less than ten thousands of pulses, and respectively writing the complementary codes into Pn120 and Pn121 registers; 5. finally, the Pn071 register is written to cancel the pause triggering motor rotation.
(13) Clearing the mark
When another engine needs to be checked, the marked blade number needs to be cleared, and the implementation procedure designs a 'clear mark' button for executing the function, and when the 'clear mark' is pressed, the defect blade number stored in the pull-down list before is completely cleared, so that the marking can be restarted.
Whereas for functions in the smart terminal program the following explanation is made:
(1) Component behavior event listening function: each component in the program is provided with an added monitor when designing, and a component behavior event monitoring function is designed, but the source of the behavior event is needed to be judged before corresponding operation is executed after the behavior event is provided because the operation to be executed is different from the source of the behavior event. The variables are assigned in the functions executed by the behavior events, and the purpose of the assignment is to enable the program to execute only the part to be executed by the behavior event and not execute other parts after the program runs to the serial port event function.
(2) Data transmission function: the data transmission function is to transmit data outwards through the output stream outputstream, and because the communication protocol structure of Modbus is to transmit eight bytes of data together at a time, a global array defined in the program is used to store the data to be transmitted, and then the data is transmitted one by using the transmission function.
(3) Data receiving function: the Modbus communication method is used for receiving returned data, and the returned data is generated every time the data is sent out; therefore, after the program transmits the data in the transmitting function, the program automatically returns to the serial port event function, the returned data is stored in the byte array through calculation, and the returned data is byte, so that the returned data can be changed into 10-system data by performing format conversion. Many times, the program only needs to send a behavior event for a plurality of times, but after a group of data is sent, the program automatically jumps to the serial port event function.
