Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. Based on the embodiments of the present application, every other embodiment that a person skilled in the art would obtain without making any inventive effort is within the scope of protection of the present application.
First, application scenarios applicable to the present application will be described. The control system of the cigarette making machine can be applied to a control system of the cigarette making machine.
According to research, the cigarette control system needs to detect the output frequency of the cigarette paper motor to control the operation frequency of subsequent processing equipment to be matched with the output frequency of cigarette paper, so that the production frequency of a plurality of cigarette processing procedures is matched, and qualified cigarette products are produced.
In the prior art, two methods for calculating the output pulse frequency of the cigarette paper are generally adopted, the first method for calculating the output pulse frequency of the cigarette paper is a method for counting by adopting a time gate, namely counting cigarette paper output measurement pulses in a time threshold, when the period of the cigarette paper output measurement pulses is far smaller than the time gate, the pulse measurement mode of the method is more accurate, but when the period of the cigarette paper output pulses is close to the time gate or is larger than the time of the time gate, a method for detecting the cigarette paper output pulses by adopting the time gate has larger measurement error; the second calculation method of the output pulse frequency of the cigarette paper is to scan the period of the output pulse of the cigarette paper through the system, and when the system scanning frequency is far smaller than the output pulse frequency of the cigarette paper, the pulse period scanned by the system has larger measurement error. In the starting process of the cigarette machine, the output frequency of the cigarette paper is gradually changed from low to high, so that inaccurate measurement of the output frequency of the cigarette paper can be generated in the production process no matter which measurement mode is used. The measurement of the pulse frequency can directly influence the matching frequency of a plurality of subsequent production process flows, and the quality of cigarettes is easily influenced under the condition of inaccurate measurement of the output frequency of the cigarette paper. Meanwhile, the output of the motor of the cigarette paper can truly output the cigarette paper to the next processing flow only through the adjustment of a plurality of gears, and certain errors exist between the output frequency of the motor of the cigarette paper and the real output frequency of the cigarette paper, so that the accurate measurement of the output frequency of the motor of the cigarette paper is difficult to achieve the complete matching with the frequencies of other processing equipment.
Based on this, the embodiment of the application provides a frequency control method, a device and a medium of a cigarette machine, so that the working frequencies of a plurality of processing devices in the cigarette machine are completely matched with the actual output frequency of cigarette paper, the working frequencies of a feeding device, a gluing device, a sealer, a cutting device and a spraying device after the output of the cigarette paper are matched with the output frequency of the cigarette paper, and the problems of uneven feeding, uneven gluing, inconsistent drying temperature and the like caused by the fact that the working frequencies are not matched are avoided, and the effect of improving the quality of cigarettes is achieved.
Referring to fig. 1, fig. 1 is a flowchart of a frequency control method of a cigarette making machine according to an embodiment of the present application. As shown in fig. 1, the frequency control method of the cigarette making machine provided in the embodiment of the application includes:
s101, determining whether an interrupt trigger event is generated or not by detecting the running state of a cigarette paper output cam;
in the step, the cigarette paper of the cigarette making machine is output outwards by taking a cigarette paper output motor as power, the cigarette paper output by the motor is required to be subjected to direction conversion control of a plurality of gears, and finally the cigarette paper is output to the next production link through a cigarette paper output cam.
Specifically, when the motor in the paper feeding device is started, a driving force for driving the paper output cam to rotate is generated; when the cigarette paper output cam rotates under the action of the driving force, if the rising edge of a pulse signal for indicating the rotation action of the cigarette paper output cam is detected, determining that an interrupt trigger event is generated; if the rising edge of the pulse signal is not detected, determining that an interrupt trigger event is not generated.
For example, a proximity switch may be installed at a detection position of the paper output cam, and when the paper output cam runs one turn, the proximity switch is approached once, thereby generating a pulse signal once. The cigarette machine control system detects a pulse signal of the rotation action of the cigarette paper output cam, determines that an interrupt trigger event is generated when the rising edge of the pulse signal is detected, and determines that the interrupt trigger event is not generated when the rising edge of the pulse signal is not detected.
In this way, the cigarette machine control system can detect the cigarette paper output and trigger an interrupt trigger event via rotation of the cam.
If step S101 determines that an interrupt trigger event is generated, the input hardware interrupt routine is started. The hardware interrupt routine executes the processing of steps S102 to S105.
S102, acquiring a time value at the moment of starting an input hardware interrupt program, storing the time value into a pulse time storage block, and moving each element stored in the pulse time storage block by one bit according to a first-in first-out principle.
In the step, the cigarette machine control system recognizes the local time value of the cigarette machine control system every time the input hardware interrupt program is started once, stores the local time value into a preset pulse time storage block, stores the time value according to the first-in first-out principle when storing the time value, moves one bit backwards when storing a new time value, and the last bit is extruded out of the storage block and is deleted.
For example, according to the production frequency of the cigarette making machine and the accuracy of the frequency calculation, the storage blocks can be set to ten storage bits, and the numbers from the first bit to the last bit are t (0) to t (9), when the input hardware interrupt program is started once, the cigarette making machine control system detects the local time and clears the time value stored in the original t (9), the time values stored in the original t (0) to t (8) are moved to the t (1) to t (9) storage blocks, and meanwhile the local time identified by the property is stored to the t (0) to obtain a new pulse time storage block.
Thus, the cigarette making machine control system can update the pulse time storage block in real time according to the starting of the input hardware interrupt program.
S103, judging whether the pulse time storage block is full.
Specifically, the step of judging whether the pulse time storage block is full by the cigarette making machine control system comprises the following steps: detecting whether the data of the last storage bit of the pulse time storage block is zero; if the data of the last storage bit is not zero, determining that the pulse time storage block is full; and if the data of the last storage bit is zero, determining that the pulse time storage block is not full.
It should be noted that, according to the description of the storage rule of each storage bit in the pulse time storage block in step S102, when the pulse time data is stored to the last storage bit, it is verified that the pulse time storage block is full.
And S104, if the pulse time storage block is full, calculating the pulse period of the cigarette paper output cam based on the stored time value in the pulse time storage block.
In this step, the step of calculating the pulse period of the paper output cam based on the time value stored in the pulse time storage block includes: calculating a time difference between a time value of the pulse time storage block located in the first storage bit and a time value of the pulse time storage block located in the last storage bit; dividing the time difference value by the number of storage bits included in the pulse time storage block to obtain a pulse average value; and determining the pulse average value as the pulse period of the cigarette paper output cam.
For example, when the cigarette machine control system determines that the pulse time storage block is full, the cigarette machine control system reads the time value of t (n) in the last storage bit and the time value of t (0) in the first storage bit, calculates the difference between the time value of t (0) in the first storage bit and the time value of t (n) in the last storage bit, and divides the time difference by the number (n+1) of storage bits included in the pulse time storage block to obtain the pulse period of the cigarette paper output cam at this time.
Specifically, the pulse period of the paper output cam is calculated by the following formula:
T＝(t(0)-t(ｎ))/(ｎ+1) (1)
In formula (1), t (0) represents a time value in the first memory bit, t (n) represents a time value in the last memory bit, and (n+1) represents the number of memory bits included in the pulse time memory block.
Thus, the pulse period closest to the actual output period value of the cigarette paper at the moment can be obtained through calculation of the pulse time average value.
Optionally, if the control system of the cigarette making machine determines that the pulse time storage module is not full, the pulse period is not calculated, and in order to ensure the smoothness of the pulse period, the pulse period is not calculated until the pulse period is full.
S105, calculating and outputting the actual output frequency value of the cigarette paper before feeding the other processing equipment according to the pulse period.
In this step, the step of calculating the actual output frequency value of the cigarette paper from the pulse period is performed in the controller.
Specifically, the step of calculating the actual output frequency value of the cigarette paper according to the pulse period comprises the following steps: determining a first operational intermediate value and a second operational intermediate value based on a clock precision of the controller; determining a first period reference value based on the pulse period and a second operational intermediate value; and obtaining the actual output frequency value of the cigarette paper based on the first operation intermediate value and the first period reference value.
The second operational intermediate value may be 2.0X10 4 The first period reference value may be calculated by the following formula:
W＝T/(2.0×10 4 ) (2)
in the formula (2), W represents a first period reference value, 2.0X10 4 Is the second operational intermediate value. Thus, the controller can calculate the first period reference value according to equation (2).
Specifically, the first operation is intermediateThe value may be 5.0X10 4 The actual output frequency value of the cigarette paper is calculated by the following formula:
F＝(5×10 4 )/W (3)
in the formula (3), W represents a first period reference value, F represents an actual output frequency value of the cigarette paper, 5.0X10 4 Is the first operational intermediate value.
Thus, the actual output frequency value of the cigarette paper can be obtained through the operation of the formula (2) and the formula (3).
Optionally, the controller determines the working state of the motor in the cigarette paper conveying device through a cigarette machine control system, and if the working state of the motor is in an operating state, calculates the actual output frequency value of the cigarette paper before feeding the other processing equipment according to the pulse period; and if the working state of the motor is in a stop state, determining the actual output frequency value of the cigarette paper based on the first operation intermediate value and the second period reference value.
When the motor is in a stop state, the controller outputs the actual output frequency of the cigarette paper in the stop state through a second period reference value and a first intermediate operation value, wherein the second period reference value is a constant larger than the first intermediate operation value.
Specifically, the step of determining the actual output frequency value of the cigarette paper based on the first operational intermediate value and the second periodic reference value includes: calculating the ratio of the first operation intermediate value to the second period reference value; and (5) rounding the ratio upwards to obtain the actual output frequency value of the cigarette paper.
For example, when the motor is in a stop state, the controller will force the second period reference value to 60000, and at this time, the controller calculates the actual output frequency value of the cigarette paper by the following formula:
F＝(5×10 4 )/60000 (4)
in the formula (4), F represents the actual output frequency value of the cigarette paper, 5.0X10 4 For the first operational intermediate value 60000 is forced for the second period reference value.
And (3) calculating according to the formula (4), and carrying out upward rounding to obtain the actual output frequency value of the cigarette paper at the time of stopping.
Therefore, the clock precision in the controller is unified to be 1 nanosecond through the operation of the first operation intermediate value, the second operation intermediate value and the first period reference value, and meanwhile, when the cigarette making machine is stopped, the actual output frequency value of cigarette paper of the cigarette making machine is zero when the cigarette making machine is stopped through the assignment of the second period reference value, so that the follow-up cigarette frequency measurement work cannot be influenced due to the reasons of stopping test and the like.
From a comparison table (table 1) of the actual output frequency value of the improved cigarette paper and the actual measurement value measured by the oscilloscope at various cigarette machine speeds, it can be seen that the calculated output frequency value of the cigarette paper and the measurement value of the oscilloscope have extremely small errors.
Table 1: and the cigarette paper output frequency value is compared with the measured value of the oscilloscope and the error rate.
| Device speed (branch/minute) | Oscilloscope measuring frequency (Hz) | Cigarette paper output frequency (Hz) | Error rate (%) |
| 100 | 4.053 | 4.052 | 0.025 |
| 500 | 20.375 | 20.365 | 0.049 |
| 1000 | 40.535 | 40.506 | 0.072 |
| 2000 | 81.067 | 80.988 | 0.097 |
| 3000 | 121.625 | 121.492 | 0.109 |
| 4000 | 162.146 | 161.945 | 0.124 |
| 5000 | 202.785 | 202.442 | 0.169 |
| 6000 | 243.231 | 242.702 | 0.217 |
| 7000 | 283.034 | 282.312 | 0.255 |
S106, controlling the working frequency of the other processing equipment in the cigarette making machine according to the output actual output frequency value of the cigarette paper.
In the step, the cigarette machine control system controls the working frequency of other processing equipment according to the actual output frequency of the output cigarette paper.
According to the frequency control method, device and medium for the cigarette making machine, the problem that the working frequency of other processing equipment cannot be matched with the output frequency of the cigarette making machine to influence the quality of cigarettes is solved by detecting the cigarette paper output cam and measuring the output frequency of the cigarette paper through the interrupt program, and the effects that the working frequency of a plurality of processing equipment in the cigarette making machine is completely matched and the quality of cigarettes is improved are achieved.
