Specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.
The application discloses a broken line detection method, a device, equipment and a readable storage medium of a yarn feeder, which solve the problem that an output signal cannot be directly used and a system cannot immediately respond to shutdown by carrying out secondary processing on the signal of the yarn feeder.
Referring to fig. 1, a first embodiment of the present application provides a yarn breakage detection method of a yarn feeder, which may be executed by a yarn breakage detection device (hereinafter referred to as a detection device) of the yarn feeder, and in particular, by one or more processors in the detection device, so as to implement the following steps:
s101, acquiring a first output signal of a yarn feeder in a current period;
in this embodiment, the detection device may be a PLC controller, a single chip microcomputer, or other types of controllers, and may be configured to receive a signal output by the yarn feeder in real time, analyze the signal, and then output a control signal to control the system.
It should be noted that, be configured with yarn package lead-out wire on the gravity pole of yarn feeder, at yarn feeding in-process, the circumstances that broken string or yarn sent can appear, the gravity pole on the yarn feeder will fall this moment, and at this moment, the system should shut down immediately, avoids the yarn to carry too much, and then leads to cloth cover quality to reduce even form the problem such as waste cloth. However, in the prior art, most yarn feeders are powered by alternating current, a constant high-level signal is output before the yarn is not broken and the gravity rod falls, and when the yarn is broken and the gravity rod falls, a pulse square wave alternating signal with high level and jump is output, and compared with a normal level signal, the output signal of the yarn feeder cannot be directly used, so that the system cannot respond to shutdown rapidly.
In this embodiment, the output signal of the yarn feeder can be collected in real time, and it can be understood that, before the gravity rod falls, the output signal is a high level signal, and after the gravity rod falls, the output signal is a pulse square wave alternating signal of high level and jump. Which may periodically segment the acquired signal.
S102, judging whether the first output signal is in a rising edge state or a falling edge state;
in this embodiment, the edge state is determined by comparing the end state of the previous period with the start state of the first output signal, specifically: and if the end of the previous circle is at a high level, the start of the first output signal is at a low level, the edge state of the first output signal is in a falling edge state, and similarly, if the end of the previous circle is at a low level, the start of the first output signal is at a high level, the edge state of the first output signal is in a rising edge state.
S103, when the first output signal is judged to be in a rising edge state, storing the first output signal into a current latch array, and when the number of signals stored in the latch array reaches a first preset value, resetting the latch array and outputting a second output signal representing high level;
specifically: in this embodiment, when the first output signal is determined to be in a rising edge state, a flag bit of a rising edge is set, and the first output signal is stored in a current latch array, and a counter is controlled to start counting;
when the number of the first output signals stored in the current latch array reaches a first preset value according to the count value of the counter, resetting the rising edge flag bit, resetting the counter, performing AND operation on the first output signals in the current latch array, and generating an operation result;
and when the operation result is judged to be 1, the latch array is cleared, and a second output signal representing a high level is output.
It should be noted that the first preset value may be 15 (but is not limited thereto), and it should be understood that the first output signals stored in 15 are stored for performing the and operation, if the result of the operation is 1, it is indicated that the data stored in all periods are high level, and the current stable high level signal is proved, and the second output signal representing the high level is outputted.
S104, after judging that the first output signal is in a falling edge state, storing the first output signal into a current latch array, and resetting the latch array to obtain a second output signal representing low level;
when the first output signal is judged to be in a falling edge state, 15 periods after the rising trigger is latched are mainly used for judging whether the high level and the low level are stable and have no jump, and after 15 periods are full, the falling edge flag bit is cleared, and a low level, namely a 0 signal is output through one-time filtering. It should be understood that the period is counted from the edge, so it is necessary to wait until the rising edge is triggered to start counting, and of course, in other embodiments, the storing may be directly started, which is not limited herein.
S105, judging whether the second output signal is in a rising edge state or a falling edge state
It should be noted that, the edge state of the second output signal is judged to be similar to the edge state of the first output signal, and details are not repeated here.
S106, when the second output signal is judged to be in a rising edge state, the second output signal is stored in a current accumulator to be accumulated, when the accumulation times of the accumulator reach a second preset value, the accumulator is cleared, and a third output signal is output according to the accumulation value of the accumulator; the second preset value is larger than the first preset value
Specifically, in this embodiment, when the second output signal is determined to be in a rising edge state, a rising edge flag bit is set, and the second output signal is stored in a current accumulator to be accumulated, and the counter is controlled to start to count;
when the accumulated times reach a second preset value according to the count value of the counter, resetting the rising edge flag bit and resetting the counter;
and resetting the accumulator, and outputting a third output signal according to the accumulated value of the accumulator.
More specifically: outputting a third output signal representing a high level when it is determined that the accumulated value of the accumulator is greater than a preset threshold;
and outputting a third output signal representing a low level when the accumulated value of the accumulator is judged to be smaller than a preset threshold value.
It should be noted that the second preset value may be 600 (but not limited to this), it should be understood that the second output signals of 600 consecutive periods are summed together, and after 600 periods pass, the rising edge flag bit is cleared, and the calculator is cleared, and if the summed value is in the range of 598-600 (but not limited to this, the range may be 596-600), the state of the input is determined to be continuously high (there may be a disturbance in the allowing process resulting in a respective low level), and then the high level signal, i.e. the 1 signal, is output by the secondary filtering.
It should be noted that in this embodiment, it can be understood that the first preset value and the second preset value may also be set by writing through external communication, and are not program-written and cured, so that more flexible parameter configuration is realized.
S107, after judging that the second output signal is in a falling edge state, resetting the accumulator, and outputting a third output signal representing low level;
it should be noted that, the secondary filtering signal takes the output of the primary filtering signal as the input (i.e. the second output signal is taken as the secondary filtering input signal), and the latching modes adopted are different, because the period of the secondary filtering signal is longer, and the latching mode adopting array latching occupies a large amount of memory space, so that the latching mode adopting accumulation and summation is that the accumulation of the input signal level condition is carried out at the beginning of rising edge triggering, the accumulation is carried out until the count value is full, whether the accumulated value is equal to or greater than the count value is judged, if yes, the conditions of high level are all described, if not, the high-low level change exists in the middle is described; when the signal is descending, the flag bit and the count value of the rising edge are cleared, and meanwhile delay judgment is also carried out, so that disturbance is prevented.
S108, judging the current disconnection condition according to the third output signal.
It should be noted that when the third output signal indicates a low level, it is determined that the gravity rod of the yarn feeder falls, the system can rapidly respond to stop, and excessive yarn feeding is avoided.
The beneficial effects of the above embodiment at least include:
(1) The original yarn feeder can not directly use signals and is converted into single usable signals;
(2) The trigger response time of the falling edge is controlled within 2-3 periods of actual interrupt execution, and if the interrupt period is shortened, the response time is shorter, so that the yarn conveying is greatly protected.
