Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the embodiments described are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a block diagram of an embodiment of a data acquisition system 100 according to the present disclosure. The data acquisition system 100 is used to perform data acquisition on the device 10. The data acquisition system 100 includes: vibration sensor 20, data collection station 30 and laser trigger device 40. In the embodiment of the present application, the vibration sensor 20 and the laser trigger device 40 are both disposed on the apparatus 10. The data collector 30 is electrically connected to the vibration sensor 20 and the laser trigger device 40.
In the present embodiment, the apparatus 10 generates vibration signals in real time during the machining process. The apparatus 10 includes a first state and a second state. The first state and the second state are different according to the type and structure of the device 10, and the specific distinction will be illustrated in detail below.
The vibration sensor 20 is used for converting a vibration signal generated by the device 10 in real time during the machining process into an electric signal. It is understood that the electrical signal may be a voltage value.
The laser trigger device 40 is used for outputting a laser signal. The laser triggering device 40 is further configured to output a first signal when the apparatus 10 is in a first state and a second signal when the apparatus 10 is in a second state.
In one embodiment, the first signal is a trigger signal, which is opposite in level to the second signal. For example, the first signal is a high level signal and the second signal is a low level signal. It is understood that the first signal may also be a low level signal, and the second signal may be a high level signal.
The data collector 30 is configured to trigger the data collector 30 to collect the electrical signal sent by the vibration sensor 20 when receiving the first signal sent by the laser triggering device 40.
In this embodiment, the data collector 30 is a high-speed data collector, and the collection frequency thereof is generally 2 5 K～2 8 K times per second. For example, in one embodiment, the acquisition frequency may be 2 6 K times/second, i.e. 64000 times/second.
In this embodiment, by setting a specific signal trigger (for example, a trigger when only the first signal is received) on the data collector 30, it can be ensured that the data collector 30 only collects signals generated at the moment when the device executes a specific action, and accurate segmentation of signal data is achieved.
Referring to fig. 2, in the present embodiment, the apparatus 10 includes a first member 11 and a second member 12. The first part 11 can be fixedly arranged. The second part 12 is periodically movable relative to the first part 11.
In one embodiment, the laser triggering device 40 includes a light barrier 41 and a laser sensor 42. The light barrier 41 is arranged in correspondence with the first part 11, for example on the first part 11. The laser sensor 42 is arranged in correspondence with the second component 12, for example on the second component 12. Wherein the laser sensor 42 is used for outputting the laser signal. When the second component 12 moves periodically relative to the first component 11, the second component 12 drives the laser sensor 42 to move relative to the light barrier 41 disposed on the first component 11, so that the laser signal emitted by the laser sensor 42 is blocked by the light barrier 41. Wherein, when the second component 12 moves periodically relative to the first component 11, so that the laser signal output by the laser sensor 42 is blocked by the light barrier 41, the device 10 is in the first state. At this time, the laser sensor 42 also outputs the first signal. The device 10 is in the second state when the second part 12 is moved periodically relative to the first part 11 such that the laser signal output by the laser sensor 42 is not blocked by the light barrier 41. At this time, the laser sensor 42 also outputs the second signal.
It will be appreciated that the light barrier 41 and the laser sensor 42 may be interchanged. That is, the laser sensor 42 is disposed on the first member 11, and the light blocking plate 41 is disposed on the second member 12. It is only necessary to ensure that the light barrier 41 and the laser sensor 42 can move relatively, so that the laser signal output by the laser sensor 42 is shielded or not shielded by the light barrier 41. This is also true in the following embodiments, which are not described in detail.
It is understood that the laser triggering device 40 in the data acquisition system 100 described above can be applied to different apparatuses, and the working principle of the laser triggering device 40 will be described in detail below with reference to fig. 3 to 7.
Referring to FIG. 3, in one embodiment of the present application, the apparatus 10 may be a forging apparatus, a stamping apparatus, a forming machine, or the like, used in industrial processes. For example, the first member 11 is specifically a lower mold 111, and the second member 12 is specifically an upper mold 121 disposed opposite to the lower mold 111. The upper mold 121 may linearly reciprocate up and down with respect to the lower mold 111. The light barrier 41 is disposed on the upper mold 121 of the apparatus 10, and the laser sensor 42 is disposed on the lower mold 111 for emitting the laser signal.
When the apparatus 10 starts to close the mold, the light barrier 41 moves with the upper mold 121 toward the lower mold 111. When the apparatus 10 enters the mold clamping moment, the light barrier 41 moves to a position (shown in the figure) capable of blocking the laser signal emitted by the laser sensor 42, the apparatus 10 enters the first state, and the laser trigger device 40 starts to output the first signal through the laser sensor 42. When the light barrier 41 moves to a position where the laser signal of the laser sensor 42 cannot be irradiated (i.e., the laser signal is not blocked), the mold clamping moment ends, the apparatus 10 enters the second state, i.e., enters the other time of the non-mold clamping moment, the laser trigger device 40 no longer outputs the first signal, and the laser sensor 42 outputs the second signal.
Obviously, the laser triggering device 40 is disposed on the upper die 121 and the lower die 111 of the apparatus 10 to cooperate with the data collector 30, so that signals generated only at a moment when the apparatus 10 performs a certain specific action (for example, at a moment when the apparatus is clamped) are collected, accurate segmentation of signal data is realized, the subsequent calculation amount for processing data is reduced, and the efficiency for monitoring the abnormality of the apparatus 10 is improved.
Of course, in other embodiments, when the device 10 is in the second state, the laser trigger device 40 may not output the second signal, i.e. only output the laser signal and not output other signals.
Referring to fig. 4, in another embodiment of the present application, the apparatus 10 may be an apparatus with a ball screw, a molding machine, a pin inserting machine, etc. used in industrial production. For example, the first component 11 is embodied as a stationary base 112 and the second component 12 is embodied as a linear motion motor member 122. The linear motion motor member 122 may perform a horizontal linear reciprocating motion with respect to the stationary base 112.
The light barrier 41 is disposed on the fixed base 112 of the apparatus 10, and the laser sensor 42 is disposed on the linear motion motor member 122 for emitting a laser signal. The laser sensor 42 always emits a laser signal at a certain range when the device 10 is normally operated.
When the linear motion motor member 122 is in the forward stroke, it gradually approaches the fixed base 112, and the laser signal emitted by the laser sensor 42 also gradually approaches the light barrier 41. Until the laser signal can be irradiated onto the light barrier 41, that is, the laser signal is blocked by the light barrier 41, the device 10 enters the first state, and the laser triggering device 40 outputs the first signal through the laser sensor 42.
When the linear motion motor member 122 is in the return stroke, it gradually moves away from the fixed base 112, and the laser signal emitted by the laser sensor 42 also gradually moves away from the light-blocking plate 41. Until the laser signal can not irradiate the light barrier 41 any more, that is, the laser signal is not blocked by the light barrier 41, the device 10 enters the second state, the laser triggering device 40 no longer outputs the first signal, and the laser sensor 42 outputs the second signal.
It can be understood that the range of the laser signal emitted by the laser sensor 42 can be adjusted, for example, the maximum range of the laser signal is 300mm, and in the actual data acquisition process, the range of the laser signal can be adjusted according to the length of the time period required to be acquired.
Referring to fig. 5, in another embodiment of the present application, the equipment 10 may be a CNC machine, a fan, other equipment with a rotating shaft, and the like. For example, the first part 11 is embodied as a stationary base 112 and the second part 12 is embodied as a circular motion machine member 123. The circular motion mechanism 123 performs circular motion with a fixed point as a center.
The light barrier 41 is disposed on the fixed base 112 of the apparatus 10, the laser sensor 42 is disposed on the circular motion motor member 123, and a laser signal is emitted outwards along a radius direction of a circle formed by a motion track. The laser sensor 42 will periodically approach and move away from the fixed base 112 during the circular motion of the circular motion motor member 123. For example, when the circular motion motor member 123 gradually approaches the fixed base 112 and moves to a certain angle, the laser signal emitted from the laser sensor 42 will start to irradiate on the light-blocking plate 41. At this time, the laser signal is blocked by the light barrier 41, the device 10 enters the first state, and the laser trigger device 40 outputs the first signal through the laser sensor 42.
As another example, when the circular motion mechanism 123 gradually moves away from the fixed base 112 and when it moves to another angle, the laser signal emitted by the laser sensor 42 no longer irradiates on the light barrier 41. At this time, the laser signal is not blocked by the light barrier 41, the device 10 enters the second state, the laser trigger device 40 no longer outputs the first signal, and the laser sensor 42 outputs the second signal.
Referring to fig. 6, it will be appreciated that in another embodiment of the present application, the apparatus 10 may be an automated line belt conveyor, a logistics bin conveyor, or the like. At this time, the circular motion mechanism 123 may make a periodic motion of another trajectory around a point as a center. For example, the circular motion machine member 123 is fixedly disposed on the belt conveyer 13 of an automatic production line, the laser sensor 42 is disposed on the circular motion machine member 123, and the laser sensor 42 periodically approaches and departs from the fixed base 112 with the normal operation of the belt conveyer 13. Obviously, when the device 10 is an automatic production line belt transmission device, a logistics warehouse conveyor belt, etc. shown in fig. 6, it outputs corresponding laser signals, and the principle of the first signal and the second signal is similar to that of the device 10 shown in fig. 5, and will not be described again here.
Referring to fig. 7, in another embodiment of the present application, the apparatus 10 may be a large pendulum apparatus, or an entertainment facility for pendulum sports, or the like. For example, the first part 11 is embodied as a stationary base 112 and the second part 12 is embodied as a pendulum motor member 124. The pendulum motor member 124 performs a periodic pendulum motion within a certain range around a fixed point.
The light barrier 41 is disposed on the fixed base 112 of the apparatus 10, and the laser sensor 42 faces the direction of the fixed base 112 and is disposed on the pendulum motor member 124 for emitting a laser signal. The laser sensor 42 is periodically moved toward and away from the stationary base 112 during the pendulum movement of the pendulum motor member 124. For example, when the pendulum motor member 124 gradually approaches the fixed base 112 and moves to a certain angle, the laser signal emitted from the laser sensor 42 is irradiated on the light-blocking plate 41. At this time, the laser signal is blocked by the light barrier 41, the device 10 enters the first state, and the laser triggering device 40 outputs the first signal.
As another example, when the pendulum mechanism 124 gradually moves away from the fixed base 112 and moves to another angle, the laser signal emitted from the laser sensor 42 no longer irradiates on the light barrier 41. At this time, the laser signal is not blocked by the light barrier 41, the device 10 enters the second state, the laser trigger device 40 no longer outputs the first signal, and the laser sensor 42 outputs the second signal.
It will be appreciated that the laser triggering device 40 comprises a light barrier 41 and a laser sensor 42, as described above. Of course, in the embodiment of the present application, the laser trigger device 40 may also include other components, i.e., the structure of the laser trigger device 40 is not limited. For example, referring to fig. 8, in another embodiment of the present application, the laser triggering device 40a includes a transmitter 43 and a receiver 44. The transmitter 43 is disposed on the second component 12 and is used for receiving and transmitting the laser signal. The receiver 44 is disposed on the first member 11 for receiving a laser signal.
For convenience of description, the positional relationship and the operation principle between the laser trigger device 40a and the apparatus 10 will be described by taking the apparatus 10 as a forging apparatus, a stamping apparatus, a molding machine, and the like for industrial production. Of course, the laser triggering device 40a can also be applied to the apparatus 10 shown in fig. 4 to 7, which is not described herein again.
Specifically, referring to fig. 9, in one embodiment, the transmitter 43 is disposed on the upper mold 121 and the receiver 44 is disposed on the lower mold 111.
When the tool 10 starts to be clamped, the transmitter 43 moves with the upper mold 121 in the direction of the lower mold 111. When the machine 10 enters the mold clamping moment and the transmitter 43 moves to a position where the receiver 44 can receive the laser signal, the machine 10 enters the first state, and the laser trigger device 40 further outputs the first signal through the transmitter 43. When the transmitter 43 again moves to a position where the receiver 44 does not receive the laser signal, the clamping moment ends and the apparatus 10 enters the second state, i.e., the rest of the non-clamping moment. At this time, the laser trigger device 40 outputs the first signal no longer, but outputs the second signal through the transmitter 43.
Similarly, the positions of the transmitter 43 and the receiver 44 may be reversed, i.e. the receiver 44 is arranged on the second part 12 for receiving the laser signal and the transmitter 43 is arranged on the first part 11 for transmitting the laser signal.
Referring again to fig. 1, in an embodiment of the present application, the device data acquisition system 100 further includes a control unit 50. The control unit 50 is electrically connected to the data collector 30, and is configured to perform data processing on the electrical signals collected by the data collector 30. The control unit 50 may be, for example, an industrial personal computer.
Specifically, the data processing of the electrical signal acquired by the data acquisition device 30 by the control unit 50 includes: extracting effective signals and removing high frequency of the effective signals. The effective signal is a signal generated at the moment when the apparatus 10 performs a specific operation, for example, a signal generated at the moment when the apparatus 10 having the lower mold 111 and the upper mold 121 is clamped.
Referring to fig. 10, in the embodiment of the present application, taking three vibration sensors 20 shown in fig. 10 (a), 10 (b) and 10 (c) as an example (one vibration sensor 20 is installed at each of three different positions of the apparatus 10), a process of the control unit 50 extracting the effective signal will be described.
Taking the apparatus 10 with upper and lower molds as an example, to complete one mold opening and closing process, the laser trigger device 40 will complete one trigger. For example, in the second vibration sensor 20 shown in fig. 10 (b), an effective signal at the moment of mold clamping appears as shown in fig. 10 (d). Then, as shown in fig. 10 (e), the signal is windowed, that is, a part of the effective signal is processed, so as to perform high frequency removal processing by segmentation.
In this embodiment of the present application, the performing high frequency elimination processing on the effective signal includes: acquiring a cut-off frequency; converting the effective signal into a frequency domain signal from a time domain signal through Fourier transform; and reserving the signals below the cut-off frequency in the frequency domain signals, and converting the signals into time domain signals to obtain the signals subjected to high-frequency removal processing.
Fig. 11 is a schematic diagram illustrating the high frequency elimination of the effective signal according to this embodiment. As shown in fig. 11 (a), the effective signal has many glitches (i.e., high-frequency components). For better display of the result, the effective signal is converted from a time domain signal to a frequency domain signal by fourier transform, as shown in fig. 11 (b). Next, a high-frequency interference signal having a cutoff frequency (for example, 1 kHz) or higher is removed by a filter, and then, inverse fourier transform is performed to convert the signal into a time domain signal, thereby generating a high-frequency removed signal as shown in fig. 11 (c).
By extracting the effective signal and removing the high frequency from the electrical signal taken by the vibration sensor 20, more accurate signal data can be obtained so as to monitor the state of the device 10 well.
According to the embodiment of the application, the laser trigger device 40 is arranged on the first part 11 and the second part 12 of the equipment 10, so that signals generated in the moment when the equipment 10 performs a certain specific action are only acquired, accurate segmentation of signal data is realized, the subsequent calculated amount for processing the data is reduced, and the efficiency for monitoring the abnormality of the equipment 10 is improved.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present application and are not used as limitations of the present application, and that suitable modifications and changes of the above embodiments are within the scope of the claims of the present application as long as they are within the spirit and scope of the present application.
