A photovoltaic laminate assembly misalignment monitoring system according to an embodiment of the present invention will first be briefly described with reference to the accompanying drawings. Fig. 1 shows a schematic block diagram of a photovoltaic laminate assembly misalignment monitoring system according to an embodiment of the present invention.

As shown in fig. 1, the photovoltaic lamination assembly misalignment monitoring system according to the embodiment of the invention includes a first lamination machine monitoring system 1001, a general controller 1002, and a display device 1003.

The first laminator monitoring system 1001 is connected to the main frame of the laminator and the laminating motor 1012, respectively, for monitoring the operation of the main frame and the laminating motor 1012,

the master controller 1002 calculates the running time difference between the host and the laminating motor 1012 when starting feeding based on the monitoring result of the first laminating machine monitoring system 1001;

the display device 1003 displays the change of the operating time difference with time.

Specifically, after the photovoltaic module enters the interior of the laminator, the first laminator monitoring system 1001 monitors the host machine and the laminating motor 1012 of the laminator respectively, the master controller 1002 calculates the running time difference between the host machine and the laminating motor 1012 of the laminator based on the monitoring result, and the display device 1003 displays the change of the running time difference along with time, such as a time change line graph, when the line graph is regularly evolved, the circuit structure design is reasonable, and if the potential difference is detected, the structure setting is indicated to have a problem, and the structure setting needs to be adjusted to be improved; when the line graph is in irregular evolution, namely the peak is suddenly high and suddenly low or the time difference from the peak to the trough is not constant, the circuit structure design is unreasonable, and an operator can improve the dislocation condition by adjusting the operation steps, the pulse and the like of the laminating machine. So, through this photovoltaic lamination subassembly dislocation monitored control system can effectual control out photovoltaic module at the inside dislocation reason of laminator, solve photovoltaic module and appear misplacing and take place pit and explode a phenomenon.

The photovoltaic laminated assembly dislocation monitoring system provided by the embodiment of the invention can be applied to a single-layer laminating machine and a multi-layer laminating machine.

For example, the laminator may be a double-layer laminator including a first host 1011 and a second host 1013, and the lamination motor 1012 may move up and down.

At this time, the first laminator detection system 1001 is respectively connected to the layer first host 1011 and the laminating motor 1012, and is configured to monitor operations of the first host 1011 and the laminating motor 1012.

Accordingly, the photovoltaic laminate assembly misalignment monitoring system also includes a second laminator monitoring system 1004.

The second laminator monitoring system 1004 is connected to the second mainframe 1013 of the double-layer laminator and the lamination motor 1012 located at the second layer, respectively, for monitoring the operation of the second mainframe 1013 and the lamination motor 1012 located at the second layer.

At this time, the general controller 1002 calculates a first operating time difference between the first host 1011 and the laminating motor 1012 at the time of starting feeding based on the monitoring result of the first laminator monitoring system 1001, and calculates a second operating time difference between the second host 1013 and the laminating motor 1012 at the time of starting feeding based on the monitoring result of the second laminator monitoring system 1004,

meanwhile, the display device 1003 displays the changes of the first operating time difference and the second operating time difference over time, respectively.

That is, the operating time difference line graph of the first layer and the operating time difference line graph of the second layer are displayed on the display device, respectively. Therefore, whether the circuit structures of the first layer and the second layer have problems or not can be visually judged, and the corresponding improvement can be carried out.

In the following, a misalignment monitoring method of a photovoltaic laminate assembly according to an embodiment of the present invention is described in detail with reference to fig. 2.

As shown in fig. 2, a method for monitoring misalignment of a photovoltaic laminate assembly according to an embodiment of the present invention includes the steps of:

s1: the operation of the laminator host machine and the operation of the lamination motor 1012 are monitored.

That is, the operation of the laminator and the lamination motor 1012 is monitored by the first laminator monitoring system 1001. Specifically, for example, the start time of the host computer, the start time of the lamination motor, and the like may be recorded by a synchronous timer or the like, respectively.

Preferably, the start signal can be captured and counted by an external Programmable Logic Controller (PLC). Further preferably, since laminator dislocations are typically in the centimeter level, the count conversion is performed based on the conversion of signal points and internal time calculations, and the monitoring time is accurate to the millisecond level.

S2: based on the operation monitoring result of the host and the operation monitoring result of the laminate motor 1012, the operation time difference between the host and the laminate motor 1012 is calculated.

Specifically, the running time difference between the host and the laminating motor 1012 is calculated based on the monitoring result of the first laminating machine monitoring system 1001, for example, by the overall controller 1002.

S3: the change in the running time difference over time is displayed.

Preferably, the display device 1003 may display a line graph of the operating time difference with time for more intuition.

S4: whether or not there is a misalignment and/or a cause of the misalignment is determined based on a change in the operating time difference with time.

In fact, a reasonably designed circuit has a regular variation of the running time difference with time, for example, the running time difference reaches a maximum value every fixed time interval, and then reaches a minimum value every fixed time interval, and so on. Moreover, the running time difference is zero to the maximum value, and the change is distributed in an equal difference mode. Specifically, if a line graph showing the variation of the operation time difference with time is shown, the horizontal axis represents time, and the vertical axis represents the operation time difference, it is shown that the peak width of each peak should be the same, and the slope from the valley to the peak should be the same. If the peak width, the peak height, the slope and the like are found to be changed, the unreasonable position of dislocation caused by the circuit structure design can be known, and the corresponding adjustment can be carried out according to the past empirical value. If the line graph is found to have no abnormality, and the dislocation is detected, the situation is that the structural matching is unreasonable and needs to be adjusted.

That is, the operator determines whether the photovoltaic module has a misalignment and/or a cause of the misalignment in the laminator according to the actual detection result of the laminate and the change of the operation time difference with time. After the photovoltaic module is dislocated, the dislocation situation can be improved by adjusting the operation steps, pulses and other methods of the laminating machine, so that the phenomena of dislocated pits and explosion of the photovoltaic module are solved.

Further, in step S1, a signal of the host and the lamination motor 1012 at the time of starting feeding is captured and the time when the signal is captured is recorded to monitor the operation of the host and the lamination motor 1012.

That is, the first laminator monitoring system 1001 begins monitoring the operation of the host and lamination motors 1012 by capturing a signal so that the first laminator monitoring system 1001 can quickly begin monitoring in response to the operating conditions of the photovoltaic laminate assembly inside the laminator.

Specifically, when the feeding is started, the start signals of the host and the laminating motor 1012 are captured by an external Programmable Logic Controller (PLC), so that the operation of the host and the laminating motor 1012 is monitored, and the first laminating machine monitoring system 1001 can quickly respond to the operation condition of the photovoltaic laminating assembly inside the laminating machine to start monitoring. Further preferably, since laminator dislocations are typically in the centimeter level, the count conversion is performed based on the conversion of signal points and internal time calculations, and the monitoring time is accurate to the millisecond level.

In step S2, the time when the signal of the host computer was captured and the time when the signal of the laminate motor 1012 was captured are calculated, and the time difference is calculated as the operation time difference.

Specifically, the master controller 1002 calculates the running time difference when starting the feeding based on the captured time when the signals of the host and the laminating motor 1012 are received, so that the error of the generation time in the monitoring process can be avoided, and the accuracy of the monitoring effect is improved.

Further, in step S2, the programmable logic control program performs count conversion on the signals to obtain the running time difference, and the precision of the running time difference is in the order of milliseconds.

The programmable logic control program has the characteristics of high reliability and high running speed, and the running time difference is accurate to millisecond level, so that the obtained running time difference has high accuracy and quick response, and the monitoring result is ensured to be optimal. The captured signals are counted and converted through an external Programmable Logic Controller (PLC), and the accuracy of response speed and running time difference is guaranteed.

Further, step S3 includes:

s31, generating a time line graph of the running time difference along the time based on the running time difference;

s32, a time line graph of the operating time difference over time is displayed.

In detail, the overall controller 1002 generates a time line graph based on the operation time difference, and the time line graph is displayed by the display device 1003, so that the operator can more intuitively know the change of the operation time difference along with the time by the time line graph.

Further, in step S4, it is determined whether or not there is a misalignment and/or a cause of misalignment based on the change with time of the peak in the operating time line graph.

A reasonably designed circuit whose running time difference changes with time is kept regular, for example, the running time difference reaches a maximum value every fixed time, then reaches a minimum value every fixed time, and the process is repeated. Moreover, the running time difference is zero to the maximum value, and the change is distributed in an equal difference mode. Specifically, the change in the operating time difference with time is represented by an operating time line graph, where the horizontal axis represents time and the vertical axis represents the operating time difference, and this is expressed in that the peak width of each peak should be the same and the slope from trough to peak should be the same. If the peak width, the peak height, the slope and the like are found to be changed, the unreasonable position of dislocation caused by the circuit structure design can be known, and the corresponding adjustment can be carried out according to the past empirical value. If the line graph is found to have no abnormality, and the dislocation is detected, the situation is that the structural matching is unreasonable and needs to be adjusted.

That is, the operator can clearly understand whether or not the photovoltaic laminate assembly is misaligned inside the laminator and/or the cause of misalignment, based on the actual detection result of the laminate, in combination with the change over time of the peak value in the time line graph displayed by the display device 1003. After the photovoltaic module is dislocated, the dislocation situation can be improved by adjusting the operation steps, pulses and other methods of the laminating machine, so that the phenomena of dislocated pits and explosion of the photovoltaic module are solved.

Further, when the peak value changes in magnitude over time beyond a predetermined threshold range, it is determined that there is misalignment of the photovoltaic laminate assembly, and the cause of the misalignment is from the circuit arrangement,

when the size change of the peak value is within a preset threshold value range along with the time and the actual dislocation of the photovoltaic laminated assembly is detected, judging that the cause of the dislocation is from the firmware setting,

and when the size change of the peak value is within a preset threshold value range along with the time and the dislocation of the photovoltaic laminating component is not detected, judging that the firmware setting and the circuit setting of the laminating machine are in a normal state.

That is, when the display device 1003 displays a time line graph of the operating time difference with the passage of time, the operator judges whether or not there is misalignment of the photovoltaic laminate assembly and the cause of the misalignment from the change with time of the peak value on the time line graph. Specifically, when the peak value of the line graph at a certain time point significantly increases or decreases and exceeds a predetermined threshold range, it can be determined that the photovoltaic laminate assembly is misaligned, and it is known from the time line graph that a problem occurs in the circuit arrangement; the time-dependent change value of the peak value on the line graph is always within the preset threshold range, and the fact that the photovoltaic laminating assembly really has the dislocation problem is actually detected, so that the dislocation reason can be judged to be the reason that the firmware of the laminating machine has the problem but not the circuit setting; the firmware setting and the circuit setting are both in a normal state only if the peak value on the line graph is always within the predetermined threshold value range over time and the photovoltaic laminate assembly is not misaligned during the inspection. Therefore, the operator can be helped to clearly judge whether the photovoltaic laminated assembly has dislocation or not and the reason of the dislocation.

The laminator includes a single layer laminator, a double layer laminator, and the like. The photovoltaic laminated component dislocation monitoring method provided by the embodiment of the invention can be suitable for dislocation monitoring of photovoltaic laminated components in a single-layer laminating machine and a double-layer laminating machine, and shows the adaptability of the photovoltaic laminated component dislocation monitoring method to different types of laminating machines.

The misalignment monitoring method of the photovoltaic laminate assembly according to the embodiment of the present invention is further described in detail below in conjunction with a double-layer laminator.

When the laminator is a double-layered laminator, the double-layered laminator includes a first main machine 1011 and a second main machine 1013, wherein a lamination motor 1012 can move up and down.

In step S1, the operation of the first main machine 1011 and the operation of the lamination motor 1012 on the first floor are monitored by the first laminator monitoring system 1001, and the operation of the second main machine 1013 and the operation of the lamination motor 1012 on the second floor are monitored by the second laminator monitoring system 1004, respectively.

That is, the photovoltaic laminate assembly misalignment monitoring system includes a first laminator monitoring system 1001 and a second laminator monitoring system 1004. From this, first layer all is equipped with lamination assembly dislocation monitoring system with the second floor in the double-deck laminator, can monitor the host computer on every layer and the operation of lamination motor 1012, compares in the photovoltaic lamination assembly dislocation control of individual layer laminator, has promoted the monitoring efficiency to photovoltaic lamination assembly by a wide margin.

In step S2, the operating time differences between the host and the laminating motor 1012 in the first layer and the second layer are calculated from the monitoring result obtained by the first laminator monitoring system 1001 and the detection result obtained by the second laminator monitoring system 1004, respectively.

Specifically, the overall controller 1002 calculates a first operating time difference between the first host 1011 and the lamination motor 1012 at the start of feeding based on the monitoring result of the first laminator monitoring system 1001, and calculates a second operating time difference between the second host 1013 and the lamination motor 1012 at the start of feeding based on the monitoring result of the second laminator monitoring system 1004.

In step S3, the time-dependent changes in the operating time difference between the first layer and the second layer are displayed.

After obtaining the operating time difference between the first layer and the second layer, the display device 1003 displays the change of the operating time difference between the first layer and the second layer with time.

In step S4, it is determined whether or not there is a misalignment and/or a cause of the misalignment based on the change in the operating time difference with time for each of the first layer and the second layer.

Through the line graphs of the running time difference of the first layer and the second layer changing along with time, when the line graphs of the first layer and the second layer are regularly evolved, the circuit structure of the double-layer laminating machine is reasonable in design, if the line graphs of the running time difference of a certain layer in the double-layer laminating machine changing along with time are detected to have a potential difference, the structure setting of the layer is indicated to have a problem, and the structure setting of the layer needs to be adjusted to be improved; when a certain layer of the line graph is irregularly evolved, namely the peak is suddenly high and suddenly low or the time difference from the peak to the trough is not constant, the circuit structure design of the layer is unreasonable, and an operator can improve the dislocation condition by adjusting the operation steps, the pulse and other methods of the laminating machine. So, through this photovoltaic lamination subassembly dislocation monitored control system can effectual control out photovoltaic module at the inside dislocation reason of laminator, solve photovoltaic module and appear misplacing and take place pit and explode a phenomenon.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
