Description

Technical Field

[0001] The present invention relates to the technical field of paper quality control, and in particular to a method and system for synchronizing the operation and data of multiple paper detection scanning frame mobile carriages. Background Art

[0002] Paper plays a vital role in daily life and production. During the paper production process, indicators such as basis weight, moisture content, and coating weight are crucial features for controlling its quality. To ensure that paper products meet specified quality and performance requirements, paper machines generally require a paper quality control system (QCS). Intelligent paper scanning frames are a key component of QCS systems. The scanning frame's carriage, used for paper quality testing, is typically equipped with sensors for basis weight, moisture content, and thickness. During the testing process, paper produced by the paper machine passes longitudinally through the center of the sensor mounted on the carriage, which then continuously reciprocates in the horizontal direction. Generally, in QCS systems that do not require detection of coating weight or moisture content changes, there is only one scanning frame. However, in systems that do require detection of coating weight or moisture content changes, two or more scanning frames are required.

[0003] The current QCS system composed of multiple scanning frames generally does not have the movement and data synchronization of the scanning frame carriage. Therefore, when calculating the coating amount, the scanning paths of several scanning frames relative to the paper are often not the same. That is, the path scanned by the previous scanning carriage on the paper cannot be scanned on the same path when it is transmitted to the next scanning carriage. This makes it impossible to reflect the actual situation when calculating the coating amount.

[0004] On the other hand, due to the distance between the two scanning frames, if the two scanning frames upload banner scanning data at the same time, the data uploaded is not the data of the same scanning trajectory, and there is a certain time difference. The trajectory corresponding to the banner data uploaded by the scanning frame at the front end of the paper machine will reach the scanning frame at the back end of the paper machine after a period of longitudinal movement and distance. Therefore, the data received at the same time cannot reflect the situation of the same scanning trajectory.

[0005] In view of this, this application is hereby filed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that when detecting the coating amount of paper, the scanning paths of different scanning frames relative to the paper are not the same, and there is a distance between the two scanning frames, which causes the data received at the same time to be unable to reflect the situation of the same scanning trajectory, thereby affecting the detection result. The purpose is to provide an operation synchronization and data synchronization method and system for the mobile carriages of multiple paper detection scanning frames, which can ensure that the banner curves scanned by multiple scanning frames are a unified scanning path trajectory relative to the paper, and at the same time eliminate the data misalignment caused by the installation distance between different scanning frames, and ensure that the data received by all scanning frames at the same time are banner data of the same scanning trajectory on the paper.

[0007] The present invention is achieved through the following technical solutions:

[0008] A method for synchronizing the operation and data of multiple paper inspection scanning frames, comprising multiple scanning frames 1, 2, 3, ..., k arranged in sequence along the same direction as the paper transport direction, wherein k is an integer greater than or equal to 2, and the paper first passes through scanning frame 1 and finally passes through scanning frame k;

[0009] The scanning frame is equipped with a movable carriage capable of reciprocating along a direction perpendicular to the paper transmission direction;

[0010] The distances between each scanning frame and scanning frame 1 are S1, S2, S3...S k-1 ;

[0011] The distance that the moving carriage transports the paper in one reciprocating motion is h;

[0012] The method for synchronizing the running trajectory of the mobile car includes the following steps:

[0013] (1) Start the moving carriage of scanning frame 1 and run it to the starting point of reciprocating motion, and record the time t11 when it reaches the starting point of reciprocating motion. At this time, scanning frames 2, 3, ..., k also run to the starting point of reciprocating motion and stop moving, and are in a standby state;

[0014] (2) After the moving carriage of the scanning frame 1 completes a complete reciprocating motion, the time t2 is immediately recorded, and the paper transmission distance h is calculated based on the difference between t2 and t1 and the paper transmission speed;

[0015] (3) Use S k-1 Divide by h to get the integer n k-1 and remainder a k-1 ;

[0016] (4) The moving carriage of the scanning frame 1 continues to reciprocate and records the movement time of the moving carriage of the scanning frame 1 at all times. When the paper transmission distance is calculated to be equal to a based on the difference between a certain moment and moment t2, k-1When the scanning frame k is immediately started, the moving carriage of the scanning frame k starts to reciprocate, so that the moving carriages of the scanning frame k and the scanning frame 1 are synchronized with each other in their running trajectories relative to the paper;

[0017] (5) Repeat the above operations to synchronize the running trajectories of all the moving carts relative to the paper.

[0018] Furthermore, the method for synchronizing the running trajectory data of the mobile vehicle includes the following steps:

[0019] When all the scanning frames start to reciprocate, it is recorded as cycle 1. The scanning frame saves the banner curve without uploading it until the nth k-1 +1 cycle starts, scanning frame k starts uploading the banner curve of the 1st cycle, scanning frame k-1 starts uploading the banner curve of the nth cycle. k-1 +1-n k-2 The banner curve of the cycle, scanning frame k-2 starts uploading the nth k-1 +1-n k -3 cycles of banner curves... Scanner 1 uploads the banner curve of the first cycle, and so on. At this time, the running trajectory data uploaded by all scanners are in a synchronized state.

[0020] Furthermore, when k is greater than 2, the scanning frames are 1, 2...k-1, k respectively, and the method for synchronizing the running trajectory of the mobile car specifically includes the following steps:

[0021] (1) Start the moving carriage of scanning frame 1 and run it to the starting point of reciprocating motion, and record the time t11 when it reaches the starting point of reciprocating motion. At this time, scanning frames 2, 3, ..., k also run to the starting point of reciprocating motion and stop moving, and are in a standby state;

[0022] (2) After the moving carriage of the scanning frame 1 completes a complete reciprocating motion, the time t2 is immediately recorded, and the paper transmission distance h is calculated based on the difference between t2 and t1 and the paper transmission speed;

[0023] (3) Divide S1 by h to obtain the integer n1 and the remainder a1;

[0024] (4) The moving carriage of scanning frame 1 continues to reciprocate, and the movement time of the moving carriage of scanning frame 1 is constantly recorded. When the paper transmission distance is equal to a1 according to the difference between a certain time and time t2, the moving carriage of scanning frame 2 is immediately started to reciprocate, so that the movement trajectories of the moving carriages of scanning frame 2 and scanning frame 1 relative to the paper are synchronized;

[0025] (5) Divide S2 by h to obtain the integer n2 and the remainder a2;

[0026] (6) The moving carriage of scanning frame 1 continues to reciprocate, and the movement time of the moving carriage of scanning frame 1 is constantly recorded. When the paper transmission distance is equal to a2 according to the difference between a certain time and time t2, the moving carriage of scanning frame 3 is immediately started to reciprocate, so that the moving trolleys of scanning frame 3 and scanning frame 1 are synchronized with each other in their running trajectories relative to the paper;

[0027] (7) Repeat steps (5)-(6) to synchronize the trajectory of all moving carriages with the moving carriage of the scanning frame 1 relative to the paper.

[0028] Furthermore, an incremental encoder is used to calculate the paper transmission distance. The incremental encoder is used to calculate the distance, which is not affected by changes in the paper machine's operating speed and is not affected by different paper transmission speeds at the scanning frame A and the scanning frame B.

[0029] Furthermore, the movable carriage is controlled by a servo motor to perform reciprocating motion, and the scanning frame movable carriage is controlled by the servo motor, with high precision and low delay.

[0030] Furthermore, the movement time of the mobile car is calculated using the arm chip of the scanning frame. When the scanning frame k is in the standby state, the scanning frame 1 calculates the start time of the scanning frame k according to the model. This part of the calculation uses the arm chip of the scanning frame, which is efficient and fast and can improve the accuracy of motion synchronization.

[0031] Furthermore, the scanning frame uses a Flash chip and stack structure to store banner curves without uploading them. Once the scanning frame starts running, it uses a large-capacity Flash chip and stack structure to store banner data. Once the paper area corresponding to the banner curve in the stack structure reaches another scanning frame, it retrieves the data and uploads it to the host computer, achieving data synchronization.

[0032] The present invention also provides a system for synchronizing the operation and data of multiple paper detection scanning frame moving carriages, including

[0033] A driving module, which is used to drive the moving carriage of the scanning frame to perform reciprocating motion;

[0034] A control module, which is used to send an operation command to the drive module to drive the corresponding mobile vehicle to operate;

[0035] A timing module, which is used to record the movement time of the mobile car;

[0036] A data processing module, configured to calculate the paper transmission distance at different times according to the signal sent by the timing module;

[0037] a judgment module, the judgment module being used to judge whether the paper transmission distance calculated by the data processing module reaches a certain value, and return the judgment structure to the control module;

[0038] The scanning module is used to scan the paper web area of ​​the moving vehicle's running track.

[0039] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0040] An embodiment of the present invention provides an operation synchronization and data synchronization method and system for a mobile carriage of multiple paper detection scanning frames, which can ensure that the banner curves scanned by the multiple scanning frames are a unified scanning path trajectory relative to the paper, while eliminating the data misalignment caused by the installation distance between different scanning frames, and ensuring that the data received by all scanning frames at the same time are banner data of the same scanning trajectory on the paper.

[0047] Example 1

[0048] An embodiment of the present invention provides a method for synchronizing the operation and data of multiple paper inspection scanning frame moving carriages, comprising two scanning frames 1 and 2 arranged in sequence in a direction opposite to the paper conveying direction, i.e., scanning frame 1 is installed at the front end of a paper machine, and scanning frame 2 is installed at the rear end of the paper machine;

[0049] The scanning frame is equipped with a trolley that moves horizontally and reciprocatingly, which is controlled by a servo motor. The trolleys of scanning frame 1 and scanning frame 2 have the same running speed and the same travel length.

[0050] An incremental encoder is installed on the guide roller in front of the scanning frame 1;

[0051] The signal generated by the encoder installed on the paper machine shaft when the paper machine is running is independent of the speed and time of the paper machine, so the encoder count can be used to measure the distance;

[0052] The setting distance between scanning frame 1 and scanning frame 2 is S;

[0053] The distance that the moving carriage transports the paper in one reciprocating motion is h;

[0054] The scanning frame 1 is the computing and control center of the entire system, and can receive the encoder signal installed on the paper machine shaft on the scanning frame 1;

[0055] In addition, it includes a host computer and host computer software running in the host computer, which can communicate with the scanning frame 1 and the scanning frame 2, control the operation of the scanning frame and receive scanning data of the scanning frame;

[0056] The method for synchronizing the trajectory and data of the mobile carriages of the two scanning frames includes the following steps:

[0057] (1) The scanning speed and scanning range of scanning frame 2 are synchronized with those of scanning frame 1 through the network protocol. The upper computer software sends an operation instruction to scanning frames 1 and 2. The mobile carriage of scanning frame 1 immediately leaves the warehouse and runs to the starting point of the reciprocating motion (usually the edge of the paper). After arriving, it sends a signal of reaching the starting point. After sending, it immediately starts the reciprocating scanning motion. After scanning frame 1 receives the signal of the scanning frame reaching the starting point, it records the encoder count t1 at this time. At this time, scanning frame 2 also runs to the starting point of the reciprocating motion and stops moving, and is in a standby state (scanning frame 2 stops at the edge of the paper and stands by, which can eliminate the influence of the distance from the warehouse position to the paper edge on the operation synchronization);

[0058] (2) After the moving carriage of scanner 1 completes a complete reciprocating motion and passes the starting point of the reciprocating motion, it immediately sends an arrival starting point signal, and scanner 1 immediately records the encoder count t2. The difference h between t2 and t1 is the distance h that the paper is transported during one cycle of the scanner.

[0059] (3) Dividing S by h yields an integer n and a remainder a, indicating that the distance between the two scanning frames is equal to the sum of n h distances and 1 a distance;

[0060] (4) At this time, the moving carriage of scanning frame 1 continues to reciprocate and the encoder count of the moving carriage of scanning frame 1 is recorded at all times. When the difference between the encoder count at a certain moment and the encoder count t2 is equal to a, the moving carriage of scanning frame 2 is immediately started to reciprocate, so that the moving carriages of scanning frame 1 and scanning frame 2 are synchronized with each other in their running trajectories relative to the paper.

[0061] (5) Starting from the reciprocating motion of the moving carriage of scanning frame 2, which is recorded as cycle 1, scanning frame 2 uploads the scanning curve every time, while scanning frame 1 uses a stack structure to save the banner curve without uploading it, until the beginning of the n+1th cycle, scanning frame 1 starts uploading from the banner curve of the first cycle, and uploads the data of the second cycle in the n+2th cycle, and so on. At this time, the data received by scanning frame 1 and scanning frame 2 at the same time are in a synchronized state, which is the banner data of the same motion trajectory on the paper.

[0062] (6) The host computer software receives the banner data uploaded by the two scanning frames and calculates the banner curve of the coating amount or moisture change.

[0063] Example 2

[0064] like Figure 1 As shown, an embodiment of the present invention provides a method for synchronizing the operation and data of multiple paper inspection scanning frame moving carriages, comprising three scanning frames 1, 2, and 3 arranged in sequence in a direction opposite to the paper conveying direction, i.e., scanning frame 1 is installed at the front end of a paper machine, scanning frame 2 is installed in the middle of the paper machine, and scanning frame 3 is installed at the end of the paper machine;

[0065] The scanning frame is equipped with a trolley that moves horizontally and reciprocatingly, which is controlled by a servo motor. The trolleys of scanning frames 1, 2 and 3 have the same running speed and the same travel length.

[0066] An incremental encoder is installed on the guide roller in front of the scanning frame 1, and the encoder signal is connected to the scanning frame 1;

[0067] The setting distance between scanning frame 1 and scanning frame 2 is S1, and the setting distance between scanning frame 1 and scanning frame 3 is S2;

[0068] The distance that the moving carriage transports the paper in one reciprocating motion is h;

[0069] In addition, a host computer and host computer software running in the host computer are included, which can communicate with scanning frame 1, scanning frame 2 and scanning frame 3, control the operation of the scanning frames and receive scanning data from the scanning frames;

[0070] The method for synchronizing the trajectory and data of the mobile carriages of the three scanning frames includes the following steps:

[0071] (1) The scanning speed and scanning range of scanning frames 2 and 3 are synchronized with those of scanning frame 1 through the network protocol. The upper computer software sends an operation instruction to scanning frames 1, 2 and 3. The mobile carriage of scanning frame 1 immediately leaves the warehouse and runs to the starting point of the reciprocating motion (usually the edge of the paper). After arriving, it sends a signal of reaching the starting point and immediately starts the reciprocating scanning motion. After receiving the signal of the scanning frame reaching the starting point, scanning frame 1 records the encoder count t1 at this time. At this time, scanning frame 2 also runs to the starting point of the reciprocating motion and stops moving, and is in a standby state (scanning frames 2 and 3 stop and wait at the edge of the paper, which can eliminate the influence of the distance from the warehouse position to the paper edge on the operation synchronization);

[0072] (2) After the moving carriage of scanner 1 completes a complete reciprocating motion and passes the starting point of the reciprocating motion, it immediately sends an arrival starting point signal, and scanner 1 immediately records the encoder count t2. The difference h between t2 and t1 is the distance h that the paper is transported during one cycle of the scanner.

[0073] (3) Dividing S1 by h yields the integer n1 and the remainder a1, indicating that the distance between scanning frame 1 and scanning frame 2 is equal to the sum of n1 distances h and 1 distance a1;

[0074] (4) At this time, the moving carriage of scanning frame 1 continues to reciprocate and the encoder count of the moving carriage of scanning frame 1 is recorded at all times. When the difference between the encoder count at a certain moment and the encoder count t2 is equal to a1, the moving carriage of scanning frame 2 is immediately started to reciprocate, so that the moving carriages of scanning frame 1 and scanning frame 2 are synchronized with the running trajectory relative to the paper;

[0075] (5) Dividing S2 by h yields the integer n2 and the remainder a2, indicating that the distance between scanning frame 1 and scanning frame 3 is equal to the sum of n2 distances h and 1 distance a2;

[0076] (6) At this time, the moving carriage of scanning frame 1 continues to reciprocate and the encoder count of the moving carriage of scanning frame 1 is recorded at all times. When the difference between the encoder count at a certain moment and the encoder count t2 is equal to a2, the moving carriage of scanning frame 3 is immediately started to reciprocate, so that the moving carriages of scanning frame 1 and scanning frame 3 are synchronized with respect to the running trajectory of the paper;

[0077] (7) From the beginning of the reciprocating motion of the moving carriage of scanning frame 3, which is recorded as cycle 1, scanning frame 1 uploads the scanning curve every time, while scanning frames 2 and 3 use a stack structure to save the banner curve without uploading; when the n2+1th cycle begins, scanning frame 3 starts uploading the banner curve of the n2+1th cycle, scanning frame 2 starts uploading the banner curve of the n2+1-n1th cycle, and scanning frame 1 starts uploading the banner curve of the 1st cycle. At this time, the data received by scanning frames 1, 2, and 3 at the same time are in a synchronized state, which is the banner data of the same motion trajectory on the paper;

[0078] (8) The host computer software receives the banner data uploaded by the three scanning frames and calculates the banner curve of the coating amount or moisture change.

[0079] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
