In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The method for automatically adjusting the printing speed in the embodiment of the present application is applied to a distributed printing system.

Please refer to FIG. 1, the distributed printing system 10 in the embodiment of the present application specifically includes:

Main control host 101; the main control host can be connected with a paper feeding platform 106

The imaging component control host 102 is connected to the main control host 101;

The second high-speed transmission system 105 is connected between the imaging component control host 102 and the imaging component 103, and is used for the imaging component control host 102 to send the dot matrix data to the imaging component 103;

The imaging component control host 102 includes:

An input unit 1021, configured to obtain compressed data to be printed from the main control host 101;

The host control unit 1022 is configured to process the compressed data to be printed to obtain dot matrix data;

A monitoring unit 1025, connected to the storage unit 1023, for monitoring the data volume of the dot matrix data in the storage unit 1023;

Wherein, the host control unit 1022 will send the data storage status to the main control host 101 after receiving the data storage status monitored by the monitoring unit 1025;

Wherein, the paper speed adjustment instruction is specifically an instruction generated by the main control host 101 when judging that the data volume of the dot matrix data in the storage unit 1023 is not within a preset range.

Next, the method for automatically adjusting the printing speed in the embodiment of the present application will be described in detail with reference to FIG. 1 and FIG. 2 . Specifically, the following steps are included:

Step 201: Perform initial settings on the distributed printing system 10

Further, the specific steps of step 201 include:

Set a preset range for the amount of data that can be stored in the storage unit 1023 of the distributed printing system 10, such as: the total amount of data that can be stored in the storage unit 1023 is M, when the storage unit 1023 stores When the dot matrix data is between 35%M-65%M, the data receiving and sending of the storage unit 1023 is kept in a balanced state, then 35%M-65%M at this time is the preset range Of course, this is just an example. In the specific implementation process, the confirmation of the preset range value of the amount of data that can be stored in the storage unit 1023 is relatively complicated, and a reasonable value needs to be determined according to the overall performance of the entire distributed printing system. The preset range value can be determined by means of software, for example, the program calculates an optimal preset range value according to a preset performance strategy, or an empirical value can be determined through human experience.

Set a maximum paper speed and a minimum paper speed for the paper speed, for example: the maximum paper speed of the distributed printing system can be set to 100m/min, and the minimum paper speed is 20m/min.

After completing the initial setting of the distributed printing system 10 through step 201, the method in the embodiment of the present application enters into step 202, that is: the main control host 101 sends a compressed image to be printed to the imaging component control host 102 The data is sent to the imaging component control host 102. The compressed data to be printed here is specifically: the data to be printed is compressed using a certain compression ratio to form data, and the specific compression ratio can be determined according to the specific data to be printed. The situation is set, but the compression is performed based on the principle of ensuring no data loss.

In a specific implementation process, the specific implementation manner of step 202 is: implementation through the first high-speed transmission system 104 .

Specifically, the first high-speed transmission system 104 can be implemented in the form of hardware, for example, it can be: a data line with data transmission function connecting the main control host 101 and the imaging component control host 102, or it can be implemented in software, such as with data The wireless network protocol of the transmission function; the applicant will not limit what kind of transmission system the first high-speed transmission system 104 is, as long as it has a data transmission function, it should be included in the scope of the first high-speed transmission system 104 of the present invention.

After step 202 is executed, the method in the embodiment of the present application enters step 203, that is, the imaging component control host 102 processes the compressed data to be printed, obtains dot matrix data, and stores the dot matrix data in In the storage unit 1023 of the imaging component control host 102, for example, the above-mentioned data to be printed after being compressed with a certain compression ratio is sent by the main control host 101 to the imaging component control host 102, and the imaging component control host 102 The compressed data is processed to obtain dot matrix data. In specific implementation, the data is generally processed automatically by means of software, such as using C++, JAVA to write a program that processes data into dot matrix data to obtain compressed data. The dot matrix data, and the whole process of obtaining dot matrix data is completed by the host control unit 1022 in the imaging component control host 102. After the dot matrix data is obtained, it is still controlled by the host control unit 1022, and the obtained dot matrix data is stored to storage unit 1023.

After the dot matrix data is stored in the storage unit 1023 of the imaging component control host 102 in step 203, the method in the embodiment of the present application enters step 204, that is: the imaging component control host 102 stores the dot matrix data During the process of sending the dot matrix data from the storage unit 1023 to the imaging component 103, the main control host 101 judges whether the data volume of the dot matrix data in the storage unit 1023 is within a preset range, and obtains a critical result.

In a specific implementation process, the specific process of step 204 is: in the process of the imaging component control host 102 sending the dot matrix data from the storage unit 1023 to the imaging component 103, the monitoring unit 1025 monitors the storage unit 1023 The storage situation of the amount of dot matrix data, and the monitored storage situation is sent to the main control host 101 through the first high-speed transmission system 104, and the main control host 101 judges the storage unit 1023 according to the preset range preset in step 201 Whether the data volume of the dot matrix data exceeds the preset range, and obtain a judgment result.

For example, the above-mentioned preset range is 35%M-65%M, and when the amount of data stored in the storage unit 1023 is 20%M, the monitoring unit 1025 will send the monitored storage situation through the first high-speed transmission system 104 to The main control host 101, the main control host 101 will judge that the data volume of the dot matrix data is not within the preset range according to the preset range of 35%M-65%M; and when the data stored in the storage unit 1023 When the amount is 45%M, the monitoring unit 1025 also sends the monitored storage situation to the main control host 101 through the first high-speed transmission system 104, and then the main control host 101 according to the preset range of 35%M-65%M It is judged that the amount of data of the dot matrix data is within the preset range; similarly, when the amount of data stored in the storage unit 1023 is 80%M, the first control host 101 will be based on 35%M-65% M's preset range judges that it is not within the preset range.

After obtaining the judgment result in step 204, the method in the embodiment of the present application enters step 205, that is, when the judgment result shows that the amount of data is not within the preset range, the main control host 101 A paper-feeding speed adjustment instruction is generated for execution by the paper-feeding platform 106 .

In the specific implementation process, after the main control host 101 generates the paper-feeding speed adjustment instruction in step 205, the paper-feeding speed of the distributed printing system does not necessarily change, and whether the paper-feeding speed changes depends on The comparison between the current paper speed of the system and the maximum or minimum paper speed of the system, in order to better understand this step, will be described in detail below.

Specifically, there is another situation in the judgment result obtained, that is, when the judgment result shows that the data volume is within the preset range, the imaging component control host 102 will pass through the second high-speed transmission system 105 to send the dot matrix data to the imaging component 103. For example, when the amount of data stored in the storage unit 1023 is 45%M in the foregoing, the main control host 101 will judge that the amount of data is within the preset range. , the imaging unit control host 102 will send the dot matrix data to the imaging unit 103 through the second high-speed transmission system 105 , where the dot matrix data sent is the dot matrix data stored in the storage unit 1023 .

More specifically, when the obtained judgment result shows that the data volume is not within the preset range, the main control host 101 will judge whether it is necessary to increase the paper-feeding speed, and if it is necessary to increase the paper-feeding speed, obtain the system's The current paper-feeding speed, and comparing the current paper-feeding speed with the maximum paper-feeding speed, if the current paper-feeding speed is less than the maximum paper-feeding speed, the main control host 101 generates the paper-feeding speed Adjusting instructions for execution by the paper transport platform 106; for example, when the amount of data stored in the storage unit 1023 in the foregoing is 20%M, it indicates that the amount of data is not within the preset range of 35%M-65%M , since 20%M is less than 35%M, the main control host 101 will judge that it is necessary to increase the paper feeding speed, then the system will obtain the current paper feeding speed, and compare it with the preset maximum paper feeding speed of 100m/min, If the current paper-feeding speed is less than the maximum paper-feeding speed, the main control host 101 generates a paper-feeding speed adjustment command for execution by the paper-feeding platform 106; for example, the acquired current paper-feeding speed is 70m /mim, the main control host 101 will generate an adjustment instruction for increasing the paper-feeding speed for the paper-feeding platform 106 to execute.

If the current paper-feeding speed is equal to or exceeds the maximum paper-feeding speed, the dot matrix data is sent to the imaging component 103 through the second high-speed transmission system 105, for example, the acquired current paper-feeding speed is 100 m/min or 120 m/min, the dot matrix data is sent to the imaging component 103 through the second high-speed transmission system 105 .

Specifically, when the judging result shows that the data volume is not within the preset range, and the main control host 101 judges that it is not necessary to increase the paper feeding speed, it means that the paper feeding speed needs to be reduced, and the paper feeding speed still needs to be reduced. Obtain the current paper-feeding speed of the system, and compare the current paper-feeding speed with the minimum paper-feeding speed, if the current paper-feeding speed is greater than the minimum paper-feeding speed, the main control host 101 generates Paper-feeding speed adjustment instruction for execution by the paper-feeding platform 106; for example, when the amount of data stored in the storage unit 1023 in the foregoing is 80%M, it indicates that the amount of data is not within the preset range of 35%M-65 Within %M, since 80%M is greater than 65%M, the main control host 101 will judge that it is necessary to reduce the paper feeding speed, then the system will obtain the current paper feeding speed and compare it with the preset minimum paper feeding speed of 20m/min For comparison, if the current paper-feeding speed is greater than the minimum paper-feeding speed of 20m/min, the main control host 101 generates a paper-feeding speed adjustment instruction for execution by the paper-feeding platform 106; for example, to obtain If the current paper-feeding speed is 30 m/min, the main control host 101 will generate an adjustment command to reduce the paper-feeding speed for the paper-feeding platform 106 to execute.

If the current paper-feeding speed is equal to or less than the minimum paper-feeding speed, the dot matrix data is sent to the imaging component 103 through the second high-speed transmission system 105, for example, the acquired current paper-feeding speed is 20m/min or 10 m/min, the dot matrix data is sent to the imaging component 103 through the second high-speed transmission system 105 .

In a specific implementation process, the dot matrix data sent to the imaging component 103 through the second high-speed transmission system 105 will follow the principle of first-in first-out.

In order to better understand the implementation process of the adjustment of the paper feeding speed in this application, the following is a specific implementation process of a separate paper feeding speed adjustment to specifically illustrate the flow chart of the automatic adjustment of the paper feeding speed of the distributed printing system, specifically as follows As shown in Figure 3, the specific steps are:

Step 11: the storage unit 1023 receives the dot matrix data, and sends the dot matrix data to the imaging unit 103 if the imaging unit 103 can receive the dot matrix data.

Step 12: The monitoring unit 1025 monitors the storage of the dot matrix data in the storage unit 1023, and if the data volume of the dot matrix data stored in the storage unit 1023 remains within a preset preset range, go to step 17.

If the dot matrix data stored in the storage unit 1023 is not within the preset range preset by the system, go to step 13 .

Step 13: Determine whether the paper feeding speed of the system needs to be increased, if yes, go to step 14.

Otherwise, it is necessary to reduce the paper feeding speed of the system, then go to step 15.

Step 14: Obtain the current paper-feeding speed of the system, and compare it with the maximum paper-feeding speed of the system. If the current paper-feeding speed has reached the maximum paper-feeding speed of the system, go to step 17.

If the current paper-feeding speed is lower than the maximum paper-feeding speed of the system, go to step 16.

Step 15: Obtain the current paper-feeding speed of the system and compare it with the minimum paper-feeding speed of the system. If the current speed has reached the minimum paper-feeding speed, go to step 17.

If the current paper-feeding speed of the system is greater than the minimum paper-feeding speed of the system, go to step 16.

Step 16: Adjust the current paper feeding speed of the system to increase or decrease the speed.

Step 17: The current paper feeding speed of the system remains unchanged, and the dot matrix data is sent to the host computer 103 of the imaging component through the second high-speed transmission system 105 .
