Description

Technical Field

[0001] The present invention relates to the field of control technology, and particularly to a printing device control system based on cloud computing. Background Art

[0002] In the era when digital office and life scenarios are becoming increasingly popular, printing needs are everywhere. Whether it is the output of document materials in enterprise offices, the printing of learning materials in school education scenarios, or the temporary printing needs in public places such as hotels and libraries, strict requirements are put forward for the convenience and efficiency of printing services. However, the current printing service field faces many difficult problems. On the one hand, when users face multiple printers distributed in different areas, they often lack effective guidance to choose the one closest to themselves. The traditional printing method simply lists the available printer lists, and users can only rely on visual observation or vague memory to judge which printer is closer to themselves. This not only takes a lot of time but also is extremely error-prone, resulting in users having to spend extra energy looking for the printer, greatly increasing unnecessary route time. Moreover, even if the printer is found, there are still many problems in setting printing preferences. Different printing tasks have diverse requirements for paper types, printing quality, color modes, etc., but most of the existing systems cannot conveniently allow users to set these preferences in advance. Users often need to manually adjust various settings in front of the printer, which is cumbersome and error-prone, further affecting the printing efficiency and greatly reducing the user experience. On the other hand, from the perspective of printer management and maintenance, the monitoring of printer speed is almost blank. For the providers of printing services, being unable to grasp the running speed of the printer in real time means that it is difficult to detect potential printer faults in advance. When the printer slows down due to problems such as wear of internal mechanical components, insufficient ink or toner in the cartridge, and jamming of the paper transmission system, due to the lack of effective monitoring means, these problems cannot be discovered and solved in time, resulting in the backlog of printing tasks and the infinite extension of the waiting time of subsequent users. This not only reduces the overall efficiency of the printing service but also brings a lot of inconvenience to users, seriously hindering the smooth progress of the printing process. Therefore, a printing device control system based on cloud computing is proposed. Summary of the Invention

[0003] The problem to be solved by the present invention is the problem that users have a poor experience due to the inability to select a printer nearby and set printing preferences, and the inability to monitor the printer speed, and a printing device control system based on cloud computing is provided.

[0004] The technical solution adopted by the present invention to solve its technical problems is:

[0005] A printing device control system based on cloud computing includes a printer speed detection module, an optimal recommendation module, and a remote control module.

[0006] The printer speed detection module is used to detect the average speed of the printer.

[0007] The best recommendation module is used to determine the location of the nearest printer.

[0008] The remote control module is used to control the printer.

[0009] Furthermore, the printer speed detection module is a cloud server.

[0010] The cloud server is connected to the cloud network and is used to read the historical data of N printers out of M printers from the cloud. Then, based on the printing time and the number of printed pages in the historical data of N printers out of M printers, the printing speeds of N printers out of M printers are calculated. Then, based on the printing speeds of N printers out of M printers, the average speed of M printers is calculated. And it is used to update the historical average speed of the printer stored in the cloud to the average speed of the printer after obtaining the average speed of M printers.

[0011] Furthermore, the formula for calculating the printing speeds of N printers out of M printers based on the printing time and the number of printed pages in the historical data of N printers out of M printers by the cloud server is:

[0012] where T i,j is the printing time in the j-th historical data of the i-th printer, with the unit of s, N i,j is the number of printed pages in the j-th historical data of the i-th printer, with the unit of Page, V i,j is the printing speed in the j-th historical data of the i-th printer, with the unit of Page / s, j ∈ [1, N].

[0013] The formula for calculating the average speed of M printers based on the printing speeds of N printers out of M printers is:

[0014] where, is the average speed of the i-th printer, with the unit of Page / s.

[0015] Furthermore, the best recommendation module includes a mobile terminal and a navigation unit.

[0016] The cloud server is used to transmit the average speed of M printers to the mobile terminal after obtaining it.

[0017] The navigation unit is connected to the mobile terminal through the network and is used for the user to use the navigation function and obtain the user's location. Then, it detects the current user speed and transmits the user's location and the current user speed to the mobile terminal. The navigation unit is a navigator.

[0018] The mobile terminal is connected to the cloud server and the cloud network, and is used for the user to set the number of printed pages. And it is used to view the printer locations stored in the cloud after receiving the average speed of the printer. After receiving the user location and the current user speed, it calculates the distances between the user location and M printer locations based on the user location and the M printer locations, then calculates the printing time based on the number of printed pages set by the user and the average speed of the printer, then calculates M arrival times based on the distances between the user location and the M printer locations and the current user speed, then traverses and calculates the optimal distance time based on the M arrival times and the printing time, and finally marks and displays the printer location corresponding to the optimal distance time.

[0019] Further, the formula for the mobile terminal to calculate the distances between the user location and M printer locations based on the user location and the M printer locations is:

[0020]

[0021] where d is the distance between the user location and the i-th printer, in meters, r is the radius of the earth, in meters, is the latitude of the user location, in degrees, is the latitude of the i-th printer location, in degrees, λ 1 is the longitude of the user location, in degrees, λ i is the longitude of the i-th printer location, in degrees, Δλ i is the radian difference of the longitude difference between the user location and the i-th printer location, in degrees, is the radian difference of the latitude between the user location and the i-th printer location, in degrees, i ∈ [1, M].

[0022] Further, the formula for the mobile terminal to calculate the printing time based on the number of printed pages set by the user and the average speed of the printer is:

[0023]

[0024] where N is the number of printed pages set by the user, in pages, T printi is the printing time of the i-th printer, in s, is the average speed of the printer, in pages / s, i ∈ [1, M]

[0025] The formula for calculating M arrival times based on the distances between the user location and M printer locations and the current user speed is:

[0026]

[0027] where V user is the current user speed, in m / s, T i，arriveis the arrival time at the i-th printer, in seconds, where i ∈ [1, M].

[0028] Furthermore, the formula for the mobile terminal to traverse and calculate the optimal distance time based on the M arrival times and printing times is:

[0029] T best = min(T 1，arrive + T print1 , …, T i，arrive + T printi , … T Marrive + T printM ),

[0030] where T best is the optimal distance time, in seconds.

[0031] Furthermore, the remote control module is a control unit and an automatic setting unit.

[0032] The mobile terminal is used for the user to set printer preferences and then transmit them to the automatic setting unit. And it is used to transmit the printer position corresponding to the optimal distance time to the automatic setting unit and transmit the printer position corresponding to the optimal distance time and the arrival time corresponding to the optimal distance time to the control unit after obtaining the optimal distance time. The print setting preferences include print quality, color mode, single-sided / double-sided printing, scaling ratio, and paper type.

[0033] The automatic setting unit is network-connected to the navigation unit and the mobile terminal. It is used to adjust the setting preferences of the printer corresponding to the optimal distance time according to the print setting preferences after receiving the print setting preferences and the printer position corresponding to the optimal distance time. The automatic setting unit is a server.

[0034] The control unit is network-connected to the navigation unit, the mobile terminal, and the printer. It is used to compare the arrival time corresponding to the optimal distance time with the cleaning printer head time, paper preheating time, and cleaning and maintenance time in the preset time-judgment instruction table after receiving the printer position corresponding to the optimal distance time and the arrival time corresponding to the optimal distance time, and obtain the final control instruction, and then control the printer according to the final control instruction.

[0035] Furthermore, the control unit is a microcontroller.

[0036] Furthermore, the formula for the control unit to compare the arrival time corresponding to the optimal distance time in the preset time-judgment instruction table and obtain the final control instruction is:

[0037]

[0038] where T adjust 、T warm, T clean are respectively the cleaning printer head time, paper preheating time, cleaning and maintenance time in the preset time-judgment instruction table, with the unit of s, adjust printhead , warm paper , Clean machine respectively correspond to the cleaning printer head instruction, paper preheating instruction, cleaning and maintenance instruction in the preset time-judgment instruction table, I control is the final control instruction, T best，arrive is the arrival time corresponding to the optimal distance time, with the unit of s

[0039] Advantages of the present invention:

[0040] 1. The printer speed detection module ensures the long-term operation of the printer. It ensures that the average printer speed can be quickly updated to the cloud and immediately affects the subsequent decision-making process. By synchronizing data with the cloud, the printer speed detection module can provide accurate and real-time printer status data for other modules, improving the overall system coordination efficiency.

[0041] 2. The optimal recommendation module can accurately calculate the optimal distance time and printing time by combining the number of printed pages set by the user, the average speed of the printer, the current location and speed of the user, and can also meet the personalized needs of the user, thereby optimizing the user's printing experience. The calculation results can adjust the printer position according to the user's needs, reducing the user's waiting time and route time. Based on the real-time user location and printer status, the optimal recommendation module can provide dynamically updated printer selection and navigation solutions to ensure that users can select the most suitable printer, improve printing efficiency, and reduce unnecessary time waste.

[0042] 3. The remote control module can automatically execute judgment instructions to ensure that the printer is always in the best working state. By automatic control and adjustment, the printing efficiency is improved. Description of the Drawings

[0045] The following will clearly and completely describe the concept and technical effects generated by the present invention in combination with embodiments to fully understand the purpose, features and effects of the present invention. Please refer to Figure 1 , Figure 2 ,

[0046] A printing device control system based on cloud computing, including a printer speed detection module, an optimal recommendation module, and a remote control module.

[0047] The printer speed detection module is used to detect the average speed of the printer.

[0048] The optimal recommendation module is used to determine the location of the nearest printer.

[0049] The remote control module is used to control the printer.

[0050] In this embodiment, the printer speed detection module is a cloud server.

[0051] The cloud server is connected to the cloud network and is used to read the historical data of N out of M printers from the cloud, calculate the printing speeds of N historical data of M printers based on the printing time and the number of printed pages in the N historical data of M printers, and then calculate the average speed of M printers based on the N printing speeds of M printers. And it is used to update the historical average speed of the printer stored in the cloud to the average speed of the printer after obtaining the average speed of M printers.

[0052] The cloud is a server cluster, which internally stores the historical data of the printer. The historical data includes the printing time, the number of printed pages, and the printer location. The cloud server transmits the average speed of the printer to the cloud and updates the historical average speed of the printer in the historical data stored in the cloud to the average speed of the printer.

[0053] In this embodiment, the formula for the cloud server to calculate the printing speeds of N historical data of M printers based on the printing time and the number of printed pages in the N historical data of M printers is:

[0054] Where T i,j is the printing time in the j-th historical data of the i-th printer, with the unit of s, N i,j is the number of printed pages in the j-th historical data of the i-th printer, with the unit of Page, V i,j is the printing speed in the j-th historical data of the i-th printer, with the unit of Page / s, j ∈ [1, N].

[0055] The formula for calculating the average speed of M printers based on the N printing speeds of M printers is:

[0056] Where, is the average speed of the i-th printer, with the unit of Page / s.

[0057] In this embodiment, the optimal recommendation module includes a mobile terminal and a navigation unit.

[0058] The cloud server is used to transmit the average speed of M printers to the mobile terminal after obtaining it.

[0059] The navigation unit is connected to the mobile terminal through the network. It is used for the user to use the navigation function, obtain the user's location, detect the current user speed, and then transmit the user's location and the current user speed to the mobile terminal. The navigation unit is a navigator.

[0060] The mobile terminal is connected to the cloud server and the cloud network. It is used for the user to set the number of printing pages. And it is used to view the locations of the printers stored in the cloud after receiving the average speed of the printers. It is used to calculate the distances between the user's location and the M printer locations based on the user's location and the M printer locations after receiving the user's location and the current user speed. Then calculate the printing time based on the number of printing pages set by the user and the average speed of the printers. Then calculate the M arrival times based on the distances between the user's location and the M printer locations and the current user speed. Then traverse and calculate the best distance time based on the M arrival times and the printing time. Then mark and display the printer location corresponding to the best distance time. The mobile terminal uses a smartphone.

[0061] In this embodiment, the formula for the mobile terminal to calculate the distances between the user's location and the M printer locations based on the user's location and the M printer locations is:

[0062]

[0063] where d is the distance between the user's location and the i-th printer, in meters, r is the radius of the earth, in meters, is the latitude of the user's location, in degrees, is the latitude of the i-th printer location, in degrees, λ 1 is the longitude of the user's location, in degrees, λ i is the longitude of the i-th printer location, in degrees, Δλ i is the difference in longitude between the user's location and the i-th printer location converted to a difference in radians, in degrees, is the difference in latitude between the user's location and the i-th printer location converted to a difference in radians, in degrees, i ∈ [1, M].

[0064] For example, if the user's location is (39.9042°N, 116.4074°E), the i-th printer location is (39.9085°N, 116.3989°E), the radius of the earth is 6371 km, the difference in longitude between the user's location and the i-th printer location converted to a difference in radians is -0.000155 rad, and the difference in latitude between the user's location and the i-th printer location converted to a difference in radians is 0.000079 rad, then the distance between the user's location and the i-th printer is 20 m.

[0065] In this embodiment, the formula for the mobile terminal to calculate the printing time based on the number of pages to be printed set by the user and the average speed of the printer is:

[0066]

[0067] where N is the number of pages to be printed set by the user, with the unit of page, and T printi is the printing time of the i-th printer, with the unit of s, is the average speed of the printer, with the unit of page / s, and i ∈ [1, M]

[0068] The formula for calculating M arrival times based on the distance between the user's location and M printers and the current user speed is:

[0069]

[0070] where V user is the current user speed, with the unit of m / s, and T i，arrive is the arrival time to the i-th printer, with the unit of s, and i ∈ [1, M].

[0071] For example, T print1 = 10 s, N is 50 pages, is 5 m / s.

[0072] For example, V user is 2 m / s, d 1 is 20 m, and T 1，arrive is 50 s.

[0073] In this embodiment, the formula for the mobile terminal to traverse and calculate the optimal distance time based on M arrival times and printing times is:

[0074] T best = min(T 1，arrive + T print1 , …, T i，arrive + T printi , … T Marrive + T printM ),

[0075] where T best is the optimal distance time, with the unit of s.

[0076] In this embodiment, the remote control module is a control unit and an automatic setting unit,

[0077] The mobile terminal is used for the user to set printer preferences and then transmit them to the automatic setting unit. And it is used to transmit the printer position corresponding to the optimal distance time to the automatic setting unit after obtaining the optimal distance time, and transmit the printer position corresponding to the optimal distance time and the arrival time corresponding to the optimal distance time to the control unit. The print setting preferences include print quality, color mode, single-sided / double-sided printing, scaling ratio, and paper type.

It is used to compare the arrival time corresponding to the optimal distance time with the cleaning printer head time, paper preheating time, and cleaning and maintenance time in the preset time-judgment instruction table after receiving the printer position corresponding to the optimal distance time and the arrival time corresponding to the optimal distance time, and obtain the final control instruction. Then, it controls the printer according to the final control instruction.

[0080] The preset time-judgment instruction table is as follows:

[0081] Condition <![CDATA[I control value]]> <![CDATA[T adjust <T best,arite <T warm > <![CDATA[adjust printhead (Cleaning printer head instruction)]]> <![CDATA[T warm <T best，arrive <T clean > <![CDATA[warm paper (Paper preheating instruction)]]> <![CDATA[T best，arrive > T clean > <![CDATA[Clean machine (Cleaning and maintaining machine instructions)]]>

[0082] In this embodiment, the control unit is a microcontroller.

[0083] In this embodiment, the formula for the control unit to compare the arrival time corresponding to the optimal distance time in the preset time-judgment instruction table and obtain the final control instruction is:

[0084]
