Description

Technical Field

[0001] The invention relates to the field of printing technology, and in particular to an ink cartridge ink level prompting and early warning method, an ink cartridge chip and an ink cartridge. Background Art

[0002] The ink level prompting technology of the printer ink cartridge is a key function, which is used to remind the user of the remaining amount of ink in the ink cartridge to ensure the continuous progress of the printing task. In the invention with application number 201210006505.X, the present invention provides an ink cartridge ink level prompting and warning method, an ink cartridge chip, an ink cartridge and an imaging device. The ink cartridge ink level prompting method includes: comparing the remaining ink level of the ink cartridge with a preset ink level threshold value; if the remaining ink level is less than the threshold value, setting the analog sensor output signal of the ink cartridge to a first signal; the first signal is used to indicate that the ink cartridge is currently in an ink shortage state; and outputting the first signal to the imaging device connected to the ink cartridge. The present invention can achieve compatibility between a universal ink cartridge that is not provided with an actual sensor for monitoring the ink level of the ink cartridge and an imaging device at a relatively low cost.

[0003] However, when setting the threshold for reminding about the ink level, the invention only "compares the remaining ink level in the ink cartridge with the preset ink level threshold value", which is not smart enough. Many large printers have high requirements for printing quality, and they need to be prompted in advance of insufficient ink level when printing to avoid a decrease in printing quality due to running out of ink. The invention cannot predict the usage time of the remaining ink based on the ink usage speed of the current task, and cannot prompt in advance of insufficient ink level, resulting in unstable printing quality.

[0004] In order to block light, protect ink and regulate the temperature inside the ink cartridge, the entire surface of the ink cartridge is black. When adding ink or using ink, it is impossible to distinguish the ink content in the cartridge. During the printing process, whether it is overflow and waste when adding ink, or printing is interrupted due to running out of ink, it will cause inconvenience to the user and affect the print quality. At the same time, the performance of the ink cartridge is also a key factor in determining print quality. Summary of the invention

[0005] Technical issues solved

[0006] In view of the deficiencies in the prior art, the present invention provides an ink level prompt and warning method for an ink cartridge, an ink cartridge chip and an ink cartridge, which solve the technical problems mentioned in the above background technology.

[0007] Technical Solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for prompting and warning the ink level of an ink cartridge, comprising the following steps:

[0009] Step 1: Evaluate the ink cartridge performance, collect the bubble area Nbq in the ink cartridge, the ink cartridge nozzle blockage area Mdm and the air tightness Qmx, and calculate and obtain the ink cartridge index Mhz, and evaluate the ink cartridge index Mhz;

[0010] Step 2: deploying an identification reminder component on the surface of the ink cartridge to remind the user of the current state of the ink in the ink cartridge through an LED reminder light in the identification reminder component;

[0011] Step 3: Install the ink cartridge and start printing. During the printing process, the weight of the solid ink after each task is completed is recorded by the pressure sensor, and the ink flow speed Zms is calculated according to the remaining weight of the solid ink;

[0012] Step 4: Compare the preset ink flow threshold value A3 with the ink flow speed Zms to generate a first result and a second result respectively, and then generate different prompts and warnings according to the first result and the second result respectively.

[0013] Preferably, the bubble area Nbq in the ink cartridge is photographed or observed by an optical imaging device, and the bubble area Nbq in the ink cartridge is identified and quantified by an image processing algorithm, indicating the air bubbles present in the ink cartridge;

[0014] The nozzle blockage area Mdm indicates the area where the ink cartridge nozzle is partially blocked. The ink cartridge nozzle is photographed or observed using a high-resolution camera, and the blocked area on the nozzle surface is identified and quantified through an image processing algorithm, thereby calculating the nozzle blockage area Mdm.

[0015] Air tightness Qmx monitors the air pressure changes in the ink cartridge through the air pressure sensor. In a closed state, if the air tightness inside the ink cartridge is good, the air pressure should not change significantly; indicating whether the inside of the ink cartridge is completely sealed and no gas leakage or penetration will occur;

[0016] After the bubble area Nbq, the cartridge nozzle blockage area Mdm and the air tightness Qmx are dimensionlessly processed, the cartridge index Mhz is calculated using the following formula:

[0017]

[0018] The preset performance threshold A1 and the cartridge index Mhz are evaluated to generate the following results and solutions:

[0019] If the performance threshold A1> the ink cartridge index Mhz, it means that the current ink cartridge performance is normal and it can be used and refilled after adjustment;

[0020] If the performance threshold A1 ≤ the ink cartridge index Mhz, it means that the current ink cartridge performance is abnormal and cannot be adjusted further. It is necessary to replace a new ink cartridge and then continue to add ink.

[0021] Preferably, the identification reminder component includes a pressure sensor, a processing chip and an LED prompt light. The pressure sensor and the processing chip are installed inside the ink cartridge, and the LED prompt light is installed on the surface of the ink cartridge. The LED prompt light has three colors, namely red, yellow and green. The reminder threshold of the pressure sensor is set according to the pressure value of the pressure sensor exerted by the ink weight in a saturated state. When ink is added to the ink cartridge, the ink in the ink cartridge continuously applies pressure to the pressure sensor until the reminder threshold is reached, at which time the pressure sensor sends a signal, which is received and processed by the processing chip, and the LED prompt light turns on green to remind the user that the ink is full.

[0022] Preferably, the ink applies pressure to the pressure sensor on the surface of the ink cartridge, thereby calculating the remaining amount of ink after each printing task is completed, and then obtaining the ink usage ΔM after each printing task is completed by differential calculation. t , ΔM t =M t -M t-1 ;M t represents the first ink change after the tth task, M t-1 represents the second ink change in the t-1th cycle; and according to the ink usage ΔM after each printing task is completed t , construct a time-series ink usage change set; construct the absolute value of each ink usage change, and issue a change instruction when each ink usage exceeds the change threshold A2.

[0023] Preferably, according to the ink usage ΔM after each printing task is completed t , the first ink change after a printing task is completed is calculated by the following formula The second ink change after the last printing task is completed Represents the ink volume change trend under sequential printing tasks:

[0024]

[0025] And a number of first ink change amounts The second ink change amount of the previous print task Create a time series ink volume change set and make the following records: in, represents the absolute value of the ink volume change after the jth printing task is completed, and The ink volume is compared with the change threshold A2 respectively. If it exceeds the change threshold A2, it means that the change of each printing ink volume is abnormal, and the first instruction is generated; if it does not exceed the change threshold A2, it means that the change of each printing ink volume is stable and there is no abnormality.

[0026] Preferably, the pressure sensor records the remaining amount of ink after each printing task is completed by gradually reducing the ink pressure, until the remaining amount of ink is 75% of the total amount, then stops recording and starts calculating the current ink flow speed;

[0027] The ink flow speed is calculated by the following formula:

[0028]

[0029] In the formula, Ysj is the average time, which means the average completion time of the printing task per hour, and B is the correction constant;

[0030] By comparing the preset ink flow threshold A3 with the ink flow speed Zms, the following results are generated:

[0031] If the ink flow threshold value A2> the ink flow speed Zms, it means that the current ink flow speed is slow, and the first result is generated;

[0032] If the ink flow threshold value A2 ≤ the ink flow speed Zms, it means that the current ink flow speed is fast, and the second result is generated.

[0033] Preferably, when the ink flow speed is slow and the first result is generated, the prompt threshold of the ink cartridge remaining amount is adjusted to: the remaining ink pressure weight is 15% of the total ink pressure weight, at which time the LED prompt light turns yellow to remind;

[0034] When the ink flow speed is fast and the second result is generated, the prompt threshold of the ink cartridge remaining amount is adjusted to: the remaining ink pressure weight is 25% of the total ink pressure weight, at which time the LED prompt light turns yellow to remind;

[0035] When there is no ink left in the ink cartridge, the LED indicator will light up red to remind you to refill the ink.

[0036] Preferably, an ink cartridge chip comprises:

[0037] An identification module is used to identify the ink pressure in the ink cartridge through a pressure sensor and provide a prompt;

[0038] The ink flow evaluation module is used to record the change of the ink pressure value after each task is completed through the pressure sensor, and calculate and evaluate the ink flow speed Zms according to the change of the ink pressure value, and generate a first result and a second result at the same time;

[0039] Adjust the module to adjust the threshold value of the yellow LED indicator light according to the ink feeding speed Zms;

[0040] When the pressure sensor cannot identify the ink pressure, it means the ink is used up. At this time, the chip will identify it and send a signal to make the LED indicator light red.

[0041] Preferably, the processing chip is used to receive analog signals from the pressure sensor, convert them into digital signals using analog signal processing technology, perform filtering, amplification and noise reduction, capture and analyze changes in pressure values, and the processing chip is also responsible for setting the reminder threshold of the pressure sensor. The processing chip uses a specific signal processing algorithm to analyze the changing pattern of the pressure value, including identifying the trend of the pressure value. Once the processing chip determines the status of the ink, it controls the output of the LED prompt light and sends a control signal to the LED prompt light through the digital output pin to make it light up the corresponding color.

[0042] An ink cartridge includes an ink cartridge body, including:

[0043] The ink cartridge performance evaluation module collects the bubble area Nbq in the ink cartridge, the ink cartridge nozzle blockage area Mdm and the air tightness Qmx, obtains the ink cartridge index Mhz through calculation, and evaluates the ink cartridge index Mhz to determine the ink cartridge performance, and maintains or replaces the ink cartridge according to the evaluation results;

[0044] Component deployment module, deploying identification reminder components on the surface of the ink cartridge, including pressure sensors, processing chips and LED prompt lights. The amount of ink in the ink cartridge is estimated by the pressure value exerted by the ink on the pressure sensor, and then the processing chip sends a signal to the LED prompt light. The LED prompt light emits red, yellow and green lights according to the received signals, so as to remind the user of the three situations of full ink, early ink replenishment and ink exhaustion;

[0045] The acquisition and calculation module collects the ink pressure after each task is completed through the pressure sensor during the printing process, and then obtains the ink usage ΔM after each printing task is completed through differential calculation. t , and collect the average time Ysj used for printing tasks per hour, and obtain the ink speed Zms through correlation calculation;

[0046] A speed evaluation module, which generates a first evaluation result and a second evaluation result respectively by presetting an ink running threshold value A3 and an ink running speed Zms;

[0047] The threshold adjustment module adjusts the reminder threshold of the LED prompt light according to the first evaluation result and the second evaluation result, and the LED prompt light turns on yellow light to remind the user to replenish ink in advance; when the ink is used up, the LED prompt light turns on red light.

BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Figure 1 A schematic diagram of a flow chart of an ink cartridge ink level prompt and warning method of the present invention;

[0053] Figure 2 The present invention is a schematic diagram of the structure of an ink cartridge. DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Example 1

[0056] See also Figure 1 The present invention provides an ink cartridge ink level prompt and warning method, comprising the following steps:

[0057] Step 1: Evaluate the ink cartridge performance, collect the bubble area Nbq in the ink cartridge, the ink cartridge nozzle blockage area Mdm and the air tightness Qmx, and calculate and obtain the ink cartridge index Mhz, and evaluate the ink cartridge index Mhz;

[0058] Step 2: deploying an identification reminder component on the surface of the ink cartridge to remind the user of the current state of the ink in the ink cartridge through an LED reminder light in the identification reminder component;

[0059] Step 3: Install the ink cartridge and start printing. During the printing process, the weight of the solid ink after each task is completed is recorded by the pressure sensor, and the ink flow speed Zms is calculated according to the remaining weight of the solid ink;

[0060] Step 4: Compare the preset ink flow threshold value A3 with the ink flow speed Zms to generate a first result and a second result respectively, and then generate different prompts and warnings according to the first result and the second result respectively.

[0061] In this embodiment, the bubble area Nbq in the ink cartridge, the ink cartridge nozzle blockage area Mdm and the air tightness Qmx are collected to reflect the situation inside the ink cartridge. The existence of bubbles will affect the fluidity and printing quality of the ink; nozzle blockage will affect the injection and distribution of the ink, thereby affecting the printing quality and stability; the sealing of the ink cartridge has a direct impact on the volatilization and loss of the ink, as well as the possibility of the ink being contaminated by the outside world. Good air tightness means that the ink in the ink cartridge is not easy to volatilize, and maintains a stable concentration and quality;

[0062] When adding ink, the identification and reminder component is deployed to identify the ink addition degree. When the ink pressure reaches the set threshold, the LED prompt light emits green light to remind the user to fill up the ink to prevent ink overflow and waste. The ink replenishment reminder threshold is adjusted according to the ink usage speed to facilitate user use.

[0063] Example 2

[0064] See also Figure 1 , the bubble area Nbq in the ink cartridge is photographed or observed by an optical imaging device, and the bubble area Nbq in the ink cartridge is identified and quantified by an image processing algorithm, indicating the air bubbles existing in the ink cartridge;

[0065] The nozzle blockage area Mdm indicates the area where the ink cartridge nozzle is partially blocked. The ink cartridge nozzle is photographed or observed using a high-resolution camera, and the blocked area on the nozzle surface is identified and quantified through an image processing algorithm, thereby calculating the nozzle blockage area Mdm.

[0066] Air tightness Qmx monitors the air pressure changes in the ink cartridge through the air pressure sensor. In a closed state, if the air tightness inside the ink cartridge is good, the air pressure should not change significantly; indicating whether the inside of the ink cartridge is completely sealed and no gas leakage or penetration will occur;

[0067] After the bubble area Nbq, the cartridge nozzle blockage area Mdm and the air tightness Qmx are dimensionlessly processed, the cartridge index Mhz is calculated using the following formula:

[0068]

[0069] The preset performance threshold A1 and the cartridge index Mhz are evaluated to generate the following results and solutions:

[0070] If the performance threshold A1> the ink cartridge index Mhz, it means that the current ink cartridge performance is normal and it can be used and refilled after adjustment;

[0071] If the performance threshold A1 ≤ the ink cartridge index Mhz, it means that the current ink cartridge performance is abnormal and cannot be adjusted further. It is necessary to replace a new ink cartridge and then continue to add ink.

[0072] The identification reminder component includes a pressure sensor, a processing chip and an LED prompt light. The pressure sensor and the processing chip are installed inside the ink cartridge, and the LED prompt light is installed on the surface of the ink cartridge. The LED prompt light has three colors, namely red, yellow and green. The reminder threshold of the pressure sensor is set according to the pressure value of the pressure sensor due to the weight of the ink in the saturated state. When ink is added to the ink cartridge, the ink in the ink cartridge continuously applies pressure to the pressure sensor until the reminder threshold is reached. At this time, the pressure sensor sends a signal, which is received and processed by the processing chip, and the LED prompt light turns on green to remind the user that the ink is full.

[0073] The ink applies pressure to the pressure sensor on the surface of the ink cartridge, and then the remaining ink after each printing task is completed is calculated, and the ink usage ΔM after each printing task is completed is obtained through differential calculation. t , ΔM t =M t -M t-1 ;M t represents the first ink change after the tth task, M t-1 represents the second ink change in the t-1th cycle; and according to the ink usage ΔM after each printing task is completed t , construct a time-series ink usage change set; construct the absolute value of each ink usage change, and issue a change instruction when each ink usage exceeds the change threshold A2.

[0074] According to the ink usage ΔM after each printing task is completed t , the first ink change after a printing task is completed is calculated by the following formula The second ink change after the last printing task is completed Represents the ink volume change trend under sequential printing tasks:

[0075]

[0076] And a number of first ink change amounts The second ink change amount of the previous print task Create a time series ink volume change set and make the following records: in, represents the absolute value of the ink volume change after the jth printing task is completed, and They are compared with the change threshold B respectively. If the change threshold A2 is exceeded, it means that the change of each printing ink volume is abnormal, and the first instruction is generated; if the change threshold A2 is not exceeded, it means that the change of each printing ink volume is stable and there is no abnormality.

[0077] The pressure sensor records the remaining amount of ink after each printing task is completed by gradually reducing the ink pressure. When the remaining amount of ink reaches 75% of the total amount, the recording stops and the current ink flow speed Zms starts to be calculated.

[0078] The ink flow speed Zms is calculated by the following formula:

[0079]

[0080] In the formula, Ysj is the average time, which means the average completion time of the printing task per hour, and B is the correction constant;

[0081] By comparing the preset ink flow threshold A3 with the ink flow speed Zms, the following results are generated:

[0082] If the ink flow threshold value A2> the ink flow speed Zms, it means that the current ink flow speed is slow, and the first result is generated;

[0083] If the ink flow threshold value A2 ≤ the ink flow speed Zms, it means that the current ink flow speed is fast, and the second result is generated.

[0084] When the ink flow speed is slow and the first result is generated, the prompt threshold of the ink cartridge remaining amount is adjusted to: the remaining ink pressure weight is 15% of the total ink pressure weight, at which time the LED prompt light turns yellow to remind;

[0085] When the ink flow speed is fast and the second result is generated, the prompt threshold of the ink cartridge remaining amount is adjusted to: the remaining ink pressure weight is 25% of the total ink pressure weight, at which time the LED prompt light turns yellow to remind;

[0086] When there is no ink left in the ink cartridge, the LED indicator will light up red to remind you to refill the ink.

[0087] In this embodiment, the bubble area Nbq reflects the design defects and aging degree of the ink cartridge. A smaller bubble area means less air in the ink cartridge, and the ink in the ink cartridge is of higher quality and purer quality, which helps to improve the printing quality. The nozzle blockage area Mdm reflects the smoothness of the ink cartridge nozzle. The obstruction of ink outflow will lead to incomplete printing patterns, uneven colors or ink leakage, thereby affecting the printing quality. However, a small blockage area or no blockage means that the ink cartridge nozzle is in good condition and the printing quality is more reliable. The airtightness Qmx reflects whether the inside of the ink cartridge prevents gas penetration or ink volatilization. If the airtightness of the ink cartridge is poor, external air will enter the ink cartridge, resulting in ink dilution or contamination, thereby affecting the printing quality.

[0088] Evaluate the ink cartridge performance by using the ink cartridge index Mhz to choose to replace or repair the ink cartridge, which not only improves the printing quality and printing efficiency, reduces the occurrence of waste tasks, but also reduces the waste paper caused by printing failures due to the ink cartridge, thus reducing printing costs;

[0089] In addition, by identifying the reminder component, the ink capacity in the ink cartridge is monitored and reminded in real time through the change of ink pressure; when adding ink, the LED prompt light is used to remind the ink filling degree to prevent ink overflow and waste; when printing, the system calculates the ink flow speed Zms by recording the ink remaining amount, usage and changes after each printing task, and generates an adjustment plan for the corresponding reminder threshold based on the comparison between the preset ink flow threshold A3 and the ink flow speed Zms. Because under the same capacity, if the ink flow speed Zms is fast, it means that the ink usage time is short, and if the ink flow speed Zms is slow, it means that the ink usage time is long, so the reminder threshold is adjusted according to the ink flow speed Zms, and the insufficient ink amount is prompted in advance during the printing process to ensure the stability and continuity of the printing process; the pressure sensor continuously monitors the ink pressure. When the ink is used up, the pressure sensor cannot detect the pressure, and the processing chip sends a signal to the LED prompt light, making the LED prompt light light red to remind the user to add ink; it provides users with a convenient printing experience and maintenance guidance.

[0094] Adjust the module to adjust the threshold value of the yellow LED indicator light according to the ink feeding speed Zms;

[0095] When the pressure sensor cannot identify the ink pressure, it means the ink is used up. At this time, the chip will identify it and send a signal to make the LED indicator light red.

[0096] The processing chip is used to receive analog signals from the pressure sensor, convert them into digital signals using analog signal processing technology, filter, amplify and reduce noise, capture and analyze changes in pressure values, and is also responsible for setting the reminder threshold of the pressure sensor. The processing chip uses a specific signal processing algorithm to analyze the changing pattern of pressure values, including identifying trends in pressure values. Once the processing chip determines the status of the ink, such as full, it controls the output of the LED prompt light and sends a control signal to the LED prompt light through the digital output pin to light up the corresponding color.

[0097] In this embodiment, the recognition and reminder components are used to integrate the recognition, evaluation, adjustment and reminder functions, and the processing power of the processing chip is utilized to achieve comprehensive monitoring and management of the ink cartridge status.

The amount of ink in the ink cartridge is estimated by the pressure value exerted by the ink on the pressure sensor, and then the processing chip sends a signal to the LED prompt light. The LED prompt light emits red, yellow and green lights according to the received signals, so as to remind the user of the three situations of full ink, early ink replenishment and ink exhaustion;
