Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to the method for heating the thermal point according to the temperature interval range and the paper feeding speed, provided by the embodiment of the invention, the corresponding relation table of the temperature interval range, the paper feeding speed and the heating time is inquired, and the corresponding thermal point heating time data is obtained under different real-time temperatures and different paper feeding speeds to heat the thermal point, so that the precision control of the thermal point heating process is realized, and the stability of thermal printing is improved.
As shown in fig. 1, which is a schematic diagram of a method for heating a thermal point according to a temperature range and a paper feeding speed according to an embodiment of the present invention, the method mainly includes the following steps:
step 1, acquiring a corresponding relation table of temperature interval range, paper feeding speed and heating time;
wherein the corresponding relation table comprises a plurality of corresponding relation records; the corresponding relation records comprise temperature data, paper feeding speed data and heating time data corresponding to the temperature data and the paper feeding speed data.
Specifically, the thermal printing device acquires a corresponding relation table of a temperature range, a paper feeding speed and heating time from a local storage medium; the thermal printing apparatus herein includes at least a storage medium for storing data, a paper feed motor for thermal printing paper, a thermal dot for printing thermal printing paper, a thermistor for obtaining real-time temperature data of the thermal dot, and the like.
Here, the thermal printing apparatus may be a thermal printer, or may be a terminal apparatus or a server having a thermal printing function. The structure of the corresponding relation table is shown in a table I, and the corresponding relation table is composed of M (M is an integer larger than 0) corresponding relation records, wherein each corresponding relation record comprises temperature data, paper feeding speed data and heating time data corresponding to the temperature data and the paper feeding speed data; here, the temperature data is a specific temperature interval range; the paper feeding speed data is specific speed data; the heating time data is time data for heating the thermosensitive dot.
Watch 1
And 2, acquiring real-time temperature data of the first thermosensitive point and first real-time paper feeding speed data.
Specifically, the thermal printing device obtains the real-time temperature of the thermal point through the thermistor to generate first thermal point real-time temperature data, and obtains first real-time paper feeding speed data by reading the speed configuration parameters of the paper feeding motor.
Here, the real-time temperature of the thermal point is by default identical to the ambient temperature before the thermal point is not heated.
For example, the thermal printing device is placed outdoors, the outdoor temperature is 11 ℃, the temperature of the thermal point is consistent with the ambient temperature before heating is not started, so that the real-time temperature data of the first thermal point is 11 ℃; and the speed configuration parameter of a paper feeding motor of the thermal printing equipment is 5mm/s, and the first real-time paper feeding speed data is 5 mm/s.
And 3, inquiring the corresponding relation record of the corresponding relation table according to the first real-time temperature data of the thermal sensitive point and the first real-time paper feeding speed data, and extracting corresponding heating time data as thermal sensitive point heating time data when the first real-time temperature data of the thermal sensitive point meets the temperature data and the first real-time paper feeding speed data is equal to the paper feeding speed data.
For example, the real-time temperature data of the first thermosensitive point is 11 ℃, the real-time paper feeding speed data of the first thermosensitive point is 5mm/s, the correspondence table is specifically shown in table two, and M is 10; and inquiring a table II of the thermal printing equipment, recording the 1 st, 2 nd, 3 rd, 4 th and 5 th corresponding relation records according to the corresponding relation that the temperature interval range comprises the first thermal point real-time temperature data (11 ℃), searching the corresponding relation record that the paper feeding speed data is equal to the first real-time paper feeding speed data (5mm/s) from the 1 st, 2 nd, 3 rd, 4 th and 5 th corresponding relation records to obtain the 1 st corresponding relation record, and extracting the 1 st heating time data (24ms) from the 1 st corresponding relation record to obtain the thermal point heating time data of 24 ms.
Watch two
And 4, heating the thermal point according to the thermal point heating time data.
Here, the thermal printing apparatus performs a timed heating process on the thermal dots using a heating current, which is thermal dot heating time data. For example, when the thermal dot heating time data is 24ms, the thermal printing apparatus performs a timed heating process on the thermal dots by using a heating current, and the current heating time is 24 ms.
In addition, the thermal printing device can detect whether the real-time temperature of the thermal point reaches the target temperature data after the thermal point is heated according to the thermal point heating time data every time, can also automatically detect whether the real-time temperature of the thermal point reaches the target temperature data regularly, and can also provide a single triggering mode for detecting whether the real-time temperature of the thermal point reaches the target temperature data by the user selection. Wherein, whether the real-time temperature to the temperature sensing point reaches target temperature data detects, specifically includes:
acquiring target temperature data;
specifically, the thermal printing device acquires preset target temperature data from a storage medium;
here, the target temperature data is a specific target temperature interval range preset by the thermal printing device, when the real-time temperature of the thermal dots is within the target temperature interval range, the gray scale information of the printed pattern can reach a gray scale threshold (i.e. the printing color depth is normal), and the definition information of the printed pattern can reach a definition threshold (i.e. the printing can not generate blocking and pattern shading). For example, the target temperature data is 170 ℃ to 180 ℃;
acquiring real-time temperature data of a second thermosensitive point;
specifically, the thermal printing equipment obtains the real-time temperature of the thermal point through the thermistor to generate second thermal point real-time temperature data;
when the real-time temperature data of the second thermal point is lower than the target temperature data, generating insufficient heating compensation information of the thermal point;
here, there are various reasons for generating insufficient heat compensation information of the thermal point (for example, insufficient heat compensation due to aging of the thermal printing apparatus, insufficient heat compensation due to aging of the thermal point component, etc.), and the generation of insufficient heat compensation information of the thermal point indicates that the heating time given by the correspondence table needs to be adjusted when increasing; for example, the real-time temperature data of the second thermal point is 168 ℃, the thermal printing equipment considers that the thermal point is insufficiently heated and does not reach the target temperature data (170 ℃ to 180 ℃), and then insufficient thermal point heating compensation information is generated to prompt information and further activate a corresponding relation table time-increasing debugging process;
and when the real-time temperature data of the second thermosensitive point is higher than the target temperature data, generating the information that the heating compensation of the thermosensitive point is too large.
There are various reasons for generating the information that the heating compensation of the thermal point is too large (for example, the heating compensation is too large due to too large heating current of the thermal printing device), and the generation of the information that the heating compensation of the thermal point is too large indicates that the heating time given by the correspondence table needs to be adjusted when the heating time needs to be reduced; for example, the real-time temperature data of the second thermal point is 181 ℃, the thermal printing device considers that the thermal point is overheated and exceeds the target temperature data (170 ℃ to 180 ℃), and then information of excessive thermal point heating compensation is generated for information prompt and further activation of the time reduction debugging process of the corresponding relation table.
In summary, when the thermal printing apparatus processes thermal printing, the method for heating thermal dots according to the temperature interval range and the paper feeding speed provided by the embodiment of the invention is introduced, and the corresponding thermal dot heating time data is acquired at different real-time temperatures and different paper feeding speeds by querying a corresponding relation table of the temperature interval range, the paper feeding speed and the heating time to heat the thermal dots, so that the precision control of the thermal dot heating process is realized, and the stability of the thermal printing is improved.
In the second embodiment of the present invention, the corresponding relationship table of the temperature range, the paper feeding speed, and the heating time used in the first embodiment is debugged, and when the corresponding relationship table is first put into use, the corresponding relationship table needs to be debugged (initialized), and when the thermal printing apparatus generates insufficient thermal point heating compensation information or excessive thermal point heating compensation information, the corresponding relationship table also needs to be debugged.
As shown in fig. 2, which is a schematic diagram of a debugging method of a correspondence table of a temperature range, a paper feeding speed and a heating time according to a second embodiment of the present invention, the method mainly includes the following steps:
step 101, acquiring a corresponding relation table of temperature interval range, paper feeding speed and heating time;
wherein the corresponding relation table comprises a plurality of corresponding relation records; the corresponding relation records comprise temperature data, paper feeding speed data and heating time data corresponding to the temperature data and the paper feeding speed data.
Specifically, the thermal printing device acquires a corresponding relation table of a temperature range, a paper feeding speed and heating time from a local storage medium; the thermal printing apparatus herein includes at least a storage medium for storing data, a paper feed motor for thermal printing paper, a thermal dot for printing thermal printing paper, a thermistor for obtaining real-time temperature data of the thermal dot, and the like.
Here, the thermal printing apparatus may be a thermal printer, or may be a terminal apparatus or a server having a thermal printing function. The structure of the corresponding relation table is shown in a table I, and the corresponding relation table is composed of M (M is an integer larger than 0) corresponding relation records, wherein each corresponding relation record comprises temperature data, paper feeding speed data and heating time data corresponding to the temperature data and the paper feeding speed data; here, the temperature data is a specific temperature interval range; the paper feeding speed data is specific speed data; the heating time data is time data for heating the thermosensitive dot.
Step 102, sequentially marking the corresponding relation records in the corresponding relation table as debugging corresponding relation records; and taking the temperature data recorded by the debugging corresponding relation as initial temperature data, and taking the paper feeding speed data recorded by the debugging corresponding relation as debugging paper feeding speed data.
Here, in the second embodiment, the thermal printing apparatus will debug the heating time data in each corresponding relationship record in the corresponding relationship table, and mark the corresponding relationship record as a debugging corresponding relationship record before debugging each corresponding relationship record; the temperature data recorded by the debugging correspondence relation is used as initial temperature data (specifically, a temperature range), and the paper feeding speed data recorded by the debugging correspondence relation is used as debugging paper feeding speed data.
For example, when the thermal printing apparatus debugs the correspondence table, the specific content of the correspondence table is as shown in table two, when the 1 st correspondence record is debugged, the 1 st initial temperature data is in the temperature range of 10 ℃ to 20 ℃, and the 1 st debugged paper feeding speed data is 5 mm/s; when the 2 nd corresponding relation record is debugged, the 2 nd initial temperature data is in the temperature range of 10 ℃ to 20 ℃, and the 2 nd debugging paper feeding speed data is 6.25 mm/s; and analogizing in turn, when the 10 th corresponding relation record is debugged, the 10 th initial temperature data is in the temperature range of 20 ℃ to 30 ℃, and the 10 th debugging paper feeding speed data is 50 mm/s.
Specifically, the thermal printing apparatus acquires preset target temperature data from a storage medium.
Here, the target temperature data is a specific target temperature interval range preset by the thermal printing device, when the real-time temperature of the thermal dots is within the target temperature interval range, the gray level information of the printed pattern can reach a gray level threshold (i.e. the printing color depth is normal), and the definition information of the printed pattern can reach a definition threshold (i.e. the printing can not generate blocking and pattern shading). The target temperature data can be set before the thermal printing equipment leaves the factory, and can be modified after the thermal printing equipment leaves the factory. For example, the target temperature data is 170 ℃ to 180 ℃.
And step 104, heating the thermosensitive point according to the initial temperature data and the target temperature data, heating the real-time temperature of the thermosensitive point from the initial temperature data to the target temperature data, and counting the heating time to obtain the debugging heating time.
For example, the target temperature data is 170 ℃ to 180 ℃, the specific content of the correspondence table is shown in table two, when the thermal printing device debugs the 1 st correspondence record, the thermal point is subjected to timing heating treatment, the real-time temperature of the thermal point is heated from the temperature range of 10 ℃ to 20 ℃ to the temperature range of 170 ℃ to 180 ℃, and the obtained heating time is used as the 1 st debugging heating time; when the thermal printing equipment debugs the 2 nd corresponding relation record, the obtained heating time is used as the 2 nd debugging heating time; by analogy, when the thermal printing apparatus is debugging the 10 th correspondence record, the obtained heating time is taken as the 10 th debugging heating time.
Step 105, obtaining the debugging printing pattern information.
Here, the debug print pattern information is a fixed print pattern information (a figure, a character, or a combination of a character and a figure) which is prepared for the thermal printing apparatus to test the printing effect.
wherein the printing effect information comprises printing gray information and printing definition information.
Here, the print effect information obtained by performing the print effect recognition processing on the print pattern mainly includes two pieces of information: printing gray information and printing definition information; print grey scale information sign printing colour effect (if the heat sensitive point heating is not enough can lead to the colour degree of depth not enough to make and print grey scale information not up to standard), print definition information sign printing definition effect (if the heat sensitive point heating too big can lead to printing the adhesion, the pattern is tinged, thereby makes and prints definition information not up to standard).
For example, the specific content of the correspondence table is as shown in table two, when the thermal printing device debugs the 1 st correspondence record, after heating the thermal point to the target temperature data through the 1 st debugging heating time, the 1 st printing effect information (including the 1 st printing gray information and the 1 st printing definition information) is obtained by performing uniform printing and effect identification on the debugging printing pattern information according to the 1 st debugging paper feeding speed data (5 mm/s); when the thermal printing equipment debugs the 2 nd corresponding relation record, obtaining 2 nd printing effect information (including 2 nd printing gray information and 2 nd printing definition information); by analogy, when the thermal printing apparatus is debugging the 10 th correspondence record, the 10 th printing effect information (including the 10 th printing gradation information and the 10 th printing definition information) is obtained.
Here, the reason why the print gradation information is caused to be smaller than the gradation threshold value is that the temperature of the thermal dots is insufficient; on one hand, under the condition that the target temperature data is not changed, the debugging heating time of the thermal point is gradually increased according to the specified time increasing step, so that the temperature of the heated thermal point is adjusted from the bottom to the top of the interval range of the target temperature data; on the other hand, target temperature data can be directly improved, and debugging heating time is prolonged; after the heating time is increased, the thermal printing device heats the thermal point by using the heating time, and then the step 106 is carried out to continue the printing effect recognition until the recognized printing gray scale information exceeds the gray scale threshold value.
For example, the target temperature data is 170 ℃ to 180 ℃, the specific content of the correspondence table is as shown in table two, when the thermal printing device debugs the 1 st correspondence record, the obtained 1 st debugged heating time is 24ms, the 1 st printed gray scale information obtained by uniformly printing the debugged print pattern information according to the 1 st debugged paper feeding speed data (5mm/s) and identifying the effect is not satisfied with the gray scale threshold value, the thermal printing device performs 1 time increase processing on the 1 st debugged heating time by taking 0.5 ms/time as the time increase step length to obtain the 1 st increased debugged heating time of 24.5ms, the 1 st debugged heating time before the time increase is replaced by the 1 st increased debugged heating time to obtain a new 1 st debugged heating time of 24.5ms, the thermal printing device heats the thermal point from the initial temperature data by taking the new 1 st debugged heating time as the heating time to make the thermal point reach the target temperature data, and then the step 106 is carried out to carry out the printing effect identification until the printing gray information is greater than or equal to the gray threshold value.
108, when the printing definition information is smaller than a definition threshold value, reducing the debugging heating time to obtain reduced debugging heating time; taking the reduced debugging heating time as new debugging heating time, carrying out timing heating treatment on the thermosensitive point according to the new debugging heating time, and heating the real-time temperature of the thermosensitive point from initial temperature data to target temperature data; go to step 106.
Here, the reason why the print definition information is caused to be smaller than the definition threshold is that the temperature of the thermal dots is excessively high; on one hand, under the condition that the target temperature data is not changed, the debugging heating time of the thermal point is gradually reduced according to the specified time reduction step, so that the temperature of the heated thermal point is adjusted from the top to the bottom of the interval range of the target temperature data; on the other hand, target temperature data can be directly reduced, and debugging heating time is shortened; after the heating time is reduced, the thermal printing device heats the thermal point by using the heating time, and then goes to step 106 to continue the print effect recognition until the recognized print definition information exceeds the definition threshold.
For example, the target temperature interval is 170-180 ℃, the specific content of the correspondence table is as shown in table two, when the thermal printing device debugs the 2 nd correspondence record, the obtained 2 nd debugged heating time is 26ms, the 2 nd printing definition information obtained by uniformly printing the debugged printing pattern information according to the 2 nd debugged paper feeding speed data (6.25mm/s) and identifying the effect does not meet the definition threshold value, the thermal printing device uses 0.5 ms/time as the time reduction step length, performs 1 time reduction processing on the 2 nd debugged heating time to obtain the 2 nd reduced debugged heating time of 25.5ms, uses the 2 nd debugged heating time before the time increase to replace the 2 nd debugged heating time to obtain the new 2 nd debugged heating time of 25.5ms, the thermal printing device uses the new 2 nd debugged heating time as the heating time to heat the thermal point from the initial temperature data to the target temperature data, and then, the step 106 is carried out to carry out printing effect identification until the printing definition information is greater than or equal to the definition threshold value.
And step 109, when the printing gray information is greater than or equal to the gray threshold and the printing definition information is greater than or equal to the definition threshold, taking the debugging heating time as the heating time data recorded by the debugging corresponding relationship.
The debug heating time here is the latest debug heating time.
For example, the specific contents of the correspondence table are as shown in table two, and after debugging, the thermal printing apparatus only adjusts the 1 st and 2 nd correspondence records: if the latest 1 st debug heating time is 24.5ms, the latest 2 nd debug heating time is 25.5ms, and the 3 rd to 10 th debug heating times are not changed, the corresponding relationship table after debugging is shown in table three:
watch III
In summary, when the thermal printing effect changes, the thermal printing apparatus employs the method for debugging the correspondence table of the temperature interval range, the paper feeding speed and the heating time provided by the embodiment of the invention, so that the accuracy of the correspondence table can be repaired.
According to the method for heating the thermal point according to the temperature interval range and the paper feeding speed, which is provided by the embodiment of the invention, the precision control of the thermal point heating process is realized and the stability of thermal printing is improved based on the corresponding relation table of the temperature interval range, the paper feeding speed and the heating time.
