Detailed Description
As shown in fig. 1, a general lottery ticket reader mark printing method includes the following steps:
s1, starting printing;
s2, putting down the thermal printing head;
s3, sending data to be printed to a printing head;

s5, starting a thermal printing head to heat;
s6, judging whether the heating time is up;
s7, if yes, judging whether printing is finished;
s8, if yes, printing is finished; if not, return to step S3.
As shown in fig. 1, in the general method for printing a label on a lottery ticket reader, after printing a line of data, the next line of printed data is loaded for printing, and when each line of data needs to be printed, the thermal print head is started to start heating, and after the time required for heating is reached, whether all printing is finished needs to be further determined, if not, the next line of data to be printed is continuously sent to the thermal print head, and then the thermal print head is started to heat, so as to start printing; if all printing is finished, stopping heating the thermal heating head continuously, and finishing printing; the method has the advantages of low printing speed and low working efficiency. The conventional lottery printing technology does not have an intelligent control heating technology, namely a time detection processing method and a cyclic detection heating method based on embedding in a kernel process are not applied to the lottery printing technology, so that the printing efficiency is low, the heating of the thermal printing head cannot be effectively controlled or immediately stopped, the accidental damage of the printing head cannot be avoided, and the service life of the printing head is prolonged.
The embodiment of the invention is just an improvement of the prior lottery printing method, and sends the next line of data to be printed to the printing head while printing one line of data, thereby realizing rapid and continuous printing, namely after printing one line of data, if detecting that the printing is not overtime or unfinished, the next line of data to be printed can be rapidly printed, and the next line of data to be printed is sent while printing; meanwhile, the method for accelerating the printing speed is combined with the intelligent heat control technology, so that the accidental damage of the printing head can be avoided, and the service life of the printing head is prolonged.
As shown in fig. 2, the present embodiment provides a lottery printing method, which specifically includes the following steps:
q1. calculating a first time, the first time being a time required to print a single line of lottery data;
calculating second time according to the first time, wherein the second time is the total time required for printing the lottery data to be printed;
q3. specifying any one of the lottery ticket data to be printed as first target data;
setting to transmit second target data while printing the first target data, wherein the second target data is data next to the first target data;
q5., printing is set to be carried out line by line from the first line of the lottery data to be printed, and the next line of lottery data is automatically printed after one line of lottery data is printed;
detecting whether the printing is overtime;
when the printing timeout of a single line is detected, the printing of the lottery data of the current line is stopped, and the lottery data of the next line is started to be printed;
q8. when a total time elapsed from the start of printing to the current printing is detected, printing is ended.
As a preferred implementation of this lottery ticket printing method, the first time in step Q1 is calculated by using the following formula:
in the formula, E0Printing energy for the heating body; i is0Is the current of the heating body; t is tsVH is the print voltage for the strobe width; vcomIs common electrode voltage drop;
is the resistance value of the heating element; ricIs the internal resistance of the heat-generating IC.
As a preferred implementation of this lottery ticket printing method, the step Q2, that is, the step of calculating the second time according to the first time, specifically includes:
acquiring the first time;
calculating the line number of the data to be printed;
q203, multiplying the first time by the line number of the data to be printed to obtain a third time;
and Q204, amplifying the third time in proportion to obtain the second time.
As a preferred implementation manner of this lottery ticket printing method, the step Q6, that is, the step of detecting whether printing is timed out, specifically includes:
obtaining the first time and the second time;
acquiring the actual consumed time for printing the single-line lottery ticket data as fourth time;
acquiring the total time consumed from the beginning of printing to the current printing as a fifth time;
comparing the magnitudes of the first time and the fourth time;
if the fourth time is less than the first time, judging that the single-line printing is not overtime, and if the fourth time is greater than the first time, judging that the single-line printing is overtime;
comparing the second time with the fifth time;
and Q607. if the fifth time is less than the second time, determining that the total time consumed from the beginning of printing to the current printing is not overtime, and if the fifth time is greater than the second time, determining that the total time consumed from the beginning of printing to the current printing is overtime.
In this embodiment, the first time is a theoretical value of calculated time required for printing single-line lottery data, the second time is a theoretical value of calculated total time required for printing lottery data to be printed, and the third time is to obtain a middle theoretical value of the second time. In step Q204, the third time is scaled up to obtain the second time, where the scaling up is generally small, that is, the third time is scaled up a little to obtain the second time, that is, the total time required for printing the lottery data to be printed. The reason why the third time needs to be properly enlarged is that intermittent delay printing exists due to hardware problems in the printing process, and according to the printing specificity of the lottery ticket, although the time difference required for printing each line of data is very small, a slight gap still exists, in order to ensure that the lottery ticket printer runs normally as far as possible, the printing is directly finished before all the printing is finished. The second time is set to play a role in protecting the thermal printing head while not affecting normal printing as much as possible. The fourth time is an actual value of time actually consumed for printing the single-line lottery ticket data counted by the timer, and the fifth time is an actual value of total time consumed from the beginning of printing to the current printing counted by the timer.
Judgment of whether single-line data printing is overtime:
in this embodiment, the actual time value obtained by timing is compared with the theoretical time value obtained by calculation, that is, the first time (the theoretical time value required for printing single-line lottery data) and the fourth time (the actual time value actually consumed for printing single-line lottery data) are compared, whether the printing time of the single-line lottery data is overtime is determined, when the fourth time (the actual time value actually consumed for printing single-line lottery data) is greater than the first time (the theoretical time value required for printing single-line lottery data), it is determined that the printing time of the single-line lottery data is overtime, the printing of the current-line lottery data is terminated, and the next-line lottery data is started to be printed; and when the fourth time (the actual value of the time actually consumed for printing the single-line lottery data) is less than the first time (the theoretical value of the time required for printing the single-line lottery data), determining that the printing time of the single-line lottery data is not over time, and continuing to print the current-line lottery data. For example, the theoretical value of the time required for printing the first row of lottery data is 500us, when the actual value of the time actually consumed for printing the single row of lottery data displayed on the single-row timer is greater than 500us, such as 501us displayed on the single-row timer, the printer immediately stops printing the first row of lottery data, starts printing the second row of lottery data, recalculates the theoretical value of the time required for printing the second row of lottery data, and the single-row timer also recalculates the actual value of the time actually consumed for printing the second row of lottery data; when the single-line timer displays less than 500us, such as displaying 499us on the single-line timer, if the first line of data is not completely printed, the printer does not finish printing the first line of data, and continues to print the first line of data, and if the first line of data is completely printed when the single-line timer displays 499us, the printer automatically starts the second line of data to start printing; when the time displayed by the single-line timer is just equal to the calculated theoretical value of the printing time of the single-line data, namely just 500us is displayed on the single-line timer, firstly, whether the printing of the first line of data is completely finished at the moment is judged, if the printing of the first line of data is completely finished, the printing of the first line of data is immediately finished, the next line of data is started to be printed, and if the printing of the first line of data is not completely finished, the printing of the first line of data is immediately finished at the next moment, namely 501us, and the next line of data is started to be printed. That is, only when the printing time of the lottery ticket data of one line is detected to be overtime, the printing of the current line of data is stopped, and the printing of the next line of data is started, otherwise, the printing is continued until the printing of the current line is finished, and the printing of the next line of data is started.
Judging whether all the data to be printed are printed overtime:
in this embodiment, whether all the data to be printed is overtime is judged by comparing the second time (the theoretical value of the total time required for printing the lottery data to be printed) with the fifth time (the actual value of the total time consumed from the beginning of printing to the current printing), and when the fifth time (the actual value of the total time consumed from the beginning of printing to the current printing) is greater than the second time (the theoretical value of the total time required for printing the lottery data to be printed), the printing is immediately finished when all the data to be printed is determined to be overtime; and when the fifth time (the actual value of the total time consumed from the beginning of printing to the current printing) is less than the second time (the theoretical value of the total time required for printing the lottery data to be printed), determining that all the data to be printed are not printed overtime, and continuing the printing. For example, the calculated total theoretical time value required for printing the lottery data to be printed at this time is 10s, and when the actual value of the total time consumed from the beginning of printing to the current printing, which is displayed on the total time timer, is greater than 10s, for example, 10s 0ms 1us is displayed on the total time timer, the thermal printing head is immediately stopped from heating, and the printing at this time is finished; when the actual value of the total time consumed from the beginning of printing to the current printing, which is displayed on the total time timer, is less than 10s, for example, 9s is displayed on the total time timer, if the printing is not completely printed, the printing is continued according to the setting, and if the printing is completely printed when 9s is displayed on the total time timer, the heating of the thermal printing head is immediately stopped, and the printing is automatically finished; when the actual value of the total time consumed from the beginning of printing to the current printing displayed on the total time timer is equal to 10s, namely when 10s is just displayed on the total time timer, firstly judging whether the printing is completely finished at the moment, if the printing is completely finished, immediately stopping heating of the thermal printing head, finishing the printing, and if the printing is not completely finished, immediately stopping heating of the thermal printing head at the next moment and finishing the printing. That is, only when the total time consumed from the beginning of printing to the current printing is detected to be overtime, the printing is ended, otherwise, the printing is continued according to the setting until all the printing is finished, and the printing is automatically ended.
In this embodiment, the printing rule is set to send the next line of data to the thermal print head while printing the current line of data, that is, send the second line of data to the thermal print head to wait for printing while printing the first line of data, send the third line of data to the thermal print head to wait for printing while printing the second line of data, send the fourth line of data to the thermal print head while printing the third line of data, and so on. Meanwhile, when the printing is normal, the printing of the next line of data is automatically started every time the printing of one line of data is finished, namely, the printing of the second line of data is automatically started when the printing of the first line of data is finished, the printing of the third line of data is automatically started when the printing of the second line of data is finished, and the printing is finished until all the data of all the lines are completely printed. The printing method is combined with the intelligent heat control technology, namely when each line of data is not printed, the next line of data needs to be sent, then the thermal printing head is started to start heating, the printing is carried out, the printing is stopped when the heating time is up, then whether all the printing is finished is judged, if so, the printing is finished, otherwise, the next line of data to be printed is continuously sent to the thermal printing head for printing; when one line of data is printed, the next line of data to be printed is sent to the thermal printing head to be printed, the time required for printing single line of data and the total time required for printing all data are set, when one line of data and all data are printed without time-out (printing is normal), the thermal printing head is in a continuous heating state, a state that heating is stopped when the next line of data is sent does not exist, namely, printing is continuously carried out, and heating of the thermal printing head is stopped until all data are printed; when the printing of single line of data is overtime, the printing of the current line of data can be stopped, the next line of data is started to start printing, and when all the printing is overtime, the heating of the thermal printing head can be immediately stopped, so that the printing is finished.
Referring to fig. 3, an actual operation flowchart of the printing method according to this embodiment is shown, in which the lottery data printing and the determining whether the single data printing and the all data printing are overtime are executed in parallel, and there is no sequential order, that is, the lottery printer executes printing while performing determining, and then continues to execute printing and continue determining according to the result of the determining.
