In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Fig. 1 is a schematic flow chart of an implementation of a printing method provided in an embodiment of the present application, and as shown in the figure, the method may include the following steps:
Step S101, obtaining the current monitoring time tiFirst printing parameters D in corresponding time windowiWherein the current monitoring time tiThe corresponding time window is the current monitoring time tiIn the previous preset time period, i is more than or equal to 2, and i is a positive integer.
In the embodiment of the present application, a plurality of monitoring times t may be setiFor example, a plurality of monitoring times may be generated in a preset time period T, for example, the 1 st monitoring time T12 nd monitoring time t2… … th monitoring time t of i-1 sti-1I th monitoring time ti. The time difference between adjacent monitoring instants being the time period T, i.e. T2-t1＝T，ti-ti-1＝T。
Each monitoring time corresponds to a time window, which may be monitoring time tiThe first N time periods. As an example, the time window of the 12 th monitoring time may be a time range represented by 6 time periods before the 12 th monitoring time, i.e. a time range between the 6 th monitoring time and the 12 th monitoring time.
Of course, in practical applications, the time period T may be preset, and the number of time periods included in the time window may also be preset, and the above example is only used to illustrate the relationship between the monitoring time and the time window, and does not represent any limitation. At the ith monitoring time t iFirst printing parameters D in corresponding time windowiFor the i-N monitoring time ti-NTo the ith monitoring time tiTotal print parameters in this time frame. By way of example, when the first print parameter is the number of print dots, the ith monitoring time tiFirst printing parameters D in corresponding time windowiFor the i-N monitoring time ti-NTo the ith monitoring time tiTotal beats in this time rangeAnd (7) printing points. When the printing parameter is the number of printing lines, the ith monitoring time tiFirst printing parameters D in corresponding time windowiFor the i-N monitoring time ti-NTo the ith monitoring time tiThe total number of printed lines in this time frame.
Therefore, the first printing parameter DiIndicating the monitoring time tiTotal print parameters within the corresponding time window. The first printing parameter may subsequently also be represented by the total printing parameter. As another embodiment of the present application, the i-N monitoring times t are obtainedi-NTo the ith monitoring time tiFirst printing parameter D in this time rangeiThe i-N monitoring time t can be seti-NTo the ith monitoring time tiAnd accumulating the second printing parameters d in a single time period corresponding to each monitoring moment determined by each monitoring moment in the time range.
By way of example, assume that the monitoring time t iCorresponding current time period TiA second printing parameter of di，TiFor the purpose of monitoring the time t from the lasti-1To the current monitoring time tiTime range of (d). At the i-N monitoring time ti-NTo the ith monitoring time tiFirst printing parameter D in this time rangeiAnd accumulating the second printing parameters in the time period corresponding to each monitoring moment in the time range: di-N+1+……+di＝Di。
Therefore, the second printing parameter diIndicating the slave monitoring time ti-1To monitoring time tiWithin a time range (i.e. a single time period T)i) The individual printing parameters of (1). The second print parameter may also be subsequently represented by a single print parameter.
As described above, since the time window is preset to be N time periods T, the first printing parameters in the time window corresponding to each monitoring time are the accumulation of N second printing parameters from the nth monitoring time, however, it is clear that the first printing parameters D in the time window corresponding to the 1 st monitoring time are the accumulation of N second printing parameters1Only 1 second printing parameter d is added up (d)1) (ii) a First printing parameter D in time window corresponding to 2 nd monitoring moment2Only 2 second printing parameters d are added up (d)1And d2) (ii) a First printing parameter D in time window corresponding to the N-1 th monitoring time N-1Only N-1 d accumulations (d)1、d2… … and dN-1). Although d is to be notediAnd DiAre all printing parameters, however, diRepresenting a single printing parameter within a time period T before the ith monitoring instant, DiThe total print parameters are shown N time periods T before the ith monitoring instant.
Referring to fig. 2, fig. 2 is a relationship among monitoring time, time window and printing parameters provided by the embodiment of the present application, as shown in the figure, to monitor time tiFor example, diFor monitoring the time tiCorresponding time period TiSecond printing parameter of DiFor monitoring the time tiCorresponding time window (N time periods T, or T)i-NTo ti) First printing parameter (d)i-N+1+……+di)。
As another embodiment of the present application, may also be according to Di＝Di-1-di-N+diCalculating the monitoring time tiFirst printing parameters D in corresponding time windowi；
Wherein D isiFor monitoring the time tiFirst printing parameters in corresponding time windows, Di-1For monitoring the time ti-1Obtained first printing parameters, di-NFor monitoring the time ti-1The earliest monitoring time t in the corresponding time windowi-NSecond printing parameter of, ti-N＝ti-NT，diFor monitoring the time tiThe second printing parameter of (1).
In the embodiment of the present application, in addition to the monitoring time tiSumming the second printing parameters monitored at all the monitoring moments in the corresponding time window to obtain a first printing parameter, and utilizing the first printing parameter D calculated last time i-1And (4) obtaining.
First, D is obtained from the drawing shown in FIG. 2i-1，Di-1For monitoring the time ti-N-1To monitoring time ti-1Total number of printed dots in between, Di-1＝di-N+……+di-1As described above, Di＝di-N+1+……+diTherefore, Di＝Di-1-di-N+di。
Step S102, according to the first printing parameter D in the time windowiAnd adjusting the printing speed.
In the embodiment of the present application, as described above, the first printing parameter D within the time windowiThe number of print dots may be used, or the number of print lines may be used. For the convenience of distinction, the total number of printing points in the time window is recorded as Di1Recording the total number of printing lines in the time window as Di2Correspondingly, monitoring the time tiTime period T ofiThe number of individual print points in is noted as di1Monitoring time tiTime period T ofiInner single number of printing lines is recorded as di2。
Can be the total printing point number Di1Setting an upper limit value and a lower limit value of the number of dots, or setting a total printing line number Di2And setting a line number upper limit value and a line number lower limit value.
If the first printing parameter DiContaining only one parameter, e.g. only the total number of printed dots Di1Or only the total number of printing lines Di2According to the first printing parameters D in the time windowiAdjusting the print speed comprises:
when the first printing parameter is smaller than the corresponding lower limit value (meeting a first preset condition) and the printing mode is a low-speed printing mode, adjusting the printing mode to a high-speed printing mode;
And when the first printing parameter is larger than the corresponding upper limit value (the second preset condition is met) and the printing mode is the high-speed printing mode, adjusting the printing mode to be the low-speed printing mode.
If the first printing parameter DiInvolving a plurality of parameters, e.g. including the total number of printed dots Di1And the total number of printing lines Di2According to the first printing parameters D in the time windowiAdjusting the print speed comprises:
the total printing number Di1Less than the lower limit value of dot number and/or the total number of printing lines Di2When the number of lines is less than the lower limit value (first preset condition) and the printing mode is a low-speed printing mode, adjusting the printing mode to a high-speed printing mode;
the total printing number Di1Greater than the upper limit value of dot number and/or the total number of printing lines Di2And when the number of dots is larger than the upper limit value of the number of dots (second preset condition) and the printing mode is the high-speed printing mode, adjusting the printing mode to be the low-speed printing mode.
In practical application, the lower limit value of the number of points may be recorded as a first preset value, the lower limit value of the number of lines may be recorded as a second preset value, the upper limit value of the number of points may be recorded as a third preset value, and the upper limit value of the number of lines may be recorded as a fourth preset value. Correspondingly, the first preset value is smaller than the third preset value, and the second preset value is smaller than the fourth preset value.
According to the printing method provided by the embodiment of the application, monitoring time can be set when printing is carried out, at each monitoring time, the printing parameters of the preset time period before the current monitoring time can be obtained, and the printing speed is adjusted based on the printing parameters of the preset time period before the monitoring time; since each time the printing speed is adjusted, it is determined based on the printing parameters a certain period of time before the monitoring time, and the temperature of the print-related device at the monitoring time is related to the print parameter at a time period prior to the monitoring time, therefore, the subsequent printing speed can be determined by the printing parameters of a certain time period before the monitoring time related to the printing related devices, thereby avoiding the problem of overhigh temperature of the printing related devices caused by pursuing the printing speed, or the problem of preventing the temperature of the printing-related device from being excessively high and the printing speed from being controlled excessively low is avoided, so that the printing speed can be accurately controlled, and, the printing method provided by the embodiment of the application is a method for controlling the printing speed in a software form, does not need to increase hardware, and also avoids the problem of larger error caused by hardware aging. In practical application, the subsequent printing mode is determined by setting the upper limit value and the lower limit value corresponding to the printing parameters and the current printing mode, so that the problem of overhigh temperature of printing related devices caused by overhigh speed during printing is avoided, and the problem of low printing efficiency caused by keeping low-speed printing for limiting the temperature of the printing related devices is also avoided; the printing speed is determined according to the printing parameters (printing load) in a certain time window before, the printing speed can be flexibly adjusted according to the printing load, the printing efficiency is improved, and the overhigh temperature of relevant printing devices is avoided. In general, short-time printing transactions are abundant, and thus, these conventional prints can be performed in a high-speed manner.
Fig. 3 is a schematic flow chart of another implementation of the printing method provided in the embodiment of the present application, which describes how to adjust the printing speed according to the total printing parameters in the time window in terms of data storage. As shown, the method may include the steps of:
step S301, a timed service process is called with a preset time period T.
In the embodiment of the application, a timing service process can be set, and the timing service process is hung in a timing interrupt service program or a timing task of a system. Thus, the timed service process may be invoked at an agreed time period. The timing service process is used for periodically maintaining the element updating process of the ring array.
By way of example, the time period during which the timing service process is invoked is denoted as T.
Step S302, when the timing service process runs, the storage position c of the annular structure array is obtainedi％NValue d of element(s) in (1)i-N，i>N, wherein N is more than or equal to 2 and is a positive integer, the annular structure array is provided with N storage positions, each storage position of the annular structure array stores a second printing parameter d of a time period T, and% represents a modular division operation.
In the embodiment of the present application, a plurality of variables may be set in advance. For example:
A variable C of an annular structure array for recording a second printing parameter, each element of the array being a counting structure unit, and including two elements, for continuously recording and indicating the number of single printing dots and the number of single printing lines (second printing parameter) in an appointed latest time period T, the annular structure array having N storage units (storage locations), and each storage location C being capable of storing two elements: the number of single printing points and the number of single printing lines, correspondingly, the annular structure array variable has N storage positions which are respectively c1、c2、……、cN；
An indication variable i for indicating a current operation element of the ring structure array;
counting variable Di1The system is used for recording the sum of the printing points in all elements of the structure array variable, namely the total printing points (first printing parameters) in the total printing duration;
counting variable Di2The total of the number of paper feeding lines in all the elements of the variable of the structure array, that is, the total number of paper feeding lines (first printing parameter) in the total printing duration is recorded.
When printing is started, first, the element, the indication variable i, and the count variable D in each storage position C of the structure array variable C need to be seti1Counting variable Di2Are all cleared.
As an example, the ring structure array includes a plurality of units, and since each unit stores the second printing parameter in one time period, the storage location of the ring structure array stores the second printing parameters in the plurality of time periods, and assuming that N is 180 units in the ring structure array, the storage location of the ring structure array stores the total printing parameter of 180 time periods, that is, the first printing parameter.
The indication variable i is increased by 1 once each time the timing service process is called, since the ring structure array is stored in the N storage positions in the form of a ring queue, namely, the second printing parameter is stored in the last storage position c of the ring structure arrayNThen, the next time will beTwo printing parameters are stored in the first storage position c of the ring structure array1In (1). Therefore, after the indicator variable i is increased by 1, N needs to be further divided modulo to determine whether the indicator variable indicates an element in the fourth cell of the ring structure array or indicates the fourth storage location of the ring structure array.
Suppose that the ith monitoring time t is currentlyiThen the currently called period T of the service process is timediThe indication variable i indicates the storage location ci％NLast monitoring time ti-1The indicating variable i indicates c(i-1)％N。
Step S303, the last monitoring time ti-1The obtained first printing parameter Di-1Minus di-NObtaining Di"-1And the position c in the ring structure arrayi％NValue d of element(s) in (1)i-NAnd (5) deleting.
In the embodiment of the present application, as shown in fig. 1 and 2, the current monitoring time t is calculatediIs calculated at the current monitoring time t iThe sum of the second printing parameters in the previous N time periods, therefore, the monitoring time t needs to be obtained firsti-1First printing parameter Di-1First printing parameter Di-1I.e. the monitoring time ti-1The sum of the values of all elements in the corresponding array of ring structures, i.e. Di-1＝di-N+……+di-1For the same reason, the first printing parameter DiI.e. the monitoring time tiThe sum of the values of all elements in the corresponding array of ring structures, i.e. Di＝di-N+1+……+diThus, Di＝Di-1-di-N+diI.e. monitoring the time tiWithin a time window ofiAccording to the acquired monitoring time ti-1Within a time window ofi-1Monitoring time ti-NAcquired second printing parameter di-NAnd a monitoring time tiAcquired second printing parameter diThe operation process in the above steps. Is equivalent toIn the fixed time span of the time window, with one time of calling the timing service process, the time window needs to be moved backward for a time period on the time axis, and the first printing parameter of the time window at the current monitoring time subtracts the earliest second printing parameter from the first printing parameter in the time window at the last monitoring time, and adds the newly calculated second printing parameter.
Therefore, it is necessary to acquire the position c last stored in the ring structure array (i-1)％NNext storage location ci％NValue d of element(s) in (1)i-NSo as to subtract this value.
Of course, if the ring structure array is initialized to 0 when the second printing parameter D is filled in the first round of the ring structure array or the first printing parameter D is calculated in the first round, the first printing parameter D in the time window corresponding to the 1 st monitoring time is as described above1Only 1 second printing parameter d is added up (d)1) (ii) a First printing parameter D in time window corresponding to 2 nd monitoring moment2Only 2 second printing parameters d are added up (d)1And d2) (ii) a First printing parameter D in time window corresponding to the N-1 th monitoring timeN-1Only N-1 d accumulations (d)1、d2… … and dN-1). Therefore, the position c in the ring structure array does not exist from the 1 st monitoring time to the Nth monitoring timei％NValue d of element(s) in (1)i-NThe step of deleting, because now the storage location c of the array of ring structuresi％NStored therein is an initialized element value of 0, there is no value of di-N。
By way of example, in the above description of the ring structure array C, C corresponds to N storage locations, and is C respectively1、c2、……、cNAt the Nth monitoring moment, the position c is stored1、c2、……、cNStored therein are the element values: d 1、d2、……、dN(ii) a At the N +1 th monitoring time, the storage position c is stored due to existence1Element d in (1)1Delete, andwill be element dN+1Is stored in a storage location c1Operation of, storing location c1、c2、……、cNThe element values stored in (a) are respectively: dN+1、d2、……、dN. As can be seen from the above description, the storage location of each element in the array is always unchanged, and the new element completes storage by replacing the old element location (i.e., deleting and being overwritten). Of course, since the storage position in the ring structure array provided by the present application is not changed, only with the monitoring time tiExtending and generating new element value di，diAre sequentially stored in N storage positions of the ring structure array according to the sequence, and when the element obtained last time is stored in the storage position cNThen the element obtained at the current time needs to be stored in the storage location c1Thereby implementing ring storage.

In addition, it should be noted that the second printing parameter diIs related to the monitoring time tiCorrespondingly, for example, when N is 3, the time t is monitored 8The corresponding second printing parameter is d8D is required to be8Is stored in a storage location c8％3(c2) However, since last at storage location c2Stored therein as the monitoring time t5Corresponding second printing parameter d5Therefore, it is necessary to acquire the storage location c8％3Value d of element(s) in (1)8-3And c is8％3Element d in (1)5Clearing is 0 to facilitate subsequent d8Is stored in c8％3(c2) I.e. the process is to8Covered off d5For d, for1、d2、d3In other words, the store time covers the initialized 0 in the ring structure array.

As an application scenario of the present application, at the beginning of printing, the low-speed printing mode may be preset, because the elements in the storage location of the structure array variable C, the indication variable i, and the count variable Di1Counting variable Di2If all the printing parameters are zero-cleared, the first printing parameters D in the time window are smaller (corresponding to the accumulation of a plurality of second printing parameters D with the value of 0), so that any one of the first printing parameters can be determined to be smaller than the corresponding lower limit value, and therefore, the high-speed mode can be adjusted until any one of the first printing parameters D in the time window corresponding to the monitoring time is larger than the corresponding upper limit value, and then the low-speed printing mode is adjusted.
As another application scenario of the present application, at the beginning of printing, a high-speed printing mode may be set in advance, because the elements in the storage location of the structure array variable C, the indication variable i, and the count variable Di1Counting variable Di2All zero clearing is carried out, the first printing parameter D in the time window is smaller (equivalent to thatMany second printing parameters D with the value of 0 are accumulated), so that it can be determined that any one of the first printing parameters is smaller than the corresponding lower limit value, and therefore, the printing mode does not need to be adjusted until any one of the first printing parameters D in the time window corresponding to the monitoring time is larger than the corresponding upper limit value, and then the printing mode is adjusted to the low-speed printing mode.
It can be seen from the above two application scenarios that, in fact, no matter whether the low-speed printing mode or the high-speed printing mode is set at the beginning, the embodiment of the present application is not affected, and certainly, in order to obtain the current printing mode in time, a printing mode variable may be set in advance, for example, when the variable is 0, the variable represents the low-speed printing mode, and when the variable is 1, the variable represents the high-speed printing mode, and when the printing mode is switched, the variable is correspondingly switched to a value together.
