According to the control method of the cooling fan, the working state and the printing state information of the image forming device are acquired, and the cooling fan is controlled according to the acquired working state and the printing state information, so that when the image forming device has different working states and different printing state information, different control can be performed on the cooling fan, the rationality of the control of the cooling fan is effectively improved, the working quality and the efficiency of the cooling fan are ensured, the practicability of the control method is reflected, and the popularization and the application of the market are facilitated.
Fig. 2 is a schematic flow chart of controlling a cooling fan according to operating state and printing state information according to an embodiment of the present invention, and it can be seen with reference to fig. 2 on the basis of the above embodiment, in this embodiment, a specific implementation process of controlling the cooling fan according to the operating state and the printing state information is not limited, and a person skilled in the art may set the control according to a specific design requirement, and preferably, the controlling the cooling fan according to the operating state and the printing state information may include:
s21: and judging the type of the working state.
Because the image forming apparatus may include a plurality of operating states, and the control strategy for the cooling fan may be different in different operating states, it is necessary to first determine the operating state of the image forming apparatus; specifically, the working parameters of the image forming apparatus may be obtained first, the obtained working parameters are analyzed and compared with preset standard working parameters in different working states, the standard working parameters matched with the working parameters are found, and the working state corresponding to the standard working parameters is determined as the current working state of the image forming apparatus.
S22: and if the working state is the standby state, controlling the cooling fan to be closed. Or,
when the working state is the standby state, it indicates that the image forming apparatus does not receive the print job, and further the image forming apparatus does not perform the printing operation, and at this time, the image forming apparatus is maintained at a low temperature, and no adverse effect is caused to other internal elements of the image forming apparatus, so that the cooling fan can be controlled to be in the off state.
S23: and if the working state is the printing working state, controlling the cooling fan to start. Or,
when the working state is the printing working state, the image forming device at the moment receives the printing task and can perform corresponding printing operation according to the printing task, at the moment, the working temperature of the image forming device can be increased due to the printing operation of the image forming device, and in order to avoid adverse effects on internal elements of the image forming device, the cooling fan can be controlled to be in an open state, so that the cooling fan can timely reduce the working temperature of the image forming device, the stable reliability of the printing operation of the image forming device is ensured, and the internal elements of the image forming device are protected powerfully.
S24: and if the working state is the printing end state, acquiring the printing state information in a preset time period before the image forming device is in the printing end state.
When the working state is the printing end state, the image forming device at the moment is proved to have completed the printing task; at this time, the operating temperature of the image forming apparatus may gradually decrease with the increase of the time that the image forming apparatus is in the printing end state, and in order to ensure that the operating temperature of the image forming apparatus may quickly and effectively decrease to the preset safe temperature range, the printing state information in the preset time period before the image forming apparatus is in the printing end state may be acquired, where the preset time period is a preset time parameter, and a person skilled in the art may set a specific value of the preset time period according to a specific design requirement, for example: the preset time period may be set to 10min, 15min, or 20min, etc. In addition, the manner of acquiring the print status information may be: acquiring all printing state information formed by an image forming device, and extracting corresponding printing state information from all the printing state information, specifically, generating all the corresponding printing state information during or after the printing operation of the image forming device, and extracting the printing state information in a preset time period before the printing end state from all the printing state information; for example: if the preset time period is 10min, acquiring printing state information of the image forming device within 10min before the printing end state; the preset time period is 15min, and then the printing state information within 15min before the image forming apparatus is in the printing end state is acquired.
S25: and controlling the cooling fan according to the printing state information.
After the printing state information is acquired, the printing state information can be analyzed and judged, and the cooling fan is controlled according to the analysis and judgment result; the printing state information can include the number of printing tasks, and when the number of printing tasks is greater than or equal to a preset task number threshold value, the cooling fan is controlled to be turned off in a delayed mode; and when the number of the printing tasks is less than the task number threshold value, controlling the cooling fan to be immediately closed, and the like.
By analyzing the working state of the image forming device, the cooling fan can be controlled differently when the image forming device is in different working states, the flexibility and the diversity of the control of the cooling fan are effectively improved, and the stability and the reliability of the control method are further improved.
On the basis of the foregoing embodiment, as can be seen with continued reference to fig. 1-2, the printing status information in this embodiment may include a startup duration and/or a printing frequency of the image forming apparatus, and at this time, the controlling the cooling fan according to the printing status information may include the following sub-steps: acquiring the starting time length of the image forming device and/or the printing frequency of the image forming device in a preset time period before the image forming device is in the printing end state; and controlling the cooling fan according to the starting time and/or the printing frequency. Specifically, the closing time of the cooling fan can be controlled to be different according to different starting time lengths and/or different printing frequencies.
As can be seen with reference to fig. 3-4, when the printing status information may include only the startup duration of the image forming apparatus, the controlling the cooling fan according to the printing status information may include:
s251: the method includes acquiring a startup time length of the image forming apparatus.
The power-on duration is the time duration after the image forming apparatus is powered on, and at this time, the power-on duration may include: the sum of the time when the image forming apparatus is in the standby state, the time when the image forming apparatus is in the print job state, and the time when the image forming apparatus is in the print end state; the starting-up time length can be acquired through the timer, wherein the timer can be installed on the image forming device.
S252: and controlling the cooling fan according to the starting time.
After the startup duration is obtained, the startup duration can be analyzed and processed, and the cooling fan is controlled according to the analysis processing result, so that the cooling fan can be controlled to be closed at different moments according to different startup durations; specifically, controlling the cooling fan according to the startup duration may include:
s2521: and judging the size of the starting-up time length and a preset starting-up time length threshold value.
The startup duration threshold is preset, and a person skilled in the art can set a specific value of the startup duration threshold according to specific design requirements, for example, the startup duration threshold can be set to 20min, 30min or 40min, and the like; after the boot-up duration is obtained, the boot-up duration may be compared to a boot-up duration threshold.
S2522: and if the starting-up time is less than or equal to the preset starting-up time threshold, controlling the cooling fan to be immediately closed after the image forming device is in the printing ending state. Or,
when the analysis and comparison result shows that the starting time is less than or equal to the starting time threshold, the starting time of the image forming device is shorter, and the working temperature of the image forming device is not too high relatively.
S2523: and if the starting-up time length is greater than the starting-up time length threshold value, acquiring the number of printing tasks in a preset time period before the image forming device is in the printing ending state.
When the result of the analysis and comparison indicates that the startup duration is greater than the startup duration threshold, it indicates that the startup duration of the image forming apparatus is longer, and in order to ensure that the working temperature inside the image forming apparatus is not too high, the number of print jobs in a preset time period before the image forming apparatus is in the print end state may be obtained, where the number of print jobs is the total number of print jobs processed and completed by the image forming apparatus in the preset time period before the image forming apparatus is in the print end state by the user, it should be noted that the preset time period in this step is the same as the preset time period in step S24, and both are time parameters preset by the user, and the above statements may be specifically referred to, and are not repeated herein.
In addition, the manner of acquiring the number of print jobs may be: extracting all the print job numbers formed by a preset image forming device, specifically, generating all the corresponding print job numbers after the image forming device performs a printing operation process, and extracting the print state information in a preset time period before the printing end state from all the print state information; for example: if the preset time period is 10min, acquiring the number of printing tasks within 10min before the image forming device is in the printing end state; the preset time period is 15min, then the number of print jobs within 15min before the image forming apparatus is in the print end state is acquired. For example: the print job processed by the image forming apparatus includes: the number of the printing tasks sent by the user A is 2, the number of the printing paper sheets is 5 and 10 respectively, and the printing time is 30min before the printing end state; the number of the printing tasks sent by the user B is 3, the number of the printing paper is 3, 4 and 7 respectively, and the printing time is 10min before the printing end state; the number of print jobs sent by the user c is 1, the number of print sheets is 6, and the printing time is 16min before the printing end state, so that the total number of print jobs processed by the image forming apparatus is the sum of the number of print jobs of the user b and the number of print jobs of the user c within 20min before the image forming apparatus is in the printing end state, which is 4.
Also, in actual operation, there may be a case where the image forming apparatus receives a plurality of print jobs at the same time and does not complete all the print jobs within a preset time period, where the number of print jobs is based on the print jobs that the image forming apparatus has processed within a specified time period, rather than the number of received print jobs. For example: the printer receives 20 copies of the job at the same time, but the job can be processed one by one during printing, each job takes 2 minutes to complete the printing, and at this time, the number of tasks within 20Min is counted, and the obtained result is 10 processed copies.
In addition, when the image forming apparatus performs a printing operation, if two different jobs are transmitted by different users at the same time, the image forming apparatus may seamlessly connect the two jobs in chronological order, and in this case, the image forming apparatus may determine that the two different jobs are one job, for example: 15Min, A sends a 10-page print job and B also sends a 3-page print job, so the printer may receive the two jobs at the same time, but the printing will not stop, and the two jobs will be seamlessly connected together, and at this time, the 2 jobs can be calculated as 1 job.
S2524: and controlling the closing time of the cooling fan to be different according to the number of the printing tasks.
After the number of print tasks is obtained, the number of print tasks can be analyzed and processed, and the cooling fan can be effectively controlled according to the analysis and processing result, specifically, the control of the cooling fan can include controlling the cooling fan to be turned off at different times; referring to fig. 4, the timing for controlling the cooling fan to be turned off according to the number of print jobs may include:
s25241: and judging the size of the number of the printing tasks, a preset first printing number threshold value and a preset second printing number threshold value.
The first print number threshold and the second print number threshold are preset, and a person skilled in the art can set specific values thereof according to specific design requirements, and it should be noted that the second print number threshold is greater than the first print number threshold, for example: the first print number threshold value is 10, and the second print number threshold value is 15; alternatively, the first print number threshold is 10, the second print number threshold is 20, and so on; and analyzing and comparing the acquired number of printing tasks with a first printing number threshold value and a second printing number threshold value respectively.
S25242: and if the number of the printing tasks is smaller than a preset first printing number threshold value, controlling the cooling fan to be turned off in a first time delay after the image forming device is in the printing finishing state. Or,
when the analysis and comparison result indicates that the number of print jobs is smaller than the preset first print number threshold, it indicates that the number of print jobs received by the image forming apparatus is smaller, and further, the number of print operations performed is smaller, and at this time, in order to ensure that the working temperature inside the image forming apparatus is not too high, the cooling fan may be controlled to be turned off with a first time delay, where the first time duration is preset, and a skilled person may determine a specific value of the first time duration according to a specific design requirement, for example, the first time duration may be set to 5s, 10s, or 15s, and so on, as long as it is ensured that the working temperature inside the image forming apparatus is not too high, which is not described herein again.
S25243: and if the number of the printing tasks is greater than or equal to the first printing number threshold and less than a preset second printing number threshold, controlling the cooling fan to be closed in a delayed manner by a second time length after the image forming device is in the printing finishing state. Or,
when the analysis and comparison result shows that the number of print jobs is greater than or equal to the first print number threshold and less than the preset second print number threshold, it indicates that the number of print jobs received by the image forming apparatus at this time is greater and the number of print operations performed is also greater, at this time, in order to ensure that the working temperature inside the image forming apparatus is not too high, the cooling fan may be controlled to be turned off with a delay of a second duration, where the second duration is preset and is greater than the first duration, and a person skilled in the art may determine a specific value of the second duration according to specific design requirements, for example, the second duration may be set to 10s, 15s, or 20s, and the first duration may be 5s, 10s, or 15s, and the like, as long as it is ensured that the working temperature inside the image forming apparatus is not too high, and will not be described in detail herein.
S25244: and if the number of the printing tasks is greater than or equal to the second printing number threshold value, controlling the cooling fan to be closed in a delayed mode for a third time length after the image forming device is in the printing ending state.
When the result of the analysis and comparison indicates that the number of print jobs is greater than or equal to the second print number threshold, it indicates that the number of print jobs received by the image forming apparatus is too large at this time, and further, the printing operation is also too large at this time, in order to ensure that the working temperature inside the image forming apparatus is not too high, the cooling fan may be controlled to be turned off with a delay of a third duration, where the third duration is preset and is greater than the second duration, and a person skilled in the art may determine a specific value of the third duration according to a specific design requirement, for example, the third duration may be set to 20s, 25s, or 30s, and the like, and at this time, the second duration may be 10s, 15s, or 20s, and the like, as long as it is ensured that the working temperature inside the image forming apparatus is not too high, which is not described herein again.
According to the embodiment, the startup time of the image forming device is obtained, the startup time is analyzed and judged, different control can be performed on the cooling fan according to different analysis results, on the basis that the working stability and reliability of the image forming device can be guaranteed, the reasonability of the cooling fan control is effectively improved, and the practicability of the control method is further improved.
It should be noted that fig. 4 is only a preferred technical solution for "controlling the closing time of the cooling fan to be different according to different on-time periods", and any two control solutions of S25242, S25243, and S25244 may be selected to be combined and executed, and "first" and "second" are selectively retained according to a combination relationship.
Fig. 5 is a second flowchart illustrating a process of controlling a cooling fan according to print status information according to an embodiment of the present invention; further, on the basis of the foregoing embodiment, as can be seen with continued reference to fig. 5, the printing status information in the present embodiment may also include only the printing frequency of the image forming apparatus, and in this case, the controlling the heat dissipation fan according to the printing status information may include:
s253: a printing frequency within a preset time period before the image forming apparatus is in a printing end state is acquired.
The specific meaning of the preset time period in this step is the same as that of the preset time period in the step S24, and the above statements may be specifically referred to, and are not repeated herein; in addition, the above-mentioned printing frequency is the number of printing jobs for performing the printing operation in a unit time when the image forming apparatus performs the printing operation in a preset time period, and in this case, the manner of acquiring the printing frequency may include: acquiring the total number of printing tasks in a preset time period, and then taking the ratio of the total number of printing tasks to the preset time period as the printing frequency; or, directly acquiring the printing frequency within a preset time period before the image forming device is in the printing end state through a preset printing frequency acquisition device, wherein the printing frequency acquisition device can be installed on the image forming device; of course, those skilled in the art may also use other methods to acquire the printing frequency, as long as the accuracy and reliability of the acquisition of the printing frequency can be ensured, which is not described herein again.
S254: and controlling the heat radiation fan according to the printing frequency.
After the print frequency is obtained, the print frequency may be analyzed, and the cooling fan is controlled according to an analysis result, specifically, the controlling the cooling fan according to the print frequency may include:
s2541: and judging the printing frequency and the preset first printing frequency threshold value and the second printing frequency threshold value.
The first printing frequency threshold and the second printing frequency threshold are preset, and those skilled in the art can set their specific values according to specific design requirements, and it should be noted that the second printing frequency threshold is greater than the first printing frequency threshold, for example: the first printing frequency threshold value is 5/20 min, and the second printing frequency threshold value is 10/20 min; alternatively, the first printing frequency threshold is 10/20 min, the second printing frequency threshold is 20/20 min, and so on; and analyzing and comparing the acquired printing frequency with a first printing frequency threshold value and a second printing frequency threshold value respectively.
S2542: and if the printing frequency is less than a preset first printing frequency threshold value, controlling the cooling fan to be turned off with a fourth time delay after the image forming device is in the printing end state. Or,
when the result of the analysis and comparison indicates that the printing frequency is less than the preset first printing frequency threshold, it indicates that the number of print jobs received by the image forming apparatus at this time is small, and further the printing frequency of the printing operation is also small, at this time, in order to ensure that the working temperature inside the image forming apparatus is not too high, the cooling fan may be controlled to be turned off with a fourth time delay, where the fourth time is preset, and a person skilled in the art may determine a specific value of the fourth time according to a specific design requirement, for example, the fourth time may be set to 5s, 8s, 10s, or 15s, and so on, as long as it is ensured that the working temperature inside the image forming apparatus is not too high, and details are not described herein.
