It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0023] Unless otherwise specified, the term "a plurality of" means two or more.

[0024] The term "and / or" is a description of the association relationship of the objects, which means that there can be three relationships. For example, A and / or B means that there are three relationships of A or B, or A and B.

[0025] The term "corresponding" can refer to an association relationship or a binding relationship. A and B correspond to each other means that there is an association relationship or a binding relationship between A and B.

[0026] The embodiments of the present disclosure provide a printing device, comprising: a printing body and a detection element. The printing body comprises a screen for display and a paper feeding part for feeding printing paper. The paper feeding part can be a roller type, a paper winding wheel type, or the like. The detection element is arranged on the printing body to detect the printing parameters. Optionally, the detection element is a radar or a distance sensor. A plurality of detection points are arranged on the paper feeding part. The detection element is arranged above or below the paper feeding part to detect the vertical height of the detection element and each detection point, so as to detect whether the heights of different positions of the paper feeding part are consistent. Optionally, the detection element is a radar or a distance sensor for detecting the height of the printing paper at the paper feeding port of the printing device. First, the first vertical height between the detection element and the lowest position of the paper feeding port is recorded when there is no printing paper at the paper feeding port. In the case that there is printing paper at the paper feeding port, the second vertical height between the detection element and the uppermost printing paper is recorded. The difference between the first vertical height and the second vertical height is the height of the printing paper. Optionally, the detection element is a humidity detection element for detecting the humidity of the environment in which the printing device is located and the water content of the printing paper.

[0027] The embodiments of the present disclosure provide a method for determining a jam risk, comprising:

[0028] S101, in the case where the printing device does not execute a printing task, a detection element detects a printing parameter.

[0029] S102, a processor determines a paper jam risk of the printing device according to the printing parameter.

[0030] The printing device not executing a printing task can be that the printing device has not received a printing task, or that the printing device has received a printing task but has not started printing. In the case where the printing device does not execute a printing task, the detection element detects a printing parameter. The printing parameter includes one or more of a height difference between each detection point of a paper feeding part, a printing paper height, a printing environment humidity, and a printing paper water content. For different printing parameters, different detection elements are used for detection, which can be specifically referred to the foregoing. According to the detected printing parameter, it is determined whether the printing device has a paper jam risk.

[0031] In the embodiments of the present disclosure, in the case where the printing device does not execute a printing task, a printing parameter is detected, so as to determine whether the printing device has a paper jam risk. In this way, it can be known whether the printing device has a paper jam risk before printing, so as to maintain the printing device in time. Thus, it is avoided that a paper jam is found in the process of printing, so as to improve printing efficiency. Meanwhile, paper waste can also be avoided.

[0032] Optionally, S102, the processor determines the paper jam risk of the printing device according to the printing parameter, including:

[0033] In the case where any of the printing parameters is greater than a corresponding preset threshold, the processor determines that the printing device has a paper jam risk.

[0034] In the case where all of the printing parameters are less than or equal to respective corresponding preset thresholds, the processor determines that the printing device does not have a paper jam risk.

[0035] As described above, the printing parameter can be one or multiple. When the height difference between the detection points of the paper feeding part (roller or paper feeding wheel) is greater than the first preset threshold, it means that the paper feeding part is worn and is likely to cause paper jam. When the printing paper height is greater than the second preset threshold, it means that the printing paper is too much and exceeds the standard of the printing device, which is also likely to cause paper jam. When the printing environment humidity is greater than the third preset threshold, it means that the printing environment is too humid. In a humid environment, the printing paper is likely to become humid, which is also likely to cause paper jam. When the printing paper water content is greater than the fourth preset threshold, it means that the printing paper is too humid, which is also likely to cause paper jam. In the case of one printing parameter, if the printing parameter is greater than the corresponding preset threshold, it is determined that the printing device has a risk of paper jam; if the printing parameter is less than or equal to the corresponding preset threshold, it is determined that the printing device does not have a risk of paper jam. In the case of multiple printing parameters, if any one parameter is greater than the corresponding preset threshold, it is determined that the printing device has a risk of paper jam; if all the printing parameters are less than or equal to the corresponding preset threshold, it is determined that the printing device does not have a risk of paper jam. In this way, as long as any one parameter is greater than the corresponding preset threshold, it is determined that the printing device has a risk of paper jam, which can timely avoid the occurrence of paper jam.

[0036] Optionally, in S101, the detection element detects the printing parameter, including:

[0037] The detection element obtains the humidity of the environment where the printing device is located.

[0038] In the case that the humidity of the environment is greater than the humidity threshold, the detection element detects the water content of the printing paper.

[0039] Generally, the printing paper is the same as the environment where the printing device is stored. Therefore, if the humidity of the environment where the printing device is located is too large, the water content of the printing paper will also be too large. For example, in the south plum rain weather, the environment humidity is too large, and the printing paper is also easy to become humid. In this case, the humidity of the environment where the printing device is located can reflect the risk of paper jam. Therefore, when the humidity of the environment is greater than the humidity threshold (the third preset threshold in the foregoing), it is determined that the printing device has a risk of paper jam. Otherwise, it does not have a risk of paper jam.

[0040] However, if the printing paper is moved from a dry environment to a humid environment, or the printing paper has a low water absorption, the humidity of the environment where the printing device is located cannot truly reflect the risk of paper jam. Therefore, when the printing parameter includes the humidity of the printing environment, the humidity of the environment where the printing device is located is first detected. When the humidity of the environment is greater than a humidity threshold (the third preset threshold in the foregoing), the water content of the printing paper is further detected. If the water content of the printing paper is greater than a fourth preset threshold, it is determined that the printing device has a paper jam risk. Otherwise, if the water content of the printing paper is less than or equal to the fourth preset threshold, it is determined that the printing device does not have a paper jam risk. Of course, the humidity of the environment can not be detected, and only the water content of the printing paper is detected. In this way, the accuracy of the determination of the paper jam risk of the printing device is ensured through the double detection of the humidity of the environment and the water content of the printing paper.

[0041] Optionally, in combination with Figure 2 As shown in the figure, the detection element detects the printing parameter, including:

[0042] S201, the processor acquires the number of printing papers of the printing device within a preset time period.

[0043] S202, the processor determines a period of detecting the height difference between each detection point of the paper feeding part of the printing device according to the number of printing papers.

[0044] S203, the detection element detects the height difference between each detection point of the paper feeding part of the printing device according to the determined period.

[0045] The wear of the paper feeding part is accumulated over time. If the detection element always detects, it will consume more power. Therefore, the detection period can be set. Alternatively, the number of printed papers of the printing device in a preset time period is obtained. The preset time period can be 7 days, 10 days, or 15 days, etc. According to the number of printed papers, the period of detecting the printing parameter is determined. The more the number of printed papers, the more the wear of the printing device, and the shorter the set detection period. The detection element detects the height difference between each detection point of the paper feeding part according to the determined period. Alternatively, the default detection period is 15 days when the printing device is shipped. When the user uses the printing device, the processor adjusts the detection period according to the above control logic. For example, the average number of printed pages per day in a period of time is N. If N > 800 pages, it means that the printing frequency is high, and it is determined to be detected once a day; if 300 pages < N ≤ 800 pages, it is determined to be detected once every 3 days; if 100 pages < N ≤ 300 pages, it is determined to be detected once a week; if 30 pages < N ≤ 100 pages, it is determined to be detected once every half month; and if N < 30 pages, it is determined to be detected once a month. In addition, the user can also set the detection period by the terminal device according to the actual situation. The terminal device refers to an electronic device with wireless connection function. The terminal device can be connected to the smart home appliance device through the Internet, or can be directly connected to the smart home appliance device through Bluetooth, Wi-Fi, etc. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a built-in vehicle device of a hovercar, or any combination thereof. The mobile device can include, for example, a mobile phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, or any combination thereof, wherein the wearable device includes, for example, a smart watch, a smart bracelet, a pedometer, etc. In this way, the detection period is determined based on the number of printed papers of the printing device in a period of time, which can effectively judge the risk of paper jam while saving a certain amount of power.

[0046] Alternatively, for printing parameters such as printing paper height, printing environment humidity, and printing paper water content, which are not affected by the length of time, the detection period can not be set, and real-time detection can be performed.

[0047] Alternatively, in combination with Figure 3 The embodiment of the present disclosure provides another method for determining the risk of paper jam, which comprises:

[0048] S301, in the case that the printing device does not execute a printing task, the detection element detects the printing parameter.

[0049] S302, the processor determines the risk of paper jam of the printing device according to the printing parameter.

[0050] S303, in the case of determining that the printing device has a paper jam risk, the processor sends the paper jam risk information of the printing device.

[0051] In the case of determining that the printing device has a paper jam risk, the paper jam risk is sent to the relevant personnel. So that the relevant personnel eliminate the risk, thereby ensuring the normal work of the printing device. In the process of sending the paper jam risk information, the relevant content is displayed on the screen. It should be noted that the specific implementation process of steps S301 and S302 can refer to the above-mentioned embodiments, which will not be repeated here.

[0052] Optionally, in combination with Figure 4 As shown in the figure, the processor sends the paper jam risk information of the printing device, including:

[0053] S401, the processor determines the paper jam reason.

[0054] S402, the processor determines the target object of the paper jam risk information prompt according to the paper jam reason.

[0055] S403, the processor sends the paper jam risk information of the printing device to the target object.

[0056] According to the detected printing parameter, the paper jam reason is determined. In the case that the height difference between each detection point of the paper feeding part is greater than the first preset threshold, it is determined that the paper jam reason is the wear of the paper feeding part. In the case that the printing paper height is greater than the second preset threshold, it is determined that the paper jam reason is that the paper quantity exceeds the placement standard. In the case that the humidity of the environment is greater than the third preset threshold, it is determined that the paper jam reason is that the environment is humid; in the case that the water content of the printing paper is greater than the fourth preset threshold, it is determined that the paper jam reason is that the water content of the printing paper is large. If other printing parameters are also detected, the corresponding paper jam reasons can also be determined in this way. For different paper jam reasons, the target object of the paper jam risk information prompt is different. Some paper jam reasons, such as the wear of the paper feeding part, need to be solved by professional personnel. Some paper jam reasons can be solved by the user himself. Therefore, according to the paper jam reason, the target object of the paper jam risk information prompt is determined. Then the paper jam risk information of the printing device is sent to the target object. In this way, the printing device can be maintained in time, thereby improving the work efficiency.

[0057] Optionally, S402, the processor determines the target object of the paper jam risk prompt according to the paper jam reason, including:

[0058] In the case that the paper jam reason comes from the user, the processor determines that the target object is the user of the printing device.

[0059] In the case that the paper jam reason comes from the non-user, the processor determines that the target object is the user of the printing device and / or the maintenance personnel of the printing device.

[0060] The paper jam reason caused by the height of the printing paper, the humidity of the printing environment and the water content of the printing paper belongs to the user. The paper jam reason can be eliminated by the user, and the printing device maintenance personnel does not need to solve it. Therefore, in the case that the paper jam reason comes from the user, the target object of the paper jam risk prompt is determined as the user of the printing device. The paper jam reason caused by the wear of the paper feeding part belongs to the non-user. The paper jam reason needs to be solved by professional printing device maintenance personnel. Therefore, in the case that the paper jam reason comes from the non-user, the target object can be determined as the user of the printing device. After the paper jam risk information is sent to the user, the printing device maintenance personnel is notified to solve it. Alternatively, the target object can be determined as the printing device maintenance personnel. The paper jam risk information is directly sent to the device maintenance personnel. Alternatively, the target object can be determined as the user of the printing device and the printing device maintenance personnel, so as to avoid the omission of the paper jam risk prompt information by any one of the user and the maintenance personnel. In this way, according to the paper jam reason, the appropriate prompt object is determined, which is beneficial to the timely and effective solution of the paper jam problem.

[0061] Alternatively, in the case that the paper jam reason comes from the user (too many printing papers, etc.), the screen displays “there is a paper jam risk” and the paper jam reason. In the case that the paper jam reason comes from the non-user (wear of the paper feeding part), the screen displays “there is a paper jam risk” and the paper jam reason, or sends prompt information to the mailbox, telephone or the like of the printing device maintenance personnel or the printing device. The prompt information can include risk result, risk position, reason, printer position and the like, so as to quickly locate the problem and accurately solve it by the maintenance personnel or the user. Alternatively, the paper jam risk and the paper jam reason are voice broadcasted at the same time of sending and displaying the paper jam risk information, so as to enable the user to discover the paper jam risk of the printing device in time.

[0062] In combination with Figure 5 As shown in FIG. 1, the embodiment of the present disclosure provides a device for determining a paper jam risk, which comprises a detection module 51 and a determination module 52. The detection module 51 is configured to detect a printing parameter in the case that the printing device does not execute a printing task. The determination module 52 is configured to determine the paper jam risk of the printing device according to the printing parameter.

[0063] The device for determining a paper jam risk provided by the embodiment of the present disclosure is beneficial to detecting a printing parameter in the case that the printing device does not execute a printing task, so as to determine whether the printing device has a paper jam risk. In this way, it can be known whether the printing device has a paper jam risk before printing, so as to maintain the printing device in time. Therefore, the situation that the paper jam is discovered during the printing process is avoided, so as to improve the printing efficiency. Meanwhile, the waste of paper can also be avoided.

[0065] In addition, the logic instructions in the memory 61 can be implemented in the form of a software functional unit and sold or used as an independent product, which can be stored in a computer readable storage medium.

The processor 60 executes the program instructions / modules stored in the memory 61, thereby performing function applications and data processing, that is, implementing the method for determining the paper jam risk in the above-mentioned embodiments.

[0067] The memory 61 can include a program storage area and a data storage area. The program storage area can store an operating system and application programs required by at least one function; the data storage area can store data created according to the use of the terminal device, etc. In addition, the memory 61 can include a high-speed random access memory, and can further include a non-volatile memory.
