[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] As Figure 1 shown, in an embodiment, a method for controlling the backward movement of a thin film medium is provided. This method for controlling the backward movement of a thin film medium can be applied to both a terminal and a server. In this embodiment, it is exemplified by being applied to a server. The method for controlling the backward movement of a thin film medium specifically includes the following steps:

[0033] Step 102, after receiving the thin film medium control instruction, perform a morphological detection on the thin film medium entering the thin film medium transmission structure.

[0034] Among them, the thin sheet medium control instruction refers to a command sent from the end of the thin sheet medium transmission structure for controlling the thin sheet medium in the channel of the thin sheet medium transmission structure. Specifically, after receiving the thin sheet medium control instruction, the server first performs a morphological detection on the thin sheet medium entering the thin sheet medium transmission structure. The morphology of the thin sheet medium includes the position morphology, size morphology, stacking morphology, etc. of the thin sheet medium. Optionally, multiple photoelectric sensors provided in the thin sheet medium transmission structure are used to detect the morphology of the thin sheet medium. By analyzing the detection signals, the morphology of the thin sheet medium is determined, such as the slope, thickness, width, etc. of the thin sheet medium. According to the morphology of the thin sheet medium and the preset detection conditions, it is judged whether the thin sheet medium is abnormal. For example, if the slope of the thin sheet medium is greater than the preset angle threshold in the detection conditions, the thin sheet medium is determined to be an abnormal thin sheet medium.

[0035] Step 104, when an abnormal thin sheet medium is detected, obtain the status information of the abnormal thin sheet medium.

[0036] Among them, the status information is index information used to reflect the morphology of the abnormal thin sheet medium, such as the thickness of the thin sheet medium, the width of the thin sheet medium, the size of the thin sheet medium, etc. Specifically, when detecting an abnormal thin sheet medium, obtain the status information of the abnormal thin sheet medium for subsequent further processing of the abnormal thin sheet medium based on the status information of the abnormal thin sheet medium.

[0037] Step 106, obtain the structure information of the thin sheet medium transmission structure, and perform a retraction control on the abnormal thin sheet medium according to the structure information and the status information.

[0038] Among them, the thin sheet medium transmission structure refers to the structural part at the entrance of the thin sheet medium transmission structure for transmitting the thin sheet medium, including a thin sheet medium separation wheel and multiple sensors. The structure information of the thin sheet medium transmission structure refers to the position parameters of the thin sheet medium separation wheel in the thin sheet medium transmission structure, the horizontal distance, vertical distance, etc. between multiple sensors. Specifically, the structure information of the thin sheet medium transmission structure can be obtained from the nameplate information of the thin sheet medium transmission structure or from a preset data table. It can be understood that in this embodiment, the retraction control of the abnormal thin sheet medium is performed based on the structure information of the thin sheet medium transmission structure and the status information of the abnormal thin sheet medium, that is, the influence of the thin sheet medium transmission structure and the abnormal thin sheet medium on the retraction control accuracy is comprehensively considered. That is, for abnormal thin sheet media with different status information and thin sheet medium transmission structures with different structure information, different retraction controls are realized, improving the accuracy of the retraction control of the abnormal thin sheet medium, realizing the precise control of the abnormal thin sheet medium, reducing the entry of abnormal thin sheet media into the channel of the thin sheet medium transmission structure, and improving the retraction control efficiency of the thin sheet medium and the transmission effect of the thin sheet medium.

[0039] The above-mentioned thin sheet medium retraction control method, after receiving a thin sheet medium control instruction, performs a morphological detection on the thin sheet medium entering the thin sheet medium transmission structure; when an abnormal thin sheet medium is detected, the state information of the abnormal thin sheet medium is obtained; the structure information of the thin sheet medium transmission structure is obtained, and the retraction control of the abnormal thin sheet medium is performed according to the structure information and the state information. The influence of the thin sheet medium transmission structure and the abnormal thin sheet medium on the retraction control accuracy is comprehensively considered. For abnormal thin sheet media with different state information and thin sheet medium transmission structures with different structure information, different retraction controls are implemented, improving the accuracy of the retraction control of the abnormal thin sheet medium, achieving precise control of the abnormal thin sheet medium, reducing the entry of abnormal thin sheet media into the thin sheet medium transmission structure channel, and enhancing the thin sheet medium retraction control efficiency and the thin sheet medium transmission effect.

[0040] As Figure 2 shown, in one embodiment, the thin sheet medium transmission structure includes a thin sheet medium separation wheel, and is characterized in that the retraction control of the abnormal thin sheet medium according to the structure information and the state information includes:

[0041] Step 106A, calculate the target forward distance of the abnormal thin sheet medium according to the structure information and the state information;

[0042] Step 106B, control the thin sheet medium separation wheel to move forward by the target forward distance so as to retract the abnormal thin sheet medium.

[0043] Among them, the thin sheet medium separation wheel is used in the thin sheet medium transmission structure to separate the thin sheet medium to achieve the thin sheet medium transmission operation. The target forward distance refers to the ideal distance that the abnormal thin sheet medium needs to move forward in the transmission channel of the thin sheet medium transmission structure, that is, the better position that can ensure the abnormal thin sheet medium can be retracted, thereby improving the thin sheet medium transmission effect. Then, the motor is used to control the thin sheet medium separation wheel to move forward by the target forward distance to achieve the precise retraction of the abnormal thin sheet medium, thereby improving the subsequent thin sheet medium transmission process.

[0044] In one embodiment, the thin sheet medium transmission structure includes a first sensor, a second sensor, a third sensor, a fourth sensor, and a fifth sensor. Among them, the first sensor and the second sensor are located on a first horizontal line, the thin sheet medium separation wheel is located on the first horizontal line, the third sensor and the fourth sensor are located on a second horizontal line, and the fifth sensor is located between the first horizontal line and the second horizontal line. It is characterized in that the state information of the abnormal thin sheet medium includes the width of the thin sheet medium, and the structural information includes the linear distance from the thin sheet medium separation wheel being hidden by the tongue piece and reversed to the tongue piece being exposed, the distance between the third sensor and the fourth sensor, the vertical distance from the thin sheet medium separation wheel to the fifth sensor, and the vertical distance from the fifth sensor to the second horizontal line; according to the structural information and the state information, calculate the target forward distance of the abnormal thin sheet medium, including: calculating the target forward distance according to the following formula:

[0045] Calculate the target forward distance according to the width of the thin sheet medium, the linear distance from the thin sheet medium separation wheel being hidden by the tongue piece and reversed to the tongue piece being exposed, the distance between the third sensor and the fourth sensor, the distance between the third sensor and the fourth sensor, and the vertical distance from the fifth sensor to the second horizontal line.

[0046] In this embodiment, as Figure 3 shown is a schematic structural diagram of the thin sheet medium transmission structure, where the thin sheet medium transmission structure 300, the first sensor 302, the second sensor 304, the third sensor 306, the fourth sensor 310, the fifth sensor 308, the thin sheet medium separation wheel 312, and the transmission roller 314. The first sensor 302 and the second sensor 304 are located on a first horizontal line, the thin sheet medium separation wheel 312 is located on the first horizontal line, the third sensor 306 and the fourth sensor 310 are located on a second horizontal line, and the fifth sensor 308 is located between the first horizontal line and the second horizontal line. Specifically, the target forward short distance is related to the linear distance from the thin sheet medium separation wheel being hidden by the tongue piece and reversed to the tongue piece being exposed, the distance between the third sensor and the fourth sensor, the distance between the third sensor and the fourth sensor, and the vertical distance from the fifth sensor to the second horizontal line in the structural information, and is related to the width of the thin sheet medium in the state information. More specifically, the sum value of the width of the thin sheet medium and the linear distance from the thin sheet medium separation wheel being hidden by the tongue piece and reversed to the tongue piece being exposed can be calculated, and then the distance between the third sensor and the fourth sensor, the distance between the third sensor and the fourth sensor, and the vertical distance from the fifth sensor to the second horizontal line are subtracted. The obtained difference is the target forward distance. This calculation method is simple and fast, and because it is calculated from two dimensions of structural information and state information, the target forward distance is more accurate, improving the calculation efficiency of the target forward distance.

[0047] In one embodiment, after detecting an abnormal thin sheet medium and obtaining the status information of the abnormal thin sheet medium, the method further includes: obtaining a preset number of retry thin sheet medium transmissions. If the number of thin sheet medium transmissions of the thin sheet medium transmission structure has not reached the preset number of retry thin sheet medium transmissions, determine whether re-digging is possible according to the status information of the abnormal thin sheet medium. If it is determined that re-digging is possible, continue to execute the step of obtaining the structure information of the thin sheet medium transmission structure.

[0048] In this embodiment, in order to further improve the thin sheet medium transmission process, an analysis and judgment on whether the thin sheet medium transmission structure can be re-dug is also implemented. First, obtain a preset number of retry thin sheet medium transmissions. If the number of thin sheet medium transmissions of the thin sheet medium transmission structure has not reached the preset number of retry thin sheet medium transmissions, analyze the status information of the abnormal thin sheet medium to determine whether the thin sheet medium transmission structure can be re-dug. And in the case of re-digging, continue to execute step 106 to achieve accurate rollback of the abnormal thin sheet medium, thereby improving the subsequent thin sheet medium transmission process and thin sheet medium transmission effect.

[0049] As Figure 4 shown, in one embodiment, the status information further includes the slope of the abnormal thin sheet medium, the separation time of the abnormal thin sheet medium, the width of the abnormal thin sheet medium, whether there are abnormal thin sheet medium biting holes in the abnormal thin sheet medium, and the long side dimension of the abnormal thin sheet medium. Determining whether re-digging is possible according to the status information of the abnormal thin sheet medium includes:

[0050] Step 108A, when the slope of the abnormal thin sheet medium is less than a preset angle threshold or the separation time of the abnormal thin sheet medium exceeds a preset time threshold, determine that re-digging is possible;

[0051] Step 108B, when the slope of the abnormal thin sheet medium is greater than a preset angle threshold, or the width of the abnormal thin sheet medium is less than a preset width threshold, or there are abnormal thin sheet medium biting holes, or the long side of the abnormal thin sheet medium is less than a preset length threshold, determine that re-digging is not possible.

[0052] In this embodiment, if the slope of the abnormal thin sheet medium is less than a preset angle threshold, for example, the preset angle threshold is 12°, or the separation time of the abnormal thin sheet medium exceeds a preset time threshold, that is, after the thin sheet medium is accurately rolled back, the probability of being stuck is small, determine that re-digging is possible, thereby improving the subsequent thin sheet medium transmission process. If the slope of the abnormal thin sheet medium is greater than a preset angle threshold, or the width of the abnormal thin sheet medium is less than a preset width threshold, for example, the abnormal thin sheet medium is a thin sheet medium such as a business card, or there are abnormal thin sheet medium biting holes, or the long side of the abnormal thin sheet medium is less than a preset length threshold, determine that re-digging is not possible. For example, the preset width threshold is 50 mm and the preset length threshold is 120 mm. As Figure 5As shown, it is a schematic diagram of the state of the occluded holes of the thin sheet medium A and the thin sheet medium B. Therefore, in the case of determining that re-digging is not possible, the thin sheet medium transmission process is not continued to ensure the normal operation of the thin sheet medium transmission structure.

[0053] In one embodiment, before performing the backward control on the abnormal thin sheet medium according to the structure information and the state information, it further includes: determining whether the thin sheet medium transmission port is blocked; when the thin sheet medium transmission port is blocked, determining that the thin sheet medium transmission structure cannot be re-dug; when the thin sheet medium transmission port is not blocked, determining that the thin sheet medium transmission structure can be re-dug, and continuing to execute the step of obtaining the structure information of the thin sheet medium transmission structure.

[0054] In this embodiment, before performing the backward movement of the abnormal thin sheet medium, the thin sheet medium separation wheel is reversed until the tongue piece is hidden, and the first sensor and the second sensor in the thin sheet medium transmission structure are used to detect whether the thin sheet medium transmission port is blocked. Then, the backward movement of the thin sheet medium is started. After the backward movement of the thin sheet medium is completed, when the thin sheet medium transmission port is blocked, it is determined that the thin sheet medium transmission structure cannot be re-dug; when the thin sheet medium transmission port is not blocked, it is determined that the thin sheet medium transmission structure can be re-dug, and step 106 is continued to be executed to achieve the precise backward movement of the abnormal thin sheet medium, thereby improving the subsequent thin sheet medium transmission process and the thin sheet medium transmission effect.

[0055] In one embodiment, the thin sheet medium backward control method further includes: when the slope of the abnormal thin sheet medium is less than a preset angle threshold or the separation time of the abnormal thin sheet medium exceeds a preset threshold or when the thin sheet medium transmission port is not blocked, controlling the thin sheet medium transmission structure to perform thin sheet medium transmission.
