Description

Technical Field

[0001] The present invention relates to the fields of image processing technology and automatic recognition technology, and particularly to a device and method for automatically recognizing drug traceability codes. Background Art

[0002] In the modern medical system, the safety and effectiveness of drugs are directly related to the life and health of patients. With the progress of technology, drug supervision traceability code recognition devices have become important tools for ensuring the safety of patients' medication and improving the synchronous scanning efficiency of drug traceability codes. These devices not only optimize the drug management process but also ensure that every link from drug production to use can be accurately traced, building a solid defense line for the safety of patients' medication. Drug supervision traceability code recognition devices, such as drug traceability scanners, mainly rely on barcode technology and two-dimensional code technology to quickly and accurately read the information on drug packages.

[0003] However, due to possible situations such as drug stacking and side-by-side arrangement during the drug transmission process, the existing drug traceability code recognition devices may lead to inaccurate recognition of drug traceability codes or even missed inspections, which need to be solved manually and cannot achieve automatic recognition. Summary of the Invention

[0004] The present invention aims to provide a device and method for automatically recognizing drug traceability codes to solve the above technical problems and achieve the automatic recognition of drug traceability codes.

[0005] To solve the above technical problems, the present invention provides a device for automatically recognizing drug traceability codes, including: a climbing assembly line, a scanning channel, a plurality of scanning devices, and a control module, wherein:

[0006] The control end of the climbing assembly line is electrically connected to the first output end of the control module. The climbing assembly line is inclined upward, and a convex device is arranged on the surface of the climbing assembly line according to a preset design method for automatically separating stacked or side-by-side drug boxes to be recognized and transporting the drug boxes to be recognized to the scanning channel in a single transport mode;

[0007] The entrance end of the scanning channel is connected to the end of the climbing assembly line. The scanning channel is inclined downward, and the bottom, side, and top surfaces are made of transparent materials for receiving the drug boxes to be recognized;

[0008] The signal output end of the scanning device is electrically connected to the signal receiving end of the control module, and the receiving end of the scanning device is electrically connected to the second output end of the control module. A plurality of scanning devices are located at the bottom surface, side surface, top corner, and top surface of the scanning channel for automatically recognizing the drug traceability codes in any direction of the drug boxes to be recognized;

[0009] The control module is used to control the operation of the climbing assembly line, the operation of a plurality of scanning devices, and receive and store the drug traceability codes.

[0010] In the above solution, by setting an upwardly inclined climbing pipeline and a downwardly inclined scanning channel, and providing a convex device on its surface that can only hold a single medicine box, the stacked or juxtaposed medicine boxes automatically slide or separate at the convex device under the action of gravity. Therefore, a device that can automatically separate and convey medicine boxes and the scanning device starts automatically is provided, without manual control, realizing continuous automatic identification of medicine traceability codes.

[0011] Furthermore, it further includes a plurality of vision light sources. The control ends of the plurality of vision light sources are electrically connected to the third output end of the control module. The plurality of vision light sources are located on the bottom surface, side surface, and top surface of the scanning channel for scanning and lighting.

[0012] In the above solution, by adding a plurality of vision light sources in the device to illuminate the identification area in the scanning channel, the bar code of the medicine box is clearly visible, there is no shadow on the medicine box, etc. At the same time, the brightness of the vision light sources is controlled to adjust the light source brightness to a suitable level, effectively releasing the performance of the barcode scanner and enhancing the barcode scanning ability.

[0013] Furthermore, it further includes: a trigger sensor located at the starting end of the climbing pipeline. The output end of the trigger sensor is electrically connected to the trigger end of the control module, and is used to obtain a trigger signal based on the medicine box to be identified, so that the control module controls the scanning device to start automatically based on the trigger signal.

[0014] In the above solution, by setting a trigger sensor at the starting end of the climbing pipeline, when a medicine box enters the climbing pipeline, the sensor senses the medicine box and sends out a trigger signal and transmits it back to the control module. Thus, the control module controls the scanning device to start based on the trigger signal, realizing the automatic start of the scanning device without manual control.

[0015] Furthermore, it further includes: an induction sensor located at the outlet of the scanning device. The output end of the induction sensor is electrically connected to the induction receiving end of the control module, and is used to sense the identified medicine box and obtain an induction signal, so that the control module obtains an identification time interval based on the induction signal and the trigger signal. Thus, the control module obtains a turn-off signal based on the identification time interval and a preset time threshold, and controls the scanning device to automatically turn off based on the turn-off signal, realizing the automatic opening and closing of the automatic identification device for medicine traceability codes.

[0016] In the above solution, the already identified medicine box is recognized by an induction sensor, and compared and calculated with the trigger signal information of the trigger sensor to obtain the recognition time interval and compare it with a preset time threshold, so as to judge whether there is still an unrecognized medicine box in the device. When the recognition time interval is greater than the preset time threshold, it can be judged that there is no unrecognized medicine box in the device, and at this time, the scanning device is controlled to be closed, thus realizing the automatic closing of the scanning device; it can also be electrically connected to a number of visual light sources, and the automatic opening and closing of the number of visual light sources are realized in the same way, greatly prolonging the service life of the device and avoiding waste of electric energy.

[0017] Furthermore, the control module is also used to screen and store based on the medicine traceability code to obtain the target medicine traceability code.

[0018] In the above solution, the recognized medicine traceability codes are screened and stored. Since during the recognition process, when a number of code scanning devices at different angles work simultaneously, the medicine traceability codes may be scanned and uploaded repeatedly. Therefore, it is necessary to screen the repeated medicine traceability codes to finally obtain the required target medicine traceability codes and avoid situations such as repetition.

[0019] In the present invention, by setting an upwardly inclined climbing pipeline and a downwardly inclined scanning channel, after the medicine box falls into the upwardly inclined climbing pipeline and is transported upward, since the surface of the climbing pipeline is provided with a convex device that can only hold a single medicine box, the stacked or side-by-side medicine boxes to be recognized are automatically separated by the action of gravity to the end of the climbing pipeline for single transmission. Then, due to the action of inertia and gravity, they fall into the downwardly inclined scanning channel and are recognized by a number of scanning devices, realizing continuous automatic recognition of medicine traceability codes without manual control; a number of visual light sources are added on the scanning channel for scanning and lighting to enhance the recognition performance and improve the accuracy of recognizing medicine traceability codes; and by adding a trigger sensor at the starting end of the climbing pipeline to recognize when the medicine box falls into the climbing pipeline and control the automatic opening of the scanning device and the visual light source, and an induction sensor is set at the outlet of the scanning channel to calculate the recognition time interval, controlling the automatic closing function of the scanning device and the visual light source, greatly prolonging the service life of the device and reducing waste of energy consumption, providing a device that can automatically separate and transport medicine boxes and the scanning device starts automatically.

[0020] The present invention also provides a method for automatically recognizing medicine traceability codes, which is realized by using a device for automatically recognizing medicine traceability codes, and includes the following steps:

[0021] Automatically separate the stacked or side-by-side medicine boxes to be recognized, and obtain the medicine boxes to be recognized in a single transportation mode;

[0022] Automatically recognize the medicine traceability codes of the medicine boxes to be recognized in any direction.

[0023] The above solution automatically separates the medicine boxes to be identified that are stacked or placed side by side, and transports the medicine boxes to be identified to the scanning channel in a single-transport manner, preventing mutual influence between the medicine boxes. Without manual operation, it realizes the automatic identification of the medicine traceability code.

[0024] Furthermore, it also includes: scanning and illuminating the medicine boxes to be identified based on a number of visual light sources.

[0025] In the above solution, the medicine boxes to be identified are scanned and illuminated by a number of visual light sources, making the barcodes on the medicine boxes clearly visible and the medicine boxes shadowless, etc., which can effectively release the recognition performance and enhance the recognition ability.

[0026] Furthermore, it also includes: obtaining a trigger signal based on the medicine boxes to be identified, and controlling the scanning device to start automatically based on the trigger signal.

[0027] In the above solution, a trigger signal is obtained by detecting the medicine boxes to be identified, and when the trigger signal is generated, the scanning device is automatically controlled to be turned on, realizing the automatic control of the self-start of the scanning device and reducing energy consumption waste.

[0028] Furthermore, it also includes: obtaining an induction signal based on the identified medicine boxes; obtaining an identification time interval based on the induction signal and the trigger signal, and obtaining a preset time threshold, so as to obtain a turn-off signal based on the identification time interval and the preset time threshold, and controlling the scanning device to automatically turn off based on the turn-off signal, realizing the automatic opening and closing of the automatic medicine traceability code identification device.

[0029] Furthermore, obtaining an identification time interval based on the induction signal and the trigger signal, and obtaining a preset time threshold, so as to obtain a turn-off signal based on the identification time interval and the preset time threshold, and controlling the scanning device to automatically turn off based on the turn-off signal, realizing the automatic opening and closing of the automatic medicine traceability code identification device, includes:

[0030] Obtaining a trigger moment based on the trigger signal, and obtaining the current moment based on the induction signal;

[0031] Identifying the identification time interval based on the trigger moment and the current moment;

[0032] Obtaining a preset time threshold based on a preset climbing speed, preset length information, and preset redundant time, and the calculation process satisfies the following formula:

[0033]

[0034] In the formula: t m represents the maximum time interval, t o represents the preset redundant time, L1 represents the climbing pipeline length information, L2 represents the identification area length information, represents the preset climbing speed;

[0035] Obtain a turn-off signal based on the recognition time interval and the maximum time interval, and control the automatic shutdown of the scanning device based on the turn-off signal to achieve automatic recognition of the drug traceability code.

[0036] In the above solution, an induction signal is obtained by recognizing the already recognized medicine box, and the recognition time interval is obtained through comparison and calculation with the induction signal information, and is compared with the preset time threshold that can be calculated, so as to judge whether there are still unrecognized medicine boxes. When the recognition time interval is greater than the preset time threshold, it can be judged that there are no unrecognized medicine boxes in the device. At this time, the scanning device is controlled to be turned off, thus realizing the automatic shutdown of the scanning device. The automatic on and off of several vision light sources can also be realized in the same way, greatly prolonging the service life of the device and avoiding waste of electric energy.

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Embodiment 1:

[0046] This embodiment provides a device for automatically identifying a medicine traceability code, as Figure 1 shown, including: a climbing assembly line, a scanning channel, a plurality of scanning devices, and a control module, where:

[0047] The control end of the climbing assembly line is electrically connected to the first output end of the control module. The climbing assembly line is inclined upward. The surface of the climbing assembly line is provided with a protruding device according to a preset design method for automatically separating stacked or side-by-side medicine boxes to be identified and transporting the medicine boxes to be identified to the scanning channel in a single-piece transportation manner;

[0048] The entrance end of the scanning channel is connected to the end of the climbing assembly line. The scanning channel is inclined downward, and the bottom, side, and top surfaces are made of transparent materials for receiving the medicine boxes to be identified;

[0049] The signal output end of the scanning device is electrically connected to the signal receiving end of the control module, and the receiving end of the scanning device is electrically connected to the second output end of the control module. A plurality of scanning devices are located at the bottom surface, side surface, top corner, and top surface of the scanning channel for automatically identifying the medicine traceability code in any direction of the medicine boxes to be identified;

[0050] The control module is used to control the operation of the climbing assembly line, the operation of a plurality of scanning devices, and receive and store the medicine traceability code.

[0051] In the specific implementation process, when multiple medicine boxes such as side-by-side or stacked ones fall into the one-way climbing assembly line at the same time, the climbing assembly line controls the medicine boxes for one-way continuous transportation. Its front view is as Figure 2 shown. The protruding device 5 on the surface of the climbing assembly line 1 is set to a certain height that can only hold one medicine box 6, so that the upper stacked medicine boxes 6 automatically slide down due to gravity and other factors during the climbing process. The top view is as Figure 3As shown, the width is also set to only hold one medicine box 6, so that during the climbing process, the side-by-side medicine boxes 6 are automatically separated to prevent the medicines from blocking each other's medicine traceability codes, realizing the single transportation of the medicine boxes 6.

[0052] In the specific implementation process, the scanning channel is set to slope downwards, so that the medicine box 6 to be identified moves in the scanning channel in any form due to the action of inertia and gravity. By setting a number of scanning devices at the bottom surface, side surface, top corner and top surface of the scanning channel, and the scanning channel is made of transparent material, it is possible to read the medicine box 6 to be identified in any form and direction in the scanning channel, as well as single and separated multiple medicine boxes 6.

[0053] In this embodiment, by setting an upward-sloping climbing pipeline and a downward-sloping scanning channel, and providing a convex device on its surface that can only hold a single medicine box, the stacked or juxtaposed medicine boxes automatically slide or separate at the convex device under the action of gravity. Therefore, a device that can automatically separate and convey medicine boxes and the scanning device starts automatically is provided, without manual control, realizing continuous automatic identification of medicine traceability codes.

[0054] Optionally, it further includes a number of visual light sources. The control ends of the number of visual light sources are electrically connected to the third output end of the control module. The number of visual light sources are located on the bottom surface, side surface and top surface of the scanning channel for scanning and lighting.

[0055] In the specific implementation process, as Figure 4 shown, the bottom surface 8 of the scanning channel, the side surface of the scanning channel and the top surface of the scanning channel of the scanning channel 2 are all built with transparent materials, and a number of scanning devices 3 and visual light sources 4 are provided. The number of visual light sources 4 are fixedly connected to the side edges of the scanning channel 2. A free space area is formed in the scanning channel 2 as the identification area. In the identification area, the medicine box 6 only needs to move under the action of inertia and gravity, without electric power or mechanical power.

[0056] In the specific implementation process, by adding a number of visual light sources 4 to the bottom surface 8 of the scanning channel, the side surface of the scanning channel and the top surface of the scanning channel, that is, on six surfaces, and fixedly connecting them to the side edges 9 of the scanning channel, lighting the identification area in the scanning channel 2, making the barcodes of the medicine boxes 6 clearly visible on any surface and the medicine boxes 6 have no shadows, etc. At the same time, controlling the brightness of the visual light sources 4 to adjust the light source brightness to an appropriate brightness can effectively release the performance of the barcode scanner and enhance the barcode scanning ability.

[0057] Optionally, it further includes: a trigger sensor. The trigger sensor is located at the starting end of the climbing pipeline 1. Among them: the output end of the trigger sensor is electrically connected to the trigger end of the control module, and is used to obtain a trigger signal based on the medicine box 6 to be identified, so that the control module controls the scanning device 3 to start automatically based on the trigger signal.

[0058] In the specific implementation process, a trigger sensor is set at the starting end of the climbing pipeline 1. When a medicine box 6 enters the climbing pipeline 1, the sensor senses the medicine box 6 and sends out a trigger signal, which is then transmitted back to the control module. As a result, the control module controls the start of the scanning device 3 based on the trigger signal, achieving the self-start of the scanning device 3 without manual control. This automatic start control process can also be applied to several vision light sources 4.

[0059] Optionally, it further includes an induction sensor 7, which is located at the outlet of the scanning device 3. Herein, the output end of the induction sensor 7 is electrically connected to the induction receiving end of the control module, and is used to sense the identified medicine box 6 and obtain an induction signal, so that the control module obtains the recognition time interval based on the induction signal and the trigger signal. Then, the control module obtains a turn-off signal based on the recognition time interval and a preset time threshold, and controls the automatic shutdown of the scanning device 3 based on the turn-off signal, realizing the automatic opening and closing of the automatic medicine traceability code recognition device.

[0060] In the specific implementation process, when the first medicine box 6 to be identified enters the head end of the one-way climbing pipeline 1, the trigger sensor will be triggered to obtain a trigger signal, thereby enabling the control module to control the start of all scanning devices 3. When the identified medicine box 6 slides past the tail end of the scanning channel 2, the induction sensor 7 will be triggered to obtain an induction signal. When the last medicine box 6 passes the trigger sensor, there is an induction time. At this time, the trigger state of the induction sensor 7 is recorded. If it is greater than the preset time threshold and the induction sensor 7 has not been triggered all the time, it is considered that all medicine boxes 6 have exited, and the code scanning device will be closed, greatly extending the service life of the code scanning device. This automatic shutdown control process can also be applied to several vision light sources 4 to verify the service life, reduce energy consumption, and realize the automatic opening and closing of the automatic medicine traceability code recognition device.

[0061] Optionally, the control module is further used to screen and store based on the medicine traceability code to obtain the target medicine traceability code.

[0062] In the specific implementation process, the identified medicine traceability codes are automatically screened and stored. Since during the recognition process, when several code scanning devices at different angles work simultaneously, they may repeatedly scan and upload the medicine traceability codes. Therefore, it is necessary to screen the duplicate medicine traceability codes to finally obtain the required target medicine traceability codes and avoid situations such as duplication.

[0063] In this embodiment, an upwardly inclined climbing pipeline 1 and a downwardly inclined scanning channel 2 are provided, and a convex device 5 that can only hold a single medicine box 6 is arranged on the surface of the climbing pipeline 1, so as to automatically separate stacked or side-by-side medicine boxes 6 to be identified under the action of gravity and transport them to the scanning channel 2. Without manual control, continuous automatic identification of medicine traceability codes is achieved; several visual light sources 4 are added to enhance the identification performance and improve the accuracy of identifying medicine traceability codes; and the control module controls to realize the automatic on and off functions of the scanning device 3 and the visual light sources 4 by sensing signals through corresponding sensors, greatly prolonging the device life and reducing energy consumption waste, and providing a device that can automatically separate and transport medicine boxes and the scanning device starts automatically.

[0069] Optionally, it further includes: scanning and illuminating the medicine boxes to be identified based on several visual light sources.

[0075] Obtaining the trigger moment based on the trigger signal, and obtaining the current moment based on the induction signal;

[0076] Identifying the identification time interval based on the trigger moment and the current moment;

[0077] Obtaining the preset time threshold based on the preset climbing speed, the preset length information and the preset redundancy time, and the calculation process satisfies the following formula:

[0080] Obtaining the turn-off signal based on the identification time interval and the maximum time interval, so as to control the automatic shutdown of the scanning device based on the turn-off signal, thereby realizing the automatic identification of the medicine traceability code.

[0081] In the specific implementation process, the induction signal is obtained by identifying the already identified medicine box, and the identification time interval is obtained through comparison and calculation with the induction signal information, and compared with the calculable preset time threshold, so as to judge whether there are still unrecognized medicine boxes. When the identification time interval is greater than the preset time threshold, it can be judged that there are no unrecognized medicine boxes in the device. At this time, the scanning device is controlled to be turned off, thus realizing the automatic shutdown of the scanning device. The automatic opening and closing of several vision light sources can also be controlled, greatly prolonging the service life of the device and avoiding waste of electric energy.

[0083] Embodiment 3:

[0084] This embodiment provides a working process of a device for automatically identifying drug traceability codes. The device and method provided in the above embodiment are used to automatically identify drug traceability codes, as Figure 5 shown, and specifically includes the following steps:

[0085] S1: Set the parameters of several scanning devices and visual light sources through the control module;

When the trigger sensor triggers for a certain time to reach the preset time threshold (set according to the speed setting of the climbing assembly line 1) and the induction sensor 7 does not trigger all the time, the code scanning device is turned off. Several scanning devices 3 above the scanning channel 2 can scan the five surfaces of the medicine box 6 except the bottom surface through the transparent material, and the scanning device 3 at the bottom can scan the bottom of the medicine box 6 through the transparent bottom of the scanning channel 2. Therefore, the drug supervision codes of single medicine boxes or multiple separated medicine boxes in any form can be identified.
