Description

Technical Field

[0001] The present invention relates to the fields of image processing technology and automatic identification technology, and in particular to a device and method for automatically identifying a drug traceability code. 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 advancement of science and technology, drug traceability code recognition equipment has become an important tool to ensure the safety of patients' medication and improve the efficiency of synchronous scanning of drug traceability codes. These devices not only optimize the drug management process, but also ensure that every link from production to use of drugs can be accurately tracked, building a solid line of defense for patients' medication safety. Drug traceability code recognition equipment, such as drug traceability scanners, mainly rely on barcode technology and QR code technology to quickly and accurately read information on drug packaging.

[0003] However, the existing drug traceability code recognition devices may not accurately identify drug traceability codes or even miss detections due to the possibility of drug stacking or parallel arrangement during drug transportation. This requires manual intervention and cannot achieve automatic recognition. Summary of the invention

[0004] The present invention aims to provide a device and method for automatically identifying drug traceability codes, so as to solve the above technical problems and realize automatic identification of drug traceability codes.

[0005] In order to solve the above technical problems, the present invention provides a device for automatically identifying drug traceability codes, comprising: a climbing assembly line, a scanning channel, a plurality of scanning devices and a control module, wherein: 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 arranged to be tilted upward. A protrusion device is arranged on the surface of the climbing assembly line according to a preset design method, which is used to automatically separate the stacked or side-by-side medicine boxes to be identified, and transport the medicine boxes to be identified to the scanning channel according to a single transportation method. The entrance end of the scanning channel is connected to the end end of the climbing pipeline, the scanning channel is tilted downward, and the bottom, side and top surfaces are made of transparent materials for receiving the medicine box to be identified; 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. Several scanning devices are located at the bottom surface, side surface, top corner and top surface of the scanning channel, and are used to automatically identify the drug traceability code of any direction of the drug box to be identified; The control module is used to control the operation of the climbing assembly line, the operation of several scanning devices, and to receive and store drug traceability codes.

[0006] The above scheme arranges an upwardly inclined climbing assembly line and a downwardly inclined scanning channel, and arranges a protrusion device on its surface that can only catch a single medicine box, so that the stacked or parallel medicine boxes automatically slide down or separate at the protrusion device under the action of gravity, thereby providing a device that can automatically separate and transport medicine boxes and automatically start the scanning device, without the need for human control, and realizes continuous automatic identification of medicine traceability codes.

[0007] Furthermore, it also includes a plurality of visual light sources, wherein the plurality of visual light source control terminals are electrically connected to the third output terminal of the control module, and the plurality of visual light sources are located on the bottom, side and top surfaces of the scanning channel for scanning and lighting.

[0008] In the above scheme, several visual light sources are added to the device to illuminate the recognition area in the scanning channel, so that the barcode on the medicine box is clearly visible and the medicine box has no shadow, etc. At the same time, the brightness of the visual light source is controlled to adjust the brightness to the appropriate brightness, effectively releasing the performance of the scanner and enhancing the scanning capability.

[0009] Furthermore, it also includes: a trigger sensor, which is located at the starting end of the climbing assembly line, wherein: 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.

[0010] In the above scheme, a trigger sensor is set at the starting end of the climbing assembly line. When a medicine box enters the climbing assembly line, the sensor senses the medicine box and sends a trigger signal and transmits it back to the control module, so that the control module controls the start of the scanning device based on the trigger signal, thereby realizing the self-start of the scanning device without manual control.

[0011] Furthermore, it also includes: an inductive sensor, which is located at the exit of the scanning device, wherein: the output end of the inductive sensor is electrically connected to the inductive receiving end of the control module, and is used to sense the identified medicine box and obtain the inductive signal, so that the control module obtains the identification time interval based on the inductive signal and the trigger signal, so that the control module obtains the shutdown signal based on the identification time interval and the preset time threshold, and controls the scanning device to automatically shut down based on the shutdown signal, thereby realizing the automatic opening and closing of the automatic identification drug traceability code device.

[0012] In the above scheme, the induction sensor is used to identify the identified medicine box, and the information is compared and calculated with the trigger signal of the trigger sensor to obtain the identification time interval and compare it with the preset time threshold to determine whether there are any unidentified medicine boxes in the device. When the identification time interval is greater than the preset time threshold, it can be determined that there are no unidentified medicine boxes in the device. At this time, the scanning device is controlled to be turned off, thereby realizing automatic shutdown of the scanning device; it can also be electrically connected to a number of visual light sources, and the same method can be used to realize the automatic opening and closing of a number of visual light sources, which greatly extends the service life of the device and avoids waste of electricity.

[0013] Furthermore, the control module is also used to screen and store the target drug traceability code based on the drug traceability code.

[0014] In the above scheme, the identified drug traceability codes are screened and stored. During the identification process, several scanning devices at different angles may repeatedly scan and upload drug traceability codes when working at the same time. Therefore, it is necessary to screen the repeated drug traceability codes and finally obtain the required target drug traceability codes to avoid duplication.

After a medicine box falls into the upwardly inclined climbing assembly line, during the upward transmission, since a protrusion device that can only hold a single medicine box is provided on the surface of the climbing assembly line, the stacked or side-by-side medicine boxes to be identified are automatically separated under the action of gravity to reach the end of the single transmission climbing assembly line, and then fall into the downwardly inclined scanning channel due to the action of inertia and gravity, and are identified by a plurality of scanning devices without manual control, thereby realizing continuous automatic identification of medicine traceability codes; a plurality of visual light sources are added to the scanning channel for scanning and lighting to enhance the identification performance and improve the accuracy of identifying medicine traceability codes; and a trigger sensor is added at the starting end of the climbing assembly line to identify when the medicine box falls into the climbing assembly line and control the scanning device and the visual light source to automatically start, and an induction sensor is provided at the exit of the scanning channel to calculate the identification time interval, and control the automatic closing function of the scanning device and the visual light source to realize the automatic closing function of the scanning device and the visual light source, thereby greatly extending the life of the device and reducing energy waste, and providing a device that can automatically separate and transmit medicine boxes and the scanning device can automatically start.

[0016] The present invention also provides a method for automatically identifying a drug traceability code, which is implemented by using a device for automatically identifying a drug traceability code, and includes the following steps: Automatically separate the stacked or parallel medicine boxes to be identified and obtain the medicine boxes to be identified according to the single transportation mode; Automatically identify the drug traceability code in any direction of the drug box to be identified.

[0017] The above scheme automatically separates the stacked or side-by-side medicine boxes to be identified, and transports the medicine boxes to be identified to the scanning channel in a single transportation manner, thereby preventing the medicine boxes from affecting each other. Automatic identification of drug traceability codes is achieved without manual operation.

[0018] Furthermore, it also includes: scanning and illuminating the medicine box to be identified based on a plurality of visual light sources.

[0020] Furthermore, it also includes: obtaining a trigger signal based on the medicine box to be identified, so as to control the scanning device to start automatically based on the trigger signal.

[0021] In the above scheme, a trigger signal is obtained by detecting the medicine box to be identified, and the scanning device is automatically controlled to start when the trigger signal is generated, thereby realizing automatic control of the self-starting of the scanning device and reducing energy waste.

[0022] Furthermore, it also includes: obtaining a sensing signal based on the identified medicine box; obtaining an identification time interval based on the sensing signal and the trigger signal, and obtaining a preset time threshold, so as to obtain a shutdown signal based on the identification time interval and the preset time threshold, and control the scanning device to automatically shut down based on the shutdown signal, thereby realizing automatic opening and closing of the automatic identification drug traceability code device.

Indicates the preset climbing speed; A shutdown signal is obtained based on the identification time interval and the maximum time interval, so as to control the scanning device to automatically shut down based on the shutdown signal, thereby realizing automatic identification of the drug traceability code.

[0024] In the above scheme, the sensing signal is obtained by identifying the identified medicine box, and the identification time interval is calculated by comparing with the sensing signal information, and compared with the preset time threshold that can be calculated to determine whether there are any unidentified medicine boxes. When the identification time interval is greater than the preset time threshold, it can be determined that there are no unidentified medicine boxes in the device. At this time, the scanning device is controlled to be turned off, thereby realizing automatic shutdown of the scanning device. The same method can also be used to realize the automatic opening and closing of several visual light sources, which greatly extends the service life of the device and avoids waste of electricity.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: This embodiment provides a device for automatically identifying drug traceability codes. Figure 1 As shown, it includes: a climbing assembly line, a scanning channel, a plurality of scanning devices and a control module, wherein: 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 arranged to be tilted upward. A protrusion device is arranged on the surface of the climbing assembly line according to a preset design method, which is used to automatically separate the stacked or side-by-side medicine boxes to be identified, and transport the medicine boxes to be identified to the scanning channel according to a single transportation method. The entrance end of the scanning channel is connected to the end end of the climbing pipeline, the scanning channel is tilted downward, and the bottom, side and top surfaces are made of transparent materials for receiving the medicine box to be identified; 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. Several scanning devices are located at the bottom surface, side surface, top corner and top surface of the scanning channel, and are used to automatically identify the drug traceability code of any direction of the drug box to be identified; The control module is used to control the operation of the climbing assembly line, the operation of several scanning devices, and to receive and store drug traceability codes.

[0029] In the specific implementation process, when multiple medicine boxes, such as side by side or stacked, fall into the one-way climbing assembly line at the same time, the climbing assembly line controls the medicine boxes to be transported continuously in one direction, and its main view is as follows: Figure 2 As shown, the raised device 5 on the surface of the climbing assembly line 1 is set to a certain height to only hold one medicine box 6, so that the upper stacked medicine boxes 6 automatically slide down due to factors such as gravity during the climbing process. The top view is as shown in FIG. Figure 3 As shown, the width is also set to only hold one medicine box 6, so that the medicine boxes 6 arranged side by side are automatically separated during the climbing process to prevent the medicines from blocking each other's traceability codes, thereby realizing the individual transportation of the medicine boxes 6.

[0030] During the specific implementation process, the scanning channel is tilted downward so that the medicine box 6 to be identified can move in any form in the scanning channel due to inertia and gravity. By arranging a number of scanning devices on the bottom, sides, top corners and top surface of the scanning channel, and the scanning channel is made of transparent material, it is possible to read the medicine boxes 6 to be identified in any form and direction in the scanning channel, as well as single and separate multiple medicine boxes 6.

[0031] This embodiment provides an upwardly inclined climbing assembly line and a downwardly inclined scanning channel, and provides a protruding device on the surface thereof that can only catch a single medicine box, so that the stacked or parallel medicine boxes automatically slide down or separate at the protruding device under the action of gravity. Therefore, a device is provided that can automatically separate and transport medicine boxes and the scanning device is automatically started, without the need for human control, thereby achieving continuous and automatic identification of medicine traceability codes.

[0032] Optionally, it also includes a plurality of visual light sources, wherein the plurality of visual light source control terminals are electrically connected to the third output terminal of the control module, and the plurality of visual light sources are located on the bottom, side and top surfaces of the scanning channel for scanning lighting.

[0033] In the specific implementation process, Figure 4 As shown, the scanning channel bottom surface 8, the scanning channel side surface and the scanning channel top surface of the scanning channel 2 are all constructed of transparent materials, and are provided with a plurality of scanning devices 3 and visual light sources 4. The plurality 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 an identification area. In the identification area, only inertia and gravity are required to move the medicine box 6, without the need for electric power or mechanical power.

[0034] In the specific implementation process, by adding a number of visual light sources 4 on 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, six surfaces, fixedly connected to the side edge 9 of the scanning channel, the recognition area in the scanning channel 2 is illuminated, so that the barcode of the medicine box 6 is clearly visible on any surface and the medicine box 6 has no shadow, etc., and at the same time, the brightness of the visual light source 4 is controlled to adjust the brightness of the light source to an appropriate brightness, which can effectively release the performance of the scanner and enhance the scanning capability.

[0036] During the specific implementation process, a trigger sensor is set at the starting end of the climbing assembly line 1. When a medicine box 6 enters the climbing assembly line 1, the sensor senses that the medicine box 6 sends a trigger signal and transmits it back to the control module, so that the control module controls the scanning device 3 to start based on the trigger signal, thereby realizing the self-start of the scanning device 3 without manual control; this automatic start control process can also use a number of visual light sources 4.

[0037] Optionally, it also includes: an induction sensor 7, which is located at the exit of the scanning device 3, wherein: 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 the induction signal, so that the control module obtains the identification time interval based on the induction signal and the trigger signal, so that the control module obtains the shutdown signal based on the identification time interval and the preset time threshold, and controls the scanning device 3 to automatically shut down based on the shutdown signal, thereby realizing the automatic opening and closing of the automatic identification drug traceability code device.

[0038] In the specific implementation process, when the first medicine box 6 to be identified enters the head end of the one-way climbing assembly line 1, the trigger sensor will be triggered and a trigger signal will be obtained, so that the control module controls all scanning devices 3 to start. When the identified medicine box 6 slides over the tail end of the scanning channel 2, the sensing sensor 7 will be triggered to obtain a sensing signal. When the last medicine box 6 passes the trigger sensor, there is a sensing time. At this time, the trigger state of the sensing sensor 7 is recorded. If it is greater than the preset time threshold and the sensing sensor 7 has not been triggered, it is considered that all medicine boxes 6 have been produced, and the scanning device will be turned off, which greatly extends the life of the scanning device. This automatic shutdown control process can also be used for several visual light sources 4 to verify the service life, reduce energy consumption, and realize the automatic opening and closing of the automatic identification drug traceability code device.

[0039] Optionally, the control module is also used to filter and store the target drug traceability code based on the drug traceability code.

[0040] In the specific implementation process, the identified drug traceability codes are automatically screened and stored. During the identification process, several scanning devices at different angles may repeatedly scan and upload drug traceability codes when working at the same time. Therefore, it is necessary to screen the repeated drug traceability codes and finally obtain the required target drug traceability codes to avoid duplications.

[0043] The above scheme automatically separates the stacked or side-by-side medicine boxes to be identified, and transports the medicine boxes to be identified to the scanning channel in a single transportation manner, thereby preventing the medicine boxes from affecting each other. Automatic identification of drug traceability codes is achieved without manual operation.

[0044] Optionally, it also includes: scanning and illuminating the medicine box to be identified based on a plurality of visual light sources.

[0045] In the specific implementation process, the medicine box to be identified is scanned and illuminated by a number of visual light sources, so that the barcode of the medicine box is clearly visible and the medicine box has no shadow, etc., which can effectively release the recognition performance and enhance the recognition ability.

[0048] Optionally, it also includes: obtaining a sensing signal based on the identified medicine box; obtaining an identification time interval based on the sensing signal and the trigger signal, and obtaining a preset time threshold, to obtain a shutdown signal based on the identification time interval and the preset time threshold, and controlling the scanning device to automatically shut down based on the shutdown signal, thereby realizing automatic opening and closing of the automatic identification drug traceability code device.

[0049] Optionally, the identification time interval is obtained based on the sensing signal and the trigger signal, and a preset time threshold is obtained, so as to obtain a shutdown signal based on the identification time interval and the preset time threshold, and the scanning device is automatically turned off based on the shutdown signal, so as to realize the automatic opening and closing of the automatic identification drug traceability code device, including: Acquire the trigger time based on the trigger signal, and acquire the current time based on the sensing signal; Identify a time interval based on a trigger moment and a current moment; The preset time threshold is obtained based on the preset climbing speed, the preset length information and the preset redundant time, and the calculation process satisfies the following formula: Where: t mrepresents the maximum time interval, t o Indicates the preset redundant time, L1 indicates the length information of the climbing pipeline, and L2 indicates the length information of the identification area. Indicates the preset climbing speed; A shutdown signal is obtained based on the identification time interval and the maximum time interval, so as to control the scanning device to automatically shut down based on the shutdown signal, thereby realizing automatic identification of the drug traceability code.

[0050] In the specific implementation process, the sensing signal is obtained by identifying the identified medicine box, and the identification time interval is calculated by comparing with the sensing signal information, and compared with the calculable preset time threshold to determine whether there are any unidentified medicine boxes. When the identification time interval is greater than the preset time threshold, it can be determined that there are no unidentified medicine boxes in the device. At this time, the scanning device is controlled to be turned off, thereby realizing the automatic shutdown of the scanning device. It can also control the automatic opening and closing of several visual light sources, greatly extending the service life of the device and avoiding energy waste.

[0051] The present embodiment provides a method for automatically identifying drug traceability codes, which automatically separates the stacked or side-by-side drug boxes to be identified, transports the single one-way drug boxes to be identified to the scanning channel, and controls the visual light source to scan and illuminate the drug boxes to be identified to enhance the recognition performance and improve the accuracy of identifying drug traceability codes; and by obtaining the trigger signal and the sensing signal, the recognition time interval is calculated and compared with the preset time threshold, the device is automatically controlled to open when the trigger signal is obtained, and the device is automatically controlled to close when the recognition time interval is greater than the preset time threshold, thereby realizing automatic opening and closing functions, greatly extending the life of the device and reducing energy waste; and realizing continuous automatic recognition of drug traceability codes.

[0052] Embodiment three: This embodiment provides a workflow using an automatic identification device for drug traceability codes, using the device and method provided in the above embodiment to automatically identify drug traceability codes, such as Figure 5 As shown, the specific steps include: S1: Setting several scanning devices and visual light source parameters through the control module; S2: The control module obtains a trigger signal when the trigger sensor senses the medicine box to be identified, and automatically turns on a number of scanning devices and visual light sources based on the trigger signal; S3: The climbing assembly line automatically separates the stacked or parallel medicine boxes to be identified, and obtains the medicine boxes to be identified according to the single transportation mode; S4: A plurality of scanning devices automatically identify the drug traceability code of the drug box in any direction to be identified, and upload the drug traceability code to the control module for screening and storage to obtain the target drug traceability code; S5: The control module obtains the sensing signal based on the sensing sensor, obtains the identification time interval based on the sensing signal and the trigger signal, thereby obtaining the shutdown signal based on the identification time interval and the preset time threshold, and controls the scanning device to automatically shut down based on the shutdown signal.

[0053] In the specific implementation process, when multiple medicine boxes 6 in a side-by-side or stacked situation fall into the one-way climbing assembly line 1 at the same time, the trigger sensor will sense the medicine and start several scanning devices 3 to scan the code. The one-way climbing assembly line 1 continuously moves without stopping to transfer the medicine box 6 to the scanning channel 2, which will automatically separate the stacked and side-by-side medicines. In the downward-inclined scanning channel 2, the medicine box 6 to be identified falls freely due to the action of gravity and inertia. At this time, the scanning device 3 scans the freely falling medicine box 6 in any form to obtain the medicine traceability code. When the trigger sensor is triggered for a certain time and reaches the preset time threshold (set by the speed setting of the climbing assembly line 1), when the induction sensor 7 is not triggered, the scanning device is turned off.
