Description
Technical Field
The invention relates to the field of medicine management, in particular to a medicine checking device and method.
Background
In a medical system, because the amount of drugs used is large and is related to human health, precise batch management is required, and the current drug management generally manages the drugs by manually combining a database to put the drugs in storage, check the drugs, and take the drugs out of the storage.
However, the existing medicine management method cannot automatically and correspondingly record the medicine information of a certain medicine and the storage position of the medicine into the database, and the storage position of the medicine needs to be manually checked and then recorded after the medicine is put in the database, so that the time is consumed, the efficiency is low, and the error is easy to make when large-batch medicines are processed.
The prior art discloses an intelligent positioning method and device for infrared and RFID combined medicines, wherein the method comprises the following steps: placing the medicine which is pasted with the RFID electronic tag and can reflect infrared rays into a medicine rack; moving a movable workbench provided with an infrared sensor and an RFID reader-writer along a medicine rack, and detecting and recording the position of the movable workbench; when the mobile workbench reaches one medicine storage position, the infrared sensor detects whether the position is provided with a medicine according to the existence of an infrared ray external reflection signal, if so, the RFID reader-writer reads the coding information and the medicine information in the RFID electronic tag of the medicine, and the coding information, the medicine information and the position of the medicine storage position are bound and stored in a database in a corresponding relationship; and repeating the previous step until the moving workbench finishes walking each medicine storage position on the medicine rack.
However, if only the scene that whether the medicine bottle in the medicine storage box is the designated medicine needs to be confirmed, the structure is too complicated, and the cost of the device is high. For example, the medicine boxes on the ambulance are only provided with one type of medicine in the same medicine box, and whether the medicine box is the specified medicine or not only needs to be determined, which is related to the life safety of the patient needing to be rescued. In addition, the prior art needs to move to read the medicine information, and the speed is slow.
Disclosure of Invention
In order to solve the above problems, a primary object of the present invention is to provide a medicine inventory device based on image recognition, which has a simple structure and can quickly inventory medicines.
Another object of the present invention is to provide a medicine checking device based on image recognition, which has low cost, good effect and is easy to be widely popularized.
Still another object of the present invention is to provide a medicine checking method based on image recognition, which can simply, quickly and accurately check medicines.
In order to achieve the purpose, the invention provides a medicine checking device based on image recognition, which comprises a camera mechanism and more than one medicine placing mechanism, wherein the medicine placing mechanism comprises a medicine box, a medicine placing position for placing medicines with recognizable marks is arranged in the medicine box, and the camera mechanism corresponds to the recognizable mark position to obtain an image with the recognizable marks. The invention also comprises a system, the image with the identifiable mark is shot and obtained by the camera shooting mechanism, the image can be transmitted to the system in a wired or wireless mode, and the system judges whether the medicine in the medicine box is correct according to the preset comparison, thereby avoiding the irrecoverable error caused by the wrong medicine, and simultaneously determining whether the quantity of the medicine is correct, thereby judging whether the medicine box is full of the medicine. Through above-mentioned simple structure setting, can check the medicine fast to adapt to some first aid occasions better. In particular, the camera mechanism may be a conventional camera, wherein the camera directly corresponds to the identifiable mark on the medication within the cartridge. The recognizable mark can be the character information of the medicine itself, or the mark additionally arranged for distinguishing the medicine information.
Furthermore, the medicine placing mechanism further comprises a shielding box and an RFID reader, and the medicine box and the RFID reader are both arranged in the shielding box. In the invention, the RFID label is attached to the medicine through the arrangement of the shielding box and the RFID reader. When the shielding box works specifically, the shielding box is used for shielding reading signals of the RFID reader, so that the RFID reader can only read RFID label information on medicines in the shielding box, and when the medicine placing mechanisms are used side by side, the RFID reader cannot read medicine RFID label signals in other shielding boxes. After the RFID reader reads the RFID label information on the medicine in the shielding box, the information can be transmitted to the system in a wired or wireless mode, and the system judges whether the medicine in the medicine box is correct or not according to preset comparison, so that the irrecoverable errors caused by the wrong medicine placement are avoided, and meanwhile, whether the quantity of the medicine is correct or not can be determined, and whether the medicine box is filled with the medicine or not is judged.

When the number of inventory is required, reading the TID code and the data code is selected according to the inventory requirement, if the data code is selected to be read, the same RFID label can be read for countless times, if the TID code is selected to be read, the RFID label is read only once, the RFID label can not be read again, and repeated inventory can be prevented.
Furthermore, in order to avoid the problem of repeated statistics caused by the fact that the same RFID label is read for multiple times, the invention also provides an algorithm for preventing the repeated statistics, the same RFID label can be counted only once within a set time during checking, and once the information is completely repeated, newly counted data are automatically ignored. This further ensures the accuracy of the inventory.
Further, the medicine information includes information on the type and quantity of the medicine. The type information of medicine is mainly used for confirming whether the medicine of placing is wrong, and quantity information is mainly used for confirming whether the quantity of medicine accords with the demand of using, if the medicine box is filled up, whether the medicine quantity in the medicine box is enough for the use of a certain use scene.
Further, the specific steps of the system for analyzing the identifiable mark in the picture are as follows: and after the picture is uploaded to the system, the picture is identified according to an identification model trained in advance by the system, so that the medicine information is obtained.
Further, the training process of the recognition model is as follows: uploading the picture, marking the characteristics in the picture, performing self-training by adopting a deep learning model according to the characteristics marked in the picture, performing test verification on the trained model, and continuously optimizing the self-training process according to the test verification result until the standard which can be used is reached.
