Description

Technical Field

[0001] The present application relates to the technical field of storage and traceability management of traditional Chinese medicine, and in particular to a method for full-chain information-based traceability management of traditional Chinese medicine using RFID technology. Background Art

[0002] At present, the Chinese medicine industry uses barcode or QR code technology for management. Each management link requires a barcode scanner to manually scan the barcode or QR code on the Chinese medicine package. This is OK if the number of codes to be scanned is small and the code can be scanned directly. However, if there are many Chinese medicine packages and the woven bags on the Chinese medicine packages cannot be scanned directly, it is necessary to open each package and scan the code, which is obviously inconvenient and prone to missed scans and repeated scans. The code scanning operation is used in many links, such as purchasing warehousing or returning goods, transferring or returning goods from the main warehouse to the sub-warehouse of the group, prescription adjustment, inventory counting, etc. There are N links that repeat the operation N times, and the workload increases N times. In order to balance, the actual application can only manage the production batch number level, that is, the same production batch number is only scanned once, and the new production batch number is replaced and scanned again. This management method reduces the workload of code scanning, and production batch number management can also be achieved to meet the most basic management. However, the number of Chinese medicine packages involved in the same batch number can reach tens of thousands of packages at most. Management by batch number is obviously increasingly inconsistent with the hospital's gradually strengthened refined management needs, and it is also easy to cause many problems in the actual management process. However, with the deepening of digital management requirements, the policy requirements for full-chain traceability of Chinese medicine pieces are constantly proposed. The use of barcode management is obviously not in line with current management needs, and breakthroughs and innovations must be made in technical solutions.

[0003] On the other hand, in the actual work process, prescription adjustment is the stage that needs the most supervision and control. First, it is directly facing patients to ensure the efficiency of adjustment, and second, it is necessary to strictly follow the prescription requirements to ensure the safety of clinical drug use, and no mistakes can be made. Under such high-intensity requirements, if you deliberately scan the code, it will distract your attention, reduce work efficiency, and increase the possibility of errors. The existing human resources of the hospital cannot support the scanning of each medicine package during the adjustment process. If you cannot scan the code, you cannot bundle the current prescription with a specific Chinese medicine package used for the prescription adjustment. You can only stay at the level of production batch number and cannot perform specific positioning. Once a problem with the decoction piece is found, it cannot be traced back to the specific medicine package, and you don’t know which patients the medicine package was distributed to. The operability of realizing targeted drug recall is not great, and if the same batch of Chinese medicine is recalled, it is also difficult to implement if there are too many patients involved. Therefore, it is difficult to make effective traceability and recall of problematic Chinese medicine in actual work. Summary of the invention

[0004] The purpose of this application is to overcome the problems in the prior art that Chinese medicine packages need to be scanned one by one before they can be put into storage, and that once a problem occurs, it is impossible to trace and investigate the specific Chinese medicine package, and to provide a full-chain information traceability management method for Chinese medicine using RFID technology.

[0005] In the first aspect, a method for information-based traceability management of the entire chain of traditional Chinese medicine using RFID technology is provided, including:

[0006] An ultra-high frequency RFID tag, the name of the Chinese medicine, a unique identification code, a production batch number and a serial number are set on the Chinese medicine packaging bag, and the Chinese medicine information is written into the ultra-high frequency RFID tag;

[0007] Obtaining a purchase list, wherein the purchase list includes the name of the traditional Chinese medicine and the corresponding unit, quantity and supplier;

[0008] The Chinese medicine packages with UHF RFID tags are put into storage through a channel door with UHF RFID tag recognition capability, and the UHF RFID tag of each Chinese medicine package is automatically identified to obtain the corresponding Chinese medicine information;

[0009] Generate an arrival list based on the identified Chinese medicine information;

[0010] Compare the purchase list and the arrival list to obtain the comparison results, and visualize the comparison results;

[0011] The Chinese medicine information that does not match the Chinese medicine information in the purchase list and the arrival list is displayed to the staff in the form of pictures, texts and / or voice broadcasts, so that the staff can inspect and accept the Chinese medicine packages with mismatched Chinese medicine information;

[0012] After the acceptance is completed, the Chinese medicine packages are put into storage and the acceptance results are uploaded. The purchase entry form and purchase acceptance form are automatically generated according to the acceptance results;

[0013] The business type, occurrence time, operator and warehouse inventory after the business is completed are recorded at the business node of traditional Chinese medicine, where the business nodes include but are not limited to purchasing warehousing, acceptance and return, allocation and collection by the adjustment team, return to the warehouse by the adjustment team, adjustment prescription out of the warehouse and inventory count, so as to query the full chain information of traditional Chinese medicine from warehousing to adjustment prescription out of the warehouse.

[0014] In some possible implementations, the Chinese medicine information includes a unique identification code, a minimum packaging gram weight, a packaging method and a measurement unit, a number of small packages in a packaging bag, a production batch number, a serial number, and a supplier identification code;

[0015] The business type, occurrence time, operator and inventory of the traditional Chinese medicine at each management node are queried through at least one of the traditional Chinese medicine information.

[0016] In some possible implementations, the traditional Chinese medicine information is written into the EPC storage area of ​​the RFID according to the agreed coding rules and is set to a locked state.

[0017] In some possible implementations, the Chinese medicine packaging bag is also provided with a minimum packaging gram weight, packaging method and measurement unit, number of small packages in the packaging bag, and supplier.

[0018] In some possible implementations, when the working group is replenishing stocks together, an inventory upper limit is set for the dispensing table, and the difference between the inventory upper limit and the current inventory is calculated and displayed visually. The replenishment Chinese medicine packages are placed above the dispensing table equipped with a first short-range RFID antenna, and the ultra-high frequency RFID tags of the replenishment Chinese medicine packages are automatically identified, and the corresponding Chinese medicine packages are automatically shipped out and recorded.

[0019] In some possible implementations, during non-centralized replenishment, the Chinese medicine packages are placed above a dispensing table equipped with a first short-range RFID antenna, and the ultra-high frequency RFID tags of the Chinese medicine packages are automatically identified and the corresponding Chinese medicine packages are automatically shipped out or put into storage, and the business category and operator are uploaded and recorded.

[0020] In some possible implementations, a second short-range RFID antenna is installed on the dispensing shelf of each dispensing group and a second long-range RFID antenna is installed in the warehouse to monitor the inventory of each Chinese medicine on the dispensing shelf and in the warehouse in real time, and an out-of-stock alarm is issued when the inventory of Chinese medicine on the dispensing shelf and in the warehouse is lower than a preset inventory lower limit, wherein the out-of-stock alarm includes the name of the Chinese medicine and the current inventory quantity, wherein, in the RFID tag identification process, RFID tags that do not follow the agreed coding rules and RFID tags that are not on the purchase list are not identified.

[0021] In some possible implementations, when performing prescription adjustment, a prescription is obtained from the adjustment platform and the prescription is visually displayed, the ultra-high frequency RFID tag of the Chinese medicine package above the adjustment table equipped with a first short-range RFID antenna is automatically identified to obtain the EPC code, the EPC code is parsed to obtain the Chinese medicine information on the adjustment table, and it is determined whether the Chinese medicine package on the adjustment table belongs to the current prescription based on the parsed Chinese medicine information. If the Chinese medicine package belongs to the current prescription, the EPC code and the corresponding Chinese medicine information are bound to the corresponding Chinese medicine in the prescription, the name of the Chinese medicine in the Chinese medicine information is voice broadcast, and the corresponding Chinese medicine details in the visually displayed prescription are displayed as 1. If there is a package received, the count is accumulated and the Chinese medicine information of the received package is bound to the corresponding Chinese medicine in the prescription, and the ultra-high frequency RFID tag on the empty medicine package generated by the package connection is invalidated. If the Chinese medicine package does not belong to the current prescription, a voice alarm is issued and the abnormal medicine name is visually displayed.

[0022] In some possible implementations, when taking inventory of the dispensing shelves and warehouses, the Chinese medicine packages in the dispensing shelves and warehouses are placed in batches above the dispensing table equipped with a first short-range RFID antenna, and the Chinese medicine package information is automatically identified and a detailed inventory record is generated, which includes the operator, time, Chinese medicine name, and profit and loss amount.

[0023] In some possible implementations, the production batch numbers of the Chinese medicine packages that fail the acceptance inspection are added to a blacklist, and an automatic alarm is triggered if the production batch numbers in the blacklist are put into storage again.

[0024] The present application has the following beneficial effects: by adopting the Chinese medicine package management method of the present application, not only is it not necessary to scan the code for each Chinese medicine package for warehousing operation, but hundreds of ultra-high frequency RFID tags can be read per second in the channel door with ultra-high frequency RFID tag recognition capability, so that the warehousing recognition operation of thousands of Chinese medicine packages can be completed within seconds and the warehousing record can be automatically completed, and the arrival list is generated according to the supplier unit in combination with the purchase list, and the purchase entry form and the purchase acceptance form are automatically generated after sampling each different batch and the qualified production batch number is accepted, and it can also be connected to the HIS system and uploaded to the designated database table, and the purchase entry form can be completed by selecting to import in the HIS system, which greatly improves the efficiency of warehousing and ordering, and can complete the business records of various management links such as the purchase and warehousing, return, group collection, group return to the warehouse, prescription adjustment and outbound delivery of Chinese medicine packages, and warehouse inventory, etc., relying on ultra-high frequency RFID tags to realize automatic identification, reading and recording, thereby realizing the full-process traceability management of the EPC code of the ultra-high frequency RFID tag from the purchasing supplier to the patient.

[0036] Example

[0037] like Figure 3 As shown, the warehouse 200 and the dispensing table 300 are modified: a passage door 100 with a first long-range RFID antenna 101 built in is installed on both sides of the entrance of the warehouse 200 to read the UHF RFID tag in the passage door 100 to realize the identification of the medicine packages entering and leaving the warehouse 200, and a plurality of second long-range RFID antennas 201 are installed in the warehouse 200 to read the UHF RFID tag in the warehouse 200 to realize the identification of the Chinese medicine packages in the warehouse 200, as shown in FIG. Figure 4As shown, a plurality of first short-range RFID antennas 301 are installed below the dispensing table 300 to read the UHF RFID tags on the dispensing table 300 to identify the Chinese medicine packages on the dispensing table 300, such as Figure 5 As shown, a plurality of second short-range RFID antennas 901 are installed under the layer plate 903 of the dispensing shelf 900 of the dispensing group to read the UHF RFID tags on the dispensing shelf 900 to identify the Chinese medicine packages on the dispensing shelf 900, such as Figure 6 As shown, the first long-range RFID antenna 101 is connected to the first RFID reader-writer 102, the second long-range RFID antenna 201 is connected to the second RFID reader-writer 202, the first short-range RFID antenna 301 is connected to the third RFID reader-writer 302, the second short-range RFID antenna 901 is connected to the fourth RFID reader-writer 902, the first RFID reader-writer 102, the second RFID reader-writer 202, the third RFID reader-writer 302 and the fourth RFID reader-writer 902 are all electrically connected to the main control module 400, which is used to collect the EPC code recognized by the reader-writer and decode it according to the preset coding rules to obtain the Chinese medicine information corresponding to the EPC code. The main control module 400 is connected to at least one terminal device 500, a display 600 and a speaker. Device 700, wherein the terminal device 500 includes smart devices such as desktop computers, notebooks, mobile phones and tablets, which are used to upload relevant information through the terminal device 500 and realize the viewing and tracing of traditional Chinese medicine information and alarm information. The display 600 and the speaker 700 are used for the visual display and voice broadcast of relevant information. Of course, the terminal device 500 can also be connected to an alarm light 801 and an alarm 802. The alarm light 801 distinguishes different alarm types by lights of different colors, and the alarm 802 distinguishes different alarm types by different alarm sounds. In this application, a short-range RFID antenna refers to an RFID antenna with an identification distance set within a range of 10 cm-60 cm, and a long-range RFID antenna refers to an RFID antenna with an identification distance set within a range of 1 m-30 m.

[0038] like Figure 1 As shown, the embodiment of the present application involves a method for information-based traceability management of traditional Chinese medicine using RFID technology, including:

[0039] S100, setting an ultra-high frequency RFID tag, the name of the Chinese medicine, a unique identification code, a production batch number and a serial number on the Chinese medicine packaging bag, and writing the Chinese medicine information into the ultra-high frequency RFID tag;

[0040] It should be noted that the frequency range of UHF RFID tags is 860 MHz-960MHz, and the specific frequency varies from region to region. Compared with ordinary RFID tags, the reading distance of UHF RFID tags is farther, up to several meters or even more than ten meters. The storage area of ​​UHF RFID tags includes the following parts:

[0041] Reserved area: contains the destruction password and access password, which are used for tag destruction and access control.

[0042] EPC area: used to store the unique identifier of the item, usually readable and writable, used for identification and management of the item.

[0043] TID area: stores the unique identification number of the label, used to distinguish different labels, usually only readable and not writable, and is often used as an anti-counterfeiting function.

[0044] User area: used to store user-defined data, readable and writable, with a capacity of up to several K. Functions vary depending on tag type and manufacturer.

[0045] The above four areas together constitute the storage structure of the UHF RFID tag, supporting the storage and fast reading, anti-counterfeiting, destruction and other needs of the electronic tag.

[0046] In this embodiment, the EPC storage area of ​​the UHF RFID tag is used, and the Chinese medicine information includes a unique identification code, the minimum package weight, the packaging method and measurement unit, the number of small packages in the packaging bag, the production batch number, the serial number and the supplier identification code. The coding rules are as follows:

[0047] Six-digit unique identification code, in the preset database, the unique identification code corresponds to a Chinese medicine name, four-digit small package weight, of which the left three digits are the integer part of the small package, and the fourth digit is the decimal part. Two-digit packaging method and measurement unit, three-digit number of small packages in the packaging bag, six-digit production batch number, four-digit serial number, different production batch numbers of the same Chinese medicine can use the same serial number, and the same production batch number of the same Chinese medicine must use different serial numbers. The last two digits are the supplier identification code, and the supplier identification code corresponds to different suppliers in the preset database. This overall combination can ensure the uniqueness of each EPC number, so that the EPC code can be used to identify a specific medicine package in each link of the internal circulation of the hospital, and the EPC code is unique.

[0048] Field 1: The 6-digit unique identification code of the Chinese medicine. For example, the unique identification code can be found in the "Basic Code of Chinese Medicine Pieces of Zhejiang Cancer Hospital". Each unique identification code corresponds to a Chinese medicine, for example, the unique identification code: 125303 corresponds to mugwort, the unique identification code: 124311 corresponds to lily, and so on.

[0049] Field 2: Minimum packaging code of 4 digits, the first 3 digits represent the integer part of the specification, and the fourth digit is the decimal part, such as 0015 represents 1.5. For example, 0090 represents 9, and 0030, 0120, 0150, and 0300 represent 3, 12, 15, and 30 respectively.

[0050] Field 3: 2-digit code for packaging method and unit of measurement:

[0051] The meaning of the first digit is: 1-gram, 2-kilogram, 3-piece, 4-piece, 5-stick, 6-piece, 0-other.

[0052] The second digit indicates the packaging code, 1-pack, 2-box, 3-bottle, 0-other.

[0053] For example: Code 11 means grams / bag, 12 means grams / box, and 21 means kilograms / bag.

[0054] Field 4: 3-digit number of packets in the package, for example: 200 packets are represented by 200, 50 packets are represented by 050. The weight is calculated based on the drug package specifications, packaging method and measurement unit, and the number of packets.

[0055] Field 5: 6-digit production batch number, for example: 240913.

[0056] Field 6: 4-digit serial number, unique identification of a batch of Chinese medicine. For example: 0001, 0002, 0003 sequential code.

[0057] Field 7: 2-digit supplier number. 01-Company A, 02-Company B.

[0058] For example, according to the above coding rules, the name of the Chinese medicine is mugwort, the corresponding unique identification code is 125303, the small package is 6 grams, 200 bags per bag, the production batch number is 241205, the serial number is 0008, and the supplier is 02, Company B. The coding result is as follows: 125303006011200241205000302, a total of 27 digits.

[0059] For example, according to the above coding rules, the Chinese medicine name: Lily, the corresponding unique identification code: 124311, small package 1.5 grams, 050 bags per bag, production batch number: 241208, serial number 0008, supplier is 01, company A. The coding result is as follows: 124311001511050241208000801, a total of 27 digits.

[0060] When printing the UHF RFID label on the traditional Chinese medicine packaging bag, the 27-bit EPC code is simultaneously written into the EPC storage area in the RFID and set to a locked state, that is, the content cannot be modified.

[0061] In order to enable relevant personnel to quickly obtain relevant information about Chinese medicine without RFID tag identification, in addition to printing ultra-high frequency RFID tags on Chinese medicine packaging bags, the serial number, minimum packaging gram weight, packaging method and measurement unit, number of small packages in the packaging bag, production batch number and supplier are also printed on the Chinese medicine packaging bags, so that relevant personnel can directly obtain relevant information about Chinese medicine by checking the Chinese medicine packaging bags, and can accurately find the corresponding Chinese medicine package by generating batch numbers and serial numbers.

[0062] In this embodiment, the application of UHF RFID technology of wireless radio frequency technology can solve the problems encountered by barcodes or QR codes. First, there is no need to display barcodes and scan codes. When selecting the UHF RFID reading signal strength range, the UHF long-distance antenna deployment is set to a range of 1-30 meters, reading hundreds of tags per second, and the UHF short-distance antenna deployment can be set to an identification range of about 10-60 cm. Chinese medicine packages are generally controlled within 1.5 kilograms, and UHF RFID electronic tags are posted on the medicine packages. The actual application scenario is that the number of warehousing is mostly less than 1,000 kilograms, and the number of RFID electronic tags is calculated as 1,000, that is, 1,000 tags are read at one time when purchasing and warehousing, and the identification and reading can be completed in a few seconds.

[0063] It is worth noting that most of the medicine bags contain plant roots, stems, leaves and flowers, and a small amount of animals or minerals are not pure metals, which can be effectively identified by UHF signals. It should be noted that in the identification environment, when storing utensils or transporting carts during identification, RFID electronic tags should avoid contact with metal materials, and shielding measures should be taken outside the metal materials, such as: wrapping wood boards, plastics and other materials outside the metal to prevent the UHF signal from being absorbed by the metal material, resulting in the RFID reader not receiving the signal and causing the tag to miss reading. These matters should be resolved in advance and can be used normally after the test is stable.

[0064] S200, obtaining a purchase list, wherein the purchase list includes the name of the Chinese medicine and the corresponding unit, quantity and supplier, wherein the purchase list is uploaded by the user, and includes the name of the purchased Chinese medicine and the corresponding unit, quantity and supplier name;

[0065] S300, the Chinese medicine packages with UHF RFID tags are put into storage through the channel door 100 with UHF RFID tag recognition capability, and the UHF RFID tag of each Chinese medicine package is automatically identified to obtain the corresponding Chinese medicine information;

[0066] S400, generating an arrival list according to the identified Chinese medicine information;

[0067] Specifically, when the warehousing channel passes through the channel door 100, the first long-range RFID antenna 101 in the channel door 100 combines with the first RFID reader 102 to automatically identify and record the EPC code of the ultra-high frequency RFID tag of each Chinese medicine package, and generates an arrival acceptance form according to the supplier unit in combination with the purchase list. After sampling each different batch, the qualified production batch number is automatically generated for the purchase entry form. Connect to the HIS system and upload it to the specified database table. Select import in the HIS system to complete the purchase entry form, which greatly improves the efficiency of warehousing order opening. The above is the operation flow of purchase entry.

[0068] S500, obtaining a comparison result by comparing the purchase list and the arrival list, and visually displaying the comparison result;

[0069] S600, displaying the Chinese medicine information of the Chinese medicines in the purchase list and the arrival list that do not match to the staff in the form of pictures, texts and / or voice broadcasts, so that the staff can inspect and accept the Chinese medicine packages of the Chinese medicines that do not match;

[0070] Specifically, the EPC code in the read-in RFID is automatically compared with the purchase list according to the supplier and the specifications of the Chinese medicine pieces, and the name, specification, weight, number of packages of the Chinese medicine package in the purchase list, as well as the weight and number of packages actually read are marked respectively, that is, the Chinese medicine information in the purchase list is compared with the Chinese medicine information actually received (that is, the Chinese medicine information obtained by identifying the ultra-high frequency RFID tag on the Chinese medicine package through the first long-distance RFID antenna 101 in the channel door 100). The comparison results are divided into three situations: full response (that is, the Chinese medicine information is completely corresponding), partial response (that is, the Chinese medicine information is partially corresponding, and some information is not corresponding) and no response (that is, the Chinese medicine information is completely non-corresponding). There are three different alarm light colors, for example: full response is bright green, partial response is bright blue, and no response is bright red. During the acceptance, the staff can see at a glance by observing the color of the alarm light, focusing on the Chinese medicine with partial response (blue) and no response (red), and unpacking and acceptance according to the serial number classified by the production batch number. If the acceptance result is qualified, it will be put into storage, and the status of the Chinese medicine will be changed to the storage-ready status.

[0071] S700. After the acceptance is completed, the Chinese medicine packages are put into storage and the acceptance results are uploaded. The purchase entry form and purchase acceptance form are automatically generated based on the acceptance results.

[0072] Specifically, when all the Chinese medicine packages are accepted, they are automatically uploaded to the HIS system intermediate table and imported into the HIS system interface to quickly and efficiently complete the purchase order. The purchase acceptance form is automatically generated in combination with the acceptance results. The data is recorded for query and statistical analysis, and timely feedback is given to the supplier as needed. According to the feedback, the supplier will adjust and improve relevant measures in a timely manner to improve the quality of supply services and ensure the stable and reliable supply of Chinese medicine.

[0073] In addition, based on the acceptance results, the production batch numbers of Chinese medicine packages that failed the acceptance quality inspection are set to a blacklist. When the production batch numbers on the blacklist are put into the warehouse again, an alarm will be automatically triggered to control the quality of medicines in all directions and dimensions, ensuring the continuity and sharing of quality acceptance information. Regularly collect the acceptance problem list, combine it with the procurement management method to make corresponding rewards and punishments, use actual data for comparison and comparison, and assist suppliers in the quality supervision of supply.

[0074] It should be noted that the process of allocating from the warehouse 200 to each dispensing table 300 is divided into two situations. The first is centralized replenishment: the replenishment medicine packages are concentrated on a small cart, and the cart passes through the designated area and the channel door 100. The operation is similar to purchasing and warehousing by using a long-distance antenna plus an RFID reader. At the time of centralized replenishment, the system calculates the difference between the existing inventory and the upper limit inventory according to the inventory upper limit set by the dispensing table 300, that is, the inventory upper limit number minus the existing inventory number, and displays the number of medicine packages. If the decimal part of the calculation result is greater than or equal to 0.5 packages, it is calculated as 1 package. On the contrary, if it is less than 0.5 packages, it is treated as 0, that is, no replenishment is made. The replenishment medicine packages are placed above the dispensing table 300 equipped with the first short-range RFID antenna 301. The EPC code of the ultra-high frequency RFID tag on the medicine package is recognized by the reader, and the business system completes the group allocation out of the warehouse.

[0075] The second method is to install a second short-range RFID antenna 901 on the dispensing shelf 900 of each dispensing group and a second long-range RFID antenna 201 in the warehouse 200 during the non-centralized replenishment period (in actual work, the dispensing group is responsible for dispensing for patients according to the prescription. During the medicine dispensing process, the dispensing group members grab the Chinese medicine in the prescription and the corresponding quantity from the dispensing shelf 900 where a certain amount of Chinese medicine is placed, and pack and distribute them to the patient after verification. The dispensing shelf 900 of each dispensing group and the warehouse 200 are equipped with a second short-range RFID antenna 901 to monitor the inventory of each Chinese medicine in the dispensing shelf 900 and the warehouse 200 in real time. , and when the inventory of Chinese medicine in the dispensing shelf 900 and the warehouse 200 is lower than the preset inventory lower limit, an out-of-stock alarm is issued, wherein the out-of-stock alarm includes the name of the Chinese medicine and the current inventory quantity. The system automatically detects that a Chinese medicine in the dispensing shelf 900 is lower than the inventory lower limit, and then issues an out-of-stock alarm for the dispensing team. This type of replenishment is sporadic replenishment. The system automatically detects that a Chinese medicine in the warehouse is lower than the inventory lower limit, and then issues an out-of-stock alarm for the warehouse, realizing fully automatic monitoring of the inventory of each dispensing team and the inventory of the warehouse 200. When the inventory of a Chinese medicine in stock is lower than the preset inventory, it can Automatically send out-of-stock alarms and announce the names of Chinese medicines, so that relevant staff can be reminded to replenish stocks immediately. Use a short-range antenna combined with an RFID reader / writer, place the replenishment medicine package on the dispensing table 300 equipped with the first short-range RFID antenna 301, select the group and replenishment button on the tablet software interface, and the system will automatically read the EPC code of the ultra-high frequency RFID tag at this moment. After clicking "complete", the system records the group replenishment operation, including: information related to the replenished Chinese medicine, as well as information such as the operator, business category and operation time, for subsequent traceability. Similar to sporadic replenishment The operation also includes: the group medicine package is returned to the warehouse 200, the purchase of sporadic warehousing or return is managed by the close-range antenna plus RFID reader, and the EPC code of the ultra-high frequency RFID tag of the medicine package is identified to determine the specific Chinese medicine package. In this way, each package of decoction pieces can be accurately recorded and managed in each business node, and the business category, time, operator and other information of each medicine package entering and leaving the warehouse are recorded in a similar way. The EPC code of the ultra-high frequency RFID tag of the medicine package can be used to view the current status and circulation process of the medicine package in the system, thereby realizing the full-link record of the entry and exit of the Chinese medicine package.

[0076] In order to save costs, it is not necessary to set an ultra-high frequency RFID tag on each small package of Chinese medicine packaging bag. It is only necessary to set an ultra-high frequency RFID tag on a medium package or a large package of Chinese medicine packaging bag containing multiple small packages of Chinese medicine. When the dispensing team is dispensing and dispensing medicines according to the prescription, first, the medium package or large package of each Chinese medicine in the prescription is taken out from the dispensing shelf 900 and placed on the dispensing table 300, so that the first short-range RFID antenna 301 under the dispensing table 300 can read the ultra-high frequency RFID tag on the packaging bag of the medium package or the large package to identify the corresponding Chinese medicine information, and compare the identified Chinese medicine information with the Chinese medicine information in the prescription. If every Chinese medicine on the prescription is on the dispensing table, and every Chinese medicine on the dispensing table 300 is also on the prescription, it means that the category of the Chinese medicine is correct, and then the staff is prompted to pick up the medicine from the dispensing table 300 according to the patch. The staff will put each patch of Chinese medicine (each patch of Chinese medicine refers to The patient's daily medication, in order to facilitate the patient's medication, all the Chinese medicines contained in the prescription (one patch is used as a unit for dispensing medicine and each patch of Chinese medicine is packaged together separately) are placed in a storage box and weighed. After peeling, the weight of each patch of Chinese medicine in the prescription can be obtained. If the weight difference of each patch of Chinese medicine is within 3 grams, it is normal. If it is greater than 3 grams, it is abnormal and requires manual inspection to ensure that the weight of each patch of Chinese medicine is equal. Finally, each patch of Chinese medicine is packaged separately and then packaged together for delivery. In addition, since the adjustment team will not be able to use up a medium or large package of Chinese medicine every time when adjusting and dispensing medicine according to the prescription, it is necessary to unpack, that is, take out a certain number of small packages of Chinese medicine from the medium or large package. Therefore, there will be a large error when using the second short-range RFID antenna 901 on the adjustment shelf 900 to monitor the inventory. In order to more accurately monitor the real inventory of the adjustment team, the inventory monitoring of the adjustment team can also be achieved by the following method:.

[0077] The management application of the prescription dispensing process (i.e., the process of picking medicine according to the prescription) is to lay the first short-range RFID antenna 301 under each dispensing table 300. After receiving the prescription task, the prescription is displayed on the large screen, which is convenient for the dispensing team members to view the content of the prescription. According to the operating procedures, the Chinese medicine package is placed in the designated area of ​​the dispensing table 300. The system automatically reads the EPC code of the ultra-high frequency RFID tag on the Chinese medicine package through the first short-range RFID antenna 301 and the third RFID reader 302 under the dispensing table 300, and automatically parses the EPC code to determine whether the medicine package belongs to the current prescription. If it meets the voice broadcast of a certain medicine name, the corresponding prescription details on the large screen will display the quantity 1, and if there is a package received, it will be counted cumulatively. Otherwise, if it is not within the prescription range, "Warning of invalid medicine" will be broadcast, and the abnormal medicine name will be displayed on the large screen to indicate an alarm.

[0078] In order to obtain prescriptions during the dispensing process and automatically identify, parse and record Chinese medicine packages on the dispensing table, it is necessary to build a dispensing platform with ultra-high frequency RFID recognition function. The doctor uploads the patient's prescription to the dispensing platform or directly edits the prescription on the dispensing platform. The dispensing platform can allocate the prescription to the corresponding dispensing team according to the preset allocation rules, and the dispensing team will perform medicine dispensing and packaging operations according to the prescription.

[0079] During the prescription adjustment process, the prescription form is obtained from the adjustment platform and displayed visually, the ultra-high frequency RFID tag of the Chinese medicine package above the adjustment table equipped with the first short-range RFID antenna is automatically identified to obtain the EPC code, the EPC code is parsed to obtain the Chinese medicine information on the adjustment table, and the Chinese medicine package on the adjustment table is judged according to the parsed Chinese medicine information whether it belongs to the current prescription form. First, it is ensured that the Chinese medicine package used in each prescription form is identified. If there is any unrecognized medicine package, the system will refuse to save it, issue a voice alarm, and visually display the abnormal medicine name to ensure that all Chinese medicines in the prescription details are identified and recorded. If the Chinese medicine package belongs to the current prescription, the EPC code and the corresponding Chinese medicine information will be bound to the corresponding Chinese medicine in the prescription, the name of the Chinese medicine in the Chinese medicine information will be announced by voice, and the corresponding Chinese medicine details in the visually displayed prescription will be displayed with a quantity of 1. If a package is received during the adjustment process, that is, the first Chinese medicine package of a certain medicine is not enough for adjustment and distribution, and the second package is required to be used, this situation is called a package reception. The received medicine package is also required to be identified and recorded. Before the adjustment is saved, the system must receive the EPC code invalidation information of the ultra-high frequency RFID tag of the received package, that is, empty Medicine packages should be discarded in the system in a timely manner to ensure the authenticity of the data of medicine packages in the system, laying a good foundation for subsequent inventory and other work. Among them, the methods of discarding include physical destruction (i.e., destroying the antenna or chip of the RFID tag by cutting, drilling or crushing, so that it cannot work properly), electromagnetic interference (i.e., using strong electromagnetic field equipment to interfere with the RFID tag, damaging its internal circuit and making it invalid), writing destruction commands (i.e., writing destruction commands through the RFID reader to make it lose the function of being read, that is, it cannot be read normally and is deemed to be non-existent.) etc. In this way, the EPC code of each Chinese medicine used in the prescription is recorded, and the corresponding Chinese medicine name, packaging method, quantity, weight, production batch number, serial number, supplier name and other information can be obtained through the EPC coding rules for subsequent information tracing.

[0080] S800, such as Figure 2As shown, when performing business operations, the UHF RFID tag on the Chinese medicine package is identified by the RFID antenna to obtain the EPC code, and the corresponding Chinese medicine information is automatically identified and parsed according to the EPC code, and the corresponding business is completed under manual assistance. The business type, occurrence time, operator and warehouse inventory after the business is completed are recorded at the business node of the Chinese medicine, wherein the business nodes include but are not limited to purchase warehousing, acceptance return, transfer group transfer and use, transfer group return to the warehouse, transfer prescription out of the warehouse and inventory count, wherein the inventory count includes the transfer group transfer shelf 900 inventory and warehouse Inventory count is carried out in the warehouse to query the whole chain information of Chinese medicine from storage to prescription and delivery. When querying information, the business type, occurrence time, operator and inventory of Chinese medicine in each management node can be queried through at least one of the following information: unique identification code, minimum packaging gram, packaging method and measurement unit, number of small packages in the packaging bag, production batch number, serial number and supplier identification code. The combination of the two types of information can more accurately query the relevant information of the Chinese medicine to be queried, including business type, time of business occurrence, business operator and current inventory, etc. As time accumulates, the recorded Chinese medicine It will continue to increase. Querying through a combination of multiple information is conducive to accurately querying the Chinese medicine to be queried, thereby improving the query efficiency. Querying only through the serial number can query multiple different Chinese medicines with the same serial number, but querying with the serial number + Chinese medicine name can exclude the relevant information of non-query target Chinese medicines, so as to find the target Chinese medicine we want to query more quickly. For example: there are the following two Chinese medicine information: 1. Serial number: 0001, Chinese medicine name: lily, production batch number: 241208.... 2. Serial number: 0001, Chinese medicine name: mugwort, production batch number: 241205... .; If you only query by serial number: 0001, at least the relevant information of serial number: 0001, Chinese medicine name: Lily, production batch number: 241208... and serial number: 0001, Chinese medicine name: Artemisia argyi, production batch number: 241205... will be found. If we query by serial number: 0001+Chinese medicine name: Lily, the relevant information of the Chinese medicine name being Artemisia argyi can be excluded, so that the business type, occurrence time, operator and current inventory recorded for the serial number: 0001 and the Chinese medicine name being Lily can be accurately queried.

[0081] Specifically, by querying the prescription, the name of the Chinese medicine, unique identification code, production batch number and serial number information of any medicine in the prescription can be viewed. Through its serial number, the business type, occurrence time, operator and inventory status of the medicine package at each management node in the hospital can be viewed. For example: what date was it purchased from which supplier, the inspection status, when was it transferred to which adjustment group, when did it start to be used, what is the current status, and in which prescriptions is this medicine package used, etc.

[0082] It is applied in the inventory work of the warehouse 200 and the dispensing shelf 900. The inventory of the stock medicine packages needs to be taken regularly or irregularly in the warehouse 200 or the dispensing shelf 900 of each dispensing group. When taking inventory, attention should be paid to the whole package and the number of small packages that have been unpacked. The inventory method adopts the first short-range RFID antenna 301 installed under the dispensing table 300. The inventory group and shelf number are selected in the tablet operation interface. The system interface displays which Chinese medicines are on the shelf. The display method is business card-like, and the display content includes the name of the medicine, specification, package quantity and total weight. When there are Chinese medicines that have been unpacked (that is, the Chinese medicines in medium or large packages are unpacked and a certain amount of small packages of Chinese medicines are taken out from them, so that the number of small packages of the Chinese medicines in the medium or large packages does not correspond to the number in the ultra-high frequency RFID tag on the packaging bag), it is necessary to manually verify and correct the package quantity. Put the medicine package to be counted on the dispensing table 300, click to start the inventory, and the EPC code, Chinese medicine name, specification and small package quantity calculated by the system recognized by the RFID reader are displayed. The number of unopened medicine packages remains unchanged, and the number of unopened packages is changed to the actual number of small packages counted. If there is no small package corresponding to the EPC code, the number is changed to 0. This completes the inventory work. If the filled quantity is greater than the number calculated by the system, it is a surplus. Conversely, if the filled quantity is less than the system quantity, it is a shortage. The difference is the profit and loss number. If there is a profit and loss number, the system automatically generates a detailed inventory record.

[0083] It is worth noting that in a fixed area, high-power long-distance RFID antennas and RFID readers are deployed, combined with supporting application systems, to encode the EPC codes of the UHF RFID tags according to the agreed rules. When reading in, tags that are not in the agreed coding rules are not processed and excluded to improve reading efficiency. For EPC codes within the tag rules, the purchase list drug package range condition restrictions are added, that is, the EPC codes of UHF RFID tags that are not in the purchase list are not processed. In this way, the interference of invalid tags and other RFID tags is greatly reduced under the double swiping conditions, so that the EPC codes read into the system are valid target tags. The target EPC codes for subsequent related processing are all within the purchase list, and the business data is single and orderly. If the purchase list drug packages are reduced, it is only necessary to notify the supplier not to ship or not to put them into storage after arrival. If the purchase list is increased, it can be increased accordingly in the application system.

[0084] From the analysis of the above business node scenarios, the EPC code recognition and reading of the UHF RFID tag in this embodiment does not require complex manual operations (such as scanning codes one by one with a handheld barcode scanner). According to the normal operation process, the medicine package is placed in the designated area. The system automatically recognizes and reads the EPC code of the business node. Combined with the business scenario logic, the system automatically records the corresponding business records and automatically completes the business logic status and calculation of the medicine package. It provides a practical case of technical solutions for the full-chain information management system of Chinese herbal medicine pieces, and truly opens up a new channel for the full-chain information management of Chinese herbal medicine pieces.

[0085] With the automatic completion of the identification and recording of the medicine package during the adjustment period, as well as the scenario-based real-time voice broadcast and error alarm, the EPC code of the received medicine package is invalidated. The automatic recording and query of all business nodes from procurement from suppliers to patients has been realized. The management of the entire link corresponds to the actual operation process one by one, providing sufficient and reliable information traceability support for future user complaints, quality control, error analysis, and accountability.

[0086] In this embodiment, the EPC code in the UHF RFID tag is used as the unique identifier of the Chinese medicine package, and then combined with the UHF RFID reader, the UHF long-distance antenna or the UHF short-distance antenna can be used for automatic identification in the air. The identification distance can be adjusted according to the business scenario requirements. The power setting interface program is connected in the application system business logic, and the power is automatically set according to the corresponding business requirements in the application system. The latest Internet of Things MQTT protocol is used to complete the instant response, the corresponding UHF antenna and reader are deployed in the business environment, and the RFID reader is used to start the relevant operations according to the operator's instructions, and the relevant business nodes such as the entry, exit, adjustment, and inventory of Chinese medicine are recorded and processed in the application system, so as to complete the corresponding Chinese medicine warehousing, acceptance and return, group transfer and use, group return to warehouse 200, adjustment prescription out of the warehouse, and inventory counting.

[0087] The above are only preferred specific implementations of the present application; however, the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved ideas of the present application within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
