Description

Technical Field

[0001] This invention belongs to the technical field of intelligent drug management equipment, and specifically relates to an intelligent drug management cabinet. Background Technology

[0002] Specially controlled drugs, such as narcotic drugs and psychotropic drugs, are addictive, abuse-prone, and pose high safety risks. Therefore, they must strictly comply with national and industry regulatory standards throughout the entire process of circulation, use, recycling, and inventory management. This process must be fully traceable, auditable, and tamper-proof to prevent drug loss, abuse, misdelivery, and other safety incidents, and to ensure medical safety and public health order. Currently, the management equipment for specially controlled drugs is mostly traditional medicine cabinets or simple intelligent cabinets. They generally adopt a management mode of manual registration and two-dimensional or one-dimensional barcode scanning and verification. The processes of drug entry, exit, issuance, and recycling still require a lot of manual intervention, resulting in low automation and problems such as operation record errors and out-of-sync inventory data. The equipment is not timely in sensing and alarming abnormal situations, such as unauthorized access, over-dosage issuance, exceeding environmental parameter limits, and abnormal drug movement. It lacks dynamic threshold early warning and multi-level linkage alarm mechanisms, which cannot effectively prevent drug safety risks and is difficult to adapt to the increasingly strict regulatory policies and clinical management scenarios.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides, for example Figure 1-5 The illustrated intelligent drug management cabinet includes a cabinet body 1. A human-computer interaction module and an identity verification module are installed on the upper part of one side of the cabinet body 1. A first camera 9 for monitoring the surrounding environment of the cabinet body 1 and a 4G antenna 8 for enhancing communication signals are installed on the top of the cabinet body 1. The first camera 9 is an ordinary security camera. The human-computer interaction module is used to input and display operation instructions for drug inventory, entry and exit, and recycling. The human-computer interaction module is a touch screen 3, which is embedded in the upper part of one side of the cabinet 1. The fingerprint reader 6 is located below the touch screen 3, and the face recognition camera 2 is located above the touch screen 3. The administrator can perform system operations such as configuring user permissions, setting time duration, and adjusting RF power through the touch screen 3. The operator can only perform operations such as medicine entry and exit, recycling, and inventory. The touch screen 3 is a 21-inch touch screen with a built-in model number RK3568.

[0019] The identity verification module adopts a dual-person authentication mode. Each login requires two operators to verify the user's identity through any combination of two authentication methods. The identity verification module includes an identity card recognition module 4, a barcode recognition module 5, a fingerprint reader 6, a face recognition camera 2, and a virtual numeric password input unit. The barcode recognition module 5, the fingerprint reader 6, and the identity card recognition module 4 are integrated on the same plane. Each time a user logs in, they can choose any two authentication methods from the identity card recognition module 4, the barcode recognition module 5, the fingerprint reader 6, the face recognition camera 2, and the numeric password input unit to verify the user's identity.

[0020] Among them, the ID card recognition module 4 uses a CPH-B601 reader for recognition.

[0021] The barcode recognition module 5 is used to scan the barcode or QR code on medicine bottles. The RFID tag recognition automatically generates an entry record, which includes information such as the batch number, place of origin, volume and name of the medicine. The barcode recognition module uses the Youku E4000 scanning module. The fingerprint reader 6 uses the AS608 of photonics IoT, which uses a micro-capacitor array to physically capture the fingerprint's ridges and convert them into digital features, and then compares them with fingerprints in the fingerprint database. The face recognition camera 2 is an embedded face recognition camera module that integrates optical imaging and feature recognition algorithms. It completes identity authentication by combining optical imaging and feature recognition algorithms. First, the face recognition camera 2 completes the acquisition of face images. Then, the feature recognition algorithm detects and locates the face in the image. Next, the face alignment is used to correct the posture and angle. Then, the key facial features are extracted and converted into standardized mathematical feature vectors. The mathematical feature vectors are compared and calculated with a pre-entered feature library, and finally, the comparison result is output, achieving identity verification with a response time of seconds, non-contact, and high accuracy. The virtual digital password input unit is specifically a software interaction unit implemented through the virtual keyboard interaction interface on the touch screen 3. The authentication module performs the following authentication process: A1. Two operators initiate login via the touchscreen, entering the dual-authentication working state; A2. Each operator must choose any two of the four methods—ID card recognition, fingerprint recognition, facial recognition, and digital password—for verification. Once both methods are successfully verified, the operator has completed the verification process. A3. Once both operators have completed and passed the combined verification, the login is deemed valid. A4. Access is granted according to hierarchical permissions. Administrators can configure user permissions, adjust time duration, and adjust RF power. Operators can only perform basic operations such as medicine entry and exit, recycling, and inventory. After successful verification, the electric lock module will automatically unlock, and the operator can enter the operation interface. If the verification fails, the equipment will be locked immediately and an audible and visual alarm will be triggered, while an abnormal log will be recorded. By employing a four-fold identity verification module—identity card recognition, fingerprint, facial recognition, and digital password—combined with dual-person authentication and two-level access control, the security of drug handling is significantly improved, meeting the control requirements for special drugs.

[0022] A cabinet door is installed on one side of the cabinet body 1. An electric lock module for controlling the opening and closing of the cabinet door is installed on the cabinet door. Multiple electric drawers 12 that can be customized for storing or recycling medicines are installed inside the cabinet body 1 located at the cabinet door and on the cabinet body 1 below the identity verification module. Each electric drawer 12 has an RFID drawer plate 7 installed at the bottom. The RFID drawer plate 7 has multiple holes 15. Each electric drawer 12 is equipped with an independent motor drive board. The RFID drawer plate 7 has a power interface 14 for connecting to the motor drive board. The electronic lock module includes a first electronic lock 10 and a second electronic lock 11. The first electronic lock 10 and the second electronic lock 11 are fixed side by side on one side of the cabinet door. Both the first electronic lock 10 and the second electronic lock 11 are KOB magnetic electronic locks. The cabinet door can only be opened when both electronic locks are open. The RFID drawer plate 7 integrates a main control chip and independent array antennas 16. Multiple array antennas 16 on the RFID drawer plate 7 form a multi-channel antenna array. Each array antenna 16 is formed by integrating a helical antenna and a radio frequency switch group composed of multiple cascaded single-pole double-throw radio frequency switches on the RFID drawer plate 7 according to a fixed rule. This fixed rule is set based on the number and position of the holes 15. Each array antenna 16 has one radio frequency switch group, and each hole 15 is equipped with a corresponding helical antenna, forming an independent drug label identification unit. The radio frequency switch group has a multi-channel tree-like switch matrix topology, and its main input terminal is connected to the main control chip. Multiple final stage output terminals are connected one-to-one with the multiple spiral antennas. The main control chip adopts an STM32 system microcontroller, which outputs multiple control words through the GPIO or SPI interface to directly control the RF switches of each node in the RF switch group. The spiral antennas of different aperture positions 15 in the array antenna 16 are selected in a time-division manner according to a preset timing sequence. The one-to-one accurate positioning and identification of the drug RFID tag is achieved by switching the RF link in a time-division manner. The main control chip is powered by the corresponding motor drive board. The RFID drawer board 7 has a working voltage of 12V and a maximum current of 3A. The external communication interface of the RFID drawer board 7 is a 485 interface 13. The interconnection terminals are HX-3 and VH-2 elbow interfaces.

[0023] The radio frequency (RF) switch used is model SKYWORKS AS179-92LF, employing UHF ultra-high frequency electromagnetic waves with a frequency range of 900-925MHz, and conforming to the EPCGen2 (18000-63) protocol specification. Since this model is a single-pole double-throw (SPDT) switch, a single switch only has a one-to-two selection capability. Therefore, in this embodiment, multiple RF switches are cascaded to construct a multi-channel RF switch matrix covering all aperture positions 15, enabling the entire RF switch group to have multi-channel selection capability. The main control chip sends high / low level control signals to different levels of RF switches according to the specified aperture address, establishing a unique RF link from the main input to the target spiral antenna. This allows for time-division switching and sequential selection of spiral antennas at different aperture positions 15 according to the main control chip's instructions, ensuring that only one spiral antenna operates at any given time, thus achieving one-to-one accurate positioning and identification of the drug label. The spiral antenna is a radiating element specifically responsible for transmitting and receiving the label signal, possessing good directionality and strong anti-interference capabilities. Specifically, when the RFID drawer board 7 accurately locates and identifies RFID tags on medicine bottles one-to-one, the main control chip issues an inventory command, the motor drive board supplies power to the RFID drawer board 7, and then the RF switch sequentially selects a single spiral antenna in sequence while turning off all other spiral antennas. The selected spiral antenna transmits a UHF RF signal in the 900–925MHz band, following the EPCGen2 protocol, to accurately read the RFID tag of the medicine in the corresponding hole 15. After the hole 15 is read, the RF switch turns off this antenna and switches to the next one, thus completing the traversal scan of each hole 15. During the identification process, the system obtains the core information of the medicine tag's EPC and UID, and binds the tag information with the corresponding hole 15 number to achieve accurate positioning of one tag per hole, effectively avoiding cross-reading and misreading problems. After all hole 15 are scanned, the identification data is packaged and sent back to the main board to complete the inventory data update and display it synchronously on the touch screen 3.

[0024] Through one-to-one precise positioning and identification, cross-reading and misreading can be avoided, and precise traceability of medicines can be achieved throughout the entire process from warehousing to recycling. The RFID drawer panel 7 supports RF power setting configuration. The scanning time for a single hole 15 is on the order of hundreds of milliseconds, and the scanning time for all holes 15 is about 16 seconds. The cabinet 1 also supports automatic inventory after the electric drawer 12 is closed. The inventory method is RFID tag identification combined with object detection and counting. Specifically, when setting the RF power, the power value is set through the touch screen 3 interface and transmitted to the main control chip on the RFID drawer panel 7 through the 485 interface 13 to complete the power setting. During automatic inventory, the main control program issues an inventory command, which is transmitted to the RFID interface board via RS485. The main control chip completes RS485 protocol parsing and command recognition, and acquires tags for each hole 15 according to the specified hole 15 or by traversal. The traversed data is then arranged and returned to the main control program through the 485 interface 13. The electric drawer 12 includes a drawer box for storing medicines and a drive mechanism installed at the bottom of the drawer box. The drive mechanism is used to open and close the drawer box. The drive mechanism is electrically connected to a motor drive board. The drawer box adopts a tray-type structure. The tray for storing bottled medicines is a perforated tray, and different sizes of medicines are distinguished by the diameter of the holes. The drive mechanism includes a DC motor and a lead screw. The motor drive board uses an L298N chip to output a PWM square wave control signal to drive the DC motor to rotate. The DC motor and the motor drive board are installed inside the cabinet 1 below the drawer, without occupying the medicine storage space. One end of the lead screw is connected to the output shaft of the DC motor, and the other end of the lead screw... The end connects to the rear of the drawer box, and the optical grating anti-pinch sensor is installed at the drawer opening to perform real-time anti-pinch detection. When a drawer opening command is received, the main board sends a control signal, the motor driver board outputs a PWM signal, and the DC motor rotates forward to drive the lead screw to push the drawer box out smoothly. When a drawer closing command is received, the DC motor reverses, and the lead screw pulls the drawer box back. If the optical grating sensor detects an obstacle during the closing process, it will immediately trigger the motor to stop running and issue a voice prompt. After the obstacle is removed, the closing action resumes. After the drawer is fully opened or closed, the motor stops working, and the lead screw transmission mechanism achieves self-locking to prevent the tray from accidentally sliding, ensuring operational safety and stability.

[0025] The cabinet 1 is equipped with a hardware board module and a sensor module. The hardware board module is electrically connected to the sensor module, the electric lock module, the identity verification module, the human-machine interaction module, the RFID drawer board 7, and the motor drive board.

[0026] The sensor module includes a temperature and humidity sensor for collecting data inside the cabinet 1 and the electric drawer 12, a vibration sensor for detecting vibrations in the entire cabinet 1, and a grating anti-pinch sensor that triggers the motor to stop and provides a voice prompt when an obstacle is detected during closing. The grating anti-pinch sensor is installed at the electric drawer 12. When an obstacle is detected during closing, it immediately triggers the motor to stop and provides a voice prompt. The closing action resumes after the obstacle is removed, improving operational safety. The grating anti-pinch sensor uses a 13610 through-hole infrared light interruptor to detect hand or other object obstructions. The temperature and humidity sensors are installed inside each drawer of the cabinet 1 to collect temperature and humidity data in real time, ensuring compliance with regulations for drug storage environment. The temperature and humidity sensors use AM2301 from Auson to collect temperature and humidity data in real time, and the vibration sensors use WTVB01-BT50 to identify horizontal and vertical vibrations. The interior of the cabinet 1 is divided into multiple support plates, which support the electric drawer 12 and internal hardware. The vibration sensors are installed on the support plate in the middle of the cabinet 1, arranged parallel to the support plate, to prevent the cabinet 1 from being illegally pried open.

[0027] By using temperature and humidity sensors, vibration sensors, and optical grating anti-pinch sensors, combined with inbound and outbound timer alarms and audible and visual alarms, the system can achieve comprehensive monitoring of the cabinet 1 and the storage status of medicines, and respond promptly to abnormal situations. At the same time, the anti-pinch and automatic opening and closing design of the electric drawer 12 improves the safety and automation of operation.

[0028] The hardware board module includes a motherboard and a medicine cabinet communication board. The motherboard is communicatively connected to the human-machine interaction module, the identity verification module, the motor drive board, and the RFID drawer board 7. The medicine cabinet communication board is electrically connected to the electric lock module and the sensor module. The motherboard is a Rockchip RK3568 development board, which supports four USB ports, one 1Gbps network port, and two RS232 ports, and communicates with the medicine cabinet communication board using RS232. The medicine cabinet communication board is a TX302 development board, which supports RS232, RS485, and USB communication. Specifically, the motherboard adopts a control method combining centralized control, command-based control, and bus communication. As the core control unit of the whole machine, it establishes connections with various functional modules through communication interfaces such as RS232, RS485, and USB, and uniformly completes information collection, logic processing, command issuance, and status monitoring. That is, the motherboard receives operation commands from the human-machine interaction module and verification results from the identity verification module, processes them internally, and outputs control signals to the lower-level modules. It controls the automatic opening and closing of the electric drawer 12 through the motor drive board, realizes time-division scanning and accurate identification of medicine labels through the RFID drawer board 7, indirectly controls the electric lock module and sensor module through the medicine cabinet communication board, and collects status information such as temperature, humidity, vibration, and anti-pinch in real time. It judges, records, and stores abnormal situations, drives the sound and light alarm module to execute alarms, and then uploads the data to the background system through the external communication interface to realize the automated, integrated, and safe management of the whole machine.

[0029] The hardware card module is also equipped with a TF card storage unit for local storage of drug data, operation records, and abnormal information to prevent data loss. The TF card storage unit uses a Kingston TF128G memory card for data storage.

[0030] The cabinet 1 is also equipped with an external communication interface module, which is embedded in the side wall of the cabinet 1 and is used to interface with external systems to realize the full-process interaction and traceability of drug data.

[0031] Specifically, the external communication interface module includes a communication network interface, a local area network interface, and an internet interface. Before accessing the communication network interface, a hardware digital certificate is used to complete the identity and legality verification. The hardware digital certificate can use the Fudan Micro FM1230 chip to complete the certificate, key storage and verification. For example, the information communication network is accessed through a dedicated module, which is the ZY401 module, to realize real-time data interaction with the supervision system and improve the level of intelligence of supervision. The local area network interface is an RJ45 network port or a WiFi interface. It connects to the hospital's local area network through the RJ45 network port or WiFi interface to realize the connection with the hospital's information management system and anesthesia system, and to complete the synchronization of drug usage data. The Internet interface connects to the Internet via a 4G module. The 4G module uses a Hongtai Vision 790V2.9 module to achieve 4G LTE communication. It can insert a SIM card to realize information interaction with a remote server or cloud server, and complete remote operation and maintenance of the device and data cloud storage.

[0032] The cabinet 1 is equipped with a UPS power supply, which is electrically connected to the hardware board module, sensor module, electric lock module, identity verification module, human-machine interaction module, RFID drawer board 7 and motor drive board. It is used to provide stable power supply to each hardware module. When the 220V mains power fails, the power supply to the RFID drawer board 7 will also fail. The UPS power supply is a Dengfeng DF-518H50AC, which can provide 12A uninterrupted power supply for 8 hours.

[0033] The cabinet 1 is equipped with an audible and visual alarm module. When an identity verification failure, cabinet door opening timeout, mains power failure, network abnormality, excessive temperature and humidity, or abnormal vibration of cabinet 1 occurs, the audible and visual alarm module is immediately triggered. At the same time, the mainboard records and stores the abnormal information and uploads it to the corresponding server through the external communication interface module. The audible and visual alarm enables the medicine cabinet to have an alarm function, which can trigger the audible and visual alarm in a timely manner according to abnormal situations. For example, an alarm is triggered if there is an abnormality in the entry and exit time. The default time for entry is 5 minutes and the default time for exit is 30 seconds. The time duration can be flexibly configured through the intelligent cabinet software system. If the operation is not completed within the set time, the system triggers the audible and visual alarm.

[0034] During use, two operators complete dual authentication through the identity verification module. Each person can choose any two authentication methods, such as ID card and fingerprint, facial recognition and digital password. After successful verification, the electric lock unlocks and the system is successfully logged in. The administrator can perform system operations such as user permission configuration, time duration setting, and RF power adjustment through the touch screen 3. Operators can only perform drug entry and exit, recycling, and inventory operations. When medicines are received into the warehouse, the operator issues a receiving instruction via touchscreen 3. The corresponding electric drawer 12 is automatically opened by the motor drive board, and the grating anti-pinch sensor is in working condition. The barcode / QR code on the medicine bottle can be scanned by the barcode recognition module 5, or the RFID tag can be identified. The system automatically generates a receiving record, recording information such as the batch number, place of origin, volume, and name of the medicine. The receiving operation timer starts. If it is not completed within 5 minutes, the system triggers an audible and visual alarm. After receiving is completed, the operator closes the electric drawer 12. After the drawer is closed, the inventory count is automatically started. The RFID drawer plate 7 scans all holes 15 and identifies the RFID tag on the medicine bottle through time-division switching of the radio frequency link to complete accurate positioning and counting. The inventory results are displayed on touchscreen 3. When medicines are issued, the operator issues an issuance command via touchscreen 3, and the corresponding electric drawer 12 automatically opens. The issuance timer starts (default 30 seconds). After scanning the barcode / QR code on the medicine bottle or identifying the RFID tag, an issuance record is generated. If the operation is not completed within the time limit, an audible and visual alarm is triggered. After the issuance is completed, the electric drawer 12 is closed, and the system automatically completes the inventory of the remaining medicines.

[0035] When recycling medicines, the software defines a designated electric drawer 12 as a recycling unit. When recycling medicine bottles, the corresponding electric drawer 12 opens automatically, and the recycling record is completed by RFID or barcode / QR code identification. After closing the door, the number of recycled medicines is automatically counted.

[0036] Temperature and humidity sensors collect real-time temperature and humidity data inside cabinet 1, and vibration sensors detect whether cabinet 1 has been illegally pried open. If the temperature and humidity exceed the standard, cabinet 1 vibrates abnormally, or if there is a failure in identity recognition, power outage, or network abnormality, the sound and light alarm module will be triggered immediately, the mainboard will record the abnormal information, and upload it to the corresponding server through the external communication interface.

[0037] The motherboard enables data transmission within cabinet 1 via the RS485 interface. It also connects to the monitoring system via the information communication network interface, to the hospital's HIS / anesthesia system via the RJ45 network port / WIFI module, and to the cloud server via the 4G module, achieving real-time synchronization of drug data throughout the entire process. This allows for the tracking of drug entry, exit, use, and recycling information at any time.

[0038] In this embodiment, the scanning time for a single hole 15 of the RFID drawer panel 7 is 100ms, and the scanning time for all holes 15 is approximately 16s. The touch screen 3 displays the scanning status via a progress bar. The entry and exit timing of the electric drawer 12 can be adjusted according to the actual needs of the hospital. The tray adopts a perforated design, using different hole diameters to distinguish different specifications of medicines such as injections and powders. The hardware modules inside the cabinet 1 are cascaded via an RS485 interface to ensure the stability of data transmission. At the same time, a TF card storage unit is configured to achieve local data backup and prevent data loss.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
