[0027] Specifically,

[0028] The STM32 series microcontroller of the embodiment is connected using SPI interface. SPI interface generally includes four lines, which are master output / slave input (MOSI), master input / slave output (MISO), serial clock (SCK) and slave selection (SS). Among them, the SPI-MOSI pin of STM32 controller is connected to the data input pin of RFID identifier, and the SPI-MISO pin of STM32 is connected to the data output pin of RFID identifier. SPI-SCK pin is connected to the clock pin of RFID identifier, for synchronizing data transmission. In addition, a general I / O pin of STM32 is used as SPI-SS pin and connected to the chip selection pin of RFID identifier, and RFID identifier is selected for communication by pulling down the pin. When designing PCB (printed circuit board), it should be noted that the wiring length of these signal lines is as short as possible and equal, so as to reduce signal transmission delay and interference. At the same time, appropriate filtering capacitor, such as 0.1uF ceramic capacitor, should be added near the SPI interface pin to filter out high-frequency noise on the power supply.

[0029] The human body induction module uses wireless communication methods such as Bluetooth or Zigbee. STM32 uses the UART interface to connect with the Bluetooth module. Connect the STM32 UART-TX (transmit) pin to the Bluetooth module's receive pin, and the UART-RX (receive) pin to the Bluetooth module's transmit pin. At the same time, connect the Bluetooth module's power pin to the appropriate power supply, generally 3.3V or 5V (according to the requirements of the Bluetooth module), and add a decoupling capacitor such as a 10uF and 0.1uF capacitor in parallel near the power pin to stabilize the power supply.

[0030] For lighting LED strips, use the PWM (Pulse Width Modulation) output pin to control brightness, and the ordinary I / O pin to control the switch; for ultraviolet LED strips, use the ordinary I / O pin to control the switch. The driving circuit of the lighting LED strip generally includes a current-limiting resistor. Connect the STM32 PWM output pin to the control input of the LED strip driving circuit, and control the brightness by adjusting the duty cycle of the PWM signal. For the switch control pin, connect it to the enable pin of the driving circuit. The control I / O pin of the ultraviolet LED strip is connected to the switch control pin of its driving circuit. When connecting the power supply of the LED strip, pay attention to the rated voltage and current of the strip. The lighting LED strip generally uses a 12V or 24V power supply, and the ultraviolet LED strip may have different voltage requirements according to its power. And add appropriate fuses on the power line to prevent overcurrent damage to the circuit.

[0031] For LCD touch screens, connect through the SPI interface or parallel interface. If it is an SPI interface, the connection method is similar to the connection of SPI and RFID identifier, but consider the communication protocol requirements of the LCD touch screen. If it is a parallel interface, more I / O pins are required.

[0032] For the SPI interface, in addition to the connection of the MOSI, MISO, SCK and SS pins, some control pins may also need to be connected, such as the reset pin (RST), data / command selection pin (DC), etc. These pins are connected to the corresponding I / O pins of the STM32 according to the specific model and data manual requirements of the LCD touch screen. When connecting a parallel interface, according to the data bit width of the LCD touch screen (such as 8 bits or 16 bits), connect multiple I / O pins of the STM32 to the data pins of the touch screen, and at the same time connect control pins such as the read-write control pin (WR), chip select pin (CS), etc. And add a pull-up resistor near the interface pin, generally 4.7kΩ - 10kΩ, to ensure the stability of the signal.

[0033] The connection with the display screen, for LED display screen, generally through simple I / O pin connection, according to the control mode of display screen, may need to use shift register to expand I / O function. Connect the I / O pin of STM32 to the segment selection pin and bit selection pin of the display screen. For multi-bit digital tube display screen, you can use 74HC595 and other shift registers to expand I / O pin, connect the SPI interface or several I / O pins of STM32 to the input pin of shift register, and control the display screen through the output pin of shift register. During the connection process, pay attention to the level matching of the signal. Generally, the driving voltage of LED display screen is 5V, while the I / O pin output of STM32 is 3.3V, which may need to add level conversion circuit, such as using 74LVC245 chip for level conversion.

[0034] The IC card reader is connected with the IC card reader using UART interface. Connect the UART-TX pin of STM32 to the receiving pin of IC card reader, and the UART-RX pin to the sending pin of card reader. At the same time, connect the power pin of card reader to the appropriate power supply, and add decoupling capacitor.

[0035] The fingerprint recognizer is connected with the fingerprint recognizer through USB interface. Connect the USB-D+ and USB-D- pins of STM32 to the USB data pins of fingerprint recognizer. The power supply of fingerprint recognizer is generally 3.3V or 5V. According to the requirements of the recognizer, add decoupling capacitor. And when connecting USB interface, pay attention to the support of USB protocol, you need to configure the corresponding USB driver in STM32.

[0036] The face recognition camera is connected with the face recognition camera through CSI (Camera Serial Interface). For CSI interface, connect the CSI interface pin of STM32 to the CSI interface pin of face recognition camera according to the data manual of camera. During the connection process, pay attention to the power supply of camera. Generally, there are many power supply requirements, such as 3.3V, 1.8V, etc. Provide stable power supply respectively, and add decoupling capacitor.

[0037] The connection with the temperature sensor is connected through the I2C interface. The I2C interface includes two lines, namely the serial data line (SDA) and the serial clock line (SCLK). Connect the I2C-SDA pin of the STM32 to the SDA pin of the temperature sensor, and the I2C-SCLK pin to the SCLK pin of the temperature sensor. When connecting, add a pull-up resistor of about 4.7kΩ on the SDA and SCLK pins to ensure normal transmission of signals. At the same time, the power supply pin of the temperature sensor is connected to the appropriate power supply, and a decoupling capacitor such as a 0.1uF ceramic capacitor is added to stabilize the power supply.

[0038] The electromagnetic lock is connected through a common I / O pin. Connect an I / O pin of the STM32 to the control end of the electromagnetic lock. The electromagnetic lock generally has a drive circuit that energizes (or de-energizes) the electromagnetic lock when the I / O pin outputs a high level (or low level, depending on the drive requirements of the electromagnetic lock). When connecting the power supply of the electromagnetic lock, pay attention to the rated voltage and current of the electromagnetic lock, and generally the working voltage of the electromagnetic lock is 12V or 24V, and add a suitable fuse on the power supply line to prevent overcurrent damage to the circuit. At the same time, in order to avoid electromagnetic interference, the power supply line and control signal line of the electromagnetic lock should be kept a certain distance from other sensitive signals (such as sensor signal lines).

[0039] Example 2

[0040] The intelligent medical consumable storage management system of this embodiment is mainly composed of an intelligent cabinet body, a cabinet door and various electronic components inside. The cabinet body is made of a solid and durable metal material that is resistant to rust, ensuring long-term stable use in a hospital environment. Its structure is designed in a multi-layer shelf form, making it easy to store different types of medical consumables. The cabinet door is double-locked by an electromagnetic lock and a mechanical lock to ensure the safety of the cabinet and prevent unauthorized opening.

[0041] The controller of the embodiment, as the core control unit of the entire system, selects a high-performance embedded microcontroller with powerful data processing capability and stable operation performance. It is responsible for receiving and processing data from various sensors, identifiers, and human-computer interaction devices, and controlling various operations of the intelligent cabinet according to the preset logic rules, such as the opening and closing of the cabinet door, the start of the lighting and disinfection functions, etc. The controller is connected with RFID identifier, temperature sensor, electromagnetic lock and other devices through wired communication line, to ensure the rapid and stable data transmission; at the same time, through the wireless communication module (such as Wi-Fi or Bluetooth), it interacts with the background server to realize remote monitoring and management. Among them, the controller selects the STM32 series microcontroller of ST. STM32 series has rich peripheral interfaces, including but not limited to SPI interface (used to connect RFID identifier, etc.), UART interface (used to communicate with background server, etc.), I2C interface (can connect temperature sensor, etc.). Moreover, it has fast operation speed, which can quickly process the signals from the human body sensing module to realize the timely response of the lighting LED lamp strip. At the same time, its internal timer and interrupt system can be well used to control the disinfection time setting of the ultraviolet LED lamp strip and the control of the electromagnetic lock, etc.

[0042] The RFID identifier of the embodiment adopts high-sensitivity ultra-high frequency RFID identification technology, with a working frequency of 902-928MHz band, which can quickly and accurately identify medical consumables with RFID tags. Through the 902-928MHz antenna, it is connected with the controller. When the consumables enter or exit the intelligent cabinet, the RFID identifier can read the consumable tag information in real time and transmit the data to the controller, so as to realize the accurate management of consumable inventory and the automatic recording of taking and returning. Among them, RFID identifiers are installed between the layers of shelves or below each layer of shelves. When a consumable is taken out from the middle position of the shelf, the RFID identifier below the shelf can read the tag information through the gap of the shelf, so as to realize the dynamic and effective monitoring of the consumables on each layer of shelf.

[0043] The human body sensing module of the embodiment: selects a 60GHz human body presence sensor, which is installed at the top of the intelligent cabinet. The sensor uses millimeter wave technology to accurately detect the approach and departure of the human body. When someone approaches the intelligent cabinet, the sensor will immediately send a signal to the controller through wireless connection. After the controller receives the signal, it will control the lighting LED lamp strip to turn on according to the preset program, which is convenient for the operator to operate; when the personnel leave for a period of time (the delay time can be set), the lighting lamp strip automatically turns off to save energy.

[0044] The lighting LED lamp strip and the ultraviolet LED lamp strip of the embodiment, the lighting LED lamp strip adopts high-brightness and low-power white LED lamp beads to provide sufficient light, which facilitates the operator to find and take the consumables in the cabinet. The ultraviolet LED lamp strip selects ultraviolet lamp beads with a wavelength of 254 nm, which has high sterilization and disinfection capacity. The two are arranged side by side and staggered in the cabinet body of the intelligent cabinet, and are independently controlled by the controller. Under normal circumstances, the lighting lamp strip is switched according to the signal of the human body sensing module; and during the set disinfection period, from 2 to 4 o'clock in the morning every day, when the hospital operation activity is less, the controller automatically closes the lighting lamp strip and starts the ultraviolet LED lamp strip for disinfection operation. The disinfection time can be set according to the actual demand to ensure the sterile state of the cabinet environment and reduce the risk of microbial pollution of medical consumables. The controller is connected with the lighting LED lamp strip and the ultraviolet LED lamp strip through control lines. These control lines can be ordinary wires, which establish a connection between the output port of the controller and the driving circuit of the LED lamp strip. For the lighting LED lamp strip, the controller realizes the switching and brightness adjustment of the lamp strip through a control signal. For the ultraviolet LED lamp strip, the control signal is also used to control its opening and closing. During normal operation, when the human body approaches the cabinet body, the controller outputs a high-level signal to make the driving circuit of the lighting LED lamp strip work to light up the lamp strip; during the disinfection period, the controller outputs a signal to turn on the driving circuit of the ultraviolet LED lamp strip for disinfection

[0045] The LCD touch screen of the embodiment, the operator can perform various operations through the touch screen, query the consumable inventory information, view the records of taking and returning, and set the parameters of the intelligent cabinet, such as disinfection time, temperature threshold, etc. The touch screen adopts a high-resolution and high-sensitivity liquid crystal display screen, has an intuitive and friendly user interface, and is convenient for medical staff to quickly operate.

[0046] The display screen is used to display some key information, such as the current state of the intelligent cabinet (on / off, disinfecting, fault prompt, etc.), real-time time, temperature data, etc. The display screen adopts an LED display screen, which has good visibility and can clearly see the display content even at a long distance.

[0047] The IC card reader, the medical staff uses the IC card uniformly issued by the hospital for identity verification, the card reader adopts advanced radio frequency identification technology, can quickly read the information in the IC card, and transmits it to the controller, compares it with the personnel information stored in the background server, and confirms the identity, and the controller controls the opening of the cabinet door and the related operation permission according to the preset permission.

[0048] Fingerprint identifier: As an additional authentication method, the fingerprint identifier uses high-precision optical fingerprint recognition technology to quickly and accurately identify the fingerprint information of medical staff. Medical staff only need to place their fingers on the identifier to complete the authentication, improving the security and convenience of authentication.

[0049] Face recognition camera: Using advanced face recognition algorithms and high-definition cameras, the face recognition camera identifies and verifies the facial features of the operator. In low light or when the operator wears a mask, it still maintains high recognition accuracy. The face recognition camera is connected to the controller and transmits the collected face image to the controller for processing and comparison, ensuring that only authorized personnel can operate the intelligent cabinet.

[0050] Temperature sensor: The temperature sensor in this embodiment uses a high-precision thermistor temperature sensor installed inside the intelligent cabinet body to monitor the temperature changes inside the cabinet in real time. When the temperature exceeds the preset temperature range (e.g. 15℃ - 25℃), the controller will immediately issue an alarm signal and send temperature anomaly information to the background server through wireless connection, reminding the management personnel to take timely measures (such as checking the air conditioning system or adjusting the placement position of the intelligent cabinet), ensuring that medical consumables are stored in a suitable temperature environment, and ensuring their quality and performance are not affected.

[0051] Electromagnetic lock and mechanical lock: The top and bottom of the intelligent cabinet body are respectively equipped with electromagnetic locks, and the corresponding positions of the cabinet door are also equipped with electromagnetic locks. The controller controls the power-on and power-off of the electromagnetic lock to achieve quick opening and closing of the cabinet door. In case of electromagnetic lock failure or power failure, the mechanical lock installed in the middle of the cabinet door can be used as a backup unlocking method. The mechanical lock uses a durable lock core and lock body to ensure the safety of the cabinet in emergency situations, while also meeting the strict safety requirements of hospitals for medical equipment. The controller and electromagnetic lock are connected through a control signal line. When the authentication is passed or other conditions for opening the door are met, the controller outputs a high or low level signal to control the power-on and power-off of the electromagnetic lock. During normal door opening operation, the controller outputs a signal to energize the electromagnetic lock coil, generating a magnetic force to open the electromagnetic lock; after closing the door, the controller outputs a signal to de-energize the electromagnetic lock, locking the cabinet door. The mechanical lock is not electrically connected to the controller, and it serves as an independent backup unlocking method in emergency situations (such as electromagnetic lock failure or power failure).

[0052] The shelf of the present embodiment is provided with a plurality of layers of shelves in the cabinet body of the intelligent cabinet, and adopts an adjustable shelf design, which facilitates flexible adjustment according to the size and quantity of different types of medical consumables. A plurality of partitions are arranged on each shelf body of the shelf, and a clamping groove is arranged at the bottom of the shelf body. The partitions are made of plastic material and have certain flexibility and wear resistance. The consumables can be separated as needed by clamping the partitions in the clamping groove, preventing mutual collision and extrusion between the consumables, and facilitating classified management and quick search and use of the consumables.

[0053] The present embodiment also includes a software module, and an embedded software system running on the controller is responsible for the logical control and data processing of the entire intelligent medical consumable storage management system. It includes the following main functional modules:

[0054] Identity verification module: processes and compares the received IC card information, fingerprint information and face image information, and verifies the personnel information stored in the background server to confirm the identity and authority of the operator.

At the same time, it can generate inventory reports to facilitate inventory checking and procurement planning.

[0056] Disinfection control module: automatically controls the opening and closing of the ultraviolet LED light strip according to the preset disinfection time and conditions, records disinfection logs including disinfection time, duration, disinfection effect, etc. for traceability and management.

[0057] Data communication module: responsible for data interaction with the background server, uploads the running state information of the intelligent cabinet (such as cabinet door opening and closing records, temperature data, inventory changes, etc.) to the server, and receives the instruction and parameter setting information (such as personnel authority update, disinfection time adjustment, etc.) issued by the server, ensuring seamless integration of the intelligent cabinet with the hospital information management system.

[0058] Alarm module: when the system has abnormal conditions such as temperature abnormalities, electromagnetic lock failures, RFID identification abnormalities, etc., it immediately sends out an audible and visual alarm signal and sends the alarm information to the background server to notify the management personnel to handle it in time, ensuring the safety of medical consumables and the normal operation of the system.

[0059] Embodiment 2

[0060] After the medical consumables purchased are put into the warehouse of the hospital, the staff first stick a unique RFID tag on each single consumable, and the detailed information of the consumable is recorded in the tag, including name, specification, model, manufacturer, production date, expiration date, batch number, etc. Then, the staff put these tagged consumables into the intelligent cabinet in batches. When the consumables pass through the entrance of the cabinet body, the RFID identifier automatically reads the tag information and transmits the data to the controller. The controller uploads these information to the background server to complete the warehousing operation, and updates the inventory quantity and location information. On the background server, the inventory situation of the consumables in each intelligent cabinet can be clearly seen.

[0061] Surgical consumable taking

[0062] Before the operation, the lead surgeon or operating room nurse comes to the intelligent cabinet and verifies the identity through an IC card, fingerprint, or face recognition. After the identity verification is passed, the LCD touch screen will display the taking permission of the person and the list of consumables that can be taken. The operator selects the consumables to be taken according to the operation needs on the touch screen. After the controller receives the instruction, it controls the electromagnetic lock at the corresponding position to open, and the lighting LED light belt is turned on to facilitate the operator to take out the consumables. When the consumables are taken out, the RFID identifier reads the tag information again and sends the taking record to the controller. The controller updates the inventory information and uploads the taking information to the background server, realizing the automatic recording of the taking process and the real-time updating of the inventory.

[0063] Surgical consumable return

[0064] After the operation, for the unused medical consumables, the operator brings them back to the front of the intelligent cabinet and opens the cabinet door after identity verification. The RFID identifier reads the tag information of the returned consumables, the controller confirms the return information and updates the inventory quantity, and uploads the return record to the background server. If the quantity or type of returned consumables does not match the taking record, the system will automatically issue an alarm to prompt the operator to check and correct, ensuring the accuracy of the inventory data.

[0065] Daily disinfection management

[0066] At 2 a.m. every day, the controller of the smart cabinet automatically starts the disinfection program. First, the controller turns off the lighting LED strip, then turns on the ultraviolet LED strip, and starts disinfection work in the cabinet. During disinfection, the temperature sensor continuously monitors the temperature in the cabinet to ensure the stability of the disinfection environment. The disinfection time is set to 60 minutes. After disinfection, the controller automatically turns off the ultraviolet LED strip and records the disinfection log, including the start time, end time, and whether it is completed normally. The management personnel can check the disinfection record and status of the smart cabinet at any time through the background server to ensure the effective implementation of disinfection work, reduce the risk of medical consumables being contaminated, and ensure medical safety.

[0067] Abnormal situation processing

[0068] Due to a temporary failure of the hospital power system, the electromagnetic lock of a smart cabinet is accidentally unlocked. At this time, the controller of the smart cabinet immediately detects the abnormal state of the electromagnetic lock and sends an alarm message to the background server through wireless connection. At the same time, the display screen on the cabinet door displays the prompt information "electromagnetic lock failure, please contact the management personnel" and sends an audible and visual alarm signal. After receiving the alarm, the management personnel quickly arrive at the scene, temporarily lock the cabinet door with a mechanical lock, and check and repair the electromagnetic lock to ensure the safety of the smart cabinet.
