[0029] like Figure 1 As shown, the utility model discloses a medical information management system, including a positioning base station 1, a positioning tag 2, a host computer 3, a communication module 4 and a display device. The positioning base station 1 is used to receive the position signal of the positioning tag 2. The positioning base station 1 is installed on the ceiling, and the positioning tag 2 is installed on the patient's wristband, medical staff badge or medical equipment. The positioning base station 1 communicates with the host computer 3 through the communication module 4. The display device displays the current distribution of personnel and medical equipment in the ICU, displays alarm information on the screen, and provides the best path from the current location to the target location.

[0030] like Figure 2 As shown, the positioning base station 1 and the positioning tag 2 both include a UWB chip and a microprocessor. The microprocessor U1 is STM32F103C8T6. Figure 3 As shown, the UWB chip U2 is a DWM1000 module, the 12th pin of the microprocessor U1 is connected to the 27th pin of the UWB chip U2, the 13th pin of the microprocessor U1 is connected to the 45th pin of the UWB chip U2, the 14th pin of the microprocessor U1 is connected to the 24th pin of the UWB chip U2, the 15th pin of the microprocessor U1 is connected to the 41st pin of the UWB chip U2, the 16th pin of the microprocessor U1 is connected to the 40th pin of the UWB chip U2, and the 17th pin of the microprocessor U1 is connected to the 39th pin of the UWB chip U2.

[0031] The DWM1000 module offers three data transmission rates, up to 6.8Mbps. The DWM1000 module requires a voltage between 2.8 and 3.6V to operate, drawing only 3.5mA of current during normal operation and 100nA in sleep mode. Therefore, the DWM1000 module offers the advantage of low power consumption. This effectively ensures low-power operation of the system, eliminating the need for a dedicated power supply for the positioning system. Microprocessor U1's PA9 and PA10 also serve as serial interface 1 for code debugging. PB1 is connected to an LED to indicate system operating status.

[0032] First, a positioning tag 2 containing a UWB chip and a microprocessor (such as the STM32F103C8T6) is installed on the patient's wristband, the medical staff's badge, or the medical device that needs to be tracked. These positioning tags 2 periodically transmit signals including their unique identifiers.

[0033] The positioning base station 1 is responsible for receiving the location signal from the positioning tag 2. By calculating the signal arrival time difference (TimeDifference of Arrival, TDoA) or directly measuring the signal flight time (Time of Flight, ToF), the positioning base station 1 can accurately determine the relative position of each positioning tag 2. The received location data is preliminarily processed by the microprocessor on the positioning base station 2 and sent to the host computer 3 through the communication module 4. The host computer is used to further analyze and process the information collected from each positioning base station 1. The host computer will transmit the processed personnel and equipment distribution to a display device, such as an LCD display, LED display, tablet computer or smart phone. These devices will not only display the current layout of the ICU and the specific location of each person and equipment, but also update the alarm information in real time.

[0034] The host computer will maintain a digital map of the ICU, which contains information about fixed structures such as room layouts, corridors, and doors. The map will also be updated based on actual conditions, such as temporary obstacles or the location of newly added equipment. Once the starting point (current location) and the end point (target location) are determined, the host computer will use a path planning algorithm to calculate the optimal path. The calculated optimal path is transmitted to a display device such as an LCD display, LED display, tablet computer, or smart phone through the communication module 4. The display device will show the current layout of the ICU and the marked path on the screen so that the user can intuitively see how to get from the current location to the target location.

[0035] The positioning base station 1 also includes a temperature and humidity sensor circuit, such as Figure 4 As shown, the temperature and humidity sensor circuit includes humidity sensor U3 and resistor R6. Pin 2 of humidity sensor U3 is connected to pin 43 of microprocessor U1. The DHT11 module, an integrated temperature and humidity sensor, is used. This module is known for its high accuracy, low cost, small size, and simple interface. A 3kΩ pull-up resistor is incorporated into the circuit design to ensure signal stability. A 1μF capacitor C9 is also included for filtering before the DHT11 sensor receives power, effectively reducing the potential impact of power supply ripple on sensor performance.

[0036] The positioning base station 1 also includes an air quality sensor circuit, such as Figure 5As shown, the air quality sensor circuit includes an air quality sensor U4 and a capacitor C114. Capacitor C114 is connected between pins 1 and 2 of the air quality sensor U4. Pin 3 of the air quality sensor U4 is connected to pin 32 of the microprocessor U1, and pin 6 of the air quality sensor U4 is connected to pin 33 of the microprocessor U1. The air quality sensor uses an SGP30, which can simultaneously collect CO2 and TVOC concentrations using the chip's integrated AD / DA converter. The collected data is processed to obtain the corresponding data.

[0037] The positioning base station 1 also includes a light sensor circuit, such as Figure 6 As shown, the light sensor circuit includes light sensor U5. Pin 2 of light sensor U5 is connected to pin 45 of microprocessor U1, and pin 3 of light sensor U5 is connected to pin 46 of microprocessor U1. The light sensor uses a GY-30 light sensor to detect the light intensity in the classroom. This sensor uses the I2C communication protocol and has a built-in A / D converter. Therefore, the GY-30 light sensor directly outputs a digital signal, eliminating the need for A / D conversion via the STM32. The light sensor has a supply voltage of 3 to 5V and an illuminance range of 0 to 65535 lx. The STM32 can obtain the light intensity value measured by the sensor.

[0038] like Figure 7 As shown, communication module 4 includes a WiFi wireless transmission module U6. Pin 20 of WiFi wireless transmission module U6 is connected to pin 22 of microprocessor U1. Pin 21 of WiFi wireless transmission module U6 is connected to pin 21 of microprocessor U1. Pin 22 of WiFi wireless transmission module U6 is connected to pin 18 of microprocessor U1. Wireless transmission uses the ESP8266 WiFi wireless transmission module, which integrates the WiFi transmission protocol. WiFi communication can be achieved by sending AT commands via the serial port through the transparent transmission module.

[0039] Display devices include LCD monitors, LED screens, tablet computers, and smartphones. Medical workers can use these devices to monitor the distribution of personnel and medical equipment within the ICU, as well as alarm information (primarily triggering alarms when temperature, humidity, light, and air quality exceed thresholds), and the optimal route from their current location to their destination.

[0040] The positioning tags are embedded with a UWB chip (DWM1000 module) and a microprocessor (STM32F103C8T6). These tags periodically transmit location signals containing a unique identifier. The positioning base station is also equipped with a UWB chip and microprocessor. After receiving the signals from the positioning tags, the positioning base station determines the precise location of each tag by calculating the signal's time difference of arrival (TDoA) or directly measuring the signal's time of flight (ToF). The received location data is initially processed by the microprocessor on the positioning base station, including filtering and correction steps to improve positioning accuracy. This processed data is then transmitted to a host computer via a communication module (such as an ESP8266 WiFi wireless transmission module). The WiFi wireless transmission module ensures fast and stable data transmission. The host computer receives data from each positioning base station and performs further analysis and processing. The host computer maintains a digital map of the ICU. This map includes information on fixed structures such as room layouts, corridors, and doors, and can be updated in real time to reflect temporary obstacles or the location of newly added equipment.

[0041] The positioning base station also integrates a temperature and humidity sensor (DHT11), an air quality sensor (SGP30), and a light sensor (GY-30). These sensors continuously monitor environmental parameters in the ICU, such as temperature, humidity, CO2 concentration, TVOC concentration, and light intensity. When environmental parameters exceed the preset threshold, the system triggers an alarm and sends relevant information to the host computer. The processed personnel and equipment distribution, environmental monitoring data, and path navigation information are sent to a display device (such as an LCD display, LED display, tablet computer, or smartphone) through a communication module. The display device will not only display the current layout of the ICU and the specific location of each person and equipment, but will also update the alarm information in real time so that medical staff can take timely action. The display device will also show the path from the current location to the target location to help medical staff navigate quickly.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention.
