Description

Technical Field

[0001] This application relates to the field of Internet of Things (IoT) technology, and in particular to an intelligent vehicle-mounted medical emergency kit management system. Background Technology

[0002] Car first-aid kits are typically kept in vehicles as standard equipment, usually in locations such as the trunk, glove box, or under the seats. When the vehicle is in motion, occupants can easily access these supplies. However, in emergency situations, existing car first-aid kit solutions have some shortcomings.

[0003] In terms of ease of access, after an accident, a vehicle may be deformed, lose power, or roll over due to the collision. The interior environment may be dark or filled with smoke, and occupants may have limited mobility due to injury or panic. Traditional first-aid kits are fixed in specific storage spaces, making it difficult for occupants or rescuers to quickly and accurately find and retrieve them, which may delay rescue efforts.

[0004] Regarding proactive guidance, existing solutions are mostly passive response mechanisms, such as calling for help by pressing a button or relying on post-accident personnel dispatch for rescue. These solutions cannot proactively provide occupants with directions to the location of first-aid kits at the moment of an accident, helping them to quickly access emergency supplies.

[0005] Regarding situational awareness, occupants typically cannot know in advance whether the supplies in the first-aid kit are complete or whether the medications are expired before retrieving them. In an emergency, if the retrieved first-aid kit contains expired medications or missing equipment, it will affect the effectiveness of the rescue.

[0006] Some related technologies attempt to locate first aid kits via physical grab handles or Bluetooth connections from mobile phones. Physical grab handle solutions require multiple handles within the vehicle, resulting in complex wiring, and their usability may be affected by vehicle deformation after an accident. Bluetooth solutions rely on the user's phone communicating with the first aid kit, but in an accident, the phone may be damaged, lose power, or become detached from the occupant, raising concerns about reliability.

[0007] Therefore, how to provide a system that can quickly and intuitively guide passengers to find and retrieve the vehicle first aid kit in an emergency has become a technical problem that needs to be solved. Summary of the Invention

[0008] The purpose of this invention is to provide an intelligent vehicle-mounted medical first aid kit management system to solve the problem in the prior art that, in emergency situations, the retrieval of vehicle-mounted first aid kits is limited by ambient light and vehicle status, making it difficult to quickly guide passengers to find and retrieve them.

[0009] This invention provides the following solution:

[0013] The in-vehicle positioning network includes multiple pre-installed positioning base stations in the vehicle. The positioning base stations cooperate with the positioning beacon to determine the first location information of the smart first aid kit in the vehicle coordinate system.

[0014] The occupant positioning unit is used to acquire the second position information of the occupant in the vehicle coordinate system.

[0015] In-vehicle sensors are used to detect vehicle collision events and generate collision detection signals;

[0016] A backup power module is used to provide power to the vehicle control module and the smart first aid kit when the vehicle's main power is interrupted;

[0017] The vehicle control module is configured as follows:

[0018] Receive a trigger signal, wherein the trigger signal is a voice trigger signal generated by the voice recognition unit in response to recognizing a preset emergency voice command, and / or a collision trigger signal generated by the logic processing unit based on the collision detection signal;

[0019] In response to receiving the trigger signal, the positioning beacon on the smart first aid kit is activated through the wireless communication module, and the first location information is obtained using the in-vehicle positioning network;

[0020] Based on the first location information and the second location information, guidance information is generated, which includes a description of the location and distance of the smart first aid kit relative to the occupant.

[0021] The system controls the display unit to display the guidance information, controls the voice module to output voice navigation corresponding to the guidance information, and controls the sound and light indicator on the smart first aid kit to emit an indicator signal to guide the occupant to retrieve the first aid kit.

[0022] Optionally, the occupant positioning unit includes seat pressure sensors respectively installed under each seat, and pre-stored coordinate values ​​of each seat in the vehicle coordinate system; the occupant positioning unit determines the seat where the occupant is located through the triggered seat pressure sensors, and uses the pre-stored coordinate value corresponding to the seat as the second position information.

[0023] Optionally, the in-vehicle sensors include at least one of an acceleration sensor and an airbag sensor; the collision detection signal includes at least one of an acceleration signal and an airbag deployment signal.

[0024] Optionally, the vehicle control module is further configured to: obtain the status information of the smart first aid kit through the wireless communication module before or during the output of the guidance information, and control the voice module to broadcast the status information; the status information includes at least one of the following: in-place status, battery level, and medicine expiration date.

[0025] Optionally, the drug input detection unit includes an input device and a memory; the input device is used to receive the drug name and corresponding expiration information entered by the user, and the memory is used to store the drug name and corresponding expiration information; the vehicle control module is also configured to determine whether the drug is expired or about to expire based on the expiration information and the current time, and when the drug is determined to be expired or about to expire, control the voice module to output corresponding prompt information in the voice navigation.

[0026] Optionally, the positioning beacon is an ultra-wideband (UWB) beacon, the positioning base station is a UWB base station, the UWB base station is installed at known coordinate positions inside the carriage, and communicates with the UWB beacon through time difference of arrival or time of flight ranging to calculate the first position information; the sound and light indication device includes an LED light strip and a buzzer; the wireless communication module is a Bluetooth module.

[0027] Optionally, the display unit is specifically used to display a schematic diagram of the vehicle interior and to mark the location of the smart first aid kit on the schematic diagram with dynamic icons.

[0028] Optionally, it also includes a vehicle component actuator connected to the vehicle control module, the vehicle component actuator including a trunk locking mechanism and / or an electric strut; the vehicle control module is further configured to send a control signal to the vehicle component actuator when generating the guidance information, so as to automatically unlock the trunk and / or open the trunk to a preset gap.

[0029] Optionally, the vehicle control module is further configured to execute a drug management process, which includes:

[0030] After the vehicle starts, the expiration date and location information of the medicines in the smart first aid kit are obtained through the wireless communication module.

[0031] Based on the expiration date information and the current time, determine whether the drug has expired or is about to expire, and / or based on the location information, determine whether the drug is missing;

[0032] When it is determined that a drug is expired, nearing its expiration date, or is missing, the display unit is controlled to display a reminder message, and / or the voice module is controlled to output a reminder voice message.

[0033] Optionally, the backup power module is configured to automatically switch to powering the units related to the guidance function in the vehicle control module, the positioning beacon and audio-visual indicator of the smart first aid kit, and the in-vehicle positioning network when an interruption of the vehicle's main power is detected.

[0034] The above solution achieves the following beneficial technical effects: In terms of response speed, the system supports triggering via voice interaction; after the user speaks a preset emergency command, the system can initiate the guided process. Simultaneously, the system can also be linked with vehicle collision sensors, automatically triggering upon detecting a severe collision. This dual-trigger mechanism does not rely on physical buttons or screen operation, helping to shorten the system's response time.

[0035] In terms of guidance methods, the system combines dynamic illustrations on the vehicle's infotainment screen, voice navigation, and audio-visual indicators on the first aid kit itself. The screen can display a diagram of the vehicle's interior and mark the location of the first aid kit, the voice can announce the location information, and the indicator lights and buzzer on the first aid kit itself can emit warning signals. This multimodal guidance method can still provide effective guidance for occupants in dimly lit or poorly lit environments.

[0036] In terms of status awareness, the system can obtain the status information of the first aid kit before or during guidance, including its availability, battery level, and medication expiration dates, and inform the occupants via voice. In daily use, the system can also monitor the expiration dates and availability of medications. When expired, near-expiration, or missing medications are detected, the system will remind the user via sound and light to replenish or replace them, ensuring the first aid kit remains usable.

[0037] In terms of reliability, the system integrates a backup power module, which can switch to the backup power supply to power the core guidance functions when the vehicle's main power is interrupted due to an accident. The voice recognition unit can operate offline and does not rely on a network connection, helping to maintain the system's basic functions under extreme conditions.

[0038] In terms of overall effectiveness, through the synergy of the above functions, this invention helps to shorten the time from the occurrence of an emergency to the occupants obtaining first aid supplies, providing more timely support for occupants to carry out self-rescue and mutual rescue.

[0039] Figure 1 This is a schematic diagram of the intelligent vehicle-mounted medical emergency kit management system according to an embodiment of the present invention.

[0040] Figure 2This is a schematic diagram of the vehicle control module according to an embodiment of the present invention. Detailed Implementation

[0041] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of 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.

[0042] In the description of this invention, it should be understood that the terms "front," "rear," "axial," etc., indicating orientation or positional relationships are based on the orientation that the operator is accustomed to facing during testing, and are only for the convenience and simplification of description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "installation," "connection," and "fixing" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection, unless otherwise explicitly specified and limited.

[0043] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0044] During vehicle use, in-vehicle first-aid kits are typically stored in locations such as the trunk, glove box, or under the seats. However, in real-world emergency scenarios, such as collisions, rollovers, or sudden illnesses of occupants, the vehicle interior may be dark or filled with smoke. Occupants may also be injured or panicked, making it difficult to quickly and accurately locate and retrieve the first-aid kit. Existing in-vehicle first-aid kit solutions are mostly passively stored, lacking proactive guidance and status awareness capabilities, which can easily delay the golden time for self-rescue and mutual aid.

[0045] While some related technologies offer solutions for locating first-aid kits via physical handles or Bluetooth from mobile phones, physical handles involve complex wiring and lack status feedback. Furthermore, mobile phones may be damaged, lose power, or become detached during an accident, resulting in poor reliability. Therefore, achieving rapid response and intuitive guidance for first-aid kits without complex operations and without being severely limited by ambient light or vehicle status has become a pressing issue.

[0046] In view of this, in order to solve at least one of the above technical problems, the present invention proposes a vehicle-mounted first aid kit guidance system, which significantly shortens the time from the occurrence of an emergency to the acquisition of first aid supplies and improves the survival probability of occupants through voice interaction, multimodal fusion guidance and linkage with vehicle status mechanism.

[0047] The present invention will now be described in detail with reference to the embodiments and accompanying drawings.

[0048] This invention provides an intelligent vehicle-mounted first-aid kit management system, such as... Figure 1 As shown, the system includes:

[0049] The vehicle control module, intelligent first aid kit, in-vehicle positioning network, occupant positioning unit, in-vehicle sensors, backup power module, and vehicle component actuators.

[0050] In this embodiment of the invention, the vehicle control module includes a voice recognition unit, a logic processing unit, a display unit, and a voice module. The voice recognition unit monitors in-vehicle voice prompts in real time and recognizes preset emergency voice commands. These preset emergency voice commands include, but are not limited to, natural language expressions such as "Help," "Open the first aid kit," and "I need a first aid kit." The logic processing unit is responsible for functions such as trigger judgment, location calculation, guidance information generation, and status management. The display unit can be the vehicle's central control screen, used to display the guidance interface and reminder information. The voice module is used to output voice navigation and status announcements.

[0051] In this embodiment of the invention, the intelligent first aid kit is a container for storing first aid medicines and equipment. It incorporates a wireless communication module, a positioning beacon, an audible and visual indicator, a medicine input detection unit, and an in-situ sensor. The wireless communication module preferably uses Bluetooth for data interaction with the vehicle's infotainment system. The positioning beacon preferably uses an ultra-wideband (UWB) beacon, enabling real-time positioning with centimeter-level accuracy in conjunction with the in-vehicle positioning network. The audible and visual indicator includes an LED light strip and a buzzer, used to emit highly visible flashing light and a penetrating audible alert in emergencies to guide occupants to the first aid kit.

[0052] In this embodiment of the invention, a medication entry detection unit is used to record medication information when a user places medication into a first-aid kit. The medication entry detection unit includes an input device and a memory. The input device can be a touch panel or physical button on the first-aid kit, or a vehicle-mounted touchscreen or user's mobile phone connected to the first-aid kit via Bluetooth. When placing medication, the user enters the medication name and corresponding expiration date information through the input device, and the memory associates and stores this information with the corresponding medication slot. An in-situ sensor is used to detect whether medication is placed in each medication slot; this can be implemented using an infrared photocell sensor or a microswitch. When medication is placed in a slot, the sensor is triggered to generate an in-situ signal.

[0053] In this embodiment of the invention, the in-vehicle positioning network includes multiple positioning base stations, preferably UWB base stations, pre-installed at fixed locations inside the vehicle. These UWB base stations are installed at known coordinate locations within the vehicle compartment, for example, on the center console, the B-pillars on both sides, the top of the trunk, and under the rear seats. The three-dimensional coordinates of each UWB base station are pre-calibrated and stored in the logic processing unit. When positioning is required, the UWB beacon on the smart first aid kit broadcasts a positioning signal. Each UWB base station receives the signal and records the reception timestamp. The logic processing unit calculates the distance from the UWB beacon to each base station based on the time difference of arrival or time-of-flight ranging method, and then calculates the first position information of the smart first aid kit in the vehicle coordinate system.

[0054] In this embodiment of the invention, the occupant positioning unit is used to acquire the second position information of the occupant in the vehicle coordinate system. The occupant positioning unit includes seat pressure sensors respectively installed under each seat, and the coordinate values ​​of each seat in the vehicle coordinate system pre-stored in the logic processing unit. When an occupant sits in a seat, the pressure sensor under that seat is triggered. The logic processing unit looks up the pre-stored coordinate value corresponding to that seat according to the triggered sensor number and uses it as the second position information. When multiple seats are occupied, the system can prioritize the driver's seat position as the second position information, or provide guidance to all occupants simultaneously.

[0055] In this embodiment of the invention, in-vehicle sensors are used to detect vehicle collision events, including at least one of an acceleration sensor and an airbag sensor. The acceleration sensor monitors changes in acceleration in all directions of the vehicle in real time, and the airbag sensor detects whether the airbag has deployed. When the acceleration value detected by the acceleration sensor exceeds a preset threshold, the preset threshold can be calibrated according to the vehicle model, installation location, and safety standards. For example, for an acceleration sensor installed on the longitudinal axis of the vehicle chassis, the preset threshold can be set to a value within the range of 2g to 5g; for a lateral acceleration sensor, the preset threshold can be set to a value within the range of 1.5g to 3g. Alternatively, when the airbag sensor detects an airbag deployment signal, it is directly determined that a serious collision has occurred.

[0056] In this embodiment of the invention, a backup power module is used to provide power backup when the vehicle's main power supply is interrupted due to an accident. The backup power module can be a battery or supercapacitor module independent of the vehicle's main battery. When an interruption of the vehicle's main power supply is detected, the backup power module automatically switches to power supply mode, supplying power to the units related to the guidance function in the vehicle control module (including at least a logic processing unit, a display unit, and a voice module), the positioning beacon and audio-visual indicator device of the smart first aid kit, and the positioning base station of the in-vehicle positioning network, ensuring that the guidance function can still operate normally in the event of a main power failure.

[0057] In this embodiment of the invention, the vehicle component actuator is connected to the vehicle control module and includes a trunk locking mechanism and / or an electric strut. When needed, the vehicle control module can send a control signal to the vehicle component actuator to automatically unlock or open the trunk, allowing occupants to quickly access the first-aid kit located in the trunk.

[0058] Based on the above system composition, referring to Figure 2 The vehicle control module is configured to perform the following functions:

[0059] The vehicle control module receives trigger signals. These trigger signals can originate from two sources, either independently or in tandem. The first is voice triggering, where the voice recognition unit generates a signal upon recognizing a preset emergency voice command. The voice recognition unit continuously monitors the vehicle's audio, and upon recognizing a preset emergency voice command, generates a voice trigger signal and sends it to the logic processing unit. The second is collision triggering, where the logic processing unit generates a collision trigger signal based on collision detection signals from in-vehicle sensors. When the acceleration value detected by the accelerometer exceeds a preset threshold, or the airbag sensor detects an airbag deployment signal, the logic processing unit determines a serious collision has occurred and automatically generates a collision trigger signal. This dual-trigger mechanism ensures the system is activated regardless of whether the occupants actively speak.

[0060] In response to the received trigger signal, the vehicle control module sends a wake-up command to the smart first aid kit via the wireless communication module, activating the positioning beacon on the kit. Once activated, the beacon begins broadcasting a positioning signal. Multiple positioning base stations in the in-vehicle positioning network receive this signal, and the logic processing unit calculates the first location information of the smart first aid kit in the vehicle coordinate system based on the time difference or time of flight of the signals received by each base station. Simultaneously, the vehicle control module obtains the second location information of the occupant in the vehicle coordinate system through the occupant positioning unit. The occupant positioning unit determines the occupant's seat by detecting the trigger status of each seat pressure sensor and reads the pre-stored coordinate value corresponding to that seat as the second location information.

[0061] After obtaining the first and second location information, the logic processing unit calculates the relative orientation and distance between them to generate guidance information. The guidance information includes a description of the smart first-aid kit's orientation and distance relative to the occupant. For example, the orientation description could be "under the left rear seat" or "left side storage compartment in the trunk," and the distance information could be a calculated relative distance value.

[0062] After the guidance information is generated, the vehicle control module outputs guidance in a multimodal manner. Specifically, the control display unit displays the guidance information, including a schematic diagram of the vehicle's interior, and marks the location of the smart first aid kit in real time with dynamic arrows or flashing icons. The control voice module outputs voice navigation corresponding to the guidance information, such as announcing, "The first aid kit is located under your right rear seat, and the light is flashing." Simultaneously, the sound and light indicator on the smart first aid kit emits an indication signal, and the wireless communication module sends control commands to the smart first aid kit, causing its LED light strip to flash at a high frequency and its buzzer to emit intermittent beeps to guide the occupant to retrieve the first aid kit.

[0063] Before or during the output of guidance information, the vehicle control module actively acquires the status information of the smart first aid kit via the wireless communication module and broadcasts it via the voice module. The status information includes whether the first aid kit is in place, the remaining power of the built-in battery, and the expiration date of the medications. The medication expiration date is entered by the user through the medication entry detection unit and stored in the first aid kit's memory when the medication is placed inside. The vehicle control module reads the expiration date information and, combined with the current time, determines whether the medication is expired or nearing its expiration date. For example, the system may announce: "First aid kit is ready" or "Please note, the tourniquet has expired." This allows occupants to understand the status of the supplies before taking them, making rescue operations more prepared.

[0064] After the first aid kit is taken, the system can detect changes in the status of the medicine slot through in-situ sensors, or the user can manually confirm the taking through the vehicle's infotainment system, record the usage of the items, and generate a replenishment reminder message to indicate the medicines or equipment that need to be replenished.

[0065] In some embodiments of the present invention, the vehicle-mounted first aid kit guidance system also has a routine medication management function. Each time the vehicle is powered on and started, the vehicle control module automatically executes the medication management process: connecting to the smart first aid kit via a wireless communication module to read the stored medication expiration date and location information. The expiration date information is entered and stored by the medication entry detection unit when the user previously placed the medication in the first aid kit. The location information is detected in real time by a location sensor.

[0066] The logic processing unit compares the expiration dates of each medication with the current time on the vehicle's infotainment system. If the expiration date has passed, the medication is considered expired; if the remaining days are less than a preset number (e.g., 30 days), it is considered nearing expiration. Simultaneously, the logic processing unit determines if any medication is missing based on availability information. When expired, nearing, or missing medications are detected, the system control display unit displays a reminder card and controls the voice module to announce, for example, "Expired tourniquet and missing adhesive bandages have been detected in the first-aid kit. Please replenish or replace them promptly." This enables proactive daily management of medications in the vehicle's first-aid kit, ensuring the kit is always in a readily available and effective state.

[0067] The system of the present invention will be further described below in conjunction with several typical application scenarios.

[0068] Example 1: Automatic system guidance after a traffic accident:

[0069] A severe frontal collision occurred, airbags deployed, main power was interrupted, lighting failed, and smoke filled the vehicle. Accelerometers and airbag sensors transmitted collision detection signals to the vehicle's infotainment system. The backup power module detected the main power interruption and immediately switched to backup power for core functions. The logic processing unit generated a collision trigger signal based on the collision detection signals. The system then activated the UWB beacon on the smart first-aid kit via the wireless communication module. The pre-installed UWB base station network quickly determined that the first-aid kit was located under the passenger seat. Simultaneously, the occupant positioning unit detected that the driver's seat pressure sensor had been triggered, using the driver's seat's pre-stored coordinates as secondary location information. The infotainment screen illuminated, displaying a simple guidance interface with a flashing arrow pointing to the first-aid kit's location. The voice module announced: "Accident detected. First-aid kit located under the passenger seat, flashing lights." Simultaneously, the LED strip on the first-aid kit began flashing rapidly, and a buzzer emitted an urgent warning sound. Injured passengers or rescuers arriving at the scene, guided by light and sound, quickly located and retrieved first-aid kits despite obstructed vision, and provided first aid to stop the bleeding and bandage the wounded, thus gaining precious golden rescue time.

[0070] Example 2: Voice-triggered guidance for sudden illness:

[0071] A passenger experiences sudden angina during a long journey, and the driver, needing to remain focused on driving, cannot be distracted by searching for a first-aid kit. The passenger simply says, "In-vehicle system, I need a first-aid kit." The voice recognition unit immediately recognizes the pre-set command, generates a voice trigger signal, and the system is activated. The in-vehicle UWB positioning network quickly calculates that the first-aid kit is located in the left-hand storage compartment of the trunk. The occupant positioning unit detects that the passenger seat pressure sensor has been triggered, using the seat's coordinates as secondary location information. The in-vehicle system screen displays a guidance diagram, and the voice module announces, "The first-aid kit has been located in the left-hand storage compartment of the trunk; we are opening the trunk for you." The in-vehicle control module sends control signals to the vehicle's actuators, unlocking the trunk locking mechanism, and the electric strut opens the trunk a pre-set gap. The LED light for the first-aid kit in the designated storage compartment begins to flash frequently. After the driver pulls over to a safe location, the passenger, following the light and sound from the gap in the trunk, quickly retrieves the first-aid kit.

[0072] Example 3: Routine Medication Status Monitoring and Reminders:

[0073] A user who requires long-term medication stored antihypertensive and antihistamine medications in their car's first-aid kit. When placing the medications, the user entered the medication names and expiration dates using the input device on the kit, which was then stored in the memory. After some time, some medications were used up, and others expired. One day, the user started the vehicle, and the vehicle's infotainment system automatically executed the medication management process upon powering on. The infotainment module read the medication expiration dates from the first-aid kit's memory via Bluetooth, as well as the presence information detected by the presence sensors. It determined that the antihypertensive medications had expired and the presence sensor for the antihistamines had not detected any medication. The system immediately displayed a notification on the central control screen and announced via voice: "Expired antihypertensive medication detected; antihistamines missing. Please replenish or replace them promptly." The user was informed of this situation before departure, allowing for immediate action and preventing the problem of being without medication in case of a sudden illness during the journey.

[0074] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
