Description

Technical Field

[0001] The present invention relates to a driving assistance system, and more particularly to a driving safety warning and prompting system and method for diabetic patients. Background Art

[0002] Research has found that sudden hypoglycemia during driving may cause symptoms such as dizziness, tremors, and palpitations, and in severe cases, loss of consciousness or coma, directly affecting vehicle control ability. Long-term hyperglycemia leads to blurred vision, visual field defects, or accommodation disorders, affecting road condition judgment. Diabetic retinopathy is often accompanied by a decrease in dark adaptation ability, increasing the risk coefficient of night driving. Myocardial ischemia or arrhythmia caused by diabetes may trigger chest pain and syncope, resulting in vehicle out of control. Patients with combined hypertension are prone to dizziness or visual field abnormalities due to sudden increase in blood pressure. Hyperglycemia reduces the concentration of attention and increases the probability of fatigue driving. Therefore, if a diabetic patient needs to drive, the blood sugar should be ensured to be stable in the range of 5.0 - 10.0 mmol / L, carry a blood glucose meter and fast-acting sugar-raising foods with them, and regularly undergo ophthalmological, cardiovascular, and neurological function examinations.

[0003] However, due to the needs of life and work, diabetic patients inevitably need to carry out driving operations. Different from ordinary drivers, diabetic patients should pay special attention to their blood sugar levels during driving to ensure that their blood sugar is within a continuously controllable range during driving to ensure driving safety. However, the current vehicles or driving systems on the market do not address the needs of this group of people, resulting in potential safety hazards and even frequent traffic accidents.

[0004] Therefore, there is a wide market prospect for providing a system that can provide driving safety warning and prompting for diabetic patients, interconnected with the vehicle-mounted system for continuous monitoring, aiming to improve the driving safety of this group of people, and a driving safety warning and prompting system and method for diabetic patients with simple and easy-to-operate methods. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a driving safety warning and prompting system and method for diabetic patients with a simple structure, convenient operation, capable of being interconnected with the vehicle-mounted system for continuous monitoring, effectively improving the driving safety of diabetic patients during travel, and with simple and easy-to-operate methods, to overcome the defects in the prior art.

[0006] The technical solution of the present invention is realized as follows: A driving safety warning and prompting system for diabetic patients includes an in-vehicle host, a front windshield, and an in-vehicle audio system. The in-vehicle host is respectively connected to an in-vehicle non-invasive blood glucose meter, an in-vehicle projector, and an in-vehicle monitor. The in-vehicle non-invasive blood glucose meter is connected to the in-vehicle host through a mobile controller. The in-vehicle projector projects safety warning information at the projection working layer A position on the front windshield. The in-vehicle monitor monitors the driver's body temperature and fatigue status in real time. The in-vehicle audio system plays voice safety warning information according to the prompts of the in-vehicle monitor and the in-vehicle non-invasive blood glucose meter.

[0007] Further, a driving safety warning and prompting system for diabetic patients includes an in-vehicle host, a front windshield, and an in-vehicle audio system. The in-vehicle host is connected to a mobile controller, and the mobile controller is respectively connected to an in-vehicle non-invasive blood glucose meter, an in-vehicle projector, and an in-vehicle monitor. The in-vehicle projector projects safety warning information at the projection working layer A position on the front windshield. The in-vehicle monitor monitors the driver's body temperature and fatigue status in real time. The in-vehicle audio system plays voice safety warning information according to the prompts of the in-vehicle monitor and the in-vehicle non-invasive blood glucose meter.

[0008] Further, the in-vehicle monitor is located on one side of the front windshield at the front end of the driver, and an infrared camera and a monitoring camera are installed on the in-vehicle monitor.

[0009] Further, the in-vehicle projector is located at the lower part of the front windshield at the front end of the driver.

[0010] Further, the in-vehicle non-invasive blood glucose meter is connected to a finger insertion cylinder through a rotating shaft. A light source emitter and a light source receiver that cooperate with each other are arranged on the inner wall of the finger insertion cylinder. The light source emitter and the light source receiver are connected to a spectral analyzer installed in the in-vehicle non-invasive blood glucose meter through wires. The spectral analyzer is connected to a data processing module installed in the in-vehicle non-invasive blood glucose meter. The data processing module is connected to the mobile controller through a wire.

[0011] Further, the in-vehicle projector is an HUD projection device.

[0012] Further, a processor for performing data conversion and analysis on the in-vehicle monitor is installed in the in-vehicle host or the mobile controller.

[0013] A safety warning and prompting method for the driving safety warning and prompting system for diabetic patients as described above, the method is:

[0014] After a diabetic driver gets into the vehicle, first turn on the in-vehicle host, and then insert a finger into the finger insertion cylinder. When the light source emitter penetrates the skin, subcutaneous glucose molecules absorb the light waves of the light source emitter or produce a scattered spectrum. Then, the light source receiver collects the reflected light waves or scattered spectrum, and a spectral analyzer collects the data. After being processed by the data processing module, the information is input into the in-vehicle host through the mobile controller. After receiving the information, the in-vehicle host plays the blood glucose measurement value through the in-vehicle audio, so as to obtain the blood glucose information of the diabetic driver before driving. When the blood glucose information of the diabetic driver meets the driving safety level, the diabetic driver starts the vehicle to drive. During the driving process, multiple detections can be carried out. The in-vehicle host will send a prompt detection signal within a preset time period and play a prompt tone through the in-vehicle audio. During the driving process, the infrared camera and the monitoring camera continuously monitor the body temperature and facial fatigue status of the diabetic driver, and transmit the collected information to the in-vehicle host. After analyzing the collected information through the built-in processor of the in-vehicle host, the safety warning prompt information is projected onto the projection working layer A through the in-vehicle projector, and at the same time, the safety warning prompt information is played through the in-vehicle audio;

[0015] Alternatively, after a diabetic driver gets into the vehicle, first turn on the in-vehicle host, and then insert a finger into the finger insertion cylinder. When the light source emitter penetrates the skin, subcutaneous glucose molecules absorb the light waves of the light source emitter or produce a scattered spectrum. Then, the light source receiver collects the reflected light waves or scattered spectrum, and a spectral analyzer collects the data. After being processed by the data processing module, the information is input into the in-vehicle host through the mobile controller. After receiving the information, the in-vehicle host plays the blood glucose measurement value through the in-vehicle audio, so as to obtain the blood glucose information of the diabetic driver before driving. When the blood glucose information of the diabetic driver meets the driving safety level, the diabetic driver starts the vehicle to drive. During the driving process, multiple detections can be carried out. The mobile controller will send a prompt detection signal within a preset time period and play a prompt tone through the in-vehicle audio. During the driving process, the infrared camera and the monitoring camera continuously monitor the body temperature and facial fatigue status of the diabetic driver, and transmit the collected information to the mobile controller. After analyzing the collected information through the built-in processor of the mobile controller, the safety warning prompt information is projected onto the projection working layer A through the in-vehicle projector, and at the same time, the safety warning prompt information is played through the in-vehicle audio.

[0016] The present invention has the following positive effects:

[0017] 1. The present invention uses the in-vehicle host or the mobile controller as the carrier of the safety warning and reminder system, and comprehensively monitors the safety of diabetic patients before and during driving by using the in-vehicle non-invasive blood glucose meter, in-vehicle projector, in-vehicle monitor, and in-vehicle audio distributed in the vehicle. At the same time, it is visually displayed through the projection working layer A feedback to the front windshield, and the in-vehicle audio is used as the reminder playback device to ensure the all-round safety protection of diabetic patients during driving. Through the sound and light reminder method, the blood glucose information of the driver is comprehensively monitored and reminded to ensure that the blood glucose is within a continuously controllable range during driving to ensure driving safety.

[0018] 2. The present invention realizes the interconnection between the driving safety warning and reminder of diabetic patients and the in-vehicle system for continuous monitoring, which helps to improve the driving safety of diabetic patients when traveling. The whole adopts an in-vehicle fixed installation, uses the in-vehicle host as the bearing unit of the whole system to realize the interconnection of monitoring equipment, projection equipment, and acquisition equipment, or uses the mobile controller as a movable installation component, connects it to the in-vehicle host through a data cable, and connects the mobile controller to the monitoring equipment, projection equipment, and acquisition equipment. The movable installation is realized through the mobile controller. The product adopts a detachable and flexible installation method and a method of fixing some components on the vehicle, which is suitable for different groups of people with different needs.

[0019] 3. The present invention realizes the movable or fixed installation of the in-vehicle non-invasive blood glucose meter on a specific part of the vehicle body, and performs non-invasive measurement of blood glucose through the light source emitter and light source receiver installed in the finger insertion cylinder. The measurement is painless. At the same time, before driving and during the driving process without affecting driving safety, rapid measurement operations can be carried out through the finger insertion cylinder, and the data information can be analyzed and processed by the mobile controller, and finally a signal that can be recognized by the in-vehicle host is formed for audio-visual reminder, providing real-time reminder and warning during driving, and giving a timely warning to the driver when the preset warning value is reached, so as to ensure the occurrence of safety hazards during the driving of diabetic patients.
