Description

Technical Field

[0001] This utility model relates to the field of vehicle safety alarm technology, specifically to a vehicle safety alarm system for intelligent steering wheel data acquisition and analysis. Background Technology

[0002] Most existing vehicle safety alarm systems only have basic warning functions and cannot monitor and assess the driver's physiological state in real time, nor can they detect and handle abnormal driver behavior in a timely manner. Therefore, by setting up corresponding sensors on the steering wheel to collect and analyze the driver's physiological data, it is possible to monitor, assess and warn the driver's physiological state and abnormal behavior in real time, so as to avoid vehicle accidents caused by driver fatigue or sudden cardiovascular disease.

[0003] For example, Chinese patent application CN201921483436.5 discloses a driver's electrocardiogram (ECG) detection system, which uploads the data from each measurement to a data management platform, enabling rapid management and storage of user measurement data. Another example is Chinese patent application CN201920983446.9, which discloses a car steering wheel structure for measuring human health indicators. This system can monitor the driver's physical condition in real time, and when an alarm is detected, it will sound to remind the driver to pay attention to their physical condition, reducing the risk of adverse situations for the driver during the drive. However, both of these system structures require the system to be constantly connected to the network during actual use. When the vehicle is in an uninhabited area or an area with no or weak signal and the driver experiences cardiovascular abnormalities, the ECG signal of the driver often cannot be promptly fed back for emergency treatment, which cannot effectively assist emergency doctors in their diagnosis and treatment.

[0004] At the same time, although existing data is generally backed up in the processor during processing, when a vehicle is involved in a driving accident (collision, rollover, etc.), it is easy to cause some damage to the electronic components inside the vehicle. There may be some deficiencies in data storage, and the driver's real-time physiological state while driving cannot be effectively stored. In the event of a driving accident, timely emergency assistance and accident liability determination cannot be carried out.

[0005] Therefore, this application proposes a vehicle safety alarm system for intelligent steering wheel data acquisition and analysis to solve the above-mentioned technical problems. The above content is only used to assist in understanding the technical solution of this application and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0006] The main purpose of this utility model is to provide a vehicle safety alarm system that can both issue an alarm when the driver experiences abnormal physical and physiological conditions and store the driver's electrocardiogram (ECG) data on physical and physiological conditions in real time via a memory card during vehicle driving, so as to completely preserve the ECG data in case of an accident.

[0007] To address the aforementioned technical problems, this utility model provides a vehicle safety alarm system for intelligent steering wheel data acquisition and analysis, comprising a steering wheel body, a sensing component located on the steering wheel body, and an alarm device installed on the steering wheel body.

[0008] The steering wheel body is used to detect the driver's electrocardiogram (ECG) signal; the amplifier and analog-to-digital converter are connected in sequence to the data processor and the memory card slot structure to process the ECG signal data and store it in the memory card slot structure.

[0009] In addition, it also includes:

[0010] The memory card slot structure is set on the steering wheel body and consists of a protective shell with one end open, a memory card body inserted into the opening of the protective shell, and a clamping member set inside the protective shell for pressing and fixing the memory card body. When the clamping member presses and fixes the memory card body, the memory card body is used to store the information data obtained by the sensing component through the reader.

[0011] The sensing components include an electrocardiogram (ECG) sensor located outside the steering wheel body for detecting the driver's ECG signal, and an amplifier, an analog-to-digital converter, and a data processor connected in sequence to the ECG sensor.

[0012] Furthermore, the steering wheel body is also equipped with a display connected to the data processor via a data transmission line, for displaying ECG signal data processed by an amplifier and an analog-to-digital converter in real time.

[0013] Furthermore, the steering wheel body is also equipped with a camera for recording the driver's face;

[0014] When the alarm is triggered, the camera starts recording the driver's face and the recorded data is transferred to the memory card via a reader.

[0015] Furthermore, the steering wheel body is also equipped with a signal transmitter for uploading ECG signal data processed by an amplifier and an analog-to-digital converter to the network cloud when connected to the network.

[0016] When the alarm is triggered, the signal transmitter is used to upload the camera recording data to the cloud.

[0017] Furthermore, the data processor performs data processing based on any one of the GD32F403 chip, GD32F450 chip, and GD32F470 chip.

[0018] Furthermore, the clamping member is configured as a plate-shaped member, and the clamping member is connected to multiple sets of compression springs located inside the protective housing for driving the clamping member to press against the memory card body.

[0019] Furthermore, the clamping member extends out of the protective housing and is provided with a sliding protrusion that fits against the outside of the opening of the protective housing, for limiting the sliding of the clamping member within the protective housing.

[0020] Furthermore, the end of the clamping member extending out of the protective housing is also provided with a limiting protrusion for limiting the movement of the memory card body when the clamping member is pressed against the memory card body.

[0021] Furthermore, the limiting protrusion is provided with a groove, which is used to manually pull the limiting protrusion through the groove to separate the clamping member from the memory card body.

[0022] Furthermore, the alarm can be configured as an audible and visual alarm.

[0023] The beneficial effects of this utility model are reflected in:

[0024] 1. This utility model collects the driver's physiological data in real time by setting a corresponding electrocardiogram (ECG) sensor on the steering wheel. The data is then converted into digital signals by an amplifier and an analog-to-digital converter and analyzed in a data processor. This enables real-time monitoring, evaluation, and early warning of the driver's physiological state and abnormal behavior, preventing vehicle accidents caused by driver fatigue or sudden cardiovascular disease. Simultaneously, an alarm is set on the steering wheel body, which can issue an alarm when the ECG sensor reaches the fatigue driving assessment threshold (i.e., when the driver's physical and physiological condition is abnormal) to indicate that the driver is in a state of driving fatigue. The driver's ECG information at this time can also be displayed on the monitor.

[0025] 2. This utility model, by setting an alarm on the steering wheel body, can also issue an alarm after the electrocardiogram reaches the maximum assessment threshold (i.e. when the driver has abnormalities such as cardiovascular disease), indicating that the driver is in a critical condition, and can send out rescue location information through a signal transmitter.

[0026] 3. This utility model, by setting a memory card slot structure on the steering wheel body, utilizes the memory card body to independently store the converted and analyzed electrocardiogram (ECG) data. Thus, during vehicle driving, the driver's physical and physiological ECG data information can be stored in real time via the memory card to completely save ECG data in case of accidents, and can be used for emergency assistance and accident liability determination. It has good practicality and safety.

[0027] 4. By setting up a memory card slot structure, this utility model uses a sliding protrusion limiting clamping member to move within the protective housing. The limiting protrusion limits the memory card chip located within the protective housing. In the event of an accident while the vehicle is in motion, multiple sets of compression springs can work together to ensure that the memory card chip is always located within the protective housing, thereby stably and safely protecting the data information stored in the memory card chip.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0036] For details in the embodiments, please refer to Figures 1 to 4 .

[0037] like Figures 1 to 3As shown, this utility model provides a vehicle safety alarm system for intelligent steering wheel data acquisition and analysis, which consists of a steering wheel body 1, a sensing component located on the steering wheel body 1, and an alarm 3 installed on the steering wheel body 1. The alarm 3 can be set as any one of the existing sound and light alarm and buzzer alarm.

[0038] In addition, it also includes:

[0039] The memory card slot structure 6 is set on the steering wheel body 1 and consists of a protective shell 61 with one end open, a memory card body 63 inserted into the opening of the protective shell 61, and a clamping member 64 set inside the protective shell 61 for pressing and fixing the memory card body 63. When the clamping member 64 presses and fixes the memory card body 63, the memory card body 63 is used to store the information data obtained by the sensing component through the reader 62.

[0040] At this time, by independently storing and analyzing the converted ECG data using the main body 63 of the memory card, the driver's physical and physiological ECG data information can be stored in real time during vehicle driving. This allows for the complete preservation of ECG data in case of an accident and its use in emergency assistance and accident liability determination, demonstrating excellent practicality and safety.

[0041] It should also be noted here that the data reading and storage of the memory card body 63 by the reader 62 is a conventional structure of the data connection of the existing memory card body 63. Therefore, the specific principle and structure of the reader 62 will not be described in detail here. Please refer to the existing patent (a memory card reader with application number CN201710262978.9).

[0042] In addition, the sensing components include an electrocardiogram sensor 11 located outside the steering wheel body 1 for detecting the driver's electrocardiogram signal, an amplifier 12 connected in sequence to the electrocardiogram sensor 11 for amplifying and processing the electrocardiogram signal, an analog-to-digital converter 13 connected to the amplifier 12 for converting the amplified electrocardiogram signal into a digital signal, and a data processor 14 for processing the digital signal.

[0043] By setting up a corresponding electrocardiogram sensor 11 on the steering wheel to collect the driver's physical physiological data in real time and converting it into digital signals through an amplifier 12 and an analog-to-digital converter 13 for analysis in the data processor 14, the driver's physiological state and abnormal behavior can be monitored, evaluated and warned in real time, so as to avoid the driver causing vehicle accidents due to fatigue driving or sudden cardiovascular disease. At this time, an alarm 3 is set on the steering wheel body 1. (1) It can issue an alarm after the electrocardiogram reaches the fatigue driving assessment threshold (i.e. when the driver has abnormal physical and physiological conditions) to indicate that the driver is in a state of driving fatigue; (2) It can issue an alarm after the electrocardiogram reaches the maximum assessment threshold (i.e. when the driver has abnormal diseases such as cardiovascular disease) to indicate that the driver is in a disease crisis.

[0044] It should be noted that the data processor 14 here is based on the existing GD32F403 chip, GD32F450 chip or GD32F470 chip for data processing, with the GD32F470 chip being the best.

[0045] It should also be noted that the ECG sensor 11, amplifier 12, and analog-to-digital converter 13 here can all refer to existing patents (amplifier 12 and analog-to-digital converter 13 are based on an ECG acquisition chip, which can refer to an ECG signal processing chip with application number CN201921275366.4; the ECG sensor 11 can refer to the same structure as a steering wheel with a driver health data acquisition device with application number CN202123442722.7, and the ECG sensor 11 can also refer to this patent to add a body temperature sensor and a heart rate sensor).

[0046] Furthermore, the steering wheel body 1 is also equipped with a display 2 connected to the data processor 14 via a data transmission line, which is used to display the electrocardiogram signal data processed by the amplifier 12 and the analog-to-digital converter 13 in real time.

[0047] Therefore, when alarm 3 sounds to indicate that the driver is in a state of driving fatigue, the driver's electrocardiogram information at this time can be displayed on display 2.

[0048] Furthermore, the steering wheel body 1 is also equipped with a camera 4 for recording the driver's face. When the alarm 3 is triggered, the camera 4 can be turned on and record the driver's face, and the recorded data is entered into the memory card body 63 through the reader 62 for emergency assistance in the event of a driving accident.

[0049] At the same time, camera 4 can also play a certain role in recording video to prevent theft and ensure the safety of the driver's vehicle and property.

[0050] Furthermore, the steering wheel body 1 is also equipped with a signal transmitter 5 for uploading ECG signal data processed by amplifier 12 and analog-to-digital converter 13 to the network cloud when the network is connected. When the alarm 3 is triggered, the signal transmitter 5 is used to upload the video data of camera 4 to the network cloud. At the same time, when the alarm 3 sounds an alarm to indicate that the driver is in a medical crisis, the signal transmitter 5 can also send out rescue location information.

[0051] It should be noted that the signal transmitter 5 here can directly adopt existing signal radio frequency equipment, or can refer to other existing technologies (for example, you can directly refer to the data transmission method and apparatus based on modulated signals in application number CN201710652076.6).

[0052] like Figure 3 and Figure 4 As shown, in one specific embodiment, the clamping member 64 of the memory card slot structure 6 is configured as a plate-shaped member, and the clamping member 64 is connected to multiple sets of compression springs 65 located inside the protective housing 61 for driving the clamping member 64 to press against the memory card body 63.

[0053] The clamping element 64 here can be a sheet-shaped part made of rubber.

[0054] At this time, the clamping member 64 extends out of the protective housing 61 and is provided with a sliding protrusion 66 that fits against the outside of the opening of the protective housing 61, which is used to limit the sliding movement of the clamping member 64 within the protective housing 61.

[0055] At this time, the clamping member 64 extends out of the protective housing 61 and is also provided with a limiting protrusion 67 for limiting the movement of the memory card body 63 when the clamping member 64 is pressed and attached to the memory card body 63.

[0056] Therefore, in the event of an accident while the vehicle is in motion, multiple sets of compression springs 65 can ensure that the memory card chip is always inside the protective housing 61, thereby stably and safely protecting the data information stored in the memory card chip.

[0057] Furthermore, the limiting protrusion 67 is provided with a groove 68, which is used to manually pull the limiting protrusion 67 through the groove 68 to separate the clamping member 64 from the memory card body 63.

[0058] When the memory card body 63 is inserted into the protective housing 61, the limiting protrusion 67 can be manually pulled through the groove 68 to drive the clamping member 64 to move within the protective housing 61. At this time, the compression spring 65 is compressed and tightened. The limiting protrusion 67 and the clamping member 64 are exposed at the opening of the protective housing 61 to facilitate the insertion or removal of the memory card body 63. When the groove 68 on the limiting protrusion 67 is not under force, the compression spring 65 opens to drive the clamping member 64 to move towards the memory card chip placement part and press it. At this time, the limiting protrusion 67 of the clamping member 64 blocks the opening of the protective housing 61 to limit the memory card body 63.

[0059] Furthermore, the protective housing 61 is made of carbon fiber, and the inside of the protective housing 61 is coated with an antistatic layer and the outside is coated with a fireproof layer. Since the memory card body 63 is partially exposed to the air inside the protective housing 61 in conjunction with the clamping member 64, its internal heat dissipation can be guaranteed.

[0060] When a vehicle is involved in a driving accident, the protective housing 61 has certain fireproof and pressure-resistant properties, which can strongly protect the memory card chip and further protect the driver's electrocardiogram signal data while driving the vehicle. This data can then be used to assist doctors in emergency judgment or other related matters.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0062] Furthermore, it should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0063] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

Furthermore, in the embodiments of this utility model, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
