Detailed Implementation

[0013] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Figure 1 This is a flowchart illustrating an emergency alarm method provided in an embodiment of this application. This emergency alarm method can be executed by an emergency alarm device, which can be implemented in software and / or hardware and integrated into the vehicle, for example, a digital key controller or a vehicle-mounted terminal (TBOX). See also... Figure 1 The emergency alarm method specifically includes the following steps: S110, Receive emergency information.

[0016] For example, receiving emergency information includes: It can receive emergency information input by users through the central control screen or user terminals (such as smartphones, smartwatches, and other terminals that communicate with the vehicle); or it can receive emergency information input by users through voice.

[0017] It supports both voice input and text input of emergency information.

[0018] In some implementations, emergency information types can be preset. When a user encounters an emergency, they can directly select the corresponding emergency information type, such as "sudden illness", "vehicle malfunction", or "a patient in the vehicle urgently needs to go to the hospital". Users can directly select the corresponding emergency information type according to the emergency situation they encounter through the menu items displayed on the central control screen, thereby simplifying user operation, reducing the difficulty of use, and improving the user experience.

[0019] S120. Generate a notification message based on the emergency information.

[0020] For example, generating a notification message based on the emergency information includes: Determine the identification code corresponding to the emergency information; encapsulate the identification code and the current vehicle's associated information according to a preset format to generate the notification message.

[0021] The identification code is a digital representation of the emergency information. Converting emergency information into a digital representation facilitates its communication and transmission. For example, the identification code for the emergency information type "sudden illness" is 01, the identification code for the emergency information type "vehicle breakdown" is 02, and the identification code for the emergency information type "a patient in the vehicle urgently needs to go to the hospital" is 03, etc.

[0022] The associated information of the current vehicle includes, but is not limited to: the current location of the vehicle, license plate number, vehicle color, vehicle model, and other information that is easily identifiable by surrounding vehicles and pedestrians.

[0023] Encapsulating the identification code and the current vehicle's associated information according to a preset format essentially means processing the identification code and the current vehicle's associated information into a data packet that can be sent via the Bluetooth channel, in accordance with the requirements of the Bluetooth communication protocol.

[0024] S130. The notification message is sent via the vehicle's Bluetooth chip so that other devices with Bluetooth chips within a preset range of the current vehicle can receive the notification message.

[0025] Specifically, the in-vehicle Bluetooth chip can be a Bluetooth Low Energy (BLE) chip.

[0026] The preset range is determined by the Bluetooth communication distance. Bluetooth communication distance is affected by various factors, typically ranging from 10 to 100 meters. Transmission power is the core factor affecting communication distance, usually measured in dBm. Higher transmission power indicates stronger power and a longer communication distance. For example, low power (-20dBm to -40dBm) generally has a communication distance of 1-10 meters, suitable for devices such as headphones and smart bracelets; medium power (0dBm to -10dBm) generally has a communication distance of 10-50 meters, commonly found in smart home devices; and high power (5dBm to 20dBm) generally has a communication distance of 50-100 meters, often used in industrial IoT gateways. Environmental interference affects communication distance; for example, walls, metal, and people can weaken the signal, leading to a shorter communication distance. Electromagnetic interference, due to frequency band overlap, causes signal attenuation, further reducing the effective communication distance.

[0027] For example, see references to Figure 2The diagram illustrates an emergency alarm system where the vehicle 210 sends a notification message to the outside world via its onboard Bluetooth chip. Other devices with Bluetooth chips within a preset range of the vehicle receive the notification message, enabling recipients to take actions such as giving way or providing assistance based on the message's content. In emergency situations, such as hospitals or emergency vehicles (ambulances, police cars), Bluetooth devices receiving the notification message can prepare for rescue in advance, improving rescue efficiency.

[0028] Other devices with Bluetooth chips within a preset range of the vehicle can broadcast or display the notification message upon receiving it, thereby reminding the user that they have received the notification. Specifically, the notification message can be displayed on the vehicle's central control screen or broadcast via the in-vehicle voice device. If the receiving device is a smartphone, the notification can also be displayed in two ways: by displaying a text notification or by broadcasting the notification via voice.

[0029] The emergency alarm method provided in this application includes: receiving emergency information; generating a notification message based on the emergency information; and sending the notification message via an in-vehicle Bluetooth chip so that other devices with Bluetooth chips within a preset range of the current vehicle can receive the notification message. By sending emergency alarm notifications to the outside world based on the vehicle's built-in low-power Bluetooth chip, the utilization rate of the built-in low-power Bluetooth chip is improved, and the emergency alarm effect is enhanced. Especially in scenarios with blind spots such as intersections, compared with traditional emergency alarm methods such as honking the horn and flashing lights, this application significantly improves the emergency alarm effect by sending emergency alarm notifications to the outside world via the vehicle's built-in low-power Bluetooth chip.

[0030] In some implementations, a dynamic communication channel allocation strategy is incorporated to further improve the success rate of notification message transmission, ensuring that notification messages are transmitted using channels with better communication quality, thereby improving the success rate of notification message transmission.

[0031] Specifically, there are multiple vehicle-mounted Bluetooth chips. Before sending the notification message through the vehicle-mounted Bluetooth chips, the method further includes: allocating a communication channel for each vehicle-mounted Bluetooth chip so that each vehicle-mounted Bluetooth chip can send the notification message according to the allocated communication channel.

[0032] For example, communication channels are allocated to each vehicle Bluetooth chip based on the interference strength of each communication channel and / or the installation location of each vehicle Bluetooth chip in the vehicle. For instance, a communication channel with lower interference strength is assigned to the vehicle Bluetooth chip with the optimal installation location in the vehicle, thereby enabling the vehicle Bluetooth chip with the optimal installation location to use the communication channel with the best communication quality to send notification messages, thus improving the success rate of notification message transmission through dual guarantees. Here, the vehicle Bluetooth chip with the optimal installation location in the vehicle refers to the Bluetooth chip with the least obstruction around its installation location; less obstruction results in better communication quality. For example, a Bluetooth chip installed on the vehicle roof can be considered the Bluetooth chip with the optimal location in the vehicle.

[0033] After allocating communication channels to each vehicle Bluetooth chip, each chip can monitor its own communication channel. If a high packet loss rate is detected on a particular channel, it can immediately switch to another channel for message transmission. For example, each Bluetooth chip polls and sends detection data packets (each channel is paused for 100ms) according to the allocation matrix (which records the communication channels allocated to each Bluetooth chip). When the packet loss rate of the current channel is detected to be greater than 30%, it immediately switches to a backup channel in the same group to ensure the success rate of notification message transmission.

[0034] In some embodiments, allocating communication channels for each of the vehicle-mounted Bluetooth chips based on the interference strength of each communication channel and / or the installation location of each of the vehicle-mounted Bluetooth chips in the vehicle includes: Determine the interference intensity of the communication channels; sort the communication channels in ascending order of interference intensity; allocate a predetermined number of the top-ranked communication channels to the target vehicle Bluetooth chip, which is a Bluetooth chip installed on the roof of the vehicle; allocate the remaining communication channels to other vehicle Bluetooth chips besides the target vehicle Bluetooth chip; or, allocate communication channels to each vehicle Bluetooth chip according to the sorted communication channels.

[0035] In this process, a predetermined number of communication channels are allocated to the target vehicle Bluetooth chip, which is a Bluetooth chip installed on the roof of the vehicle. Essentially, the communication channel with the best communication quality is allocated to the vehicle Bluetooth chip with the best installation location. The purpose is to ensure that the notification message is successfully sent through double protection.

[0036] In another embodiment, allocating communication channels to each of the vehicle Bluetooth chips according to the sorted communication channels includes: sequentially allocating communication channels to each vehicle Bluetooth chip according to equally spaced sampling. Specifically, the sorted communication channels are sampled at equal intervals for the first time to obtain a first sampling channel, and the first sampling channel is allocated to one of the vehicle Bluetooth chips; the remaining communication channels after sampling are sampled at equal intervals for the second time to obtain a second sampling channel, and the second sampling channel is allocated to the vehicle Bluetooth chips that have not been allocated a communication channel, until all vehicle Bluetooth chips have been allocated a communication channel.

[0037] like Figure 3 As shown, assuming there are 5 in-vehicle Bluetooth chips and the Bluetooth Low Energy chip typically has 40 communication channels, each in-vehicle Bluetooth chip can be allocated 8 communication channels. Further assuming the sorted communication channels are represented by numbers 1-40, and each vehicle Bluetooth chip is assigned a communication channel according to equal interval sampling, the communication channels assigned to the first vehicle Bluetooth chip are those represented by numbers 1, 6, 11, 16, 21, 26, 31, and 36; the communication channels assigned to the second vehicle Bluetooth chip are those represented by numbers 2, 7, 12, 17, 22, 27, 32, and 37; the communication channels assigned to the third vehicle Bluetooth chip are those represented by numbers 3, 8, 13, 18, 23, 28, 33, and 38; the communication channels assigned to the fourth vehicle Bluetooth chip are those represented by numbers 4, 9, 14, 19, 24, 29, 34, and 39; and the communication channels assigned to the fifth vehicle Bluetooth chip are those represented by numbers 5, 10, 15, 20, 25, 30, 35, and 40. The process involves first sampling the sorted communication channels at equal intervals to obtain first sampling channels (1, 6, 11, 16, 21, 26, 31, 36), and then assigning these first sampling channels to one of the vehicle-mounted Bluetooth chips. Next, the remaining communication channels are sampled at equal intervals a second time to obtain second sampling channels (2, 7, 12, 17, 22, 27, 32, 37), and these second sampling channels are assigned to any vehicle-mounted Bluetooth chips that have not yet been assigned a communication channel. This process continues until all vehicle-mounted Bluetooth chips have been assigned a communication channel. This configuration aims to allocate communication channels of comparable quality to different vehicle-mounted Bluetooth chips, ensuring that each Bluetooth chip receives a high-quality communication channel and thus guaranteeing stable transmission of notification messages.

[0038] Furthermore, in some embodiments, determining the interference intensity of the communication channel includes: Determine the received signal strength of the communication channel, the number of connected WIFI devices, and the current location information; determine the interference intensity of the communication channel based on the received signal strength of the communication channel, the number of connected WIFI devices, and the current location information.

[0039] The received signal strength of a communication channel can be determined as follows: Each Bluetooth chip takes turns switching to listening mode, scans the RSSI (Signal Strength Indicator) of channels 0-39, and outputs a 40-dimensional RSSI vector [rssi0, rssi1, ..., rssi39]. Specifically, if the RSSI of a channel is consistently greater than -65dBm (-65dBm is an adjustable threshold), the channel is marked as "high interference," and a list of interfering channels is output.

[0040] To reduce the impact of short-term interference, the received signal strength can be measured multiple times for each channel, and the average value can be used to determine the final received signal strength for that channel, thereby improving the accuracy of the received signal strength measurement. For example, the received signal strength of communication channel 1 can be measured 10 times, and the average value of these 10 measurements can be used to determine the final received signal strength of communication channel 1.

[0041] The interference strength of the communication channel can be determined based on the received signal strength, the number of connected Wi-Fi devices, and the current location information, which can be achieved in the following way:

[0042] in, Indicates communication channel ch The intensity of interference, , , The weighting factor can be set based on experience. Indicates communication channel ch The received signal strength, Indicates communication channel ch The number of connected Wi-Fi devices This represents the location correction factor determined based on the current location information, such as in a tunnel. The value is greater than that on the ground The value, in an open location The value is greater than that in locations surrounded by tall buildings. The value.

[0043] Correspondingly, see reference as follows Figure 4 As shown, the dynamic channel allocation engine allocates a communication channel to each Bluetooth chip based on the interference strength of the communication channel calculated by the TBOX calculation unit. The TBOX calculation unit determines the interference strength of the communication channel based on the current location information, received signal strength, and Wi-Fi overlap.

[0044] Based on the same inventive concept, corresponding to any of the above embodiments, this application also provides an emergency alarm device.

[0046] Furthermore, the number of the vehicle-mounted Bluetooth chips is multiple, and the emergency alarm device further includes: an allocation module, used to allocate a communication channel to each of the vehicle-mounted Bluetooth chips before sending the notification message through the vehicle-mounted Bluetooth chips, so that each of the vehicle-mounted Bluetooth chips sends the notification message according to the allocated communication channel.

[0047] Furthermore, the allocation module is specifically used to: allocate communication channels to each of the vehicle Bluetooth chips according to the interference strength of each communication channel and / or the installation location of each vehicle Bluetooth chip in the vehicle.

[0049] Furthermore, the determining unit is specifically used to determine the received signal strength of the communication channel, the number of connected WIFI devices, and the current location information; and to determine the interference intensity of the communication channel based on the received signal strength of the communication channel, the number of connected WIFI devices, and the current location information.

[0050] The allocation unit is specifically used for: performing a first equally spaced sampling on the sorted communication channels to obtain a first sampling channel, and allocating the first sampling channel to one of the vehicle Bluetooth chips; performing a second equally spaced sampling on the remaining communication channels after sampling to obtain a second sampling channel, and allocating the second sampling channel to the vehicle Bluetooth chips that have not been allocated a communication channel, until all vehicle Bluetooth chips are allocated a communication channel.

[0051] Furthermore, the generation module 520 is specifically used to: determine the identification code corresponding to the emergency information; and encapsulate the identification code and the current vehicle's associated information according to a preset format to generate the notification message.

[0052] Furthermore, the receiving module 510 is specifically used to: receive emergency information input by the user through the central control screen or user terminal; or, receive emergency information input by the user through voice.
