[0018] Figure 3 This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] The following is combined with Figures 1-3 The present invention describes an electric vehicle alarm method, apparatus, electronic device, and storage medium.

[0021] Figure 1This is a flowchart illustrating the electric vehicle alarm method provided by the present invention, as shown below. Figure 1 As shown, the method includes the following steps: Step 101: When the first electric vehicle triggers the alarm state, an alarm delay is generated, and the first alarm suppression information is broadcast to each of the second electric vehicles.

[0022] It should be noted that this invention is primarily applied to shared vehicle scenarios with centralized parking, such as shared electric bikes and shared bicycles. In these scenarios, vehicles are typically deployed in batches, and users are restricted to parking in designated areas (such as commercial areas, residential areas, campuses, and corporate parks). Therefore, during operation, vehicle parking is concentrated in small areas. In the case of concentrated parking, if some vehicles accidentally tip over, it can easily create a domino effect, causing a row of vehicles to tip over, which in turn triggers the alarms of multiple surrounding vehicles simultaneously, generating significant noise and affecting nearby residents.

[0023] Each shared electric vehicle is equipped with multiple sensors, including but not limited to: wheel motion sensors: used to detect the movement of the wheels; vibration sensors: used to detect whether the vehicle is subjected to excessive external impact or vibration; attitude sensors (such as accelerometers and gyroscopes): used to detect changes in the vehicle's tilt angle and direction.

[0024] The microcontroller or embedded system in the vehicle continuously monitors the output of these sensors. When these sensors detect specific actions or sensing values ​​exceeding threshold ranges, the electric vehicle triggers an alarm. For example, with wheel movement sensors, in the locked state, if a wheel is detected rotating more than a certain angle or number of times, indicating wheel movement, it suggests a possible unauthorized attempt to move the vehicle, triggering an alarm. With vibration sensors, in the locked state, if a vibration intensity exceeding a set threshold is detected, indicating abnormally large vibrations, it suggests the vehicle may have been pushed over or impacted, triggering an alarm. With attitude sensors, in the locked state, if the vehicle is detected falling or tilting at an angle exceeding a preset value (e.g., over 45 degrees), it suggests the vehicle may have been maliciously damaged or overturned, triggering an alarm.

[0025] When the first shared electric vehicle triggers an alarm, an alarm delay is generated, and a first alarm suppression message is broadcast to all second electric vehicles. Specifically, each shared electric vehicle is equipped with a Bluetooth module. When the first electric vehicle triggers an alarm, the Bluetooth module is automatically activated, and then the first alarm suppression message is broadcast to all second electric vehicles via Bluetooth. Nearby shared electric vehicles will receive this first alarm suppression message.

[0026] In this embodiment of the invention, the first alarm suppression information will be broadcast continuously for a period of time, the specific duration of which can be set according to actual needs, such as a few seconds to tens of seconds. The first alarm suppression information includes information such as the time when the first electric vehicle triggered the alarm state, the vehicle identifier (ID), and the vehicle MAC address.

[0027] Alarm delay can be understood as delaying the alarm activation after a collision, movement, or overturning of the vehicle. Setting an alarm delay gives the vehicle time to process broadcast messages, ensuring sufficient time to process the information and attempt to resolve potential mass alarm issues before triggering the alarm.

[0028] Step 102: Receive the second alarm suppression information broadcast by at least one of the second electric vehicles.

[0029] The second electric vehicle can be understood as a vehicle parked together with the first electric vehicle, or a vehicle parked near the first electric vehicle. When the second electric vehicle triggers the alarm, an alarm delay is generated, the Bluetooth module is activated, and then a second alarm suppression information is broadcast to nearby electric vehicles via Bluetooth. This second alarm suppression information includes the time the second electric vehicle triggered the alarm, its vehicle ID, and its MAC address.

[0030] While the first electric vehicle sends the first alarm suppression information to the surrounding second electric vehicles, it is also listening to the surrounding Bluetooth signals to receive the second alarm suppression information broadcast by at least one second electric vehicle based on the Bluetooth module.

[0031] Under normal circumstances, a vehicle's Bluetooth is in a state of periodic wake-up and event wake-up. Unless specific services are being performed, Bluetooth is mainly in sleep mode to reduce power consumption. In this embodiment of the invention, triggering an alarm is one way to wake up Bluetooth. For vehicles that do not trigger an alarm, their Bluetooth will not be activated; they will neither send alarm suppression information nor receive related information. Therefore, those vehicles that are actually involved in information broadcasting and receiving are those whose alarms are triggered within a relatively short period of time.

[0032] Step 103: If the number of second alarm suppression messages sent from different second electric vehicles is greater than the set threshold, then the alarm sound is suppressed.

[0033] After receiving the second alarm suppression information sent by other vehicles, the address information of the second electric vehicle carried by the second alarm suppression information is obtained. Then, the second alarm suppression information is classified according to the address information of the second electric vehicle. Finally, the number of second alarm suppression information sent from different second electric vehicles is determined according to the classification results.

[0034] For example, after receiving alarm suppression information from other vehicles, the first electric vehicle categorizes these alarm suppression messages based on the MAC addresses carried within them. The MAC address is a unique identifier for the device, allowing the first electric vehicle to identify that each alarm suppression message originates from a different vehicle. When a new alarm suppression message (i.e., a new MAC address) is received, the counter is incremented by 1. For instance, assuming vehicle A receives alarm suppression messages from vehicles B, C, and D, vehicle A has recorded receiving three alarm suppression messages from different sources (i.e., different MAC addresses).

[0035] It is understandable that, since the second alarm suppression information will be continuously sent for a period of time, the first electric vehicle can receive multiple alarm suppression information sent by the same second electric vehicle. However, since these alarm suppression information carry the same MAC address, they are only counted once.

[0036] Determine whether the number of second alarm suppression messages received from different second electric vehicles is greater than a set threshold. If it is greater than the set threshold, it indicates that a large number of vehicles are alarming at once. In this case, in order to reduce noise interference to surrounding residents or pedestrians, the alarm sound needs to be suppressed.

[0037] Step 104: When the alarm delay is reached at the current time, a suppressed alarm sound is emitted.

[0038] If the current time reaches the alarm delay, a suppressed alarm sound will be emitted.

[0039] In one embodiment, in the event of a large-scale alarm event, the vehicle that first triggered the alarm can be identified. This vehicle then continues to issue an alarm, while other vehicles, upon receiving alarm suppression information, will silence their alarms, thus avoiding interference from multiple alarms. The specific implementation is as follows: If the number of alarms exceeds a set threshold, the timestamps of the first and second electric vehicles triggering their alarm states are obtained. If the first electric vehicle's alarm trigger time is earlier than the second, the current alarm continues; if the first electric vehicle's alarm trigger time is later than the second, the current alarm is canceled. For example, suppose vehicle A receives alarm suppression information from 5 other vehicles (with a set threshold of 2). This indicates a large-scale concentrated alarm event. Simultaneously, vehicle A compares the timestamps in these received alarm suppression messages with its own alarm trigger time. If the time in the alarm suppression information received by vehicle A is earlier than its own alarm trigger time, it means another vehicle triggered its alarm before vehicle A, and vehicle A's alarm may have been influenced by other vehicles. In this case, vehicle A will cancel its current alarm and enter silent mode to avoid multiple vehicles simultaneously triggering alarms in the same event. If the time in the received alarm suppression information is later than the time when vehicle A itself triggered the alarm, it means that vehicle A's alarm was triggered earlier than the alarms triggered by other vehicles. Therefore, vehicle A will continue to issue the current alarm and will not be affected by other vehicles.

[0040] This invention enables vehicles to coordinate with each other, avoiding the generation of numerous repeated alarm sounds in the same event, thereby reducing interference to the surrounding environment and residents.

[0041] The electric vehicle alarm method provided by this invention generates an alarm delay when the first electric vehicle triggers an alarm, and broadcasts first alarm suppression information to each second electric vehicle; receives second alarm suppression information broadcast by at least one second electric vehicle; if the number of second alarm suppression messages sent from different second electric vehicles exceeds a set threshold, the alarm sound is suppressed; and when the alarm delay is reached at the current time, the suppressed alarm sound is emitted. This invention determines whether a large-scale concentrated alarm situation has occurred based on the number of second alarm suppression messages received from different second electric vehicles. In the case of a batch alarm, the response of most vehicles can be suppressed, thereby reducing noise interference to surrounding residents or pedestrians.

[0042] Based on the above embodiments, the alarm sound is suppressed in the following manner: Step 111: Determine the suppression measures for the alarm sound based on the number of second alarm suppression messages sent from different second electric vehicles; Step 112: Suppress the alarm sound according to the suppression measures.

[0043] Based on the count of received alarm suppression information, measures to suppress alarm sounds can be determined. These measures include silent alarms and reduced alarm volume. A silent alarm means that no sound is emitted; instead, visual signals (such as flashing alarm indicator lights) are used to indicate abnormalities. Reduced alarm volume involves lowering the alarm volume by one or more levels to reduce noise interference.

[0044] For example, the level of measures to be taken can be determined based on the count of received alarm suppression information. Typically, different thresholds and corresponding measure levels can be preset to implement different suppression measures depending on the situation. For example, Level 1: Alarm suppression information count X, 2 ≤ X < 5, indicates a localized alarm event; the corresponding suppression measure is to moderately reduce the alarm volume. Level 2: Alarm suppression information count X, 5 ≤ X < 10, indicates a large-area concentrated alarm event; to avoid noise interference, the corresponding suppression measure is to significantly reduce the alarm volume or use a silent alarm. Level 3: Alarm suppression information count X, X ≥ 10, indicates a serious concentrated alarm event; to avoid noise interference, the corresponding suppression measure is to use a silent alarm.

[0045] If the suppression measure is a silent alarm, the alarm sound is turned off. If the suppression measure is a volume reduction alarm, the alarm volume level is reduced. For example, the current volume level is reduced by at least one level, and the reduction can be adjusted according to actual needs; then, the new volume level is recorded in the original alarm information, and the alarm is issued at this lower volume.

[0046] In one embodiment, assume multiple shared electric vehicles detect anomalies almost simultaneously in the same area. To avoid noise pollution caused by simultaneous high-volume alarms, one vehicle can be assigned to sound an alarm at a normal volume based on factors such as priority and timestamps, while the others can choose to sound an alarm silently or at a reduced volume. For example, the vehicle that detects the anomaly first sounds an alarm at a normal volume, while other vehicles, after receiving alarm suppression information, choose to sound an alarm silently, using the flashing frequency and duration of indicator lights to indicate the anomaly. Alternatively, other vehicles can sound alarms at a reduced volume, ensuring that the overall ambient noise is not excessive while still guaranteeing that the anomaly detection of each vehicle is noticeable.

[0047] In one embodiment, the alarm method can also be a frequency-converting sound alarm and a frequency-reducing sound alarm. A frequency-converting sound alarm uses different frequencies of sound (e.g., alternating high and low frequencies) to attract attention, while a frequency-reducing sound alarm refers to reducing the alarm frequency of the alarm sound.

[0048] In one embodiment, when using a silent alarm, if the current time reaches the alarm delay, the alarm sound is muted, and the alarm indicator light is controlled to flash at a set flashing frequency and for a set flashing duration. The flashing frequency of the alarm indicator light can represent different alarm levels or urgency; for example, rapid flashing indicates a more urgent situation, while slow flashing indicates a normal alarm. The flashing duration can also convey the continuity and importance of the alarm; for example, a long flash indicates an issue requiring continuous attention.

[0049] This invention determines alarm suppression measures based on the count of received alarm suppression information, so that in the event of a batch of alarms, the response of most vehicles can be suppressed, thereby reducing noise interference to surrounding residents or pedestrians.

[0050] Based on the above embodiments, the alarm volume level is determined in the following way: Step 121: Collect the noise level of the surrounding environment; Step 122: Determine the alarm volume level based on the noise level.

[0051] The vehicle periodically collects ambient noise levels and then determines the alarm volume level based on the noise level. For example, the alarm volume level can be set to four levels: silent, low, medium, and high.

[0052] 1) When the ambient noise exceeds 60 dB, the alarm volume level is set to high. This is because a stronger alarm volume is needed to ensure that the alarm is heard in high ambient noise conditions.

[0053] 2) When the ambient noise is between 40-60dB, the alarm volume level should be set to medium.

[0054] 3) When the ambient noise level is below 30dB, the alarm volume level is set to low. This prevents the alarm from being too loud in quiet environments.

[0055] In one embodiment, the vehicle alarm volume can be adjusted based on ambient noise to ensure alarm effectiveness while minimizing impact on the surrounding environment and residents. If further reduction of the alarm's impact on nearby residents is needed, the volume can be lowered by adjusting it down at least one level from the base volume setting. For example, if the base volume is set high, it can be lowered to medium. If the base volume is set medium, it can be lowered to low. If the base volume is set low, it may be muted or kept at a low volume. In this way, the alarm volume can be dynamically adjusted according to the actual ambient noise, ensuring the alarm remains effective in noisy environments while minimizing noise interference to nearby residents or pedestrians in quiet environments.

[0056] Assuming the vehicle is parked in a quiet residential area with an ambient noise level of 25dB, the alarm volume will be set to low according to this plan. To further reduce the impact, the alarm volume can be lowered another level, potentially approaching silence. Conversely, if the vehicle is parked in a busy city center with an ambient noise level of 70dB, the alarm volume will be set to high to ensure the alarm is still audible in noisy environments.

[0057] The embodiments of the present invention can achieve intelligent control of alarm sound through an alarm volume adjustment mechanism based on environmental noise, which not only ensures the effectiveness of the alarm sound, but also minimizes noise interference to surrounding residents or pedestrians.

[0058] Based on the above embodiments, after receiving the second alarm suppression information broadcast by at least one second electric vehicle, the method further includes: Step 131: Obtain the signal strength of the second alarm suppression information; Step 132: If the signal strength is less than the set strength, discard the second alarm suppression information.

[0059] In this embodiment of the invention, the signal strength between vehicles (such as Received Signal Strength Indicator (RSSI)) can be used to determine whether the received second alarm suppression information needs to be discarded. Signal strength reflects the distance between vehicles, therefore the relative position and distance between vehicles can be inferred from the signal strength.

[0060] After receiving a second alarm suppression message from another nearby second electric vehicle, the first electric vehicle acquires the signal strength of the second alarm suppression message and compares it with a preset strength. If the signal strength is less than the preset strength, it indicates that the distance between the first and second electric vehicles is too great, and their alarm triggering may be unrelated. In this case, there is unlikely to be a tipping event affecting surrounding vehicles, so the relevant second alarm suppression message can be discarded. Conversely, when the signal strength between the two vehicles is very low, it means they are far apart, and their tipping events are not expected to affect each other, thus alarm suppression is unnecessary. Therefore, the decision to discard alarm suppression information can be dynamically made based on the received signal strength, allowing alarms to be suppressed only when truly needed, thereby more effectively managing alarm propagation and reducing unnecessary interference.

[0061] In one embodiment, suppose there is a shared electric scooter A and another shared electric scooter B, which are relatively far apart. For example, scooter A is parked in one corner of the community, while scooter B is parked in another corner. Because of the distance, their tipping events may not affect each other; even if one scooter tipps over, it won't affect the other. In this case, the Bluetooth communication between scooter A and scooter B may show a low signal strength, indicating the distance between them. When scooter A tipps over and triggers an alarm, scooter A will broadcast an alarm suppression message via its Bluetooth module. However, when this alarm suppression message reaches scooter B, due to the low signal strength between scooter A and scooter B, scooter B can determine that the two scooters are far apart and can therefore choose to discard the alarm suppression message, as scooter B is likely not affected by scooter A's tipping event.

[0062] The embodiments of the present invention help reduce false alarms by dynamically deciding whether to discard alarm suppression information based on the received signal strength, thereby reducing noise interference to surrounding residents or pedestrians.

[0063] Based on the above embodiments, after the alarm delay is reached at the current time and a suppressed alarm sound is emitted, the method further includes: Step 141: Report a collective alarm event to the server, wherein the collective alarm event includes the second alarm suppression information received by the first electric vehicle.

[0064] In this embodiment of the invention, in addition to reporting the current alarm status to the server as normal, vehicles that trigger an alarm and receive several alarm suppression messages but do not cancel the alarm will eventually report a collective alarm event.

[0065] Understandably, when a vehicle triggers an alarm, it reports its current alarm status to the server. The server records this information and processes and records the vehicle's alarm status accordingly. For vehicles that receive several alarm suppression messages but do not cancel the alarm, it indicates that the vehicle did not cancel the alarm status after receiving the suppression messages. In this case, the vehicle reports a collective alarm event to the server. The collective alarm event includes the alarm suppression messages received by this vehicle. This is done to allow the server to understand how many vehicles were affected by similar alarm suppression within the same time period, as well as the scope and severity of this impact.

[0066] The server will generate corresponding maintenance work orders based on the number of vehicles involved and the specific details of the collective alarm event. This means that the server needs to further process and track these collective alarm events, involving tasks such as on-site inspection, troubleshooting, and system optimization.

[0067] This invention, by reporting collective alarm events to the server, enables the server to gain a more comprehensive understanding of the collective alarm situation and take corresponding operational and maintenance measures for vehicle alarm management. This helps improve the reliability of vehicle alarm management and reduces noise interference to surrounding residents or pedestrians.
