[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0034] In the present application, the terms "comprises", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, article or device including the element.

[0035] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0036] In related technologies, vehicles can send out distress messages based on Bluetooth, and rescuers can find the vehicle seeking help through the relay principle of Bluetooth and the strength of the signal.

[0037] However, in the above method, the Bluetooth communication relay will only have a better effect when there are many Bluetooth devices. If there is no relay, it can only be searched within the Bluetooth communication range, and the search distance is only 10-100 meters, and the rescue range is small.

[0038] Moreover, this method only has the function of searching for vehicles, and its function is relatively simple.

[0039] In the related technology, a satellite phone can also be dialed to ask for help, and rescuers can find the rescue vehicle through positioning satellites.

[0040] For example, Figure 1 Figure 1 is a schematic diagram of a satellite-based rescue method. Figure 1 As shown, the rescue vehicle 101 can establish a connection with the satellite 102 through the satellite communication link 106, and then send a signal to the communication satellite system control center 103 through the satellite communication link 107, and the communication satellite system control center 103 sends the rescue information to the rescue center 105 through the wired link 108. At the same time, the Beidou positioning satellite 104 can obtain the position of the rescue vehicle 101 through the Beidou short message link 109, and send the position of the rescue vehicle 101 to the rescue center 105 through the Beidou short message link 1010, and then the rescue center 105 can rescue the vehicle 101 based on the rescue information of the rescue vehicle 101 and the position of the rescue vehicle 101.

[0041] For example, Figure 2 The schematic diagram of the structure of the module used for satellite distress in the vehicle is shown in FIG. Figure 2 As shown, the module includes a Beidou positioning system module, a remote communication control unit, an intelligent vehicle terminal, a mobile network module and a satellite communication module.

[0042] Among them, the Beidou positioning system module, the remote communication control unit, the mobile network module and the satellite communication module are respectively connected to the intelligent vehicle terminal. Based on the intelligent vehicle terminal, the user can call the function of the Beidou positioning system module to obtain the location of the vehicle, call the function of the remote communication control unit for remote communication, call the function of the mobile network module to realize mobile network communication, and call the function of the satellite communication module for satellite communication.

[0043] However, in this method, in areas such as tunnels, mountainous areas, hilly areas, and buildings, the signals of communication satellites and Beidou positioning satellites are poor, and the satellite phone may not work properly and cannot obtain the location of the vehicle. In addition, satellite phones are expensive. If the vehicle does not need rescue, the cost of using satellite phone communication is very high.

[0044] In the related art, a vehicle can be equipped with a car intercom to make voice calls based on the car intercom. However, the existing car intercom usually needs to be equipped with a microphone for calls. In addition, when the specific location of the vehicle is unknown, even if the rescue is successful through the car intercom, the rescue personnel cannot know the location of the vehicle.

[0045] As described in the background art, satellite signals are weak in areas such as tunnels and buildings. When a vehicle is located in such areas, rescuers may not be able to accurately locate the vehicle.

[0046] Based on the technical problems existing in the above-mentioned related technologies, the present application provides a communication method, an electronic device and a storage medium. The current accurate position of the vehicle can be determined based on the last positioning signal before the positioning signal disappears and the driving trajectory of the vehicle, and then based on the preset frequency band of the walkie-talkie system, a first request message including the current position of the vehicle is sent. The accurate current position of the vehicle can be sent to other devices and vehicles using the preset frequency band, so that other people can obtain the accurate position of the vehicle even in areas with weak satellite signals.

[0047] Furthermore, since the preset frequency band is a preset frequency band of the intercom system, the first request message sent based on the preset frequency band has a larger range and a longer distance.

[0048] The communication method provided in the embodiment of the present application is described below by taking an electronic device as an example of an execution subject of the communication method provided in the embodiment of the present application.

[0049] like Figure 3 As shown, the communication method includes S301-S302.

[0050] S301. Determine the current position information of the vehicle based on the last positioning information of the vehicle before the positioning signal disappears and the driving track of the vehicle.

[0051] It should be understood that the driving trajectory of the vehicle is the driving trajectory of the vehicle starting from the moment the positioning signal disappears.

[0052] It can be understood that the last positioning information is the positioning information included in the positioning signal, which is the longitude and latitude information, and the current position information of the vehicle determined based on this is also the longitude and latitude information.

[0053] Optionally, the positioning signal may be a positioning signal of a global positioning system (GPS) or a positioning signal of a Beidou positioning system.

[0054] In an optional implementation, the vehicle may include a physical button or electronic control for calling for help. In response to the activation of the physical button or electronic control, the current location information of the vehicle can be determined based on the last positioning information of the vehicle before the positioning signal disappears and the driving trajectory of the vehicle.

[0055] In another optional implementation, when a braking failure of the vehicle is detected or someone in the vehicle is injured, the current location information of the vehicle can be determined based on the last positioning information of the vehicle before the positioning signal disappears and the driving trajectory of the vehicle.

[0056] Optionally, image recognition may be performed on the image captured by the camera, and whether anyone is injured may be determined based on the recognition structure.

[0057] S302: Send a first request message based on a preset frequency band.

[0058] The first request message includes the current location information, and the preset frequency band is a frequency band preset in the intercom system.

[0059] It should be understood that the intercom system is an intercom system configured in a vehicle, the intercom system has the function of an intercom, and the intercom system includes a preset frequency band.

[0060] It is understandable that the frequency bands preset in the intercom system are all relatively low frequency bands, and the transmission distance of sending the first request message based on the preset frequency band is relatively long and the coverage area is relatively large. Therefore, the current location information of the vehicle can be transmitted to a farther distance, thereby increasing the range of signal reception and the number of devices receiving the signal, thereby increasing the rescue success rate.

[0061] Optionally, the preset frequency band may be 136-174 MHz, 600-490 MHz.

[0062] In an optional implementation manner, the first request message may be sent periodically based on a preset frequency and based on the preset frequency band.

[0063] Optionally, the first request message may also include at least one of the following: the driving trajectory of the vehicle, the last positioning information of the vehicle, the cause of the vehicle's failure, the number of times the first request message is sent, the sending time of the first request message, and the vehicle status of the vehicle.

[0064] It should be understood that the status of the vehicle is used to characterize whether the vehicle has a fault. In the event of a fault in the vehicle, the first request message includes the cause of the fault so that rescue personnel can carry corresponding tools to carry out rescue based on the cause of the fault.

[0065] Optionally, the first request message may also include a message header, a message length, a check code, a packet tail, a signal identifier, etc.

[0066] Table 1 is an example of a first request message.

[0067] Table 1

[0068]

[0069] Exemplarily, as shown in Table 1, the first request message includes a message header, a message length, a vehicle status, a fault cause, the last positioning information, a driving track, a time for asking for help, a signal identifier, a check code, and a packet tail.

[0070] In an optional implementation, at least one of the following may also be displayed: the driving track of the vehicle, the last positioning information of the vehicle, the cause of the vehicle's failure, the number of times the first request message is sent, the sending time of the first request message, and the vehicle status of the vehicle.

[0071] Optionally, the above information can be displayed on a display screen of the vehicle, so that the user can describe the above information to rescuers based on the content on the display screen.

[0072] Optionally, the display screen may be a central control screen, instrument display, etc. of the vehicle.

[0073] In one implementation of the embodiment of the present application, the above information may also be stored, and the information may be updated based on a preset period, so that the vehicle's driving record may be subsequently queried based on the information.

[0074] Exemplarily, the preset period may be 7 days.

[0075] In an embodiment of the present application, the vehicle's current accurate position can be determined based on the last positioning signal before the positioning signal disappears and the vehicle's driving trajectory, and then a first request message including the vehicle's current position is sent based on the preset frequency band of the walkie-talkie system. The vehicle's accurate current position can be sent to other devices and vehicles using the preset frequency band, so that other people can obtain the vehicle's accurate position.

[0076] Combination Figure 3 ,like Figure 4 As shown, in one implementation of the embodiment of the present application, before determining the current position information of the vehicle based on the last positioning information of the vehicle and the driving trajectory of the vehicle, the communication method also includes S401-S402.

[0077] S401. In response to the disappearance of the vehicle positioning signal, determine the last positioning information and collect the vehicle driving information.

[0078] The driving information includes steering wheel angle, driving speed and driving time.

[0079] It should be understood that when the vehicle cannot receive the positioning signal, it can be determined that the positioning signal disappears. At this time, the last positioning information can be determined and the vehicle's driving information can be collected.

[0080] Specifically, the vehicle's current steering wheel angle and the driving speed and driving time based on the steering wheel angle are collected, as well as the driving speed and driving time based on each steering wheel angle after the steering wheel angle changes.

[0081] S402: Determine a driving trajectory of the vehicle based on driving information.

[0082] It should be understood that based on the relationship between the steering wheel angle and the wheel angle, the relative position of the vehicle with respect to the last positioning information can be determined.

[0083] Specifically, based on each change in the steering wheel angle, the driving speed, and the driving time, multiple relative displacements and multiple position points can be determined, and the driving trajectory can be obtained based on the multiple position points.

[0084] For example, Figure 5 is a schematic diagram of a vehicle's driving trajectory. Figure 5 As shown, the Figure 5 The last positioning information and multiple location points are included.

[0085] Figure 6 is a schematic diagram of another vehicle's driving trajectory. Figure 5 ,like Figure 6 As shown, Figure 6 The last positioning information and multiple position points are also included in the data. By connecting the last positioning information and the multiple position points, the driving trajectory of the vehicle can be obtained.

[0086] In an optional implementation, the multiple position points and each relative displacement may also be stored.

[0087] In the embodiment of the present application, the driving trajectory of the vehicle can be accurately determined based on the last positioning information of the vehicle and the steering wheel angle, driving speed, and driving time.

[0088] It is understandable that multiple frequency bands may be preset in the intercom system, including a broadcast frequency band corresponding to the broadcast mode, a multicast frequency band corresponding to the multicast mode, and a unicast frequency band corresponding to the unicast mode.

[0089] In an implementation manner of the embodiment of the present application, the preset frequency band may be a preset broadcast frequency band in the intercom system, and the sending of the first request message based on the preset frequency band may specifically be: broadcasting the first request message based on the preset frequency band.

[0090] It should be understood that in the broadcast mode, any device using the broadcast frequency band, including the vehicle's intercom system and other handheld intercoms, can receive the first request message.

[0091] Optionally, the broadcast frequency band may be set as a default frequency band, and in response to a malfunction in the vehicle or an injury to a person, the first request message may be broadcast based on the broadcast frequency band by default.

[0092] It can be understood that when the preset frequency band is a broadcast frequency band, the first request message is broadcast based on the preset frequency band, and all devices using the broadcast frequency band can receive the first request message, which can increase the probability of finding the first request message and improve the success rate of rescue.

[0093] It should be understood that the communication method can also be applied to the application scenario of inter-vehicle communication when a vehicle fleet travels in a team. By sending the first request message to other vehicles in the vehicle fleet, the other vehicles can learn the current location information of the vehicle.

[0094] In one implementation of an embodiment of the present application, the above-mentioned preset frequency band is a communication frequency band of paired devices preset in the walkie-talkie system, and the above-mentioned sending of the first request message based on the preset frequency band can specifically be: sending a first request message to the paired device based on the preset frequency band.

[0095] It can be understood that when there is only one paired device, the preset frequency band is a unicast frequency band, and when there are multiple paired devices, the preset frequency band is a multicast frequency band.

[0096] It should be understood that before sending the first request message to the paired device based on the preset frequency band, it is necessary to first pair with multiple devices in the preset multicast frequency band, or pair with one device in the unicast frequency band, and then communicate with the paired device based on the multicast frequency band or unicast frequency band, for example, send the first request message to the paired device.

[0097] Optionally, based on the multicast frequency band or the unicast frequency band, voice communication can also be performed with a paired device.

[0098] In an optional implementation, the intercom system includes a microphone, a talk button and a mode button. In response to a mode selection operation and a start operation of the talk button, the microphone can receive a voice signal, convert the voice signal into an electrical signal, and send the electrical signal through a wire.

[0099] Optionally, in the communication mode, the user can also select a listen-only mode, a conversation mode, a shielding mode, etc. based on the mode button.

[0100] Optionally, when the user selects the listen-only mode, the user can receive voice messages from other paired devices without delivering his own voice messages.

[0101] Optionally, when the user selects the conversation mode, the user and the paired device receive each other's voice messages.

[0102] Optionally, when the user selects the blocking mode, the user cannot receive voice messages from the paired device.

[0103] It should be understood that by sending the first request message to the paired device based on the preset frequency band, the location information of the paired device can be mutually known, and then the paired device can rescue the vehicle.

[0104] In addition, since the paired devices know each other's location information, when any paired device needs a satellite phone to call for help, it can use the satellite phone of other paired devices to call for help. That is, only one of the paired devices needs to make a satellite call, which reduces the cost of using satellite phones.

[0105] It is understandable that the intercom system can also receive messages sent by other intercom systems in a preset frequency band. At this time, without the need to parse the message, the relay mode can be used to transmit the message to a farther range.

[0106] Combination Figure 3 ,like Figure 7 As shown, in one implementation of the embodiment of the present application, the communication method also includes S701.

[0107] S701. When receiving a second request message sent by another vehicle, broadcast the second request message.

[0108] It should be understood that the second request message includes the current location information of the other vehicle, as well as the driving trajectory of the other vehicle, the last positioning information of the other vehicle, the cause of the failure of the other vehicle, the number of times the second request message is sent, the sending time of the second request message, and at least one of the vehicle status of the other vehicle.

[0109] It should be understood that after the vehicle receives the second request message, it can broadcast the second request message based on the broadcast frequency band, so that other vehicles within the broadcast range can receive the second request message based on the broadcast frequency band, thereby increasing the propagation range of the second request message.

[0110] For example, Figure 8 A schematic diagram of a method for broadcasting a second request message.

[0111] like Figure 8 As shown, the vehicle 801 can send a second request message, and the vehicle 802 is a vehicle that can receive the second request message. After receiving the second request message, the vehicle 802 can broadcast the second request message so that the vehicle 803 can receive the second request message.

[0112] In one implementation of the embodiment of the present application, the transmission power of the first request message is related to the remaining power of the battery. Figure 3 ,like Fig. 9As shown, the above-mentioned sending of the first request message based on the preset frequency band specifically includes S901-S902.

[0113] S901. Determine a transmission power of a first request message based on a remaining battery power.

[0114] It should be understood that the remaining power of the battery is directly proportional to the transmission power.

[0115] Optionally, the battery is a small battery in the vehicle that powers the intercom system.

[0116] Exemplarily, the battery may be a 12-volt storage battery, which may obtain power from a vehicle's power battery, solar energy, an external power bank, or the like.

[0117] S902: Send a first request message based on a preset frequency band and transmit power.

[0118] In an optional implementation manner, the transmission range and distance may also be determined based on the transmission power, and then the first request message may be sent within the transmission range and distance based on the preset frequency band.

[0119] It is understandable that, as the remaining power varies, the transmission power of the first request message is adjusted, and then the first request message is transmitted based on the preset frequency band and transmission power, which can improve the flexibility and rationality of the transmission range of the first request message. When the battery power is low, the range of message transmission is reduced and the duration of message transmission is increased.

[0120] It should be understood that, when a signal can be received, communication can be performed using mobile communication technology, satellite, etc. In one implementation of the embodiment of the present application, a communication mode can also be determined based on the received signal strength, and then communication is performed based on the determined communication mode.

[0121] The communication method is mobile communication technology communication, satellite communication or intercom system communication.

[0122] It should be understood that the mobile communication technology includes the 4th generation mobile communication technology (4G) and the 5th generation mobile communication technology (5G), etc.

[0123] It should be understood that when the signal strength of the 5G signal is greater than the signal strength threshold, communication can be preferentially performed based on the 5G signal.

[0124] It can be understood that when the signal strength of the 5G signal is less than or equal to the signal strength threshold, and the signal strength of the 4G signal is greater than the signal strength threshold, communication can be performed based on the 4G signal.

[0125] Exemplarily, the signal strength may be -100 dBm.

[0126] It should be understood that in the absence of 4G signals and 5G signals, communication can be based on satellite signals or walkie-talkie systems.

[0127] Optionally, satellite calling can be performed based on the user's satellite communication operation.

[0128] Optionally, based on the user's startup operation on the intercom system, voice communication can be performed or a request message can be sent based on the intercom system.

[0129] In an optional implementation, even when there is no satellite signal, communication can be performed based on the walkie-talkie system.

[0130] In the embodiments of the present application, based on the signal strength, communication can be based on 4G communication, 5G communication, satellite communication or walkie-talkie system communication, and communication can be carried out at short distances and long distances, thereby improving the continuity of communication.

[0131] In one implementation of the embodiment of the present application, the execution subject of the communication method provided in the embodiment of the present application may be an electronic device. The electronic device may include a 4G\5G communication module, a satellite communication module, and a walkie-talkie communication module.

[0132] Among them, the 4G\5G communication module is used to perform 4G communication when there is a 4G signal, or to perform 5G communication when there is a 5G signal.

[0133] The satellite communication module is used for satellite communication when there is no 4G signal or 5G signal but there is a satellite signal.

[0134] The intercom communication module is used to send request messages and communicate between paired devices.

[0135] Optionally, the electronic device may also include a communication interface, based on which it can communicate with other controllers in the vehicle, and then obtain vehicle status, fault cause, driving speed, steering wheel angle, driving time, small battery power and power battery power from other controllers.

[0136] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method. In order to achieve the above functions, the internal short circuit risk identification device of the battery includes a hardware structure and / or software module corresponding to the execution of each function. It should be easy for those skilled in the art to realize that, in combination with the units and algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0137] The embodiment of the present application can divide the functional modules of the communication device according to the above method. For example, the communication device can include various functional modules corresponding to the various functional divisions, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical functional division. There may be other division methods in actual implementation.

[0138] Fig.10 A possible structural diagram of the communication device involved in the above embodiment is shown. Fig.10 The communication device 100 includes: a determining unit 1001 and a sending unit 1002.

[0139] The determination unit 1001 is used to determine the current position information of the vehicle based on the last positioning information of the vehicle before the positioning signal disappears and the driving track of the vehicle.

[0140] The sending unit 1002 is used to send a first request message based on a preset frequency band, where the first request message includes the current location information. The preset frequency band is a frequency band preset in the intercom system.
