In the present embodiment, the emergency trigger event may be understood as an event for triggering an emergency call, and for example, the emergency trigger event may include a vehicle fault, an abnormal state of an occupant, and the like. The vehicle faults can comprise engine faults, transmission faults, steering wheel faults and the like; abnormal conditions of the driver and the passenger can include long-time closed eyes, upper half body lying on a steering wheel, left and right side falling coma and the like. The emergency call-for-help prompt information can be understood as corresponding call-for-help prompt information generated by the vehicle-mounted terminal when an emergency trigger event is detected.

In one implementation, when an emergency trigger event is detected, a word of "SOS" is displayed on the display device, and ring warning is performed through the voice playing device. In another implementation, when an emergency trigger event is detected, the voice-playing device plays "vehicle failed, please check immediately! "," driver and passenger status is abnormal, please check immediately! And the like prompt voice.

Specifically, the vehicle-mounted terminal generates corresponding emergency call prompt information according to the detected emergency trigger event, so that a corresponding emergency strategy can be determined subsequently according to the emergency call prompt information.

And S120, determining an emergency strategy according to the response result of the driver and the passenger to the emergency call prompt information.

In this embodiment, the response result may be understood as a result of determining whether the driver and the passenger perform corresponding feedback operations after the vehicle-mounted terminal generates the emergency call prompt information. Illustratively, the response result can comprise two results of the driver and the passenger having feedback response and no feedback response. The emergency strategy can be understood as a corresponding emergency call strategy determined by the vehicle-mounted terminal after the driver and the passengers make corresponding response operation according to the emergency call prompt information. Exemplary contingency policies may include, without limitation, several: firstly, when the vehicle breaks down but the damage condition is light, for example, drivers and passengers are not injured or are slightly injured, the vehicle-mounted terminal sends out a common call signal, audio communication equipment on the vehicle is opened according to instructions of the drivers and passengers to communicate with background personnel (operators or emergency units), and the background personnel provide on-site rescue guidance; secondly, when the vehicle breaks down but the damage is serious, for example, the driver and the passengers are faint, the vehicle-mounted terminal can send an emergency call signal, and can automatically start the video call equipment and the satellite positioning equipment on the vehicle, and the background personnel provide reasonable rescue equipment according to the field condition; thirdly, when the state of the driver and the passengers is abnormal but the serious conditions such as syncope do not occur, the vehicle-mounted terminal can send out voice alarm to remind the driver and the passengers to pay attention; and fourthly, when the state of the driver and the passengers is abnormal and severe conditions such as syncope occur, the vehicle-mounted terminal can send out an emergency call signal, the video call device and the satellite positioning device on the vehicle can be automatically started, and the background personnel provide reasonable rescue equipment according to the field conditions.

Specifically, after the vehicle-mounted terminal generates the emergency call prompt information, a corresponding emergency strategy is determined according to a response result of the driver and the passenger aiming at the emergency call prompt information, so that the corresponding emergency call is conveniently executed according to the emergency strategy.

And S130, executing emergency call according to the emergency strategy.

Specifically, according to the determined emergency strategies of different levels, the vehicle-mounted terminal executes corresponding emergency call measures. Illustratively, when the vehicle-mounted terminal detects that drivers and passengers are in an abnormal state or detects the state information of the popping of the safety airbag and the conditions of shock, syncope and the like occur, the vehicle-mounted terminal triggers an emergency call mechanism, at the moment, the vehicle-mounted terminal can send an emergency call signal and automatically start a video call device and a satellite positioning device on a vehicle, and background personnel provide reasonable rescue equipment according to the field conditions.

According to the technical scheme, the emergency call prompt information is generated when the emergency trigger event is detected, the emergency strategy is determined according to the response result of the driver and the passenger to the emergency call prompt information, and then the emergency call is executed according to the emergency strategy. The embodiment of the invention solves the technical problem of single emergency strategy under emergency conditions in the prior art, realizes that the vehicle determines the corresponding emergency strategy according to different emergency trigger events, and further shortens the emergency time of drivers and conductors.

Example two

Fig. 2 is a flowchart of an emergency call-for-help method provided in the second embodiment of the present invention, which is further optimized and expanded based on the foregoing embodiment, and may be combined with various optional technical solutions in the foregoing embodiment. As shown in fig. 2, the emergency call method provided in the second embodiment specifically includes the following steps:

For example, the number of the image acquisition devices may be multiple, the installation positions may be set according to actual conditions, and full coverage of posture information recognition of drivers and passengers may be achieved, which is not limited in the embodiment of the present invention. The posture can be understood as the physical form of the driver and the passenger, and exemplarily, the posture can include the eye state, the face state, the body posture and the like of the driver and the passenger.

For example, the abnormal posture may include a driver or a passenger leaving the steering wheel with one or both hands due to coma, long head-lowering, and the like. In some embodiments, the abnormal posture may be determined comprehensively according to the biological characteristic information collected by the human body state sensor and/or the posture information of the driver and passenger collected by the image collecting device. For example, when the biometric information acquired by the human body state sensor is greatly different from the data in the normal state, the vehicle-mounted terminal may actively control the image acquisition device to acquire the posture information of the driver and passenger, and if the driver and passenger are identified to be faint from the posture information, the current posture of the driver and passenger may be determined to be an abnormal posture.

Specifically, when the biological characteristic information acquired by the human body state sensor and/or the posture information of the driver and passengers acquired by the image acquisition device are abnormal, the vehicle-mounted terminal generates corresponding emergency call prompt information.

In this embodiment, the response information may be understood as a feedback operation made by the driver and the passenger for the emergency call prompt information. Illustratively, the response information can comprise the presence or absence of corresponding feedback operation of the driver and the passenger for the emergency call prompt information. In some embodiments, after the driver and the passenger receive the emergency call prompt information played by the voice playing device, if the awareness state of the driver and the passenger is good at the moment, the driver and the passenger can actively close the voice playing device and feed back the voice playing device to the voice collecting device, for example, a vehicle-mounted terminal controls the voice playing device in the vehicle to play the voice of 'alarm release'; if the consciousness state of the driver and the passenger is poor and the driver and the passenger have the activity ability, the voice acquisition equipment can be actively started to actively call; if the driver and the passenger completely lose consciousness and activity ability, such as shock, syncope and the like, the voice acquisition equipment cannot acquire any feedback operation of the driver and the passenger.

Specifically, after the voice playing device plays the emergency call prompt message, the vehicle-mounted terminal detects whether the voice collecting device collects the response message of the driver and the crew, so as to determine a corresponding emergency strategy according to different response results.

And S250, determining the emergency strategy as a first-level emergency strategy under the condition that the response result is that the response information is collected.

Fig. 3 is a flowchart of an emergency call-for-help method according to a third embodiment of the present invention. In the present embodiment, in addition to the above-described embodiments, the vehicle-mounted terminal is taken as a TBOX system as an example, and a process of emergency call is described. As shown in fig. 3, an emergency call method provided in the third embodiment of the present invention specifically includes the following steps:

Fig. 4 shows a flow chart for judging whether the state of the driver and the passenger is abnormal according to the human body state sensor and the camera in the vehicle.

Specifically, the SOC (System on Chip) operation module may pre-store the biometric information of the common drivers and conductors in the normal state. Furthermore, after receiving the real-time state data processed by the human body state sensor through the sensor data processing module, the SOC operation module can be further used for comparing the real-time state data with the pre-stored normal state data and judging whether the real-time state data of the driver and the passenger is abnormal. Furthermore, when a large difference exists between the real-time state data and the normal state data, the SOC operation module can also analyze the video data processed by the video processing module of the camera in the vehicle, recognize the real-time posture of the driver and the passenger through a built-in image recognition algorithm, and accurately judge the real-time state of the driver and the passenger by combining the comparison result of the real-time state data.

S330, judging whether the driver and the crew are in a shock or faint state, if so, sending an emergency call by the emergency call device, and turning on a video; otherwise, the emergency call device controls the loudspeaker to send out voice alarm reminding.

Specifically, when the driver and the passenger are judged to be in abnormal states such as shock and faint states, the TBOX system immediately sends out an emergency call, forcibly turns on the inside/outside camera of the vehicle, uploads information such as a field picture and a vehicle position shot by the inside/outside camera of the vehicle to the cloud emergency platform, the information is analyzed and processed by the cloud emergency platform, and finally corresponding emergency equipment such as a rescue water boat and a rescue helicopter is configured according to the field states; when the driver and the crew are judged not to be in abnormal states such as shock, faint state and the like, the emergency call-for-help device can control the loudspeaker to give out voice alarm reminding.

As shown in fig. 5, another emergency call method provided in the third embodiment of the present invention specifically includes the following steps:

When the voltage of the standby battery is less than or equal to 4V, the standby battery is charged by the automobile power supply; and when the automobile power supply voltage is less than or equal to 4.5 volts, switching the standby battery to supply power to the whole TBOX system.

In some embodiments, an encryption algorithm can be further arranged on the SOC operation module and the wireless communication module to realize double encryption, so that the security of the TBOX system is improved. For example, the normal state data of the driver and passenger collected by the human body state sensor may be encrypted and stored in the SOC operation module as the historical state data. Illustratively, the encryption algorithm may include a symmetric encryption algorithm, an asymmetric encryption algorithm, and the like.

According to the technical scheme of the embodiment, when drivers and passengers are in the vehicle, the human body state sensor acquires state data of the drivers and passengers in real time; comparing the acquired real-time state data of the drivers and passengers with corresponding state data in a normal state, acquiring attitude data of the drivers and passengers by matching with a camera, and comprehensively judging whether the states of the drivers and passengers are abnormal or not; and triggering emergency call or voice alarm reminding according to the state of the driver and the passengers. According to the technical scheme of the embodiment, CAN bus signals are collected in real time through the CAN controller, and early warning is sent out according to different states; and when the common early warning signal is received, the voice communication equipment is opened to communicate with background personnel and guide on-site rescue according to the instructions of the drivers and conductors. When the emergency call signal is received, the human body sensor is matched with the camera in the vehicle to judge the state of the driver and the passengers, the audio and the video are actively turned on to be processed in the background, and the background personnel provide corresponding emergency equipment according to the field state.
