[0024] Combine the following Figure 1-Figure 2 The abnormal awakening system of the utility model is described.

[0025] The utility model embodiment provides an abnormal awakening system, such as Figure 1 and Figure 2 As shown, the abnormal wake-up system includes a voiceprint alarm module 10, a microprocessor 20 and a camera 30. The voiceprint alarm module 10 can collect environmental sounds and generate an alarm signal. The microprocessor 20 is communicated with the voiceprint alarm module 10. The microprocessor 20 controls the camera 30 to turn on according to the alarm signal.

[0026] Cameras 30 are arranged at different positions around the vehicle, and a complete image of each position of the vehicle is obtained with the help of multiple cameras 30. There are relatively concentrated abnormal situations around the vehicle, such as the whistling sound of air when a person approaches or a foreign object approaches quickly. With the help of the voiceprint alarm module 10, the environmental sound around the vehicle can be analyzed, and an alarm signal is issued when an abnormal situation occurs. The voiceprint alarm module 10 includes a sound pickup unit and a processing unit. The sound pickup unit picks up the environmental sound around the vehicle. The processing unit extracts voiceprint feature information from the environmental sound picked up by the sound pickup unit, and compares the voiceprint feature information with the pre-stored voiceprint feature sample information. If they are consistent, it means that there are dangerous factors that need to be paid attention to in the surrounding environment. Therefore, the processing unit generates an alarm signal, and the microprocessor 20 controls the camera 30 to turn on according to the alarm signal. When there is no abnormality in the surrounding environment, the camera 30 is in a dormant state or a closed state to reduce energy consumption. Among them, the sound pickup unit is a microphone arranged on the vehicle, and the processing unit is a chip with analysis and processing capabilities.

[0027] Optionally, the voiceprint alarm module 10 is a STM32F405 chip, which has a voiceprint recognition algorithm inside and will wake up the microprocessor 20 after identifying an abnormal sound.

[0028] Typically, at least four cameras 30 are arranged around the vehicle. Taking four cameras 30 as an example, the four cameras 30 are respectively located at the left front, left rear, right front and right rear of the vehicle. In one embodiment, when the microcontroller controls the camera 30 to turn on, it can control some cameras 30 to turn on with the help of the source of the abnormal voiceprint to reduce the energy consumption of the camera 30. In another embodiment, the microcontroller controls the camera 30 to operate with a first pixel. If an abnormality is found, the camera 30 is controlled to operate with a second pixel higher than the first pixel; if no abnormality is found, the camera 30 is controlled to sleep. Thus, the camera 30 first runs at a low pixel and then at a high pixel to reduce energy consumption. Of course, the microcontroller can also control the camera 30 to run directly at a high pixel to ensure that a clear image of the abnormal situation can be captured at the first time. In yet another embodiment, if Figure 1 As shown, the camera 30 includes a low-resolution camera 31 and a high-resolution camera 32, and the microprocessor 20 controls the operation of the low-resolution camera 31 and the high-resolution camera 32 according to the recognition result of the voiceprint alarm module 10. Specifically, when the voiceprint alarm module 10 recognizes an abnormal sound, the microprocessor 20 first controls the low-resolution camera 31 to start, and if an abnormality is found, the microprocessor 20 controls the high-resolution camera 32 to start; if no abnormality is found, the high-resolution camera 32 is controlled to be always in a closed state and the low-resolution camera 31 is controlled to be closed, thereby reducing the energy consumption of the camera 30.

[0029] The abnormal awakening system provided by the embodiment of the utility model includes a voiceprint alarm module 10, which can monitor abnormal sounds around the vehicle and wake up the camera 30 before an actual collision occurs. The abnormal response speed is fast, and the voiceprint monitoring has low energy consumption, which can reduce the power consumption of the entire vehicle and extend the power supply time of the battery in the vehicle.

[0030] like Figure 1 As shown, the microprocessor 20 includes a microcontroller chip 21 and an autonomous driving chip 22. Optionally, the autonomous driving chip 22 is an A1000 chip, and the microcontroller chip 21 is a TC377 chip. Specifically, after the voiceprint alarm module 10 recognizes an abnormal sound, it will wake up the TC377 chip, and the TC377 chip will initialize the A1000 chip. The A1000 chip receives the image captured by the external camera 30, and performs image recognition and video recording.

[0031] Multiple cameras 30 are connected to the autopilot chip 22 in the microprocessor 20 through a serializer 50. The serializer 50 is used to encode the video data captured by the camera 30 into a digital signal and transmit it to the microprocessor 20. Optionally, the serializer 50 is a Max96722 chip. In the case where the camera 30 includes a low-resolution camera 31 and a high-resolution camera 32, the serializer 50 includes a Max96722 chip and a Max9288 chip. The low-resolution camera 31 is connected to the microprocessor 20 via the Max9288 chip. The high-resolution camera 32 is connected to the microprocessor 20 via the Max96722 chip.

[0032] The abnormal awakening system further includes a collision sensor 40 , and the microprocessor 20 controls the operation of the camera 30 according to an output signal of the collision sensor 40 .

[0033] Optionally, the collision sensor 40 is a mechanical collision sensor. When an object hits the collision sensor 40, the mechanical structure in the collision sensor 40 will be compressed or bent, thereby triggering a trigger switch in the collision sensor 40 to send a trigger signal, and the microprocessor 20 controls the working state of the camera 30 according to the trigger signal sent by the collision sensor 40. Of course, the collision sensor can also be a laser collision sensor or a sonic collision sensor.

[0034] In addition, the collision sensor 40 can also be a gyroscope. For example, the collision sensor 40 is ASM3300LHH. When the collision sensor 40 is vibrated, the TC377 chip in the microprocessor 20 is awakened, and then the TC377 chip initializes the A1000 chip in the microprocessor 20. The A1000 chip receives the image taken by the external camera 30, and performs image recognition and video recording.

[0035] When the voiceprint alarm module 10 does not find any abnormality, the collision sensor 40 , as a supplement to the voiceprint alarm module 10 , can activate the camera 30 to check the situation around the vehicle when the vehicle is hit by a foreign object.

[0036] like Figure 2 As shown, the abnormal awakening system further includes a communication module 60, and the communication module 60 is used for communication connection with an external mobile terminal.

[0037] The external mobile terminal is a mobile device such as a mobile phone, a tablet computer, etc. Taking a mobile phone as an example, when a vehicle is parked on the roadside or in a parking space such as a garage, if the user wants to check the specific situation around the vehicle, the user can communicate with the communication module 60 in the abnormal awakening system through the mobile phone APP to obtain the images taken by each camera 30 and accurately understand the situation of each area around the vehicle.

[0038] Optionally, the communication module 60 is a 4G communication module or a 5G communication module.

[0039] like Figure 2 As shown, the abnormal awakening system also includes a switch 70, which is used to receive signals sent by an external mobile terminal, and the output end of the switch 70 is connected to the microprocessor 20. Optionally, the switch 70 is an Ethernet switch chip RTL9068, which is used to receive messages sent by an external mobile terminal and wake up the TC377 chip in the microprocessor 20. The image captured by the camera 30 is transmitted to the microprocessor 20 through the MAX96722 or other serializer 50 for analysis and processing.

[0040] The utility model also provides a vehicle-mounted navigation device, which comprises the abnormal awakening system as described above.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
