[0028] Example 1

[0029] like Figures 1 to 7 As shown, the millimeter-wave radar alarm trip recorder of this embodiment includes a host 1, and the host 1 is electrically connected to the front device box 2, the rear device box 3, the warning mechanism, the vehicle left turn signal line group 10 and the vehicle right turn signal line group 11 by wires. The input end of the host 1 is electrically connected to the control switch 7, the host 1 is electrically connected to the vehicle power supply through the power connection line group 8, and the host 1 is wirelessly connected to the remote control terminal 9 through the communication module. The rear device box 3 is provided with a rear camera module 31 and a millimeter-wave radar module 32, and the front device box 2 is provided with a front camera module. The host 1 is provided with a main board 14 inside, and the main board 14 is provided with a main control chip and a plurality of functional modules. The millimeter-wave radar module 32 transmits millimeter waves and receives target signals through an antenna. The reflected echo signal is amplified by the high-gain intermediate frequency signal inside the module, and after signal acquisition and signal processing inside the microcontroller, an I / O level signal is output or input to a driving recorder host via a serial port protocol or a CAN protocol. Data analysis is performed based on the distance, speed, direction and other information data of the target detected in real time by the millimeter-wave radar module 32. The driving recorder host formulates corresponding warning states and alarm strategies, such as radar detection of vehicle speed state, BSD blind spot detection state, LCA lane change assist state, radar detection of vehicle close distance warning state, and formulates left lane vehicle alarm strategies, right lane vehicle alarm strategies, rear lane vehicle alarm strategies, etc., and triggers corresponding light and sound warnings as needed.

[0030] Specifically, the main control chip is provided with a storage module, and the functional modules include a positioning module, a communication module, a video control module, a radar signal communication module, a direction sensor module, a voltage regulator and buck module, an SD card module, a host switch module, an LCD screen module and a WiFi module. The WiFi module is used for data connection, the SD card is used for data storage, the radar signal communication module includes a serial communication module and a CAN communication module, and the direction sensor module is used for angle recognition.

[0031] Furthermore, the front end of the lens of the rear camera module 31 and the front end of the antenna mask of the millimeter-wave radar module 32 are on the same plane of the shell of the rear device box 3, and the rear camera module 31 and the millimeter-wave radar module 32 are used for rear driving recording in the same direction.

[0032] Furthermore, the warning mechanism includes a left indicator light 4, a right indicator light 5 and a speaker 6. The host 1 is electrically connected to the left indicator light 4, the right indicator light 5 and the speaker 6 by wires. It is mainly used for the early warning alarm prompt of the millimeter wave radar module. The function that needs to be warned is expressed in the form of light and sound, so that the driver can feel it more intuitively. The left indicator light 4 and the right indicator light 5 are LED lights with multi-color display, which can display red, yellow or other colors that need to be displayed. The light has several warning modes such as lighting, flashing, and flashing. The speaker 6 is a speaker that can play multiple types of sounds. The left indicator light 4 and the right indicator light 5 are not lit in the standby state, and the speaker 6 is not ringing in the standby state; when the millimeter wave radar module 32 of the rear device box 3 starts to work, when the corresponding warning is triggered according to the function, the light signal and sound signal status are as follows:

[0033] 1. When the millimeter-wave radar module 32 is powered on, the left indicator light 4 and the right indicator light 5 flash three times at the same time, and the speaker 6 makes three "beep", "beep", "beep" sounds (the "radar power on" sound can also be played once); when the millimeter-wave radar module 32 is powered off, the left indicator light 4 and the right indicator light 5 flash twice synchronously, and the speaker makes two "beep" and "beep" sounds (the "radar power off" sound can also be played once);

[0034] 2. The warning status of the millimeter wave radar module has the following alarm strategies:

[0035] (1) Radar detection of vehicle speed over-speed warning: The driver of the vehicle can use the remote control terminal 9APP to connect to the dashcam host via Bluetooth to set the vehicle's safe speed value. For example, if the value is set to 80 km / h, the vehicle speed exceeding this value is considered speeding. In the working state, the millimeter-wave radar module 32 detects and analyzes the vehicle speed data in real time. When the dashcam host receives the speed data detected by the millimeter-wave radar module 32 through the serial port protocol or CAN protocol and it is greater than the set value, the main control chip of the dashcam host triggers the left indicator light 4 and the right indicator light 5 to light up synchronously, such as flashing the red light three times and then stopping, and the horn 6 "beep", "beep", "beep" three times and then stops (it can also be an "overspeed alarm" sound once); when the main control chip of the dashcam host detects that the speed data of the millimeter-wave radar module 32 drops to within the safe value, the warning will no longer be triggered and the alarm will be lifted; if the millimeter-wave radar module 32 detects that the vehicle speed still exceeds the preset safety value within 20 seconds after the first warning stops, the warning alarm will be triggered again. This working mode is a cyclic mode when the machine is turned on;

[0036] (2) BSD vehicle blind spot detection warning: "BSD vehicle blind spot" refers to the field of vision that cannot be observed when observing the rear and side vehicles from the left and right rearview mirrors while the vehicle is driving. The vehicle blind spot affects the driving safety of the vehicle. The "blind spot warning area" of the vehicle in this solution is defined as the designated area behind the lane adjacent to the left or right side of the vehicle. For example, starting from the rear of the vehicle, the width of the left or right adjacent lane is 2-5 meters and the length is 10-20 meters (configurable). When other vehicles appear in this area while the vehicle is driving, an alarm will be issued to prompt the driver to be vigilant to prevent accidents. This solution defines the alarm behavior of this area as the first alarm area, also known as the first-level alarm state.

[0037] When the millimeter-wave radar module 32 in the rear device box 3 detects other vehicles in the blind spot area of ​​the left lane of the vehicle, the main control chip of the driving recorder host triggers the left indicator light 4 to light up, such as setting it to a long-lit yellow light state, until there are no other vehicles in the left blind spot, then the warning stops. When the millimeter-wave radar module 32 in the rear device box 3 detects other vehicles in the blind spot area of ​​the right side of the vehicle, the main control chip of the driving recorder host triggers the right indicator light 5 to light up, such as setting it to a long-lit yellow light state, until there are no other vehicles in the left blind spot, then the warning stops. This working mode is a cyclic mode when it is turned on, that is, the indicator light is lit when there is an alarm, and it is in standby mode when there is no alarm;

[0038] (3) LCA vehicle lane change assist warning: The "LCA vehicle lane change assist function" means that when the radar detects that there is a vehicle behind the adjacent lane and the speed exceeds the speed of the vehicle when the vehicle needs to change lanes while driving, it can issue a warning to remind the driver. The range of the vehicle's "lane change warning area" is defined as the designated area behind the adjacent lane on the left or right side of the vehicle, such as the range of 2-5 meters in width and 20-80 meters in length (configurable) of the adjacent lane on the left or right side starting from the rear of the vehicle; when other vehicles appear in this area while the vehicle is driving, an alarm will be issued to prompt the driver to be vigilant to prevent accidents; this solution defines the alarm behavior of this area as the second alarm area, also known as the secondary alarm state.

[0039] When the driver turns on the left turn signal of the vehicle when changing lanes, the signal that the vehicle turn signal has been turned on is input in real time to the millimeter wave radar module 32 in the rear device box 3 through the vehicle left turn signal line group 10. When the millimeter wave radar module 32 detects that there is a vehicle in the "lane change warning area" on the left side of the vehicle, the main control chip of the driving recorder host triggers the left indicator light 4 to light up, which is in a flashing state (for example, set to a low-frequency flashing of a yellow light 1 time / 1s); the speaker 6 plays an alarm sound at a low frequency (for example, set to a "beep" sound, with a playback frequency of 1 time / 1s) until there are no other vehicles in the left "lane change warning area" and stop to warn.

[0040] When the driver of the vehicle turns on the right turn signal of the vehicle when changing lanes, the signal that the vehicle turn signal has been turned on is input to the millimeter wave radar module 32 in the rear device box 3 in real time through the vehicle right turn signal line group 11. When the millimeter wave radar module 32 detects that there is a vehicle in the "lane change warning area" on the right side of the vehicle, the main control chip of the driving recorder host triggers the right indicator light 5 to light up, which is in a flashing state (for example, set to a low-frequency flash of yellow light 1 time / 1s); the speaker 6 plays an alarm sound at a low frequency (for example, set to a "beep" sound, and the playback frequency is 1 time / 1s) until there are no other vehicles in the right "lane change warning area" to stop warning. This working mode is a cycle mode when it is turned on, that is, the indicator light flashes when there is an alarm, and it is in a standby state when there is no alarm.

[0041] (4) Radar detection vehicle is too close to anti-collision warning: The range of the vehicle's "radar detection vehicle is too close to anti-collision warning area" is defined as the designated area of ​​the lane directly behind the vehicle, such as the range of 2-5 meters in width and 1-80 meters in length (settable) from the rear of the vehicle. This area is the third alarm area, also known as the third-level alarm state, or the anti-collision alarm state. When the vehicle is driving normally, the millimeter wave radar module 32 in the rear device box 3 detects that there are other vehicles behind the vehicle with a speed greater than the vehicle, and the rear vehicle is approaching quickly and will collide with the vehicle within 3 seconds, the main control chip of the driving recorder host simultaneously triggers the left indicator light 4 and the right indicator light 5, the light state is fast flashing (for example, set to flash at a high frequency of 3 times / 1s), and the speaker 6 plays an alarm sound at a high frequency (for example, set to play a "beep" sound at a frequency of 2 times / 1s). This working state continues to alarm when the distance between the vehicle and the rear vehicle is close <3s, and the alarm is lifted after >3s. This working mode is a cycle mode when the machine is turned on.

[0042] In a specific embodiment, see Figure 3-5 A wired electrical connection or a wireless communication connection is selected between the host 1 and the control switch 7 to facilitate the control of the host 1 by the control switch 7.

[0043] The method of using this embodiment is as follows: the front device box 2 is installed at the front position of the vehicle (such as on the handlebars, on the headlights, on the front shock absorbers, on the front fenders and other suitable positions). When the front device box 2 is installed, the lens of the front camera module should face the front area of ​​the vehicle, and the lens can properly shoot the vehicle in front. There should be no obstructions in front of the front device box 2. The front camera module in the front device box 2 is used to shoot the video of the object in front of the vehicle. The data shot by the camera is connected to the host of the driving recorder through a wire and the video data analysis, data recording and storage are performed. The shot video data is viewed through the remote control terminal 9APP. The front end of the lens of the rear camera module 31 and the millimeter The front end of the antenna mask of the meter-wave radar module 32 is in a plane, and the rear device box 3 is installed at the rear position of the vehicle (such as the taillight position of the vehicle, the backrest, the rear luggage rack, the rear fender, the rear taillight and other suitable positions). When the rear device box 3 is installed, the lens of the rear camera module 31 and the antenna mask of the millimeter-wave radar module 32 should face the rear area of ​​the vehicle; the lens of the rear camera module 31 can properly shoot the rear vehicle, the antenna of the millimeter-wave radar module 32 can transmit and receive millimeter-wave signals, and there should be no obstructions in front of the rear device box 3. The rear camera module 31 is used to shoot video of the rear of the vehicle, and the data shot by the camera is connected to the driving recorder via a wired connection. The dash cam host performs data analysis, data recording and storage of the video, and the captured video data can be viewed through the remote control terminal 9APP. The millimeter wave radar module 32 transmits millimeter waves through the antenna and receives the echo signal reflected by the target. The echo signal is amplified by the high-gain intermediate frequency signal inside the module, and after signal acquisition and signal processing inside the microcontroller, the I / O level signal is output or input to the dash cam host via the serial port protocol or CAN protocol. Data analysis is performed based on the distance, speed, direction and other information data of the target detected in real time by the millimeter wave radar module 32.
