In view of the shortcomings of the conventional driving recorder, the smart vehicle terminal triggering system and method for solving the defect are provided below. In the following description, the smart vehicle terminal is a terminal device having a photographing function, such as a driving recorder, a smart car mirror, and the like.

FIG. 1 is a schematic diagram of an intelligent vehicle terminal triggering system according to an embodiment.

An intelligent vehicle terminal triggering system includes an input device 100 and an intelligent vehicle terminal 200. The input device 100 and the smart vehicle terminal 200 are communicatively coupled via Bluetooth low energy technology.

The input device 100 is configured to identify an input event, generate broadcast information corresponding to the input event, and transmit the broadcast information through the pre-established Bluetooth trusted communication interface. 2 is a schematic diagram of an input device module of an embodiment. The input device 100 can include an identification module 110, a broadcast generation module 120, and a first communication module 130. The identification module 110 is configured to identify an input event, the broadcast generation module 120 is configured to generate broadcast information corresponding to the input event, and the first communication module 130 is configured to send the broadcast information through the pre-established Bluetooth trusted communication interface. The broadcast information is used to drive the smart vehicle terminal 200 to generate image data in real time. After the image data is generated, the smart vehicle terminal 200 can also store the image data on a local storage medium. The image data includes at least one of a picture and a video generated from video data in which a driving situation is recorded.

Real-time generation of image data can be understood as the start of image data generation in a very short time, which can be understood as a snap shot in a common sense.

The input device 100 is a human-machine interaction device and is mainly used for human-computer interaction. The user can form an input event by performing an input operation on the input device 100, and the input device 100 is based on the user's Response by inputting an action/event. Specifically, the input device 100 may be a button device, a button device, a touch screen device, a joystick, or the like that responds by recognizing a user action.

When the input device 100 is a button device, the user performs an input operation on the input device 100 to form a button event; when the input device 100 is a button device, the user performs an input operation on the input device 100 to form a button event; when the input device 100 When the touch screen device is used, the user inputs the input device 100 to form a touch screen event; when the input device 100 is a rocker device, the user inputs the input device 100 to form a rocker event. Taking the input device 100 as a button device as an example, the button device is used to identify a button event, generate broadcast information corresponding to the button event, and send the broadcast information through the pre-established Bluetooth trust communication interface.

For the input device 100, different input operations may result in different input events, resulting in a different response after the input device 100 recognizes.

For example, the input device 100 is a button device, and the button device may include one button, and may also include more than one button. In order to improve convenience, the button device in this embodiment may include only one button. The button events of the same button can include two types, one for short press events and the other for long press events. The short press event is defined as a button event in which the pressing time of the button is less than the first preset duration (for example, 3 seconds), and the long pressing event is defined as a button event in which the pressing duration of the button is greater than the third preset duration (for example, 5 seconds). Generally speaking, by de-shake the software program on the button, the user can quickly recognize the short-press event by pressing the button, and the user can recognize the long-press event by pressing the button (confirmed after the button is released). .

Taking the input device 100 as an example of a touch screen device, the touch screen device may include a touch screen to identify a touch screen event by recognizing a point or track at which the user operates at the touch screen. For example, a user's finger touching a point on the touch screen can be recognized as a touch event, and a user's finger sliding on the touch screen to form a sliding track can be recognized as a sliding event. Of course, the touch event can also be like the above-mentioned button event, including a short touch event and a long touch event, that is, the touch screen device can have a virtual button, and the virtual button can also be understood as the button of the button device. This will not be repeated here.

After the identification module 110 identifies the input event, the broadcast generation module 120 generates broadcast information corresponding to the input event. Different input events usually produce different broadcast information. Taking the input device 100 as a button device as an example, the button event may include two types, one is a short press event, The other is a long press event. The following example describes how the broadcast generation module 120 responds to the identification module 110 to generate corresponding broadcast information.

After the identification module 110 identifies the short press event, the broadcast generating module 120 generates broadcast information corresponding to the short press event, and the broadcast information may be used to drive the smart vehicle terminal 200 to generate a picture in real time, and store the picture in a local storage medium. Real-time generation of images can be understood as the start of generating images in a very short time, which can be understood as a snap shot in a popular way.

After the recognition module 110 recognizes the long press event, the broadcast generation module 120 generates broadcast information corresponding to the long press event, and the broadcast information may be used to drive the smart vehicle terminal 200 to generate a video in real time, and store the video in a local storage medium. Real-time video generation can be understood as the start of video generation in a very short time, which can be understood as a snap video in a popular way.

Of course, when the input device 100 is a touch screen device, it is also possible to generate the broadcast information by identifying the short touch event and the long trigger event respectively to drive the smart vehicle terminal 200 to generate pictures and videos; when the input device 100 is a button device and a joystick device, etc. The input device is similar, and will not be described in depth here.

The input device 100 also includes a display module that enters a corresponding display mode in accordance with an input event. For example, if the recognition module 110 recognizes a short press event, the display module enters the first display mode; if the recognition module 110 recognizes the long press event, the display module enters the second display mode. The first display mode and the second display mode should be different. The display module is an LED light. The first display mode can be the light flashing once, and the second display mode can be the light flashing multiple times; or, the first display mode The light can be flashed once, and the second display mode can be always on.

After the broadcast generation module 120 generates the broadcast information, the first communication module 130 is configured to send the broadcast information through the pre-established Bluetooth trust communication interface.

The first communication module 130 of the input device 100 and the second communication module 210 of the smart vehicle terminal 200 (please refer to FIG. 3) may form a Bluetooth connection. The first communication module 130 and the second communication module 210 can both be Bluetooth modules. The pre-established Bluetooth trusted communication interface can be understood as the first communication module 130 has been previously paired with the second communication module 210. Communication Interface. For example, the input device 100 and the smart car terminal 200 have been pre-Bluetooth paired before shipment, or the input device 100 and the smart car terminal 200 have reached the user's hand and then paired their Bluetooth. Input device 100 and intelligent vehicle terminal after one Bluetooth pairing 200, it is equivalent to pre-establishing the Bluetooth trust communication interface, so that the input device 100 and the smart vehicle terminal 200 can directly establish a trust connection when the next Bluetooth connection is made, and no Bluetooth pairing is performed.

Therefore, in the broadcast information, the uniquely recognized feature information of the input device 100, such as at least one of a physical address (MAC) and an identifier (ID), is usually included, so that the smart car terminal 200 can be pre-Bluetooth paired. It joins the trust list and can be identified and automatically established directly on the next connection.

In order to minimize power consumption, Bluetooth Low Energy Technology (BLE) is employed between the first communication module 130 and the second communication module 210. BLE technology uses a variable connection time interval, which can be set from a few milliseconds to a few seconds depending on the application. In addition, because the BLE technology uses a very fast connection method, it can usually be in a "non-connected" state (standby state) to reduce power consumption. At this time, the two ends of the link only know each other, and only open the chain when necessary. Road, then close the link in the shortest possible time.

Therefore, the input device 100 can be in a standby state when it is not necessary to transmit the broadcast information, and after recognizing the input event, the input device 100 switches from the standby state to the broadcast state to transmit the broadcast information. The input device 100 periodically transmits broadcast information during a preset broadcast duration during transmission of broadcast information. For example, in a period of 100 milliseconds, after the short press event is recognized, the broadcast information is transmitted 5 times in 500 milliseconds; for example, in a period of 100 milliseconds, after the long press event is recognized, the broadcast is sent within 15 seconds. 150 broadcast messages.

After the broadcast device transmits the broadcast information, the input device 100 can switch from the broadcast state to the standby state to save energy.

The broadcast information may also include at least one of an input event code and a remaining battery power. The input event code is used to distinguish different input events. Taking a button event as an example, a short press event may be indicated by 1 and a long press event may be indicated by 2; and each input event represents a different command function, such as a short press event representative The command function of generating a picture, the long press event represents an instruction function for generating a video, and the smart vehicle terminal 200 responds to the function instruction corresponding to the input event code and performs a corresponding action. The remaining battery power is the remaining battery power information of the input device 100. When the smart vehicle terminal 200 obtains the remaining battery power information from the broadcast information, the alarm information is sent when the remaining battery power is lower than the preset power value. For example, when the remaining battery power is lower than the total battery power At 10% of the time, the smart vehicle terminal 200 can issue a prompt to the vehicle owner in the form of an audible warning or the like, prompting the vehicle owner to charge or replace the battery for the input device 100.

In BLE technology, broadcast information usually has the following data structure:

PreamblePreamble	Access AddressAccess Address	PDUPDU	CRCCRC
1(字节)1 (bytes)	4(字节)4 (bytes)	2-39(字节)2-39 (bytes)	3(字节)3 (bytes)
0x250x25	0x8E89BED60x8E89BED6

Preamble is the preamble, Access Address is the access address, PDU is the payload data, and CRC is the check code.

The PDU data has the following data structure:

The Header is the data header and the Payload is the payload data. Payload is divided into two parts, AdvA is the broadcast address, and AdvData is the broadcast data. Header usually includes broadcast type information, for example:

ADV_IND: Connectable to non-directional broadcast

ADV_DIRECT_IND: Connectable directed broadcast

ADV_NONCONN_IND: Unconnectable non-directional broadcast

ADV_SCAN_IND: Scannable non-directional broadcast

The physical address of the input device 100 can be placed in AdvA, and the identifier, input event code, and battery level can be placed in AdvData. The identifier may include a Universally Unique Identifier (UUID).

Of course, the broadcast information may only include the physical address of the input device and the input event code, without including the tag and the battery level. Alternatively, the broadcast information may include only the physical address of the input device, the input event code, and the battery level, without including a tag. After receiving the broadcast information, the smart vehicle terminal 200 verifies whether the physical address of the input device 100 matches the physical address stored by itself, and if so, generates image data in response to the input event code, for example, in response to a short press event code, in response to Long press the event code to generate a video.

If the wireless "on" time is not very short, the battery life will be drastically reduced. The required sending or receiving tasks need to be completed quickly. In Bluetooth low energy technology, the first technique for wireless turn-on time is to search for other devices with only three "broadcast" channels, or to announce their existence to devices seeking to establish a connection. In contrast, standard Bluetooth technology uses 32 channels. This means that Bluetooth low energy technology scans other devices only by "on" for 0.6 to 1.2ms, while standard Bluetooth technology takes 22.5ms to scan its 32 channels. Therefore, Bluetooth low energy technology requires 10 to 20 times lower power consumption for other wireless devices than standard Bluetooth technology.

Therefore, the input device 100 communicates with the smart in-vehicle terminal 200 using the broadcast information in the BLE technology, so that the communication between the input device 100 and the smart in-vehicle terminal 200 can achieve low power consumption, and enables the smart in-vehicle terminal 200 to quickly acquire commands and Respond to greatly improve the user experience and ease of use.

The smart vehicle terminal 200 is configured to receive broadcast information transmitted by the input device 100 through the above-described Bluetooth trust communication interface; generate image data in real time in response to the broadcast information, and store the image data in a local storage medium.

FIG. 3 is a schematic diagram of an intelligent vehicle terminal module of an embodiment. The smart vehicle terminal 200 may include a second communication module 210, an image generation module 220, and a storage module 230. The second communication module 210 is configured to receive the broadcast information sent by the input device 100 through the Bluetooth trusted communication interface; the image generating module 220 is configured to generate image data in real time in response to the broadcast information; and the storage module 230 stores the image data in the local storage medium. . The local storage medium may be, for example, a storage medium such as a hard disk or a flash memory. The storage medium may be disposed in the smart vehicle terminal 200 in a fixed form, or may be in a movable form, for example, the storage medium may be a removable hard disk or a pluggable flash memory or the like.

The image data may include at least one of a picture and a video generated from video data in which a driving situation is recorded. In general, in one generation, the generated image data includes only pictures or only video. Of course, the case where the image data includes both pictures and videos is not excluded.

In the embodiment, when the input device 100 recognizes the short press event or the short touch event, the smart vehicle terminal 200 responds to generate a picture according to the corresponding broadcast information of the input event; when the input device 100 recognizes the long press event When the event is long touched, the smart vehicle terminal 200 responds to generate a video based on the broadcast information corresponding to the input events. The following description will be made by taking the input device 100 as a button device as an example.

The picture includes a picture with the best definition in the video data in the second preset time period before or after the smart car terminal 200 receives the broadcast information. The broadcast information is the broadcast information corresponding to the short press event.

In other words, the picture is captured from the video data. It is assumed that the smart car terminal 300 receives the broadcast information at the time A, the second preset time is a duration, and captures the sharpness from the video data recorded by the smart vehicle terminal 300 within a time period before or after the A time. The best picture. Generally, the picture with the best definition is captured from the video data recorded by the smart vehicle terminal 300 within a time period before the time A. This is because when the owner operates the button device, the video picture that the owner wants to share may have been missed, so the picture can be obtained from the past video picture as appropriate. For example, the video picture that the owner wants to share when the button is pressed is usually missed. The missed time can be set within 1 second, that is, the duration of a is 1 second. In this way, when the owner presses the button, the captured image is the best picture in the video within 1 second before the button is pressed (the moment when the short press event is recognized).

The video includes a video determined according to the moment when the smart vehicle terminal 200 receives the broadcast information. The broadcast information is broadcast information corresponding to a long press event.

In other words, the video is also captured from the video data. It is assumed that the smart car terminal 300 receives the broadcast information at the time A, and the fourth preset time is b. At the time of Ab (for example, A is 13:00, b is 1 second, and Ab is 12:59:59). Then, the A+b time is 13:00:01; the same time) starts counting until the end of the long press event, and the video is the video data captured from the time zone. Again, this is because when the owner operates the button device, the video picture that the owner wants to share may have been missed, so the video can be properly acquired from the past video frame. For example, the video picture that the owner wants to share when the button is pressed is usually missed. The missed time can be set within 1 second, that is, the b time is also 1 second. Thus, when the owner presses a button, the captured video is the video data that starts counting 1 second before the button is pressed (the time at which the long press event is recognized).

The above embodiment is also applicable when the input device 100 is a touch screen device, and it is only necessary to replace the short press event described above with a short touch event and a long press event for a new touch event.

FIG. 4 is a schematic flowchart of a method for triggering an intelligent vehicle terminal according to an embodiment. Please refer to Figures 1-3.

The invention also provides a smart vehicle terminal triggering method, the method comprising the following steps:

Step S110: The input device 100 recognizes the input event, generates broadcast information corresponding to the input event, and transmits the broadcast information through the pre-established Bluetooth trusted communication interface.

The input device 100 can include an identification module 110, a broadcast generation module 120, and a first communication module 130. Please refer to Figure 2.

The input device 100 is a human-machine interaction device and is mainly used for human-computer interaction. The user can form an input event by performing an input operation on the input device 100, and the input device 100 responds according to the user's input operation/event. Specifically, the input device 100 may be a button device, a button device, a touch screen device, a joystick, or the like that responds by recognizing a user action.

After the identification module 110 identifies the input event, the broadcast generation module 120 generates broadcast information corresponding to the input event. Different input events usually produce different broadcast information. Taking the input device 100 as a button device as an example, the button event may include two types, one is a short press event, and the other is a long press event. The following example describes how the broadcast generation module 120 responds to the identification module 110 to generate corresponding broadcast information.

Of course, when the input device 100 is a touch screen device, it is also possible to identify a short touch event. Generating broadcast information with the long trigger event respectively drives the smart vehicle terminal 200 to generate pictures and videos; similarly when the input device 100 is a button device and other input devices such as a joystick device, it will not be described in depth here.

The first communication module 130 of the input device 100 and the second communication module 210 of the smart vehicle terminal 200 (please refer to FIG. 3) may form a Bluetooth connection. The first communication module 130 and the second communication module 210 can both be Bluetooth modules. The pre-established Bluetooth trusted communication interface can be understood as the first communication module 130 has been previously paired with the second communication module 210. Communication Interface. For example, the input device 100 and the smart car terminal 200 have been pre-Bluetooth paired before shipment, or the input device 100 and the smart car terminal 200 have reached the user's hand and then paired their Bluetooth. After the Bluetooth pairing input device 100 and the smart vehicle terminal 200, it is equivalent to pre-establishing the Bluetooth trust communication interface, so that the input device 100 and the smart vehicle terminal 200 can directly establish a trusted connection when the Bluetooth connection is next performed, and no longer perform Bluetooth. pair.

In order to minimize power consumption, Bluetooth Low Energy Technology (BLE) is employed between the first communication module 130 and the second communication module 210. BLE technology uses a variable connection time interval, which can be set from a few milliseconds to a few seconds depending on the application. In addition, because BLE technology uses a very fast connection, it can usually be in a "non-connected" state (Standby, Standby state) to reduce energy consumption, at this time the two ends of the link only know each other, only open the link when necessary, and then close the link in the shortest possible time.

The broadcast information may also include at least one of an input event code and a remaining battery power. The input event code is used to distinguish different input events. Taking a button event as an example, a short press event may be indicated by 1 and a long press event may be indicated by 2; and each input event represents a different command function, such as a short press event representative The command function of generating a picture, the long press event represents an instruction function for generating a video, and the smart vehicle terminal 200 responds to the function instruction corresponding to the input event code and performs a corresponding action. The remaining battery power is the remaining battery power information of the input device 100. When the smart vehicle terminal 200 obtains the remaining battery power information from the broadcast information, the alarm information is sent when the remaining battery power is lower than the preset power value. For example, when the remaining battery power is less than 10% of the total power, the smart vehicle terminal 200 can issue a prompt to the vehicle owner in the form of an audible warning or the like, prompting the vehicle owner to charge or replace the battery for the input device 100.

The PDU data has the following data structure:

ADV_IND: Connectable to non-directional broadcast

ADV_DIRECT_IND: Connectable directed broadcast

ADV_NONCONN_IND: Unconnectable non-directional broadcast

ADV_SCAN_IND: Scannable non-directional broadcast

Wireless "on" time, as long as it is not very short, can drastically reduce battery life, so any necessary send or receive tasks need to be completed quickly. In Bluetooth low energy technology, the first technique for wireless turn-on time is to search for other devices with only three "broadcast" channels, or to announce their existence to devices seeking to establish a connection. In contrast, standard Bluetooth technology uses 32 channels. This means that Bluetooth low energy technology scans other devices only by "on" for 0.6 to 1.2ms, while standard Bluetooth technology takes 22.5ms to scan its 32 channels. Therefore, Bluetooth low energy technology requires 10 to 20 times lower power consumption for other wireless devices than standard Bluetooth technology.

After step S110, step S120 is performed.

Step S120: The smart vehicle terminal 200 receives the broadcast information transmitted by the input device 100 through the above-mentioned Bluetooth trust communication interface; generates image data in real time in response to the broadcast information, and stores the image data in the local storage medium.

In other words, the picture is captured from the video data. It is assumed that the smart car terminal 300 receives the broadcast information at the time A, the second preset time is a duration, and captures the sharpness from the video data recorded by the smart vehicle terminal 300 within a time period before or after the A time. The best picture. Generally, the picture with the best definition is captured from the video data recorded by the smart vehicle terminal 300 within a time period before the time A. This is because when the owner operates the button device, the video picture that the owner wants to share may have been missed, so the picture can be obtained from the past video picture as appropriate. For example, usually the owner wants to share when the button is pressed. The video screen has been missed, and this missed time can be set within 1 second, that is, the duration of a is 1 second.
