When input equipment 100 is press key equipment, user carries out input operation to input equipment 100 will form key-press event; When input equipment 100 is button devices, user carries out input operation to input equipment 100 will form button event; When input equipment 100 is touch panel device, user carries out input operation to input equipment 100 will form touchscreen events; When input equipment 100 is rocking bar equipment, user carries out input operation to input equipment 100 will form rocking bar event.Are press key equipments for input equipment 100, press key equipment is used for key range event, produces the broadcast message corresponding with key-press event, by pre-established bluetooth trust communication interface transmission broadcast message.
For input equipment 100, different input operations, may form different incoming event, thus makes different response after causing input equipment 100 to identify.
Are press key equipments for input equipment 100, this press key equipment can comprise a button, also can comprise more than one button.In order to promote convenience, in the present embodiment, press key equipment can only include a button.The key-press event of same button can comprise two kinds, and one is short in event, another kind of for length is by event.Short by event definition be button press the key-press event that duration is less than the first preset duration (such as 3 seconds), long by event definition be button press the key-press event that duration is greater than the 3rd preset duration (such as 5 seconds).Typically, by carrying out the debounce processing on software program to button, user is pushed button unclamp to be identified as short in event at once, user continue to push button can be identified as long by event (unclamping rear confirmation from button).
When being touch panel devices for input equipment 100 again, this touch panel device can comprise touch-screen, by identifying that user identifies touchscreen events at the point of touch screen operation or track.Such as, the finger of user touches can be identified as by the point on touch-screen and touches by event, and the finger of user slides to form sliding trace on the touchscreen can be identified as slip event.Certainly, touching also can as above-mentioned key-press event by event, comprises shortly touching by event and longly touching by event, is also that touch panel device can exist virtual button, this virtual key and also can be understood as the button of above-mentioned press key equipment, does not repeat them here.
After identification module 110 identifies incoming event, broadcast generation module 120 produces the broadcast message corresponding with incoming event.Different incoming event, produces different broadcast message usually.Are press key equipments for input equipment 100, key-press event can comprise two kinds, and one is short in event, another kind of for long by event.Below how citing description broadcast generation module 120 responds identification module 110 and generates corresponding broadcast message.
When identification module 110 identify short by event after, broadcast generation module 120 produces with short by the corresponding broadcast message of event, and this broadcast message may be used for ordering about the real-time generating pictures of intelligent vehicle mounted terminal 200, by described picture-storage in local storage medium.Real-time generating pictures can be understood as and start generating pictures in very short time, can be understood as candid photograph picture with popular saying.
When identification module 110 identifies long by after event, broadcast generation module 120 produces and the long broadcast message corresponding by event, and this broadcast message may be used for ordering about intelligent vehicle mounted terminal 200 generating video in real time, by described video storage in local storage medium.Real-time generating video can be understood as and start generating video in very short time, can be understood as candid photograph video with popular saying.
Certainly, when input equipment 100 is touch panel devices, also can by identifying that short touching generates broadcast message respectively by event and long trigger event and order about intelligent vehicle mounted terminal 200 generating pictures and video; Also similar when input equipment 100 is other input equipments such as button devices and rocking bar equipment, no longer deeply describe at this.
Input equipment 100 also comprises display module, and display module enters corresponding display mode according to incoming event.Such as, if identification module 110 identifies short in event, then display module enters the first display mode; If identification module 110 identifies long by event, then display module enters the second display mode.First display mode and the second display mode should be distinguished to some extent, take display module as LED are example, and the first display mode can dodge once for lamp, the second display mode can for lamp sudden strain of a muscle repeatedly; Or the first display mode can dodge once for lamp, and the second display mode can be often bright.
After broadcast generation module 120 generates broadcast message, first communication module 130 sends broadcast message for trusting communication interface by pre-established bluetooth.
The first communication module 130 of input equipment 100 can form bluetooth with the second communication module 210 (incorporated by reference to Fig. 3) of intelligent vehicle mounted terminal 200 and be connected.First communication module 130 and second communication module 210 can be all bluetooth module, described pre-established bluetooth trusts communication interface, can be understood as first communication module 130 and carries out Bluetooth pairing with second communication module 210 in advance and the communication interface that formed.Such as, input equipment 100 and intelligent vehicle mounted terminal 200 just carried out Bluetooth pairing in advance before dispatching from the factory, or input equipment 100 and intelligent vehicle mounted terminal 200 to have arrived in user's hand user again by its Bluetooth pairing.Through input equipment 100 and the intelligent vehicle mounted terminal 200 of a Bluetooth pairing, just be equivalent to bluetooth pre-established and trusted communication interface, such input equipment 100 once carries out can directly breaking the wall of mistrust when bluetooth is connected connection with intelligent vehicle mounted terminal 200 upper, no longer carries out Bluetooth pairing.
Therefore in broadcast message; usually the characteristic information of unique identification of input equipment 100 can also be comprised; such as, in physical address (MAC) and identifier (ID) at least one; such intelligent vehicle mounted terminal 200 just can be added trust list when Bluetooth pairing in advance, can identify and directly automatically connect when next time connects.
In order to reduce power consumption to greatest extent, between first communication module 130 and second communication module 210, adopt bluetooth low energy consumption technologies (BLE).BLE technology adopts variable connect hours interval, and this interval can not be set to several milliseconds to several seconds not etc. according to embody rule.In addition, because BLE technology adopts connected mode very fast, therefore " disconnected " state (Standby can be at ordinary times, holding state) to reduce energy consumption, now both link ends just knows the other side each other, only have and just open link where necessary, then within the time short as far as possible, close link.
Therefore, input equipment 100 can be in holding state when not needing to send broadcast message, and after identifying incoming event, input equipment 100 is switched to broadcast state to send broadcast message from holding state.Input equipment 100, during transmission broadcast message, normally sends broadcast message in the broadcast duration periodically preset.Such as, be a cycle with 100 milliseconds, identify short by event after, in 500 milliseconds send 5 broadcast messages; Again such as, be a cycle with 100 milliseconds, identify long by event after, in 15 seconds, send 150 broadcast messages.
Input equipment 100, after sending broadcast message, can be switched to holding state from broadcast state, with energy efficient.
Broadcast message can also comprise at least one in incoming event code and battery dump energy.Incoming event code, for distinguishing different incoming events, for key-press event, can represent short in event with 1, represents long by event with 2; And each incoming event represents different command functions, the such as short command function representing generating pictures by event, the long command function representing generating video by event, intelligent vehicle mounted terminal 200 is in response to the function command corresponding to this incoming event code and carry out corresponding action.Battery dump energy is the battery dump energy information of input equipment 100, when intelligent vehicle mounted terminal 200 gets this battery dump energy information from broadcast message, and sends warning information at described battery dump energy lower than during default charge value.Such as, when battery dump energy lower than total electricity 10% time, intelligent vehicle mounted terminal 200 can send prompting by forms such as audible alert to car owner, prompting car owner charge for input equipment 100 or change battery.
In BLE technology, usual broadcast message has following data structure:
| Preamble | Access Address | PDU | CRC |
| 1 (byte) | 4 (bytes) | 2-39 (byte) | 3 (bytes) |
| 0x25 | 0x8E89BED6 |
Preamble is preamble, and AccessAddress is reference address, and PDU is payload data, and CRC is check code.
PDU data have following data structure:
Wherein Header is data head, and Payload is load data.Payload is divided into two parts, and AdvA is broadcast address, and AdvData is broadcast data.Header generally includes broadcast-type information, such as:
ADV_IND: omnidirectional broadcast can be connected
ADV_DIRECT_IND: can directional broadcasting be connected
ADV_NONCONN_IND: omnidirectional broadcast can not be connected
ADV_SCAN_IND: omnidirectional broadcast can be scanned
The physical address of input equipment 100 can be positioned over AdvA, and identifier, incoming event code and battery electric quantity can be positioned over AdvData.Identifier can comprise general unique identifier (UUID, UniversallyUniqueIdentifier).
Certainly, broadcast message can only include physical address and the incoming event code of input equipment, and does not need to comprise marker character and battery electric quantity.Or broadcast message can only include the physical address of input equipment, incoming event code and battery electric quantity, and does not need to comprise marker character.After intelligent vehicle mounted terminal 200 receives broadcast message, whether the physical address of checking input equipment 100 mates with the physical address self stored, if coupling, response incoming event code building view data, such as in response to short event code and the generating pictures pressed, in response to long event code and the generating video pressed.
The time of wireless " unlatching " sharply reduces so long as not the very short battery life that will make, and therefore any required transmission or reception task need to complete very soon.In bluetooth low energy consumption technologies, wireless open-interval first skill only uses 3 " broadcast " channel search miscellaneous equipments, or self exist to the equipment declaration seeking to connect.By contrast, standard bluetooth technology employs 32 channels.This means that bluetooth low energy consumption technologies scanning miscellaneous equipment only needs " unlatching " 0.6 to 1.2ms time, and standard bluetooth technology needs the 22.5ms time to scan its 32 channels.So the power consumption that bluetooth low energy consumption technologies is located needed for other wireless device is lower than standard bluetooth technology 10 to 20 times.
Therefore, input equipment 100 adopts the broadcast message in BLE technology to communicate with intelligent vehicle mounted terminal 200, the communication between input equipment 100 and intelligent vehicle mounted terminal 200 is made to realize low energy consumption, intelligent vehicle mounted terminal 200 quick obtaining instruction can be made again and make response, greatly improving Consumer's Experience and ease of use.
The broadcast message that intelligent vehicle mounted terminal 200 is sent for being trusted communication interface reception input equipment 100 by above-mentioned bluetooth; In response to the real-time image data generating of broadcast message, and view data is stored in local storage medium.
Fig. 3 is the intelligent vehicle mounted terminal module diagram of an embodiment.Intelligent vehicle mounted terminal 200 can comprise second communication module 210, Computer image genration module 220 and memory module 230.Second communication module 210 is for trusting by above-mentioned bluetooth the broadcast message that communication interface receives input equipment 100 transmission; Computer image genration module 220 is in response to the real-time image data generating of described broadcast message; View data is stored in local storage medium by memory module 230.Local storage medium can be such as the storage medium of hard disk or flash memory and so on.Storage medium can be arranged in intelligent vehicle mounted terminal 200 with fixing form, and also can be moveable form, such as storage medium can be mobile hard disk or pluggable flash memory etc.
Described view data can comprise at least one from recording in the picture and video that generate the video data of driving situation.Typically, in once generating, the view data of generation only includes picture or only includes video.Certainly, rejection image data had not both comprised the situation that picture also comprises video.
In the present embodiment, when input equipment 100 identify above-mentioned short by event or short touch by event time, intelligent vehicle mounted terminal 200 responds generating pictures according to the corresponding broadcast message of these incoming events; When input equipment 100 identify above-mentioned length by event or long touch by event time, intelligent vehicle mounted terminal 200 responds generating video according to the corresponding broadcast message of these incoming events.Following description is done for during press key equipment for input equipment 100.

Certainly, when input equipment 100 is touch panel devices, also can by identifying that short touching generates broadcast message respectively by event and long trigger event and order about intelligent vehicle mounted terminal 200 generating pictures and video; Also similar when input equipment 100 is other input equipments such as button devices and rocking bar equipment, no longer deeply describe at this.
Input equipment 100 also comprises display module, and display module enters corresponding display mode according to incoming event.Such as, if identification module 110 identifies short in event, then display module enters the first display mode; If identification module 110 identifies long by event, then display module enters the second display mode.First display mode and the second display mode should be distinguished to some extent, take display module as LED are example, and the first display mode can dodge once for lamp, the second display mode can for lamp sudden strain of a muscle repeatedly; Or the first display mode can dodge once for lamp, and the second display mode can be often bright.
After broadcast generation module 120 generates broadcast message, first communication module 130 sends broadcast message for trusting communication interface by pre-established bluetooth.
The first communication module 130 of input equipment 100 can form bluetooth with the second communication module 210 (incorporated by reference to Fig. 3) of intelligent vehicle mounted terminal 200 and be connected.First communication module 130 and second communication module 210 can be all bluetooth module, described pre-established bluetooth trusts communication interface, can be understood as first communication module 130 and carries out Bluetooth pairing with second communication module 210 in advance and the communication interface that formed.Such as, input equipment 100 and intelligent vehicle mounted terminal 200 just carried out Bluetooth pairing in advance before dispatching from the factory, or input equipment 100 and intelligent vehicle mounted terminal 200 to have arrived in user's hand user again by its Bluetooth pairing.Through input equipment 100 and the intelligent vehicle mounted terminal 200 of a Bluetooth pairing, just be equivalent to bluetooth pre-established and trusted communication interface, such input equipment 100 once carries out can directly breaking the wall of mistrust when bluetooth is connected connection with intelligent vehicle mounted terminal 200 upper, no longer carries out Bluetooth pairing.
Therefore in broadcast message; usually the characteristic information of unique identification of input equipment 100 can also be comprised; such as, in physical address (MAC) and identifier (ID) at least one; such intelligent vehicle mounted terminal 200 just can be added trust list when Bluetooth pairing in advance, can identify and directly automatically connect when next time connects.
In order to reduce power consumption to greatest extent, between first communication module 130 and second communication module 210, adopt bluetooth low energy consumption technologies (BLE).BLE technology adopts variable connect hours interval, and this interval can not be set to several milliseconds to several seconds not etc. according to embody rule.In addition, because BLE technology adopts connected mode very fast, therefore " disconnected " state (Standby can be at ordinary times, holding state) to reduce energy consumption, now both link ends just knows the other side each other, only have and just open link where necessary, then within the time short as far as possible, close link.
Therefore, input equipment 100 can be in holding state when not needing to send broadcast message, and after identifying incoming event, input equipment 100 is switched to broadcast state to send broadcast message from holding state.Input equipment 100, during transmission broadcast message, normally sends broadcast message in the broadcast duration periodically preset.Such as, be a cycle with 100 milliseconds, identify short by event after, in 500 milliseconds send 5 broadcast messages; Again such as, be a cycle with 100 milliseconds, identify long by event after, in 15 seconds, send 150 broadcast messages.
Input equipment 100, after sending broadcast message, can be switched to holding state from broadcast state, with energy efficient.
Broadcast message can also comprise at least one in incoming event code and battery dump energy.Incoming event code, for distinguishing different incoming events, for key-press event, can represent short in event with 1, represents long by event with 2; And each incoming event represents different command functions, the such as short command function representing generating pictures by event, the long command function representing generating video by event, intelligent vehicle mounted terminal 200 is in response to the function command corresponding to this incoming event code and carry out corresponding action.Battery dump energy is the battery dump energy information of input equipment 100, when intelligent vehicle mounted terminal 200 gets this battery dump energy information from broadcast message, and sends warning information at described battery dump energy lower than during default charge value.Such as, when battery dump energy lower than total electricity 10% time, intelligent vehicle mounted terminal 200 can send prompting by forms such as audible alert to car owner, prompting car owner charge for input equipment 100 or change battery.
In BLE technology, usual broadcast message has following data structure:
| Preamble | Access Address | PDU | CRC |
| 1 (byte) | 4 (bytes) | 2-39 (byte) | 3 (bytes) |
| 0x25 | 0x8E89BED6 |
Preamble is preamble, and AccessAddress is reference address, and PDU is payload data, and CRC is check code.
PDU data have following data structure:
Wherein Header is data head, and Payload is load data.Payload is divided into two parts, and AdvA is broadcast address, and AdvData is broadcast data.Header generally includes broadcast-type information, such as:
ADV_IND: omnidirectional broadcast can be connected
ADV_DIRECT_IND: can directional broadcasting be connected
ADV_NONCONN_IND: omnidirectional broadcast can not be connected
ADV_SCAN_IND: omnidirectional broadcast can be scanned
The physical address of input equipment 100 can be positioned over AdvA, and identifier, incoming event code and battery electric quantity can be positioned over AdvData.Identifier can comprise general unique identifier (UUID, UniversallyUniqueIdentifier).
Certainly, broadcast message can only include physical address and the incoming event code of input equipment, and does not need to comprise marker character and battery electric quantity.Or broadcast message can only include the physical address of input equipment, incoming event code and battery electric quantity, and does not need to comprise marker character.After intelligent vehicle mounted terminal 200 receives broadcast message, whether the physical address of checking input equipment 100 mates with the physical address self stored, if coupling, response incoming event code building view data, such as in response to short event code and the generating pictures pressed, in response to long event code and the generating video pressed.
The time of wireless " unlatching " sharply reduces so long as not the very short battery life that will make, and therefore any required transmission or reception task need to complete very soon.In bluetooth low energy consumption technologies, wireless open-interval first skill only uses 3 " broadcast " channel search miscellaneous equipments, or self exist to the equipment declaration seeking to connect.By contrast, standard bluetooth technology employs 32 channels.This means that bluetooth low energy consumption technologies scanning miscellaneous equipment only needs " unlatching " 0.6 to 1.2ms time, and standard bluetooth technology needs the 22.5ms time to scan its 32 channels.So the power consumption that bluetooth low energy consumption technologies is located needed for other wireless device is lower than standard bluetooth technology 10 to 20 times.
