Referring to Fig. 2, Fig. 2 is the side of the attribute information of another acquisition interbehavior instruction provided by the embodiments of the present application
The schematic flow diagram of method.Wherein, which is the angle from the control device and terminal that are installed on vehicle
Description.As shown in Fig. 2, this method can include:
S201, control equipment starting, start above-mentioned serviced component, establish the sub thread of serviced component.
Specifically, when vehicle is lighted a fire and started, middle control starting starts serviced component (service), serviced component energy
The characteristics of enough utilizing thread pool, to create sub thread using thread pool to complete process.
Thread pool is a kind of multithread processing method, and task is added to queue in treatment process, then in creation thread
Start these tasks automatically afterwards.Thread pool threads are all background threads, and per thread is all using the storehouse size of default, with default
Priority operation, and in the multiple thread units.If some thread is in idle condition, then thread pool will dispatch one
Task gives it, if all threads of all remain busy, but task is put into a queue, then thread pool will be one
Another worker thread is created after the section time, but the number of thread is never more than maximum value.Thread more than maximum value can
To be lined up, but they will be until just starting after the completion of other threads.
Therefore, in automotive ignition, when control device starts, start serviced component, after said modules can be created independently
Platform process only considers the process that connection is established with terminal, then serviced component under the premise of being not responding to the process of central control system
Sub thread is created using the principle of thread pool, to facilitate subsequent processing.
S202, terminal starting, initialization emit communication signal.
Specifically, terminal also starts, and carries out the necessary initialization of terminal, so that terminal carries out acquisition and sends data flow
Prepare.The communication signal includes but is not limited to the wireless signals such as WiFi, 3G, 4G, is also possible to the communication signal of wired connection.
Wherein, terminal after start-up, needs the regular hour to be initialized.
S203, control equipment send heartbeat packet to terminal.
The sub thread that control equipment is established after the completion of starting serviced component sends heartbeat packet to detect terminal first
State.
Specifically, above-mentioned heartbeat packet, which refers to, notifies one of other side oneself state oneself definition in client and terminal room timing
Command word, sent according to certain time interval, be similar to heartbeat, so being called heartbeat packet.For judge other side (equipment,
Process or other network elements) whether normal operation, using simple communication packet is regularly sent, if do not received in section at the appointed time
Other side's response, then judge that other side has been off.It is disconnected for detecting the abnormal of connection.In the embodiment of the present application, client (control
Control equipment) heartbeat packet periodically is sent to terminal (intelligent network connection vehicle device), because client needs to judge that terminal is that transmitting is wireless
The state or dormant state of local area network, above-mentioned heartbeat packet are exactly that client regularly sends simple information to terminal, at this
In, the content of heartbeat packet be r n simple communication packet, do not expend flow substantially.Developer the main thought for writing code just
It is that (such as 1 minute, 2 minutes, 5 minutes, here without limitation) send a fix information to terminal every few minutes, terminal is received
A fix information is replied after arriving, if (such as 30 seconds, 1 minute, two minutes, here without limitation) is replied in terminal a few minutes
The information of client then regards disconnecting.
I.e. heartbeat detection can be client every time interval occur a detection packet (send here r n letter
Single-pass news packet) terminal is given, start an overtime timer when client is given out a contract for a project；Terminal has received detection packet, it should
It responds client one packet and illustrates that terminal is normal if client receives the response bag of terminal transmission, delete time-out timing
Device；If the overtime timer time-out of client, does not receive response bag still, then illustrates terminal, the intelligent network in the application
Join vehicle device, in a dormant state or collapse replay phase or starting when there are no transmitting WLAN rank
Section.
It is being based on transmission control protocol (Transmission Control Protocol, TCP), may be implemented simple
Heartbeat packet, that is, SO_KEEPALIVE.System default is 2 hours palmic rates of setting.Keep-alive of the specific TCP in setting
(KeepAlive) timer sends out a detection TCP data file space (segment) to opposite end, if confiscating acknowledged sequence number
It (Acknowledgement Number, ACK) or resets, after attempting several times, is considered as opposite end and has been not present, finally notice visitor
Family end program, but this method inspection less than machine power off, cable extract, firewall these broken string.And logical layer is handled
Broken string may be also not so benefit reason.Typically just it is used for keep-alive.
In one timer of client terminal start-up, heartbeat (simple communication packet) is constantly sent；Terminal receives heartbeat
Afterwards, give client to send the confirmation of packet, and judge that terminal whether there is that there are mainly two types of methods here: the time difference with simply
Mark.
Optionally, time difference strategy: client records current time (being denoted as T1) after sending a heartbeat.Judgement is fixed
When the device time reach, calculate how long confiscate heartbeat feedback time (T)=current time-T1 (time of above-mentioned record).Such as
Fruit T is greater than some setting value, so that it may think terminal time-out.
Optionally, plain-denotation: for client after receiving a heartbeat, setting connection mark is true；Judgement timing
The device time reaches, and checks all marks, flag bit false's, it is believed that opposite end time-out；Mark is being set as true
false.Plain-denotation is realized than the time difference more simply a bit, but detects the error of the whether middle connection breaking of terminal a little
Greatly.
In the embodiment of the present application, it needs to initialize when starting due to terminal (intelligent network connection vehicle device), it cannot
Just immediately emit WLAN after starting, or the unexpected suspend mode of terminal or routed be restarted automatically all of running quickly during use
It is possible to, so client is needed to need to confirm the state of terminal, can not be only taken up very by way of sending out heartbeat packet
Few memory and expend the state that seldom flow goes detection terminal.
S204, the determining disconnecting between the terminal of control equipment.
Wherein, control equipment can judge the connection with terminal according to the feedback information for sending heartbeat packet, if not existing
The response message from terminal is received in preset time, it is determined that the disconnecting with terminal, it is specifically consistent with S203, here
It repeats no more.
S205, terminal re-emit communication signal.
Specifically, terminal may during connection a certain moment suspend mode or run quickly burst, in this case, terminal hair
The communication signal penetrated interrupts, and the offline state of terminal can be detected in above-mentioned heartbeat packet.I.e. terminal can pass through artificial or itself weight
The mode opened restores the transmitting of communication signal again, it is said herein emit the terminal that refers to can by communication signal to surrounding broadcast,
And the heartbeat packet sent to control equipment responds.
S206, control equipment send heartbeat packet to terminal.
Above-mentioned control equipment by sub thread the state of the inspection terminal in period can when terminal is online
With heartbeat packet one response sent to control equipment, request is initiated the connection to control equipment.
S207, control equipment send the first communication connection and establish request to the terminal；The terminal sends the first confirmation message
And second communication connection establish request to above-mentioned control equipment；It controls equipment and sends the second confirmation message to the terminal.
In the embodiment of the present application, in order to guarantee that the reliable transmissions of data, client and terminal establish TCP connection, TCP connects
Connecing is that one kind establishes a kind of logical communication link between two transmission users, so that communicating pair all confirms that other side is the transmission of oneself
A kind of connection of connection end point.TCP is a kind of logical towards connection (connection guiding), reliable, based on byte stream transport layer
Believe agreement, in view of communication reliability requirement, mostly uses TCP as communication protocol greatly.
Specifically, after middle control starting, start serviced component, serviced component among the above creates sub-line using thread pool
Journey is divided into the process of three-way handshake to create with the connection of terminal.
It controls equipment (control device of vehicle) and sends the first connection request to terminal first, send a band synchronizing sequence
The TCP message of (Synchronize Sequence Numbers, SYN) mark is numbered to terminal, Client sets flag bit SYN
It is 1, client enters SYN_SENT state, waits terminal check.
Terminal is in the state for monitoring (LISTEN), and in the present embodiment, terminal (intelligent vehicle networked devices) is being listened to
From the connection request of the control device TCP port of same vehicle, after terminal receives SYN packet, need to confirm that client is sent
SYN, specific terminal sends to client with ACK flag and with the message of SYN flag, the message with ACK flag be used for
The first communication connection that client confirmation receives client transmission establishes request, and the message with SYN flag is used for terminal to visitor
The second communication connection that family end is sent establishes request, sends the packet to client to confirm connection request, terminal enters
SYN_RCVD state.
After client receives confirmation, terminal is sent the packet to, client and terminal enter ESTABLISHED shape
State, ESTABLISHED represent the connection of an opening, and data can send opposite end to, complete three-way handshake, subsequent client with
It can start to transmit data between terminal.
S208, terminal send vehicle condition data and flow to control device.
Specifically, after the completion of connection, terminal, that is, above-mentioned intelligent network connection vehicle device can acquire the condition information of the vehicle,
And it is converted into data and is sent to control device.
