Block, for detecting the current chain between communication module 120 and remote monitoring server after receiving inspection linking status instruction
Connect state.Submodule is rebuild in link, for sending when state-detection submodule detects that current link state disconnects for connection
Link instruction rebuilds linking between communication module 120 and remote monitoring server.Submodule is operated normally, in communication mould
It is rebuild between block 120 and remote monitoring server after linking, control microcontroller 110 is normally carried out the interaction of data.Heartbeat letter
Sending module is ceased, for sending heartbeat message to remote monitoring server by communication module 120.Response receiving submodule is used
In the response message that reception remote monitoring server issues after receiving heartbeat message, and when not receiving response message,
It returns to link and rebuilds submodule, submodule is rebuild by link and carries out linking between communication module 120 and remote monitoring server
It rebuilds.
For example, it may include: step S610, press when link self diagnosis module carries out link self-test refering to Fig. 7
It is sent according to predetermined period and checks linking status instruction.Step S620, after receiving inspection linking status instruction, detection communication mould
Current link state between block 120 and remote monitoring server.Step S630 detects current chain in state-detection submodule

When reissuing to remote monitoring server, it can be realized by following steps.
Refering to Fig. 8, when car-mounted terminal 100 goes offline situation, first by step S510, microcontroller 110 into
During row normal information reports, the Current Communications Status between microcontroller 110 and remote monitoring server is detected (that is, logical
Believe the current link state between module 120 and remote monitoring server).When it is abnormal for finding Current Communications Status, execute
Step S520 sends corresponding instruction and carries out link reconstruction.Link rebuilds successfully after, can parallel execution of steps S530, reality
When send and currently collect and carry out dissection process and be packaged treated all data.Step S540, by memory 150
Not sent data packet is reported transmission again after reading not sent data packet and going offline.Realize the number that goes offline as a result,
According to reissue, to guarantee the integrality and accuracy of reported data.
Refering to Fig. 9, when car-mounted terminal 100 breaks down, first by step S510 ', carried out just in microcontroller 110
During normal information reporting, the current operating conditions of car-mounted terminal 100 are detected.Detecting that current operating conditions are 3 grades of failures
When, step S520 ' is executed, sends the real time data in the first preset time period according to predetermined period.Herein, it needs to illustrate
It is that predetermined period can be 1s, and the value of the first preset time period can be 30s.It is counted in real time that is, sending 30s as the period using 1s
According to.Then step S530 ' is executed, the data of the second preset time before fault point are sent, to realize data when failure occurs
Reissue.The value of second preset time can be 30s.That is, 30s reissues data before sending fault point, to avoid failure hair
The loss of data, equally also ensures the integrality and accuracy of reported data when raw.
As a result, in data link exception, such as go offline or other failures, terminal equipment being capable of real-time reports
Information is stored, and after data link restores normal, completes to reissue in the free time for sending real-time report data
The reported data of storage.When 3 grades of failures occurs in vehicle, answer reporting fault that the vehicle data of front and back 30s, intelligence sample week occurs
Phase should not exceed 1s, and the data before failure occurs are transmitted in the form reissued.
