2, the whether successful connection of active and standby communication module is judged.If all successful connections of active and standby communication module, send data by main communication module to monitor supervision platform, standby communication module (such as, second communication module) timed sending heartbeat packet, ensures that standby communication module is connected with the communication link of monitor supervision platform; If the non-successful connection of main communication module, standby communication module success, then send data by standby communication module to monitor supervision platform.If active and standby communication module is all unsuccessful, continue step 1.
3, in main communication module and monitor supervision platform normal course of communications, if continuous 3 secondary data send unsuccessfully, then think that main communication module is destroyed, be then switched to standby communication module immediately and communicate with monitor supervision platform.Wherein, counting can be realized by the internal counter of processor.
As shown in Figure 5, when car-mounted terminal 100 needs to connect two and above monitor supervision platform simultaneously, the working method that car-mounted terminal 100 communicates with monitor supervision platform 201,202 can adopt " bright ", " secretly " communication module walks abreast.Its workflow is as follows:
1, artificial " secretly " communication module of distributing is connected on the high monitor supervision platform of fail safe, reliability requirement, be decided to be important monitor supervision platform (such as, monitor supervision platform 201), " bright " communication module connects remaining monitor supervision platform, be decided to be secondary monitor supervision platform (such as, monitor supervision platform 202).
2, car-mounted terminal works on power, and " bright ", " secretly " communication module are set up communication link with corresponding monitor supervision platform respectively and connected, and this link connects can adopt TCP/IP or udp protocol connection.
3, after link successful connection, " bright ", " secretly " communication module send data respectively to the monitor supervision platform of correspondence.
If 4 " bright ", " secretly " communication module occur that link connects abnormal conditions, the then corresponding communication module of processor reset in transmission data procedures, re-establish communication link and connect.
The double-channel car-mounted terminal that the utility model provides, adopts " bright " " secretly " two communication modules as data transmission channel, to ensure that the reliability of transfer of data.Although add a communication module than car-mounted terminal of the prior art, add cost, ensure that the reliability of the monitoring of hazardous vehicles such as " two visitor one danger ", reduce the loss of people's life and property.
The double-channel car-mounted terminal provided by the utility model execution mode, when lawless person deliberately destroys communication line, such as, is pulled out SIM card, pulls out antenna, screened shielded antanna etc., still can communicate with monitor supervision platform.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned execution mode; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection range of the present utility model.
It should be noted that in addition, each the concrete technical characteristic described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode.In order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible compound mode.
In addition, also can carry out combination in any between various different execution mode of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
