The operation method further includes the master slave mode switching method of IOT devices, the master slave mode switching method
Including automatically switching and two big step of automatic decision, the automatic switchover step was both non-master when IOT devices start referring to Fig. 7
Machine pattern, nor slave mode, after judging according to received broadcasting data signal, enter back into corresponding operating mode, in star
In networking, the IOT devices of host mode IOT devices broadcasting number of the phase all working in slave mode on unified channel is operated in
According to bag, the IOT devices monitor channel and received data packet of slave mode are operated in, then number is sent to host in a manner of unicast
According to.IOT devices start after, if received in the time interval of setting other IOT devices for being operated in host mode send it is wide
Multicast data, then into slave operating mode；
If the broadcast data that other IOT devices for being operated in host mode are sent is not received in the time interval of setting,
Due to having to possess 4G LTE abilitys to communicate as host, it is a criterion whether to be inserted into correct SIM card, because
Whether IOT devices need the SIM card for detecting insertion effective at this time for this：
If SIM card is invalid, IOT devices resume waiting for broadcast data, this is because other IOT devices detection SIM is effective
Afterwards, can start to send broadcast packet, detection at this time can skip restarting process, shorten equipment and start the time.And receiving broadcast number
Enter slave operating mode according to rear, if not receiving broadcast data in the time interval of setting, IOT devices are restarted；
If SIM card is effective, it is to be broadcast that IOT devices are random etc., and enters slave operating mode after broadcast data is received,
IOT devices enter host work pattern if broadcast data is not received.Herein, detect that SIM card can be again random etc. after effective
It is to be broadcast, it is in order to avoid producing host after two IOT devices for being provided simultaneously with master capability (i.e. SIM card is effective) while startup
Conflict, therefore, IOT devices can wait a random time set after detecting that SIM card is effective, determine without other IOT
After device is operated in host mode, just into host work pattern.
For the automatic decision step referring to Fig. 8, one group of timer built in the IOT devices, is operated in host mode
IOT devices can be sent at set time intervals to the whole network and include the broadcast data of timestamp, be operated in the IOT of slave mode
After device receives broadcast data, the content and signal strength of broadcast data are analyzed, if signal strength is normal, and broadcast data
Timestamp and the machine time it is more errorless, then IOT devices will reset built-in timer；If IOT devices do not receive broadcast number
According to or timestamp and the machine time are wrong or signal strength is abnormal, then the built-in timer of IOT devices will not be reset, and can one
Straight cumulative, the timer expired after the time interval more than setting, then IOT devices are restarted and to trigger automatic switchover step again true
Surely host mode or slave mode should be operated in.
Be operated in the IOT device Maintenance free slave status lists of host mode, be operated in the IOT devices of slave mode without
Need to be operated in host mode IOT devices communicate, you can judge be operated in host mode IOT devices and network environment whether
Normally, and with this itself switching working mode is controlled so that control complexity substantially reduces.
