Then, subsystem initial phase is monitored, V/UHF radio station are subjected to initial setting up according to parameter preset, parameter includes：It is logical
Believe frequency, business model, cipher mode；
Then, wireless network being opened and establishes, and opens network roll-call, starts polling protocol；
Then, period statistical monitoring station networking situation, it is networking/logout state to mark member according to monitoring station response situation；
Then, the period by network operation state reporting to monitoring system；
Then, receive come self-monitoring system remote control signaling, local cache queue is entered according to destination address, wait for this into
After the roll-call opportunity of member reaches, by calling the roll, packet is sent to corresponding monitoring station；
Then, by after the data parsing from monitoring station, monitoring system is sent to according to the form of agreement；
Poll processing agrees as follows：
To the member's sending time message to network for the first time, complete between master-salve station pair when process；
Start the calling to slave station successively, roll-call data wait for the response of the member after sending；
After receiving response or waiting for time-out, continue to call next slave station.
