the mode control module is used for switching the A module into a normal frequency band and switching the B module into an emergency frequency band when the front-end equipment which is not connected with the network does not exist; the alarm information is preferentially reported from the emergency frequency band; when the emergency frequency band is in a non-idle state, reporting the alarm information from the normal frequency band;
the traversing module is further used for traversing and refreshing the device table for the second time and inquiring whether the front-end device with the networking failure exists;
the equipment network access module is further used for sending a second networking frame to the front-end equipment in a normal frequency band when the front-end equipment with networking failure exists; the A module waits for receiving the response of the front-end equipment, wherein the response timeout time is 2.8S; detecting a value of a second retransmission counter when no response or response timeout of the front-end device is received; when the value of the second retransmission counter is smaller than or equal to 1, adding 1 to the value of the second retransmission counter, and jumping to the step that the A module transmits a second networking frame to the front-end equipment in a normal frequency band for execution, otherwise, marking that the networking of the front-end equipment fails, resetting the value of the second retransmission counter, jumping to the equipment table for traversing the equipment for the second time, refreshing the front-end equipment in the equipment table, and inquiring whether the networking failure exists or not;
the mode control module is also used for issuing a command for exiting a quick CAD mode when the front-end equipment with networking failure does not exist;
and the completion module is used for exiting the networking mode and ending the networking.
