Described upgrading processing subelement is used for: after receiving upgrading processing signal, carries out upgrading response packet burst and processes；
Described state callbacks processes subelement and is used for: after receiving state callbacks process signal, and radio-frequency module message is converted to master-slave communication message, sends to upper strata master control by release semaphore.
10. the light load radio-frequency module managing device of the MROF system that is applied to as according to any one of claim 6 to 9, it is characterised in that: this device also includes heartbeat packet transmitting element and heartbeat packet receives unit；
Described heartbeat packet transmitting element is used for: fill socket addresses information and heartbeat packet payload buffer memory；And populated heartbeat packet buffer memory interval special time is constantly sent to light load radio-frequency module；
Described heartbeat packet receives unit and is used for: fill purpose socket addresses information, records initial time；Whether the descriptor of detection socket is unreadable, if so, set channel failure, and when needs continue cycling through detection, whether the descriptor again detecting socket is unreadable；
If it is not, check the heartbeat packet whether having light load radio-frequency module to send in passage, if so, set passage is normal, updates initial time, and when needs continue cycling through detection, whether the descriptor again detecting socket is unreadable；
Otherwise, it is judged that whether current time is big with the difference of initial time at fixed time, if so, set channel failure updates initial time, and when needs continue cycling through detection, whether the descriptor again detecting socket is unreadable；If it is not, when needs continue cycling through detection, whether the descriptor again detecting socket is unreadable.
