Specific embodiment
Below with reference to attached drawing 1 to 3, the present invention is described further, but should not limit protection of the invention with this
Range.For convenience of explanation and understand technical solution of the present invention, illustrates the used noun of locality with the exhibition of attached drawing institute below
Subject to the orientation shown.
A kind of frequency slot transmitting management system, the system are received by receiving antenna, transmitting antenna, GPS time signal
Module, synchronization control module, signal generating module, interference signal transmitting module and micro-control unit composition；It is characterized in that,
The micro-control unit includes:
Equipment self-inspection control module, for GPS time signal receiving module, signal generating module and synchronously control mould
Block carries out function self-test；
GPS time signal control module is received, it is accurate for the reception signal message according to GPS time signal receiving module
Location frequency time slot carries out time calibration, and provides time service parameter；
It is synchronous with signal slot in interference signal generation module for driving signal module to occur for synchronization signal module；
Control module is opened and closed, module occurs for the starting in target time slot and shutdown signal；
Time correction module is used for detection time synchronous error, beyond return synchronization signal module after error fault tolerance, weight
It is new to execute the synchronous control of signal.
System through the invention is come the method for realizing slot transmission management specifically:
(1) system electrification is initialized and is started to work；
