Abstract
The invention belongs to the field of message processing, and in particular relates to a method and a device for dividing and selecting a random time slot in real time. To solve the problem in the prior art, the invention provides a method and a device for dividing and selecting a random time slot in real time. According to the invention, the type and the amount of a message are transmitted as required; transmission time channels and transmission time slots are established for message of different types in combination with pulse per second, so that the working efficiency of the system is improved. The method comprises the following steps: firstly, dividing time periods for transmitting an FIS-B (Flight Information Service-Broadcast) message and a TIS-B (Traffic Information Service-Broadcast) message according to pulse per second, obtaining the initial configuration value of an FIS-B message transmission channel according to a CPU (Central Processing Unit) communication interface, and determining a specific FIS-B message transmission channel; secondly, obtaining the initial configuration value of an offset of a TIS-B message transmission time window according to the CPU communication interface, setting the TIS-B message transmission time window, and further dividing the TIS-B message transmission time window; finally, updating the message transmission channel and the time slot according to pulse per second.
