Embodiment 1

[0060] Such as figure 2 As shown, an avionics simulation environment UDP network packet debugging device, figure 2 Hollow arrows indicate the data flow direction, and solid arrows indicate the control flow direction, including:

[0061] Main frame module, data engine module, data analysis module, data recording module, data playback module, data recording file.

[0062] Data engine modules such as image 3As shown in , it is used to specify the local network card, and obtain all the data packet information passing through the network card, filter the data packets according to the needs, and transmit useful information to the main frame module;

[0063] Among them, when screening, there are generally two types of data packet protocols passing through the network card, TCP and UDP, and the transmission methods include unicast, multicast, and broadcast. Since the general simulation environment protocol only uses UDP, the transmission method only uses unicast. and multicast, ...

Embodiment 2

[0084] The present invention also provides an avionics simulation environment UDP network data packet debugging method, using the avionics simulation environment UDP network data packet debugging device of the first embodiment, comprising:

[0085] 1) Data screening step: used to specify the local network card, and obtain all data packet information passing through the network card, and filter the data packets as required;

[0086] 2) The main frame step is used to provide a human-machine interface, control the start of the data screening step, save, load, and clear the data packet, monitor the information of the data packet passing through the network card, and set the information of the monitoring port;

[0087] 3) a data recording step, for recording the data packet received in the step 2) into a data file;

[0088] 4) a data analysis step, for analyzing the data file recorded in step 3) or the data recorded in step 2);

[0089] 5) The data replay step is used to replay th...
