Step 309, if it is determined that the corresponding data type of bus input data data type corresponding with equipment identification information
It is inconsistent, generate data processing request.
Wherein, data processing request includes target device identification information.
If it is determined that the corresponding data type of bus input data data type corresponding with the equipment identification information is inconsistent,
Then it fails to match, shows the data type of bus input data not among the corresponding data type of equipment identification information, into one
Step shows that the equipment can not be handled bus input data, then generates data processing request, needs other equipment auxiliary pair
Bus input data is handled.
Specifically, when equipment can not be handled the bus input data received, number will be inputted according to bus
According to data type generate data processing request, in order to which the bus input data that other equipment can not handle the equipment carries out
Processing.
It should be noted that data processing request be generated according to the equipment identification information in device events table, for example,
