The signal allocation constraint unit constructs a signal processing resource allocation constraint set based on the allocable resource data of the on-board operational amplifier system and filters each signal; the allocation strategy planning unit uses dynamic programming to analyze the allocation strategy of the on-board operational amplifier system with the maximum signal comprehensive processing utility when each signal to be processed participates in resource allocation; the allocation adjustment gain analysis unit is used to calculate the allocation adjustment gain of the allocation strategy of the maximum signal comprehensive processing utility for each signal to be processed; the processing order decision unit determines the resource allocation processing order of each signal to be processed based on the allocation adjustment gain of each signal to be processed; the processing order correction unit adjusts the resource allocation processing order of all signals to be processed based on the maximum signal delay of the on-board operational amplifier system.
