In the case of cyclic transmission of dual digital electrical signals,in order to achieve the directional control and management of individual signal parameters,an electrical control system based on dual digital signal processors is designed.The D/A conversion circuit is used to integrate the electrified transmission power,and the signal main control module is combined to establish a physical application connection between the core control host and the complex programmable logic device to realize the construction of the hardware execution environment of the system.On this basis,the waveform data generation algorithm is established,with the help of dual digital signal monitoring and processing programs,the most basic upper computer software is controlled,the software execution environment of the system is built,and the relevant hardware equipment components are combined to complete the dual digital signal processor-based Electrical control system design.The comparative experiment results show that compared with the conventional relay protection system,the average value of the SDI index in the new electrical control system is higher,which meets the actual processing requirements of the core application host for directional control and management of individual signal parameters.
