Embodiment 1
[0035] Take a typical power distribution DTU terminal as an example. A power distribution DTU terminal generally has at least 8 channels of interval analog data acquisition, 30 channels of digital input acquisition, 8 groups of remote control opening and closing switches, 2 channels of Ethernet communication hardware interfaces, and traditional three-stage overcurrent protection , Zero-sequence current protection, analog quantity acquisition and display, remote control, five-proof interlocking, and 101 / 104 communication with the master station.
[0036] According to the logic function, the terminal is mapped to the main protection control function plug-in, DI input function plug-in, DO output function plug-in, analog sampling function plug-in, standard communication function plug-in virtual configuration into five distributed virtual function plug-ins, and then map to achieve corresponding Distributed virtual plug-in function. The functions of each plugin are as follows:
