storing the subscribed sampling data from the optical communication module into a cache region through a high-speed data bus;
carrying out digital filtering processing on the digital sampling data in the cache region, filtering high-frequency components, and carrying out protection starting and action logic calculation;
and when the current and voltage protection starting and action conditions in the parameter setting are met, the tripping command is sent to the optical communication module through the high-speed data bus.
8. The station domain protection measurement and control integrated device supporting hot plug management according to claim 1, wherein the measurement and control DSP module is specifically configured to,
storing the sampling data subscribed from the optical communication module into a cache region through a high-speed data bus, performing digital filtering processing on a digital sampling signal in the cache region, filtering out high-frequency components, calculating the filtered data through DFT (discrete Fourier transform), completing analog quantity calculation, and sending the calculated analog quantity to a CPU (central processing unit) module through the high-speed data bus;
the measurement and control DSP module receives a remote control instruction sent by the CPU module through a high-speed data bus, checks whether the received remote control instruction is interlocked and prevents the error requirement according to the currently collected internal and external state signals, and sends the remote control instruction meeting the error prevention requirement to the optical communication module through the high-speed data bus.
9. The station domain protection, measurement and control integrated device supporting hot plug management according to claim 1, wherein the power module is in a dual power supply mode and is an alternating current or direct current power supply.
