Weak signal detection and transmitting module of neutral beam injector control system

The invention discloses a weak signal detection and transmitting module of a neutral beam injector control system. The module comprises an FPGA control module and a light power generation module, wherein the FPGA control module is in control connection with a weak signal processing module, an analog signal acquisition module and a bus communication module; a signal output end of the weak signal processing module is connected with a signal input end of the analog signal acquisition module; and the FPGA control module is in communication connection with a system bus through the bus communication module. The module can intelligently adjust the weak signal detection and transmitting process to achieve high-speed transmission and high-voltage isolation of weak signals.
