Description

technical field [0001] The invention mainly relates to fusion experiment detection technology and digital signal processing technology, in particular to a weak signal detection and transmission module of a neutral beam injector control system. Background technique [0002] Today, with the development of information technology, data acquisition and processing methods are becoming increasingly diverse and intelligent. In large-scale automation control, a large number of distributed monitoring and distributed control systems process and transmit a large amount of underlying information data to remote monitoring terminals to provide decision-making for operation or management personnel. The sensor cluster of the control system converts the state of the system into the required signal, and the detection and transmission system transmits the information data to the data processing controller. The application of some embedded chips with preliminary data processing functions makes ...

Problems solved by technology

In this complex electromagnetic environment, the existing detection and transmission technologies and equipment cannot satisfy the requirements of the control system at the same time in terms of weak signal detection, high voltage isolation of 100,000 volts and above, intelligent adjustment, and fast transmission. Get good system application where required

At present, some transmission equipment has good weak signal detection and high voltage isolation characteristics, but the signal acquisition rate and accuracy are limited; some have high data acquisition and transmission rates, but cannot isolate high voltage and shield electromagnetic waves. interference

These circumstances limit the further development of fusion control systems in high voltage isolation and real-time applications in some respects
