Design of Parameter Polling Instrument for Fast Neutron Criticality Facility

In order to satisfy the requirement on the measurement and control system of the fast neutron criticality facility,the parameter polling instrument for the fast neutron criticality facility is designed for the real-time monitoring of the operation of the monitoring device,by integrating the intelligentized instrument with the virtual instrument technology.The configuration and design of the instrument is introduced in this paper.Experiment results show that the interference immunity,consistency,maintainability of the parameter polling instrument has been improved and satisfies the expected requirements.
