Design of Safety Analog Voltage Acquisition Module
Based on the demand of trackside control unit about analog voltage safety acquisition, a safety analog voltage acquisition module is designed in this paper. it is implemented by using the method of heterogeneous hardware design and two out of two software design. The module realizes the safety acquisition of single ended and differential voltage signals within the specified frequency range for the first time. It has the characteristics of miniaturization and lightweight. It is suitable for application scenarios with safety acquisition requirements in the field of rail transit.
