Multi-mode output circuit testing system capable of carrying out resolving in real time

Abstract

A multi-mode output circuit testing system capable of carrying out resolving in real time comprises a power source, an analog signal source, an upper computer and a lower computer. The analog signal source is used for simulating output of a rotary transformer, and sine signals, cosine signals and reference signals are generated to be used as input signals of a tested output circuit. The upper computer sends out a testing order to the lower computer, the lower computer generates corresponding control signals according to the order to control a timer counter function and a constant-number timing function of the tested output circuit in real time, a bus interface is used for monitoring fast-rotating protection signals and collecting data of the tested output circuit, the data are processed by the lower computer and then are sent to the upper computer through a communication interface in real time, and the upper computer displays and stores testing results. The system can flexibly send testing orders to the tested output circuit, and collect testing results on the tested output circuit in real time, and system function expandability is enhanced.
