Abstract

The invention relates to a testing technology for a rotary transformer signal calculating module. According to the testing technology, a power supply system, a rotary transformer signal generation system, and a displaying and recording system. To be specific, the power supply system consists of a 24-V direct-current power source, a power source control unit and a power source monitoring unit and is responsible for testing power source management and module powering; the rotary transformer signal generation system including a DSP, a CPLD, and a digital rotary transformer converter carries out communication with a computer system through a serial port, receives a computer instruction for controlling, generates a designated speed signal, converts the signal into an alternating-current simulation signal, and provides inputting for the rotary transformer calculating module; and the display and recording system including an integrated industrial personal computer, an operating system, display control software, a storage system and an automatic testing system is used for receiving data from the rotary transformer signal generation system, carrying out a series of processing of alignment, sorting, data statistics comparison and determination on the data to give out a testing result. The provided testing technology has the characteristics of no mechanical transmission, simple debugging, accurate controlling, and convenient generation of the rotary transformer signal in the complex form; and the electromechanical integration development demand can be satisfied.

Description
