Abstract:

The spot instrument apparatus of digital electro-hydraulic control system is an instrument designed for the digital electric hydraulic control system equipped for steam turbine in the field. The traditional check method of digital electro-hydraulic control system is a combined operation based on oscilloscope and signal generator.The traditional check method has many features ,such as complicated operation, lowly real-time, undefined test results.This paper presents spot instrument apparatus design of digital electro-hydraulic control system, not only can detect the output signal of digital electro- hydraulic control system, but also can provide the desired signal for the digital electric-hydraulic control system, and ultimately the computer controls the detection process and displays the detection results.The spot instrument apparatus of digital electro-hydraulic control system includes double STM32 implements the hardware function and Smartpro implements configuration.After the experiment, this system can be used for monitoring and detection of digital electrical hydraulic control signal system module equipped for steam turbine in time,not only improving the security of the field module,at the same time to improve the level of automation.
