Problems solved by technology

In order to reduce the consumption of human resources, the remote centralized control method is usually used to carry out the test. Because the mechanical hydraulic product test equipment of the turboshaft turboprop engine is a non-standard test equipment, the functions and control methods of different equipment are quite different, and currently only the test can be realized. The remote start and stop control of the equipment, the execution of the specific working steps of the test equipment depends on the local automatic control program, the editing of the automatic control program is difficult, and the technical level of the test operators is high.

Abstract

The invention discloses a remote centralized system of aero-engine hydraulic product test equipment. Comprising a test equipment industrial control module used for executing test steps of an automatic process file; the centralized control system operation server is used for operation management of the system; the remote control module is used for compiling an automatic process file and sending a command for executing the automatic process file after logging in the centralized control system operation server; the remote scram button is used for realizing remote scram; the central switch is used for data interaction among the test equipment industrial control module, the centralized control system operation server and the remote control module; the sudden stop PLC master station is used for realizing automatic matching of the remote control module and the sudden stop button and sending a sudden stop instruction to the sudden stop PLC slave station; and the sudden stop PLC slave station is used for receiving the sudden stop instruction and sending the sudden stop instruction to the test equipment. According to the invention, centralized and standardized control of non-standard test equipment is realized, and potential safety hazards caused by network communication faults are avoided.

Description

technical field [0001] The invention belongs to the technical field of aero-engine testing, and in particular relates to a remote centralized system and control method of aero-engine hydraulic product testing equipment. Background technique [0002] During the product development process of aero-engine fuel control system, a life test is required to verify whether its service life meets the design requirements. Each product needs to occupy one test equipment for life test, and is equipped with one test operator to operate. The structure of mechanical hydraulic products of turboshaft turboprop engine is complicated, and the test process involves the operation of various control commands such as pressure, speed, and electronic control signals. The operation steps are complicated and require high technical level of operators. With the improvement of the product design level, the life of the product has increased significantly, and the hours of life testing have also increased ...
