Problems solved by technology

[0004] The testing, maintenance and on-site installation and debugging of the gate hoist equipment require the use of measuring instruments to test the performance of the absolute encoder to accurately detect the opening of the on-site gate, otherwise the final data will be inaccurate or the gate will be incorrect during installation and commissioning. Hoist causing damage
And there is currently no portable device for testing absolute encoders, which can simultaneously detect and provide on-site absolute encoder data signals to adapt to site requirements under various conditions and at various construction stages

Abstract

The invention provides an absolute value encoder signal measuring and control instrument and a detection method thereof. The absolute value encoder signal measuring and control instrument comprises a shell. A single chip microcomputer, an SSI interface conversion circuit and an RS-485 conversion circuit are arranged inside the shell. The single chip microcomputer is respectively in interactive connection with the SSI interface conversion circuit and the RS-485 conversion circuit. SSI communication input and output interfaces and RS-485 input and output interfaces are formed in the side wall of the shell. By means of the absolute value encoder signal measuring and control instrument, energy loss caused by actual operation of the instrument can be reduced, potential unsafe factors caused by the energy loss can be reduced, and grading installation, debugging and acceptance inspection of a large scale system device are facilitated; therefore safety and reliability in the hydraulic device production, installation and maintenance processes are improved, the absolute value encoder signal measuring and control instrument is suitable for the site environment under the various conditions, and the management level and working efficiency of hydraulic engineering construction are improved.
